Air inlet channel applied to fresh air purification system

Abstract

The invention discloses an air inlet channel applied to a fresh air purification system. The air inlet channel is arranged at an air inlet end of the fresh air purification system, and comprises an internal circulation air duct and a fresh air duct; an air inlet end of the internal circulation air duct communicates with indoor air, while an air inlet end of the fresh air duct communicates with external atmosphere; a switching mechanism for closing or opening the fresh air duct is arranged in the fresh air duct. The air inlet channel of the present invention enables the fresh air purification system to have two modes, namely internal circulation purification for removing smoke, particulates, dust and the like in indoor air as well as thermal insulation, and fresh air intake for oxygen enrichment, ventilation, odor removal, moisture removal, room temperature regulation and the like; by means of switching of the internal circulation purification and the fresh air intake, the working efficiency of the fresh air purification system can be improved, and the energy consumption is relatively low, especially obvious in winter; the switching mechanism is ingenious in design and convenient and fast to operate; furthermore, the air inlet channel is simple in overall structure, convenient to produce and manufacture, and low in cost.

Description

technical field [0001] The invention relates to an air inlet channel, in particular to an air inlet channel applied to a fresh air purification system. Background technique [0002] Traditional air purification generally uses air purifiers, which are also known as "air cleaners", air fresheners, and purifiers, which refer to the ability to absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, Odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), products that can effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building. [0003] There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA hig...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the air purifier is that it only circulates and purifies the indoor air, and the purification objects are smoke, particles, dust, etc. in the indoor air.

[0006] In the prior art, the air inlet channel is composed of various pipes and joints. The fixing of the pipes is cumbersome and the joints are intricate. The air inlet channel and the external atmosphere are in a smooth state, the air circulation mode is relatively simple, the purification method is fixed, the energy consumption is large, and the purification efficiency is low.
