Description

Technical Field

[0001] The present invention relates to the field of kitchen and bathroom technology, and in particular to a water outlet device and a bubbler thereof. Background Art

[0002] The principle of the existing microbubble bubbler is to use high-speed water flow to form negative pressure to inhale air to form a water-gas mixed fluid, and then the high-speed water-gas mixed fluid impacts the bubble filter, and the bubble filter cuts the bubbles in the water-gas mixed fluid, thereby forming microbubbles in the water-gas mixed fluid.

[0003] During the long-term use of the existing micro-bubble bubbler, the dirt in the water will block the mesh of the bubble filter, causing the bubble filter to be dirty and blocked, thereby affecting the water output of the micro-bubble bubbler. Summary of the invention

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

[0005] In order to solve the above technical problems, the present application proposes a bubbler, which comprises: A shell body, provided with an installation cavity and a water inlet, a water outlet and an air inlet all connected to the installation cavity; A foaming net is flexible or elastic, has an edge connected to the shell 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; an accelerator, arranged in the installation cavity, capable of sliding toward and away from the foaming net, and abutting against a region of the foaming net close to the dirt outlet; and an elastic member, used for applying an elastic force toward the acceleration member to the area of ​​the foaming net close to the dirt outlet; Wherein, the acceleration member is configured to slide toward the bubbling net under the action of water flow so as to support the bubbling net to be arched in a direction away from the acceleration member.

[0006] When water is injected into the water inlet of the shell, the water flow pushes the accelerator to slide in the direction of the bubble net and props the bubble net to be arched in the direction away from the accelerator. When water is stopped from being injected into the water inlet of the shell, the elastic member pushes the bubble net and the accelerator to move in opposite directions. In this way, during the process of switching between the water inlet and the water inlet, the accelerator can slide back and forth and drive the bubble net to move back and forth, so that the scale and impurities on the bubble net are loosened and peeled off. At the same time, when water is injected into the water inlet, the bubble net arches in the direction away from the accelerator, so that the scale and impurities separated from the bubble net can move along the inclined surface of the bubble net to the dirt outlet at the top of the bubble net under the drive of the water flow, and finally be discharged from the dirt outlet, thereby achieving the effect of removing scale and impurities and avoiding the bubble net from being dirty and blocked.

Other advantages of the present application can be realized and obtained by the schemes described in the description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] like Figures 1 to 4 As shown, Figures 1 to 4 A bubbler 100 in an embodiment of the present application is shown. The bubbler 100 comprises a housing 1, a bubbler net 2, an air inlet frame 5, an elastic member 3 and an acceleration member 4.

[0014] like Figure 5 , 6As shown, a mounting cavity 104 is provided in the housing 1, and a water inlet 101, a water outlet 102 and an air inlet 103 are also provided on the housing 1. The water inlet 101, the water outlet 102 and the air inlet 103 are all connected to the mounting 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 configured as a roughly circular tube. The water inlet 101 is provided at one end of the outer cylinder 11, and an inner thread is provided at one end of the outer cylinder 11 facing away from the water inlet 101. The inner cylinder 12 is configured as a cylindrical shape. The inner cylinder 12 is provided with an outer thread, and the inner cylinder 12 is provided in one end of the outer cylinder 11 provided with an inner thread, and the outer thread of the inner cylinder 12 is screwed into the inner thread of the outer cylinder 11 so that the inner cylinder 12 and the outer cylinder 11 form a threaded connection. The cover 13 is located at one end of the inner cylinder 12 facing away from the water inlet 101, and is relatively fixed to the inner cylinder 12. The water outlet 102 is arranged on the face cover 13. The face cover 13 and the inner tube 12 enclose an installation cavity 104. The air inlet 103 is located between one end of the face cover 13 facing away from the water inlet 101 and one end of the inner tube 12 facing away from the water inlet 101. The face cover 13 includes a connecting tube 131 and a support frame 132. The connecting tube 131 is configured as a cylindrical structure. The connecting tube 131 is arranged in the inner tube 12 and is coaxially arranged with the inner tube 12. The outer peripheral wall of the connecting tube 131 is recessed inward to form an air inlet groove 1311. The air inlet groove 1311 extends from one end of the connecting tube 131 to the other end. The inner wall of the air inlet groove 1311 and the inner wall of the inner tube 12 enclose an air inlet channel 105. The air inlet channel 105 extends from the air inlet 103 to the installation cavity 104. The air inlet 103 is connected to the installation cavity 104 through the air inlet channel 105. The water inlet 101 is used to connect to an external water supply pipeline. The support frame 132 covers the end of the connecting tube 131 facing away from the water inlet 101. The water outlet 102 is arranged on the support frame 132. A plurality of water outlets 102 may be arranged on the support frame 132, and the support frame 132 is preferably arranged in a mesh structure.

[0015] The bubbling net 2 is flexible or elastic. The bubbling net 2 can be made of a flexible material or an elastic material. The bubbling net 2 can be a mesh structure woven from fabric. The bubbling net 2 can be a nylon net. The bubbling net 2 is arranged in the installation cavity 104, and the edge of the bubbling net 2 is fixed on the housing 1. The bubbling net 2 can be sandwiched between the support frame 132 and the air inlet frame 5. The bubbling net 2 can be arranged in the face cover 13 and its edge is fixed on the face cover 13. The bubbling net 2 can cover the water outlet 102. The bubbling net 2 is provided with a plurality of first mesh holes 22 and a dirt outlet 21. The first mesh holes 22 and the dirt outlet 21 both penetrate the bubbling net 2. The plurality of first mesh holes 22 are densely distributed on the bubbling net 2. The cross-sectional area of ​​the dirt outlet 21 is greater than the cross-sectional area of ​​the first mesh holes 22. The dirt outlet 21 can be arranged in the middle area of ​​the bubbling net 2.

[0016] The air inlet frame 5 is arranged in the installation cavity 104 of the shell 1, and the air inlet frame 5 is fixed on the shell 1. The air inlet frame 5 is located on the side of the bubbling net 2 close to the water inlet 101 of the shell 1, and is separated between the bubbling net 2 and the water inlet 101. The air inlet frame 5 is provided with a mixing channel 51 and an air suction hole 52. The mixing channel 51 extends from one end of the air inlet frame 5 facing the water inlet 101 of the shell 1 to one end of the air inlet frame 5 facing the water outlet 102 of the shell 1. An inlet is provided at one end of the mixing channel 51 facing the water inlet 101, and the inlet is connected with the water inlet 101 of the shell 1. An outlet is provided at one end of the mixing channel 51 facing the water outlet 102, and the outlet faces the bubbling net 2. The mixing channel 51 is connected with the water outlet 102 through the first mesh 22 and the dirt outlet 21 on the bubbling net 2. The extending direction of the air intake hole 52 and the extending direction of the mixed flow channel 51 can be perpendicular to each other or can be inclined to each other. One end of the air intake hole 52 is connected to the entrance of the mixed flow channel 51, and the other end of the air intake hole 52 is connected to one end of the air inlet channel 105 extending to the installation cavity 104. The air intake hole 52 is connected to the air inlet port 103 of the housing 1 through the air inlet channel 105.

[0017] The accelerator 4 is arranged in the installation cavity 104. The accelerator 4 is slidably connected to the air inlet frame 5. The accelerator 4 can slide in the direction toward the bubbling net 2 and can also slide in the direction away from the bubbling net 2. The accelerator 4 abuts against the area of ​​the bubbling net 2 close to the dirt outlet 21, and the accelerator 4 can abut against the periphery of the dirt outlet 21. The accelerator 4 can accelerate the water flow input from the water inlet 101 into the installation cavity 104 of the shell 1, and input the accelerated water flow into the entrance of the mixed flow channel 51 of the air inlet frame 5. The accelerator 4 can also slide in the direction toward the bubbling net 2 under the action of the water flow to support the bubbling net 2 to be arched in the direction away from the accelerator 4.

[0018] The elastic member 3 is elastic. The elastic member 3 may be a spring. The elastic member 3 is connected to the housing 1. The elastic member 3 may be arranged on the side of the foaming net 2 facing away from the accelerator 4. The elastic member 3 is sandwiched between the support frame 132 of the cover 13 and the foaming net 2. The elastic member 3 abuts against the area of ​​the foaming net 2 near the dirt outlet 21. The elastic member 3 is in an elastically compressed state to apply an elastic force to the area of ​​the foaming net 2 near the dirt outlet 21, and the direction of the elastic force is toward the accelerator 4.

[0019] When the bubbler 100 is used, water is injected into the water inlet 101 of the housing 1. The accelerator 4 can accelerate the water flow input from the water inlet 101, and input the accelerated water flow into the entrance of the mixed flow channel 51 of the air inlet frame 5. Since the water flow velocity at the entrance of the mixed flow channel 51 is high, the pressure at the entrance of the mixed flow channel 51 is negative pressure, that is, the pressure at the entrance is less than the atmospheric pressure. Under the action of atmospheric pressure, the outside air enters the air inlet 103 of the housing 1 into the air suction hole 52, and then enters the entrance of the mixed flow channel 51 from the air suction hole 52. The air mixes with the high-speed water flow at the entrance of the mixed flow channel 51 to form a water-gas mixed fluid, enters the mixed flow channel 51, and then is ejected toward the bubble net 2 through the outlet of the mixed flow channel 51. In this way, the air inlet frame 5 can use the negative pressure generated by the accelerated water flow to inhale the outside air from the air inlet 103 so that the water flow and air are mixed into a water-gas mixed fluid, and the water-gas mixed fluid is ejected toward the bubble net 2. The bubbling net 2 cuts the bubbles in the water-gas mixed fluid passing through the first mesh 22 , thereby forming microbubbles in the water-gas mixed fluid. The fluid with microbubbles is finally output from the housing 1 from the water outlet 102 .

[0020] When water is injected into the water inlet 101 of the housing 1, the water flow pushes the accelerator 4 to slide in the direction of the bubbling net 2 and props the bubbling net 2 to arch in the direction away from the accelerator 4. When water is stopped from being injected into the water inlet 101 of the housing 1, the elastic member 3 pushes the bubbling net 2 and the accelerator 4 to move in opposite directions. In this way, during the process of switching between the water inlet 101 and the water inlet stopping, the accelerator 4 can slide back and forth and drive the bubbling net 2 to move back and forth, so that the scale and impurities on the bubbling net 2 are loosened and peeled off. At the same time, when water is injected into the water inlet 101, the bubbling net 2 arches in the direction away from the accelerator 4, so that the scale and impurities separated from the bubbling net 2 can move along the surface of the inclined bubbling net 2 to the dirt outlet 21 at the top of the bubbling net 2 under the drive of the water flow, and finally be discharged from the dirt outlet 21, thereby achieving the effect of removing scale and impurities.

[0021] In an illustrative embodiment, Figure 3 As shown, the dirt outlet 21 is arranged in the middle of the foaming net 2.

[0022] The dirt outlet 21 is arranged in the middle of the foaming net 2, and the accelerating member 4 and the elastic member 3 are both against the middle area of ​​the foaming net 2, which is conducive to uniform deformation of the foaming net 2, and it is not easy to have a blind spot for dirt removal. The foaming net 2 is also uniformly stressed at all places, which prolongs the service life of the foaming net 2. At the same time, the foaming net 2 can be supported by the accelerating member 4 into a roughly conical shape, and the dirt peeled off from all parts of the foaming net 2 can be discharged smoothly.

[0023] In an illustrative embodiment, Figure 3As shown, there are multiple, for example, four, foaming nets 2. The multiple foaming nets 2 are stacked and arranged in sequence between the acceleration member 4 and the elastic member 3. A dirt outlet 21 is provided on each foaming net 2. The dirt outlets 21 on the multiple foaming nets 2 are aligned in the stacking direction of the multiple foaming nets 2.

[0024] The plurality of bubbling nets 2 are sandwiched between the accelerator 4 and the elastic member 3, and the accelerator 4 and the elastic member 3 are respectively in contact with the closest bubbling nets 2. The plurality of bubbling nets 2 cut the bubbles in the water-gas mixed fluid into denser microbubbles, thereby increasing the amount of bubbles. At the same time, the dirt outlets 21 on the plurality of bubbling nets 2 are aligned with each other, and the dirt can be discharged outward through the dirt outlets 21 on the plurality of bubbling nets 2 in sequence.

[0025] Existing microbubble technologies all use extremely small acceleration holes to accelerate water flow. Small acceleration holes have high processing costs and are prone to clogging and fouling. When the acceleration holes are dirty and clogged, the water flow rate will be reduced, affecting the suction effect and the effect of impacting the filter screen to cut microbubbles. To solve this problem, this application also makes the following improvements:

[0026] like Figure 6 , 8 As shown in FIGS. 9 and 10 , a mounting groove 54 is provided at one end of the air intake frame 5 facing the water inlet 101 of the housing 1. The mounting groove 54 is provided in the middle of the end of the air intake frame 5 facing the water inlet 101 of the housing 1. The mounting groove 54 may be a shallow groove. The bottom of the mounting groove 54 may be a plane. The bottom of the mounting groove 54 may be perpendicular to the water inlet direction of the water inlet 101 of the housing 1. The opening of the mounting groove 54 faces the water inlet 101 of the housing 1.

[0027] The mixed flow channel 51 of the air intake frame 5 extends from the edge of the bottom of the mounting groove 54 to one end of the air intake frame 5 facing the water outlet 102. The mixed flow 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 water inlet 101.

[0028] The air intake frame 5 is also provided with a slideway 53. The slideway 53 is a straight through hole, and extends from the middle of the bottom of the mounting groove 54 to the middle of one end of the air intake frame 5 facing the water outlet 102. The extension direction of the slideway 53 is parallel to the extension direction of the mixing channel 51.

[0029] The accelerator 4 includes a pressure plate 41 and a support column 42. The pressure plate 41 may be constructed in the shape of a flat plate. The plate surface of the pressure plate 41 is parallel to the bottom of the mounting groove 54 of the air intake frame 5, and is perpendicular to the water inlet direction of the water inlet 101 of the mounting groove 54. The pressure plate 41 is at least partially accommodated in 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 constructed in the shape of a straight bar. 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 is arranged in the slideway 53 of the air intake frame 5, and the support column 42 can slide along the extension direction of the slideway 53 to realize the sliding connection between the accelerator 4 and the air intake frame 5. One end of the support column 42 facing away from the pressure plate 41 abuts against the area of ​​the foaming net 2 close to the dirt outlet 21 .

[0030] 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 housing 1. The other end of the acceleration channel 50 faces the entrance of the mixed flow channel 51. The cross-sectional area of ​​the acceleration channel 50 is smaller than the cross-sectional area of ​​the mixed flow 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 housing 1.

[0031] In this way, after the water flows from the water inlet 101 of the housing 1 into the installation cavity 104, it applies pressure to the pressure plate 41 to push the accelerator 4 so that the accelerator 4 can slide toward the foaming net 2 along the extension direction of the slideway 53, and the support column 42 props the foaming net 2 to arch in the direction away from the accelerator 4, and the elastic member 3 is further compressed. Since the cross-sectional area at the acceleration channel 50 is relatively small, a constriction is formed at the acceleration channel 50, and the water flow can be accelerated when flowing through the acceleration channel 50, and the accelerated water flow is sprayed to the entrance of the mixing channel 51, thereby forming a negative pressure at the entrance, and using the negative pressure to inhale air from the air inlet 103. In particular, under the action of water pressure and the elastic member 3, the acceleration member 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, so as to 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 shell 1 along with the water flow, so as to avoid the acceleration channel 50 being dirty and blocked.

[0032] In an illustrative embodiment, Figure 7As shown, a mixing flow chamber 104 is enclosed between the bubble net 2 and the air inlet frame 5. A second groove 55 is provided on one end of the air inlet frame 5 facing the bubble net 2, and the bubble net 2 covers the opening of the second groove 55. The inner wall of the second groove 55 and the surface of the bubble net 2 facing the second groove 55 enclose the mixing flow chamber 104. The gap between the slide 53 and the support column 42 forms a first reflux channel 40. One end of the first reflux channel 40 is connected to the mixing flow chamber 104. The gap between the bottom of the mounting groove 54 and the pressure plate 41 forms a second reflux channel 60. One end of the first reflux channel 40 facing away from the mixing flow chamber 104 is connected to one end of the second reflux channel 60. One end of the second reflux channel 60 facing away from the first reflux channel 40 is connected to the entrance of the mixing flow channel 51.

[0033] In this way, when water is injected into the water inlet 101, the accelerated water flow is ejected from the acceleration channel 50 to the entrance of the mixing channel 51 to form a negative pressure at the entrance. The water-gas mixed fluid flows through the mixing channel 51 and enters the mixing chamber 104. Driven by the water pressure, a part of the water-gas mixed fluid in the mixing chamber 104 flows back to the entrance of the mixing channel 51 along the first reflux channel 40 and the second reflux channel 60, and is cut into more microbubbles by the high-speed water flow ejected from the acceleration channel 50. Thus, the water-gas mixed fluid circulates in the mixing channel 51, the mixing chamber 104, the first reflux channel 40, and the second reflux channel 60, which can further increase the amount of microbubbles. At the same time, a part of the water-gas mixed fluid can also carry the dirt that falls off the bubbling net 2 in the mixing chamber 104 to the dirt outlet 21 during circulation, so that the dirt can be quickly discharged.

[0034] In an illustrative embodiment, 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 plate surface of the pressure plate 41 to another plate surface, and the first groove 411 vertically penetrates the pressure plate 41. 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 the acceleration channel 50. There are multiple first grooves 411 on the pressure plate 41, and the multiple first grooves 411 are evenly distributed around the circumference of the pressure plate 41. The mixed flow channel 51 is constructed as an annular channel, and the cross section of the mixed flow channel 51 can be a circular ring. The mixed flow channel 51 surrounds the slideway 53 and surrounds the first reflux channel 40. The multiple first grooves 411 on the pressure plate 41 are all aligned with the entrance of the mixed flow channel 51.

[0035] In this way, the multiple acceleration channels 50 surrounding the pressure plate 41 can uniformly spray high-speed water flow to the inlet of the annular mixed flow channel 51 in the circumferential direction of the mixed flow channel 51, and then the outlet of the annular mixed flow channel 51 can uniformly output the water-gas mixed fluid, and a part of the water-gas mixed fluid will drive the dirt from the edge of the foaming net 2 to the dirt outlet 21 when it flows back to the first reflow channel 40, so that the dirt detached from various places of the foaming net 2 can be driven to the dirt outlet 21, and the dirt can be removed more thoroughly. At the same time, the cross-section of the acceleration channel 50 of this structure can be set larger, so that the acceleration channel 50 is less likely to be dirty and blocked. The cross-section of the acceleration channel 50 of this structure can also be set smaller, for example, the width and depth of the first groove 411 are both set to be less than 0.3 mm. Even if the cross-section of the acceleration channel 50 is set to be very small, since the acceleration member 4 can slide back and forth relative to the air intake frame 5 to remove the dirt and impurities in the acceleration channel 50, the acceleration channel 50 with a smaller cross-section will not be dirty and blocked.

[0036] In another exemplary embodiment, 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 configured as an annular channel with uniform width. The mixed flow channel 51 is configured as an annular channel, and the acceleration channel 50 is aligned with the entrance of the mixed flow channel 51. The mixed flow channel 51 surrounds the slideway 53 and surrounds the first return channel 40. In this embodiment, the mounting groove 54 is configured as a circular groove, the pressure plate 41 is configured as a disc, and the mounting groove 54, the pressure plate 41, the mixed flow channel 51, the slideway 53, and the dirt outlet 21 are coaxially arranged.

[0037] In this way, the acceleration channel 50 with an annular cross section can uniformly spray high-speed water flow to the inlet of the annular mixed flow channel 51 in the circumferential direction of the mixed flow channel 51, and then the outlet of the annular mixed flow channel 51 can uniformly output water-gas mixed fluid, and a part of the water-gas mixed fluid will drive the dirt from the edge of the foaming net 2 to the dirt outlet 21 when it flows back to the first reflow channel 40, so that the dirt detached from various places of the foaming net 2 can be driven to the dirt outlet 21, and the dirt can be removed more thoroughly. At the same time, the cross section of the acceleration channel 50 of this structure can be set larger, so that the acceleration channel 50 is not easy to be dirty and blocked. The cross section of the acceleration channel 50 of this structure can also be set smaller, for example, the width between the side of the pressure plate 41 and the side of the mounting groove 54 is set to be less than 0.3mm, even if the cross section of the acceleration channel 50 is set to be very small, because the acceleration member 4 can slide back and forth relative to the air intake frame 5 to remove the dirt and impurities in the acceleration channel 50, the acceleration channel 50 with a smaller cross section will not be dirty and blocked.

[0038] In an illustrative embodiment, a plurality of air intake holes 52 are provided on the air intake frame 5, and the plurality of air intake holes 52 are provided on the outside of the mixed flow channel 51 and are evenly arranged around the circumference of the mixed flow channel 51. A plurality of air intake grooves 1311 are provided on the outer peripheral wall of the connecting tube 131, and the plurality of air intake grooves 1311 are evenly arranged around the circumference of the connecting tube 131. The inner walls of the plurality of air intake grooves 1311 and the inner wall of the inner tube 12 enclose a plurality of air intake channels 105. A plurality of air inlet ports 103 are also provided on the shell 1, and one end of the plurality of air intake channels 105 is respectively connected to the plurality of air inlet ports 103, and the other end of the plurality of air intake channels 105 is respectively connected to the plurality of air intake holes 52. In this way, the plurality of air inlet ports 103 can evenly deliver airflow to the entrance of the mixed flow channel 51 through the plurality of air inlet channels 105 and the plurality of air intake holes 52.

[0039] In an illustrative embodiment, Figure 6 , 8 As shown, the support column 42 abuts against the edge of the dirt outlet 21 of the foaming net 2 , and a connecting groove 421 is provided at the end of the support column 42 abutting against the foaming net 2 , and the mixing chamber 104 is connected to the dirt outlet 21 through the connecting groove 421 .

[0040] In this way, the fluid and dirt in the mixing chamber 104 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, thereby preventing the support column 42 from blocking the dirt outlet 21.

[0041] In an illustrative embodiment, the accelerator 4 further includes a plurality of limiting ridges 43. The plurality of limiting ridges 43 are all disposed on the outer peripheral surface of the support column 42. The limiting ridges 43 may be straight bar-shaped protrusions. The limiting ridges 43 are parallel to the support column 42, and the plurality of limiting ridges 43 are all clearance-matched with the slideway 53. The plurality of limiting ridges 43 are evenly distributed along the circumference of the support column 42, and the first reflux channel 40 is formed between two adjacent limiting ridges 43.

[0042] By means of the clearance fit between the plurality of limiting ridges 43 and the slideway 53, a more stable sliding connection can be formed between the accelerator 4 and the air intake frame 5, and the accelerator 4 can slide more stably along the slideway 53 of the air intake frame 5. Meanwhile, the size of the first reflow channel 40 can also remain unchanged during the reciprocating sliding of the accelerator 4.

[0043] In an illustrative embodiment, Figure 4 , 6As shown, the bubbler 100 also includes a filter 6. The filter 6 is arranged between the accelerator 4 and the water inlet 101 of the shell 1 and between the air inlet frame 5 and the water inlet 101 of the shell 1. The filter 6 includes a base 61 and a filter portion 62. The base 61 is constructed in a circular ring shape, and the base 61 is fixed on the shell 1. The base 51 is provided with a water passage 611 whose end is connected to the water inlet 101. The filter portion 62 is constructed in a mesh structure, and the filter portion 62 covers one end of the water passage 611 of the base close to the water inlet 101 of the shell 1.

[0044] The air intake frame 5 further includes a water retaining ridge 45 , which is disposed on a plate surface of the pressure plate 41 facing the water passage 611 of the base 61 .

[0045] The pressure plate 41 of the acceleration member 4 covers the end of the water passage 611 of the base 61 facing away from the water inlet 101 of the shell 1 when not under water pressure, and the water retaining ridge 45 extends into the water passage 611 and along the end edge of the water passage 611.

[0046] In this way, the water flow input from the water inlet 101 is first filtered through the filter part 62 of the filter 6 to remove large particles of impurities, and the filtered water flow enters the water passage 611 of the base 61 to push the pressure plate 41 to move toward the bubble net 2, and a gap is generated between the pressure plate 41 and the base 61, and the water flow can continue to enter the acceleration channel 50 from the gap between the pressure plate 41 and the base 61. When the water pressure of the water inlet 101 is low, the water retaining ridge 45 can hold the water flow and increase the water pressure of the pressure plate 41, so that the water flow can push the pressure plate 41 to move toward the bubble net 2, which can avoid the water flow in the water passage 611 being difficult to push the bubble net 2 when the water pressure of the water inlet 101 is low, resulting in a small amount of water output from the bubbler 100.

[0047] In an illustrative embodiment, Figure 7 , 9 As shown, the water retaining rib 45 is constructed as an annular protrusion and is coaxial with the water passage 611 of the base 61. A plurality of notches 451 are provided on the water retaining rib 45, and the plurality of notches 451 may be evenly distributed in the circumferential direction of the water retaining rib 45.

[0048] The water flow in the water passage 611 of the base 61 can flow out of the water retaining ridge 45 from the notch 451 on the water retaining ridge 45 , thereby reducing the resistance of the water retaining ridge 45 to the water flow and increasing the water output of the bubbler 100 .

[0049] In an illustrative embodiment, Figure 7As shown, the outer cylinder 11 is provided with a first positioning shoulder 110 located on the side of the inner thread of the outer cylinder 11 close to the water inlet 101. The housing 1 also includes a sealing gasket 14. The sealing gasket 14 can be a circular ring 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.

[0050] In an illustrative embodiment, Figure 6 As shown, a second positioning shoulder 121 is provided on the inner wall of the inner tube 12 , and the outer edge portion of the air intake frame 5 and the outer edge portion of the surface cover 13 are clamped between the second positioning shoulder 121 and the sealing gasket 14 .

[0051] In this way, the outer edge portion of the air intake frame 5 and the outer edge portion of the surface cover 13 are clamped between the second positioning shoulder 121 and the sealing gasket 14, and the air intake frame 5 and the surface cover 13 can be firmly fixed in the installation cavity 104 and cannot move relative to the inner tube 12. This assembly method is simple and reliable.

[0052] The present application also proposes a water outlet device, which can be a faucet, a shower head, a shower head, or other device capable of discharging water outward. The water outlet device includes the bubbler 100 as described above. The water outlet device discharges water outward through the bubbler 100, thereby generating microbubbles in the water flow.
