Description

Technical Field

[0001] This article relates to the field of kitchen and bathroom technology, and in particular to a water outlet device and its aerator. Background Technology

[0002] The principle of existing microbubble bubblers is to use high-speed water flow to create negative pressure to draw in air, forming a water-air mixture. The high-speed water-air mixture then impacts the bubbling filter, which cuts the air bubbles in the water-air mixture, thereby forming microbubbles in the mixture.

[0003] During long-term use, dirt in the water can clog the mesh of the bubble filter in existing microbubble aerators, causing the filter to become dirty and affecting the water output of the microbubble aerator. Summary of the Invention

[0004] The technical problem to be solved in this application is how to avoid clogging of the foaming filter.

[0005] To address the aforementioned technical problems, this application proposes a bubbler comprising:

[0006] The housing has a mounting cavity and an inlet, an outlet, and an air inlet, all of which are connected to the mounting cavity;

[0007] A foaming net, which is flexible or elastic, has its edges connected to the housing and can cover the water outlet, and is provided with a plurality of first mesh holes and a dirt outlet with a cross-sectional area larger than the first mesh holes;

[0008] An accelerator, disposed within the mounting cavity, is slidable towards and away from the foaming net, and abuts against the area of ​​the foaming net near the dirt outlet; and...

[0009] An elastic element is used to apply a spring force toward the accelerator to the area of ​​the foaming net near the dirt outlet;

[0010] The accelerator is configured to slide toward the foaming net under the action of water flow to stretch the foaming net into an arch in the direction away from the accelerator.

[0011] When water is injected into the inlet of the housing, the water flow pushes the accelerator towards the foaming net, causing the foaming net to arch away from the accelerator. When water injection stops, the elastic element pushes the foaming net and the accelerator in opposite directions. Thus, during the back-and-forth switching between water intake and stop at the inlet, the accelerator slides back and forth, causing the foaming net to move back and forth, loosening and removing scale and impurities from the foaming net. Simultaneously, when water is injected, the foaming net arches away from the accelerator, allowing the scale and impurities detached from the foaming net to move along the inclined surface of the foaming net towards the dirt outlet at the top of the foaming net, and finally be discharged from the dirt outlet. This achieves the effect of descaling and removing impurities, preventing the foaming net from becoming clogged.

[0030] like Figures 1-4 As shown, Figures 1-4 A bubbler 100 according to an embodiment of this application is shown. The bubbler 100 includes a housing 1, a bubble net 2, an air inlet frame 5, an elastic element 3, and an acceleration element 4.

[0031] like Figure 5 , 6As shown, the housing 1 has an installation cavity 104, and the housing 1 also has a water inlet 101, a water outlet 102, and an air inlet 103. The water inlet 101, water outlet 102, and air inlet 103 are all connected to the installation cavity 104. In this embodiment, the housing 1 includes an outer cylinder 11, an inner cylinder 12, and a cover 13. The outer cylinder 11 is generally cylindrical. The water inlet 101 is located at one end of the outer cylinder 11, and the end of the outer cylinder 11 facing away from the water inlet 101 has an internal thread. The inner cylinder 12 is cylindrical. The inner cylinder 12 has an external thread and is located inside the end of the outer cylinder 11 with the internal thread. The external thread of the inner cylinder 12 engages with the internal thread of the outer cylinder 11, forming a threaded connection between the inner cylinder 12 and the outer cylinder 11. The cover 13 is located at the end of the inner cylinder 12 facing away from the water inlet 101 and is fixed relative to the inner cylinder 12. A water outlet 102 is provided on the faceplate 13. The faceplate 13 and the inner cylinder 12 enclose the mounting cavity 104. An air inlet 103 is located between the end of the faceplate 13 facing away from the water inlet 101 and the end of the inner cylinder 12 facing away from the water inlet 101. The faceplate 13 includes a connecting cylinder 131 and a support frame 132. The connecting cylinder 131 has a cylindrical structure. The connecting cylinder 131 is disposed inside the inner cylinder 12 and is coaxially arranged with the inner cylinder 12. The outer peripheral wall of the connecting cylinder 131 is recessed inward to form an air inlet groove 1311. The air inlet groove 1311 extends from one end of the connecting cylinder 131 to the other end. The inner wall of the air inlet groove 1311 and the inner wall of the inner cylinder 12 enclose an air inlet channel 105. The air inlet channel 105 extends from the air inlet 103 to the mounting cavity 104. The air inlet 103 communicates with the mounting cavity 104 through the air inlet channel 105. The inlet 101 is used to connect to an external water supply pipeline. The support frame 132 covers the end of the connecting cylinder 131 facing away from the inlet 101. The outlet 102 is provided on the support frame 132. Multiple outlets 102 can be provided on the support frame 132, and the support frame 132 is preferably configured as a mesh structure.

[0032] The foaming net 2 is flexible or elastic. It can be made of flexible or elastic materials. It can be a woven mesh structure. It can be a nylon mesh. The foaming net 2 is disposed within the mounting cavity 104, with its edges fixed to the housing 1. It can be sandwiched between the support frame 132 and the air inlet frame 5. It can also be disposed within the faceplate 13, with its edges fixed to the faceplate 13. The foaming net 2 covers the water outlet 102. It has multiple first mesh openings 22 and a dirt outlet 21. Both the first mesh openings 22 and the dirt outlet 21 penetrate the foaming net 2. Multiple first mesh openings 22 are densely distributed on the foaming net 2. The cross-sectional area of ​​the dirt outlet 21 is larger than the cross-sectional area of ​​the first mesh openings 22. The dirt outlet 21 can be located in the central region of the foaming net 2.

[0033] An air intake frame 5 is disposed within the mounting cavity 104 of the housing 1 and is fixed to the housing 1. The air intake frame 5 is located on the side of the foaming net 2 near the water inlet 101 of the housing 1, separated by the foaming net 2 and the water inlet 101. The air intake frame 5 is provided with a mixing channel 51 and an air intake hole 52. The mixing channel 51 extends from one end of the air intake frame 5 facing the water inlet 101 of the housing 1 to the other end of the air intake frame 5 facing the water outlet 102 of the housing 1. The end of the mixing channel 51 facing the water inlet 101 has an inlet connected to the water inlet 101 of the housing 1. The end of the mixing channel 51 facing the water outlet 102 has an outlet facing the foaming net 2. The mixing channel 51 is connected to the water outlet 102 through a first mesh 22 and a dirt outlet 21 on the foaming net 2. The extension direction of the air intake 52 and the extension direction of the mixing channel 51 can be perpendicular to each other or inclined to each other. One end of the air intake 52 is connected to the inlet of the mixing channel 51, and the other end of the air intake 52 is connected to one end of the air intake channel 105 extending to the mounting cavity 104. The air intake 52 is connected to the air inlet 103 of the housing 1 through the air intake channel 105.

[0034] Accelerator 4 is disposed within mounting cavity 104. Accelerator 4 is slidably connected to air intake frame 5. Accelerator 4 can slide both toward and away from foaming net 2. Accelerator 4 abuts against the area of ​​foaming net 2 near dirt outlet 21, or it can abut against the periphery of dirt outlet 21. Accelerator 4 can accelerate the water flow entering mounting cavity 104 of housing 1 from water inlet 101, and input the accelerated water flow into the inlet of mixing channel 51 of air intake frame 5. Accelerator 4 can also slide toward foaming net 2 under the action of water flow to arch foaming net 2 toward the direction away from accelerator 4.

[0035] The elastic element 3 is elastic. The elastic element 3 can be a spring. The elastic element 3 is connected to the housing 1. The elastic element 3 can be located on the side of the foaming net 2 facing away from the accelerator 4. The elastic element 3 is sandwiched between the support frame 132 of the cover 13 and the foaming net 2. The elastic element 3 abuts against the area of ​​the foaming net 2 near the dirt outlet 21. The elastic element 3 is in an elastically compressed state to apply a spring force to the area of ​​the foaming net 2 near the dirt outlet 21, the direction of which is towards the accelerator 4.

[0036] When using the aerator 100, water is injected into the inlet 101 of the housing 1. The accelerator 4 accelerates the water flow from the inlet 101 and directs the accelerated water flow into the inlet of the mixing channel 51 of the air intake frame 5. Due to the high water flow velocity at the inlet of the mixing channel 51, the pressure at the inlet of the mixing channel 51 is negative, meaning the pressure at the inlet is less than atmospheric pressure. Under the action of atmospheric pressure, outside air enters from the air inlet 103 of the housing 1 into the air intake 52, and then from the air intake 52 into the inlet of the mixing channel 51. The air mixes with the high-speed water flow at the inlet of the mixing channel 51 to form a water-air mixture, which enters the mixing channel 51 and is then sprayed towards the aerator 2 through the outlet of the mixing channel 51. In this way, the air intake frame 5 can use the negative pressure generated by the accelerated water flow to draw in outside air from the air inlet 103, so that the water flow and air are mixed into a water-air mixture, and then spray the water-air mixture towards the aerator 2. The foaming net 2 cuts the air bubbles in the water-air mixture that pass through the first mesh 22, thereby forming microbubbles in the water-air mixture. The fluid with microbubbles is finally output from the outlet 102 to the housing 1.

[0037] When water is injected into the inlet 101 of the housing 1, the water flow pushes the accelerator 4 towards the foaming net 2 and stretches the foaming net 2 into an arch facing away from the accelerator 4. When water injection into the inlet 101 of the housing 1 stops, the elastic element 3 pushes the foaming net 2 and the accelerator 4 to move in opposite directions. In this way, during the back-and-forth switching between water injection and water stop at the inlet 101, the accelerator 4 can slide back and forth and drive the foaming net 2 to move back and forth, causing the scale and impurities on the foaming net 2 to loosen and peel off. At the same time, when water is injected into the inlet 101, the foaming net 2 arches away from the accelerator 4, so that the scale and impurities that have detached from the foaming net 2 can move along the inclined surface of the foaming net 2 under the action of the water flow towards the dirt outlet 21 at the top of the foaming net 2, and finally be discharged from the dirt outlet 21, thereby achieving the effect of descaling and removing impurities.

[0038] In one illustrative embodiment, such as Figure 3 As shown, the dirt outlet 21 is located in the middle of the foaming net 2.

[0039] The dirt outlet 21 is located in the middle of the foaming net 2. The accelerating element 4 and the elastic element 3 both abut against the middle area of ​​the foaming net 2, which is conducive to uniform deformation of the foaming net 2 and reduces the likelihood of blind spots in descaling. The foaming net 2 is also evenly stressed, extending its service life. At the same time, the foaming net 2 can be stretched into a roughly conical shape by the accelerating element 4, allowing dirt detached from all parts of the foaming net 2 to be discharged smoothly.

[0040] In one illustrative embodiment, such as Figure 3As shown, multiple foaming nets 2 are provided, for example, four. The multiple foaming nets 2 are stacked sequentially between the accelerating member 4 and the elastic member 3. Each foaming net 2 is provided with a dirt outlet 21. The dirt outlets 21 on the multiple foaming nets 2 are aligned in the stacking direction of the multiple foaming nets 2.

[0041] Multiple foaming nets 2 are sandwiched between the accelerating member 4 and the elastic member 3, with the accelerating member 4 and the elastic member 3 respectively abutting against their nearest foaming net 2. The multiple layers of foaming nets 2 cut the air bubbles in the water-air mixture into denser microbubbles, increasing the amount of bubbles. At the same time, the dirt outlets 21 on the multiple foaming nets 2 are aligned with each other, allowing dirt to be discharged outward sequentially through the dirt outlets 21 on the multiple foaming nets 2.

[0042] Existing microbubble technologies all employ extremely fine accelerating orifices to accelerate water flow. These small orifices are costly to manufacture and prone to clogging and scale buildup. Clogged orifices reduce water flow velocity, affecting air intake and the ability of the filter screen to cut microbubbles. To address this issue, this application incorporates the following improvements:

[0043] like Figure 6 , 8 As shown in Figures 9 and 10, an installation groove 54 is provided at one end of the air intake frame 5 facing the water inlet 101 of the housing 1. The installation groove 54 is located in the middle of the end of the air intake frame 5 facing the water inlet 101 of the housing 1. The installation groove 54 can be a shallow groove. The bottom of the installation groove 54 can be flat. The bottom of the installation groove 54 can be perpendicular to the water inlet direction of the water inlet 101 of the housing 1. The opening of the installation groove 54 faces the water inlet 101 of the housing 1.

[0044] The mixing channel 51 of the air inlet frame 5 extends from the edge of the bottom of the mounting groove 54 to one end of the air inlet frame 5 facing the outlet 102. The mixing channel 51 can be a straight channel perpendicular to the bottom of the mounting groove 54 and parallel to the water inlet direction of the inlet 101.

[0045] The air intake frame 5 is also equipped with a slide 53. The slide 53 is a straight through hole, extending from the middle of the bottom of the mounting groove 54 to the middle of the end of the air intake frame 5 facing the outlet 102. The extension direction of the slide 53 is parallel to the extension direction of the mixing channel 51.

[0046] The accelerator 4 includes a pressure plate 41 and a support column 42. The pressure plate 41 may be flat. The surface of the pressure plate 41 is parallel to the bottom of the mounting groove 54 of the air intake frame 5 and perpendicular to the water inlet 101 of the mounting groove 54. The pressure plate 41 is at least partially contained within the mounting groove 54. There is a gap between the pressure plate 41 and the mounting groove 54. The thickness of the pressure plate 41 may be less than the depth of the mounting groove 54. The support column 42 is straight. The support column 42 is perpendicular to the pressure plate 41. One end of the support column 42 is connected to the middle of the pressure plate 41. The support column 42 may be a hollow tubular structure. The support column 42 passes through the slide rail 53 of the air intake frame 5, and the support column 42 can slide along the extension direction of the slide rail 53 to achieve a sliding connection between the accelerator 4 and the air intake frame 5. The end of the support column 42 facing away from the pressure plate 41 abuts against the area of ​​the foaming net 2 near the dirt outlet 21.

[0047] The side of the pressure plate 41 and the side of the mounting groove 54 enclose an acceleration channel 50. One end of the acceleration channel 50 is connected to the water inlet 101 of the shell 1. The other end of the acceleration channel 50 faces the inlet of the mixing channel 51. The cross-sectional area of ​​the acceleration channel 50 is smaller than that of the mixing channel 51, and the cross-sectional area of ​​the acceleration channel 50 is also smaller than the area of ​​the water inlet 101 of the shell 1.

[0048] In this way, after the water flow enters the mounting cavity 104 from the inlet 101 of the housing 1, it applies pressure to the pressure plate 41 to push the accelerator 4 so that the accelerator 4 can slide towards the foaming net 2 along the extension direction of the slide 53, and the support column 42 expands the foaming net 2 into an arch facing away from the accelerator 4, and the elastic member 3 is further compressed. Since the cross-sectional area of ​​the acceleration channel 50 is relatively small, a narrowing is formed at the acceleration channel 50, and the water flow can be accelerated when flowing through the acceleration channel 50. The accelerated water flow is sprayed to the inlet of the mixing channel 51, thereby creating a negative pressure at the inlet, and using this negative pressure to draw in air from the air inlet 103. In particular, under the action of water pressure and elastic element 3, the accelerator 4 can slide back and forth relative to the air intake frame 5, and the side of the pressure plate 41 and the side of the mounting groove 54 can move relative to each other, which can remove the scale and impurities in the acceleration channel 50. These scale and impurities can be discharged from the dirt outlet 21 and the water outlet 102 to the outside of the housing 1 with the water flow, avoiding the acceleration channel 50 from getting dirty and clogged.

[0049] In one illustrative embodiment, such as Figure 7As shown, a mixing chamber is formed between the foaming net 2 and the air intake frame 5. A second groove 55 is provided on the end of the air intake frame 5 facing the foaming net 2. The foaming net 2 covers the opening of the second groove 55, and the inner wall of the second groove 55 and the surface of the foaming net 2 facing the second groove 55 form the mixing chamber. The gap between the slide 53 and the support column 42 forms a first return channel 40. One end of the first return channel 40 connects to the mixing chamber. The gap between the bottom of the mounting groove 54 and the pressure plate 41 forms a second return channel 60. The end of the first return channel 40 facing away from the mixing chamber connects to one end of the second return channel 60. The end of the second return channel 60 facing away from the first return channel 40 connects to the inlet of the mixing channel 51.

[0050] In this way, when water is injected into the inlet 101, the accelerated water flow is sprayed from the acceleration channel 50 to the inlet of the mixing channel 51, creating a negative pressure at the inlet. The water-air mixture flows through the mixing channel 51 and enters the mixing chamber. Driven by the water pressure, a portion of the water-air mixture in the mixing chamber flows back along the first return channel 40 and the second return channel 60 to the inlet of the mixing channel 51, where it is cut into more microbubbles by the high-speed water flow sprayed from the acceleration channel 50. Thus, the water-air mixture circulates in the mixing channel 51, the mixing chamber, the first return channel 40, and the second return channel 60, further increasing the amount of microbubbles. At the same time, during circulation, a portion of the water-air mixture can also carry the dirt that has fallen off the foaming net 2 in the mixing chamber to the dirt outlet 21, allowing the dirt to be quickly discharged.

[0051] In one illustrative embodiment, such as Figure 8-10 As shown, the side of the pressure plate 41 is recessed inward to form a first groove 411. The shape of the cross-section of the first groove 411 is not limited. The first groove 411 extends from one surface of the pressure plate 41 to the other surface, and the first groove 411 penetrates the pressure plate 41 vertically. The side of the mounting groove 54 covers the opening of the first groove 411, and the inner wall of the first groove 411 and the side of the mounting groove 54 enclose an acceleration channel 50. Multiple first grooves 411 are provided on the pressure plate 41, and the multiple first grooves 411 are evenly distributed around the circumference of the pressure plate 41. The mixing channel 51 is constructed as an annular channel, and the cross-section of the mixing channel 51 can be circular. The mixing channel 51 surrounds the slide 53 and surrounds the first return channel 40. The multiple first grooves 411 on the pressure plate 41 are all aligned with the inlet of the mixing channel 51.

[0052] In this way, the multiple acceleration channels 50 surrounding the pressure plate 41 can uniformly spray high-speed water into the inlet of the annular mixing channel 51 in the circumferential direction. Consequently, the outlet of the annular mixing channel 51 can uniformly output a water-air mixture. A portion of this water-air mixture flows back into the first return channel 40, carrying dirt from the edge of the foaming net 2 towards the dirt outlet 21. This ensures that dirt detached from various parts of the foaming net 2 is carried to the dirt outlet 21, resulting in more thorough dirt removal. Simultaneously, the cross-section of the acceleration channel 50 in this structure can be set to be relatively large, making it less prone to clogging. Alternatively, the cross-section of the acceleration channel 50 can be set to be relatively small; for example, the width and depth of the first groove 411 can both be set below 0.3 mm. Even with a small cross-section, the acceleration member 4 can reciprocate relative to the air intake frame 5, removing accumulated dirt and impurities from the acceleration channel 50, preventing clogging.

[0053] In another illustrative embodiment, such as Figure 11-13 As shown, the width between the side of the pressure plate 41 and the side of the mounting groove 54 is the same, and the acceleration channel 50 is constructed as a uniformly wide annular channel. The mixing channel 51 is also constructed as an annular channel, and the inlet of the acceleration channel 50 is aligned with the inlet of the mixing channel 51. The mixing channel 51 surrounds the slide 53 and also surrounds the first return channel 40. In this embodiment, the mounting groove 54 is constructed as a circular recess, the pressure plate 41 is constructed as a disc, and the mounting groove 54, the pressure plate 41, the mixing channel 51, the slide 53, and the dirt outlet 21 are coaxially arranged.

[0054] In this way, the annular acceleration channel 50 can uniformly spray high-speed water into the inlet of the annular mixing channel 51 in the circumferential direction, and the outlet of the annular mixing channel 51 can uniformly output water-air mixture fluid. When a portion of this water-air mixture fluid flows back into the first return channel 40, it carries dirt from the edge of the foaming net 2 to the dirt outlet 21, thereby carrying all the dirt that has fallen off from the foaming net 2 to the dirt outlet 21, which can remove dirt more thoroughly. At the same time, the cross-section of the acceleration channel 50 with this structure can be set to be large, so that the acceleration channel 50 is not easy to get dirty and clogged. The cross-section of the acceleration channel 50 with this structure can also be set to be small. For example, the width between the side of the pressure plate 41 and the side of the mounting groove 54 is set to less than 0.3mm. Even if the cross-section of the acceleration channel 50 is set very small, since the acceleration component 4 can slide back and forth relative to the air intake frame 5 to remove the accumulated dirt and impurities in the acceleration channel 50, the acceleration channel 50 with a small cross-section will not get dirty and clogged.

[0055] In one illustrative embodiment, the air intake frame 5 has multiple air intake holes 52, which are located on the outside of the mixing channel 51 and evenly arranged around the circumference of the mixing channel 51. The outer peripheral wall of the connecting cylinder 131 has multiple air intake grooves 1311, which are evenly arranged around the circumference of the connecting cylinder 131. The inner walls of the multiple air intake grooves 1311 and the inner wall of the inner cylinder 12 enclose multiple air intake channels 105. The housing 1 also has multiple air inlets 103, one end of each of the multiple air intake channels 105 is connected to one of the multiple air inlets 103, and the other end of each of the multiple air intake channels 105 is connected to one of the multiple air intake holes 52. Thus, the multiple air inlets 103 can evenly deliver airflow to the inlet of the mixing channel 51 through the multiple air intake channels 105 and the multiple air intake holes 52.

[0056] In one illustrative embodiment, such as Figure 6 , 8 As shown, the support column 42 abuts against the edge of the dirt outlet 21 of the foaming net 2, and the end of the support column 42 abutting against the foaming net 2 is provided with a connecting groove 421. The mixing chamber is connected to the dirt outlet 21 through the connecting groove 421.

[0057] In this way, the fluid and dirt in the mixing chamber can enter the dirt outlet 21 of the foaming net 2 through the connecting groove 421 on the support column 42, and be discharged from the dirt outlet 21, thus avoiding the support column 42 from blocking the dirt outlet 21.

[0058] In one illustrative embodiment, the accelerating member 4 further includes a plurality of limiting protrusions 43. The plurality of limiting protrusions 43 are all disposed on the outer peripheral surface of the support column 42. The limiting protrusions 43 may be straight strip-shaped protrusions. The limiting protrusions 43 are parallel to the support column 42, and the plurality of limiting protrusions 43 are clearance-fitted with the slide rail 53. The plurality of limiting protrusions 43 are evenly distributed along the circumference of the support column 42, and the first return channel 40 is formed between two adjacent limiting protrusions 43.

[0059] The clearance fit between the multiple limiting protrusions 43 and the slide rail 53 enables a more stable sliding connection between the accelerator 4 and the air intake frame 5. The accelerator 4 can slide more stably along the slide rail 53 of the air intake frame 5. At the same time, the size of the first return channel 40 remains constant during the reciprocating sliding of the accelerator 4.

[0060] In one illustrative embodiment, such as Figure 4 , 6As shown, the aerator 100 also includes a filter screen 6. The filter screen 6 is disposed between the accelerator 4 and the water inlet 101 of the housing 1, and between the air intake frame 5 and the water inlet 101 of the housing 1. The filter screen 6 includes a base 61 and a filter part 62. The base 61 is annular and fixed to the housing 1. The base 61 has a water passage 611 with one end connected to the water inlet 101. The filter part 62 is a mesh structure and covers the end of the water passage 611 of the base near the water inlet 101 of the housing 1.

[0061] The air intake frame 5 also includes a water-blocking protrusion 45, which is disposed on the surface of the pressure plate 41 facing the water passage 611 of the base 61.

[0062] When the pressure plate 41 of the accelerator 4 is not under water pressure, it covers the end of the water passage 611 of the base 61 facing away from the water inlet 101 of the housing 1. The water-blocking protrusion 45 extends into the water passage 611 and extends along the end edge of the water passage 611.

[0063] In this way, the water flowing into the inlet 101 is first filtered through the filter screen 62 of the filter screen 6 to remove large particles of impurities. The filtered water then enters the water passage 611 of the base 61, pushing the pressure plate 41 towards the aerator 2 and creating a gap between the pressure plate 41 and the base 61. The water can then continue to flow into the acceleration channel 50 through this gap. When the water pressure at the inlet 101 is low, the water-blocking protrusion 45 can hold back the water flow, increasing the water pressure on the pressure plate 41. This allows the water to push the pressure plate 41 towards the aerator 2, preventing the water flow in the water passage 611 from being unable to push the aerator 2 when the water pressure at the inlet 101 is low, thus avoiding a low water output from the aerator 100.

[0064] In one illustrative embodiment, such as Figure 7 , 9 As shown, the water-blocking ridge 45 is constructed as an annular protrusion and is coaxial with the water passage 611 of the base 61. The water-blocking ridge 45 is provided with multiple notches 451, which can be evenly distributed in the circumferential direction of the water-blocking ridge 45.

[0065] Water in the water passage 611 of the base 61 can flow out of the water-blocking protrusion 45 through the notch 451 on the water-blocking protrusion 45, reducing the resistance of the water-blocking protrusion 45 to the water flow and increasing the water output of the aerator 100.

[0066] In one illustrative embodiment, such as Figure 7As shown, the outer cylinder 11 has a first positioning shoulder 110 located on the side of the internal thread of the outer cylinder 11 near the water inlet 101. The housing 1 also includes a sealing gasket 14. The sealing gasket 14 can be an annular gasket. The sealing gasket 14 is sandwiched between the inner cylinder 12 and the first positioning shoulder 110. The sealing gasket 14 can prevent water from leaking from the gap between the outer cylinder 11 and the inner cylinder 12.

[0067] In one illustrative embodiment, such as Figure 6 As shown, a second positioning shoulder 121 is provided on the inner wall of the inner cylinder 12, and the outer edge of the air intake frame 5 and the outer edge of the face cover 13 are sandwiched between the second positioning shoulder 121 and the sealing gasket 14.

[0068] In this way, the outer edge of the air intake frame 5 and the outer edge of the face cover 13 are sandwiched between the second positioning shoulder 121 and the sealing gasket 14, and the air intake frame 5 and the face cover 13 can be firmly fixed in the mounting cavity 104 and cannot move relative to the inner cylinder 12. This assembly method is simple and reliable.

[0069] This application also proposes a water outlet device, which can be a faucet, shower head, showerhead, or other device capable of discharging water. The water outlet device includes an aerator 100 as described above. The water outlet device discharging water through the aerator 100 generates microbubbles in the water flow. Simultaneously, the aerator 100 of the water outlet device is self-cleaning and will not become clogged.
