39 outflow after, the second sliding block 53 second spring 52 elastic force lower slider, the second sliding block 53 by hydraulic pipeline 33 drive the 4th
In the 5th sliding slot 31 of 32 retraction of sliding block, limiting slot 30 and Four-slider 32 no longer limit the sliding scale of slide bar 15；
When not using disposable breathing mask temporarily, slide bar 15 stretches out first sliding groove 49, and groove 29 is connected to the 6th sliding slot 26, nose bar 28
It protrudes into groove 29,15 close pinhole 20 of slide bar, disposable breathing mask is in folded state；
When needing to abandon disposable breathing mask, due to opening a mask, limiting slot 30 and Four-slider 32 no longer limit cunning
The sliding scale of bar 15, when the mask in folded state is folded inward again, third spring 27 is pressed into the 6th and slided by slide bar 15
In slot 26, the protruding more distances of slide bar 15, the no longer close pinhole 20 of slide bar 15, elastic force of the needle tubing 21 in the 4th spring 23
Lower upward sliding is acted on, needle tubing 21 punctures hydrochloric acid bag 34, and dilute hydrochloric acid enters dye layer 12 and mistake by pin hole 20 and staining trough 25
In filtering layer 13, carries out simple disinfection and destroy.
In conclusion the disposable breathing mask that one kind of the invention is simply destroyed is easy to operate clear, it is quick on the draw, safely may be used
It leans on；Meanwhile the device of the invention is vdiverse in function, effect is intuitively obvious, practical.
The above, the specific embodiment only invented, but invent protection scope be not limited thereto, it is any without
The change or replacement that creative work is expected are crossed, should all be covered within the protection scope of invention.
