[0046] Working principle: when in use, fill the water tank 401 with tap water, close the threaded plug 407, then pull out the dust receiving drawer 104, fill the dust receiving drawer 104 with tap water until the water level is about one-third of the height, then slide the dust receiving drawer 104 filled with water into the dust receiving chamber 102, and then open the flip door 111;

[0047] The adjusting motor 303 is started, and the adjusting motor 303 drives the driving wheel 304 to rotate through the worm gear reducer. When the driving wheel 304 rotates, the driven wheel 306 is driven to rotate through the belt 307. The driven wheel 306 drives the air guide outer cylinder 301 to rotate through the supporting shaft 305, so as to achieve the angle adjustment of the air guide outer cylinder 301. After the angle adjustment of the air guide outer cylinder 301 is completed, the electromagnet 603 is started, and the electromagnet 603 is supplied with alternating current. The electromagnet 603 supplied with alternating current generates periodic rapid switching, so that the nickel block 607 is continuously attracted and released, and then the nickel block 607 periodically and rapidly pulls the elastic net 503 through the rubber block 604, so that the elastic net 503 and the sponge dust filter block 504 are continuously vibrated;

[0048] Then the water pump 402 is started, and the water pump 402 pumps tap water, so that the tap water first reaches the water pump 402 from the water tank 401, then enters the guide hose 403, and then the water flows into the distribution ring 404, and then is sprayed out from the atomizing nozzle 405 in the form of water mist;

[0049] Then the fan 302 is started, and the fan 302 pumps high-speed airflow. The airflow first enters the air inlet duct 108, then passes through the isolation grid plate 109 to enter the dust receiving chamber 102, and then passes through the protective net 502, the sponge dust filter block 504 and the elastic net 503. The dust in the air is intercepted by the sponge dust filter block 504, and the clean airflow enters the air guide hose 202, and then passes through the fan 302 to enter the air guide outer cylinder 301, and then the airflow passes through the air guide gap and is ejected from the inner wall of one end of the air guide outer cylinder 301, and then the airflow is ejected from one end of the air guide outer cylinder 301 to the other end along the elastic air guide lining 309. At this time, the high-speed airflow inside the elastic air guide lining 309 will generate negative pressure to attract air, so that the airflow flows together to the atomizing nozzle 405 at the other end, and at the same time takes away the water mist sprayed by the atomizing nozzle 405. The water mist is mixed with the air after being sprayed, so that the dust in the air is moistened and increased in weight, so that it is convenient to fall quickly, thereby achieving dust removal;

[0050] At the same time, the continuously vibrating sponge dust filter block 504 shakes off the trapped dust, causing the dust to fall into the water inside the dust receiving drawer 104, thereby preventing the dust from floating.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
