AI Technical Summary
Existing bath facilities struggle to generate sufficiently fine and uniform micro-nano bubbles, limiting the improvement of the bathing experience.
Using a pair of parallel dual pumps and a mixing tank, combined with a specially designed throttling aerator, the mixture of bath liquid and hydrogen is achieved through three-stage channels of narrowing, equalizing and expanding diameter, as well as a metal mesh, producing fine and uniform micro-nano bubbles.
Through repeated mixing, sufficiently fine and uniform micro-nano hydrogen bubbles are generated, enhancing the cleaning effect of the bath.
