[0002] Currently, prefabricated bathroom fixtures are widely used. The waterproof base of prefabricated bathroom fixtures is a single, integral structure. The thickness of the base, along with the drain and pipe fittings, is relatively large, resulting in noticeable steps after installation. This fails to meet the market demand for barrier-free installations. Furthermore, current side-drain drains on the market are too simple, lacking water seal odor prevention and having poor filtration. In short, prefabricated bathroom fixtures currently struggle to meet market demands in terms of side drainage or low-finish surfaces.

[0003] Its thickness is small and its dimensions are compact in the height direction. The wall-mounted floor drain that matches the waterproof base also needs to be compact in structure, easy to install and flexible in use. Current wall-mounted floor drains are difficult to meet the requirements. Utility Model Content

[0028] To better understand the technical solutions of the embodiments of this utility model, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] like Figures 1 to 6 As shown in the figure, this utility model embodiment discloses a wall-mounted floor drain 100. The wall-mounted floor drain 100 is used in the waterproof base 5 of a prefabricated bathroom. The wall-mounted floor drain 100 includes a water collection box 1, a perforated partition 2, and a drain connector 3.

[0031] The water collection box 1 is a long, narrow box structure with an open top. Inside the water collection box 1, there is a partition wall 10 extending along its length. The top of the partition wall 10 is lower than the top of the water collection box 1. The partition wall 10 divides the water collection box 1 into a first water tank 11 and a second water tank 12. The side wall of the second water tank 12 has a connecting pipe 13 extending horizontally. In use, the water collected by the waterproof base 5 first enters the first water tank 11, then overflows the partition wall 10, and then enters the second water tank 12, flowing out of the second water tank 12 through the connecting pipe 13 on its side wall.

[0032] The perforated partition 2 is positioned above the water collection box 1, and its overall structure is a long, narrow plate. For example... Figure 4 As shown, the perforated partition 2 has a top plate portion 21 and a vertical plate portion 22. The vertical plate portion 22 is disposed approximately vertically on the surface of the top plate portion 21. Several triangular ribs 24 are provided between the vertical plate portion 22 and the top plate portion 21 to increase the structural strength of both. The vertical plate portion 22 is disposed along the length direction of the water collection box 1 and extends from top to bottom into the first water tank 11.

[0033] The vertical plate 22 and the inner wall of the first water tank 11 form a water trap. In this embodiment, the first water tank 11 has vertical ribs 15 at both ends. When the vertical plate 22 is inserted into the first water tank 11, both ends of the vertical plate 22 will respectively come into close contact with one of the vertical ribs 15, forming a seal. Since the bottom of the vertical plate 22 does not contact the bottom wall of the first water tank 11, a channel for water to pass through is formed between the bottom surface of the vertical plate 22 and the bottom wall of the first water tank 11, thus forming a water trap structure.

[0034] The top plate 21 covers the upper part of the water collection box 1, and the top plate 21 is provided with a plurality of through holes 23 communicating with the side of the return water bend away from the partition wall 10. That is to say, all of these through holes 23 are located on the side of the vertical plate 22 away from the partition wall 10.

[0035] In use, water flows from the upper surface of the perforated partition 2 through the through hole 23 into one side of the return water bend of the first water tank 11.

[0036] like Figure 5 As shown, the drain connector 3 includes a water pipe connection part 31 and a plug pipe 32. The plug pipe 32 is plugged into and sealed to the connecting pipe 13 of the water collection box 1. The ports of the plug pipe 32 and the connecting pipe 13 are mutually matched, and corresponding snap-fit ​​structures can be set between them to achieve plugging. The plug pipe 32 and the connecting pipe 13 can be sealed with various sealing materials such as sealant, sealing rings, and waterproof tape.

[0037] The water pipe connector 31 is a component that connects to the drainage pipe 6 to discharge water into the sewer. The water pipe connector 31 includes a circular pipe structure 311 and an end cap 312. Each end of the circular pipe structure 311 has a port, both of which can be used to connect to the drainage pipe 6. The end cap 312 is detachably connected to one port of the circular pipe structure 311. When the end cap 312 seals one end of the circular pipe structure 311, the other port can be used to connect to the drainage pipe. In use, one port of the circular pipe structure 311 can be sealed according to site requirements.

[0038] As can be seen from the above description, the wall drain 100 of this embodiment has a water collection box 1 and a drain connector 3 arranged horizontally. The water collection box 1 is a long and narrow box. A first water tank and a second water tank are set in the water collection box 1, and a water return bend is formed to form a water seal, which effectively isolates odors and pests. The overall structure is compact, uses fewer parts, has a relatively simple structure, is easy to install, and is flexible in use.

[0039] Furthermore, the wall-mounted floor drain 100 also includes a water inlet cover plate 4, which is a flat plate component located above the perforated partition plate 2. A long, narrow water inlet slit 41 is provided in the center of the water inlet cover plate 4 to guide water through the through-hole 23 of the perforated partition plate 2. This water inlet slit 41 can be a sloping structure, which can better guide the direction of water flow and improve drainage efficiency.

[0040] In this embodiment, the connecting pipe 13 on the side wall of the second water tank 12 and the insertion pipe 32 of the drain connector 3 are both square tube structures. Using a square tube structure can effectively reduce the height of the pipes while ensuring drainage capacity, facilitating layout.

[0041] like Figure 5 As shown, furthermore, the central axis of the insertion pipe 32 of the drain connector 3 is not coincident with the axis of the circular pipe structure of the water pipe connection 31, allowing the insertion pipe 32 to be inserted into the connecting pipe either correctly or incorrectly. Figure 1 The image shows the insertion pipe 32 in the correct position. If the drain connector 3 is pulled out, rotated 180 degrees, and then reinserted into the insertion pipe 32, the insertion pipe 32 will be in the reverse position. By changing the state of the insertion pipe 32, the height of the axis of the circular pipe structure 311 can be changed, thus adapting to different drainage methods and offering flexible use.

[0042] like Figure 2 and Figure 3 As shown, the partition wall 10 has a water guide slope 101 inclined towards the first water tank 11 in the middle. This water guide slope 101 can guide the horizontal water flow from the first water tank 11 to the second water tank 12.

[0043] Multiple water-blocking strips 14 are spaced apart on the side wall where the second water tank 12 connects to the connecting pipe 13. These water-blocking strips 14 can block hair and other debris in the second water tank 12, thereby preventing the pipe from being blocked by hair. The water-blocking strips 14 and the through holes 23 on the perforated partition 2 form a double-layer filter, which prevents pipe blockage and is easy to clean.

[0044] In this embodiment, the water collection box 1, the perforated partition 2, and the drain connector 3 are made of plastic. In other embodiments of this utility model, stainless steel or other materials can also be used. This wall-mounted floor drain can be used in conjunction with the waterproof base of prefabricated bathroom fixtures, effectively reducing the structural thickness.

[0045] This utility model embodiment also discloses a waterproof chassis for a prefabricated bathroom, including a chassis body and the aforementioned wall-mounted floor drain, which is installed on one side of the chassis body.

[0046] This utility model embodiment also discloses a prefabricated bathroom fixture, including a waterproof chassis. The waterproof chassis includes a chassis body and the aforementioned wall-mounted floor drain, which is installed on one side of the chassis body.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
