A kind of emergency light with air draft mechanism
Technical field
The present invention relates to emergency light field, more particularly to a kind of emergency light with air draft mechanism.
Background technology
Existing emergency light carries smoke inductor, but smog can not be extracted so that can not in fire
The preferably life security of protection people, it is impossible to meet the use demand of people.
So existing emergency light needs further to improve.
The content of the invention
The invention aims to overcome weak point of the prior art, there is provided a kind of emergent photograph with air draft mechanism
Bright lamp.
In order to achieve the above object, the present invention uses following scheme:
A kind of emergency light with air draft mechanism, includes installation housing, is provided with described installation housing forward end
Indicator lamp, illuminating lamp plate is provided with described installation housing upper end, smoke sensing is provided with described installation housing lower end
Device, it is characterised in that:The air draft mechanism that can be evacuated to smog is provided with described mounting shell body, in described mounting shell
Body rear end, which is provided with, can drive air draft mechanism to stretch out the external drive mechanism of mounting shell.
Heretofore described a kind of emergency light with air draft mechanism, it is characterised in that described air draft mechanism includes
The housing being symmetricly set in mounting shell body, motor is provided with described housing, fan is provided with described motor, in institute
The housing bottom surface stated is provided with ventilating opening, and vent hose is connected with described ventilating opening.
Heretofore described a kind of emergency light with air draft mechanism, it is characterised in that described drive mechanism includes
The rack being arranged on housing rear end face, the second motor is provided with described installation housing, in the second described motor
Axle is provided with gear, and described gear and rack are ratcheting mutually.
Heretofore described a kind of emergency light with air draft mechanism, it is characterised in that set on described installation housing
There is inserting groove, guide rod is provided with described housing, described guide rod is arranged in inserting groove.
Heretofore described a kind of emergency light with air draft mechanism, it is characterised in that described fan is turbine wind
Fan.
In summary, the present invention is relative to prior art its advantage:
The present invention is simple in construction, easy to use, senses smog by smoke inductor and is driven so as to start drive mechanism
Air draft mechanism moves outward, then starts air draft mechanism and carries out exhausting to air, simple in construction so as to which smog is extracted out, practical
Property is strong.

Embodiment
The invention will be further described with embodiment for explanation below in conjunction with the accompanying drawings:
A kind of emergency light with air draft mechanism as shown in Figures 1 to 4, include installation housing 1, in described installation
The front end of housing 1 is provided with indicator lamp 2, illuminating lamp plate 4 is provided with the described upper end of installation housing 1, in described installation housing 1
Lower end is provided with smoke inductor 3, the air draft mechanism 5 that can be evacuated to smog is provided with described installation housing 1, in institute
Installation housing 1 rear end stated is provided with the drive mechanism 6 that air draft mechanism 5 can be driven to stretch out outside installation housing 1, passes through smoke sensing
Device senses smog and drives air draft mechanism to move outward so as to start drive mechanism, then starts air draft mechanism and air is taken out
Wind, it is simple in construction so as to which smog is extracted out, it is practical.
Heretofore described air draft mechanism 5 includes the housing 51 being symmetricly set in installation housing 1, in described housing
Motor 52 is provided with 51, fan 53 is provided with described motor 52, ventilating opening 54 is provided with the described bottom surface of housing 51,
Vent hose 55 is connected with described ventilating opening 54, is rotated by motor driven fan, so as to exhausting, then passes through ventilating opening
Discharged by vent hose, it is simple in construction, it is practical.
Heretofore described drive mechanism 6 includes the rack 62 being arranged on the rear end face of housing 51, in described installation
Housing 1 is provided with the second motor 61, and gear 63, described gear 63 and rack are provided with the described motor shaft of the second motor 61
62 is ratcheting mutually, is rotated by the second motor driven gear, gear and rack-driving so that housing moves, simple in construction, practical
Property is strong.
Heretofore described installation housing 1 is provided with inserting groove 65, and guide rod 64, institute are provided with described housing 51
The guide rod 64 stated is arranged in inserting groove 65, simple in construction, practical.
Heretofore described fan 53 is turbofan, simple in construction, practical.
