[0027] like Figures 1 to 4 As shown, some embodiments of the utility model provide a constant temperature heating device for wooden medicinal sticks. The constant temperature heating device for wooden medicinal sticks comprises: a heating unit 1 and a control unit 2. The heating unit 1 is configured to heat the medicinal stick. The heating unit 1 is electrically connected to the control unit 2, and the control unit 2 is configured to provide power to the heating unit 1 and control the current.
[0028] The heating unit 1 includes a heating element. The heating element is a pipe with an opening at the upper end, and is electrically connected to the control unit 2. The heating element is configured to convert electrical energy into thermal energy and heat the medicinal rod part plugged into the interior thereof, and the heating temperature of the heating element is 150°C to 250°C.
[0029] The heating element includes: a heating tank 11, a heating element 12, a heat-insulating layer 13 and a heating shell 14. The heating tank 11 is a pipe with an opening at the upper end, and the heating tank 11 includes a heat-conducting metal material. The heating element 12 is electrically connected to the control unit 2, and the heating element 12 is fixed on the outer wall of the heating tank 11. The heating element 12 is configured to convert electrical energy into heat energy and transmit it to the heating tank 11. The outer side of the heating element 12 is coated with a heat-insulating layer 13. The heating shell 14 is a pipe, and the heating tank 11, the heating element 12 and the heat-insulating layer 13 are arranged in the heating shell 14, and a through hole is arranged at one end of the heating shell 14, and the through hole is adapted to the opening of the heating tank 11, and the medicinal rod passes through the through hole and is plugged into the heating tank 11.
[0030] like Figure 3 and Figure 4 As shown, the heating element further includes a temperature sensor 15 , which is fixed to the outer wall of the heating tank 11 , and the temperature sensor 15 is also electrically connected to the control unit 2 .
[0031] The opening of the heating groove 11 is circular, and the opening diameter of the heating groove 11 is 2 cm to 5 cm; the inner depth of the heating groove 11 is 3 cm to 10 cm.
[0032] The heating tank 11 can be made of stainless steel, etc. The heating tank 11 is a round tube with one end open. For example, the inner diameter of the heating tank 11 is 2 cm, 3 cm or 5 cm, and the depth of the heating tank 11 is 3 cm, 5 cm or 10 cm. The heating tank 11 and the medicinal massage stick are clearance-matched, and there is a clearance of less than or equal to 2 mm between the outer wall of the medicinal massage stick and the inner wall of the heating tank 11.
[0033] like Figure 5 As shown, a high temperature resistant annular elastic member 16 is fixed at the port of the heating groove 11. The high temperature resistant annular elastic member 16 can be high temperature resistant silicone. The inner diameter of the high temperature resistant annular elastic member 16 is adapted to the diameter of the medicinal massage stick. The inner ring of the high temperature resistant annular elastic member 16 has an interference fit with the medicinal massage stick, that is, the medicinal massage stick can be plugged into the heating groove 11 through the high temperature resistant annular elastic member 16. The high temperature resistant annular elastic member 16 can reduce the temperature loss in the heating groove 11, and can also make a uniform gap between the end of the medicinal massage stick and the inner wall of the heating groove 11, which can further improve the uniformity of heating and avoid carbonization caused by direct and long-term pressing of the medicinal massage stick and the inner wall of the heating groove 11.
[0034] The heating element 12 may be an annular heating resistor, and the heating element 12 contacts the heating groove 11 , so that the heat generated by the heating element 12 can be transferred to the heating groove 11 .

[0036] The heat-insulating cotton 131 is filled between the heat-insulating water tank 132 and the heating shell 14 and between the heating tank 11 and the heat-insulating water tank 132. The heat-insulating water tank 132 can effectively reduce the speed and efficiency of heat transfer from the heating element 12 to the heating shell 14, ensuring that the heating shell 14 is kept at a low temperature to avoid burns.

[0039] The power control circuit includes a thyristor or a solid-state relay, which is electrically connected to the microprocessor. The power control circuit is configured to receive a control signal from the microprocessor and output pulse electricity to the heating element 12.
[0040] The microprocessor can send a control signal to the power control circuit. The control signal is a pulse signal, such as a square wave signal. That is, after the thyristor or solid-state relay receives the control signal, it outputs pulse electricity to the heating element 12, such as a square wave current. By controlling the frequency of the square wave current and the duration of the low level (voltage is zero), the heating power of the heating element 12 can be controlled.
[0041] A current regulator may also be provided in the circuit between the thyristor or solid relay and the heating element 12, and a control end of the current regulator is electrically connected to the microprocessor.
