Field of the Invention The present invention relates to a pencil sharpener having a cleaning function, and more particularly, to a pencil sharpener having a cleaning function capable of automatically cleaning foreign matter generated in a rotary cutter of a pencil sharpener by repeatedly will be.

In the conventional pencil sharpener, when the pencil is repeatedly cut, the foreign material is continuously inserted between the teeth of the rotary cutter that cuts the pencil. When the pencil sharpener is continuously left, the foreign material is stacked to obstruct the rotation operation of the rotary cutter, Or the rotary cutter is idle while the pencil is inserted.

In addition, when the pencil lead is broken inside the pencil sharpener in the process of cutting the pencil, it is caught between the saw blades of the rotary cutter, which also interferes with the rotation of the rotary cutter.

Therefore, there is an inconvenience that the pencil sharpener driving unit including the rotary cutter unit is detached from the main body to manually remove the foreign matter, the pencil lead, and the like between the saw blades of the rotary cutter with a tool such as a pin or a punch.

In particular, in the case of colored pencils, as shown in FIG. 1, since the shim with a high ductility is used in comparison with an ordinary pencil using a graphite shim, the colored pencil shim is more likely to break than the ordinary pencil and the foreign matter is generated more frequently, There is an inconvenience.

In addition, there is a risk that foreign matter may become dirty in the course of cleaning the rotary cutter, or accidents such as bending the rotary cutter in the process of cleaning may occur.
