Abstract

The utility model relates to a chemical oxygen self-rescuer, which is a breathing protecting apparatus whose oxygen generating medicinal cupping is a cylinder, and is equipped with a breathing soft tube and is used for individual escape. A gas distributor is a circular covering body, which is covered on the cylindrical oxygen generating medicinal cupping, the side wall of the circular covering body is equipped with two air pipe ports which are outward extended and are respectively connected with the breathing soft tube and an oxygen candle, and the air pipe ports of the breathing soft tube are capable of being used as one body or a split type with the breathing soft tube. The utility model has the advantages of comfortable wear, safe use and low suction temperature.

Description

Chemical oxygen self-rescuer
Technical field:
The utility model relates to a kind of chemical oxygen self-rescuer, especially relates to the improvement that a kind of chemical pot for generating oxygen is columniform chemical oxygen self-rescuer.
Background technology:
Chemical oxygen self-rescuer is a kind of isolated respiratory protection utensil, has that volume is little, light weight, is not subjected to advantage such as environment for use restriction, and the people wears it and can escape from poisonous and harmful or anoxic environment safely, has therefore obtained using widely under coal mine.The requirement of China's coal-mine safety regulation for operations, at high gas and outstanding mine such as gas, coal is arranged, each personnel of going into the well should carry an isolated self-rescuer.
Its wearing mode of chemical oxygen self-rescuer product of existing cylindrical chemical pot for generating oxygen all is that mouth is held formula in the month, the OXY-BOKS-30 chemical oxygen self-rescuer of producing as German Dreager company.Adopted cylindrical chemical pot for generating oxygen, be connected with gas distributor on the cylindrical medicinal cupping by the heat exchanger of semicircle hard, realized standing and used cylindrical chemical pot for generating oxygen, but the rubber mouth tool sheet of this self-rescuer is fixed on the heat exchanger of semicircle hard, wearing mode is held formula in the month for mouth.Mouth is held the formula wearing mode in the month; rely on fixedly respirator of headband and mouthful place of holding in the month when wearing; reach between tooth and the bite-block stressed bigger between the lips and teeth; particularly when the self-rescuer guard time is long; the increase of the volume and weight of chemical pot for generating oxygen or owing to the wearer runs when causing that respirator rocks; the capital increases stressed between the lips and teeth and between tooth and the bite-block, causes a mouthful tool place gas leakage easily, reduces the security that self-rescuer uses.So it is shorter that mouth is held formula chemical oxygen self-rescuer guard time in the month, because air-breathing path is short, inspiratory airflow can not get sufficient cooling, so suction temperature is also higher, wears uncomfortable simultaneously.
Summary of the invention:
Existing chemical oxygen self-rescuer respiratory resistance is big, suction temperature is high, use is dangerous, wear uncomfortable problem in order to overcome, and the utility model provides a kind of comfortable wearing, safe in utilization, chemical oxygen self-rescuer that suction temperature is low.
Concrete technical scheme is as follows: a kind of chemical oxygen self-rescuer, comprise gas distributor, described gas distributor is the round button lid, be buckled on the cylindrical chemical pot for generating oxygen, the sidewall of round button lid is provided with the outward extending ventilation interface in two places, be connected with breathing hose and oxygen candle respectively, the ventilation interface of breathing hose can with breathing hose as one or split type.
Described gas distributor inboard is provided with the muscle and the cylinder of projection;
Described gas distributor adopts the soft rubber material;
Be placed with the cooling net in the described breathing hose;
Compare with prior art, gas distributor of the present utility model adopts the sidewall at the round button lid to be provided with the outward extending ventilation interface in two places, be connected with the oxygen candle with breathing hose respectively, the ventilation interface of breathing hose can with breathing hose as one or split type, can reach upright the cylindrical chemical pot for generating oxygen that uses, comfortable wearing, safe in utilization, effect that suction temperature is low.

The specific embodiment:
A kind of chemical oxygen self-rescuer comprises a mouthful tool, nose clip, breathing hose, gas distributor, heat insulating mattress, chemical pot for generating oxygen, neck band and waistband, air bag, oxygen candle, shell etc.Described gas distributor is the round button lid, be buckled on the cylindrical chemical pot for generating oxygen, the sidewall of round button lid is provided with the outward extending ventilation interface in two places, is connected with the oxygen candle with breathing hose respectively, and breathing hose ventilation interface can be an one or split type with breathing hose.Described gas distributor inboard is provided with the muscle and the cylinder of projection; The breathing hose ventilation interface of described gas distributor and oxygen candle ventilation interface can be positioned at homonymy, also can be positioned at heteropleural; Described gas distributor adopts the soft rubber material; Be placed with the cooling net in the described breathing hose.
Breathing hose 3 and gas distributor 4 are integral, and breathing hose 3 can be positioned at homonymy with oxygen candle interface 13, as Fig. 2,3; Also can be positioned at heteropleural, as Fig. 4.
Breathing hose 3 and gas distributor 4 are made two bodies, by annulus 17 it is connected as a single entity then, as Fig. 5.Gas distributor interface and oxygen candle interface 13 can be positioned at homonymy, also can be positioned at heteropleural.
Be bonded at the outside of gas distributor 4 as Fig. 1 heat insulating mattress 5, prevent to scald the wearer, with cassette tape 6 gas distributor 4 is fixed on the cylindrical chemical pot for generating oxygen 7, neck band and waistband 8 are enclosed within cylindrical chemical pot for generating oxygen 7 outsides, air bag 10 is fixed on the other end of cylindrical chemical pot for generating oxygen 7 with air bag cassette tape 9, oxygen candle 12 rubber parts by the air bag interface are fixed on the homonymy of breathing hose, and the gas outlet of oxygen candle links to each other with the interface 13 on the gas distributor 4, is placed in the square casing.Inboard (see figure 3) at gas distributor 4 is provided with the muscle 14 of projection and the cylinder 15 of projection, plays steering current and distributes, and prevents that gas distributor 4 is close on the end face of chemical pot for generating oxygen 7, causes the rising of respiratory resistance.
