Abstract
The utility model discloses an automatic fire alarming device which comprises a thermistor (1) and an electromagnetic switch (3). Iron core coils of the thermistor (1), a first power source (2) and the electromagnetic switch (3) are connected through wires to form a first loop. The two ends of an alarming device body (4) are electrically connected with two binding posts of the electromagnetic switch (3) respectively through wires to form a second loop. A second power source (7) is connected in the second loop. The automatic fire alarming device has the advantages of being simple in structure, and low in production cost, the work principle of the automatic fire alarming device is simple, the misinformation phenomenon cannot occur, and the failure rate is low.
Description
Technical field:
The utility model relates to warning device technical field, more specifically to a kind of fire automatic alarm device.
Background technology:
Near people can reminding in time for fear of fire or when fire occurs, therefore people have designed various fire alarm installations, we relatively common are the warning devices such as infrared warning device and smoke alarm, the feature of these warning devices is that their line construction is complicated, production cost is higher, can not reach universal, can only in large-scale supermarket or office building, use, but also can regular appearance report by mistake or the phenomenon of damage, the cost of maintenance is also higher.
Utility model content:
The purpose of this utility model is just to provide a kind of fire automatic alarm device, and it is simple in structure, the feature that production cost is lower, and also the utility model principle of work is simple, there will not be the phenomenons such as wrong report, and failure rate is lower.
For achieving the above object, a kind of fire automatic alarm device of the present utility model comprises a thermistor and an electromagnetic switch, the iron-core coil of thermistor, the first power supply and electromagnetic switch connects and composes the first loop by wire, the two ends of warning device are electrically connected formation second servo loop with two binding posts of electromagnetic switch respectively by wire, in described second servo loop, are connected with second source.
As technique scheme preferably, described thermistor is NTC type thermistor.
As technique scheme preferably, the domestic power supply that described the first power supply and second source are 220V.
As technique scheme preferably, described the first power supply and second source are lithium battery.
As technique scheme preferably, in described the first loop, be connected with a controller.
As technique scheme preferably, described second source is connected with display lamp by wire, described second source is connected on a binding post of electromagnetic switch by wire by wire and display lamp.
As technique scheme preferably, described warning device consists of alarm lamp and emergency alarm bell.
The beneficial effects of the utility model are: the utility model is by the situation of change of the characteristic induction indoor temperature of thermistor, it is simple in structure, the feature that production cost is lower, and also the utility model principle of work is simple, there will not be the phenomenons such as wrong report, failure rate is lower.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model
In figure: 1, thermistor; 2, the first power supply; 3, electromagnetic switch; 4, warning device; 5, display lamp; 6, controller; 7, second source; 41, alarm lamp; 42, emergency alarm bell
Embodiment:
Therefore the following stated only, for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model
Be illustrated in figure 1 the embodiment of a kind of fire automatic alarm device of the utility model, it comprises a thermistor 1 and an electromagnetic switch 3, the iron-core coil of thermistor 1, the first power supply 2 and electromagnetic switch 3 connects and composes the first loop by wire, the two ends of warning device 4 are electrically connected formation second servo loop with two binding posts of electromagnetic switch 3 respectively by wire, are connected with second source 7 in described second servo loop.
In addition, in the present embodiment, thermistor 1 is NTC type thermistor.
The first power supply 2 and second source 7 can be also lithium battery source for the domestic power supply of 220V, and for easy to use, and in order to have longer serviceable life, the utility model adopts lithium battery as power supply.
In the present embodiment, be connected with a controller 6 in the first loop, this controller plays electric current and voltage situation in monitoring the first loop.
Second source 7 is connected with display lamp 5 by wire, and described second source 7 is connected to by wire on a binding post of electromagnetic switch 3 by wire and display lamp 5, and this display lamp 5 shows under normal circumstances, is generally green work display lamp.
Warning device 4 consists of alarm lamp 41 and emergency alarm bell 42, and in the present embodiment, alarm lamp 41 is red flashing lamp, can play better the effect of prompting.
Principle of work of the present utility model: thermistor 1 is installed in indoor with indoor air and contacts, but when indoor temperature raises, the resistance of NTC type thermistor diminishes, the electric current in the first loop increases, electromagnetic switch 3 work, now second servo loop work, alarm lamp 41 and emergency alarm bell 42 send alerting signal, acting as of controller 6, when air themperature is under normal situation, this controller 6 makes the first loop be off-state, resistance at NTC type thermistor diminishes, when controller 6 both end voltage raise, the first circuit communication in the time of to the particular value of a setting, controller 6 can play energy-conservation effect, prevent from occurring wrong report under normal situation about heating up simultaneously, can be so that work of the present utility model be more accurate.
