A micro-bubble generator is provided between an input end and an output end of a water outlet device. The micro-bubble generator includes a water inlet member and a water outlet member. A gas inlet gap is remained between the water inlet member and the water outlet member, with the gas inlet gap being communicated to external air, such that the external air is allowed to enter the micro-bubble generator for gas-liquid mixing and generate minute and dense bubbles.

A micro-bubble spray head and a washing apparatus. The micro-bubble spray head includes an integrated spray tube and a micro-bubble bubbler fixed on the outlet end of the integrated spray tube; a throttling passage portion is formed in the integrated spray tube; a plurality of throttling passages parallel to each other and having a uniform cross section are formed in the throttling passage portion along a water stream direction, so that a plurality of water streams can be formed in the plurality of throttling passages parallel to each other and having the uniform cross section and are sprayed out from the outlets of the plurality of throttling passages parallel to each other and having the uniform cross section in an expansion manner, so as to form negative pressure near the outlets; a plurality of air inlets serving as air inlet passages are further provided on the integrated spray tube.

A system for dispensing a plant-based milk includes a mixing chamber for emulsifying a plant-based paste and water, a plant-based paste storage connected to the mixing chamber via a first conduit, a water storage connected to the mixing chamber via a second conduit, and a cooling system. The system includes a pumping system for moving a prescribed amount of the plant-based paste into the mixing chamber upon receiving an input from a user via a user interface, a flow system for flowing water from the water storage to the mixing chamber, and a control system. The control system receives the input from the user, activates the pumping system and activates the flow system. Further, the control system activates the mixing chamber for emulsifying the plant-based paste and the water, and dispenses the emulsified plant-based mixture of the paste and the water.

A microbubble treatment agent cartridge assembly and washing equipment having the microbubble treatment agent cartridge assembly. The microbubble treatment agent cartridge assembly includes a housing and a treatment agent cartridge accommodated in the housing. The housing is provided with at least one water inlet pipe portion. The at least one water inlet pipe portion is provided internally with at least one stage of diameter-decreasing tapered portion and a microbubble former, and the pipe wall thereof is further provided with an air inlet hole. The air inlet hole is positioned between the at least one stage of diameter-decreasing tapered portion and the microbubble former, and communicates with an air inlet pipe disposed on the housing. The top of the most downstream stage of diameter-decreasing tapered portion is provided with a spray hole. The spray hole enables the water flow flowing through the at least one stage of diameter-decreasing tapered portion.

The present invention discloses a microbubble-producing water outlet assembly, which includes a housing, a water inflow component, a water through-flow disc and at least three layers of bubble mesh plates. The microbubble-producing water outlet assembly provided by the present invention has a simple structure, is easy to manufacture and easy to implement, has a low cost, and solves a problem that the water flow strength is too high but the content of microbubbles is too low in existing water outlet assemblies in the prior art.

The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.

A system and method for a multipurpose wine preparation device to facilitate pouring a wine from a wine bottle is provided. The body of the multipurpose wine preparation device has an inlet portion and an outlet portion. The inlet portion is configured to slidably engage into an opening of the wine bottle. The inlet portion has an inlet channel that extends therethrough. The outlet portion is defined by a first outlet at a first outward orientation; a second outlet at a second outward orientation, wherein the second outward orientation opposes the first outward orientation; a first outlet channel extending from a proximal end of the outlet portion to the first outlet; and a second outlet channel extending from the proximal end of the outlet portion to the second outlet, wherein the first outlet channel and the second outlet channel are in fluid communication with the inlet channel of the inlet portion of the body. During a wine pour, the wine pours out of the first outlet from the first outlet channel when the first outward orientation is downward, and wherein a continuous flow of air enters into the second outlet channel from the second outlet when the second outward orientation is upward during the wine pour of the wine.

A stirrer is provided that can more efficiently achieve shearing applied, by an action of an intermittent jet flow, to a fluid to be processed. The stirrer concentrically includes a rotor including a blade, a partition wall, and a screen, wherein: the screen includes a plurality of slits in a circumferential direction thereof and screen members located between the adjacent slit; by rotating at least the rotor of the two components, the fluid to be processed is discharged from the inside to the outside of the screen as the intermittent jet flow through the slit of the screen; the screen has a cylindrical shape having a circular cross section; an opening of the slit provided on the inner wall surface of the screen is used as an inflow opening; openings of the plurality of slits provided on the outer wall surface of the screen are used as outflow openings; and the width of the outflow openings in the circumferential direction is set to be smaller than the width of the inflow opening in the circumferential direction.
