Description

Technical Field

[0001] This utility model relates to the field of water outlet device technology, specifically to a flow regulation structure and an aerator. Background Technology

[0002] In current water outlet device designs, to address the need for stable water flow under varying water pressure conditions, most solutions rely on integrated flow regulation structures. These structures often utilize the direct action of water pressure on elastic components, controlling flow through the deformation of these components, and integrating filtration within the elastic components, including a flow passage. However, while this design enhances system overall performance, its performance under low water pressure conditions is limited. When water pressure decreases, the water flow through the flow passage significantly reduces, weakening the impact of the water flow on the elastic component and limiting its deformation. Due to the reduced deformation, the elastic component's effectiveness in regulating flow is greatly diminished, making it almost impossible to effectively achieve the intended flow-limiting function. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned defects or problems in the prior art and to provide a flow regulating structure and an aerator that can ensure good deformation of the elastic element even under low water pressure conditions.

[0005] The first technical solution relates to a flow regulation structure, comprising: an elastic element, which includes a water-passing portion located in the middle and a pressure-bearing portion surrounding the water-passing portion, the water-passing portion protruding from the pressure-bearing portion; and a water-passing component, which accommodates the elastic element and cooperates with the elastic element to form a water-passing cavity, the water-passing cavity having water-passing holes around its periphery, and a water-spreading platform corresponding to the water-passing portion in the middle of the water-passing cavity; the pressure-bearing portion is adapted to deform under water pressure, so that the gap between the portion where the pressure-bearing portion and the water-passing portion meet and the outer edge of the top of the water-spreading platform changes, thereby adjusting the water flow area.

[0008] The fourth technical solution is based on the third technical solution, wherein when the pressure-bearing part is impacted by water flow, it elastically deforms in the direction toward the water passage until it abuts the first protrusion.

[0009] The fifth technical solution is based on the third technical solution, wherein the pressure-bearing part, under the action of water pressure, elastically deforms and abuts against the first protrusion in the direction toward the water passage cavity.

[0014] The tenth technical solution is based on the ninth technical solution, wherein the extension section from the guide surface to the water outlet is horizontally arranged.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution and related embodiments, the flow regulation structure achieves water flow regulation through the synergistic effect of the elastic element and the water-passing element. Specifically, the water-passing part not only serves as a barrier for the initial filtration of water flow but also cooperates with the water-spreading platform within the water-passing part to form the main channel path for water flow. The pressure-bearing part has elastic properties; when water flows through, the applied water pressure directly acts on the pressure-bearing part, causing it to undergo corresponding elastic deformation according to the water pressure intensity, affecting the gap between the water-passing part and the top of the water-spreading platform, thereby regulating the water flow area. As the water pressure increases, the pressure-bearing part gradually concaves inward towards the water-passing cavity, reducing the area of ​​the water-passing channel, limiting the speed and total volume of water flow, and ensuring the stability and controllability of water flow under high pressure. Under low water pressure conditions, due to the limitation of the water-passing part's area, water flow will form a natural accumulation and pressure-holding effect on its surface when passing through, increasing the pressure of the water flow on the pressure-bearing part, causing it to deform to adjust the water-passing channel, ensuring that the stability and flow rate of water flow can be reliably guaranteed even under low water pressure conditions.

[0017] In the second technical solution and related embodiments, the water passage area of ​​the water passage part is larger than that of the water distribution platform. Even under high water pressure, a certain gap is maintained between the water passage part and the outer edge of the top of the water distribution platform to ensure the continuous flow of water.

[0018] In the third technical solution and related embodiments, several first protrusions are evenly distributed around the circumference of the water distribution platform. When water flows through the water passage towards the water passage hole, it will first encounter the first protrusion. Due to the presence of the first protrusion, the water flow that may have been relatively concentrated is effectively dispersed. This dispersed water flow will flow to each water passage hole in a more uniform and dispersed manner along the first gap formed between two adjacent first protrusions.

[0019] In the fourth technical solution and related embodiments, the first protrusion is a conical protrusion, whose conical surface gradually expands along the water flow direction, so that the water flow can be subjected to a more uniform and gradually enhanced dispersion force when impacting the conical surface. As the water flows towards the wider end of the conical surface, the water flow is gradually dispersed into smaller and more uniform water flow bundles.

[0020] In the fifth technical solution and related embodiments, a first protrusion is introduced as a limiting device for the elastic deformation of the pressure-bearing part. Under high water pressure, the impact force of the water flow on the pressure-bearing part increases, potentially causing excessive elastic deformation and affecting the stability and reliability of flow regulation. However, through the limiting effect of the first protrusion, the deformation of the pressure-bearing part is effectively controlled within a reasonable range. Once the pressure-bearing part contacts the first protrusion, further deformation is hindered, thus preventing structural damage or functional failure that may result from excessive deformation.

[0021] In the sixth technical solution and related embodiments, the second protrusions, positioned near the water passage holes, are evenly distributed circumferentially and face the first gap or the first protrusions, further dispersing the water flow that has been initially dispersed by the first gap. After passing through the first gap, the water flow encounters the second protrusions, which are evenly distributed circumferentially. These protrusions further divide the water flow into smaller streams. As the water flow advances, these water streams, dispersed by the second protrusions, then flow out through the second gaps formed between adjacent second protrusions, eventually converging into each water passage hole.

[0022] In the seventh technical solution and related embodiments, water passage holes are provided in the water passage section to effectively filter out impurities and particulate matter in the water flow, improving the water quality after passing through the flow regulation structure. The water passage section can be configured with single or multiple water passage holes to adapt to different water quality and flow rate treatment requirements. The water passage holes are evenly distributed in the water passage section to ensure uniform filtration of the water flow in all directions, avoiding the problem of excessive local filtration burden. Simultaneously, because the water passage section protrudes from the pressure-bearing part, gravity allows impurities generated during the filtration process to be naturally guided to the surrounding area, effectively preventing the accumulation and blockage of impurities in the water passage holes.

[0023] In the eighth technical solution and related embodiments, the aerator employing this flow regulation structure achieves the dual functions of gas-liquid mixing and flow regulation, adapting to environments with varying water pressures. The aerator body and the flow regulation structure work together to form a gas-liquid mixing chamber. When water flows from the narrow water passage around the flow regulation structure into the relatively spacious gas-liquid mixing chamber, the water flow velocity increases, creating a negative pressure effect within the mixing chamber. This negative pressure state creates a pressure difference with the outside environment, attracting outside air to rapidly enter the mixing chamber through the venting groove, where it mixes thoroughly with the water flow dispersed by the flow regulation structure, forming bubble water.

[0024] In the ninth technical solution and related embodiments, the periphery of the aerator body is configured as an arc-shaped guide surface. Since the water passage is located around the periphery of the water passage cavity, the water exiting the water passage mixes with the air entering from the ventilation groove on the side wall of the aerator body to form a gas-liquid mixture that impacts the arc-shaped guide surface. The arc of the guide surface effectively disperses the impact force of the water flow, allowing the water to flow more smoothly along the guide surface and reducing the risk of leakage. The arc design causes the gas-liquid mixture to gather towards the center on the guide surface. During this process, the contact area between the water flow and the air increases, resulting in more thorough mixing and improved air mixing effect. The evenly distributed water droplets avoid hollow areas. Simultaneously, at least some of the gas-liquid mixture can rebound upwards in a direction away from the guide surface, promoting the tumbling and re-rectification of the water flow within the aerator body's internal cavity, making the water output more uniform and improving the fineness and stability of the bubbles.

[0025] In the tenth technical solution and related embodiments, the extension section from the guide surface to the water outlet is horizontally set to form a stable water outlet channel. During the gas-liquid mixing process, even if the internal water flow is disturbed by the gas mixing force, this horizontal extension section can effectively prevent the gas-liquid mixed water from flowing backward along the guide surface, especially preventing it from flowing back to the outside through the venting groove, thus reducing the risk of leakage.

[0044] Example 1

[0045] See Figures 4 to 7 A flow regulation structure includes a water-passing component 2 and an elastic component 1.

[0046] The elastic element 1 includes a pressure-bearing part 11 and a water-passing part 10. The water-passing part 10 is located in the center, and the pressure-bearing part 11 surrounds the water-passing part 10, protruding from the pressure-bearing part 11. The flow regulation structure uses water pressure to directly act on the elastic element 1, regulating the flow rate through the deformation of the elastic element 1, and integrating filtration function into the elastic element 1. Specifically, the elastic element 1 is a single thin sheet, and the water-passing part 10 in the middle of the thin sheet is a dispersed filtration structure. The pressure-bearing part 11 is an elastic structure that deforms elastically under the impact of water flow. The elastic structure of the elastic element 1 is simple, and the deformation of the pressure-bearing part 11 is controllable. The use of a single thin sheet makes the elastic element more sensitive and facilitates the adjustment of the outlet water pressure / flow rate.

[0047] The water passage section 10 is provided with at least one water passage hole 12. In this embodiment, the number of water passage holes (12) is greater than one. Several water passage holes 12 are evenly distributed in the water passage section 10. Providing water passage holes 12 in the water passage section 10 can effectively filter out impurities and particulate matter in the water flow, improving the water quality after passing through the flow regulation structure. Figure 5 and Figure 6 As shown, the water passage section 10 is configured with multiple porous water passages 12, and the number of water passages 12 is greater than one. Several water passages 12 are evenly distributed in the water passage section 10, which protrudes vertically from the pressure-bearing section 11, forming an umbrella-shaped structure. When the water passages 12 have a porous structure, their even distribution ensures uniform filtration of water flow in all directions, avoiding excessive local filtration burden. Simultaneously, because the water passage section 10 protrudes from the pressure-bearing section 11, gravity allows impurities generated during filtration to naturally flow to the surrounding area, effectively preventing accumulation and blockage of impurities in the water passages 12.

[0048] Water-passing component 2, such as Figure 4 As shown, it is used to accommodate the elastic element 1 and cooperate with the elastic element 1 to form a water passage cavity 20. Specifically, the elastic element 1 is placed above the water passage component 2 and snap-fitted with the water passage component 2, and is tightly fitted with the water passage component 2 to form the water passage cavity 20. The bottom wall of the water passage component 2 is provided with a water distribution platform 22, a first boss 23 and a second boss 24.

[0049] like Figure 4 As shown, the water passage chamber 20 is provided with water passage holes 21 surrounding the water distribution platform. There are several water passage holes 21, and water through holes 12 communicate with them. These water passage holes 21 allow water to flow to the aerator. The water distribution platform 22, as shown... Figure 4As shown, it is located in the middle of the water passage cavity 20, corresponding to the water passage part 10, and cooperates with the water passage part 10 to form a water passage channel. The pressure-bearing part 11 is adapted to deform under water pressure, so that the gap between the interface between the pressure-bearing part 11 and the water passage part 10 and the top of the water distribution platform 22 changes, thereby adjusting the water flow area. The area of ​​the outer edge of the water passage part 10 is larger than the area of ​​the outer edge of the top of the water distribution platform 22. Specifically, the water distribution platform 22 can be, but is not limited to, a cylindrical or polygonal boss, and the water passage part 10 is located directly above the water distribution platform 22. The water passage area of ​​the water passage part 10 is larger than the area of ​​the outer edge of the top of the water distribution platform 22, so that even under high water pressure, a certain gap is maintained between the water passage part 10 and the outer edge of the top of the water distribution platform 22, ensuring the continuous flow of water.

[0050] The first protrusion 23 is located in the center of the water passage cavity 20 and is evenly distributed around the water distribution platform 22. A first gap 25 is formed between adjacent first protrusions 23, communicating with the water passage hole 21. Specifically, the first protrusions 23 are located on the periphery of the water distribution platform 22 and are evenly distributed. The first protrusion 23 is a conical protrusion, whose conical surface gradually widens along the water flow direction, and its narrow conical apex faces the water distribution platform 22. When water flows through the water passage to the water passage hole 21, it will first encounter the several first protrusions 23 evenly distributed around the water distribution platform 22. Due to the presence of the first protrusions 23, the water flow that may have been relatively concentrated is effectively dispersed. This dispersed water flow will flow to each water passage hole 21 in a more uniform and dispersed manner along the first gap 25 formed between adjacent first protrusions 23. The first protrusion 23 is a conical protrusion, whose conical surface gradually expands along the direction of water flow, so that the water flow can be subjected to a more uniform and gradually increasing dispersion force when impacting the conical surface. As the water flows towards the wider end of the conical surface, the water flow is gradually dispersed into smaller and more uniform water flow streams.

[0051] like Figure 6 and Figure 7 As shown, under water pressure, the pressure-bearing part 11 elastically deforms in the direction toward the water passage cavity 20 until it abuts against the first protrusion 23. In this embodiment, the first protrusion 23 is introduced as a limiting device for the elastic deformation of the pressure-bearing part 11. Under high water pressure, the impact force of the water flow on the pressure-bearing part 11 increases, which may cause the pressure-bearing part 11 to produce excessive elastic deformation, thereby affecting the stability and reliability of flow regulation. However, through the limiting effect of the first protrusion 23, the deformation of the pressure-bearing part 11 is effectively controlled within a reasonable range. Once the pressure-bearing part 11 contacts the first protrusion 23, its further deformation will be hindered, preventing structural damage or functional failure that may be caused by excessive deformation.

[0052] The second protrusion 24, as shown Figure 4As shown, the second protrusion 24 is located around the periphery of the water passage cavity 20 near the water passage hole 21. It is evenly distributed around the water passage hole 21, located outside the first protrusion 23, and facing the first gap 25 or the first protrusion 23. A second gap 26 communicating with the water passage hole 21 is formed between adjacent second protrusions 24. Specifically, the second protrusion 24 is located on the outer ring of the first protrusion 23 and close to the water passage hole 21. The second protrusion 24 is square in shape. A water passage slit is formed between the second protrusion 24 and the ribs distributed around the periphery. A second protrusion 24 is spaced apart from the ribs to separate the water passage slits and form the water passage hole 21. The second protrusion 24 further disperses the water flow that has been initially dispersed by the first gap 25. After the water flow passes through the first gap 25, it encounters the second protrusions 24 evenly distributed around the periphery. These protrusions further divide the water flow into smaller streams. As the water flows forward, the water that has been dispersed by the second protrusion 24 will then flow out from the second gap 26 formed between two adjacent second protrusions 24, and eventually flow into each water passage 21.

[0053] In this embodiment, the flow regulation structure achieves water flow regulation through the synergistic action of the elastic element 1 and the water-passing element 2. Specifically, the water-passing part 10 not only serves as a barrier for the initial filtration of water flow but also cooperates with the water-spreading platform 22 within the water-passing element 2 to form the main channel path for water flow. The pressure-bearing part 11 has elastic properties; when water flows through, the applied water pressure directly acts on the pressure-bearing part 11, causing it to undergo corresponding elastic deformation according to the water pressure intensity. This affects the size of the gap between the water-passing part 10 and the top outer edge of the water-spreading platform 22, thereby regulating the water flow area. As the water pressure increases, the pressure-bearing part 11 gradually concaves inward toward the water-passing cavity 20, reducing the area of ​​the water-passing channel, limiting the speed and total volume of water flow, and ensuring the stability and controllability of water flow under high pressure. Under low water pressure conditions, due to the limited area of ​​the water passage 10, the water flow will form a natural accumulation and pressure-holding effect on its surface when it passes through, which will increase the pressure of the water flow on the pressure-bearing part 11, causing it to deform to adjust the water passage, and ensuring that the stability and flow rate of the water flow can be reliably guaranteed under low water pressure conditions.

[0054] Example 2

[0055] like Figure 7 and Figure 9 As shown, the difference from Embodiment 1 is that in this embodiment, the water passage 10 is configured as a single-hole water passage 13. The single-hole water passage 13 has a larger diameter than the multi-hole water passage 12, and the different water passages 12 are arranged to adapt to different water quality and flow rate treatment requirements. At this time, the water passage 10 and the pressure-bearing part 11 are arranged horizontally. The water pressure / flow rate adjustment between the water passage 10 and the water distribution platform 22, and the limiting function between the pressure-bearing part 11 and the first protrusion 23 are the same as in Embodiment 1, and will not be described again.

[0056] Example 3

[0057] like Figures 1 to 3 As shown, an aerator includes an aerator body 3 and a flow regulating structure as described in Embodiment 1 or Embodiment 2. The aerator body 3 houses the flow regulating structure and cooperates with it to form a gas-liquid mixing chamber 30 communicating with a water passage 21; specifically, the flow regulating structure is assembled in the aerator body 3 and snap-fitted into the aerator body 3.

[0058] like Figure 1 and Figure 2 As shown, the side wall of the aerator body 3 is provided with several venting grooves 31 that connect to the gas-liquid mixing chamber 30, for introducing air to form bubble water; the lower wall of the aerator body 3 is provided with several water outlet holes 33 that connect to the gas-liquid mixing chamber 30, for discharging the mixed bubble water. The aerator using this flow regulation structure achieves the dual functions of gas-liquid mixing and flow regulation, and can adapt to environments with different water pressures. The aerator body 3 and the flow regulation structure cooperate to form the gas-liquid mixing chamber 30. When water flows from the narrow water passage 21 around the flow regulation structure to the relatively spacious space of the gas-liquid mixing chamber 30, the water flow velocity increases, creating a negative pressure effect within the mixing chamber. This negative pressure state creates a pressure difference with the outside, attracting outside air to quickly enter the mixing chamber through the venting grooves 31, where it mixes thoroughly with the water flow dispersed by the flow regulation structure to form bubble water.

[0059] To optimize bubble formation and distribution, such as Figure 3As shown, the periphery of the aerator body 3 is configured with an arc-shaped guide surface 32. The gas-liquid mixed water impacts the guide surface 32 and flows downward along the guide surface 32 to the middle of the cavity wall. At least a portion of the gas-liquid mixed water rebounds upward in a direction away from the guide surface 32. In traditional designs, the periphery of the aerator body 3 is a vertical surface, which means that the water flowing out from the flow regulation structure may directly impact the bottom edge of the aerator body 3, increasing the potential risk of leakage. Furthermore, at low pressure, the air mixing effect is poor, and most of the low-pressure water flows out along the edge of the aerator body 3, with no water splash in the middle circle. The water splash often exhibits a hollow phenomenon, affecting the user experience. In this embodiment, the periphery of the aerator body 3 is configured as an arc-shaped guide surface 32. Since the water passage hole 21 is located around the water passage cavity 20, the water coming out of the water passage hole 21 mixes with the air entering from the air vent 31 on the side wall of the aerator body 3 to form a gas-liquid mixture that impacts the arc-shaped guide surface 32. The arc of the guide surface 32 effectively disperses the impact force of the water flow, allowing the water flow to flow more smoothly along the guide surface 32 and reducing the risk of leakage. The arc design causes the gas-liquid mixture to gather towards the center on the guide surface 32. During this process, the contact area between the water flow and the air increases, the mixing is more thorough, the air mixing effect is improved, and the evenly distributed water droplets avoid hollow phenomena. At the same time, at least some of the gas-liquid mixture can rebound upwards in the direction away from the guide surface 32, promoting the tumbling and re-rectification of the water flow in the inner cavity of the aerator body 3, making the water output more uniform and further improving the fineness and stability of the bubbles.

[0060] The extension 34 from the guide surface 32 to the outlet hole 33 is horizontally positioned. The lower cavity wall of the aerator body 3 extends horizontally from the arc surface of the guide surface 32 towards the outlet hole 33, forming a stable water outlet channel. During the gas-liquid mixing process, even if the internal water flow is disturbed by the mixing force, this horizontal extension 34 can effectively prevent the gas-liquid mixed water from flowing backward along the guide surface 32, especially preventing it from flowing back to the outside through the venting groove 31, thus reducing the risk of leakage.

[0061] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
