Novel oxygen breathing apparatus

Abstract

The invention discloses a novel oxygen breathing apparatus which comprises a breathing mask and a toolkit. The novel oxygen breathing apparatus is characterized in that the breathing mask is connectedto the toolkit through a gas guide tube, wherein the toolkit is further equipped with a waistband; the waistband is provided with a double-buckle belt regulating structure, and lifting rings are arranged at the two sides of the waistband; the toolkit is made of a flame resistant material; a metal shell is further arranged at the outer side of the toolkit; an oxygen gas generating device, a gas filter device and a gas storage bag are arranged in an inner cavity of the toolkit; the oxygen gas generating device, the gas filter device and the gas storage bag are sequentially connected through a pipeline; and an oxygen producer is further arranged in the oxygen gas generating device. With the adoption of the technical scheme, the toolkit is made of the flame resistant material, and the metal shell is further arranged at the outer side of the toolkit; and the oxygen gas generating device, the gas filter device and the gas storage bag are arranged in the inner cavity of the toolkit, so thatan operator relieves load, eliminates high-pressure hidden danger and improves using efficiency.

Description

technical field [0001] The invention relates to a respirator, in particular to a novel oxygen respirator. Background technique [0002] Oxygen respirator, the respiratory system is isolated from the outside world, and the instrument forms an internal circulation with the human respiratory system to protect the user's respiratory system from external influences. [0003] However, in the prior art, since oxygen respirators are all sourced from bottled compressed air, all the gas required in the use process is supplied by compressed air, and the exhaust gas is discharged to the outside after a single cycle, increasing the loss of oxygen, and the compressed air The gas storage cylinder is a pressure vessel, and the pressure vessel is relatively heavy. If the gas storage cylinder leaks or explodes, it will hurt the user, and the inner liner will react slowly with the oxygen in the gas storage cylinder under high pressure conditions, and at the same time reduce the pressure in the...

[0003] However, in the prior art, since oxygen respirators are all sourced from bottled compressed air, all the gas required in the use process is supplied by compressed air, and the exhaust gas is discharged to the outside after a single cycle, increasing the loss of oxygen, and the compressed air The gas storage cylinder is a pressure vessel, and the pressure vessel is relatively heavy. If the gas storage cylinder leaks or explodes, it will hurt the user, and the inner liner will react slowly with the oxygen in the gas storage cylinder under high pressure conditions, and at the same time reduce the pressure in the air. Oxygen content renders the compressed gas unusable
