[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 4 The present invention provides a heat dissipation and insulation cup with automatic temperature control, comprising a cup body and a cup cover, wherein the cup cover comprises a fixed part and a movable part.

[0022] The fixed part is annular, and the middle part of the annular shape is used to contain the hot air of high-temperature hot water, which is convenient for the subsequent airflow guidance. A hollow fixed tube is provided on the side of the fixed part facing the movable part, an opening is provided on the end face of the fixed tube facing the movable part, a first ventilation hole is provided on the outer circumferential surface of the fixed tube, a first ferromagnetic metal is provided on the inner bottom surface of the fixed tube, and a thread is provided on the side of the fixed part facing the cup body to connect with the cup body thread. The fixed tube can be set in the middle or any position of the annular shape of the fixed part, and is used to determine the push-out positioning point for pushing the movable part away from the fixed part. Therefore, it can be directly set in the middle position to facilitate the use of a fixed tube to push the entire movable part away from the fixed part; it can also be set in pairs with the center of the annular fixed part as the symmetrical point to push the entire movable part away from the fixed part; it can also be set only on one side of the annular fixed part to push part of the movable part away from the fixed part to form a gap, and a hinged structure is set at its symmetrical position, etc., which can enable the movable part and the fixed part to form a conventional design of a flip cover structure.

[0023] The movable part is provided with a fan, a fan motor, a control circuit board, a battery and a heat preservation layer in sequence from the end away from the cup body to the cup body. The movable part is also provided with a ventilation pipe, one end of which is connected to the fan, and the other end of the ventilation pipe is coaxially connected to the inner bottom surface of the fixed pipe through a spring, so that the space where the fan is located is directly connected to the external air, which is convenient for heat to be quickly dissipated to the outside. The end face of the other end of the ventilation pipe is provided with a first electromagnet electrically connected to the control circuit board. The outer circumferential surface of the ventilation pipe is provided with a second ventilation hole. When the first electromagnet is magnetically connected to the ferromagnetic metal, the first ventilation hole is aligned with the second ventilation hole, that is, when the first electromagnet is magnetically attracted to the first ferromagnetic metal, the ventilation pipe can attract the hot air in the fixed part under the action of the fan. Among them, the first ventilation hole and the second ventilation hole should be oriented toward the center of the annular fixed part so as to absorb the hot air concentrated in the middle of the annular fixed part. When the movable part is separated from the fixed part, the hot air in the fixed part is sucked away from the ventilation pipe, so that the external cold air enters from the opening between the fixed part and the movable part, forming an air flow circulation and enhancing the heat dissipation effect.

[0024] A temperature sensor electrically connected to the control circuit board is provided in the cup cover to sense the temperature in the cup body and realize the temperature control function. The temperature sensor can be arranged on the surface of the side of the thermal insulation layer of the moving part close to the cup body, or on the surface of the annular inner wall of the fixed part. The specific position can be set arbitrarily according to the actual situation, but in order to connect with the control circuit board, the temperature sensor must be arranged in the cup cover.

[0025] A rubber ring is provided between the fixed part and the movable part to prevent structural damage caused by frequent opening and closing between the fixed part and the movable part and to enhance the sealing performance and improve the heat preservation effect when the fixed part and the movable part are closed.

[0026] A hole facing the ventilation pipe is provided in the fixed part, a protrusion is provided in the hole, the protrusion is connected to the end face of the hole through a spring, a second ferromagnetic metal is provided on the part of the protrusion facing the end face of the hole, a second electromagnet is provided on the end face of the hole, a hole for accommodating the protrusion is provided on the outer circumferential surface of the ventilation pipe, and when the first electromagnet attracts the first ferromagnetic metal, the protrusion is ejected in a direction away from the end face and inserted into the hole under the action of the spring. When the fixed part and the movable part are closed, the first electromagnet is no longer required to be continuously energized to attract the first ferromagnetic metal, so that the fixed part and the movable part can be mechanically locked by using the cooperation of the protrusion and the hole in the closed state, thereby achieving the effect of power saving.

[0027] A control button electrically connected to the control circuit board is provided on the outer side of the cup cover, so as to facilitate active control of the various components in the present solution.

[0028] A method for automatically controlling the temperature and dissipating heat of a thermos cup applied to the above-mentioned automatic temperature-controlled heat-dissipating thermos cup comprises the following steps: S1. The preset temperature that needs to be kept warm is preset by the control circuit board. For example, if the temperature that needs to be kept warm is 60°C, the preset temperature is set to 60°C. After high-temperature hot water is put into the cup body, the fixed part of the cup cover is connected to the cup body so that the cup cover and the cup body are fixedly connected. In the initial state, the control circuit board controls the first electromagnet to energize and attract the ventilation pipe so that the moving part and the fixed part fit together, and the first ventilation hole and the second ventilation hole are staggered, so that the space between the fixed part and the moving part is in a closed state, thereby achieving a heat preservation effect.

[0029] S2. The actual temperature in the cup body is monitored in real time through the temperature sensor, and the actual temperature is compared with the preset temperature in real time for subsequent automatic control.

[0030] S3. When the actual temperature is higher than the preset temperature, the control circuit board turns off the power supply of the first electromagnet so that the first electromagnet loses its magnetic attraction to the ventilation tube. Under the action of the spring, the ventilation tube pops up in the direction away from the cup body and lifts up the movable part of the cup cover, and aligns the first ventilation hole with the second ventilation hole, thereby forming an opening between the fixed part and the movable part so that the internal space of the fixed part is connected to the external air. At the same time, the control circuit board drives the fan to rotate so that the hot air in the center of the fixed part flows out through the ventilation tube toward the fan, dissipating heat by extracting hot air, and then executing the next step.

[0031] S4. When the actual temperature is equal to the preset temperature, the control circuit board drives the first electromagnet to attract the ventilation tube so that the movable part fits with the fixed part, and the first ventilation hole and the second ventilation hole are staggered. Then the control circuit board controls the fan to be turned off, so that the actual temperature after heat dissipation reaches the preset temperature and then keeps warm.

[0032] Furthermore, in the embodiment of the present scheme including the protrusion, in step S1, when the protrusion is inserted into the hole, the control circuit board controls the first electromagnet to be powered off, so that the moving part and the fixed part are sealed together under the premise of saving power, and the first electromagnet does not need to continuously magnetically attract and maintain the moving part and the fixed part in a state of being in contact. Then in step S3, when there is a situation where the protrusion is inserted into the hole, the control circuit board controls the second electromagnet to attract the protrusion, so that the protrusion is out of the locking state with the hole, and the ventilation pipe is ejected by the spring.

[0033] On the basis of the above implementation scheme, the processors, modules, corresponding control programs, algorithm programs and other supporting technologies mentioned in the present invention can be implemented in combination with existing electrical technology, information technology, software technology and general protocols. They are not within the scope of protection required by the present invention and will not be described in detail in this application.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.
