Abstract: A controllable self-cleaning device for a flushing spray nozzle is provided and includes a self-cleaning pole and a manual control valve. The self-cleaning pole is disposed with an inlet and a flushing hole to clean the flushing spray nozzle. The inlet is connected to the flushing hole. The manual control valve is disposed with an inlet port to connect to the water source and a self-cleaning outlet port. The self-cleaning outlet port of the manual control valve is connected to the inlet of the self-cleaning pole. With the above structure, the outflow of the flushing hole of the self-cleaning pole by the manual control valve is manually controllable, so that the user can control the clean time of the self-cleaning pole manually. For a single cool cover, the controllable self-cleaning device includes the self-cleaning pole to clean the flushing spray nozzle.

Abstract: An air suction spray nozzle includes a spray pipe and a nozzle component. A spray pole at the end of the spray pipe is inserted to the nozzle component. The nozzle component includes a spray nozzle housing, a spray nozzle set and a rectifying core. One end of the spray nozzle housing is disposed with an open window. The spray nozzle housing is disposed with flushing holes at the area of the open window. The rectifying core is disposed between the spray pole and the flushing holes. The spray nozzle set is locked and assembled to the open window. Water sprays out of the outlet hole of the rectifying core from the spray pole, and then sprays out of the flushing holes. A vent cavity is disposed between the outlet hole and the flushing holes and is connected to the air through the clearance of the spray nozzle housing and the rectifying core and then through the open window.
