AI Technical Summary

Technical Problem

Existing automatic water tank cleaning devices experience reduced cleaning efficiency and increased power consumption when the filter basket and screen become clogged, and are difficult to detect and address in a timely manner.

Method used

The detection mechanism, consisting of a signal transmitter, reflector, and receiver, detects filter blockage by changing water flow conditions. It uses a movable baffle to switch between the first and second states to block or allow signal transmission. Combined with the processing unit, it determines the filter blockage status and generates an alarm signal.

Benefits of technology

It enables timely detection of filter basket blockage, reduces power consumption, improves cleaning efficiency, simplifies the structure, and reduces product complexity and cost.

Abstract

This disclosure discloses an automatic water tank cleaning device, which may include: a housing having a first water inlet; a filter basket detachably installed inside the housing, the filter basket having a filter screen and a second water inlet, wherein a water inlet channel is formed between the first water inlet and the second water inlet; a signal transmitter configured to transmit a signal to water in the water inlet channel; a signal reflector disposed on the housing on opposite sides of the water inlet channel, configured to reflect the signal from the signal transmitter; and a signal receiver disposed on the housing on the same side of the water inlet channel, configured to receive the signal reflected by the signal reflector; and a processing unit configured to determine the clogging status of the filter screen based on the signal received by the signal receiver.
