Description

Technical Field

[0001] This utility model belongs to the technical field of filtration and air purification devices, and more specifically, relates to a filter assembly and an air purifier. Background Technology

[0002] An air purifier (also known as an air cleaner or air freshener) is a device that treats air pollutants through physical or chemical means. It is mainly used to improve indoor air quality, and the filter is one of the essential components in the use of an air purifier.

[0003] In most existing air purifiers, the filter is installed near the air inlet. The filter removes suspended particles such as PM2.5, pollen, and dust from the air through materials such as HEPA filters, thus achieving preliminary air purification.

[0004] However, when the filter intercepts and filters impurities in the air, the impurities will adhere to one side of the filter and form a barrier layer on its surface. This barrier layer will cover the pores of the filter, causing the air to be obstructed when passing through the filter and affecting the normal filtration of the air. Utility Model Content

[0008] By setting the cleaning device, first start the motor to drive the screw to rotate, so that the screw drives the hole rod up and down, so that the hole rod drives the circular shaft and the gear up and down, under the meshing effect of the gear and the gear rod, the gear rotates in the moving process and drives the circular shaft to rotate, so that the circular shaft drives the glue cylinder to rotate, so that the glue cylinder adheres to the surface of the filter screen body up and down and rotates, and the adhered impurities are removed from the filter screen body, so that the accumulated impurities on the surface of the filter screen body are cleaned, and the blocking layer formed by the impurities covers the holes of the filter screen body, causing the air to be blocked when passing through the filter screen body, affecting the normal filtering of the filter screen body, and improving the cleaning convenience of the filter screen body.

[0009] According to the filter screen assembly of the first aspect of the utility model, the cleaning device further includes a bolt, wherein the bolt is threadedly connected with the inner wall of the circular shaft, and the glue cylinder is fixed by extrusion at the position of the bolt nut.

[0010] According to the filter screen assembly of the first aspect of the utility model, the cleaning device further includes a limiting block, wherein the limiting block is fixedly connected to the circular shaft, and the limiting block is limited by being clamped into the groove in the interior of the glue cylinder. By setting the limiting block, the limiting block can be clamped into the groove in the interior of the glue cylinder to limit the glue cylinder, reducing the self-rotation of the glue cylinder when being driven to rotate by the circular shaft.

[0011] According to the filter screen assembly of the first aspect of the utility model, the cleaning device further includes a positioning rod, wherein the positioning rod is fixedly connected to the frame of the filter screen body, and the positioning rod is positioned in the interior of the hole rod. By setting the positioning rod, the positioning rod can be positioned in the interior of the hole rod to reduce the rotation or shaking of the hole rod when being driven by the screw.

[0012] According to the filter screen assembly of the first aspect of the utility model, the cleaning device further includes a scraping assembly, the scraping assembly includes an L-shaped rod, wherein the L-shaped rod is fixedly connected to the hole rod; and a scraper, wherein the surface of the scraper is attached to the surface of the glue cylinder. By setting the scraping assembly, when the glue cylinder rotates, the scraper attached to the surface of the glue cylinder scrapes off the impurities adhered to the surface of the glue cylinder, achieving rapid impurity removal of the glue cylinder, reducing the adhesion of more impurities on the surface of the glue cylinder, covering the adhesive parts of the glue cylinder, affecting the adhesion of impurities, and further improving the cleaning effect of impurities.

[0013] According to the filter screen assembly, the material scraping assembly further comprises a baffle, wherein the baffle is fixed to one side of the L-shaped rod close to the scraper, and a cross section of the baffle is arc-shaped. The baffle can intercept the impurities scraped up, and reduce the situation that the impurities formed barrier layer covers the holes of the filter screen body, causes air to be blocked when passing through the filter screen body, and affects normal filtering of the filter screen body.
