Abstract
The utility model discloses a disinfecting purifying respirator for relief work. The disinfecting purifying respirator for relief work comprises a housing provided with an inner cavity. The front of the housing is provided with an openable door which is provided with an opening. An antigas cartridge is disposed in the housing and is connected with a three-way valve through a gas guide tube. An oxygen cylinder is disposed in the housing is embedded on a fixed ring on the inner wall of the housing. A fixing strap for fixing the oxygen cylinder is disposed on the inner wall of the housing. A gas outlet of the oxygen cylinder is connected with the three-way valve through the gas guide tube. One port of the three-way valve is communicated with a breather disposed on a face mask through the gas guide tube extending out of the opening of the door. The problem that the single filtering way in the prior art provides no second oxygen supply scheme to supply oxygen in emergency and cannot achieve fast timely oxygen supply is solved.
Description
Technical field
The utility model belongs to the appliances for labor protection field, relates in particular to a kind of rescue work sterilizing and purifying respirator.
Background technology
Respirator is the open empty respirator of a kind of self-sufficiency, be widely used in the departments such as fire-fighting, chemical industry, boats and ships, oil, smelting, warehouse, laboratory, mine, under the various environment such as dense smoke, poison gas, steam or anoxic, put out a fire safely and effectively rescue and relief work and rescue for fireman or the rescue personnel that speedily carries out rescue work.These series of products be furnished with afford a wide field of vision, become clear, airtight good full facepiece mask, feeder is furnished with the novel steam supply valve of small volume, lightweight, stable performance; Select the higher high-quality gas cylinder of high strength backboard and safety coefficient; Relief valve unit is equipped with the residual gas alarm, in the storage pressure scope of regulation, can send audible signal to the wearer, reminds the user of service in time to withdraw the scene.
Respirator divides by design principle generally air respiratorresuscitator and oxygen breathing apparatus.
The working time of air respiratorresuscitator is generally 30 ~ 360min, and according to the difference of respirator model, the ceiling value of guard time is different.Generally speaking the guard time of air respiratorresuscitator is slightly shorter than oxygen breathing apparatus.
Air respiratorresuscitator is to put out a fire safely and effectively rescue and relief work and rescue for fireman or the rescue personnel that speedily carries out rescue work under the various environment such as dense smoke, poison gas, steam or anoxic.
Oxygen breathing apparatus claims again isolation type compressed oxygen respirator.Respiratory system is hedged off from the outer world, and instrument and human respiratory form inner loop, provide oxygen by gas cylinder, has that the air bag storage is exhaled, the gas when inhaling.
Existing respirator is the respirator of single a kind of filter type mostly, in oxygen－deficient situation, there is not oxygen system for subsequent use, when accident occurs, time is life, do not have the danger that all may increase trapped personnel a second that prolong more, therefore existing respirator commonly used has influence on carrying out timely smoothly of rescue work sometimes, is unfavorable for as early as possible rescue accidents happened trapped personnel.
The utility model content
The utility model provides a kind of rescue work sterilizing and purifying respirator, and filter type is single in the prior art in case of emergency can have the second cover oxygen supply scheme to carry out oxygen supply in order to solve, and the problem of oxygen can not be provided quickly.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of rescue work sterilizing and purifying respirator, comprise crust of the device, and form a cavity in the shell, the front side of shell is openable door, is provided with opening at door;
Be provided with canister in the shell, canister is connected with three-way valve by wireway;
Be provided with oxygen cylinder in the shell, oxygen cylinder is embedded on the clamping rings on the shell madial wall, is provided with fixed band fixed oxygen gas cylinder on the shell madial wall, and the gas outlet of oxygen cylinder is connected with three-way valve by wireway;
One of them port of three-way valve stretches out the opening that is arranged on the door and communicates with respirator on being arranged on face shield by wireway.
Described clamping rings adopts hard metal material to prepare.
The shape of described opening can be rectangle, annular, circle, triangle.
Described face shield is whole to adopt transparent hard plastics to prepare, and adopts flexible rubber to prepare in the edge of face shield part.
Described fixed band is again with adhesive tape or rubber strip.
Described three-way valve adopts the engineering plastics preparation of environmental protection.
Compared with prior art, a kind of rescue work of the utility model is with the beneficial effect of sterilizing and purifying respirator: be provided with canister and oxygen cylinder in the shell, when carrying out rescue work when having an accident escape or after the accident generation, can preferentially adopt the oxygen in the oxygen cylinder, because the oxygen in the oxygen cylinder is definitely nontoxic, can not work the mischief to human body, after oxygen in oxygen cylinder is finished, the user does not still flee from out from the scene of the accident or rescue work when being deployed into critical juncture smoothly, three-way valve can be closed with the switch between the oxygen cylinder so, the employing canister purifies air, provide safer oxygen, even the help user gets rid of poverty smoothly or just goes out trapped personnel.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, be described in detail as follows.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-shell, 2-canister, 3-oxygen cylinder, 4-three-way valve, 5-fixed band, 6-respirator, 7-opening, 8-wireway, 9-face shield, 10-clamping rings.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of rescue work sterilizing and purifying respirator comprises crust of the device 1, cavity of shell 1 interior formation, and the front side of shell 1 is openable door, is provided with opening 7 at door;
Be provided with canister 2 in the shell 1, canister 2 is connected with three-way valve 4 by wireway 8;
Be provided with oxygen cylinder 3 in the shell 1, oxygen cylinder 3 is embedded on the clamping rings 10 on shell 1 madial wall, is provided with fixed band 5 fixed oxygen gas cylinders 3 on shell 1 madial wall, and the gas outlet of oxygen cylinder 3 is connected with three-way valve 4 by wireway 8;
