Description

Technical Field

[0001] The present invention relates to the technical field of female facial grooming, and particularly to a biomedical beauty instrument for promoting the repair of beauty wounds. Background Art

[0002] A beauty instrument is a machine that adjusts and improves the body and face according to human physiological functions. In terms of functions, it has various functions such as freckle removal, wrinkle removal, and hair removal. In terms of names, it includes ultrasonic introduction, electronic freckle and nevus removal, and Galvanic nutrition introduction and export, etc.

[0003] Existing beauty instruments generally have the defect of single function. For example, they only have one of radio frequency technology, microcurrent technology, or infrared technology. Although they can achieve some effects, their functions also have certain limitations and are difficult to meet people's skin care needs, resulting in people being unable to obtain satisfactory beauty effects. Therefore, a beauty instrument with the publication number of CN118340996A is disclosed, which includes a housing. One end of the housing forms a light-transmitting part, and a light-emitting component. The light-emitting component includes at least two light-emitting devices spaced in the housing. Each light-emitting device includes a base, a first light-emitting wick, and a second light-emitting wick. The first light-emitting wick and the second light-emitting wick are both installed on the base. The first light-emitting wick is used to emit red light towards the light-transmitting part, and the second light-emitting wick is used to emit infrared light towards the light-transmitting part.

[0004] The above beauty instrument is provided with a first light-emitting wick for emitting red light towards the light-transmitting part of the housing. When irradiating the skin, it can promote the regeneration of fibroblast cells, induce the synthesis of new collagen, and reduce the production of matrix metalloproteinases, achieving the purpose of delaying skin aging. The second light-emitting wick is provided for emitting infrared light towards the light-transmitting part of the housing. When irradiating the skin, it can promote the transformation of fibroblasts into myofibroblasts, thereby promoting the regeneration of collagen and elastin, smoothing fine lines, reducing wrinkles, and making the skin firm and smooth.

[0005] However, both the above beauty instrument and existing beauty instruments use buttons to adjust the gears. When in use, the operator holds the beauty instrument for contouring, and the fingers are very likely to accidentally touch the buttons, causing the gear to change, thereby reducing the comfort during beauty treatment and affecting the beauty experience. In addition, different gears are suitable for different contouring. If the wrong gear is used, it will seriously cause contouring contusions.

[0006] Therefore, a new biomedical beauty instrument for promoting the repair of beauty wounds can be adopted to solve the deficiencies of the prior art. Summary of the Invention

[0007] The object of the present invention is to solve the problems of reduced contouring comfort and contouring contusion caused by accidental gear touch in the prior art, and to propose a biomedical beauty instrument for promoting the repair of beauty wounds.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] A biomedical beauty instrument for promoting the repair of beauty wounds, including a housing, a beauty head fixedly installed on the housing, and a plurality of control buttons, and further including a main board fixedly installed inside the housing;

[0010] A control unit matched with the control buttons is installed on the main board. The control unit includes a control outer box fixedly installed on the main board. A cover body is fixedly installed on the control outer box, and a plurality of control modules matched with the corresponding control buttons are fixedly installed inside the control outer box;

[0011] The control module is composed of a connection motor group and a conduction motor group. The connection motor group is connected to the main board, and the conduction motor group is used to connect the connection motor group to form an electrical circuit loop between the connection motor group and the main board for power on.

[0012] Preferably, the connection motor group includes a conductive seat fixedly installed inside the control outer box. Two conductive columns are fixedly installed inside the conductive seat. A conductive connecting rod is fixedly installed on each of the two conductive columns. A first spring rod is fixedly installed on each of the two conductive connecting rods. A first conductive block is fixedly installed at one end of each of the two first spring rods away from the corresponding conductive connecting rod. A lower card seat is fixedly installed on the conductive seat.

[0013] Preferably, the conduction motor group includes an upper card seat fixedly connected to the lower card seat by clamping. A pressing column is slidably installed on the upper card seat. A plurality of second spring rods are installed between the pressing column and the upper card seat. A support column is fixedly installed on the pressing column. A fixed disk is fixedly installed on the support column. A conductive plate matched with the two first conductive blocks is rotatably installed on the fixed disk. A horizontal control mechanism matched with the conductive plate is installed on the support column, and a vertical control mechanism is installed inside the conductive plate.

[0014] Preferably, a convex block is fixedly installed on the pressing column, and the pressing column and the upper card seat are locked and limited by a locking threaded sleeve.

[0015] Preferably, the horizontal control mechanism includes a fixed sleeve fixedly installed on the support column. Two sliding plates are slidably installed on the fixed sleeve. A spiral sleeve is fixedly installed on the two sliding plates together. A plurality of counterweight pieces are fixedly installed on each of the two sliding plates. A spiral rod matched with the spiral sleeve is fixedly installed on the conductive plate.

[0016] Preferably, the vertical control mechanism includes two second elastic telescopic rods rotatably installed inside the conductive plate. A shaft body is fixedly installed at the telescopic end of each of the two second elastic telescopic rods. A second conductive block cooperating with the corresponding first conductive block is rotatably installed on each of the two shaft bodies. A rotating structure cooperating with the two second elastic telescopic rods is installed on the conductive plate, and a limiting structure cooperating with the two shaft bodies is installed on the conductive plate.

[0017] Preferably, the rotating structure includes a limiting frame fixedly installed inside the conductive plate. A slider is slidably installed on the limiting frame. A shaft rod is rotatably installed on the slider. Two connecting rods are rotatably installed on the shaft rod. One end of each of the two connecting rods away from the shaft rod is rotatably connected to one end of the corresponding second elastic telescopic rod. A counterweight block is fixedly installed on the slider. A third spring rod is installed between the slider and the limiting frame.

[0018] Preferably, two rotating columns are rotatably installed on the counterweight block. Two groove bodies for the corresponding rotating columns to slide are formed on the conductive plate.

[0019] Preferably, the limiting structure includes two first elastic telescopic rods rotatably installed on the conductive plate. The telescopic ends of the two first elastic telescopic rods are rotatably connected to the corresponding shaft bodies. An arc-shaped reset spring is fixedly installed between the two first elastic telescopic rods.

[0020] Preferably, an arc-shaped limiting baffle cooperating with the reset spring is slidably installed on the conductive plate. A tension spring is fixedly installed between the limiting baffle and the conductive plate.

[0021] Compared with the existing technology, the advantages of the present invention are as follows:

[0022] 1. When the present beauty instrument is used for beauty wound repair, by setting the counterweight piece, sliding plate, spiral sleeve and spiral rod, when the beauty instrument is horizontally placed with the front side facing up, the conductive plate is flush with the two first conductive blocks. Pressing the pressing column can make the conductive plate abut against the first conductive block, so that the circuit is connected. When the beauty instrument is horizontally placed with the back side facing up, at this time, beauty operations are carried out, and the conductive plate and the two first conductive blocks are staggered. Pressing the pressing column will not make the conductive plate communicate with the two first conductive blocks. Even if the button is accidentally touched, the gear position will not be adjusted, which can effectively avoid the situation of gear position change caused by accidental touch and has higher safety.

[0023] 2. When this beauty instrument is used for repairing beauty wounds, by setting a counterweight and a connecting rod, the second conductive block can be driven to extend from the conductive plate when the beauty instrument is vertical. At this time, regardless of whether the conductive plate is flush with or staggered from the first conductive block, the second conductive block in the conductive plate will extend. When the conductive plate is flush with the first conductive block, the circuit is connected through the conductive plate. When the conductive plate is staggered from the first conductive block, the circuit is connected through the second conductive block. In this way, the gear adjustment can be carried out when the beauty instrument is vertical. The vertical state is for manual and conscious adjustment by the operator, so the situation of incorrect gear adjustment can be avoided.

[0024] 3. When this beauty instrument is used for repairing beauty wounds, by setting the first elastic telescopic rod to limit the second conductive block, the second conductive block can be kept moving horizontally, and at the same time, the position of the second conductive block can be controlled to avoid dislocation between the second conductive block and the first conductive block, ensuring that the second conductive block can be aligned with the first conductive block and ensuring the connection of the circuit.

[0025] In summary, when this invention is used for repairing beauty wounds, the gear adjustment cannot be carried out during the beauty process. The gear adjustment can only be carried out when the control button is within the sight of the operator, which can effectively avoid the situation of incorrect gear adjustment caused by accidental touch, resulting in reduced comfort or even bruising, and has higher safety performance.

Specific implementation mode

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1: Refer to Figures 1 - 3 , a biomedical beauty instrument for promoting the repair of beauty wounds, including a housing 1, a beauty head 3 fixedly installed on the housing 1, and a plurality of control buttons 2, and further including a main board 4 fixedly installed inside the housing 1.

[0046] A heat dissipation fan 6 is installed on the main board 4. When the main board 4 operates, the main board 4 is dissipated heat through the heat dissipation fan 6;

[0047] Since the transmission between the beauty head 3 and the main board 4 is an existing one, the specific structure and operation principle of the beauty head 3 will not be elaborated in detail here.

[0048] Embodiment 2: The difference between this embodiment and the technical solution of Embodiment 1 lies in: Refer to Figures 4 - 16 , a control unit 5 cooperating with the control buttons 2 is installed on the main board 4. The control unit 5 includes a control outer box 9 fixedly installed on the main board 4, a cover body 7 is fixedly installed on the control outer box 9, and a plurality of control modules 8 cooperating with the corresponding control buttons 2 are fixedly installed inside the control outer box 9;

[0049] The control outer box 9 is made of a non-metallic material and has better insulation. A hole communicating with the main board 4 is opened at the bottom of the control outer box 9, and the control module 8 is connected to the main board 4 through the hole, which can effectively avoid the mutual influence of the control modules 8 and generate an electric field, thereby improving safety.

[0050] The control module 8 is composed of a connection motor group and a conduction motor group, and the connection motor group is connected to the main board 4;

[0051] The connection motor group includes a conductive seat 10 fixedly installed inside the control outer box 9. Two conductive columns 16 are fixedly installed inside the conductive seat 10. A conductive connecting rod 18 is fixedly installed on each of the two conductive columns 16. A first spring rod 17 is fixedly installed on each of the two conductive connecting rods 18. A first conductive block 15 is fixedly installed at one end of each of the two first spring rods 17 away from the corresponding conductive connecting rod 18. A lower card seat 13 is fixedly installed on the conductive seat 10;

[0052] Two conductive posts 16 on the conductive base 10 are respectively connected to the corresponding connectors on the main board 4. When bridging and pulling between the two first conductive blocks 15, a loop closed circuit will be formed among the first conductive blocks 15, the bridge, and the two conductive posts 16, which can trigger the control system on the main board 4 to adjust the gear position.

[0053] Since the bridge (the bridge here is explained below) will press the first conductive block 15, a first spring rod 17 is designed here to buffer the first conductive block 15, avoiding hard collision between the bridge and the first conductive block 15, which can effectively reduce the wear of the first conductive block 15 and the bridge, and reduce the probability of poor contact.

[0054] The conductive unit is used to connect the connection unit, so that a circuit loop is formed between the connection unit and the main board 4 for power-on;

[0055] The conductive unit includes an upper card seat 12 fixedly connected to the lower card seat 13 by clamping. A pressing column 14 is slidably installed on the upper card seat 12, and a plurality of second spring rods 19 are installed between the pressing column 14 and the upper card seat 12. A support column 27 is fixedly installed on the pressing column 14, a fixed disk 21 is fixedly installed on the support column 27, and a conductive plate 26 cooperating with the two first conductive blocks 15 is rotatably installed on the fixed disk 21. A horizontal control mechanism cooperating with the conductive plate 26 is installed on the support column 27;

[0056] When installing the conductive unit, the upper card seat 12 can be snapped into the lower card seat 13 to complete the connection between the conductive unit and the connection unit;

[0057] Pressing the control button 2 will drive the pressing column 14 to slide in the upper card seat 12. The movement of the pressing column 14 drives the support column 27 to move, thereby driving the fixed disk 21 to move. The movement of the fixed disk 21 drives the conductive plate 26 to move (the conductive plate 26 here is the bridge mentioned above). The movement of the conductive plate 26 will abut against the two first conductive blocks 15, connecting the two first conductive blocks 15 and closing the circuit. When the control button 2 is released, the pressing column 14 will reset under the action of the second spring rod 19. At this time, the conductive plate 26 is separated from the first conductive block 15, and the circuit is disconnected.

[0058] A convex block is fixedly installed on the pressing column 14. The pressing column 14 and the upper card seat 12 are locked and limited by a locking threaded sleeve 11. Rotating the locking threaded sleeve 11 will drive the pressing column 14 to move, so as to change the initial positions of the pressing column 14 and the fixed disk 21. In this way, the pressing stroke size can be changed to adjust the pressing sensitivity. The closer the pressing column 14 is to the first conductive block 15, the smaller the pressing stroke and the higher the pressing sensitivity;

[0059] The horizontal control mechanism includes a fixed sleeve 20 fixedly installed on the support column 27. Two sliding plates 24 are slidably installed on the fixed sleeve 20. A spiral sleeve 23 is fixedly installed on the two sliding plates 24 together. And a plurality of counterweight pieces 25 are fixedly installed on the two sliding plates 24. A screw rod 22 matched with the spiral sleeve 23 is fixedly installed on the conductive plate 26;

[0060] A groove is formed on the side of the fixed sleeve 20 for cooperating with the first conductive block 15 and allowing the first conductive block 15 to pass through, so as to avoid the first conductive block 15 and the conductive connecting rod 18 from hindering the downward movement of the fixed sleeve 20, ensuring that the conductive plate 26 or the second conductive block 28 can smoothly touch the first conductive block 15.

[0061] When the beauty instrument is facing downwards, at this time, under the action of gravity, the counterweight piece 25 will drive the sliding plate 24 to move towards the side away from the conductive plate 26. Since the sliding plate 24 slides on the fixed sleeve 20, the sliding plate 24 cannot rotate. Therefore, when the sliding plate 24 moves, it will drive the spiral sleeve 23 to move. The movement of the spiral sleeve 23 will drive the screw rod 22 to rotate. The rotation of the screw rod 22 drives the conductive plate 26 to rotate, thereby changing the angle of the conductive plate 26. By setting the pitch of the screw rod 22, it is possible to easily control the number of turns of the screw rod 22 when the spiral sleeve 23 moves to the end of the screw rod 22, so as to control the final position of the rotation of the conductive plate 26, making the conductive plate 26 misaligned with the two first conductive blocks 15. At this time, no matter how the pressing column 14 is pressed, the conductive plate 26 will move between the two first conductive blocks 15 and will not contact the two first conductive blocks 15, and a closed-loop circuit cannot be formed, so the gear adjustment cannot be controlled;

[0062] When the beauty instrument is facing upwards, at this time, under the action of gravity, the counterweight piece 25 will drive the sliding plate 24 to move towards the side close to the conductive plate 26. When the sliding plate 24 moves, it will drive the spiral sleeve 23 to move. The movement of the spiral sleeve 23 will drive the screw rod 22 to rotate. The rotation of the screw rod 22 drives the conductive plate 26 to rotate, thereby resetting the conductive plate 26. After resetting, the conductive plate 26 is flush with the two first conductive blocks 15. When the pressing column 14 is pressed, the conductive plate 26 will contact the two first conductive blocks 15 at the same time, forming a closed-loop circuit, and at this time, the gear can be freely adjusted.

[0063] A vertical control mechanism is installed inside the conductive plate 26;

[0064] The vertical control mechanism includes two second elastic telescopic rods 30 rotatably installed inside the conductive plate 26. A shaft body is fixedly installed at the telescopic end of each of the two second elastic telescopic rods 30. A second conductive block 28 matched with the corresponding first conductive block 15 is rotatably installed on each of the two shaft bodies. A rotating structure matched with the two second elastic telescopic rods 30 is installed on the conductive plate 26;

[0065] Due to the problem of the usage scenario, if the adjustment gear can only be facing upwards during adjustment, there are certain limitations in such usage. Therefore, a vertical control mechanism is designed to adjust the gear in another scenario. At this time, the beauty device needs to be erected, maintaining an angle greater than 45 degrees with the vertical direction. The second elastic telescopic rod 30 will rotate under the action of the rotating structure, and the second conductive block 28 will extend out of the conductive plate 26. At this time, the conductive plate 26 and the two second conductive blocks 28 are staggered. And the conductive plate 26 and the two first conductive blocks 15 are either staggered or flush. When the conductive plate 26 is flush with the first conductive block 15, when the pressing column 14 moves, it will make the conductive plate 26 contact and conduct electricity with the two first conductive blocks 15. When the conductive plate 26 is misaligned with the two first conductive blocks 15, at this time, the second conductive block 28 will contact the corresponding first conductive block 15, and a closed-loop circuit will also be formed at this time.

[0066] The rotating structure includes a limiting frame 31 fixedly installed inside the conductive plate 26. A slider is slidably installed on the limiting frame 31. A shaft rod is rotatably installed on the slider. Two connecting rods 36 are rotatably installed on the shaft rod. The ends of the two connecting rods 36 away from the shaft rod are rotatably connected to one end of the corresponding second elastic telescopic rod 30. A counterweight 32 is fixedly installed on the slider. A third spring rod 35 is installed between the slider and the limiting frame 31;

[0067] After the beauty device is erected, the counterweight 32 will drive the slider to move inside the limiting frame 31 under the action of gravity, thereby driving one end of the two connecting rods 36 to move. The movement of the two connecting rods 36 will drive the end of the second elastic telescopic rod 30 connected to the corresponding connecting rod 36 to move downward. Since the second elastic telescopic rod 30 rotates around a fulcrum of the conductive plate 26, the end of the second elastic telescopic rod 30 connected to the connecting rod 36 not only moves downward along with the connecting rod 36 but also rotates around the fulcrum. Therefore, as the counterweight 32 moves downward, the included angle between the two connecting rods 36 decreases;

[0068] As the second elastic telescopic rod 30 rotates, the second conductive block 28 at the end of the second elastic telescopic rod 30 will extend out of the conductive plate 26.

[0069] Two rotating columns are rotatably installed on the counterweight 32. Two groove bodies for the corresponding rotating columns to slide are opened on the conductive plate 26;

[0070] Since the counterweight 32 is fixedly connected to the slider, and the slider moves in the limit frame 31, once the counterweight 32 is tilted, the pressure between the slider and the limit frame 31 will increase, thereby increasing the friction, which will affect the movement of the slider and make it impossible for the slider to slide and respond in time. A larger tilt angle is required to move the counterweight 32. The rotating column and the slot body are provided to distribute the pressure when the counterweight 32 is tilted, reduce the friction between the slider and the limit frame 31, and thus enable the counterweight 32 to move at a smaller tilt angle (the movement of the counterweight 32 needs to overcome the friction between the slider and the limit frame 31 and the elastic force of the third spring rod 35). The weight of the counterweight 32 can be set to control the minimum vertical angle of the beauty instrument required when the second conductive block 28 moves to align with the first conductive block 15. The heavier the counterweight 32, the smaller the angle required to vertically move the beauty instrument.

[0071] A limiting structure matching the two shafts is installed on the conductive plate 26;

[0072] The limiting structure includes two first elastic telescopic rods 29 rotatably mounted on the conductive plate 26 , the telescopic ends of the two first elastic telescopic rods 29 are rotatably connected to the corresponding shafts, and an arc-shaped return spring 34 is fixedly mounted between the two first elastic telescopic rods 29 .

[0073] As the second elastic telescopic rod 30 rotates, the first elastic telescopic rod 29 will be driven to rotate. At this time, the rotation fulcrum on the first elastic telescopic rod 29, the rotation fulcrum on the second elastic telescopic rod 30 and the second conductive block 28 form an isosceles triangle system. Therefore, as the first elastic telescopic rod 29 and the second elastic telescopic rod 30 rotate, the angle between the first elastic telescopic rod 29 and the second elastic telescopic rod 30 changes, so that the lengths of the first elastic telescopic rod 29 and the second elastic telescopic rod 30 change. The changes in the first elastic telescopic rod 29 and the second elastic telescopic rod 30 are the same, so the second conductive block 28 moves in a direction perpendicular to the side of the conductive plate 26 to ensure that the second conductive block 28 is precisely aligned with the first conductive block 15 after moving out of the conductive plate 26.

[0074] As the angle between the two first elastic telescopic rods 29 increases, the elastic force of the reset spring 34 increases. At this time, the movement of the counterweight block 32 needs to overcome the elastic force of the reset spring 34. When the beauty instrument is horizontal, the gravity of the counterweight block 32 is perpendicular to the conductive plate 26 and will not drive the connecting rod 36 to move. At this time, it is reset under the action of the third spring rod 35 and the reset spring 34, and the second conductive block 28 is retracted into the conductive plate 26.

[0075] An arc-shaped limit baffle 33 cooperating with a return spring 34 is slidably mounted on the conductive plate 26, and a tension spring is fixedly mounted between the limit baffle 33 and the conductive plate 26;

[0076] Due to the change (decrease in angle) between the two first elastic telescopic rods 29, the return spring 34 is compressed. At this time, the arc-shaped limit baffle 33 limits the return spring 34 to prevent the return spring 34 from deforming, so that the return spring 34 always maintains an arc shape;

[0077] Since the pivots of the two first elastic telescopic rods 29 are different, as the angle between the two first elastic telescopic rods 29 changes, the return spring 34 needs to change its arc according to the included angle, which can ensure the elastic performance of the return spring 34. If the two first elastic telescopic rods 29 rotate coaxially, there is no need to change the arc of the return spring 34.

[0078] The specific operation steps of this device are as follows:

[0079] During beauty treatment, with the beauty instrument facing downwards, the counterweight 25 will drive the sliding plate 24 to move away from the conductive plate 26 under the action of gravity. Since the sliding plate 24 slides on the fixed sleeve 20, the sliding plate 24 cannot rotate. Therefore, when the sliding plate 24 moves, it will drive the spiral sleeve 23 to move. The movement of the spiral sleeve 23 will drive the spiral rod 22 to rotate, and the rotation of the spiral rod 22 will drive the conductive plate 26 to rotate, thereby changing the angle of the conductive plate 26. By setting the pitch of the spiral rod 22, it is easy to control the number of turns of the spiral rod 22 when the spiral sleeve 23 moves to the end of the spiral rod 22, so as to control the final position of the rotation of the conductive plate 26, making the conductive plate 26 misaligned with the two first conductive blocks 15. At this time, no matter how the pressing column 14 is pressed, the conductive plate 26 will move between the two first conductive blocks 15 and will not contact the two first conductive blocks 15, so a closed-loop circuit cannot be formed, and the gear adjustment cannot be controlled;

[0080] When the gear needs to be adjusted, one method is to turn the beauty instrument face upwards: when the beauty instrument is face upwards, the counterweight 25 will drive the sliding plate 24 to move towards the conductive plate 26 under the action of gravity. When the sliding plate 24 moves, it will drive the spiral sleeve 23 to move. The movement of the spiral sleeve 23 will drive the spiral rod 22 to rotate, and the rotation of the spiral rod 22 will drive the conductive plate 26 to rotate, so that the conductive plate 26 is reset. After resetting, the conductive plate 26 is flush with the two first conductive blocks 15. Press the pressing column 14, and the conductive plate 26 will contact the two first conductive blocks 15 at the same time, forming a closed-loop circuit. At this time, the gear can be freely adjusted;

[0081] Another method for adjusting the gear position: Stand the beauty device upright and keep an angle greater than 45 degrees with the vertical direction. Under the action of gravity, the counterweight 32 will drive the slider to move within the limit frame 31, thereby driving one end of the two connecting rods 36 to move. The movement of the two connecting rods 36 will drive the end of the second elastic telescopic rod 30 connected to the corresponding connecting rod 36 to move downward. Since the second elastic telescopic rod 30 rotates around a fulcrum of the conductive plate 26, the end of the second elastic telescopic rod 30 connected to the connecting rod 36 not only moves downward along with the connecting rod 36 but also rotates around the fulcrum. Therefore, as the counterweight 32 moves downward, the angle between the two connecting rods 36 decreases;

[0082] The rotation of the second elastic telescopic rod 30 extends the second conductive block 28 out of the conductive plate 26. At this time, the conductive plate 26 and the two second conductive blocks 28 are staggered. And the conductive plate 26 and the two first conductive blocks 15 are either staggered or flush. When the conductive plate 26 is flush with the first conductive block 15, pressing the column 14 to move will cause the conductive plate 26 to contact and conduct electricity with the two first conductive blocks 15. When the conductive plate 26 is misaligned with the two first conductive blocks 15, the second conductive block 28 will contact the corresponding first conductive block 15, and a closed-loop circuit will also be formed at this time;

[0083] When performing beauty wound repair, it is impossible to adjust the gear position during the beauty process. The gear position can only be adjusted when the control button 2 is within the line of sight of the operator, which can effectively avoid the situation of accidental gear adjustment causing a decrease in comfort or even bruising, and has higher safety performance.

[0084] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
