A hydrogen rich water generator includes a container, a hydrogen input, a dividing tube, a vibrator, and a cover. The container is used for containing water and comprises an opening and an inner wall. The hydrogen input is one-piece formed on the inner wall of the container and interconnects the inside and the outside of the container. The dividing tube is configured in the container and connected to the hydrogen input. The vibrator is used for vibrating the water. The cover is configured on the opening of the container wherein when the cover is removed, the water can be added or hydrogen rich water can be taken out. The vibrator of the creation can assist the hydrogen micro bubbles mixed with the water well to generate hydrogen rich water and humidified hydrogen.

Systems, devices, and methods for manufacturing nanobubbles are disclosed herein. In an embodiment, a nanobubble generator system includes a medium, wherein in the medium is a liquid medium or a semi-liquid medium. A device is immersed in the medium. The device includes a ceramic membrane having a first surface and an opposing second surface, and pores extending through the membrane from the first surface to the second surface, and a hydrophobic porous coating layer disposed on the first surface of the membrane. The system includes a gas source for providing a gas to the medium. In operation, the gas enters pores on the second surface of the membrane and exits the coating layer in the form of nanobubbles.

A method for producing an ultrafine-bubble-containing liquid includes: supplying a liquid containing at least one substance selected from a group stated below to a liquid supply region where an ejection orifice forming member in which an ejection orifice with a minute diameter is formed is disposed; and ejecting the liquid from the ejection orifice as a droplet by causing a pressure application unit in contact with the liquid to apply pressure to the liquid supplied to the liquid supply region. The group consists of a thermally denaturing material, inorganic salts, amino acids and their salts, carbohydrates/sugars and their salts, organic polymers and their salts, inorganic polymers and their salts, a dispersion, and an organic liquid.

A fine bubble generator for generating fine bubbles in a liquid without externally introducing gas. According to an embodiment, a liquid flows in a gap between a first helical part on an inner surface of an outer member having a tubular shape and a second helical part on an outer surface of an inner member in the outer member, so that cavitation occurs because of the decrease in pressure when the liquid flows out of the gap between the first helical part and the second helical part, and fine bubbles are generated in the liquid. In this process, the liquid flowing near the inner surface of the outer member swirls along the first helical part, and the liquid flowing near the outer surface of the inner member swirls along the second helical part, and cavitation is promoted by the swirl flows, and the amount of fine bubbles generated is increased.
