[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Reference Figure 1 to Figure 3 A heating device with a magnetic attraction structure comprises a main body 1, a power supply device 2 and a heating device 3, wherein a temperature sensor 4 is arranged in the heating device 3, the main body 1 heats the heating device 3, the power supply device 2 is arranged in the main body 1, a first magnetic attraction head 5 is arranged on the main body 1, and the first magnetic attraction head 5 is electrically connected to the power supply device 2, a second magnetic attraction head 6 is arranged on the heating device 3, the first magnetic attraction head 5 is electrically connected to the second magnetic attraction head 6, the temperature sensor 4 is electrically connected to the second magnetic attraction head 6, a control board 7 is arranged in the main body 1, and the temperature sensor 4 is electrically connected to the control board 7. The control board 7 is an existing commonly used circuit board, which can receive the signal of the temperature sensor 4, and control the power supply device 2 and the heating device 3 to be connected or disconnected according to the temperature, so as to control the heating condition of the heating device 3.

[0019] When it is necessary to heat the liquid in the heating device 3, the second magnetic suction head 6 on the heating device 3 is placed opposite to the first magnetic suction head 5 on the body 1, and the two magnetic suction heads are tightly attracted by magnetic force. Through the magnetic force, the two can be automatically adsorbed when they are close to each other, thereby electrically connecting the power supply device 2 with the temperature sensor 4. After the temperature sensor 4 is powered on, the temperature signal of the temperature sensor 4 is transmitted to the control board 7, and the control board 7 then recognizes the signal and performs temperature control and heating. Since the temperature sensor 4 is located in the heating device 3, the temperature in the heating device 3 can be accurately measured, thereby improving the accuracy of temperature detection.

[0020] The first magnetic head 5 is a female magnetic seat, and the second magnetic head 6 is a male magnetic seat. In actual use, the first magnetic head 5 can also be a male magnetic seat, and the second magnetic head 6 can be a female magnetic seat. Through the cooperation of the male magnetic seat and the female magnetic seat, the wires of the two can be connected, and the electrical connection between the two can be achieved, so that the temperature sensor 4 can be powered conveniently. Since the two magnetic heads can only be tightly attracted by magnetic force when they are close to each other, the second magnetic head 6 and the first magnetic head 5 can be tightly attracted after the heating device 3 is placed in place, so that the placement position of the heating device 3 can be judged. The heating device 3 needs to be placed in place to achieve the connection between the two magnetic heads, and then the temperature sensor 4 can transmit the signal to the control board 7, and the signal can be transmitted to the power supply device 2 through the control board 7, which is convenient for the circuit to be connected.

Specifically, a mounting groove may be provided on the bracket 9, and the heating plate 8 is pressed into the mounting groove, and the outer edge of the heating plate 8 is clamped with the inner wall of the mounting groove to fix the heating plate 8.

[0024] The body 1 also includes a fan 13, which is fixed in the housing 11. The housing 11 is provided with a ventilation hole 111, and the fan 13 is located below the coil disk 12. The ventilation hole 111 facilitates convection between the air in the body 1 and the outside air, and facilitates the dissipation of heat. The fan 13 is electrically connected to the power board 21 through a wire, which facilitates the connection between the fan 13 and the external power supply. Through the fan 13, the components in the body 1 can be cooled, the circulation of air in the body 1 can be accelerated, and the temperature of the components such as the coil disk 12 and the power board 21 can be avoided from being too high, which plays a protective role.

When the temperature signal of the temperature sensor 4 is transmitted to the control board 7, the control board 7 can control the connection between the power board 21 and the coil disk 12. Specifically, when the heating temperature in the heating device reaches the required temperature, the temperature signal is transmitted to the control board 7, and the control board 7 can control the power board 21 to stop supplying power to the coil disk 12, thereby stopping the coil disk 12 from continuing to heat the heating plate 8, thereby achieving a temperature control effect.

[0026] The body 1 is provided with a placement groove 14, and the heating device 3 is placed on the placement groove 14. Among them, the placement groove 14 can be opened horizontally, so as to facilitate the placement of the heating device 3 in a horizontal state.
