[0038] As Figure 2 and Figure 3As shown in the figure, the driving structure includes a mounting bracket 151, which is fixedly connected to the inside of the outer shell 11. The bottom end of the mounting bracket 151 is fixedly connected to an electric push rod 152, and the bottom end of the electric push rod 152 is fixedly connected to a connecting plate 153. The driving structure also includes a motor 154, which is fixedly connected to the bottom end of the connecting plate 153. The bottom end of the motor 154 is drivingly connected to a connecting rod 155, and the connecting rod 155 is clamped with the base 18. A card slot 156 is annularly arranged on the outer wall of the end of the connecting rod 155 away from the motor 154. During use, the electric push rod 152 is controlled to operate through a control button. The connecting plate 153 fixed to the bottom end of the electric push rod 152 drives the base 18 on the connecting rod 155 at the bottom end of the motor 154 to move as the electric push rod 152 operates, so as to adjust the height of the needle 13.

[0039] As Figure 4 shown in the figure, the cleaning structure includes a liquid inlet pipe 191, which is rotatably connected to the top end of the liquid storage cylinder 16. Liquid outlet holes 192 are arranged at equal intervals on the outer wall of the liquid inlet pipe 191. The cleaning structure also includes fixing rods 193, which are fixedly connected to both ends of the liquid inlet pipe 191. One end of the fixing rod 193 away from the liquid inlet pipe 191 is fixedly connected to a mounting plate 194, and cleaning brushes 195 are fixedly connected at equal intervals to the end of the mounting plate 194 away from the fixing rod 193, and the cleaning brushes 195 are movably connected to the liquid storage cylinder 16. During use, the cleaning agent is poured into the liquid inlet pipe 191 through the opening on the liquid inlet pipe 191, and the liquid outlet holes 192 arranged on the outer wall of the liquid inlet pipe 191 discharge the cleaning agent. Hold the liquid inlet pipe 191 and rotate it. The fixing rods 193 fixed to both ends of the liquid inlet pipe 191 drive the mounting plate 194 to rotate as the liquid inlet pipe 191 rotates. The cleaning brushes 195 arranged at equal intervals on the mounting plate 194 rub against the inner wall of the liquid storage cylinder 16 as the mounting plate 194 rotates, so as to clean the excess dye in the liquid storage cylinder 16. The cleaned dye and cleaning agent are discharged through the liquid outlet pipe 171 and the guide pipe 172, which can ensure the purity of the dye for subsequent use.

[0040] As Figure 2 shown in the figure, the blocking structure includes a mounting seat 211, which is fixedly connected to the outer wall of the outer shell 11 in a linear array. A movable shaft 212 is rotatably connected to the middle of the mounting seat 211, and a baffle 213 is fixedly connected to the outer wall of the movable shaft 212. During use, hold the baffle 213 and rotate it. The movable shaft 212 fixed to one end of the baffle 213 rotates on the mounting seat 211 as the baffle 213 rotates, so as to cover buttons at different positions, prevent the operator from accidentally touching the buttons during use and causing work mistakes, and causing harm to the user.

[0041] As Figure 3 shown, the fixing structure includes a clamping block 321 which is slidably connected inside the installation groove 31, and the clamping block 321 is clamped with the clamping groove 156. One end of the clamping block 321 close to the installation groove 31 is fixedly connected with a moving block 322. Both sides of the moving block 322 are fixedly connected with sliding blocks 323, and the sliding blocks 323 are slidably connected with the sliding grooves 33. One end of the moving block 322 away from the clamping block 321 is fixedly connected with a spring 324, and the spring 324 is fixedly connected with the installation groove 31. During use, hold the base 18 and move it. The clamping block 321 installed in the clamping groove 156 is squeezed as the base 18 moves. The moving block 322 fixed on one side of the clamping block 321 drives the sliding block 323 to move in the sliding groove 33 as the clamping block 321 is squeezed, thereby squeezing the spring 324, so that the clamping block 321 is removed from the clamping groove 156, facilitating the removal of the base 18 from the connecting rod 155 and replacing the base 18 of different specifications, enabling the base 18 to install and fix needles 13 of different models.

[0042] Working principle: First, when the device needs to be used, hold the base 18 and move it according to the user's pore and hair tattooing needs. The block 321 installed in the card slot 156 is squeezed as the base 18 moves. The moving block 322 fixed to one side of the block 321 drives the slider 323 to move in the chute 33 with the squeezing of the block 321, thereby squeezing the spring 324, causing the block 321 to move out of the card slot 156, facilitating the removal of the base 18 from the connecting rod 155 and replacing the base 18, enabling the base 18 to install and fix needles 13 of different models. Then, press the switch to start the device. Control the operation of the electric push rod 152 through the control button. The connecting plate 153 fixed to the bottom end of the electric push rod 152 drives the base 18 on the connecting rod 155 at the bottom end of the motor 154 to move with the operation of the electric push rod 152 to adjust the height of the needle 13. The dye is conveyed into the liquid storage cylinder 16 through the feed pipe on the liquid storage cylinder 16. Control the flow specification of the dye in the liquid outlet pipe 171 through the liquid control valve 14. The guiding pipe 172 fixed to the bottom end of the liquid outlet pipe 171 discharges the dye in the liquid outlet pipe 171 close to the needle 13 under the control of the liquid control valve 14. The discharged dye falls onto the scalp through the through hole at the bottom end of the connection shell 12. The motor 154 operates, and the connecting rod 155 fixed to the bottom end of the motor 154 drives the needle 13 to rotate with the operation of the motor 154, causing the needle 13 to drive the dye to quickly penetrate into the scalp for hair tattooing. Finally, pour the cleaner into the liquid inlet pipe 191 through the opening on the liquid inlet pipe 191. The liquid outlet 192 opened on the outer wall of the liquid inlet pipe 191 discharges the cleaner. Hold the liquid inlet pipe 191 and rotate it. The fixing rods 193 fixed to both ends of the liquid inlet pipe 191 drive the mounting plate 194 to rotate with the rotation of the liquid inlet pipe 191. The cleaning brushes 195 arranged at equal intervals on the mounting plate 194 rub against the inner wall of the liquid storage cylinder 16 with the rotation of the mounting plate 194 to clean the excess dye in the liquid storage cylinder 16. The cleaned dye and cleaner are discharged through the liquid outlet pipe 171 and the guiding pipe 172, which can ensure the purity of the dye for subsequent use.

[0043] The above is only a preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
