[0002] A kitchen sink is a vessel used to hold large amounts of water and for washing dishes and food. Its primary material is stainless steel. Besides stainless steel, other materials include enamel iron and ceramic. Kitchen sinks are categorized by material: cast iron enamel, ceramic, stainless steel, artificial stone, granite, enamel steel, acrylic, and crystallized stone sinks. They are also categorized by style: single-basin sinks, double-basin sinks, large and small double-basin sinks, and irregularly shaped double-basin sinks. The sink manufacturing process involves four steps: welding and stretching, surface treatment, edge and corner finishing, and bottom spraying. The sink stamping die is a crucial component in the stretching process. Stainless steel sinks are popular among consumers due to their good sealing properties and durability. Stainless steel sinks manufactured through integral stamping are particularly efficient and widely used.

[0026] Please refer to the following: Figures 1 to 2 This utility model provides a composite double-layer stainless steel water tank 10, which includes: a stainless steel inner tank 100, a stainless steel outer tank 200, and a sealing mechanism 300.

[0027] A discharge pipe 110 is provided in the middle area of ​​the stainless steel inner liner 100. In this embodiment, the discharge pipe 110 is integrally formed with the stainless steel inner liner 100. A receiving groove 101 is formed around the discharge pipe 110 in the stainless steel inner liner 100. The receiving groove 101 is used to receive an external filter cartridge. A plurality of limiting blocks 111 are evenly arranged in a circular pattern on the inner wall of the end of the discharge pipe 110 away from the stainless steel inner liner 100 to accommodate the external filter cartridge. In this embodiment, each limiting block 111 is integrally formed with the discharge pipe 110. A plurality of limiting posts 120 are evenly arranged on the outer wall of the bottom of the stainless steel inner liner 100. In this embodiment, each limiting post 120 is integrally formed with the stainless steel inner liner 100. The limiting post 120 has a cylindrical structure. In another embodiment, the limiting post 120 has a quadrangular prism structure.

[0028] A stainless steel inner liner 100 and a stainless steel outer tank 200 are fitted together, with the inner liner 100 inserted into the outer tank 200. A buffer rubber layer 400 is filled between the inner liner 100 and the outer tank 200. Several limiting grooves 401 are evenly distributed on the side of the buffer rubber layer 400 facing the inner liner 100. Each limiting groove 401 is fitted with a limiting post 120, and each limiting post 120 is inserted into a corresponding limiting groove 401. The edge plates of the inner liner 100 and the outer tank 200 are welded together. A through hole 201 is provided at the bottom of the outer tank 200, and a discharge pipe 110 is fitted into the through hole 201, passing through it.

[0029] The sealing mechanism 300 includes a sealing washer 310 and a fastening threaded ring 320. The sealing washer 310 is fitted onto the discharge pipe 110 and abuts against the outer wall of the stainless steel outer groove 200. The fastening threaded ring 320 is adapted to the discharge pipe 110 and is fitted onto and screwed onto the discharge pipe 110. The fastening threaded ring 320 abuts against the sealing washer 310. A rotating handle 321 is provided on the outer wall of the fastening threaded ring 320. In this embodiment, the rotating handle 321 and the fastening threaded ring 320 are integrally formed. The rotating handle 321 is provided with anti-slip texture to increase its anti-slip performance. Furthermore, two rotating handles 321 are symmetrically arranged on both sides of the outer wall of the fastening threaded ring 320. The rotating handle 321 has a cylindrical structure.

[0030] During operation, the aforementioned composite double-layer stainless steel water tank 10 utilizes the buffer rubber layer 400 to effectively buffer and reduce pressure, thereby minimizing noise during use. During assembly, the buffer rubber layer 400 is adhered to the inner wall of the stainless steel outer tank 200, and the stainless steel inner liner 100 is inserted into the stainless steel outer tank 200. In this process, each limiting post 120 is inserted into a corresponding limiting groove 401, and the discharge pipe 110 passes through the through hole 201. The edge plates of the stainless steel inner liner 100 and the stainless steel outer tank 200 are then welded together. A sealing gasket 310 is fitted onto the discharge pipe 110 and abuts against the outer wall of the stainless steel outer tank 200. A fastening threaded ring 320 is fitted onto the discharge pipe 110 and screwed onto it, so that the fastening threaded ring 320 abuts against the sealing gasket 310, sealing the gap between the stainless steel outer tank 200 and the discharge pipe 110. This prevents external moisture and dirt from entering the space between the stainless steel inner tank 100 and the stainless steel outer tank 200 through the gap between the stainless steel outer tank 200 and the discharge pipe 110. The aforementioned composite double-layer stainless steel water tank 10 generates relatively little noise during use.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
