Abstract

The invention provides a variable speed driving device. The variable speed driving device is characterized by comprising a driving part, a first kinematic pair and a second kinematic pair, when the driving piece rotates forwards, the first kinematic pair is driven to move at a first speed; and when the driving piece rotates reversely, the second kinematic pair is driven to move at a second speed. According to the variable speed driving device, a large high-low speed difference can be realized when the motor works at high power. The invention further provides an electronic lifting beauty instrument which comprises a body, a massage assembly and the variable speed driving device.

Description

technical field

[0001] The invention relates to a driving device, in particular to a variable-speed driving device capable of outputting different rotating speeds. Background technique

[0002] In order to output different speeds, traditional motors often change the drive current of the motor to make it work at different powers to achieve a large difference in high and low speeds. However, the motor has a problem of insufficient driving force at low speed, because if the duty cycle of the motor is adjusted to adjust the speed, it is easy to cause the motor to not have full power output, resulting in weak overall performance at low speed, and easy stalling and shutdown. Contents of the invention

[0003] The main technical problem to be solved by the present invention is to provide a variable-speed driving device, which can realize a large difference in high and low speeds even when the motor works at high power.

[0004] In order to solve the above technical problems, the...

Examples

Embodiment 1

[0032] refer to Figure 1-Figure 8 , the present invention also provides an electronic lifting beauty instrument, comprising: a body 1 , a massaging component 2 and a variable speed driving device 3 . The variable speed drive device 3 is used to output different rotational speeds to drive the movement frequency or movement speed of the massage assembly 2 .

[0033] The above-mentioned variable speed driving device 3 includes: a driving member 31, a first kinematic pair 32 and a second kinematic pair 33; when the driving member 31 rotates forward, it drives the first kinematic pair 32 to move at a first speed; When the driving member reverses, it drives the second kinematic pair 33 to move at the second speed. The first speed and the second speed are different. In this embodiment, the driving member 31 is respectively connected to the first kinematic pair 32 and the second kinematic pair 33 in one-way transmission, so that when the driving member 31 rotates forward or reverse...
