The present invention discloses a nail grinding pen, which comprises a pen barrel, a motor, and an inner body. The inner side of the pen barrel has a receiving space, and an opening connected to the receiving space provided on one side of the pen barrel. The motor is arranged in the receiving space, and driven by electric power to rotate the rotating shaft. The inner body is connected to the rotating shaft, and one end of the inner body facing the opening has a gripper for fixing a grinding head, so that the motor is able to drive the grinding head into rotation by rotating the gripper.

Disclosed is a portable electric nail file, and a system comprising an electric nail file handpiece having a motor and a power unit having a rechargeable battery for supplying power to said electric nail file. The power unit has manual digital control interface in the form of a click wheel to enable a user to control the direction and speed of the motor of the electric nail file. The interface communicates to a processor for controlling the operation of the electric nail file the processor executing stored software instructions. The device and system include a communication element for receiving signals from a foot pedal by low power radio signal control of the direction and speed of the electric nail file motor. A docking cradle engages the power unit and through metal contacts is operable to recharge the battery of the power unit. The cradle also incorporates display indicating speed and direction.

Provided is an electric grinder. The grinder includes a swing motor and a grinding head driven by the swing motor. The swing motor further includes a U-shaped yoke, four permanent magnets and a swing arm. Alternating magnetic poles can be generated at end faces of the two legs under control of a control circuit. The four permanent magnets are sequentially distributed on the same circumference of a circle having the fulcrum as a center. The control circuit generates alternating pulses with adjustable pulse widths, which change the moving direction of the permanent magnets alternately, so that the permanent magnets move back and forth. The swing arm drives the grinding head to reciprocate at a high speed with small swinging amplitude, thereby cleaning the body surface (skin, nails or the like) of living bodies including human beings and animals.

A multi-movement cosmetic assembly includes a housing defining an interior; a drive system disposed within the housing; a sleeve received within the housing; and a drive shaft positioned in the sleeve. The drive system is operably coupled to the sleeve and the drive shaft such that actuation of the drive system causes (i) the sleeve to move laterally back and forth to oscillate relative to the housing, and (ii) the drive shaft to rotate relative to the housing.

A nail lamp station includes a base lamp assembly and a handheld nail care tool for providing an additional nail care function. The base lamp assembly includes a station housing having a light cavity capable of receiving multiple fingernails therewithin, and a main light source supported within the light cavity for drying nail polishes on the fingernails at the same time within the light cavity. The handheld nail care tool includes a detachable lamp pen detachably coupled at the station housing, wherein the detachable lamp pen includes an elongated pen body and a point light source provided at a light end of the pen body for drying the nail polish on one single particular fingernail.

An electrically-powered nail cutting apparatus includes a housing having a front face and a rear face, two sides, a top and a bottom. The front face of the housing having an open slot at least 0.5 mm in height and between 0.7 cm and 4 cm in width, the slot having a front-facing opening and a rear-facing opening. Within the housing and proximal to the rear-facing opening is a vertically translating nail-cutting blade plate associated with an electric motor that is configured to translate the nail-cutting blade plate consecutively down and up. The blade plate is a solid material having an opening therein, wherein the top of the opening comprises a cutting blade with a cutting edge within the opening such that the cutting edge is adjacent the rear-facing element.
