AI Technical Summary

Technical Problem

In existing linear actuators, the electromagnets in the stator assembly are arranged in a vertical state, which increases the length of the device in the vertical direction and occupies more space, affecting the product appearance and space utilization.

Method used

The electromagnet is arranged horizontally, and the magnet group is set on the side of the electromagnet corresponding to its magnetic pole. Through electromagnetic induction, the magnet group moves back and forth along the direction perpendicular to the central axis of the electromagnet, making full use of the horizontal space and reducing the height of the device.

Benefits of technology

By improving the structure of the linear actuator, its length and lateral proportions are coordinated, which improves the appearance of the product, reduces the occupied space, and improves space utilization.

Abstract

The utility model relates to the technical field of linear motors, and particularly discloses a linear actuating device and a hair cutting device, which are characterized in that an installation frame is arranged, an electromagnet is horizontally arranged in an electromagnet installation part, and a magnet group is arranged in a magnet group installation part; after alternating current is supplied to the electromagnet, the magnet set can be promoted to move in a reciprocating mode in the direction perpendicular to the center axis of the electromagnet through the magnetic induction effect of the electromagnet and the magnet set. The electromagnet is horizontally arranged, and meanwhile, the magnet group is arranged on the side of the electromagnet and is opposite to the magnetic pole of the electromagnet, so that the transverse space can be fully utilized, the height of the linear actuating device is greatly reduced, the length of a product adopting the linear actuating device is reduced, and the proportions of the linear actuating device in the length direction and the transverse direction are coordinated; the aesthetic feeling of the product appearance is improved.
