The water inlet portion is fixedly arranged within the housing and has a water inlet and a water outlet extending therethrough. A flow channel substrate is fixedly arranged within the housing below the water inlet portion. Guide holes are formed circumferentially at intervals on the flow channel substrate and extend therethrough and are in fluid communication with the water outlet. A switch holder is rotatably positioned below the flow channel substrate. First and second pluralities of water flow holes are arranged circumferentially in the top surface of the switch holder and penetrate the top surface. Water outlet holes are formed on the bottom surface of an aerator holder and are in fluid communication with the first water flow holes. When the switch holder rotates to a first position where the first water flow holes are aligned with the guide holes, water flowing into the guide holes flows out of the water outlet holes through the first water flow holes.

A hose end spray head apparatus includes a spread head body and a hose coupling. The spray head body includes a mixing body and a spray outlet arm formed as a unitary construction. The spray outlet arm extends outwardly from the mixing body and includes a spray bore to discharge a mixed fluid. The spray bore communicates with atmosphere via a first radial sidewall bore and a first offset top surface bore. An axial bottom surface bore extends from the bottom surface to the spray bore and is draws product from a container so as to inject the product into the spray bore. A second radial sidewall bore is configured to communicate an open interior of the container with atmosphere. The hose coupling is secured to the mixing body and mounts to a fluid supply to form the mixed fluid which is discharged through the spray bore.

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 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.

A single-button water passage switching structure includes a water inlet assembly and a water outlet assembly. The water inlet assembly includes a water inlet body, an operating button, a first control assembly, and a second control assembly. The water inlet body has a first mounting chamber and a second mounting chamber. The first mounting chamber and the second mounting chamber each have a water inlet and two water outlets. The first control assembly is configured to realize a pause mode, a first spray mode or the switching of water passages of the second mounting chamber. The second control assembly is configured to realize the switching of water passages of a second spray mode or a third spray mode. The operating button is configured to link the first control assembly and the second control assembly.

A fan-shaped air suction spray nozzle automatically adjusting an air suction speed is provided in the present invention, which includes a spray nozzle body and a liquid channel, the spray nozzle body being provided with a liquid channel in communication with a nozzle hole, and further includes a pressure groove and an air intake channel, wherein an inlet section of the liquid channel is in communication with the pressure groove, and the air intake channel is in communication with the liquid channel after penetrating through the pressure groove; an air intake orifice plate is installed in the pressure groove through an elastic damping apparatus, and a change of the pressure at an inlet of the liquid channel causes the air intake orifice plate to move between the pressure groove and the air intake channel; the air intake orifice plate is provided with several through holes of the same or different sizes, which are configured to change the air intake volume in the liquid channel as the air intake orifice plate moves in the pressure groove.

A microbubble generation module includes a first net, a second net, and a buffering protection device. The first net is provided with a plurality of first through holes and at least one air intake through hole besides to the plurality of first through holes. The second net is arranged on the first net, and provided with a plurality of second through holes. A body accommodates the first net and the second net. The first through hole and the second through hole communicate with each other to form a fluid communicating channel. The air intake through hole is in communication with the fluid communicating channel. The air intake through hole promotes a generation of microbubbles at communicating parts of the plurality of first through holes and the plurality of second through holes when a liquid passes through the fluid communicating channels.

A faucet mounting assembly for a faucet includes a conical nut and a receiving clip. The conical nut is coupled to a nozzle. The receiving clip is coupled to an inner surface of the faucet and is configured to receive the conical nut within. The receiving clip includes a substantially annular base, one or more tabs and a slot. The one or more tabs including fixed ends fixed to the substantially annular base and free ends opposite the fixed ends and bounded by the slot. The one or more tabs are configured to flex radially between a non-flexed position and a flexed position. The one or more tabs flex into the flexed position when the conical nut is repositioned in and out of engagement with the receiving clip and return to the non-flexed position when the conical nut is seated within the receiving clip.

A sprayer able to adjust a flow of mixed solution and water is revealed. The sprayer can be used for cleaning objects, spraying mixed solution for agricultural purposes, and so on. The mixed solution is formed by liquid mixed with water while the liquid can be fertilizers, pesticides, detergents, and etc. The sprayer not only can spray out the mixed solution or water selectively, but also can adjust concentration and flow of the liquid.
