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...
Embodiment 2
[0046] refer to Figure 9 , The difference between this embodiment and Embodiment 1 is that: in this embodiment, both kinematic pairs are gear kinematic pairs.
Embodiment 3
[0048] refer to Figure 10 , The difference between this embodiment and Embodiment 1 is that: in this embodiment, both kinematic pairs are belt kinematic pairs.
