Abstract
The utility model discloses a contact-free water saving device for a train closestool of a motor train set and relates to a closestool water saving device, in particular to a dual photoelectricity induction contact-free water saving device for a train closestool of a motor train set. The dual photoelectricity induction contact-free water saving device for a train closestool of a motor train set is characterized in that two groups of photoelectricity induction devices are provided and the photoelectricity induction device is composed by the connection of a light dependent resistor and a transfer circuit. A non-inverting input of the transfer circuit is connected with the LDR and an inverting input of the transfer circuit is connected with a fixed power source. The output end of the transfer circuit is connected with the input end of a single-chip microcomputer and the output end of the single-chip microcomputer is connected with the 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 and an electromagnetical valve is connected in series at both ends of a flush pipe of the closestool. The dual photoelectricity induction contact-free water saving device for a train closestool of a motor train set is defined as stool flushing of 6 L and urine flushing of 3 L which are provided for the selection of users and overcomes the defect that a photoelectricity flushing device for the train closestool of the motor train set in the prior art is only provided with a single photoelectricity sensor, thus the stool flushing and the urine flushing can not be separated. Therefore, the dual photoelectricity induction contact-free water saving device for a train closestool of a motor train set is favorable to saving water.
