Description

Technical Field

[0001] This utility model relates to the field of thermos cup structure technology, and in particular to a double-layer thermos cup with good heat preservation effect. Background Technology

[0002] Traditional insulated cups often use a double-walled stainless steel vacuum structure to achieve heat retention. While this type of structure offers good insulation, it is usually molded in one piece or welded together, resulting in complex manufacturing processes, high costs, and the inability to replace the entire cup if the inner liner is damaged, rendering it unusable. Furthermore, the connection between the inner liner, body, and lid of common insulated cups is relatively fixed, making deep cleaning or component replacement difficult and posing significant hygiene risks with long-term use. Additionally, some insulated cups have a simplistic sealing design, relying solely on the seal between the lid and the rim. This can leave tiny heat leakage channels at the threaded connection between the lid and body, affecting overall insulation performance.

[0003] Therefore, there is a need for a new type of thermos cup structure that can solve the problems mentioned above, while ensuring excellent heat preservation performance, and also being modular, detachable, easy to clean, low-cost, and with better sealing. Utility Model Content

[0004] This invention provides a double-layered thermos cup with good heat preservation effect. By making technical modifications to existing thermos cups, the problem of poor heat preservation effect of existing thermos cups is solved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A double-walled insulated cup with good heat preservation includes a lid, a body, an inner liner, and a fixing sleeve. The fixing sleeve is fixedly installed on the upper end of the inner liner. The bottom of the lid has a protruding mounting part. The fixing sleeve is detachably installed on the inner side of the mounting part of the lid, and the outer side of the mounting part is threadedly connected and fixed to the body. A sealing structure is also provided between the lid and the body.

[0006] Preferably, the upper end of the inner liner is recessed inward with an annular groove, and the fixing sleeve is engaged in the annular groove. The inner liner is made of a high-temperature resistant and corrosion-resistant elastic material.

[0007] Preferably, a limiting groove is also provided at the upper end of the annular groove, and the upper end of the fixing sleeve is fitted into the limiting groove.

[0008] Preferably, the outer side of the fixing sleeve is provided with an external thread structure, and the inner side of the mounting part is provided with an internal thread structure, and the external thread structure and the internal thread structure are threadedly connected and fixed.

[0009] Preferably, the sealing structure includes an annular sealing ring, and the bottom surface of the cup lid is further provided with a second annular groove for installing the sealing ring. The inner side of the opening of the cup body is provided with a stepped surface structure, and the sealing ring is installed between the second annular groove and the stepped surface structure.

[0010] Preferably, the bottom surface of the cup body is recessed inward to provide a counterweight groove, and a magnetic counterweight is fixedly installed in the counterweight groove.

[0011] Preferably, the outer surface of the cup body is also provided with anti-slip texture.

[0012] Preferably, the cup lid portion has a handle protruding outwards, and a rope hole is provided through the handle.

[0013] Preferably, the cup lid portion has a side opening on its side and an upper opening on its upper surface, and the side opening and the upper opening are connected.

[0014] The beneficial effects of this utility model are as follows: This application features a cup body and an inner liner separated by space. The inner liner is connected to the cup lid via a detachable fixing sleeve. The cup lid seals the upper opening of the inner liner. Both the cup lid and the cup body are equipped with sealing rings. This application combines the direct seal between the cup lid and the upper opening of the inner liner with the sealing ring structure added at the connection between the cup lid and the cup body to form a multi-layer heat preservation and sealing system, which greatly reduces the path of heat loss and significantly improves the heat preservation performance.

[0015] Furthermore, the inner liner, the fixing sleeve, the lid, and the cup body are all independently detachable. This design not only reduces the difficulty and cost of production and assembly, but more importantly, it allows users to thoroughly clean every corner of the cup, preventing dirt and grime from accumulating and improving hygiene and safety. At the same time, easily damaged parts such as the inner liner can be replaced individually, extending the overall lifespan of the product, aligning with green environmental protection principles, and resulting in lower manufacturing costs.

The fixing sleeve part 4 is detachably installed on the inner side of the mounting part 11 of the cup lid part 1, and the outer side of the mounting part 11 is threadedly connected and fixed to the cup body part 2. A sealing structure 5 is also provided between the cup lid part 1 and the cup body part 2.

[0019] Furthermore, to securely mount the fixing sleeve portion 4 onto the inner liner portion 3, an annular groove 31 is recessed inward at the upper end of the inner liner portion 3. The fixing sleeve portion 4 is engaged within the annular groove 31. The inner liner portion 3 is made of a high-temperature resistant and corrosion-resistant elastic material. Food-grade silicone may be used for the inner liner portion 3.

[0020] Furthermore, in order to make the fixing sleeve part 4 more stable, a limiting groove 32 is also provided at the upper end of the annular groove 31, and the upper end of the fixing sleeve part 4 is fitted into the limiting groove 32.

[0021] During installation, the annular groove 31 at the upper end of the inner liner 3 can be pressed to deform it, making it easy to install the fixing sleeve 4. The annular groove 31 is also provided with a limiting groove 32. The fixing sleeve 4 is tightly fitted with the inner liner 3 through the annular groove 31 and the limiting groove 32, and is reliably connected to the cup lid 1 through threads. The entire connection method is stable and easy to operate, ensuring the structural integrity during use.

[0022] Furthermore, in order to fix the inner liner portion 3 inside the cup lid portion 1, the outer side of the fixing sleeve portion 4 is provided with an external thread structure, and the inner side of the mounting portion 11 is provided with an internal thread structure. The external thread structure and the internal thread structure are threadedly connected and fixedly installed.

[0023] Furthermore, the sealing structure 5 includes an annular sealing ring, and the bottom surface of the cup lid portion 1 is also provided with a second annular groove 12 for installing the sealing ring. The inner side of the opening of the cup body portion 2 is provided with a stepped surface structure 21, and the sealing ring is installed between the second annular groove 12 and the stepped surface structure 21.

[0024] This application combines the direct seal between the lid and the upper opening of the inner liner, as well as the sealing ring structure added at the connection between the lid and the body, to form a multi-layer heat preservation and sealing system, which greatly reduces the path of heat loss and significantly improves the heat preservation performance.

[0025] Furthermore, the bottom surface of the cup body 2 is recessed inward and a counterweight groove 22 is provided, and a magnetic counterweight 6 is fixedly installed in the counterweight groove 22.

[0026] The magnetic weight at the bottom makes the cup more stable and drop-resistant. Furthermore, for a better grip, the outer surface of the cup body 2 is also provided with anti-slip texture 7.

[0027] Furthermore, a handle end 13 protrudes outward on the cup lid part 1, and a rope hole 14 is provided through the handle end 13, through which the rope is fixed to the cup lid part 1.
