Description
Technical field
The present invention relates to gas mask technical fields, are specially a kind of gas mask for resolution experiment.
Background technology
In the modern times of concern health, the use of gas mask is increasingly extensive.In existing breathing mask, have general extensively
All over the advantages of using, but in the presence of toxic gas with strong points, the anti-toxicity tool of the gas mask generally used extensively
There is the shortcomings that barrier propterty difference even cannot reach effective protection, such as in experimentation is cleared up, the acid of various top pure grades is answered
With being essential, not only the respiratory apparatus to human body, respiratory tract etc. can generate fierceness to the acid vapor generated in experimentation
Stimulation, and the exposed organ such as eye to human body can also generate corrosivity, therefore, effectively prevent acid vapor from stimulating human body
It is particularly important；Second is that the mouth and nose guard plot size of the gas mask generally used is identical, and due to different experimenter's counterparts
The size requirements of nose guard plot are not quite similar, therefore it is uncomfortable that experimenter is caused to wear；In addition, it can be set on gas mask
There is the malicious box of filter, gas is filtered or is adsorbed, however, the replacement majority of the malicious box of filter is the malicious box integral replacing of filter, so as to make
Into waste.
The content of the invention
In consideration of it, the present invention provides a kind of for clearing up the gas mask of experiment, it is specially that one kind can solve difference
The shortcomings that experimenter is different to the size requirements of mouth and nose guard plot can prevent experimenter from being sucked in experimentation is cleared up
Toxic gas quickly can be replaced to ensure to filter in malicious box and done to the SDG adsorbent layers in the malicious box of filter and active carbon layer
Only, the gas mask of hygienic resolution experiment.This has simple in structure, easy to use, dry for the gas mask of resolution experiment
Net health, comfortable wearing and the advantages of effectively can prevent toxic gas from sucking.
On the basis of existing technology, the present invention provides a kind of for clearing up the gas mask of experiment, including cover body, institute
That states cover body is internally provided with silicagel pad A, silicagel pad B and silicagel pad C, silicagel pad A, silicagel pad B and triangular in shape point of silicagel pad C

Body is equipped with air entry, and air entry is embedded with breather cheek valve between silicagel pad A and silicagel pad B on the inner wall of air entry；It inhales
The outer rim of gas port is connected with thread barrel, and thread barrel is bolted with the malicious box of filter；Junction on the malicious box of filter with thread barrel is equipped with through hole A,
Filter poison box is made to be connected with the inside of cover body；Through hole B is additionally provided on the malicious box of filter；In the malicious box of filter along through hole A to the direction of through hole B successively
Equipped with dismountable bracket A and bracket B, SDG adsorbent layers are equipped in bracket A, active carbon layer is equipped in bracket B；The cover body
On be additionally provided with exhalation vents, exhalation vents are located at below air entry, and expiratory one-way valve is embedded on the inner wall of exhalation vents.
The cover body is internally provided with storage bag, and storage bag is located at the triangle that silicagel pad A, silicagel pad B and silicagel pad C are formed
Spontaneous heating bag is placed in shape region, in storage bag, when experimenter is when using gas mask, breathing can be effectively reduced and generate
Gas inside cover body because temperature change condenses into the amount of water droplet, keep dry and comfortable, hygienic inside mask.
The spontaneous heating bag includes raw material layer, gelatin layer and nonwoven layer, wherein, raw material layer is by iron, vermiculite, activity
The polymer of the synthesis such as charcoal, salt, water.
Goggles is connected with by stent on the outer wall of the cover body, goggles is located at the top of air entry, prevents toxic
Damage of the steam to eye simultaneously because goggles is located at the top of air entry, away from exhalation vents position, can prevent expiratory air
Body has an impact the observation visual angle of goggles, reduces since sight does not know the security risk to be formed.
The top and bottom of the cover body are respectively equipped with two metallic channels.
Shirr is installed in metallic channel, when wearing gas mask, gas mask is fixed on head by shirr.
Compared with prior art, beneficial effects of the present invention：The setting of silicagel pad A, silicagel pad B and silicagel pad C, make experiment
Personnel can be as needed, and the position for being about to silicagel pad A, silicagel pad B and silicagel pad C certainly is placed, and solves different experiments people
The shortcomings that member couple is different from mouth and nose guard plot size requirements, make experimenter have the advantages that comfortable wearing when in use；Filter poison
Box is threadedly coupled with the outer rim of air entry, can facilitate the fast quick-detach to the malicious box of filter and cover body；Along through hole A to through hole in the malicious box of filter
The dismountable bracket A and bracket B that the direction of B is set gradually, can facilitate in the SDG adsorbent layers in bracket A and bracket B
The fast quick-detach of active carbon layer, keep the clean, sanitary of the malicious box of filter, extend the service life of the malicious box of filter；SDG adsorbent layers can
The acid vapors effectively generated to resolution experiment are adsorbed, and reduce the amount that experimenter sucks noxious vapors, ensure experiment people
Member's safety；The setting of breather cheek valve and expiratory one-way valve, it is ensured that inside cover body according to the breathing of experimenter open or
It closes, further prevents injury of the noxious vapors to human body.
