Embodiment four:
Referring to Fig. 5, Fig. 6, Fig. 7, Fig. 8 A, Fig. 8 B, Fig. 8 C, Fig. 5 is applied to the practical circuit diagram of a power induction switch for the present invention, wherein this IC is in the shown plural inductor of Fig. 4 41,42,43 any, it connects and includes alternating current conversion direct current (AC/DC) rectification circuit, a relay (Relay) and other relevant control circuits, when we with finger during near inductor (being IC), this relay can receive the output signal of inductor and move, and its switch inside switched to the below, can conducting one electric light luminous; Moreover when we desire to close electric light, only need near inductor with finger, this relay is received from the output signal of inductor and moves, and its switch inside is switched to the top, electric light will extinguish naturally, and connect a light-emitting diode (LED) luminous (being the display unit 47,48,49 that Fig. 4 discloses), and make us in dark, still can find the position of this power induction switch.
Traditional electronic inductor such as electrostatic induction device, be the change of nationality by the object static coefficient of conductivity of being responded in the electric field, produce corresponding induced signal, nationality obtains a drive signal by the processing of other electronic circuit components again, and, make suitable work disposal (referring to Fig. 6) with the element that this drive signal control is connected.The inductive effects of the inductor of above-mentioned conventional art, in a specific range, can respond to various complex medias individually, but when touching complex media, then can't differentiate, promptly can't do the induction of selecting type to object, as to water, metal, proportions such as human body are equal to or greater than 1 electing property of material or are distinguished according to the different of the difference of its coefficient of conductivity and material proportion and mass density, and only can have no optionally to be responded to, and on the work disposal of induction, the difference that different distance of reaction also can't then be arranged the various unlike materials of the last adding of distance of induction significantly makes and uses the restriction that certain degree is arranged.
Integrated circuit (being IC part shown in Figure 5) is very similar with the electrostatic induction device of conventional art, when the difference between the two is that the conventional electrostatic inductor touches medium this medium is responded to, so can't do induction to the material beyond this medium again, and integrated circuit (IC) there is no this defective, it is except the function that the conventional electrostatic inductor is arranged, and can see through and outwards to continue again to respond to by predetermined medium, and this predetermined medium there is no and be defined as which kind of material, all can so long as have the material of quality.Integrated circuit (IC) is by the inductor that can adjust susceptibility, under the control of using a control unit is adjusted, reach the control of a certain distance of reaction and the electrostatic induction device that wisdom is selected induction, to solve the shortcoming that to do selective induction in the prior art in the past, and do further design via different electronic components, can manufacture and design as Related products such as inductive switch, automatically control, antitheft and countings, and reach more efficient Yu the more handy purpose of product more in the past.
Wherein integrated circuit (IC) be nationality by being provided with a sensing unit in the inductor, receive a triggering signal, this sensing unit is a susceptibility (referring to Fig. 7) of being controlled its induction by a control unit adjustment.Triggering signal can be under being separated by of a medium or plural different medium, with this medium as structure as the intermediate dielectric layer of electric capacity, which kind of material this dielectric layer then is not defined as, under suitable selecting for use, as long as the material of static electrification is arranged, all can be used as middle dielectric layer induction work can be carried out under the setting of a suitable dielectric layer; And be provided with down at this dielectric layer with a suitable height, this dielectric layer can be the space interval of certain distance, promptly at a distance of one suitably apart from the time, but nationality is responded to received signal by integrated circuit (IC), and make suitable work disposal, and this material more can make inductor respond to the object of the distance of a certain degree through selecting for use down.But also nationality thus the sensing unit of integrated circuit (IC) add that one has quite the dielectric layer of height, make range distance increasing, the augmentation of induction, at various height, the selecting for use of material and the different medium of plural number down, make scope that the present invention can respond to, apart from increasing; And nationality is by after adjusting this controller, make this sensing unit work distance and trigger sensitivity adjustment in various degree, the controller of this sensing unit not only can be arranged at inner each unit of sensing unit and connect setting, can also external mode become a self-contained unit, this sensing unit is done control adjustment.
The height of dielectric layer will be because of the quality and the electrical conductivity of medium itself, and have influence on its external distance of reaction and scope, its account form is calculated according to Coulomb's law and newton's gravitation and the resistance of medium (ohmic value), for example: an integrated circuit adjustment can be responded to the A as Fig. 8 to certain material at 1mm, above with integrated circuit under the condition, place the thick glass of a 5mm, its distance of reaction is 10mm such as Fig. 8 B, above with integrated circuit under the condition, place the thick glass of a 10mm, its distance of reaction is 20mm such as Fig. 8 C, if place the glass after two blocks of thick glass of 5mm also just equal 10mm, its result such as Fig. 8 C distance of reaction are 20mm, above with integrated circuit under the condition, place the thick ceramic tile of a 7mm, its distance of reaction but has only 2mm, its reason that produces different distance of reaction is that its quality of different material is neither identical, therefore distance of reaction also is not quite similar, and because of the kind of its dielectric layer can be divided into: conductor, semiconductor, insulator etc., and this also produces different induction ranges, so the complex of different material also has different distance of reaction and induction range, thereby can't make certain distance of reaction to integrated circuit (IC), and the control adjustment of its available control unit, reach the control of a certain distance of reaction and the electrostatic induction device that wisdom is selected induction.
If need make integrated circuit (IC) some specific range or material are done an induction, need inform that then integrated circuit manufactory please it adjust influence value, if the scope that changes influence value is among a small circle the time, the same magnitude of voltage of adjusting with the conventional electrostatic inductor of its adjustment gets final product.
