452 are entrusted, the middle part of support belt 452 is connected on the lateral surface of fitting frame 1, and the left end of support belt 452 is mounted on limit sleeve 3 and sets
On the rectangular hollow base set, when specific works, the support belt 452 on rotating drum 45 can play supporting role to rotating drum 45,
It prevents personnel under strenuous exercise, mask is caused to be subjected to displacement.
Breathing mask of the present invention use process is as follows:
Step 1: the wearing of mask, fitting frame 1 is attached to the face of human body, and the upper end protrusion of fitting frame 1 can touch use
The nose of personnel, so that fitting frame 1 and the face of personnel fit, the rectangular hollow cover for seat of 3 left end of limit sleeve is in personnel later
The back side of head on, the rear necks that buckle set 2 is locked in personnel enable personnel easily to take mask, on rotating drum 45
Support belt 452 can play supporting role to rotating drum 45, prevent personnel under strenuous exercise, mask is caused to be subjected to displacement；
Step 2: personnel's air-breathing and exhale, when personnel carry out air-breathing, gas by the air inlet of 47 right end of inlet chamber into
Enter, gas, which successively passes through between rotating drum 45, position-limited rack 46 and clamping mechanism 44, is placed with filter cotton, test chamber 41, dust inspection
Survey machine 42 can detect the dust in air, and prevent filter cotton from using causes the dust in air can not be by mistake too long
Filter, when the air in test chamber 41 contains dust, dust alarm lamp 43 will do it alarm, remind personnel to filter cotton progress and
Shi Genghuan, gas can be drawn when entering in fitting frame 1 for personnel, and when personnel exhale, gas can be arranged from fitting frame 1
Air cushion at be discharged；
Step 3: the replacement of filter cotton, filter cotton can be stuck on position-limited rack 46 by clamping mechanism 44, prevent position-limited rack 46
The dust for having channel of leaking out to cause impurity between filter cotton carries out in test chamber 41, and squeezing guide way 445 is to be inclined outwardly,
Filter cotton is smoothed out with the fingers directly under the action of guide way spring 446 so that squeezing guide way 445, the right end of filter cotton can be tightly attached to limit
On the left side of position frame 46, when needing to replace filter cotton, rotating drum 45 is removed, it is artificial to push on push frame 447
Push protrusion, to be replaced to filter cotton；
Step 4: the oxygen supply of external oxygenerator, when containing the toxic gases such as carbon monoxide in the air of sucking, gas report
Warning lamp 411 can alarm, and manually push locking branch 49 to the left, one-way mechanism 48 is enabled to block the unidirectional of rotating drum 45
Hole, prevents the sucking of toxic gas, controls external oxygenerator at this time and is slowly conveyed oxygen, and oxygen is from oxygen hose 411
Into in test chamber 41, test chamber 41 and the pressure of rotating drum 45 be will increase, so that one-way mechanism 48 is thoroughly closed, thus personnel
When in air without toxic gas, lock hook 492 can be pulled outward, so that lock hook with oxygen intake, the safety of protection staff
492 separate with hook housing 493 and are returned to initial position under the action of being classified as spring 486, while controlling external oxygenerator and stopping
It only supplies oxygen, so as to improve the cruising ability of external oxygenerator；The present invention, which is realized, to be sucked dust in personnel or has poison gas
The function of being warned when body, when solving the use of existing breathing mask existing breathing mask wear it is difficult, can not be in personnel
When sucking dust automatic alarm, breathing mask persistently supply oxygen cause its service life is short, breathing mask unidirectional pad leakproofness is poor,
The problems such as can not carrying out the switching of natural aspiration and oxygen supply, purpose is reached.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and only illustrating for the description in above embodiments and description is of the invention
Principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these change and change
Into all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent
It defines.
