Abstract
The utility model discloses a kind of noise elimination mouth mask, including enclosure portion, sound absorption cotton is provided with the enclosure portion, the sound absorption cotton, which is interlocked, to be filled in enclosure portion, is pressed close on the enclosure portion on mouth side and is provided with noise reduction layer.Compared with prior art, a kind of noise elimination mouth mask of the present utility model, can effectively weaken wearer's sound, prevent in his incoming human ear of sound.Such as in life, noise elimination mouth mask can effectively solve the problem that influence and interference problem of the cough etc. in public to other people, while individual privacy can also be protected, reduce information leakage when making a phone call；Medical aspect, doctor can avoid sound interference in operation mutually by wearing noise elimination mouth mask；On Military application, the use of noise elimination mouth mask can effectively reduce soldier by the possibility of enemy army's detected sound wave, strengthen itself disguised.
Description
Technical field
The utility model is related to a kind of mouth mask, particularly a kind of noise elimination mouth mask, belongs to daily product technical field.
Background technology
More attention with the public to air pollution problems inherent, mouth mask has become current trip necessary article.In mouth mask
In Historic Evolution, although its outward appearance and design structure are updated, but its function be limited in dust pollution every
From effect.At present, mouth mask is used and popularized and reached new upsurge, and people it is also proposed to the function and practicality of mouth mask
Higher requirement.And the invention of muffling mask also add the blocking effect to noise, improve except energy air-isolation pollution
The performance of mouth mask.
Utility model content
The utility model technical issues that need to address are to be directed to above-mentioned the deficiencies in the prior art, and providing one kind can disappear
Weak wearer's sound, blocking sound transmission and the noise elimination mouth mask for weakening transmission acoustic energy.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
Sound absorption cotton is provided with a kind of noise elimination mouth mask, including enclosure portion, the enclosure portion, the sound absorption cotton, which is interlocked, fills out
Fill in enclosure portion, press close on the enclosure portion on mouth side and be provided with noise reduction layer.
As further preferred scheme, the noise reduction layer is the bulge-structure being distributed on noise elimination mouth mask surface.
As further preferred scheme, at least one layer of off beat layer, institute are provided with the institute enclosure portion outer surface
It is that sound mouthful is disturbed in distribution on single-layer nonwoven, the non-woven fabrics to state off beat layer.
As further preferred scheme, the edge for disturbing sound mouthful be jagged edge structure.
Beneficial effect：
Compared with prior art, a kind of noise elimination mouth mask of the present utility model, can effectively weaken wearer's sound, prevent
In his incoming human ear of sound.Such as in life, noise elimination mouth mask can effectively solve the problem that the influence to other people such as cough in public
And interference problem, while individual privacy can also be protected, reduce information leakage when making a phone call；Medical aspect, doctor can lead to
Cross wear noise elimination mouth mask avoid mutually operation in sound interference；On Military application, the use of noise elimination mouth mask can effectively drop
Low soldier strengthens itself disguised by the possibility of enemy army's detected sound wave.
Brief description of the drawings
Fig. 1 is the sectional view of enclosure portion；
Fig. 2 is the structural representation of off beat layer；
Wherein, 1- enclosure portions,
2- sound absorption cottons,
3- noise reduction layers,
4- off beats layer,
5- disturbs sound mouthful.
Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of noise elimination mouth mask of the present utility model, including enclosure portion 1, the enclosure portion 1 is interior to be set
There is sound absorption cotton 2, the sound absorption cotton 2 is staggeredly filled in enclosure portion 1, presses close on the enclosure portion 1 and be provided with mouth side
Noise reduction layer 3.
The noise reduction layer 3 is the bulge-structure being distributed on noise elimination mouth mask surface.
At least one layer of off beat layer 4 is provided with the outer surface of enclosure portion 1, the off beat layer 4 is single-layer nonwoven, institute
State distribution on non-woven fabrics and disturb sound mouthful 5, the off beat layer 4 of multilayer can successively decay the sound sent out.
The edge for disturbing sound mouthful is jagged edge structure, and jagged edge structure can carry out sound to the sound sent
Change on color, interference sends the stability of sound transmission.
The noise elimination mouth mask improves original mask material, and sound absorption cotton 2 is lightweight, porous, loose and ventilative to incidence
Sound has the material of absorption.Material internal has the hole of a large amount of small connections, and sound wave gos deep into material along these holes
Can be by the reflection of countless fibers, superposition, collision after internal.Such as Fig. 2 technical principle：Acoustic energy E, sound are generated after human body sounding
Ripple enters left and right collision behind inside and acoustic energy is converted into heat energy Q with material generation rubbing action.At the same time, partial sound is inhaled
Sound cotton reflects.In this process, the conservation of energy understands that E=Q+E1+E ', energy is gradually consumed, sound
E ' can be reduced to from E, so as to effectively play deadening.
The sound absorption cotton 2 that noise elimination mouth mask is used will not only meet lightweight, porous, loose and ventilative physical structural characteristic, together
When for good mouth mask filtrate, also require that its respiratory resistance is small and user's comfortable wearing, sound absorption cotton 2 specification is a diameter of 1-
The material of 4 microns of superfine fibre and a diameter of 20-30 microns chopped fiber composition, is realized by the processing method blowed and fused
The soft sound-absorbing material of more light weight is made of trickleer fiber.This means acoustic energy is easily accessible this material and friction dynamics
It is bigger.
When sound wave incident is to porous material surface, cause the air vibration in micropore, due to frictional resistance and air
Viscous resistance and conduction of heat, heat energy is converted into by quite a few acoustic energy, so as to play sound absorption, effectively blocks sound
Propagate and weaken transmission acoustic energy, reach good soundproof effect.
It is described above, only the application preferably embodiment, but the protection domain of the application is not limited thereto,
Any one skilled in the art is in the technical scope that the application is disclosed, the change or replacement that can be readily occurred in,
It should all cover within the protection domain of the application.Therefore, the protection domain of the application should be with scope of the claims
It is defined.
