Description

Technical Field

[0001] This application relates to the field of shower technology, and more specifically, to a water outlet device and a shower including the water outlet device. Background Technology

[0002] When carbon dioxide gas mixes with water, the carbon dioxide in the water is absorbed into the body through the skin, promoting the dilation of capillaries, lowering blood pressure, improving cardiovascular function, and aiding blood circulation. Furthermore, the carbon dioxide gas in the water forms bubbles on the skin's surface, providing a gentle massage effect. Therefore, carbonated spring showers in current technology are very popular with consumers.

[0063] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0064] like Figures 1 to 3 As shown, the water outlet device 1 of this application embodiment includes an air supply section 1a and a gas-liquid mixing section 1b, wherein the air supply section 1a is detachably connected to the gas-liquid mixing section 1b. The air supply section 1a stores carbon dioxide gas, and when the air supply section 1a is connected to the gas-liquid mixing section 1b, the air supply section 1a can supply carbon dioxide gas to the gas-liquid mixing section 1b.

[0065] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to these processes, methods, products, or devices.

[0066] The gas-liquid mixing section 1b includes a water inlet connector 810, a water outlet connector 820, and an air inlet connector 830. The water inlet connector 810 is connected to a water supply pipe to allow water supplied by the pipe to enter the gas-liquid mixing section 1b. The water inlet connector 810 is connected to the outlet of a shower faucet (which dispenses a mixture of hot and cold water) via a hose. The water outlet connector 820 is connected to a water outlet via a hose; the outlet can be a handheld shower head, an overhead shower head, etc. In this embodiment, the water outlet connector 820 is directly connected to the handheld shower head via a hose. The air inlet connector 830 is detachably connected to the air supply section 1a; alternatively, the water inlet connector 810 can also be directly connected to municipal water via a hose.

[0067] When the gas supply section 1a is connected to the gas-liquid mixing section 1b, the carbon dioxide gas stored in the gas supply section 1a flows into the gas-liquid mixing section 1b through the gas inlet connector 830. The water flowing into the gas-liquid mixing section 1b through the water inlet connector 810 mixes with the carbon dioxide gas to form carbonated spring water. The carbonated spring water flows into the water outlet through the water outlet connector 820 for use by the user.

[0068] In one embodiment, the gas supply section 1a can be connected to the gas inlet connector 830 of the gas-liquid mixing section 1b via a quick-release assembly, but is not limited thereto.

[0069] like Figure 3 and Figure 4 As shown, the gas-liquid mixing section 1b includes a housing 600, a switching valve 100, a three-way connector 200, a water-gas linkage valve 300, a pneumatic control valve 400, a flow regulating valve 700, and a water valve body 500. The three-way connector 200, the water-gas linkage valve 300, the pneumatic control valve 400, and the water valve body 500 are housed within the housing 600. The switching valve 100 is connected to the housing 600, with a portion of the switching valve 100 exposed on the outer surface of the housing 600. Specifically, the switching valve 100 is a rotary valve; rotation allows for easy switching of the gas supply, facilitating user operation.

[0070] The inlet of the switch valve 100 is connected to the air inlet connector 830, and the outlet of the switch valve 100 is connected to the inlet of the tee connector 200. By controlling the opening or closing of the switch valve 100, it is possible to control whether the carbon dioxide gas supplied by the gas supply section 1a can enter the tee connector 200.

[0071] One outlet of the three-way connector 200 is connected to the pneumatic control valve 400, and the other outlet of the three-way connector 200 is connected to the flow regulating valve 700, and then to the water-gas linkage valve 300. In other words, the carbon dioxide gas supplied by the gas supply section 1a is split into two paths after passing through the three-way connector 200. One path enters the pneumatic control valve 400, and the other path enters the flow regulating valve 700 and the water-gas linkage valve 300.

[0072] Both the pneumatic control valve 400 and the water-gas linkage valve 300 are connected to the water circuit valve body 500 and communicate with the water flow channel within the water circuit valve body 500. One end of the water circuit valve body 500 is connected to the inlet connector 810, and the other end is connected to the outlet connector 820. The water-gas linkage valve 300 is used to control the opening or closing of the air supply channel between the air supply section 1a and the water-gas linkage valve 300 according to the pressure of the water flowing into the water-gas linkage valve 300, and is used to mix water and carbon dioxide gas to form carbonated spring water when the air supply channel is open.

[0073] like Figures 5 to 11As shown, the water-air linkage valve 300 includes an upper shell 310, a lower shell 320, a movable component 330, and a first elastic component 340. The upper shell 310 can be connected to the flow regulating valve 700 via an air pipe, and the upper shell 310 is provided with an air inlet channel 311. The air inlet channel 311 communicates with the flow regulating valve 700. The lower shell 320 is connected to the water circuit valve body 500, and the lower shell 320 is also connected to the upper shell 310. The lower shell 320 and the upper shell 310 form a cavity 321. The cavity 321 has a water passage cavity 322, a water passage hole 323, and a mixing cavity 324. The water passage cavity 322 communicates with the mixing cavity 324 through the water passage hole 323, and the inner wall of the cavity 321 is provided with a mating surface 325. The mixing cavity 324 communicates with the water outlet connector 820 through the water circuit valve body 500. The lower shell 320 also includes a water inlet 326, which communicates with the water passage cavity 322. Furthermore, the water inlet 326 is connected to the water inlet connector 810 via a water valve body 500. A movable member 330 is movably disposed within the cavity 321 between a closed position (closing the air intake passage 311) and an open position (opening the air intake passage 311). The movable member 330 has a pressure-bearing surface 333a that matches the shape of the mating surface 325; when the movable member 330 is in the closed position, the mating surface 325 and the pressure-bearing surface 333a are in zero-clearance fit, and at least a portion of the pressure-bearing surface 333a is located within the water passage cavity 322. When the movable member 330 is in the open position, the air intake passage 311 communicates with the mixing chamber 324. A first elastic member 340 provides an elastic force to the movable member 330 to move it towards the closed position.

[0074] When the water supply pipe supplies water to the inlet connector 810 and the switch valve 100 is in the open state, the water flows through the water valve body 500 and the inlet 326 before flowing into the water passage chamber 322. When the water pressure in the water passage chamber 322 is greater than or equal to the preset pressure value, the water flow pushes against the pressure-bearing surface 333a of the movable member 330, causing the movable member 330 to overcome the elastic force of the first elastic member 340 and move from the closed position to the open position, thereby opening the air intake passage 311 of the water-air linkage valve 300, so that the air supply part 1a supplies carbon dioxide gas to the water-air linkage valve 300 through the air intake passage 311. At the same time, since the air intake passage 311 is connected to the mixing chamber 324 when the movable member 330 is in the open position, the carbon dioxide gas supplied by the air supply part 1a can flow into the mixing chamber 324. Simultaneously, as the movable component 330 moves from the closed position to the open position, a gap is formed between the mating surface 325 and the pressure-bearing surface 333a. Water in the water passage cavity 322 passes through this gap and the water passage hole 323 into the mixing cavity 324. Carbon dioxide gas and water are fully mixed in the mixing cavity 324 to form carbonated spring water. The formed carbonated spring water flows into the outlet end through the water valve body 500 and the outlet connector 820.

[0075] In this embodiment of the water-gas linkage valve 300, when the movable member 330 is in the closed position, the mating surface 325 and the pressure-bearing surface 333a are in zero-clearance fit, and at least part of the pressure-bearing surface 333a is located within the water passage cavity 322. Thus, water flow essentially does not occur within the water passage cavity 322, resulting in a static water pressure within the water passage cavity 322. Because the water pressure within the water passage cavity 322 is static, the water pressure within the water passage cavity 322 is essentially equal to the inlet water pressure, meaning there is virtually no pressure loss. Since there is virtually no pressure loss, the inlet water pressure can be relatively reduced; that is, even when the inlet water pressure is low, the water pressure can still move the movable member 330 to the open position, ultimately opening the carbon dioxide gas passage. Therefore, the water-gas linkage valve 300 of this embodiment is applicable to environments with low inlet water pressure, thus having a wider range of applications.

[0076] It should be noted that hydrostatic pressure is relative to dynamic pressure. Hydrostatic pressure refers to the pressure of water that is not flowing, while dynamic pressure refers to the pressure of flowing water.

[0077] like Figure 7 and Figure 9 As shown, the mating surface 325 is formed on the inner wall of the water passage 323. Both the mating surface 325 and the pressure-bearing surface 333a are conical surfaces, and the two conical surfaces are fitted together. Fitting together means that the cone angles of the two conical surfaces are equal.

[0078] It is understood that, in the embodiments of this application, the shape of the pressure-bearing surface 333a is designed as a conical surface, which can make the movable member 330 subject to a larger force of water pressure, and further reduce the amount of water pressure required when the movable member 330 moves from the closed position to the open position.

[0079] like Figure 7 and Figure 9 As shown, along the moving direction of the movable member 330, the movable member 330 includes a first end 330a and a second end 330b. The first end 330a is used to close or open the air intake passage 311, and the second end 330b is provided with a pressure-bearing surface 333a. When the movable member 330 is in the closed position, a portion of the second end 330b extends into the water passage 323, and at least a portion of the pressure-bearing surface 333a is exposed outside the opening of the water passage 323.

[0080] The movable component 330 includes a first valve stem 331, a valve seat 332, and a first piston 333. The first valve stem 331 passes through the air intake passage 311 and is used to close or open the air intake passage 311. The valve seat 332 is connected to the first valve stem 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 shell 310. The first piston 333 is connected to the valve seat 332, and the first piston 333 is provided with a pressure-receiving surface 333a.

[0081] When the movable member 330 is in the closed position, part of the first piston 333 extends into the water passage 323.

[0082] like Figure 7 and Figure 9 As shown, a sealing element 312 is fixedly provided on the inner wall of the air intake passage 311, and an expanding portion 331a and a reducing portion 331b are provided on the outer periphery of the first valve stem 331. When the movable member 330 is in the closed position, the position of the expanding portion 331a corresponds to the position of the sealing element 312, and the expanding portion 331a compresses the sealing element 312, thus sealingly connecting it to the air intake passage 311 through the sealing element 312. When the movable member 330 is in the open position, the position of the reducing portion 331b corresponds to the position of the sealing element 312, and there is a gap between the reducing portion 331b and the sealing element 312. The size of the expanding portion 331a is larger than the size of the reducing portion 331b.

[0083] The first valve stem 331 is provided with a first air passage 331c, the valve seat 332 is provided with a second air passage 332a, and the first piston 333 is provided with an air outlet 333b. The first air passage 331c, the second air passage 332a, and the air outlet 333b are interconnected, and the air outlet 333b is connected to the water passage 323. When the movable member 330 is in the open position, the first air passage 331c is connected to the air inlet passage 311.

[0084] In the embodiments of this application, such as Figure 7 As shown, when the movable member 330 is in the closed position, the expanding portion 331a compresses the sealing member 312 and seals it with the air inlet channel 311 through the sealing member 312. At this time, the carbon dioxide gas supplied by the gas supply section 1a cannot flow into the first flow passage 331c through the air inlet channel 311, thus preventing the mixing of water and carbon dioxide gas. When the movable member 330 is in the open position, the expanding portion 331a moves upward, and the narrowing portion 331b corresponds to the position of the sealing member 312, with a gap between the narrowing portion 331b and the sealing member 312. The carbon dioxide gas supplied by the gas supply section 1a can flow into the first flow passage 331c through this gap, and then flow through the second flow passage 332a and the outlet 333b in sequence, ultimately achieving the mixing of water and carbon dioxide gas.

[0085] like Figure 9 As shown, when the movable member 330 is in the open position, the outlet end of the air vent 333b is located inside the water passage 323. The water passage area of ​​the water passage 323 is smaller than the water passage area of ​​the mixing chamber 324.

[0086] Understandably, when the movable component 330 is in the open position, since the outlet end of the vent 333b is located within the water passage 323, carbon dioxide gas is ejected from the vent 333b and directly enters the water passage 323, and then enters the mixing chamber 324. The carbon dioxide gas does not enter the water passage 322. The advantage of this is that most of the carbon dioxide gas mixes with the water flow in the mixing chamber 324, while the water flow does not mix with the carbon dioxide gas in the water passage 322. In other words, the carbonated water formed after the water flow and carbon dioxide gas mix almost never passes through the water passage 323. Thus, the carbonated water does not pass through the relatively small-diameter water passage 323, preventing the problem of reduced gas solubility due to decreased pressure, which could cause carbon dioxide gas to be released from the water and burst, creating noise.

[0087] Conversely, if the movable member 330 is in the open position and the outlet end of the vent 333b is located in the water passage 322, then carbon dioxide gas and water flow will mix in the water passage 322. The resulting carbonated water will then pass through the smaller-diameter water passage 323. According to Bernoulli's principle, when the carbonated water passes through the smaller-diameter water passage 323, the flow rate of the carbonated water increases while the internal pressure of the water decreases. Consequently, the solubility of the gas in the water decreases, causing carbon dioxide gas to be released from the water and burst, generating noise.

[0088] In one embodiment, the pressure surface 333a is conical, and the air outlet 333b is located at the apex of the conical surface.

[0089] like Figure 7 and Figure 9 As shown, the water-gas linkage valve 300 also includes a check valve assembly 350, which is connected to the valve seat 332 and disposed in the second flow passage 332a. It is used to allow gas to flow along the first flow passage 331c toward the outlet 333b, while blocking gas from flowing along the outlet 333b toward the first flow passage 331c.

[0090] like Figure 4 , Figure 10 , Figures 12 to 15 As shown, the water flow channels within the water valve body 500 include an inlet channel 510, a first branch channel 520, a second branch channel 530, and an outlet channel 540. The inlet channel 510 is connected to the inlet connector 810, the first branch channel 520 is connected to the inlet channel 510, and the second branch channel 530 is connected to the inlet channel 510. In other words, the water supplied by the water supply pipe is divided into two streams after passing through the inlet channel 510, one of which flows into the first branch channel 520, and the other flows into the second branch channel 530.

[0091] The pneumatic control valve 400 is connected to the switching valve 100. In this embodiment, the pneumatic control valve 400 is connected to the tee connector 200 via an air pipe. The pneumatic control valve 400 is used to control the opening or closing of the first branch flow channel 520 according to the opening or closing state of the switching valve 100. In this embodiment, when the switching valve 100 is in the closed state, the pneumatic control valve 400 opens the first branch flow channel 520, and the inlet flow channel 510 is connected to the outlet flow channel 540 through the first branch flow channel 520. At this time, water can flow into the outlet flow channel 540 through the first branch flow channel 520. When the switching valve 100 is in the closed state, the pneumatic control valve 400 closes the first branch flow channel 520, and the inlet flow channel 510 cannot be connected to the outlet flow channel 540 through the first branch flow channel 520. At this time, water cannot flow into the outlet flow channel 540 through the first branch flow channel 520.

[0092] The water-air linkage valve 300 is connected to the on / off valve 100 and the second branch flow channel 530, respectively. When the water pressure flowing into the water passage 322 of the water-air linkage valve 300 is greater than or equal to a preset pressure value, it opens the air supply channel between the air supply section 1a and the water-air linkage valve 300, mixing water and carbon dioxide gas. Furthermore, the water inlet flow channel 510 is connected to the water outlet flow channel 540 through the second branch flow channel 530 and the water-air linkage valve 300. When the water pressure flowing into the water passage 322 of the water-air linkage valve 300 is less than the preset pressure value, the water-air linkage valve 300 closes the air supply channel.

[0093] In the embodiments of this application, such as Figure 4 and Figure 10 As shown, the inlet 326 of the lower shell 320 of the water-gas linkage valve 300 is connected to the second branch flow channel 530, and the mixing chamber 324 of the water-gas linkage valve 300 is connected to the outlet flow channel 540 of the water valve body 500. Water flows through the second branch flow channel 530 and the inlet 326 into the water passage chamber 322, and then flows from the water passage chamber 322 through the water passage hole 323 into the mixing chamber 324. In the mixing chamber 324, the water mixes with carbon dioxide gas to form carbonated spring water, which flows through the outlet flow channel 540 to the outlet connector 820.

[0094] The connection between the water-gas interlock valve 300 and the gas supply section 1a can be referred to the above description of the water-gas interlock valve 300 and combined with... Figures 6 to 9 Therefore, we will not elaborate further here.

[0095] It should be noted that the gas supply channel between the gas supply section 1a and the water-gas linkage valve 300 may include a gas flow channel inside the switching valve 100, a gas flow channel inside the three-way connector 200, a gas pipe connecting the three-way connector 200 and the water-gas linkage valve 300, and an inlet gas flow channel 311 of the water-gas linkage valve 300. In this embodiment, the gas supply channel between the gas supply section 1a and the water-gas linkage valve 300 is opened or closed by opening or closing the inlet gas flow channel 311. Specifically, the opening or closing of the inlet gas flow channel 311 is achieved by moving the first valve stem 331, thereby controlling whether carbon dioxide gas enters the water-gas linkage valve 300.

[0096] The following is combined with Figure 4 The working principle of the water circuit and air circuit of the water outlet device 1 in the embodiment of this application is explained in detail.

[0097] When the switch valve 100 is in the open state, the pneumatic control valve 400 closes the first branch flow channel 520. At this time, water can only flow into the outlet flow channel 540 through the second branch flow channel 530, but cannot flow through the first branch flow channel 520. When the water flows into the water-air linkage valve 300 through the second branch flow channel 530, the water can push against the pressure surface 333a of the first piston 333, causing the first valve stem 331 to move upward and open the air intake channel 311. After carbon dioxide gas enters the water-air linkage valve 300, it mixes with the water to form carbonated spring water, which finally flows out of the outlet flow channel 540. Since only the second branch flow channel 530 has water flowing through at this time, a small flow of carbonated spring water flows out of the outlet flow channel 540.

[0098] When the switch valve 100 is closed, the pneumatic valve 400 opens the first branch flow channel 520. At this time, water can flow not only into the outlet flow channel 540 through the second branch flow channel 530, but also into the outlet flow channel 540 through the first branch flow channel 520. The two water flows merge in the outlet flow channel 540 to form a large flow of ordinary water. Since the switch valve 100 is closed at this time, carbonated spring water will not be produced.

[0099] Therefore, in the water outlet device 1 of this application embodiment, the air control valve 400 can control the opening or closing of the first branch flow channel 520 according to the opening or closing state of the switch valve 100, and the water-air linkage valve 300 can control the opening or closing of the air supply channel between the air supply part 1a and the water-air linkage valve 300 according to the water flow pressure flowing into the water-air linkage valve 300. In this way, by controlling the opening or closing of the switch valve 100, the water outlet device 1 can switch between spraying a small flow of carbonated spring water and a large flow of ordinary water. The two water outlet modes are available for users to choose from, which is convenient for users and improves the user experience.

[0100] like Figures 12 to 15As shown, the first branch flow channel 520 is further provided with an isolation section 550, which divides the first branch flow channel 520 into a first sub-flow channel 521 and a second sub-flow channel 522. The first sub-flow channel 521 is connected to the inlet flow channel 510, and the second sub-flow channel 522 is connected to the outlet flow channel 540. The pneumatic control valve 400 is used to open or close the flow channel between the first sub-flow channel 521 and the second sub-flow channel 522 by contacting or separating from the isolation section 550.

[0101] The first branch flow channel 520 has an opening 523 corresponding to the isolation section 550. A pneumatic control valve 400 is installed on the water valve body 500 and closes the opening 523. The first branch flow channel 520 also has an extension 560, forming a connection port 570 between the extension 560 and the isolation section 550. The first sub-flow channel 521 and the second sub-flow channel 522 are connected through the connection port 570. The pneumatic control valve 400 is used to open or close the connection port 570.

[0102] like Figure 13 and Figure 15 As shown, the pneumatic control valve 400 includes a valve housing 410, a valve cap 420, a second piston 430, a second valve stem 440, a pilot diaphragm 450, and a second elastic element 460. The valve housing 410 is connected to the water circuit valve body 500, and the valve housing 410 corresponds to the position of the opening 523. The valve cap 420 is connected to the end of the valve housing 410 facing away from the water circuit valve body 500. The valve cap 420 has a compression chamber 421 inside, which communicates with a three-way connector 200, allowing carbon dioxide gas to flow into the compression chamber 421 through the three-way connector 200. The second piston 430 is connected to one axial end of the second valve stem 440, and the second piston 430 and the second valve stem 440 are movably disposed within the valve housing 410 along the axial direction of the second valve stem 440. The pilot diaphragm 450 is fixed to the water circuit valve body 500 and closes the opening 523. Furthermore, the pilot diaphragm 450 closes the communication port 570. The pilot diaphragm 450 has pressure relief holes 451 extending through both sides of its thickness direction. The second piston 430 and the second valve stem 440 are both located on the side of the pilot diaphragm 450 facing away from the water valve body 500, and the second piston 430 and the second valve stem 440 can move between a blocked position (blocking the pressure relief holes 451) and a released position (releasing the pressure relief holes 451). One end of the second elastic member 460 abuts against the valve housing 410, and the other end abuts against the second piston 430, providing an elastic force to the second piston 430 and the second valve stem 440 to move them towards the release position.

[0103] like Figure 13As shown, when the switch valve 100 is in the open state, carbon dioxide gas flows into the squeezing chamber 421. Under the action of gas pressure, the second piston 430 overcomes the elastic force of the second elastic element 460, driving the second valve stem 440 to move towards the blocking position. After the other axial end of the second valve stem 440 blocks the pressure relief hole 451, the pilot diaphragm 450 closes the connecting port 570. At this time, the water flow cannot pass through the first branch flow channel 520, but can only pass through the second branch flow channel 530, and a small flow of carbonated spring water finally flows out of the outlet connector 820.

[0104] like Figure 15 As shown, when the switch valve 100 is in the closed state, no carbon dioxide gas is introduced into the squeezing chamber 421, and the second piston 430 has no gas pressure. Under the elastic force of the second elastic element 460, the second piston 430 drives the second valve stem 440 to move to the release position. After the pressure relief hole 451 is released at the other axial end of the second valve stem 440, the water flow pushes the pilot diaphragm 450 upward, so that the pilot diaphragm 450 opens the communication port 570. At this time, the water flow can flow into the outlet channel 540 through the first branch channel 520, and the outlet connector 820 finally discharges a large flow of ordinary water.

[0105] like Figure 13 and Figure 15 As shown, the second valve stem 440 includes a stem body 441 and a rubber gasket 442. One axial end of the stem body 441 is connected to the second piston 430, and the other axial end of the stem body 441 is connected to the rubber gasket 442. When the second valve stem 440 is in the blocking position, the rubber gasket 442 blocks the pressure relief hole 451.

[0106] The rod 441 and the second piston 430 can be connected by a screw connection, but are not limited to this.

[0107] It should be noted that, as Figure 4 and Figure 15 As shown, when the second valve stem 440 moves from the blocking position to the releasing position, the carbon dioxide gas in the compression chamber 421 is compressed by the second piston 430 and will move along... Figure 4 The gas flows back to the tee connector 200 in the direction of the dotted line to expel the gas in the extrusion chamber 421 and prevent the residual carbon dioxide gas in the extrusion chamber 421 from affecting the movement of the pilot diaphragm 450.

[0108] It is understood that the first elastic element 340 and the second elastic element 460 can be springs. Of course, in other embodiments, the first elastic element 340 and the second elastic element 460 can also be other components capable of providing elastic force, such as elastic rubber components.

[0109] It should be noted that the water outlet device in this embodiment may not include the water-gas linkage valve 300, but instead includes a gas supply section 1a, a switch valve 100, a water valve body 500, and a pneumatic control valve 400. The second branch flow channel 530 of the water valve body 500 is connected to the switch valve 100. When the switch valve 100 is in the open state, the carbon dioxide gas supplied by the gas supply section 1a enters the second branch flow channel 530, and the pneumatic control valve 400 closes the first branch flow channel 520. At this time, the water flows only through the second branch flow channel 530 into the outlet flow channel 540, and the water can mix with the carbon dioxide gas to form carbonated spring water. When the switch valve 100 is in the closed state, the pneumatic control valve 400 opens the first branch flow channel 520, and the water flows from the inlet flow channel 510 into the outlet flow channel 540 through the first branch flow channel 520 and the second branch flow channel 530 respectively, ultimately forming a large flow of ordinary water.
