Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the automatic water-feeding device for the closestool comprises a probe A2 and a probe B3 which are respectively arranged at the top and the bottom of the closestool 1, a pipeline for communicating a tap water port is arranged at one side of the top end of the closestool 1, an electromagnetic valve DF4 is arranged on the pipeline, the electromagnetic valve DF is controlled by a control circuit to be powered off when the probe A2 and the probe B3 are switched on and powered off when the electromagnetic valve DF is controlled by the control circuit to be powered off,

The resistance values of these elements in fig. 2 are well known and can be adjusted as required by those skilled in the art.

The working principle of the utility model is as follows: when a power switch SA is pressed, a 220V power supply is changed into 12V through a transformer B1, and then is rectified through a rectifier stack UR, filtered through an electrolytic capacitor C1, and stabilized by a three-terminal voltage stabilizing integrated circuit IC1 to obtain stable direct current power supply.

When the water level of the toilet bowl 1 reaches a certain amount, the probe A2 and the probe B3 are switched on due to water contact, the base electrode of the transistor BG1 is short-circuited, the transistor BG1 is cut off, the relay J1 is powered off, the electromagnetic valve DF4 is powered off, and therefore water supply to the toilet bowl is stopped. Once someone flushes the toilet, the probe a2 and the probe B3 are disconnected again, the transistor BG1 is conducted again, and the process is circulated continuously, so that the function of automatic water supply is achieved.
