[0020] The present invention will be further described below with reference to the accompanying drawings. Figure 1-3 :
[0021] A flushing water tank 1 of a wall-mounted toilet, the flushing water tank 1 is an L-shaped structure, including a horizontal section extending forward and a vertical section extending upward, the horizontal section extends into a cavity between the bottom of a basin body 2 and an outer shell 3, and the vertical section extends into a cavity between the rear side of the basin body 2 and the outer shell 3, a water inlet interface 4 connected to a water supply device is provided at the bottom of the rear end of the horizontal section, and a water outlet interface 5 connected to a water pump inlet pipe is provided at the front end, a water inlet valve 6 connected to the water inlet interface 4 is provided in the flushing water tank 1, an overflow port 7 is provided on one side of the upper end of the vertical section, and the upper end of the water inlet valve 6 exceeds the overflow port 7. During installation, the horizontal section of the flushing tank 1 is inserted obliquely into the cavity between the bottom of the basin body 2 and the outer shell 3, and is rotated downward during the insertion process and finally installed to the predetermined position. Since the flushing tank 1 utilizes the original gap between the basin body 2 and the outer shell 3, there is no need to add too much additional space. The structure combining the horizontal section and the vertical section of the flushing tank 1 can also ensure that the flushing tank 1 has a sufficiently large water storage capacity.
[0022] Furthermore, a base 8 is provided on the upper end surface of the rear side of the housing 3 , and the base 8 is covered on the flushing tank 1 . This embodiment uses the base 8 as a cover plate of the flushing tank 1 , thereby simplifying the structure of the flushing tank 1 .

The mounting ear 13 is used to fix the flushing water tank 1, the supporting sheet 14 provides sufficient hanging support force for the flushing water tank 1, and the gasket provides sufficient shelf support force for the flushing water tank 1. By adjusting the height of the gasket, the flushing water tank 1 can also be adapted to shells 3 of different specifications.
[0026] In order to better guide the overflow water, the overflow port 7 is arranged at the top front side of the flushing water tank 1, and the overflow port 7 extends forward to form a guide groove 15. Further, the guide groove 15 is surrounded by a bottom plate and side plates on both sides.
[0027] In order to facilitate production and mold opening, the flushing water tank 1 is a split structure, including a water tank upper part 16 and a water tank lower part 17. The water tank upper part 16 and the water tank lower part 17 are welded and fixed. The joining plane of the water tank upper part 16 and the water tank lower part 17 is a horizontal plane and is located in the middle of the horizontal section.
[0028] The water outlet interface 5 is connected to the water pump through the water pump inlet pipe, and the water pump outlet is connected to the distribution valve, and the distribution valve is connected to the skirt flushing port and the bottom flushing port respectively. When in use, the flushing method can be adjusted according to actual needs, for example, flushing from top to bottom through the skirt flushing port first, and then flushing through the bottom flushing port.
