[0024] As an optimization solution of the utility model, two sets of cross blades driven by motors are used to crush the waste paper, thereby ensuring a thorough crushing effect.
[0025] See also Figure 1-Figure 4 As shown, the negative pressure guide structure includes a fan 8 installed on one side of the shredder box 2, the fan 8 is located on the front side of the waste paper drawer 6, and a plurality of air outlet mesh holes 19 are opened on the shredder box 2 between the waste paper drawer 6 and the fan 8, and a plurality of air outlet mesh holes 20 are opened on the waste paper drawer 6 between the waste paper drawer 6 and the fan 8; a symmetrical collecting plate 18 is fixed above the waste paper drawer 6.
[0026] As an optimization scheme of the utility model, a fan 8 is used to exhaust air outward to create negative pressure, so that the atmospheric pressure presses air into the waste paper outlet 5, and after passing through the waste paper drawer 6, it is discharged from the air outlet mesh hole 19, the air outlet mesh hole 20 and the fan 8, so that the airflow drives the paper scraps into the waste paper drawer 6. At the same time, the collecting plate 18 reduces the channel area entering the waste paper drawer 6, and the broken paper scraps entering are difficult to fly out.
[0027] See also Figure 1-Figure 4 As shown, the waste paper drawer 6 is an open square shape, and is movably installed at the bottom of the shredding box 2. When installed in the shredding box 2, the waste paper drawer 6 fits with the side wall of the shredding box 2. A handle 7 is provided in front of the shredding box 2.

[0030] As an optimization solution of the present invention, a photoelectric sensor switch 9 is used to conveniently detect whether there is paper entering, so that the double-layer cross-shredding structure and the fan 8 can be automatically started to perform the shredding work.
[0031] The use process of the utility model is as follows: the printing function is used by the printer body 1. When a printing error occurs and waste paper needs to be processed, the waste paper can be put into the waste paper port 5, and then the waste paper port 5 cuts off the light induction between the photoelectric sensor switch 9, so that the photoelectric sensor switch 9 sends a signal to start the double-layer cross-shredding structure. After being shredded by two cross-type blades, the paper scraps fall downward; at the same time, the fan 8 exhausts air outward to create negative pressure, so that the atmospheric pressure presses air into the waste paper port 5, and after passing through the waste paper drawer 6, it is discharged from the air outlet mesh hole 19, the air outlet mesh hole 20 and the fan 8, so that the airflow drives the paper scraps into the waste paper drawer 6. At the same time, the collecting plate 18 reduces the channel area for entering the waste paper drawer 6, and the entered paper scraps are difficult to fly out;
[0032] After a period of time, the user can take out the waste paper drawer 6 through the handle 7, clean out the paper scraps, and then put it back.
