Description

Automatic energy-saving timing switch

The utility model relates to a kind of appliance switch, and particularly a kind of electricity-saving type Auto-delay switch is applicable to various lightings automatic time delay control switch, also is applicable to other electric equipment automatic time delay control switch.

At present, the Auto-delay switch that uses in the society has many kinds, but it is complicated mostly to have circuit design, manufacturing cost is higher, the shortcoming of be difficult for popularizing, in recent years, people have worked out also that the design of some models is comparatively simple, the new type auto delay switch of low cost of manufacture, but it is narrow mostly to have range of application, the shortcoming that technical performance is relatively poor.

Task of the present utility model is to provide a kind of simple in structure, low cost of manufacture, is easy to popularize, electricity saving performance is good, switch is flexible, novel electricity-saving type Auto-delay switch applied widely.

Task of the present utility model realizes with following scheme:

Accompanying drawing has provided electrical schematic diagram of the present utility model.

The utility model is formed by connecting in the following manner:

Two power lines of civil power 220V alternating current respectively with by rectifier diode D ₁～D ₄It is side a and b that the input of the rectification circuit of forming is connected, and controlled lighting or controlled electric appliance DX are serially connected in wherein any one of two power lines, by rectifier diode D ₁～D ₄The both positive and negative polarity of the output of the rectification circuit of forming respectively with corresponding being connected of both positive and negative polarity of controllable silicon SCR, the input of rectification circuit is B end and rectifier diode D ₅Positive terminal be connected rectifier diode D ₅Negative pole end be connected with the stiff end of push-button switch S, another stiff end of push-button switch S is connected with the positive terminal of capacitor C, the other end of capacitor C is connected resistor R with the negative pole end of controllable silicon SCR ₃Be attempted by on the capacitor C, the positive terminal of capacitor C passes through by resistor R ₄With variable resistance R ₂Be connected resistor R with the trigger electrode of controllable silicon SCR behind the series circuit of forming ₁Be attempted by on the trigger electrode and negative pole of controllable silicon SCR resistor R ₅An end be connected the other end and light-emitting diode D with the positive pole of controllable silicon SCR ₆Positive terminal be connected light-emitting diode D ₆Negative pole end and the input of rectification circuit be that the A end is connected.

Below with reference to accompanying drawing operation principle of the present utility model is described as follows:

During work push-button switch S is pressed, at this moment civil power 220V alternating current is through rectifier diode D ₅After the rectification to capacitor C charging, be higher than the trigger voltage of controllable silicon SCR when the charging voltage on the capacitor C after, i.e. resistor R ₁After the trigger voltage of both end voltage greater than controllable silicon SCR, the one-way SCR conducting that just is triggered, at this moment civil power 220V alternating current is by controlled lighting or controlled electric appliance DX, by rectifier diode D _1～4Rectification circuit, controllable silicon SCR, the formation current circuit formed, controlled lighting or controlled electric appliance DX energising work, light-emitting diode D simultaneously ₆, resistor R ₅Energising, light-emitting diode are lighted.After the release button switch S, the control loop power supply is cut off, the electric charge on the capacitor C passes through resistor R ₃And resistor R ₄, variable resistance R ₂, resistor R ₁The discharge loop discharge of forming, when the voltage on the capacitor C was lower than silicon controlled trigger voltage device after discharge, controllable silicon was closed, and cut off the power supply of lighting or controlled electric appliance DX, the current path of light-emitting diode also is cut off simultaneously, thus the task that realization is cut off the electricity supply automatically.The ON time of controllable silicon SCR, promptly controlled lighting or controlled electric appliance electrical working time are by the size of the capacitance of capacitor C with by resistor R ₁, R ₃, R ₄And variable resistance R ₂Resistance value decision, adjust variable resistance R ₂Or change the capacity of capacitor C or change resistor R ₁, R ₃, R ₄The resistance time that just can realize changing the controllable silicon conducting can change conduction time of controlled lighting or controlled electric appliance, thus, people can determine conduction time according to actual needs, when for example being used for the control lighting hours of dormitory building passageway lighting lamp, people can determine the illuminating lamp burning time as required.

In sum, energising of the present utility model is determined by push-button switch S, as long as push-button switch S is pressed, the voltage on the capacitor C promptly is charged to the trigger voltage of controllable silicon SCR at instantaneous time, and controlled lighting or controlled electric appliance DX are in the moment that push-button switch S the presses work of can switching on.The time-delay electrical working time of controlled lighting or controlled electric appliance DX is by container C and resistor R ₁, R ₃, R ₄And variable resistance R ₂The RC circuit of forming determines that the utility model is selected resistor R for use ₂Be that a variable resistance is definite for regulating the on-delay time, therefore, when people use the utility model, can oneself adjust variable resistance R according to actual needs ₂Resistance adjust the length of delay time, manufacturer also can adjust amount of capacity and the resistor R of capacitor C according to user's different needs ₁, R ₃, R ₄With variable resistance R ₂Size adjust delay time.

That push-button switch S of the present utility model its resistance when being off-state is is infinitely great, therefore do not consume any electric energy, and when push-button switch S was conducting state, its complete machine operating current was also very little, can ignore, so can realize the purpose of economizing on electricity.
