Description

Technical Field

[0001] The present invention relates to the technical field of air purifiers, in particular to a pet air purifier. Background Art

[0002] Traditional pet air purifiers use fans to absorb dust and hair directly into the filter element for air filtration. A large amount of dust and hair remain on the filter element for a long time and cannot be cleaned. Especially when there are pets at home, a large amount of hair is absorbed on the filter element. If it is not cleaned in time, the purification efficiency of the purifier will be affected over time. At the same time, it is easy to breed bacteria, and the filter element needs to be replaced in time, affecting the user experience.

[0003] The invention patent with publication number CN118669916A discloses an intelligent air purifier for sucking pet hair, comprising a body with an oblong cross-section, a front air inlet, a rear air inlet and an air outlet arranged on the top of the body, an air purification system, an air suction system and a hair self-cleaning system are also arranged in the body, wherein the front air inlet comprises an air inlet cover and a pushing mechanism connected to the air inlet cover, the rear air inlet comprises an air inlet seat and an adjusting mechanism connected to the air inlet seat, the air inlet cover moves along the Y-axis direction of the body through the pushing mechanism, and the air inlet seat rotates clockwise or counterclockwise along the body through the adjusting mechanism; the air purification system comprises a plurality of filter elements and a fixed A mounting seat is fixed at the bottom of the filter element, and the mounting seat is provided with a mounting shaft. The mounting shaft is connected to the air outlet after passing through the filter element, and a locking piece is provided at the connection between the mounting shaft and the air outlet, wherein an air supply duct for connecting to an air suction system is provided at the bottom of the mounting seat, and the air suction system includes a group of turbine suction fans, and the turbine suction fans are connected to the air inlet cover duct, and the turbine suction fans are symmetrically arranged inside the fuselage; the hair self-cleaning system includes a hair scraper, which is arranged in the air outlet, and the hair scraper is coaxially sleeved on the filter element, and the hair scraper is connected to the fuselage, and a lifting structure is provided at the connection between the hair scraper and the fuselage, and the hair scraper moves along the axial direction of the filter element through the lifting structure. The prior art uses an air suction system to suck dust and hair into the body and discharges them after being filtered by the filter element, thereby purifying the air. When the dust and hair on the filter element need to be cleaned, the scraper is driven by the lifting structure to move along the axial direction of the filter element to scrape off the dust and hair on the filter element. The defect of the prior art is that when the scraper is driven by the lifting structure to scrape the filter element, the dust and hair on the filter element are easily attached to the scraper. When the scraper repeatedly scrapes the filter element, the dust and hair on the scraper will repeatedly attach to the filter element, resulting in a very unsatisfactory cleaning effect.

[0004] Therefore, there is still room for improvement in the prior art. Summary of the invention

[0005] In order to solve the problems of the prior art, the present invention provides a pet air purifier.
