Fresh air purifier

Abstract

The invention discloses a fresh air purifier comprising a housing enclosing a cavity. The housing is provided with an air inlet and a fresh air outlet. The cavity is internally provided with an air filtering and purifying component. The air filtering and purifying component divides the cavity into an inflow cavity and a fresh air cavity. The wall of the inflow cavity is provided with an inflow hole. The wall of the fresh air cavity is provided with another fresh air outlet. The filter face of the air filtering and purifying component and the air flow section make a preset included angle; the air filtering and purifying component is peripherally hermetically connected with the inner wall of the cavity. The filter face of the air filtering and purifying component and the air flow section make the preset included angle, in other words, the filter face of the air filtering and purifying component is not perpendicular to air flow, a certain included angle is formed, and flow area of the filter area is effectively increased at the premise of not increasing the size of the existing apparatus; similarly, at the premise of ensuring same flow quantities, air resistance can be correspondingly reduced, and functional parameters of the fresh air purifier are improved.

Description

technical field [0001] The invention relates to the technical field of gas purification equipment, in particular to a fresh air purifier. Background technique [0002] The fresh air purifier is an air-conditioning device that provides fresh air. Its main working principle is to process the outdoor or indoor air through different levels of dust removal, filtration and disinfection, and then send it to the room through a fan. [0003] Whether it is to send outdoor air filtration and purification to the room, or to realize the filtration and purification cycle of indoor air, the structure of the fresh air purifier is roughly the same. Generally, the fresh air purifier includes a housing that encloses a cavity. The housing is provided with an air inlet and a fresh air outlet. An air filter and purification assembly is arranged inside the housing. The air filter and purification assembly separates the cavity into an air intake chamber and an air intake chamber. In the fresh air ...

AI Technical Summary

Problems solved by technology

[0007] In addition, in the prior art, the air filter and purification assembly is fixed inside the housing through fixing parts, which takes time and effort to install; and the air filter and purification assembly needs to be replaced after a period of use, otherwise it will affect the gas purification effect. In the prior art, the air filter and purification assembly It is also troublesome to replace and maintain

[0008] Furthermore, the existing household fresh air purifiers are generally equipped with axial flow fans, and the space occupied by the axial flow fans needs to be provided independently. Therefore, the existing household fresh air purifiers are generally large in size.
