Description

Microwave induction automatic flushing device for toilet bowl Technical Field The invention relates to the technical field of toilets, in particular to an induction automatic flushing device of a toilet. Background The induction flushing device for the closestool is used for judging whether a person uses the current closestool or not by collecting the change of a motion signal after the person gets up from the closestool and leaves the closestool or the movement condition of the person when urine enters the closestool when the person stands at the side of the closestool and controlling the flushing valve to flush according to the judging result so as to meet the flushing requirement of the user. When the induction flushing device is used, a user can flush without pressing a drainage key of the closestool, so that the probability of forgetting to flush after the user finishes the toilet is reduced, and the problem of cross infection caused by grasping a drainage handle by personnel can be avoided especially when the induction flushing device is used for the closestool in public places. At present, in public toilets and home environments, a large number of traditional common toilets are still used, when the toilets are required to be upgraded and modified to achieve induction flushing, the old toilets are required to be detached integrally, new toilets are required to be replaced, the replacement workload of the toilets is large, the replaced toilets are generally abandoned, and the cost of the upgrade and modification of the induction flushing of users is increased.
