AI Technical Summary

Problems solved by technology

[0004] (1) It is impossible to maximize the utilization of fresh air in the air supply cylinder, and the service time of the air supply cylinder (the effective use time after a single common / standard air supply cylinder is filled with fresh air) is relatively short. In the case of high-intensity labor operations , the existing commonly used (standard) air supply cylinders are usually only usable for about 30 minutes after being filled with fresh air;
[0005] (2) The comfort during use is poor, especially when the user (such as a firefighter) wears a respirator to extinguish the fire, it is very easy to have poor breathing or even hypoxia;
[0006] (3) During use, it is easy to have difficulty in gas supply

Embodiment 1

[0051] Method of use of an air respirator, steps include:

[0052] Step 1, the user wears a good air respirator;

[0053] Step 2, during the exhalation process, the user first exhaled the gas to store the gas storage chamber, and the gas taken out of the user to the atmospheric environment; the first exhaled gas refers to the user's last time Inhalation and stored in the user trachea and / or the mouth, the rear exhaled gas refers to a gas that is inhaled inhaled in the user and exchanged by the user's lung gas;

[0054] Step 3, during the inhalation process, the user is exhaled and stored in the gas contained in the gas storage chamber.

[0055] As an optional scheme: During the inhalation process, the user's last exhaled and stored in the gas storage chamber first introduced the use of the use of the lungs and then introduced fresh air in the gas bottle into the user. Ministry, trachea and oral cavity; as an optional solution 2: In the inhalation process, the user's last exhaled...

Embodiment 2

[0070] See Figure 11 and Figure 12 The other air breathing apparatus employed includes a gas supply valve, the air supply valve is connected to the outer cover 8, and the outer cover 8 is provided with a mouth nose, which has a one-way channel A for use in the gas cylinder. The air (shown in number 123) is introduced into the mouth nose 9; the air breathing apparatus also has: channel B, for introducing the gas (numbered 121 shown) first exhaled into the storage member 2 The gas chamber is stored; one-way channel C is used to raise the gas (numbered 122 shown by the user) to the atmospheric environment; channel D is used to call the user once and store it in the gas storage chamber The gas (shown in number 120) is introduced into the mouth nose.

[0071] In this embodiment, the main structure and core idea are referred to in Example 1, which is different from that of Example 1 in that the nose mask 9 is provided with a one-way valve two 92, and the one-way valve 2 92 is used to co...

Embodiment 3

[0073] Method of use of an air respirator, steps include:

[0074] Step 1, the user wears a good air respirator;

[0075] Step 2, during the exhalation process, the user first exhaled the gas to store the gas storage chamber, and the gas taken out of the user to the atmospheric environment; the first exhaled gas refers to the user's last time Inhalation and stored in the user trachea and / or the mouth, the rear exhaled gas refers to a gas that is inhaled inhaled in the user and exchanged by the user's lung gas;

[0076] Step 3, during the inhalation process, the user is exhaled and stored in the gas contained in the gas storage chamber.

[0077] In the present embodiment, another air breathing apparatus employed includes a gas supply valve, a gas supply valve to connect an outer cover, a mouth nose is provided in the outer cover; the air breathing apparatus has an unidirectional channel A for use in a gas storage bottle. Introduction to the air introduction mouth nose hood; the a...

Abstract

The invention provides a using method of an air respirator. The using method comprises the steps that a user wears the air respirator; in the expiration process, a gas firstly expired by the user every time is introduced into the gas storage chamber to be stored, and the gas later expired by the user every time is exhausted to the atmospheric environment; the first exhaled gas refers to the gas inhaled by the user last time and stored in the trachea and/or oral cavity of the user, and the later exhaled gas refers to the gas inhaled by the user last time and subjected to gas exchange through the lung of the user; and in the inspiration process, the gas exhaled by the user last time and stored in the gas storage chamber is inhaled into the lung for reuse. After the scheme is adopted, the effective use time of an existing common air supply bottle filled with fresh air can be prolonged, and the comfort in the use process is good.

Description

Technical field [0001] The present invention relates to the use of an air respirator. Background technique [0002] At present, the air breathing apparatus commonly used on the market is primarily a product of the document CN202289250U or a similar product, which includes a housing, a spool in the housing, a valve core actuating mechanism, a valve, and a gas pipe. The nasal mask of the lower mouth is located in the outer cover, and the air supply is supplied to the gas cylinder. The valve core acting mechanism is used to drive the piston of the spool to achieve the user's gas supply, the air supply is completed. The piston is reset under spring action to achieve a stop gas, and an exhaust valve is also provided with an exhaust valve to distinguish a gas to an atmospheric environment. [0003] The existing air respirator and its air supply valve can be able to achieve gas supply, but it has the following problems: [0004] (1), the maximum use of fresh air in the air supply bottle...
