Problems solved by technology

Although this structure can prevent fingers from protruding in, it will cause the width of the paper inlet to be narrowed, and if children put their fingers on the tube, it may cause the fingers to be involved in the shredder because the tube slides forward. Can't play a good role in security protection

Embodiment Construction

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] Such as figure 1 , the safety type paper shredder shown in Fig. 2 includes a housing 1, a shredding blade group 2 arranged in the housing, a motor 3 for driving the blade group to work, and a control circuit for controlling the rotation of the motor, wherein the housing is in its There is a paper inlet 4 on the upper surface, and an independent cover plate 5 is arranged on the edge of the paper inlet. The cover plate is a conductive decorative material plate and has a narrow and long hole 51 corresponding to the paper inlet. , the pins are correspondingly connected to the jacks on the paper inlet, and a conductive sheet 6 is pasted on the edge of the paper inlet 14. The conductive sheet 6 is in contact with the conductive material on the inner surface of the cover plate, and the conductive sheet is connected to the first conductive memb...

Abstract

The safe shredder includes a casing with paper inlet, a paper shredding blade combination inside the casing, a motor to drive the blade combination and a motor control circuit. It features the conducting material set around the paper inlet and one conducting unit with the first end connected to the conducting material and the second end connected to the control circuit. In case the human body touches the conducting material, the generated inducing signal will stop the motor automatically through one inducing circuit to ensure the safety. In addition, the inducing control circuit possesses also automatic restoring function for restoring the normal operation of the shredder automatically after the abnormal state is eliminated.

Description

technical field [0001] The invention relates to a paper shredder, in particular to a safety type paper shredder which can prevent the operator's hand from entering the paper shredding port by mistake. Background technique [0002] In daily work and life, when using a paper shredder to crush documents and materials, the blade group of the paper shredder rotates quickly to cut the shredded objects. Generally, the existing paper shredders have an automatic induction paper feeding function, that is, when the paper is fed When paper is inserted into the paper opening, the control circuit of the paper shredder will control the motor to start and drive the blade group to rotate, and the inserted paper will be automatically introduced and shredded. After the shredding is completed, the control circuit of the paper shredder will control the motor stalled. However, if the user accidentally puts his hand into the paper inlet of the shredder, it will also cause the shredder to work aut...
