Abstract
The utility model provides an air cleaner duct attenuation structure, including wind channel, liner, the inboard in wind channel be provided with the liner. Air cleaner duct attenuation structure be provided with the liner in the wind channel inboard, the shared space of liner is less, can not cause the increase of air cleaner volume, cause the hindrance also can not for inside other structures of organism, the liner has absorption to sound, and self is the elasticity material, and sound, noise reduction, shock attenuation, the noise proof effect of inhaling is played in reducible vibrations, the liner has covered the back -off isotructure simultaneously, reduces the windage in the wind channel, and it increases CADR value ( clean air volume) to reach, and the noise reduction plays the effect that beautifies the wind channel inner wall simultaneously again.
Description
Technical field
The utility model belongs to air cleaner field, especially relates to a kind of air cleaner duct attenuation structure.
Background technology
Along with the raising of people's living standard, add that present atmosphere pollution is more serious, people more and more thirst for breathing clean air, in modern metropolitan cities, people are more and more unwilling to go out, prefer to treat in own home and friend, household is amusement together, life, particularly people such as to play card at home etc. recreation time, just need to treat for a long time indoor, be trapped among the surrounding of desk, but for a long time in indoor activity, room air is easily caused such as to be breathed, the pollution that smoking etc. causes, and most people is all selected at indoor location ventilation fan at present, the air of indoor is extracted out outdoor, again the air of outdoor is put into indoor, this mode upgrades room air, but run into haze weather, time outdoor air quality is also poor, the mode of this ventilation, effectively can not keep indoor air clean, occur that some are specifically designed to indoor, are fixed in indoor ceiling in the market, and faced the air purifier of below desk.But, due to pure air directly from the air outlet of air cleaner out, therefore, the noise of air draft, vibrations, and how to reduce windage be a technical difficult problem.
Summary of the invention
In view of this, the utility model is intended to propose a kind of air cleaner duct attenuation structure, can play the effect of sound-absorbing, noise abatement, damping, sound insulation.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of air cleaner duct attenuation structure, comprise air channel, liner, the inner side in described air channel is provided with liner.
Further, described liner is provided with some through holes, the diameter of through hole is identical with the diameter of the screw column of air duct surfaces, and the quantity of through hole is identical with the quantity of screw column.
Further, described liner is provided with uniformly some hemispheric sound-absorbing balls.
Further, the radius of described sound-absorbing ball is 1mm-1.5mm.
Further, the bottom inside described air channel and top are provided with button pin, and liner is fixed on inside air channel by buckleing pin.
Further, the material of described liner selects silencing cotton.
Further, the thickness of described liner is 1mm-3mm.
Further, the thickness of described liner is 2mm.
Relative to prior art, air cleaner duct attenuation structure described in the utility model has following advantage:
(1) air cleaner duct attenuation structure described in the utility model is provided with liner inside air channel, and liner takes up space less, can not cause the increase of air cleaner volume, causes obstruction also can not to other structures of internal body; Liner has absorption to sound, and self is elastic material, can reduce vibrations, play the effect of sound-absorbing, noise abatement, damping, sound insulation; Liner covers the structures such as the back-off inside air channel simultaneously, reduces the windage in air channel, reaches and increases CADR value (Clean air delivery rate), reduces noise, plays again the effect beautifying air channel inwall simultaneously.
(2) pad surfaces described in the utility model is provided with some sound-absorbing balls, and sound-absorbing ball increases the surface area of liner, greatly improves the function of its sound-absorbing, noise abatement.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the sectional view of the air cleaner duct attenuation structure described in the utility model embodiment.
Description of reference numerals:
1-air channel, 2-liner, 3-screw column, 4-sound-absorbing ball, 5-detains pin.
Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of air cleaner duct attenuation structure, comprises air channel 1, liner 2, and the inner side in described air channel 1 is provided with liner 2.
Described liner 2 is provided with some through holes, and the diameter of through hole is identical with the diameter of the screw column 3 of air duct surfaces, and the quantity of through hole 2 is identical with the quantity of screw column 3.
Described liner 2 is provided with uniformly some hemispheric sound-absorbing balls 4, sound-absorbing ball 5 increases the surface area of liner 2, greatly improves the function of its sound-absorbing, noise abatement.
The radius of described sound-absorbing ball 4 is 1mm-1.5mm.
Bottom inside described air channel 1 and top are provided with detains pin 5, and liner 2 is fixed on inside air channel 1 by buckleing pin 5, and fixation, installs simple and convenient.
The material of described liner 2 selects silencing cotton, and silencing cotton is environment-friendly materials, smooth surface, can play the effect reducing windage.
The thickness of described liner 2 is 1mm-3mm.
The thickness of described liner 2 is 2mm.
Air cleaner duct attenuation structure is provided with liner 2 inside air channel 1, liner 2 take up space less, the increase of air cleaner volume can not be caused, cause obstruction also can not to other structures of internal body; Liner 2 pairs of sound have absorption, and self are elastic materials, can reduce vibrations, play the effect of sound-absorbing, noise abatement, damping, sound insulation; Liner 2 covers the structures such as the back-off inside air channel 1 simultaneously, reduces the windage in air channel 1, reaches and increases CADR value (Clean air delivery rate), reduces noise, plays again the effect beautifying air channel 1 inwall simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
