Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a water circuit board mechanism for a water purifier and a water purifier. Background Technology

[0002] The water circuit board is an integrated plate-shaped component inside a water purifier used to distribute, guide, and control water flow. It acts as the "vascular system" and "traffic hub" of the water purifier, integrating water circuits, reducing leak points, simplifying structure, saving space, and facilitating installation and maintenance. The check valve is a component installed on the water circuit board to ensure unidirectional water flow. Existing check valves are generally directly mounted to the outside of the water circuit board with screws. The water circuit board has two ports that connect to the two ends of the check valve. The two ends of the check valve must correspond one-to-one with the two ports, and both mating points must be sealed. Failure to seal at either mating point will lead to leakage, thus existing water circuit boards have a high risk of leakage. Furthermore, the check valve installed outside the water circuit board is a complete valve structure including the valve body and valve core, resulting in a large overall structure, high manufacturing costs, and the need for complete replacement during later maintenance, leading to high maintenance costs.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This utility model provides a water circuit board mechanism for a water purifier (hereinafter referred to as "water circuit board mechanism" for ease of description), such as Figures 1 to 3As shown, the water circuit board mechanism includes a water circuit board 100, a check valve core 200, a sealing member 300, and a first sealing member 400. The water circuit board 100 has interconnected water flow channels 101 and installation channels 102. The water flow channel 101 includes a valve mounting part 1011. One end of the installation channel 102 is connected to the valve mounting part 1011, and the other end forms an installation opening on the surface of the water circuit board 100. The check valve core 200 is disposed in the valve mounting part 1011, and the sealing member 300 is disposed in the installation channel 102. One end of the sealing member 300 presses against the check valve core 200. The sealing member 300 is detachably connected to the water circuit board 100. The first sealing member 400 is disposed between the sealing member 300 and the inner wall surface of the valve mounting part 1011. The check valve core 200 is configured to discharge water flowing in a first direction within the water channel 101 and to intercept water flowing in a second direction, the first and second directions being opposite in direction. The first direction is as follows: Figure 3 As shown in direction a, the second direction is as follows. Figure 3 The direction b is shown in the diagram.

[0035] When assembling the water circuit board mechanism, firstly, the check valve core 200 is placed into the installation channel 102 through the installation port, and then moved to the valve mounting part 1011 of the water flow channel 101 through the installation channel 102; then, the first sealing member 400 is installed on the sealing member 300; finally, the sealing member 300 is placed into the installation channel 102 through the installation port, so that one end of the sealing member 300 abuts against the check valve core 200, the position of the check valve core 200 is fixed by the sealing member 300, and the gap between the sealing member 300 and the installation channel 102 is sealed by the first sealing member 400.

[0036] Compared to existing technologies where the entire check valve is mounted outside the water manifold, the water manifold mechanism provided by this invention integrates the check valve core 200 within the water manifold 100 by providing interconnected water flow channels 101 and mounting channels 102. The check valve core 200 is then mounted to the valve mounting portion 1011 of the water flow channel 101 via the mounting channel 102. With the check valve core 200 integrated within the water manifold 100, the water flowing within the water flow channel 101 only has the risk of leakage from the mounting port. Compared to the two leakage points created by installing the check valve in existing technologies, this invention only has one leakage point, thus reducing the number of leakage points and lowering the risk of leakage. Furthermore, integrating the check valve core 200 within the water manifold 100 also helps improve the structural compactness of the water manifold mechanism, reducing its overall volume and contributing to its miniaturization. Furthermore, compared to the use of the entire check valve in the prior art, the check valve core 200 used in this water circuit board mechanism is only the valve core part of the check valve. Using the check valve core 200 helps to reduce the manufacturing cost of the entire water circuit board mechanism. If the check valve core 200 is damaged and needs to be replaced later, the maintenance cost is also lower.

[0037] In some embodiments, the water circuit panel 100 includes a plate portion 110 and an mounting pipe portion 120. The plate portion 110 contains most of the water flow channels 101, and the mounting pipe portion 120 contains an mounting channel 102 and a portion of the water flow channels 101. The portion of the water flow channels 101 formed within the mounting pipe portion 120 serves as a valve mounting portion 1011. Optionally, the water circuit panel 100 is a one-piece molded component, with the plate portion 110 and the mounting pipe portion 120 integrally molded during manufacturing. Of course, in other embodiments, the water circuit panel 100 can also be an assembly, where the plate portion 110 and the mounting pipe portion 120 are manufactured separately and then assembled together. It should be noted that in a water purifier, the check valve core 200 is generally installed downstream of the RO membrane filter element to prevent backflow of pure water; therefore, the pure water outlet of the RO membrane filter element is connected to the inlet of the water flow channel 101.

[0038] Continue to refer to Figure 3 As shown, the water flow channel 101 also includes an inlet section 1012 and an outlet section 1013. The valve mounting section 1011 is connected between the inlet section 1012 and the outlet section 1013, and the central axis of the inlet section 1012, the central axis of the valve mounting section 1011 and the central axis of the outlet section 1013 are arranged perpendicularly to each other.

[0039] The check valve core 200 includes a valve tube portion 210 and a valve body portion 220. The valve tube portion 210 is sleeved outside the valve body portion 220. After the check valve core 200 is installed into the valve mounting portion 1011, the valve tube portion 210 is located between the valve body portion 220 and the inner wall surface of the valve mounting portion 1011.

[0040] To improve the stability of the check valve core 200 within the valve mounting portion 1011, a first limiting surface is formed on the inner wall of the valve mounting portion 1011. The end face of the valve tube portion 210 away from the sealing member 300 abuts against the first limiting surface. A second limiting surface is formed on the inner wall of the valve tube portion 210, and the end face of the valve body portion 220 away from the sealing member 300 abuts against the second limiting surface. Since the end of the check valve core 200 closest to the sealing member 300 is held abutted by the sealing member 300, the first and second limiting surfaces can be used to limit the positions of both ends of the check valve core 200, thus improving the installation stability of the check valve core 200 within the valve mounting portion 1011.

[0041] Optionally, the valve body 220 includes a first valve body 221 and a second valve body 222, which are connected together by ultrasonic welding. This separate structure facilitates the manufacture of the valve body 220. The second valve body 222 has a plug-in portion 2221 at its end away from the first valve body 221. The valve body 220 also includes a helical spring (not shown in the figure), which is sleeved on the plug-in portion 2221 and fixed at both ends. When the valve body 220 is pushed by water flow and moves in the first direction, the end face of the valve body 220 away from the sealing member 300 separates from the second limiting surface of the valve pipe 210, forming a gap for water flow. During this process, the helical spring is compressed. When no water flow occurs, the helical spring releases its elastic potential energy, causing the valve body 220 to move in the second direction, thereby bringing the end face of the valve body 220 away from the sealing member 300 back into contact with the second limiting surface of the valve pipe 210.

[0042] Optionally, such as Figure 4 As shown, the valve tube section 210 includes a first tube section 211 and a second tube section 212 that are separately arranged. The second tube section 212 is disposed between the first tube section 211 and the sealing member 300. A plug ring 2121 is provided at the middle position of the second tube section 212, and the plug part 2221 of the second valve body 222 is inserted into the plug ring 2121.

[0043] To improve sealing, a second sealing element 600 is provided between the valve pipe portion 210 and the valve body portion 220. Optionally, the second sealing element 600 is a first sealing ring. To install the first sealing ring, a first mounting annular groove is provided on the valve body portion 220, and the first sealing ring is installed in the first mounting annular groove. To facilitate the formation of the first mounting annular groove, a first annular edge is provided on the first valve body 221, and an annular groove with one open end is provided on the second valve body 222. After the first valve body 221 and the second valve body 222 are assembled, the first annular edge seals the opening of the annular groove, thus forming the first mounting annular groove.

[0044] In some embodiments, a third seal 700 is provided between the inner wall surfaces of the valve tube portion 210 and the valve mounting portion 1011. Optionally, the third seal 700 is a second sealing ring. To install the second sealing ring, a second mounting ring groove is provided on the valve tube portion 210, and the second sealing ring is installed in the second mounting ring groove.

[0045] The sealing element 300 is installed inside the installation pipe section 120 and is detachably connected to the installation pipe section 120. In some embodiments, the installation pipe section 120 has a insertion channel 121 along a third direction, which is perpendicular to the central axis of the installation pipe section 120. The sealing element 300 has an annular slot 310 along the circumferential direction. The water circuit board mechanism also includes a pipe clamp 500, which passes through the insertion channel 121 and the annular slot 310. By using the pipe clamp 500 to fix the sealing element 300, the risk of water leakage caused by welding the sealing element 300 to the installation pipe section 120 can be avoided. It also facilitates after-sales maintenance and makes replacement easier.

[0046] Optionally, the pipe clamp 500 is a U-shaped clamp, which includes two clamping arms 510. The insertion channel 121 includes a first arc-shaped hole formed on one side of the mounting pipe portion 120 and a second arc-shaped hole formed on the other side of the mounting pipe portion 120. After the sealing member 300 is placed in the mounting pipe portion 120, the annular slot 310 communicates with both the first arc-shaped hole and the second arc-shaped hole. After the two clamping arms 510 of the U-shaped clamp are inserted into the first arc-shaped hole, they pass through both sides of the sealing member 300 and are inserted into the annular slot 310, and finally pass through the second arc-shaped hole.

[0047] In some embodiments, the first seal 400 has an annular structure, such as... Figure 5 As shown, the sealing member 300 includes a main body 320 extending along a first direction and two limiting rings 330 disposed on the main body 320. The limiting rings 330 are arranged circumferentially around the main body 320. The two limiting rings 330 are spaced apart in the first direction, and a sealing ring groove 340 is formed between the two limiting rings 330. The first sealing member 400 is disposed in the sealing ring groove 340.

[0048] Optionally, the first seal 400 includes at least two interconnected sealing rings 410. Multiple sealing rings 410 can improve the sealing performance between the sealing member 300 and the mounting tube 120. Optionally, the first seal 400 is an elastic rubber ring. Of course, in other embodiments, the first seal 400 can also be in other forms, such as sealing foam.

[0049] To facilitate the installation of the sealing component 300, two grooves 351 for inserting fingers are provided on the outer end face of the sealing component 300, and a pinch plate 352 is provided between the two grooves 351. By pinching the pinch plate 352, the sealing component 300 can be moved, which makes it convenient to insert the sealing component 300 into the installation tube 120, and also convenient to rotate the sealing component 300 to a suitable angle.

[0050] Continue to refer to Figure 5 As shown, the sealing component 300 also includes a sealing ring edge 350, the outer diameter of which is larger than the inner diameter of the mounting tube 120. When assembling the sealing component 300, the sealing ring edge 350 abuts against the end face of the mounting tube 120, thereby further improving the sealing performance at the mounting port.

[0051] This utility model also discloses a water purifier, which includes a housing and the aforementioned water circuit board mechanism, with the water circuit board mechanism disposed inside the housing. By using the aforementioned water circuit board mechanism, the water purifier has a low risk of leakage, high integration, low manufacturing cost, and low subsequent maintenance cost.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
