Description

Technical Field

[0001] This utility model relates to the field of skin roller needle technology, and in particular to a skin roller needle with a protective sheath. Background Technology

[0002] In the field of beauty and skincare, skin rollers are a commonly used beauty tool. They use tiny needles densely packed on the roller to provide minimally invasive stimulation to the skin, prompting the skin to produce a self-repair response. At the same time, they open up skin channels, significantly increasing the skin's absorption of beauty liquids (such as serums and nutrient solutions), thereby achieving beauty effects such as skin rejuvenation, whitening, and wrinkle reduction. They are widely used in clinical and home beauty settings.

[0003] Existing skin rollers face numerous unresolved issues in packaging and transportation. On one hand, most skin roller products on the market currently use blister packs for heat-sealing, which not only requires advanced production equipment and processes but also incurs relatively high raw material and processing costs. This undoubtedly increases the overall production cost of the product, thereby affecting its price competitiveness in the market.

[0004] On the other hand, existing packaging methods are clearly inadequate in terms of needle protection. The needles of skin rollers are extremely small and sharp. During transportation, due to external forces such as bumps and compression, even when packaged in blister packs, the needles are very likely to collide and rub against the inner wall of the packaging box or other parts, resulting in damage such as bending, breakage, or blunting. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a sheathed skin roller that can effectively reduce packaging costs while ensuring product quality and providing more reliable protection for the needle.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a skin roller with a protective sleeve, including a support, a roller and a handle. The support and the handle are connected by an expansion sleeve. After the support and the handle are connected, a liquid storage cavity is formed. One end of the liquid storage cavity has a liquid outlet. The roller is installed in front of the liquid outlet and is rotatably connected to the support. The support is covered with a protective sleeve. The outer walls of the support on both sides have protrusions. The inner walls of the protective sleeve on both sides form a U-shaped fixing groove through two long and one short protrusions.

[0007] Furthermore, the inner diameter of the bracket gradually decreases from the handle towards the roller to achieve an expansion sleeve connection between the bracket and the handle.

[0008] Furthermore, a stop ring is provided on the outer periphery of the end of the handle that is connected to the bracket.

[0009] Furthermore, the bracket has a reinforcing ring on the periphery of the end connected to the handle to enhance the strength of the bracket. The distance L1 from the reinforcing ring to the end face of the bracket is the same as the distance L2 from the stop ring to the end face of the handle.

[0010] Furthermore, the roller includes a sleeve and a shaft sleeve stacked in opposite directions. An axial rectangular block is provided outside the sleeve. Roller rings and toothed rings are spaced on the sleeve. The roller rings and toothed rings are shaped to cooperate with the sleeve.

[0011] Furthermore, the handle is designed as a tapered structure with its diameter decreasing towards the support.

[0012] Furthermore, the bracket is provided with anti-slip protrusions that cooperate with the packaging body to prevent displacement during transportation.

[0013] The beneficial effects of this novel sheathed skin roller are:

[0014] 1. The innovative sheath structure, compared to traditional packaging methods, not only reduces material waste and labor costs during production and minimizes space occupation during warehousing and transportation, but also provides more reliable protection for the needles. During product transportation and storage, the sheath can effectively prevent the needles from colliding and rubbing against external objects, preventing damage, deformation, or breakage of the needle tip. At the same time, it isolates dust, bacteria, and other contaminants, ensuring that the needles are clean and sterile, greatly improving product safety and reliability.

[0015] 2. The sheath design balances protection and ease of use. Medical staff or users can easily open the sheath and quickly access the roller needle through a simple and convenient operation. The operation process is smooth, reducing access time and improving work efficiency.

[0016] 3. The sheath structure is tightly and securely connected to the needle roller body, maintaining good protection even in complex environments such as bumps and vibrations. The sheath will not easily fall off or be damaged, ensuring that the needle roller is always in a safe and protected state throughout the entire circulation process, thus extending the effective shelf life of the product.
