Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bathroom, specifically is a sealing gasket, water drain and drainage device. BACKGROUND

[0002] A drain port is arranged at the bottom of a hand washing basin or a vegetable washing basin, and a water drain is arranged in the drain port to control water drainage and sealing. A traditional water drain, such as CN221461363U (published on August 2, 2024), achieves sealing by the abutment between a sealing ring on the outer side wall of the water drain shell and the inner wall of the drain cylinder of the drain port. This requires the sealing ring to be adapted to the inner wall of the drain cylinder in terms of shape and size. The traditional approach is to provide multiple sealing rings with different diameters for consumers to choose and install, which is not very convenient to use.

[0003] The drain port is formed in a drain cylinder at the bottom of a basin such as a hand washing basin (also known as a face basin). The upper part of the drain cylinder is usually provided with an annular rim. Since the bottom of the face basin has a concave portion, the annular rim installed in the concave portion is usually lower than the surface of the inner cavity of the basin. If a traditional sealing ring is used, the water between the concave portion and the sealing ring is not easy to flow and update, which will cause the concave portion to easily accumulate dirt and odor.

[0004] In view of the above-mentioned defects in the prior art, the present application has been developed. SUMMARY

[0005] The main purpose of the present application is to provide a sealing gasket, a water drain, and a drainage device, which solve the problems of inconvenient use and easy accumulation of dirt and odor of traditional water drains.

[0006] To achieve the above-mentioned purpose, the solution of the present application is as follows:

[0007] A sealing gasket is installed on the upper end cover edge of a water drain shell arranged in the drain port of a face basin. The sealing gasket includes a sealing gasket body in the shape of a hollow ring, which is integrally formed from an elastic material. The sealing gasket body includes a central hole for the water drain shell to pass through, a clamping groove for clamping the upper end cover, and an elastic sealing rim formed on the outer periphery of the sealing gasket body. The clamping groove is located on the upper surface of the sealing gasket body between the central hole and the elastic sealing rim.

[0008] Further, the thickness of the elastic sealing rim gradually decreases from the inside to the outside. In a natural state, the lower surface of the elastic sealing rim is lower on the outside than on the inside.

[0009] Further, the clamping groove is located at the thickest part of the root of the elastic sealing rim.

[0010] Further, the elastic sealing gasket body is formed with a center tube, and the center hole is formed in the middle of the center tube.

[0011] Further, the sealing gasket body is made of rubber or silicone material; the projection of the elastic sealing along the outer edge completely covers the lower recess of the outer periphery of the basin drain.

[0012] A drain, comprising the sealing gasket and a drain housing arranged in the drain port, the drain housing passes through the center hole and is connected with the elastic sealing inside the center hole; the clamping groove of the sealing gasket is connected to the upper end cover edge of the drain housing, and the sealing gasket completely covers the lower surface of the upper end cover; the diameter of the upper end cover edge is greater than the inner diameter of the clamping groove in the natural state without installation.

[0013] Further, the drain housing is provided with a bounce water sealing assembly; the lower part of the drain housing is provided with an odor prevention structure.

[0014] Further, the drain housing is provided with an upper opening, and the upper opening is provided with a filter screen.

[0015] A drain device, comprising a basin and the above-mentioned drain, the bottom of the basin is provided with a lower recess, and the lower recess is provided with a drain port; the drain housing is arranged in the drain port, and the edge of the sealing gasket is in sealing contact with the bottom of the basin.

[0016] Further, the sealing gasket completely covers the lower recess.

[0017] After adopting the above structure, the sealing gasket, the drain and the drain device have at least the following beneficial effects:

[0018] I. The center hole is used for the drain housing to pass through, so that the sealing gasket is aligned with the drain housing and fixed. In addition, the clamping groove is clamped with the upper end cover, so that the elastic sealing along the peripheral part is also fixed; the elastic sealing along the peripheral part is in close contact with the lower recess of the basin body, which reduces the accumulation of sewage in the lower recess and reduces the deposition of odor and stains. When cleaning is needed, the lower recess is connected with the drain housing to be taken out from the drain port of the basin for cleaning. The sealing gasket can also be separated from the drain housing for separate cleaning after the drain housing is taken out, which is very convenient to use.

[0019] II. The thickness of the elastic sealing along the peripheral part gradually decreases from the inside to the outside, so that the elastic sealing along the peripheral part is more easily deformed from the inside to the outside, and the outside is the softest, so that the elastic sealing along the peripheral part can better fit the lower recess; and in the natural state, the lower surface of the elastic sealing along the peripheral part is lower than the inside, so that the elastic sealing along the peripheral part has a downward pressure after deformation.

[0020] III. The lower water device shell can be installed with a flap water sealing component or a bounce water sealing component and other functional water sealing components. The deodorization structure at the bottom of the lower water device shell prevents backflow of the suction.

[0021] IV. The elastic sealing along the outer edge completely covers the lower concave portion of the outer periphery of the basin drain, which can completely cover the lower concave portion and further reduce the possibility of dirt deposition in the lower concave portion.

[0022] Compared with the prior art, the utility model discloses a sealing gasket arranged outside the lower water device shell, which covers the lower concave portion through the sealing gasket, reduces the accumulation of water in the lower concave portion and avoids dirt deposition and odor.
