Description

TECHNICAL FIELD

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

[0002] The paper shredder is an office equipment which can cut paper or other paper documents into small pieces or granules, and can effectively shred some discarded confidential documents, save a lot of working time for users, and prevent others from obtaining the information recorded on the paper, thereby avoiding the leakage of technical or business secrets. The current paper shredder also needs to collect the cut paper scraps. A recycling barrel is arranged in the paper shredder, an upper opening of the recycling barrel is communicated with a paper scrap outlet of the paper shredder, and the paper scraps are recycled through the recycling barrel. Since there is only one paper scrap outlet of the paper shredder, the paper scraps are easily accumulated in the middle of the recycling barrel, so that most of the space of the paper recycling barrel cannot be effectively utilized, which not only affects the working efficiency of the paper shredder, but also increases the frequency of cleaning the recycling barrel for the user, thereby affecting the working efficiency and increasing the labor cost.

[0003] In view of the above problems, the utility model patent with the authorization announcement number CN202962592U discloses a paper ejecting mechanism of a paper shredder, which comprises a mounting side plate, a motor and a speed changer. The mounting side plate is mounted on the side wall of the upper end of the paper scrap barrel of the paper shredder. The motor is mounted on one side of the side wall of the mounting side plate. The output end of the motor is provided with the speed changer. The output shaft of the speed changer penetrates through the mounting side plate and is connected with the center of the rotating disc. A one-word through hole is formed in the middle of the rocking plate. A sliding column penetrates through the one-word through hole. The sliding column is connected with any point on the rotating disc except the center. The lower end of the side of the mounting side plate where the motor is mounted is provided with a paper ejecting rod in the transverse direction. The paper ejecting rod is connected with the lower end of the transmission short rod. The upper end of the transmission short rod is connected with one end of the transmission long rod. The other end of the transmission long rod is connected with the lower end of the rocking plate. In the technical scheme, the paper scraps in the paper scrap barrel are pushed by the paper ejecting mechanism, the space of the paper scrap barrel is effectively utilized, and the interval time for cleaning the paper scrap barrel is prolonged. However, the structure of the paper ejecting mechanism is relatively complex, and the paper ejecting mechanism pushes the paper through the paper ejecting rod. The rod-shaped paper ejecting rod penetrates through the paper scraps, and the paper ejecting efficiency is low. Therefore, there is still a need for a paper shredder which can effectively disperse the paper scraps and has a simple structure. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a paper shredder. The paper shredder is provided with a paper scrap dispersing plate between the paper scrap outlet and the paper scrap storage cavity.

An opening is arranged on the paper scrap dispersing plate. The paper scrap dispersing plate separates the first paper scrap outlet into a second paper scrap outlet through the opening. The design of multiple channels can disperse the paper scraps into the paper scrap storage cavity and improve the space utilization rate of the paper scrap storage cavity.

The accumulation amount of the paper residue in the conventional paper residue storage cavity only reaches 40% of the overall volume of the paper residue storage cavity. The paper residue distribution plate is arranged between the paper residue outlet and the paper residue storage cavity, so that the paper residue discharged from the paper residue outlet needs to pass through the paper residue distribution plate to enter the paper residue storage cavity.

The multiple first paper residue outlets can disperse and guide the paper residue to different areas of the paper residue storage cavity, so that the paper residue is dispersed and accumulated, the local accumulation of the paper residue in the paper residue storage cavity is avoided, and the space utilization of the paper residue storage cavity is improved. On the other hand, the opening is arranged on the paper residue distribution plate, the paper residue distribution plate can form a second paper residue outlet communicating with the paper residue storage cavity through the opening, and the first paper residue outlet is separated into the second paper residue outlet through the opening. Therefore, the paper residue on the paper residue distribution plate can be guided into the paper residue storage cavity through different first paper residue outlets and the second paper residue outlet.

In the technical solution, since the opening is arranged on the guide plate, the second chip outlet channel is actually closer to the middle part of the chip storage cavity than the first chip outlet channel, that is, the chip distribution plate guides the paper scraps to the area on the two sides of the chip storage cavity through the first chip outlet channel, and guides the paper scraps to the middle area of the chip storage cavity through the second chip outlet channel, so that the distribution of the paper scraps is more uniform, more areas of the chip storage cavity are covered, the paper scraps can be better dispersed, the space utilization of the chip storage cavity is greatly improved, and the chip distribution plate has simple structure and high dispersion efficiency.

In the technical solution, the chip outlet is separated into multiple outlets through the partition plate, and the first guide plate and the second guide plate are separated through the partition plate to form two first chip outlet channels which are distributed on opposite sides, so that the paper scraps can be more uniformly dispersed to the two sides of the chip storage cavity, and the distribution of the paper scraps in the chip storage cavity is more uniform through the cooperation of the guide plate and the partition plate.

[0010] As an improvement, the first guide plate and the second guide plate are both provided with openings; and the first guide plate, the second guide plate and the partition plate are integrally formed.

In the technical solution, the swingable chip distribution plate is arranged, when a large amount of paper scraps fall on the chip distribution plate, the paper scraps on the chip distribution plate can be shaken off into the chip storage cavity through slight swinging due to uneven force, so as to avoid that the paper scraps are accumulated on the chip distribution plate to block the chip outlet, thereby improving the efficiency of the paper scraps entering the chip storage cavity and improving the working efficiency of the whole machine.
