Abstract
The utility model relates to an additional deaf person call circuit of doorbell in the field of household door control, which comprise a doorbell horn ML; the utility model is characterized in that the two ends of Al and A2 of the doorbell horn ML are connected with the input end of an opto-coupler GO; the control pole of controllable silicon TL is connected with the output end series resistance R of the opto-coupler GO and then is connected with the anode of the controllable silicon TL; the series color lamp string of the anode of the controllable silicon TL is connected with a power plug CT; and the cathode of the controllable silicon TL is directly connected with the power plug CT. The utility model has the advantages of simple structure, and convenient mounting; moreover, the additional deaf person call circuit of doorbell mounted on the original doorbell can solve the reliability of the deaf person or the old to receive the doorbell information.
Description
Technical field
The utility model relates to the additional deaf person's call circuit of a kind of doorbell in family expenses gate field.
Background technology
At present family's doorbell is only for the normal person uses, and when being in as the deaf person that has only the hearing deficiency in the family or old man, guest's calling is rather difficult.
Summary of the invention
The purpose of this utility model is exactly the defective that exists at prior art, the additional deaf person's call circuit of the doorbell that provides a kind of energy to be fit to deaf person or old man.
Its technical scheme is: comprise doorbell loudspeaker ML, it is characterized in that: the A1 of doorbell loudspeaker ML, A2 two ends connect the input end of optocoupler GO, the output terminal resistance in series R that is connected optocoupler GO by the control utmost point of controllable silicon TL is connected to controllable silicon TL anode, controllable silicon TL anode series connection Color lamp string L is connected to attaching plug CT, and the negative electrode of controllable silicon TL is directly connected to attaching plug CT.
The utlity model has simple in structure, install additional conveniently, be installed at and can solve the reliability that deaf person or old man receive doorbell information on original doorbell.
Description of drawings
Accompanying drawing is the circuit theory diagrams of a kind of embodiment.
Embodiment
Be further described below in conjunction with accompanying drawing: the A1 of doorbell loudspeaker ML, A2 two ends connect the input end of optocoupler GO, the output terminal resistance in series R that is connected optocoupler GO by the control utmost point of controllable silicon TL is connected to controllable silicon TL anode, controllable silicon TL anode series connection Color lamp string L is connected to attaching plug CT, and the negative electrode of controllable silicon TL is directly connected to attaching plug CT.
Principle of work: attaching plug CT inserts power supply, and when the guest pressed doorbell, the doorbell audible warning was transferred to optocoupler GO through A1, A2, make its conducting, power supply triggers controllable silicon TL conducting through resistance R, optocoupler GO, and Color lamp string L obtains power supply and sparkles, and reaches the prompting purpose.
