Abstract

The utility model relates to a device for controlling a timing on/off circuit, which belongs to a timing control circuit. The output terminal of an AC transformer is connected with a diode 1 which is connected with a capacitor C, a diode 2 and a relay. After connected, the relay and the diode 2 are connected with a thyristor. The buzzer of the electronic timer is connected with a diode 3. The negative pole of the electronic timer, the thyristor and the capacitor C are connected with the AC transformer. The relay is connected with the alternating current voltage of 220V, and is also connected with a socket which is connected with the alternating current voltage of 220V. The device can be used in the power utilization load such as timing cooking, ringing, etc. with the advantages of time saving and no power consumption.

Description

A kind of control device of timing on/off circuit

The utility model relates to a kind of control device of timing on/off circuit, belongs to a kind of in the electronic timing on/off circuit arrangement.

Efficient modernized fast rhythm of life requires people more effective to utilization and the arrangement of time, and the daily life trival matters of every day will consume the many valuable time of people, make between work, life and the amusement to clash.Such as, to treat every day After Hours to go home again to cook, the time of once cooking calculated by 30 minutes, just needed one hour on 1st by secondary calculating, just needed more than 360 hours in 1 year in 1st.And, sometimes catch up with and be in a hurry, people but can only helplessly wait rice, and the rice is done says again, if just electric rice cooker is connected socket during working, so, electric rice cooker since long-time heating one be the waste electric energy, the 2nd, cause rice mouthfeel not good, school regularly goes to school and leaves school and rings a bell etc. for another example, also exists the problem that the special messenger regularly nurses.

The purpose of this utility model is the control device that a kind of timing on/off circuit is provided at the problem that exists in the above-mentioned daily life, with the liberation labour, improves the time availability in the daily life.

The technical solution of the utility model is: the alternating voltage of the input of AC transformer and 220 volts joins, the positive pole of the output of AC transformer links to each other with the positive pole of diode 1, the negative pole of diode 1 and the positive pole of capacitor C, the negative pole of diode 2, P terminal 5 joins, P terminal 6, after joining, the positive pole of diode 2 links to each other with the positive pole of thyristor, the buzzer positive pole of electronic timer links to each other with the positive pole of diode 3, the negative pole of diode 3 extremely links to each other with the control of thyristor, the negative pole of the buzzer of electronic timer, the control utmost point of thyristor, the negative pole of capacitor C and the negative pole of AC transformer join, the binding post 7 of relay and the positive pole of 220 volts of alternating voltages join, the normally opened contact binding post 4 of relay links to each other with a termination terminal of socket, the other end binding post 9 of socket links to each other with the negative pole of 220 volts of alternating voltages, and the binding post 8 of relay is a normally-closed contact.

The utility model has the advantages that electronic circuitry design is simple, easy to make, used electric elements are all the conventional electrical appliance element, cost is low, in not power consumption of waiting time, on/off supply line on time, the utility model has a style of one's own, volume is little, can connect the different electric loadings of using on its socket according to different needs.

Accompanying drawing is a circuit diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model is elaborated:

The input of a 3-5W 220V/24V AC transformer 10 and the civilian alternating voltage of 220V join, the positive pole of the output of 3-5W 220V/24V AC transformer 10 links to each other with the positive pole of IN4001 type diode 1, the positive pole of the filter capacitor C of the negative pole of diode 1 and withstand voltage 50V, the negative pole of IN4001 type diode 2, having two pairs often opens, the binding post 5 of the 12V relay 15 of normally-closed contact joins, the binding post 6 of relay 15, the positive pole of diode 2 joins afterwards and the IN4001 type, withstand voltage 400V, the positive pole of the thyristor 11 of 1A links to each other, the positive pole of buzzer 13 that has the electronic timer 12 of time reporting function links to each other with the positive pole of IN4001 type diode 3, the control utmost point of the negative pole of diode 3 and thyristor 11 joins, the control utmost point of thyristor 11, the negative pole of the buzzer 13 of electronic timer 12, the negative pole of capacitor C links to each other with the negative pole of 3-5W220V/24V AC transformer 10, the binding post 7 of relay 15 links to each other with the positive pole of 220 volts of alternating voltages, the binding post 4 (normally opened contact) of relay 15 links to each other with a termination terminal of socket 14, the other end binding post 9 of socket 14 links to each other with the negative pole of 220V alternating voltage, and the binding post 8 of relay 15 is normally-closed contacts.Usefulness such as electric rice cooker, electric bell electric loading can be directly and socket 14 join.
