Description

Technical Field

[0001] The present application relates to the technical field of microneedle application devices, and in particular to a soluble microneedle massage roller. Background Art

[0002] The microneedle massage stick uses many tiny needles on the microneedle roller to stimulate the skin and allow active ingredients to penetrate the skin effectively.

[0003] After searching, the Chinese patent with application number: 202120956489.5 discloses a soluble microneedle massage stick, which includes a handle, a massage roller and a soluble microneedle patch. A fork portion is provided at one end of the handle, and the massage roller is rotatably installed on the fork portion. The soluble microneedle patch includes a substrate and microneedles, and the substrate is bonded to the outer peripheral wall of the massage roller, wherein the massage roller is detachably installed on the fork portion mainly by snapping.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved:

[0005] Although the snap-on method can facilitate the quick installation and removal of the massage roller, during the installation and removal of the massage roller, it is necessary to use strong force to pry open the fork part and make the opening width of the fork part a little larger. Improper operation can easily cause the fork part to deform and transition, and the massage roller may easily fail to clamp or even fall off in the later stage. Utility Model Content

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The present application discloses a soluble microneedle massage roller. Figure 1 and Figure 2 The soluble microneedle massage roller includes a handle 1, a massage roller 2 and a soluble microneedle patch 3. The soluble microneedle patch 3 is adhered to the outer peripheral wall of the massage roller 2. One end of the handle 1 is provided with two fork plates 11 arranged in parallel at intervals. A notch 111 is provided on the top of the fork plate 11 to form an elastic clamping structure. A rotating shaft 23 is provided at both ends of the massage roller 2 along the central axis. The rotating shaft 23 is detachably connected to the bottom of the notch 111. A mounting groove 113 is also provided on the top of the fork plate 11. A U-shaped locking buckle 4 is detachably clamped in the mounting groove 113. The U-shaped locking buckle 4 clamped in the mounting groove 113 is used to drive the opening of the notch 111 to retract inward. The rotating shaft 23 clamped in the notch 111 can rotate freely. A circular arc transition portion 24 is provided at the connection between the rotating shaft 23 and the side end of the massage roller 2. The circular arc transition portion 24 can enhance the structural firmness between the two.

[0030] The beneficial technical effects of the soluble microneedle massage roller of the embodiment of the present application are roughly as follows:

[0031] By adding a notch 111 on the fork plate 11 for adapting the rotating shaft 23, the installation and disassembly of the massage roller 2 is facilitated, and the smooth rotation of the massage roller 2 can be ensured. Combined with the U-shaped locking buckle 4 that can be detachably assembled on the fork plate 11, the rotating shaft 23 is effectively prevented from easily escaping from the notch 111. The above structural design changes the traditional card-connecting assembly method of the massage roller 2. On the basis of easy installation and disassembly, the structure is also stable and durable, and it is not easy to cause deformation and transition of the two fork plates 11, effectively preventing the massage roller 2 from loosening or even falling, and providing a better user experience.

[0032] In this embodiment, in order to better adapt to the rotation space required by the rotating shaft 23 and ensure the smooth rotation of the massage roller 2, a circular rotating hole 112 is provided at the bottom of the notch 111, and the rotating shaft 23 is connected to the circular rotating hole 112. The width of the notch 111 is smaller than the diameter of the circular rotating hole 112.

[0033] Taking into account aspects such as controlling costs and improving product life, the fork plate 11 is a plastic part, the U-shaped locking buckle 4 is a stainless steel part, and a convex arc surface 41 is provided on the top of the U-shaped locking buckle 4. The design of the convex arc surface 41 can effectively prevent the top corners of the fork plate 11 from hurting people, making it safer.

[0034] In order to ensure the integrity and firmness of the fork plate 11 after the U-shaped locking buckle 4 is installed, the thickness of the U-shaped locking buckle 4 is consistent with the depth of the installation groove 113. The installation groove 113 is located in the middle of the thickness direction of the fork plate 11, and the thickness of the fork plate 11 is 2-3 times the width of the installation groove 113.

[0035] In this embodiment, the massage roller 2 comprises an inner cylinder 21 and a rubber sleeve 22. The rubber sleeve 22 is fixedly mounted on the inner cylinder 21. The soluble microneedle patch 3 is adhered to the outer wall of the rubber sleeve 22. The rotating shaft 23 is integrally formed with the inner cylinder 21. The rubber sleeve 22 has a certain degree of elasticity. When the massage roller 2 is rolled over the skin, the soluble microneedle patch 3 conforms more closely to the skin surface, significantly improving the comfort of use.

[0036] In order to prevent the soluble microneedle patch 3 from tilting when pasting, baffle rings 212 are provided at both ends of the inner cylinder 21. The baffle rings 212 are used to block the two sides of the soluble microneedle patch 3, and the two baffle rings 212 have a good protective effect on the soluble microneedle patch 3 in the middle.

[0037] In this embodiment, the soluble microneedle patch 3 includes an integrally formed substrate 31 and a needle tip portion 32. The substrate 31 is bent into a cylindrical shape, and multiple needle tip portions 32 are arranged in a row on the outer wall of the substrate 31. The length direction of the needle tip portion 32 is arranged along the inner diameter direction of the cylindrical substrate 31.

[0038] The soluble microneedle patch 3 of the above design can be in the form of a flat sheet before being bonded to the massage roller 2, which is convenient for manufacturing and die-cutting into a square shape of a preset size, thereby reducing the manufacturing and assembly costs to a certain extent.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the application should be included in the scope of protection of the present application.
