Description

Technical Field

[0001] This invention belongs to the field of microneedling aesthetic technology, specifically referring to a microneedling aesthetic device. Background Technology

[0002] Microneedling is a transdermal technology that has emerged in the consumer market in recent years, attracting widespread attention in the fields of beauty and medicine. The principle of microneedling is to use the microneedle structure to disrupt the epidermis, creating micron-sized channels that allow the active ingredients of drugs to be directly delivered into the dermis. In this way, drugs or active substances can participate in microcirculation directly without passing through the stratum corneum barrier.

[0003] The thickness and structure of skin vary in different areas, making the selection of the appropriate needle length crucial for ensuring treatment effectiveness and safety during microneedling. Overly long needles not only increase pain but may also cause adverse reactions such as local edema and bleeding, affecting the safety and comfort of the treatment. Conversely, overly short needles may compromise the treatment's effectiveness. For example, the skin on the forehead and cheekbones is relatively thin, so shorter needles are typically used, while the skin on the chin, T-zone, and cheekbones is thicker and can tolerate longer needles. Furthermore, the skin around the eyes is very thin and easily injured, requiring special care to avoid using excessively long needles. However, most existing microneedling devices lack adjustable needle depth and use needles of the same length for treatment. Additionally, applying a skincare product to the skin during microneedling is inconvenient by hand. While current technologies allow for simultaneous application and microneedling, this is often simply spraying the product onto the microneedles or skin surface, relying solely on the needle insertion for absorption. This may not effectively promote the penetration of the skincare product, leaving some residue on the skin surface. Finally, cold compresses are necessary after microneedling treatment. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a microneedle beauty device that can finely adjust the movement of the microneedle to control the insertion depth, making it convenient to perform insertion at different depths for different parts of the body.

[0005] The technical solution adopted by this invention is as follows: This invention provides a microneedling beauty device, including a handle, a quick-release fixing bracket, and a roller rotatably disposed at the bottom end of the quick-release fixing bracket. The handle is disposed at the upper end of the quick-release fixing bracket. Microneedles are evenly and densely distributed on the circumferential side of the roller. The quick-release fixing bracket is provided with a puncture depth limiting component. A pre-tensioning application component is oscillating at the front end of the quick-release fixing bracket. A rolling cold compress component is provided at the rear end of the quick-release fixing bracket. A liquid storage bottle is detachably connected inside the handle. Through holes are arrayed on the inner top wall of the quick-release fixing bracket, and the liquid storage bottle communicates with the through holes. The puncture depth limiting component includes a threaded sleeve, a depth adjusting screw, and a spherical end. The threaded sleeve is disposed on the side wall of the quick-release fixing bracket. The depth adjusting screw is threadedly connected inside the threaded sleeve, and the spherical end is disposed at the bottom end of the depth adjusting screw.

[0006] By adjusting the height of the spherical tip, the depth of microneedle insertion can be adjusted, allowing for insertion to different depths on different parts of the skin without changing the roller.

[0007] Preferably, the pre-tensioning coating assembly includes a swing arm, a swing shaft, a tensioning torsion spring, a rotating bracket, and a tensioning roller. The front end of the quick-release fixing bracket is provided with a swing groove. The swing shaft is rotatably disposed in the swing groove. One end of the swing arm is rotatably connected to the swing shaft. The tensioning torsion spring is disposed between the swing arm and the swing groove. The swing arm is obliquely disposed at the front end of the quick-release fixing bracket. The rotating bracket is disposed at the end of the swing arm away from the swing shaft. The tensioning roller is rotatably disposed at the bottom end of the rotating bracket. The length from the tensioning roller to the swing shaft is greater than the length from the roller to the swing shaft.

[0008] During use, the tension spring keeps the swing arm swinging towards the roller. When the microneedling device approaches the patient's skin, the tension roller first contacts the patient's skin. As the microneedling device continues to approach the patient's skin, the tension roller presses tightly against the patient's skin surface. The quick-release fixing bracket causes the tension roller to tend to move forward, thus tightening the patient's skin. When the microneedles on the roller surface contact the patient's skin, the tension roller tightens the patient's skin. As the roller moves forward, the tension roller moves forward as well, pushing the skin forward, always keeping the patient's skin taut. This keeps the epidermis and dermis in a flat state, allowing the needles to act more evenly on the target layer, and can temporarily reduce skin sensitivity. Especially in sensitive areas such as around the eyes and lips, moderate tightening can significantly reduce pain.

[0009] As a further improvement to this solution, the handle includes a fixed housing fixedly installed on the upper end of a quick-release fixed bracket and a movable housing snapped onto the upper end of the fixed housing. The quick-release fixed bracket is provided with an atomizing chamber, and the fixed housing is provided with a threaded mounting seat. The liquid storage bottle is threadedly connected to the threaded mounting seat. An atomizing channel is provided between the threaded mounting seat and the atomizing chamber. An atomizing plate is provided in the atomizing channel, and the through hole is connected to the atomizing chamber.

[0010] Furthermore, a tapping absorption-aiding component is provided between the pre-tensioning coating component and the roller. The tapping absorption-aiding component includes a tapping swing arm, a tapping bracket, a tapping torsion spring, and a tapping roller. One end of the tapping swing arm is rotatably disposed in a swing groove, and the tapping bracket is fixedly installed at the other end of the tapping swing arm. The tapping torsion spring is disposed between the tapping swing arm and the swing groove. The tapping roller is rotatably disposed at the bottom end of the tapping bracket. Arc-shaped spring pieces are arranged in an array along the circumferential direction on the surface of the tapping roller. An arc-shaped cover plate is provided on the tapping bracket. A cavity is provided inside the arc-shaped cover plate. An array of openings is distributed on the bottom wall of the cavity. A flexible tube is provided to connect the cavity and the atomization chamber.

[0011] During use, the patting roller rotates on the skin surface. As the curved spring rotates from front to back, the curved cover pushes the curved spring towards the side wall of the patting roller from the base of the curved spring. The curved spring rotates from back to front inside the curved cover. During the rotation, the atomized skin care water flows through the atomization chamber, the tube, the cavity, and the opening to the side wall of the curved spring. When the curved spring rotates from back to front and out of the curved cover, it unfolds and moves away from the side wall of the patting roller under its own elasticity, gently patting onto the patient's skin. Through the atomization of the skin care water and the gentle patting of the curved spring, the absorption of the skin care water is accelerated.

[0012] Furthermore, the rolling cold compress assembly includes a cold compress bracket and a cold compress roller. The rear end of the quick-release fixed bracket is provided with a sliding sleeve with an opening at the bottom. The top end of the cold compress bracket is provided with a sliding rod, which slides upward and is inserted into the sliding sleeve. A retaining spring is provided between the top end of the sliding rod and the sliding sleeve. The cold compress roller is rotatably disposed inside the cold compress bracket. The top of the cold compress bracket is provided with a cooling groove. From the inside to the outside, the cooling groove is provided with a semiconductor cooling chip and a cooling plate. The top of the cold compress roller contacts the cooling plate. The semiconductor cooling chip cools the roller and the cooling is transferred to the cold compress roller through the cooling plate.

[0013] Preferably, the tensioning roller is provided with a heating wire inside, and the operating temperature of the heating wire is 40℃-65℃.

[0014] The heating wire can heat the taut roller, pre-heating the skin before the microneedles on the roller surface, relaxing the skin and helping to open pores to some extent, so that the microneedles can more effectively deliver active ingredients into the deeper layers of the skin, improving the treatment effect.

[0015] Preferably, the cooling compress support is provided with a vertical groove, and the cooling compress roller is provided with a rotating shaft on both sides. The rotating shaft is slidably disposed in the vertical groove, and the side wall of the rotating shaft is rotatably fitted with the inner wall of the vertical groove. The front end of the vertical groove is connected to an upwardly oriented feeding groove. The side of the feeding groove away from the vertical groove is open. The rotating shaft is fed into the vertical groove through the open side of the feeding groove. When the microneedle beauty device moves down close to the skin, the cooling compress roller is pushed up, thereby driving the rotating shaft to move up along the vertical groove and get stuck in the vertical groove. The open side of the feeding groove is provided with an anti-detachment flexible protrusion, which can be made of rubber material.

[0016] The quick-release fixing bracket has rotating slots on both sides of its inner walls, and pressing grooves on both sides of the roller. An end cover is slidably installed in the pressing groove. A rotating pin is provided on the side wall of the end cover. A quick-release spring is provided between the end cover and the pressing groove.

[0017] The quick-release spring pushes the end cap to move to both sides of the roller. When it is necessary to install the roller into the quick-release fixing bracket, press the end cap inward so that the end cap retracts into the pressing slide groove, and then send the roller into the quick-release fixing bracket. Then, release the end cap and move the roller so that the rotating pin is aligned with the rotating slot. When the rotating pin is aligned with the rotating slot, the quick-release spring pushes the end cap back to its original position, so that the rotating pin is engaged in the rotating slot, completing the installation of the roller.

[0018] Preferably, the sidewall and top of the cooling support are provided with heat dissipation holes that communicate with the cooling tank, so as to facilitate heat dissipation of the semiconductor cooling chip.

[0019] Preferably, the cooling plate and the cooling roller are made of titanium alloy or stainless steel.

[0020] Preferably, the quick-release fixing bracket contains a battery, which is electrically connected to the atomizing plate, heating wire, and semiconductor cooling plate, and the handle side wall is provided with a switch button.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: 1. A puncture depth limiting component is set up. By rotating the depth adjustment screw, the depth of microneedle insertion into the skin can be adjusted. Without changing the roller, different depths of insertion can be performed on different parts of the skin.

[0022] 2. After pressing the tension roller firmly onto the patient's skin, the quick-release fixation bracket moves downward, causing the tension roller to tend to move forward, thus tightening the patient's skin. As the roller moves forward, the tension roller moves forward as well, pushing the skin forward, keeping the patient's skin taut at all times. This keeps the epidermis and dermis in a flat state, allowing the needle to act more evenly on the target layer, and can temporarily reduce skin sensitivity. Especially in sensitive areas such as around the eyes and lips, moderate tightening can significantly reduce pain.

[0023] 3. A patting absorption aid is set between the pre-tightening application component and the roller. Before the roller needle is inserted, the skin care water is patted onto the skin surface by the curved spring to accelerate the absorption of the skin care water.

[0024] 4. A cooling roller is installed behind the roller, which can apply a cooling compress to the area after microneedling treatment in real time, thereby reducing the inflammatory response by lowering the tissue temperature.

[0025] 5. The quick-release fixed bracket and the end caps that slide on both sides of the roller facilitate quick disassembly and replacement of the roller.

[0026] 6. An electric heating wire is installed inside the tensioning roller to preheat the skin before microneedle insertion, relax the skin, and help open pores to a certain extent, so that the microneedles can more effectively deliver active ingredients into the deeper layers of the skin and improve the treatment effect.

[0035] The pre-tensioning coating assembly 5 includes a swing rod 23, a swing shaft 24, a tensioning torsion spring 25, a rotating bracket 26, and a tensioning roller 27. The front end of the quick-release fixing bracket 2 is provided with a swing groove 28. The swing shaft 24 is rotatably disposed in the swing groove 28. One end of the swing rod 23 is rotatably connected to the swing shaft 24. The tensioning torsion spring 25 is disposed between the swing rod 23 and the swing groove 28. The swing rod 23 is obliquely disposed at the front end of the quick-release fixing bracket 2. The rotating bracket 26 is disposed at the end of the swing rod 23 away from the swing shaft 24. The tensioning roller 27 is rotatably disposed at the bottom end of the rotating bracket 26. The length of the tensioning roller 27 to the swing shaft 24 is greater than the length of the roller 3 to the swing shaft 24.

[0036] To improve the microneedle delivery effect, the tensioning roller 27 is equipped with a heating wire inside. The heating wire operates at a temperature of 40℃-65℃. The tensioning roller 27 is heated by the heating wire, which pre-heats the skin before the microneedles on the roller 3 are inserted, relaxes the skin, and can help open pores to a certain extent. This allows the microneedles to more effectively deliver active ingredients into the deeper layers of the skin, improving the treatment effect.

[0037] A tapping absorption-aiding component 29 is provided between the pre-tensioning coating component 5 and the roller 3. The tapping absorption-aiding component 29 includes a tapping swing arm 30, a tapping bracket 31, a tapping torsion spring 32, and a tapping roller 33. One end of the tapping swing arm 30 is rotatably disposed in the swing groove 28, and the tapping bracket 31 is fixedly installed at the other end of the tapping swing arm 30.

A cavity 36 is provided inside the arc-shaped cover plate 35. An array of openings 37 are arranged on the bottom wall of the cavity 36. A flexible tube is provided to connect the cavity 36 and the atomizing chamber 19.

[0038] The rolling cold compress assembly 6 includes a cold compress bracket 38 and a cold compress roller 39. The rear end of the quick-release fixed bracket 2 is provided with a sliding sleeve 40 with an opening at the bottom. The top end of the cold compress bracket 38 is provided with a sliding rod 41, which slides upward and is inserted into the sliding sleeve 40. A retaining spring 42 is provided between the top end of the sliding rod 41 and the sliding sleeve 40. The cold compress roller 39 is rotatably disposed inside the cold compress bracket 38. The top of the cold compress bracket 38 is provided with a cooling groove 43. The cooling groove 43 is provided with a semiconductor cooling chip 44 and a cooling plate 45 from the inside to the outside. The top of the cold compress roller 39 contacts the cooling plate 45. The semiconductor cooling chip 44 cools and the cooling is transferred to the cold compress roller 39 through the cooling plate 45.

[0039] The cooling support 38 is provided with a vertical groove 46, and the cooling roller 39 is provided with a rotating shaft 47 on both sides. The rotating shaft 47 is slidably disposed in the vertical groove 46, and the side wall of the rotating shaft 47 is rotatably fitted with the inner wall of the vertical groove 46. The front end of the vertical groove 46 is connected to an upwardly oriented insertion groove 48. The side of the insertion groove 48 away from the vertical groove 46 is open. The rotating shaft 47 is inserted into the vertical groove 46 through the open side of the insertion groove 48. When the microneedle beauty device moves down close to the skin, the cooling roller 39 is pushed up, thereby driving the rotating shaft 47 to move up along the vertical groove 46 and get stuck in the vertical groove 46. The open side of the insertion groove 48 is provided with an anti-detachment flexible protrusion, which can be made of rubber material.

[0040] To facilitate heat dissipation of the semiconductor cooling chip 44, the sidewall and top of the cooling support 38 are provided with heat dissipation holes 49 that communicate with the cooling tank 43.

[0041] The cooling plate 45 and the cooling roller 39 are made of titanium alloy or stainless steel.

[0042] The quick-release mounting bracket 2 is equipped with a battery 50, which is electrically connected to the atomizing plate 22, the heating wire, and the semiconductor cooling plate 44. The side wall of the handle 1 is equipped with at least three switch buttons 51, which are electrically connected to the atomizing plate 22, the heating wire, and the semiconductor cooling plate 44, respectively.

[0043] In practical use, first install the roller 3 on the quick-release mounting bracket 2, press the end cap 14 inward so that the end cap 14 retracts into the pressing groove 13, then send the roller 3 into the quick-release mounting bracket 2, then loosen the end cap 14 and move the roller 3 so that the rotating shaft 15 is aligned with the rotating groove 12. When the rotating shaft 15 is aligned with the rotating groove 12, the quick-release spring 16 pushes the end cap 14 to reset, so that the rotating shaft 15 is engaged in the rotating groove 12, completing the installation of the roller 3. Then remove the movable housing 18 of the handle 1, fill the liquid storage bottle 7 with skin care water and screw it onto the threaded mounting base 20, then reattach the movable housing 18 to the fixed housing 17. The operator holds the handle 1 and starts the atomization in advance through the switch button 51. The device consists of a plate 22, a heating wire, a semiconductor cooling plate 44, and an atomizing plate 22. The atomizing plate 22 atomizes the skincare lotion in the storage bottle 7, spraying it through the atomizing channel 21, atomizing chamber 19, and through-hole 8 onto the roller 3 and microneedle surfaces. It then sprays the lotion through the atomizing chamber 19, a flexible tube, cavity 36, and opening 37 onto the sidewall of the curved spring 34. The semiconductor cooling plate 44 cools the lotion and transfers the cooling to the cooling plate 45. The heating wire heats the tension roller 27, bringing the microneedling device closer to the patient's skin. Initially, the tension torsion spring 25 keeps the swing arm 23 swinging towards the roller 3, and the tapping torsion spring 32 keeps the tapping swing arm 30 swinging towards the roller 3. When the microneedling device approaches the patient's skin, the tension roller 27 and the tapping roller 33 first contact the patient's skin. As the microneedling device continues to approach the patient's skin, the tension roller 27 and the tapping roller 33... The tensioning roller 27 is pressed tightly against the patient's skin surface, and the quick-release fixing bracket 2 causes the tensioning roller 27 to tend to move forward, thereby tightening the patient's skin. When the microneedles on the surface of the roller 3 come into contact with the patient's skin, the tensioning roller 27 tightens the patient's skin. As the microneedling device approaches the patient's skin, the cooling roller 39 is pushed upward, thereby driving the rotating shaft 47 to move upward along the vertical slide groove 46 and lock into the vertical slide groove 46. The cooling roller 39 is also pressed against the cooling plate 45. The cooling roller 39 drives the slide rod 41 to overcome the clamping spring 42 and move upward through the cooling bracket 38, retracting into the sliding sleeve 40. When the spherical end 11 comes into contact with the patient's skin, the microneedling device is stopped from approaching the patient's skin, and the roller 3 is pushed forward to rotate along the patient's skin. The microneedles are inserted into the patient's skin. The skin-care lotion on the surface of the roller 3 and the microneedles is introduced into the skin along with the microneedles. As the roller 3 moves forward, the tension roller 27 moves forward as well, pushing the skin forward and maintaining skin taut throughout. This keeps the epidermis and dermis flat, allowing the needles to act more evenly on the target layer and temporarily reducing skin sensitivity. Especially in sensitive areas such as around the eyes and lips, moderate tension can significantly reduce pain. Before the microneedles are inserted, the heated tension roller 27 pre-applies heat to the skin, relaxing it and helping to open pores to some extent. This allows the microneedles to more effectively deliver active ingredients to the deeper layers of the skin, improving treatment efficacy. Simultaneously, the patting roller 33 rotates on the skin surface...When the arc-shaped spring 34 rotates from front to back, the arc-shaped cover 35 pushes the arc-shaped spring 34 from its root towards the side wall of the tapping roller 33. The arc-shaped spring 34 rotates from back to front within the arc-shaped cover 35. During the rotation, the atomized skin care water flows through the atomizing chamber 19, the hose, the cavity 36, and the opening 37 to the side wall of the arc-shaped spring 34. When the arc-shaped spring 34 rotates from back to front and out of the arc-shaped cover 35, the arc-shaped spring 34, under its own elastic force... The roller 33 is unfolded and moved away from the side wall of the patting roller 33, gently patting onto the patient's skin. Through the atomization of the skincare lotion and the gentle patting of the curved elastic piece 34, the absorption of the skincare lotion is accelerated. The temperature of the cooling pad 45 is transferred to the cooling roller 39. As the roller 3 moves forward, the cooling roller 39 provides real-time cooling to the skin after microneedling treatment, reducing inflammation by lowering tissue temperature. After treatment, the roller 3 is removed, and the entire device is disinfected for future use.
