Background technique

Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to the ability to absorb, decompose or transform various air pollutants. At present, most household air purifiers adopt adsorption type, and adsorption air purifiers are generally the main Capture particles through the following four methods: direct interception, inertial collision, Brownian diffusion mechanism, and screening effect. It has a good effect on collecting fine particles but has large wind resistance. In order to obtain high purification efficiency, the resistance of the filter screen is relatively large, and the filter screen needs Densification leads to a reduced lifespan and requires periodic replacement.

However, the filter elements of existing air purifiers are mostly fixed by nuts or buckles, and the replacement is slow. The sliding filter element is prone to offset. After the offset, the external wind easily enters from the gap around the filter element, which easily affects the filtering effect. . In addition, some hairs are easy to be inhaled during the operation of the fan, and the inhaled hair is easy to adhere to the filter element, thereby affecting the air purification and reducing the purification efficiency. When the fan stops working, the hair adsorbed on the filter element due to negative pressure will fall off. If it is not cleaned in time, when the fan works again, the hair will be sucked up again, which will affect the air purification again.
