FIVE-IN-ONE POLISHING HEAD

Abstract

A five-in-one polishing head includes a blade portion and a handle portion. The blade portion is shaped like a cone having a concave or planar top end. Angle teeth, thin teeth, medium-thin teeth, and thick teeth are sequentially distributed in a conical polishing head according to the tooth density. The angle teeth are located at the top of the conical polishing head in a circle. The thick teeth are located at the end of the blade portion. The center of the end of the blade portion is axially welded and fixed to one end of the handle portion. The conical polishing head is provided with regularly distributed straight lines or oblique lines on a surface from the angle teeth to the thick teeth. The shape of a right-handed groove on the surface is inverted trapezoidal, and the shape of a left-handed groove is triangular.

DETAILED DESCRIPTION

[0026] The present invention is further described below with reference to embodiments and the accompanying drawings.

Embodiment 1

[0027] A five-in-one polishing head of the present invention has five polishing functions: angle tooth polishing, thin tooth polishing, medium-thin tooth polishing, thick tooth polishing, and bidirectional polishing, is applicable to a nail polisher, and includes a blade portion and a handle portion.

[0028] Reference is now made to FIG. 1. FIG. 1 is a schematic view showing a structure in which a conical polishing head is provided with regularly distributed straight lines on a surface from angle teeth to thick teeth according to an embodiment of the present invention. As shown in the figure, a blade portion 1 is made of a tungsten steel material, and is shaped like a cone having a planar top end. Angle teeth 3, thin teeth 4, medium-thin teeth 5, and thick teeth 6 are sequentially distributed in a conical polishing head according to the tooth density. The angle teeth are located at the top of the conical polishing head in a circle. The thick teeth are located at the end of the blade portion. The length of the blade portion is 15.5 mm.

[0029] A handle portion 2 is made of a tungsten steel material, and is shaped like a cylinder having a diameter of 2.35 mm and a length of 25.4 mm. The center of the end of the blade portion is axially welded and fixed to one end of the handle portion. The conical polishing head is provided with regularly distributed straight lines or oblique lines on a surface from the angle teeth to the thick teeth. The shape of a right-handed groove on the surface is inverted trapezoidal, and the shape of a left-handed groove is triangular. An included angle between both sides of the groove is 30°. A total length of the conical polishing head is 41 mm. A top diameter of the angle teeth is 4.5 mm, and a bottom diameter of the thick teeth is 7.0 mm. The entire polishing head surface is smoothly transited. The shape of the angle teeth is an R angle having a size of R0.5. A conical angle of the cone is 20°. The angle teeth of the polishing head in the present embodiment have better affinity for nails and skin.

Embodiment 2

[0030] The present embodiment is the same as Embodiment 1 except that the blade portion 1 is made of a zirconia ceramic material and is shaped like a cone having a concave top end. The polishing head in the present embodiment has the function of enhancing heat dissipation.

Embodiment 3

[0031] In the present embodiment, the conical polishing head has an oblique line structure. FIG. 2 is a schematic view showing a structure in which a conical polishing head is provided with regularly distributed oblique lines on a surface from angle teeth to thick teeth according to an embodiment of the present invention. FIG. 3 is an enlarged view of part P in FIG. 2. The top end of the cone is a concave surface 7, so that nail grooves may be finely operated, and nail surface layers are more exquisite.

[0032] The present invention has substantial characteristics and remarkable technical progress. The five-in-one polishing head of the present invention is conical. A commonly used polishing head for exfoliation is a tool having an outer diameter of 1.6 mm. When the five-in-one polishing head is used, only an arc surface of a ball head corner contacts the skin, the contact area between the tool and the skin is small, and dead skin is not removed cleanly. The angle teeth R0.5 of the five-in-one polishing head may completely contact the skin for polishing, and the dead skin may be removed more thoroughly. The function of the angle teeth is to remove the dead skin at the edges of nails, the function of the thin teeth and the medium-thin teeth is to remove nail polish, and the function of the thick teeth is to remove the nail polish of the phototherapy nails. The five-in-one polishing head of the present invention may complete the entire manicure process with one knife.

[0033] The above embodiments illustrate rather than limit the present invention, and those skilled in the relevant art will be able to make various transformations or changes without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent technical solutions fall within the scope of the present invention as defined by the claims.
