POSITION DETECTION CIRCUIT AND ELECTRONIC CIGARETTE

WIPO Patent Application WO/2020/200007

A1

A position detection circuit. The position detection circuit is connected to a processing circuit (200) and is used for detecting whether a placement member is correctly placed, and comprises a first switch module (110) and a first grounding resistor (R1); the first switch module (110) comprises a first end, a second end and a first switch (T1), the first switch module (110) is used for controlling an on/off state of the first switch (T1) according to whether the placement member is placed at a first placement position, the first end of the first switch module (110) receives a system voltage (Vcc), and the second end outputs a first state signal or a second state signal to the processing circuit (200) according to the on/off state of the first switch (T1); and the first grounding resistor (R1) has a first end connected to the second end of the first switch module (110), and a second end grounded. Also provided is an electronic cigarette. The position detection circuit and the electronic cigarette realize automatic detection of whether a placement member, such as the cartridge of the electronic cigarette, is placed at a correct position, so as to prompt a user of whether the placement member has been placed at a corresponding position, thereby improving the user experience.
