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 transfer circuit. The transfer circuit is connected with the input end of a single-chip microcomputer. The output end of the single-chip microcomputer is connected with input ends of two groups of 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 respectively defined as stool flushing of 6 L and urine flushing of 3 L which are provided for users to choose. 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
Technical field
The utility model relates to a kind of water-saving device of closet, particularly a kind of contact base closet stepping flushing single chip machine control device of exempting from.
Background technology
