[0030] like Figure 1 to Figure 2 As shown, a needle structure includes a first body 1 and a vibration connecting column 14. A limiting column 12 is provided in the first body 1, and a through hole 13 is provided on the limiting column 12. The vibration connecting column 14 moves up and down in the through hole 13. A cavity 15 for holding essence is formed between the limiting column 12 and the inner wall of the first body 1. An essence output hole 11 is provided at the head of the first body 1, and the essence output hole 11 is connected to the cavity 15. A sharp needle component 16 is fixed on the top of the vibration connecting column 14, and a plurality of sharp needles 161 are provided on the sharp needle component 16. A vibration connector 17 is connected to the bottom of the vibration connecting column 14. The vibration connector 17 is used to drive the vibration connecting column 14 to reciprocate up and down so that the sharp needles 161 reciprocate up and down. The vibration connecting column 14 is driven to reciprocate up and down by the vibration connector 17, so that the sharp needles 161 reciprocate up and down, thereby realizing the acupuncture function. At the same time, the essence in the cavity 15 is output through the essence output hole 11, so that the essence is output while acupuncture. This has changed the previous shortcomings of microneedle products of similar size, which only had a single function of acupuncture, or had multiple functions but were bulky, greatly improving the user experience of microneedle users.

[0031] Specifically, Figure 2 As shown, the needle component 16 includes a second body 163 and a fixing plate 162. One end of the second body 163 is connected and fixed to the vibration connecting column 14, and the other end is connected and fixed to the fixing plate 162. A plurality of needles 161 are fixed to the top of the fixing plate 162. The plurality of needles 161 are provided to expand the range of acupuncture and effectively promote the absorption of the essence.

[0032] Specifically, Figure 2 As shown, the needle structure also includes a first spring 18, one end of the first spring 18 stops at the vibration connector 17, and the other end stops at the limiting column 12. The first spring 18 is used to facilitate the resetting of the vibration connecting column 14, so that the sharp needle 161 can move up and down smoothly, thereby improving the user experience.

[0033] Specifically, Figure 2As shown, a sealing silicone ring 19 is provided between the limiting column 12 and the inner wall of the first body 1, and the sealing silicone ring 19 is used to prevent the essence from leaking out.

[0034] Specifically, the sharp needle 161 is a stainless steel sharp needle, and the diameter of the sharp needle 161 is 0.25 mm.

[0035] Specifically, there are four essence output holes 11. When the sharp needle 161 contacts the human skin, under the combined effect of the tension of the liquid and the vibration generated by the sharp needle 161 itself, different liquid output speeds can be achieved according to different vibration frequencies, thereby using the electric microneedle as a whole to achieve the combined functional effects of acupuncture and essence output synchronously.

[0036] like Figures 3 to 6 As shown, an electric microneedle device includes an electric microneedle mechanism, and Figure 1 to Figure 2 The needle structure shown, the electric microneedle mechanism includes a housing 2, a rotating assembly 22 arranged at the top of the housing 2 and a control assembly arranged at the bottom of the housing 2, a driving assembly 23 is arranged between the rotating assembly 22 and the control assembly, the driving assembly 23 is electrically connected to the control assembly, the rotating assembly 22 is connected to the first body 1, the rotating assembly 22 is used to adjust the relative position of the first body 1 and the sharp needle 161, the driving assembly 23 is provided with a vibration head 21, the vibration head 21 is connected to the vibration connector 17, and the vibration head 21 is used to drive the vibration connector 17 to reciprocate up and down. The relative position of the first body 1 and the sharp needle 161 is adjusted by the rotating assembly 22, so that the sharp needle 161 can be pushed out or retracted, and the depth adjustment of microneedle acupuncture is realized. The vibration connector 17 is driven to reciprocate up and down by the vibration head 21, thereby driving the sharp needle 161 to reciprocate up and down to realize the acupuncture function, and at the same time, the essence in the cavity 15 is output through the essence output hole 11, so that the essence is output while acupuncture, which greatly increases the user experience of the microneedle user.

[0037] Specifically, Figure 5 to Figure 6 As shown, the rotating assembly 22 includes a first rotating sleeve 221, a rotating active sleeve 222 and a rotating driven sleeve 223. The first main body 1 abuts against the rotating driven sleeve 223. One end of the rotating active sleeve 222 is connected to the first rotating sleeve 221, and the other end is connected to the rotating driven sleeve 223. The first rotating sleeve 221 is adjusted to adjust the rotation driven sleeve 223 to rise or fall. The first rotating sleeve 221 is manually rotated to drive the rotating active sleeve 222 to rotate, and the rotating active sleeve 222 rotates to drive the rotating driven sleeve 223 to rise or fall. Since the first main body 1 abuts against the rotating driven sleeve 223, the rising or falling of the rotating driven sleeve 223 can synchronously drive the first main body 1 to rise or fall, so that the sharp needle 161 can be pushed out or retracted, and the depth adjustment of microneedle acupuncture is achieved.

[0038] Specifically, Figure 5 to Figure 6As shown, the top of the rotating active sleeve 222 is snap-fitted with the first rotating sleeve 221, and the snap-fitting connection is quick, convenient, and firmly connected. The bottom of the rotating active sleeve 222 is threadedly connected with the rotating driven sleeve 223, and the rotation of the rotating active sleeve 222 is converted into the linear motion of the rotating driven sleeve 223 through the threaded connection to drive the first body 1 to rise or fall, with a simple structure and reasonable design.

[0039] Specifically, Figure 5 to Figure 6 As shown, the driving assembly 23 includes a motor 231, a cam 232, a fixing seat 233 and a limit piece 234. The vibration head 21 is arranged on the fixing seat 233, the cam 232 is arranged in the limit piece 234 and stops at the vibration head 21, the output shaft of the motor 231 is connected to the cam 232, and the rotation of the cam 232 is used to drive the vibration head 21 to rise or fall, one end of the limit piece 234 is connected to the bottom of the fixing seat 233, and the other end is connected to the top of the motor 231, the head of the limit piece 234 is fixedly connected to the shell 2, and also includes a fixing ring 235, the inner wall of the fixing ring 235 is clamped with the motor 231, the outer wall of the fixing ring 235 is fixedly connected to the shell 2, and the fixing ring 235 is used to fix the motor 231. Since the output shaft of the motor 231 is connected to the cam 232, the cam 232 stops at the vibration head 21. When the motor 231 is powered on, its output shaft rotates to drive the cam 232 to rotate, and the rotation of the cam 232 drives the vibration head 21 to reciprocate up and down. By designing the cam 232, the rotation of the cam 232 is cleverly converted into a linear motion of the vibration head 21, thereby driving the vibration head 21 to reciprocate up and down, and driving the vibration connecting head 17 to reciprocate up and down, thereby driving the sharp needle 161 to reciprocate up and down, realizing the acupuncture action.

[0040] Specifically, Figure 5 to Figure 6 As shown, the vibration head 21 includes a vibration body 211 and a connecting portion 212 extending from the vibration body 211. The outer periphery of the vibration body 211 is provided with a second spring 24, one end of the second spring 24 abuts against the connecting portion 212, and the other end abuts against the fixing seat 233. The second spring 24 is provided to facilitate the reset of the vibration head 21, so that the up and down reciprocating motion of the needle 161 can be smoothly performed, thereby improving the user experience. A rotating ring 213 is provided in the outer periphery of the vibration body 211, and the rotating ring 213 is provided below the connecting portion 212. The rotating ring 213 abuts against the outer surface of the cam 232, and the friction is reduced by providing the rotating ring 213.

[0041] Specifically, Figure 5 to Figure 6As shown, the control component includes a battery 25, a control mainboard 26, a wireless charging coil 27, an operation panel 28 and a control button 29.

The operation panel 28 and the control button 29 are provided to facilitate operation. The electric microneedle can be used while the vibration rate of the microneedle can be checked and adjusted through a mobile phone. The wireless charging coil 27 can realize wireless charging of the battery 25.

[0042] Specifically, the control chip model on the control main board 26 is STM8L151G6U6TR.

[0043] Specifically, the control main board 26 is electrically connected to a Bluetooth module (not marked in the figure) for communication, and the model of the Bluetooth module is JGH-02.

[0044] Compared with the prior art, the present invention provides a needle structure and an electric microneedle device.

At the same time, the essence in the cavity is output through the essence output hole, so that the essence is output while acupuncture. It has changed the disadvantage that the microneedle products with similar volume in the past only have the single function of acupuncture, or have achieved the disadvantage of complex functions but large volume, which greatly improves the user experience of microneedle users. The electric microneedle device adjusts the relative position of the first body and the sharp needle through the rotating component, so that the sharp needle can be pushed out or retracted to achieve the depth adjustment of microneedle acupuncture.
