[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 5 This utility model provides a washbasin, including a countertop 1 and a sealing component 2. The countertop 1 is recessed to form a water storage tank 10. A drain hole 11 is provided at the bottom of the water storage tank 10. A guide hole 12 is provided on the countertop 1, which penetrates the countertop 1 and communicates with the drain hole 11 and the guide hole 12. A filter screen 13 is provided at the bottom of the guide hole 12, which is located below the drain hole 11. The sealing component 2 is movably disposed in the guide hole 12 and is used to seal the filter screen 13. The sealing component 2 has buoyancy. When the liquid level in the water storage tank 10 is flush with the liquid level in the guide hole 12, the sealing component 2 floats upward and opens the filter screen 13.

[0023] Specifically, the sealing assembly 2 includes a screw cap 21, a connecting rod 22, a float 23, and a sealing cap 24. The screw cap 21 and the sealing cap 24 are respectively connected to both ends of the connecting rod 22. The float 23 is disposed on the rod body of the connecting rod 22. The screw cap 21 is rotatably disposed at the opening of the guide hole 12. The screw cap 21 has a plurality of first wedge-shaped protrusions 218 protruding from it. The inner wall of the guide hole 12 has a plurality of protrusions corresponding to the first wedge-shaped protrusions. The first wedge-shaped protrusion 218 is adapted to the second wedge-shaped protrusion 14. The first wedge-shaped protrusion 218 is used to engage between two adjacent second wedge-shaped protrusions 14 to drive the sealing cap 24 to seal the filter screen 13, or to abut against the top of the second wedge-shaped protrusions 14 to drive the sealing cap 24 to open the filter screen 13. When the liquid level in the water storage tank 10 is flush with the liquid level in the guide hole 12, the float 23 floats upward to open the filter screen 13. When the first wedge-shaped protrusion 218 engages between two adjacent second wedge-shaped protrusions 14, the overall height of the screw cap 21, connecting rod 22, float 23 and sealing cap 24 decreases, thereby causing the sealing cap 24 to cover the filter screen 13. Therefore, the water in the water storage tank 10 is discharged from the drain hole 11 into the guide hole 12. As the filter screen 13 is blocked by the sealing cap 24, water gradually begins to accumulate in the guide hole 12, and the liquid level in the guide hole 12 rises accordingly. When the liquid level in the guide hole 12 rises to the float 23, the float 23, under the action of buoyancy, drives the screw cap 21, connecting rod 22, and sealing cap 24 to rise together, and the filter screen 13 is reopened. When the unnecessary sealing cap 24 blocks the filter screen 13, that is, when the water in the water storage tank 10 needs to be discharged directly from the drain hole 11 to the filter screen 13, the screw cap 21 is rotated so that the first wedge-shaped protrusion 218 abuts against the top of the second wedge-shaped protrusion 14, thereby positioning the sealing cap 24 above the drain hole 11, preventing the sealing cap 24 from affecting the normal drainage of water.

[0024] In one feasible embodiment, a limiting groove 211 is formed on the outer peripheral wall of the screw cap 21. The contour of the limiting groove 211 is the same as the contour of the first wedge-shaped protrusion 218. A limiting protrusion 121 is provided on the inner wall surface of the guide hole 12. The limiting protrusion 121 is engaged in the limiting groove 211 to limit the rotation angle of the screw cap 21. In this embodiment, when the screw cap 21 is driven to move upward due to buoyancy, the limiting groove 211 and the limiting protrusion 121 cause the screw cap 21 to rotate, thereby allowing the first wedge-shaped protrusion 218 to abut against the top of the second wedge-shaped protrusion 14, thus determining the position of the sealing cap 24 and preventing the sealing cap 24 from re-sealing the filter screen 13. In addition, the water in the water storage tank 10 needs to be discharged directly from the drain hole 11 to the filter screen 13. Rotate the screw cap 21 so that the limiting protrusion 121 abuts against the end of the limiting groove 211, thereby avoiding excessive rotation of the screw cap 21, which would cause the first wedge protrusion to re-enter the gap between the second wedge protrusion 14.

[0025] Further, the limiting groove 211 includes a first horizontal portion 212, an inclined portion 213, and a second horizontal portion 214. The inclined portion 213 connects the first horizontal portion 212 and the second horizontal portion 214. The first horizontal portion 212 is located below the second horizontal portion 214. A vertical portion 215 is connected to one end of the first horizontal portion 212 away from the inclined portion 213. The vertical portion 215 allows the limiting protrusion 121 to disengage from the limiting groove 211. Specifically, the vertical portion 215 penetrates the bottom of the screw cap 21. When it is necessary to remove the sealing assembly 2 from the guide hole 12, the screw cap 24 is screwed to rotate the limiting protrusion 121 to the position corresponding to the vertical portion, and the screw cap 21 is removed in the vertical direction.

[0026] In one feasible embodiment, the rod body of the connecting rod 22 is threadedly connected to the float 23 to adjust the height of the float 23 on the connecting rod 22. The height of the float 23 on the connecting rod 22 can be adjusted by screwing on the float 23. When the height of the float 23 is lower, the water storage capacity of the reservoir is also lower; when the height of the float 23 is higher, the water storage capacity of the reservoir is also higher.

[0027] In one feasible embodiment, the screw cap 21 includes a cap body 216 and a cylindrical body 217. The diameter of the cap body 216 is larger than the diameter of the cylindrical body 217. The cap body 216 abuts against the end of the guide hole 12, and the cylindrical body 217 is inserted into the cylindrical body 217 of the guide hole 12.

[0028] In one feasible embodiment, the cover 216 is recessed to form a receiving groove 219, and a handle 210 is protruding in the receiving groove 219, which can be used to screw the screw cap 21.

[0029] In one feasible implementation, the upper surface of the countertop 1 slopes upwards from the edge of the water reservoir 10 towards the edge of the countertop 1. Existing washbasins are limited in type, and none are specifically designed for the elderly. Existing washbasins are mainly for simple washing and do not consider the impact of elderly people's movements while using them, such as reaching for items. Many elderly people get their clothes soaked by the water from the washbasin, and the floor becomes slippery, posing safety hazards. Therefore, the countertop 1 of the washbasin in this application is sloped at a 15-degree angle, which effectively prevents water from splashing onto the elderly person's clothes and avoids water accumulation on the countertop 1. Furthermore, a temperature voice prompt can be installed next to the faucet to indicate the water temperature and prevent scalding. Further, racks for hanging towels, toothpaste, and drinking cups are provided on both sides of the washbasin.

[0030] In one feasible embodiment, the bottom of the water storage tank 10 slopes downward from the side away from the drain hole 11 toward the side where the drain hole 11 is located. This embodiment effectively prevents water accumulation at the bottom of the water storage tank 10.

[0031] In one feasible embodiment, the countertop 1 is provided with handrails 220, which are located on both sides of the water tank 10. The handrails in this embodiment provide support for elderly people when using the washbasin.

[0032] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalent elements of the claims are intended to be included within this application.
