Abstract

The utility model relates to a water saving device for a closestool, in particular to a single-chip microcomputer control device with multilevel flushing for a contact-free closestool. The utility model is characterized in that the control device is provided with two groups of field-effect tube induction devices and the field-effect tube induction devices respectively consist of a field-effect tube and a switching tube. A circuit of the switching tube is connected with the input end of a single-chip microcomputer. Output ends of the single-chip microcomputer are connected with input ends of two groups of the switching tubes with opposite polarities. The two groups of switching tubes with opposite polarities are connected with electromagnetical valve coils. An electromagnetical valve is installed at the water outlet end at the bottom of a water tank of the closestool. The single-chip microcomputer control device of the utility model has the advantages that the two groups of field-effect tube induction devices are defined as stool flushing of 6 L and urine flushing of 3 L which are provided for the selection of users. The single-chip microcomputer control device with multilevel flushing for the contact-free closestool overcomes the defects that closestool multilevel flushing devices of the prior art adopt contact-mode buttons for control, thus causing inconvenient use and cross infection.

Description

A kind of contact base closet of exempting from divides retaining flushing single chip machine control device

Technical field

The utility model relates to a kind of water-saving device of closet, and particularly a kind of contact base closet of exempting from divides retaining flushing single chip machine control device.

Background technology

The utility model is before the applying date, and the prior art toilet divides the retaining flushometer to adopt contact by key control, has the defective of using inconvenient and cross-infection.

Summary of the invention

The purpose of this utility model provides a kind of contact base closet of exempting from and divides retaining flushing single chip machine control device.

The technical scheme that its technical problem that solves the utility model adopts is: this device comprises the single-chip microcomputer imput output circuit; Its architectural feature is to have two groups of FET induction installations, the FET induction installation is made up of FET and switching tube respectively, the switching tube circuit is connected with the single-chip microcomputer input, the single-chip microcomputer output is connected with two groups of opposite polarity switching tube inputs, two groups of opposite polarity switching tubes are connected with electromagnetic valve coil, and electromagnetic valve is installed in toilet water tank bottom water side.

The beneficial effects of the utility model are that two groups of FET induction installations are defined as 6 liters of stool baths respectively and urine is washed by water 3 liters, select for use for the user.Overcome the prior art toilet and divided the retaining flushometer to adopt contact, had the defective of using inconvenient and cross-infection by key control.

Description of drawings

The utility model is described in further detail below by accompanying drawing.

Accompanying drawing 1 is an electrical schematic diagram of the present utility model.

The specific embodiment

Consult Fig. 1.Single-chip microcomputer is the PIC16C54 8-bit microcontroller of U.S. Microchip company among the figure.

This device comprises the single-chip microcomputer imput output circuit; Embodiment has two groups of FET induction installations, the FET induction installation is respectively by FET 3DJ6-1,3DJ6-1 and switching tube G1, G2 forms, switching tube G1, G2 circuit and single-chip microcomputer PIC16C54 input I/O (1), I/O (2) is connected, single-chip microcomputer PIC16C54 output I/O (3), I/O (4), I/O (5), I/O (6) and two groups of opposite polarity switching tube G3, G4, G5, the G6 input is connected, two groups of opposite polarity switching tube G3, G4, G5, G6 is connected with electromagnetic valve D coil, and electromagnetic valve D is installed in toilet water tank bottom water side.

Two groups of FET devices are defined as 6 liters of the stool baths and 3 liters of the baths of urinating respectively among the embodiment, select for use for the user.Single-chip microcomputer PIC16C54 is according to the difference of the FET voltage signal of switching tube G1, G2 output, and the electromagnetic valve D that control is installed in toilet water tank bottom water side opens and closes in limited time, realizes 6 liters or 3 liters of baths.Overcome prior art toilet stepping flushometer and adopted contact, had the defective of using inconvenient and cross-infection by key control.
