Provided are a beating structure and a foaming device. The beating structure comprises a base portion and multiple stirring rings (300) connected to the base portion and staggered in space. The beating structure also comprises at least one forming circle (310). The foaming circle (310) is disposed on at least one of the stirring rings (300), and is used for actively making bubbles formed during the spinning movement of the beating structure. The beating structure and the foaming device can well accelerate the foaming processing procedure.
