The vacuum cup is a cup which realizes heat insulation through a vacuum insulation layer between the inner container and the cup body so as to delay heat dissipation of liquid such as water and the like in the inner container, thereby achieving the purpose of heat preservation. Of course, there are some thermos cups on the market which realize the heat preservation function by ceramic materials.

When water or other liquid is boiled and poured into the thermos cup, the temperature of the liquid in the inner container is kept at a higher temperature for a longer time.

The invention provides a vacuum cup which comprises a first cup body 4 enclosing a vacuum chamber a. Specifically, the first cup 4 may be a single-layered cup made of a thermal insulating material, for example, a ceramic material. The first cup body 4 can also comprise an inner container and an outer cup body, and a vacuum insulation layer between the inner container and the outer cup body realizes heat insulation so as to delay heat dissipation of liquid such as water and the like contained in the inner container, thereby achieving the purpose of heat preservation. The first cup 4 forming the insulating chamber a may have the same structure as the prior art thermos cup. The shape and material structure of the first cup 4 are not described in detail herein.

The vacuum cup of the invention also comprises a second cup body 2, wherein the second cup body 2 encloses a non-heat-preserving chamber b, that is, the second cup body 2 is manufactured by a process without a heat-preserving structure or heat-preserving material. The specific material and shape of the second cup body 2 can be reasonably selected according to the designed thermos cup, and the material and shape of the second cup body 2 are not disclosed herein, so that the technical scheme of the invention is not obstructed for those skilled in the art to understand and implement.

The first cup body 4 and the second cup body 2 of the thermos cup are connected in a circumferential sealing mode, and the liquid outlet is formed in the second cup body 2, namely, the thermos cup comprises a heat preservation chamber a and a non-heat preservation chamber b, and liquid in the heat preservation chamber a needs to flow to the liquid outlet through the non-heat preservation chamber b.

When the drinker is hungry and thirsty, pre-storing a part of liquid in the non-heat-preserving chamber b, wherein the water temperature in the non-heat-preserving chamber b can be basically cooled to the room temperature; when the user is thirsty, the core body assembly 3 is opened to enable the liquid part in the heat preservation chamber a to flow into the non-heat preservation chamber b again, so that the part of high-temperature liquid is mixed with the low-temperature liquid in the non-heat preservation chamber b to reach the temperature suitable for the user to drink, and the drinker can drink immediately without waiting. In summary, the thermos cup provided by the invention is suitable for the requirements of different users, and the application range of the thermos cup is greatly improved.

In a specific embodiment, the second cup body 2 and the first cup body 4 may be arranged up and down, the second cup body 2 is a cylinder with two open ends, and the first cup body 4 may be a cylinder structure with one open end. The lower end opening of the second cup body 2 is sealed with the first cup body 4 in the circumferential direction, and the upper end opening of the second cup body 2 is provided with a liquid outlet which is matched with the cup cover of the thermos cup. The upper end opening of the second cup body 2 can be provided with a thread section, and the cup cover is in thread seal with the thread section of the second cup body 2.

In a specific embodiment, the core assembly 3 includes a mounting seat 31 and a valve core component 32, the mounting seat 31 includes a hollow body with two open ends, a first mounting structure matched with a cup opening of the first cup body 4 and in circumferential sealing connection is arranged at a lower opening of the mounting seat 31, and the first mounting structure capable of achieving the above functions has various forms, such as a threaded sealing connection, a fastening sealing connection and other detachable connection, or a welding fixing or riveting fixing connection and other fixing manners.

The technical solution will be further described by taking the first mounting structure as an example of threads, that is, the mounting seat 31 and the first cup body 4 are connected through internal threads and external threads which are matched with each other. The mounting seat 31 may be provided with internal threads or external threads, and the first cup 4 is provided with threads corresponding to the first cup. The figure shows a schematic structure in which the mounting seat 31 is provided with an internal thread and the upper end of the first cup 4 is provided with an external thread.

Therefore, the core body assemblies 3 can be detachably connected with the first cup body 4 and the second cup body 2, the core body assemblies 3 can be independently replaced, and the use cost of the vacuum cup is reduced. Moreover, the connection mode of the cup cover and the second cup body 2 and the connection mode of the mounting seat 31 and the first cup body 4 can be designed to be the same, so that one cup is multipurpose, and the use flexibility of the thermos cup is greatly improved.

When the drinker wants to drink water, the drinker rotates the second cup body 2 clockwise (or anticlockwise), the valve core component 32 moves along the first track 27 relative to the valve port until the valve core component is separated from the valve port, and the drinker tilts the cup body to enable part of the high-temperature water in the heat-preserving chamber a to flow into the non-heat-preserving chamber b so as to be mixed with the low-temperature water in the non-heat-preserving chamber b, so that the water flowing out of the cup opening can be directly drunk by the drinker.

The second cup body 2 is reversely rotated in an inclined state of the thermos cup so that the valve core component 32 reversely moves to close the valve port, and part of water is always reserved in the non-heat-preserving chamber b for being mixed with high temperature water in the heat-preserving chamber a when the thermos cup is drunk next time.
