[0036] Please refer to Figure 1 and Figure 2 In one embodiment, the integrated waterway plate includes a body 100, a control valve 200, a flow detection mechanism 300 and a positioning member 400. Figure 3 and Figure 4 A main channel 101 is provided in the main body 100, a control valve 200 is provided in the main channel 101 and is used to control the opening and closing of the main channel 101, a flow detection mechanism 300 is provided in the main channel 101 and is used to detect the flow of the main channel 101, and a positioning member 400 abuts between the control valve 200 and the flow detection mechanism 300 to position the control valve 200 and the flow detection mechanism 300.

[0037] The above-mentioned integrated waterway plate fixes the control valve 200 and the flow detection mechanism 300 in the main channel 101 through the positioning member 400, preventing the control valve 200 and the flow detection mechanism 300 from moving, thereby improving the stability of the structure; by integrating the control valve 200 and the flow detection mechanism 300 in the main channel 101, the flow of the main channel 101 can be more accurately counted, which is conducive to the miniaturized design of the integrated waterway plate.

[0038] It is understood that the aforementioned integrated waterway plate is used in a water purifier, which also includes a composite filter element and a reverse osmosis filter element, with the aforementioned integrated waterway plate positioned between the composite filter element and the reverse osmosis filter element. When the water purifier is in the water purification mode, the control valve 200 controls the main flow channel 101 to open. At this time, raw water flows sequentially through the composite filter element, the control valve 200, the positioning member 400, the flow detection mechanism 300, the main flow channel 101, the reverse osmosis filter element, and finally flows into the water purification branch.

[0039] In this embodiment, the control valve 200 is a solenoid valve that can be electrically opened and closed to achieve automatic control of the main channel 101, saving labor costs. In other embodiments, the control valve 200 can also be a mechanical valve, that is, the control valve 200 needs to be opened and closed manually.

[0040] In the examples of this application, please refer to Figure 4 The control valve 200 has a first flow passage 201, and the flow detection mechanism 300 has a second flow passage 301. The flow area of ​​the second flow passage 301 is larger than the flow area of ​​the first flow passage 201. Figure 4 The positioning member 400 has a third flow channel 401, the third flow channel 401 has a first end 401a and a second end 401b, the flow area of ​​the second end 401b is larger than the flow area of ​​the first end 401a, the first flow channel 201 is arranged at the first end 401a, and the second flow channel 301 is arranged at the second end 401b.

[0041] Here, when the water purifier is in the water purification state, the control valve 200 controls the main flow channel 101 to be open. At this time, the water will flow into the main flow channel 101 through the first flow channel 201, the third flow channel 401, and the second flow channel 301 in sequence. Since the flow area of ​​the second flow channel 301 is larger than the flow area of ​​the first flow channel 201, the third flow channel 401 is located between the first flow channel 201 and the second flow channel 301. In this way, by making the two ends of the third flow channel 401 have different flow areas, the flow areas of the second flow channel 301 and the first flow channel 201 can be transitioned, preventing the flow areas of the second flow channel 301 and the first flow channel 201 from changing suddenly and generating eddy currents, thereby preventing the eddy currents from affecting the detection accuracy of the flow detection mechanism 300.

[0042] In this embodiment, the inner diameter of the third flow channel 401 changes linearly along its own axial direction, so that the first end 401a and the second end 401b of the third flow channel 401 have different flow areas. Figure 1 , from the first end 401a to the second end 401b, the inner diameter of the third flow channel 401 increases linearly along its own axial direction, and the flow area of ​​the second end 401b is greater than the flow area of ​​the first end 401a.

[0043] In other embodiments, the inner diameter of the third flow channel 401 may also change nonlinearly along its own axial direction.

[0044] In the examples of this application, please refer to Figure 4 The control valve 200 includes a first plug-in portion 210 and a second plug-in portion 220 connected along the axis of the main channel 101. The first plug-in portion 210 is at least partially inserted into the main channel 101, and the outer wall of the first plug-in portion 210 abuts the inner wall of the main channel 101. The second plug-in portion 220 is used to abut the first end 401a of the positioning member 400. This arrangement allows the control valve 200 to be smoothly plugged into the integrated waterway plate and facilitates quick installation of the control valve 200.

[0045] Here, the outer diameter of the first plug part 210 is greater than that of the second plug part 220 , the outer diameter of the first plug part 210 is equal to the inner diameter of the main channel 101 , and the outer diameter of the second plug part 220 is smaller than the inner diameter of the main channel 101 .

[0046] In this embodiment, the first plug-in portion 210 and the second plug-in portion 220 are integrally formed, which has good integrity and high mechanical strength, and facilitates the rapid installation of the control valve 200. In other embodiments, the first plug-in portion 210 and the second plug-in portion 220 are split structures.

[0047] In the examples of this application, please refer to Figure 4 The first end 401a of the positioning member 400 is provided with a slot 410, and the second plug portion 220 is inserted into the slot 410. In this way, through the mutual cooperation of the second plug portion 220 and the slot 410, the first end 401a of the positioning member 400 and the control valve 200 can be limited and fixed.

[0048] In this embodiment, the second plug-in portion 220 is annular, and the slot 410 is also annular. In other embodiments, the second plug-in portion 220 can also be square or other shapes, and the slot 410 can also be square or other shapes.

[0049] In the examples of this application, please refer to Figure 4 Along the axis of the main channel 101, a gap exists between the second plug-in portion 220 and the wall of the slot 410. The integrated waterway plate also includes a seal 500 disposed within the gap. The seal 500 seals the second plug-in portion 220 and the slot 410, preventing water from leaking out.

[0050] Here, the axis direction of the main channel 101 is Figure 4 X direction shown.

[0051] Optionally, the sealing member 500 is a sealing ring, and the sealing ring can be made of rubber or silicone. The sealing ring is sleeved on the outer periphery of the second plug-in portion 220 and is tightly attached to the inner wall of the main channel 101 .

[0052] In this embodiment, the number of the sealing members 500 is not limited to one, that is, the number of the sealing members 500 can be at least two. When the number of the sealing members 500 is at least two, all the sealing members 500 can be arranged side by side along the axis of the main channel 101 .

[0053] In the examples of this application, please refer to Figure 4The flow detection mechanism 300 includes a rotating member 310 and a sensor 320. The rotating member 310 is rotatably disposed in the main channel 101 and has magnetism. The sensor 320 is disposed outside the main channel 101 and is in communication with the rotating member 310. When water flows in the main channel 101, the rotating member 310 rotates and generates a magnetic field. The sensor 320 senses the magnetic field and sends a signal indicating water flow, at which point the flow rate in the main channel 101 begins to be calculated. When water does not flow in the main channel 101, the rotating member 310 does not rotate and does not generate a magnetic field. The sensor 320 does not sense the magnetic field and sends a signal indicating no water flow, at which point the flow rate in the main channel 101 stops being calculated. This arrangement allows the sensor 320 to sense changes in water flow, thereby improving the accuracy of flow detection.

[0054] In this embodiment, the rotating member 310 is disposed within the main channel 101, and the sensor 320 is disposed outside the main channel 101. This reduces the risk of water leakage that would otherwise occur if the flow detection mechanism 300 were entirely installed within the main channel 101. Furthermore, since only the rotating member 310 is disposed within the main channel 101, the required installation volume of the flow detection mechanism 300 within the main channel 101 is reduced, thereby facilitating a miniaturized design of the water purifier. In other embodiments, both the rotating member 310 and the sensor 320 may be disposed within the main channel 101.

[0055] In this embodiment, a first mounting hole is defined in the sensor 320, and a second mounting hole is defined in the outer wall of the main channel 101. Fasteners are inserted through the first and second mounting holes to secure the sensor 320 to the outer wall of the main channel 101. Optionally, the fasteners are screws or bolts, and the sensor 320 is a Hall element.

[0056] In the examples of this application, please refer to Figure 4 The flow detection mechanism 300 further includes a main body 330, which has a cavity therein for accommodating the rotating member 310. The main body 330 is provided with a second flow passage 301 in communication with the cavity. With this arrangement, the rotating member 310 is rotatably disposed within the main body 330, effectively protecting the rotating member 310.

[0057] In this embodiment, only one rotating member 310 is disposed in the main body 330. In other embodiments, at least two rotating members 310 may be disposed in the main body 330, and all the rotating members 310 are spaced apart along the axis of the main body 330.

[0058] In this embodiment, the main body 330 and the rotating member 310 are separate structures, and the two are detachably connected. In other embodiments, the main body 330 and the rotating member 310 can also be an integrated structure, that is, the rotating member 310 is integrated into the main body 330.

[0059] In the examples of this application, please refer to Figure 4The main body 330 includes a first main body portion 331 and a second main body portion 332 connected along the axial direction of the main channel 101. The first main body portion 331 and the second main body portion 332 are detachably connected and enclosed to form a cavity. The end of the first main body portion 331 away from the second main body portion 332 abuts against the second end 401b of the positioning member 400. The inner wall of the main channel 101 is provided with a step surface 102, and the end of the second main body portion 332 away from the first main body portion 331 abuts against the step surface 102.

[0060] With this arrangement, the first main body portion 331 and the second main body portion 332 can be detachably connected, making it easy to open the cavity to replace or maintain the rotating member 310 in the cavity.

[0061] It should be noted that when the water purifier is in the water purification state, the control valve 200 controls the main channel 101 to open. At this time, the water flow will flow into the cavity through the first flow channel 201, the third flow channel 401, and the second flow channel 301 in sequence, causing the rotating part 310 in the cavity to rotate and flow out of the cavity to the main channel 101.

[0062] In this embodiment, the first main body 331 and the second main body 332 are detachably connected by plugging. In other embodiments, the first main body 331 and the second main body 332 can also be an integrally formed structure with good integrity and high mechanical strength.

[0063] In the examples of this application, please refer to Figure 4 and Figure 5 The integrated waterway board also includes a connecting pipe. The control valve 200 is located at one end of the main channel 101. The connecting pipe is at least partially inserted into the end of the main channel 101 away from the control valve 200. The connecting pipe is used to connect the main channel 101 and the pump body. Through this arrangement, the connecting pipe can be used to connect the integrated waterway board to other components.

[0064] In the examples of this application, please refer to Figure 4 and Figure 5 The inner wall of the main channel 101 is provided with a plurality of support ribs 103 , all of which are spaced apart along the circumference of the main channel 101 and are used to support and limit the connection pipe.

[0065] It is understood that the integrated waterway board is formed by injection molding. After the integrated waterway board is injection molded, the connecting pipe is inserted into the main channel 101 of the integrated waterway board. During the injection molding process of the integrated waterway board, if the wall thickness of the main channel 101 is too large, it is easy to shrink, resulting in a poor seal of the main channel 101 and a risk of water leakage.

[0066] Through the above arrangement, by providing a plurality of support ribs 103 on the inner wall of the main channel 101, the wall thickness of the main channel 101 is reduced, thereby improving the shrinkage caused by excessive wall thickness during injection molding of the integrated waterway plate, and greatly reducing the risk of shrinkage.

[0067] In this embodiment, the support ribs 103 may be cylindrical, prismatic, or in other shapes.

[0068] In this embodiment, the support ribs 103 are formed by injection molding. In other embodiments, the support ribs 103 can also be formed by riveting or welding.

[0069] Please refer to Figure 1 , a water purifier in one embodiment includes the above-mentioned integrated waterway plate.

[0070] Here, the above-mentioned water purifier further includes a composite filter element and a reverse osmosis filter element, and the integrated waterway plate is arranged between the composite filter element and the reverse osmosis filter element. Figures 2 to 4 When the water purifier is in the water purification state, the control valve 200 controls the main channel 101 to open. At this time, the raw water flows through the composite filter element, the integrated waterway plate, the reverse osmosis filter element, and then flows into the water purification branch. If the composite filter element is clogged, the flow rate of the integrated waterway plate will decrease.

[0071] In the above-mentioned water purifier, the flow detection mechanism 300 is integrated into the integrated waterway plate, which is located between the composite filter element and the reverse osmosis filter element. Based on the flow detection results flowing through the integrated waterway plate, the user is reminded to replace the composite filter element, which indirectly extends the life of the reverse osmosis filter element and reduces the cost of replacing the element.

[0072] Specifically, the composite filter element is used to filter large particles of impurities, rust, mud and sand in the raw water, and the reverse osmosis filter element is used to filter small particles of impurities in the raw water.

[0073] Optionally, the composite filter element may be a composite of polypropylene, carbon fiber, and a post-positioned carbon rod, or a composite of polypropylene, a carbon rod, and an ultrafiltration membrane.

[0074] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
