In order to create a comfortable and quiet indoor environment, it is important to effectively remove noise generated from the air purifier.
In the prior art, noise is isolated by arranging a sound isolation structure with a single structure, and the effect is poor, so the utility model aims to provide a sound isolation and noise reduction structure with multiple sound isolation and noise reduction effects, and the sound isolation effect is better.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provides a sound insulation and noise reduction structure for an air purifier.
The aim of the utility model is achieved by the following technical scheme: a sound insulation and noise reduction structure for air purifier, including be cavity cube form's shell, set up in fan and the amortization subassembly in the shell, the amortization subassembly can be separated the inner chamber of shell into first cavity and be located the second cavity of first cavity top, the fan set up in the first cavity, all be provided with a plurality of inlet port on the left and right side face of shell in order to constitute the air inlet region, wherein, the area of air inlet region can be greater than the cross sectional area of the air inlet channel of fan.
Preferably, the area of the cross section of the second cavity can be gradually increased in a direction along the bottom surface of the housing toward the top surface of the housing.
Preferably, the muffler assembly includes a housing having both ends opened to define a muffler chamber, and the cross-sectional shape of the housing can be defined by a trapezoid.
Preferably, a sound absorbing material layer is attached to the inner wall of the sound deadening chamber.
Preferably, the muffler assembly further includes a first baffle and a second baffle disposed opposite each other at the top of the housing.
Preferably, the top of the shell is provided with a plurality of air outlet holes.
Preferably, filter cotton is arranged on the left side surface and the right side surface of the shell.
The utility model has the following advantages:
(1) The area of the air inlet area is large, so that the air flow can be prevented from entering from the air inlet area at too high flow speed, wind noise is generated, and the purpose of reducing the noise is achieved.
(2) Through setting up amortization chamber and sound absorbing material layer, can produce the noise to the fan and carry out further reduction.
(3) The left and right sides of the shell are provided with filter cotton. The air filtering device has the advantages that the air filtering device can filter air through the filtering cotton, and the air filtering device can play a role in sound insulation.
Drawings
FIG. 1 is a schematic view of a sound-deadening structure of the present utility model;
fig. 2 is a schematic structural view of the muffler assembly.
In the figure, a 1-shell, a 2-fan, a 3-silencing component, a 1 a-first cavity, a 1 b-second cavity, a 5-air inlet area, a 6-shell, a 7-silencing cavity, an 8-sound absorbing material layer, a 9-first baffle, a 10-second baffle, 11-air outlet holes and 12-filter cotton.
Detailed Description
The utility model is further described below with reference to the accompanying drawings, the scope of the utility model not being limited to the following:
as shown in fig. 1 and 2, the present utility model provides a sound insulation and noise reduction structure for an air purifier, which comprises a casing 1 having a hollow cube shape, a fan 2 and a noise reduction assembly 3 disposed in the casing 1, wherein the noise reduction assembly 3 can divide an inner cavity of the casing 1 into a first cavity 1a and a second cavity 1b located above the first cavity 1a, the fan 2 is disposed in the first cavity 1a, and a plurality of air inlet holes are disposed on left and right sides of the casing 1 to form an air inlet region 5, wherein an area of the air inlet region 5 can be larger than a cross-sectional area of an air inlet channel of the fan 2.
