[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The present application embodiment discloses a microcrystalline roller. Figure 1 , Figure 2 and Figure 3 The microcrystalline roller comprises a handle 1, a massage roller 2 and a soluble microneedle patch 3. A 7-shaped mounting portion 4 is provided at one end of the handle 1, a rotation hole 211 is provided at one end of the massage roller 2 along its axis, an end of the 7-shaped mounting portion 4 away from the handle 1 is inserted into the rotation hole 211, and the massage roller 2 and the 7-shaped mounting portion 4 can be detachably and rotatably assembled (i.e. Figure 2 The diameter of the rotating shaft 42 is slightly smaller than the inner diameter of the rotating hole 211), the soluble microneedle patch 3 includes a cylindrical substrate 31 and a plurality of microneedles 32, the substrate 31 is sleeved and bonded to the outer peripheral wall of the massage roller 2, and adjacent microneedles 32 are arranged at intervals on the outer peripheral wall of the substrate 31.

[0036] The beneficial technical effects of the microcrystalline roller of the embodiment of the present application are roughly as follows:

[0037] Compared with the fork portion of the common U-shaped structure, the 7-shaped mounting portion 4 is an open design, and can be adapted to massage rollers 2 of different lengths. It is not easy to have the problem that the massage roller 2 cannot be stably installed due to being too long or too short. Moreover, the 7-shaped mounting portion 4 can provide quick plug-in connection for the massage roller 2, and assembly, disassembly and replacement are more convenient and quick.

[0038] In this embodiment, the 7-shaped mounting portion 4 includes a bent bracket 41 and a shaft 42. The shaft 42 is perpendicular to the length direction of the handle 1 and is used to fit into the rotating hole 211. The length of the shaft 42 extending into the rotating hole is at least half of the length of the massage roller 2.

[0039] In order to further facilitate the quick assembly of the rotating shaft 42 and the massage roller 2 , a conical slope 421 is provided at the outer end of the rotating shaft 42 . The conical slope 421 is used to form a guide surface for the rotating shaft 42 to be quickly aligned and inserted into the rotating hole 211 .

[0040] When installing the massage roller 2 , in order to prevent the massage roller 2 from being assembled excessively, a blocking ring 422 is further provided on the outer peripheral wall of the rotating shaft 42 , and the blocking ring 422 is used to block the outer end surface of the massage roller 2 .

[0041] In order to prevent the massage roller 2 from slipping off the rotating shaft 42, an annular limiting groove 212 is provided on the inner peripheral wall of the rotating hole 211, and a circle of hemispherical convex bumps 423 arranged at intervals are provided on the outer peripheral wall of the rotating shaft 42. The hemispherical convex bumps 423 are used to be inserted into the annular limiting groove 212. The annular limiting groove 212 has a certain limiting effect on the hemispherical convex bumps 423. Of course, when using greater force to pull out the massage roller 2, the hemispherical convex bumps 423 can slide out of the annular limiting groove 212.

[0042] Furthermore, in order to prevent the corners of the 7-shaped mounting portion 4 from being too sharp and hurting human skin, the bending portion of the bending bracket 41 is an arc-shaped transition structure, and the connection between the bending bracket 41 and the rotating shaft 42 is an arc-shaped transition structure.

[0043] The 7-shaped mounting portion 4 designed above has a simple and firm structure, is easy to manufacture, and has a relatively low manufacturing cost.

[0044] In this embodiment, the massage roller 2 includes an inner cylinder 21 and a rubber sleeve 22. The rubber sleeve 22 is fixed on the inner cylinder 21. The base plate 31 is bonded to the outer wall of the rubber sleeve 22. The rubber sleeve 22 has a certain elasticity. When the massage roller 2 is rolled on the skin, the microneedles 32 can fit the skin surface more closely and the comfort of use can be significantly improved.

[0045] In order to prevent the soluble microneedle patch 3 from slipping off the inner tube 21 and to protect the soluble microneedle patch 3 from impact to a certain extent, baffles 213 are provided at both ends of the inner tube 21. The two baffles 213 block the two ends of the rubber sleeve 22 and the two ends of the substrate 31.

[0046] In order to facilitate the manufacture and assembly of the 7-shaped mounting portion 4 , the 7-shaped mounting portion 4 can be detachably mounted on the handle 1 , and the mounting method of the 7-shaped mounting portion 4 is: plug-in, threaded connection or clamping.

[0047] In a feasible technical solution of the present application, the handle 1 and the 7-shaped mounting portion 4 are made of hard metal material or hard plastic material, and the above materials have relatively high hardness and strength and are not easily damaged during use.

[0048] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the application should be included in the protection scope of the present application.
