Problems solved by technology

[0002] When a fire or toxic chemical leakage occurs, the greatest harm is poor breathing and poisonous smoke or gas. Existing personal protective equipment for firefighting is often equipped with masks and filters for filtering toxic gases. People's respiratory organs provide protection; but this approach is not enough. When danger occurs, escaped people still face difficulties in breathing, especially when the fire is large or the toxic smoke is thick, it is prone to hypoxia.

Embodiment 1

[0027] Please refer to Figure 1 to Figure 6 , This application provides a hand-held emergency breathing protection tank, including: a mask part 1, a hand-held part 2 and a bottom cover 3.

[0028] The mask portion 1 includes a breathing cavity 10 and a circulation cavity 18 arranged at the lower part of the breathing cavity 10, and the circulation cavity 18 is in communication with the breathing cavity 10. The hand-held part 2 is sleeved on the outside of the circulation cavity 18 and is connected to the mask part 1. The housing 21 of the hand-held part is rotatable, and the bottom of the hand-held part 2 is detachably connected to the bottom cover 3. The handpiece 2 is provided with a replaceable compressed air tank 20 that stores oxygen. The upper part of the compressed air tank 20 is provided with a rotary valve 22 which is connected to the handpiece housing 21. The rotary valve 22 can be rotated and opened as the handle housing 21 rotates. Such as image 3 with Figure 4 A...

Embodiment 2

[0038] This application also provides another hand-held emergency breathing protection tank, including: a mask part 1, a hand-held part 2 and a bottom cover 3. The mask part 1 includes a breathing chamber 10 and a circulation chamber 18 arranged at the lower part of the breathing chamber 10. The circulation chamber 18 is connected to the breathing chamber 10; the hand-held part 2 is sleeved outside the circulation chamber 18 and is detachably connected to the mask part 1. The handpiece 2 is provided with a replaceable compressed air tank 20 that stores oxygen. The compressed air tank 20 is in communication with the circulation chamber 18 through a retractable oxygen tube (not shown). The outer wall of the circulation chamber 18 is provided with an oxygen valve ( (Not shown), opening the oxygen valve can make the oxygen in the compressed air tank 20 flow into the breathing chamber 10 through the oxygen tube.

[0039] The difference from the first embodiment is that the hand-held e...

Abstract

A handheld emergency breathing canister comprises: a mask portion (1), a grip portion (2), and a base cover (3). The mask portion (1) comprises a breathing cavity (10) and a circulation cavity (18) disposed at a lower portion of the breathing cavity (10), and the circulation cavity (18) is in communication with the breathing cavity (10). The grip portion (2) is sleeved on an outer side of the circulation cavity (18), and a base portion thereof is detachably connected to the base cover (3). A replaceable compressed air canister (20) storing oxygen is disposed within the grip portion (2). An opening of the compressed air canister (20) is provided with a rotary valve (22) connected to a housing of the grip portion (2). The rotary valve (22) can rotate along with rotation of the housing of the grip portion (2) and then open, such that the compressed air canister (20) communicates with the circulation cavity (18). The mask portion (1) further comprises a breathable portion (11), and the location at which the breathable portion (1) communicates with the breathing cavity (10) is provided with a one-way check valve (12). The invention is for use in emergencies and hazardous situations, such as a fire or a toxic gas leak. The handheld emergency breathing canister prevents the inhalation of toxic smoke or gases, and further provides a safe and reliable supply of clean compressed air, thereby helping people safely evacuate from hazardous situations.

Description

Technical field [0001] The invention relates to the technical field of emergency devices, in particular to a handheld emergency breathing protection tank. Background technique [0002] When a fire or a toxic chemical leak occurs, the biggest harm is caused by poor breathing and toxic smoke or gas. Existing personal protective equipment for firefighting is often equipped with masks and filters for filtering toxic gases. People’s respiratory organs provide protection; however, this approach is not sufficient. When a danger occurs, people escaping still face difficulty in breathing, especially when the fire is large or the toxic smoke is thick, the phenomenon of hypoxia is prone to occur. Summary of the invention [0003] This application provides a handheld emergency breathing protection tank for emergency use in crisis scenarios such as fires and toxic gas leakage. The handheld emergency breathing protection tank can not only avoid the inhalation of toxic smoke or gas, but also pro...
