Abstract

The invention belongs to fire self-rescue escape fire equipment, and relates to a portable fire self-rescuer. The portable fire self-rescuer is manly composed of a mask, a compressible gas bag, an adsorbent box and a gas guide hose. The cross section of the compressible gas bag is in a corrugated sawtooth shape, and gas exhaust and suction can be achieved through manual compression and stretching; and one-way opening blocking sheets are arranged at the gas inlet end and the gas outlet end of the compressible gas bag correspondingly, and therefore gas is prevented from flowing back. The gas outlet end of the compressible gas bag is connected with the mask through the gas guide hose, and the gas inlet end of the compressible gas bag is in threaded connection with the adsorbent box. The adsorbent box can store a smoke filter agent and activated carbon and is used for filtering poisonous gas. The other end of the adsorbent box is connected with the gas guide hose, and the gas guide hose can droop to the position close to the ground or stretch out of a window when necessary. The portable fire self-rescuer has the beneficial effects of being simple in structure, small in size, low in weight and low in cost and can be compressed and folded to be stored in a packaging bag for standby application in a home or a public place. When a fire accident happens, personnel can inhale fresh air close to the ground or outdoor fresh air by means of the portable fire self-rescuer, self-rescue escape time is won, and casualties of the personnel in fires are reduced.

Description

A kind of portable fire self-rescuer

Technical field:

The present invention relates to a kind of portable fire self-rescuer, belong to technical field of fire control.

Background technology:

In all kinds of natural disasters, fire is the disaster that occurrence frequency is the highest.Cause casualties in a fire is main Reason is the toxic gas in smog.Statistical result shows to cause the ratio of death to be significantly larger than in fire because sucking toxic gas Other injures the death caused.According to statistics, in fire, the died of more than 85% is caused by the impact of smog, the biggest portion Point suck toxic gas stupor in flue dust and lethal.During due to breaking out of fire, flue gas is gathered in upper space mostly, tool Have creep up fast, laterally spread slow feature, therefore, correct fire disaster escaping mode is not to cover mouth and nose with wet towel, not Walk upright, should bend over or creep.But, when a fire, scene of fire the most in public places, due to probably Unbearably, being eager to flee from, people cannot find wet towel in time, bends over or creeps more difficult, causing personnel the most crowded, drag Having prolonged time departure, trapped personnel has sucked toxic gas, the main cause that this situation causes casualties often.

Summary of the invention:

The fire gas mask volume that existing market is sold is relatively big, and structure is complicated, and cost is high.At fire burst scene, escape Survivor is difficult to obtain this type of gas mask in time and saves oneself and flee from the scene of a fire.This patent provides a kind of portable fire self-help apparatus, can Using as family, public place Daily Level Readiness product, in order to Emergency use when fire occurs.

The technical solution adopted for the present invention to solve the technical problems is: portable fire self-help apparatus is mainly by high temperature resistant The face shield that environment-friendly materials are made, compressible air bag, adsorbent box, soft air-guide pipe form.The horizontal section of compressible air bag is fold Zigzag, manually can realize aerofluxus and air-breathing by compression and tension, and be respectively equipped with list at air bag air inlet and outlet port To opening catch, prevent gas backflow.The outlet port of compressible air bag is connected with face shield by soft air-guide pipe, its inlet port With adsorbent box thread connection.Adsorbent box can store filter fumicants and activated carbon, for filtering poisonous institute body.Medicine in adsorbent box Agent can regularly replace.The adsorbent box other end is connected with soft air-guide pipe, and soft air-guide pipe can hang down to place near the ground or stretch when necessary Exit window is outdoor.

The invention has the beneficial effects as follows this portable fire self-rescuer simple in construction, cheap, volume is little, lightweight, Being used as fire disaster emergency can be in family, public place to compress rugosity off-duty storage.When fire surprisingly occurs, use This device personnel withdraw without crawling, and can suck near the ground or outdoor fresh air, strive for saving oneself when fleeing from during escape Between, reduce personnel's injures and deaths in a fire.

Accompanying drawing illustrates:

Fig. 1 portable fire self-rescuer is always schemed.

Fig. 2 face shield view；

Fig. 3 compressible air bag view.

In figure: 1, face shield, 2, compressible air bag, 3, adsorbent box, 4, soft air-guide pipe, 5, mask fixing band ear, 6, face shield Steam vent, 7, the unidirectional unlatching in air bag gas outlet catch, 8, air bag gas outlet, 9, air bag air inlet, 10, air bag air inlet is unidirectional opens Open catch.

Detailed description of the invention:

Portable fire self-rescuer is mainly made up of face shield 1, compressible air bag 2, adsorbent box 3, soft air-guide pipe 4.Can press Contracting air bag 2 side is fold zigzag, manually can realize aerofluxus and air-breathing by compression and tension.Air bag gas outlet 8 and air bag Air inlet 9 is respectively equipped with the unidirectional unlatching in air bag gas outlet catch 7 and air bag air inlet unidirectional unlatching catch 10, prevents gas from falling Stream.

The outlet port of compressible air bag 2 is connected with face shield 1 by soft air-guide pipe 4, its inlet port and adsorbent box 3 spiral shell Stricture of vagina couples.Filter fumicants and activated carbon can be stored, for filtering poisonous institute body in adsorbent box 3.Adsorbent box 3 is detachable, it is achieved Filtration medicament regularly replaces.The other end of adsorbent box 3 is connected with soft air-guide pipe 4.Soft air-guide pipe 4 can fall to place near the ground or Stretch out if desired outside window.

Face shield 1, with mask fixing band ear 5, is fixed on face by stable for face shield 1 during use closely.Characteristics of contaminated respiratory droplets gas Discharged by face shield air vent 6.

This portable fire self-rescuer is cheap, can compress stored collapsed.Under normal circumstances, formula fire hazard self-rescuer is taken Compressible folds flat is in packaging bag.It is little that this self-help apparatus has volume, lightweight, can facilitate and to be packed by band with adhesive tape Self-rescuer sticks in family or in public place, under the seats such as hotel, dining room, cinema, in order to meets an urgent need and is used.

When there is unexpected fire, this portable fire self-help apparatus that trapped personnel can will be placed in packaging bag easily Take out, tear outer packaging bag, put on face shield 1, fasten mask fixing band ear 5, can use.Use this device, it is not necessary to crawl to remove From thus cause more serious personnel crowded with trample.Personnel can flee from rapidly by an edge escape way, extruding and Stretch compressible air bag 2.Forming low pressure when compressible air bag 2 stretches in air bag, the gas of ground proximity is inhaled by soft air-guide pipe 4 Enter.The gas sucked flows into compressible air bag 2 after filtering out toxic gas through the medicament in adsorbent box 3, and in air bag pressure Breathe for people in soft air-guide pipe 4 flows to face shield 1 region during contracting, and the gas of people's exhalation is discharged by the air vent 6 on face shield.

Can not flee from time if scene is crowded, trapped personnel also can temporarily find neighbouring window, is stretched by soft air-guide pipe 4 To open air, suck fresh air, wait that professional's rescue is fled from.

Last it is noted that the preferable enforcement of the explanation more than present invention and accompanying drawing, the only present invention, the most right The restriction of embodiment.For those of ordinary skill in the field, can also be made it on the basis of the above description The change of its multi-form or variation.And the obvious change thus amplified out or variation still fall within the guarantor of the present invention Protect among scope.
