Abstract
The utility model discloses a tubular smoke dust prevention shading hole device on a full face mask of a respirator. The tubular smoke dust prevention shading hole device comprises a full face mask body of the respirator. The obverse side of the full face mask body of the respirator is provided with a transparent view window lens. A lens is arranged below the transparent view window lens. The front end of the full face mask body of the respirator is provided with a connector and a connector cover which are connected with an air supply valve of the respirator. The full face mask body of the respirator is provided with two tubular smoke dust prevention shading holes. The full face mask body of the respirator is a spherical face mask or a cylindrical face mask. The two tubular smoke dust prevention shading holes are in bilateral symmetry. When the full face mask body of the respirator is the spherical face mask, the tubular smoke dust prevention shading hole device has the advantages that the closed design is adopted, the weight is light, the working efficiency of users is greatly improved, and a fireman can make better decisions to ensure life security.
Description
Technical field
The utility model relates to a kind of preventing dust shade, particularly the tubulose preventing dust shading aperture apparatus on a kind of respirator full facepiece mask.
Background technology
There is scene, rescue measure and maintenance work in contaminated area, fire that current positive-pressure air respirator can be widely used in other possibility anoxic areas such as fire-fighting, chemical industry, metallurgy, miner, oil.Be designed for user and protect toxic gas, poisonous particle and aerosol, oxygen content lower than 15% the severe working environment such as anaerobic environment, the smog that fire causes, be for fireman or speedily carry out rescue work rescue personnel under the various environment such as dense smoke, poison gas, steam or anoxic, put out a fire safely and effectively, a kind of buoyant apparatus of rescue and relief work and rescue.
At present, positive-pressure air respirator mainly comprises gas cylinder, full facepiece mask, pressure-display device and warning device.Wherein the existing pressure head-up display of positive-pressure air respirator (SCBA) comprises transmitting terminal and looks squarely display end two parts.Transmitting terminal is generally placed in back of the body tool or front, is connected with transmitting terminal by high-voltage tube.Transmitting terminal can be divided into and can be divided into wired and wireless two kinds with the connected mode of looking squarely display end.Look squarely display end and generally all adopt Led display mode, when storage pressure is during at 30-10MPa, Led green light Chang Liang; When storage pressure is during at 10-6MPa, amber light Chang Liang; In the time that storage pressure is below 6MPa, red light is always glittering; That also disposes in addition power supply low-voltage alarm lamp, wireless mode is also provided with paired light.
Wired connection look squarely display end, be generally all arranged on steam supply valve, wireless connections look squarely display end, major part is arranged on full facepiece mask inside.
At present except taper or wedge full facepiece mask, most of respirator full facepiece mask is all less than the shading preventing dust pore structure for head-up display, the impact of receiving ambient light and flue dust when this can cause user of service to observe head-up display, cause not seeing or can't see displaying contents at all, thereby affect user of service's decision-making, also affected rescue work.And taper or the inadequate hommization of its optical characteristics of wedge full facepiece mask, outward appearance is also attractive in appearance not, and weight more reppears approximately 40%, reaches 700 grams, and common face shield is only at 500 grams, and this makes wearer be more prone to tired.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the aperture apparatus of the tubulose preventing dust shading on a kind of respirator full facepiece mask is provided.
To achieve these goals, the measure that the utility model is taked:
Tubulose preventing dust shading aperture apparatus on a kind of respirator full facepiece mask, comprise respirator full facepiece mask body, respirator full facepiece mask body front is provided with transparent window eyeglass, transparent window eyeglass below is provided with eyeglass, respirator full facepiece mask body front end is provided with the interface and the access flap that are connected with respirator steam supply valve, on described respirator full facepiece mask body, is provided with tubulose preventing dust shading hole;
Described respirator full facepiece mask body is spherical face shield or cylindricality face shield;
Described tubulose preventing dust shading hole is symmetrical two;
When described respirator full facepiece mask body is spherical face shield, transparent window eyeglass is hyperbolic configuration;
Described respirator full facepiece mask body is cylindricality face shield, and transparent window eyeglass is simple curve structure, is provided with the excessive portion of handing-over between transparent window eyeglass and eyeglass.
The beneficial effects of the utility model: device adopts closed design, transparent glasses lens from display screen to full facepiece mask has all adopted duct type shading preventing dust device, gear cigarette is dustproof, shading, even and if weak display brightness also can clearly be seen displaying contents clearly, and be not subject to the impact of ambient light power, be conducive to save power supply, and adopt spherical and cylindroid closure assembly, more meet anthroposomatology design, lightweight, greatly improve user of service's operating efficiency, and fireman can be made decision better, to ensure the safety of human life.
