Abstract

An intelligent energy-saving and electroshock-proof socket for water fountains is characterized in that a time setting circuit is composed of a clock setting key, a start time setting key and a LCD, all of which are respectively connected with an input terminal and an output terminal of a SCM chip. An ultrasonic sensor circuit is composed of an ultrasonic sensor, an ultrasonic drive module and a gate circuit and connected with a human induction signal and the input terminal of the SCM chip. In addition, a null ground wire potential difference detecting device is composed of a transformer, a rectifying device and a switch tube and connected with the input terminal of the SCM. An output terminal of a diode switching circuit is connected with a relay coil. A normally open contact of a relay is respectively connected with a live wire and a null wire. The present invention has the benefits that a power source of an electric heating tube is automatically cut off during water fountain operation, at a specific time or during idle operation. The null ground wire potential difference detecting device provides a leakage signal of the electric heating tube and eliminates defects of electrified water due to electric heating tube leakage and endangering personal safety.

Description

technical field [0001] The invention relates to an electricity-saving and anti-electricity socket, in particular to an intelligent energy-saving and anti-electricity socket for a water dispenser. Background technique [0002] Before the present invention, the power plug of the water dispenser was directly inserted into the wall socket, and it was heated repeatedly no matter day or night and whether someone used it, resulting in waste of power resources. When the water dispenser socket is not grounded, the leakage of the electric heating tube will lead to electrification in the water, endangering the personal safety of the user. Contents of the invention [0003] The purpose of the present invention is to provide an intelligent water dispenser power-saving and anti-electricity socket. [0004] The technical scheme that the present invention solves its technical problem is: the present invention comprises ultrasonic sensor and zero ground potential difference detecting devi...
