[0026] like Figures 1 to 6As shown, a special heater for the combustion chamber of a moxibustion instrument comprises a baffle 1, a flange is provided on the baffle 1, the flange and the baffle 1 are made in one piece, a heating tube 2 is installed on the baffle 1, the surface of the heating tube 2 is made of metal material, a heat dissipation guide plate 30 is mounted on the heating tube 2, the heat dissipation guide plate 30 is made of metal material, a notch 303 is provided on the heat dissipation guide plate 30, the heat dissipation guide plates 30 are arranged at equal intervals between adjacent ones, and the adjacent ones are staggered 180 degrees according to the position of the notch 303. ° setting, the heat dissipation guide plate 30 is provided with a heat dissipation guide plate through hole 301, the heating tube 2 is arranged in the heat dissipation guide plate through hole 301, the baffle 1 is installed with a thermocouple 4, the heat dissipation guide plate 30 is provided with a thermocouple detection hole 302, the thermocouple 4 is inserted and installed in the thermocouple detection hole 302, the channel formed by the notch 303, the heating tube 2, the thermocouple 4 and the heat dissipation guide plate 30 forms a gas flow channel, and the gas flow channel runs through the heat dissipation guide plate 30 at both ends.

[0027] Working principle of this utility model: This product is installed in the combustion chamber of the moxibustion instrument. Figure 6 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 is composed of 4 pieces and electrically connected in series. Figure 4 It reflects the layout structure and wiring method of the heating pipe. Figure 5 This reflects that the heating tube 2 has a common internal structure on the market.

[0028] The heating tube 2 starts heating, and the heat is transferred to the heat dissipation guide plate 30. When the temperature rises to 700°C, the moxibustion gas enters the right side of the heat dissipation guide plate 30 from the inlet on the outer cover 100. The moxibustion gas passes through Figure 6 The gas flow channel indicated by the middle arrow reaches the left side of the leftmost heat dissipation guide plate 30 and receives a high-temperature treatment of 700°C in the gas flow channel. Since the heat dissipation guide plate 30 has a heating effect on the moxibustion gas, and the notches 303 of adjacent heat dissipation guide plates 30 are offset by 180°, the heat dissipation guide plate 30 has a meandering guide effect, which can fully and evenly heat the moxibustion gas. The heat exchange area is large, the heat treatment efficiency is high, and the heat uniformity of the moxibustion gas is good. Then the moxibustion gas flows from the left side of the leftmost heat dissipation guide plate 30 through the outlet on the outer cover 100 to the next processing unit of the moxibustion instrument.

[0029] In this embodiment, the total power of the heating tube is 2000W and the temperature is 700℃. Due to the presence of the heat dissipation guide plate 30, the heat dissipation efficiency of the heating tube is effectively improved, the surface load can be effectively reduced, and the surface load of the resistance wire is not high and will not burn out. Therefore, under the same surface load, the power of the heating tube is greater than that of existing products, and the heat treatment temperature of the product can be 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 has no safety impact on the resistance wire in the heating tube after carbonization, and there will be no voltage breakdown to burn the heating tube. 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.

[0030] In addition to the above embodiments, in the present invention, the heat dissipation guide plate 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. At the same time, the insulation of the heating tube is higher, the product is safer, and electrical breakdown is eliminated.

[0031] In addition, it is particularly noted that the notch described in the present invention includes a structure formed by punching to enable gas to flow through the heat dissipation guide plate 30, that is, a punching structure in the usual sense.

[0032] In addition to the above-mentioned embodiments, other undescribed implementation methods should also be within the scope of protection of the present utility model.
