Embodiment Construction

[0009] Below in conjunction with accompanying drawing, embodiment of the present invention is further described:

[0010] Such as figure 1 Shown, a kind of eraser with chip blowing function comprises eraser (1), blowing rubber ball (2), and blowing rubber ball is connected with eraser, is characterized in that:

[0011] a. There is a slender cylindrical hole in the center of the eraser, which runs through the axis of the eraser and can pass compressed gas.

[0012] b. The inflatable rubber ball is a hollow structure for storing air.

[0013] It works like this:

[0014] Erasing trace working route: lightly press the head of the eraser on the trace to be erased, and rub back and forth.

[0015] Air blowing chip removal work route: Align the rubber head hole with the waste rubber chips, and quickly squeeze the blowing rubber ball with your fingers.

Abstract

The invention relates to an eraser with a scrap blowing function. The eraser comprises an eraser body and a blowing rubber ball, a long and thin cylindrical hole is formed in the center of the eraser body and penetrates through the axis of the eraser body, the rubber ball is of a hollow structure used for storing air, and the eraser body is connected with the rubber ball. When the eraser is used, compressed air is generated by squeezing the blowing rubber ball, and waste rubber scraps are blown away. The eraser has the advantages of being simple in structure, convenient to operate and use and low in manufacturing cost, and is very suitable for being widely used and popularized.

Description

technical field [0001] The invention belongs to the technical field of stationery production, in particular to an eraser with a chip blowing function. Background technique [0002] When people use an eraser to wipe, they will produce a lot of fine waste rubber shavings, which are very difficult to deal with. Usually, they are wiped with paper towels, or blown off with their mouths, or use a self-priming eraser to remove the waste. Eraser crumbs are sucked away, but it is easy to wipe the written words when wiping with paper, and it is easy to confuse the eyes when blowing with the mouth. The eraser with self-priming function has a complicated structure and is more expensive. Eraser with crumb function. [0003] The eraser can be blown to remove debris after wiping with the eraser, has the advantages of simple structure, convenient operation and use, and low manufacturing cost, effectively solves the above-mentioned problems, and can be widely popularized and used.
