The present invention relates generally to a nail polishing apparatus, and more particularly, to a rechargeable nail polishing device that is used to grind cured gel on fingernails or toenails.
Manicure is a procedure for decorating to beautify fingernails or toenails. When working in nail art, a gel is usually applied to the fingernail or toenail, and then the gel is irradiated and cured by ultraviolet light generated by an ultraviolet curing device on the nails. After the gel is cured, the manicurist uses a wired nail polishing apparatus to grind the cured gel on the nails for polishing. In addition, during the removal process, the manicurist will also use a wired nail polishing apparatus to remove the cured gel on the nails in order to recreate the new nail art.
A wired nail polishing apparatus extends through a power cord to plug into a remote power outlet location to obtain a source of electrical power.
However, when a manicurist uses a wired nail polishing apparatus for nail work, the apparatus will be constantly interfered by the presence of the power cord and reduce the efficiency of nail art work.
Furthermore, people who shuttle on the path of the power cord of the wire d nail polishing apparatus may be tripped by the power cord, which is dangerous and may suddenly unplug the power cord from the power outlet to say the least.

From the perspective of the assembly, the rechargeable battery 24 may be a non-removable internal battery or a detachable battery. From the perspective of the rechargeable chemical material, the rechargeable battery 24 may be a nickel-hydrogen battery, a lithium battery, or a battery made of other rechargeable chemical materials. In addition, the number of rechargeable batteries 24 may depend on the internal volume of the casing 21, and the number is at least one.
A switch speed knob 251 is disposed on the outer side of the base 25, and the switch speed knob 251 is electrically connected to the second control unit 28. The outer side of the base 25 has a switch indicator window 252 above the switch speed knob 251. The inner side of the base 25 is disposed with a switch indicator light (not shown). The position of the switch indicator light corresponds to the position of the switch indicator window 252, and the switch indicator light is electrically connected to the second control unit 28. The outer side of the base 25 is disposed with a rotational speed indicator portion 253 on the side of the switch indicator window 252. The rotational speed indicator portion 253 is for displaying the rotational speed of the drive shaft 231.
The operation mode of the rechargeable nail polishing apparatus of the present invention will be described below with reference to the drawings.
First, the grinder 20 is taken out from the charging stand 10. The grinding member 30 is taken out, passes through the through hole 22211 of the socket 2221 and is fixed in the clamping portion 22221 of the chuck 2222. The locking member 2211 is rotated such that the quick release member 2212 can secure the grinding member 30 to the chuck 2222. The switch speed knob 251 is rotated such that the second control unit 28 turns on the drive shaft 231 of the driving member 23, turns on the switch indicator light, and turns on the illumination units 223. The user can see through the switch indicator window 252 that the switch indicator light is illuminated, and that the driving member 23 is turned on. The drive shaft 231 of the driving member 23 further drives the quick release member 2212 and the chuck 2222 to rotate synchronously, whereby the grinding member 30 begins to rotate. The user can adjust the rotational speed of the drive shaft 231 by rotating the switch speed knob 251, and the rotational speed indicator portion 253 can show the rotational speed of the drive shaft 231. At this point, the user can hold the grinder 20, align the grinding member 30 with the fingernail or toenail to modify or remove the cured gel on the fingernail or toenail. During the grinding process, the illumination units 223 are capable of providing sufficient light to allow the user to clearly see the cured gel on the fingernails or toenails.
During the operation, if the user wants the grinding member 30 to rotate forward, the steering switching button 212 must be moved up to the top end of the long slot 211 in accordance with the instruction of the forward rotation indicating portion 213, and the second control unit 28 controls the drive shaft 231 to rotate forward, and the drive shaft 231 further drives the quick release member 2212 and the chuck 2222 to rotate forward synchronously, so that the grinding member 30 rotates forward synchronously. If the user wants the grinding member 30 to rotate reversely, the steering switching button 212 must be moved down to the bottom end of the long slot 211 as instructed by the reverse rotation indicating portion 214, and the second control unit 28 controls the drive shaft 231 to rotate reversely. The drive shaft 231 further drives the quick release member 2212 and the chuck 2222 to rotate reversely in synchronization so that the grinding member 30 rotates reversely synchronously.
The user can see that the power indicator lights are turned on or off through the power indicator window 215. When the power of the rechargeable battery 24 is sufficient, all of the four power indicator lights are illuminated; as the grinder 20 is used, the amount of the power of the rechargeable battery 24 will gradually decrease, and the power indicator lights are sequentially turned off one by one.
After the power of the rechargeable battery 24 is completely exhausted, the drive shaft 231 stops rotating, and the quick release member 2212 and the chuck 2222 stop rotating synchronously, so that the grinding member 30 stops rotating synchronously, the switch indicator lights and the illumination unit 223 are all extinguished. Alternatively, the user can rotate the switch speed knob 251 so that the second control unit 28 controls the drive shaft 231 of the driving member 23 to stop rotating, and the switch indicator lights and the illumination units 223 are all extinguished.
