The present invention relates to the field of bathroom accessories, in particular to a microbubble-producing water outlet assembly.
At present, the water outflow components of the existing showers, faucets and other products directly jet water, and utilize various complex function switching structures to form various water jetting patterns. As the requirements for health and water quality are increased gradually, the demand for the washing ability and the oxygen content in water is increased greatly. Therefore, researchers and developers have designed microbubble-producing faucets or showers. A microbubble-producing faucet or shower entrains air in the water outflow process so as to increase the oxygen content in the water flow. The bubbles produced by the entrained air can be used to clean vegetables, melons and fruits; the bubbles break after the water is sprayed to human body, thereby achieve a better cleaning and massage effect. However, existing microbubble-producing faucets or showers still have the following drawbacks: (1) with existing air entraining structures, the water flow reaches the water outlet before the air can be entrained into the water flow extensively owing to the high water flow speed; therefore, the content of entrained air in the water flow is low, the quantity of microbubbles is not enough, and the microbubbles are dispersed rapidly, can't achieve a satisfactory cleaning effect; (2) the fixing structure of existing microbubble-producing bubble mesh plates are too complex, resulting an over-sized water outflow component; in addition, the mesh plates may be displaced or deformed easily under the action of the water flow and have a short service life.
In summary, there is an urgent need for a water outlet assembly that solves the above problems to meet the market demand.
To overcome the above-mentioned drawbacks or problems in the prior art, the present invention provides a microbubble-producing water outlet assembly, which 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.
To attain the object described above, the present invention provides the following technical schemes:

wherein, water flows into the water through-flow holes from the water inflow holes, is mixed with the merged air, and is dispersed through the bubble mesh plates sequentially, and then flows out of the water outflow hole of the housing.
Furthermore, the plurality of water inflow holes in the water inflow component have a funnel-shaped longitudinal section respectively, and the funnel-shaped water inflow holes are arranged in a gradually tapered form in the water outflow direction.
Furthermore, the two air intake passages are arranged at an included angle with respect to each other and meet each other at the water inflow position of the corresponding water through-flow hole.

(a) The present invention provides a microbubble-producing water outlet assembly, which 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. In the present invention, the aperture difference between the water inflow holes and the water through-flow holes is utilized to create a strong negative pressure when the water is jetted into the water through-flow holes, so that the air in the air intake passages are sucked into the water through-flow holes. In that process, the air streams in the two air intake passages meet, collide or mix with each other, so that the air become mild before it enters the water flow, thereby the increase of water flow speed incurred by air pressurization is avoided effectively, while the air-water mixing duration is increased; thus, the air is entrained into the water flow extensively, and there is enough entrained air in the water flow when the water flows into the water mixing cavity; in addition, the water flow speed is decreased in the water mixing cavity, and big air bubbles in the water flow are fully broken into numerous microbubbles after the water flows through at least three layers of bubble mesh plates. Then, the microbubble-containing water flow can be used to wash vegetables, melons and fruits, or can be used for bath; thus, foreign matters can be removed effectively by means of microbubble breaking, and a better massage effect can be achieved as the microbubbles break on human body. The microbubble-producing water outlet assembly provided by the present invention has a simple overall structure, doesn't require any linkage or auxiliary structure, has a low cost, produces a large amount of microbubbles, and can meet the user' demand easily.
(b) The water inflow holes of the water inflow component in the present invention are funnel-shaped and gradually tapered, so that the water flows through the water inflow holes in a direction from a greater aperture to a smaller aperture, thereby the water flow speed is increased, and a better negative pressure effect is attained when the water is jetted into the water through-flow holes at the smaller-aperture water outflow position.
(c) The two air intake passages in the present invention are arranged at an included angle with respect to each other, so that the air collision is milder, and the air volume is more sufficient.
(d) The air distribution passages on the water through-flow disc in the present invention effectively attains an effect of sucking enough air into the internal water outlet, and the overall layout of the air distribution passages is reasonable, so that the air is sucked into the water flow mildly while sufficient air volume is maintained.
(e) The bubble mesh plates in the present invention are integrally formed, and the spacing between the bubble mesh plates is adjusted by stacking and nesting while the strength and stability of the bubble mesh plates are ensured.
(f) Bubble mesh plates with meshes in size of 100-200 mpi are used in the present invention to produce microbubbles in a better way and produce more microbubbles.
