[0018] The filter structure for the moxibustion instrument includes a middle-through ring-shaped flow guide cover 325, an air inlet 3252 is arranged on the inner wall of the flow guide cover 325, and a flow guide cover connecting portion 3256 is coaxially arranged on the outer wall; one side of the flow guide cover connecting portion 3256 protrudes outward, and the other side is recessed inward to form an annular groove; an air exhaust assembly 3254 is fixed to the outside of the flow guide cover connecting portion 3256, one side of the air exhaust assembly 3254 is provided with a through hole matched with the flow guide cover connecting portion 3256, and the airflow is guided to the other side by covering the air exhaust assembly with an air exhaust assembly cover 3255, and the other side exhausts the airflow by arranging an air outlet 3251;

[0019] A dry filter (not shown in the figure) is arranged on the flow guide cover connecting portion 3256, or between the air exhaust assembly cover 3255 and the air exhaust assembly 3254, or in the inner cavity of the flow guide cover 325. The dry filter mainly adopts a filter core matched with the shape of the corresponding installation position, such as a disposable polyurethane filter core and an activated carbon filter core. When embedded in the annular cavity of the flow guide cover connecting portion 3256, a circular filter core structure that can just cover the flow guide cover connecting portion 3256 is adopted to achieve the purpose of sufficient filtration.

[0020] The air exhaust assembly 3254 is connected with the socket 3271 on one side of the flow guide cavity 327 through a sliding slot structure on the side of the air exhaust assembly 3254, so that the flow guide cover 325 is inserted and mounted in the flow guide cavity 327 from the bottom of the middle shell 32, the top of the flow guide cover 325 is limited, the bottom of the flow guide cover 325 is elastically abutted on the annular boss on the bottom of the middle shell 32 through the limiting buckle 3253 to limit the bottom of the flow guide cover 325, after the flow guide cavity 327 is inserted and fixed, the inlet end of the air exhaust assembly 3254 corresponds to the outlet end of the flow guide cover 325, and the air exhaust port 3251 of the air exhaust assembly 3254 corresponds to the smoke exhaust port 322 on the middle shell 32; after the top and the bottom of the flow guide cover 325 are limited, the flow guide cover 325 is fastened in the middle shell 32 through a plurality of bolts. The filter assembly (not shown in the figure) arranged at the connection between the flow guide cover 325 and the air exhaust assembly 3254 or in the air exhaust assembly 3254 or at the air exhaust port 3251 can effectively filter the smoke and dust after the moxa stick 1 is burned, so that the purpose of purifying air is achieved. The air inlet 3252 of the flow guide cover 325 is communicated with the air inlet channel 452 through the inner cavity of the inner pot body 42, so that an air flow channel is formed, and the oxygen supply during the burning of the moxa stick 1 is ensured. The inner wall of the inner pot body 42 on the inner side of the air inlet channel 452 is communicated through a plurality of through holes (not marked in the figure) to slow down the pressure relief speed of the pot body. The smoke and dust after the moxa stick 1 is burned enters the flow guide cover 325 through the air inlet 3252 in sequence, enters the air exhaust assembly 3254 through the flow guide cover connection 3256, and is finally exhausted out of the shell of the moxibustion instrument through the air exhaust port 3251. Thus, the smoke and dust can be adsorbed on the filter element of the filter structure in the flow process. Moreover, a disposable replaceable filter element is adopted, which is convenient for later maintenance and cleaning, and the use cost is effectively reduced through large-scale manufacturing.
