Description

Induction flushing valve with handle Technical Field The utility model relates to the technical field of flushing valves, in particular to a sensing flushing valve with a handle. Background Currently, flush valves used in public or household toilets are mainly classified into two main categories, namely purely mechanical flush valves, such as time-lapse self-closing or hand-push flush valves. The valve can push the valve core to open directly or indirectly (such as by using a differential pressure principle) by manually pressing the handle, so as to realize flushing. Its advantages are reliable structure, low cost and no dependence on external power supply. However, the disadvantage is also obvious that the user must directly contact the handle, cross infection is easy to be caused in places where personnel are intensive such as public washroom, and sanitation is poor, and meanwhile, for some inconvenient action people or children, the pressing operation can be laborious, and the situation of forgetting to flush water exists. The other type is an induction type automatic flushing valve, which detects human body signals through an infrared sensor and automatically controls the action of an electromagnetic valve to start and stop water flow. The valve has the greatest advantages of completely non-contact operation, greatly improving the sanitation level and being convenient to use.
