Description
Technical field
The utility model relates to a kind of breathing apparatus, is specially a kind of voice rescue face shield.
Background technology
At present, when the rescue team member is in rescue and relief work under scene of fire or the mine,, avoid sucking flue gas or toxic gas, must wear face shield and carry out necessary protection for rescue personnel's personal safety.Traditional face shield enters face shield in order to prevent toxic gas, so seal tighter, the drawback of bringing simultaneously is exactly to be difficult to send loud and clear sound to OFP, propaganda directed to communicate for the rescue team member makes troubles in cooperation dialogue mutually or when seeking the on-the-spot distress personnel in disaster area, for example the fire fighter will be with face shield to seek the scene of a fire masses in danger in smog, have on the tight face shield of sealing and can't send loud and clear sound searching person in distress, for example under the coal mine gas explosion takes place again, the rescue team member will wear oxygen cylinder and the gas mask that complements one another to downhole rescuing, wears the gas mask that seals just is difficult to send loud and clear sound searching person in distress under subsurface environment orientation.Usually the rescue team member need wear a transmitter that separates with face shield and radio station in addition, during use, the radio station is tied up between waist, needing to rescue team member's hand microphone simultaneously shouts near face shield, use inconvenience, and in that the situation is tense, the rescue site of circumstance complication, the circuit between radio station and the transmitter very easily is hooked on the on-the-spot foreign matter, sues and labours for the rescue team member and affects.
Summary of the invention
There is unreasonable structure in the utility model, uses problems such as inconvenience, complex operation in order to solve existing rescue face shield, and a kind of language rescue face shield is provided.
The utility model is to adopt following technical scheme to realize: voice rescue face shield, comprise mask body and be arranged on air inlet, exhalation vents on the mask body, innovative point of the present utility model is in the mask body and the position that is positioned at air inlet and exhalation vents is packaged with the speech amplifier that comprises power supply, voice magnification circuit plate, and mask body is provided with the power switch of speech amplifier.The utility model is built in speech amplifier in the face shield, not only seals tight but also can send loud and clear voice to the external world, and the rescue team member only need stir the power switch that is positioned on the mask body and can operate.
Described mask body is provided with audio conversion switch, audio frequency accessory power outlet and the power source charges input socket that is connected with the voice magnification circuit plate, its sound intermediate frequency accessory power outlet and power source charges input socket are made one, above-mentioned audio conversion switch can be converted to voice signal the phone output audio signal, can on the audio frequency accessory power outlet, connect telephone as required then, when the rescue team member sues and labours under mine, also can get in touch with the external world; Described power source charges input socket can in time charge to power supply.
Power supply and voice magnification circuit plate outer filling epoxy sealing layer in the described speech amplifier can prevent spark, satisfy requirement of explosion proof.
Compared with prior art, face shield described in the utility model had not only sealed tight but also can send loud and clear voice to the external world, and was simple in structure, easy to use, cost of manufacture is low, has effectively improved the serviceability of rescue face shield.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-mask body; The 2-air inlet; The 3-exhalation vents; The 4-speech amplifier; The 5-power switch; 6-audio conversion switch; 7-audio frequency accessory power outlet; 8-power source charges input socket; The 9-headband.
The specific embodiment
Voice rescue face shield, as shown in Figure 1, the air inlet 2, the exhalation vents 3 that comprise mask body 1, headband 9 and be opened on the mask body 1, in the mask body 1 and position that is positioned at air inlet and exhalation vents is packaged with the speech amplifier 4 that comprises power supply, voice magnification circuit plate, the power switch 5 of speech amplifier is housed on the mask body 1, the structure of this speech amplifier and operation principle are that the ordinary skill of this area is known, described power supply adopts ferric phosphate lithium cell, life-span is long, capacity is big, volume is little, can charge repeatedly 5000 times; The audio conversion switch 6, audio frequency accessory power outlet 7 and the power source charges input socket 8 that are connected with the voice magnification circuit plate are housed on the mask body 1, its sound intermediate frequency accessory power outlet 7 and power source charges input socket 8 are made one, this socket can adopt the aviation socket, connects reliable; Power supply and voice magnification circuit plate outer filling epoxy sealing layer in the speech amplifier 4.
During use, according to the wearing mode of traditional face shield face shield being rescued in voice is worn on the head, when rescue site need be opened use, the power switch of opening on the mask body gets final product, when using phone to converse if desired, open the audio conversion switch, the line socket of phone is inserted the audio frequency accessory power outlet get final product.
