Abstract

The invention discloses an air filtering hood for an electric fan. The air filtering hood for the electric fan comprises a filtering hood body; an annular shell is arranged on the filtering hood bodyand provided with a framework and a screen; the framework comprises a connection center and four connection rods; one ends of the connection rods are arranged on the shell, and the other ends of the connection rods are arranged at the connection center; the screen covers the outer surface of the framework; and a filtering layer is arranged in the framework. The air filtering hood can be directly used on the household electric fan, so that the air purification function of the electric fan is added, the air filtering hood is simple in structure and detachable, and the filtering layer is convenient to replace.

Description

technical field [0001] The invention relates to the field of air filtration, in particular to an air filter cover for an electric fan. Background technique [0002] At present, the air purifiers on the market are integrated with many components, and they are generally an integrated device that is relatively difficult to disassemble, and the price is expensive, usually several thousand yuan or more. [0003] As a common household appliance, fan is simple in structure and cheap in price. Almost every ordinary family is equipped with fan to dissipate heat. However, the fan does not have an air purification function. [0004] However, with the aggravation of air pollution, problems such as eliminating smog have become concerns among the general population of the society, especially the air purification of indoor air. However, the various air purifiers on the market are not affordable by many ordinary wage earners. Contents of the invention [0005] The purpose of the presen...
