[0043] In this embodiment, the functional particles supplied by the feeding system 2 can enter the quantitative groove 3101 through the adsorption effect of the negative pressure adsorption component. Each quantitative groove 3101 corresponds to a lower hopper 5 and also corresponds to a cavity particle filter rod.
