Description

Technical Field

[0001] This utility model relates to an eraser shaving cleaner and a magnetic eraser. Background Technology

[0002] Magnetic erasers are a new type of stationery. Their structure typically includes an eraser body and a magnet connected to the eraser body. The eraser body and the magnet are connected by a plastic connector. The raw materials used to make the eraser body contain iron powder. The eraser shavings produced after erasing can be attracted by the magnet, making it easy to clean the eraser shavings on the paper. To keep the magnet clean, the eraser shavings attracted to it need to be cleaned frequently, but due to the influence of the magnet, the cleaning operation is relatively troublesome.

[0003] Chinese utility model patent discloses a magnetic eraser (CN218536159U), which includes an eraser body, a magnetic suction part, and a movable part. The eraser body is connected to one end of the magnetic suction part, and the movable part is movably connected to the other end of the magnetic suction part. When it is necessary to attract eraser shavings on the paper, the movable part is moved to a position close to the magnetic suction part, and the magnetic force is used to attract the eraser shavings to the outer surface of the movable part. When it is necessary to clean the eraser shavings on the movable part, the movable part is moved away from the magnetic suction part, so that the distance between the eraser shavings and the magnetic suction part increases, the magnetic force on the eraser shavings is weakened, and the eraser shavings are made easier to detach from the movable part.

[0004] In the aforementioned patented solution, in order to maintain the magnetic adsorption effect on eraser shavings and prevent them from falling onto the desktop or paper, the eraser shavings on the movable part need to be cleaned into the trash can frequently. The cleaning process requires pushing and pulling the movable part, which is relatively troublesome to use. Summary of the Invention

[0005] This invention provides an eraser shavings cleaner that can conveniently clean up eraser shavings that have been magnetically attracted.

[0006] The eraser shavings cleaner provided by this utility model includes a base shell with an inner cavity, a magnetic block disposed in the inner cavity of the base shell, and an adsorption surface at the front end of the base shell. A slider capable of sliding along the front-rear direction of the base shell and a spring for driving the slider to return to its original position towards the front end of the base shell are disposed in the inner cavity of the base shell. The magnetic block is disposed on the slider. After the slider moves towards the front end of the base shell, the magnetic block is positioned close to the adsorption surface. The slider includes a transmission part extending outward from the side of the base shell. An outer cover is movably fitted onto the base shell. The outer cover and the transmission part form a pushing engagement. The action of the outer cover fitting onto the base shell drives the slider to move backward. When the outer cover is fitted onto the base shell, a space is left between the inner wall of the bottom of the outer cover and the adsorption surface, which can be used to collect eraser shavings.

[0007] When the outer cover is not attached, the slider is forward, and the magnetic block is close to the adsorption surface. Rubber shavings (containing iron powder) can be adsorbed through the adsorption surface. When it is necessary to clean the rubber shavings on the adsorption surface, the outer cover is attached to the base shell. During the attachment process, the slider is pushed backward by the transmission part, which moves the magnetic block away from the adsorption surface. After the magnetic force on the rubber shavings weakens, they will fall to the bottom of the outer cover. At this time, the outer cover can be pulled out of the base shell, and the collected rubber shavings can be poured out through the outer cover. During the removal of the outer cover, the slider is pushed forward by the spring to reset, which does not require manual operation and is relatively convenient.

[0008] Furthermore, a positioning protrusion and a positioning groove are provided between the outer cover and the base shell to keep the outer cover fitted onto the base shell. This can position the outer cover when it is fitted onto the base shell, preventing the outer cover from being pushed off the base shell by the spring and making it convenient to carry.

[0009] Furthermore, the base shell includes a base and a cover. The front end of the base includes a first annular convex wall, and through grooves are symmetrically arranged on the left and right sides of the front end of the first annular convex wall. The rear end of the cover includes a second annular convex wall that is inserted and positioned inside the first annular convex wall. The inner cavity is formed by the inner holes of the first and second annular convex walls. The left and right sides of the slider are provided with transmission parts. The transmission parts are movably inserted through the through grooves on the outside of the inner cavity. The slider can be driven by a spring to move forward to the inside of the second annular convex wall. This structural design facilitates the assembly of the spring and the slider, and the second annular convex wall prevents rubber debris from entering the inner cavity along the front of the through groove during use.

[0010] Furthermore, the upper and lower sides of the second annular convex wall and the corresponding areas of the upper and lower front sides of the first annular convex wall are positioned by a snap-fit ​​positioning structure. Due to the setting of the through groove, the upper and lower front sides of the first annular convex wall have better elasticity in the opening and closing directions. Setting the snap-fit ​​positioning structure here facilitates the disassembly and assembly of the cover.

[0011] Furthermore, the transmission part includes an extension arm slidably disposed in the through groove, a connecting rib connecting the rear end of the extension arm and the rear end side of the slider body, and a protrusion connecting the front end of the extension arm. The inner rear end of the outer cover is provided with a notch into which the protrusion can be inserted and moved. The abutting surface at the front end of the notch forms a pushing fit with the protrusion. This structural design allows the outer cover to push the protrusion to move only after it is fitted into a certain position, which can reduce the movement stroke of the slider.

[0012] Furthermore, a support column is provided at the rear end of the slider, and a positioning groove is provided at the corresponding position on the bottom inner wall of the inner cavity to form a movable insertion fit with the support column. The front end of the spring is sleeved and positioned on the support column, and the rear end of the spring is inserted and positioned in the positioning groove, which can improve the positioning effect of the spring and ensure the stability of its elastic force direction.

[0013] In addition, this utility model also provides a magnetic eraser with the above-mentioned eraser shavings cleaner, and also includes an eraser body that is connected to the base shell. The raw material of the eraser body contains metal powder that can be magnetically attracted. By combining the eraser body and the eraser shavings cleaner together, the eraser and the cleaning function can be realized at the same time, making the product convenient to carry and use.

[0014] Furthermore, the base shell is connected to a sleeve shell, one end of which is fixedly connected to the base shell, and the other end of which has an opening connected to its interior. The rubber body is movably disposed inside the sleeve shell, and the sleeve shell is provided with a drive device for pushing the rubber body to extend and retract along the direction of the opening and for positioning the pushed rubber body. When in use, the drive device pushes the rubber body out of the opening and keeps it in the extended position for convenient use. When not in use, it can be driven to retract back into the sleeve shell to prevent the rubber body from breaking due to external force. Attached Figure Description

[0023] Examples of embodiments of the magnetic eraser of this utility model Figure 1-8The device includes a rubber shaving cleaner, comprising a base shell with an inner cavity 10 and a rubber body 2 connected to the base shell. The rubber body 2 is made of iron powder. A sleeve 3 is connected to the base shell; one end of the sleeve 3 is fixedly connected to the base shell, and the other end of the sleeve 3 has an opening connecting to its interior. The rubber body 2 is movably disposed inside the sleeve 3. The sleeve 3 is equipped with a drive device 4 for pushing the rubber body 2 to extend and retract along the opening and for positioning the pushed rubber body 2. In use, the drive device pushes the rubber body 2 out of the opening and holds it in the extended position. For easy erasing, the eraser body 2 can be retracted into the housing 3 when not in use, preventing breakage due to external force. The drive device 4 is a common structure in existing erasers with a retractable eraser body 2. Its working principle is as follows: pressing the push button on the drive device 4 unlocks the drive device 4 from the housing 3, and the push button pushes the drive device 4 and the eraser body 2 together, achieving the retractable movement of the eraser body 2. When the push button is released, the push button resets under the action of the spring in the drive device 4, and relocks the drive device 4 and the housing 3, preventing the eraser body 2 from retracting into the housing 3 on its own when erasing. Specifically, the locking and unlocking of the drive device 4 and the housing 3 is achieved through the cooperation of a toothed array on the housing 3 and a movable latch that is linked to the push button and the spring.

[0024] Regarding the eraser shavings cleaner, a magnetic block 5 is installed in the inner cavity 10 of the base shell. The front end of the base shell has an adsorption surface 121. A slider 6, capable of sliding along the front-rear direction of the base shell, and a spring 8 for driving the slider 6 to return to its original position towards the front end of the base shell are also installed in the inner cavity 10 of the base shell. The magnetic block 5 is mounted on the slider 6. After the slider 6 moves towards the front end of the base shell, the magnetic block 5 is positioned close to the adsorption surface 121. The slider 6 includes a transmission part 61 extending outward from the side of the base shell. An outer cover 9 is movably fitted onto the base shell. The outer cover 9 and the transmission part 61 form a pushing engagement. The action of the outer cover 9 fitted onto the base shell pushes the slider 6 to move backward. When the outer cover 9 is fitted onto the base shell, a space is left between the bottom inner wall 91 of the outer cover 9 and the adsorption surface 121. This space can be used to collect eraser shavings. Figure 3 As shown.

[0025] When the outer cover 9 is not attached, the slider 6 is forward, and the magnetic block 5 is close to the adsorption surface 121. Rubber shavings (containing iron powder) can be adsorbed through the adsorption surface 121. When it is necessary to clean the rubber shavings on the adsorption surface 121, the outer cover 9 is attached to the base shell. During the attachment process, the slider 6 is pushed backward by the transmission part 61, so that the magnetic block 5 is away from the adsorption surface 121. After the magnetic force on the rubber shavings weakens, they will fall to the bottom of the outer cover 9 (i.e., the bottom inner wall 91). At this time, the outer cover 9 can be pulled out from the base shell again, and the collected rubber shavings can be poured out through the outer cover 9. During the process of pulling out the outer cover 9, the slider 6 is pushed forward by the spring 8 to reset, which does not require manual operation and is relatively convenient.

[0026] The outer cover 9 and the base shell are provided with a positioning protrusion 111 and a positioning groove 92 for keeping the outer cover 9 fitted onto the base shell. This can position the outer cover 9 when it is fitted onto the base shell, preventing the outer cover 9 from being pushed off the base shell by the spring 8, and making it convenient to carry the outer cover 9.

[0027] The base shell includes a base 11 and a cover 12. The front end of the base 11 includes a first annular convex wall 112. The front end of the first annular convex wall 112 is symmetrically provided with through grooves 113 on the left and right sides. The rear end of the cover 12 includes a second annular convex wall 122 that is inserted and positioned inside the first annular convex wall 112. The inner cavity 10 is formed by the inner holes of the first annular convex wall 112 and the second annular convex wall 122. The slider 6 is provided with a transmission part 61 on both the left and right sides. The transmission part 61 is movably inserted through the through grooves 113 on the outside of the inner cavity 10. The slider 6 can be driven by the spring 8 to move forward to the inner side of the second annular convex wall 122. This structural design facilitates the assembly of the spring 8 and the slider 6. Furthermore, due to the obstruction of the second annular convex wall 122, it can prevent rubber shavings from entering the inner cavity 10 along the front of the through grooves 113 during use.

[0028] The upper and lower sides of the second annular convex wall 122 and the corresponding areas of the upper and lower front sides of the first annular convex wall 112 are positioned by a snap-fit ​​positioning structure. Due to the setting of the through groove 113, the upper and lower front sides of the first annular convex wall 112 have better elasticity in the opening and closing directions. Setting the snap-fit ​​positioning structure here facilitates the disassembly and assembly of the cover 12. The snap-fit ​​structure includes a slot 1121 set on the first annular convex wall 112 and a buckle 1221 set on the second annular convex wall 122.

[0029] The transmission part 61 includes an extension arm 611 slidably disposed in the through groove 113, a connecting rib 612 connecting the rear end of the extension arm 611 and the rear end side of the slider 6 body, and a protrusion 613 connected to the outer side of the front end of the extension arm 611. A gap is left between the extension arm 611 and the body of the transmission part 61, which allows the second annular protrusion 122 to be inserted and moved. The inner rear end of the outer cover 9 is provided with a notch 93 for the protrusion 613 to be inserted and moved. The abutment surface 931 located at the front end of the notch 93 forms a pushing fit with the protrusion 613. This structural design allows the outer cover 9 to push the protrusion 613 to move only after it is fitted into a certain position, which can reduce the movement stroke of the slider 6 and make the structure more compact.

[0030] The rear end of the slider 6 is provided with a support column 62, and the bottom inner wall of the inner cavity 10 is provided with a positioning groove 114 that is movably inserted and engaged with the support column 62. The front end of the spring 8 is sleeved and positioned on the support column 62, and the rear end of the spring 8 is inserted and positioned in the positioning groove 114, which can improve the positioning effect of the spring 8 and ensure the stability of its elastic force direction.

[0031] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
