The actuating pin 174 is connected to the hood unit 150 to operate, where the meaning of the connection means that it is connected to the hood unit 150 or the wear unit 180 provided in the hood unit 150 to be operated. As a result, the operation pin 174 is removed when the hood unit 150 is unfolded or when the wearing unit 180 is operated to supply oxygen of the compressed oxygen tank 160.

Of course, the operation pin 174 can also be removed by the user gripping directly.

In addition, the cap C is provided inside the respirator 110 to cover the discharge port 112, and may be removed by an unfolding operation of the hood 150.

Hereinafter, the operation of the simple breathing apparatus according to the first embodiment of the present invention having the above structure will be described.

When a fire or explosion occurs inside a building or subway, the user may wear an easy breathing apparatus 100 and evacuate, thereby preventing an accident.

When the wearer wears the hood part 150, the actuating pin 174 is removed by tightening the wearing part 180 provided in the hood part 150, and the valve 172 is removed by removing the actuating pin 174. ) Is opened, oxygen of the compressed oxygen tank 160 is supplied to the hood (150).

Wearing the hood unit 150 is completed by using the hood unit 150 on the wearer's head upside down, and fixing the breathing unit 110 to the wearer's face using the wearing unit 180. At this time, the lower end of the hood unit 150 is provided with a sealing member 157 surrounding the wearer's neck, the inside of the hood unit 150 is sealed, oxygen of the compressed oxygen tank 160 supplied to the hood unit 150 By this, the wearer is able to take an initial breath.

In addition, the wearer may breathe through the breathing unit 110.

Due to the wearer's breathing, the carbon dioxide and moisture are moved to the reaction control unit 120 through the discharge port 112, the breath of the wearer in the reaction control unit 120 is delayed in the flow is delivered to the oxygen generator 130. .

This is because the reaction control unit 120 is composed of the first passage 122, the expansion member 124, the second passage 124, the flow rate of respiration by the expansion member 124 having a wider cross-sectional area than the first passage 122 Slowing, the slowed flow of breath is to be delivered to the oxygen generator 130.

Since the slow flow of breath is supplied to the oxygen generator 130, the reaction efficiency of the reaction unit 132 may be improved to generate a large amount of oxygen.

The generated oxygen is transferred to and stored in the temperature reduction unit 140.

Since the oxygen generated by the oxygen generator 130 is stored in the temperature reduction unit 140 without being directly delivered to the wearer, the high temperature of the generated oxygen is lowered to a temperature suitable for the wearer to breathe.

This is possible because oxygen may be stored in the temperature reducing unit 140 by the auxiliary check valve 145 provided between the temperature reducing unit 140 and the hood unit 150.

The oxygen stored in the temperature reduction unit 140 is supplied into the hood unit 150, and the wearer may breathe through the inlet 114 of the breathing unit 110.

In addition, the lip member 115 may be provided in the respirator 110 as illustrated in FIGS. 9 and 10 to prevent the residual moisture and carbon dioxide in the respirator 110 to provide smooth breathing. Can be.

The wearer may breathe through the breathing unit 210.

The carbon dioxide and moisture are moved to the reaction control unit 220 by the wearer's breathing, the breath of the wearer in the reaction control unit 220 is delayed in the flow is delivered to the oxygen generator 230.

This is because the reaction control unit 220 is composed of the first passage 222, the expansion member 224, the second passage 226, the flow rate of respiration by the expansion member 224 wider cross-sectional area than the first passage 222 Slowed, the flow is slow breath is to be delivered to the oxygen generator 230.

Since the slow breath flow is supplied to the oxygen generating unit 230, the reaction efficiency in the reaction unit can be improved to generate a lot of oxygen.

Oxygen generated by the oxygen generator 230 is supplied to a space between the inner hood member 252 and the outer hood member 254 serving as an oxygen bag.

In addition, the oxygen delivered to the space between the inner hood member 252 and the outer hood member 254 is supplied to the inlet 214 of the breathing unit 210 through the oxygen supply passage 255 so that the wearer easily breathes. You can do it.

That is, since oxygen is stored in the space between the inner hood member 252 and the outer hood member 254, the oxygen of the high temperature generated by the oxygen generator 230 is lowered to allow the wearer to breathe smoothly.

This is possible because the oxygen supply passage 255 is provided with an auxiliary check valve 256 to store oxygen in the space between the inner hood member 252 and the outer hood member 254.

In addition, as shown in FIG. 15 and FIG. 16, the temperature reducing unit 240 is provided between the oxygen generating unit 230 and the hood unit 250, so that the temperature of the oxygen is primarily caused by the temperature reducing unit 240. It can be lowered, and the temperature of the oxygen can be lowered in the space formed by the inner hood member 252 and the outer hood member 254 secondary to provide a good temperature oxygen to breathe.

As described above, according to the simple breathing apparatus according to the present invention, the first breathing by the oxygen of the compressed oxygen tank, the breather of the wearer generates oxygen through the oxygen generator, so that it is possible to continue breathing in emergency situations without panic Can cope

In addition, since the carbon dioxide and moisture generated by the wearer's breath is accurately transmitted by the lip member, it is possible to prevent the remaining of carbon dioxide and moisture in the breathing part, and delay the flow of carbon dioxide and moisture by the reaction control part to generate oxygen. By transmitting to, the reaction efficiency of the oxygen generator can be improved to implement a highly reliable product.

In addition, by supplying the high temperature oxygen generated from the oxygen generating unit through the temperature reducing unit, it is possible to provide the oxygen of the temperature good to breathe.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
