It is the front view seen from the exhaust port 36 side of ventilation | gas_flowing of the accommodating part with a dust collection part which was mounted and integrated.
The dust collecting unit 29 equipped with a ventilation plate 43 that adsorbs the nail polishing powder attached to the back side of the storage unit 24 is provided with a fan 28 for collecting dust that is rotated by an electric motor 41 on the back side, and the dust collecting unit. A through-hole 31 is provided in the back upper surface plate 30 of 29, side partition walls 35, 35 are formed inside the outer wall 33 of the base plate 32 of the dust collecting portion 29 via a groove ventilation passage 34, and the groove ventilation passage portion is formed.

It is a disguised configuration.

FIG. 4 is an enlarged perspective view of the ventilation plate, and FIG. 5 is an enlarged cross-sectional view of FIG.
The ventilation plate 43 superposes a wire mesh 40 and a filter 42 that adsorbs nail polishing powder between an upper clamping plate 39 and a lower clamping plate 39A having a through hole 38 in the center, and exhausts air to the center and both sides in front of the dust collecting portion 29. An opening 36 is provided, a ventilation plate 43 is inserted between the upper surface of the back upper surface plate 30 and the side partition wall 35, and connected to the dry battery 46 of the battery storage unit 45 behind the dust collecting unit 29. In this configuration, the nail polish powder is sucked together with the air through the wire mesh and the filter 42 and the nail polish powder is adsorbed on the filter 42.

The main body 1 is formed in a substantially cubic shape that can be gripped by a user's hand, and an electric motor is built in the main body 1. Moreover, the main body 1 has a watertight structure and has waterproof performance. For this reason, it can wash with water by removing from the battery accommodating part 14.
Although the electric motor is driven by a dry battery, it can be driven by using a secondary battery (not shown) built in the main body as a power source. The secondary battery is connected to a plug (not shown) built in the main body, and can be charged by connecting the plug to a household outlet. The electric motor includes a rotating shaft protruding from the main body.

  The fan 28 in the dust collecting part 29 takes in air from the through hole of the back surface plate on which the metal mesh and the filter are arranged, and makes the dust collecting part 29 have a negative pressure to let the air flow out from the exhaust port and the groove vent passage. The inside of the dust collecting unit 29 is set to a negative pressure, the air is exhausted to the outside, the air is smoothly blown, and the nail polishing powder scattered around during polishing can be adsorbed to the filter for processing. The filter can also be removed and cleaned.

  The polishing member has a polishing portion on the upper surface, and the polishing portion is circular in a plan view, and has a convex curve shape or an end plane shape with an appropriate curvature radius in a side view. The polishing portion is formed into a file by depositing diamond or the like. A rear side of the polishing member is connected to a rotating shaft via a connecting sleeve. By connecting the connecting sleeve to the rotating shaft, the polishing member rotates around the rotating shaft as the electric motor rotates.

Next, two methods of using the nail polisher will be described.
The first device is used by energizing and connecting the main body 1 and the battery housing portion 14 with the cord 22 and separating the main body 1 and the dry-ground storage portion 14 without connecting them, The main body 1 equipped with the electric motor 3 and the polishing member 8 is gripped and the polishing unit is brought near the nail to be polished for use.
Further, the second device is used when the main body 1 and the battery storage section 14 are connected and energized with the cord 22 and the main body 1 and the dry-ground storage section 14 are used by fitting and coupling. The cube has a magnetic connection portion 13 at the center of the fitting protrusion 12 on one side 11, and a fitting recess that fits with the fitting protrusion 12 on one side 19 of the battery storage portion 14 of the other rectangular parallelepiped. 20 and the magnetic connection portion 21 is formed at the center of the fitting recess 20, so that the magnetic connection portion 13 of the fitting protrusion 12 of the main body 1, the fitting recess 20, the magnetism, and the fitting coupling, The fitting protrusions 12 can be replaced in the four directions of front, rear, left and right of the fitting recess 20 of the battery housing portion 14, and as a result, the axial direction of the polishing member 8 of the main body 1 with respect to the battery housing portion 14 is changed to four directions. The direction is changed and fitted and coupled.

A dust collecting unit 29 for adsorbing nail polishing powder attached to the back side of the storage unit 24 is provided with a fan 28 that is rotated by an electric motor 41 on the back side, and a through hole 31 is provided in the back upper surface plate 30 of the dust collecting unit 29. Side partition walls 35, 35 are formed inside the outer wall 33 of the base plate 32 of the dust collecting portion 29 via a groove ventilation passage 34, and the ventilation plate 43 is fitted between the back upper surface plate 30 and the side partition wall 35. Then, the nail is polished by the rotation of the polishing member 8, the nail is scraped off, and nail polishing powder is generated.
The nail polishing powder is collected by the filter 42. The nail polishing powder accumulated in the filter 42 is scattered around by replacing the filter 42 or removing the filter 41 and removing the nail polishing powder. It can be thrown away easily without letting it go.

A ventilation plate 43 located below the discharge port 36 of the dust collecting unit 29 and above the fan 28 is provided with a through hole 38 for sucking nail polishing powder into the main body.
Further, a through hole 31 is provided in the upper surface plate 30 of the dust collecting portion 29, and a filter is sandwiched between the through hole 31 and a metal mesh is inserted under the through hole 31, and the ventilation plate 43 is inserted and fixed between the upper and lower clamping plates 39 and 39A. An air exhaust port is provided at a position below the fan 28 and below the fan 28, and a filter 42 is installed on the sound vent plate. The filter 42 is fine enough to allow air to pass but not nail polishing powder.

  The main body 1 has a built-in electric motor 3, and the electric motor rotates by turning on a forward / reverse switch (not shown). An abrasive member is attached to the rotating shaft of the electric motor via a connecting sleeve 5.

When the fan 28 mounted on the dust collecting unit 29 is orthogonal to the transmission shaft, it acts to draw air in the centrifugal direction, regardless of the direction of rotation.
Further, nail polishing powder is collected on the upper side of the fan 28 from above the ventilation plate 43 equipped with the filter 42.
A through hole 38 is formed above the fan, and outside air drawn in by the fan is sucked from the through hole 38 and exhausted through the filter 42 from the discharge port 36 of the dust collecting unit 29.
Various kinds of polishing members 8 are prepared, and the upper surface and side surfaces of the polishing surface are polishing portions by diamond vapor deposition.

Further, the shape of the nail can be adjusted using the inclined surface of the side surface of the polishing member.
Adjustments such as changing the direction of rotation can be performed when the right side of the nail is cut and when the left side is cut, and a situation where the nail is scraped to the opposite side of the nail can be avoided.

  Even when the fan 28 is rotated in the reverse direction, the inside of the collection case always has a negative pressure, and the nail polishing powder can be sucked. If nail polishing powder accumulates, the filter 42 may be removed and the filter 42 replaced, and the filter 42 can be washed with water.

  Further, the nail polisher of the present invention uses a main body provided with a rotary polishing drive mechanism, a battery housing part and a cord to be energized and used separately, and the two are integrally connected by magnetism and fitting to store the battery. The axial direction of the polishing member can be changed with respect to the part.
