[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the described embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains. The terms “first,” “second,” and similar terms used in the specification and claims of this patent application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a,” and similar terms, do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0027] like Figure 1 and Figure 2 As shown in the illustration, this application provides an example of a water-saving aerator, comprising a receiving cavity 10. The receiving cavity 10 contains a bundle of tubes formed by multiple Venturi tubes 131. Water enters from the inlet section 1311 of the Venturi tubes 131, passes through its throat section 1312, and finally flows out from the outlet section 1313. Due to the Venturi effect, a negative pressure is created at the throat, drawing in external air through the air inlet of the receiving cavity 10. A large amount of air enters the water flow through the Venturi tubes 131, forming bubbles. After the water flows out of the aerator, multiple high-speed water streams carry surrounding air into the aerator. This double mixing of air and water creates even more bubbles, making the water volume appear larger. Users will subconsciously turn down the water flow, thus achieving water conservation.

[0028] In this embodiment, the cavity 10 is provided with a plurality of venturi tubes 131 arranged in parallel along the longitudinal direction and integrally formed into a water inlet tube bundle 13, the upper surface of the water inlet tube bundle 13 being mesh-like; the upper end of the cavity 10 is provided with a connector 11 for connecting the water supply equipment and the cavity 10; the lower end of the cavity 10 is provided with a fixing member 12 for fixing the cavity 10.

[0029] Specifically, the receiving cavity 10 is a cylindrical structure with openings at both ends.

[0030] Specifically, the receiving cavity 10 is a cavity made of plastic or metal, such as stainless steel, which has a low manufacturing cost.

[0031] Specifically, the connecting piece 11 is a mounting thread arranged at the upper end outside the accommodating cavity 10. The external mounting thread is mainly used for cooperating with the internal thread of the faucet. By rotating, the bubbler can be stably installed at the water outlet of the faucet, and it is ensured that it will not be easily detached under the impact of water flow. In addition, the external thread design of part of the bubbler can also cooperate with different adapter accessories to adapt to various different specifications of faucets, thereby enhancing the universality of the bubbler.

[0032] Specifically, the fixing piece 12 is a hexagonal nut arranged at the lower end outside the accommodating cavity 10. The lower end hexagonal nut plays a role of fastening and sealing after the bubbler is installed to the faucet. When the bubbler is screwed into the faucet, the hexagonal nut at the lower end is tightened by using a wrench or the like, so as to further fix the bubbler and prevent it from loosening. At the same time, by tightening the hexagonal nut, the sealing element (such as a rubber gasket) between the bubbler and the faucet can better play a sealing role, so as to avoid the phenomenon of water leakage at the connection.

[0033] Specifically, the water inlet end of the accommodating cavity 10 can also be provided with a filter screen, and the filter screen is conical.

[0034] In this embodiment, the Venturi tubes 131 are longitudinally arranged along the accommodating cavity 10, and sequentially include a water inlet section 1311, a throat section 1312 and a water outlet section 1313 from top to bottom. The inner diameters of the water inlet section 1311 and the water outlet section 1313 are consistent, and the inner diameter of the throat section 1312 is smaller than that of the water inlet section 1311 and the water outlet section 1313. In turn, spaces are left between the plurality of Venturi tubes 131 to form air channels. The water outlet section 1313 of the Venturi tube 131 can serve as a flow guide channel. The diameter of the junction between the flow guide channel and the throat section 1312 is increased, and the upper and lower inner diameters of the flow guide channel are the same, which plays a role of guiding flow and preventing water flow from spreading out.

[0035] Specifically, the throat section 1312 is a cylindrical structure with wide ends and a narrow middle part.

[0036] Specifically, the throat section 1312 is provided with at least one first air inlet hole, and the throat section 1312 surrounding the water inlet pipe bundle 13 of the accommodating cavity 10 is uniformly provided with a plurality of second air inlet holes. The first air inlet hole and the second air inlet hole are in communication in the space of the air channel. External air enters the air channel through the second air inlet hole, and water flow enters from the water inlet section 1311 of the Venturi tube 131, flows out through the throat section 1312 and the water outlet section 1313. Because of the Venturi effect, a negative pressure is formed at the throat section 1312, and the air in the air channel is sucked in through the first air inlet hole, so that a large amount of air enters the water flow, thereby forming bubbles.

[0037] Specifically, each Venturi tube 131 is provided with 2-4 first air inlet holes, and these first air inlet holes are located on the circumference of the middle part of the Venturi tube 131 and are in communication with the second air inlet holes on the wall of the accommodating cavity 10.

[0038] In another aspect of the present application, a water faucet is disclosed, wherein the water faucet is installed with the water-saving starter as above.

[0039] In use, the water-saving bubbler of the present embodiment is screwed with the outer thread to the inner thread of the wall of the water faucet pipe by rotating the wrench, and then the hexagonal nut at the lower end is tightened by the wrench to further fix the bubbler and prevent it from loosening, thereby locking the bubbler on the water faucet. When the water is normally discharged, the water flow enters the water inlet section 1311 of the Venturi tube bundle, passes through the throat section 1312, and flows out from the water outlet section 1313. Due to the Venturi effect, negative pressure is formed at the throat, external air is sucked in through the air inlet hole, a large amount of air is mixed into the water flow, and bubbles are formed. After the water flow flows out of the bubbler, multiple high-speed water flows drive the surrounding air to mix in, and the twice air mixing into the water flow forms more bubbles, giving the visual effect of a large amount of water, and the user subconsciously turns off the water flow, thereby achieving the purpose of water saving.

[0040] In summary, the technical solution of the present application has the following beneficial effects:

[0041] 1. The water-saving bubbler of the present application has the advantages of simple structure, easy installation, prevention of water splashing, comfortable use, and water saving.

[0042] 2. The water-saving bubbler of the present application adopts multiple Venturi tubes to form a bundle, which can achieve the functions of guiding the water flow of the inner water outlet channel and simultaneously regulating the water flow of the water faucet outlet channel in an integrated structure, thereby improving the overall water outlet quality of the bubbler.

[0043] 3. The bubbler of the present application has the Venturi effect, negative pressure is formed at the throat, external air is sucked in through the air inlet hole, a large amount of air is mixed into the water flow, and bubbles are formed. After the water flow flows out of the bubbler, multiple high-speed water flows drive the surrounding air to mix in, and the twice air mixing into the water flow forms more bubbles, giving the visual effect of a large amount of water, and the user subconsciously turns off the water flow, thereby achieving the purpose of water saving.

[0044] The above is only a demonstrative embodiment of the present application, and is not used to limit the protection scope of the present application, which is determined by the appended claims.
