Abstract
The utility model discloses a take respirator of inflatable seal structure, including face guard main part and annular cushion, the sealing that includes of annular cushion includes outer annular seal membrane piece and interior annular seal membrane piece, and the cambered surface cavity of outer annular seal membrane piece and interior annular seal membrane piece is formed the cross section and is the oval -shaped circuit, be provided with annular banded gasbag in the circuit, be provided with the inflation valve on the banded gasbag. The utility model discloses can make better the laminating with the face of outer annular seal membrane piece and interior annular seal membrane piece through inflating to banded gasbag, can carry high leakproofness can, and banded gasbag ability automatically regulated is in the inflation degree at different positions, if in the great place of facial pressurized, its inflation can be less, can be great at its inflation of place that facial pressurized is less to automatically, the physiology shape of facial each unevenness of adaptation guarantees that each one all laminates with sealed with the face is reliable.
Description
Technical field
This utility model relates to a kind of armarium, particularly to a kind of breathing mask.
Background technology
Breathing mask needs to seal laminating with patient facial region in use, to prevent outside air from entering in face shield,
Therefore the sealing of face shield is to weigh the important indicator of its quality.
In prior art, in order to improve sealing and the comfortableness that breathing mask is fitted with face, the most all can
Mask body arranges a flexible cushion, although flexible cushion is set and improves face shield to a certain extent
Sealing, but owing to the face structure of human body is not smooth, cushion is being always with facial contact
Have that some place is fitted preferably, some place is fitted poor, and in order to improve sealing property, generally
The bandage of fixing face shield is required for applying bigger pressure, with ensure cushion each several part all with face good fit,
And bandage applies pressure relatively greatly, the problem that breathing mask wearing comfort reduces can be caused again.
Utility model content
In view of this, the purpose of this utility model is to provide the breathing mask of a kind of band Inflatable sealing structure, to solve
Certainly in prior art, breathing mask and each portion of face can not the technical problems of good contact simultaneously.
The breathing mask of this utility model band Inflatable sealing structure, including mask body, also includes annular soft pad,
Described annular soft pad includes the connecting portion being connected with mask body and the sealing being arranged on connecting portion, institute
State outer ring seal membrane and annular seal membrane, described outer shroud that sealing includes that cross section is arc
The cambered surface cavity composition cross section of shape seal membrane and annular seal membrane is oval circuit, described
Being provided with endless belt-shaped air bag in circuit, described banding air bag is provided with charge valve, described charge valve is stretched
Go out outside sealing.
Further, the bottom of described circuit is provided with the adhesive linkage of bonding banding air bag.
Further, described mask body being provided with annular groove, the connecting portion of described annular soft pad is detachable
Formula is inserted in the annular groove of mask body.
Further, the inwall of described annular groove is provided with the extruding bar of fixing connecting portion.
Further, described mask body is additionally provided with forehead eyelid retractor.
The beneficial effects of the utility model:
The breathing mask of this utility model band Inflatable sealing structure, is provided with banding air bag, face to face in its sealing
After cover is attached in face, by banding airbag aeration, the external annular sealing diaphragm of banding airbag inflation and interior
Annular sealing diaphragm applies pressure, can make outer ring seal membrane and annular seal membrane preferably and face
Portion fits, and can improve the sealing property of sealing；And banding air bag can be automatically adjusted in different parts
Degrees of expansion, such as the place bigger at compression facies, it expands can be less, on the ground that compression facies is less
Its expansion of side can be relatively big, it is thus possible to automatically adapt to facial each portion irregular physiology shape, it is ensured that each portion is equal
Reliably fit with face and seal, owing to banding air bag can improve the sealing in facial each portion, it is thus possible to suitable
When reducing the cinching force fixing breathing mask, improve the comfortableness that face shield is worn.
Accompanying drawing explanation
Fig. 1 is the structural representation of the breathing mask of the present embodiment band Inflatable sealing structure；
Fig. 2 is the main TV structure schematic diagram of annular soft pad；
Fig. 3 is the sectional structure schematic diagram in Fig. 2 along A-A.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As it can be seen, the breathing mask of the present embodiment band Inflatable sealing structure, including mask body 1, also wrap
Including annular soft pad 2, described annular soft pad includes the connecting portion 21 being connected with mask body and is arranged on connection
Sealing 22 in portion, described sealing includes outer ring seal membrane 221 that cross section is arc and interior
Annular sealing diaphragm 222, the cambered surface cavity composition horizontal stroke of described outer ring seal membrane and annular seal membrane
Cross section is oval circuit, is provided with endless belt-shaped air bag 3, described banding air bag sets in described circuit
Being equipped with charge valve 4, described charge valve stretches out outside sealing.
The breathing mask of the present embodiment band Inflatable sealing structure, is provided with banding air bag, works as face shield in its sealing
After being attached in face, by banding airbag aeration, the external annular sealing diaphragm of banding airbag inflation and internal ring
Shape seal membrane applies pressure, can make outer ring seal membrane and annular seal membrane preferably and face
Laminating, can improve the sealing property of sealing；And banding air bag can be automatically adjusted in the swollen of different parts
Swollen degree, such as the place bigger at compression facies, it expands can be less, in the place that compression facies is less
It expands can be relatively big, it is thus possible to automatically adapt to facial each portion irregular physiology shape, it is ensured that each portion
By sealing；And owing to banding air bag can improve the sealing in facial each portion, it is thus possible to suitably reduce fixing
The cinching force of breathing mask, improves the comfortableness that face shield is worn.
As the improvement to the present embodiment, the bottom of described circuit is provided with the adhesive linkage 5 of bonding banding air bag,
Fix banding air bag 5 by adhesive-layer, be avoided that the problem that banding air bag comes off.
As the improvement to the present embodiment, described mask body 1 is provided with annular groove 6, described annular
In the detachable annular groove being inserted into mask body of connecting portion 21 of cushion, the dismounting side of annular soft pad
The most quick.
As the improvement to the present embodiment, the inwall of described annular groove 6 is provided with squeezing of fixing connecting portion
Press strip 7, applies pressure by extruding bar to connecting portion, and that can improve that annular soft pad and mask body assemble can
By property.
As the improvement to the present embodiment, described mask body being additionally provided with forehead eyelid retractor 8, forehead props up
Support device 8 can reduce the mask body pressure to face further, improves wearing comfort.
Finally illustrate, above example only in order to the technical solution of the utility model to be described and unrestricted,
Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, the technical solution of the utility model can be modified or equivalent, without deviating from this reality
