Low-noise air purifier capable of efficiently reducing noise

Abstract

The invention discloses a low-noise air purifier capable of efficiently reducing noise. The air purifier comprises a machine box outer shell, a filter purifying mechanism installed at the inner frontend of the machine box outer shell, a fan driving mechanism installed at the rear of the filter purifying mechanism and an air outlet turbulence mechanism installed at the inner rear end of the machine box outer shell; two ends of the machine box outer shell are separately provided with an air inlet and an air outlet, and the interior of the part, close to the air inlet, of the machine box outer shell is provided with flag wind-blocking belts; the air outlet turbulence mechanism includes flow guide plates and an air diffusion plate, and the flow guide plates are installed on two sides of the machine box outer shell perpendicular to a wind direction; the filter purifying mechanism has a drawer type connection mode, the filter purifying mechanism is connected with a drawer plate, and the filter purifying mechanism is fixedly connected with the drawer plate through an installation hole; and the exterior of the fan driving mechanism is provided with a sound-reducing outer cover, and sound-insulation plates are arranged between the sound-reducing outer cover and the machine box outer shell. The air purifier provided by the invention has a simple and compact structure, and adopts a combination of air guiding, sound insulation and air stabilizing to realize high-efficiency noise reduction treatment of the air purifier during use, thereby improving usage experience of users.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to a low-noise air purifier with high efficiency and noise reduction. Background technique [0002] Air purifiers are also known as products that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve air cleanliness . [0003] The WHO research report shows that among the 4.3 million deaths caused by kitchen air pollution in the world in 2012, stroke accounted for 34%, chronic obstructive pulmonary disease and ischemic heart disease accounted for 22% and 26% respectively. Accounted for about 6% of lung cancer. [0004] In a research project on disease risk assessment in the famous British medical journal "The Lancet", kitchen air pollution (smoke) has been listed as the biggest health hazard after high blood pressure, smoking and a...

Problems solved by technology

[0006] However, the current air purifiers produce noise in the air duct of the air purifier, and the wind speed is strong, resulting in rapid air circulation and poor user experience. The main reasons are as follows:

[0007] (1) Mainly because of the dense filter screen in the filter section, in order to improve the purification effect of the air purifier, the filter screen is usually encrypted, so that when the flowing air flows into the filter screen, due to the large resistance, wind noise is generated, and it is also Greatly affected the service life of the filter;

[0008] (2) In addition, due to the use of motors and fans, noise will also be generated;

[0009] (3) There is no air guide mechanism at the air outlet, resulting in a fast air flow rate, causing the indoor air to easily generate air swirl, and poor user experience
