Synchronous motor type electronic switch

Abstract

The invention relates to a synchronous motor type electronic switch, which has simple and convenient setting and vivid display. The switch comprises a shell, a socket component which can be directly inserted into a power socket, a power switch with a self-locking function, a reducing mechanism with a synchronous motor, a power supply output socket and a disc with graduation, wherein a circle of jacks are uniformly distributed at a position, which corresponds to the power switch, on the disc; one or more bolts are inserted into the jack; and switch-on and switch-off of the power switch can be controlled effectively by the switch when the bolt rotates in the disc. The electronic switch has the advantages of controlling the power-off time of an electrical appliance after electrification, setting the electrification time of the electrical appliance after power failure, prolonging the service life of the electrical appliance and saving electric energy, along with novelty, practicability, low manufacturing cost, stable and safe performance and no effect to the use effect of a user who frequently forgets an electrical appliance plug.

Description

technical field [0001] The invention relates to a synchronous motor type electronic switch with timing function. Background technique [0002] Although the electronic timers in the prior art have high travel time accuracy, due to the complicated setting process, they are not suitable for the use of low-educated people, the elderly and children. If there is no programming manual, it is impossible to set the time on and off. . For example, the Chinese utility model patent CN01200948.2 discloses a timer schedule setting structure, which mainly controls the rotation of the rotating disk arranged on the outer edge of the setting disk in the clockwise / counterclockwise direction, so that the circuit has the function of setting time and division. Function, although the time setting of this kind of timer can be accurate to minutes, but its whole setting process is very loaded down with trivial details. Although the current mechanical timer has the advantage of convenient setting, i...

Problems solved by technology

Although the current mechanical timer has the advantages of convenient setting, it has disadvantages such as high cost and short timing time. In addition, there is a single timing and cannot be used for combined timing.
