[First embodiment]
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an exploded perspective view showing the nail polisher of the first embodiment of the present invention, FIG. 2 is a partially broken side view showing the assembled state of the nail polisher of the first embodiment, and FIG. FIG. 4 is an enlarged side view partially broken.

  The nail polisher 1 includes a main body 2 having a motor 21 as a rotational drive mechanism, a polishing unit 31, a file member 3 that is connected to the motor 21 and rotates in conjunction with the motor 21, and the main body 2 and the file. A fan 4 provided between the member 3 and interlocking with the motor 21; a cover member 5 having slits 51 to 54 as through holes; and covering the polishing portion 31 of the file member 3; the main body 2 and the file member 3; And a filter 6 for collecting nail powder.

  The main body 2 is formed in a rectangular parallelepiped shape that can be gripped by a user's hand, for example, and a motor 21 is built in the main body 2. The motor 21 is electric and is driven by a battery (not shown) built in the main body 2 as a power source. The battery is connected to a plug (not shown) built in the main body 2 and can be charged by connecting the plug to a household outlet. The motor 21 includes a rotating shaft 21 a that protrudes from the main body 2.

  In the main body 2, three air intake holes 2 a for allowing air to flow into the main body 2 are formed in the surface around the rotation shaft 21 a in the present embodiment. Further, the side surface of the main body 2 is provided with an air escape hole 2 b for allowing air to flow out of the main body 2. The air flowing in from the air intake hole 2a flows out from the air escape hole 2b. Around the air intake hole 2a, a flange portion 2c for engaging with the cover member 5 is provided protruding upward. The outer surface of the flange portion 2c is threaded. By providing the air escape hole 2b, the air sent from the fan 4 is discharged from the air escape hole 2b, the air is smoothly blown, and the nail shaving powder generated during polishing can be processed.

  The file member 3 has a polishing portion 31 on the upper surface. The polishing portion 31 is circular in a plan view and has a convex curved surface shape with an appropriate curvature radius in a side view. The polishing unit 31 is formed into a file by depositing diamond or the like. On the lower surface of the file member 3, a connecting portion 32 connected to the rotating shaft 21a is provided. When the connecting portion 32 is connected to the rotating shaft 21 a, the file member 3 rotates around the rotating shaft 21 a as the motor 21 rotates. The extension line of the rotation shaft 21a passes through the center of the polishing portion 31 in plan view, and the file member 3 is rotationally symmetric with respect to the extension line of the rotation shaft 21a. The polishing portion may be planar, but in particular when the shape is a convex curved surface, the nail is always in contact with the polishing portion at one point, so that the nail shape can be easily finely adjusted.

  The fan 4 includes four wing portions 41 in the present embodiment. The wing 41 has an angle that causes air to flow downward in FIG. 2 when it rotates as the motor 21 rotates. A connecting hole 42 is formed in a portion surrounded by the wing portions 41. The connecting hole 42 is fitted to the outer surface of the connecting portion 32 of the file member 3, whereby the fan 4 is concentrically connected to the lower portion of the file member 3 and rotates together with the file member 3. The extension line of the rotation shaft 21a passes through the center of the connection hole 42 in plan view, and the file member 3 is rotationally symmetric with respect to the extension line of the rotation shaft 21a.

  The cover member 5 is a member that covers the polishing portion 31, and includes a convex curved upper surface portion 5a that corresponds to the shape of the polishing portion 31, and a cylindrical tube portion 5b that is continuously provided below the upper surface portion 5a. The lower end of the cylindrical portion 5b has an engaging portion 5c that protrudes downward and engages with the main body 2. The upper surface portion 5 a covers the polishing unit 31 with a gap necessary for the polishing unit 31 to rotate with the polishing unit 31.

  Arc-shaped claw slits 51 to 53 are provided on the upper surface portion 5a. These are arcuate shapes that match the shape of the end face of the nail. Since the shape of the end face of the nail varies depending on the individual, it is preferable that the radius of curvature of each arc is different. The width | variety of the nail | claw slit 51-53 is a grade a little larger than the thickness of a general nail | claw. The claw slits 51 to 53 are located on the polishing unit 31 in a state where the cover member 5 is installed. An air intake slit 54 is provided at the peripheral edge of the upper surface portion 5a. These are arc-shaped along the outer periphery of the upper surface part 5a, and are for taking in outside air. The engaging portion 5c is threaded on the outer surface.

  The filter 6 includes a frame portion 61 and a filter portion 62 sandwiched between the frame portions 61. The frame portion has a shape that does not cover the air intake hole 2a, and the filter portion 62 is provided at a position corresponding to at least the air intake hole 2a. A through hole 61a is provided at the center of the frame 61 in plan view, and the rotating shaft 21a is inserted into the through hole 61a. Since this filter 6 is not connected to the rotating shaft 21a, it does not rotate with the rotating shaft 21a.

  As shown in FIG. 1, the filter member 62 is fitted in the flange portion 2 c of the main body 2 so that the filter portion 62 corresponds to the air intake hole 2 a, and the file member is connected to the lower surface of the file member 3 with the fan 4. 3 and 3 are engaged with the rotating shaft 21a, the cover member 5 is put on the rotating shaft 21a, and the threaded portion of the engaging portion 5c is screwed into the threaded portion of the flange portion 2c, as shown in FIGS. Such a nail polisher 1 is completed.

  Next, the usage method of such a nail polisher 1 is demonstrated. When the switch (not shown) of the nail polisher 1 is turned on, the file member 3 rotates. When the nail is inserted vertically into the nail slits 51 to 53 of the cover member 5 in this state, the nail contacts the polishing portion 31 of the file member 3 and is polished and scraped by the rotation of the polishing portion 31. At this time, nail shavings are generated.

  Here, the fan 4 rotates with the file member 3 and pushes the air in the cover member 5 downward. Along with this, the air in the cover member 5 flows as shown by an arrow A in FIGS. Therefore, the nail shavings are pushed downward and collected by the filter 6. The air that has passed through the filter 6 enters the main body 2 through the air intake hole 2a and flows out from the air escape hole 2b. In this way, the nail shavings are collected in the filter portion 62 of the filter 6. The nail shavings accumulated in the filter portion 62 can be easily discarded by replacing the filter 6 or removing the nail shavings by removing the filter 6.

[Second Embodiment]
Then, the nail polisher of 2nd embodiment is demonstrated. The nail polisher 10 of 2nd embodiment has the outer cap 101, the inner cap 102, and the main body 103 as shown in FIGS.

  The main body 103 includes a power source (not shown) and a motor (not shown), and the motor rotates when the switch 131 is turned on. A file member 133 is attached to the shaft 132 of the motor, and the file member 133 rotates as the motor rotates. A fan 134 is provided at the shaft portion of the file member 133, and the fan 134 rotates together with the file member 133. When the file member 133 rotates, the fan 134 generates a downward air flow, that is, an air flow directed from the file member 133 toward the fan 134.

  The inner cap 102 is a cover member that covers the file member 133 and the fan 134 by being fitted to the main body 103, and prevents the finger or the like from being damaged by the rotation of the file member 133 and the fan 134. As shown in FIG. 7B, the inner cap 102 has a small claw hole 121 and a large claw hole 122 formed in a portion corresponding to the file portion of the file member 133. The nail can be shaved by the file member 133 by inserting. The nail hole may be selected depending on the size of the finger or nail. Further, since the inner cap 102 exists around the claw hole, a finger or the like does not touch the file member 133.

  The outer cap 101 is a cover member that covers the outer side of the inner cap 102 by being fitted to the inner cap 102, and prevents a finger or the like from touching the file member 133. As shown in FIG. 7A, the outer cap 101 has a finger hole 131 formed in a portion corresponding to the small claw hole 121 or the large claw hole 122 of the inner cap 102. The nail can be shaved by the file member 133 by inserting. Further, by selecting the direction of the outer cap 101 relative to the inner cap 102, the finger hole 131 can be positioned on either the small claw hole 121 or the large claw hole 122. When the finger hole 131 is positioned on one of the nail holes, the other nail hole is covered, so that safety can be further ensured. The outer cap 101 is made of a transparent material, and it is possible to visually recognize which of the small claw hole 121 and the large claw hole 122 of the inner cap 102 corresponds to the finger hole 131.

  Each of the inner cap 102 and the outer cap 3 is a dome-shaped member that covers the file member 133 and the fan 134. Since the outer cap 101 is slightly larger than the inner cap 102, as shown in FIG. In a state where the outer cap 101 is covered, a cylindrical gap S exists between the inner cap 102 and the outer cap 101. A portion of the inner cap 102 below the gap S and above the fan 134 is provided with a slit 123 as a suction hole for sucking nail powder into the main body. An air hole is provided at a position below the inner cap 102 and below the fan 134, and a filter 124 is installed in the air hole. The filter 124 is fine enough to allow air to pass but not to allow nail shavings to pass through.

  An operation when the nail is shaved using the nail polisher of the second embodiment as described above will be described. As shown in FIGS. 5 and 8, the finger hole 131 is positioned on either the small claw hole 121 or the large claw hole 122 while the main body 103 is covered with the inner cap 102 and the outer cap 101. Subsequently, the file member 133 and the fan 134 are rotated by turning on the switch 31. A fingertip is inserted into the finger hole 131, and a nail is inserted into the small claw hole 121 or the large claw hole 122, and the end of the nail is shaved with the file member 133. At this time, the finger contacts the inner cap 102 and does not touch the file member 133.

  Shaving is generated by scraping the nail. A part of the shavings enters the gap between the inner cap 102 and the file member 133 as shown as a in FIG. 8, but most of the shavings are formed between the inner cap 102 and the outer cap 101 as shown in FIG. The gap S passes through the slit 123 and enters the inner cap 102. At this time, since the fan 134 is rotated and a downward airflow is generated in FIG. 8, the shavings are sucked into the inner cap 102 through the route a or b and spilled out of the outer cap 101. There is almost no end. The air flow generated by the fan 134 is discharged out of the inner cap 102 through an air hole drilled below the fan 134, as indicated by c in FIG. Along with this, the shavings in the inner cap 102 also move, but cannot pass through the filter 124 and are collected by the filter 124.

  According to the nail polisher 10 of 2nd embodiment as mentioned above, a nail | claw can be shaved safely and the shavings in that case can be collected inside the nail polisher 10. FIG. Further, since the outer cap 101, the inner cap 102, the file member 133, and the fan 134 can be disassembled as shown in FIG. 6, the nail shavings can be poured and kept clean by removing them and washing them with water.

[Third embodiment]
Then, the nail polisher of 3rd embodiment is demonstrated. As shown in FIGS. 9 to 11, the nail polisher 20 of the third embodiment includes a cap 201 and a main body 202.

  The main body 202 incorporates a power source 221 and a motor 222, and the motor 222 rotates by turning on a forward / reverse switch (not shown). The rotating shaft of the motor 222 is provided with a fan 223 at the upper part and a gear 224 at the lower part, and these rotate as the motor 222 rotates. The gear 224 meshes with a gear 225 having a larger diameter. The large-diameter gear 225 is connected to the file member 227 via the shaft 226. Therefore, the rotational speed of the file member 227 is lower than the rotational speed of the fan 223, and the torque of the file member 227 is higher than the torque of the fan 223.

  Unlike the fans of the first embodiment and the second embodiment, the fan 223 has a wing member parallel to the rotation axis. Therefore, even if it is rotated in any direction, it acts to push air in the centrifugal direction. In addition, a filter 229 is provided on the upper side of the fan to collect nail shavings from above. An air hole 230 is formed on the side of the fan, and the air pushed out by the fan is discharged from the air hole 230. The file member 227 has a filed portion formed by diamond deposition on the upper surface and side surfaces. At both sides of the file member 227, mounting portions 231 for mounting the cap 201 to the main body 202 are provided upright.

  As shown in FIG. 11, the cap 201 has a first slit 211 and a second slit 212 provided on the upper surface, and a third slit 213 on the side surface. It has a notch 214. Further, a screw hole 215 for being screwed to the mounting portion 231 is formed.

  The first slit 211 is provided at a position close to the rotational axis of the file member 227. As the file member 227 is closer to the rotation axis, the surface speed is lower and the torque is higher. Therefore, the use of this slit to cut the nail is suitable for the case where it is required to cut off little by little, such as when finishing. It is also suitable for cutting hard nails such as nails. On the other hand, the second slit 212 is provided in a portion near the circumference of the file member 227. Since the surface speed of the file member is high at this portion, the nail can be quickly cut when the nail is cut using this slit. Moreover, since the 3rd slit 213 is provided facing the side surface of the file member 227, the surface speed of the file member is the fastest. In addition, the shape of the nail can be adjusted using the curve on the side surface of the file member 227. Furthermore, since the corner portion of the file member 227 is exposed from the notch 214, it is possible to adjust a difficult-to-shave portion such as a toenail using this corner portion. Further, the nail polisher 20 employs a forward / reverse switch and can change the rotation direction of the file member 227. Therefore, when the right side of the nail is shaved and when the left side is shaved, adjustments such as changing the rotation direction can be performed, and a situation where the nails are shaved in the opposite direction can be avoided.

  When the nail is shaved using the nail polisher 20, the nail shaving powder enters the cap 201 from the slit. Since the fan 223 pushes air in the centrifugal direction by rotation, air is pushed out from the air hole 230, and air flows from the cap 201 side to the fan 223 side through the filter 229. Therefore, the nail shavings are collected by the filter 229. When the forward / reverse switch is switched, the fan 223 rotates in the reverse direction. However, since the blade member of the fan 223 is parallel to the rotation axis, the air is moved in the centrifugal direction regardless of which direction the fan is rotated. It acts as an extrusion and air does not flow backward. When nail shavings accumulate, the cap 201 may be removed and the filter 229 replaced, and the cap 201 can be washed with water. If an O-ring is attached to the base of the file member 227, water can be prevented from entering the main body, and the main body can also be washed with water.

[Modification]
Then, the modification of the file member is demonstrated. The file members 301, 302, 303, and 304 shown in FIG. 12 are all modifications of the file member. Each of these file members has a plurality of holes extending from the front surface to the back surface and having an angle slightly inclined with respect to the vertical direction. More specifically, the file member 301 of the first modification shown in FIGS. 12A and 12B has a through-hole having an inclination such that the upper side is slightly closer to the center of the rotation axis with respect to the vertical. Eight points are drilled in a point-symmetrical manner around the rotation axis. The file member 302 of the second modification shown in FIGS. 12 (C) and (D) has four through-holes having an inclination so that the upper side is slightly closer to the center of the rotation axis than the vertical, and the rotation axis is It is drilled point-symmetrically as the center. The file member 303 of the third modification shown in FIGS. 12 (E) and 12 (F) has eight through-holes that are slightly inclined in a direction parallel to the circumference with respect to the vertical, with the rotation axis as the center. It is drilled symmetrically. The file member 304 of the fourth modification shown in FIGS. 12 (G) and 12 (H) has four through holes slightly inclined in a direction parallel to the circumference with respect to the vertical, and the point is centered on the rotation axis. It is drilled symmetrically. By providing a through hole in the file member in this manner, the nail shaving powder falls downward through the through hole. Below the file member, suction by the fan is performed as described above, so that the shavings can be effectively collected. Moreover, when the through hole is inclined with respect to the vertical, an air flow is generated during rotation, and the shavings can be sent downward. In particular, when the through hole is inclined in the direction parallel to the circumference and in the direction of rotation of the file member, the through hole functions as a fan, and thus a downward airflow is generated particularly strongly during rotation.

  As described above, the nail polisher of the present invention includes a main body having a rotation drive mechanism, a polishing unit, a file member connected to the rotation drive mechanism and interlocking with the rotation drive mechanism, and a main body and a file member. And a cover member that has at least one through hole and covers the polishing portion of the file member, and has various types within a range not departing from the gist thereof. It can be implemented in the form. For example, an appropriate material can be used for the nail polisher, and the polishing portion may not be formed by diamond vapor deposition. The dimensions can be appropriately set based on the thickness of a general nail. Even when there is no air intake slit of the cover member, the same effect can be achieved by the inflow of air from the claw slit. The nail polisher can be used as a nail polisher for pets by changing the size of the nail slit in addition to nail polish for healthy and disabled people.
