Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment, and in particular to a dual-chamber mixing aerator. Background Technology

[0002] An aerator is a device that creates a foaming effect on the water flow and saves water. An aerator allows the flowing water and air to mix thoroughly. The addition of air significantly increases the water's flushing power, thus effectively reducing water consumption and saving water. Generally, high-end faucets produce a gentle, comfortable mist-like water flow, filtering impurities and preventing splashing – this is the function of an aerator.

[0003] The outer diameter of the faucet is limited, which means that the size of the aerator is constrained by the size of the faucet. Therefore, how to improve the structure of the aerator as much as possible within the limited size so that it can incorporate more air and improve the user experience is the applicant's unremitting pursuit. Summary of the Invention

[0004] Therefore, it is necessary to provide a dual-chamber mixing bubbler with good air incorporation effect.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a dual-chamber mixing bubbler, comprising:

[0006] The outer cylinder has a first sealing plate at its top, and the first sealing plate has multiple jet holes, the diameter of which gradually decreases along the direction of water flow.

[0007] An inner cylinder is disposed within an outer cylinder. The top of the inner cylinder has a second sealing plate with multiple diffusion holes. The number of diffusion holes is equal to the number of jet holes. The diffusion holes are Venturi tube structures with their diameters gradually increasing along the direction of water flow. Each jet hole is equipped with one diffusion hole. The inlet of the diffusion hole is located directly below the outlet of the jet hole, and the outlet diameter of the jet hole is smaller than the inlet diameter of the diffusion hole.

[0008] There is a gap between the first sealing plate and the second sealing plate, which forms a first mixing chamber. The side wall of the outer cylinder has an air inlet, which is connected to the first mixing chamber.

[0009] The internal space of the inner cylinder forms a second mixing chamber.

[0010] Furthermore, the first sealing plate is provided with a first filter screen covering all the jet hole inlets.

[0011] Furthermore, a multi-layered second filter screen is provided at the outlet of the second mixing chamber.

[0012] Furthermore, along the direction of water flow, the mesh size of the second filter gradually increases in each layer.

[0013] Furthermore, the jet holes are arranged in the middle of the first sealing plate, and the top of the outer cylinder has an annular retaining ring surrounding all the jet holes.

[0014] Furthermore, the outer cylinder has a water passage inside its side wall, with the inlet of the water passage located at the edge of the first sealing plate and the outlet of the water passage located on the bottom end face of the outer cylinder.

[0015] Furthermore, the outer outer wall of the outer cylinder has a sealing ring at its top.

[0016] Furthermore, the bottom of the outer wall of the outer cylinder has external threads.

[0017] Furthermore, a retaining ring for fixing the second filter screen is screwed to the bottom of the outer cylinder.

[0018] Compared with the prior art, the present invention has the following advantages: the device achieves secondary integration of air into the water flow through the combination of jet holes and diffuser holes, thereby integrating a large number of fine and dense bubbles into the water flow to form sparkling water with a good user experience. The structure is simple.

Detailed Implementation

[0025] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0026] like Figure 1-4 As shown, a dual-chamber mixing aerator includes: an outer cylinder 1, an inner cylinder 2, a first filter screen 3, a second filter screen 4, and a retaining ring 5. The outer cylinder 1, the inner cylinder 2, and the retaining ring 5 are all integrally injection molded.

[0027] The top of the outer cylinder 1 has a first sealing plate 11, and the middle of the first sealing plate 11 has multiple jet holes 12. The diameter of the jet holes 12 gradually decreases along the direction of water flow. The operating principle of the jet holes 12 is small-diameter jet: water is ejected through a very small aperture. During this process, the water velocity increases sharply, forming a strong shearing effect with the surrounding air or gas, cutting the gas into tiny bubbles, some of which can reach the nanoscale.

[0028] The inner cylinder 2 is set inside the outer cylinder 1. The top of the inner cylinder 2 has a second sealing plate 21. The second sealing plate 21 has multiple diffusion holes 22. The number of diffusion holes 22 is equal to the number of jet holes. The diffusion holes 22 are Venturi tube structures, and their diameter gradually increases along the direction of water flow. The operating principle of the diffusion holes is the Venturi effect: using the Venturi tube structure, when water flows through the narrow part of the Venturi tube, the flow velocity increases and the pressure decreases, thereby drawing in gas. In the subsequent diffusion process, the gas mixes with water to form microbubbles. With proper design, nano-microbubbles can be generated.

[0029] Each jet orifice 12 is equipped with a diffuser orifice 22. The inlet of the diffuser orifice 22 is located directly below the outlet of the jet orifice 12, and the outlet diameter of the jet orifice 12 is smaller than the inlet diameter of the diffuser orifice 22.

[0030] A gap exists between the first sealing plate 11 and the second sealing plate 21, forming a first mixing chamber 13. The side wall of the outer cylinder 1 has an air inlet 14, which communicates with the first mixing chamber 13. The internal space of the inner cylinder 2 forms a second mixing chamber 23.

[0031] The first filter screen 3 covers all the inlets of the jet holes 12, and multiple layers of second filter screens 4 are provided at the outlet of the second mixing chamber 23. Along the direction of water flow, the mesh size of each layer of the first filter screen 3 gradually increases, and the mesh size of each layer of the second filter screen 4 gradually increases. The function of the first filter screen 3 is to cut the incoming water into fine water columns, which are more easily dispersed after entering the jet holes, promoting mixing with the gas; the function of the second filter screen 4 is to cut the bubbles into smaller bubbles after the sparkling water passes through these filters in sequence, thus obtaining a softer sparkling water.

[0032] In this device, after the water flows through the jet hole 12, the water velocity increases sharply. In the first mixing chamber 13, it forms a strong shearing action with the air, cutting the gas into tiny bubbles and merging them into the water to form primary bubble water. The primary bubble water then enters the diffuser hole 22. When the water flows through the narrow part of the venturi tube, the flow velocity increases and the pressure decreases, thereby drawing in gas. In the second mixing chamber, the gas and water mix to form tiny bubbles, which in turn form deep bubble water. The deep bubble water is then cut by the second filter screen 4, and the bubbles are cut into smaller diameter bubbles, resulting in softer bubble water.

[0033] In this embodiment, the jet hole 12 is arranged in the middle of the first sealing plate 11, and the top of the outer cylinder has an annular retaining ring 15 surrounding all the jet holes.

[0034] In this embodiment, the outer cylinder 1 has a water passage 16 inside its side wall. The inlet of the water passage 16 is located at the edge of the first sealing plate 11 (outside the annular retaining ring), and the outlet of the water passage 16 is located on the bottom end face of the outer cylinder 1. The presence of the water passage 16 gives this aerator two water outlet channels.

[0035] In this embodiment, the top of the outer wall of the outer cylinder 1 has a sealing ring 17; the bottom of the outer wall of the outer cylinder 1 has an external thread 18.

[0036] In this embodiment, a retaining ring 5 for fixing the second filter screen 4 is screwed to the bottom of the inner cylinder 1.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
