Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Participate in Fig. 1, shown in Fig. 2, a kind of non-transformer is forgotten the alarm set that pulls key, comprise the installing plate 1 that can be connected with door surface engagement, on installing plate 1, connect motor 2 is set, the toggle being connected with doorframe is set on the motor shaft 21 of motor 2, correspondingly on installing plate 1, is equipped with the electric capacity 3, audible-visual annunciator 4, optical transmitting set 5 and the optical receiver 6 that are connected with motor 2 circuit.
Described installing plate 1 is provided with mounting hole, and installing plate 1 can be bolted to a surface by mounting hole, can certainly adopt the mode of viscose glue to be fixed on a surface.
Described toggle comprises the fixed bar 8 that support bar 7 that one end is fixedly connected with motor shaft 21 is fixedly connected with doorframe with one end, and the other end of support bar 7, fixed bar 8 is flexibly connected with the two ends of connecting rod 9 respectively.
Described electric capacity 3 is fixedly connected on installing plate 1 by fastener 10, can certainly select on other fixed form installing plates 1 such as viscose glue.
Described motor 2 one end and the anodic bonding of diode 22, described electric capacity 3 is anodal to be connected with diode 22 negative electrodes, negative pole is connected with motor 2 other ends, described optical transmitting set 5 comprises protective resistance 52, light emitting diode 51, and light emitting diode 51 negative electrodes are connected with electric capacity 2 negative poles, protective resistance 52 is connected with electric capacity 3 is anodal, described optical receiver 6 comprises resistance 62, photoresistance 61, and in parallel and electric capacity 3 two ends, described audible-visual annunciator 4 comprises protection diode 41, hummer 42, the transistor switching circuit that triode 43 forms, described transistor switching circuit collector, emitter is parallel to electric capacity 3 two ends, base stage connects between resistance 62 and photoresistance 61.
Motor 2 is at closing time, it is upper just lower negative that motor 2 rotates the electricity sending, now can charge to electric capacity 3 by diode 22, for whole circuit supply, light is sent in light emitting diode 51 work in optical transmitting set 5, when having key in recess 11, photoresistance 61 cannot receive light, photoresistance 61 resistances in optical receiver 6 become large, triode 43 conductings, and hummer 42 sends alarm sound.When in recess 11 during without key, the photoresistance 61 in optical receiver 6 receives light, and photoresistance 61 resistances diminish, and triode 43 is obstructed, and hummer 42 is not worked.In the time opening the door, due to motor 2 rotate the electricity sending be upper negative under just, now diode 22 is obstructed, cannot charge to electric capacity 3, whole circuit is obstructed.
