Description

A kind of delay switch of scalable delay time

The utility model relates to a kind of household electrical appliance that are used for, the delay switch of the scalable delay time of especially civilian corridor lighting.

A lot of closely during the last ten years people are studying aspect the domestic lighting lamp switch, multiple the novel switched of good energy-saving effect that have occurred, as audio-switch, and delay switch etc.; The subject matter that these switches exist is that delay time is short, and open and close are frequent, and bulb very easily damages, and causes the useful life of switch and bulb shorter.

The purpose of this utility model provides a kind of long switch of delaying time, and delay time is adjustable.

The technical scheme that realizes above-mentioned purpose is, this delay switch comprises panel, transmission mechanism, quartz electronic alarm clock movement and decompression rectification power four parts, button connection gear transmission mechanism on the panel, gear drive is connected with quartz electronic alarm clock movement, and the spring leaf that links to each other with alarm clock movement links to each other with circuit controling switch; For providing the step-down rectifying circuit of power supply and circuit controling switch, quartz electronic alarm clock is in series in load circuit.

Because adopt such scheme, the delay switch delay time is long, can reach a few hours, and delay time is adjustable, guarantee that whole evening, street lamp all had electricity, avoid switch and bulb frequent starting, prolong its useful life, adopt quartz electronic alarm clock movement, cost is low, and is easy to make, simple in structure.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of this delay switch.

Fig. 2 is the switch panel schematic diagram.

Fig. 3 is 1/4 Knucle-gear part drawing.

Fig. 4 is shaft sleeve parts figure.

Fig. 5 is the retaining sheet part drawing.

Fig. 6 is quartz electronic alarm clock front elevation.

Fig. 7 is circuit theory diagrams.

Switch panel 9 profiles are similar to existing switch panel, there is a button 10 in central authorities, one time-delay set screw is arranged above button, can control the rotational angle of 1/4 Knucle-gear, what link to each other with button is one 1/4 Knucle-gear 8 (as Fig. 3), pushes button 10,1/4 Knucle-gear rotates an angle, decontrol button, under the effect of return spring, 1/4 Knucle-gear is got back to reset condition again.

As shown in Figure 1, transmission device central shaft 6 links to each other with quartz electronic alarm clock movement 1, is set with transmission device support chip 7, return spring 5, retaining sheet 4, axle sleeve 3 on central shaft 6 successively.The structure of axle sleeve 3 as shown in Figure 4, it is enclosed within alarm clock and rings on the time pin central siphon that makes a noise, the axle sleeve outer rim has 12 oblique tooths 12, and the braking spring screens with dress on the circuit board 2 can only rotate counterclockwise it, and control axle sleeve rotational angle, such as, when axle sleeve turned over for 3/4 week, alarm clock was with regard to regularly 3 hours, when axle sleeve turned over for 1/2 week, then alarm clock was with regard to regularly 6 hours.Axle sleeve 3 fronts have 4 oblique teeth 13 to contact with retaining sheet 4, have on the retaining sheet 4 two can only one-directional rotation ratchet 14, retaining sheet and a pinion 15 are fixed together, this pinion and the engagement of 1/4 Knucle-gear, when 1/4 Knucle-gear rotated, pinion was the retaining sheet rotation, drove axle sleeve 3 simultaneously and rotated, correspondingly drive alarm clock movement and rotate, play the effect of stirring time pin; Button unclamps, and then return spring 5 makes retaining sheet get back to initial condition, for regularly action is ready next time.This transmission mechanism only is a specific embodiment, should belong to category of the present utility model as long as actuation of keys can be converted to the transmission mechanism of the action of stirring time pin.

As shown in Figure 6, the lower position of quartz electronic alarm clock movement has a square aperture 16, in have alarm clock control to ring the spring leaf that makes a noise, plastic boss 17 of edge on this spring leaf, with the circuit board 2 of square opening correspondence position on a reed switch K is installed, when starting timer clock, the projection on the spring leaf is pushed reed switch K, and circuit is connected, when being timed to, projection on the spring leaf is unclamped, break spring K switch then, circuitry cuts.

Its circuit theory is in series with reed switch K as shown in Figure 7 in civil power and load L loop, and step-down rectifying circuit, and step-down rectifying circuit is by transformer B, and bridge rectifier Q forms, and it is exported AC1.5V and uses for quartz electronic alarm clock movement.

Why the utility model adopts quartz electronic alarm clock movement to make delayer, and reason has three, and first delay time is long; It two is that volume is little, and it three is that cost is low.Adopting step-down rectifying circuit is that the quartz clock power supply is to avoid often changing battery, practicality easy to use.
