[0002] With the development of the beauty industry, microneedling beauty devices have gained widespread attention because they can effectively promote the penetration of beauty serums and improve skin texture. Microneedling beauty devices create microchannels on the skin surface through microneedles, thereby achieving effects such as improving skin texture, reducing fine lines, and removing acne scars.

[0003] Existing microneedling devices often suffer from inconvenient installation and removal of microneedles, requiring complex fixing structures or additional tools, resulting in low replacement efficiency and hygiene difficulties. Furthermore, continuous and precise depth control of the microneedles is challenging, failing to meet the diverse needs of different skin areas and types. Secondly, the reciprocating drive structure of the microneedles often lacks stability, leading to uneven insertion force and affecting both aesthetic results and safety. Therefore, there is an urgent need for an electrically controlled microneedle delivery device that enables rapid assembly and disassembly of the microneedle array, continuous and precise adjustment of insertion depth, structural stability, and comfortable operation, overcoming the shortcomings of existing technologies.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-6 This invention provides a technical solution: an electro-controlled microneedle infusion beauty device, comprising: Main housing 1, the main housing 1 includes a working cover 101 and a handle 102; Microneedle assembly 2 includes multiple microneedle arrays and a connecting housing 201 that carries the microneedle arrays. The connecting housing 201 is slidably connected to the inside of the working cover 101, and the bottom surface of the connecting housing 201 extends to the bottom of the working cover 101. The microneedle assembly 2 is used for quick installation and removal of microneedle modules. The depth adjustment component 3 is connected to the main body housing 1 and is connected to the microneedle assembly 2. The depth adjustment component 3 is used to drive the connecting housing 201 to reciprocate relative to the working cover 101 so as to drive the microneedle array to periodically pierce the skin surface. The depth adjustment component 3 can continuously change the maximum piercing depth of the microneedle array as needed.

[0020] When this electronically controlled microneedle induction beauty device is in operation, the microneedle array is first inserted into the limiting groove 208. The mounting frame 202 is then slid by the drive cylinder 203, causing the locking block 204 to engage with the locking groove 207 of the microneedle array mounting base 205, thus completing the rapid installation of the sterilized microneedle array. The user rotates the adjustment knob 317, which, through the transmission wheel, transmission belt 316, gear rack, and other transmission structures, drives the ellipsoidal block 302 to rotate, changing its contact position with the transmission roller 305, thereby continuously adjusting the maximum insertion depth of the microneedles. After pressing the switch button 321, the drive motor 318 drives the crossbar 303 to rotate via the bevel gear transmission belt 316, which in turn drives the double-headed telescopic rod 301 and the ellipsoidal block 302 to rotate. The ellipsoidal block 302 pushes the transmission roller 305 and the connecting housing 201 to move vertically back and forth, so that the microneedle array can be periodically inserted into the skin. The transmission spring 307 provides a restoring force to ensure smooth movement. When disassembling, pressing the unlock button 209 will cause the drive cylinder 203 to move in the opposite direction, so that the locking block 204 can be disengaged from the locking groove 207, and the microneedle array can be removed.

[0021] Please see Figure 1-4 The working cover 101 is fixedly connected to the bottom surface of the handle 102, and the inside of the working cover 101 is connected to the inside of the handle 102.

[0022] The microneedle assembly 2 includes a connecting housing 201, a mounting frame 202, a driving cylinder 203, and a locking block 204. The mounting frame 202 is slidably connected inside the connecting housing 201. The mounting frame 202 has multiple sets of horizontally evenly distributed crossbars inside. Multiple sets of driving cylinders 203 are provided. The driving cylinders 203 are fixedly connected to the inner side wall of the connecting housing 201. The front end of the piston rod of the driving cylinder 203 is fixedly connected to the side of the mounting frame 202. Multiple sets of locking blocks 204 are fixedly connected to one side of the inner wall of the mounting frame 202 and one side of the horizontal bar on the mounting frame 202.

[0023] The microneedle assembly 2 also includes a microneedle array, which includes a mounting base 205 and a guide microneedle 206. The mounting base 205 is provided with multiple sets, and multiple sets of snap-fit ​​slots 207 are opened on the mounting base 205. The snap-fit ​​slots 207 are matched with the size and position of the snap-fit ​​block 204. Multiple sets of guide microneedles 206 are evenly arranged and fixedly connected to the bottom surface of the mounting base 205.

[0024] The bottom surface of the connecting housing 201 has multiple sets of evenly distributed limiting grooves 208, the size of which matches the size of the microneedle array.

[0025] An unlocking button 209 is fixedly connected to the side of the connecting housing 201, and the unlocking button 209 is electrically connected to the driving cylinder 203.

[0026] In use, the user aligns the mounting base 205 of the microneedle array with the limiting groove 208 on the bottom surface of the connecting housing 201, allowing the mounting base 205 to enter the limiting groove 208 for initial positioning. At this time, the snap-fit ​​groove 207 on the mounting base 205 is aligned with the snap-fit ​​block 204 on the inner side of the mounting frame 202. Pressing the unlock button 209 activates the drive cylinder 203, whose piston rod pushes the mounting frame 202 to slide horizontally along the inside of the connecting housing 201. As the mounting frame 202 slides, the snap-fit ​​block 204 gradually inserts into the snap-fit ​​groove 207, achieving snap-fit ​​fixation of the microneedle array. Because snap-fit ​​blocks 204 are provided on both inner walls and the crossbar of the mounting frame 202, and the limiting groove 208 restricts the position of the microneedle array, the microneedle array is constrained in both the horizontal and vertical directions, ensuring stable installation. If the microneedle 206 needs to be replaced, press the unlock button 209 again to retract the piston rod of the drive cylinder 203, and the microneedle array can be removed. Through the above steps, the microneedle array is quickly, accurately, and securely installed on the connecting housing 201, providing a stable foundation for subsequent insertion operations.

[0027] Please see Figure 1 , Figure 5 and Figure 6 The depth adjustment component 3 includes a double-headed telescopic rod 301, an ellipsoidal block 302, and a connecting crossbar 303. One piston rod end of the double-headed telescopic rod 301 is rotatably connected to the inner wall of the working cover 101, and the other piston rod end of the double-headed telescopic rod 301 is fixedly connected to the connecting crossbar 303. The other end of the connecting crossbar 303 is rotatably connected to the inner wall of the working cover 101. The central axis of the ellipsoidal block is set in the horizontal direction. The ellipsoidal block 302 is fixedly connected to the cylinder of the double-headed telescopic rod 301. The ellipsoidal block 302 has a first surface and a second surface arranged coaxially and parallel to each other. Both the first surface and the second surface are elliptical. From the first surface to the second surface, the elliptical cross-section of the ellipsoidal block 302 only increases in size in the direction of the major axis, and remains unchanged in the direction of the minor axis.

[0028] The depth adjustment assembly 3 also includes a connecting seat 304, a transmission roller 305, a mounting plate 306, and a transmission spring 307. The connecting seat 304 is fixedly connected to the top surface of the connecting housing 201. The transmission roller 305 is rotatably connected to the connecting seat 304 and abuts against the peripheral side surface of the ellipsoidal block 302. Multiple sets of mounting plates 306 are provided and are fixedly connected to the inner wall of the working cover 101. One end of the transmission spring 307 is fixedly connected to the bottom surface of the mounting plate 306, and the other end of the transmission spring 307 is fixedly connected to the top surface of the connecting housing 201.

[0029] The depth adjustment assembly 3 also includes a connecting sleeve 308, a connecting vertical rod 309, a transmission rack 310, a transmission gear 311, a first horizontal rod 312, a second horizontal rod 313, a first transmission wheel 314, a second transmission wheel 315, a transmission belt 316, and an adjustment knob 317. The connecting sleeve 308 is rotatably connected to the cylinder of the double-headed telescopic rod 301. The connecting vertical rod 309 is fixedly connected to the connecting sleeve 308. The transmission rack 310 is fixedly connected to the upper end of the connecting vertical rod 309. The first horizontal rod 312 and the second horizontal rod 313 are also connected. A crossbar 313 is rotatably connected to the inner wall of the handle 102. A first crossbar 312 is located below the second crossbar 313. A first transmission wheel 314 and a transmission gear 311 are fixedly connected to the first crossbar 312. The transmission gear 311 meshes with the transmission rack 310. A second transmission wheel 315 is fixedly connected to the second crossbar 313. A transmission belt 316 drives the first transmission wheel 314 and the second transmission wheel 315. One end of the second crossbar 313 passes through the handle 102 and is fixedly connected to the adjustment knob 317.

[0030] The depth adjustment assembly 3 also includes a drive motor 318, a first bevel gear 319, a second bevel gear 320, and a switch button 321. The drive motor 318 is fixedly connected to the inner side wall of the working cover 101. The first bevel gear 319 is fixedly connected to the output shaft of the drive motor 318. The second bevel gear 320 is fixedly connected to the connecting crossbar 303. The first bevel gear 319 and the second bevel gear 320 mesh with each other. The switch button 321 is fixedly connected to the surface of the handle 102 and is electrically connected to the drive motor 318.

[0031] The core of the depth adjustment component 3 is the eccentric structure of the ellipsoidal block 302 and the contact transmission with the transmission roller 305. By changing the contact position between the ellipsoidal block 302 and the transmission roller 305, the maximum insertion depth of the microneedle can be continuously adjusted. The user rotates the adjustment knob 317. The adjustment knob 317 drives the second horizontal bar 313 to rotate, which in turn drives the second transmission wheel 315 to rotate. The second transmission wheel 315 drives the first transmission wheel 314 to rotate via the transmission belt 316. The first transmission wheel 314 drives the first horizontal bar 312 to rotate, which in turn drives the transmission gear 311 fixed on the first horizontal bar 312 to rotate. The transmission gear 311 meshes with the transmission rack 310, so the rotation of the transmission gear 311 drives the transmission rack 310 to move left and right. The transmission rack 310 drives the connecting vertical rod 309 to move, and the connecting vertical rod 309 drives the connecting sleeve 308 to move left and right around the cylinder of the double-headed telescopic rod 301. The movement of the connecting sleeve 308 causes the ellipsoidal block 302 to move synchronously, changing the contact position between the ellipsoidal block 302 and the transmission roller 305. Since the cross-section of the ellipsoidal block 302 is elliptical, and its major axis gradually increases while its minor axis remains constant from the first surface to the second surface, when the contact position is at the point where the major axis is smaller, the pushing force on the transmission roller 305 is smaller, resulting in a smaller maximum penetration depth of the microneedles. When the contact position is at the point where the major axis is larger, the pushing force on the transmission roller 305 is larger, the initial position of the connecting housing 201 is lower, and the maximum penetration depth of the microneedles is larger. By continuously changing the contact position, the maximum penetration depth of the microneedle array can be continuously adjusted.

[0032] When the device is needed, the user presses the switch button 321, and the drive motor 318 starts. The output shaft of the drive motor 318 drives the first bevel gear 319 to rotate. The first bevel gear 319 meshes with the second bevel gear 320, driving the second bevel gear 320 to rotate. The second bevel gear 320 is fixed on the connecting crossbar 303, so the connecting crossbar 303 rotates synchronously with the second bevel gear 320. One end of the connecting crossbar 303 is rotatably connected to the inner wall of the working cover 101, and the other end is fixedly connected to the piston rod of the double-headed telescopic rod 301, so the rotation of the connecting crossbar 303 drives the double-headed telescopic rod 301 to rotate. The rotation of the double-headed telescopic rod 301 drives the ellipsoidal block 302 on its cylinder to rotate synchronously. During the rotation, the ellipsoidal block 302 periodically pushes the transmission roller 305 up and down. The transmission roller 305 drives the connecting housing 201 to reciprocate along the vertical direction inside the working cover 101 through the connecting seat 304. The reciprocating movement of the connecting housing 201 drives the microneedle array to perform periodic insertion and withdrawal actions.

[0033] The implementation principle of the electro-controlled microneedle induction beauty device in this application embodiment is as follows: When the electro-controlled microneedle induction beauty device is working, the microneedle array is first inserted into the limiting groove 208. The mounting frame 202 is driven to slide by the driving cylinder 203, so that the snap-fit ​​block 204 cooperates with the snap-fit ​​groove 207 of the microneedle array mounting seat 205, completing the rapid installation of the sterilized microneedle array. The user rotates the adjustment knob 317, which drives the ellipsoidal block 302 to rotate through the transmission structure such as the transmission wheel, transmission belt 316, gear and rack, etc., changing its contact position with the transmission roller 305, thereby continuously... Adjust the maximum insertion depth of the microneedles; after pressing the switch button 321, the drive motor 318 drives the crossbar 303 to rotate via the bevel gear transmission belt 316, which in turn drives the double-headed telescopic rod 301 and the ellipsoidal block 302 to rotate. The ellipsoidal block 302 pushes the transmission roller 305 and the connecting housing 201 to move vertically back and forth, so that the microneedle array can periodically pierce the skin; the transmission spring 307 provides the reset force to ensure smooth movement. When disassembling, press the unlock button 209, and the drive cylinder 203 will move in the opposite direction to make the locking block 204 disengage from the locking groove 207, so that the microneedle array can be removed.

[0034] In use, the user aligns the mounting base 205 of the microneedle array with the limiting groove 208 on the bottom surface of the connecting housing 201, allowing the mounting base 205 to enter the limiting groove 208 for initial positioning. At this time, the snap-fit ​​groove 207 on the mounting base 205 is aligned with the snap-fit ​​block 204 on the inner side of the mounting frame 202. Pressing the unlock button 209 activates the drive cylinder 203, whose piston rod pushes the mounting frame 202 to slide horizontally along the inside of the connecting housing 201. As the mounting frame 202 slides, the snap-fit ​​block 204 gradually inserts into the snap-fit ​​groove 207, achieving snap-fit ​​fixation of the microneedle array. Because snap-fit ​​blocks 204 are provided on both inner walls and the crossbar of the mounting frame 202, and the limiting groove 208 restricts the position of the microneedle array, the microneedle array is constrained in both the horizontal and vertical directions, ensuring stable installation. If the microneedle 206 needs to be replaced, press the unlock button 209 again to retract the piston rod of the drive cylinder 203, and the microneedle array can be removed. Through the above steps, the microneedle array is quickly, accurately, and securely installed on the connecting housing 201, providing a stable foundation for subsequent insertion operations.

[0035] The core of the depth adjustment component 3 is the eccentric structure of the ellipsoidal block 302 and the contact transmission with the transmission roller 305. By changing the contact position between the ellipsoidal block 302 and the transmission roller 305, the maximum insertion depth of the microneedle can be continuously adjusted. The user rotates the adjustment knob 317. The adjustment knob 317 drives the second horizontal bar 313 to rotate, which in turn drives the second transmission wheel 315 to rotate. The second transmission wheel 315 drives the first transmission wheel 314 to rotate via the transmission belt 316. The first transmission wheel 314 drives the first horizontal bar 312 to rotate, which in turn drives the transmission gear 311 fixed on the first horizontal bar 312 to rotate. The transmission gear 311 meshes with the transmission rack 310, so the rotation of the transmission gear 311 drives the transmission rack 310 to move left and right. The transmission rack 310 drives the connecting vertical rod 309 to move, and the connecting vertical rod 309 drives the connecting sleeve 308 to move left and right around the cylinder of the double-headed telescopic rod 301. The movement of the connecting sleeve 308 causes the ellipsoidal block 302 to move synchronously, changing the contact position between the ellipsoidal block 302 and the transmission roller 305. Since the cross-section of the ellipsoidal block 302 is elliptical, and its major axis gradually increases while its minor axis remains constant from the first surface to the second surface, when the contact position is at the point where the major axis is smaller, the pushing force on the transmission roller 305 is smaller, resulting in a smaller maximum penetration depth of the microneedles. When the contact position is at the point where the major axis is larger, the pushing force on the transmission roller 305 is larger, the initial position of the connecting housing 201 is lower, and the maximum penetration depth of the microneedles is larger. By continuously changing the contact position, the maximum penetration depth of the microneedle array can be continuously adjusted.

[0036] When the device is needed, the user presses the switch button 321, and the drive motor 318 starts. The output shaft of the drive motor 318 drives the first bevel gear 319 to rotate. The first bevel gear 319 meshes with the second bevel gear 320, driving the second bevel gear 320 to rotate. The second bevel gear 320 is fixed on the connecting crossbar 303, so the connecting crossbar 303 rotates synchronously with the second bevel gear 320. One end of the connecting crossbar 303 is rotatably connected to the inner wall of the working cover 101, and the other end is fixedly connected to the piston rod of the double-headed telescopic rod 301, so the rotation of the connecting crossbar 303 drives the double-headed telescopic rod 301 to rotate. The rotation of the double-headed telescopic rod 301 drives the ellipsoidal block 302 on its cylinder to rotate synchronously. During the rotation, the ellipsoidal block 302 periodically pushes the transmission roller 305 up and down. The transmission roller 305 drives the connecting housing 201 to reciprocate along the vertical direction inside the working cover 101 through the connecting seat 304. The reciprocating movement of the connecting housing 201 drives the microneedle array to perform periodic insertion and withdrawal actions.
