Description

Device and beauty instrument for electromagnetically driving linear reciprocating motion

This invention involves the field of linear reciprocating motion technology, and in particular, involves a device that uses electromagnetics to drive linear reciprocating motion and a beauty instrument that uses the device that uses electromagnetics to drive linear reciprocating motion.

At present, some linear reciprocating mechanisms include motors, eccentric wheels, and connecting rods. The output shaft of the motor is connected to one end of the eccentric wheel, and the other end of the eccentric wheel is connected to the connecting rod. The motor drives the eccentric wheel to move, and the eccentric wheel drives the connecting rod to perform linear reciprocating motion. This mechanism has the defects of large size and complex structure.

At present, there is also a linear reciprocating motion mechanism, including an electromagnetic unit, which includes multiple magnetic cores and coils, and the multiple magnetic cores and coils are arranged at intervals. After the coil is energized, the magnetic core is magnetized, so that the magnetic core generates a magnetic field, and the magnetic field is used to attract or repel the vibrating body to achieve up and down reciprocating motion. The defects of this mechanism are: on the one hand, a large space is required to install multiple magnetic cores and coils arranged at intervals, and the volume is large; on the other hand, the magnetism sensed by the vibrating body in the middle of the magnetic core is small, the reaction is slow, and the movement efficiency is low.

This invention aims to at least solve the technical problems of large size, complex mechanism and low magnetic induction efficiency in the existing technology. To this end, this invention proposes a device that uses electromagnetic drive to drive linear reciprocating motion, which can greatly reduce the size and improve the sensitivity of motion response.

According to an embodiment of the invention, a device for electromagnetically driven linear reciprocating motion includes: a bracket, a magnetic body, a vibrating body and an elastic body, wherein the bracket has a first accommodation space, the magnetic body and the vibrating body are located in the first accommodation space, one end of the magnetic body is connected to the bracket, a coil is wound around the periphery of the vibrating body, the elastic body is connected to the end of the bracket and closes a port of the first accommodation space, and one end of the vibrating body is connected to the elastic body.

The magnetic body has magnetism, with one end being an N pole and the other end being an S pole. When the magnetic field generated by the coil near one end of the magnet is N, it repels the N pole of the magnetic body, and the vibrating body moves linearly away from the magnetic body. When the magnetic field generated by the coil near one end of the magnet is S, it attracts the N pole of the magnetic body, and the vibrating body moves linearly toward the magnetic body, and the cycle repeats in sequence, thereby realizing linear reciprocating motion. During the linear reciprocating motion process, the vibrating body carries the elastic body to perform linear reciprocating motion. Since the elastic body is connected to the bracket, it acts as a limiter on the vibrating body, limiting the vibrating body to perform linear reciprocating motion in the first containing space.

The magnetic body 100 is magnetic, with one end being an N pole and the other end being an S pole. When the magnetic field generated by the coil 7 near one end of the magnet 11 is N, the N pole of the magnetic body 100 is repelled, and the vibrating body 200 moves linearly in a direction away from the magnetic body 100.
