Description

Technical Field

[0001] The utility model relates to a filter screen structure of an air purifier, in particular to an inner side filter screen structure of an air purifier. Background Art

[0002] The filter is a key structural component of the air purifier, which is used for dust prevention and air purification, etc. Therefore, regular cleaning and maintenance of the filter is very important for the air purifier. The cleanliness of the air purifier filter directly affects the cleanliness of the indoor air.

[0003] At present, the mesh structure of the existing air purifier filter structure is not well fixed to the fixed structure inside the appliance during use, resulting in poor filtering effect. In addition, during the connection process between the existing mesh structure and the filter mesh body, the inner side filter structure of the air purifier and the fixed structure inside the appliance are prone to loose connection and inconvenient disassembly, and the circular air filter mesh structure is partially broken or disconnected as a whole during the later use. This further reduces the service life of the processed product and the quality of the product. Utility Model Content

[0004] The utility model aims to provide an inner side filter screen structure of an air purifier, so as to solve the problem that the inner side filter screen structure of the air purifier is firm to use and not easy to break.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an inner side filter screen structure of an air purifier, including a grid body structure and a filter screen body covered on the grid body structure, the grid body structure includes a trapezoidal general connector, a built-in support frame assembly arranged in the general connector and a positioning connection assembly arranged outside the general connector, the general connector and the built-in support frame assembly are integrally formed by injection molding, and a plurality of groups of inner loop grooves are arranged in the general connector, the depth of the inner loop grooves is 0.5cm-1cm, and a plurality of inner stoppers are arranged at intervals in the inner loop grooves.

[0006] The positioning connection assembly comprises a middle plug-in block arranged at the upper end of the overall connector and a group of buckle assembly structures arranged outside the middle plug-in block.

[0007] The built-in support frame assembly is rectangular; a middle section inner ring groove is provided in each built-in support frame assembly, and the middle section inner ring groove is connected with the inner ring groove.

[0008] The buckle assembly structure comprises a buckle connection end designed as a whole with the overall connection body and an external hook body arranged on the upper part of the buckle connection end.

[0009] The beneficial effects of the utility model are as follows: the inner filter screen structure of the air purifier is provided with multiple groups of inner loop grooves in the general connector and multiple inner stoppers are provided at intervals in the inner loop grooves. This is conducive to firmly fixing the mesh structure and the built-in fixing structure of the air purifier. The connection strength between the mesh frame structure and the filter screen body is improved. This can effectively help the staff to improve the product quality and reduce the scrap rate.
