An air purification device with a front removable sterilizer

Abstract

The invention relates to an air cleaning device with a removable sterilizer arranged in the front. According to an existing air cleaning device, dedusting is performed before sterilization, and thus bacteria breed on a filtering screen. The air cleaning device comprises a shell and an air duct arranged in the shell. The air duct is formed by an air inlet, the sterilizer arranged in the front, the filtering screen arranged in the rear, a fan and an air outlet sequentially, and thus air is cleaned in the air duct in the sequence that sterilization is performed before dedusting, wherein the sterilizer is a single body capable of being removed from and mounted on the cleaning device. The air treatment step is changed into a mode that sterilization is performed before filtration from an original mode that filtration is performed before sterilization, air is sterilized before making contact with the filtering screen, and thus the sterilization effect of the air cleaning device on the indoor air is improved. While the sequence of sterilization and dedusting is changed, the structure of the sterilizer is changed, the sterilizer is improved to be the removable single body from an assembly type sterilizer with an inner cavity, and thus the sterilizer playing the sterilization function has the advantages of not only improving the sterilization effect but also being convenient to manufacture, install, maintain and replace.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air purification device with a sterilizer. Background technique [0002] Air purification devices are often used to purify indoor air, which can sterilize and remove dust from the air. The air purification device usually includes a housing and an air duct installed in the housing which is composed of a dust filter, a sterilizing element and a fan. The air sucked into the air duct by the fan passes through the dust filter and the sterilizing element in turn for dust removal and sterilization. . There are following defects in the air purification device in which the sterilizing element is formed in the inner cavity and placed behind the filter screen: 1. The air with bacteria and dust from the outside first passes through the dust filter screen, so that the bacteria in the air are attached to the filter screen, and it is not cleaned for a long time It will cause a large number of ...
