[0002] Fire escape breathing apparatus is a device specially designed to protect the respiratory system in emergency situations such as fires, including escape breathing masks, self-rescue respirators, escape respirators, etc. Their function is to provide clean air or oxygen, help users escape safely in an environment full of smoke and toxic gases, and reduce the risk of respiratory injury.

[0003] At present, some fire escape breathing devices are designed for single use and cannot be reused. This is mainly because in an emergency, time is of the essence, and disposable devices can provide faster and more convenient respiratory protection. However, this also brings about the problem of waste of resources. In addition, there are indeed some deficiencies in head care for fire escape breathing devices. Although these devices can help users breathe, they do not completely solve the problem of head protection. At the fire scene, head protection is also crucial, because smoke and toxic gases can not only cause damage to the respiratory system, but also may cause damage to the eyes, skin, hair and other parts.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Combined with Figure 1 A fire escape emergency breathing device includes a breathing hood 1 and a gas supply bottle. The side wall of the breathing hood 1 is connected with goggles 14, which can effectively protect the user's eyes and facilitate the user to observe the surrounding environment for escape. A protective shoulder cover 2 is connected below the breathing hood 1, and a fireproof coating is provided on the protective shoulder cover 2, which has a good fireproof effect and good protection.

[0024] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 A breathing tube 3 is connected between the air supply cylinder and the breathing hood 1, and the air supply cylinder includes an upper shell 4 and a lower shell 5, the upper shell 4 and the lower shell 5 are fixedly connected and internally communicated, a piston 6 is provided in the upper shell 4 near the breathing tube 3 and below the breathing tube 3, a spring 7 is connected between the piston 6 and the lower wall of the upper shell 4, and a quick-pull structure for fixing the piston 6 is connected to the upper shell 4, and the quick-pull structure includes a push rod 15 connected above the piston 6, the upper end of the push rod 15 slides out of the upper shell 4, and a fixing seat 16 is connected above the upper shell 4, and the push rod 15 and the fixing seat 16 are fixed by a launch belt 17 that slides through the push rod 15 and the fixing seat 16, and the launch belt 17 slides through the push rod 15 and the fixing seat 16, so that the piston 6 can be pulled out quickly and conveniently to work, which is suitable for emergency escape. The push rod 15 is a T-shaped rod, which can ensure that the upper end of the push rod 15 is always located above the fixing seat 16, and it is convenient to move the push rod 15 to a suitable height to install the launch belt 17, thereby realizing repeated use. A handle 18 is connected to one side of the launch belt 17 to facilitate quick pulling out of the launch belt 17.

[0025] Combined with Figure 2 , Attachment Figure 4A safety valve 8 is connected to the connection point between the lower shell 5 and the upper shell 4, an inflation joint 9 and an alarm whistle 10 are connected to the side wall of the lower shell 5, a ejector pin 11 is provided in the inflation joint 9, the ejector pin 11 and the alarm whistle 10 are connected to the inside of the lower shell 5, a pressure gauge 12 is connected to the lower shell 5, and a connecting pipe 13 is integrally formed at the bottom of the lower shell 5.

[0026] The specific implementation mode of the utility model is as follows: connect the external compressed air bottle to the connecting pipe 13. When in use, check the state of the pressure gauge 12 to ensure that the device is in a usable state, put the breathing hood 1 on the head, put the goggles 14 on the front side, and cover the neck and shoulders with the protective shoulder cover 2. The environment can be observed through the goggles 14, pull down the transmitting belt 17, open the safety valve 8, and the gas in the compressed air bottle enters the upper shell 4 through the lower shell 5, and pushes the piston 6 to move upward. At the same time, the push rod 15 moves upward in coordination, and the spring 7 stretches until the piston 6 moves above the breathing tube 3. The gas can enter the breathing hood 1 through the breathing tube 3 to help the user breathe. When the air in the compressed air bottle is almost exhausted, the pressure in the upper shell 4 and the lower shell 5 decreases, and the piston 6 moves down and resets under the action of the spring 7. The remaining gas in the compressed air bottle is discharged through the alarm whistle 10, and the alarm whistle 10 sounds an alarm to remind that the compressed air is insufficient. In case of emergency escape, the external compressed air bottle can be directly replaced. If it is in a safe environment, the safety valve 8 can be closed, the external inflation device is connected to the inflation connector 9, and tightly connected to the ejector pin 11, and the inflation device is used to inflate the compressed air bottle, and the push rod 15 is pushed, and the new launch belt 17 is passed through the push rod 15 and the fixing seat 16 for fixing, which is convenient for secondary use.
