[0025] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0026] Please refer to Figure 1 , Figure 2 as well as Figure 3This utility model provides a milk warmer with rapid cooling capability, comprising: a pot body 1, a base 2, a bottom shell 3, a heating element 4, a semiconductor cooling chip 5, a heat-conducting element 6, an electrical connection part 7, and a control circuit board 8. The base 2 is disposed at the bottom of the pot body 1. The bottom shell 3 is connected to the base 2, forming a mounting cavity between the bottom shell 3 and the base 2. The mounting cavity is connected to an air inlet 3a and an air outlet 3b on the side wall of the bottom shell 3. The heating element 4 is disposed at the bottom of the base 2. The semiconductor cooling chip 5 is disposed within the mounting cavity. One end of the heat-conducting element 6 is located within the mounting cavity, abutting against the semiconductor cooling chip 5, and the other end of the heat-conducting element 6 extends through the base 2 into the pot body 1. The electrical connection part 7 is disposed within the bottom shell 3, facing a through hole 3c on the bottom shell 3. The control circuit board 8 is disposed within the bottom shell 3 and electrically connects the heating element 4, the semiconductor cooling chip 5, the heat-conducting element 6, and the electrical connection part 7.

[0027] In practical applications, the rapid cooling formula maker also includes a temperature sensor. One end of the temperature sensor extends through the base 2 into the pot body 1, while the other end is located in the mounting cavity and electrically connected to the control circuit board 8. The electrical connection part 7 connects to the mains power supply via a power cord to power the rapid cooling formula maker. After the heating element 4 is powered on, it heats the water contained in the pot body 1. The temperature sensor is used to detect the water temperature in the pot body 1. When the water temperature in the pot body 1 reaches the boiling water temperature (100℃), the temperature sensor transmits a signal to the control circuit board 8. The control circuit board 8 controls the heating element 4 to turn off the power. At the same time, the control circuit board 8 controls the semiconductor cooling chip 5 to be powered on. The semiconductor cooling chip 5 is based on the Peltier effect, which allows the heat in the pot body 1 to be continuously transferred to the mounting cavity through the heat conduction part 6. Cold air from the outside enters the mounting cavity through the air inlet 3a and is discharged from the mounting cavity through the air outlet, forming a flowing circulating air. During the circulation process, the heat transferred to the mounting cavity is carried out.

[0028] Specifically, the heating element 4 can be a heating tube, heating wire, or electric heating film, and the heat-conducting element 6 can be made of a metal material with good thermal conductivity, such as copper or aluminum alloy.

[0029] It should be noted that, in order to prevent water in the kettle body 1 from leaking out through the gap between the heat-conducting component 6 and the base 2, a sealing ring is provided between the heat-conducting component 6 and the base 2 to seal the gap between them.

[0030] In some preferred embodiments, the cross-sectional area of ​​one end of the heat-conducting element 6 is smaller than the cross-sectional area of ​​the other end of the heat-conducting element 6. This technical solution increases the contact area between the heat-conducting element 6 and the boiling water inside the kettle body 1, thereby increasing the rate at which heat is dissipated from the kettle body 1.

[0031] In some preferred embodiments, the electrical connection portion 7 described above is a power socket. When the electrical connection portion 7 is a power socket, the through hole 3c is formed on the side wall of the bottom shell 3, thus facilitating the connection of the power supply cord to the electrical connection portion 7.

[0032] In some preferred embodiments, the mounting cavity described above includes a heat insulation sleeve 9, which is connected to the chassis 2 and located between the heating element 4 and the thermoelectric cooler 5. This technical solution prevents the heat generated by the heating element 4 during operation from being transferred to the thermoelectric cooler 5, thus ensuring the cooling efficiency of the thermoelectric cooler 5 for the boiling water in the kettle body 1 during operation.

[0033] Specifically, both the heating element 4 and the heat insulation sleeve 9 are annular, and the heating element 4 and the heat insulation sleeve 9 are coaxially arranged.

[0034] To improve the heat dissipation efficiency of the thermoelectric cooler 5, in some preferred embodiments, a heat sink 10 is provided inside the mounting cavity. The heat sink 10 is connected to the bottom of the thermoelectric cooler 5 and surrounds the heat insulation sleeve 9. This technical solution allows the heat absorbed by the thermoelectric cooler 5 from the boiling water in the kettle 1 to be quickly conducted to the mounting cavity through the heat sink 10 and rapidly discharged under the action of circulating air, thereby allowing the water in the kettle 1 to be further and rapidly cooled to a predetermined temperature. Specifically, the heat sink 10 can be heat dissipation fins.

[0035] To ensure that the radiator 10 achieves good heat dissipation efficiency, in some preferred embodiments, a cooling fan 11 is provided inside the mounting cavity. The air inlet of the cooling fan 11 faces the radiator 10, and the air outlet of the cooling fan 11 faces the air outlet 3b. This technical solution increases the airflow velocity under the action of the cooling fan 11, thereby allowing the heat transferred to the mounting cavity through the heat conductor 6, the thermoelectric cooling chip 5, and the radiator 10 after boiling water to be quickly dissipated under the action of the cooling fan 11.

[0036] In some preferred embodiments, the mounting cavity described above has a mounting bracket 12, which is connected to the chassis 2. The heat sink 10 and the cooling fan 11 are both mounted on the mounting bracket 12, and one end of the heat-conducting element 6 is connected to the heat sink (10). Through this technical solution, the heat-conducting element 6, the semiconductor cooling chip 5, and the heat sink 10 can fit together tightly, thereby achieving a good heat transfer effect.

[0037] In some preferred embodiments, the mounting bracket 12 is provided with a mounting position 12a that matches the shape of the cooling fan 11, and the cooling fan 11 is located within the mounting position 12a. This technical solution allows for a more compact structure, thereby reducing the size of the rapidly cooling milk warmer.

[0038] In some preferred embodiments, the mounting bracket 12 is provided with an air guide shroud 13, the air inlet of the air guide shroud 13 facing the air outlet of the cooling fan 11, and the air outlet of the air guide shroud 13 facing the air outlet 3b. This technical solution ensures that the hot air flowing out from the air outlet of the cooling fan 11 can flow out evenly through multiple air outlets 3b under the action of the air guide shroud 13, thus avoiding heat concentration.

[0039] In some preferred embodiments, the aforementioned rapid-cooling formula maker further includes a power base 14. The power base 14 is equipped with a power supply unit 15, and both the power supply unit 15 and the electrical connection unit 7 are couplers. The bottom shell 3 is detachably mounted on the power base 14. When the bottom shell 3 is mounted on the power base 14, the electrical connection unit 7 is electrically connected to the power supply unit 15. This technical solution allows the rapid-cooling formula maker to be powered directly when placed on the power base 14. Compared to the electrical connection unit 7 being a power socket, this eliminates the need for repeated plugging and unplugging of the power cord, making it more convenient to use.

[0040] Understandably, when the power supply unit 15 is a coupler, the through hole 3c can be opened at the bottom of the bottom shell 3. In this way, the milk maker that can be quickly cooled can be taken out and put in by simply going up and down, which is more convenient to use.

[0041] In some preferred embodiments, the air inlet 3a is located slightly above the side wall of the bottom shell 3, and the air outlet 3b is located slightly below the side wall of the bottom shell 3. This design allows the air inlet 3a to be closer to the bottom of the thermoelectric cooler 5, enabling the heat within the mounting cavity to be exhausted as much as possible under the action of circulating air, thus achieving a good heat dissipation effect.

[0042] In summary, in one or more embodiments of this utility model, the rapidly cooling milk warmer of this utility model boils the water in the pot through a heating element and then conducts the heat from the pot to the mounting cavity through a semiconductor cooling chip. This allows the outside cold air entering the mounting cavity through the air inlet and exiting the mounting cavity through the air outlet to carry away the heat from the mounting cavity, thereby enabling the boiling water in the pot to be rapidly cooled to a predetermined temperature, reducing the waiting time compared to natural cooling.

[0043] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
