Description

Technical Field

[0001] The present invention relates to the technical field of shredders, and specifically provides a shredder for compressing and portably shredding waste paper. Background Art

[0002] A shredder is a commonly used device in offices. It is mainly used to shred some important discarded documents, so that if the documents are directly discarded, they may be collected by lawbreakers and cause losses.

[0003] The existing patent publication number is CN111250234B, which discloses a shredder including a box body, a paper feeding roller group and a shredding knife arranged in the box body. A laser component is provided at least on one side of the paper during transmission, and the laser component is located above the shredding knife; the laser component has a laser head, and the laser generated by the laser head irradiates the printed area of the paper. The shredder in the present invention adds a laser component on the basis of a traditional shredder. The laser generated by the laser component acts on the printed area of the paper to be shredded, heats the ink or toner forming information in the printed area to deform or evaporate the handwriting and other information, so as to realize the elimination or blurring of information, effectively preventing the risk of information leakage still existing in traditional shredders. Although it solves the problem of the risk of information leakage still existing in traditional shredders, its overall volume is relatively large.

[0004] The existing patent publication number is CN215586694U, which discloses a shredder with a compression structure, including a shredder body. A shredding component is arranged on the upper part of the shredder body, a debris storage cavity is arranged on the lower part of the shredder body, a control panel and a paper inlet are respectively arranged on the upper surface of the shredder body, a push-pull door body is hinged to the debris storage cavity, and a compression structure is arranged in the debris storage cavity. The compression structure includes a bag moving component and a rotating component. It can compress the collection bag and improve the space utilization rate of the collection bag. However, it only compresses the compression bag and has an overly large overall volume and is not portable.

[0005] The existing shredder has an integral box structure. Since the shredder is divided into a shredding part and a shredding collection part, the overall volume of the shredder is relatively large, occupying a large space, resulting in low portability of the shredder. Summary of the Invention
