Wherein the second section 124 extends in a vertical direction, which is referred to herein as a general extending trend of the second section 124. It will be appreciated that the second section 124 may extend straight in a vertical direction, including obliquely, parallel with respect to the vertical direction, and that the second section 124 may also extend curved in the vertical direction. By extending the second section 124 in a vertical direction, the elements entering the second section 124 from the first section 123 can be moved under the force of gravity. The elements move more rapidly under the force of gravity without getting stuck in the discharge channel 12, thereby improving the discharge efficiency. This facilitates movement of the element from the inlet 121 to the outlet 122, achieving a discharge effect.
