Abstract
The utility model discloses a head-up display device on an air supply valve of a respirator. The head-up display device comprises the air supply valve. The air supply valve is connected with a full face mask through a full face mask port and an air supply valve insertion port. The bottom of the end, far from the full face mask, of the air supply valve is provided with display device bodies. The bottom of the air supply valve is provided with an end cover which is fixed through screws. The display device bodies are arranged in the end cover. The head-up display device has the advantages that a display region is arranged at the bottom of the air supply valve, the distance between the display region and the eyes of a user is over 160 mm, the sight distance is extended greatly, and visual fatigue of the user is relieved; meanwhile, the user can conveniently know more precise information anytime, operating data are clear, the working efficiency of the user is greatly improved, a fireman can make better decisions, and consequently life security can be guaranteed.
Description
Technical field
The utility model relates to a kind of display unit, particularly the head-up display on a kind of respirator steam supply valve.
Background technology
There is scene, rescue measure and maintenance work in contaminated area, fire that 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 the severe working environment such as 17% 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, by high-voltage tube, is connected with transmitting terminal.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; When storage pressure is when 6MPa is following, 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, its Led position is all near the be connected position of interface of steam supply valve and full facepiece mask, earlier, the distance of Led lamp and eyes the longest also less than 120mm, generally all at 100-110mm; Wireless connections look squarely display end, major part is arranged on full facepiece mask inside, the distance of its Led and eyes is less than 80mm a bit.
The documents patent No. is that 201220007351.1 Chinese patent discloses a kind of air respiratorresuscitator face shield with showing pressure, this pressure-display device is arranged at full facepiece mask upper end, pressure-display device is located in wearer's visual range, although such air respiratorresuscitator face shield has added pressure-display device, reduce user of service and checked manometric frequency, but the wireless connections that he adopts look squarely display end, be arranged at full facepiece mask upper position, its display unit and eye distance are short, it is very painstaking that user seems, and easily produce visual fatigue, affect rescue work, display area shows that the scheme of pressure is too coarse, accurate not simultaneously, pressure directly can not be shown by numeral, and it is very inconvenient to use.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and the head-up display on a kind of novel respirator steam supply valve is provided.
To achieve these goals, the measure that the utility model is taked:
A head-up display on respirator steam supply valve, comprises steam supply valve, on steam supply valve, by full facepiece mask interface and steam supply valve interface, is connected with full facepiece mask, and the bottom position of the described steam supply valve away from full facepiece mask one end is provided with display unit;
Described steam supply valve bottom is an end cap being screwed, and display unit is arranged in end cap.
The beneficial effects of the utility model: viewing area is arranged at the bottom position of steam supply valve, more than having reached 160MM with the distance of eyes, sighting distance is elongated greatly, alleviated user's visual fatigue, user of service can facilitate the more precise information of understanding at any time simultaneously, and operational data is very clear, has greatly improved user of service's operating efficiency, and fireman can be made decision better, to ensure the safety of human life.
Accompanying drawing explanation
Fig. 1, steam supply valve overall structure schematic diagram of the present utility model.
Fig. 2, steam supply valve decomposition texture schematic diagram of the present utility model.
The specific embodiment
A head-up display on respirator steam supply valve, comprises steam supply valve 3, on steam supply valve 3, by full facepiece mask interface 2 and steam supply valve interface 7, is connected with full facepiece mask 1, and the bottom position of the described steam supply valve 3 away from full facepiece mask one end is provided with display unit 6.
Described steam supply valve 3 bottoms be one by the fixing end cap 4 of screw 5, display unit 6 is arranged in end cap 4.
The utility model is installed to the enterprising enforcement of respirator to be used, full facepiece mask 1 is worn on the face, eyes are by shading preventing dust hole, the lens on steam supply valve and the shading preventing dust hole of eyeglass, full facepiece mask, i.e. the information of Observable display unit, and be convenient to intuitively know fast every data message.Display unit 6 is arranged at the bottom position of steam supply valve 3, more than having reached 160MM, has greatly alleviated user's visual fatigue with the distance of eyes, guarantees that user's long periods of wear does not affect one's power of vision.Digital display type is looked squarely to display end is arranged on steam supply valve 3 simultaneously, can directly by numeral, accurately show pressure, display environment temperature, remaining time, the time, and direction on schedule, user can understand directional information at any time like this, even if user also can not got lost, thereby in the situation that not needing to help to see front Digital display intelligent meter with hand, just can accurately understand these information in thick fog environment comprehensively.Greatly improved user of service's operating efficiency, and user of service can be made decision better, to ensure the safety of human life.
Above embodiment, only for the technical solution of the utility model is described in more detail, can not be interpreted as the restriction to the utility model protection domain; Some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection domain of the present utility model.
