Description

Multifunctional nail polish grinding head and production method thereof Technical Field

[0001] The present application relates to the field of nail art tools, and in particular to a multifunctional nail art grinding head and a production method thereof. Background Art

[0002] As people's quality of life continues to improve, the beauty industry is also developing rapidly, and the requirements for beauty products are getting higher and higher, including nail art. With the increase in nail art shapes and styles, the corresponding need for better shaping effects and convenience has made it difficult for existing nail polish grinding heads to meet market requirements.

[0003] At present, the nail grinding head consists of a fixedly connected cutter head and a handle. The handle is detachable and fixedly installed in the nail polisher. The nail polisher drives the cutter head to rotate through the handle, and the cutter head grinds and removes the accessories on the nails (hard glue, soft glue, and base glue, etc.). There are multiple grinding teeth arranged at intervals on the cutter head, and the grinding teeth are tilted along the rotation direction of the cutter head. Cutters with different tooth pitches are used for different grinding situations. When the outer diameter of the grinding head is the same, a smaller tooth pitch means more teeth, and the sharpness is small during use, which is suitable for fine processing and small amounts of grinding; a larger tooth pitch means fewer teeth, and the sharpness is high during use, which is suitable for rough processing and large amounts of grinding.

[0004] When users remove the accessories on the nails, they often need to use a grinding head with a larger tooth pitch for rough grinding first, then replace the nail grinding head, and use a grinding head with a smaller tooth pitch for fine grinding before removing the hard glue, soft glue and base glue. In this way, users need to constantly replace the nail grinding head, which is inconvenient to remove the nails.

[0005] Summary of the Invention

[0006] In order to facilitate users to remove nail accessories of different hardness, the present application provides a multifunctional nail grinding head and a production method thereof.

[0007] In the first aspect, the present application provides a multifunctional nail grinding head adopting the following technical solutions:

[0008] A multifunctional nail grinding head includes a cutter head and a handle. A plurality of first spiral grooves are spaced apart on the circumferential side wall of the cutter head. A rack is formed on the cutter head between each two adjacent first spiral grooves. A plurality of groups of large tooth segments are formed in the radial cross-section of the cutter head along the circumferential direction of the cutter head. Each group of the large tooth segments is composed of a plurality of racks. The arrangement density of the racks in a group of the large tooth segments is from sparse to dense or from dense to sparse or staggered with sparse and dense along the circumference of the cutter head.

[0009] By adopting the above technical solution, when using the nail grinding head for processing and grinding, the nail tool drives the cutter head to rotate through the cutter handle, and the cutter head drives multiple groups of large tooth segments to rotate. The rack arrangement density in each group of large tooth segments is different, so that the cutter head can perform rough grinding and fine grinding at the same time, and there is no need to constantly replace the nail grinding head, which makes it convenient for users to remove nail accessories of different hardness.

[0010] Preferably, a plurality of second spiral grooves are spaced apart on the circumferential side wall of the cutter head, and the rotation direction of the second spiral grooves is opposite to that of the first spiral grooves. The plurality of second spiral grooves divide a rack into a plurality of teeth, and each of the teeth is symmetrically arranged with the line connecting its own blade to the axis of the cutter head as the symmetry line.

[0011] By adopting the above technical solution, the second spiral groove divides a rack into multiple teeth, reducing the blade length of the rack, making the debris generated by grinding smaller, and the second spiral groove facilitates the discharge of debris; at the same time, the teeth are symmetrically arranged along the symmetry line, so that the cutter head can grind back and forth.

[0012] Preferably, a group of the large tooth segments includes multiple groups of small tooth segments arranged in sequence, any of the small tooth segments is composed of several racks, the spacing between two adjacent racks in each group of the small tooth segments is the same, and the rack arrangement density of different small tooth segments is different.

[0013] By adopting the above technical solution, while each group of large tooth segments rotates and grinds, multiple groups of small tooth segments with different arrangement densities are ground in sequence. The number of racks in any group of small tooth segments determines the length of the small tooth segment. When the small tooth segments with a sparse rack arrangement are longer, the degree of rough grinding can be increased; when the small tooth segments with a dense rack arrangement are longer, the degree of fine grinding can be increased. This allows the degree of rough grinding or fine grinding in each group of large tooth segments to be adjusted, thereby improving the applicability of the nail grinding head.

[0014] Preferably, the number of racks corresponding to the small tooth segments in different large tooth segments is the same, and the arrangement rules of different large tooth segments are the same.

[0015] By adopting the above technical solution, the arrangement density and the number of racks in the small tooth segments in each group of large tooth segments are the same, so that the grinding effects of multiple groups of large tooth segments are the same, thereby improving the grinding efficiency of the nail grinding head.

[0016] Preferably, a support portion is formed on the side wall of the cutting tooth close to the first spiral groove in a protruding manner, and the support portion is arranged along the rotation direction of the first spiral groove.

[0017] By adopting the above technical solution, the support portion increases the structural strength of the blade teeth, so that the blade teeth have high sharpness and are not easily damaged.

[0018] Preferably, the tooth height of the rack increases with increasing rack sparseness, and the tooth height of the rack decreases with increasing rack density.

[0019] By adopting the above technical solution, the larger the distance between the teeth, the greater the tooth height of the teeth, and the wider the tooth roots of the teeth, thereby making the tooth structure stronger.

[0020] Preferably, the cross-section of the first spiral groove is in the shape of an inverted trapezoid.

[0021] By adopting the above technical solution, the inverted trapezoidal first spiral groove increases the tooth groove width between adjacent teeth, making it difficult for grinding debris to get stuck in the first spiral groove. At the same time, after the nail grinding head is used, it is easy to clean the debris in the first spiral groove.

[0022] Preferably, the distance between two adjacent racks is proportional to the depth of the first spiral groove.

[0023] By adopting the above technical solution, the larger the distance between two adjacent racks, the deeper the depth of the first spiral groove between the two adjacent racks, which makes the tooth height of the cutter teeth higher, increases the structural strength of the cutter teeth, and makes the cutter teeth less likely to be damaged during rough machining and grinding.

[0024] Preferably, the helical angle between the first spiral groove and the second spiral groove is 30-120°.

[0025] In a second aspect, the present application provides a method for producing a multifunctional nail grinding head using the following technical solution:

[0026] A method for producing a multifunctional nail grinding head adopts the above-mentioned multifunctional nail grinding head, including the following processing steps: S1: processing the handle and the cutter head into a step shape; S2: opening a plurality of first spiral grooves on the cutter head and forming a plurality of racks on the cutter head.

[0027] By adopting the above technical solution, a plurality of first spiral grooves are firstly formed on the cutter head using a machine tool, so that a nail grinding head can be manufactured, thereby making the production efficiency of the nail grinding head higher.

[0028] Preferably, in step S2, S2.1: multiple No. 1 spiral grooves are opened at equal intervals along the circumference of the cutter head to form multiple racks, and the multiple racks are divided into multiple groups of large tooth segments; S2.2: in a group of large tooth segments, multiple racks form multiple groups of small tooth segments, and the first small tooth segment is composed of several racks; S2.3: in the second small tooth segment, a No. 2 spiral groove is opened for each rack covered, and the depth of the No. 2 spiral groove is greater than the No. 1 spiral groove; S2.4: in the third small tooth segment, a No. 3 spiral groove is opened for each two racks covered, and the depth of the No. 3 spiral groove is greater than the No. 2 spiral groove; S2.5: with reference to steps S2.3 and S2.4, a No. 4 spiral groove, a No. 5 spiral groove, etc. with a larger tooth groove depth are opened until a group of large tooth segments is completed and multiple groups of small tooth segments are arranged sequentially or randomly along the circumference of the cutter head; S2.6: steps S2.3-S2.5 are repeated to process the remaining large tooth segments.

[0029] By adopting the above technical solution, a No. 1 spiral groove is first opened to form multiple racks of the same size, and then a No. 2 spiral groove, a No. 3 spiral groove, etc. are opened based on the multiple racks, so that racks with different arrangement densities and tooth heights can be processed on the cutter head more accurately and quickly.

[0030] Preferably, in steps S2.3-S2.5, after the second spiral groove, the third spiral groove, and the fourth spiral groove are opened, support portions are formed on the side walls of the cutting teeth on both sides of the spiral groove.

[0031] By adopting the above technical solution, after the second spiral groove, the third spiral groove and the fourth spiral groove are opened, support parts can be formed on the side walls of the teeth on both sides of the spiral groove, thereby facilitating the processing of the cutter head.

[0032] Preferably, the method further includes step S3: providing a plurality of second spiral grooves on the cutter head, the second spiral grooves being staggered with the first spiral grooves.

[0033] By adopting the above technical solution, the second spiral groove divides a rack into multiple teeth, reducing the blade length of the rack, making the debris generated by grinding smaller, and the second spiral groove facilitates the discharge of debris.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. By using the cutter head to drive the teeth with different arrangement densities to rotate, the cutter head can perform rough grinding and fine grinding at the same time, without the need to constantly replace the nail grinding head, making it easier for users to remove nail ornaments of different hardness;

[0036] 2. By combining multiple groups of small tooth segments into a large tooth segment, when each group of large tooth segments rotates and grinds, multiple groups of small tooth segments with different arrangement densities are ground in sequence. The number of racks in any group of small tooth segments determines the length of the small tooth segment. Small tooth segments of different lengths make it possible to adjust the degree of roughing or finishing grinding in each group of large tooth segments, thereby improving the applicability of the nail grinding head;

[0037] 3. The inverted trapezoidal first spiral groove increases the tooth groove width between adjacent teeth, making it difficult for grinding debris to get stuck in the first spiral groove. At the same time, after the nail grinding head is used, it is easy to clean the debris in the first spiral groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present application is further described in detail below with reference to Figures 1-8.

[0048] Example 1:

[0049] The embodiment of the present application discloses a multifunctional nail grinding head.

[0050] 1 , a multifunctional nail grinding head includes a cutter head 1 and a handle 2 . The cutter head 1 is cylindrical, and the handle 2 is rod-shaped. The handle 2 is coaxially plugged into the end of the cutter head 1 and welded to the cutter head 1 .

[0051] 1 and 2 , a first spiral groove 3 is provided on the outer wall of the cutter head 1 along its own axial direction. The first spiral groove 3 is a right-handed groove. There are multiple first spiral grooves 3 , which are spaced apart along the circumferential direction of the cutter head 1 , and a left-handed rack 4 is formed between two adjacent first spiral grooves 3 .

[0052] Referring to Figure 2 , in a cross-section along the diameter of the cutter head 1, multiple groups of large tooth segments 5 are arranged in sequence along the circumference of the outer wall of the cutter head 1. Each group of large tooth segments 5 is composed of multiple groups of small tooth segments 51 arranged in sequence, and each group of small tooth segments 51 is composed of several racks 4. In this embodiment, there are six groups of large tooth segments 5 around the outer wall of the cutter head 1. Each group of large tooth segments 5 is composed of four groups of small tooth segments 51, and each group of small tooth segments 51 is composed of two racks 4.

[0053] In the counterclockwise direction (see Figure 2), the spacing between the two racks 4 in the four groups of small tooth segments 51 gradually decreases, causing the arrangement density of the racks 4 in one large tooth segment 5 to change from sparse to dense. When using the nail grinding head for processing and grinding, the nail tool drives the cutter head 1 to rotate via the handle 2, and the cutter head 1 drives the six groups of large tooth segments 5 to rotate synchronously. The density of the racks 4 in each group of large tooth segments 5 is different, allowing the cutter head 1 to perform both rough grinding and fine grinding simultaneously, eliminating the need to constantly replace the nail grinding head, making it easier for manicurists to remove nail accessories of different hardness.

[0054] In a radial cross-section of the cutter head 1, the line of symmetry is defined by the connection between the cutting edge of the rack 4 and the center of the cutter head 1. The cutting edges of each rack 4 are mirrored along this line of symmetry. Compared to conventional cutter heads 1 that can only move in a single direction for grinding, the symmetrical arrangement of the racks 4 allows the cutter head 1 to move back and forth on the nail during the grinding process, making it easier for the manicurist to quickly remove nail art accessories.

[0055] The depth of the first spiral groove 3 is proportional to the distance between the racks 4. When the racks 4 are arranged more densely in the large tooth segment 5, the spacing between two adjacent racks 4 is smaller, and at the same time, the depth of the first spiral groove 3 between two adjacent racks 4 is shallower; when the racks 4 are arranged more sparsely in the large tooth segment 5, the distance between two adjacent racks 4 is larger, and at the same time, the depth of the first spiral groove 3 between two adjacent racks 4 is deeper.

[0056] The more sparsely arranged the racks 4 are, the deeper the first spiral grooves 3 are, which in turn results in a higher tooth height of the rack 4 and a wider tooth root of the rack 4, thereby improving the structural strength of the rack 4. When the more sparsely arranged racks 4 are rough-ground, the racks 4 with wider tooth roots have a higher structural strength, making the racks 4 less susceptible to damage.

[0057] A support portion 7 is integrally formed along the spiral direction of the first spiral groove 3 in the middle portion of the side wall of the rack 4 near the first spiral groove 3. In a radial cross-section of the cutter head 1, the support portion 7 is located on the tooth surface of the rack 4 and extends away from the rack 4. The width of the support portion 7 on the side near the rack 4 is greater than the width on the side away from the rack 4, and the end of the support portion 7 away from the rack 4 is pointed. The support portion 7 increases the structural strength of the rack 4, further reducing the risk of damage to the rack 4.

[0058] The first spiral groove 3 has an inverted trapezoidal cross-section, and the deeper the first spiral groove 3, the larger the inverted trapezoidal area of ​​the first spiral groove 3. The inverted trapezoidal shape of the first spiral groove 3 increases the tooth groove width between adjacent teeth 41, making it less likely that grinding debris will get stuck in the first spiral groove 3. This facilitates cleaning of the debris in the first spiral groove 3 after use of the nail grinding head. Furthermore, the sparser the arrangement of the racks 4, the larger the grinding debris. In this case, the deeper the first spiral groove 3, the easier it is to remove larger debris.

[0059] 1 , a second spiral groove 6 is formed on the outer wall of the cutter head 1 along its own axis. The second spiral groove 6 is a left-hand groove. The angle between the first spiral groove 3 and the second spiral groove 6 is 30-120°, and the depth of the second spiral groove 6 is greater than the depth of the first spiral groove 3. Multiple second spiral grooves 6 are formed, and the multiple second spiral grooves 6 are evenly spaced along the circumference of the cutter head 1. The multiple second spiral grooves 6 divide each rack 4 into a plurality of teeth 41.

[0060] The second spiral groove 6 divides the rack 4 into multiple teeth 41, reducing the length of the rack 4's blade. As the cutter head 1 rotates, each tooth 41 with a shorter blade grinds the nail art accessory, resulting in smaller grinding debris and making it less likely to get stuck in the first spiral groove 3. Furthermore, during the grinding process, the grinding debris is discharged from the cutter head 1 through the deeper second spiral groove 6, further preventing it from getting stuck in the first spiral groove 3.

[0061] The implementation principle of Example 1 of the present application is as follows: When using a nail grinding head for processing and grinding, the nail tool drives the cutter head 1 to rotate via the cutter handle 2, and the cutter head 1 drives the six groups of large tooth segments 5 to rotate synchronously. The racks 4 in each group of large tooth segments 5 are arranged at different densities, allowing the cutter head 1 to perform both rough grinding and fine grinding simultaneously, thereby eliminating the need to constantly replace the nail grinding head; the racks 4 are symmetrically arranged, allowing the cutter head 1 to move back and forth on the nail during the grinding process; the larger the spacing between the teeth 41, the greater the tooth height of the teeth 41, making the teeth 41 more structurally strong. This facilitates the manicurist to quickly and stably remove nail ornaments of different hardness.

[0062] Example 2:

[0063] 3 , the difference between this embodiment and embodiment 1 is that there are three groups of large tooth segments 5 on the circumference of the outer wall of the cutter head 1, and each group of large tooth segments 5 is composed of four groups of small tooth segments 51. In the counterclockwise direction (refer to FIG2 ), the first group of small tooth segments 51 is composed of two racks 4, the second group of small tooth segments 51 is composed of three racks 4, the third group of small tooth segments 51 is composed of four racks 4, and the fourth group of small tooth segments 51 is composed of five racks 4.

[0064] From the first to the fourth group of small tooth segments 51, the spacing between adjacent racks 4 within each small tooth segment 51 gradually decreases, and within any small tooth segment 51, the spacing between adjacent racks 4 is the same. Within a group of large tooth segments 5, the density of the racks 4 increases from sparse to dense in a counterclockwise direction, and the number of racks 4 increases within each of the four small tooth segments 51.

[0065] The number of racks 4 in any group of small tooth segments 51 determines the length of that group. The different lengths of the small tooth segments 51 allow for adjustment of the degree of roughing or finishing grinding within each group of large tooth segments 5. When using the cutter head 1 for grinding, a smaller number of racks 4 are arranged with a sparser density, while a larger number are arranged with a denser density. This allows the cutter head 1 to achieve both roughing and finishing grinding, thereby enhancing the applicability of the nail grinding head.

[0066] The implementation principle of Example 2 of the present application is: when each group of large tooth segments 5 rotates and grinds, multiple groups of small tooth segments 51 with different arrangement densities are ground in sequence. The number of racks 4 in any group of small tooth segments 51 determines the length of the small tooth segment 51. The small tooth segments 51 of different lengths make it possible to adjust the degree of rough grinding or fine grinding in each group of large tooth segments 5, thereby improving the applicability of the nail grinding head.

[0067] Example 3:

[0068] 4 , the difference between this embodiment and embodiment 1 is that, in the clockwise direction (referring to FIG4 ), the distance between the two racks 4 in the first group of small tooth segments 51 is smaller than the distance between the two racks 4 in the second group of small tooth segments 51, the distance between the two racks 4 in the second group of small tooth segments 51 is smaller than the distance between the two racks 4 in the third group of small tooth segments 51, the distance between the two racks 4 in the third group of small tooth segments 51 is larger than the distance between the two racks 4 in the fourth group of small tooth segments 51, and the distance between the two racks 4 in the fourth group of small tooth segments 51 is larger than the distance between the two racks 4 in the first group of small tooth segments 51 in the next large tooth segment 5.

[0069] The four groups of small tooth segments 51 in the first group of large tooth segments 5 and the first group of small tooth segments 51 in the next group of large tooth segments 5 are arranged symmetrically with the midline of the third group of small tooth segments 51 in the first group of large tooth segments 5 as the axis of symmetry. In a cross-section along the diameter of the cutter head 1, the arrangement density of the teeth 41 along the circumference of the cross-section is: dense, sparse, dense, sparse, or dense, sparse, dense, sparse, alternating.

[0070] The implementation principle of Example 3 of the present application is: along the circumferential direction of the cross section of the cutter head 1, the arrangement density of the teeth 41 is: dense, sparse, dense, sparse or dense and sparse, dense, sparse, dense, alternating arrangement, so that when the cutter head 1 is ground, the alternation between rough grinding and fine grinding is smoother, thereby making the grinding effect of the cutter head 1 better.

[0071] Example 4:

[0072] 5 , the embodiment of the present application differs from embodiment 1 in that the cutter head 1 can also be set to other shapes such as A1 to A11, and the cutter head 1 is always coaxially mounted with the handle 2 . Among them, the cutter head A1 is cylindrical; the cutter head A2 is cylindrical, and the end of the cutter head 1 is provided with a rounded corner; the cutter head A3 is cylindrical, and the end of the cutter head 1 is provided with a chamfer; the cutter head A4 has a cylindrical bottom, a hemispherical top, and a smooth hemispherical surface; the cutter head A5 has a cylindrical bottom, a hemispherical top, and a spiral groove on the hemispherical surface; the cutter head A6 is a frustum; the cutter head A7 is a frustum, and the end of the cutter head 1 is provided with a rounded corner; the cutter head A8 has a frustum, a hemispherical top, and a smooth hemispherical surface; the cutter head A9 has a frustum, a hemispherical top, and a spiral groove on the hemispherical surface; the cutter head A10 is a semi-ellipsoid; the cutter head A11 is a semi-ellipsoid, and the end of the cutter head 1 is flat.

The groove depth of the second spiral groove 32 is 0.35 mm, and the width of the second spiral groove 32 is greater than the width of the first spiral groove 31. The second spiral groove 32 grinds away the third rack 4 in the set of large tooth segments 5. At the same time, support portions 7 are formed on the sidewalls of the two racks 4 on both sides of the second spiral groove 32.
