DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric nail polisher that uses a rotating polisher rotated by a motor to polish nails, such as sharpening the tip of the nail or polishing the surface of the nail. In addition, the dust cover prevents the polishing powder from scattering, and the suction fan collects dust in the dust collection chamber, making it easy to clean the suction fan, the dust collection chamber, and the dust cover. In addition, the rotary abrasive element can be easily replaced.

The present invention will be described in detail below with reference to embodiments shown in FIGS. 1 to 4.

This electric nail polisher has an external appearance as shown in FIG. 1, and is used by removing the cap 2 from the main body 1, which is of a size suitable for being held with one hand.

The main body 1 is constructed by connecting a similarly cylindrical motor case 4 to the upper end of a cylindrical battery case 3, and the lower end opening of the main body 1, and therefore the lower end opening of the battery case 3, is covered with a dish-shaped bottom cover 5. When closed, a cylindrical fan cover 6 is removably connected to the upper end of the main body 1, and therefore the upper end of the motor case 4, and a cap-shaped transparent dust cover γ is attached to the upper end of the fan cover 6. are detachably connected, and their internal structure is shown in Figure 2.3.4.

In other words, the battery case 3 is open at both the top and bottom ends.
A pair of battery guide plates 84 and 82 are arranged facing each other in a removable manner, and for example, two batteries 9 and 9 can be removably inserted into the battery case 3 from below. It looks like this.

Further, a switch 11 is mounted in a switch mounting groove 10 formed in the peripheral wall of the battery case 3 so as to be able to slide up and down.

The motor case 4 has a lower end open and an upper end closed with an upper wall 12. A motor 13 is inserted into the motor case 4 from the lower side and fixed to the upper wall 12 with screws. It is.

The output shaft 14 of the motor 13 is connected to the upper wall 12 of the motor case 4.
It passes through a hole 15 provided in the center of the hole 15 and projects upwardly on the outside thereof.

On the other hand, an electrical insulating board 1 screwed to the bottom surface of the motor 13
6 has a positive and negative I pair of conductive electrode pieces 1γ1.
, 1T2, and a pair of conductive contact pieces 180, 182 are fixedly attached.

The motor case 4 is connected to the upper side of the battery case 3 by fitting its lower end to the upper end 3a of the battery case 3, which has a smaller outer diameter.

The bottom cover 5 has a plurality of circumferential protrusions 19 formed on its inner circumference, and a battery holding piece 20 made of an elastic conductive metal is fixed to the inner bottom cylinder.

Then, the bottom cover 5 is fitted onto the lower end 3b of the battery case 3, which has a smaller outer diameter, and turned slightly.
The protrusion 21 formed on the outer peripheral surface of the bottom cover 5
By fitting the protrusions 19 . . . , it can be removably fitted to the lower end of the battery case 3.

In this fitted state G, the bottom cover 5 closes the lower end opening of the battery case 3, and the battery holding piece 20
The two batteries ε, 9 are held down, and one electrode of these is electrically connected to each other, and at this time, the other electrode of both batteries 9, 9 is brought into contact with the electrode pieces 1γ1, 1γ2.

Like the motor case 4, the fan cover 6 has its lower end open and its upper end connected to the upper wall 22 (though it is closed by a trowel).
In order to intake and exhaust air, a circular intake port 24 is formed at the center of a funnel-shaped protrusion 23 formed protruding from the upper wall 22. In addition, a large number of elongated holes in the circumferential direction are formed in the upper half of the peripheral wall. Exhaust ports 25 are formed, and a filter (filter cloth) 26 is adhered to the inside of these exhaust ports 25, that is, to the upper half of the inner peripheral surface of the peripheral wall. However, a female thread 2γ is formed roughly in the lower half of the inner peripheral surface of the peripheral wall.

The fan cover 6, the motor case 4, the battery case 3, and the bottom cover 5 are each integrally molded from opaque synthetic resin.

Thus, the fan cover 6 can be freely attached to and removed from the upper end of the motor case 4 by screwing the female thread 2T on the inner peripheral surface of the lower end with the male thread 28 on the outer peripheral surface of the upper end of the motor case 4, which has a smaller outer diameter. To do this, the intake fan 29 is attached to the output shaft 14 of the motor 13 in advance, and this is positioned inside the fan cover 6.

The intake fan 29 is integrally molded from synthetic resin, and has a large number of blades 31 erected on the top surface of a disc 30, and the blades 31 .・
A cylindrical shaft 32, which is much longer than the length of the shaft 32, is formed upright.

In addition, a shaft hole 33 is formed in the center of the lower rib of the disc 30, and the upper end 32a of the shaft 32 is shaped like an oval shape having a flat vertical surface.

The intake fan 29 is attached to the output shaft 14 of the motor 13 by fitting its shaft hole 33 to the output shaft 14 of the motor 13, and by fitting the fan cover 6 to the motor case 4 as described above. The upper half of the shaft 32 projects outward and upward through the intake port 24 of the fan cover 6, and the inside of the fan cover 6 becomes a kind of dust collection chamber 34. It is something that exists.

Note that the output shaft 14 of the motor 13 and the shaft hole 33 of the intake fan 29 are not circular but square, such as hexagonal, to prevent the intake fan 29 from idling.

The dust cover 7 is integrally molded with transparent synthetic resin, and a part of the peripheral wall is removed from the lower end to the upper wall 35 to form a polishing port 36.
In addition, left and right protruding walls 3γ1 and 3T2 are formed extending from the left and right edges of the polishing port 36, and an inverted-shaped locking groove 38 is formed at a required portion of the lower periphery. .

Thus, this dust cover γ has its lower end fitted into the funnel-shaped protrusion 23 of the fan cover 6, and the locking groove 38 is integrally formed on the outer peripheral surface of the funnel-shaped protrusion 23. By locking the pin 39σζ, the upper end of the fan cover 6 can be fitted and removed freely and prevented from being removed inadvertently.
In this fitted state, the dust cover 7 covers the upper end 32a of the shaft 32 of the intake fan 29.
The rotary abrasive element 40, which is detachably attached to the rotary polisher 40, can be covered.

The cap 2 described above is able to cover the entire upper half of the fan cover 6 and the dust cover γ by being removably fitted to the upper half of the fan cover 6.

The rotating abrasive element 40 has an axial center 42 buried in the center of a circular core 41 made of an elastic material such as foamed resin or silicone rubber, a polishing sheet 43 wrapped around the outer peripheral surface of the core 41, and a axial center 42 embedded in the center of a circular core 41 made of an elastic material such as foamed resin or silicone rubber. A shaft hole 44 is formed in the neck.
By fitting the shaft hole 44 into the upper end 32a of the shaft 32, the rotary abrasive element 40 is attached to the shaft 32 so that it can be attached and detached freely but does not rotate idly. It protrudes outward from the polishing port 36.

Therefore, the rotary abrasive element 40 can be easily replaced by removing the dust shielding cover γ from the fan cover 6. Several types are available with different materials, and they can be used depending on the type of polishing.

Incidentally, the rotary abrasive element 40 shown in Fig. 2.3.4 uses leather as an abrasive sheet 43, and is used for polishing (polishing) the surface of the nail.

Further, the rotary abrasive element 40 shown in FIG.
The rotary abrasive 40 shown in FIG. This uses fine sandpaper, and is used to finish sharpen the tip of a toe that has been roughly ground with the one shown in Figure 5.

In addition, in this electric nail polisher, as shown in FIG. 7, a dish-shaped polish container 46 with a screw cap 45 is separately prepared, and as described above, a rotary polisher 40 made of leather is used. When polishing the nail surface, the polishing agent 41 in the polishing agent container 46 is applied to the nail surface.

This electric nail polisher has the above-mentioned configuration, and when the switch 11 is turned on and its conductive contact piece 48 is brought into contact with the pair of contact pieces 180 and 182 on the motor 13 side at the same time), when the motor 13 is driven, it rotates. The abrasive element 40 rotates at the same time as the intake fan 29 in the dust collection chamber 34, with a portion of the abrasive element 40 protruding from its abrasive port 36 within the dust shielding cover γ. 3. If leather is used as the abrasive sheet 43 as shown in Figure 4, polish it by applying the surface of a nail to its outer circumferential surface, or use sandpaper as shown in Figure 5 or 6. In the case where the polisher is used, the tip of the nail is applied to the outer circumferential surface of the polisher. It does not injure the skin during this process, and if there is an unevenness on the toe, the protrusion can be scraped off first, allowing the toe to be sharpened smoothly.

Further, the polishing powder generated from the polishing G is prevented from scattering to the surrounding area by the dust shielding cover γ, and is converged to the center (intake port 24) by the funnel-shaped protrusion 23, and is absorbed by the suction action of the intake fan 29. The dust is collected in the dust collection chamber 34 through the intake port 24, and is prevented from being discharged to the outside by the filter 26.

By removing the dust shielding cover 1 from the fan cover 6 and the fan cover 6 from the motor case 4, the inside of the dust shielding cover 7, the inside of the fan cover 6 (dust collection chamber 34), and the intake fan 29 can be easily cleaned. It is something that can be done.

Note that in the above embodiment, the bottom cover 5 is smaller than the battery case 3.
The battery can be replaced by removing the
As shown in the figure, a so-called rechargeable structure may be used to eliminate the need for battery replacement.

In other words, in the case shown in FIG. 8, a rechargeable battery and a transformer (not shown) are placed inside the battery case 3, while
At the lower end of the battery case 3, a pair of conductive plugs 49.
．． The battery in the battery case 3 can be charged by inserting the plug 50 into which the plug 492 can be inserted and retracted, and by inserting the plug 490, 49□ into an outlet for indoor indoor wiring of an AC a l OOV, for example. It is something.

Furthermore, the motor may be driven by an AC power source without using a battery.

As is clear from the above, the electric nail polisher of the present invention uses a motor to rotate a rotary abrasive element in which an abrasive sheet is wrapped around the outer circumferential surface of a circular core made of an elastic material such as foamed resin or silicone rubber. It sharpens by applying the nail to the circumferential surface of the abrasive, and the surface of the rotary abrasive can be deformed according to the applied pressure, and it does not hurt the skin. First, the protrusion can be scraped off, so the toe can be smoothed.

In addition, the rotary abrasive element is covered with a dust-blocking cover having a polishing port, and the intake fan that rotates integrally with the rotary abrasive element is formed with numerous exhaust ports on the surrounding wall, making the interior a dust collection chamber. It is covered with a fan cover, and a funnel-shaped protrusion with an intake port is formed on the earthen wall of the fan cover.The dust cover prevents nail polishing powder from scattering around the area, and the funnel-shaped protrusion allows the intake of air. The dust is converged into the mouth and can be efficiently collected in the dust collection chamber by the suction action of the suction fan.

Furthermore, since the filter is glued to the inside of the exhaust port of the fan cover, polishing powder that has entered the dust collection chamber will not be discharged to the outside.

Furthermore, the fan cover can be easily removed from the main body, the intake fan from the output shaft of the motor, and the dustproof cover from the fan cover. Easy to clean.

Furthermore, the dust cover can be removed from the fan cover as described above (as well as the rotating abrasive element can be removed from the shaft of the intake fan, so the rotating abrasive element can be easily replaced). It is something that can be done.
