Abstract
The utility model discloses a zero static power dissipation alarm which consists of an electronic acoustic alarm, a trigger control circuit and a shell. A signal input terminal of the electronic acoustic alarm is connected with the trigger control circuit which consists of a time delay control integrated circuit block, a resistance, a capacitance, a controller, a diode, a triode, a power supply and a trigger control switch which are all connected. The utility model has the advantage of basically no consumption of power in a waiting status, thus guaranteeing the alarm to have sufficient electric energy in alarming work and improving the working reliability of the alarm.
Description
Technical field:
The utility model relates to a kind of zero quiescent dissipation alarm, belongs to the electronic alarm technical field.
Background technology:
At present, electronic alarm of the prior art mainly exists the shortcoming that also will consume certain electric energy when holding state.Owing to there is this shortcoming, electronic alarm of the prior art electricity phenomenon with regard to having run out of before also not sending chimes of doom of its power supply often occurs in use.Therefore the functional reliability of existing electronic alarm still is not ideal enough.
Summary of the invention:
The purpose of this utility model is: provide a kind of when holding state the zero quiescent dissipation alarm of consumed power not substantially, overcoming the deficiencies in the prior art, thereby improve the functional reliability of existing alarm.
The utility model is to constitute like this: it comprises electronics sonic alarm (1) and housing (3), signal input part in electronics sonic alarm (1) is connected with trigger control circuit (2), trigger control circuit (2) is by time delays control integrated circuit piece IC1, resistance R 1～R4, capacitor C 1～C5, controllable silicon BR, diode D1, triode BG1, power supply E, power switch K1, triggering gauge tap K2 forms, R1, R3, R4, D1, C1, C2, C4, the end of C5 and K2 and the control utmost point of BR all are connected with IC1, and R3, R4, C1, C2, another termination power cathode of C4, the control output end of IC1 is connected with the base stage of BG1, the collector of BG1 is connected with the negative electrode of the other end of C5 and BR, the emitter of BG1 is connected with C3 and R2 with the signal input part of electronics sonic alarm (1), the negative pole of another termination power E of C3 and R2, the positive pole of power supply E connects anode and the other end of K2 and the power supply input positive terminal of electronics sonic alarm (1) of BR, and electronics sonic alarm (1) and trigger control circuit (2) all are contained in the housing (3); On housing (3), be provided with the connection socket (4) and the standby power supply socket (5) that trigger gauge tap K2, and triggering gauge tap K2 can be a microswitch or two above microswitches compose in parallel.
Owing to adopted technique scheme, the utility model is compared with existing alarm, the utlity model has when holding state substantially the not advantage of consumed power, thereby guaranteed that alarm has sufficient electric energy and carries out work when warning work, therefore improved the functional reliability of alarm.When using the utility model, to trigger the place that gauge tap K2 is positioned over needs warning earlier, and make it be in more hidden position and be touched easily, then power switch K1 is closed, at this moment the utility model is in holding state, because K2 does not have trigger pip, not conducting of controllable silicon BR, therefore the power supply that leads to trigger circuit (2) and electronics sonic alarm (1) all is cut off, thereby reaches under holding state the not purpose of consumed power; When touching trigger switch K2, IC1 obtains positive voltage, its output control terminal produces a control signal immediately, make the BG1 conducting, thereby high potential signal of BG1 output is to electronics sonic alarm (1), make it send alarm sound, after through 20～40 second time (this time is by the time constant decision of R1 and C1), the IC1 upset, its control output end stops output, BG1 ends because of signal out of hand, at this moment controllable silicon turn-offs, and makes complete machine be in standby garrison state again, after this, if trigger switch K2 is triggered once more, then the utility model is and for example gone up process and is equally sent alarm sound.
Description of drawings:
Accompanying drawing 1 is a principle schematic of the present utility model;
Accompanying drawing 2 is a schematic appearance of the present utility model;
Accompanying drawing 3 is the circuit theory synoptic diagram of the utility model embodiment.
Embodiment:
