The protective layer comprises a cooling layer, a reinforcing layer and a heat insulation layer which are sequentially arranged from inside to outside, and a coolant is arranged in the cooling layer and used for absorbing heat generated by the oxygen tank 7 and reducing the temperature of oxygen; the reinforcing layer is used for buffering external impact and preventing the cooling layer from being damaged to cause leakage of the coolant and influence the oxygen generating agent to generate chemical reaction; the heat insulation layer is made of heat insulation materials, so that a user can be prevented from being scalded in the wearing process.

The two sides of the oxygen passage pipe 11 are symmetrically provided with the reticular clapboards 13, the oxygen generating agent is separated by the reticular clapboards 13, the contact area of the oxygen generating agent and carbon dioxide is enlarged, and the oxygen generating agent is fully reacted. The first piston 14 is further arranged at the air outlet 10, so that oxygen can enter the air storage bag 2 only by taking off the first piston 14 when the respirator is used, but sometimes the respirator is not supplied with oxygen timely because a user wears the respirator to forget to take off the first piston 14 under the condition of being in a hurry such as fire escape. To avoid this, the embodiment of the present invention connects the first piston 14 to the exhaust valve 8 through the pull string 15. The air storage bag 2 is in a folded state when not used, the traction rope 15 is in a loose state at the time, when a user unfolds the folded air storage bag 2 for use, the traction rope 15 is tightened and pulls out the first piston 14, the respirator can be put into use when the air storage bag 2 is unfolded, operation steps are reduced, and the use is more convenient.

Because the reaction of the oxygen generating agent and the carbon dioxide needs a short time to generate enough oxygen for the user to use, namely the oxygen tank 7 has an oxygen generating lag phase, the user needs to breathe with a large mouth to provide enough carbon dioxide in the oxygen generating lag phase, and in order to avoid the user from inhaling a large amount of toxic gas and smoke in the oxygen generating lag phase, the embodiment of the utility model also provides an oxygen bottle jack 16 at the bottom of the oxygen tank 7, and an oxygen bottle 17 is arranged in the oxygen tank 7, and the oxygen is supplied to the user in the oxygen generating lag phase through the oxygen bottle 17; the oxygen bottle 17 is arranged in the oxygen tank 7 in an inverted mode, the air outlet of the oxygen bottle 17 extends out of the oxygen bottle 17 through the oxygen bottle jack 16, and a user does not need to breathe with a large mouth in the delayed period of the regenerated oxygen, so that the inhalation of toxic gas and toxic smoke is reduced. A pull rod 18 is further arranged at the air outlet of the oxygen cylinder 17; the pull rod 18 is connected with the exhaust valve 8 through another pull rope 15, namely as shown in fig. 6, so that the pull rod 18 is the same as the first piston 14, and is taken down when the air storage bag 2 is unfolded, and the oxygen cylinder 17 is immediately put into use; or is connected with the first piston 14 by a hook 19, i.e. when the first piston 14 is removed, the pull rod 18 is removed by the gravity of the first piston 14, as shown in fig. 5. As shown in fig. 5, when the hook 19 is used to connect the first piston 14 and the pull rod 18, it is impossible to connect the exhaust valve 8 and the pull rod 18 by using only one pull rope 15 alone because the oxygen cylinder 17 has a small volume and the pull rod 18 used has a light weight, whereas the first piston 14 has a larger weight than the pull rod 18, and it is difficult to remove the first piston 14 by the gravity of the pull rod 18 when the pull rod 18 is removed by the pull rope 15 when the air bag 2 is deployed. Similarly, when the pull rod 18 is connected to the exhaust valve 8 by the pull rope 15 in order to ensure that the pull rod 18 can be smoothly removed, the length of the pull rope 15 between the pull rod 18 and the exhaust valve 8 is not more than 1/2 of the height from the bottom of the oxygen tank 7 to the bottom of the air bag 2 after the air bag 2 is unfolded.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
