An air supply valve is arranged at an air outlet of the face mask 2-1, when a person inhales air, the air supply valve is automatically opened under the action of negative pressure to be breathed by the person, and the air supply valve has the functions of supplying air and positive pressure according to requirements, namely, when the person inhales air, the air enters the face mask 2-1, and meanwhile, the pressure in the face mask 2-1 is kept higher than the pressure of the ambient atmosphere; when the person exhales, the air supply valve does not supply air, and the exhaled air is exhausted from the exhalation valve on the mask 2-1, so that a reciprocating breathing cycle process is formed according to the rule. In the breathing process, people cannot suck the gas outside the gas supply equipment, and when the mask 2-1 is not used, the gas in the gas supply equipment cannot leak.
As shown in fig. 7-8, a folding seat 2-8 is also provided on the air supply control cabinet below the mask storage box 2-7. After the rescue personnel sit down, the gas consumption in the gas supply equipment can be reduced.
It is noted that some of the structures may be selected differently than the specific examples given above. The first magnet 3 and the second magnet 4 may be magnets of other shapes; and the like, which can be made by those skilled in the art based on their basic skills based on an understanding of the inventive concept, and are not to be taken as an example herein.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention, and these changes and modifications are to be considered as the protection scope of the invention.
