Description

Technical Field

[0001] The utility model relates to the technical field of paper shredders, in particular to a cooling wind wheel for paper shredders. Background Art

[0002] The shredder is composed of a set of rotating blades, a paper comb and a drive motor. The paper is fed in between the interlocking blades and cut into many small pieces of paper to achieve the purpose of confidentiality. The shredding method refers to the shape of the paper after it is processed by the shredder and cut by the shredder blade. After the drive motor runs for a long time, it will generate high temperature, and a cooling fan is needed to cool the motor inside the shredder.

[0003] The existing wind wheel and its peripheral components are often not user-friendly in design, which causes inconvenience to the daily maintenance and cleaning of the drive motor and wind wheel, making users face great troubles in the actual operation process, such as difficult disassembly and cleaning, which greatly increases the maintenance cost and time cost of the equipment. In addition, the working environment of the wind wheel is easily polluted and damaged by paper scraps, which may be sucked into the wind wheel, which will not only reduce the heat dissipation efficiency of the wind wheel, but also may cause the wind wheel to wear, blockage or even damage. Therefore, we proposed a cooling wind wheel for a shredder. Utility Model Content
