[0002] Caffeine in coffee can stimulate the central nervous system, improve people's attention and alertness. During work, appropriate intake of coffee can improve work efficiency, reaction ability and thinking agility, and is deeply loved by office workers. Instant coffee is quick to brew and has become the first choice of office workers. To have a better taste, usually the brewed coffee needs to be kept at an appropriate temperature when being drunk.

[0003] However, the current coffee cups are basically simple single-layer structures, and the hot drinks after brewing cannot be kept warm after cooling. In addition, the current coffee cups basically rely on the user to manually stir to dissolve the coffee and reduce the temperature of the hot drink, and the cooling speed is slow.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1-7 shown, the present utility model provides a coffee cup with automatic stirring and heat preservation functions, which is mainly used to meet the requirements of cooling, heat preservation and automatic stirring when brewing hot drinks. The structure of the coffee cup mainly includes a cup body 1 and an inner liner 2. The inner liner 2 is placed inside the cup body 1. The top of the inner liner 2 is connected to the top of the cup body 1 to form a double-layer structure, so that a sealed cavity 3 is formed between the outer wall of the inner liner 2 and the inner wall of the cup body 1. When in use, the user needs to pour hot water and brewing materials into the inner liner 2.

[0024] To achieve the heat preservation effect of the coffee cup, a phase change material layer 4 for cooling and heat preservation is added in the cavity 3. Among them, the phase change material layer 4 is installed in the cavity 3 and closely adheres to the outer wall of the inner liner 2. When hot water is poured into the inner liner 2, part of the heat released by the hot water will be absorbed by the phase change material layer 4 through the inner liner 2, so as to cool the hot water. When the hot water cools down to the specified temperature, the phase change material layer 4 will keep the hot water warm. For example: when the user brews a hot drink and pours 100°C hot water into the inner liner 2, part of the heat of the hot water is absorbed by the phase change material layer 4, and the temperature of the hot water will drop. When the temperature of the hot water drops to 60°C, the phase change material layer 4 will keep the hot water warm for the convenience of the user to drink.

[0025] In order to further accelerate the cooling speed of the hot water, the coffee cup can also quickly cool the hot water through the function of automatically stirring at the bottom of the inner liner 2. The specific structure is that a semiconductor refrigeration sheet 5, an aluminum sheet 6 and a rotating motor 7 are installed at one end of the cavity 3 close to the bottom of the inner liner 2. A magnetic block 8 controlled by the rotating motor 7 to rotate is connected to the output shaft of the rotating motor 7. Moreover, the magnetic block 8 is arranged to rotate below the inner liner 2. At the same time, a magnetic stirrer 9 that is magnetically attracted to the magnetic block 8 after sinking is placed at the position where hot water is contained inside the inner liner 2, and the magnetic stirrer 9 is driven to stir by the rotation of the magnetic block 8. It should be added that to complete the stirring action, the rotating motor 7 needs to be powered on, otherwise the stirring will stop.

[0026] To achieve the effect of being powered on, this solution utilizes a thermoelectric cooler 5 to complete the task. Electricity is generated through the temperature difference at both ends of the thermoelectric cooler 5. When the thermoelectric cooler 5 is connected, one end of the thermoelectric cooler 5 is closely attached to the bottom of the inner container 2, and the other end of the thermoelectric cooler 5 is connected to the aluminum sheet 6. At this time, the temperature after heat dissipation of the aluminum sheet 6 is 30°C. When hot water is poured into the inner container 2, a large temperature difference is formed at both ends of the thermoelectric cooler 5. The thermoelectric cooler 5 generates electrical energy based on the Seebeck effect in the thermoelectric effect. The electrical energy generated at this time is used to supply the rotating motor 7 for stirring. As the temperature of the hot water in the inner container 2 decreases, when the temperature of the hot water drops to 60°C, the temperature difference at both ends of the thermoelectric cooler 5 is not sufficient to form the condition for generating electricity. At this time, power supply to the rotating motor 7 can no longer continue. After the rotating motor 7 stops, the stirring stops. At this time, the temperature of the hot water is also set at 60°C and is insulated by the phase change material layer 4.

[0027] In addition, a handle 10 for convenient user holding is connected to one side of the cup body 1. To facilitate the user to know the temperature of the hot water in real time, a display screen 11 for displaying the temperature of the hot water is provided on the handle 10. A temperature sensor in contact with the inner container can be added in the cavity 3. After connecting the display screen 11 with the temperature sensor, the temperature of the hot water can be obtained. The display screen 11 can display in two different temperature measurement units, Fahrenheit temperature and Celsius temperature, for the convenience of different users. When displaying, the Fahrenheit temperature and Celsius temperature, which are two different temperature measurement units, can be switched for use.

[0028] To facilitate the installation of the structure in the cavity 3, a detachable cup base 12 is provided at the bottom of the cup body 1 itself. After the cup base 12 is opened, it can directly reach the position below the inner container 2. The cup base 12 and the cup body 1 can be fixed or disassembled by rotating. Structurally, there are eight locking blocks 13 on the inner wall of the cup base 12, and there are eight locking hooks 14 at one end of the cup body 1 connected to the cup base 12 that are fixed to the locking blocks 13 after rotation. Among them, the positions of the locking hooks 14 and the locking blocks 13 correspond to each other for convenient locking. At the same time, an anti-slip gasket 15 is also provided at the bottom of the cup base 12, and the gasket 15 can be connected by gluing.

[0029] When installing the aluminum sheet 6 and the rotating motor 7 inside the cavity 3, the aluminum sheet 6 is in a ring shape, and a gasket 17 for supporting and fixing is connected to the bottom of the aluminum sheet 6 through a locking member 16, which also ensures that the aluminum sheet 6 does not separate from the thermoelectric cooler 5. The rotating motor 7 is arranged in the middle of the aluminum sheet 6 and is fixed by the gasket 17 at the same time.

[0030] Compared with the traditional technology, in the technical solution, a phase change material layer 4 is provided at the position of the cavity 3 of the coffee cup, which is closely attached to the outer wall of the inner liner 2, so as to reduce the temperature of the hot water and achieve the effect of heat preservation through the phase change material layer 4. At the same time, in the cavity 3, an electric current is generated by the temperature difference at both ends of the semiconductor refrigeration sheet 5 to supply power to the rotating motor 7 to rotate and stir the hot water, so as to overall accelerate the cooling speed of the hot water and achieve the effect of heat preservation.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model, and any reference signs in the claims should not be regarded as limiting the claims involved.
