[0050] Embodiment 1

[0051] Reference Figures 1-7 The embodiment provides a cosmetic instrument, which comprises a shell 1, an electrode assembly and a lifting driving element 4.

[0052] The electrode assembly comprises a first electrode assembly 2 and a second electrode assembly 3, and the lifting driving element 4 is arranged in the shell 1 and used for driving the second electrode assembly 3 to move between a first position and a second position; when the second electrode assembly 3 is located at the first position, the second electrode assembly 3 and the first electrode head 21 and the second electrode head 31 of the first electrode assembly 2 are located in the same plane; when the second electrode assembly 3 is located at the second position, the second electrode head 31 of the second electrode assembly 3 is convex outwardly relative to the first electrode head 21 of the first electrode assembly 2. Thus, when the second electrode assembly 3 is located at the first position, the effective area of the electrode assembly capable of acting on the surface of human skin is S1, when the second electrode assembly 3 is located at the second position, the effective area of the electrode assembly capable of acting on the surface of human skin is S2; and S1>S2.

[0053] Thus, in the process of beautifying, the position of the second electrode assembly 3 can be selected according to the area to be beautified, so as to change the effective area of the electrode head. For example, when the forehead, cheeks and other areas with large skin area are beautified, the user can operate the second electrode assembly 3 to be in the first position, so that the effective area of the electrode head is the sum of the electrode head areas of the first electrode assembly 2 and the second electrode assembly 3. When the lips or eyes and other areas with small skin area are beautified, the user can operate the second electrode assembly 3 to be in the second position, so that the effective area of the electrode head is only the electrode head area of the second electrode assembly 3, which is convenient for operation in a small area.

[0054] It should be pointed out that in the embodiment, the second electrode head 31 protrudes outward and the first electrode head 21 protrudes outward. Alternatively, the second electrode head 31 can be recessed inward, and the first electrode head 21 can protrude outward. In this way, the area of the electrode head can also be reduced, which is convenient for operation in a small area. Therefore, as long as the relative movement of the electrode heads is achieved so that the two electrode heads are not in the same plane, the concept of the embodiment can be realized, which is a simple replacement of the embodiment. Meanwhile, in the embodiment, when the second electrode assembly 3 is in the first position, the first electrode head 21 and the second electrode head 31 are in the same plane. As a simple replacement, the two electrode heads can be located on an arc surface, or there can be a small height difference between the two electrode heads, which does not affect the joint action of the first electrode head 21 and the second electrode head 31 on the human skin. These are simple replacements of the embodiment.

[0055] In the embodiment, the second electrode assembly 3 has a lifting function, and the second electrode assembly 3 needs to have the basic function of the electrode assembly whether it is in the first position or the second position. Therefore, it must maintain electrical connection with the circuit board. Therefore, the second electrode assembly 3 comprises a second electrode head 31 and a lifting rod 32 fixedly connected with the second electrode head 31. The lifting rod 32 is provided with a conductive sheet 33 on both sides along the radial direction. One end of the conductive sheet 33 extends into the lifting rod 32 and is electrically connected with the second electrode head 31 provided at the end of the lifting rod 32.

[0056] The first electrode assembly 2 has a fixing seat 22 for mounting a first electrode head 21, the fixing seat 22 is provided with a displacement cavity 221 accommodating the second electrode assembly 3, the inner wall of the displacement cavity 221 has a contact 222 conductively connected with the conductive sheet 33; the fixing seat 22 is mounted with a circuit board 23 and the first electrode head 21; so the conductive sheet 33 can electrically connect the second electrode head 31 and the circuit board 23, and the conductive sheet 33 extends along the axial direction of the lifting rod 32, so that even if the second electrode head 31 moves relative to the contact 222, other positions on the conductive sheet 33 can still be electrically connected with the contact 222, ensuring the stability of the electrical connection of the second electrode head 31 during movement. In the embodiment, the first electrode head 21 and the second electrode head 31 can be radio frequency heads or micro-current positive and negative contacts 222, and the circuit board 23 can be provided with LED chips and corresponding driving circuits in addition to the circuits corresponding to the radio frequency heads or micro-current positive and negative contacts 222, so that the effect of light therapy can also be achieved.

[0057] In the embodiment, the lifting driving assembly relies on a motor to drive the lifting rod 32 to move, and specifically, the lifting driving member 4 includes a speed reduction motor 41 and a rotating sleeve 42; the speed reduction motor 41 is used to drive the rotating sleeve 42 to rotate, and the rotating sleeve 42 is connected with the lifting rod 32 through a reversing member; the lifting rod 32 is used to convert the rotation of the rotating sleeve 42 into the movement of the lifting rod 32 along the axial direction of the lifting rod 32.

[0058] In order to achieve the above-mentioned reversing effect, the rotating sleeve 42 is provided with a displacement passage 421 for the lifting rod 32 to pass through, and the reversing member includes a spiral guide rail 422 arranged on the inner wall of the displacement passage 421 and a guide block arranged on the lifting rod 32; the guide block is arranged in the spiral guide rail 422. In the embodiment, mounting holes are arranged on the two side walls of the lifting rod 32, and a cross rod 423 is arranged to pass through the mounting holes and expose the two ends outside the outer wall of the lifting rod 32 to form the guide block.

[0059] Embodiment 2

[0060] Reference Figures 8-10 The difference between the embodiment and the embodiment 1 is that a push rod motor 43 is used in the embodiment, so that the rotating sleeve in the embodiment 1 can be cancelled, and the lifting rod 32 is directly driven to move by the extension end 431 of the push rod motor 43.

[0061] Embodiment 3

[0062] Embodiments 1 and 2 are schemes of driving the lifting rod 32 by a motor, in order to simplify the structure and reduce the cost, in the embodiment, the lifting rod 32 is manually driven to lift.

[0063] For this purpose, reference Figures 11-13The lifting driving part 4 comprises a knob 44 and a rotating sleeve 42; the knob 44 is used to drive the rotating sleeve 42 to rotate; the rotating sleeve 42 is connected with the lifting rod 32 through a reversing part; the lifting rod 32 is used to convert the rotation of the rotating sleeve 42 into the movement of the lifting rod 32 along the axial direction of the lifting rod 32.

[0064] In order to realize the above-mentioned reversing effect, the rotating sleeve 42 is provided with a clearance passage 421 for the lifting rod 32 to pass through; the reversing part comprises a spiral guide rail 422 arranged on the inner wall of the clearance passage 421 and a guide block arranged on the lifting rod 32; the guide block is arranged in the spiral guide rail 422. In the embodiment, the two side walls of the lifting rod 32 are provided with mounting holes; a cross rod 423 passes through the mounting holes and the two ends of the cross rod 423 are exposed outside the outer wall of the lifting rod 32 to form the guide block.

[0065] In the embodiment, the knob 44 is arranged at the bottom of the shell 1 along the axial direction; the knob 44 is fixedly connected with the rotating sleeve 42 through a connecting rod 45. The user rotates the knob 44 to drive the rotating sleeve 42 to rotate through the connecting rod 45. The remaining parts are the same as those of the embodiment 1 and will not be described herein.

[0066] Embodiment 4

[0067] Reference Figures 14-16 The difference between the embodiment and the embodiment 3 is that the knob is arranged at the top of the shell 1 along the axial direction; the knob is insertedly fixed with the rotating sleeve 42. In this way, the fixed seat 22 of the first electrode assembly 2 can be used as the knob; the fixed seat 22 and the rotating sleeve 42 are inserted to realize the rotation of the fixed seat 22 to drive the rotating sleeve 42 to rotate. Through the arrangement of the fixed seat 22 as the knob 44, it is not necessary to additionally design a knob, and the structure is further simplified.

[0068] Embodiment 5

[0069] Reference Figures 17-19 The embodiments 3 and 4 are both the schemes of driving the knob to rotate by human power and then driving the lifting rod 32 to move through the reversing part. In the embodiment, the human power is directly used to drive the lifting rod 32 to move without the reversing.

[0070] Therefore, the lifting driving part 4 comprises a push button 46 fixedly connected with the lifting rod 32; the shell 1 is provided with a sliding groove 11 along the axial direction of the lifting rod 32 for the push button 46 to translate; one end of the push button 46 is fixedly connected with the lifting rod 32, and the other end is exposed outside the sliding groove 11 to form an operation end. The user only needs to push the operation end upward or downward to drive the lifting rod 32 to move upward or downward, so that the second electrode assembly 3 moves between the first position and the second position.

[0071] Embodiment 6

[0072] Reference Figures 20-22 The difference between embodiment 4 and embodiment 5 is that the up and down movement of the second electrode assembly 3 in embodiment 5 is dependent on the operation of the user. In embodiment 5, the up movement process of the second electrode assembly 3 is changed to be automatic, specifically: the lifting drive 4 comprises a resilient member 47 and a release member 48; when the second electrode assembly 3 is in the first position, the resilient member 47 is contracted along the axial direction of the lifting rod 32 in the energy storage state; the release member 48 is used to unlock the second electrode assembly 3 from the first position. In this way, the user only needs to unlock the second electrode assembly 3 from the first position through the release member 48, and the resilient member 47 will release the elastic restoring force to automatically drive the second electrode assembly 3 to rise.

[0074] In addition, the button 481 is also connected with a reset spring 483, when the button 481 is pressed, the reset spring 483 accumulates the elastic restoring force, so that when the user releases the button 481, the button 481 can automatically reset to the initial position.

[0075] The above is only the preferred specific embodiment of the present application, but the design concept of the present application is not limited to this, any skilled person in the art can make non-essential changes to the present application within the technical scope disclosed by the present application, which is an act of infringing the protection scope of the present application.
