[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] As one embodiment of the present invention, such as Figures 1 to 9 As shown, the hydraulic foaming valve device of the present invention includes a base structure having a fluid flow channel; the base structure is configured with a liquid storage chamber 501 for containing foaming liquid, the liquid storage chamber 501 is adapted to a driving component that is hydraulically driven to discharge the foaming liquid in the liquid storage chamber 501; the base structure is also provided with a fluid input structure connected to an external water supply pipeline, and a foaming functional structure for realizing gas-liquid mixing foaming; the foaming liquid discharged from the liquid storage chamber 501 can merge with the water flow introduced by the fluid input structure, and then form foam output through the foaming functional structure;

[0034] The base structure includes a valve seat 1, a fluid input structure connected to one side of the valve seat 1, and a valve cover 3 connected to the top of the valve seat 1. The fluid input structure is a water inlet pipe 2, which communicates with the interior of the valve cover 3. The liquid storage chamber 501 is disposed inside the valve cover 3. The valve seat 1 has a first liquid inlet hole 103 corresponding to the liquid storage chamber 501 and a first water inlet channel 102 communicating with the interior of the valve cover 3. The bottom of the valve seat 1 is provided with a water outlet panel 8, and the foaming functional structure is a foaming component 9 installed in the middle of the water outlet panel 8.

[0035] In use, connect the water inlet pipe 2 to the external water supply pipeline, ensuring that the pipeline is connected and leak-free, and at the same time ensure that the water inlet pipe 2 and the internal channel of the valve cover 3 are smoothly connected; turn on the external water supply switch, and the water flows through the water inlet pipe 2 into the valve cover 3, and then flows through the first water inlet port 102 of the valve seat 1 to the side of the water outlet panel 8; the water flows into the foaming component 9 under pressure, and at the same time, the liquid storage chamber 501 is squeezed out by the water inlet pressure and mixes with the water flow. Finally, the water flow is processed by the foaming component 9 to form foam and spray out; if you need to stop using it, just turn off the external water supply switch. The piston push plate 504 stops after the hydraulic pressure disappears, and the device stops discharging liquid.

[0036] To ensure the usability of the liquid storage chamber 501, in one embodiment of the present invention, the liquid storage chamber 501 is located inside the liquid storage cylinder 5, and a liquid outlet seat 502 is installed at the bottom of the liquid storage chamber 501. The liquid outlet seat 502 has a liquid outlet channel 503 communicating with the first liquid inlet hole 103. The driving component is a piston push plate 504 that is sealed and slidably connected to the top of the inner side of the liquid storage chamber 501. The top of the liquid storage cylinder 5 is connected to the liquid inlet channel 505.

[0037] In use, place the liquid storage cylinder 5 onto the valve seat 1, ensuring that the liquid outlet channel 503 is connected to the first liquid inlet 103. Then install the valve cover 3, using the connection between the valve cover 3 and the valve seat 1 to hold the liquid storage cylinder 5 in place and prevent it from detaching from the valve seat 1. Connect the water inlet pipe 2 to the external water supply pipeline, ensuring the pipeline is connected and leak-free, and ensuring that the water inlet pipe 2 and the internal channel of the valve cover 3 are smoothly connected. Turn on the external water supply switch, and the water flows through the water inlet pipe 2 into the valve cover 3, and then flows through the first water inlet 102 of the valve seat 1 to the side of the water outlet panel 8. Under pressure, the water flows into the foaming component 9, and at the same time, the piston push plate 504 in the liquid storage chamber 501 is hydraulically driven to seal the sliding surface. When the foaming liquid flows out through the outlet channel 503 on the outlet seat 502, it mixes with the water discharged from the first water inlet 102. Finally, the water flows through the foaming component 9 and forms foam that is sprayed out. If it is necessary to stop using the device, simply turn off the external water supply switch. The piston push plate 504 stops after the hydraulic pressure is released, and the device stops discharging liquid. If it is necessary to adjust the liquid flow rate and foam concentration, the liquid volume entering the liquid storage chamber 501 can be changed by adjusting the opening and closing degree of the inlet channel 505 at the top of the liquid storage cylinder 5. The liquid pressure can then be adjusted by the sliding stroke of the piston push plate 504 to achieve precise control of the flow rate and foam state. The liquid pressure can also be adjusted by selecting different sizes of outlet channels 503.

[0038] The present invention achieves stable transmission of hydraulic drive through the sealed sliding cooperation between the liquid storage chamber 501 and the piston push plate 504, effectively avoiding fluctuations in liquid outlet pressure; when water flows through the foaming component 9, it can fully mix with air, forming a uniform and delicate foam that meets the usage requirements of cleaning, spraying and other scenarios.

[0039] To facilitate control of the foaming process, in one embodiment of the present invention, the bottom of the valve seat 1 is integrally formed with an elliptical positioning frame 104. A positioning plate 6 is provided at the bottom of the valve seat 1, and an inner positioning frame 601 is integrally connected to the upper surface of the middle part of the positioning plate 6. The inner positioning frame 601 is snapped into the inner side of the positioning frame 104. The first liquid inlet hole 103 is located inside the positioning frame 104, and the first water inlet port 102 is located at the inner edge of the positioning frame 104. A first water outlet port 602 penetrating the positioning plate 6 is provided inside the inner positioning frame 601. The bottom of the valve seat 1... A switching valve core 7 is rotatably connected. A grid-shaped sealing gasket 701 is embedded in the top of the switching valve core 7. An emulsification chamber 702 corresponding to the foaming component 9 is provided in the middle of the bottom of the switching valve core 7. A first regulating flow channel 704 communicating with the emulsification chamber 702 is opened on the switching valve core 7. After the switching valve core 7 is rotated, the first water outlet port 602 corresponds to the first regulating flow channel 704. A positioning sleeve 801 is integrally connected to the middle of the water outlet panel 8. The positioning sleeve 801 is located in the emulsification chamber 702, and the foaming component 9 is installed in the positioning sleeve 801.

[0040] In use, the inner positioning frame 601 is snapped into place along the positioning frame 104, utilizing the shape compatibility between the positioning frame 104 and the inner positioning frame 601 to achieve precise positioning, ensuring that the first liquid inlet hole 103 and the first water inlet channel 102 are unobstructed and the fluid passage is smooth; the grid-shaped sealing gasket 701 is embedded in the top of the switching valve core 7, ensuring that the grid-shaped sealing gasket 701 and the surface of the switching valve core 7 are flush; the switching valve core 7 is rotatably connected to the bottom of the valve seat 1, enabling switching... The grid-shaped sealing gasket 701 at the top of the valve core 7 is in close contact with the bottom contact surface of the valve seat 1, while ensuring that the emulsification chamber 702 at the bottom of the switching valve core 7 is aligned with the positioning sleeve 801 of the water outlet panel 8; the assembled foaming component 9 is aligned with the positioning sleeve 801, and the emulsification chamber 702 is inserted into the inner side of the positioning sleeve 801. The external thread section of the foamer base 905 is screwed and fixed to the internal thread structure of the positioning sleeve 801 to ensure that the foaming component 9 and the emulsification chamber 702 are coaxial and without any offset or loosening;

[0041] After rotating the switching valve core 7, the first regulating flow channel 704 on the valve core is aligned with the first water outlet 602. At this time, the grid-shaped sealing gasket 701 can prevent water from leaking into other areas. Water flows through the first regulating flow channel 704 into the emulsification chamber 702, where it works with the foaming component 9 to complete gas-liquid mixing and foam generation. The first liquid inlet 103 simultaneously supplies liquid to the liquid storage chamber 501. The pressure is adjusted by the piston push plate 504 to ensure stable foam output. Rotating the switching valve core 7 in the opposite direction, the first regulating flow channel 704 is offset from the first water outlet 602. The grid-shaped sealing gasket 701 remains sealed as the valve core rotates, preventing water from entering the emulsification chamber 702. It should be noted that a sealing ring is provided between the water outlet panel 8 and the switching valve core 7 to ensure sealing.

[0042] To achieve the switching between foaming and water output functions, as an embodiment of the present invention, the outer side of the positioning frame 104 is provided with several sets of second water inlet ports 105 opened on the valve seat 1, the outer side of the inner positioning frame 601 is provided with a second water outlet port 603 opened on the positioning plate 6, the bottom outer ring of the switching valve core 7 is provided with a water outlet chamber 703, and the outer ring of the switching valve core 7 is provided with a second regulating flow channel 705 communicating with the water outlet chamber 703; before the switching valve core 7 rotates, the second water outlet port 603 corresponds to the second regulating flow channel 705; the outer ring of the water outlet panel 8 is provided with spray channels 802, and the spray channels 802 communicate with the water outlet chamber 703.

[0043] In use, before rotating the switching valve core 7, the second regulating flow channel 705 on the outer ring of the valve core is precisely aligned with the second water outlet port 603 of the valve seat 1. At this time, the first regulating flow channel 704 is offset from the first water outlet port 602, and the first water outlet port 602 is blocked by the contact surface of the switching valve core 7. The water flows through the second water outlet port 603 into the water outlet chamber 703 on the bottom outer ring of the switching valve core 7. The annular layout of the water outlet chamber 703 makes the water flow evenly distributed to each spray channel 802 on the outer ring of the water outlet panel 8, and finally forms a stable annular spray effect.

[0044] After rotating the switching valve core 7, no water flows into the outlet chamber 703 due to the blockage of the second regulating flow channel 705, and the spray channel 802 is in a closed state. At the same time, the first regulating flow channel 704 on the switching valve core 7 is aligned with the first outlet channel 602, and the water flows into the emulsification chamber 702 through the first regulating flow channel 704, and works with the foaming component 9 to complete the gas-liquid mixing and foam generation. The first liquid inlet 103 simultaneously supplies liquid to the liquid storage chamber 501, and the pressure is adjusted by the piston push plate 504 to ensure stable foam output.

[0045] To ensure the foaming process, in one embodiment of the present invention, the foaming assembly 9 includes, from top to bottom, a flow guide shroud 901, a positioning sleeve 903, a foaming net 904, and a foamer base 905. The inner circumference of the foamer base 905 has several sets of vertically penetrating air intake channels 906 for introducing air when water flows through. The flow guide shroud 901 has circumferentially distributed flow guide ribs 902. The foamer base 905 has a mounting cavity 907 in the middle, and the positioning sleeve 903 and the foaming net 904 are arranged from top to bottom within the mounting cavity 907, with the outer diameter of the positioning sleeve 903 matching the inner diameter of the mounting cavity 907. The outer wall of the foamer base 905 has an external thread section, and the positioning sleeve 801 has an internal thread structure that mates with the external thread section. The top inner side of the positioning sleeve 801 has a sealing ring 908.

[0046] In use, following the top-to-bottom order, first place the guide shield 901 into the top of the mounting groove 907 of the foamer base 905, ensuring that the guide ribs 902 on the guide shield 901 face the direction of water flow; then insert the positioning sleeve 903 into the mounting groove 907, utilizing the fit between the outer diameter of the positioning sleeve 903 and the inner diameter of the mounting groove 907 to limit and fix the guide shield 901; finally, lay the foaming net 904 flat below the positioning sleeve 903, fitting it against the inner wall of the mounting groove 907 to complete the internal assembly of the component; holding the assembled foaming component 9, place the foamer base 9... Align the external thread of the foamer base 905 with the internal thread of the positioning sleeve 801 on the water outlet panel 8, and rotate the foamer base 905 clockwise until the thread is tightened in place, ensuring that the foaming component 9 is fixed inside the positioning sleeve 801, and that the flow guide 901 is directly opposite the water inlet of the emulsification chamber 702, and that the air intake channel 906 is unobstructed; after assembly, gently push the foaming component 9 to confirm that there is no looseness or displacement; observe the distribution of the flow guide ribs 902 to ensure that they are evenly surrounding the flow guide 901 without deformation or jamming; check whether the air intake channel 906 is vertically connected to avoid air intake obstruction due to assembly deviation;

[0047] Switching the device to foaming mode, water flows through the emulsification chamber 702 to the foaming component 9. The water first contacts the guide shroud 901, and under the guidance of the circumferentially distributed guide ribs 902, forms a spiral water flow, enhancing the turbulence effect. The spiral water flow flows downward in the mounting groove 907, and the increased water velocity generates negative pressure, automatically introducing external air through the air intake channel 906 on the inner circumference of the foamer base 905. The air and spiral water flow are fully mixed between the positioning sleeve 903 and the foaming net 904, forming a uniform gas-liquid mixture. When the gas-liquid mixture flows through the foaming net 904, it is divided and refined by the fine mesh of the foaming net 904, forming a fine and uniform foam, which is finally sprayed out from the bottom of the foamer base 905, completing the foaming process. The concentration and fineness of the foam can be adjusted by adjusting the liquid inlet flow rate in conjunction with the guiding effect of the guide ribs 902.

[0048] In order to filter the incoming water, as an embodiment of the present invention, a cylindrical filter element 4 is also provided inside the valve cover 3, and the first water inlet 102 and the second water inlet 105 are both located inside the filter element 4.

[0049] In use, open the snap-fit ​​connection between the valve cover 3 and the valve seat 1, and smoothly place the cylindrical filter element 4 inside the valve cover 3, ensuring that the axis of the filter element 4 is aligned with the axis of the valve cover 3 without tilting or offset; adjust the position of the filter element 4 so that the first water inlet 102 and the second water inlet 105 on the valve seat 1 are completely inside the filter element 4, ensuring that the water flow must be filtered by the filter element 4 before entering the first water inlet 102 and the second water inlet 105; re-snap and fix the valve cover 3 and the valve seat 1, ensuring that both ends of the filter element 4 are tightly fitted to the inner wall of the valve cover 3 and the upper surface of the valve seat 1, respectively, without any loose gaps; start the device to supply water briefly, and observe whether the water flow smoothly through the filter element 4 into the first water inlet 102 and the second water inlet 105, without any water leakage or obstruction.

[0050] External water flows into the valve cover 3 through the inlet pipe 2. Since the first inlet port 102 and the second inlet port 105 are located inside the filter element 4, the water will naturally flow to the outside of the filter element 4 and penetrate into the interior of the cylindrical filter element 4 through the side wall, thus achieving impurity interception and filtration. The clean water after being filtered by the filter element 4 converges inside the filter element 4 and flows to the corresponding flow channel of the valve seat 1 through the first inlet port 102 or the second inlet port 105, and finally flows to the foaming component 9 or the outlet chamber 703, preventing impurities from entering subsequent core components. During use, if a significant decrease in the liquid flow rate, a drop in water pressure, or uneven foam output is found, it may be due to a blockage in the filter element 4. The machine should be stopped and checked in time to avoid affecting the normal operation of the device due to a blockage in the filter element 4.

[0051] To facilitate the connection of the water inlet pipe 2, in one embodiment of the present invention, the water inlet pipe 2 includes a snap-fit ​​seat 201 integrally connected to the valve seat 1. A connecting pipe 202 is sleeved on the snap-fit ​​seat 201, and an inlet pipe 205 is connected to the side of the connecting pipe 202 away from the valve seat 1. The outer ring of the top end of the inlet pipe 205 forms a spherical structure, and a threaded connector 206 is ball-jointed to the top end of the inlet pipe 205. A slot 203 is provided on the side of the connecting pipe 202, and a snap-fit ​​groove 101 corresponding to the slot 203 is provided on the snap-fit ​​seat 201. A snap-fit ​​fastener 204 that cooperates with the snap-fit ​​groove 101 is inserted into the slot 203.

[0052] In use, align the connecting pipe body 202 with the integrated snap-fit ​​seat body 201 of the valve seat 1, and insert it into place along the outside of the snap-fit ​​seat body 201, ensuring that the slot 203 on the side of the connecting pipe body 202 is aligned with the snap-fit ​​groove 101 on the snap-fit ​​seat body 201; insert the fastener 204 from the slot 203 until the end of the fastener 204 is engaged in the snap-fit ​​groove 101, thereby fixing and locking the connecting pipe body 202 and the snap-fit ​​seat body 201, ensuring that the connection is secure; hold the threaded connector 206 at the top of the inlet pipe body 205, and use the spherical structure at the top of the inlet pipe body 205 to adjust the threaded connector. The angle of the head 206 ensures precise alignment between the connector interface and the external water supply pipe interface; rotate the threaded connector 206 to tighten it with the external pipe thread to ensure a tight seal at the connection point and no risk of leakage; after connection, gently pull the connecting pipe body 202 and the inlet pipe body 205 to confirm that the snap fastener 204 is securely engaged and the threaded connector 206 is tightened in place; start the external water supply and observe whether there is any water leakage at the connector connection point and the connection between the connecting pipe body 202 and the snap fastener 201, and at the same time check whether the water flow is smooth through the inlet pipe 2 into the valve cover 3 without any obstruction.

[0053] If there is a deviation in the external pipeline layout, the tilt angle of the threaded connector 206 can be finely adjusted through the spherical structure at the top of the inlet pipe 205. This allows for a smooth connection of the pipeline without disassembly and reconnection, avoiding installation stress or leakage caused by pipeline misalignment. When it is necessary to disassemble or replace the inlet pipe 2, first loosen the connection between the threaded connector 206 and the external pipeline, then pull out the clip 204 from the slot 203 of the connecting pipe 202. This will allow the connecting pipe 202 to be removed from the snap-fit ​​seat 201, completing the pipe disassembly. When replacing with a new pipe, simply reinstall it following the assembly steps described above. The operation is convenient.

[0054] To facilitate adjustment of the inlet flow rate of the inlet channel 505, as one embodiment of the present invention, such as... Figure 10 , 11As shown, the top of the valve cover 3 is provided with a mounting hole 301, and the mounting hole 301 is rotatably connected to an adjusting seat 10; the lower part of the adjusting seat 10 is provided with a positioning groove 1001 that cooperates with the top of the liquid storage cylinder 5, and the side of the adjusting seat 10 is provided with an inlet adjusting port 1002 corresponding to the liquid inlet channel 505.

[0055] In use, align the positioning groove 1001 at the bottom of the adjusting knob 10 with the top of the liquid storage cylinder 5 on the top of the valve cover 3, ensuring that the positioning groove 1001 fits snugly against the top of the liquid storage cylinder 5; insert the adjusting knob 10 into the mounting hole 301 on the top of the valve cover 3, so that the knob is rotatably connected to the mounting hole 301, ensuring that the adjusting knob 10 can rotate smoothly around the axis of the mounting hole 301 without jamming or loosening; rotate the adjusting knob 10 and observe the positional relationship between the liquid inlet adjustment port 1002 on the side of the knob and the liquid inlet flow channel 505 on the top of the liquid storage cylinder 5, ensuring that during the rotation of the adjusting knob 10, the liquid inlet adjustment port 1002 can be completely aligned, partially aligned, or completely offset from the liquid inlet flow channel 505 to meet different liquid inlet adjustment requirements; after assembly, gently rotate the knob to confirm that the positioning groove 1001 always fits snugly against the top of the liquid storage cylinder 5 without shifting or falling off;

[0056] Rotating the adjusting knob 10 clockwise gradually increases the overlap area between the liquid inlet regulating port 1002 on the side of the adjusting knob 10 and the liquid inlet flow channel 505 of the liquid storage cylinder 5, increasing the opening of the liquid inlet channel and increasing the liquid flow rate into the liquid storage chamber 501. This, in turn, increases the hydraulic driving force of the piston push plate 504, adapting to the application requirements of increased foaming concentration or increased water spray flow. Rotating the adjusting knob 10 counterclockwise gradually decreases the overlap area between the liquid inlet regulating port 1002 and the liquid inlet flow channel 505, reducing the opening of the liquid inlet channel and decreasing the liquid flow rate into the liquid storage chamber 501. This reduces the driving force of the piston push plate 504, achieving precise control of reduced foaming concentration or reduced water spray flow. Continuing to rotate the adjusting knob 10 until the liquid inlet regulating port 1002 and the liquid inlet flow channel 505 are completely misaligned, the liquid inlet channel is closed, the liquid storage chamber 501 stops receiving liquid, and the device can pause the foaming or water spraying function.

[0057] To prevent air from entering the valve cover 3 and impacting the foaming liquid inside the storage tank 5 after a prolonged water outage and subsequent water supply, as one embodiment of the present invention, such as... Figure 10 , 11 As shown, a floating slip ring 1003 is slidably connected to the outer side of the adjusting base 10. In the initial state, the floating slip ring 1003 corresponds to the liquid inlet adjusting port 1002. After the floating slip ring 1003 floats up, the liquid inlet adjusting port 1002 opens.

[0058] When in use, after water enters the device, the water exerts an upward force on the floating slip ring 1003, causing the floating slip ring 1003 to slide upward along the outside of the adjusting knob 10. After the floating slip ring 1003 floats up, it is completely offset from the liquid inlet adjusting port 1002, and the liquid inlet adjusting port 1002 opens automatically. The liquid enters the liquid storage chamber 501 through the adjusting port and the liquid inlet flow channel 505, ensuring the stable operation of the piston push plate 504. When the liquid inlet volume is manually adjusted by rotating the adjusting knob 10, the floating slip ring 1003 rotates synchronously with the adjusting knob 10. This avoids the situation where, after a long period of water outage, once the water supply is restarted, the air in the pipeline will quickly impact the inside of the device. At this time, the closed liquid inlet adjusting port 1002 can effectively prevent the air from impacting the liquid storage tank 5, causing the foaming liquid in the liquid storage tank 5 to be squeezed out by the air.

[0059] It should be noted that, in order to prevent the liquid storage cylinder 5 and the adjusting knob 10 from rotating synchronously, a protrusion is formed at the bottom of the liquid storage cylinder 5, and a groove is provided on the valve seat 1 to cooperate with the protrusion. The liquid storage cylinder 5 and the adjusting knob 10 are prevented from rotating synchronously by the protrusion and the groove engaging.

[0060] To prevent the floating slip ring 1003 from falling and affecting the response speed in subsequent use after each device is shut down, as an embodiment of the present invention, such as Figure 10 , 11 As shown, the bottom outer ring of the adjusting base 10 is provided with a positioning ring 1004, and the upper surface of the positioning ring 1004 is connected to a water-absorbing expansion member 1005, which is in contact with the lower surface of the floating slip ring 1003.

[0061] In use, first attach or snap the water-absorbing expansion component 1005 to the upper surface of the positioning ring 1004, ensuring that the water-absorbing expansion component 1005 is firmly installed, evenly distributed, and without loosening or falling off; then, fit the positioning ring 1004 with the water-absorbing expansion component 1005 assembled onto the bottom outer ring of the adjusting seat 10, and fix it with an interference fit or snap-fit ​​structure, so that the positioning ring 1004 and the adjusting seat 10 are coaxial, with the upper surface of the water-absorbing expansion component 1005 facing upwards and without tilting or offset; following the previous steps, fit the floating slip ring 1003 onto the outside of the adjusting seat 10, and adjust the initial position of the floating slip ring 1003 so that its lower surface is aligned with the water-absorbing expansion component 1004 on the positioning ring 1004. The water expansion component 1005 makes precise contact, and at this time, the floating slip ring 1003 can still completely block the liquid inlet adjustment port 1002; the sliding stroke of the floating slip ring 1003 is tested to ensure that the water expansion component 1005 does not hinder the floating slip ring 1003 from floating, and that the floating slip ring 1003 can always maintain contact with the water expansion component 1005 after sinking, forming a stable support; the adjustment knob 10 with the positioning ring 1004, water expansion component 1005, and floating slip ring 1003 assembled is inserted into the valve cover 3 mounting hole 301, and it is checked that the positioning ring 1004 does not interfere with the inner wall of the top of the valve cover 3, and the water expansion component 1005 is not deformed under pressure in the initial state;

[0062] After the device is started, water flows into the valve cover 3, and some of the water comes into contact with the water-absorbing expansion member 1005 on the positioning ring 1004. The water-absorbing expansion member 1005 gradually expands after absorbing water, forming a stable supporting force on the lower surface of the floating slip ring 1003. When the floating slip ring 1003 floats to the target position under water pressure, the expanded water-absorbing expansion member 1005 can support the floating slip ring 1003, preventing it from sinking rapidly due to gravity and maintaining a stable opening of the inlet regulating port 1002. After the device stops supplying water, the water-absorbing expansion member 1005 remains expanded, continuously supporting the floating slip ring 1003, keeping it in a position close to the open inlet regulating port 1002, rather than rapidly falling back to the initial blocked state. When the water supply resumes, the water flow will be... The floating slip ring 1003 needs to be re-driven to float significantly from its initial position, allowing it to quickly enter the liquid storage chamber 501 through the liquid inlet regulating port 1002, preventing air from impacting the piston push plate 504 in the pipeline, and simultaneously improving the device's response speed. When manually adjusting by rotating the regulating seat 10, the positioning ring 1004 and the water-absorbing expansion member 1005 rotate synchronously with the regulating seat 10, and the contact state between the water-absorbing expansion member 1005 and the lower surface of the floating slip ring 1003 remains unchanged. If the liquid inlet is manually increased, the floating slip ring 1003 floats up and compresses the water-absorbing expansion member 1005, without affecting the adjustment stroke. If the liquid inlet is manually decreased, the water-absorbing expansion member 1005 elastically resets, continuing to support the floating slip ring 1003 and preventing it from sinking rapidly and causing a sudden change in flow rate.

[0063] After a prolonged water outage, the water-absorbing expansion component 1005 gradually dehydrates and shrinks, causing the floating slip ring 1003 to fall and close the liquid inlet regulating port 1002 again. When water is supplied again and the device is turned on, air will quickly rush into the device. At this time, the closed liquid inlet regulating port 1002 can effectively prevent air from impacting the liquid storage tank 5, causing the foaming liquid in the liquid storage tank 5 to be squeezed out by the air. It can also prevent the abnormal liquid discharge caused by the large fluctuation of water pressure during the initial water supply, which impacts the piston push plate 504.

[0064] To facilitate the operation of the switching valve core 7, in one embodiment of the present invention, a wrench 11 is snapped onto the outside of the switching valve core 7, and the valve cover 3 is snapped onto the valve seat 1.

[0065] In use, after the switching valve core 7 is engaged with the wrench 11, the switching valve core 7 is rotated by the engaged wrench 11. When switching to the foaming mode, hold the wrench 11 engaged with the switching valve core 7 and rotate the wrench 11 clockwise to drive the switching valve core 7 to rotate synchronously, so that the first regulating flow channel 704 is aligned with the first water outlet 602. When switching to the normal spray mode, rotate the wrench 11 in the opposite direction to align the second regulating flow channel 705 with the second water outlet 603. The engaging design of the wrench 11 can enhance the operating torque, prevent slippage when manually rotating the switching valve core 7, and ensure that the flow channel is switched in place.

[0066] When using this invention, hold the assembled foaming component 9 by hand, align the external thread of the foamer base 905 with the internal thread of the positioning sleeve 801 on the water outlet panel 8, and tighten it clockwise to ensure that the guide cover 901 is directly facing the emulsification chamber 702 and the air intake channel 906 is unobstructed; embed the grid-shaped sealing gasket 701 into the top of the switching valve core 7 and make it fit flat; rotate the switching valve core 7 to the bottom of the valve seat 1 so that the sealing gasket fits tightly with the bottom of the valve seat 1, and the emulsification chamber 702 at the bottom of the valve core is directly facing the positioning sleeve 801; engage the wrench 11 with the adapter structure on the outside of the switching valve core 7, and gently turn the wrench 11 to confirm that there is no free rotation and that the switching valve core 7 can be driven to rotate synchronously; align the inner positioning frame 601 in the middle of the positioning plate 6 with the elliptical positioning frame 104 at the bottom of the valve seat 1 and engage it in place;

[0067] Align the connecting pipe 202 with the integrated snap-fit ​​seat 201 of the valve seat 1, and after inserting it, ensure that the slot 203 on the side of the connecting pipe 202 is aligned with the snap-fit ​​groove 101 of the snap-fit ​​seat 201. Insert the snap fastener 204 to snap it in place and ensure that there is no looseness. Hold the threaded connector 206 at the top of the liquid inlet pipe 205 and use the spherical structure to adjust the angle so that the connector is precisely aligned with the external water supply pipeline. Rotate the threaded connector 206 to tighten it. Gently pull the pipe to confirm that the snap fastener 204 and the threaded connector 206 are firmly fixed. Start the external water supply for a short test. If there is no leakage and the water flow is smooth, it is qualified.

[0068] Hold the locking wrench 11 on the switching valve core 7 and rotate the switching valve core 7 to align the first regulating flow channel 704 with the first water outlet 602; turn on the external water supply switch, and the water flows through the water inlet pipe 2 into the valve cover 3, permeating from the outside to the inside of the filter element 4, and entering the emulsification chamber 702 through the first water outlet 602 and the first regulating flow channel 704; the water flow forms a spiral flow under the guidance of the guide ribs 902, and the negative pressure generated by the increased flow velocity introduces air through the air intake channel 906, and the gas-liquid mixture is finely processed by the foaming net 904. After the liquid is dissolved, it forms a uniform foam that is sprayed out. At the same time, the first liquid inlet 103 supplies liquid to the liquid storage chamber 501, and the piston push plate 504 is hydraulically driven to slide and seal, which helps to adjust the liquid outlet pressure. Hold the wrench 11 and rotate the switching valve core 7 in the opposite direction to align the second regulating flow channel 705 with the second water outlet 603. The water flows through the second water outlet 603 and the second regulating flow channel 705 into the water outlet chamber 703 at the bottom outer ring of the switching valve core 7. The water is evenly distributed to the spray channel 802 on the outer ring of the water outlet panel 8 through the annular layout, forming a stable annular spray effect.

[0069] Hold the adjusting knob 10 and rotate it. Rotating clockwise increases the overlap area between the liquid inlet regulating port 1002 and the liquid inlet channel 505, increasing the liquid inlet volume and boosting the driving force of the piston pusher plate 504, thus increasing the foaming concentration. Rotating counterclockwise decreases the overlap area, reducing the liquid inlet volume and lowering the foaming concentration. Continue rotating until they are completely misaligned, closing the liquid inlet channel and pausing the foaming function. After water enters the device, the water can push the floating slip ring 1003 to float up along the adjusting knob 10, thereby automatically opening the liquid inlet regulating port 1002 and preventing air intake from affecting the normal operation of the foaming process. The water-absorbing expansion component 1005 expands after absorbing water, supporting the floating slip ring 1003 to prevent it from sinking quickly and maintaining a stable opening of the liquid inlet regulating port 1002. After water is stopped, the water-absorbing expansion component 1005 maintains a supported state, so the floating slip ring 1003 does not need to float up significantly when water is supplied again, improving the device's response speed and preventing air from impacting the piston pusher plate 504 in the pipeline.
