[0002] The cup comprises a cup body. Currently, cups on the market have only one chamber in the cup body which can store only one liquid, and thus cannot meet the needs of users who want to store and drink two liquids in one cup.

[0003] At present, there are cups on the market that can store two liquids in the cup body. The reference publication number is CN202161104U, and the name is a utility model patent for a cup in a cup, which includes a cup body and a cup cover. The cup body is provided with a partition, and the partition divides the cup body into an inner cup body and an outer cup body. The partition is a single layer, and the outer wall of the outer cup body is also a single layer. The structure and material are not reasonable, resulting in a low heat preservation effect of the cup body. How to take into account the function of storing two liquids and the heat preservation function of the cup at the same time is a problem that designers have yet to solve. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a double-cavity thermos cup, which solves the problem that the function of storing two liquids and the heat preservation function cannot be taken into account at the same time.

[0005] The technical solution adopted by the utility model is: a double-chamber thermos cup, including a cup cover and a cup body, the cup body including an inner cavity and an outer cavity, the outer cavity is arranged around the circumference of the inner cavity, the cup cover is provided with a first drinking water unit corresponding to the inner cavity and a second drinking water unit corresponding to the outer cavity, the circumference and bottom of the cup body together form a first vacuum insulation layer, various places on the cup body are fixedly connected into a whole, and the cup body is made of metal or alloy material.

[0006] Through the above technical solution, liquids of different temperatures or different types can be stored in the inner cavity and the outer cavity respectively, meeting the needs of users who want to store and drink different liquids in one cup. In addition, the entire cup body is made of metal or alloy material and a first vacuum insulation layer is provided at the same time, so that the efficiency of exchange between the liquid in the inner cavity and the outer cavity and the external temperature is lower, and the insulation effect is better.

[0007] Furthermore, the cup body includes an outer cup wall, a connecting inner wall and an inner bottle, and the outer cup wall, the connecting inner wall and the inner bottle are arranged in sequence from the outside to the inside, the top of the connecting inner wall is connected to the outer cup wall, and the bottom of the connecting inner wall is connected to the inner bottle; the first vacuum insulation layer is located between the inner bottle and the connecting inner wall and the outer cup wall, the outer cavity is located between the connecting inner wall and the inner bottle, and the inner cavity is the internal space of the inner bottle.

[0008] Through the above technical solution, the cup body has a simple structure and is easy to produce. The first vacuum insulation layer, the outer cavity and the inner cavity are reasonably arranged to meet the requirements of storing two kinds of liquids simultaneously and the insulation requirement.

[0009] Further, the inner liner bottle includes a bottle mouth part, a first inclined cone surface and a second inclined cone surface which are connected in sequence. An annular convex edge is formed at the turning point between the first inclined cone surface and the second inclined cone surface, and the bottom of the connecting inner wall is fixedly welded to the annular convex edge.

[0010] Through the above technical solution, the annular convex edge is the place with the largest diameter on the inner liner bottle. The annular convex edge and the bottom of the connecting inner wall are adapted, which is convenient for the annular convex edge to be docked and fixedly welded with the connecting bottom, making the production more convenient.

[0011] Further, the connecting inner wall includes a cylindrical part and an inclined cone necking. The inclined cone necking is integrally formed at the bottom of the cylindrical part. The diameter of the inclined cone necking gradually decreases from top to bottom, and the bottom of the inclined cone necking is fixedly welded to the annular convex edge.

[0012] Through the above technical solution, the cylindrical part and the inclined cone necking make the volume of the outer cavity larger, so that more liquid can be accommodated in the outer cavity, reducing the frequency of adding liquid to the outer cavity and making the use more convenient.

[0013] Further, the cup body includes an outer cup wall, a connecting inner wall, an inner liner outer wall and an inner liner bottle. The outer cup wall, the connecting inner wall, the inner liner outer wall and the inner liner bottle are connected in sequence from outside to inside. The first vacuum insulation layer is formed between the outside of the connecting inner wall and the bottom of the inner liner bottle and the outer cup wall. The outer cavity is formed between the connecting inner wall and the inner liner outer wall. The inner cavity is the internal space of the inner liner bottle. A second vacuum insulation layer is formed between the inner liner outer wall and the inner liner bottle.

[0014] Through the above technical solution, the setting of the first vacuum insulation layer reduces the rate of temperature exchange between the liquids in the inner cavity and the outer cavity and the outside world, making the insulation effect better.

[0015] Further, the first drinking unit includes a nozzle and a straw. A water passing hole is provided on the cup cover. The straw is connected to the cup cover and communicated with the water passing hole. The nozzle is rotatably connected to the cup cover; when the nozzle rotates to the vertical state, the nozzle is communicated with the water passing hole.

[0016] Through the above technical solution, when the nozzle rotates to the vertical state, the nozzle, the water passing hole and the straw are communicated with each other. The user can drink the liquid in the inner cavity by sucking the nozzle, which is convenient to use. When the nozzle rotates to the horizontal state, the nozzle closes the water passing hole and reduces the overall volume of the thermos cup of the present invention, which is convenient to carry and store.

[0017] Furthermore, the first drinking unit is a direct drinking port, which is opened on the cup lid and located above the outer cavity. A flip cover is rotatably connected to the cup lid, and a sealing block for blocking the direct drinking port is arranged on the flip cover.

[0018] Through the above technical solution, the flip cover can be opened to drink the liquid in the outer cavity through the direct drinking port, which is very convenient to use. The first drinking unit and the second drinking unit respectively adopt the methods of sucking and direct drinking for drinking water, providing more choices for users and making the design more user-friendly.

[0019] Furthermore, the cup lid includes an outer peripheral block and an inner peripheral block. The outer peripheral block is threadedly connected to the connecting inner wall or the outer cup wall. A sealing ring is sleeved on the inner peripheral block, and the sealing ring abuts against the inner wall of the opening of the inner liner bottle.

[0020] Through the above technical solution, the outer peripheral block and the inner peripheral block on the cup lid form a sealed space with the outer cavity, and the inner peripheral block and the inner cavity form a sealed space, so that the liquids in the inner cavity and the outer cavity will not mix with each other, and the exchange rate of the liquids in the inner cavity and the outer cavity is also reduced, resulting in a decrease in the temperature exchange efficiency between the outer cavity and the inner cavity and better heat preservation effect.
