Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, below in conjunction with
The utility model is further detailed by accompanying drawing.
In the present embodiment, the inner side and outer side of mouth mask is on the basis of wearer, and inner side is that mouth mask is when wearing and face
Face laminating and relative side, outside is the side that mouth mask deviates from mutually with face when wearing.
As Figure 1-4, a kind of mouth mask that the utility model embodiment provides, including mask body 1 He
Elastic threads 2, the two ends of mask body 1 connect the two ends of elastic threads 2 respectively, also include strainer valve 3,
Strainer valve 3 is fixed on mouth mask, and strainer valve 3 offers the air admission hole of connected entrance cover body 1 both sides
4, it is provided with filter core 5 in air admission hole 4, the hole wall of air admission hole 4 offers steam vent 6；Also include
The elastic component 7 being connected and covering 8, on elastic component 7, the end away from covering 8 is limited, hides
Shield 8 is slidably connected in air admission hole 4 and is shielded on steam vent 6, and covering 8 is by air inlet
Slip away during the axial breath pressure in hole 4 steam vent 6.
Concrete, according to the difference of profile, mask body 1 is for covering the latter half of human face
(mouth and nose and front jaw), or mask body 1 is only used for covering the nose of face, elastic threads 2 and mouth
Cover body 1 forms loop configuration together, is integrally fastened to the brain of the personnel of wearing.Open on strainer valve 3
It is provided with two gas passages: air admission hole 4 and steam vent 6, steam vent 6 is opened in the hole of air admission hole 4
On wall, i.e. both share one end pipeline, and shared part is the inner side of connector cover body 1, filter
The filter core 5 of valve 3 is positioned in air admission hole 4, and gas enters through air admission hole 4 from the outside of mask body 1
Through filtration core 5 during inner side so that the air of suction is filtered.The present embodiment also has covering 8,
Covering 8 is slidably connected in air admission hole 4, when not by external force, covering 8 block in
On steam vent 6 so that exhaust passage is closed, air inlet is now forced to cannot pass through steam vent
6 and must enter via air admission hole 4；When the personnel of wearing exhale, on the one hand this expiration directly blows to
Air admission hole 4 thus give 8 one axial compressive forces of covering, on the other hand, exhale make inside mouth mask
Air pressure raises, and the pressure differential of mouth mask inner side and outer side also gives covering 8 one axial compressive forces, above-mentioned
The axial compressive force of two aspects all forces covering 8 to recess steam vent 6, so that steam vent 6 energy
Enough exhausts, filter core 5 has a resistance to air-flow, when steam vent 6 is in unimpeded state, exhaust
Hole 6 there is no air resistance and filter core 5 in air admission hole 4 has air resistance, then now gas
Can discharge from steam vent 6, after exhaust terminates, covering 8 is completed to reset, again by elastic component 7
Cover steam vent 6.In the present embodiment, the resistance to sliding of covering 8 should be greater than filter core 5 to air-flow
Pressure and less than above-mentioned two axial compressive force sum, the motion of such covering 8 is the most smooth and easy.
In the present embodiment, the structure of covering 8 needs to meet two conditions, and one is to cover exhaust
Hole 6, two be can the axial stream pressure of air admission hole 4, any knot that disclosure satisfy that the two condition
Structure could act as covering 8.One end of elastic component 7 is limited, and it can be fixed or be connected to mouth mask
On body 1, or fix or be connected on strainer valve 3.
The mouth mask that the present embodiment provides, during air-breathing, air must be by filter core 5 inlet port of air admission hole 4
In cover, and when exhaling, covering 8 is pushed away steam vent 6 by the air pressure of expiration so that the gas of exhalation
Body breathes out through steam vent 6.So, the expiration of wearer and air inlet, via different passages, reduce
The filtration burden of filter core 5.
In the present embodiment, it is preferred that strainer valve 3 is fixed on the center of mask body 1, center
Position faces the position that nose is exhaled, and the stream pressure of reception is bigger so that the operation of covering 8
The most smooth and easy.
In the present embodiment, it is preferred that steam vent 6 has multiple, multiple steam vents 6 be uniformly opened in into
On the hole wall of pore 4, uniform steam vent 6 makes to give vent to anger the most uniform.
In the present embodiment, further, elastic component 7 is flexible mask, and flexible mask is covered on mouth mask
On body 1, one end of covering 8 is connected on flexible mask, and such mouth mask is double-decker, makes
Strainer valve 3 is whole is between flexible mask and mask body 1, mouth mask outer surface is the most smooth.
In the present embodiment, further, covering 8 is tubular elements, and the end of tubular elements is provided with close
Packing 10, tubular elements is connected on hole wall by sealing gasket 10, and being slidably connected of tubular elements is the most suitable
Freely, sealing gasket 10 makes covering 8 the most thorough to covering of steam vent 6.
In the present embodiment, further, tubular elements having receiving space, filter core 5 is limited in appearance
Receive in space, i.e. filter core 5 is fixed in covering 8, so filter core 5 is converted the pressure of gas
For the gas pressure to covering 8 so that the operation of covering 8 is more smoothly.
In the present embodiment, further, there is block 9, block 9 and flexible mask in tubular elements
Between space for accommodate space, be so easy to the installation and removal of filter core 5.
Only by the way of explanation, describe some one exemplary embodiment of the present utility model above, need not put
Doubt, for those of ordinary skill in the art, in the case of without departing from spirit and scope of the present utility model,
By various different modes, described embodiment can be modified.Therefore, above-mentioned accompanying drawing and being described in
It is substantially illustrative, should not be construed as the restriction to the utility model claims.
