Abstract
A drain valve device based on capacitive sensing for a water tank of a toilet includes a drain valve disposed in the water tank of the toilet to control the water tank to drain water; a capacitive sensing control module that opens the drain valve; and an assembly fixture used to connect the capacitive sensing control module to the drain valve to make the capacitive control module and the drain valve form an integration. The assembly fixture connects the capacitive sensing control module and the drain vale to form the integration, so that during assembly of the drain valve, the capacitive sensing control module is affixed to the toilet water tank at the same time. Thus, assembly is simple and convenient, and there is no need to dispose an assembly hole in the water tank cover so the structure is simpler.
