CONTROL METHOD FOR SMART TOILET COVER BASED ON DOUBLE INFRARED SENSORS
Document Type and Number:
WIPO Patent Application WO/2023/116120
Kind Code:
A1
Abstract:
A control method for a smart toilet cover based on double infrared sensors, comprises: sensing, by means of a first infrared distance measurement unit (130), a human body approaching a smart toilet cover, and transmitting an approaching signal to a first processor (101) to control a second opening and closing mechanism to open a cover plate (12), the first infrared distance measurement unit (130) having a first sensing distance; controlling the sensing distance of the first infrared distance measurement unit (130) to be shortened from the first sensing distance to a second sensing distance; and activating a second infrared distance measurement unit (131), sensing a human body leaving signal by means of the second infrared distance measurement unit (131), and transmitting the leaving signal to the first processor (101) to implement flushing.
