[0021] The rotating mechanism 2 includes a first support plate 201 fixedly connected to the upper end of the filter cartridge housing 1, an air inlet 202 is provided in the center of the first support plate 201, a first groove 203 is provided inside the outer side of the first support plate 201, the outer side surface of the first groove 203 is in contact with the inner side surface of the first support ring 207, and the width of the first groove 203 is greater than the width of the first hole 204, so that the first support ring 207 does not shake when rotating inside the first groove 203, and the first support ring 207 does not move outside the first hole 204, the middle and lower part of the first groove 203 is connected to the first hole 204, and second grooves 205 are provided below both sides of the first groove 203, and first balls 206 are provided inside the second groove 205, and a plurality of first balls 206 are provided, the depth of the second groove 205 is greater than the radius of the first ball 206, and the top view structure of the second groove 205 is circular. The first ball 206 is prevented from moving out of the inner side of the second groove 205. A first support ring 207 is provided on the inner side of the first groove 203. A second support ring 208 is fixedly connected to the bottom of the first support ring 207. A second ball 209 is provided above the second support ring 208. There are multiple second balls 209. The second support ring 208 is nested in the inner side of the first hole 204. The outer sides of adjacent first balls 206 fit together, and the diameter of the first ball 206 is greater than the depth of the second groove 205, so that the first ball 206 does not shake when rotating inside the second groove 205, and the first ball 206 can support the first support ring 207. The outer side surface of the second ball 209 fits with the upper side surface of the first support ring 207, and the outer side surface of the second ball 209 fits with the inner side surface of the first groove 203, so that the second ball 209 can support the first support ring 207.

[0022] The pushing mechanism 3 includes a support cylinder 301 fixedly connected to the lower end of the second support ring 208, the diameter of the hole on the inner side of the support cylinder 301 is larger than the diameter of the air inlet 202, a first baffle 302 is fixedly connected to the inner wall of the support cylinder 301, and a plurality of first baffles 302 are provided, and a second baffle 303 is fixedly connected to the outer wall of the support cylinder 301, and a plurality of second baffles 303 are provided. The central axis of the support cylinder 301 coincides with the central axis of the filter cartridge housing 1, and the appearance structure of the first baffle 302 is an inclined straight line, and the first baffle 302 is equidistantly arranged on the inner side of the support cylinder 301 in an annular manner, so that the airflow can drive the support cylinder 301 to rotate along the outer side surface of the first baffle 302, and the appearance structure of the second baffle 303 is an inclined straight line, and the second baffle 303 is equidistantly arranged on the outer side of the support cylinder 301 in an annular manner, and the inclination direction of the second baffle 303 is opposite to that of the first baffle 302, so that the airflow can push the support cylinder 301 to rotate along the second baffle 303.

[0023] When the air flow enters the inner side of the support tube 301 from the air inlet 202, the air flow is separated after contacting the first baffle 302, and the speed is reduced to achieve the effect of noise reduction. Since the appearance structure of the first baffle 302 is an inclined straight line, part of the air flow pushes the first baffle 302 to rotate, causing the second support ring 208 to rotate, so that the air flow is pushed in a spiral shape. The spirally rotating air flow is more stable and continuous, reducing irregular air flow vibration and disturbance, thereby reducing the generation of noise. Compared with the horizontal baffle diversion, the spirally rotating air flow is smoother and streamlined, which is conducive to reducing the formation of turbulence and vortex, thereby reducing noise. Since the appearance structure of the second baffle 303 is an inclined straight line, when the air flow moves to the position of the third baffle 4, it is reflected back to continue to push the second baffle 303 and the support tube 301 to rotate, making it easier to generate spirally rotating air flow.
