Description

Technical Field

[0001] The invention relates to the technical field of air treatment, and in particular to an air treatment device for a dusty environment. Background Art

[0002] In industrial production, waste gas containing dust is often emitted into the air. Dust is very harmful to the human respiratory tract. As people pay more and more attention to air quality, various air quality treatment instruments emerge in an endless stream. For example, air filtration devices are widely used in indoor air purification, industrial emission control, clean rooms and other fields. Air filtration devices can remove particulate matter, bacteria, viruses and harmful gases in the air, improve air quality and protect human health.

[0003] The air filter device generates suction through a small fan in the intake duct, so that the outside air is sucked into the intake duct, and then the incoming air is filtered through the filter layer. The air filtering method is to use a filter to filter out dust in the air, and the filtered air is discharged through the fan of the exhaust duct.

[0004] In the prior art, the filter layer for filtering air is generally fixed inside the device. After the device is used for a long time, the surface of the filter layer absorbs a large amount of dust, and the device needs to be shut down before it can be cleaned, which affects the working efficiency. If it is not cleaned, the long-term accumulated dust will not only affect the filtering efficiency, but also may cause physical damage to the filter layer, such as wear and blockage.

Then the filter cartridge drives the filtered dust to rotate, so that the cleaning roller can drive the dust on the filtering surface of the filter cartridge into the inside of the collection box, so that the filter cartridge can be cleaned in real time while filtering, avoiding the accumulation of a large amount of dust on the filtering surface of the filter cartridge, causing blockage, thereby affecting the use of the device.

[0016] 2. The incomplete gear will mesh with the rack when it rotates, so it will drive the filter cartridge to slide down along the inner wall of the filter chamber. After that, all the gears of the incomplete gear will pass over the inner wall of the tooth groove of the rack, and then the incomplete gear will no longer contact the rack. Then the spring will reset through elastic force, so that the incomplete gear drives the cleaning roller and the filter cartridge to reset. During the resetting process, the filter cartridge will vibrate, so that the dust adsorbed on the filter surface of the filter cartridge will vibrate and fall off, thereby achieving the function of cleaning the filter cartridge and further improving the cleaning effect of the filter cartridge.

[0017] 3. The slider drives the piston to slide upward along the inner wall of the inner cavity, which will cause the air inlet pipe to absorb the external gas into the inner cavity. When the slider slides downward along the inner wall of the second slide groove, the piston will squeeze the gas to make it enter the water tank. Then the water tank will supply water to the diversion pipe, and then spray it through the atomizing nozzle, so as to clean the surface of the cleaning roller. At the same time, the dust is absorbed by the water mist and falls into the collection box, so as to achieve the effect of cleaning and reducing dust on the cleaning roller.
