Problems solved by technology

However, during operation, since the top 111 of the solenoid valve shaft 11 will collide with the bottom 1022 of the groove, a collision sound will be generated.
The collision sound will be amplified by the structure of the solenoid valve device 1 and converted into a low-frequency sound. Human beings are very sensitive to this low-frequency sound, so as long as a small low-frequency sound will make human beings feel unpleasant, this makes most users feel quite troubled

Abstract

The invention relates to a solenoid valve device and an automatic paper feeder using the same. The solenoid valve device comprises a solenoid valve body, a solenoid valve shaft center, a spring, an annular groove and a muffling ring, wherein the annular groove surrounds the solenoid valve shaft center and is provided with the muffling ring. When the solenoid valve body is excited to adsorb the solenoid valve shaft center, the solenoid valve shaft center moves in the solenoid valve body and enables the muffling ring to collide with the solenoid valve body to reduce the colliding sound.

Description

technical field [0001] The invention relates to a power device, in particular to a solenoid valve device for converting electric energy into magnetic energy and an automatic paper feeder utilizing the solenoid valve device. Background technique [0002] The solenoid valve device is a device used to convert electrical energy into magnetic energy, and is widely used in various fields. In order to meet the needs of different devices, manufacturers of solenoid valve devices manufacture solenoid valve devices of various sizes according to various needs. [0003] For the structure of the solenoid valve unit, please refer to figure 1 , which is a structural schematic diagram of an existing solenoid valve device.
