[0041] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0042] like Figures 1-3 As shown, this embodiment provides a wall-hung toilet, including: a water tank 100 and a water pump 200 connected to the water tank 100. A detachable filter device 300 is provided at the connection between the water tank 100 and the water pump 200. It is understood that the filter device 300 can be any existing filtration structure or device, such as a screen filter, adsorption filter, or membrane filter. Detachable installation methods include threaded connection, flange connection, and plug-in connection. The filter device 300 can effectively intercept larger particles of impurities such as sediment and rust in the water, preventing these impurities from entering the water pump 200 and protecting the water pump 200. Simultaneously, the filter device 300 adopts a detachable installation design; when the filter device 300 accumulates a large amount of impurities affecting the filtration effect, the user can easily remove it from the connection between the water tank 100 and the water pump 200 for cleaning or replacement. In this embodiment, the filter device 300 is located near point a, and the filter device 300 uses a cylindrical filter screen.

[0043] In some embodiments, such as Figures 2-3 As shown, the filter device 300 is fixed to the inlet of the water pump 200 and / or the water tank 100 by fasteners or snap-fit ​​connections. It is understood that the fasteners can be bolts, nuts, screws, etc. Using fasteners for the filter device 300 provides good connection strength and stability, and has a wide range of applications. Using snap-fit ​​connections for the filter device 300 provides better shock resistance, better resistance to vibrations generated during flushing, and a longer service life.

[0044] In some embodiments, such as Figures 2-5As shown, it also includes a water suction cover 400, which can be detachably installed on the water tank 100, or the water suction cover 400 can be integrated with the water tank 100. The water suction cover 400 has a water intake 410 facing the bottom of the water tank 100, and the water in the water tank 100 is drawn out by the water pump 200 through the water intake 410. It can be understood that the inlet and outlet of the L-shaped water suction cover 400 are the water intake 410 and the water outlet 420, respectively. When water flows from the water tank 100 to the water intake 410 of the water suction cover 400, the water suction cover 400 can guide the water flow out from the water outlet 420. Specifically, the suction hood 400 is detachably mounted on the water tank outlet 420. The suction port 410 of the suction hood 400 faces the bottom of the water tank 100. The suction hood 400 connects the water tank 100 and the water pump 200. The water pump 200 draws the cleaning water in the water tank 100 from the suction port 410 of the suction hood 400 towards the water pump 200. It can be understood that the installation of the suction hood 400 can reduce the remaining water level in the water tank 100, allowing for a smaller water tank while supplying sufficient cleaning water to the toilet, thus improving the utilization rate of the water in the water tank 100. It should be noted that the remaining water level in the water tank 100 refers to the water level in the water tank 100 when the water pump 200 cannot remove the water during continuous pumping.

[0045] In some embodiments, such as Figures 5-6 As shown, the water suction hood 400 includes a horizontal section 411 and a vertical section 412, which intersect in an L-shape. The horizontal section 411 is provided with a water suction port 410, which has a water suction gap with the bottom of the water tank 100. The vertical section 412 is provided with a water outlet 420 facing the water pump 200. It can be understood that the water suction gap means that the water suction port 410 is not tightly attached to the bottom of the water tank 100, but has a certain gap, which facilitates the flow of water.

[0046] In some embodiments, such as Figure 3 As shown, the water absorption cover 400 is fitted around the outer circumference / inner ring of the cylindrical filter device 300. The water absorption cover 400 and the filter device 300 can be designed as an integral part or as separate parts. It is understandable that when the water absorption cover 400 and the filter device 300 are designed as an integral part, the overall appearance is more cohesive and the visual effect is more upscale. When the water absorption cover 400 and the filter device 300 are designed as separate parts, each component can be optimized independently, making manufacturing and maintenance easier.

[0047] In some embodiments, such as Figures 6-8As shown, the filter device 300 includes an outer peripheral wall 310, with a first end face 320 connected to one side of the outer peripheral wall 310. The outer peripheral wall 310 and the first end face 320 are provided with a plurality of filter holes. The first end face 320 is positioned facing the water inlet 410. The filter device 300 has an opening on the side away from the first end face 320 and a radially protruding edge 330. The edge 330 abuts against the water outlet 420 of the water suction hood 400 or the water tank 100. The outer peripheral wall 310 is axially provided with a rib 340, which abuts against the inner wall of the water suction hood 400 or the water tank 100. It can be understood that the function of the first end face 320 facing the water inlet 410 is that when the water pump 200 draws water, the water entering from the water inlet 410 can flow directly through the first end face 320, allowing the filter holes on the first end face 320 to fully perform their filtering function. Therefore, the first end face 320 can be partially or entirely facing the water inlet 410.

[0048] In some embodiments, such as Figure 2 , Figures 9-10 As shown, the water tank 100 includes a first tank 110, a second tank 120, and a balancing tank 130. The balancing tank 130 connects the first tank 110 and the second tank 120. The balancing tank 130 has an outlet pipe 131 on its side wall. A water pump 200 is connected to the outlet pipe 131 and installed on top of the balancing tank 130. A filter device 300 and / or a suction hood 400 are inserted into the outlet pipe 131. It is understood that the first tank 110 and the second tank 120 are located below the toilet bowl. Connecting the first tank 110 and the second tank 120 with the balancing tank 130 increases the water tank capacity. In this embodiment, the outer shells of the first tank 110, the second tank 120, and the balancing tank 130 are joined end-to-end to form a ring structure.

[0049] In some embodiments, such as Figure 9 As shown, the water absorption cover 400 is provided with a locking block 430, and the water outlet pipe 131 is provided with a notch 132. The water absorption cover 400 is installed by locking the locking block 430 into the notch 132. In this embodiment, the locking block 430 is provided on the periphery of the water outlet 420 of the water absorption cover 400, and there can be one or more of them. During assembly, the water absorption cover 400 is first inserted into the water outlet pipe 131, and the locking block 430 of the water absorption cover 400 is locked into the notch 132 of the water outlet pipe 131. Then, the filter device 300 is installed into the water absorption cover 400.

[0050] In some embodiments, such as Figure 2 As shown, it also includes a connecting pipe 500, which connects the water outlet pipe 131 and the inlet of the water pump 200; the connecting pipe 500 is locked onto the water outlet pipe 131 by a clamp.

[0051] In some embodiments, such as Figures 1-2 , Figures 9-10As shown, the wall-hung toilet includes a bowl with a bowl-shaped surface, a first tank 110 located behind and / or below the bowl, a second tank 120 located behind and / or below the bowl, and a balancing tank 130 located behind and / or below the bowl.
