The application relates to an improved vector trap.

Mosquitoes are a form of a vector. The vector refers to an in sect or animal that passes disease from one person to another. Bite of female mosquitoes can transmit dangerous diseases like malaria, dengue fever, and West Nile virus. The female mosqui toes bite animals or human beings to suck out tiny amounts of blood for reproducing. The blood contains protein that allows the female mosquitoes to produce eggs. After this, the female mosquitoes lay their eggs in water. Larvae then hatch from the eggs. The larvae live in the water, straining organic matter from the water for sustenance. The larvae then transform into pupae and the pupae later transform into adult mosquitoes, which then fly away. The period for a mosquito egg to grow in to an adult mosquito is about one week.

US6298011B1 discloses a method for killing mosquito larvae.

The method includes immersing an acoustic transducer in a body of water containing mosquito larvae and energizing the acous tic transducer to cause a resonant frequency in the body of water. The resonant frequency resonates with the air bladder of the mosquito larvae and then traumatizes surrounding tis sue, thereby resulting in death of the mosquito larvae.

US20140202961A1 discloses a system for depleting target organ isms in water. The system includes a waterproof transducer, which is configured for ensonifying or filling a container of water with low intensity sound at one or more ultrasound fre quencies for a duration that is sufficient to prevent matura tion of at least 90% of the target organism. The target organ ism can refer to mosquito larvae. In one implementation, a portable system for depleting target organisms in water in- eludes a control system and a plurality of waterproof trans ducers. The system is configured for ensonifying a surface layer of water with sound having an acoustic frequency range from about 40 kilohertz to about 100 kilohertz and having a power concentration range from about 35 milliwatts per milli liter to 100 milliwatts per milliliter for a duration that ranges from about 1 to about 100 seconds.

It is an object of the application to provide an improved mos quito eradication device.

The application provides an improved mosquito eradication de vice for providing a suitable breeding site for mosquito lar vae and for eradicating or killing the larvae.

The mosquito eradication device includes a container for col lecting and storing rain water. The stored rain water, which is often still, provides a suitable breeding site for the mos quito larvae .

The mosquito eradication device further includes an ultravio let (UV) light generation unit to generate UV light and to emit or transmit the generated UV light to the container. The UV light refers to light having wavelengths that are near or within ultraviolet light range of 10 nanometer (nm) to 400nm. The transmitted UV light acts to attract female mosquitoes to lay eggs in the water of the container. The eggs later grow into mosquito larvae. Since the mosquitoes are more active at night, the UV light generation unit is often energized during the night .

The mosquito eradication device also includes a water level sensor for measuring a water level of the water in the con tainer. The water level sensor may measure a depth of the wa- ter level or may determine a range of depth of the water lev el .

The mosquito eradication device further includes an ultrasound generation unit for generating ultrasound waves with a prede termined frequency or wavelength. The ultrasound waves can have operating frequencies of more than 20 kilohertz. The gen erated ultrasound waves are directed towards the water of the container, where the mosquito larvae are bred. The transmitted ultrasound waves act to resonate with air bladders of the mos quito larvae for traumatizing tissues surrounding the air bladders to kill the mosquito larvae.

The mosquito eradication device also includes a control unit, which is adapted to receive measurements of the water level in the container from the water level sensor.

After the control unit has received a measurement of the water level, it determines a duration for transmitting the ultra sound waves according to the received water level measurement.

The duration is determined such that sound energy of the ul trasound waves are sufficient to kill the mosquito larvae, which are located at different parts or locations in the water of the container, even when the larvae are located farthest from the ultrasound generation unit. When the ultrasound waves travel through the water, their amplitudes are attenuated due to absorption and scattering of the sound waves by particles or impurities in the water, resulting in loss of the sound en ergy. The attenuation or energy loss also increases with the distance that the ultrasound waves travel. This means that the location farthest from the ultrasound generation unit receives the least sound energy. In order to kill the mosquito larvae at the farthest location, the duration of the ultrasound waves is often determined according to the farthest distance that the ultrasound waves travel.

The farthest distance also corresponds to the measurement of the water level of the container. The higher the measurement of the water level, the longer the farthest distance, and vice versa. In other words, the control unit uses the measurement of the water level to determine the duration for transmitting the ultrasound waves.

The control unit later activates or energizes the ultrasound generation unit to transmit the ultrasound waves with a prede termined frequency for said determined duration. The mosquito larvae in the water are then subjected to the ultrasound waves, wherein the ultrasound waves traumatize the larvae suf ficiently for preventing the maturation of the mosquito lar vae .

In short, the improved mosquito eradication device effectively attracts female mosquitoes to lay eggs into water for growing into larvae and then effectively kills the larvae by transmit ting ultrasound waves for a sufficient period that is deter mined according to a water level of the water in the contain er, which can change over time. The duration can be shortened when the water level of the container is low. This saves ener gy, comparing with other devices that transmit ultrasound waves with a fixed duration, which

The ultrasound generation unit can be provided near to a bot tom of the container. In other words, the ultrasound genera tion unit can be provided at an outer surface of the bottom of the container, below the bottom of the container, or at a po sition that is inside the container and is near to the bottom of the container. This allows easy implementation. In one implementation, the ultrasound generation unit provides ultrasound waves with a predetermined frequency of about 42 kilohertz and the ultrasound waves are transmitted with a pow er of about 50 watts. The duration of transmitting the ultra sound waves ranges from 5 minutes to 20 minutes.

The ultrasound generation unit can be de-activated when the measured or sensed water level is substantially zero. In other words, the ultrasound generation unit is not energized when the mosquito larvae are essentially absent. This then acts to save energy and operating cost.

The UV generation unit can be provided near to or inside the container. This allows the female mosquitoes to fly towards the UV generation unit and reach the container easily for lay ing eggs into the water of the container.

The UV generation unit can include a plurality of UV light emitting diodes, which are easily available at low cost.

In one embodiment, the mosquito eradication device further comprises a light sensor for detection of an absence of light rays and for transmitting a corresponding detection signal to the control unit according to the detection. The control unit then energizes the UV generation unit according to the detec tion signal. This allows the UV generation unit to transmit UV light at night for effectively attracting mosquitoes, which are most active during the night. The UV generation unit is not energized in the day to save energy.

The mosquito eradication device can further include a battery module for powering the mosquito eradication device. The mosquito eradication device can also include a solar mod ule for selectively charging the battery module. The solar module can refer to a solar panel or a solar cell assembly, which includes a plurality of solar cells. The solar cells act to covert solar radiation into electrical energy for charging the battery module. This allows the mosquito eradication de vice to be power self-sustaining so that it can then be de ployed in remote areas where electricity from power plants is not conveniently available.

The mosquito eradication device can also include an alternat ing current-to-direct current (AC/DC) adaptor module for re ceiving energy from an external source and for selectively charging the battery module. The AC/DC adaptor module can be electrically connected to an AC power grid for receiving an AC voltage. The AC/DC adaptor module later coverts the received AC voltage into a DC voltage for charging the battery module. This allows the mosquito eradication device to be powered even during periods where daylight is sufficiently available.

The application also provides a method for operating the mos quito eradication device mentioned above. The method includes a step of collecting and storing rain water in a container and a step of transmitting UV light to the container to attract female mosquitoes for laying eggs, and for breeding mosquito larvae. The method further includes a step of measuring a wa ter level of the water in the container and a step of deter mining a duration for transmitting ultrasound waves according to a measurement of the water level. The method also includes a step of generating the ultrasound waves with a predetermined frequency and transmitting the generated ultrasound waves for the determined duration to prevent maturation of the mosquito larvae . The method can further include a step of measuring an absence of light rays for activating the transmission of the UV light.

The method can also include a step of selectively charging a battery module of the mosquito eradication device with a solar module .

Referring to Fig. 2, the mosquito harvest module 16 includes a mosquito breeding container 22 and an ultraviolet light (UV) generation unit 25, which is placed inside the mosquito breed ing container 22.

The container 22 has a substantially cylindrical shape and it is made of metal. In a general sense, the container 22 can al so be made of other material. The container 22 includes multi ple slits 28 that are provided near a rim of the container 22. Each of the slits 28 is covered with a water filter.

As seen in Fig. 3, the ultraviolet light generation unit 25 includes a plastic housing 32, a control printed circuit board (PCB) 37, a plurality of ultraviolet light emitting diodes (UV LEDs) 42, a light sensor 38, a water level sensor 40, and a microcontroller 48. The UV LEDs 42, the water level sensor 40, and the microcontroller 48 are mounted to the control PCB 37 while the light sensor 38 is mounted on an outer surface of the plastic housing 32. The control PCB 37 is located inside the housing 32, which is placed near a central position inside the container 22. The microcontroller 48 is electrically con nected to the UV LEDs 42, to the light sensor 38, and to the water level sensor 40.

In one implementation, the microcontroller 48 is adapted to process 8-bit, 16-bit, or 32-bit data and it has an embedded memory module. The plurality of the UV LEDs 42 includes 8 pieces of UV LEDs. The light sensor 38 includes an ambient light sensing device while the water level sensor 40 includes a capacitive sensing device.

Referring to the mosquito eradication module 19, it includes a substantially cuboid housing 41, a main printed circuit board (PCB) 55, an ultrasound generation device 43, and a battery module 56. A part of the ultrasound generation device 43 and the battery module 56 are provided on the main PCB 55, which is located inside the housing 41. As better seen in Fig. 4, the battery module 56 is electrically connected to the solar panel 53, to the AC/DC adaptor module 60, and to the ultra sound generation device 43.

The battery module 56 includes a solar charger 59 with a maxi mum power point tracking (MPPT) device, a chargeable battery 62, a voltage regulator 65. The solar charger 59 is electri cally connected to the battery 62. The battery 62 is electri cally connected to the voltage regulator 65, which is electri cally connected to the ultrasound generation device 43. The voltage regulator 65 is also electrically connected to the mi crocontroller 48, to the UV LEDs 42, to the light sensor 38, and to the water level sensor 40 of the mosquito harvest mod ule 16.

In one implementation, the battery module 56 includes a solar charger with a current limiting circuit, a lithium-ion battery with an operating voltage of 11.1 volts, and a voltage regula tor of 5 volts .

The battery module 56 further includes a single-pole-double- throw (SPDT) switch, which is not shown in the drawing for simplicity. The SPDT switch includes a first input terminal, a second input terminal, and an output terminal. The first input terminal is electrically connected to the AC/DC adaptor module 60 while the second input terminal is electrically connected to the solar panel 53. The output terminal is electrically connected to the solar charger 59.

The ultrasound generation device 43 includes a driving unit 46, a transformer 45, and an ultrasound transducer 47. The driving unit 46 is electrically connected to the voltage regu lator 65 and to the transformer 45. The transformer 45 is electrically connected to the ultrasound transducer 47. As seen in Fig. 3, the driving unit 46 and the transformer 45 are mounted on the main PCB 55 while the ultrasound transducer 47 is attached to an outer surface of a bottom of the container 22.

In use, the mosquito eradication device 1 is often placed in areas, such as wetland areas, which provide suitable breeding habitats for mosquitoes .

The openings and slits of the side surfaces of the casing 13 are intended for blocking and preventing foreign objects, such as leaves, from falling into or entering the mosquito breeding container 22 while allowing mosquitoes to fly through them.

The opening of the top surface of the casing 13 also acts to allow rain water to flow through.

The mosquito breeding container 22 acts to receive the rain water and to store the received rain water. The stored rain water provides a breeding site for female mosquitoes to lay eggs and for the mosquito eggs to grow into larvae and then into pupae .

The slits 28 with the filter near the rim of the container 22 are intended for allowing water to be discharged out of the container 22 when the container 22 overflows while the filter serves to prevent the mosquito eggs, larvae, and pupae in the water from leaving the container 22.

The ultrasound generation device 43 provides a standby mode and an operation mode .

In the standby mode, the ultrasound generation device 43 is not activated and is not energized. In the operation mode, the ultrasound generation device 43 is activated or energized. The energized ultrasound generation device 43 then generates ultrasound waves with a predetermined frequency or wavelength for a specific duration, wherein the generated ultrasound waves are directed towards water inside the container 22.

In detail, the driving unit 46 of the ultrasound generation device 43 is energized to generate alternating electrical sig nals with a predetermined frequency or wavelength for a spe cific duration, and to transmit the generated electrical sig nals to the transformer 45. The transformer 45 then receives the transmitted electrical signals and later transmits corre sponding amplified electrical signals with an enlarged ampli tude to the ultrasound transducer 47. The ultrasound transduc er 47 afterward receives the corresponding amplified electri cal signals and then converts the corresponding amplified electrical signals into ultrasound signals or waves for trans mission towards the water inside the container 22.

In one implementation, the driving unit 46 is adapted to gen erate electrical signals with a predetermined frequency of 42 kilohertz (KHZ) for driving the transformer 45. The transform er 45 later transmits corresponding amplified electrical sig nals of 300 volts or 300VAC to the ultrasound transducer 47. The ultrasound transducer 47 then generates ultrasound waves of 42KHZ with a power of about 50 watt (W) for transmission.

In another implementation, the driving unit 46 is adapted to generate electrical signals with a predetermined frequency that is within a range of 41 KHZ to 43 KHZ. The memory module of the microcontroller 48 acts to store in structions of one or more software programs. The microcontrol ler 48 serves to execute the instructions to control or to di rect operations of the electrical parts of the mosquito eradi- cator 10.

The light sensor 38 is intended for detecting presence or ab sence of light rays and to transmit corresponding detection signals to the microcontroller 48 according to the detection of the light rays. The light sensor 38 transmits a day detec tion signal when the light sensor 38 detects a presence of light rays, which are often present in the day while transmits a night detection signal when the light sensor 38 detects an absence of the light rays, especially at night.

The microcontroller 48 then receives the transmitted detection signals and then activates or deactivates the UV LEDs 42 ac cording to the received detection signals. If the microcon troller 48 receives the night detection signal, the microcon troller 48 later energizes the UV LEDs 42. If the microcon troller 48 receives the day detection signal, the microcon troller 48 does not energize the UV LEDs 42.

When the UV LEDs 42 are energized, the UV LEDs 42 emit UV light to attract mosquitoes to fly to the container 22. The female mosquitoes then lay eggs into the water of the contain er 22.

When the UV LEDs 42 are not energized, the UV LEDs 42 do not emit any UV light .

The water level sensor 40 is used for measuring a water level inside the container 22 and for transmitting a measurement of the water level to the microcontroller 48. The microcontroller 48 then receives the measurement of the water level and later determines a duration for energizing the ultrasound generation device 43 according to the received measurement of the water level .

The duration is determined such that sound energy of the ul trasound waves are sufficient to kill the mosquito larvae, which are located at different parts or locations in the water of the container 22, even when the larvae are located farthest from the ultrasound transducer 47 of the ultrasound generation device 43. When the ultrasound waves travel through the water, their amplitudes are attenuated due to absorption and scatter ing of the sound waves by particles or impurities in the wa ter, resulting in loss of the sound energy. The attenuation or energy loss also increases with the distance that the ultra sound waves travel. This means that the location farthest from the ultrasound transducer 47 receives the least sound energy. In order to kill the mosquito larvae at the farthest location, the duration of the ultrasound waves is often determined ac cording to the farthest distance that the ultrasound waves travel .

The farthest distance also corresponds to the measurement of the water level of the container 22. The higher the measure ment of the water level, the longer the farthest distance, and vice versa. In other words, the microcontroller 48 uses the measurement of the water level to determine the duration for transmitting the ultrasound waves .

In one implementation, the determined duration is zero if the measurement of the water level is essentially zero or below a first measurement range. The determined duration is 5 minutes if the measurement of the water level is within a first meas- urement range. The determined duration is 10 minutes if the measurement of the water level is within a second measurement range, which is higher than the first measurement range. The determined duration is 15 minutes if the measurement of the water level is within a third measurement range, which is higher than the second measurement range. The determined dura tion is 20 minutes if the measurement of the water level is within a fourth measurement range, which is higher than the third measurement range .

After this, the microcontroller 48 activates and energizes the ultrasound generation device 43 for the determined duration.

The energized ultrasound generation device 43 then generates the ultrasound waves with a predetermined frequency or wave length for the specific duration, and later transmits the gen erated ultrasound waves towards the water of the container 22.

The transmitted ultrasound waves later travel through the wa ter of the container 22. The ultrasound waves then resonate with air bladders of mosquito larvae and traumatize tissues surrounding the air bladders for the determined duration to prevent maturation of the mosquito larvae or to kill the mos quito larvae .

Referring to the solar panel 53 and to the AC/DC adaptor mod ule 60, they are intended for providing electricity to the mosquito eradicator 10. The mosquito eradicator 10 can be placed in two different power modes, namely, an AC/DC adaptor mode and a solar battery mode.

In the AC/DC adaptor mode, the AC/DC adaptor module 60, which is electrically connected to an AC power grid 61, is electri cally connected, via the SPDT switch, to the solar charger 59. In detail, a user places the SPDT switch in a first position, wherein its first input terminal is connected to its output terminal while its second input terminal is not connected to its output terminal. The AC/DC adaptor module 60 is then elec trically connected to the first input terminal of the SPDT switch, to the output terminal of the SPDT switch, and to the solar charger 59. The AC/DC adaptor module 60 then receives an alternating current (AC) voltage from the AC power grid 61 and later converts the alternating voltage into a DC voltage for transmitting to the first input terminal, to the output termi nal, and to the solar charger 59.

The solar charger 59 afterward receives the DC voltage from the AC/DC adaptor module 60 and then transmits the DC voltage to charge the chargeable battery 62. The battery 62 later pro vides a predetermined voltage to the voltage regulator 65. The voltage regulator 65 then receives the predetermined voltage and later provides a voltage with a predetermined constant level, for example, 5 volts, for powering the microcontroller 48, the water level senor 40, the light sensor 38, and the UV LEDs 42.

In the solar battery mode, the solar panel 53 is electrically connected, via the SPDT switch, to the solar charger 59, which is electrically disconnected from the AC/DC adaptor module 60.

In detail, the user electrically disconnects the AC/DC adaptor module 60 from the AC power grid 61 and the AC/DC adaptor mod ule 60 does not receive any AC voltage from the AC power grid 61. The user also places the SPDT switch in a second position, wherein its second input terminal is connected to its output terminal while its first input terminal is not connected to its output terminal. The solar panel 53 is then electrically connected to the second input terminal of the SPDT switch, to the output terminal of the SPDT switch, and to the solar charger 59. The solar panel 53 later receives solar radiation and then converts the solar radiation into electrical energy for transmission to the second input terminal, to the output terminal, and to the solar charger 59. The transmitted elec trical energy is later used for charging the battery 62.

In one implementation, the AC/DC adaptor module 60 has a cur rent rating of 4 ampere (A) and is adapted to provide an out put dc voltage of 12 volts (V) to the solar charger 59.

Fig. 5 shows a flow chart 100 of a method for operating the improved mosquito eradication device 1.

The method includes a step 103 of collecting and storing rain water in the container 22.

The mosquito eradication device 1 is then placed in either the AC/DC adaptor mode or the solar battery mode, in a step of 110.

In the AC/DC adaptor mode, the light sensor 38 detects an ab sence of light rays for a predetermined period and then trans mits a night detection signal to the microcontroller 48. The microcontroller 48 later energizes the UV LEDs 42 throughout the night to emit UV light in the container 22 to attract fe male mosquitoes, in a next step 115.

The water level sensor 40 later measures a water level of the container 22 and then transmits a measurement of the water level to the microcontroller 48, in a step 120. The microcontroller 48 afterward receives the measurement of the water level and later, once a day, determines a duration for transmitting ultrasound waves according to the received measurement of the water level, in a step 125.

In a subsequent step 128, the microcontroller 48 energizes the ultrasound generation device 43 to emit ultrasound waves for the determined duration.

In the day, the light sensor 38 detects the presence of light rays for a predetermined period and transmits a day detection signal to the microcontroller 48 for deactivating the UV LEDs 42.

In the solar battery mode, the light sensor 38 detects an ab sence of light rays for a predetermined period and then trans mits a night detection signal to the microcontroller 48. The microcontroller 48 later energizes the UV LEDs 42 for several hours to emit UV light and then enters a sleep state for sav ing energy, in a next step 130.

The microcontroller 48 has a timer for waking up the microcon troller 48 from the sleep state to a working state after a first predetermined period, for example, one week. The micro controller 48 can also be restored to the working state by a signal from the sensors 38 and 40.

The step 130 is repeated every night until the timer reaches an end of the first predetermined period.

After this, the water level sensor 40 measures a water level and then transmits a measurement of the water level to the mi crocontroller 48, in a step 133. The microcontroller 48 afterward determines a duration for transmitting ultrasound waves according to the received meas urement of the water level, in a step 136.

The microcontroller 48 later energizes the ultrasound genera tion device 43 to emit ultrasound waves for the determined du ration. The microcontroller 48 then enter the sleep state again, in a subsequent step 139.

In one embodiment, the improved mosquito eradication device 1 further includes an attachment mechanism for mounting the mos quito eradicator 10 onto a pole. An example of the attachment mechanism is shown in Fig. 6.

Different implementations of the ultrasound transducer 47 are possible .

Instead of the ultrasound transducer 47 being attached to the bottom of the container 22, the ultrasound transducer 47 can be located below or near to the bottom of the container 22, or to be located inside the container 22, and near to the bottom of the container 22.

In a special embodiment, the SPDT switch is replaced by a switching device. The switching device is configured to detect a voltage from the AC/DC adaptor module 60 and to automatical ly switch or place the mosquito eradicator 10 in the AC/DC adaptor mode or in the solar battery mode according to the de tected voltage. In particular, if a predetermined voltage is detected, the switching device places the mosquito eradicator 10 in the AC/DC adaptor mode. If the predetermined voltage is not detected, the switching device places the mosquito eradi cator 10 in the solar battery mode. The improved mosquito eradication device 1 provides several benefits .

The mosquito eradication device 1 can effectively attract and kill or eliminate mosquitoes when they are in a larvae stage of their life cycle. The mosquito eradication device 1 is also portable with a self-sustaining solar panel. This allows the mosquito eradication device 1 to be easily deployed in remote areas, where an AC power grid is not conveniently available.
