Description

Technical Field

[0001] The invention relates to the field of water outlet devices, and in particular to a flow regulating structure and a bubbler. Background Art

[0002] In the water outlet device, in order to maintain the stability of the flow rate under different water pressure conditions, the flow rate under different water pressures is generally adjusted by setting a flow regulating structure.

[0003] In the prior art, most flow regulating structures are achieved by setting an annular water channel on the body of the flow regulating structure; an elastic O-ring is installed in the water channel, and a water gap is left between the O-ring and the water channel for water flow to pass through; the water flows through the filter and flows into the diverter from the water gap. Since the O-ring is elastic, the water gap gradually decreases as the water pressure increases, so that the water flow rate is large when the water pressure is low and small when the water pressure is high, so as to maintain the stability of the water flow rate under different water pressures. However, the O-ring has the disadvantages of easy aging, easy relaxation of elasticity, difficult control of hardness and hardness, and difficult installation, which seriously affects the stability and service life of the flow regulating structure during use. Summary of the invention

[0008] Solution three: Based on Solution one or Solution two, the disc-shaped body is further provided with a bending portion between the pressure-bearing portion and the periphery, and the bending portion is bent from the periphery in a direction away from the bottom wall of the water passage chamber and connected to the pressure-bearing portion.

[0009] Option 4: A bubbler, comprising a filter, a bubbler body and a flow regulating structure as described in any of the above options; the flow regulating structure is located in the bubbler body; the filter is located above the elastic member and presses against the elastic member; the filter and the elastic member enclose a first cavity.

[0010] Option 5: Based on Option 4, the water flow part is provided with a first flange; the upper surface of the first flange is located on the first end surface, the edge of the first flange is provided with a second annular wall extending in a direction away from the bottom wall of the water flow chamber, and a first clamping ring is protruding on the inner wall of the second annular wall; the filter is provided with a second clamping ring that is clamped with the first clamping ring.

[0011] Solution 6: Based on Solution 5, the filter is an umbrella-shaped structure with one end open, and a plurality of filter holes are arranged on the umbrella-shaped surface; the second retaining ring is arranged on the outer wall of the open end of the filter.

[0012] Solution seven: Based on solution four, a plurality of convex columns facing the water through holes are arranged at intervals along the circumferential direction on the bottom wall of the water through cavity, and the convex columns are configured to disperse part of the water flowing from the water through cavity to the water through holes.

[0013] Option 8: Based on Option 5, it also includes a diffuser; the diffuser is open at both ends and is provided with a second cavity and a third cavity that are interconnected, and a first upward step surface is formed between the second cavity and the third cavity; the diffuser is installed in the bubbler body, the first flange of the water flow member is located on the first step surface, and the water flow cavity extends out of the third cavity; a water flow gap that is connected to the water flow hole is formed between the inner cavity wall of the third cavity and the outer wall of the water flow cavity, and the inner cavity wall of the third cavity is a tapered surface that tapers inwardly, and the tapered surface is suitable for adjusting the flow direction of water flowing to the water flow gap and breaking up the water flow.

[0014] Option 9: Based on Option 8, the bubbler body is a cylindrical structure with an opening at the top; a plurality of air inlets are circumferentially arranged on the side wall of the bubbler body near the water gap, and the air inlets are configured to allow air to enter the bubbler body; a plurality of water outlet holes for water to flow out are arranged on the bottom wall of the water cavity of the bubbler body.

[0015] Solution 10: Based on Solution 9, a third clamping ring is provided on the outer wall of the diffuser; and a fourth clamping ring suitable for clamping with the third clamping ring is provided on the inner wall of the bubbler body.

[0016] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0017] Since the elastic part is elastic, when water flows with different water pressures impact the pressure-bearing part, the pressure-bearing part will elastically deform in the direction of the bottom wall of the water passage chamber. As the water pressure increases, the elastic deformation of the pressure-bearing part gradually increases, so that the water flow area connecting the water-passing hole and the water-passing hole in the water passage chamber is automatically adjusted according to the size of the water pressure, and the water flow rate is stabilized. Since the pressure-bearing area of ​​the disc-shaped body is large, compared with the O-ring in the prior art, it is not easy to age, the elasticity is not easy to relax, the hardness is easy to control, and the service life is increased; and the disc-shaped body is more convenient to install than the O-ring. The first ring wall is set, so that the water flow impacting the pressure-bearing part needs to be stored to a certain height before entering the water passage, which can make the water flow pressure impacting the pressure-bearing part greater, and the elastic deformation degree of the pressure-bearing part greater. The bending part is set to increase the elastic deformation space of the elastic part; at the same time, when the pressure-bearing part is elastically deformed, the peripheral edge of the elastic part is effectively prevented from tilting. After the water flow is filtered by the filter, it enters the first cavity and flows out from the water passage hole of the flow regulating structure. The bubbler adopts the above-mentioned flow regulating structure, so the bubbler has all the beneficial effects of the flow regulating structure. The filter is snap-fitted with the water passing part for easy disassembly and assembly. A convex column is set on the bottom wall of the water passing chamber of the water passing chamber. When the water flows from the water through hole into the water passing chamber and flows to the water passing hole, part of the water flow is broken up by the convex column to form a thinner water flow out of the water passing hole, thereby improving the air-water mixing degree of the bubbler. When the water flows from the water passing hole to the water passing gap, the water flow impacts the cone surface. The cone surface further breaks up the water flow into a thinner water flow and adjusts the flow direction of the water flow at the same time. When the water flows from the narrow space of the water passing gap to the larger space of the bubbler body located below the diffuser, the water flow velocity increases, so that a negative pressure state is formed in the bubbler body. Therefore, there is such a pressure difference with the outside world, and the outside air will enter the bubbler body from the air inlet and mix with the water flow broken up by the cone surface to form bubble water. The bubble water flows out of the bubbler after being rectified by each water outlet. 9. The diffuser and the bubbler body are snap-fitted for easy disassembly and assembly.

[0045] Figure 1 As shown, the bubbler 7 includes a flow regulating structure 1 , a filter 2 , a diffuser 3 and a bubbler body 4 .

[0046] like Figure 1 As shown, the flow regulating structure 1 includes a water passing member 5 and an elastic member 6. Figures 1 to 3As shown, the water passing member 5 includes a first body 58, and the top end of the first body 58 forms a first end face 57. A water passing cavity 51 with a top end opening at the first end face 57 is formed in the first body 58. A plurality of water passing holes 52 are circumferentially arranged on the side wall of the water passing cavity 51. A plurality of convex columns 53 facing the water passing holes 52 are circumferentially arranged on the bottom wall 512 of the water passing cavity. 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 located on the first end face 57. A second annular wall 55 extending in a direction away from the bottom wall 512 of the water passing cavity is arranged at the edge of the first flange 54. A first clamping ring 56 is convexly arranged on the inner wall of the second annular wall 55.

[0047] like Figure 4 and Figure 5 As shown, the elastic member 6 is provided with a disc-shaped body 61 and a first annular wall 62. The disc-shaped body 61 is located on the first end face 57 of the water passing member 5 and shields the water passing cavity 51. The disc-shaped body 61 includes a first sheet 611, a bending portion 612 and a peripheral edge 613 which are connected to each other as a whole. The first sheet 611 is in the shape of a disc, and a water hole 64 connected to the water cavity 51 and a first annular wall 62 extending in a direction away from the bottom wall 512 of the water passing cavity are provided in the middle position of the first sheet 611. The area of ​​the first sheet 611 located outside the first annular wall 62 forms a pressure-bearing portion. The first annular wall 62 is arranged outside the water hole 64, and a water passage 63 connected to the water hole 64 is formed inside the first annular wall 62. The peripheral edge 613 is an annular structure, which is attached to the first end face 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 in the circumferential direction. The bending portion 612 is fixedly connected to the peripheral edge 613 in the circumferential direction, and the bending portion 612 is bent in a direction away from the bottom wall 512 of the water passage chamber and connected to the pressure-bearing portion.

[0048] like Figure 6 As shown, the filter 2 is an umbrella-shaped structure with one end open, and its umbrella-shaped surface is provided with a plurality of filter holes 21. A second clamping ring 22 is provided on the outer wall of the filter 2 at the open end to engage with the first clamping ring 56, and the filter 2 engages with the water passing part 5 to facilitate disassembly and assembly.

[0049] like Figure 7 As shown, 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. A second cavity 31 and a third cavity 32 are formed in the diffuser 3 body from top to bottom, which are interconnected. The inner diameter of the second cavity 31 is larger than the inner diameter of the third cavity 32, and a first step surface 33 facing upward is formed between the second cavity 31 and the third cavity 32. The inner cavity wall of the third cavity 32 is a tapered surface 321 that tapers inwardly. The diffuser 3 body is provided with a third retaining ring 34 on the outer wall of the third cavity 32, and a second flange extending outward is provided circumferentially on the side wall close to the top opening of the second cavity 31, and the second flange is used to connect with the outside world.

[0050] like Figure 8 and Fig. 9 As shown, the bubbler body 4 is generally a cylindrical structure with an open top. A plurality of water outlet holes 41 are arranged on the bottom of the bubbler body 4, and a plurality of air inlets 42 are arranged along the circumferential direction on the side wall of the bubbler body 4. A fourth clamping ring 43 suitable for clamping with the third clamping ring 34 is arranged on the inner wall of the bubbler body 4 near the open end.

[0051] When installing the flow regulating structure 1 of this embodiment: Figures 1 to 11 As shown, first, the diffuser 3 is installed on the bubbler body 4, so that the third clamping ring 34 and the fourth clamping ring 43 are engaged. Next, the first flange 54 of the water passing member 5 is placed 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 connected to the water hole 52 is formed between the conical surface 321 in the third cavity 32 and the outside of the water passing cavity 51; the cavity below the water passing gap 72 in the bubbler body 4 forms an air-water mixing cavity 71; the air inlet 42 on the bubbler body 4 is located near the water passing gap 72 and communicates with the air-water mixing cavity 71. Afterwards, the periphery 613 of the elastic member 6 is placed against the first flange 54 of the water passing member 5, and the water passing cavity 51 is covered. Finally, the filter 2 is installed above the elastic member 6, and the bottom end of the filter 2 presses against the periphery 613 of the elastic member 6, and the second clamping ring 22 and the first clamping ring 56 are engaged. At this time, the filter 2 and the elastic member 6 enclose and form a first cavity.

[0052] When the bubbler 7 of this embodiment is used: Figures 1 to 13As shown, after the water is filtered by the filter 2, it enters the first chamber. A part of the water entering the first chamber directly enters the water chamber 51 from the water channel 63, and the other part first impacts the pressure-bearing part of the elastic member 6, and then enters the water channel 63 and flows to the water chamber 51 after being retained to a certain height. Therefore, when water with different water pressures impacts the pressure-bearing part, the pressure-bearing part will elastically deform in the direction of the bottom wall 512 of the water chamber to adjust the water flow area connecting the water hole 64 and the water hole in the water chamber 51. As the water pressure increases, the elastic deformation of the pressure-bearing part gradually increases, so as to automatically adjust the water flow area connecting the water hole 64 and the water hole 52 in the water chamber 51 according to the water pressure, thereby achieving the stability of the water flow rate. After the water flows to the water passage chamber 51, in the process of flowing to the water passage hole 52, a part of the water is broken up into a thinner water flow by each convex column 53, and flows from the water passage hole 52 to the water passage gap 72; the other part flows directly from the water passage hole 52 to the water passage gap 72. After the water flows to the water passage gap 72, it impacts the cone surface 321 in the third chamber 32, and the cone surface 321 further breaks up the water flow into a thinner water flow and adjusts the flow direction of the water flow. After that, the water flows into the air-water mixing chamber 71. When the water flows from the narrow area of ​​the water passage gap 72 to the air-water mixing chamber 71 with a larger space below, the flow rate increases, so that a negative pressure state is formed in the air-water mixing chamber 71, so there is a pressure difference with the outside world, and the gas will enter the air-water mixing chamber 71 from the air inlet 42 and mix with the water flow broken up by the cone surface 321 to form bubble water. The bubble water flows out of the bubbler 7 after being rectified by each water outlet hole 41. The flow regulating structure 1 in the bubbler 7 of this embodiment has a simple structure and is easy to install. Compared with the O-ring in the prior art, it has a larger pressure-bearing area, is not easy to age, is not easy to relax in elasticity, is easy to control in hardness and softness, and has a longer service life. A first annular wall 62 is provided in the flow regulating structure 1 in the bubbler 7, so that the water flow needs to be retained to a certain height before entering the water channel 63, which can increase the pressure of the water flow impacting the pressure-bearing part. The bending part 612 is provided to increase the space for the elastic deformation of the elastic part 6; at the same time, when the pressure-bearing part is elastically deformed, the peripheral edge 613 of the elastic part 6 is effectively prevented from warping.

[0053] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
