Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a filter element component and an air purifier with a sealing structure. Background Art

[0002] The core performance component of a filter-type air purifier is the filter element. The filtering efficiency of the filter element directly determines the amount of clean air in the whole machine. At the same time, if a high-performance filter element does not have a good sealing design with the panel in the air duct, it will cause poor performance of the whole machine. Therefore, in order to realize the true effect of the filter element and reduce the degree of unreasonable utilization, the sealing design of the filter element and the air duct panel is particularly important.

[0003] After searching, the authorization announcement number is CN206934940U, which discloses a new air purifier, which is vertically arranged, and has air inlets on the left, right and rear of the lower part. Each air inlet is as large as possible, and the wall surface of the air purifier where the air inlet is opened is grid-shaped; a cylindrical filter is arranged at the lower part of the air purifier, and the filter is also vertically arranged. The air entering the air purifier from the air inlet passes through the wall surface of the filter and enters the interior of the filter, and then moves upward and is discharged through the air outlet at the top of the air purifier under the action of the impeller, wherein the top of the cylindrical filter is sealed with the air purifier body, and the bottom thereof is also sealed with the base of the air purifier, thereby ensuring that the outside air must pass through the wall surface of the filter before entering the interior of the filter and being discharged from the air outlet.

[0004] The above device has the following defects. Generally, air enters the filter element assembly of the air purifier from the air inlet for filtration, and the filtered air is then sent out through the air outlet for circulation filtration. Therefore, the sealing performance of the filter element assembly is required to be high. The conventional filter element assembly achieves the sealing effect by sticking a sealing sticker on the edge of the filter element assembly. After using this sealing sticker for a period of time, the part where the sealing sticker is glued is prone to aging, which reduces the sealing performance of the filter element assembly, and then causes air leakage at the edge of the filter element assembly, thereby reducing the air filtration efficiency. Improvements are made for this purpose. Utility Model Content
