EASY-INSTALL FAN FILTERING MECHANISM

WIPO Patent Application WO/2021/253266

A1

Disclosed in the present utility model is an easy-install fan filtering mechanism, comprising a body. A fan is provided at the middle position of the interior of the body. A fan inlet mesh is provided on the upper surface of the fan. The fan inlet mesh is fixedly connected to the body by means of screwing. A main filter mesh is provided on the lower surface of the body. A main filter mesh fixing frame is provided on the outer surface of the main filter mesh. A placement groove is formed at a position where the main filter mesh fixing frame and the main filter mesh are connected. The design of a press plate at a position where a main filter mesh protection cover and the body are connected avoids uneasy detaching during cleaning due to excessive dirt on the fan filtering mechanism after being used for a long period of time and tedious operations during engagement installation. The press plate can be manually turned to place the main filter mesh at the bottom of the body. The press plate automatically and tightly presses down under the action of deformation of a torsion spring on an outer surface of a connection shaft. During a tight press process, a projecting elongated block are tightly engaged in the interior of a recess, such that the main filter mesh is tightly fixed to the body.
