[0025] The present application will be described in detail below in conjunction with the drawings.

[0026] A high-sealing vacuum cup, as shown in Figures 1 to 3 It comprises a cup body 1 and a cup cover 2, characterized in that: the inside of the cup body 1 is provided with an inner container 3, a heat preservation layer 4 is fixedly mounted between the inner container 3 and the outer shell of the cup body 1, a threaded cup mouth 5 is fixedly mounted at the upper end of the cup body 1, and a high-temperature-resistant rubber sealing ring 6 is fixedly mounted at the lower side of the outer surface of the cup cover 2.

[0027] As shown in Figure 1 The bottom of the cup body 1 is fixedly mounted with an anti-skid base 7, which is usually made of rubber or other materials with high friction coefficient. When the vacuum cup is placed on a flat surface, the large friction force generated between the base and the contact surface can effectively prevent the cup from moving, especially when used on a smooth surface.

[0028] As shown in Figure 1 A temperature display screen 8 is fixedly mounted on the outer surface of the cup body 1. The temperature display screen 8 detects the temperature of the liquid in the cup through the built-in temperature sensor, and converts the data into visual digital information displayed on the screen. This not only allows the user to keep track of the temperature of the beverage at any time, avoiding the risk of burns, but also improves the convenience of use. The built-in button cell of the temperature display screen 8 can provide sufficient power support and occupy small space.

[0029] AsFigure 1 As shown, the outer surface of the cup body 1 is fixedly installed with a handle 9, which is usually ergonomically designed to ensure that the user feels comfortable and stable when holding it. In addition, the presence of the handle 9 also reduces the heat conduction caused by directly holding the cup body, so that even a thermos cup filled with hot drink can be safely taken.

[0030] A manufacturing process of a thermos cup, characterized in that it comprises the following steps:

[0031] S1. Assemble the inner container and the thermal layer, place the stainless steel inner container 3 inside the cup body 1 shell, inject vacuum insulation material into the gap between the inner container 3 and the cup body 1 shell, and seal and solidify after vacuumizing to form the thermal layer 4;

[0032] S2. Form the cup assembly: laser weld the stainless steel threaded cup mouth 5 on the upper end of the cup body 1, fix the anti-slip base 7 to the bottom of the cup body 1 with food-grade adhesive, and perform pressure curing;

[0033] S3. Install external functional parts: pre-drill mounting slots on the surface of the cup body 1 shell, embed the temperature display screen 8 and seal weld, and use high-frequency welding process to fix the handle 9 on the symmetric sides of the cup body 1 shell;

[0034] S4. Assemble the cup cover sealing system: press-fit the high-temperature-resistant rubber sealing ring 6 in the annular groove at the lower end of the cup cover 2, and apply a pre-compression of 15%-20% to the sealing ring after installation;

[0035] S5. Overall verification test: air tightness test of the threaded cup mouth 5 and the cup cover 2: apply 0.05 MPa air pressure, no leakage for 60 s, perform thermal insulation performance test: inject 95℃ hot water, the water temperature is ≥75℃ after 24 hours.

[0036] Working principle: the cup body 1 is provided with an inner container 3, and a thermal layer 4 is fixedly installed between the inner container 3 and the cup body 1 shell. By placing the inner container 3 inside the cup body 1 shell and injecting vacuum insulation material into the gap between the two, a high-efficiency thermal layer 4 is formed after vacuumizing and sealing and solidifying. The threaded cup mouth 5 is fixedly installed on the upper end of the cup body 1, and the high-temperature-resistant rubber sealing ring 6 is fixedly installed on the outer surface of the cup cover 2. This design ensures the sealing of the cup in the closed state and prevents liquid leakage. The anti-slip base 7 is fixedly installed on the bottom of the cup body 1, increasing the stability and safety of use. The temperature display screen 8 is fixedly installed on the outer surface of the cup body 1, making it convenient for users to know the temperature of the liquid in the cup in real time. At the same time, the handle 9 is also fixedly installed on the outer surface of the cup body 1, making it convenient to carry and use. The integration of the temperature display screen 8, the anti-slip base 7 and the handle 9 and other practical functions makes the thermos cup not only limited to basic thermal insulation, but also provides users with more convenience and operational flexibility.

[0037] The above merely describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-described embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
