Description

Technical Field

[0001] The utility model relates to the technical field of microneedle structures, in particular to a beauty microneedle structure. Background Technique

[0002] Most of the liquid medicines with therapeutic, health care or beauty effects are difficult to achieve the expected curative effect due to the too low skin penetration rate. In recent years, the curative effect of the liquid medicine can be effectively promoted through the penetration enhancement method. The principle is that a microneedle roller punctures the skin to generate a large number of micron-sized pores in the stratum corneum and the epidermis of the skin. Then, after the liquid medicine is coated on the skin punctured by the microneedles, the absorption efficiency of the skin for the liquid medicine is improved.

[0003] It is found that the Chinese utility model patent with the publication number of CN217526092U discloses a microneedle structure for microneedle beauty. Through the mutual cooperation of a roller, rolling microneedles and a matching disc, during the rolling process of the roller, the matching disc squeezes the skin on both sides towards the middle, so that the skin bulges, thereby increasing the contact area between the roller and the skin. Then, the rolling microneedles arranged obliquely puncture the skin surface to realize the function of forming micropores on the skin surface. And due to the oblique setting, when the rolling microneedles leave the micropores, there will be no problem of scratching and lifting the micropore edges like the vertically arranged microneedles, reducing skin damage. However, when the device moves and the roller drives the rolling microneedles to rotate circumferentially on the skin, the microneedles will still scratch and pick the edges of the micropores formed by puncturing the skin, resulting in skin damage.

[0004] Therefore, the utility model provides a beauty microneedle structure to solve the above problems. Content of the Utility Model

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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 creative efforts shall fall within the protection scope of the present invention.

[0027] Embodiment 1

[0028] The present invention provides a beauty microneedle structure, as Figures 1-5 shown. The microneedle structure includes a U-shaped frame 1 and a needle holder 3 connected to the U-shaped frame 1. A plurality of microneedles 31 are horizontally and equidistantly inserted at the bottom of the needle holder 3. Rollers 4 are provided at both ends of the needle holder 3. A synchronous shaft 41 fixedly connected to the shaft rod of the roller 4 is rotationally inserted at the top of the needle holder 3;

[0029] Intermittent components 2 are provided at both ends of the U-shaped frame 1 between the rollers 4 and the needle holder 3. An elastic component for resetting the microneedles 31 is provided inside the needle holder 3. The intermittent component 2 includes a housing 21 fixed to the end of the U-shaped frame 1. A ratchet 22 fixedly sleeved outside the synchronous shaft 41 is provided inside the housing 21. A pawl 23 that meshes with the ratchet 22 and is connected to the elastic component is rotatably provided inside the housing 21. A volute spring shaft 24 elastically connected to the shaft rod of the pawl 23 is fixedly connected to the housing 21; The elastic component can be used to reset the position of the microneedles 31. Through the cooperation of the intermittent component 2 and the elastic component, when the microneedles 31 puncture the skin, the general movement mode of the microneedles 31 is a lifting movement, avoiding the problem of scratches and lifting at the edges of the micropores when the rolling microneedles 31 leave the micropores, and reducing skin damage; During the lifting and lowering process of the microneedles 31, fine channels on the skin are formed and closed. This dynamic process helps the active ingredients to be more evenly distributed among different skin layers, improving the absorption efficiency; The intermittent stimulation of the microneedles 31 can better activate the natural healing mechanism of the skin, promote the generation of collagen and elastic fibers, and at the same time reduce the inflammatory reaction that may be caused by continuous stimulation;

[0030] During use, hold the grip 11 by hand to roll the roller 4 on the device on the surface of the skin. The roller 4 drives the synchronous shaft 41 to rotate clockwise. The synchronous shaft 41 drives the ratchet wheel 22 to rotate clockwise. While the ratchet wheel 22 rotates, it squeezes the pawl 23 to move. The pawl 23 drives the scroll spring shaft 24 to be stressed and store energy. At the same time, the pawl 23 squeezes the microneedle 31 to move downward, so that the microneedle 31 punctures the skin. During the process of the microneedle 31 moving downward, it squeezes the return spring 28 to contract and store energy. When the ratchet wheel 22 does not squeeze the pawl 23, under the action of the scroll spring shaft 24, the pawl 23 is reset, and at the same time, under the elastic force of the spring, the microneedle 31 is reset, so that the microneedle 31 moves back into the inside of the needle holder 3 again, thus completing an intermittent movement. As the roller 4 rotates, the microneedle 31 performs a complex intermittent movement.

[0031] Specifically, the elastic component includes a lifting plate 25 that is slidably sleeved in the needle holder 3 through a vertical groove 32 and is connected to the microneedle 31. Both ends of the lifting plate 25 are inserted into the housing 21 and are in contact with the outer side of the ratchet wheel 22 and correspond to the pawl 23. A return spring 28 for resetting the lifting plate 25 and the microneedle 31 is arranged in the needle holder 3; the return spring 28 is initially in a state of being squeezed, stressed, and storing energy.

[0032] Furthermore, a sliding groove 33 for inserting the microneedle 31 and communicating with the vertical groove 32 is opened at the bottom end of the needle holder 3. The sliding groove 33 is slidably sleeved with a lifting rod 26 fixedly connected to the lifting plate 25 and the microneedle 31. A limiting groove 34 is opened in the sliding groove 33. A limiting sliding plate 27 fixedly sleeved outside the lifting rod 26 is slidably sleeved in the limiting groove 34. The return spring 28 is sleeved outside the lifting rod 26 and is located between the bottom end of the limiting sliding plate 27 and the limiting groove 34; during the process of the pawl 23 squeezing the lifting plate 25 to move downward, the lifting plate 25 drives the lifting rod 26 and the microneedle 31 to move downward to puncture the skin. While the lifting rod 26 moves downward, it squeezes the return spring 28 through the limiting sliding plate 27 to contract and store energy, and then the microneedle 31 can be lifted and lowered under the elastic force of the spring.

[0033] Furthermore, a grip 11 is threadedly inserted at the top end of the U-shaped frame 1. The grip 11 is connected by a threaded method, which is convenient for installing the grip 11 and can also disassemble and replace the grip 11.

[0034] Furthermore, annular grooves sleeving the outside of the scroll spring shaft 24 are opened at the opposite ends of the two rollers 4.

[0035] Embodiment 2

[0036] Refer to the appendix Figure 1 and the appendix Figure 2As shown, the micro-needle 31 structure further includes a fine-tuning mechanism 5 on both sides of the top of the needle base 3. The fine-tuning mechanism 5 includes a guiding slide rod 51 that is slidably inserted into the U-shaped frame 1 and fixedly connected to the top of the needle base 3. A baffle 53 is fixedly connected to the top of the guiding slide rod 51. A fastening spring 52 is sleeved outside the guiding slide rod 51 and between the top of the needle base 3 and the U-shaped frame 1. The fastening spring 52 is initially in a compressed and stressed state and stores energy. While facilitating the connection between the needle base 3 and the U-shaped frame 1 through the guiding slide rod 51, it can also enable the needle base 3 to perform a lifting motion. The elastic force of the spring can keep the bottom of the needle base 3 in contact with the skin at all times. The fine-tuning mechanism 5 can reduce the friction generated when the device moves on the skin and improve the user experience.

[0037] Furthermore, a fine-tuning groove 35 is formed at the top of the needle base 3 and is sleeved outside the synchronization shaft 41.

[0038] 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
