A rotary stream drum

Abstract

This application provides a rotary stream drum, comprising: a housing, the housing being disc-shaped and hollow inside, with through holes at the center of two circular plates on the housing; a rotating assembly, the rotating assembly including a connecting shaft and a pair of rotating protrusions, the connecting shaft penetrating the housing and extending from the through holes at both ends, the pair of rotating protrusions being detachably connected to the two ends of the connecting shaft; a limiting tube sleeved on the connecting shaft, the limiting tube being placed inside the housing and its two ends abutting against the inner sides of the two circular plates of the housing; and a sound-generating assembly, the sound-generating assembly being disposed inside the housing, the sound-generating assembly including multiple contact baffles and several contact particles, the contact baffles being fixed inside the housing, and the contact particles striking the contact baffles to generate sound when flowing inside the housing. The stream drum provided by this application facilitates the rotation of the stream drum through the rotating protrusions, thereby causing the contact particles to undergo centrifugal motion inside the housing, thus contacting the contact baffles to generate sound.
