The hand-held part 2 is internally provided with a replaceable compressed air tank 20 storing oxygen, a tank opening at the upper part of the compressed air tank 20 is provided with a rotary valve 22, the rotary valve 22 is connected with a hand-held part shell 21, and the rotary valve 22 can rotate and open along with the rotation of the hand-held part shell 21. As shown in fig. 3 and 4, after the rotary valve 22 is opened by rotating the hand-held housing 21, the compressed air tank 20 is communicated with the circulation chamber 18, and since the circulation chamber 18 is communicated with the breathing chamber 10, oxygen in the compressed air tank 20 flows upwards from the tank opening to the breathing chamber 10 for the user to breathe. The mask portion 1 further includes: the department that ventilation portion 11, ventilation portion 11 and breathing cavity are linked together is provided with check valve 12, ventilation portion 11 still is provided with bleeder vent 14, as shown in fig. 5 and fig. 6, check valve 12 only can open towards 14 directions of bleeder vent one-way to when realizing discharging user's expired gas breathing cavity 10, still can prevent outside gas to get into breathing cavity 10 in, can be in the conflagration emergence, dangerous scenes such as toxic gas leakage, avoid the user to inhale toxic smog or gas.

Therefore, as the replaceable compressed air tank 20 storing oxygen is arranged in the handheld part 2, the handheld emergency breathing protective tank can provide oxygen required by breathing for a user after the rotary valve 22 is opened, and the one-way opening check valve 12 is arranged in the mask part 1, so that the user is prevented from inhaling toxic smoke or gas; the oxygen of compressed air jar 20 storage can help the user to escape the dangerous scene safely, because the bottom of handheld portion 2 can be dismantled with bottom 3 and be connected, the compressed air jar 20 that can conveniently change for the emergent breathing protection jar of hand-held type repeatedly usable.

In some embodiments, an air cover 23 is further disposed in the circulation cavity 18 above the opening of the compressed air tank 20 and the rotary valve 22, and an ejector pin 13 is further disposed on an inner wall of the circulation cavity 18, and the ejector pin 13 is connected with the air cover 23 and used for pressing the air cover 23, so that it can be ensured that oxygen in the compressed air tank 20 flows upwards only when the rotary valve 22 is opened, a sealing effect is achieved, and oxygen leakage is prevented.

In some embodiments, the shape of the housing 21 of the handpiece includes, but is not limited to, cylindrical, square, and other shapes that facilitate rotation and gripping.

In some embodiments, the outer wall of the housing 21 of the hand-held portion is provided with anti-slip threads or hand-shaped grooves for easy gripping.

In some embodiments, the outer wall of the housing 21 of the hand-held portion is provided with a fluorescent strip 24 to indicate to the user the position of the hand-held emergency breathing protective canister in the event of insufficient lighting.

In some embodiments, as shown in fig. 7, the bottom of the hand-held portion 2 is screwed to the bottom cover 3, and the bottom cover 3 is unscrewed to replace the compressed air tank 20.

In some embodiments, the bottom cover 3 is provided with an LED lamp ring 31 and a lamp switch 32, and the lamp switch 32 is turned on, so that the LED lamp ring 31 can provide ground illumination for a user when the user uses the hand-held emergency breathing protective tank, thereby facilitating the escape of the user by routing.

In some embodiments, the mask portion 1 is further provided with a head fixation strap (not shown) for fixing the mask portion 1 on the head for breathing.

Example two:

the application still provides emergent respiratory protection jar of another kind of hand-held type, include: a mask part 1, a hand-held part 2 and a bottom cover 3. The mask part 1 comprises 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 communicated with the breathing cavity 10; the handheld part 2 is sleeved outside the circulation cavity 18 and detachably connected with the mask part 1. The hand-held part 2 is internally provided with a replaceable compressed air tank 20 storing oxygen, the compressed air tank 20 is communicated with the circulation cavity 18 through a telescopic oxygen tube (not shown), and the outer wall of the circulation cavity 18 is provided with an oxygen valve (not shown) which is opened so that the oxygen in the compressed air tank 20 flows into the breathing cavity 10 through the oxygen tube.

The difference from the first embodiment is that the hand-held emergency breathing protective cup of the present embodiment can be used not only by holding the whole body with hands as in the first embodiment, but also by detaching and separating the hand-held part 2 and the mask part 1. The retractable oxygen tube is housed in the circulation chamber 18 as an oxygen circulation duct when used as a whole, and serves as an oxygen circulation duct as well as a connection line between the hand grip 2 and the mask unit 1 when used as a separate body. Therefore, the handheld emergency breathing protection tank of the embodiment is convenient to use and can be recycled, and the handheld emergency breathing protection tank can be used as outdoor equipment and used as a temporary oxygen tank.

In some embodiments, the mask portion 1 may further include a head fixing strap, which may be used to fix the mask portion 1 on the head for breathing and release both hands. Particularly, when the hand-held unit 2 is used separately outdoors, the hand-held unit 2 provided with the compressed air tank 20 can be placed in a backpack, and both hands can be released.

The present invention has been described in terms of specific examples, which are provided to aid understanding of the invention and are not intended to be limiting. For a person skilled in the art to which the invention pertains, several simple deductions, modifications or substitutions may be made according to the idea of the invention.
