Title:
LIQUID SPRAYER
Document Type and Number:
WIPO Patent Application WO/2024/090146
Kind Code:
A1
Abstract:
Provided is a liquid sprayer with a simple structure, capable of spraying nanobubble-containing liquid. This liquid sprayer comprises: one or more spray nozzles for spraying liquid; a discharging device for discharging liquid; a first flow channel through which the liquid discharged from the discharging device flows towards one or more spray nozzles; and a microbubble generator provided in the middle of the first flow channel. In a tubular section in the microbubble generator, a small diameter section is provided, the inner diameter of the small diameter section is smaller than the inner diameter of a part of upstream of the small diameter section, the microbubble generator generates microbubbles in the liquid by means of cavitation generated when the liquid flowing through the tubular section passes the small diameter section from upstream of the small diameter section, and the cross-sectional area of the small diameter section is equal to or more than the sum of the opening areas of one or more spray nozzles.
