The present invention is intended to provide a clean writing surface by suctioning and storing an eraser spark generated at the same time by using an electric eraser when a pencil writing handwritten portion is to be erased, It is desirable to be compact.

1 to 5 in the drawings, when the electric eraser driving motor 30 is driven, the brush 27 and the buffer springs 23 induce the air suction, And a buffer cylindrical portion 26 in which a screw is formed in a repeated upper layer portion.

In the present invention, a brush (27) is constituted to form a space for allowing air to flow from the writing face by the rotational force of the suction impeller (10). This is because the eraser residue generated when the electric eraser is operated is a cylindrical And removes the minute residue of the remaining erasers that have not been sucked up, thereby sweeping the scraps of the remaining erasers. The shock absorbing cylindrical portion 26 that is vertically moved by the elasticity of the buffer spring 23 inserted into the buffer spring groove 24 formed in the lower body portion of the main body 20 is supported by the buffer spring 23 during operation of the electric eraser, The eraser residue is lifted up and stored in the eraser collecting cylinder 22. When the pressure of the eraser residue remaining on the floor surface is reduced by the pressing force of the handle, So that the eraser residue can be further sucked up through the space formed between the electric eraser and the buffer cylindrical portion 26. 4, the upper thread portion 20b is composed of a lower thread portion 20a of the upper body portion and a screw for assembling and disassembling the upper side thread portion, and the space of the lower side surface of the main body portion 20b is stored with the eraser residue rotated by centrifugal force And the eraser collecting container upper part 21 blocks the eraser residue collected by the centrifugal force from being prevented from flowing from the inside of the eraser collecting container 22 back into the air suction space 25 And the suction air generated by the rotation of the suction impeller (00) is cut off, so that the eraser residue can be collected stably. A buffer spring groove 24 into which the buffer spring 23 is inserted is formed at the lower end of the buffer spring groove 24 so as to prevent the buffer cylindrical portion 26 from being inserted into the buffer spring groove 24, The lower part is made up of screws. 3 has a motor mounting portion 40 for mounting the driving motor 30, a motor mounting portion cover 401 and a handle 50 coupled to the motor mounting portion 40. The motor mounting portion 40 includes a handle 50, And a body upper body engaging screw 20a which is engaged with a lower body engaging screw 20b and has an air outlet 20A capable of discharging the air sucked up and raised from the lower body portion of the body, An air outlet net 28 is formed to prevent the raised eraser residue from flowing out. A power switch groove 51, a power switch 51 and a battery 52a of the battery box 52 are electrically coupled to each other by a conductive line (not shown) in a case of the handle 50 connected to the body upper portion have.

The eraser mounting portion 12 and the integrated suction impeller 10 of FIG. 5 are connected to the rotary shaft 31 of the driving motor 30. A lower end of the eraser mounting portion 12 is connected to an eraser- A screw portion 13, a pressing female screw 14, and an eraser mounting groove 15.

In detail, the eraser mounting portion 12 and the integrated suction impeller 10 have a cylindrical groove formed along the length of the eraser mounting portion 12 to allow the cylindrical eraser 16 and 28 to be attached and detached, An eraser pressing screw portion 13 and a pressing female screw portion 14 are formed in the lower end portion of the mounting portion 12 so as to prevent the eraser from falling down after the eraser is inserted. The diameter is widened when the crimping female thread 14 is loosened by widening the diameter of the upper portion of the mounting portion 12 and the crimping female thread 14 is pressed and fixed to the eraser mounting portion 12 to prevent the eraser from escaping. In addition, in the center portion below the upper rotating plate 10 of the suction impeller 10, the raised eraser residue is constituted by the semicircular protrusion 17 so that the collecting can easily move to the main body wall in the eraser collecting cylinder 22, 10 are formed with curved blades with respect to the rotation center side, and are arranged at regular intervals. The rotary vane 11 is rotated by the driving of the motor to cause the lower air to rise by the whirlwind wind and the raised air is discharged along the air discharge port 20A so that the erroneous eruption that is accompanied by the centrifugal force and the gravity acts, So that the eraser debris collects in the eraser collecting box 22.

Hereinafter, the operation according to the present embodiment will be described. When the user touches the cylindrical eraser 16 of the electric eraser mounting portion 12 at the portion to be erased at the same time when the power switch 51 is pressed, the lower portion of the cylindrical eraser 16 And the writing surface are frictioned by the rotational force, and the portion to be automatically erased by the rotational force of the eraser mounting portion is deleted. The eraser remnants generated at this time are those in which the buffer cylinder 26 is brought into close contact with the writing surface due to the elasticity of the buffer spring 23 and the eraser remnants are not released to the outside by the tight buffer cylinder 26, The air in the lower part is sucked into the upper part due to the space between the brushes 27 constructed at the lower part of the part 26. As a result, the air sucked into the lower writing surface is raised in the direction of the air outlet 28 by the suction force of the suction impeller 10, and the eraser residue rising in accordance with the air flow of the air is moved by the centrifugal force and gravity, And collect in the collection box 202. Therefore, the handwritten portion is easily and conveniently erased through the electric eraser, and at the same time, the eraser residue scattered on the writing surface is collected in the eraser collecting box 22 to maintain the cleanliness of the writing surface.

Next, when the eraser collecting box 22 is filled with the eraser residue, the lower body assembling screw 20b assembled with the body upper body screw 20a is disassembled to disassemble the lower body eraser to empty the eraser residue filled in the eraser collecting case. When the eraser is completely consumed, the eraser pressing female screw 14 of the eraser mounting portion 12 is raised so that the eraser is worn and the eraser pressing female screw 14 is lowered so that the eraser is fixed to the eraser mounting portion 12 So that it can be pressed.
