A paper shredder

Abstract

This utility model provides a paper shredder, including a base with a paper scrap bin movably connected to it. A vibration module, comprising an electromagnetic vibrator, a magnet, and an elastic element, is also provided within the base. The elastic element supports the paper scrap bin and allows it to return to its original position. One of the electromagnetic vibrator and the magnet is located within the base, while the other is connected to the paper scrap bin and positioned opposite the vibrator within the base. When energized, the electromagnetic vibrator periodically attracts the magnet. This attraction causes the paper scrap bin to move towards the base and the elastic element to deform elastically. When the electromagnetic vibrator and magnet are no longer attracted, the elastic element rebounds and drives the paper scrap bin back to its original position. In this paper shredder, the paper scrap bin vibrates under the action of the vibration module, causing the paper scraps to automatically spread out evenly within the bin.

Description

Technical Field

[0001] This utility model relates to the technical field of paper shredders. Background Technology

[0002] After shredding, the paper scraps don't automatically spread out in the scrap bin; instead, they accumulate into a cone shape. As the amount of scraps increases, the base area of ​​this cone grows, gradually filling the bottom of the scrap bin. The top of the cone also rises, approaching the detection range of the full-paper sensor, causing it to issue a full-paper alarm prematurely, necessitating manual intervention to continue shredding. However, even when the full-paper sensor issues the alarm, the scraps may not have filled half the bin's volume even when fully spread out. This reduces the bin's space utilization. Solving this problem requires manual intervention, but excessive intervention significantly reduces the efficiency of the shredding process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a paper shredder that can automatically spread paper scraps out in the paper scrap bin, improve the space utilization of the paper scrap bin, reduce the frequency of manual intervention, and improve the efficiency of paper shredding.

[0004] The technical solution of this utility model is to provide a paper shredder, including a base, in which a paper scrap bin is disposed and movably connected; the base also includes a vibration module, which includes an electromagnetic vibrator, a magnet, and an elastic element. The elastic element is disposed within the base and is used to support the paper scrap bin and cause the paper scrap bin to return to its original position. One of the electromagnetic vibrator and the magnet is disposed within the base, and the other is connected to the paper scrap bin and is positioned opposite the one within the base. The electromagnetic vibrator is used to periodically and intermittently attract the magnet after being energized. The attraction between the electromagnetic vibrator and the magnet causes the paper scrap bin to move towards the base and causes the elastic element to undergo elastic deformation. When the electromagnetic vibrator and the magnet are not attracted, the elastic element rebounds and drives the paper scrap bin to return to its original position.

[0005] Compared with existing technologies, the paper shredder of this invention has the following advantages: A vibration module is installed inside the base. The electromagnetic vibrator and magnet in the vibration module are positioned opposite each other, with one side located inside the base and the other connected to the paper scrap bin. The electromagnetic vibrator contains an electromagnetic coil with an iron core inside. The current passing through the electromagnetic coil is a pulsed current rectified by a half-wave rectifier. During the positive half-wave, the current flows, the iron core is magnetized into an electromagnet, and it generates an attractive force on the magnet, drawing the paper scrap bin closer to the base and causing the spring... The elastic element undergoes elastic deformation; during the negative half-wave, no current flows, and the electromagnet's attraction to the magnet disappears. Due to the rebound effect of the elastic element, the paper scrap bin resets. Thus, the electromagnetic vibrator and the magnet experience periodic and intermittent attraction. Under the action of the electromagnetic vibrator, the paper scrap bin vibrates continuously, causing the paper scraps inside to vibrate continuously. This allows the paper scraps to automatically spread out evenly within the paper scrap bin, improving the space utilization of the paper scrap bin, reducing the frequency of manual intervention, and increasing the efficiency of paper shredding operations.

[0006] Preferably, the vibration module further includes a vibration table disposed on the elastic element, the paper scrap bin disposed on the vibration table, and one of the electromagnetic vibrator and the magnet disposed within the base, while the other is disposed on the vibration table and faces the one disposed within the base with a gap. The attraction between the electromagnetic vibrator and the magnet causes the vibration table, along with the paper scrap bin, to move towards the base. The rebound of the elastic element drives the vibration table, along with the paper scrap bin, to return to its original position. With this structure, the vibration table can be made of magnetic materials such as iron plates, allowing the magnet to be magnetically connected to the vibration table for easy assembly, while the paper scrap bin is generally made of plastic, thus eliminating the need for major modifications to the paper scrap bin.

[0007] Preferably, the vibrating table is provided with a limiting protrusion structure, and the paper scrap bin is provided with a limiting groove. The vibrating table and the paper scrap bin are connected by the limiting protrusion structure being embedded in the limiting groove. This structure facilitates the connection between the vibrating table and the paper scrap bin, allowing the vibrating table to move together with the paper scrap bin when subjected to force, thus preventing the vibrating table from separating from the paper scrap bin and causing the paper scrap bin to stop vibrating.

[0008] Preferably, the vibrating table and the waste bin are connected by a snap-fit ​​mechanism. This structure facilitates the connection between the vibrating table and the waste bin.

[0009] Preferably, one of the electromagnetic vibrator and the magnet is disposed on the inner bottom wall of the base, and the other is disposed at the bottom of the paper scrap bin, opposite to the one on the inner bottom wall of the base, with a gap between them. All of the aforementioned elastic elements are connected to or opposite the bottom of the paper scrap bin. With this structure, the vibration module, located below the paper scrap bin, causes the bin to vibrate up and down, which helps to evenly distribute the shredded paper inside.

[0010] Preferably, the vibration module is located on the side of the waste bin. One of the electromagnetic vibrator and the magnet is disposed on the inner side wall of the base, and the other is disposed on the side of the waste bin. Multiple elastic elements are connected to or opposite the side of the waste bin. With this structure, the vibration module, located on the side of the waste bin, causes the waste bin to vibrate left and right, which also helps to evenly distribute the shredded paper inside.

[0011] Preferably, it also includes a die head and a die body, with the die head mounted on the die body and positioned vertically opposite the opening of the waste bin. This structure facilitates direct flow of paper scraps into the waste bin. Attached Figure Description

[0019] Example 1:

[0020] like Figure 1 and Figure 2As shown, the paper shredder of this utility model includes a head 1 and a body 2. The head 1 is located on the top of the body 2 and adopts a paper shredder core of the prior art. The paper shredder of this utility model is located on the body 2 below the head 1. The paper shredder of this utility model includes a base 4 and a paper scrap bin 3 is provided on the base 4. The paper scrap bin 3 is movably connected to the base 4 vertically. The head 1 is located on the body 2 and is vertically opposite to the opening of the paper scrap bin 3.

[0021] A vibration module 5 is mounted on the base 4 and is located below the paper scrap bin 3. The vibration module 5 includes an electromagnetic vibrator 5-1, a vibration table 5-4, a magnet 5-2, and four springs 5-3. The vibration table 5-4 is provided with a limiting protrusion structure 5-5, and the bottom of the paper scrap bin 3 is provided with a limiting groove 3-1. The vibration table 5-4 and the paper scrap bin 3 are connected by the limiting protrusion structure 5-5, which is embedded upward into the limiting groove 3-1. The magnet 5-2 is connected below the vibration table 5-4. The vibration table 5-4 can be made of magnetic materials such as iron plates, and the magnet 5-2 can be magnetically connected to the vibration table 5-4. The electromagnetic vibrator 5-1 is located directly below the magnet 5-2 and is positioned opposite the magnet 5-2. The four springs 5-3 are located between the base 4 and the paper scrap bin 3 and are all connected to or opposite the bottom of the paper scrap bin 3. They are used to support the paper scrap bin 3 and allow the paper scrap bin 3 to return to its original position.

[0022] The electromagnetic vibrator 5-1 contains an electromagnetic coil with an iron core inside. The current flowing through the electromagnetic coil is a pulsed current rectified by a half-wave rectifier. During the positive half-wave, the current flows, the iron core is magnetized into an electromagnet, and it attracts magnet 5-2, along with the vibrating table 5-4 and the paper scrap bin 3, bringing them closer together. All four springs 5-3 are compressed. During the negative half-wave, no current flows, the electromagnet's attraction to magnet 5-2 disappears, and the springs 5-3 rebound, pushing the vibrating table 5-4, along with magnet 5-2 and paper scrap bin 3, back to their original positions. Thus, the electromagnetic vibrator 5-1 and magnet 5-2 experience periodic and intermittent attraction. Under the action of the electromagnetic vibrator 5-1, the paper scrap bin 3 vibrates continuously up and down, causing the paper scraps inside to vibrate continuously. This allows the paper scraps to automatically spread out evenly within the paper scrap bin, improving the space utilization of the paper scrap bin, reducing the frequency of manual intervention, and increasing the efficiency of the shredding process.

[0023] Example 2:

[0024] like Figure 3As shown, the vibration module 5 is located on the side of the paper scrap bin 3. The vibration table 5-4 is provided with a limiting protrusion structure 5-5. The side of the paper scrap bin 3 is provided with a limiting groove 3-1. The vibration table 5-4 and the paper scrap bin 3 are connected to the left by the limiting protrusion structure 5-5 embedded in the limiting groove 3-1. The magnet 5-2 is magnetically connected to the vibration table 5-4, that is, the magnet 5-2 is located on the side of the paper scrap bin 3. The electromagnetic vibrator 5-1 is located to the right of the magnet 5-2 and is opposite to the magnet 5-2 in the air. The spring 5-3 is provided between the base 4 and the paper scrap bin 3 and is connected to or opposite to the side of the paper scrap bin 3, and is used to reset the paper scrap bin 3.

[0025] In this embodiment, the electromagnetic vibrator 5-1 and the magnet 5-2 have a periodic and intermittent attraction. First, the magnet 5-2, together with the vibration table 5-4 and the paper scrap bin 3, is attracted to move to the right and close to the compression spring 5-3. Then, the spring 5-3 rebounds, pushing the vibration table 5-4, along with the magnet 5-2 and the paper scrap bin 3, back to their original positions. This process repeats continuously. Under the action of the electromagnetic vibrator 5-1, the paper scrap bin 3 vibrates continuously from side to side, and the paper scraps inside the paper scrap bin also vibrate continuously, so that the paper scraps can automatically spread out in the paper scrap bin and become evenly distributed.

[0026] In other embodiments, the vibration table 5-4 and the waste bin 3 can be snapped together.

[0027] In other embodiments, the vibration table 5-4 may not be provided, and the magnet 5-2 may be directly connected to the paper scrap bin 3. The magnet 5-2 may be embedded in the paper scrap bin 3 for fixation, or it may be pasted and fixed on the paper scrap bin 3.

[0028] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
