Household air purify device

Abstract

A domestic air purification device include a housing, the two ends of the shell are respectively provided with a bottom air inlet and a top air outlet, An air inlet fan is arranged in the bottom air inlet, an air outlet fan is arranged in the top air outlet, a purification chamber is arranged in the shell, the bottom air inlet and the top air outlet are communicated with the purification chamber,and a primary filter screen, an activated carbon adsorption screen and a HEPA filter screen are arranged in the purification chamber from the bottom air inlet to the top air outlet. The household airpurification device of the invention can uniformly distribute the air of the air inlet to the primary filter screen by arranging a conical deflector between the bottom air inlet and the primary filterscreen, thereby realizing the overall utilization of the filter screen without dead angles, having good purification effect and avoiding the problem of poor filtration effect caused by only partial utilization of the filter screen. At the same time, a limiting part is arranged in the purification chamber, which is matched with the limiting holes on the primary filter screen, the activated carbonadsorption screen and the HEPA filter screen, and is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a household air cleaning device. Background technique [0002] Air purifiers, also known as "air cleaners", air fresheners, and purifiers, can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution, bacteria , allergens, etc.), products that effectively improve air cleanliness. With the rapid development of the country's economy and the continuous increase of residents' income, the number of units and individuals purchasing various transportation vehicles has increased rapidly, and the environment and climate have changed. The dust and dust weather caused by the increasing number of vehicles in road transportation have brought There are more and more dusts caused by dust and various building constructions. These dusts drift to thousands of households with the flow of air, causing adverse ef...

Problems solved by technology

With the rapid development of the country's economy and the continuous increase of residents' income, the number of units and individuals purchasing various transportation vehicles has increased rapidly, and the environment and climate have changed. The dust and dust weather caused by the increasing number of vehicles in road transportation have brought There are more and more dusts caused by dust and various building constructions. These dusts drift to thousands of households with the flow of air, causing adverse effects and damage to residents' living environment and physical health. Therefore, air purifiers are widely used in ordinary households. However, most of the existing air purifiers have the following problems: the bottom air inlet is too small compared with the filter screen, especially when the air intake speed is fast, the middle part of the filter screen is mainly used for filtering, and the filter The utilization area of ​​the net is too small, and the purification effect is poor
