Abstract
The utility model relates to a breather for workers in high-pollution condition, belonging to technical field of working protectors, which is composed of a sealing helm, a sealing cloth, an air tube, and an air pot. The sealing helm is provided with a transparent eye mask, an air inlet, a ventilate hole, and a flexible band, the sealing cloth is integrated with the sealing helm, the upper part of the air pot is provided with an air inlet valve, an adjusting throttle valve, an air-pressure gage, and a safe valve while the bottom is provided with a drainage valve, and two sides are arranged with back belts, and two ends of the air tube are connected with the sealing helm and the air pot. The utility model has low cost, fresh air supply, better sealing, and harmful air insulation, thereby protecting breath organ effectively, to be used in plating condition, dust areas, fire areas and the like, and the utility model can be used to rescue people under wells.
Description
Technical field: the utility model relates to a kind of high pollution air ambient operating personnel respirator, belongs to labour protection apparatus technical field.
Technical background: existing multilayer mouth mask and easy breathing mask generally all can not effectively intercept small dust granules and pernicious gas enters the human body respiration organ; The cost of specialty breathing mask and auxiliary device thereof is also relatively more expensive, is unfavorable for popularizing and uses.With the carbon granules is the filter of sorbing material, can lose adsorption capacity after its carbon granules is saturated, makes harmful dust granules and gas enter the human respiratory tract in a large number, causes the respiratory apparatus damage, even it is lifelong to cause a disease, life threatening.
Summary of the invention: be the high pollution air ambient operating personnel respirator that the safe breathing problem that solves operating personnel under abominable air ambient designs, it is made up of enclosed helmet 1, sealing cloth 2, appendix 3 and gas tank 4.Enclosed helmet 1 is provided with transparent eyeshade 5, air admission hole 6, steam vent 7 and elasticity kicking strap 8, and sealing cloth 2 is structure as a whole with enclosed helmet 1, constitutes protector; Gas tank 4 is provided with intake valve 9, adjustable throttling 10, air gauge 11 and safety valve 12, the bottom is provided with blowoff valve 13, and braces 14 is equipped with in both sides, and appendix 3 is connected between enclosed helmet 1 and the gas tank 4, linking to each other with the two communicates, and constitutes dilution air plant.It is low to the utlity model has cost of manufacture, the capacity fresh air is supplied with, operating personnel's respiratory apparatus and contaminated air environment are strict isolated, dust and pernicious gas can't enter the advantage of human respiratory, be applicable to spray paint, airborne dust operation, poisonous gas leakage are speedily carried out rescue work, the scene of fire is rescued and personnel such as high-risk epidemic victim's medical care use.If after the helmet sealed upgrading, can be used for also that underground work is in danger saves oneself.
Description of drawings:
Accompanying drawing is the utility model schematic diagram.
Among the figure: 1, enclosed helmet, 2, sealing cloth, 3, appendix, 4, gas tank, 5, transparent eyeshade, 6, air admission hole, 7, steam vent, 8, the elasticity kicking strap, 9, intake valve, 10, adjustable throttling, 11, air gauge, 12, safety valve, 13, blowoff valve, 14, braces.
The specific embodiment one:
Below in conjunction with description of drawings embodiment of the present utility model: it is made up of enclosed helmet 1, sealing cloth 2, appendix 3 and gas tank 4.Enclosed helmet 1 and sealing cloth 2 are structure as a whole; One end of appendix 3 is installed on the air admission hole 6 on the enclosed helmet 1, and the other end is installed on the adjustable throttling 10 on gas tank 4 tops; Enclosed helmet 1 is positioned at the transparent eyeshade 5 that eye being provided with is convenient to observe, be positioned at nose and be provided with the air admission hole 6 of supplying with fresh air, be positioned at ear and be provided with the waste gas that to get rid of the human body exhalation, can make the operating personnel hear the steam vent 7 of external voice again, the effect of elasticity kicking strap 8 is that pocket is in the fastening helmet of lower jaw part; Gas tank 4 tops are provided with the intake valve 9 that connects inflatable tool, the adjustable throttling 10 that connects appendix 3, air gauge 11 is used to show the pressure of gas tank compressed air, the effect of safety valve 12 is to rush down pressure when the pressure of gas tank compressed air surpasses setting pressure automatically, and the effect of blowoff valve 13 is that the water and the dirt that amass in the gas tank bottom are drained.Use of the present utility model is in fresh air environment, utilizes inflatable tools such as air pump, gas tank 4 is charged into compressed air to setting pressure, and operating personnel's back gas tank is with enclosed helmet then, connect appendix, open choke valve, just can enter the operation of contaminated air environment.
Because compressed-air actuated pressure forms the directive property air-flow in the exit of air admission hole 6, because the waste gas that human body is breathed out is discrete state, the fresh air that air admission hole 6 discharges can disperse waste gas, can guarantee again to be absorbed by the people smoothly again.Simultaneously, because the stack of compressed air pressure and exhaust gas pressure, make pressure in the enclosed helmet 1 greater than external pressure, the waste gas that human body is breathed out can be successfully from steam vent 7 outflows, and extraneous air can't enter in the helmet.
The specific embodiment two:
The configurable standby gas tank of the utility model several, to prolong time for continuous operation.The also available high voltage bearing soft material air bag of gas tank replaces, to reduce cost.
