After a period of use, the oil smoke will adhere to the surface of the resistance wire. In addition, the high heating temperature can easily cause the oil smoke to carbonize, and finally cause voltage breakdown, burning the resistance wire. The product has a short service life and needs to be replaced frequently. In addition, the surface load of the existing resistance wire is high and it is easy to burn out. Summary of the invention

[0020] like Figures 1 to 4 As shown, a heat-conducting structure of a combustion chamber heater of a moxibustion instrument comprises a baffle 1, a heating tube 2 is installed on the baffle 1, the surface of the heating tube 2 is made of metal, a spiral heat sink 3 is installed on the heating tube 2, the spiral heat sink 3 is provided with a through hole 321, the heating tube 2 is installed in the through hole 321, the spiral heat sink 3 is made of metal, and a spiral gas flow channel is formed between the spiral heat sink 3 and the heating tube 2; a flange is provided on the baffle 1, the flange is integrally formed with the baffle 1, a thermocouple 4 is installed on the baffle 1, a thermocouple detection hole 322 is provided on the spiral heat sink 3, the thermocouple 4 is installed in the thermocouple detection hole 322, and the surface of the spiral heat sink 3 is provided with grooves and protrusions for increasing the heat dissipation area.

[0021] Working principle of this utility model: This product is installed in the combustion chamber of the moxibustion instrument. Figure 1 and Figure 3 As shown, the interface of the outer cover 100 matched with the product is connected to the flange of the product and sealed, and the heating tube 2 adopts 4 pieces and realizes the series electrical connection. Figure 3 The heating tube 2 starts heating, and the heat is transferred to the spiral heat sink 3. When the temperature rises to 700°C, the moxibustion gas enters the right side of the spiral heat sink 3 from the inlet on the outer cover 100. The moxibustion gas passes through Figure 1The spiral gas flow channel indicated by the middle arrow reaches the left side of the spiral heat sink 3 and receives a high-temperature treatment of 700°C in the spiral gas flow channel. Since the spiral heat sink 3 has both a heating effect on the moxibustion gas and a guiding effect of the spiral gas flow channel, the moxibustion gas can be fully and evenly heated, with a large heat exchange area, high heat treatment efficiency, and good heat uniformity of the moxibustion gas. Then the moxibustion gas flows from the left side of the spiral heat sink 3 through the outlet on the outer cover 100 to the next processing unit of the moxibustion instrument. The grooves and protrusions on the surface of the spiral heat sink 3 are a technical solution commonly used in the prior art to increase the heat exchange area, which can effectively improve the heat treatment effect. The spiral gas flow channel is the core structure of the present invention. The spiral gas flow channel spirals from the right side of the spiral heat sink 3 to the left side of the spiral heat sink 3. Figure 1 As indicated by the arrows in the figure (the arrow portion in the middle section of the spiral heat sink 3 is omitted), the moxibustion gas can be effectively heat treated in the spiral gas flow channel.

[0022] In this embodiment, the total power of the heating tube is 2000W and the temperature is 700℃. Due to the presence of the spiral heat sink 3, the heat dissipation efficiency of the heating tube is effectively improved, and the surface load can be effectively reduced. Therefore, under the same surface load, the power of the heating tube is greater than that of existing products, and the temperature is higher. Since the moxibustion gas and the resistance wire are isolated from the surface metal of the heating tube, the oil smoke in the moxibustion gas is not easy to carbonize. Even if it is carbonized, it has no safety impact on the resistance wire in the heating tube, and there will be no voltage breakdown, thereby burning the heating tube 2. The service life of the product is effectively extended and does not require frequent replacement. At the same time, flange connection is adopted, and when the product needs to be replaced, the operation is convenient.

[0023] In addition to the above embodiments, in the present invention, the spiral heat sink 3 is replaced with a ceramic material, and the surface of the heating tube is replaced with a ceramic material. The product will have better corrosion resistance, and at the same time, the insulation of the heating tube is higher, the product is safer, and electrical breakdown is prevented.

[0024] In addition to the above-mentioned embodiments, other undescribed implementation methods should also be within the scope of protection of the present utility model. The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Technicians in the technical field to which the present utility model belongs may make various modifications or supplements to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the present utility model or exceed the scope defined by the attached claims.
