Vehicle-mounted self-rescue oxygen unit

Abstract

The invention discloses a vehicle-mounted self-rescue oxygen device, which includes an oxygen bottle, an electric bottle head valve, an oxygen delivery pipe, a control box, a manual trigger switch, a primary oxygen decompression valve, a decompression pipeline, an oxygen shunt structure, a secondary oxygen decompression Pressure valve, metal bellows, suction head, oxygenation valve and wiring harness, one end of the oxygen cylinder is connected to the oxygenation valve, the other end is connected to the electric bottle head valve, and the electric bottle head valve is connected to the primary oxygen pressure reducing valve through the oxygen delivery pipe , the primary oxygen decompression valve is connected to the decompression pipeline, the decompression pipeline is connected to the oxygen shunt structure, the oxygen shunt structure is connected to the secondary oxygen decompression valve, and the secondary oxygen decompression valve is connected to the suction head through a metal bellows Each of the suction heads is equipped with a small switch, the small switch is connected with the control box through the wire harness, and the control box is also connected with the electric bottle head valve and the manual trigger switch through the wire harness. The invention realizes emergency breathing when the automobile falls into water, and provides valuable time for self-rescue and waiting for rescue.

Description

technical field [0001] The invention relates to an oxygen breathing device, in particular to a vehicle-mounted self-rescue oxygen device, belonging to the technical field of self-rescue oxygen inhalation devices. Background technique [0002] If the car encounters an emergency and accidentally falls into the water, water will quickly enter the car. At this time, it is difficult to open the door to escape due to the pressure difference between the inside and outside. When the car is filled with water, the pressure difference between the inside and outside is balanced, and the door can be opened. , but in the process, due to lack of oxygen, it will bring great obstacles to escape or wait for rescue. [0003] In the prior art, it is possible to carry oxygen cylinders similar to diving, and there may be more than one person in the vehicle that falls into the water, but it needs to store enough oxygen for 4 people for 10-20 minutes, and press more air into the limited volume of t...

[0002] If the car encounters an emergency and accidentally falls into the water, water will quickly enter the car. At this time, it is difficult to open the door to escape due to the pressure difference between the inside and outside. When the car is filled with water, the pressure difference between the inside and outside is balanced, and the door can be opened. , but in the process, due to lack of oxygen, it will bring great obstacles to escape or wait for rescue

[0003] In the prior art, it is possible to carry oxygen cylinders similar to diving, and there may be more than one person in the vehicle that falls into the water, but it needs to store enough oxygen for 4 people for 10-20 minutes, and press more air into the limited volume of the oxygen cylinder. The internal pressure of the oxygen cylinder is relatively large

In addition, because people are more flustered in an emergency, more complicated operations are inconvenient

For the above-mentioned vehicle immersion breathing device, there is no matching device
