Description

Technical Field

[0001] This application relates to the technical field of showers, and specifically to a water-gas interlocking valve, a carbonated spring generator including the water-gas interlocking valve, and a shower including the carbonated spring generator.

Background Art

[0002] The water-gas interlocking valve, also called a water-gas interlocking device, is used to open the gas passage when the pressure of the water flow flowing into the water-gas interlocking valve is large enough, and to close the gas passage when the pressure of the water flow flowing into the water-gas interlocking valve is insufficient or there is no water flow.

[0003] After carbon dioxide gas is mixed with water, the carbon dioxide gas in the water is absorbed by the skin and enters the body, thus promoting the dilation of microvessels, lowering blood pressure, improving cardiovascular function, contributing to blood circulation in blood vessels, and also, the carbon dioxide gas in the water presents bubbles on the surface of the skin and has a slight massage effect. Therefore, the carbonated spring shower in the prior art is favored by many consumers.

[0004] The water-gas interlocking valve can be applied to a carbonated spring shower so that the carbonated spring shower discharges carbonated spring water. When the pressure of the water flow flowing into the water-gas interlocking valve is large enough, the gas passage is opened and the water flow and carbon dioxide gas are mixed to form carbonated spring water. When the pressure of the water flow flowing into the water-gas interlocking valve is insufficient or there is no water flow, the gas passage cannot be opened, and thus, carbonated spring water cannot be formed.

[0005] However, in the water-gas interlocking valve in the prior art, it is necessary to let a water flow with a large enough water pressure flow in to open the gas passage, and in an environment with low water pressure, the gas passage cannot be opened.

Thereby, the gas flows into the mixing chamber through the intake passage and mixes with water. Therefore, the water-gas interlocking valve of the embodiment of the present application is applicable to an environment with a low water inlet pressure, and has a wider application range.

Embodiments for Carrying Out the Invention

[0022] Now, exemplary embodiments will be more comprehensively described with reference to the drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided so that this application is comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed descriptions will be omitted.

[0023] As shown in FIGS. 1 to 3, the carbonated spring generator 1 of the embodiment of the present application includes an air supply part 1a and a gas-liquid mixing part 1b, and the air supply part 1a is removably connected to the gas-liquid mixing part 1b. Carbon dioxide gas is stored in the air supply part 1a, and when the air supply part 1a and the gas-liquid mixing part 1b are connected, the air supply part 1a can provide carbon dioxide gas to the gas-liquid mixing part 1b.

[0024] It can be understood that the terms "comprising" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not necessarily limited to the steps or units already listed, and may further optionally include steps or units not listed, or other steps or modules inherent to these processes, methods, products or devices.

[0025] The gas-liquid mixing part 1b is provided with a water inlet joint 810, a water outlet joint 820 and an air intake joint 830. The water inlet joint 810 is connected to one water supply pipe and is used to allow the water flow provided by the water supply pipe to enter the gas-liquid mixing part 1b. The water inlet joint 810 is connected to the water outlet end of a shower nozzle (the shower nozzle can discharge the mixed water after adjusting the temperature of cold water and hot water) via a hose, and the water outlet joint 820 is connected to one water outlet end via a hose. The water outlet end may be a hand-held shower head, an overhead shower, etc. In this embodiment, the water outlet joint 820 is directly connected to the hand-held shower head via a hose. The air intake joint 830 is used to be removably connected to the air supply part 1a. Of course, the water inlet joint 810 may be directly connected to the municipal water via a hose.

[0026] When the air supply part 1a is connected to the gas-liquid mixing part 1b, the carbon dioxide gas stored in the air supply part 1a flows into the gas-liquid mixing part 1b through the air intake joint 830. The water flow that enters the gas-liquid mixing part 1b from the water inlet joint 810 is mixed with the carbon dioxide gas to form carbonated spring water, and the carbonated spring water flows into the water outlet end through the water outlet joint 820 for the user to use.

[0027] In one embodiment, the air supply part 1a can be connected to the air intake joint 830 of the gas-liquid mixing part 1b by a quick disconnect module, but it is not limited thereto.

[0028] As shown in FIGS. 3 and 4, the gas-liquid mixing part 1b is provided with a housing 600, an on-off valve 100, a three-way joint 200, a water-gas interlocking valve 300, a gas control valve 400, a flow regulating valve 700 and a waterway valve body 500. The three-way joint 200, the water-gas interlocking valve 300, the gas control valve 400 and the waterway valve body 500 are provided in the housing 600. The on-off valve 100 is connected to the housing 600, and a part of the on-off valve 100 is exposed on the outer surface of the housing 600. Specifically, a rotary on-off valve is adopted for the on-off valve 100, and the gas can be opened and closed by rotation, which is easy for the user to operate.

[0029] The inlet of the on-off valve 100 communicates with the intake joint 830, and the outlet of the on-off valve 100 communicates with the inlet of the three-way joint 200. By controlling the on or off of the on-off valve 100, it is possible to control whether the carbon dioxide gas provided from the air supply part 1a enters the three-way joint 200 or not.

[0030] One of the outlets of the three-way joint 200 communicates with the gas control valve 400, and the other outlet of the three-way joint 200 communicates with the flow rate regulating valve 700 and then communicates with the water-gas interlocking valve 300. In other words, the carbon dioxide gas provided from the air supply part 1a is divided into two after passing through the three-way joint 200, one of which enters the gas control valve 400 and the other enters the flow rate regulating valve 700 and the water-gas interlocking valve 300.

[0031] Both the gas control valve 400 and the water-gas interlocking valve 300 are connected to the waterway valve body 500 and communicate with the waterway flow path in the waterway valve body 500. One end of the waterway valve body 500 is connected to the water inlet joint 810, and the other end of the waterway valve body 500 is connected to the water outlet joint 820. The water-gas interlocking valve 300 is used to control the opening or closing of the air supply passage between the air supply part 1a and the water-gas interlocking valve 300 based on the magnitude of the pressure of the water flow flowing into the water-gas interlocking valve 300, and is used to mix the water flow and the carbon dioxide gas to form carbonated spring water when the air supply passage is open.

[0032] As shown in FIGS. 5 to 11, the water-gas interlocking valve 300 includes a case 300a, a movable member 330, and a first elastic member 340. The case 300a may include an upper case 310 and a lower case 320. The upper case 310 can be connected to the flow rate regulating valve 700 via a gas pipe, and an intake air flow path 311 is provided in the upper case 310. The intake air flow path 311 communicates with the flow rate regulating valve 700. The lower case 320 is connected to the water path valve body 500, and the lower case 320 is connected to the upper case 310. The lower case 320 and the upper case 310 surround to form a single cavity 321. The cavity 321 has a first water inlet flow path 322 and a mixing chamber 324, and the mixing chamber 324 has an inlet 323 communicating with the first water inlet flow path 322. A first fitting surface 325 is provided on the inner wall of the inlet 323. The mixing chamber 324 communicates with the water outlet joint 820 via the water path valve body 500. The lower case 320 further includes a water inlet 326, and the water inlet 326 communicates with the first water inlet flow path 322. And the water inlet 326 communicates with the water inlet joint 810 via the water path valve body 500. The movable member 330 is provided in the cavity 321 of the case 300a so as to be movable between a first position for closing the intake air flow path 311 and a second position for opening the intake air flow path 311. The movable member 330 is provided with a second fitting surface 333a that conforms to the shape of the first fitting surface 325. When the movable member 330 is in the first position, the first fitting surface 325 and the second fitting surface 333a are fitted without a gap to block the communication between the first water inlet flow path 322 and the mixing chamber 324, and at least a part of the second fitting surface 333a is located in the first water inlet flow path 322. When the movable member 330 is in the second position, there is a gap between the first fitting surface 325 and the second fitting surface 333a, the first water inlet flow path 322 and the mixing chamber 324 are communicated, and the movable member 330 opens the intake air flow path 311 to communicate the intake air flow path 311 and the mixing chamber 324. The first elastic member 340 is used to provide an elastic force for the movable member 330 to move to the first position.

[0033] When the water supply pipe supplies water to the water inlet joint 810 and the on-off valve 100 is in the on state, the water flow passes through the waterway valve body 500 and the water inlet 326 and then flows into the first water inlet passage 322. When the pressure of the water flow in the first water inlet passage 322 is equal to or greater than a preset pressure value, the water flow presses against the second fitting surface 333a of the movable member 330. As a result, the movable member 330 moves from the first position to the second position against the elastic force of the first elastic member 340, opening the intake passage 311 of the water-gas interlocking valve 300. Thus, the air supply part 1a provides carbon dioxide gas into the water-gas interlocking valve 300 through the intake passage 311. At the same time, when the movable member 330 is located at the second position, since the intake passage 311 communicates with the mixing chamber 324, the carbon dioxide gas provided from the air supply part 1a can flow into the mixing chamber 324. At the same time, since the movable member 330 moves from the first position to the second position, a gap is formed between the first fitting surface 325 and the second fitting surface 333a, and the water flow in the first water inlet passage 322 passes through the gap and the inlet 323 and enters the mixing chamber 324. After the carbon dioxide gas and the water flow are sufficiently mixed in the mixing chamber 324, carbonated spring water is formed. The formed carbonated spring water passes through the waterway valve body 500 and the water outlet joint 820 and flows into the water outlet end.

[0034] In the water-gas interlocking valve 300 according to the embodiment of the present application, when the movable member 330 is located at the first position, the first fitting surface 325 and the second fitting surface 333a are fitted without a gap, and at least a part of the second fitting surface 333a is located in the first water inlet passage 322. By doing so, the water flow hardly flows in the first water inlet passage 322, and the pressure of the water flow in the first water inlet passage 322 becomes a hydrostatic pressure. Since the pressure of the water flow in the first water inlet passage 322 is a hydrostatic pressure, the pressure of the water flow in the first water inlet passage 322 is approximately equal to the incoming water pressure, that is, the pressure of the water flow hardly loses. Since the pressure of the water flow hardly loses, the incoming water pressure can be relatively reduced. That is, even when the incoming water pressure is at a low water pressure, the movable member 330 can be moved to the second position by the water pressure, and finally the gas passage of the carbon dioxide gas can be opened. Therefore, the water-gas interlocking valve 300 according to the embodiment of the present application is applicable to an environment with a low incoming water pressure, and the applicable range is wider.

[0035] Note that hydrostatic pressure is relative to hydrodynamic pressure. Hydrostatic pressure is the pressure of water that is hardly flowing, and hydrodynamic pressure is the pressure of flowing water.

[0036] Note that when the movable member 330 is in the first position, the fact that the first fitting surface 325 and the second fitting surface 333a are fitted without a gap can be understood as meaning that there is absolutely no gap between the first fitting surface 325 and the second fitting surface 333a. Of course, due to the influence of machining errors or mounting errors, there may be a small gap between the first fitting surface 325 and the second fitting surface 333a, and the gap may be, for example, 0.2 mm or less.

[0037] As shown in FIGS. 7 and 9, the first fitting surface 325 is formed on the inner wall of the inlet 323. The shapes of the first fitting surface 325 and the second fitting surface 333a are both conical surfaces, and the two conical surfaces are fitted. Among them, the fact that the two conical surfaces are fitted means that the taper angles of the two conical surfaces are equal.

[0038] In the embodiment of the present application, by designing the shape of the second fitting surface 333a as a conical surface, it can be understood that the force acting on the movable member 330 by the water pressure can be increased, and the magnitude of the water pressure required when the movable member 330 moves from the first position to the second position can be further reduced.

[0039] As shown in FIGS. 7 and 9, along the moving direction of the movable member 330, the movable member 330 includes a first end 330a and a second end 330b provided oppositely. The first end 330a is used to close or open the intake passage 311, and the second fitting surface 333a is provided at the second end 330b. When the movable member 330 is in the first position, a part of the second end 330b enters the inlet 323, and at least a part of the second fitting surface 333a is located in the first water inlet passage 322.

[0040] The mixing chamber 324 is located at the second end 330b of the movable member 330. Further, along the moving direction of the movable member 330, the mixing chamber 324 and the movable member 330 are linearly arranged.

[0041] An air flow passage 360 is provided inside the movable member 330. When the movable member 330 is in the second position, the intake air passage 311 communicates with the mixing chamber 324 through the air flow passage 360. The air flow passage 360 extends along the moving direction of the movable member 330.

[0042] It can be understood that by providing the air flow passage 360 inside the movable member 330, the structure of the water gas interlocking valve can be made more compact.

[0043] In the embodiment of the present application, the movable member 330 includes a first valve rod 331, a valve seat 332, and a first piston 333. The first valve rod 331 is inserted into the intake air passage 311 and is used to close or open the intake air passage 311. The valve seat 332 is connected to the first valve rod 331. One end of the first elastic member 340 abuts against the valve seat 332, and the other end abuts against the inner wall surface of the upper case 310. The first piston 333 is connected to the valve seat 332, and a second fitting surface 333a is provided on the first piston 333.

[0044] When the movable member 330 is in the first position, a part of the first piston 333 enters into the inlet 323.

[0045] As shown in FIGS. 7 and 9, a sealing material 312 is fixedly provided on the inner wall surface of the intake air passage 311, and a diameter-expanded portion 331a and a diameter-reduced portion 331b are provided on the outer periphery of the first valve rod 331. When the movable member 330 is in the first position, the position of the diameter-expanded portion 331a corresponds to the position of the sealing material 312, and the diameter-expanded portion 331a presses the sealing material 312, and is hermetically connected to the intake air passage 311 by the sealing material 312. When the movable member 330 is in the second position, the position of the diameter-reduced portion 331b corresponds to the position of the sealing material 312, and there is a gap between the diameter-reduced portion 331b and the sealing material 312. The size of the diameter-expanded portion 331a is larger than the size of the diameter-reduced portion 331b.

[0046] The first valve rod 331 is provided with a first gas passage flow path 331c, the valve seat 332 is provided with a second gas passage flow path 332a, the first piston 333 is provided with an exhaust hole 333b, and the first gas passage flow path 331c, the second gas passage flow path 332a, and the exhaust hole 333b communicate with each other, and the exhaust hole 333b communicates with the inlet 323. When the movable member 330 is in the second position, the first gas passage flow path 331c communicates with the intake flow path 311.

[0047] The ventilation flow path 360 includes the first gas passage flow path 331c, the second gas passage flow path 332a, and the exhaust hole 333b.

[0048] In the embodiment of the present application, as shown in FIG. 7, when the movable member 330 is in the first position, the enlarged diameter portion 331a presses the sealing material 312, and the sealing material 312 seals and connects to the intake flow path 311. In this case, the carbon dioxide gas provided from the air supply portion 1a cannot flow into the first gas passage flow path 331c through the intake flow path 311. Therefore, the mixing of the water flow and the carbon dioxide gas cannot be realized. When the movable member 330 is in the second position, the enlarged diameter portion 331a moves upward, the reduced diameter portion 331b corresponds to the position of the sealing material 312, and there is a gap between the reduced diameter portion 331b and the sealing material 312. The carbon dioxide gas provided from the air supply portion 1a can flow into the first gas passage flow path 331c through the gap, and can sequentially flow through the second gas passage flow path 332a and the exhaust hole 333b, and finally the mixing of the water flow and the carbon dioxide gas is realized.

[0049] When the movable member 330 is in the second position, one end of the ventilation flow path 360 along the moving direction of the movable member 330 is located inside the inlet 323 of the mixing chamber 324.

[0050] In the embodiment of the present application, as shown in FIG. 9, when the movable member 330 is in the second position, the outlet end of the exhaust hole 333b is located inside the inlet 323. The water passage area of the inlet 323 is smaller than the water passage area of the mixing chamber 324.

[0051] When the movable member 330 is located at the second position, since the outlet end of the exhaust hole 333b is located within the inlet 323, carbon dioxide gas jets out from the exhaust hole 333b and then directly enters the inlet 323. After that, it enters the mixing chamber 324. It can be understood that the carbon dioxide gas does not enter the first water inlet passage 322. The advantage of this is that most of the carbon dioxide gas is mixed with the water flow within the mixing chamber 324, and the water flow does not mix with the carbon dioxide gas in the first water inlet passage 322. That is to say, the carbonated spring water formed after the water flow and the carbon dioxide gas are mixed hardly passes through the inlet 323. In this way, the carbonated spring water does not pass through the inlet 323 with a small pore diameter. Therefore, due to the decrease in the pressure degree, the gas solubility decreases, and the problem that carbon dioxide gas is released from the water and ruptures to generate noise does not occur.

[0052] Conversely, when the movable member 330 is located at the second position, if the outlet end of the exhaust hole 333b is located within the first water inlet passage 322, the carbon dioxide gas and the water flow are mixed in the first water inlet passage 322, and the carbonated spring water formed after mixing passes through the inlet 323 with a small pore diameter. As can be seen from Bernoulli's theorem, when the carbonated spring water passes through the inlet 323 with a small pore diameter, the flow rate of the carbonated spring water increases and the internal pressure degree of the water body decreases. Therefore, the gas solubility in the water body decreases, and the carbon dioxide gas is released from the water body and ruptures to generate noise.

[0053] In one embodiment, the shape of the second fitting surface 333a is a conical surface, and the exhaust hole 333b is provided at the apex of the conical surface.

[0054] As shown in FIGS. 7 and 9, the water-gas interlocking valve 300 further includes a backflow prevention module 350. The backflow prevention module 350 is connected to the valve seat 332 and is provided within the second gas passage 332a. It is used to allow the gas to flow along the first gas passage 331c in the direction of the exhaust hole 333b and prevent the gas from flowing along the exhaust hole 333b in the direction of the first gas passage 331c.

[0055] As shown in FIGS. 4, 10, 12 to 15, the water flow path in the water valve body 500 includes a second water inlet flow path 510, a first branch flow path 520, a second branch flow path 530, and a water outlet flow path 540. The second water inlet flow path 510 communicates with the water inlet joint 810, the first branch flow path 520 communicates with the second water inlet flow path 510, and the second branch flow path 530 communicates with the second water inlet flow path 510. In other words, the water flow supplied from the water supply pipe is divided into two water flows after passing through the second water inlet flow path 510, one of which flows into the first branch flow path 520 and the other flows into the second branch flow path 530.

[0056] The gas control valve 400 communicates with the on-off valve 100. In the embodiment of the present application, the gas control valve 400 communicates with the three-way joint 200 via a gas pipe. The gas control valve 400 is used to control the opening or closing of the first branch flow path 520 according to the on or off state of the on-off valve 100. In the embodiment of the present application, when the on-off valve 100 is in the off state, the gas control valve 400 opens the first branch flow path 520, and the second water inlet flow path 510 communicates with the water outlet flow path 540 via the first branch flow path 520. In this case, the water flow can pass through the first branch flow path 520 and flow into the water outlet flow path 540. When the on-off valve 100 is in the off state, the gas control valve 400 closes the first branch flow path 520, and the second water inlet flow path 510 cannot communicate with the water outlet flow path 540 via the first branch flow path 520. In this case, the water flow cannot pass through the first branch flow path 520 and flow into the water outlet flow path 540.

[0057] The water-gas interlocking valve 300 communicates with the on-off valve 100 and the second branch flow path 530 respectively. When the pressure of the water flow flowing into the first water inlet flow path 322 of the water-gas interlocking valve 300 is equal to or greater than a preset pressure value, the air supply passage between the air supply part 1a and the water-gas interlocking valve 300 is opened and used to mix the water flow and carbon dioxide gas. And the second water inlet flow path 510 communicates with the water outlet flow path 540 via the second branch flow path 530 and the water-gas interlocking valve 300. When the pressure of the water flow flowing into the first water inlet flow path 322 of the water-gas interlocking valve 300 is less than the preset pressure value, the water-gas interlocking valve 300 closes the air supply passage.

[0058] In the embodiment of the present application, as shown in FIGS. 4 and 10, the water inlet 326 of the lower case 320 of the water-gas interlocking valve 300 communicates with the second branch flow path 530, and the mixing chamber 324 of the water-gas interlocking valve 300 communicates with the water outlet flow path 540 of the water path valve body 500. The water flow passes through the second branch flow path 530 and the water inlet 326 and enters the first water inlet flow path 322, and then flows from the first water inlet flow path 322 through the inlet 323 into the mixing chamber 324. In the mixing chamber 324, the water flow and the carbon dioxide gas are mixed to form carbonated spring water, and the carbonated spring water flows through the water outlet flow path 540 to the water outlet joint 820.

[0059] The communication between the water-gas interlocking valve 300 and the air supply part 1a can be obtained by combining FIGS. 6 to 9 with reference to the above introduction of the water-gas interlocking valve 300, and will not be repeatedly described here.

[0060] In addition, the air supply passage between the air supply part 1a and the water-gas interlocking valve 300 may include the gas flow path inside the on-off valve 100, the gas flow path inside the three-way joint 200, the gas pipe communicating between the three-way joint 200 and the water-gas interlocking valve 300, and the intake air flow path 311 of the water-gas interlocking valve 300. In the embodiment of the present application, by opening or closing the intake air flow path 311, the air supply passage between the air supply part 1a and the water-gas interlocking valve 300 is opened or closed. Specifically, the movement of the first valve rod 331 realizes the opening or closing of the intake air flow path 311, and controls whether the carbon dioxide gas enters the inside of the water-gas interlocking valve 300.

[0061] Hereinafter, in connection with FIG. 4, the operating principles of the water path and the gas path of the carbonated spring generator 1 of the embodiment of the present application will be described in detail.

[0062] When the on-off valve 100 is in the on state, the gas control valve 400 closes the first branch flow path 520. In this case, the water flow cannot pass through the first branch flow path 520 and can only flow into the outlet water flow path 540 through the second branch flow path 530. After the water flow passes through the second branch flow path 530 and flows into the water-gas interlocking valve 300, the water flow presses against the second fitting surface 333a of the first piston 333, moves the first valve rod 331 upward, and can open the intake air flow path 311. After the carbon dioxide gas enters the water-gas interlocking valve 300, it mixes with the water flow to form carbonated spring water, and finally the carbonated spring water flows out from the outlet water flow path 540. In this case, since the water flow only passes through the second branch flow path 530, a small flow rate of carbonated spring water flows out from the outlet water flow path 540.

[0063] When the on-off valve 100 is in the off state, the gas control valve 400 opens the first branch flow path 520. In this case, the water flow can not only flow into the outlet water flow path 540 through the second branch flow path 530, but also flow into the outlet water flow path 540 through the first branch flow path 520, and the two water flows merge in the outlet water flow path 540 to form ordinary water with a large flow rate. In this case, since the on-off valve 100 is turned off, no carbonated spring water is generated.

[0064] As can be seen from the above, in the carbonated spring water generator 1 of the embodiment of the present application, the gas control valve 400 can control the opening or closing of the first branch flow path 520 according to the on or off state of the on-off valve 100, and the water-gas interlocking valve 300 can control the opening or closing of the air supply passage between the air supply part 1a and the water-gas interlocking valve 300 based on the magnitude of the water flow pressure flowing into the water-gas interlocking valve 300. In this way, by controlling the on or off of the on-off valve 100, the carbonated spring water generator 1 can switch between the ejection of small-flow carbonated spring water and the ejection of large-flow ordinary water. The two water outlet modes can be selected by the user, which not only provides convenience for the user but also improves the user experience.

[0065] As shown in FIGS. 12 to 15, a partition 550 is further provided in the first branch flow path 520. The partition 550 divides the first branch flow path 520 into a first sub-flow path 521 and a second sub-flow path 522. The first sub-flow path 521 communicates with the second water inlet flow path 510, and the second sub-flow path 522 communicates with the water outlet flow path 540. The gas control valve 400 is used to open or close the flow path between the first sub-flow path 521 and the second sub-flow path 522 by contacting or separating from the partition 550.

[0066] An opening 523 corresponding to the partition 550 is provided in the first branch flow path 520. The gas control valve 400 is attached to the water valve body 500 and closes the opening 523. A stretching portion 560 is further provided in the first branch flow path 520. A communication port 570 is formed between the stretching portion 560 and the partition 550. The first sub-flow path 521 and the second sub-flow path 522 communicate with each other through the communication port 570. The gas control valve 400 is used to open or close the communication port 570.

[0067] As shown in FIGS. 13 and 15, the gas control valve 400 includes a valve case 410, a bonnet 420, a second piston 430, a second valve rod 440, a pilot diaphragm 450, and a second elastic member 460. The valve case 410 is connected to the waterway valve body 500 and corresponds to the position of the opening 523. The bonnet 420 is connected to one end of the valve case 410 facing away from the waterway valve body 500. The interior of the bonnet 420 has a pressure chamber 421, and the pressure chamber 421 communicates with the three-way joint 200, and carbon dioxide gas can flow into the pressure chamber 421 from the three-way joint 200. The second piston 430 is connected to one end in the axial direction of the second valve rod 440, and the second piston 430 and the second valve rod 440 are provided in the valve case 410 so as to be movable along the axial direction of the second valve rod 440. The pilot diaphragm 450 is fixedly provided on the waterway valve body 500 and closes the opening 523. Further, the pilot diaphragm 450 closes the communication port 570. The pilot diaphragm 450 is provided with pressure relief holes 451 penetrating both surfaces on both sides in the thickness direction thereof. The second piston 430 and the second valve rod 440 are both provided on the side of the pilot diaphragm 450 facing away from the waterway valve body 500, and the second piston 430 and the second valve rod 440 can move between a closed position closing the pressure relief holes 451 and a release position releasing the pressure relief holes 451. The second elastic member 460 has one end abutted against the valve case 410 and the other end abutted against the second piston 430, and is used to provide an elastic force for moving the second piston 430 and the second valve rod 440 to the release position.

[0068] As shown in FIG. 13, when the on-off valve 100 is in the on state, carbon dioxide gas flows into the pressure chamber 421, and the second piston 430 moves the second valve rod 440 against the elastic force of the second elastic member 460 under the action of the gas pressure to the closed position. After the other end in the axial direction of the second valve rod 440 closes the pressure relief holes 451, the pilot diaphragm 450 closes the communication port 570. In this case, the water flow cannot pass through the first branch flow path 520 and can only pass through the second branch flow path 530, and finally, carbonated spring water with a small flow rate flows out from the water outlet joint 820.

[0069] As shown in Fig. 15, when the on-off valve 100 is in the off state, carbon dioxide gas is not injected into the pressing chamber 421. In this case, no air pressure acts on the second piston 430. The second piston 430 is moved by the elastic force of the second elastic member 460 to move the second valve rod 440 to the release position. After the other end in the axial direction of the second valve rod 440 releases the pressure relief hole 451, the water flow presses against the pilot diaphragm 450 to move upward, thereby opening the communication port 570 by the pilot diaphragm 450. In this case, the water flow can pass through the first branch flow path 520 and flow into the water outlet flow path 540, and finally a large flow of ordinary water flows out from the water outlet joint 820.

[0070] As shown in Figs. 13 and 15, the second valve rod 440 includes a rod body 441 and a rubber cushion 442. One end in the axial direction of the rod body 441 is connected to the second piston 430, and the rubber cushion 442 is connected to the other end in the axial direction of the rod body 441. When the second valve rod 440 is located at the closed position, the rubber cushion 442 closes the pressure relief hole 451.

[0071] The connection method between the rod body 441 and the second piston 430 may be screwed, but is not limited thereto.

[0072] As shown in Figs. 4 and 15, when the second valve rod 440 moves from the closed position to the release position, the carbon dioxide gas in the pressing chamber 421 is refluxed to the three-way joint 200 along the broken line direction in Fig. 4 under the pressing of the second piston 430, discharging the gas in the pressing chamber 421 and avoiding the residual carbon dioxide gas in the pressing chamber 421 from affecting the movement of the pilot diaphragm 450.

[0073] It can be understood that the first elastic member 340 and the second elastic member 460 may be springs. Of course, in other embodiments, the first elastic member 340 and the second elastic member 460 may be other components that can provide elastic force, for example, elastic rubber materials.
