Full paper detection device for paper shredder

Abstract

The invention relates to a full paper detection device for a paper shredder. The full paper detection device for the paper shredder comprises a receiving LED tube and an emitting LED tube which are arranged at a paper outlet of a lower cover of the paper shredder and are opposite in position. The receiving LED tube and the emitting LED tube are separately arranged on two parallel fixed plates, a full paper board is hinged to the paper outlet of the lower cover, a baffle plate between the receiving LED tube and the emitting LED tube is arranged upward on the top of the full paper board in a convex manner, and the receiving LED tube and the emitting LED tube are connected to an alarming circuit. Shredded paper of a garbage can in the paper shredder is continuously stacked and the height is more and more great, so that the shredded paper will push the full paper board to move, and the full paper board in the moving process will drive the baffle plate thereon to move to deviate from the original position; after the baffle plate moves to deviate from the original position, a signal emitted by the emitting LED tube can be received by the receiving LED tube; after the signal is communicated, the alarming circuit starts to alarm to remind full paper; by way of combining mechanical and electronic alarm, the full paper structure is simple and the cost is low, and moreover, parts are not damaged in the using process, so that the device is high in reliability.

Description

technical field [0001] The invention relates to the technical field of paper shredders, in particular to a paper full detection device for a paper shredder. Background technique [0002] A paper shredder is a machine used to shred and destroy paper. In order to achieve the confidentiality of discarded documents, the paper is divided into small pieces of paper. The divided fine fragments fall from the paper outlet of the shredder into the trash bin below. If the debris in the trash bin accumulates too much, it will affect the normal operation of the shredder, and the knife stick will be blocked from the paper outlet of the paper shredder. The normal shredding of shredded paper, and when the shredded paper is too full, it will inevitably cause the debris to spill and cause inconvenience for secondary cleaning. Therefore, the paper shredder needs a suitable full paper detection device to detect and remind the user Dispose of shredded paper in the trash can in a timely manner. ...

The divided fine fragments fall from the paper outlet of the shredder into the trash bin below. If the debris in the trash bin accumulates too much, it will affect the normal operation of the shredder, and the knife stick will be blocked from the paper outlet of the paper shredder. The normal shredding of shredded paper, and when the shredded paper is too full, it will inevitably cause the debris to spill and cause inconvenience for secondary cleaning. Therefore, the paper shredder needs a suitable full paper detection device to detect and remind the user Dispose of shredded paper in the trash can in time

[0003] The Chinese patent with the authorized announcement number CN201244505Y discloses a paper shredder full paper level warning device, which is used to detect the shredded paper height in the trash can through the detection device installed above the trash can and then uses the warning reminder device to alarm, but This kind of full paper detection and alarm device that relies entirely on electronic signals has poor reliability and high cost during use.

Another Chinese invention patent with the notification number CN103920580B is a mechanical full paper mechanism of a paper shredder, including a pressure plate and a touch switch. The touch part on the pressure plate moves when the paper is full and finally touches the touch switch to realize the purpose of full paper detection. , but this kind of mechanical full paper structure is not suitable for long-term use due to the frequent touch of the touch switch, which will cause severe wear and tear on the parts
