Description

Technical Field

[0001] This utility model relates to the field of water tank technology, and in particular to a drain device and water tank structure. Background Technology

[0002] A sink drain is a device used to control the drainage of a sink. Traditional sink drains are mostly installed at the bottom of the sink and use relatively simple structures such as rubber rings to seal the gaps. However, if the rubber rings fail, these drains are prone to leakage, allowing sewage to enter between the outer shell and the inner tank, causing dirt accumulation and odor. Chinese patent CN222413274U discloses a sink and an integrated structure with the sink. The drain is located at the rear bottom of the sink, and a first sealing element combined with a screw connection structure seals the gap near the opening between the inner tank and the outer shell, reducing leakage and odor to some extent. However, in this solution, the sealing element is only placed in the gap near the opening between the inner tank and the outer shell. To avoid siphoning and water accumulation in the gap between the inner tank and the bottom of the outer shell, the distance between the inner tank and the bottom of the outer shell must be increased. This increases the size of the drain, occupies a large space at the bottom of the sink, and reduces the overall integrity of the drain. Therefore, there is an urgent need for a drain and sink structure that occupies less space, has a stronger overall integrity, and can prevent the accumulation of dirt and odor in the aforementioned gaps. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this utility model is to provide a drainer and sink structure to solve the problems existing in the prior art, so that the drainer can prevent the accumulation of dirt and odor while taking up less space and having a stronger overall structure.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example 1

[0031] This embodiment provides a drain device, such as... Figure 1-9 As shown, it includes: an outer shell 1 and an inner liner 2, both having openings. The inner liner 2 is at least partially disposed inside the outer shell 1. There is a main body gap 4 between the inner wall of the outer shell 1 and the outer wall of the inner liner 2. At least at both ends of the main body gap 4, blocking elements are respectively provided to prevent liquid from entering the main body gap 4.

[0032] The drainer provided in this embodiment improves the sealing performance between the inner tank 2 and the outer shell 1 by setting blocking elements at least at both ends of the main body gap 4. Compared with setting a sealing element only at one end of the gap between the outer shell 1 and the inner tank 2, sealing both ends of the main body gap 4 with blocking elements avoids the accumulation of sewage caused by the siphon effect due to the small gap design between the inner tank 2 and the outer shell 1, thereby reducing the space occupied by the drainer under the water tank structure and improving the overall integrity of the water tank structure.

[0033] It should be noted that in the above embodiments, the inner liner 2 can be entirely set inside the outer shell 1 as needed, or it can be partially set inside the outer shell 1; the blocking members need to be set at least at both ends of the main body gap 4. Of course, while setting sealing members at both ends of the main body gap 4, multiple blocking members can be set sequentially in the middle of the main body gap 4 to increase the sealing performance.

[0034] In this embodiment, the bottom of the outer shell 1 is provided with a drain outlet communicating with a pipe, and the bottom of the inner liner 2 is provided with a drain outlet 21. The drain outlet 21 communicates with the drain outlet. The end of the main body gap 4 near the drain outlet 21 is a first gap 41, which extends circumferentially along the drain outlet 21. The blocking member near the drain outlet 21 is a first blocking member 5, which is disposed within the first gap 41 and extends along the first gap 41. The two sides of the first blocking member 5 are respectively attached to the outer wall of the inner liner 2 and the inner wall of the outer shell 1. By setting the first blocking member 5 within the first gap 41 and making the two sides of the first blocking member 5 respectively attached to the outer wall of the inner liner 2 and the inner wall of the outer shell 1, the sealing performance is further improved. In use, sewage enters the space formed by the outer shell 1 and the inner liner 2 from the drain outlet 21 and is discharged from the drain outlet. The above design can prevent the problem of some sewage entering the main body gap 4 and failing to enter the drain outlet due to siphon effect when the main body gap 4 is set too small.

[0035] To facilitate the disassembly and assembly of the inner liner 2, the first blocking member 5, and the outer shell 1, in this embodiment, the drainer provided in this embodiment further includes: mounting screws 8, the outer shell 1 is provided with a first screw hole, the inner liner 2 is provided with a second screw hole, and the first blocking member 5 is provided with a connecting through hole. The positions of the first screw hole, the connecting through hole, and the second screw hole correspond one-to-one, and the mounting screws 8 can be simultaneously inserted into the first screw hole, the connecting through hole, and the second screw hole.

[0036] Specifically, the number of the first screw hole, the second screw hole, and the connecting through hole is not limited and can be set as needed. In this case, a washer can be placed between the nut of the mounting screw 8 and the first screw hole to increase the contact area, improve friction, and prevent misalignment along the circumference of the mounting screw 8 between the inner liner 2, the outer shell 1, and the first blocking member 5. Preferably, in order to improve the reliability of the connection, two of each of the first screw hole, the second screw hole, and the connecting through hole are provided, and two mounting screws 8 are also provided. Example 2

[0037] This embodiment provides a water tank structure, including a basin 3 and a drain device as described in Embodiment 1, with the drain device located at the rear bottom of the basin 3.

[0038] The water tank structure provided in this embodiment uses the drain device from Embodiment 1.

[0039] In this embodiment, the bottom of the trough 3 has an inner opening 31 that connects the inner and outer sides of the trough 3. The outer shell 1 is partially disposed outside the trough 3, and the outer shell 1 corresponds to the position of the inner opening 31. Part of the inner liner 2 passes through the inner opening 31 from inside the trough 3 and is disposed inside the outer shell 1. The outer shell 1, the trough 3 and the inner liner 2 are connected.

[0040] Furthermore, such as Figure 7-9As shown, the end of the main body gap 4 near the opening of the inner liner 2 is the second gap 42. The blocking components near the opening of the inner liner 2 include a second blocking component 6 and a third blocking component 7. There is an outer gap 421 between the outer wall of the inner liner 2 and the inner wall of the basin 3, and an inner gap 422 between the inner wall of the outer shell 1 and the outer wall of the basin 3. The inner gap 422 and the outer gap 421 form the second gap 42. The second blocking component 6 is disposed in the outer gap 421, with both sides of the second blocking component 6 contacting both sides of the outer gap 421. The third blocking component 7 is disposed in the inner gap 422, with both sides of the third blocking component 7 contacting both sides of the inner gap 422. By using a nested assembly of the inner liner 2, basin 3, and outer shell 1, and by sealing the inner gap 422 and the outer gap 421 with the second and third sealing components respectively, the sealing performance is further improved, and the risk of leakage is reduced.

[0041] It should be noted that in the above embodiments, the inner gap 422 and the outer gap 421 are both formed by the nested design of the inner liner 2, the trough 3 and the outer shell 1. However, if the inner liner 2 is only placed inside the outer shell 1, and the integral structure formed by the inner liner 2 and the outer shell 1 is directly installed at the bottom of the trough 3, the second gap 42 becomes the gap between the inner wall of the outer shell 1 and the outer wall of the inner liner 2. At this time, only a blocking member needs to be set at this end.

[0042] In this first embodiment, the opening of the outer casing 1 has a groove 11 extending circumferentially along the opening of the outer casing 1, and the third blocking member 7 is disposed in the groove 11. The groove 11 can effectively limit the third blocking member 7 and prevent the third blocking member 7 from falling off.

[0043] In this first embodiment, the first blocking member 5, the third blocking member 7, and the second blocking member 6 are all made of soft material. Soft material blocking members can be deformed under pressure and effectively seal gaps. The blocking members can be made of materials such as silicone or rubber.

[0044] In this first embodiment, both the second blocking member 6 and the third blocking member 7 include a central portion 71 and a toothed portion 72. The toothed portion 72 is fixedly connected to the outer periphery of the central portion 71. The toothed portion 72 of the third blocking member 7 contacts the inner side of the outer shell 1 and the outer side of the trough 3, respectively. The toothed portion 72 of the second blocking member 6 contacts the outer side of the inner liner 2 and the inner side of the trough 3, respectively. The tip or edge of the toothed portion 72 will generate higher local contact pressure when compressed, thereby more effectively pressing the second blocking member 6 and the third blocking member 7, filling the inner gap 422 and the outer gap 421, and optimizing the sealing effect.

[0045] It should also be noted that the position, shape and number of the three blocking members are not limited for the first blocking member 5 in Embodiment 1 and the second blocking member 6 and the third blocking member 7 in this embodiment. For example, the first blocking member 5 can be set outside the first gap 41 but cover the outward opening of the first gap 41, which can also play a sealing role; the first blocking member 5 can also be provided with toothed part 72 as needed; multiple second blocking members 6 or third blocking members 7 can be provided as needed.

[0046] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
