The patent No. is that 201120579586.3 utility model patent discloses a kind of gas cylinder oxygen protective mask, buckleing (3) by mouth mask body (1), cover band (2), woollen goods forms, the two ends of mouth mask body (1) are connected with cover band (2), woollen goods button (3) is located on cover band (2), it is characterized in that establishing oxygen supplying tube (4) in the lower end, interior two layers of nostril of mouth mask body (1), connect upper apparatus of oxygen supply (5) in the lower end of oxygen supplying tube (4).This gas cylinder oxygen protective mask, has smooth breathing, does not perspire, and moisture proof, avoids pathogenic microorganism to penetrate nasal cavity, the advantage that protective action is good.But, this gas cylinder oxygen protective mask is for hospital, epidemic prevention, dissipation personnel, and be not suitable for common citizen and use in haze environment, especially protective mask is established oxygen supplying tube in the lower end, interior two layers of nostril of mouth mask body, inlet channel and exhaust passage do not separate, the waste gas that user breathes out can mix with clean live gas, causes the gaseous contamination of suction.
[summary of the invention]
The technical problems to be solved in the utility model is to provide the mouth mask that a kind of waste gas that is adapted at using in haze environment, user breathes out can not mix with clean fresh air.
Another technical problem that will solve of the utility model is to provide a kind of respirator of using in haze environment of being adapted at.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of mouth mask, comprise mouth mask body and air supply pipe, the top of mouth mask body comprises air chamber, and the bottom of mouth mask body comprises air leaving cover, between the bottom of air chamber and the top of air leaving cover, has baffle to separate; Described air chamber is inserted in the end of air supply pipe, and the middle part of air chamber rear wall comprises gas outlet.
Above-described mouth mask, air chamber wall is made with comparatively fine and close material, and air leaving cover is made with comparatively sparse material.
Above-described mouth mask, described gas outlet comprises filter cloth.
A kind of respirator, the gas cylinder comprising and air feed mouth mask, described air feed mouth mask is above-mentioned mouth mask, and the air supply pipe of described mouth mask connects gas cylinder, and described gas cylinder is high pressure air bottle.
Above-described respirator, gas cylinder comprises bottle and pressure-reducing valve, and the air inlet of pressure-reducing valve is arranged on the outlet of bottle, and the air supply pipe of mouth mask connects the gas outlet of pressure-reducing valve.
Above-described respirator, comprises the inflator to inflating gas cylinder, and described inflator is multiple-pass gas cylinder.
Above-described respirator, described bottle is carbon fiber bottle.
The inlet channel of mouth mask of the present utility model and exhaust passage isolation, the waste gas that user breathes out can not mix with clean fresh air, and the utilization rate of pure air is high; The respirator of being furnished with this mouth mask is not only adapted at use in haze environment, can also be used for the anaerobic environment of high Mountain area.
