The inner wall of the air supply pipe 3 is provided with a threaded groove, and the threaded end 45 is threadedly connected to the threaded groove on the inner wall of the air supply pipe 3. A filter element 46 is inserted into the inner wall of the filter tube 41, and a blocking ring 47 is fixedly connected to the inner wall of the air supply pipe 3. A push ring 48 is slidably connected to the inner wall of the filter tube 41, and a spring 49 is fixedly connected to the side of the push ring 48 corresponding to the inner wall of the filter tube 41. A shielding component 44 is provided on the surface of the air supply pipe 3, and an auxiliary component 43 is provided on the surface of the filter tube 41.

[0023] In this embodiment: when in use, the threaded end 45 of the filter tube 41 can be connected to the threaded groove on the inner wall of the air supply pipe 3, and then the blocking ring 47 squeezes the filter element 46, and the filter element 46 is pushed into the filter tube 41, and then the push ring 48 squeezes the spring 49. The filter element 46 can intercept and adsorb impurities in the gas. During subsequent cleaning, the filter tube 41 is removed from the air supply pipe 3, and the spring 49 can drive the push ring 48 to push out the filter element 46 for easy cleaning.

[0024] Specifically, the auxiliary component 43 includes a handle 431. There are two handles 431. The two handles 431 are respectively arranged on both sides of the filter tube 41. Two grooves 433 are provided on the surface of the filter tube 41. The inner wall of the groove 433 is fixedly connected to the fixed rod 432. The handle 431 is rotatably connected to the surface of the fixed rod 432.
