[0002] The shredder is used to shred documents and other items. The shredder uses the shredding motor to drive the shredding blade to rotate to realize the shredding function. During the shredding process, the temperature of the shredding motor will increase, especially in the When working at full load or overloaded, the temperature of the shredder motor rises very quickly, and the basic safety design of the shredder will install a temperature sensor on the shredder motor to force the shredder motor to stop working when the temperature of the shredder motor reaches the set value Or force the power off to avoid safety accidents caused by excessive temperature of the shredder motor. Even when shredding paper, the temperature of the shredder motor will gradually increase with the shredding time. After tens of minutes, the shredder motor will be forced to stop working, that is, the shredder cannot continuously shred paper for a long time, so it is necessary to improve it

The invention discloses a paper shredder capable of continuously shredding paper at high strength. The paper shredder comprises an active strong cooling mechanism, the active strong cooling mechanism comprises a refrigeration sealing cylinder and a semiconductor refrigeration assembly fixedly installed in an inner cavity of the refrigeration sealing cylinder, the inner cavity of the refrigeration sealing cylinder is partitioned by the semiconductor refrigeration assembly to form a heating chamber and a refrigeration chamber which are relatively sealed, a refrigeration air outlet is communicated with a motor air inlet, a motor air outlet 211 is communicated with a hot air inlet, and a hot air outlet is communicated with an exhaust window formed in a paper shredder head to form a hot air exhaust channel. The temperature of a paper shredding motor is reduced in an active refrigeration mode, the cooling speed of the temperature of the paper shredding motor is greatly increased, the continuous paper shredding time of the paper shredder is greatly prolonged, the continuous full-load paper shredding time of the paper shredder reaches 5 hours or longer, and the cruising capacity is higher.
