Description
Technical field
A kind of fire-fighting equipment is the utility model is related to, especially a kind of malicious type fire-fighting head-shield of filter.
Background technology
Substantial amounts of toxic gas can be produced for various reasons in scene of fire, many cases prove, human body is inhaled in fire
Enter excessive toxic gas or dense smoke is more fatal than flame combustion.Present fire mask or head-shield are often by flameproof fabric
Material is made, and only sets simple air filter, and air filter is generally made of active carbon filter material.Such structure can be effective
The suction of dense smoke is reduced, but method does not remove the toxic gases such as carbon monoxide, protection effect is bad.
In addition existing fire-fighting head-shield design is also unreasonable, is in emergency circumstances used in fire disaster escaping etc., under extreme case
Occur and filtration apparatus is thrown away into head-shield, the various problems such as dust accumulation are not used in head-shield, endanger the life security of user！
The content of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of fire-fighting head-shield for effectively improving security performance.
The technical solution of the utility model is：
The malicious type fire-fighting head-shield of one kind filter, it is characterised in that：It include cover body, oronasal mask, canister, goggles, the lantern ring and
Outlet valve, the cover body are a fire-proof fabric head-shield for coordinating human body head to set, and oronasal mask is equipped with the cover body, described
Oronasal mask front end is equipped with canister, and the canister periphery is provided with a concave ring, and the canister rear end insertion oronasal mask is anterior,
Venting channels in the oronasal mask are connected with the rear end venthole of canister, and the lantern ring is anterior by cover body front portion, oronasal mask
The concave ring periphery of canister is tightly held in, the cover body coordinates human body eye to be equipped with goggles, and the cover body coordinates human body
Neck is equipped with elastic cover, and the lower part of cover body is only fitted in user's neck after head is stretched into cover body easy to user, prevents dense smoke
Enter head-shield with poison gas；The cover body side is at least provided with an outlet valve, its act on be so that head-shield using canister as into
Gas port, outlet valve are gas outlet, ensure the exhaust gas of characteristics of contaminated respiratory droplets and can smoothly discharge and toxic gas will not be introduced head-shield.
Further, the cover body rear portion is provided with trousers loop, and the lantern ring both sides connect same root telescopic band, described flexible
Band passes through trousers loop, since cover body is that fabric is formed, is needed after wearing in order to preferably fix oronasal mask and canister using flexible
Band ties the lantern ring using the human body back side of head as impetus tight.
Further, the front end venthole of the canister has filled in the first rubber stopper, and rear end venthole has filled in second
Rubber stopper, two rubber stoppers are connected using rope, its effect is easy for assembling, and in addition can effectively prevent head-shield product in storage
Dirt.
Further, the lantern ring is metal material.
Further, the goggles is fire retardant plastic material, and material is soft, its effect is to prevent the glass in way of escaping
Press against eyes or skin.
The beneficial effects of the utility model are：The utility model, can be by oxidizing ferment by an oxygen by setting canister
Change the toxic gases such as carbon and be oxidized to carbon dioxide, avoid user from being poisoned；It is by the lantern ring that oronasal mask, cover body and canister is close
It is connected, wearing is effectively combined with head additionally by telescopic band, safe and reliable during escape, canister is equipped with rubber stopper,
With good dust-proof effect.
