Description

A kind of infrared inductor

Technical field

The utility model relates to intelligent lighting field, particularly a kind of infrared inductor.

Background technology

Infrared inductor is the automatic control product based on infrared technology, comprises induction tap, automatic hand dryer, medical hand washer, automatic soap dispenser, induction urinating bucket water-flushing device, induction closet.In the time having people to enter induction range, sensor special detects the variation of human body infrared spectrum, automatically connects load, and people does not leave induction range, will continue to connect; After people leaves, automatic delay function load.People is bright to lamp, and people puts out from lamp, and warm convenient, energy-saving safe, more demonstrates concern with humanization.

The inductive head lower cover that existing infrared inductor comprises base upper cover, matches the base that is connected, matches the bottom that is connected, is arranged at the universal joint between base upper cover and base, the binding post that is arranged at bottom and wire hole O-ring seal, the rotary body that is arranged at base, circuit grillage, semicolumn, wiring board, eyeglass, eyeglass pressing plate, is arranged at the inductive head middle cover of rotary body, is connected with inductive head middle cover with base with base upper cover.

Realizing in 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 binding post that covers under described, be arranged on wire hole O-ring seal on described lower cover wire hole, be arranged on middle cover in described lower cover, be fixed on the wiring board that covers in described, be fixed on eyeglass on described wiring board, be arranged on time potentiometer and sensitivity potentiometer on described wiring board, be arranged on cover in described the potentiometer knob of perforate, with the described lower cover cover arranging that matches; In described, cover perforate outer rim and be provided with scale.

Particularly, described wiring board is screwed in described and covers.

Particularly, described eyeglass is fixed by snap on described wiring board.

Particularly, described time potentiometer is connected respectively described potentiometer knob with described sensitivity potentiometer.

Particularly, described cover is fixed together with described middle cover and described lower cover by buckle.

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

External form uniqueness, cover is fixed together with middle cover and lower cover by four buckles, compact conformation; The knob place of adjusting time indicates scale, can directly select the length of working time when user uses, easy to use.

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.

Fig. 1 is the STRUCTURE DECOMPOSITION figure of the infrared inductor that provides of the utility model embodiment;

Fig. 2 is the front view figure of the infrared inductor that provides of the utility model embodiment;

Fig. 3 is the vertical view of the infrared inductor that provides of the utility model embodiment;

Fig. 4 is the rear view of the infrared inductor that provides of the utility model embodiment.

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.

Embodiment

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 binding post 2 on lower cover 1, be arranged on wire hole O-ring seal 3 on lower cover 1 wire hole, be arranged on middle cover 4 in lower cover 1, be fixed on wiring board 5 on middle cover 4, be fixed on eyeglass 6 on wiring board 5, be arranged on time potentiometer and sensitivity potentiometer on wiring board 5, be arranged on the potentiometer knob 7 of perforate on middle cover 4, with lower cover 2 cover 8 arranging that matches.

Particularly, binding post 2 is arranged on lower cover 1, is used for accessing electric wire.

Particularly, middle cover 4 and lower cover 1 are screwed, and on middle cover 4, perforate outer rim is provided with scale.

Particularly, wiring board 5 is screwed on middle cover 4.

Particularly, eyeglass 6 is fixed by snap on wiring board 5.

Particularly, time potentiometer is connected respectively potentiometer knob 7 with sensitivity potentiometer, and two potentiometers while rotating potentiometer knob 7 like this on adjustable wiring board regulate the ambient light of product to require and the effect of working time thereby can play.

Particularly, cover 8 is fixed together with middle cover 4 and lower cover 1 by buckle.

The utility model infrared inductor sensing part 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.Assemble the infrared ray of 10 microns of left and right, the light of other wavelength of filtering with special Fresnel Lenses, the light that can effectively get rid of environment disturbs.Product, within the scope of induction region, detects that the probe of infrared induction when human body moves with 0.30～3 meter per second PIR specially changes the low frequency signal of 0.1-10HZ into it, amplifies and processes pilot relay through infrared special chip.In the time having people movable within the scope of induction region, lamp is bright, time delay certain hour automatic distinguishing after ending activity.Adopt relay contact zero passage technology, the contact that lights point relay at induction back light contacts at the near zero-crossing point exchanging.Greatly reduce the impact of power supply to product and load.Because having used relay contact zero passage technology, product has strengthened doubly a lot of to capacitive load serviceable life.

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.
