Shearing device and sparkling water generator

The utility model relates to a shearing device which comprises a shearing structure, and the shearing structure is of an annular body structure defined by at least one side plate. The two end faces ofthe annular body structure penetrate through each other and are used for circulation of water flow, and a plurality of protrusions are arranged on the inner annular wall of the annular body structure. A sparkling water generator comprises a pump shell and a pump cover, and a mixing space is formed by the pump shell and the pump cover. A mixing device is arranged in the mixing space, the mixing space is communicated with a water inlet pipeline and a water outlet pipeline, and the water outlet pipeline is further communicated with at least one shearing device. The shearing device is simple in structure and convenient to disassemble and assemble, large bubbles which are not dissolved in water flowing out of the water outlet pipeline can be repeatedly cut and further crushed, the size of thebubbles is greatly reduced
