Novel household sterilizing air filter

Abstract

The invention discloses a household sterilizing air filter and relates to a household sterilizing air filter in the air filter filed. A technical scheme is that the novel household sterilizing air filter comprises a cover plate with a gas outlet and a housing with a gas inlet, wherein a cylindrical filter element connected with the cover plate extends into a concave cavity of the housing; the cover plate is in threaded connection with the housing; the cylindrical filter element further comprises an inner filter layer, a middle filter layer and an outer filter layer, wherein the inner filter layer is an active carbon layer; and the middle filter layer is a polyvinylidene fluoride layer and the outer layer is a nano-silver particle sterilization layer. The novel household sterilizing air filter has the beneficial effects that the filter element adopts the cylindrical structure, so that contact area of the air and the filter element is increased; the filter element adopts the inner filter layer, the middle filter layer and the outer filter layer, the active carbon layer is used for adsorbing peculiar smell and poisonous gases in the air, and filtering part of the dust, the polyvinylidene fluoride layer is used for filtering most of the dust by virtue of small hole diameter, and the nano-silver particle sterilization layer is used for effectively improving sterilization performance of the filter element, and therefore, the filter element is good in fertilization effect and high in sterilization performance.

Description

technical field [0001] The invention relates to the field of air filters, in particular to a sterilizing air filter for household use.
