Degree.No more than 40 degree, conducting element can preferably play acceleration wind for first windward side and the second windward side and wind direction angulation
The effect of stream, if angulation is greater than 40 degree, distinguished and admirable acceleration effect when flowing through conducting element can be deteriorated, when angulation becomes larger
When close to 90 degree, conducting element can play the effect for hindering distinguished and admirable flowing instead.
Further, the gradient of first windward side is greater than or equal to the gradient of second windward side.Using first
The gradient of windward side be more than or equal to the second windward side the gradient structure, since air outlet becomes larger, it is distinguished and admirable
When flowing through the first surface of conducting element, wind pressure is that gradually gradient reduces, and improves the circulation efficiency of air, reaches energy conservation
The effect of noise reduction.
Further, the conducting element further includes second surface, and the first surface and second surface seal closure is formed
Filled cavity, first surface and second surface junction rounding off.First surface and second surface junction rounding off,
Windage is reduced, it is whole streamlined, reduce the source of noise generation.
Further, the conducting element is set on the left of the air duct outlet air end in half region.The installation of conducting element
Position also will affect distinguished and admirable shunting effect, is the region that wind flow is concentrated in the half region of air duct outlet air end left side, leads
It flows part installation in this area, could preferably play the effect of noise reduction shunting.
Further, acoustic damping materials are filled in the filled cavity, the inner wall in the air duct is covered with acoustic damping materials, described
Acoustic damping materials are polyurethane foam sound-absorbing material.
Compared with prior art, the utility model has the beneficial effects that:
The air duct noise-reducing structure of a kind of air purifier provided by the utility model, for the spy of centrifugal blower air-out passage
Different structure optimizes the flowing of air duct interior air-flow, reduces flow resistance, while benefit by the way that conducting element is arranged at duct outlet
Acoustic damping materials are filled in conducting element, are further reduced the noise of air purifier generation；Effective solution centrifugal blower
Air outlet one side air output is big, and air output small problem in one side keeps the outlet air at outlet air end more uniform, increases outlet port
Air output in place's unit time unit area reduces making an uproar for blower to reduce the workload of centrifugal blower indirectly
Sound, and the air agitation generated at air outlet is also reduced, on the other hand also reduce the point for generating noise.
Invention is further described in detail with reference to the accompanying drawings and detailed description.

Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
As shown in Figure 1 and Figure 2, the air duct noise-reducing structure of a kind of air purifier, including be fixedly connected sequentially support plate 1,
Air inlet 8, support plate 1,2 and of spiral case cover are offered on spiral case cover 2 and motor fixing plate 3, support plate 1 or/and motor fixing plate 3
3 three of motor fixing plate seals to form air duct 4, and air duct noise-reducing structure further includes conducting element 5, and conducting element 5 is set to air duct outlet air end
6, conducting element 5 includes first surface 51, and first surface 51 includes the first windward side 511 and second set gradually by air-out direction
Windward side 512, the first windward side 511 and the second windward side 512 and wind direction institute are at an acute angle no more than 40 degree.
The gradient of first windward side 511 is not less than the gradient of the second windward side 512.Using the gradient of the first windward side 511
It is distinguished and admirable to flow through conducting element since air outlet becomes larger more than or equal to the structure of the gradient of the second windward side 512
When 5 first surface 51, wind pressure is that gradually gradient reduces, and improves the circulation efficiency of air, reaches energy-saving and noise-reducing
Effect.
Conducting element 5 further includes second surface 52, and first surface 51 and 52 seal closure of second surface form filled cavity 7, the
52 junction rounding off of one surface 51 and second surface.52 junction rounding off of first surface 51 and second surface reduces
Windage, it is whole streamlined, reduce the source of noise generation.
Conducting element 5 is set in 6 left side half region of air duct outlet air end.The installation site of conducting element 5 also will affect wind
The shunting effect of stream, is the region that wind flow is concentrated in 6 left side half region of air duct outlet air end, and conducting element 5 is installed herein
In region, the effect of noise reduction shunting could be preferably played.
Acoustic damping materials are filled in filled cavity 7, the inner wall in air duct 4 is covered with acoustic damping materials, and acoustic damping materials are polyurethane foam
Foam sound-absorbing material.
When centrifugal blower sucks air from air inlet 8, into air duct 4, air duct outlet air end 6 is then arrived at, due to air duct 4
Special shape, cause the distinguished and admirable left side for being largely focused on air duct outlet air end 6, thus centrifugal fan air outlet caused to go out on one side
Air quantity is big, and one side air output is small, thus the non-uniform problem of the outlet air at outlet air end, therefore be arranged at air duct outlet air end 6 and lead
Flow part 5, the two sides of conducting element 5 respectively with 3 sealing welding of support plate 1 and motor fixing plate, and first surface 51 and second
52 seal closure of surface, so that support plate 1, motor fixing plate 3, first surface 51 and second surface 52 4 are closed to form filling
Chamber 7, filled cavity 7 is interior to insert acoustic damping materials polyurethane foam, reduces the additional noise of the intervention bring of conducting element 5；Conducting element 5
Installation site be to be located in the half region in the left side of air duct outlet air end 6, this region is the distinguished and admirable region for concentrating discharge, is led
Stream part 5 is located at this region can play the effect of shunting well, increase air output, and then can also reduce the negative of centrifugal blower
Lotus；First surface 51 and second surface 52 on conducting element 5 cooperate it is streamlined, make wind speed by air duct outlet air end 6 when
Time becomes larger.
The above embodiment is only the preferred embodiment of the present invention, and the model of the utility model protection cannot be limited with this
It encloses, the variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the utility model belong to this
Utility model range claimed.
