In realizing process of the present utility model, inventor finds that prior art at least exists following problem:

Existing small product size is bigger than normal, and moulding is not attractive in appearance.

Summary of the invention

In order to solve the problem of prior art, the utility model embodiment provides a kind of infrared inductor.Described technical scheme is as follows:

The utility model embodiment provides a kind of infrared inductor, described infrared inductor comprises lower cover, be arranged on the spring covering under described, be arranged on the first wiring board in described lower cover, correspondence is arranged on the semicolumn in described lower cover, be fixed on the second wiring board on described semicolumn, be arranged on time potentiometer and sensitivity potentiometer on described the second wiring board, the potentiometer knob being connected with described sensitivity potentiometer with described time potentiometer respectively, with the fixing middle cover of described lower cover, be fixed on the upper cover covering in described, be fixed on the eyeglass pressing plate and the eyeglass that cover on described.

Particularly, described semicolumn is fixed on the pillar that described lower cover is corresponding; Described the second wiring board is fixed on described semicolumn.

Particularly, on described the second wiring board, be connected with time potentiometer and sensitivity potentiometer, connect respectively described potentiometer knob; Described potentiometer knob is through the perforate covering in described.

Preferably, described middle cover is fixed together by screw and described lower cover.

Preferably, described upper cover is fixed by snap covers in described.

Preferably, described eyeglass pressing plate, described eyeglass are fixed together by buckle and described upper cover.

The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:

The utility model overall dimensions are small and exquisite, compare with other like products, done larger variation in appearance and modeling, also realized dimensionally miniaturization; Used relay contact zero passage technology, product extends capacitive load serviceable life simultaneously.

Accompanying drawing explanation

In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

The utility model embodiment provides a kind of infrared inductor, referring to Fig. 1 to Fig. 4, described infrared inductor comprises lower cover 1, be arranged on the spring 2 on lower cover 1, be arranged on the first wiring board 3 in lower cover 1, correspondence is arranged on the semicolumn 4 in lower cover 1, be fixed on the second wiring board 5 on semicolumn 4, be arranged on time potentiometer and sensitivity potentiometer on the second wiring board 5, the potentiometer knob 6 being connected with sensitivity potentiometer with time potentiometer respectively, by screw and the fixing middle cover 7 of lower cover 1, upper cover 8 on middle cover 7 fixed by snap, eyeglass pressing plate 9 and eyeglass 10 on upper cover 8 fixed by snap.

Particularly, spring 2 is arranged on lower cover 1.

Particularly, semicolumn 4 is fixed on the pillar of lower cover 1 correspondence, then the second wiring board 5 is fixed on semicolumn 4.

Particularly, on the second wiring board 5, connect and be provided with time potentiometer and sensitivity potentiometer, connect respectively potentiometer knob 6, potentiometer knob 6 is through the perforate on middle cover 7, time potentiometer and sensitivity potentiometer while rotating potentiometer knob 6 like this on adjustable the second wiring board 5, thus can play the working time length of this infrared inductor and the effect of induction sensitivity of regulating.

Particularly, middle cover 7 is fixed together by screw and lower cover 1.

Particularly, upper cover 8 is fixed by snap on middle cover 7.

Particularly, eyeglass pressing plate 9, eyeglass 10 fixed by snap with upper cover 8 together with.

The sensing part of the infrared inductor that the utility model embodiment provides adopts the induction installation of passive infrared beta radiation, and the wavelength that utilization is sent human body is that the pyroelectricity element of the sensitive for infrared radiation of 10 microns of left and right is surveyed mobile human body.With special-purpose Fresnel Lenses, assemble the infrared ray of 10 microns of left and right, the light of other wavelength of filtering, the light that can effectively get rid of environment disturbs.

The infrared inductor that the utility model embodiment provides is within the scope of induction region, and when human body being detected and moving with 0.30～3 meter per second, infrared induction probe PIR specially changes the low frequency signal of 0.1-10HZ into it, through infrared special chip, amplifies and processes pilot relay.When having people movable within the scope of induction region, lamp is bright, time delay certain hour automatic distinguishing after ending activity.

The infrared inductor that the utility model embodiment provides adopts relay contact zero passage technology, and after induction, lamp lights, and the contact of point relay, in the near zero-crossing point contact exchanging, effectively reduces the impact of power supply to product and load.

The beneficial effect that the technical scheme that the utility model embodiment provides is brought is: the utility model overall dimensions are small and exquisite, compares with other like products, has done larger variation in appearance and modeling, has also realized dimensionally miniaturization; Used relay contact zero passage technology, product extends capacitive load serviceable life simultaneously.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
