Household air purifier

Abstract

The invention belongs to a household air purifier. The household air purifier consists of a machine body, a weak current plate and a strong current plate, wherein an upper centrifugal wind wheel and alower centrifugal wind wheel are separately driven by an upper motor and a lower motor; an Archimedean spiral upper partition board is arranged at the upper part in the rear space of the machine bodyaround the upper centrifugal wind wheel; space between the Archimedean spiral upper partition board and the periphery of the upper centrifugal wind wheel forms an Archimedean spiral upper air duct; an upper air outlet of the Archimedean spiral upper air duct is located at the upper end of the machine body; an Archimedean spiral lower partition board is arranged at the lower part in the rear spaceof the machine body around the lower centrifugal wind wheel; space between the Archimedean spiral lower partition board and the periphery of the lower centrifugal wind wheel forms an Archimedean spiral lower air duct; and a lower air outlet of the Archimedean spiral lower air duct is located at the side end of the machine body. The household air purifier has the advantages of small size, small air losses, large air output, reasonable filter design, high purifying efficiency, no noise, convenient and rapid filter material change, smooth air supply, high purifying efficiency and great use effect.

Description

technical field [0001] The invention belongs to a household air purifier. Background technique [0002] At present, China's outdoor ambient air quality is becoming more and more serious. With the development of industry and dense population, the emission of harmful gases has also increased significantly. The large increase of harmful gases will cause smog and endanger human health. Nowadays, interior decoration materials are more and more abundant. However, most of the decoration materials contain high concentrations of volatile and harmful chemical substances, which are also harmful to human health. Indoor air quality is deteriorating day by day, which has become a problem that needs urgent improvement. [0003] At present, there are many types of household air purifiers, most of which have the disadvantages of small amount of purified air, unreasonable filter design, low purification efficiency, high noise, backward connection methods, time-consuming and laborious replace...

AI Technical Summary

Problems solved by technology

The four filters of this patent form a dead angle for air outlet purification, and will generate swirling wind resistance, which will cause the fan blades to generate greater noise. The filter design is unreasonable, the purification efficiency is low, and the connection method is backward, and it takes time and effort to replace the filter material.
