Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of office tools, and more particularly to a paper shredder. BACKGROUND

[0002] A paper shredder is an office equipment for cutting paper or other document materials into small pieces, and paper files enter the paper shredder through a paper feeding port. The paper shredder mainly destroys paper files through a set of rotating blades to achieve the purpose of protecting information security. In actual use, due to various reasons such as too much paper, uneven paper quality, old and disordered paper, etc., the paper is easily jammed in the paper feeding port, resulting in that the paper shredder cannot work normally. At present, some paper feeding paper shredders on the market do not have a paper cleaning structure, and some paper feeding paper shredders have a paper cleaning structure, but the structure is very complex, which is difficult to meet the needs of users to clean the jammed paper.

[0003] In view of the above problems, a utility model patent with the authorization announcement number CN218742345U discloses an automatic paper feeding paper shredder with a detachable paper cleaning structure, which comprises a matched upper cover and lower shell. The upper cover is formed with a manual paper feeding port and a paper cleaning window. The upper opening of the lower shell is installed with a blade group assembly and an automatic paper feeding mechanism. A paper cleaning protection plate for safely shielding the automatic paper feeding mechanism is positioned and placed in the paper cleaning window. Support protrusions for positioning and supporting the paper cleaning protection plate are formed on the two side surfaces of the paper cleaning window. Positioning tenon grooves are formed on the two side surfaces of the paper cleaning protection plate. Elastic clamping tenons for clamping into the positioning tenon grooves are formed on the two side surfaces of the paper cleaning window. The rear end of the paper cleaning protection plate is provided with a handle recess for conveniently taking out the paper cleaning protection plate from the paper cleaning window. In the technical solution, the paper cleaning protection plate can be taken out when paper jam occurs, the automatic paper feeding mechanism is completely exposed, and the purpose of cleaning the paper jam is achieved. However, the paper cleaning protection plate needs to be fixed and positioned through the elastic clamping tenon and the positioning tenon groove. The user needs to align and apply force in advance during use, which is tedious and laborious. The elastic clamping tenon may lose elasticity due to frequent disassembly and installation, resulting in that the fixing of the paper cleaning protection plate is not firm enough. Moreover, the elastic clamping tenon and the positioning tenon groove have higher precision requirements and higher production costs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a paper shredder. The first baffle is used to shield the paper feeding mechanism and the paper shredding mechanism. The detachable installation mode of magnetic attraction is adopted between the first baffle and the machine body, so that the first baffle can be more quickly and easily disassembled and assembled, and the operation is more convenient and reliable.

[0007] As an improvement, the body is provided with a magnetic induction switch matched with the second magnetic member, the first baffle is placed on the body by rotating to make the second magnetic member close to or away from the magnetic induction switch, and the magnetic induction switch controls the on-off of the body circuit by sensing the change of the magnetic field strength. In the technical solution, the magnetic induction switch is additionally arranged on the body, and the magnetic induction switch only makes the circuit of the body connected when the first baffle is placed on the body, and only makes the circuit of the body disconnected when the first baffle is separated from the body, thereby realizing intelligent control of the working state of the paper shredder. The magnetic induction switch is arranged to realize the control of the circuit of the body by sensing the approach or departure of the second magnetic member. When the first baffle is placed on the body, the second magnetic member approaches the magnetic induction switch, thereby triggering the circuit of the body, and the body can normally operate to complete the paper shredding work. When the first baffle is separated from the body, the second magnetic member departs from the magnetic induction switch along with the first baffle, thereby triggering the circuit of the body, and the body stops operating, so that the user can safely handle the paper jam and other maintenance problems. The magnetic induction switch can effectively avoid the misoperation caused by the incorrect closing of the baffle, reduce the risk of machine failure, improve the use safety, and the magnetic induction switch is matched with the second magnetic member in a magnetic induction mode, without the need of additionally arranging an induction element, thereby simplifying the structure design.

[0008] As an improvement, the magnetic induction switch is a Hall switch, the Hall switch controls the connection of the body circuit to make the body in the running state when the second magnetic member is connected with the Hall switch, and the Hall switch controls the disconnection of the body circuit to make the body in the stop state when the second magnetic member is separated from the Hall switch.

In the technical solution, the two sides of the first baffle are equipped with a plurality of second magnetic members, which allows the first baffle to be attracted to the plurality of first magnetic members on the machine body at both sides. The multi-point corresponding arrangement of the first magnetic member and the second magnetic member realizes multi-point adsorption connection between the first baffle and the machine body, improves the connection stability between the first baffle and the machine body, reduces the risk of overall connection failure caused by the failure of a single magnetic member, and ensures the stable adsorption and uniform stress of the baffle.

[0012] As an improvement, the first baffle is provided with a containing groove matched with the second magnetic member, and the second magnetic member is installed and limited in the containing groove. In the technical solution, the containing groove is arranged on the first baffle for matching and fixing the second magnetic member, and the second magnetic member is limited in the containing groove to ensure its fixed position and prevent displacement of the second magnetic member due to external force. The containing groove provides more stable structural support for the second magnetic member to prevent the second magnetic member from falling off or being lost during use, reducing maintenance costs and potential safety hazards.
