Abstract
The utility model discloses a smoke alarm. The smoke alarm includes an alarm housing, a substrate, smoke detectors, a signal processing circuit and an alarming device. The smoke alarm includes at least four smoke detectors. At least three smoke detectors are uniformly distributed on the outside housing of the substrate. The fourth smoke detector is mounted on the lower end the alarm housing. The four smoke detectors are arranged to form an inverted cone. The smoke detectors are parallelly connected with the signal processing circuit. The signal processing circuit is connected with the alarming device. By the above manner, the smoke alarm is able to detect smoke generated by fire in a multi-dimensional detection manner. The design of the inverted cone smoke detectors ensures more accurate detection, and thus the smoke alarm can raise the alarm.
Description
Technical field
The utility model relates to alarm field, particularly relates to a kind of smoke alarm.
Background technology
Fire is often accompanied by dense smoke while generation, but general alarm device is arranged on roof, and sniffer is arranged on the central authorities of alarm, the in the situation that of long-time no cleaning, alarm surrounding has probably been piled up a large amount of dusts, and while generation due to fire, wind direction is indefinite simultaneously, smog is along with wind direction is also indefinite, in the time that fire occurs, can have influence on the detection of alarm like this, and then slow down sending and fire rescue work of alarm of fire.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of smoke alarm, can improve the accuracy of detection of fires generation smog, for building safety provides safeguard.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of smoke alarm is provided, comprise: alarm housing, pedestal, smoke detector, signal processing circuit and warning device, described smoke detector comprises at least four smoke detectors, described at least three smoke detectors are evenly distributed on outside described pedestal on housing, described another smoke detector is arranged on described alarm housing lower end, described four smoke detectors are reverse taper, described smoke detector and described signal processing circuit are connected in parallel, described signal processing circuit is connected with warning device.
In preferred embodiment of the utility model, described alarm housing is connected with described base thread, in described alarm housing, is provided with external thread, and described pedestal is provided with internal thread, and described external thread is connected with described internal thread.
In preferred embodiment of the utility model, described signal processing circuit comprises signal receiving module and signal processing module, and described signal receiving module is connected with signal processing module, and described smoke detector and signal receiving module are connected in parallel.
In preferred embodiment of the utility model, in described warning device, be provided with alarm, described alarm is connected with signal processing module.
In preferred embodiment of the utility model, in described warning device, be also provided with an alarm display lamp, described alarm display lamp is located on described alarm housing.
In preferred embodiment of the utility model, alarm is loudspeaker.
The beneficial effects of the utility model are: the utility model can the smog producing occur multi-faceted detection of fires, and the design of reverse taper smoke detector can be surveyed more accurately, thereby gives the alarm.
