Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom equipment, and specifically refers to a porous aerator. Background Technology

[0002] A foamer is a device or apparatus used to generate foam in liquids. It is typically installed in faucets, shower heads, or beverage machines. Through special structures or technologies, it creates a large number of bubbles as water flows through it, thereby making the liquid smoother, producing richer foam, or improving the taste and cleaning effect. For example, a foamer is used in a coffee machine to create milk foam, while in car wash equipment, it enhances the cleaning power of detergents.

[0003] Existing aerators may generate splashing water during use, affecting the user experience. Utility Model Content

[0004] The main purpose of this utility model is to provide a porous aerator that solves the problems existing in the prior art, and produces a gentle water flow that is less prone to splashing.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A porous aerator includes a nut, a housing, a water distribution plate, and a cover. The nut has a first cavity, and the outer circumferential surface of the upper opening of the first cavity has an external thread. The housing fits into the lower opening of the first cavity, and its circumferential surface is uniformly provided with a plurality of air inlet grooves, the outer ends of which communicate with the lower opening of the first cavity. A second cavity is provided inside the housing, and the bottom of the second cavity is uniformly provided with a plurality of water outlet holes. The water distribution plate is disposed in the second cavity, and its two sides are uniformly provided with a plurality of water passages opposite to the water outlet holes. The cover fits into the upper opening of the first cavity, and its two sides are uniformly provided with a plurality of water inlet holes opposite to the water passages. A gap is reserved between the cover and the housing for air flow so that the air inlet grooves communicate with the water outlet holes. The cross-sectional area of ​​the water inlet holes is smaller than that of the water passages.

[0007] A limiting ring is provided at the lower opening of the first cavity, and a step is provided on the circumferential surface of the shell to abut against the limiting ring.

[0008] Preferably, the porous bubbler further includes a washer; the washer fits onto the surface of the cover.

[0009] The nut has a cross-section on its circumference.

[0010] One of the water inlets is located at the center of the cover, and the other water inlets are arranged at equal angular intervals around the central water inlet.

[0011] The air intake groove is recessed on the circumferential surface of the housing, and the circumferential surface of the water distribution plate is provided with a relief groove opposite to the air intake groove, and the inner side of the air intake groove is embedded in the relief groove.

[0012] The inner side of the cover is provided with a number of protrusions, which abut against the surface of the water distribution plate to form the gap.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] With several water inlets in the cover and several air inlets on the periphery of the shell, when water flows through the water inlets in the cover, the cross-sectional area of ​​the water passage increases sharply, creating a negative pressure at the outlet of the water inlet. This absorbs air entering from the side air inlets, causing the water and air to mix within the water passage, ultimately forming bubble water at the outlet. The water flow at the outlet is gentle and does not easily produce splashing water. At the same time, compared with other aerators in the prior art, the production of each component of this invention is easier, the yield rate is high, and the cost is controllable.

[0025] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0026] refer to Figure 1-4 As shown, this utility model discloses a porous aerator, including a nut 1, a shell 2, a water distribution plate 3, and a cover 4;

[0027] Nut 1 is provided with a first cavity 11, and the outer peripheral surface of the upper opening of the first cavity 11 is provided with an external thread 12 so that the aerator can be threadedly connected to the water supply pipe or water supply equipment.

[0028] The housing 2 fits into the lower opening of the first cavity 11, and its circumferential surface is evenly provided with a plurality of air inlet grooves 21. The outer end of the air inlet grooves 21 is connected to the lower opening of the first cavity 11. The housing 2 is provided with a second cavity 22, and the bottom of the second cavity 22 is evenly provided with a plurality of water outlet holes 23.

[0029] The water distribution plate 3 is installed inside the second cavity 22, and several water passages 31 are evenly arranged between its two sides, which are opposite to the water outlet 23.

[0030] The cover 4 fits into the upper opening of the first cavity 11, and several water inlet holes 41 are evenly arranged between its two sides, which are opposite to the water passage 31. A gap is reserved between the cover 4 and the shell 2 for air flow so that the air inlet groove 21 is connected to the water outlet hole 22. The cross-sectional area of ​​the water inlet hole 41 is smaller than that of the water passage 31.

[0031] Based on the above solutions, refer to Figure 3-4 As shown, through several water inlet holes 41 on the cover 4 and several air inlet grooves 21 on the periphery of the shell 2, when water flows through the water inlet holes 41 of the cover 4, the cross-sectional area of ​​the water passage 31 increases sharply, causing a negative pressure to be formed at the outlet end of the water inlet holes 41. This allows air entering from the side air inlet grooves 21 to be absorbed, causing water and air to mix in the water passage 31, ultimately forming bubble water at the outlet holes 23. Furthermore, the water flow in the outlet holes is gentle and does not easily produce splashing water. At the same time, compared with other aerators in the prior art, the production of each component of this invention is easier, the yield rate is high, and the cost is controllable.

[0032] The following are specific embodiments of the present invention.

[0033] A limiting ring 13 is provided at the lower opening of the first cavity 11, and a step 24 is provided on the circumferential surface of the housing 2 to abut against the limiting ring 13, which can prevent the housing 2 from falling out of the lower opening of the first cavity 11. Thus, when the nut 1 is connected to the water supply pipe or water supply equipment, the housing 2, the water distribution plate 3 and the cover 4 will not loosen.

[0034] Furthermore, this utility model also includes a washer 5; the washer 5 fits onto the surface of the cover 4 and serves as a buffer and seal after installation.

[0035] The circumferential surface of the nut 1 is provided with a cross section 14 so that the nut 1 can be turned by hand or with a tool.

[0036] One of the aforementioned water inlet holes 41 is located at the center of the cover body 4, and the remaining water inlet holes 41 are arranged at equal angles around the central water inlet hole 41. The water passage 31 and the water outlet hole 23 are arranged opposite to it.

[0037] The aforementioned air intake groove 21 is recessed on the circumferential surface of the housing 21. The circumferential surface of the water distribution plate 3 is provided with a relief groove 32 opposite to the air intake groove 21. The inner side of the air intake groove 21 is embedded in the relief groove 32 to achieve installation and prevent the water distribution plate 3 from rotating or shifting in the second cavity 22.

[0038] The inner side of the cover 4 is provided with a plurality of protrusions 42, which abut against the surface of the water distribution plate 3 to form the aforementioned gap.

[0039] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
