Description

Batch (-type) Automatic Cycle step-less adjustment timing switch

The utility model relates to a kind of timing switch, relates in particular to batch (-type) step-less adjustment timing switch.

Now, the employed timing switch of various electrical equipment can only time opening or cut out, and can not open in timing/stop than adjusting, perhaps carries out the control of Automatic Cycle step-less adjustment, causes energy-conservation and automatic control to be difficult to handle, and makes troubles to use.

The purpose of this utility model is exactly in order to overcome the deficiency of above-mentioned technology, to adopt digital integrated circuit, and by inner frequency division and step-less adjustment frequency of oscillation, the batch (-type) of opening/stop time ratio of energy Automatic Cycle control electrical appliance is electronic switch regularly.

The technical solution of the utility model can be: by resistance, and electric capacity, rectifier diode, the batch (-type) Automatic Cycle step-less adjustment timing switch that triode is formed, capacitor C 2 wherein, resistance R 4 and rectification module BR1 form step-down rectifying circuit; Capacitor C 3 inserts by voltage stabilizing didoe Z1, triode Q2, the voltage stabilizing circuit that resistance R 5 is formed; Resistance R 1, R2, capacitor C 1, integrated circuit cmos forms oscillating circuit; Diode D1, D2, resistance R 3, triode Q1, relay J 1 is formed the driving executive circuit.

Described circuit is provided with regularly and opens/stop 6 grades of scores, opens/stops than being 0.5 '/2 ' to 4.5 '/14 ', from 0.5 to 4.5 minute opening time, closes down from 2 to 14 minutes time.

The utility model adopts digital integrated circuit, and time ratio is opened/stopped to the realization step-less adjustment, can Automatic Cycle control, and can set arbitrarily; Circuit is simple, the reliability height; Load capacity is strong, and is low in energy consumption, good energy-conserving effect.

Now be illustrated in conjunction with the accompanying drawings and embodiments.

Fig. 1 is the utility model electricity schematic circuit.

Fig. 2 for the utility model open/between the stopping time than knob floor map.

The utility model adopts insulation, flame retardant plastics shell knob, and built-in circuit constitutes.Its operation principle as shown in Figure 1.The control core adopts digital integrated circuit, realizes step-less adjustment, Automatic Cycle control.After the energized, turn linked switch potentiometer K, switch is in opening, and power supply is through decompression capacitor C2, resistance R 4, rectification module BR1 forms step-down rectifying circuit; DC power supply inserts after capacitor C 3 filtering by voltage stabilizing didoe Z1, triode Q2, and the voltage stabilizing circuit voltage stabilizing that resistance R 5 is formed provides the stabilized voltage power supply of a 10V backward; Resistance R 1, R2, capacitor C 1, integrated circuit cmos forms oscillating circuit, and its cycle is 2.2R2C1, triggers the cmos integrated circuit, and frequency division counter makes integrated circuit cmos, and triode Q8, Q9 (13,14 pin) export high level respectively; By diode D1, D2, resistance R 3, triode Q1, relay J 1 is formed and is driven executive circuit, and control relay J1 contact on/off reaches the purpose of control apparatus On/Off.RST end (12 pin) ground connection with integrated circuit cmos automatically resets integrated circuit cmos, makes the work of circuit Automatic Cycle.Regulate resistance R 2, then can change the frequency of oscillation of circuit, and the variation that reaches step-less adjustment and open/stop time ratio.Also can bring in the adhesive/release that changes relay J 1 by Q8, the Q9 among the reconfiguration integrated circuit cmos and control the action/stand-by period of electrical appliance.By the normally closed/normally opened contact J1-1 of reconfiguration relay J 1, can make original opening/stop counter-rotating, realize Automatic Cycle.LED is a frequency of oscillation indicator light 4, can directly show the oscillating circuit operating state.When extinguishing, oscillating circuit failure of oscillation, counting circuit stop counting, and the level of corresponding output remains unchanged, and is the oscillator starting of oscillation when LED is glittering, and circuit is in definition status.

During use, this circuit is inserted supply line, the power supply phase line inserts the input of the phase line 1 of this switch, and zero line connects the input of this switch zero line 2.The input phase line 1 of this switch connects the phase line input of electrical appliance, and the zero line input of electrical appliance can directly connect zero-power line or connect the input of the zero line 2 of this switch.Rotation is opened/is stopped than knob 5, makes timing switch be in the ON/OFF position, and energized, ON/OFF just enter the timing working state, regulates and to open/to stop than knob 5, can obtain different opening/stop than timing.When electrical appliance needs operation continuously, only need when opening this switch need are opened/stop directly to be threaded on the standard-sized sheet point 6 and get final product than knob 5.When regularly needing electrical appliance to move continuously midway, timing switch can be in lowly when opening/stopping than state, with regularly opening/stop the position that is threaded to standard-sized sheet 6 than knob 5 electrical equipment is moved continuously.If need to recover regularly, as long as directly rotation is opened/stopped than knob 5 to a certain opening/stop can recover definition status than position (as 2 '/6 ').Regulate indication than opening on the knob 5/stop than scale and open/stop and compare the time with opening/stopping.As show that it is 0.5 '/2 ' that minimum is opened/stop than time location, and then showed time opening 0.5 minute, regularly closed down 2 minutes, open/stop than being 1/4; If what demonstration was maximum opens/stops than time location to be 4.5 '/14 ', then to show time opening 4.5 minutes that timing was closed down 14 minutes, opened/stopped than about 1/3.2.
