PUSH-TYPE DRIVING DEVICE FOR TOILET DRAIN VALVE, AND AUTOMATIC FLUSHING UNIT

WIPO Patent Application WO/2024/037108

A1

Disclosed in the present utility model are a push-type driving device for a toilet drain valve, and an automatic flushing unit. The push-type driving device for the toilet drain valve drives a pushing member to move in a height direction by means of a driving component and links a drain plug to open a valve port. A fixed member is fixedly arranged at an end of the toilet drain valve, and the pushing member is arranged in a cavity of the fixed member, the drain plug is linked to open the valve port by means of the movement of the pushing member in the height direction for flushing. By using this structure, a user only needs to control the driving component for flushing, so that a user's use process is simplified, compared with the prior art in which a mechanical key is operated by a user for flushing. In comparison with a tedious driving device, this structure controls the drain valve by using fewer parts, so that a mounting space occupied by the driving device is reduced, thereby facilitating the mounting of such a push-type driving device in a smaller water tank.
