Description
Technical field
The utility model relates to a kind of respirator, relates in particular to a kind of breathing mask.
Background technology
Breathing mask is tackled the use chemical warfare agent at first and is grown up in the World War I.At present; Nearly all existing breathing mask all has following common characteristic: be suitable for seal that face is sealed; Thereby a chamber is provided; The sealing part is used to prevent possibly enter in the chamber by contaminated air on every side, and then prevents that contaminated gas from entering in wearer's the lung; Chamber interior at seal is provided with an oronasal mask that is used to seal nose and mouth, and its effect is that the inside and outside differential pressure that lets possible contaminated air can't utilize intake period to cause on every side enters in the face shield through the seal that damages; Seal is provided with the filter that is used to filter contaminated air; These breathing masks all also comprise certain goggles usually, in order to prevent foul atmosphere eyes are caused potential harm.
Yet all there is certain problem in existing breathing mask: at first, this gas mask is at dark, dense smoke or be full of in the environment of poor visibility such as dust, and the user can't recognize the situation of periphery; Secondly, other staff also are not easy to find the user, give escape, rescue, search and brought inconvenience.
Summary of the invention
The goal of the invention of the utility model provides a kind of respiratory protection equipment; This respiratory protection equipment should guarantee that the wearer obtains the reasonable visual field in the environment of poor visibility; And should point out the rescue personnel wearer residing position significantly; Thereby the wearer is come to light in time, to strive for valuable rescue time.
According to the goal of the invention of above-mentioned utility model, the utility model provides a kind of respiratory protection equipment, it comprises: a filter tank and a face shield; Said face shield comprises: a fixed frame, and one is located at the visual window lens on the said fixed frame, and the face shield colloid be located on the said fixed frame; Said in addition respiratory protection equipment also comprises:
One light shows indicating device, and said light shows indicating device and comprises a light-emitting device, a touch-switch and a battery pack that is connected in the series connection circuit, wherein:
Said light-emitting device is fixed on the said fixed frame, and said light-emitting device is set to light and launches to OFP;
Said touch-switch is located on the face shield colloid, and is located on the face of face shield colloid and the applying of people's face.
Light is housed on the described respiratory protection equipment of present technique scheme shows indicating device; The wearer uses this respiratory protection equipment or to be full of in the relatively poor environment of visibility such as dust at dark, dense smoke and obtains the visual field preferably; Thereby under the situation that guarantees eupnea; Make the wearer can be well understood to situation on every side, and then reduce the danger of wearer in adverse circumstances as much as possible, improve wearer's chances of survival.In addition, in the relatively poor environment of visibility, light is set shows indicating device and make that also the wearer also is easy to found by the rescue personnel, in time obtain the probability rescued thereby significantly improve the wearer.
Preferably, in above-mentioned respiratory protection equipment, said light-emitting device is laser lamp or LED lamp.Need to prove that the light-emitting device in the present technique scheme also can be for except laser lamp, other light-emitting devices the LED lamp.
Preferably, in above-mentioned respiratory protection equipment, said fixed frame is the fluorescence fixed frame.It also is to be found by the rescue personnel for the ease of the wearer that fixed frame is set to the fluorescence fixed frame.
The described respiratory protection equipment of the utility model makes it have the following advantages than existing breathing mask owing to adopted technique scheme:
(1) the described respiratory protection equipment of the utility model can make the wearer in the relatively poor environment of visibility, obtain the visual field preferably; Make the wearer can be well understood to situation on every side, thereby reduced the danger of wearer in adverse circumstances to a certain extent;
(2) the described respiratory protection equipment of the utility model can be pointed out the rescue personnel significantly, and the wearer is come to light in time, thereby strives for more rescue time, has improved wearer's chances of survival;
(3) the described respiratory protection equipment of the utility model is simple in structure, easy to use, and production cost is low.

The specific embodiment
Fig. 1, Fig. 2 have shown the described respiratory protection equipment of the utility model structure in the present embodiment.Fig. 3 is the partial enlarged drawing at A place among Fig. 2.Like Fig. 1, Fig. 2 and shown in Figure 3, filter tank 1 is tightly connected with the face shield lower end, and contaminated air around being used for filtering is so that it reaches the breathing requirement.Face shield comprises that a fluorescence fixed frame 4, a visual window lens 2, a face shield colloid 3 and a cover light show indicating device, and wherein light shows indicating device and comprises the laser lamp 5 that is connected in the series circuit, battery 6 and touch-switch 7.Wherein, visual window lens 2 is located at respectively on the fixed frame 4 with face shield colloid 3 hermetically, in order to an airtight chamber to be provided, isolates extraneous contaminated gas, and makes the wearer can observe situation on every side; Laser lamp 5 is fixed on center position on the fluorescence fixed frame 4 through two screws, in order to illuminate the visual field of respiratory protection equipment the place ahead scope; Battery 6 is fixed on the fixed frame 4 through two screws equally, in order to give laser lamp 5 power supplies; Touch-switch 7 is embedded on the face shield colloid 3 of face shield side, in order to the switch of control laser lamp 5.
Please continue to consult Fig. 2, Fig. 3, when respiratory protection equipment was worn on the face, face shield colloid 3 can push with face, and fits tightly, and guaranteed the air-tightness of face shield.The extruding of face shield colloid 3 can make the touch-switch 7 of face shield side contact with fluorescence fixed frame 4, makes touch-switch 7 open, thereby makes laser lamp 5 illuminate field of front vision; When taking off respiratory protection equipment, touch-switch 7 is separated from fluorescence fixed frame 4, makes touch-switch 7 close, thereby laser lamp 5 is extinguished.Like this, laser lamp 5 just need not the manual control switch, just can automatically illuminate field of front vision.
