Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a toilet bowl 5, sink water tank 1, locate the water intaking valve 2 and the overflow subassembly that sink in the water tank 1, the overflow subassembly includes water tank overflow pipe 3, overflow pipeline 4 and goes out water end 6, and wherein, water tank overflow pipe 3 locates the upper portion in the water tank 1 that sinks relatively, and when the water level risees, water can pass through water tank overflow pipe 3, overflows to toilet water seal the inside through overflow pipeline 4, it is linked together with toilet bowl 5 to go out water end 6, and it includes jet 9 and overflow delivery port to go out water end 6, water

tank overflow pipe
