Through such an arrangement, the phenomenon of sewage seepage when the filtered food residues are piled up in one piece in the prior art is avoided.

[0036] By setting the inner bottom surface of the box body 1 as an inclined surface, the filtered sewage can flow out of the box body 1 more conveniently, which plays a guiding role for the filtered sewage to a certain extent. The residue discharge port 12 is set to be funnel-shaped, so that when discharging the filtered food residue, it is more convenient for the food residue to be discharged through the residue discharge port 12. By setting the anti-slip pad 201, the box body 1 is prevented from moving back and forth when the filter drum 5 rotates. By setting the observation window 26, it is convenient to check the specific situation in the box body 1.

[0037] By opening a rectangular groove 17 on the box body 1 and slidingly installing a brush 22 in the rectangular groove 17, clogging of the filter drum 5 during use is avoided, and the filter drum 5 is also cleaned. By setting the brush 22 as a detachable structure, when the brush 22 needs to be replaced, it is only necessary to press the mounting handle 24 to press the mounting handle 24 out of the mounting groove 21, and then rotate the mounting handle 24 and the connecting rod 23 to rotate the mounting handle 24 to a state parallel to the rectangular groove 17, and then pull the rotating handle 135 by hand to take the brush 22 out of the box body 1 and replace the brush 22. After the replacement is completed, the brush 22 is placed in the rectangular groove 17, and then one hand presses the mounting plate 20, and the other hand rotates the mounting handle 24 to rotate the mounting handle 24 into the mounting seat 18 until it is perpendicular to the rectangular groove 17, and then release the mounting plate 20, and fix the mounting handle 24 in the mounting groove 21 under the action of the spring 19.
