Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom equipment, and specifically refers to a water-saving 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] Due to geographical limitations, water pressure varies in different regions. Existing aerators may cause excessive flow and water splashing due to excessive water pressure, resulting in water waste and a poor user experience. Utility Model Content

[0033] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0034] refer to Figure 1-5 As shown, this utility model discloses a water-saving aerator, including a nut 1, a shell 2, a water-spreading plate 3, a cover 4, a water-saving fixing seat 5, and a flow-limiting valve;

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The water-saving mounting base 5 is installed at the water inlet end of the cover 4, and a flow-limiting valve is installed inside it.

[0040] Through the above solution, this utility model directly installs a flow limiting valve inside the aerator. During the water inlet process, due to the action of the flow limiting valve, the flow rate of the aerator is determined by the flow rate of the installed flow limiting valve. Different flow limiting valves can be replaced according to different usage requirements to achieve different aerator flow rates.

[0041] The following are specific embodiments of the present invention.

[0042] The aforementioned flow-limiting valve includes a valve body 6 embedded in a water-saving mounting base 5, and a first sealing ring 7 disposed within the valve body 6. The valve body 6 is provided with an inlet ring groove 61, and a plurality of water passage holes 62 are provided at the bottom of the inlet ring groove 61. The first sealing ring 7 is fitted within the inlet ring groove 61 and does not completely block the water passage holes, and is compressed as the water pressure changes to change the effective cross-sectional area of ​​the water passage holes 62. Thus, when water enters the flow-limiting valve, the water pressure acts on the first sealing ring 7, and the first sealing ring 7 changes its compression amount as the water pressure changes, and the area of ​​the water passage holes 62 blocked also changes simultaneously, achieving the effect of limiting the flow rate.

[0043] Furthermore, the middle part of the water inlet ring groove 61 of the valve body 6 is a column for the first sealing ring 7 to be fitted, and the end face of the column is provided with a number of claws 63 for limiting the first sealing ring 7.

[0044] A second sealing ring 8 is provided between the inner wall of the water-saving fixing seat 5 and the nut 1.

[0045] The cross-sectional area of ​​the aforementioned water inlet hole 41 is smaller than that of the water passage 31. Through the several water inlet holes 41 of the cover body 4 and the several air inlet grooves 21 on the periphery of the shell 2, when water flows through the water inlet holes 41 of the cover body 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 hole 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 hole 23. Furthermore, the water flow in the outlet hole 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.

[0046] 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.

[0047] Furthermore, this utility model also includes a washer 9; the washer 9 fits onto the surface of the cover 4 and serves as a buffer and seal after installation.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.
