Description
The utility model relates to a kind of security against fire apparatus, specifically is a kind of portable type fire Smoke prevention headgear of choking.
When taking place, fire produces a large amount of smog and toxic gas; in order to protect the individual when running into fire; can eupnea; all researching and producing various fire disaster escaping masks both at home and abroad; its product mainly contains filtering type and isolated two types; filtering type is the breathing of the air that smog and poison gas are contained in the scene of a fire being filtered the guarantor, and getting the filtering type fire disaster escaping headgear that Lego Corp produces as Germany is to filter the cigarette cover with ultra-fine fibre glass, uses M

UO makes to transform the catalyst of carbon monoxide, and other micro-inorganic poison gas is also had filtration, weight 1KG, volume 190 * 135 * 80(MM), this product only are applicable to be deposited standbyly, carries just very difficult, can not often carry, isolated product is to make oxygen generating agent with potassium superoxide, also is not subjected to the restriction of ambient atmos, smog under dangerous environment, and service condition is extensive, the about 1KG of weight, volume is bigger, and its weak point is to deposit standbyly, can not carry.Though portable Smoke prevention headgear is arranged, flame retardant plastics headgear as the Japan's production eighties, it has given prominence to the simple characteristics that can carry, but in the excuse cover is a big respiration dead space, can cause gathering of giving off carbon dioxide, can reach 4%, oxygen concentration can be reduced to below 15%, and this structure self can cause people's life harm.
The purpose of this utility model provides a kind of simple and reasonable for structure, and is safe and reliable, the portable fire Smoke prevention easy to carry headgear of choking.
Structure of the present utility model comprises headgear main body (4), filter (3), one-way breather valve (2), flexible afflux cover (6), elastic cowling clip (5), filter (3) places the rear portion or the both sides of headgear, the flexible afflux cover of being made up of volute spring (6) places the snout of headgear (4), one-way breather valve is contained in the front end of flexible afflux cover (6), the air inlet and the formation isolating construction of exhaling, the eye of headgear (4) has film eye window (1), and elastic cowling clip (5) is fixed on the neck of headgear (4).
The utility model has the advantages that simple and reasonable, Smoke prevention i.e. to external world smog, the poison gas filtration of headgear of choking, again the carbon dioxide of self breathing out is separated with oxygen (air) in the cover, the interior air of headgear is fully taken a breath, head is comfortable, not vexed, steam is few, safe and reliable in the headgear, the afflux cover is that spring structure is foldable, heavily about 90G, volume is little, is easy to carry, easy to use, it is more reliable than the sealing of demifacet cover to tighten sealing with the thin headgear material of neck neck, also can be connected with externally connected portable formula oxygen supply, make under anaerobic conditions can the guarantor safety.
Below in conjunction with drawings and Examples structure of the present utility model is further described.
Fig. 1 is the utility model structure embodiment 1 front view.
Fig. 2 is the utility model structure embodiment 1 side view.
Fig. 3 is the utility model structure embodiment 2 front views.
Fig. 4 is that the utility model structure embodiment 3 bands are exhaled, the afflux cover structure schematic diagram of intake valve.
Fig. 5 is that the utility model structure embodiment 3 bands are exhaled, the afflux cover structure vertical view of intake valve.
By accompanying drawing as can be known, its structure comprises headgear main body (4), filter (3), one-way breather valve (2), flexible afflux cover (6), elastic cowling clip (5), filter (3) places the rear portion or two of headgear, the flexible afflux cover (6) that side is made up of volute spring places the snout of headgear (4), one-way breather valve is contained in the front end of flexible afflux cover (6), the air inlet and the formation isolating construction of exhaling, the eye of headgear (4) has film eye window (1), elastic cowling clip (5) is fixed on the neck of headgear (4), filter (3) is contained in rear portion or the side and flexible afflux cover (6) the formation separated structures of headgear, carbon dioxide in the expiration is subjected to the control of afflux cover and one-way breather valve, form unidirectional straight-flow air, no longer be diffused in the headgear, reduced concentration of carbon dioxide in the headgear dead space.Because large tracts of land enters the extraneous air through purifying from people's back of head or side, towards rare foul atmosphere in the headgear, exhale and discharge through afflux cover demifacet again, the interior oxygen concentration of headgear is remained between the 19-21%, solved the interior oxygen concentration of conventional headgear and be lower than 18% problem.
Among accompanying drawing 3 embodiment, be provided with an intake valve (11) in the headgear bottom, can be connected oxygen supply (13) with portable oxygen supply, other parts are identical with example structure.Oxygen is still sufficient in the just general atmosphere of fire, only can escape with headgear, if the time slightly length anaerobic condition will take place, if feel anoxic in the escape process, can utilize portable oxygen supply (13), by air inlet pipe (11) oxygen supply in headgear, the outlet of chlorate oxygen supply (13) links to each other with air inlet pipe (11) through tube connector (12), oxygen supply (13) is contained in chest and hangs in the bag (14), draws back the draw ring on the oxygen supply (13), transfers to pin, the oxygen phase takes place in oxygen supply immediately, oxygen concentration is more than 21% in the headgear, and with guarantor's eupnea, chest is hung in the bag and is provided with small flashlight bag (15).
Among accompanying drawing (4), (5) embodiment, its structure is identical with aforementioned structure, just is provided with one-way breather valve (2) in the front portion of flexible afflux cover (6), is provided with one-way sucting valve (6 ') in the side.
Filter of the present utility model (3) is made up of fire-retardant carbon fiber, noble metal (platinum-palladium or manganese-copper) catalysis Ji layer, polypropylene fibre particulate filter, can filter toxic gas, inorganic poison gas, carbon monoxide and smog, for guaranteeing concentration of oxygen in the headgear, filter (33) is provided with film reverse resistance blade, blade is made with soft material, cut many half-open holes in its surface, the part of incision plays reverse valve action, to suppress in the headgear oxygen to external diffusion.Headgear is made or is made with fire-retardant heatproof plastic sheeting with the textile cloth composite aluminium film through flame treatment.Eye window (1) is made with the polytetrafluoroethylene (PTFE) transparent membrane, and heat resistance is good, can fold arbitrarily, and when wearing such as inside hazes, and rubbing can recover transparent immediately outside.
