Description

Technical Field

[0001] This invention provides a microneedle roller for beauty care, belonging to the field of microneedle roller technology. Background Technology

[0002] As living standards continue to improve, women's demands for quality of life are also increasing, especially in skincare and cosmetics. Skincare has gradually become a daily routine for most modern women. However, most skincare serums are slowly absorbed by the skin, and many active ingredients remain on the skin's surface, resulting in low transdermal absorption. Microneedling rollers have emerged to address this need. These rollers have a rotating section with numerous microneedles. When used, the roller is pressed against the skin, and the microneedles stimulate the skin, creating numerous microchannels on the skin's surface in a very short time, allowing active ingredients to effectively penetrate the skin.

[0003] Existing microneedle rollers can basically meet the needs of normal beauty care. They mainly include a handle, a connecting frame, rollers set between the connecting frame, and multiple microneedles evenly spaced on the roller surface. In use, the rollers are engaged in locking holes on the side walls of the connecting frame via rotating shafts on both sides. When it is necessary to replace the roller with one containing microneedles of different lengths or to clean the roller, it is usually necessary to forcefully pry the support outwards to create a gap between the rotating shaft and the locking hole, and then forcefully remove the roller from between the connecting frame. This disassembly and assembly is inconvenient, time-consuming, and laborious. Moreover, prying the support outwards is very easy to damage, and the effectiveness needs improvement. Therefore, this utility model provides a microneedle roller for beauty care. Utility Model Content

[0004] The technical problem solved by this utility model is that the roller with microneedle tip is not convenient to disassemble and assemble, which is relatively time-consuming and laborious, and the bracket is very easy to be damaged when it is pried outward, so the effect of use needs to be improved.

[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a microneedle roller for beauty care, including a handle, a connecting plate at the head end of the handle, supports on both sides of the connecting plate, a reset assembly between the connecting plate and the supports, a removable roller rotatably connected between the supports, and multiple microneedles on the roller; the reset assembly includes symmetrically opened grooves on the side wall of the connecting plate, a sliding plate slidably connected in the groove, a reset spring between the inner side wall of the groove and one side wall of the sliding plate, and a pull rod fixedly connected to the support on the other side wall of the sliding plate.

[0006] Furthermore, the handle is made of PC material, and the surface of the handle is treated with an anti-slip coating.

[0007] Furthermore, the microneedles are made of food-grade stainless steel, and multiple microneedles are arranged neatly and at equal intervals.

[0008] Furthermore, the corners of the connecting plate and the bracket are rounded and blunted.

[0009] Furthermore, the roller has a rotating shaft passing through the bracket on both sides, the bracket has a through hole matching the rotating shaft, and the rotating shaft has a stop block that fits against the inner side wall of the bracket.

[0010] Furthermore, the inner sidewall of the slide is symmetrically provided with limiting rails that match the slide plate, and the limiting rails are provided with limiting stops at both ends.

[0011] The beneficial effects of this utility model are:

[0012] Through the combined action of the reset components, the outward-moving bracket drives the pull rod and slide plate to move outward, allowing the rotating shaft to move out of the through hole. This makes it easy to remove the original roller. Then, the bracket is moved outward in the same way, placing the new roller between the brackets and ensuring that the rotating shaft is connected to the through hole. When the bracket is released, the tensioned reset spring rebounds and resets, causing the bracket to rebound and reset. The rotating shaft passes through the through hole, and the inner wall of the bracket fits against the side wall of the stop block, making it easy to install the new roller. Compared to the traditional method of clamping the roller between the brackets, this method is more convenient to install and remove, saving time and effort. It effectively prevents damage caused by the bracket being pried outward, greatly improving the performance. Attached Figure Description

[0021] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] According to the appendix Figure 1 , 2 As shown in Figures 3 and 4: This utility model provides a microneedle roller for beauty care: it includes a handle 1, which is made of PC material and has an anti-slip surface for easy grip. A connecting plate 2 is provided at the head of the handle 1, and supports 3 are provided on both sides of the connecting plate 2. The corners of the connecting plate 2 and supports 3 are rounded to prevent sharp edges from scratching the user. A detachable roller 5 is rotatably connected between the supports 3. Multiple microneedles 6 are provided on the roller 5. The microneedles 6 are made of food-grade stainless steel and are arranged neatly and evenly. The microneedle 6 has a length of 0.3-1.5mm. The roller 5 has a rotating shaft 11 that passes through the support 3 on both sides. The support 3 has a through hole 12 that matches the rotating shaft 11. The shaft of the rotating shaft 11 has a stop 13 that fits against the inner side wall of the support 3. The stop 13 can limit the rotation shaft 11 so that it is placed in the through hole 12. When the roller 5 is pressed on the skin surface, the microneedle 6 stimulates the skin. In a very short time, the microneedle can create a large number of microchannels on the skin surface, allowing the active ingredients to effectively penetrate the skin for beauty care.

[0023] As per the instruction manual Figure 1 , 5As shown: A reset assembly 4 is provided between the connecting plate 2 and the bracket 3. The reset assembly 4 includes a sliding groove 7 symmetrically opened on the side wall of the connecting plate 2. A sliding plate 8 is slidably connected in the sliding groove 7. A limiting rail 14 matching the sliding plate 8 is symmetrically provided on the inner side wall of the sliding groove 7 to limit the movement. Limiting stops 15 are provided at both ends of the limiting rail 14 to prevent the sliding plate from moving off the limiting rail 14. A reset spring 9 is provided between the inner side wall of the sliding groove 7 and one side wall of the sliding plate 8. A pull rod 10 fixedly connected to the bracket 3 is provided on the other side wall of the sliding plate 8. Moving the bracket 3 outward will drive the pull rod 10 and the sliding plate 8 to move outward, thereby causing the reset spring 9 to be stretched. After the bracket 3 moves outward a certain distance, the rotating shaft 11 will move out of the through hole 12, which can easily remove the roller 5.

[0024] The principle of this utility model

[0025] In use, the roller 5 is pressed against the skin surface, and the microneedle 6 stimulates the skin for beauty care. When it is necessary to replace the roller 5 with a roller 5 of a different length or to clean the roller 5, the bracket 3 is moved outward, which drives the pull rod 10 and the slide plate 8 to move outward. This causes the return spring 9 to be stretched. After the bracket 3 moves outward a certain distance, the rotating shaft 11 moves out of the through hole 12, making it easy to remove the original roller 5. Then, the bracket 3 is moved outward in the same way, and the new roller 5 is placed between the brackets 3, so that the rotating shaft 11 is connected to the through hole 12. When the bracket 3 is released, the stretched return spring 9 rebounds and resets, causing the bracket 3 to rebound and reset. The rotating shaft 11 passes through the through hole 12, and the inner side wall of the bracket 3 fits against the side wall of the stop block 13, making it easy to install the new roller 5. Compared with the traditional method of clamping the roller between the brackets 3, it is easier to disassemble and assemble, saves time and effort, effectively avoids damage caused by bending the bracket 3 outward, and greatly improves the effect of use.
