Abstract

The inventors have studied a technology for utilizing a fine bubble generation mechanism for generating fine bubbles through water pressure feed and water pressure passage by an AC power supply pump having a pump output of 50 watts or more. However, the inventors have noticed that in such a technology there is a concern about the risk of electric leakage accompanying the use of an AC power supply. The inventors have also noticed that such a technology requires the wiring of a power supply cable, and the minimum size of a fine bubble generation device for obtaining a satisfactory water pressure amount is usually about half the size of a mandarin orange box, and thus it is often difficult to realize the miniaturization of the device.　Provided is a fine bubble generation device 1000, wherein a housing 1100 houses a pump 1300, a battery 1400, and a fine bubble generator 1500, and the housing 1100 is sealed so that water 1910 in a water tank 1800 does not enter the inside of the housing 1100.

Abstract

The present inventors have examined a technology for generating ultrafine bubbles defined as bubbles having a bubble diameter of less than 1 micrometer which is relatively small. However, in such a technology, the confirmation of the minute ultrafine bubbles is not only difficult with the naked eye, but also not easy even with an observation mechanism having a resolution of a microscope resolution level. The present inventors have noticed that there is a concern about the ambiguity that users cannot often confidently confirm the generation of significant bubble-containing purified water.　A fine bubble generation device 1000 has: an irradiator 1600 for irradiating water 1910 at a predetermined portion of a pipe inner portion 1230 with a light beam; and an imaging device 1700 for capturing an image of the water 1910 at the predetermined portion. The density of fine bubbles 1920 contained in the water 1910 is measured by analyzing the image of the water 1910 captured by the imaging device 1700.
