Description

TECHNICAL FIELD

[0002] An air purifier, also known as an air cleaner or an air freshener, is a product capable of adsorbing, decomposing or converting various air pollutants and effectively improving air cleanliness, and is generally used for removing indoor air pollutants.

[0003] For users who raise pets such as cats and dogs at home, in addition to purifying pollutants in the air, the air purifier also needs to be able to remove the odor of pets and the hair of pets in the air, but the filter element of the conventional air purifier will be contaminated with a lot of hair after long-term work in such an environment, which will not only cause the air purification effect and efficiency to be poor, but also increase the difficulty of cleaning the filter element and consume more manpower. Since the hair is not a small particulate matter like air pollutants, when there are pets in the use environment, the air purifier for pets will be equipped with a filter screen in front of the filter element to prevent the hair from directly entangling with the filter element.

[0004] However, when the conventional filter screen is disassembled, the top or both ends of the purifier need to be completely disassembled, the filter screen is pulled out from one end, and then a new filter screen is inserted, which is inconvenient to replace, and the hair on the filter screen is easily scraped off the filter screen during the pulling-out process, resulting in poor purification effect, and thus needs to be improved.

[0037] The winding roller 2 and the unwinding roller 3 make the filter cloth 4 adhere to the outside of the arc-shaped barrier net 12, in the working process of the purifier, pet hair and large-particle dust in the air are first blocked by the filter cloth 4, and are adsorbed on the outside of the filter cloth 4 under the action of static electricity. Small-particle dust is blocked by the filter core 11 after penetrating through the filter cloth 4, double-layer filtration can improve the service life of the filter core 11 and the air purification effect. After a period of use, the filter cloth 4 needs to be cleaned, the user starts the driving assembly 6, the driving assembly 6 drives the winding roller 2 and the unwinding roller 3 to synchronously rotate clockwise, the winding and unwinding are performed, the filter cloth 4 covering the arc-shaped barrier net 12 is gradually wound on the winding roller 2, the driving assembly 6 synchronously drives the self-cleaning assembly 5 to clean the dust and hair on the filter cloth 4 in the moving process of the filter cloth 4, and the filter cloth 4 originally wound on the unwinding roller 3 temporarily covers the arc-shaped barrier net 12, the purifier keeps working in the cleaning process, and does not need to be stopped to cause interruption of purification. After winding is completed, the driving assembly 6 drives the winding roller 2 and the unwinding roller 3 to synchronously rotate counterclockwise, the filter cloth 4 returns to the original position, and the self-cleaning assembly 5 cleans the filter cloth 4 again in the reversing process, thereby improving the cleaning effect. Automatic cleaning is realized, manual frequent disassembly and assembly of the filter net for cleaning are not needed, and the cleaning process is simplified.

[0038] Referring to Figure 2 and Figure 3The self-cleaning assembly 5 comprises a dust collecting box 51 movably arranged on the inner side wall of the purifier body 1, and a slot is formed on the side wall of the dust collecting box 51 near the arc-shaped barrier net 12 for the filter cloth 4 to pass through. The winding roller 2 is arranged in the dust collecting box 51. Due to the limitation of the space in the purifier body 1, two deflection rollers are further arranged in the dust collecting box 51, and the filter cloth 4 passes through the two deflection rollers in sequence and is wound on the winding roller 2. When the winding roller 2 winds the filter cloth 4, the two deflection rollers rotate under the action of friction, guide the movement track of the filter cloth 4, and reduce the friction between the filter cloth 4 and other components to reduce the service life.

[0039] A cleaning roller 52 is arranged between the two deflection rollers, and the outer side of the cleaning roller 52 is made of felt. The friction between the felt and the outer side of the filter cloth 4 can remove the hair and dust. Four first rotating shafts 53 are arranged at the top of the dust collecting box 51, and the winding roller 2, the cleaning roller 52 and the two deflection rollers are rotatably connected to the dust collecting box 51 through the first rotating shafts 53.
