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

[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The present application discloses an easily replaceable wheel soluble microneedle massager. Figure 1 、 Figure 2 and Figure 3 The easy-to-change wheel soluble microneedle massager 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 with each other. The two fork plates 11 are provided with correspondingly arranged pin holes. An improved pin shaft 4 is detachably inserted between the two pin holes. A rotating through hole 211 is provided along the central axis of the massage roller 2. The improved pin shaft 4 penetrates the two pin holes and the rotating through hole 211, and the massage roller 2 can rotate freely after being penetrated by the improved pin shaft 4.

[0031] The beneficial technical effects of the easily replaceable wheel soluble microneedle massager of the embodiment of the present application are roughly as follows:

[0032] By adding an improved pin shaft 4 with a detachable plug-in assembly, the installation and removal of the massage roller 2 are facilitated, and the rotation through hole 211 on the massage roller 2 is combined to achieve smooth rotation between the improved bolt member and the massage roller 2. The above structural design changes the traditional clip-on 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, which effectively prevents the massage roller 2 from loosening or even falling, and provides a better user experience.

[0033] In this embodiment, the improved pin shaft 4 includes a shaft rod 41 and a limiting cap 42. The limiting cap 42 is fixedly connected to the outer end of the shaft rod 41. The length of the shaft rod 41 is equal to the distance between the outer sides of the two fork plates 11. The diameter of the shaft rod 41 is 0.01-0.03 mm smaller than the diameter of the rotating through hole 211. Anti-slip grooves are provided on the peripheral side walls of the limiting cap 42.

[0034] The improved pin shaft 4 is an integrally molded plastic part, the shaft 41 is a hollow tubular structure, a plurality of groups of first magnets 43 are arranged in the shaft 41, and a magnetic sleeve 213 made of ferromagnetic material is arranged in the rotating through hole 211. The magnetic sleeve 213 and the first magnet 43 are arranged correspondingly, and the magnetic sleeve 213 is located at the bottom of the bell mouth 214. The magnetic attraction between the magnetic sleeve 213 and the first magnet 43 is used to prevent the massage roller 2 from axial sliding without affecting the free rotation of the massage roller 2.

[0035] The improved pin 4 of the above design has a simple and durable structure, low manufacturing cost, is easy to install and disassemble, and is not prone to slipping when screwing. The design of the shaft 41 cooperates with the rotating through hole 211 to achieve the purpose of silky rotation of the massage roller 2. In addition, the added magnetic sleeve 213 and the first magnet 43 cooperate with each other to effectively prevent the massage roller 2 from easily sliding axially.

[0036] In this embodiment, in order to facilitate the insertion of the shaft rod 41 , both ends of the rotating through hole 211 are provided with bell mouths 214 for facilitating the alignment and insertion of the shaft rod 41 . The bell mouths 214 are truncated cone structures.

[0037] In this embodiment, the fork plate 11 is a plastic part, and a through hole is provided on the fork plate 11, and a stainless steel sleeve 12 is interference fitted in the through hole. The pin hole is formed on the inner circumferential wall of the stainless steel sleeve 12, and two groups of second magnets 44 are also provided in the shaft 41. The second magnet 44 and the stainless steel sleeve 12 are magnetically fixed. The design of the stainless steel sleeve 12 can make the fork plate 11 more durable, and the magnetic combination of the stainless steel sleeve 12 and the second magnet 44 is conducive to preventing the improved pin shaft 4 from loosening and falling.

[0038] 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, and a rotational through-hole 211 is formed within 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.
