Abstract

The utility model discloses a gasbag mask, which consists of a gasbag and an outer cover (2), and is characterized in that the outer cover (2) is formed by overlapping a plurality of layers of gauze; the edge of the outer cover is provided with four soft ropes (6); the center of the outer cover is provided with a snap button (5); the inside of the gasbag is in a hollow structure, and the shape thereof is a hemispherical shape; a gas-guide tube (3) is inserted into the cavity of the gasbag by a connector (7) on the gasbag; an one-way gas outlet valve (4) is positioned on the side of the gasbag; the soft ropes (6) are fixed on the two sides of the edge of the gasbag; and the snap button (5) on the gasbag is arranged to be corresponding to the snap button (5) on the outer cover (2). Since the gasbag is arranged, the utility model has the advantages of good purification effect, no exhalation resistance and no air leakage.

Description

The air bag mouth mask

Technical field:

The utility model relates to a kind of mouth mask that is used for daily life.

Background technology:

Modern workman is used for the dustproof mouth mask two types, and a kind of is the cotton yarn mouth mask, with the dust in the multilayer cotton gauze filtered air; Another kind is the anti-dust respirator that has the activated carbon filtration mouth, all there is following common deficiency in these two kinds of anti-dust respirators: have the interface slit between mouth mask and the workman's face, owing to there is expiratory resistance, when workman's incoming call air, material in the filter course blocks flowing of air, filter course can't block dust, and air can not get effective purification, and the gas leak phenomenon of generation also makes airborne dust be easy to directly enter in the nostril through the interface slit.

Summary of the invention:

The utility model purpose provides the air bag mouth mask of a kind of good purification, no expiratory resistance, no gas leak phenomenon.

The technical scheme that the utility model adopted is: a kind of air bag mouth mask, by air bag, outer cover is formed, it is characterized in that: described outer cover is made up of the stack of multilayer gauze, outer shroud rim has four tightropes, the outer cover center is provided with double buckle, described air bag is by pneumatophore, wireway, unidirectional air outlet valve, double buckle, tightrope is formed, air bag inside is hollow-core construction, the outer hemispherical that forms, wireway stretches into the air bag cavity by the interface on the air bag, unidirectional air outlet valve is positioned at the air bag side, and tightrope is fixed on the cell edges both sides, double buckle on the air bag and the corresponding setting of double buckle on the outer cover.

The utility model has the advantage of good purification, no expiratory resistance, no gas leak phenomenon because air bag is arranged.

Description of drawings:

Fig. 1 is a structure chart of the present utility model;

Fig. 2 is the structure chart of the utility model air bag;

Among the figure, the 1st, air bag, the 2nd, outer cover, the 3rd, wireway, the 4th, unidirectional air outlet valve, the 5th, double buckle, the 6th, tightrope, the 7th, interface.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments the utility model is further specified:

From Fig. 1, Fig. 2 as can be known, the utility model air bag mouth mask is made up of air bag, outer cover 2 two major parts, and outer cover 2 is made up of the stack of multilayer gauze, is cuboid, and outer shroud rim Corner Strapped has four tightropes 6, and the outer cover center is provided with double buckle 5; Air bag is made up of pneumatophore 1, wireway 3, unidirectional air outlet valve 4, double buckle 5, tightrope 6, air bag inside is hollow-core construction, the outer hemispherical that forms, wireway 3 is elongated flexible pipes, wireway 3 stretches into the air bag cavity by the interface on the air bag 7, and unidirectional air outlet valve 4 is positioned at the air bag side, and tightrope 6 is fixed on the cell edges both sides, double buckle 5 corresponding settings on double buckle 5 on the air bag and the outer cover 2 are connected as a single entity air bag, outer cover 2 by double buckle 5.

Using method: first inlet with wireway 3 is connected on the micro air pump or is placed on the place of clean air air, just air bag, outer cover 2 are connected as a single entity by double buckle 5 then, be fixed on workman's face with the tightrope 6 on air bag, the outer cover 2 respectively again, air bag covers workman's nostril and mouth like this, itself and outside are separated, clean air is in wireway enters air bag, and the workman carries out the gas exchange in air bag, and unnecessary gas is discharged outside the air bag by unidirectional air outlet valve.
