Problems solved by technology

At present, air purifiers mainly use centrifugal fans or axial fans to supply air in one direction, resulting in high air supply noise. Under the limitation of performance indicators, the noise value is close to the limit
At the same time, the existing air purifiers generally only process indoor air, without the function of supplementing fresh air
In addition, most users think that the clean air generated by existing air purifiers cannot be evenly distributed in a room or a closed space, which has a certain distribution limitation

Embodiment Construction

[0068] figure 1 is a schematic perspective view of an air cleaner 100 according to an embodiment of the present invention. figure 2 yes figure 1 A schematic exploded view of the air cleaner 100 is shown. image 3 yes figure 1 A schematic cross-sectional view of the air cleaner 100 is shown. The air purifier 100 of the embodiment of the present invention may generally include a housing 200 , a filter element 120 , a fresh air system 900 , and a laminar flow fan 110 . The housing 200 is provided with an indoor air inlet 201 and an air outlet 202 . The filter element 120 is disposed in the housing 200 , and indoor air enters the housing 200 from the indoor air inlet 201 and reaches the filter element 120 for filtering. The fresh air system 900 is connected to the housing 200 and has an outdoor air inlet 203 through which outdoor air enters the housing 200 . The laminar flow fan 110 is arranged in the casing 200, and an air inlet passage 302 is formed at the center thereof,...

Abstract

The invention provides an air purifier, which comprises a shell, a filter element, a fresh air system and a laminar flow fan. The shell is provided with an indoor air inlet and an air outlet. The filter element is arranged in the shell, and indoor air enters the shell from the indoor air inlet and then reaches the filter element to be filtered. The fresh air system is connected with the shell andprovided with an outdoor air inlet, and outdoor air enters the shell through the outdoor air inlet. The laminar flow fan is arranged in the shell, the laminar flow fan is provided with an air inlet channel, the indoor air filtered by the filter element and / or the outdoor air entering the shell reach / reaches the air inlet channel, the laminar flow fan disturbs the air reaching the air inlet channelthrough the fluid viscosity effect to form laminar flow air, and the laminar flow air is exhausted out of the shell from the air outlet. According to the air purifier, the laminar flow fan is arranged in the shell, and meanwhile, the fresh air system is arranged, so that the use experience of a user is effectively improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air purifier. Background technique [0002] With the rapid development of the economy, the massive consumption of energy produces a large amount of harmful substances. The earth where people live is full of particulate matter, sulfur oxides, nitrogen oxides and hydrocarbons, which seriously threaten people's health. In order to make the air fresh, an air purifier is needed to purify the air. At present, air purifiers mainly use centrifugal fans or axial fans to supply air in one direction, resulting in high air supply noise. Under the limitation of performance indicators, the noise value is close to the limit. At the same time, the existing air purifiers generally only process indoor air, without the function of supplementing fresh air. In addition, most users think that the clean air generated by existing air purifiers cannot be evenly distributed in a room or a cl...
