Title:
SANITARY FLUSH DEVICE FOR TOILET SEAT LID
Document Type and Number:
WIPO Patent Application WO/2020/154828
Kind Code:
A1
Abstract:
A sanitary flush device for a toilet seat lid, comprising a body (1) having a water passing cavity (11) and a telescopic tube (7) in the body (1). A telescopic tube spring (9) that presses against the telescopic tube (7) to move same is provided in the water passing cavity (11). Two flow channels (71, 72) are provided in the telescopic tube (7) and are connected to a nozzle (3). A valve assembly braked by water pressure is mounted at a water inlet end of the telescopic tube (7). The valve assembly is movably engaged with a control assembly. The control assembly comprises a control ring (5) capable of radially moving along with the body (1). The valve assembly comprises a first valve (61) and a second valve (62) movably fixed to the telescopic tube (7). The two valves (61, 62) respectively movably seal the two flow channels (71, 72). When the water inlet end of the telescopic tube (7) moves to the control ring (5), either of the two valves (61, 62) passes through the control ring (5) and the other valve is pushed against by the control ring (5) such that the flow channel (71, 72) corresponding to the other valve circulates. The device implements sharing the telescopic tube (7) and the nozzle (5) by hip wash and women wash by means of a structure for dual water outlet with a single water inlet pipe, so as to simplify the structure and reduce costs. Quick switching between a flush function and a wash function is implemented by means of the cooperation of the control ring (5) with the first valve (61) and the second valve (62), thereby preventing an overlong flush function and wash function switching time.
