Description

Technical Field

[0001] This application relates to the field of nail tool technology, and in particular to a nail grinding head with a segmented groove structure. Background Technology

[0002] In the field of nail art tools, the nail polishing head is a core tool, and its performance directly affects the efficiency and effect of nail treatment. Nail polishing heads typically connect quickly to nail filing machines via a handle structure, using the rotational power provided by the filing machine to finely polish dead skin, cuticles, and the nail surface.

[0003] Currently, to meet the requirements for polishing precision and sharpness in the pre-treatment of nail art, nail polishing heads with a cross-groove structure and diamond particles attached by electroplating are usually used. These nail polishing heads can quickly cut the nail cuticle layer, effectively improve polishing efficiency, and ensure the flatness and smoothness of the nail surface after treatment. They are widely used in professional nail art scenarios.

[0004] However, existing pre-treatment nail polishing heads still have significant performance shortcomings in actual use. Due to the complex groove design of the cross-grooves, the skin flakes generated during polishing are difficult to remove in time, causing them to accumulate on the polishing head and affecting the subsequent polishing effect, which requires improvement. Utility Model Content

[0005] To address the problem of poor chip removal in existing pre-treatment nail polishing heads during use, this application provides a nail polishing head with a segmented groove structure.

[0006] This application provides a nail polishing head with a segmented groove structure, which adopts the following technical solution: A nail polishing head with a segmented groove structure includes a blade holder and an integrally formed polishing head disposed at one end of the blade holder. The polishing head is arranged in sequence along its axial direction as a front grinding section and a chip removal section, and both the front grinding section and the chip removal section are provided with a diamond layer.

[0007] By adopting the above technical solution, the blade holder and the grinding head are integrally molded to ensure rigidity and stability during high-speed rotation. The diamond layer on the front grinding part can improve sharpness, enabling the front grinding part to quickly process delicate areas such as the nail cuticle during the pre-treatment of nail art. The chip removal part can work with the front grinding part to quickly remove the chips generated during the grinding process. While ensuring grinding accuracy and sharpness, it significantly improves chip removal efficiency, solving the core problem of poor chip removal in existing nail grinding heads. The chip removal part is also equipped with a diamond layer, so that the chip removal part can play an auxiliary role in grinding.

[0008] Preferably, a left helical groove and a right helical groove are formed on the outer surface of the front grinding part. The left helical groove and the right helical groove intersect each other to form a cross groove, and a grinding tooth is formed at the intersection of any left helical groove and the right helical groove. The diamond layer on the front grinding part is disposed on the inner wall of the cross groove and the outer surface of the grinding tooth.

[0009] By adopting the above technical solution, the left and right spiral grooves on the outer surface of the front grinding part intersect to form a cross groove. The cross groove design allows the front grinding part to disperse grinding stress when grinding nails, making grinding more stable. At the same time, the grinding teeth formed at the intersection of the cross grooves increase the number of cutting edges. The diamond layer is set on the inner wall of the cross groove and the outer surface of the grinding teeth, so that the diamond particles are evenly distributed on the cutting edges of the grinding teeth, thereby significantly improving the sharpness of the grinding teeth and enabling rapid processing of delicate areas such as the nail cuticle.

[0010] Preferably, a continuous spiral groove is formed on the outer surface of the chip removal part, and a shielding adhesive layer is provided in the continuous spiral groove to form an embedded fit with it. The protrusion between the continuous spiral grooves is set as an auxiliary grinding part, and the diamond layer on the chip removal part is disposed on the outer surface of the auxiliary grinding part.

[0011] By adopting the above technical solution, a shielding adhesive layer is set inside the continuous spiral groove to prevent diamond particles from covering the inside of the groove, ensuring that the inner wall of the continuous spiral groove is smooth. With the specific spiral angle design, the skin chips generated during the polishing process can be discharged in a directional manner along the spiral direction, solving the problem of poor chip removal in existing nail polishing heads and improving chip removal efficiency. The protrusions between the continuous spiral grooves are set as auxiliary grinding parts and a diamond layer is set on their outer surface, which can assist the front grinding part in polishing the hard skin on both sides of the nail, further improving the overall polishing effect.

[0012] Preferably, the cross groove is connected to one end of the continuous spiral groove.

[0013] By adopting the above technical solution, the cross groove and the continuous spiral groove can be connected to form a through air circulation channel, increase the heat dissipation area, avoid the grinding head temperature from getting too high during continuous use, and extend the service life of the grinding head. At the same time, the connection between the cross groove and the continuous spiral groove helps the chips to be discharged from the cross groove to the continuous spiral groove, further improving the chip removal efficiency.

[0014] Preferably, a reinforcing transition portion is provided at the connection between the grinding head and the tool holder, and the outer diameter of the reinforcing transition portion gradually increases in the direction away from the grinding head.

[0015] By adopting the above technical solution, a reinforced transition section is set at the connection between the grinding head and the blade holder, and its outer diameter gradually increases in the direction away from the grinding head. This can effectively disperse the stress generated during grinding, enhance the structural strength and stability of the connection between the grinding head and the blade holder, reduce the risk of breakage at the connection, and extend the service life of the nail polishing head.

[0016] Preferably, the tool holder is provided with a specification marking ring for distinguishing different specifications of grinding heads.

[0017] By adopting the above technical solution and setting a specification marking ring on the blade holder, users can quickly distinguish between different specifications of grinding heads, making it more convenient and efficient for users to select and replace nail grinding heads, reducing usage errors caused by specification confusion, and improving the professionalism and convenience of nail art operations.

[0018] Preferably, the blade is provided with a protective component to prevent skin flakes from entering the interior of the nail polishing machine.

[0019] By adopting the above technical solution, protective components can be installed on the blade bar to prevent skin flakes from entering the nail polishing machine, thus avoiding skin flakes affecting the normal operation and service life of the machine, protecting the internal parts of the nail polishing machine from contamination and damage, reducing machine maintenance costs, and ensuring the stable operation of the nail polishing machine.

[0020] Preferably, the protective component is fixed to the nail polishing machine near the nail polishing machine with the blade as the axis, the protective component is umbrella-shaped, and the protective component is open and facing the nail polishing machine.

[0021] By adopting the above technical solution, the umbrella-shaped protective component has a larger shielding range, which can more comprehensively block the movement of skin flakes towards the nail polishing machine. At the same time, the umbrella-shaped structure will not interfere with the normal rotation and use of the polishing head. The design of the opening facing the nail polishing machine further enhances the guiding and interception effect of skin flakes, making it impossible for skin flakes to bypass the protective component and enter the machine.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The grinding head includes a front grinding section and a chip removal section. The front grinding section is equipped with cross grooves to disperse grinding stress and make grinding more stable. At the same time, the grinding teeth formed at the intersection of the cross grooves increase the number of cutting edges. Combined with the diamond layer, the sharpness is improved, which can quickly process delicate areas such as the cuticle of the nail. The chip removal section is equipped with continuous spiral grooves and a shielding adhesive layer inside the grooves to ensure that the inner wall of the continuous spiral grooves is smooth. This allows the chips generated during the grinding process to be discharged in a spiral direction. Meanwhile, the protrusions between the continuous spiral grooves are set as auxiliary grinding sections and are equipped with a diamond layer on their outer surface. This can assist the front grinding section in grinding the hard skin on both sides of the nail, further improving the overall grinding effect. 2. The cross groove is connected to the continuous spiral groove at one end, forming a through air circulation channel, increasing the heat dissipation area, avoiding excessive temperature of the grinding head during continuous use, and extending the service life of the grinding head. At the same time, the connection between the cross groove and the continuous spiral groove helps the chips to be discharged from the cross groove to the continuous spiral groove, further improving chip removal efficiency. 3. The protective component on the blade bar prevents skin flakes from entering the nail file machine, thus avoiding them from affecting the machine's normal operation and lifespan. The umbrella-shaped design of the protective component can more comprehensively block skin flakes from moving towards the nail file machine. At the same time, the umbrella-shaped structure will not interfere with the normal rotation and use of the file head. The design with the opening facing the nail file machine further enhances the guiding and interception effect of skin flakes, making it impossible for skin flakes to bypass the protective component and enter the machine.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0026] This application discloses a nail polishing head with a segmented groove structure.

[0027] Reference Figure 1 and Figure 2A nail polishing head with a segmented groove structure includes a blade shank 1 and a polishing head 2 integrally formed and fixed to one end of the blade shank 1. In this embodiment, the polishing head 2 is torch-shaped. The polishing head 2 is arranged in sequence along its axial direction as a front grinding section 21 and a chip removal section 22. The length of the front grinding section 21 accounts for one-quarter to one-third of the length of the entire polishing head 2. Both the front grinding section 21 and the chip removal section 22 are coated with a diamond layer 3 by electroplating. A reinforcing transition section 11 is integrally formed at the connection between the polishing head 2 and the blade shank 1, and the outer diameter of the reinforcing transition section 11 gradually increases in the direction away from the polishing head 2.

[0028] In practical use, the integral molding of the blade holder 1 and the grinding head 2 ensures rigidity and stability during high-speed rotation. The grinding head 2 includes a front grinding section 21 and a chip removal section 22. By electroplating a diamond layer 3 onto the front grinding section 21, the sharpness of the front grinding section 21 can be improved, enabling it to quickly process delicate areas such as the nail cuticle under the drive of the nail polishing machine. The chip removal section 22 works with the front grinding section 21 to quickly remove the chips generated during the polishing process, thereby solving the problem of poor chip removal in existing nail polishing heads. The chip removal section 22 is also electroplated with a diamond layer 3, enabling it to play an auxiliary polishing role. The reinforced transition section 11 can effectively disperse the stress generated during polishing, enhance the structural strength and stability of the connection between the grinding head 2 and the blade holder 1, reduce the risk of breakage at the connection, and extend the service life of the nail polishing head.

[0029] Reference Figure 1 , Figure 2 as well as Figure 3 The outer surface of the front grinding section 21 is provided with a plurality of left helical grooves 2111 and right helical grooves 2112 by turning or grinding. The left helical grooves 2111 and right helical grooves 2112 intersect each other to form a cross groove 211, and a grinding tooth 212 is formed at any intersection of the left helical groove 2111 and the right helical groove 2112. The diamond layer 3 on the front grinding section 21 is attached to the inner wall of the cross groove 211 and the outer surface of the grinding tooth 212. The outer surface of the chip removal section 22 is provided with a continuous helical groove 221 by turning or grinding, and a shielding adhesive layer 2211 is coated in the continuous helical groove 221 to form an embedded fit with it. The protrusion between the continuous helical grooves 221 is set as an auxiliary grinding section 2212, and the diamond layer 3 on the chip removal section 22 is attached to the outer surface of the auxiliary grinding section 2212. Reference Figure 1 , Figure 2 as well as Figure 3The cross groove 211 is connected to one end of the continuous spiral groove 221. In this embodiment, the continuous spiral groove 221 is first formed on the chip removal part 22 of the grinding head 2 by turning or grinding. Then, several left spiral grooves 2111 and right spiral grooves 2112 are formed on the front grinding part 21 of the grinding head 2 by turning or grinding, so that they intersect to form a cross groove 211 connected to the continuous spiral groove 221. The depth of the continuous spiral groove 221 is greater than the depth of the cross groove 211. After the segmented groove is processed, a high-temperature resistant shielding adhesive layer 2211 is first coated on the inner wall of the continuous spiral groove 221. Then, the grinding head 2 is electroplated so that a diamond layer 3 is attached to the outer surface of the front grinding part 21 and the auxiliary grinding part 2212. After the electroplating is completed, the shielding adhesive layer 2211 in the continuous spiral groove 221 is removed to complete the processing.

[0030] In practical use, the left spiral groove 2111 and the right spiral groove 2112 on the front grinding part 21 intersect to form a cross groove 211. When grinding nails with the front grinding part 21, the grinding stress can be dispersed, making the grinding more stable. At the same time, several grinding teeth 212 are formed at the intersection of the cross grooves 211, increasing the number of cutting edges. Combined with the diamond layer 3 attached to the inner wall of the cross groove 211 and the outer surface of the grinding teeth 212, the sharpness of the grinding teeth 212 can be significantly improved, thereby improving the grinding effect. The continuous spiral groove 221 on the chip removal part 22 is coated with a shielding adhesive layer 2211 to prevent the inside of the tank from being covered by diamond particles during electroplating. This ensures that the inner wall of the continuous spiral groove 221 is smooth, making it easy to discharge the chips generated during the grinding process in a spiral direction, thereby solving the problem of poor chip removal in existing nail polishing heads. The protrusions between the continuous spiral grooves 221 are configured as auxiliary grinding parts 2212, and their outer surfaces are also coated with diamond layer 3, so that the auxiliary grinding parts 2212 have a certain sharpness, thereby assisting the front grinding parts 21 in grinding the hard skin on both sides of the nail, thus improving the overall grinding effect; while the cross grooves 211 are connected to the continuous spiral grooves 221 to form a through air circulation channel, which improves the heat dissipation efficiency of the grinding head 2, avoids the grinding head 2 from getting too hot during continuous use, and extends the service life of the grinding head 2. At the same time, the interconnected design facilitates the discharge of chips from the cross grooves 211 to the continuous spiral grooves 221, further improving the chip removal efficiency.

[0031] Reference Figure 1The blade holder 1 is provided with a specification marking ring 4 for distinguishing different specifications of grinding heads 2. In this embodiment, the specification marking ring 4 is integrally formed and fixed on the blade holder 1, and the specification marking ring 4 of different colors represents different specifications of grinding heads 2. In actual use, the design of the specification marking ring 4 makes it easier for users to quickly distinguish different specifications of grinding heads 2, making it more convenient and efficient for users to select and replace nail polishing heads, reducing usage errors caused by specification confusion. At the same time, the integral forming process can maintain the smoothness of the surface of the blade holder 1, avoiding additional friction or scratches during use.

[0032] Reference Figure 1 The blade 1 is provided with a protective component 5 to prevent skin flakes from entering the nail polishing machine. The protective component 5 is fixed to the blade 1 near the nail polishing machine with the blade 1 as the axis. The protective component 5 is umbrella-shaped and has an opening facing the nail polishing machine. In this embodiment, the protective component 5 is made of silicone. The protective component 5 has a socket hole that matches the outer diameter of the blade 1, and the protective component 5 is fitted and fixed to the blade 1 by interference fit.

[0033] In practical use, the protective component 5 can prevent skin flakes from entering the nail polishing machine, thus avoiding the skin flakes affecting the normal operation and service life of the machine. The umbrella-shaped design of the protective component 5 can more comprehensively block the skin flakes from moving towards the nail polishing machine, and does not interfere with the normal rotation and use of the polishing head 2. At the same time, the opening of the protective component 5 faces the nail polishing machine, which can further enhance the guiding and interception effect of the skin flakes, making it impossible for the skin flakes to bypass the protective component 5 and enter the machine. The protective component 5 is made of silicone material with strong tear resistance, which is not easily damaged during use, and only requires simple wiping to remove surface residues during cleaning.

[0034] The implementation principle of this application embodiment is as follows: the tool holder 1 and the grinding head 2 are integrally formed and a reinforced transition part 11 is added to improve the rigidity, stability and stress dispersion ability of the grinding head 2 when rotating at high speed, and reduce the risk of breakage; the grinding head 2 is divided into a front grinding part 21 and a chip removal part 22. The front grinding part 21 is formed by turning or grinding to form a number of left helical grooves 2111 and right helical grooves 2112, and the left helical grooves 2111 and right helical grooves 2112 intersect to form cross grooves 211. When grinding nails in the front grinding part 21, the cross grooves 211 can disperse the grinding stress and make the grinding more stable. A number of grinding teeth 212 are formed at the intersection of the cross grooves 211 to increase the number of cutting edges. At the same time, the diamond layer 3 is attached to the inner wall of the cross grooves 211 and the surface of the grinding teeth 212 by electroplating, which can enhance the sharpness of the grinding teeth 212, thereby improving the grinding effect; The chip removal section 22 is formed into a continuous spiral groove 221 by turning or grinding, and the inner wall of the continuous spiral groove 221 is coated with a shielding adhesive layer 2211. During electroplating, a diamond layer 3 will be attached to the outer surface of the auxiliary grinding section 2212, so that the auxiliary grinding section 2212 has a certain sharpness, thereby assisting the front grinding section 21 in grinding the hard skin on both sides of the nail. After the shielding adhesive is removed, the inner wall of the continuous spiral groove 221 remains smooth, which makes it easy to discharge the chips generated during the grinding process in a spiral direction. The cross groove 211 is connected to the continuous spiral groove 221 to form a through air circulation channel, which improves the heat dissipation efficiency and service life of the grinding head 2. At the same time, the through design facilitates the discharge of chips, further improving the chip removal efficiency. The specification marking ring 4 on the blade 1 makes it easy to quickly distinguish specifications, making it more convenient and efficient for users to select and replace nail polishing heads. The umbrella-shaped protective part 5 can effectively prevent skin flakes from entering the polisher, avoiding skin flakes from affecting the normal operation and service life of the machine. At the same time, the protective part 5 is made of silicone material with strong tear resistance, which is not easily damaged during use and can be easily cleaned by simply wiping away surface residues. The overall structure optimization solves the problem of poor chip removal in existing nail polishing heads, while improving polishing effect, heat dissipation efficiency and service life.
