Description

TECHNICAL FIELD

[0001] The utility model relates to the field of water drainer, especially a water drainer. BACKGROUND

[0002] The Chinese patent document with the publication number CN219710469U discloses a water seal deodorization water drainer, which is characterized in that it comprises a deodorization device main body installed at the drain hole of a washbasin, a water inlet and a drain hole are respectively arranged at the top and one side of the deodorization device main body, a concave platform is arranged inside the deodorization device main body and located at one side of the drain hole; a water baffle is arranged inside the drain hole, a drain hole for draining water is arranged on the upper part of one side of the water baffle, and a water blocking part is arranged on the lower part of the other side of the water baffle, the drain hole is higher than the concave platform, so that the water blocked by the water baffle can overflow the concave platform and block the air flowing from one side of the drain hole to the water inlet.

[0003] In the above-mentioned scheme, when the water drainer is installed, the drain pipe can be connected to the water drainer after penetrating through the washbasin. However, there are various washbasins on the market, and the thicknesses of the washbasins are different. In addition, the dirt blocking baffle at the bottom of the water drainer is fixed on the water drainer. Therefore, when the thickness of the washbasin is relatively small, the drain pipe in the water drainer is likely to be close to or touch the dirt blocking baffle at the bottom of the water drainer, thereby affecting the drainage of the water drainer. SUMMARY

[0004] The utility model aims at providing a water drainer with simple structure and adaptability to washbasins with different thicknesses.

[0005] To achieve the above-mentioned purpose, the utility model adopts the technical scheme as follows:

[0006] A water drainer comprises a main body pipe and a drain pipe, the upper end of the main body pipe is provided with an internal thread, and the drain pipe is connected to the side of the main body pipe and communicates with the main body pipe, characterized in that: it further comprises an end cover used for closing the lower end of the main body pipe, and the end cover is sleeved on the lower section of the main body pipe in a liftable and movable manner.

[0007] There are various washbasins on the market, and the thicknesses of the washbasins with different styles are different. By adopting the above-mentioned technical scheme, when the water drainer is installed, the drain pipe can be connected to the upper end of the main body pipe after penetrating through the washbasin. When a relatively thin washbasin is encountered, the drain pipe may touch or be close to the end cover. The liftable end cover can make the water drainer better adapt to washbasins with different thicknesses when the water drainer is installed, and the flow of water can be made smoother by adjusting the lifting of the end cover.

[0008] The end cover is a pipe body with an open upper end and a closed lower end, the outer periphery of the main body pipe is provided with an annular groove, the upper end of the end cover is provided with a limiting part protruding inward, the limiting part is located in the annular groove, and the annular groove and the limiting part cooperate to limit the stroke of the lifting movement of the end cover.

[0009] By adopting the technical scheme, the annular groove cooperates with the limiting part, which can effectively prevent the end cover from being separated from the main pipe or excessively displaced when subjected to external force.

[0010] The lower end outer circumferential surface of the main pipe is provided with a sealing ring, which is in sealing cooperation with the end cover.

[0011] By adopting the technical scheme, the sealing ring fills the small gap between the outer circumferential surface of the main pipe and the end cover, so that the sealing between the two is more airtight, thereby preventing water from leaking out from the joint between the main pipe and the end cover.

[0012] The end cover comprises a bottom wall and an annular side surface, and the top surface of the bottom wall is provided with a plurality of limiting protrusions arranged at intervals in a circle.

[0013] By adopting the technical scheme, the limiting protrusions can prevent the drainage port of the drain pipe from directly contacting the bottom wall of the end cover when the drain pipe is installed, thereby preventing the drainage from being unsmooth.

[0014] The middle part of the bottom wall is formed with a raised flow guide part, which is small at the top and large at the bottom, and the outer circumferential surface of the flow guide part smoothly transitions with the top surface of the bottom wall.

[0015] By adopting the technical scheme, the middle part of the bottom wall is formed with a raised flow guide part which is small at the top and large at the bottom, which can guide the water flow to flow in all directions, making the water flow more smooth.

[0016] The end cover is made of transparent material.

[0017] By adopting the technical scheme, the end cover made of transparent material can better observe whether the end cover is blocked.

[0018] The caliber of the upper port is smaller than the inner wall of the main pipe, and an inner pipe wall extending downward from the upper port is formed in the main pipe, and the internal thread is formed in the inner pipe wall, and the inner pipe wall is arranged at intervals with the inner wall of the main pipe.

[0019] By adopting the technical scheme, the inner pipe wall extending downward from the upper port is formed in the main pipe, which can better guide and position the installation of the drain pipe, and the internal thread can better cooperate and fix with the drain pipe.

[0020] The lower end of the inner pipe wall is lower than the drain pipe.

[0021] By adopting the technical scheme, water can be accumulated in the main pipe, so as to have the effect of water seal.

[0022] The drain pipe is provided with an odor-proof component.

[0023] By adopting the technical scheme, the odor-proof function can be further increased.

[0024] The drain pipe is provided with a communication opening, and the deodorization assembly comprises a reversible deodorization cover plate, which can close the communication opening and be impacted by water flow to open the communication opening.

[0025] By adopting the above technical scheme, when water flow needs to be drained, the impact force of the water flow can timely open the deodorization cover plate, so that the drainage is not hindered and the smooth drainage is ensured, and after the drainage is completed, the cover plate is automatically returned to the closed position by the self-gravity, and the deodorization effect is continued, so that no additional manual operation is needed, and the use is very convenient.

[0026] The adapter pipe is further provided with a lateral interface at the upper end and a vertical interface at the lower end, and the vertical interface is provided with external threads, and the lateral interface is rotatably sleeved on the drain pipe.

[0027] By adopting the above technical scheme, the lateral interface is rotatably sleeved on the drain pipe, so that the drain pipe can be adjusted to a suitable orientation after installation. BRIEF DESCRIPTION OF DRAWINGS
