Abstract:
1. A rechargeable type callus removal instrument comprising: a main body having a flaring tube shape with one side opened; a plate fitted with an inner circumference of an opening of the main body, thereby covering the opening; a motor connected with an inner lower part of the plate through a fastening member and equipped with a motor shaft having a semicircular sectional shape; a callus storage fitted around the motor shaft of the motor and rotated in accordance with rotation of the motor shaft, thereby collecting calluses separated from a user's foot therein; a filing cap covering an upper surface of the callus storage and removing the calluses of the user's foot as rotating along with the callus storage in contact with a callus surface of the foot; a guide member inserted in an upper surface of the plate and protruded in a cylindrical shape, forming a barrier at a predetermined distance from outer circumferences of the callus storage and the filing cap, such that the calluses being removed by the filing cap are collected in the callus storage without scattering about to the outside; a recharging device mounted to a lower part of the motor; an on/off device connected to the recharging device with one end thereof and to one side of the main body with the other end to control on and off states; wherein the recharging device comprises: a rechargeable battery; a protector covering an upper part of the rechargeable battery; a protection cover covering both sides and a lower surface of the rechargeable battery; a protection circuit mounted between a lower part of the protector and the upper part of the rechargeable battery, and connected to the on/off device so as to stably maintain predetermined voltage and current, thereby preventing overloading and the like; and an electrode protruded on the lower surface of tile protection cover downward with respect to the main body, with a rubber plate interposed between the electrode and the protection cover, and inserted in a power line to achieve recharging of power; wherein the electrode is embedded in an insulator medium connected by a fastening member, and an O-ring is inserted between an inner surface of a lower end of the main body and a lower surface of a flange part of the insulator medium so as to prevent entry of water.
