Description
Technical field:
The utility model relates to a kind of fire-fighting equipment of saving oneself, and particularly relates to a kind of chemistry of fire oxygen self-rescue apparatus.
Technical background:
Fire is harm huge numbers of families' a big disaster, put down in writing according to data, the philtrum of dying in the fire is not to die from big fire itself more than 80%, but be choked to death by dense smoke, at skyscraper, in case the public place breaking out of fire, rescue work is very difficult, the intense stimulus toxic smog that produces in the burning can make the people lose self-control at short notice, so people have just invented a kind of Self-saving breather of chemical oxygen.Self-saving breather of chemical oxygen divides circulating and reciprocating type both at home and abroad.Circulating suction resistance is smaller, and structure is than repetition formula complexity, and cost is higher, mainly wishes when moving because of people to exhale passively, and resistance is smaller for well, pretends the less of life-saving; Reciprocating type simpler slightly than circulating structure, the adopter is more, and the subject matter of existence is that head-shield is not fire-resistant, thermal insulation is little, and air-tightness is bad again when sewing up with heat-insulating cloth, the imitated foreign products of mouth mask body of rubber system, the Chinese's shape of face of not quite coincideing; The air bag poor fire, the inconvenience that profile is long, not attractive in appearance, flat is also not too attractive in appearance; The oxygen generator air inlet does not add airtight stopper, is difficult to guarantee do not make moist in 3 years; Oxygen generating agent is single, and oxygen supply fast must be set up starting device---little oxygen candle etc.; Head-shield, headband are not reflective, are unfavorable for lifesaving and rescuing mutually; Guard time is short, is 15 minutes mostly, and minority is 20 minutes, high-rise life saving and promptly put out a fire, rescue the people and need 30～60 minutes better.
Summary of the invention:
Technical problem to be solved in the utility model provides that a kind of air-tightness is good, oxygen supply is sufficient fast, use and the holding time is long and chemistry of fire oxygen self-rescue apparatus cheap for manufacturing cost.
The technical solution adopted in the utility model is: head-shield adopts flame-proof PVC double faced adhesive tape or synthetic rubber cloth, outer cover approaches aluminium foil cloth or only uses aluminium foil cloth, suture adds airtight, and head adhesive latex or elastic rubber head circle or the airtight circle of Polypropylence Sheet degree of tightness add the fire-retardant degree of tightness of neck; Oxygen generator is established up and down two, and following rubber airtight stopper is placed in the air bag all with the blow vent of rubber airtight stopper, and air bag is provided with down rubber airtight stopper opening device; Air bag is made with special airtight fire-retardant aluminium foil cloth or fire-retardant synthetic rubber, is contained on the head-shield rubber mouth mask.
As improvement of the present utility model, be provided with a reflective tape in the middle of the headband on head-shield, and above head-shield, be provided with a luminous plate sign and a Dumpage type mercoid switch buzzer, both sides, eyeglass top are provided with flash lamp; An oxygen candle is housed in air bag, and air bag is provided with oxygen candle opening device.
As further improvement of the utility model, be provided with a tippet at the neck flame-retardant elastic.
Adopt the chemistry of fire oxygen self-rescue apparatus of technique scheme, head-shield adopts flame-proof PVC double faced adhesive tape or synthetic rubber cloth, outer cover approaches aluminium foil cloth or only uses aluminium foil cloth, suture adds airtight, head adhesive latex or elastic rubber head circle or the airtight circle of Polypropylence Sheet degree of tightness, add the neck flame-retardant elastic, add a tippet at elastic cord, with protection neck and shoulder, be provided with a reflective tape in the middle of the headband on the head-shield, and above head-shield, establish a luminous plate sign and Dumpage type switch buzzer, the bright lamp of sounding is beneficial to missing when the people falls down; Air bag is made with special airtight fire-retardant aluminium foil cloth or fire-retardant synthetic rubber, is contained in head-shield rubber mouth mask top, makes its compactness attractive in appearance again; Oxygen generator is selected two kinds of oxygen generating agents, and a kind of is potassium superoxide; Another kind is on the basis of potassium superoxide, adds catalyst, improves the initial stage of oxygen generating agent and gives birth to oxygen speed; Two blow vents all add the rubber airtight stopper about oxygen generator, be placed on the rubber stopper in the air bag, when urgent the use, must pull out, guaranteed that oxygen generator can not make moist in airtight 3 years, in order to guarantee personal security to greatest extent, prevent to forget when urgent and blow 2～3 implications suddenly, air bag blown stick out, can in air bag, adorn the little oxygen candle of a generating oxygen, under the gastight condition of air bag, draw back the opening device of little oxygen candle when guaranteeing to use, the respirator inner packing adopts vacuum-packed with airtight Polypropylence Sheet, guarantee that medicament can not make moist; So the utility model provides that a kind of air-tightness is good, oxygen supply is sufficient fast, use and the holding time is long and chemistry of fire oxygen self-rescue apparatus cheap for manufacturing cost.
