Description

A pressure-sensitive toilet appliance

technical field

The utility model relates to a toilet appliance, in particular to a pressure-sensitive toilet appliance.

Background technique

At present, the flushing system of the bathroom often uses infrared rays as the control signal. When someone is close to the infrared sensor, the infrared sensor receives the infrared rays emitted by the human body, and the control switch automatically connects the load, thereby realizing the function of automatic flushing. However, the infrared sensor is susceptible to external interference. For example, when someone passes by the infrared sensor, the infrared sensor will malfunction, resulting in unnecessary waste of water.
