Description
Affiliated technical field:
The utility model relates to a kind of making and wears staff and extraneous contamination air insulated, and the anti-biochemical tool comprehensively in the big visual field of clean gas is provided by canister.Belong to labour protection protective articles field.
Background technology:
Existing breathing mask has helmet-type, hood type, every filter formula etc., because the Smoke prevention gas defence performance and the mask itself of breathing mask should in light weightly, easy to carry and use be a pair of contradiction, the professional can't thoroughly address this problem at present, usually can only be according to different application scenarios, individual event ground solves application problem.De Lege profile tool as Germany, weight reaches 1.5 kilograms, price is very expensive again, though and for example China's patent 90203566.5 has solved expensive problem, but because apnea valve, active carbon directly contacts with breath, its gas defence effect is affected, and above-mentioned two technology all can not be prevented carbon monoxide.
And for example publication number is that 1173139 patent has been announced a kind of breathing mask, and it mainly is made up of face part, compressible filter parts and the fixture that is connected face part and filter element.Wherein fixture is provided with a wall with the circumferential surface frictional engagement of filter element, is used for forming airtight conditions on this circumferential surface, so that filter element is fixed in the fixture.Filter element mainly is made up of filtering agent, needs often to change.Because this technology adopts the fixing mode of frictional engagement, so dismounting inconvenience; Repeatedly after the dismounting, each parts damages easily, and its sealing can be affected, the easy fatigue aging of the bending part of plastic components.And only be provided with a venthole on its face part, breathe smooth and easy inadequately when face shield uses.
At present, China's sandstorm happens occasionally, and the disease of influenza and so on is also very rampant, and fire, a large amount of toxic and harmfuls that industrial production produced are all taking place at any time to the mankind's injury in addition, and always there is defective in existing breathing mask owing to there is above problem when therefore using.
Summary of the invention:
The purpose of this utility model is: a kind of defective that above-mentioned prior art exists that overcomes is provided, make and wear staff and extraneous contamination air insulated, filtration absorption by canister filters out the pernicious gas in the surrounding air, and the anti-biochemical tool comprehensively in the big visual field of clean gas is provided.
The utility model is to realize above-mentioned purpose by following technical solution:
The anti-biochemical tool comprehensively in this big visual field is made of cover body, bag frame, transparent face mask, connection main body, mouth and nose inner cover and headband junction button, and the headband junction button is contained on the bag frame at transparent face mask edge; It is characterized in that: on the outer ring of connection main body a transparent face mask is housed, be fixed with the sealing of cover body two-fold by the bag frame on the transparent face mask edge, inlet valve is equipped with by air-breathing valve seat in the middle part or the both sides that connect main body, outlet valve is housed below the air-breathing valve seat, on the inner of connection main body the mouth and nose inner cover is housed, the inner cover inlet valve is housed on the mouth and nose inner cover, and outlet valve and acoustic diaphragm are equipped with in the middle part that connects main body; The outer end that connects main body is shaped on the connection screw socket, connects on the screw socket by the filter tank seat canister to be housed, and the both sides of transparent face mask respectively are shaped on one and connect screw socket, connect on the screw socket seal cover is housed.By air-breathing valve seat inlet valve is housed in the connection screw socket of transparent face mask both sides, inlet valve is communicated with the air-breathing valve seat that is connected main body, respectively is connected with a canister by the filter tank seat on two connection screw sockets, on the connection screw socket of connection main body outer end seal cover is housed.
The utility model compared with prior art has following beneficial effect:
1. the filter tank seat adopts and to be threaded with being connected screw socket, loads and unloads quick and conveniently, and it is firm to connect.
2. adopt the respiration channel of outlet valve and inlet valve control mask, make inhaled air fully by entering human body behind the canister, gas defence is effective.
3. the contact site of face shield and human body face is by the sealing of silica gel oronasal mask, and good sealing effect makes human body and toxic gas isolated fully.
4. transparent cover has functions such as protecting against shock, interior antifog, outer anti-scraping, and is more safe and reliable when making its work.
5. on the face shield sound-conducting apparatus is housed, when using this face shield to carry out work transmission information, sound is more clear.
6. canister on the face shield or breath device can be made into one or two, and can exchange when making the installation site according to need of work, and canister also can be installed two or only adorn one according to need of work.
