Title:
WATER LEVEL DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/035708
Kind Code:
A1
Abstract:
A water level detection device, comprising: a touch IC (201), a plurality of multi-gear sensing pads (202), and a water tank (203), wherein the multi-gear sensing pad (202) is used for realizing, according to a change in capacitance of the pad, the identification of multiple gears by one channel. The multi-gear sensing pad (202) comprises: a multi-shape sensing pad for setting gears according to a shape feature thereof, sensing a change in capacitance of the sensing pad when the pad is subjected to water, determining a gear according to the change in capacitance, and realizing the identification of multiple gears by one channel. Compared with the prior art, the present invention has a simpler structure and a lower price, and can reduce the error of water level detection and improve the precision of water level detection.
