Description
Technical field
This utility model relates to a kind of doorbell, specifically a kind of Multifunctional touching doorbell.
Background technology
Doorbell is electronic equipment conventional in daily life, can effectively help the people in user notice room, therefore suffer from liking of people, but existing door bell lamp is used mostly key switch control, the mechanical contact of key switch is easily damaged, the service life causing doorbell reduces, once button damages, doorbell just cannot use, usual people can directly abandon, generally it is accomplished by one or two years changing, and existing doorbell can only send jingle bell sound, high-end doorbell can send musical sound, but for the old people that audition is bad, it is difficult to hear the sound that doorbell sends, therefore just cannot be suitable for, make troubles to this kind of crowd.
Utility model content
The purpose of this utility model is in that to provide a kind of Multifunctional touching doorbell, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of Multifunctional touching doorbell, including electrode slice M, audion V1, chip IC 1 and bidirectional thyristor Q1, the base stage of described audion V1 connects electric capacity C3, the other end of electric capacity C3 connects electrode slice M, the colelctor electrode of audion V1 connects power supply VCC, the emitter stage of audion V1 connects electric capacity C1 and loudspeaker B, another section of electric capacity C1 connects the negative electrode of diode D1 and the pin 1 of chip IC 1, the other end of loudspeaker B connects the anode of diode D1 and the pin 2 of chip IC 1 ground connection, the pin 3 of chip IC 1 connects resistance R1, the base stage of the other end connecting triode V2 of resistance R1, the emitter stage of audion V2 connects the negative electrode of diode D2, the anode of diode D2 connects stroboscopic lamp H and 220V alternating current, the colelctor electrode of audion V2 connects resistance R2, the other end of resistance R2 connects electric capacity C2 and resistance R3, the other end of electric capacity C2 connects the pin 4 of chip IC 1, one main electrode of bidirectional thyristor Q1 and the other end of 220V alternating current, the other end of resistance R3 connects the control pole of bidirectional thyristor Q1, another main electrode of bidirectional thyristor Q1 connects the other end of stroboscopic lamp H, described chip IC 1 is 4N25 photo-coupler.
As preferred version of the present utility model: described power supply VCC is 9V unidirectional current.
Compared with prior art, the beneficial effects of the utility model are: this utility model Multifunctional touching doorbell circuit simple in construction, components and parts are few, use touch manner controls, add the service life of switch, on the basis of original jingle bell, add stroboscopic lamp simultaneously, it is suitable for the bad people of audition to use, therefore there is the advantage that life-span length, cost are low and easy to use.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of Multifunctional touching doorbell.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of Multifunctional touching doorbell, including electrode slice M, audion V1, chip IC 1 and bidirectional thyristor Q1, the base stage of described audion V1 connects electric capacity C3, the other end of electric capacity C3 connects electrode slice M, the colelctor electrode of audion V1 connects power supply VCC, the emitter stage of audion V1 connects electric capacity C1 and loudspeaker B, another section of electric capacity C1 connects the negative electrode of diode D1 and the pin 1 of chip IC 1, the other end of loudspeaker B connects the anode of diode D1 and the pin 2 of chip IC 1 ground connection, the pin 3 of chip IC 1 connects resistance R1, the base stage of the other end connecting triode V2 of resistance R1, the emitter stage of audion V2 connects the negative electrode of diode D2, the anode of diode D2 connects stroboscopic lamp H and 220V alternating current, the colelctor electrode of audion V2 connects resistance R2, the other end of resistance R2 connects electric capacity C2 and resistance R3, the other end of electric capacity C2 connects the pin 4 of chip IC 1, one main electrode of bidirectional thyristor Q1 and the other end of 220V alternating current, the other end of resistance R3 connects the control pole of bidirectional thyristor Q1, another main electrode of bidirectional thyristor Q1 connects the other end of stroboscopic lamp H, described chip IC 1 is 4N25 photo-coupler.
Power supply VCC is 9V unidirectional current.
Operation principle of the present utility model is: when there being people to come to visit, Touching electrode M, when the finger of people touches electrode slice M, the induced signal of human body is added in the base stage of audion V1 by electric capacity C3, audion V1 is turned on, then doorbell loudspeaker B sounding, now audio voltage can pass through diode D1, electric capacity C1 inputs to the 1 of photoelectrical coupler IC1, 2 feet, light emitting diode within IC1 can turn on, then its internal transistor also turns on, audion V2 turns on, the C2 colelctor electrode by V therewith, after R2, C2 is charged, C2 both end voltage rises, when C2 raised voltage reaches the trigger voltage value of bidirectional thyristor Q1, then Q1 triggering and conducting and to make stroboscopic lamp H obtain electric, send passage of scintillation light.After turning on due to Q1, C2 has certain time through R3 to the electric discharge of Q1 trigger electrode, therefore, Q1 conducting can time delay, time when continuing certain, after C2 discharge off, Q1 can cross zero to cut-off；Cutting off stroboscopic lamp H power supply, circuit enters idle and waits for peacefully state, waits the triggering of next time.
