The bottom of the lower syringe 5 extends downward along the central cavity column 502 and is provided with an extended cavity column 504. The positioning sleeve 703 and the extended cavity column 504 slide up and down. The top of the needle core 8 is fixedly connected with the sealing gasket 3, and the needle core 8 coaxially passes through the central cavity column 502 and the extended cavity column 504 in sequence and extends from the bottom of the lower syringe 5. The needle core 8 includes a needle rod 801, and a sewage discharge cavity 802 is provided inside the needle rod 801 along the axial direction. A needle head 803 is fixedly provided at the bottom of the needle rod 801, and suction holes 8031 ​​are penetrated on both sides of the needle head 803, and the suction hole 8031 ​​is connected with the sewage discharge cavity 802.

[0035] Specifically, by setting the upper syringe 4, the lower syringe 5, the rotating member 6 and the lifting member 7, when treating acne, firstly, by rotating the rotating member 6, the lifting member 7 starts to move downward until the positioning sleeve 703 at the bottom thereof is disengaged downward from the extension cavity column 504, and then the positioning sleeve 703 is aligned with the acne site, and then the adjusting screw 1 is used to control and adjust the needle core 8 to gradually extend forward along the axial direction until the needle head 803 at the front end contacts and punctures the acne, and the moving direction of the needle head 803 is always kept on the same axis as the positioning sleeve 703, thereby effectively improving the needle head The precision of puncture by 803 is that after puncturing the acne, the wound area is gently squeezed by the positioning pressure sleeve 703 to make the pus inside the acne overflow, and then the pus is sucked and cleaned through the suction hole 8031 ​​on the needle 803, and the pus is drawn into the drainage cavity 802 for discharge, ensuring that the pus will not remain on the wound, with high cleanliness, safety and hygiene. After cleaning, the needle core 8 is controlled to retract by the adjusting screw 1, and the powder inside the medicine cavity 503 is sprayed from the bottom opening onto the cleaned wound, realizing an efficient treatment process of puncturing, squeezing, cleaning and medicine application for acne.

[0036] like Figure 3 As shown, the adjusting screw 1 is threadedly matched with the top end of the end cover 2, a rotating head 101 is fixedly provided at the bottom of the adjusting screw 1, a baffle 102 is rotatably installed on the rotating head 101, a spring seat 301 is fixedly provided at the center of the upper end of the sealing gasket 3, and an extrusion spring 103 is provided between the baffle 102 and the spring seat 301.

[0037] Specifically, the sealing gasket 3 in this embodiment is made of rubber material and has a certain elasticity. When the adjusting screw 1 is rotated, the adjusting screw 1 will drive the baffle 102 to move synchronously through the rotating head 101. The baffle 102 will drive the sealing gasket 3 to deform through the extrusion spring 103 during the displacement process, so that the needle core 8 at the bottom of the sealing gasket 3 can move up and down with the rotation adjustment of the adjusting screw 1, thereby allowing the needle core 8 to extend forward or retreat backward. At the same time, the sealing gasket 3 can also play a role in waterproofing and moisture-proofing, and make the medicine storage cavity 401 have good sealing performance, which can ensure that the medicine powder inside it remains dry and does not leak.

[0038] like Figure 3 As shown, an outer shell 402 is provided on one side of the upper syringe 4, and a micro suction pump 4021 and a power supply 4022 are respectively provided inside the outer shell 402. The sewage discharge cavity 802 is connected to the micro suction pump 4021 through a sewage discharge pipe 807. A drug inlet 403 is provided on the other side of the upper syringe 4, and the drug inlet 403 is communicated with the drug storage cavity 401.

[0039] Specifically, the power supply 4022 provides power for the micro suction pump 4021, which will suction and discharge the pus sucked into the sewage cavity 802 through the sewage pipe 807. The entire suction and discharge process is carried out from the internal sewage cavity 802 and will not cause contamination to the medicinal powder in the medicine storage cavity 401. Therefore, the liquid inlet can be used to replenish the medicinal powder into the medicine storage cavity 401.

[0040] like Figure 5 and Figure 6 As shown, a sealing protrusion 5041 is provided on the inner wall of the extension cavity column 504, and a sealing plug 804 is provided on the outer circumference of the needle rod 801. The sealing plug 804 is slidably installed in the sealing protrusion 5041 up and down, and the sealing plug 804 cooperates with the sealing protrusion 5041 to close the bottom opening of the medicine cavity 503.

[0041] Specifically, when the needle rod 801 extends forward, the sealing plug 804 will slide downward into the sealing protrusion 5041, wherein the outer diameter of the sealing plug 804 is slightly smaller than the inner diameter of the sealing protrusion 5041, which makes it difficult for the powder in the medicine upper chamber 503 to leak, thereby achieving the effect of sealing the medicine upper chamber 503; and when the needle rod 801 retreats backward, the sealing plug 804 will slide upward into the medicine upper chamber 503. Since the outer diameter of the needle rod 801 is much smaller than the inner diameter of the sealing protrusion 5041, the powder in the medicine upper chamber 503 will be sprayed out along the extension cavity column 504, thereby completing the medicine application process.

[0042] like Figure 3 , Figure 5 and Figure 6 As shown, a fixed plate 405 is provided at the bottom of the medicine storage cavity 401, and a first row of medicine holes 4051 are evenly penetrated on the fixed plate 405, a threaded section 805 is provided on the needle rod 801, and a movable plate 806 is rotatably screwed on the threaded section 805, and a second row of medicine holes 8061 are penetrated on the movable plate 806, and the aperture shape and distribution arrangement of the first row of medicine holes 4051 and the second row of medicine holes 8061 are consistent, a rotating groove 507 is provided on the inner wall of the upper medicine cavity 503, and the movable plate 806 is rotatably installed in the rotating groove 507, and the bottom end of the fixed plate 405 is abutted against the top end of the movable plate 806.

[0043] Specifically, by setting a fixed plate 405 and a movable plate 806, the needle rod 801 will drive the movable plate 806 to rotate through the threaded section 805 during the up and down movement. When the movable plate 806 rotates, the second row of medicine holes 8061 thereon will intermittently overlap and align with the first row of medicine holes 4051 on the fixed plate 405. At this time, the medicine powder in the medicine storage chamber 401 will leak into the medicine supply chamber 503 through the first row of medicine holes 4051 and the second row of medicine holes 8061. When the movement stroke of the needle rod 801 is the same each time, the rotation frequency of the movable plate 806 will also be the same. Therefore, the number of times the first row of medicine holes 4051 and the second row of medicine holes 8061 are aligned will also be the same, so that the amount of medicine powder each time the medicine is supplied can be accurately controlled to remain consistent. At the same time, the first row of medicine holes 4051 and the second row of medicine holes 8061 also play a role in filtering the medicine powder, which can effectively remove the condensed particles mixed in the medicine powder, which is beneficial to improving the treatment effect.

[0044] like Figure 2 , Figure 4 and Figure 5 As shown, a give-way groove 501 is provided on the side wall of the upper syringe 4, a lever 602 is fixedly provided on the outer wall of the rotating member 6, and the lever 602 is adapted to be rotatably installed in the give-way groove 501, a limiting annular groove 506 is circumferentially provided on the inner wall of the lower syringe 5, and a limiting block 603 is fixedly provided on the outer wall of the rotating member 6, and the limiting block 603 is adapted to be slidably installed in the limiting groove.

[0045] Specifically, when the rotating part 6 needs to be rotated, the lever 602 can be controlled to rotate along the clearance groove 501, thereby driving the rotating part 6 to rotate in the upper needle cylinder 4. During this process, the limit block 603 always keeps sliding in the limit groove, which is beneficial to improving the rotation stability. At the same time, when rotating, the outer wall of the rotating part 6 will always be close to the clearance groove 501, so that the lower needle cylinder 5 maintains a good sealing effect.

[0046] like Figure 3 and Figure 5 As shown, a slot 404 is provided at the bottom outer side of the upper syringe 4, and a hook tongue 505 is provided at the top outer side of the lower syringe 5. The hook tongue 505 is engaged with the slot 404. Through the engagement of the hook tongue 505 and the slot 404, the upper syringe 4 and the lower syringe 5 can be quickly positioned and installed, and disassembly is convenient.

[0047] The working principle of the present invention is as follows: Figure 1-Figure 7 As shown, when treating acne, firstly, the lifting member 7 starts to move downward by rotating the rotating member 6 until the positioning sleeve 703 at the bottom thereof is disengaged downward from the extending cavity column 504, and then the positioning sleeve 703 is aligned with the acne site, and then the adjusting screw 1 is used to control and adjust the needle core 8 to gradually extend forward along the axial direction until the needle head 803 at the front end contacts the acne and punctures it. The moving direction of the needle head 803 is always kept on the same axis as the positioning sleeve 703, thereby effectively improving the accuracy of the puncture of the needle head 803. After acne, the positioning pressure sleeve 703 is used to gently squeeze the wound area to make the pus inside the acne overflow, and then the pus is sucked and cleaned through the suction hole 8031 ​​on the needle 803. The pus is drawn into the drainage cavity 802 for discharge, ensuring that the pus will not remain on the wound. The cleanliness is high, safe and hygienic. After cleaning, the needle core 8 is controlled to retract by the adjusting screw 1, and the powder inside the medicine cavity 503 is sprayed from the bottom opening onto the cleaned wound, realizing an efficient treatment process of puncturing, squeezing, cleaning and applying medicine for acne.

[0048] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention.
