SELF-CLEANING DEVICE AND A SELF-CLEANING METHOD FOR AN ELECTROLESS SHOWER-WC ATTACHMENT

摘要

The invention discloses a self-cleaning device for a non-electric flushing cover plate. The self-cleaning device comprises a main body and a cleaning water path, a water flow channel is formed in themain body, the cleaning water path is communicated with the water inlet end of the water flow channel, when a telescopic water outlet pipe is located at the initial position, the water outlet end of the water flow channel is located over the front end of the telescopic water outlet pipe, a one-way valve is arranged at the position, at the water inlet end, of the water flow channel, and water flowof the cleaning waterway can rush through the one-way valve to supply water to the water flow channel. The self-cleaning device also comprises a pressing block arranged at the rear end of the telescopic water outlet pipe, and the pressing block abuts against the one-way valve when the telescopic water outlet pipe moves to the water outlet position so as to close the water inlet end of the water flow channel. As the pressing block can abut against the one-way valve when the telescopic water outlet pipe moves to the water outlet position, once the telescopic water outlet pipe reaches the water outlet position, the one-way valve can close the cleaning waterway, and the water outlet end of the water flow channel does not discharge water any more.
