Bubble-containing liquid generator, bubble-containing liquid generator system, shower system, liquid supply device, liquid supply system, and treatment method

Abstract

The present invention provides a bubble-containing liquid generator and a bubble-containing liquid generator system that can improve the degree of freedom in adjusting the amount of dissolved gas in the liquid. [Solution] A bubble-containing liquid generator for generating a liquid containing bubbles, comprising an outer cylinder 11, a nozzle 12, and an injection port 136. The outer cylinder 11 is formed in a hollow shape. The nozzle 12 is inserted into the outer cylinder 11 so as to have a space 15 between it and the inner circumferential surface of the outer cylinder 11, and injects either liquid or gas toward the inner circumferential surface of the outer cylinder 11 through the space 15. The injection port 136 injects the other liquid or gas toward the liquid or gas being injected into the space 15.

Claims
