Problems solved by technology
[0003] When the current paper shredder is in use, paper jams often occur. Every time this happens, the paper shredder will be in an overload state, causing the temperature inside the paper shredder to be too high, and the circuit voltage suddenly increases. It is easy to cause damage to the circuit of the shredder, and cause serious damage to the driving equipment such as the motor, which may directly lead to the scrapping of the shredder

Embodiment Construction
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0020] see Figure 1-4 , a circuit protection device for a paper shredder, including a mounting base 1, the mounting base 1 plays the role of fixing each component, the material of the mounting base 1 is a hard insulating material and the middle part of the mounting base 1 is provided with a piezoresistor 2 and the installation holes of the thermistor 3 are homogeneously adapted. The resistance of the varistor 2 changes with the voltage. The greater the voltag...

A circuit protection device for a paper shredder, relating to the technical field of office equipment, comprising a mounting seat, and a piezoresistor is fixedly connected to the middle part on the left side of the mounting seat. The circuit protection device for paper shredders is used in conjunction with the piezoresistor and thermistor. In the initial state, the resistance of the thermistor is high, and the circuit where it is located is equivalent to a short circuit, and the resistance of the piezoresistor is small, so the voltage The circuit of the varistor is connected, and the conductive block is electrically connected with the electric ring to ensure the normal connection of the circuit of the paper shredder. When the paper shredder breaks down, the voltage rises, and the resistance of the varistor increases. The circuit of the varistor is disconnected, so that the paper shredder stops working, so as to avoid further damage to the paper shredder. As the temperature of the circuit rises, the resistance of the thermistor decreases. At this time, the circuit of the varistor is connected, so that the heating wire starts Heating, thereby achieving the effect of protecting the shredder, effectively ensuring the safety of the shredder, and prolonging the service life of the shredder.
Description
technical field [0001] The invention relates to the technical field of office equipment, in particular to a circuit protection device for a paper shredder. Background technique [0002] Paper shredders are office equipment often used in the office. Some unnecessary confidential documents are often put into the paper shredder for the purpose of destroying and shredding them, preventing important documents from being used by interested people and causing losses. [0003] When the current paper shredder is in use, paper jams often occur. Every time this happens, the paper shredder will be in an overload state, causing the temperature inside the paper shredder to be too high, and the circuit voltage suddenly increases. It is easy to cause damage to the circuit of the shredder, and cause serious damage to the driving equipment such as the motor, which may directly lead to the scrapping of the shredder. [0004] Therefore, we propose a circuit protection device for paper shredder...
