Embodiment 2

[0029] Embodiment two, the difference with embodiment one is:

[0030] see image 3The headgear 2 is provided with a head section 21 and a neck section 22 sleeved on the user's neck. A buffer airbag 23 is arranged inside the head section 21 . The cushion airbag 23 constitutes the inner surface layer of the portion of the head section other than the front side. The neck section is a flexible structure. The neck section is provided with a neck section retracting mechanism 5 . There are two retracting mechanisms for the neck section and they are distributed along the up and down directions. The neck section retracting mechanism includes a suspension ring 51 distributed along the neck section circumferential direction, a rope untightening mechanism and a rope 52 threaded in the suspension ring. The air inlet 27 is provided at the front end of the mask 3 . The front end of the cover is also provided with a one-way valve 6 for air outlet.

[0031] see Figure 4 , The mask is...

Abstract

The invention relates to fire-fighting equipment, and discloses positive pressure air breathing apparatus achieving inflation in place at one step. The positive pressure air breathing apparatus comprises a head hood and an air bottle. A valve is arranged at the upper end of the air bottle. A mask is arranged in the head hood. An air inlet communicating with the head hood is arranged on the mask. The valve is provided with a pressure limiting valve, wherein the pressure limiting valve is opened when the air pressure in the air bottle is above the set value. An air outlet of the valve is connected together with the air inlet through a rubber pipe. By means of the positive pressure air breathing apparatus achieving inflation in place at one step, the air pressure can achieve the set value through one-time filling, and the problem that in existing positive pressure air breathing apparatus, air pressure cannot achieve the set value through one-time filling is solved.

Description

[0001] This application is an application number 2018103089299, with an application date of April 9, 2018, and a divisional application of the application titled "Positive pressure air respirator with one-step inflatable inflation". technical field [0002] The invention relates to fire-fighting equipment, in particular to a positive-pressure air respirator that can be inflated in one step. Background technique [0003] The positive pressure-eliminating air respirator is an isolated respirator that uses compressed air as the breathing air source. The compressed air used is stored in the self-contained air storage bottle (hereinafter referred to as the air bottle), and the air supply method is positive. Pressure type, that is, when a person wears a respirator to breathe, the entire respiratory system is always isolated from the outside world and the internal pressure is higher than the external environment pressure. During the breathing process, the toxic and harmful gases fro...
