Abstract
The utility model belongs to the field of electronic timing switch power supply, which is characterized in that electrical signals from an electronic alarm clock are simultaneous input a timing de-energising circuit and a timing energising circuit which comprises a low-voltage relay, and can continuously supply electric for the timing energising circuit and the timing de-energising circuit via the self-holding contact of a circuit, wherein the timing de-energising circuit comprises a double-base diode and a miniature relays. The device has the advantages of low fabrication cost, large timing range, convenient operation, and reliable service.
Description
The utility model belongs to the electric timing switch field of power supplies.
Existing electronic timing device belongs to auxiliary products more, generally is applied to lighting circuit.The timing switch that is applied to household electrical appliance all is special-purpose, and also not having a kind of electric timing switch device on the market is current collection period of the day from 11 p.m. to 1 a.m clock, switch, socket product.Therefore, be badly in need of this series products of exploitation to satisfy the demand in market.
The purpose of this utility model is to provide a kind of timing to lead to switching device, and this device can be directly used in the power consumption equipment between single-phase 220V, the 10W-1200W.
This timing exchange device, form by plastic casing (2), power supply indicator (3), circuit board (4) and accessory power outlet (5) etc., it is characterized in that: mounting circuit boards on the base plate of plastic casing (2) (4) and accessory power outlet (5), shell (2) is gone up the electronic alarm clock (1) of mounting strap quarter-bell; Electronic alarm clock (1) the output signal of telecommunication becomes low-voltage direct by after transformer coupled, the triggering bidirectional triode thyristor conducting by voltage drop element and rectification circuit; This DC power supply, the timing power-on circuit of forming for simultaneously the timing power-down circuit formed by unijunction transistor and miniature relay and low-voltage relay; And be the electric circuit supply of regularly switching continuously by the circuit self holding contact, and to make accessory power outlet be electric.
Drawings and Examples:
Fig. 1 is regularly the exchange device structural representation.
Fig. 2 is regularly the schematic block circuit diagram of exchange device.
Accompanying drawing the 1, the 2nd, the disclosed embodiment of the utility model (seeing Fig. 1, Fig. 2), electronic alarm clock (1) are determined the switching electricity time, and single-phase socket (5) connects the electrical equipment of being controlled.During use, at first, regularly connecting on the power supply, bright the reddening of power supply indicator (3) at this moment, indication device on power supply then, is inserted into the attaching plug of institute's control electrical equipment on the accessory power outlet of this device, and just can control electrical equipment this moment.Stir the electronic alarm clock pointer, point to institute and fix time, then power supply indicator (3) is bright turns green, expression accessory power outlet on power supply, and appliances power source is also connected simultaneously, and electrical equipment is started working.
The utility model cost is low, timing range is big, easy and simple to handle, reliable, the timing power on/off that can be used for household electrical appliance is used, and also can regularly water for the rural area hot house, regularly heats, regularly ventilate and use.
Claims (1)
1. exchange device regularly, comprise shell (2), electronics indicator light (3), circuit board (4) and accessory power outlet compositions such as (5), it is characterized in that: mounting circuit boards on the base plate of plastic casing (2) (4), accessory power outlet (5) and electronic alarm clock (1), electronic alarm clock (1) the output signal of telecommunication, simultaneously to the power-on circuit of being made up of unijunction transistor and miniature relay, and by the circuit self holding contact is regularly switching electricity circuit supply continuously.
