SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model aims to provide a breathing protection device, the face of which can be convenient for ventilate, and the wearing comfort level is improved.
The purpose of the utility model is realized by adopting the following technical scheme:
a breathing protection device comprises an outer cover, an inner cover and a suction one-way valve, wherein the suction one-way valve is arranged in the middle of the inner cover; a plurality of elastic connecting rods are arranged on the outer periphery of the air suction one-way valve and circumferentially arrayed around the central axis of the air suction one-way valve; one end of the elastic connecting rod is connected with the air suction one-way valve, and the other end of the elastic connecting rod is fixedly connected to the inner cover; a plurality of air guide channels are arranged on the inner side of the inner cover and are circumferentially arrayed around the central axis of the inner cover; one end of the air guide channel extends to the middle part of the inner cover, and the other end of the air guide channel extends to the outer edge of the inner cover.
Preferably, the elastic connecting rod is connected with the air suction one-way valve in a clamping manner.
Preferably, a plurality of sweat-absorbent pads are provided on the inner side of the inner cover in a circumferential array around the central axis of the inner cover.
Preferably, the top end of the outer cover is provided with a nose support which is used for being attached to the bridge of the nose of a human body.
Preferably, the two sides of the outer cover are both provided with elastic annular bands, and each elastic annular band is provided with a line body.
Compared with the prior art, the beneficial effects of the utility model reside in that: its check valve of breathing in is connected with the inner cover through the elastic connecting rod, and when exhaling, certain stretching can be done to the elastic connecting rod, makes the person of wearing can have enough space, and it is smooth and easy to exhale, can effectively reduce the person of wearing face and the laminating time of inner cover, reduces the possibility of perspiring or face reddening.
In addition, a plurality of air guide channels are arranged on the inner side of the inner cover, exhaled air can be guided out through the air guide channels, the situation that the exhaled air is condensed on the inner cover and the inner cover is wet is avoided, sweating can be reduced, and the wearing is comfortable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 10. a housing; 11. a nose pad; 12. loosening and tightening a ring belt; 13. a wire body; 20. an inner cover; 21. a sweat-absorbent pad; 22. an air guide channel; 30. an air suction check valve; 31. an elastic connecting rod.
Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
as shown in fig. 1, the respiratory protection device comprises an outer cover 10, an inner cover 20 and an inspiration one-way valve 30, wherein the inspiration one-way valve 30 is arranged in the middle of the inner cover 20, specifically, a plurality of elastic connecting rods 31 are arranged on the outer periphery of the inspiration one-way valve 30, and the elastic connecting rods 31 are circumferentially arrayed around the central axis of the inspiration one-way valve 30. One end of the elastic connecting rod 31 is connected to the air suction check valve 30, and the other end of the elastic connecting rod 31 is fixedly connected to the inner cover 20.
On the basis of the structure, when the breathing protection device is used, the inner cover 20 can be worn on the face of a human body, the human body can inhale through the inhaling one-way valve 30, the inhaling one-way valve 30 is connected with the inner cover 20 through the elastic connecting rod 31, and when exhaling, the elastic connecting rod 31 can be stretched to a certain extent, so that a wearer can have enough space and exhale smoothly. It should be noted that the elastic connecting rod 31 may be made of rubber or silica gel, which has elastic recovery capability.
In addition, since the inner shroud 20 is provided inside with the plurality of air guide passages 22, the plurality of air guide passages 22 are circumferentially arrayed around the central axis of the inner shroud 20. One end of the air guide passage 22 extends to the middle of the inner cover 20, and the other end of the air guide passage 22 extends to the outer edge of the inner cover 20, so that the exhaled air can be guided out through the air guide passage 22, and the exhaled air is prevented from being condensed on the inner cover 20.
It should be noted that, in the actual manufacturing process, the inner cover can be made of non-woven fabric, when in production, the non-woven fabric used as the inner cover is cut with openings at intervals to form the air guide channel, and when in wearing, the cut openings can be pulled open to realize air guide.
Preferably, the elastic connecting rod 31 may be connected to the air suction check valve 30 in a snap-fit manner, so as to facilitate the detachment of the air suction check valve 30 from the inner cover 20, so that the air suction check valve 30 can be replaced, thereby facilitating frequent use.
Preferably, a plurality of sweat-absorbent pads 21 are also provided, particularly on the inner side of the inner cover 20, the plurality of sweat-absorbent pads 21 being circumferentially arrayed about the central axis of the inner cover 20. So, the soft sweat-absorbing gasket 21 that has the function of absorbing water can absorb the sweat that the person of wearing produced when the higher environment of temperature is used, or the moisture that condenses on inner cover 20 of exhaling, improves the person of wearing's comfort level greatly.
Preferably, the top end of the outer cover 10 is provided with a nose pad 11, and when the nose pad 11 is worn, the nose pad can be attached to the bridge of the nose of a human body, so that the wearing stability is better.
Preferably, the two sides of the outer cover 10 are provided with elastic girdle bands 12, and each elastic girdle band 12 is provided with a wire 13, so that the wearing structure can be stably worn by wearing the two elastic girdle bands 12 on two ears of a human body and tying the wire 13 of the two elastic girdle bands 12.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
