Description

Technical Field

[0001] This utility model belongs to the field of aerator technology, specifically referring to a faucet aerator. Background Technology

[0002] As a water-saving device at the point of use, the faucet aerator breaks the water flow into fine bubbles, improving user comfort while reducing splashing.

[0003] Traditional aerators often disperse water flow through a single-layer metal mesh, resulting in low bubble generation efficiency. High-pressure water flow can easily penetrate the filter, causing the water column to disperse, while low pressure can lead to intermittent water flow due to insufficient flow. In addition, the high-density aluminum or ceramic discs used in traditional aerators can improve the fineness of the bubbles, but they are prone to clogging due to impurities, requiring frequent disassembly and cleaning, which greatly reduces their service life. Utility Model Content

[0004] The purpose of this invention is to provide a faucet aerator with a simple structure, strong sealing structure, and the ability to achieve a stable microbubble water flow within a wide water pressure range.

[0005] The purpose of this utility model is achieved as follows:

[0006] A faucet aerator includes a housing, a rectifier is snapped onto the upper edge of the housing, a conical filter screen is snapped onto the top of the rectifier, and the conical filter screen has several water inlet holes, a wire mesh cavity is formed between the lower end of the rectifier and the housing, a wire mesh layer is snapped onto the inner wall of the wire mesh cavity, the rectifier has a rectifier flow hole with a top diameter larger than the bottom diameter, and several water outlet holes are provided at the bottom of the housing.

[0007] The present invention is further configured such that the mesh layer is composed of several parallel meshes, the mesh layer includes an upper mesh layer and a lower mesh layer, and the spacing between adjacent meshes in the upper mesh layer is 2-3 times the spacing between adjacent meshes in the lower mesh layer.

[0008] The present invention is further configured such that the wire mesh is a crisscrossing mesh structure.

[0009] The present invention is further configured such that the rectifying through hole includes a rectifying upper through hole and a rectifying lower through hole that are connected to each other. The rectifying upper through hole is frustum-shaped and the top diameter of the rectifying upper through hole is larger than its bottom diameter. The rectifying lower through hole is cylindrical and the diameter of the rectifying lower through hole is the same as the bottom diameter of the rectifying upper through hole.

[0010] The present invention is further configured such that the outer edge of the rectifier extends downward and is formed with a snap-fit ​​ring, and the inner sidewall of the housing near the top outer edge is formed with a snap-fit ​​ring groove adapted to the snap-fit ​​ring.

[0011] The present invention is further configured such that the snap ring is provided with a plurality of air intake notches, the number of which is four sets, and the notches are arranged in pairs facing each other.

[0012] The present invention is further configured such that an abutment post is provided at the bottom of the middle part of the conical filter screen, and the conical filter screen and the abutment post are integrally injection molded.

[0013] The present invention is further configured such that the water outlet holes are honeycomb-shaped.

[0014] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0015] 1. The various components of the faucet aerator provided by this utility model are installed by snap-fit, which makes the assembly simpler. The matching form of the rectifier and the shell ensures that there will be no problems such as water leakage or overfilling under high and low pressure. The multi-layered wire mesh disperses the water shape. The wire mesh with a higher density than traditional nano paper is less prone to clogging and the structure is more stable and reliable.

[0016] 2. The mesh layer in this utility model uses two different mesh layers with different adjacent mesh spacings, which makes it easier to produce denser bubble water.

[0017] 3. The rectifier upper through hole provided by this utility model can increase the water pressure, while the water pressure entering the rectifier lower through hole can be output stably.

[0018] 4. This utility model further provides an air inlet notch at the fitting gap between the rectifier and the housing to facilitate the entry of a small amount of air to form microbubble water.

[0019] 5. The water outlet holes in this utility model are honeycomb-shaped, which not only supports the bottom of the wire mesh, but also reduces the output pressure of the microbubble water. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3 :

[0029] A faucet aerator includes a housing 1, a rectifier 2 is snapped onto the upper edge of the housing 1, a conical filter screen 3 is snapped onto the top of the rectifier 2, and the conical filter screen 3 has several water inlet holes 30. A wire mesh cavity 10 is formed between the lower end of the rectifier 2 and the housing 1. A wire mesh layer 4 is snapped onto the inner wall of the wire mesh cavity 10. The rectifier 2 has a rectifier flow hole 20 with a top diameter larger than the bottom diameter. Several water outlet holes 11 are provided at the bottom of the housing 1.

[0030] During installation, the wire mesh layer is installed in the wire mesh cavity inside the housing 1 using a snap-fit ​​method, with the bottom wire mesh of the wire mesh layer 4 abutting against the upper end face of the water outlet hole 11. After installation, the housing 1 is snap-fitted and fixed to the rectifier 2, and then the conical filter screen 3 is snap-fitted and fixed above the rectifier 2. A slot structure is provided above the rectifier 2 to snap the edge of the conical filter screen 3 into the slot on the rectifier 2.

[0031] Water entering the aerator passes through the inlet hole 30, the straightening hole 20, the wire mesh layer 4, and the outlet hole in sequence, and the sprayed water forms microbubble water.

[0032] The conical filter screen 3 provides initial filtration; the rectifier flow hole 20 inside the rectifier regulates water pressure, preventing leakage and overfilling during high and low pressure water supply; and the wire mesh layer 4 foams the water.

[0033] Preferably, the mesh layer 4 is composed of several parallel meshes, and the mesh layer includes an upper mesh layer 40 and a lower mesh layer 41. The spacing between adjacent meshes in the upper mesh layer 40 is 2-3 times the spacing between adjacent meshes in the lower mesh layer 41.

[0034] In the above structure, the upper wire mesh layer 40 can foam the water for the first time, and the water entering the lower wire mesh layer 41 can foam it for the second time, so that the water from the water outlet hole can have a higher gas content.

[0035] Preferably, the wire mesh has an interwoven mesh structure. This interwoven mesh structure ensures that water flowing through each mesh is of the same size.

[0036] Preferably, the rectifying through-hole 20 includes a rectifying upper through-hole 21 and a rectifying lower through-hole 22 that are connected to each other. The rectifying upper through-hole 21 is frustum-shaped and the top diameter of the rectifying upper through-hole 21 is larger than its bottom diameter. The rectifying lower through-hole 22 is cylindrical and the diameter of the rectifying lower through-hole 22 is the same as the bottom diameter of the rectifying upper through-hole 21.

[0037] In the above structure, the design of the upper through hole 21 with a larger diameter at the top and a smaller diameter at the bottom can generate a water pressure difference, so that the water after passing through the upper through hole 21 can be pressurized to a certain extent, and the water after passing through the upper through hole 22 can be stabilized to a certain extent, so that the water pressure is more stable when entering the wire mesh layer 4.

[0038] Preferably, the outer edge of the rectifier 2 extends downward and is formed with a snap ring 23, and the inner sidewall of the housing 1 near the top outer edge is formed with a snap ring groove 12 that is adapted to the snap ring 23.

[0039] In the above structure, the rectifier 2 is fixed by inserting a snap ring 23 into the snap groove 12, and installation can be easily achieved by simple snapping.

[0040] Preferably, the snap ring 23 is provided with a plurality of air intake notches 24.

[0041] During the implementation of the above structure, although the snap ring 23 is snapped into the snap groove 12, the amount of air intake required to form microbubbles with water is not particularly high. A small amount of gas will still enter through the air intake gap 24 to ensure the generation of microbubbles.

[0042] Preferably, an abutment post 31 is provided at the center of the bottom of the conical filter screen 3 to achieve longitudinal support strength for the conical filter screen.

[0043] Preferably, the water outlet hole 11 is honeycomb-shaped.

[0044] In the above structure, the water outlet hole 11 is mainly used for microbubble water outlet. It does not participate in water foaming, and at the same time, it provides a certain support for the bottom of the wire mesh layer.

[0045] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
