Embodiment
Below in conjunction with embodiment, embodiment of the present utility model is described.
As illustrated in fig. 1 and 2, be respectively sectional view and the inner structure schematic diagram of independent cigarette sense detecting alarm of the present utility model.Independent cigarette sense detecting alarm of the present utility model comprises: outer cover 8, mounting seat 16, drain pan 10, circuit board 11, labyrinth, cigarette sense probe unit, audible alarm unit and battery case 12.Wherein, outer cover 8 is arranged on the top of drain pan 10.Drain pan 10 is arranged on the top of mounting seat 16.Mounting seat 16 generally is contained on the roof, room that needs monitoring, side wall.In the utility model one preferred embodiment, outer cover 8, mounting seat 16 and drain pan 10 are circle.The gap that forms between outer cover 8 and drain pan 10 is as fume inlet passage 9.Even the labyrinth is not the center that is positioned at independent cigarette sense detecting alarm, the design of this fume inlet passage 9 can realize that also independent cigarette sense detecting alarm feels cigarette in all directions delicately.Also be provided with on the inside surface of outer cover 8 and lead the cigarette partition wall, also can make each orientation, labyrinth advance cigarette even.Circuit board 11 is arranged on the upside of drain pan 10.Circuit board 11 comprises micro-chip processor.Battery case 12 is arranged on the downside of drain pan 10, and and circuit board 11 electrical connections.Battery is installed the side that warning bar 17 is arranged on battery case 12.After the battery of packing into, battery is installed warning bar 17 with battery and is pressed in battery case 12; At this moment, the drain pan 10 of independent cigarette sense detecting alarm just can connect with mounting seat 16.When battery not being installed in battery case 12, battery is installed warning bar 17 and is protruded from outside battery case 12.As shown in Figure 3 and Figure 4, be respectively the sectional view in labyrinth of independent cigarette sense detecting alarm of the present utility model and the vertical view of labyrinth lid.The labyrinth is arranged on circuit board 11 tops.The opening in labyrinth and circuit board 11 communicate.Electric wire can be electrically connected to labyrinth and circuit board 11 by this opening.The labyrinth comprises labyrinth seat 1 and labyrinth lid 4.In the utility model one preferred embodiment, labyrinth seat 1 is circular, and labyrinth lid 4 is the right cylinder of lower opening.Labyrinth seat 1 is arranged on circuit board 11.Labyrinth lid 4 is arranged on labyrinth seat 1, labyrinth seat 1 is encased form a darkroom 6.Labyrinth lid 4 is the hollow mesh structure.The hollow mesh structure of labyrinth lid 4 is key points of design of the present utility model.It not only effectively surveys with eliminating most important to smog; Simultaneously can also make dust be difficult for retaining in independent cigarette sense detecting alarm, reduce the wrong report of the independent cigarette sense detecting alarm that causes due to the dust scattering, improve the reliability of independent cigarette sense detecting alarm.In addition, because the hollow mesh structure of labyrinth lid 4 is evenly distributed, make smog can enter more equably the darkroom 6 in labyrinth from each orientation, improve sense cigarette efficient and detection performance; Simultaneously, also can play and prevent that insect from entering the effect in labyrinth.Cigarette sense probe unit is arranged in the labyrinth, and and circuit board 11 electrical connections.Cigarette sense probe unit comprises light source 2 and optical receiver 3.Light source 2 is used for the utilizing emitted light signal, and optical receiver 3 is used for receiving the light signal that light source 2 sends.Light source 2 and optical receiver 3 are separated by and are arranged on the outward flange of labyrinth seat 1.Diaphragm 7 in the middle of being provided with in the middle of labyrinth seat 1, middle diaphragm 7 is arranged between light source 2 and optical receiver 3.The effect of middle diaphragm 7 is that when effectively stoping non smoke, optical receiver 3 receives the light signal that light source 2 sends.Diaphragm 5 is arranged on the periphery in darkroom 6 on every side, and darkroom 6 is surrounded.The effect of border diaphragm 5 is to strengthen reflection of light intensity, effectively surveys smog.The audible alarm unit is fixedly installed on the downside of outer cover 8, and cigarette sense probe unit is electrically connected to.The audible alarm unit comprises sound cavity 13 and squealer spare 14.Sound cavity 13 is arranged on the top of sound device 14.
Whether independent cigarette sense detecting alarm can also comprise LED light 15, be used to indicate independent cigarette sense detecting alarm and work and the condition of a fire whether occurs.LED light 15 and circuit board 11 are electrically connected to.When the condition of a fire not occurring, the interval time of LED light 15 flickers is longer, and shows this independent cigarette sense detecting alarm normal operation, is in monitoring state.When the condition of a fire occurring, the interval time of LED light 15 flickers is short, is in alarm condition.
The smoke detection principle of independent cigarette sense detecting alarm of the present utility model is as follows: when producing the condition of a fire, the burning fire is arranged, produce imperfect combustion material, be smoke particle, simultaneously due to substance combustion, make ambient air temperature rise, smog spreads with hot-air, smog is diffused into around the labyrinth, and then enters in the darkroom 6 in labyrinth by fume inlet passage 9.The light scattering that smog sends light source 2, the light signal of optical receiver 3 receiving scattered light lines.The size of the light signal that optical receiver 3 receives just reflects the concentration of smog.The processing of the light signal that receives by circuit board 11, when the light signal that receives reached the calibration value of setting, the audible alarm unit began to report to the police, send chimes of doom, and the interval time of LED light 15 flickers is short, and the convenient condition of a fire of in time finding is effectively processed.
On the other hand, the smog that enters the labyrinth is subject to cross-ventilated effect, and smog reduces, and smog is diffused into outside the labyrinth.The light signal that receives when optical receiver 3 is during lower than the calibration value set, i.e. after labyrinth cleaning, independent cigarette sense detecting alarm reverts to monitoring state, audible alarm unit stop alarm, and alarm sound is eliminated automatically, and the interval time of LED light 15 flickers is longer.
The above is only the embodiment of utility model.Protection domain of the present utility model is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the utility model discloses, and the variation that can expect easily or replacement are within all should being encompassed in protection domain of the present utility model.
