Problems solved by technology

For this reason, in order to reduce the noise generated during the operation of the shredder, some people tried to achieve the effect of shock absorption by installing plastic feet on the upper and lower corners of the shredder core, but the effect was not ideal after use.

Embodiment 1

[0016] Example 1: from figure 1 and figure 2 It can be seen that the micro-noise shredder is composed of a casing 1 and a shredder core 2 arranged inside it. The casing 1 is composed of a lower bottom cover 11 and an upper cover 12 buckled thereon, and the upper cover 12 and the lower bottom cover 11 are fixedly connected by screws 13 . There is a space between the upper cover 12 and the top surface of the inner shredder core 2 . The four corners of the inner bottom surface of the lower bottom cover 11 are provided with pits 14 for embedding the spring 3 and screw holes 15 for fixing the shredder core 2 (see image 3 ). The four corners of the bottom of the shredder core 2 are provided with bosses 21 corresponding to the pits 14 on the bottom surface of the lower bottom cover 11 and capable of being introduced into the ends of the spring 3 .

Embodiment 2

[0018] Example 2: From Figure 4 It can be seen that this is another environment-friendly silent paper shredder, its structure is basically the same as that of Embodiment 1, the only difference is that the spring 3 in Embodiment 1 is replaced by an elastic plastic pad 6, which can be embedded in the concave bottom of the bottom cover 11. The elastic plastic pad 6 of the pit 14 is a ring structure, and its end is provided with a stepped hole 61 that can cooperate with the boss 21 on the bottom surface of the shredder core. Its use effect is the same as spring 3.

Abstract

The invention relates to an environment protection mute paper shredder and comprises a housing which consists of a lower bottom cover and an upper cover and a paper shredder core which is arranged in the housing. The upper cover which is locked on the lower bottom cover is fixed by a screw. The paper shredder of the invention is characterized in that: the paper shredder core is positioned in the lower bottom cover and integrated with the lower bottom cover as a whole by a fastener; a cushion blocking is arranged between the bottom surface of the paper shredder core and the lower bottom cover; a clearance which can avoid the contact of an inner top surface of the upper cover and the paper shredder core is reserved between the both. The paper shredder of the invention has scientific design as well as simple and reasonable structure. Since the paper shredder core and the lower bottom cover are integrated as a whole in a no-clearance way, noises produced in the operation of the paper shredder core pass through the lower bottom cover to the ground and then spreads while the reserved clearance between the paper shredder core and the upper cover can prevent the upward propagation of the noise in the operation. The measures can ensure that the paper shredder core is completely separated from the upper cover and the lower bottom cover, thus obtaining an obvious effect of noise abatement and solving the problem of excessive noise during the operation of the paper shredder. The environment protection mute paper shredder is suitable for various places.

Description

technical field [0001] The invention relates to a paper shredder, in particular to an environment-friendly silent paper shredder capable of reducing noise during operation. Background technique [0002] At present, there are many types of shredders on the market, ranging from high-power shredders used in factories, which can shred large paper products or various plastic cards, to small shredders used by companies. For shredding confidential documents or waste paper. Shredders often improve their shredding effect by changing their shape, or by improving the shredding blades in the shredder, but people find that no matter how unique the design of the shredder or how reasonable the design of the shredder blade is , but cannot reduce or eliminate the noise produced by the shredder when it is running. The noise produced by the shredder is often the noise generated by the vibration between the shredder core (the part where the shredder blade is located) and the shredder casing d...
