Gas mask for using in escaping from fire}

The present invention relates to a gas mask for evacuation of fire, and more particularly, a primary breathing means for breathing the purified air through the air purifying filter, and the oxygen supplied to the mask to allow rebreathing. It is related with a gas mask which is provided with each of the second breathing means to effectively evacuate the fire by selectively using the 1st and 2nd breathing means according to the on-site environment where the fire occurred.

In general, when a fire occurs in a building or a facility, a large amount of toxic gas harmful to the human body is generated in the indoor air, and a large amount of smoke is generated, which makes it difficult to secure the view of the refugee.

In order to minimize human accidents in such a fire, people exposed to lack of oxygen due to disaster or toxic gas can breathe sufficiently during the time to escape from this dangerous situation, and evacuees are delayed in finding escape passages or emergency exits even in heavy smoke. This should be secured without vision.

In view of this, a gas mask or oxygen generating mask is used as a means to remove the danger from the toxic gas. However, in the case of the gas mask, the toxic substance is effectively protected, but a high concentration of organic compound gas, etc., is delayed in time. The filter was rapidly contaminated and lost its function, resulting in an oxygen-deprived emergency, resulting in difficulty in breathing.

Therefore, even though harmful air is harmful, it is useful for oxygen generating masks that use compressed oxygen, which can be useful even when oxygen is insufficient in the outside air. However, the volume of oxygen tanks storing compressed oxygen is large and worn. Its performance and portability are inferior and it is not easy to wear it quickly in an emergency. Also, since the capacity of the air supplied from the oxygen tank is limited, the use time is very short and it cannot be useful when the evacuation time to a safe place is delayed. In addition, the air discharged when breathing with high-purity oxygen has a problem that the concentration of oxygen is higher than that of other places, which greatly reduces the number of breaths and the amount of exercise.

In addition, when a fire occurs along with power outages and dense smoke, it is difficult for evacuees to have a clear view. Therefore, a lighting device equipped with a flashlight or a gas mask equipped with a general lighting lamp has been provided.

The obstacle detection unit 58 made of a laser point or the like can quickly and easily grasp the evacuation path.

And in the early stages of a fire that does not have a lot of fumes or toxic gases, the oxygen concentration of the outside air is breathable environment, so that the first air breathing means 100 receives the purified air.

That is, the air purifying container 130, which is the primary breathing means 100, is opened by the primary side opening and closing member 133 provided at the inlet, and the secondary side opening and closing member 233 of the secondary breathing means 200 is blocked. The outside air is introduced into the air purifier 130, and the polluted air is purified by the air purifying filter 157, thereby receiving breathable air, and breathing with the supplied air to escape quickly. Done.

However, when a fire occurs, a toxic gas is spread and oxygen is deficient, and thus a situation in which breathing is difficult with the primary breathing means 100 occurs, the air purifying container 130 of the primary breathing means 100 ) Blocks the inflow of air by the primary side opening and closing member 133, and the secondary breathing means 200 is opened by the secondary side opening and closing member 233 of the oxygen supplier 230 so that oxygen is supplied. Breathing by the breathing means 200 is to be made.

The secondary breathing means 200 is to allow breathing to be performed through the oxygen supply 230 without inflow of external air, and occurs when the mask (M) wearer exhales in the process of breathing in the breathing part (B). The carbon dioxide is removed in a form that is filtered by the carbon dioxide removal filter 257 and then sent to the air storage unit 280, wherein the air storage unit 280 is nitrogen and other air required for breathing at the initial exhalation The components are sent and can be recycled.

Subsequently, inhalation in the breathing unit (B) is supplied with oxygen supplemented through the oxygen supply unit 230 and the carbon dioxide is removed at the time of exhalation and supplied with the air to breathe in an environment almost similar to the usual air breathing. That is, the oxygen required for breathing is supplied through the oxygen supplier 230 and the nitrogen and other air components necessary for the remaining breathing are obtained together through the exhalation that occurs during the initial breathing.

That is, when the mask (M) wearer inhales once the oxygen is supplied by the rebreather 250 provided in the lower side of the breathing portion (B) at the time of exhalation, unnecessary moisture and carbon dioxide generated in the breath is removed, including nitrogen Necessary air is stored in the air storage unit 280 to be supplied when re-breathing.
