AI Technical Summary
Technical Problem
The infrared photodetector in existing paper shredders is susceptible to electrostatic interference, resulting in a high false alarm rate and a poor user experience.
Method used
The detection module detects the weight of paper scraps. When the weight reaches a preset threshold, the switch module is triggered to control the infrared emitting module to turn on, generating infrared rays. The infrared receiving module receives the signal to determine whether the paper tube is full.
Benefits of technology
It effectively avoids electrostatic interference, reduces the possibility of false alarms from the shredder, and improves the user experience.

Abstract
The application discloses a paper shredder full paper detection device and a paper shredder. The paper shredder full paper detection device comprises a detection module, a switch module, an infrared emission module, an infrared receiving module and a control module. The detection module is used for generating a weight detection signal and triggering the switch module when the weight of paper scraps in the paper cylinder of the paper shredder reaches a preset threshold. The switch module is in communication connection with the detection module. The switch module is arranged at the bottom of the paper cylinder slot of the paper shredder. The switch module is used for controlling the infrared emission module to be turned on. The infrared receiving module and the infrared emission module are arranged on the same plane with the discharge port of the paper shredder. The infrared emission module is used for generating infrared rays. The infrared receiving module is connected with the control module. The infrared receiving module is used for generating a height detection signal. The control module is used for determining whether the paper cylinder of the paper shredder is full according to the height detection signal. The paper shredder full paper detection device of the embodiment of the application is beneficial to reducing the possibility of false positives of the paper shredder and improving user experience.
