Abstract
The utility model relates to a smog alarm labyrinth for inducing smog and sensing alarm before the fire happens, comprising a maze, an emitter-receiver tube, a dark slide and an upper cover and a lower cover of the labyrinth. The circle wall of the upper cover or the lower cover of the labyrinth is equipped with a labyrinth unit curved distributed in a V shape, and the inner length of edge of each V-shaped curved labyrinth unit is shorter than the outer length of edge, namely S1 < S2. The inner wall of the maze is in a sharp corner shape and the sharp corner faces the inner side. Wherein the labyrinth unit curved distributed in a V-shape extends the infrared ray scattering absorption surface, and the curved portion is convenient for smog to come into and go out of the labyrinth smoothly, which causes the scattering of the emitter tube and the receiver tube to reach to optimum. Also the curved portion turns back all the rays including the infrared ray outside the labyrinth to come into the labyrinth, only allows the smog to come into the labyrinth, prevents the outer rays from disturbing the receiver tube to receive the smog signals and avoids the misinformation created by the oversized reflection of the infrared ray on the labyrinth surface, thereby solving the problem of the oversized reflection of the infrared ray on the labyrinth surface.
Description
Technical field
The utility model relates to a kind of light that prevents and enters the photoelectricity labyrinth nernst cell spacer assembly of smoke alarm, and specifically the utility model relates to a kind of and allows smog to enter the device that smog alarm is carried out in the optoelectronic induction chamber.Its labyrinth is a mechanism that is used for induction smog sensor alarming before fire is arranged.
Background technology
At present, known smog alarm labyrinth structure is normally cooperated by labyrinth, transmit-receive tube, shadow shield and labyrinth upper and lower covers and forms.Its principle is after smog enters the labyrinth, blocks all light that comprise Infrared outside the labyrinth by labyrinth and enters in the labyrinth.This labyrinth only allows smog to enter the labyrinth, prevents that extraneous light from disturbing receiving tube to receive smoke signal.Infrared receiving tube receive only by power valve send through the smog light reflected, infrared receiving tube receives the Infrared of being sent by power valve through smog reflection and obtains alerting signal and report to the police.Because the different smog alarm labyrinth of prior art structure, because of the excessive defective of its labyrinth surface reflection Infrared, cause often wrong report or its receiving tube do not receive the labyrinth wall the surface red UV light reflection and do not reported to the police in the smog alarm labyrinth.
Summary of the invention
There is weak point in order to overcome above-mentioned prior art smog alarm labyrinth, provide a kind of and can not only make the smooth and easy turnover of smog labyrinth, and can increase Infrared scattering absorption surface, prevent that all light enters the smoke alarm labyrinth that wrong report is caused in the labyrinth outside the excessive and labyrinth of labyrinth surface reflection Infrared.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of smoke alarm labyrinth of forming that cooperated by labyrinth, transmit-receive tube, shadow shield and labyrinth upper and lower covers, it is characterized in that described labyrinth loam cake or lower cover circumferential inner wall are shaped on the unit, labyrinth that is " ㄑ " word shape bend alignment, and short foreign minister in the length of side of unit, the crooked labyrinth of each " ㄑ " word shape, be S1＜S2, the inboard, labyrinth is angular shape, and wedge angle to the inside simultaneously.
Described transmit-receive tube (being power valve and receiving tube) is installed in the surface of labyrinth wall and distributes by 120 ° of branches such as circumference, and its unthreaded hole gap length degree is 2 ± 1mm.
The utility model has following beneficial effect than prior art.
Be the unit, interior short foreign minister labyrinth of " ㄑ " word shape bend alignment, increased Infrared scattering absorption surface; The angle of bend has made things convenient for the smooth and easy turnover of smog labyrinth.The labyrinth unit that wedge angle is angular shape to the inside can make power valve and receiving tube scattering reach best.Having blocked all light that comprise Infrared outside the labyrinth by the labyrinth that is " ㄑ " word shape bend alignment enters in the labyrinth, make its permission smog enter the labyrinth, infrared receiving tube receives only the light after the smog reflection that is sent by power valve, has played to prevent that extraneous light from disturbing receiving tube to receive smoke signal and the excessive wrong report that causes of labyrinth surface reflection Infrared.Angle is the power valve of θ=120 ° distribution and the infrared light rays of receiving tube, makes the Infrared of smog reflection that good angle be arranged.Unthreaded hole gap length degree is 2 ± 1mm, and scattering angle is that the infrared transmitting tube of Φ=20 ± 1 ° can reduce too much Infrared produce reflection in the labyrinth, has solved that the surface reflection Infrared is excessive to cause wrong report.
Description of drawings
In order to further specify rather than limit above-mentioned implementation of the present utility model, below in conjunction with drawings and Examples the utility model is further specified, but therefore the utility model is not limited among the described practical range.All these designs should be considered as disclosed content of present technique and protection domain of the present utility model.
