Microbubble generating device

Abstract

The present invention provides a microbubble generating device, including: at least one unit body, the unit body including: at least one ring-shaped supporter; a plurality of vortex-generating protrusions spaced apart at a predetermined interval along an outer circumferential surface of the supporter; an inner module provided inside the supporter; a plurality of coupling grooves spaced apart at a predetermined interval along an edge of one side of the supporter; and a plurality of coupling protrusions formed to protrude at positions corresponding to the coupling grooves and spaced apart at a predetermined interval along an edge of another side of the supporter such that the coupling protrusions can be fitted and coupled to the coupling grooves when the plural supporters are stacked, wherein, when the plural unit bodies are stacked, the vortex-generating protrusions are formed as a plurality of intermittent helical projections spaced apart at a predetermined interval along an outer circumferential surfaces of the plural supporters.
