Mechanically timed safety protecting device of shredder

Abstract

The invention relates to a mechanically timed safety protecting device of shredder, comprising a mechanically timing device and a safety protecting device; the mechanically timing device comprises a timer knob, a mechanic timer core and a touch component; the mechanic timer core is installed in the upper cover of the shredder; the timer knob is rotationally installed in the upper cover of the shredder and connected with the mechanic timer core; the touch component is installed on tail end of the a mechanic timer core; the safety protecting device is installed in the shredder and matched with the touch component; the safety protecting device is touched by the touch component, optimally, the mechanic timer core is the mechanic timer core of home appliances; the touch component is a cam; thesafety protecting device is a safety power-off switch, the paper inlet safety protecting device or the paper outlet safety protecting device. The invention is ingenious in conception, simple in structure, low in cost, practical in functions and convenient in application; the device is energy-saving regularly, safe and reliable; and the function of shredder is further improved.

Description

technical field [0001] The present invention relates to the technical field of paper shredders, more specifically, to the technical field of protection devices for paper shredders, in particular to a mechanical timing safety protection device for paper shredders. Background technique [0002] At present, among the applications of commercially available paper shredders, there is an energy-saving function, which uses software design of electronic circuits to automatically cut off the power of the machine during the built-in time when there is no shredding, so as to achieve the effect of energy saving. Because the energy-saving function is to use the user to cut off the power after a period of time when it is not in use, it also consumes more power, and the energy-saving effect is not good. Simultaneously because the user uses irregularity, the operation between different users can cause trouble, and does not know the working state that the machine is in and mistakenly thinks t...

Problems solved by technology

Because the energy-saving function is to use the user to cut off the power after a period of time when it is not in use, it also consumes more power, and the energy-saving effect is not good.

At the same time, because the user's use is not regular, the operation between different users will cause trouble, and they will mistakenly think that the machine is faulty because they don't know the working status of the machine.
