Description

Technical Field

[0001] The utility model relates to the technical field of stationery, more specifically to a magnetic eraser. Background Art

[0002] In the process of erasing pencil writing, eraser waste will be generated. The usual way to deal with the eraser waste is to blow it off directly with the mouth or brush it off with the hand, but this will cause the eraser waste to scatter all over the floor, affecting indoor hygiene. In the prior art, there is also a method of collecting the eraser waste and then centrally processing it, which can avoid the sanitation problem caused by the scattering of eraser waste, but the corresponding eraser product is more complicated to use, resulting in a poor user experience.

[0021] Embodiment 1:

[0022] like Figures 1 to 3 As shown in the figure, the magnetic eraser of the utility model comprises an outer shell 1, one end of the outer shell 1 is open, and the other end is provided with a base 4, a magnetic eraser body 3 is provided in the outer shell 1, a slide groove 1-1 is provided on the outer shell 1, and a push-twist 2 is provided in the slide groove 1-1, and the push-twist 2 is in contact with or connected to the magnetic eraser body 3. When the push-twist 2 is pushed along the slide groove 1-1, the push-twist 2 can slide along the slide groove 1-1 and push the magnetic eraser body 3 to extend from the open end of the outer shell 1, and pencil writing can be erased at this time, and eraser waste is generated after the magnetic eraser body 3 erases the pencil writing.

[0023] The base 4 is also provided with a chip collecting cover 5, a rotating shaft 5-1 is provided on the chip collecting cover 5, a rotating shaft hole is provided on the base 4, the rotating shaft 5-1 is inserted into the rotating shaft hole and is axially limited by the rotating shaft hole, the chip collecting cover 5 can rotate and translate around the rotating shaft 5-1, the chip collecting cover 5 can rotate and translate to cover the end face of the base 4, and can also rotate and translate to separate from the end face of the base 4. A limiting groove 4-1 is provided on the end face of the base 4, and a limiting convex point 5-2 is provided on the inner side of the chip collecting cover 5. When the chip collecting cover 5 rotates and translates around the rotating shaft 5-1 to cover the end face of the base 4, the limiting convex point 5-2 slides into the limiting groove 4-1 and is limited by the limiting groove 4-1; when the chip collecting cover 5 rotates and translates around the rotating shaft 5-1 to separate from the end face of the base 4, the limiting convex point 5-2 can slide out of the limiting groove 4-1.

[0024] A magnetic block 4-2 is arranged on the end surface of the base 4, and the magnetic block 4-2 can magnetically attract the magnetic eraser body 3 and the eraser waste generated after the magnetic eraser body 3 erases the pencil writing. A chip collecting area 5-3 and a lifting rib 5-4 are arranged on the outer side of the chip collecting cover 5, and the lifting rib 5-4 surrounds the outer side of the chip collecting area 5-3 to raise the enclosure of the chip collecting area 5-3, thereby increasing the inner space of the chip collecting area 5-3. When the chip collecting cover 5 covers the end surface of the base 4, the back side of the chip collecting area 5-3 is opposite to and in contact with the magnetic block 4-2. At this time, the magnetic block 4-2 can magnetically attract the eraser waste through the chip collecting cover 5, so that the eraser waste is collected in the chip collecting area 5-3. When the chip collecting upper cover 5 separates from the end face of the base 4, the back side of the chip collecting area 5-3 is no longer relative to the magnetic block 4-2, and the waste scraps of the eraser in the chip collecting area 5-3 fall off one after another because they are no longer subject to the magnetic attraction, so that the waste scraps of the eraser are conveniently concentrated and removed in the trash can. In this way, the collection and removal operation of the waste scraps of the eraser are simple and convenient, and it is easy to get started.

[0025] Embodiment 2:

[0026] The difference between the magnetic eraser of this embodiment and the embodiment 1 is that the chip collecting cover 5 is hinged with the base 4, that is, the chip collecting cover 5 and the base 4 are connected by hinges (not shown), the chip collecting cover 5 can rotate relative to the base 4 to close with the base 4 so that the chip collecting cover 5 covers the end surface of the base 4, and the chip collecting cover 5 and the base 4 can also rotate to open so that the chip collecting cover 5 and the end surface of the base 4 are separated. A limiting groove 4-1 is provided on the end surface of the base 4, and a limiting convex point 5-2 is provided on the inner side surface of the chip collecting cover 5, and the limiting convex point 5-2 can be snap-connected with the limiting groove 4-1.

[0027] When it is necessary to collect eraser waste, the chip collecting cover 5 and the base 4 are rotated and closed, so that the chip collecting cover 5 covers the end surface of the base 4, the back side of the chip collecting area 5-3 is opposite to and in contact with the magnetic block 4-2, the limiting protrusion 5-2 is inserted into the limiting groove 4-1 and is snap-connected with the limiting groove 4-1. At this time, the magnetic block 4-2 can magnetically absorb the eraser waste through the chip collecting cover 5, so that the eraser waste is collected in the chip collecting area 5-3.

[0028] When it is necessary to remove the eraser waste, the chip collecting cover 5 and the base 4 are rotated and opened, and the chip collecting cover 5 is forced to separate from the end face of the base 4, the limiting protrusion 5-2 withdraws from the limiting groove 4-1, and the back of the chip collecting area 5-3 is no longer in contact with the magnetic block 4-2. At this time, the eraser waste in the chip collecting area 5-3 falls off one after another because it is no longer affected by the magnetic attraction force, so it is convenient to collect and remove the eraser waste into the trash can.

[0029] The above are only specific embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. If the present invention is modified or replaced by equivalents without departing from the spirit and scope of the present invention, they should be included in the protection scope of the claims of the present invention.
