Document Type and Number:
WIPO Patent Application WO/2021/238160
Kind Code:
A1
Abstract:
Disclosed is a hand washing machine capable of automatically adjusting a sensing height, the machine comprising: a containing portion (110), a nozzle (210), a pump (500), a controller (600), a distance sensor (400), a first trigger portion (310), and a second trigger portion (320), wherein the controller (600) is configured to: receive first signals continuously sent by the first trigger portion (310) and receive a second signal instantaneously sent by the second trigger portion (320), and record a distance value currently sent by the distance sensor (400) as a pump starting distance; and when the received distance value sent by the distance sensor (400) is equal to the pump starting distance, send a working signal to the pump (500). The hand washing machine is simple in terms of structure, is convenient to use, and can be set with different pump starting distances to trigger the hand washing machine to spray liquid at different sensing heights, such that the hand washing machine can meet requirements for height in different scenarios.
