Embodiment Construction

[0020] The present invention will be further described in detail below with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.

[0021] refer to Figure 1-4 Shown:

[0022] A paper shredder with double protection function, comprising a case 1, a circuit board 2 is arranged inside the case 1, a first conductive plate 3 and a second conductive plate 4 are fixed on the upper end of the case 1, the first conductive plate 3, the second conductive plate The boards 4 are electrically connected to the circuit board 2, and the paper feed slot 5 is formed between the first conductive board 3 and the second conductive board 4. The paper feed slot 5 is provided with a shredding module 6, and the circuit board 2 is provided with a sensor circuit, when the user's hand touches the first conductive plate 3 and / or the second conductive plate 4, the induction circuit receives the weak current generated by the electric field of the hu...

Abstract

The invention provides a paper shredder with a double protection function, which comprises a case, a circuit board is arranged in the case, a first current-conducting plate and a second current-conducting plate are fixed at the upper end of the case, the first current-conducting plate and the second current-conducting plate are both electrically connected with the circuit board, a paper feeding groove is formed between the first current-conducting plate and the second current-conducting plate, a paper shredding module is arranged on the lower side of the paper feeding groove, a non-contact infrared thermometer is fixed to the case, and the non-contact infrared thermometer is located on one side of the paper feeding groove. According to the paper shredder provided by the invention, the situation of the position of the paper feeding groove can be monitored in real time through human body electric field induction and temperature measurement induction of the non-contact infrared thermometer, a power source of a motor is rapidly turned off with the assistance of a control system, potential safety hazards generated when the hand of a user accidentally stretches into the paper feeding groove are eliminated, and the paper shredder has the double protection function.

Description

technical field [0001] The invention relates to the technical field of paper shredders, in particular to a paper shredder with double protection functions. Background technique [0002] A paper shredder is an office equipment that can effectively prevent the leakage of document contents. In the prior art shredders, in order to speed up the shredding efficiency, the size of the paper inlet is usually increased so that more paper can be inserted into the paper inlet at one time. Due to the large diameter of the paper inlet, when the user does not operate properly, it is easy to cause damage to the hand, and there is a large potential safety hazard. Contents of the invention [0003] In view of the above problems, the present invention provides a paper shredder with double protection functions, which can monitor the position of the paper feeding slot in real time through the electric field induction of the human body and the temperature measurement induction of the non-conta...
