Distribution wheel and particulate matter releasing apparatus

Abstract

The present disclosure provides a distribution wheel and a particulate matter releasing apparatus. The particulate matter releasing apparatus includes a distribution wheel and a driving member. The distribution wheel includes a circumferential surface and defines a recess on the circumferential surface. The recess is configured for receiving particulate matter. An opening size of the recess is less than a bottom size of the recess. The driving member is configured to drive the distribution wheel to rotate. In the present disclosure, the opening size of the recess may be less than the bottom size of the recess, so as to avoid a situation that the particulate matter within the recess falls out of the opening of the recess prematurely and cannot reach a preset position when the distribution wheel is rotated to a position where the opening of the recess is downward or obliquely downward.

Dependencies are inferred from the claim text.
