[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0032] Please see attached Figure 3 To Attachment Fig. 9 The structure diagram of the liquid supply module 100, the foam generating device 200 and the liquid outlet device 300 of the embodiment of the present application is shown. Figure 1 The working process of the foam generating device of the prior art is as follows: Figure 2FIG. 2 is a working flow of the foam generating device 200 according to an embodiment of the present application. Figure 1 As shown, in the foam generating device of the prior art, a self-priming liquid adding module is provided in the main body, which sucks the foaming liquid in the foaming liquid storage module into the main body, and a water supply module is directly connected to an inlet of the main body. The pressure and flow rate of the water flow delivered to the main body by the water supply module are unstable. Therefore, when the water with unstable pressure and flow rate is mixed with the foaming liquid, the mixed liquid formed is fluctuating and unstable, resulting in a large difference in the foaming effect of the foam generating device, and the number of foaming times is difficult to guarantee. Figure 2 The working process of the foam generating device of the present application is shown. The present application adds a pressure and flow stabilizing module between the self-priming liquid adding module and the water supply module.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, the embodiment of the present application provides a liquid supply module 100, including a body 1 and a pressure stabilizing and flow stabilizing module 2. The body 1 is provided with a liquid supply channel 11. The pressure stabilizing and flow stabilizing module 2 is mounted to the body 1 and is located on the upstream side of the liquid supply channel 11. The pressure stabilizing and flow stabilizing module 2 is provided with a pressure stabilizing portion 21 and a flow stabilizing portion 22. The pressure stabilizing portion 21 is configured to stabilize the pressure of the liquid entering the liquid supply channel 11, and the flow stabilizing portion 22 is configured to stabilize the flow of the liquid passing through the liquid supply channel 11.

[0034] Specifically, the liquid supply module 100 of the embodiment of the present application is provided with a pressure-stabilizing and flow-stabilizing module 2 on the upstream side of the liquid supply channel 11 of the main body 1. The pressure-stabilizing part 21 is provided to stabilize the pressure of the liquid entering the liquid supply channel 11, and the flow-stabilizing part 22 is provided to stabilize the flow of the liquid passing through the liquid supply channel 11, so that the pressure and flow of the water flow after passing through the liquid supply channel 11 through the pressure-stabilizing and flow-stabilizing module 2 are kept stable. If the liquid supply module 100 of the present application provides water flow for the foam generating device 200, when the water flow with stable pressure and flow in the main body 1 is mixed with the foaming liquid, the generated foam has a stable generation effect and the number of foaming times is long-lasting and stable.

[0035] It can be understood that the liquid supply module 100 of the present application can provide a water flow with a stable pressure and flow rate for the foam generating device 200, and the liquid supply module 100 of the present application can also be used to provide a water flow with a stable pressure and flow rate for devices with other functional structures.

[0036] The pressure stabilizing part 21 of the present application can be configured to include a spring or other deformable components, so that the pressure of the liquid entering the liquid supply channel 11 can be buffered by the deformation of the deformable components, and the flow stabilizing part 22 can be configured to be able to adaptively change the cross-sectional area of ​​a certain section of the flow channel of the liquid flowing through the inner cavity of the body 1, thereby stabilizing the flow of the liquid passing through the liquid supply channel 11. Specifically, when the flow of the liquid entering the body 1 increases, the flow stabilizing part 22 can correspondingly reduce the flow of the liquid flowing out of the body 1; when the flow of the liquid entering the body 1 decreases, the flow stabilizing part 22 can correspondingly increase the flow of the liquid flowing out of the body 1, thereby achieving the purpose of enabling the flow stabilizing part 22 to stabilize the flow of the liquid passing through the liquid supply channel 11.

[0037] In an exemplary embodiment, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the voltage and current stabilizing module 2 includes a pressure regulating component 23, which includes a liquid passing portion 231 and a deformable portion 232. The liquid passing portion 231 is connected to the liquid supply channel 11, and the deformable portion 232 is arranged on the radial outside of the liquid passing portion 231 and is connected to the liquid passing portion 231.

[0038] The pressure stabilizing portion 21 includes a deformable portion 232 , which is configured to be able to elastically deform under the impact of the liquid flowing toward the pressure regulating member 23 to buffer the pressure of the liquid, thereby stabilizing the pressure of the liquid entering the liquid supply channel 11 .

[0039] Specifically, the deformable portion 232 of the embodiment of the present application is configured to be able to elastically deform under the impact of the liquid flowing to the pressure regulating member 23 to buffer the pressure of the liquid, thereby achieving the purpose of stabilizing the pressure of the liquid entering the liquid supply channel 11. In this way, by appropriately selecting the material of the deformable portion 232, only one deformable portion 232 is used to stabilize the pressure of the liquid. The structural design is simple and easy to process and assemble. The liquid-passing portion 231 is connected to the liquid supply channel 11 so that the liquid can flow smoothly inside the body 1. The liquid-passing portion 231 is connected to the deformable portion 232, so that the liquid-passing portion 231 can also change in displacement as the deformable portion 232 changes in deformation and displacement.

[0040] In an exemplary embodiment, Figure 3 , Figure 4 and Figure 6 As shown, the liquid-passing portion 231 is configured as a barrel-shaped structure, and the deformable portion 232 is disposed outside the inlet 233 of the liquid-passing portion 231 .

[0041] The deformable portion 232 is provided with at least one first annular groove 2321 and at least one second annular groove 2322 . The notches of the first annular groove 2321 and the second annular groove 2322 are arranged opposite to each other. The first annular groove 2321 and the second annular groove 2322 are staggeredly distributed along the radial direction of the liquid passing portion 231 .

[0042] Specifically, the deformable part 232 is provided with at least one first annular groove 2321 and at least one second annular groove 2322, and the first annular groove 2321 and the second annular groove 2322 are arranged in a staggered manner and the notches are arranged opposite to each other, so that when water flows into the body 1 and impacts the pressure regulating member 23, the water flows can enter at least one annularly distributed notch, so that the deformable part 232 is deformed to buffer the pressure of the water flow. The structure of the first annular groove 2321 and the second annular groove 2322 with the notches arranged opposite to each other increases the deformation amount of the deformable part 232 of the present application, so that the ability of the deformable part 232 of the present application to buffer the water flow pressure is enhanced.

[0043] The liquid passing portion 231 is set as a barrel-shaped structure, which has a simple design, is convenient for water to flow through, and is also convenient for sleeve-arranging the first annular groove 2321 and the second annular groove 2322 on the radial outer side of the barrel-shaped structure. The deformable portion 232 of the present application may be provided with only one first annular groove 2321 and one second annular groove 2322, or the deformable portion 232 of the present application may be provided with multiple first annular grooves 2321 and multiple second annular grooves 2322, all of which are within the protection scope of the present application.

[0044] In an exemplary embodiment, Figure 4 and Figure 6 As shown, along the radial direction of the deformable portion 232 from inside to outside, the distance between the bottom wall of the first annular groove 2321 and the outlet 12 of the body 1 tends to decrease, and the distance between the bottom wall of the second annular groove 2322 and the outlet 12 of the body 1 tends to decrease.

[0045] Specifically, when the deformable portion 232 is provided with a first annular groove 2321 and a second annular groove 2322, the distance between the bottom walls of the first annular groove 2321 and the second annular groove 2322 and the outlet 12 of the main body 1 gradually decreases from the inside to the outside along the radial direction of the deformable portion 232, so that the liquid passing portion 231 located in the middle of the deformable portion 232 protrudes toward the upstream side of the liquid supply channel 11, so that when the water flow hits the deformable portion 232, the deformable portion 232 can carry and accommodate more water, the deformable portion 232 has a stronger ability to buffer the water flow pressure, and the deformable portion 232 has a stronger ability to stabilize the liquid pressure entering the liquid supply channel 11.

[0046] like Figure 4In the illustrated embodiment, when the deformable portion 232 is provided with a plurality of first annular grooves 2321 and a plurality of second annular grooves 2322, along the radial direction of the deformable portion 232 from the inside to the outside, the distance between the bottom wall of the plurality of first annular grooves 2321 and the outlet 12 of the main body 1 gradually decreases, and the distance between the bottom wall of the plurality of second annular grooves 2322 and the outlet 12 of the main body 1 gradually decreases, thereby the liquid passing portion 231 located in the middle of the deformable portion 232 protrudes toward the upstream side of the liquid supply channel 11, so that when the water flow impacts the deformable portion 232, the deformable portion 232 can carry and accommodate more water, and the deformable portion 232 has a stronger ability to stabilize the liquid pressure entering the liquid supply channel 11.

[0047] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the main body 1 is provided with an installation cavity 13 with an opening at one end, and the pressure regulating component 23 is installed in the installation cavity 13. The pressure and flow stabilizing module 2 also includes a liquid inlet shell component 24 provided with a fluid channel 241. The liquid inlet shell component 24 is connected to the main body 1 and covers the open end of the installation cavity 13. One end of the liquid inlet shell component 24 is inserted into the installation cavity 13 and abuts against the radial outer end of the deformable portion 232, so that the liquid inlet shell component 24 and the pressure regulating component 23 enclose a pressure stabilizing cavity 25 connected to the fluid channel 241 and the liquid passing portion 231. The pressure stabilizing portion 21 also includes the pressure stabilizing cavity 25 and the liquid inlet shell component 24.

[0048] Specifically, the liquid inlet housing 24 and the pressure regulating member 23 enclose a pressure stabilizing chamber 25, and the liquid enters the body 1 from the fluid channel 241, and impacts the pressure regulating member 23 at the position of the pressure stabilizing chamber 25, and the deformable portion 232 of the pressure regulating member 23 is elastically deformed, which plays a role in buffering the water flow and stabilizing the water pressure. When the water pressure of the water flow entering the pressure stabilizing chamber 25 decreases, the deformable portion 232 is deformed and deflected to the side of the liquid inlet housing 24, and when the water pressure of the water flow entering the pressure stabilizing chamber 25 increases, the deformable portion 232 is deformed and deflected to the side of the outlet 12 of the body 1.

[0049] It can be understood that the liquid inlet housing 24 and the body 1 can be designed as an integrated unit, and can also form a fluid channel 241 and a pressure stabilizing chamber 25. In the embodiment of the present application, the liquid inlet housing 24 and the body 1 are designed as separate units, which makes it easier to install the pressure and flow stabilizing module 2 into the inner cavity of the body 1, and also facilitates the installation and fixation of the deformable portion 232.

[0050] In an exemplary embodiment, Figure 3 , Figure 4 and Figure 5As shown, the voltage and flow stabilizing module 2 also includes a flow member 26 and an elastic member 27, and the two ends of the elastic member 27 are respectively against the pressure regulating member 23 and the flow member 26; the liquid passing portion 231 and the flow member 26 enclose a flow gap 28 connected to the liquid supply channel 11; the elastic member 27 is configured to cooperate with the liquid in the body 1 to jointly adjust the size of the flow gap 28 to stabilize the liquid flow through the liquid supply channel 11; the flow stabilizing portion 22 includes the liquid passing portion 231, the elastic member 27 and the flow member 26.

[0051] Specifically, the two ends of the elastic member 27 are respectively arranged to abut against the pressure regulating member 23 and the flow member 26, and the liquid passing portion 231 and the flow member 26 enclose a flow gap 28 connected to the liquid supply channel 11. In this way, when the water flow impacts the deformable portion 232 to cause deformation and displacement change, the liquid passing portion 231 connected to the deformable portion 232 also shifts and changes along the direction of the water flow, so that the size of the flow gap 28 changes. At the same time, the pressure regulating member 23 can drive the elastic member 27 to deform together, and the deformed elastic member 27 will also affect the size of the flow gap 28. In this way, the elastic member 27 and the liquid entering the main body 1 can cooperate to adjust the size of the flow gap 28, and the purpose of stabilizing the water flow through the inner cavity of the main body 1 is achieved by adjusting the flow gap 28. When the water flow entering the main body 1 increases, the size of the flow gap 28 can be reduced accordingly; when the water flow entering the main body 1 decreases, the size of the flow gap 28 can be increased accordingly; when the water flow entering the main body 1 remains unchanged, the size of the flow gap 28 and the elastic member 27 do not change, thereby stabilizing the liquid flow through the liquid supply channel 11.

[0052] The two ends of the elastic member 27 are respectively against the pressure regulating member 23 and the flow member 26. The elastic deformation of the elastic member 27 cooperates with the water flow so that the flow gap 28 between the pressure regulating member 23 and the flow member 26 can be adaptively adjusted as the water flow changes. If the liquid supply module 100 of the present application is not provided with the elastic member 27, the pressure regulating member 23 will be impacted by the water flow and fit together with the flow member 26, so that the flow gap 28 and the water flow through the inner cavity of the body 1 cannot be adjusted. Figure 4 In the figure, along the axial direction of the flow member 26, the size of the flow gap 28 is marked with ΔL.

[0053] It can be understood that the liquid supply module 100 of the present application can be configured such that the flow member 26 is sleeved on the outside of the liquid passing portion 231, or the liquid passing portion 231 is sleeved on the outside of the flow member 26, both of which can enclose the flow gap 28. The elastic member 27 can be configured to abut against the deformable portion 232 and the flow member 26, or the elastic member 27 can be configured to abut against the liquid passing portion 231 and the flow member 26, both of which can achieve the purpose of the elastic member 27 affecting the size of the flow gap 28.

[0054] In an exemplary embodiment, Figure 4 and Figure 7 As shown, the flow member 26 is provided with a first flow channel 261 and a second flow channel 262 which are connected to each other. The inner diameter of the second flow channel 262 is smaller than the inner diameter of the first flow channel 261 . A turning surface 263 is provided between the first flow channel 261 and the second flow channel 262 .

[0055] A portion of the liquid passing portion 231 is inserted into the first flow channel 261, and the outer diameter of the liquid passing portion 231 is larger than the inner diameter of the second flow channel 262; the flow gap 28 is located between one end of the liquid passing portion 231 close to the second flow channel 262 and the turning surface 263; the liquid passing portion 231 is provided with a liquid outlet 2311, and the liquid outlet 2311 is configured to be able to communicate with the second flow channel 262 through the flow gap 28.

[0056] Specifically, a portion of the liquid passing portion 231 is inserted into the first flow channel 261, and the outer diameter of the liquid passing portion 231 is larger than the inner diameter of the second flow channel 262, so that the first flow channel 261 has a limiting effect on the liquid passing portion 231, preventing the liquid passing portion 231 from deflecting and swaying when the deformable portion 232 is displaced along the water flow direction. When the liquid passing portion 231 is set as a barrel structure, a portion of the liquid passing portion 231 is inserted into the first flow channel 261 of the flow passing member 26, and the flow gap 28 is set to be located between one end of the liquid passing portion 231 close to the second flow channel 262 and the turning surface 263. The structure is simple in design and easy to install and maintain.

[0057] The liquid outlet 2311 on the liquid passing portion 231 is configured to be connected to the second flow channel 262 through the flow gap 28, so that the size of the flow gap 28 can be changed to change the liquid flow rate flowing from the liquid passing portion 231 into the second flow channel 262.

[0058] In an exemplary embodiment, the liquid outlet 2311 is disposed on a side wall of the liquid passing portion 231 ; or the liquid outlet 2311 is disposed on a bottom wall of the liquid passing portion 231 close to an edge.

[0059] Specifically, Figure 3 , Figure 4 and Figure 6 In the illustrated embodiment, the liquid outlet 2311 is disposed on the side wall of the liquid passing portion 231, so that after the water flows into the liquid passing portion 231, it flows out from the liquid outlet 2311, then passes through the flow gap 28, and finally enters the second flow channel 262. In some embodiments, the liquid outlet 2311 is located near the edge of the bottom wall of the liquid passing portion 231, and after the water flows into the liquid passing portion 231, it also flows out from the liquid outlet 2311 first, and then flows through the flow gap 28. Changing the size of the flow gap 28 can affect the liquid flow rate entering the second flow channel 262.

[0060] The liquid outlet 2311 may be configured as a through hole with a circular cross section, or may be configured as a through hole with a cross section of other shapes, all of which are within the protection scope of the present application.

[0061] In an exemplary embodiment, Figure 7 As shown, the side wall of the first flow channel 261 is provided with a plurality of spaced guide ribs 2611 , which extend along the length direction of the first flow channel 261 and are configured to guide the liquid passing portion 231 to move along the length direction of the first flow channel 261 .

[0062] A liquid passage groove 2612 is formed between adjacent guide ribs 2611 , and the liquid passage groove 2612 is communicated with the liquid outlet 2311 and the flow gap 28 .

[0063] Specifically, a plurality of guide ribs 2611 are arranged at intervals on the side wall of the first flow channel 261. The guide ribs 2611 have a guiding function and can guide the liquid passing portion 231 to move along the length direction of the first flow channel 261 to prevent the liquid passing portion 231 from being skewed and swayed when the deformable portion 232 is displaced and deformed along the water flow direction.

[0064] When the liquid flows out from the liquid outlet 2311 of the liquid passing portion 231 , it can flow along the liquid passing groove 2612 and flow to the flow gap 28 . The liquid passing groove 2612 guides the liquid flowing into the first flow channel 261 , thereby accelerating the flow speed of the liquid inside the main body 1 .

[0065] In an exemplary embodiment, Figure 4 and Figure 7 As shown, an annular protrusion 264 is provided on one end of the liquid passing portion 231 close to the second flow channel 262 and / or the turning surface 263 . The annular protrusion 264 is provided with an anti-blocking notch 2641 . The anti-blocking notch 2641 connects the liquid outlet 2311 and the second flow channel 262 .

[0066] Specifically, if the water pressure flowing into the body 1 is relatively high or the water inlet flow rate is relatively high, although there is an elastic member 27 supporting the pressure regulating member 23 and the flow-through member 26, the water flow may still cause the liquid-through portion 231 and the flow-through member 26 to fit together, thereby causing the liquid supply channel 11 to be cut off. If an anti-blocking notch 2641 is provided on the annular protrusion 264, the water flow can pass through the anti-blocking notch 2641 and enter the second flow channel 262, thereby preventing the liquid supply module 100 from being cut off in special circumstances such as high water inlet pressure and high water inlet flow rate.

[0067] The anti-blocking notch 2641 can be disposed at one end of the liquid passing portion 231 close to the second flow channel 262 , or can be disposed on the folding surface 263 , both of which are within the protection scope of the present application.

[0068] In an exemplary embodiment, Figure 3 and Figure 4 As shown, a protrusion 265 and a step surface 266 are provided at one end of the flow-through member 26 close to the pressure regulating member 23, and the protrusion 265 and the step surface 266 are connected; one end of the elastic member 27 abuts against the deformable portion 232, and the other end of the elastic member 27 is sleeved on the outside of the protrusion 265 and abuts against the step surface 266.

[0069] Specifically, Figure 3 and Figure 4 As shown, one end of the elastic member 27 can abut against the inner wall of the annular groove of the deformable portion 232. The other end of the elastic member 27 is sleeved on the outside of the protrusion 265, rather than arranging the elastic member 27 inside the flow-through member 26, so that the spring member 27 can avoid occupying the space of the liquid supply channel 11 in the body 1.

[0070] The working process of the liquid supply module 100 of an embodiment of the present application is as follows: water flows into the pressure stabilizing chamber 25 from the fluid channel 241, and a part of the water flows impacts the first annular groove 2321 and the second annular groove 2322 of the deformable part 232, so that the deformable part 232 is deformed to buffer the water flow pressure. The deformable part 232 is deformed, thereby driving the liquid passing part 231 to change its displacement along the axial direction of the liquid passing part 231, so that the size ΔL of the flow gap 28 changes, and the deformation of the deformable part 232 also causes the elastic part 27 to deform. Another part of the water flows into the pressure stabilizing chamber 25 and enters the inner cavity of the liquid passing part 231, and then flows to the liquid passing groove 2612 through the liquid outlet 2311, and flows through the flow gap 28 into the second flow channel 262. Among them, when the pressure and flow of the liquid entering the pressure-stabilizing chamber 25 increase, the deformable portion 232 will deform to buffer the pressure of the liquid, and the deformable portion 232 will deform to be biased toward the outlet 12 side of the main body 1. At this time, ΔL decreases to reduce the liquid flow through the flow gap 28; when the pressure and flow of the liquid entering the pressure-stabilizing chamber 25 decrease, the deformable portion 232 will deform to buffer the pressure of the liquid, and the deformable portion 232 will deform to be biased toward the fluid channel 241. At this time, ΔL increases to increase the liquid flow through the flow gap 28, thereby achieving the purpose of stabilizing the flow of liquid through the liquid supply channel 11.
