A plurality of water through holes 52 are arranged on the side wall of the water passing cavity 51 along the circumferential direction. The bottom wall 512 of the water passing cavity is circumferentially provided with a plurality of convex columns 53 facing the water passing holes 52 at intervals. A first flange 54 is circumferentially arranged on the side wall of the water passing cavity 51 at the opening, and the upper surface of the first flange 54 is positioned on the first end surface 57. The edge of the first flange 54 is provided with a second annular wall 55 extending in a direction away from the bottom wall 512 of the water passing chamber.

The disc-shaped body 61 comprises a first blade 611, a fold 612 and a periphery 613, which are integral with each other. The first sheet body 611 is in a disc shape, a water through hole 64 communicated with the water passing cavity 51 and a first annular wall 62 extending along the direction departing from the water passing cavity bottom wall 512 are arranged in the middle of the first sheet body 611, and a bearing part is formed in the area, outside the first annular wall 62, of the first sheet body 611. The first annular wall 62 surrounds the water through holes 64, and a water passing channel 63 communicated with the water through holes 64 is formed in the first annular wall 62. The peripheral edge 613 is in the form of a ring that abuts the first end surface 57 of the water passing member 5. The bending portion 612 is located between the pressure-bearing portion and the peripheral edge 613 and extends along the circumferential direction, the bending portion 612 is fixedly connected to the peripheral edge 613 along the circumferential direction, and the bending portion 612 is bent along a direction away from the water cavity bottom wall 512 and connected to the pressure-bearing portion.
As shown in fig. 6, the filter 2 is an umbrella structure with an open end, and a plurality of filter holes 21 are distributed on the umbrella surface. The outer wall of the filter 2 at the opening end is provided with a second clamping ring 22 matched with the first clamping ring 56 in a clamping manner, and the filter 2 is matched with the water passing piece 5 in a clamping manner, so that the filter is convenient to disassemble and assemble.
As shown in fig. 7, the diffuser 3 is open at both ends, and includes a diffuser 3 body. The diffuser 3 body is a two-step stepped tubular structure. The diffuser 3 has a second chamber 31 and a third chamber 32 formed therein from top to bottom and communicating with each other. The second chamber 31 has an inner diameter larger than that of the third chamber 32, and a first step surface 33 facing upward is formed between the second chamber 31 and the third chamber 32. The lumen wall of the third lumen 32 is an inwardly tapered surface 321. The diffuser 3 body is provided with a third snap ring 34 on the outer wall of the third chamber 32, and a second flange extending outwards is provided on the side wall of the diffuser body close to the top opening of the second chamber 31 along the circumferential direction, and the second flange is used for being connected with the outside.
As shown in fig. 8 and 9, the bubbler body 4 is substantially of an open-topped cylindrical structure. A plurality of water outlet holes 41 are distributed on the bottom of the bubbler body 4, and a plurality of air inlets 42 are distributed on the side wall of the bubbler body 4 along the circumferential direction. A fourth snap ring 43 adapted to snap fit with the third snap ring 34 is provided on the inner wall of the bubbler body 4 near the open end.
The flow rate adjusting structure 1 of the present embodiment is installed: as shown in fig. 1 to 11, the diffuser 3 is first mounted on the bubbler body 4 with the third snap ring 34 and the fourth snap ring 43 snap-fitted. Next, the first flange 54 of the water passage member 5 is seated on the first step surface 33 of the diffuser 3. At this time, a part of the water passing cavity 51 extends out of the third cavity 32, and a water passing gap 72 communicated with the water passing hole 52 is formed between the conical surface 321 in the third cavity 32 and the outside of the water passing cavity 51; a cavity in the bubbler body 4 below the water passing gap 72 forms a gas-water mixing cavity 71; the air inlet 42 on the bubbler body 4 is positioned close to the water gap 72 and is communicated with the air-water mixing chamber 71. The peripheral edge 613 of the resilient member 6 is then placed against the first flange 54 of the water passage member 5 and shields the water passage chamber 51. Finally, the filter 2 is installed above the elastic member 6, and the bottom end of the filter 2 abuts against the periphery 613 of the elastic member 6, so that the second snap ring 22 is in snap fit with the first snap ring 56. The filter 2 and the elastic element 6 now enclose a first chamber.
The bubbler 7 of the present embodiment is, in use: as shown in fig. 1 to 13, the water flow enters the first chamber after being filtered by the filter 2. The water flow entering the first cavity has one part directly entering the water passing cavity 51 from the water passing channel 63, and the other part firstly impacts the pressure bearing part of the elastic part 6 and is stored to a certain height and then enters the water passing channel 63 to flow to the water passing cavity 51. Therefore, when water flow with different water pressures impacts the pressure-bearing part, the pressure-bearing part will elastically deform towards the bottom wall 512 of the water passing cavity to adjust the water passing area of the water passing cavity 51 internally connected with the water passage 63 and the water passing holes. Along with the increase of the water pressure, the elastic deformation of the pressure-bearing part is gradually increased, so that the water passing area of the water passing cavity 51 internally connected with the water passage 63 and the water passing holes 52 is automatically adjusted according to the water pressure, and the stability of the water outlet flow is realized. After the water flows to the water passing cavity 51, in the process of flowing to the water passing holes 52, part of water is scattered into thinner water flow through the convex columns 53 respectively and flows to the water passing gap 72 from the water passing holes 52; and the other part flows directly from the water through holes 52 to the water through gap 72. After flowing into the water gap 72, the water impacts the conical surface 321 in the third chamber 32, and the conical surface 321 further breaks up the water into thinner water and adjusts the flow direction of the water. Then, the water flows into the air-water mixing chamber 71. When water flows from the narrow area of the water passing gap 72 to the air-water mixing chamber 71 with a larger lower space, the flow rate is increased, so that a negative pressure state is formed in the air-water mixing chamber 71, and therefore, pressure difference exists between the air-water mixing chamber and the outside, air enters the air-water mixing chamber 71 from the air inlet 42 and is mixed with the water flow scattered by the conical surface 321, and bubble water is formed. The bubble water flows out of the bubbler 7 after being rectified by the water outlet holes 41. The flow regulating structure 1 in the bubbler 7 of the present embodiment has a simple structure and is easy to install, and compared with the O-ring in the prior art, the O-ring has a larger bearing area and is not easy to age, the elasticity is not easy to loosen, the hardness is easy to control, and the service life is longer. The first annular wall 62 is arranged in the flow regulating structure 1 in the bubbler 7, so that water flow can enter the water channel 63 after being stored to a certain height, and the pressure of the water flow impacting the bearing part is higher. The provision of the bent portion 612 can increase the space for elastic deformation of the elastic member 6; while effectively preventing the peripheral edge 613 of the elastic member 6 from being lifted when the pressure receiving portion is elastically deformed.
The description of the above specification and examples is intended to be illustrative of the scope of the present invention and is not intended to be limiting. Modifications, equivalents and other improvements which may occur to those skilled in the art and which may be made to the embodiments of the invention or portions thereof through a reasonable analysis, inference or limited experimentation, in light of the common general knowledge, the common general knowledge in the art and/or the prior art, are intended to be within the scope of the invention.
