Description

Technical Field

[0001] This utility model relates to the field of cosmetic medical devices, specifically to a liquid-filling type microcrystalline roller. Background Technology

[0002] Nanocrystal wafers are widely used in the medical and cosmetic industries. Their surface consists of a series of microneedles that can open the outermost layer of skin, the stratum corneum, without damaging the dermis, greatly improving nutrient penetration. However, most nanocrystal products on the market use vibration as their operating mechanism, making them cumbersome to use with instruments. Products that use manual pressing (such as the modular penetration enhancer CN216456514U) require user pressing, resulting in a less than ideal user experience.

[0003] Meanwhile, most commercially available needle rollers use stainless steel needles, which often cause pain and a poor user experience. Although devices that allow medication to be directly dripped onto the needle roller surface have emerged, their uniformity and operability are significantly compromised. Therefore, the market urgently needs a nanocrystalline needle roller product that allows for direct medication application, is easy to operate, and provides a superior user experience. Utility Model Content

[0004] This invention provides a liquid-filling type microcrystalline needle roller to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A liquid-filling microcrystalline roller needle includes a microcrystalline roller body and a handle body. The microcrystalline roller body includes a roller movably connected to the handle body, a plurality of nanocrystalline particles connected in the circumferential direction of the roller, and an outer cover connected to one end of the handle body. The outer wall of the roller in the circumferential direction has a plurality of roller liquid outlet holes communicating with the inner cavity of the roller. Each of the plurality of nanocrystalline particles has a through-hole for liquid outlet. The liquid outlet holes on the nanocrystalline particles correspond one-to-one with the liquid outlet holes on the roller. The microcrystalline roller body has a liquid filling hole for injecting liquid into the inner cavity of the roller, and a plug for sealing is provided in the liquid filling hole.

[0007] Preferably, one end of the roller is provided with a mounting position, and the outer cover and the mounting position of the roller are connected by any one of interference fit, threaded fit, adhesive bonding or ultrasonic welding.

[0008] Preferably, the roller has multiple mounting areas in the circumferential direction, each mounting area having a microcrystalline bonding surface, and multiple nanocrystalline materials are bonded to the corresponding microcrystalline bonding surface on the roller by adhesive.

[0009] Preferably, the liquid outlet hole of the roller is located at the microcrystalline bonding surface and communicates with the inner cavity of the roller.

[0010] Preferably, the thickness of the nanocrystals is greater than the depth of the mounting area.

[0011] Preferably, one end of the roller is provided with a roller end shaft, and one side of the outer cover is provided with an outer cover end shaft. The microcrystalline roller body is movably connected to the handle body through the roller end shaft and the outer cover end shaft.

[0012] Preferably, the outer cover end shaft and the roller end shaft are coaxially arranged.

[0013] Preferably, the liquid filling hole is opened through one end of the roller, and the liquid filling hole corresponds to the outer cover.

[0014] Preferably, the liquid filling hole is formed through the surface of the outer cover.

[0015] Preferably, the handle body includes an integrally formed handle portion and a connecting portion, and the microcrystalline roller body is movably connected to the connecting portion.

[0016] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0017] In this invention, by removing the plug, the medicine can be injected into the inner cavity of the roller through the filling hole. After the filling is completed, the plug ensures the sealing of one end of the roller. Furthermore, by holding the handle and rolling the microcrystalline roller, the user can make the medicine flow through the liquid outlet holes of the roller and the microcrystalline liquid outlet holes to the skin.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] Example 1

[0030] like Figures 1-3 As shown, this utility model provides a liquid-filling microcrystalline roller needle, including a microcrystalline roller body 1 and a handle body 2. The microcrystalline roller body 1 includes a roller 12 movably connected to the handle body 2, a plurality of nano-microcrystals 11 connected in the circumferential direction of the roller 12, and an outer cover 13 connected to one end of the handle body 2. The outer wall in the circumferential direction of the roller 12 is provided with a plurality of roller liquid outlet holes 122 communicating with the inner cavity of the roller 12. Each of the plurality of nano-microcrystals 11 is provided with a microcrystalline liquid outlet hole 111. The microcrystalline liquid outlet hole 111 on the nano-microcrystal 11 corresponds one-to-one with the roller liquid outlet hole 122 on the roller 12. The microcrystalline roller body 1 is provided with a liquid filling hole 131 for injecting liquid into the inner cavity of the roller 12. A plug 14 for sealing is provided in the liquid filling hole 131. The handle body 2 includes an integrally formed handle and a connecting part. The microcrystalline roller body 1 is movably connected to the connecting part.

[0031] It is worth noting that the nanocrystals 11 can be a single crystal, a row of multiple crystals, an array of multiple rows, or even a number of irregularly arranged pores, which mainly ensure the outflow of the medicine inside the roller 12.

[0032] Combination Figure 2 and Figure 3 As shown, as a further step, one end of the roller 12 is provided with a mounting position 124, and the outer cover 13 and the mounting position 124 of the roller 12 are connected by any one of interference fit, threaded fit, adhesive bonding or ultrasonic welding.

[0033] Specifically, the cross-sectional view of the outer cover 13 is "T" shaped. The "T" shaped outer cover 13 can ensure the stability of the connection with the roller 12. It is worth noting that when the outer cover 13 is connected to one end of the roller 12, those skilled in the art can install a sealing ring according to the actual situation to effectively improve the sealing between the roller 12 and the outer cover 13.

[0034] Combination Figure 2 As shown, as a further step, the roller 12 is provided with multiple installation areas in the circumferential direction. Each installation area has a microcrystalline adhesive surface 121, and multiple nano-microcrystals 11 are bonded to the corresponding microcrystalline adhesive surface 121 on the roller 12 by adhesive. The roller liquid outlet hole 122 is opened at the microcrystalline adhesive surface 121 and communicates with the inner cavity of the roller 12. The thickness of the nano-microcrystals 11 is greater than the depth of the installation area.

[0035] Specifically, there are at least three installation areas, and in actual production, there are not limited to three. Therefore, the synchronous corresponding setting of nano-microcrystals 11 ensures that the more nano-microcrystals there are, the closer the outer wall of the roller 12 will be to a circle, thus making the experience of liquid-filled microcrystalline needle rollers better.

[0036] Combination Figure 3 As shown, as a further step, one end of the roller 12 is provided with a roller end shaft 123, and one side of the outer cover 13 is provided with an outer cover end shaft 132. The microcrystalline roller body 1 is movably connected to the handle body 2 through the roller end shaft 123 and the outer cover end shaft 132, and the outer cover end shaft 132 is coaxially arranged with the roller end shaft 123.

[0037] Specifically, through the design of the outer cover end shaft 132 and the roller end shaft 123, the microcrystalline roller body 1 can rotate when the handle body 2 pushes the microcrystalline roller body 1, ensuring that the nano-microcrystals 11 set around the circumference are conducive to the penetration and application of the medicine. It is highly practical, has a better user experience, and saves time and effort compared to existing press-type products.

[0038] Combination Figure 3 As shown, as a further step, a liquid filling hole 131 is formed through the surface of the outer cover 13, and a plug 14 is disposed inside the liquid filling hole 131.

[0039] Example 2

[0040] This embodiment is basically the same as the first embodiment in structure, except that the liquid filling hole 131 is opened through one end of the roller 12 and the liquid filling hole 131 corresponds to the outer cover 13. The plug 14 is set in the liquid filling hole 131. This structure is not shown in the figure, but it is well known to those skilled in the art. Therefore, it is convenient for the user to pour the medicine into the inner cavity of the roller 12 through the liquid filling hole 131 to complete the liquid filling work.

[0041] The working principle and usage process of this utility model are as follows: First, the stopper 14 needs to be pulled out from the plugged position of the liquid filling hole 131. Then, the medicine to be applied is poured into the liquid filling hole 131, allowing the medicine to flow into the inner cavity of the roller 12 along the liquid filling hole 131. After the liquid filling is completed, the stopper 14 can be inserted into the liquid filling hole 131 to ensure a seal. Then, the user can hold the handle of the main body 2 and roll the microcrystalline roller body 1, causing the medicine to flow out through the roller outlet hole 122 and the microcrystalline outlet hole 111, ensuring that the medicine reaches the skin. This facilitates the application and penetration of the microcrystalline roller body 1 to the operating area. Compared with press-type products, this method saves time and effort, and provides a better user experience. Moreover, this solution only requires filling the medicine to complete all preparations, making the operation simple and quick.

[0042] It should be noted that the opening of the roller liquid outlet 122 and the microcrystalline liquid outlet 111 is not as large as shown in the figure during actual processing, so as not to cause a large amount of reagent to flow out and be wasted. The attached figure of this solution is drawn for the roller liquid outlet 122 and the microcrystalline liquid outlet 111 for easier understanding and viewing.
