Emergency gas supply device for escape

The present invention relates to a mask, and more particularly to an emergency air supply device for escape.

A large amount of smoke is generated during a fire, and a variety of hazardous gases such as carbon monoxide, hydrogen cyanide, and sulfur dioxide are generated. Therefore, in the escape process of the fire scene, most of the deaths and injuries are caused by heavy smoke, in view of the emergence of various types of escape aids.

For example, in the new patent case of "Escape Mask Structure" of the Republic of China Announcement No. M474534, the escape mask structure disclosed includes a cover portion and an air suction device. The cover portion has a front opening portion and an inner space, and the opening portion enables the inner space to communicate with the outside. The air suction device is disposed under the outer cover portion for drawing the gas outside the outer cover portion into the inner space. The air suction device is provided with a power supply portion and a filter portion for supplying power required for the air suction device to operate. The filter unit is disposed on the air suction device for filtering the gas sucked into the internal space by the air suction device. In this way, the outer cover portion is attached to the face of the user and covers the mouth and nose, and the user's nose and mouth are located in the inner space, and the air in the vicinity of the user's chest is extracted by the air suction device. After filtering, it is sucked into the internal space, and then discharged from the opening portion to achieve a gas flow circulation in the internal space for the user to breathe.

However, the opening portion of the escape mask structure has a tubular shape and faces forward, so that during the escape process, unless the air pressure in the outer cover portion is greater than the air pressure outside the outer cover portion, the gas outside the outer cover portion is still input through the opening portion. In the internal space, it is harmful to the user's breathing. If the extraction force of the air suction device is adjusted to extract more gas near the chest of the user into the internal space, the air pressure in the outer cover portion can be made larger than the air pressure outside the outer cover portion, thereby enabling the gas in the inner space to be It is discharged from the opening. However, it is worth noting that at the scene of the fire, once the dense smoke is dense, there will be only about 20 cm away from the ground. There will be residual air. The user often needs to adopt a crawling position to escape. The pumping device enhances horsepower. The pumping action is performed, and not only the gas in the internal space is discharged but not completely absorbed by the user, and the residual air near the ground is easily extracted, and the escape time of the user is shortened.

Therefore, it is an object of the present invention to provide an emergency air supply device for escape that provides oxygen for escape during a fire escape and that has an adjustable air supply amount.

Therefore, the emergency escape air supply device of the present invention comprises a cover unit and an oxygen supply unit. The cover unit has a breathing space, an air inlet and a vent. The oxygen supply unit is located outside the cover unit and detachably disposed at the air inlet hole. The oxygen supply unit includes a compressed gas cylinder filled with oxygen-containing gas and capable of inputting oxygen into the breathing space, and a A regulating element for adjusting the amount of gas entering the compressed gas cylinder.

The effect of the novel is that when the fire occurs, the cover unit is worn on the face, and the mouth and nose are located in the breathing space, and the oxygen supply unit is provided, so that the user can escape when the fire escapes. The required oxygen, and the operation of the adjusting element can also control the amount of gas supply, avoiding the waste of oxygen, thereby prolonging the escape time and increasing the chance of survival.

Referring to the first and second figures, a first embodiment of the emergency gas supply device for escape according to the present invention comprises a cover unit 1 and an oxygen supply unit 2. The cover unit 1 has a cover body 11 , an air inlet 12 disposed in the cover body 11 , a plurality of exhaust holes 13 disposed in the cover body 11 , and a gas seal 14 disposed at a periphery of the cover body 11 . And two elastic ropes 15 respectively disposed on opposite sides of the cover body 11 and two pairs of clamping members 16 disposed on the outer surface of the cover body 11 at intervals. A breathing space 111 is formed inside the cover body 11. In addition, the oxygen supply unit 2 includes a compressed gas cylinder 21 filled with oxygen-containing gas, and an adjusting member 22 for adjusting the gas intake amount of the compressed gas cylinder 21. The compressed gas cylinder 21 is detachably clamped and positioned outside the cover body 11 by the clamping member 16, and the compressed gas cylinder 21 has an air outlet portion 211 connected to the air inlet hole 12, and The oxygen-containing gas is introduced into the breathing space 111 through the intake port 12. The adjustment element 22 is a control valve.

Further, the emergency escape air supply device of the present invention further includes a whistle 3 which is provided at the air outlet portion 211 and is capable of emitting sound when the gas containing oxygen passes through the air outlet portion 211.

Referring to the first and second figures, in use, when a fire occurs, the user only needs to cover the cover body 11 on the face 41, and the nose and mouth are located in the breathing space 111, and the two tethers 15 respectively The airtight member 14 is closely attached to the user's face 41 so that the smoke at the scene of the fire cannot flow into the breathing space 111 from the gap between the cover body 11 and the face portion 41. At this time, the adjusting component 22 is turned on again and the adjusting operation is performed, so that the compressed gas cylinder 21 can output an appropriate amount of oxygen-containing gas through the air outlet portion 211, and is input into the breathing space 111 through the air inlet hole 12, so that the user can You can still breathe smoothly during the escape process. Moreover, by operating the adjusting component 22, the air supply amount can be controlled to avoid waste of oxygen, thereby prolonging the escape time and improving the survival probability. In addition, the exhaust gas exhaled by the user can be discharged outward through the vent holes 13 and is not circulated and sucked in the breathing space 111 of the cover body 11. In addition, by the arrangement of the whistle 3, the gas containing oxygen gas outputted by the compressed gas cylinder 21 through the gas outlet portion 211 simultaneously blows the whistle 3 when passing through the air inlet hole 12, so that the search and rescue personnel can be noticed. The location of the user.

Referring to the third embodiment, the second embodiment of the emergency air supply device for escape is the same as the first embodiment. The difference is that the cover unit 1 has a cover body 11 disposed thereon. A venting opening 13 and a check valve 17 disposed at the venting opening 13 for restricting gas from being unidirectionally unidirectionally passed through the venting opening 13 and outwardly. In use, this embodiment can also achieve the same effects as the first embodiment.

In summary, the emergency gas supply device for escape of the present invention is designed not only to be worn quickly, but also to provide oxygen required for the user to escape when the fire escapes, and can also be controlled by operating the adjusting member 22 The amount of gas, to avoid the waste of oxygen, which can prolong the escape time and increase the chance of survival. In addition, by the setting of the whistle 3, the oxygen outputted by the compressed gas cylinder 21 is simultaneously blown to the whistle 3 when inputting the air inlet hole 12, thereby attracting the search and rescue personnel to notice the position of the user, so that the user can Get rescued as soon as possible.

In view of the above description of the embodiments, the operation and use of the present invention and the effects of the present invention can be fully understood, but the above-described embodiments are merely preferred embodiments of the present invention, and the present invention cannot be limited thereto. The scope, that is, the simple equivalent changes and modifications made in accordance with the scope of the novel application and the novel description are all within the scope of the present invention.
