Abstract

PURPOSE: An eraser on which a small vacuum cleaner is attached is provided to prevent contamination and to improve the convenience for taking a note by immediately removing migwish when using an eraser. CONSTITUTION: An eraser on which a small vacuum cleaner is attached comprises an air inlet, an air outlet(10), a driving motor, a sucking fan, and a migwish collector. The sucking fan rotates by a torque of a driving motor. The migwish collector receives migwish flowing in by a sucking force generated by rotation of the sucking fan through the air inlet. Air is discharged through the air outlet after collecting the migwish.

Description

Eraser attachment style guard post style vacuum cleaner}

The present invention relates to an ultra-small vacuum cleaner attached to an eraser, and in particular, when using a pencil or the like to modify it, an eraser attached type for convenience of writing by using an eraser and at the same time removing eraser powder to clean up the surroundings It relates to a micro vacuum cleaner.

Recently, various writing supplies have been developed to meet consumer's taste, but pencils are the most basic writing supplies, and their use is constantly being continued.

The advantage of a pencil is that it can be easily modified, but inevitably, an eraser powder is issued during the erasing process and if it is not cleaned from time to time, it contaminates the work environment such as paper and the surrounding environment.

Thus, in order to remove the eraser powder from time to time while using the pencil and the eraser, there is a disadvantage in that it takes a great inconvenience, such as stopping writing and cleaning separately.

The present invention has been made to solve the above problems, when writing using a pencil or the like when the wrong number of eraser and at the same time using the eraser to remove the eraser powder to clean the surroundings to facilitate the writing of the eraser attached Its purpose is to provide a miniature vacuum cleaner.

According to the object of the present invention, the air inlet 13 for the inlet of air and the air outlet 10 for the discharge of air is formed, the drive motor 6 for generating a rotational force, the rotational force of the drive motor 6 And an eraser powder collecting container (8) for accommodating the eraser powder introduced by the suction force generated by the rotational operation of the suction fan, and the suction force according to the rotational force of the drive motor (6). To generate an eraser powder through the air suction port 13 to collect the eraser powder collection container 8, and the introduced air is discharged through the air discharge port 10. A cleaner is provided.

According to the present invention, while using an eraser-type micro vacuum cleaner, the eraser is immediately removed while using the eraser to prevent contamination and improve the convenience of writing.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing the configuration of an eraser-mounted micro vacuum cleaner according to a first embodiment of the present invention.
Figure 2 is a view showing a state using a micro vacuum cleaner attached to the eraser of Figure 11;
3 is a block diagram showing an eraser-mounted ultra-small vacuum cleaner according to a third embodiment of the present invention.

FIG. 1 is a use state diagram showing a state of using an eraser-mounted ultra-small vacuum cleaner according to FIG. 1.

Eraser-Type Ultra-Vacuum Cleaner The user can use a pencil and erase it with an eraser (2) mounted on top of the main body (1) whenever correction is required, and then operate the drive motor (6) inside the main body (1). As shown, the switch 15 installed on the eraser powder removing cap is pressed against the bottom surface.

As soon as the switch 15 is pressed to the floor, the power of the battery 4 is supplied to the driving motor 6 so that the driving motor 6 starts to rotate. Accordingly, the suction fan 7 rotates to operate the air. Air is sucked in through the inlet 13. The air sucked through the air inlet 13 opens the suction tube 14 toward the upper side of the main body 1, passes through the eraser powder collecting container 8, and is discharged out of the main body 1 through the air outlet 10. Will be.

As the air is sucked through the air inlet 13, the eraser powder on the bottom is also swept into the air to be introduced into the air inlet 13. The eraser powder introduced through the air inlet 13 passes through the air inlet passage, through a gate in which the suction tube 14 of the eraser powder removing cap is installed, and into the eraser powder collector 8 inside the bottom of the main body 1. Will be collected. At this time, the spacer 9 has a sufficient space on the side as shown in Figure 1 does not interfere with the flow of air.

On the other hand, when the user lifts the ultra-small vacuum cleaner with an eraser and presses the switch 15, the power supply from the battery 4 to the driving motor 6 is stopped and the rotation operation of the suction fan 7 is stopped. As the rotation operation is stopped, the inflow of air through the air inlet 13 is also stopped.

When the inflow of air through the air inlet 13 is stopped, the suction tube 14 of the flexible material installed in the eraser powder removing cap is closed, and collected by the eraser powder collecting container 8 by the inflow force of air. The eraser powder will fall in the direction of the eraser powder removal cap. Eraser powder falling from the eraser powder collector 8 in the direction of the eraser powder removing cap is blocked by the closed suction tube 14 and is accumulated on the suction tube 14 without falling further toward the air inlet 13.

The eraser powder accumulated between the eraser powder collecting container 8 and the suction tube 14 may be removed when the user separates the eraser powder removing cap from the main body 1.

FIG. 2 shows a state in which the eraser-mounted micro vacuum cleaner of FIG. 11 is used.

According to the eighth embodiment of the present invention, the eraser-mounted micro-vacuum cleaner uses a pencil to erase the eraser whenever it needs to be modified, and then turns on the switch 15 of the eraser-mounted micro-vacuum cleaner. Power is supplied to the integrated fan is rotated by the rotation operation of the drive motor, the air is introduced into the air inlet (13) by the rotation of the integrated fan. The inflow of air causes the eraser powder to flow in, and the eraser powder introduced into the air inlet 13 is collected in the eraser powder removing cap and the eraser powder collector, and at the same time, the eraser powder is filtered through a plurality of eraser filter sieves. You lose. The introduced air is eraser powder collector and eraser powder collector and eraser powder

It enters into the secondary air inlet via a strainer, and is discharged out through a plurality of air outlets (10).
