Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom technology, specifically relates to an improved sealing gasket, water drainer and drainage device. BACKGROUND

[0002] A drain port is arranged at the bottom of the hand washing basin or vegetable washing basin, and a water drainer is arranged in the drain port to control the drainage and water sealing of the drain port. The traditional water drainer, such as CN221461363U (published on August 2, 2024), realizes sealing by the abutment between the sealing ring sleeved on the outer side wall of the water drainer 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 method is to provide multiple sealing rings with different diameters for consumers to choose and install, which is not convenient to use.

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

[0004] Moreover, due to the inconsistent degree of the concave part of the annular rim at the bottom of the hand washing basin, the problem of adapting the sealing gasket needs to be solved so that the sealing gasket can seal most of the drain ports.

[0005] Therefore, the present application is produced after the inventor of the present application deeply studies the above-mentioned defects in the prior art. CONTENT OF THE UTILITY MODEL

[0006] The main purpose of the utility model is to provide an improved sealing gasket, water drainer and drainage device, which solves the problem of adapting the sealing gasket to the annular rim of the drain cylinder and improves the sealing effect.

[0007] In order to achieve the above-mentioned purpose, the solution of the utility model is as follows:

[0008] An improved sealing gasket is installed on the upper end cover edge of the water drainer shell arranged in the drain port of the face basin, which includes a sealing gasket body in the shape of a hollow ring. The sealing gasket body is integrally formed by an elastic material. The sealing gasket body includes a central cylinder for the water drainer shell to pass through and a first elastic sealing rim formed on the outer periphery of the sealing gasket body. An annular second elastic sealing rim is arranged on the lower surface of the sealing gasket body between the central cylinder and the first elastic sealing rim.

[0009] Further, an arc-shaped part for sealing with the inner ring edge of the annular rim is formed on the outer wall of the central cylinder.

[0010] Further, the maximum thickness of the second elastic sealing edge is less than the minimum thickness of the first elastic sealing edge.

[0011] Further, a clamping groove is formed on the upper surface of the sealing gasket body for clamping with the upper end cover, and the clamping groove is located between the central cylinder and the first elastic sealing edge.

[0012] Further, the thickness of the first elastic sealing edge gradually decreases from the inside to the outside; the thickness of the second elastic sealing edge gradually decreases from the inside to the outside; in the natural state, the height of the lower surface of the first elastic sealing edge is lower on the outside than on the inside; in the natural state, the height of the lower surface of the second elastic sealing edge is lower on the outside than on the inside.

[0013] Further, the sealing gasket body is made of rubber or silicone material; the projection of the outer edge of the first elastic sealing edge completely covers the lower concave part of the outer periphery of the drain port; and the second elastic sealing edge abuts against the upper surface of the annular edge of the drain cylinder.

[0014] A drain includes the sealing gasket and a drain housing which is arranged in the drain port and through the central cylinder and is elastically connected with the inside of the central cylinder; the sealing gasket is elastically clamped to the edge of the upper end cover of the drain housing, and the sealing gasket completely covers the lower surface of the upper end cover.

[0015] Further, a bounce water sealing assembly is installed in the drain housing; and a deodorization structure is installed at the lower part of the drain housing.

[0016] A drain device includes a washbasin and the above-mentioned drain, the bottom of the washbasin is provided with a lower concave part, the lower concave part is provided with a drain cylinder, the top of the drain cylinder is provided with an annular edge, the middle of the annular edge is a drain port, the drain housing is arranged in the drain port, the sealing gasket completely covers the lower concave part, the edge of the first elastic sealing edge of the sealing gasket is in sealing contact with the bottom of the washbasin, and the edge of the second elastic sealing edge is in sealing contact with the annular edge.

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

[0018] I. The central cylinder is used for the drain housing to pass through, so that the sealing gasket is aligned with and fixed to the drain housing. The first elastic sealing edge is in contact with the lower concave part of the basin body, and the second elastic sealing edge is in sealing contact with the annular edge. In this way, at least one of the first elastic sealing edge and the second elastic sealing edge can be sealed, and the sealing effect is ensured.

[0019] A negative pressure cavity can be further formed between the first elastic sealing edge and the second elastic sealing edge, so that the sealing gasket is firmly fixed to the drain port.

[0020] II. The thickness of the first elastic sealing edge gradually decreases from the inside to the outside, so that the elastic sealing edge is easier to deform from the inside to the outside, and the outside is the softest, so that the first elastic sealing edge can better fit the concave part; the second elastic sealing edge also gradually decreases in thickness from the inside to the outside, so that the second elastic sealing edge can be sealed with the upper surface of the annular edge.

[0021] And in the natural state, the height of the lower surface of the first elastic sealing edge and the second elastic sealing edge is lower than the inside, so that the first elastic sealing edge, the outer periphery and the outer periphery of the second elastic sealing edge have a downward pressure.

[0022] Compared with the prior art, the utility model discloses a first elastic sealing edge and a second elastic sealing edge are arranged on the sealing gasket, and the two elastic sealing edges cooperate with each other, so that the adaptability of the sealing gasket is improved.

Detailed Implementation

[0034] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0035] like Figures 1 to 3 As shown, this is an improved sealing gasket 10 according to the present invention, which is installed on the edge of the upper end cover 21 of the drain housing 2 of the drain outlet 31 of the basin 3. It includes a sealing gasket body 1 with an annular hollow shape, which is integrally formed of elastic material. The sealing gasket body 1 includes a central cylinder 12 through which the drain housing 2 passes and a first elastic sealing edge 14 formed on the outer periphery of the sealing gasket body 1. An annular second elastic sealing edge 11 is provided on the lower surface of the sealing gasket body 1 between the central cylinder 12 and the first elastic sealing edge 14.

[0036] Thus, in this improved sealing gasket 10, drain assembly 20, and drainage device 30, the central cylinder 12 allows the drain assembly housing 2 to pass through, thereby aligning and fixing the sealing gasket 10 to the drain assembly housing 2. The first elastic sealing edge 14 fits against the recessed portion 32 of the basin, and the second elastic sealing edge 11 seals against the annular edge 34. This ensures that at least one of the first elastic sealing edge 14 and the second elastic sealing edge 11 can seal, guaranteeing a sealing effect. A negative pressure cavity can also be formed between the first elastic sealing edge 14 and the second elastic sealing edge 11, firmly fixing the sealing gasket 10 to the drain outlet 31.

[0037] Preferably, the upper end of the outer wall of the central cylinder 12 is formed with an arc-shaped portion 121 for sealing with the inner edge of the annular edge 34. The arc-shaped portion 121 can abut against the inner edge of the annular edge 34 to form a seal. In this way, a vacuum cavity can be formed between the inner edge of the annular edge 34 and the second elastic sealing edge 11, or a large vacuum cavity can be formed between the inner edge of the annular edge 34 and the first elastic sealing edge 14. This allows the sealing gasket 10 to adhere to the drain outlet 31 of the basin 3.

[0038] Preferably, the maximum thickness of the second elastic sealing edge 11 is less than the minimum thickness of the first elastic sealing edge 11. This makes the elasticity of the second elastic sealing edge 11 weaker than that of the first elastic sealing edge 11, thus preventing the second elastic sealing edge 11 from lifting the sealing gasket 10 and affecting the sealing effect of the first elastic sealing edge 11.

[0039] Further, the upper surface of the sealing gasket body 1 is formed with a clamping groove 13 for clamping with the upper end cover 21. The clamping groove 13 is located between the central cylinder 12 and the first elastic sealing edge 14. The sealing gasket body 1 is sealed with the upper end cover 21 through the clamping groove 13.

[0040] Preferably, the thickness of the first elastic sealing edge 14 gradually decreases from the inside to the outside; the thickness of the second elastic sealing edge 11 gradually decreases from the inside to the outside; in the natural state, the height of the lower surface of the first elastic sealing edge 14 is lower on the outside than on the inside; in the natural state, the height of the lower surface of the second elastic sealing edge 11 is lower on the outside than on the inside.

[0041] The thickness of the first elastic sealing edge 14 gradually decreases from the inside to the outside, so that the elastic sealing edge deforms more easily from the inside to the outside, and the outside is the softest, so that the first elastic sealing edge 14 can better fit the lower recess 32; the second elastic sealing edge 11 also gradually decreases in thickness from the inside to the outside, so that the second elastic sealing edge 11 can fit and seal with the upper surface of the annular edge 34. And in the natural state, the height of the lower surface of the first elastic sealing edge 14 and the second elastic sealing edge 11 is lower on the outside than on the inside, so that after the elastic sealing edge deforms, the first elastic sealing edge 14 and the outer periphery of the second elastic sealing edge 11 have a downward pressure.

[0042] Preferably, the sealing gasket body 1 is made of rubber or silicone material; the projection of the outer edge of the first elastic sealing edge 14 completely covers the lower recess 32 of the outer periphery of the drain 31 of the washbasin 3; the second elastic sealing edge 11 abuts against the upper surface of the annular edge 34 of the drain cylinder 33.

[0043] The utility model also provides a kind of drain 20, as shown in Figure 4 The utility model also provides a kind of drain 20, as shown in Figure 8 And Figure 9 Preferably, as shown in

[0044] The utility model also provides a kind of drain 20, as shown in Figure 6 And Figure 7As shown, including face basin 3 and the above-mentioned drain 20, the bottom of the basin 3 is provided with a lower recess 32, the lower recess 32 is provided with a drain cylinder 33, the top of the drain cylinder 33 has a ring-shaped along 34 (such as Figure 5 The ring-shaped along 34 is in the middle of the drain 31; the drain housing 2 is installed in the drain 31, the sealing gasket 10 completely covers the lower recess 32, the edge of the first elastic sealing edge 14 of the sealing gasket 10 is in sealing contact with the bottom of the basin 3; the edge of the second elastic sealing edge 11 is in sealing contact with the ring-shaped along 34.
