Abstract
A light control sanitary ware switch comprises a panel, a casing, an infrared launcher, a receiving joint and a circuit. The sanitary ware switch supplies power to an infrared receiving joint TLP947 by a 15V direct current battery, which uses an adjustable resistance with a voltage comparator LM311 and the absorption and composite resistance R4 of a control relay J, can regulate the measurement and control distance of the infrared receiving joint TLP947.
Description
A kind of automatic light control switch that is used on the sanitaryware, it is used for sanitary installation such as wash water pond, urinal, automatic hand dryer etc. and share sanitary installation.
This traditional field all is manually or in recent years to adopt the infra-red detection automatic switch by the end user, and its former unhygienic, causes the infection of disease easily, and its two circuit complexity costs an arm and a leg, and is not suitable for being extensive use of.
The deficiency that the inventor is intended to exist in the prior art is designed a kind of low cost, is fit to the infrared rays automatic switch of ordinary people needs, and its circuit is simple, easily makes.
The utility model is implemented by following technical solution, probe in the circuit adopts integrated infrared emission to receive head, the market model is TLP947, the resistance of circuit R4 wherein is transferred to the infrared rays measuring distance, and is installed in the panel back of packing in the worn-out box of small-sized screen.
For a kind of technical pattern that is used for the automatic light control switch on the sanitaryware of energy more detailed description the utility model, be described with reference to the accompanying drawings as follows:
Fig. 1 is a kind of automatic light control switch circuit diagram that is used on the sanitaryware of the utility model;
Fig. 2 is a kind of automatic light control switch external form figure that is used on the sanitaryware of the utility model.
See also Fig. 1, Fig. 2, automatic light control switch on these sanitaryware is by a panel 1, panel 1 be embedded with a transparent panel 2 and the rear portion is installed with casing 3, wiring board 5 is arranged in the casing 3, the concrete formation of its circuit is: power supply adopts lamination 15V in powered battery, make the transmitting tube conducting in the infrared emission reception head, through baffle reflection to receiving tube, cause resistance decreasing between the colelctor electrode of receiving tube and emitter stage, making voltage comparator LM311 output is high level, not adhesive of relay J, light quantity on being transmitted into receiving tube is covered by obstruction or when reducing, its colelctor electrode becomes big with the emission electrode resistance, circuit upset, the function of this utility model is finished in the adhesive of output low level relay thus.
In sum, the utility model is a kind of to be used for the automatic light control switch of sanitaryware on having and to have very big variation than this series products of prior art on electric line, and reduces unnecessary components and parts, and product cost reduces greatly.
Claims (1)
1, a kind of sanitaryware switch with light control functionality, it is made up of panel, casing, infrared rays emission, reception head and circuit.It is characterized in that: this sanitaryware switch is to give infrared receiving terminal TLP947 by direct current 15V powered battery, and its suction with voltage comparator LM311 control relay J is adopted adjustable resistances with closing resistance R 4, the observing and controlling distance of adjusting infrared receiving terminal TLP947.
