Detailed advantage of the present utility model is as follows:
1, existing free-standing detector darkroom size is larger, and identical acceptance can increase infrared emission electric current in sensitivity situation, thereby detector power consumption is increased.What is more important, the darkroom structure of large-size, can make the corresponding increase of physical dimension of whole detector.The utility model is by the design of unique darkroom, cleverly smog dredge with infrared light stop, reflection configuration, detection darkroom size is dwindled.The path that the detection darkroom dwindling makes tube-launched Infrared arrive infrared receiving tube after smog scattering shortens, compared with large scale darkroom, guarantee the identical sensitivity of accepting, the electric current of the required transmitting of infrared transmitting tube is less, thereby reduces the overall power of detector.Prior, the darkroom size of dwindling makes whole detector realize small and exquisite physical dimension becomes possibility.
2, existing free-standing smoke detector sound part is generally individual devices, can additionally increase detector size, in the situation of generation same sound pressure grade, needs to consume larger electric current.The utility model sound part directly adopts and drives buzzing sheet vibration sounding, detector upper cover is carried out to accurate sounding resonant cavity design simultaneously, buzzing sheet is fixed on to cover with it with fluid sealant and combines together, compared with adopting independently sound device, reach identical acoustic pressure grade, the electric current that sound combination of the present utility model needs is less, thereby reduces the overall power of detector.Prior, by the combination of buzzing sheet and detector top cover, save the shared space of independent sound device, the one-piece construction of stacked compactness is achieved.
3, the each element combinations of existing free-standing detector not adopts stacked structure, have more parallel layout (such as: survey darkroom and sound device in same plane; Battery and wiring board are in same plane etc.), can not form compact structure combination, thereby make detector physical dimension comparatively huge.The utility model is detector upper cover, acoustical generator, detector darkroom, drain pan, battery and detector mounting bracket, creationary employing stack design, and the closely orderly vertical cartel that carries out, thus the physical dimension of detector is greatly reduced.
4, existing free-standing smoke detector all has comparatively huge physical dimension, small and exquisite not, while installing and using, there is more inconvenience (such as the whole style that: installing space is limited, affect installation site, be not easy to carry out with other products integrated combination etc.).The utility model, in guaranteeing detector performance, has reduced product power consumption, has improved the serviceable life of battery, has reduced detector volume.Can more be widely used in multiple place, solve and cause installing, be not suitable for the situation of installing because of small product size.Reducing of small product size, makes detector can be easy to carry out integrated and combination with other products, has widened the usable range of detector.
5, existing free-standing smoke detector battery generally only can use 1 year, quotes later the not enough fault of cell voltage.Service time of battery is shorter, needs often to change battery.The utility model is by reducing to survey the size in darkroom, and combined circuit design reduces to survey the required infrared emission electric current of smog, thereby reduces the stand-by power consumption of whole product.Adopt the battery of same charge, increased the service time of detector, prolongation user changes the cycle of battery, meets the general direction of energy-conserving and environment-protective.
6, not directly disassembly, cleaning of the Air Filter of present free-standing smoke detector, convenience is not high.The utility model top cover adopts rotary structure, by screwing off top cover, can be easy to carry out the dismounting of fly net.In the time that detector meets with comparatively serious dust or foreign body obstruction fly net, this function can allow user carry out easily the cleaning of fly net, extends the serviceable life of detector.
7, existing separate detectors is bulky, and cost is higher.The utility model compact conformation, production technology is simple, easy for installation.Starting material and production, installation, maintenance cost significantly reduce.In the situation that meeting standard, greatly improve the cost performance of product.
