The emitting pole of the composite amplifier is connected with a control relay used for controlling the on-off of an incandescent lamp, and the front end of the control circuit is provided with a light control amplifier and a photoelectric coupler. The utility model has the advantages of high sensitivity, stable performance, electricity saving, and convenience.
Description
The utility model relates to a kind of improvement of electronic door bell.
The kind of electronic door bell is a lot of at present, but mostly is single doorbell function, does not have the function that the gate light short time can be opened simultaneously in night.
The purpose of this utility model provides and a kind ofly can trigger music integrated chip by sensing chip, gate light can be opened and the induction type economize on electricity Door bell with illumination of the certain hour of delaying time in night simultaneously.
The utility model is by housing, control circuit, music integrated chip, indication light emitting diode and photoelectrical coupler are formed, be provided with control circuit and indication light emitting diode in the doorbell housing, circuit inserts touch button by the three-core shielding line in the doorbell housing, touch button is provided with sensing chip and photodiode, photodiode inserts the base stage of light-operated amplifier, the emitter of light-operated amplifier links to each other with photoelectrical coupler, the output terminal Access Control circuit pre-amplifier of photoelectrical coupler, sensing chip is Access Control circuit pre-amplifier and driving circuit respectively, the output terminal of driving circuit links to each other with music integrated chip, and access loudspeaker, the output terminal of control circuit pre-amplifier inserts rc-delay circuit, rc-delay circuit links to each other with composite amplifier, the collector and emitter of composite amplifier is connected to indication light emitting diode and pilot relay respectively, is provided with rectification in electric power loop, voltage stabilizing, filtering circuit and incandescent lamp.
The utlity model has highly sensitive, stable and reliable for performance, characteristics such as a bell is used more, economize on electricity, convenience.
Accompanying drawing 1 is the utility model appearance structure synoptic diagram.
Accompanying drawing 2 is the utility model circuit theory diagrams.
Below in conjunction with accompanying drawing the utility model is further described, the utility model control circuit, music integrated chip is installed in the housing 1, shell is rectangular-shaped, panel top is provided with indication light emitting diode 2, internal circuit is linked to each other with touch button 4 by three shielding lines 3, touch button is provided with sensing chip 6 and photodiode 5, civil power inserts bridge rectifier behind resistance-capacitance depressurization, voltage stabilizing, filtering circuit 15, for control circuit provides operating voltage, sensing chip inserts the pre-amplifier 9 of illumination control circuit and the driving circuit 10 of music integrated chip simultaneously through dropping resistor, the structure of pronunciation circuit and principle of work are such, press sensing chip, the driving circuit conducting also makes music integrated chip 11 work sounding, plays the doorbell effect, capacitor C
4Can effectively prevent the external electric field interference, and adopt No.5 cell independently-powered, the structure of illumination control circuit and principle of work are such, when pressing sensing chip, pre-amplifier 9 conductings, after rc-delay circuit 12 time-delays, drive composite amplifier 13 conductings, the indication light emitting diode 2 that inserts the composite amplifier emitter is luminous, insert the pilot relay 14 conduction adhesives of emitter simultaneously, the incandescent lamp 16 that inserts the mains supply loop is luminous, the photodiode 5 that is arranged on the touch button receives light signal by day, input to light-operated amplifier 7, light-operated amplifier inputs to photoelectrical coupler with electric signal, its emitter output terminal blocks the control circuit pre-amplifier, illumination control circuit is not worked, incandescent lamp does not work, in the time of at night, because photodiode can't accept light signal, light-operated amplifier and photoelectrical coupler are not worked, the illumination control circuit pre-amplifier is unblanked, can directly be subjected to the control of sensing chip, in music integrated chip work, incandescent lamp is luminous, behind delay circuit work certain hour, incandescent lamp extinguishes automatically.
