Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and more particularly to a water circuit controller capable of controlling the switching of two filter cartridges in a water treatment system to a series or parallel connection. This utility model further relates to a water circuit control valve and a water treatment system. Background Technology

[0002] With increasing emphasis on health and concerns about water pollution, water treatment machines or systems have become common household appliances. Water treatment machines, especially household ones such as central water purifiers and water softeners, are often installed in kitchens to treat water and obtain cleaner water.

[0003] To obtain sufficiently clean water or water that meets specific requirements, such as water suitable for direct drinking, existing water treatment systems often have more than one filter cartridge. However, most water treatment systems in China are installed under the kitchen countertop and are relatively small (larger water treatment systems are difficult to install under the countertop). To improve water treatment efficiency, small water treatment systems are generally equipped with two filter cartridges to increase the number of filter cartridges while maintaining the height of the water treatment system, thereby improving water treatment effectiveness. For example, many water purifiers are equipped with two purification filter cartridges to perform multi-stage purification of raw water or increase the volume of treated water. In addition, small water softeners have less softening resin and are less effective. To improve softening efficiency, small water softeners are also generally equipped with two softening filter cartridges to increase the amount of softening resin while maintaining the height of the water softener. For water softeners with dual softening filters, a series structure can increase the layer height of the softening resin, thereby improving the softening effect, while a parallel structure can increase the water flow. Generally, in areas with high-hardness raw water, a series structure water softener is suitable. In multi-person households, where multiple shower devices are installed, the requirement for soft water flow is relatively high, making a parallel structure water softener more suitable.

[0004] However, existing water circuit controllers in water treatment systems often only allow control over the connection status of a single filter cartridge. For example, some water treatment machines can only control two filter cartridges connected in series or in parallel. This causes inconvenience for users. Utility Model Content

[0103] Refer to the attached diagram in the instruction manual. Figures 1A to 10A water treatment system according to an embodiment of the present invention is described, wherein the water treatment system includes a water circuit controller 1, a first filter element 31, and a second filter element 32. The water circuit controller 1 includes a water circuit control valve 10 and a set of connecting pipes 20. The water circuit control valve 10 includes a valve body 11 and a valve core 12. The connecting pipe set 20 includes a first connecting pipe 21, a second connecting pipe 22, a third connecting pipe 23, a fourth connecting pipe 24, a fifth connecting pipe 25, and a sixth connecting pipe 26. The valve body 11 of the water circuit control valve 10 has a valve cavity 110. The first connecting pipe 21 connects to the valve body 11 of the water circuit control valve 10 and communicates with a first communication opening 3101 of the first filter element 31. The second connecting pipe 22 connects to the first filter element 31. The valve body 11 is connected to the second communication opening 3102 of the first filter element 31. The third connecting pipe 23 is connected to the valve body 11 of the water circuit control valve 10 and to the first conduction opening 3201 of the second filter element 32. The fourth connecting pipe 24 is connected to the valve body 11 of the water circuit control valve 10 and to the second conduction opening 3202 of the second filter element 32.

The sixth connecting pipe 26 is connected to the valve body 11 of the water circuit control valve 10 and to the water supply mechanism, such as the water supply tap of the water treatment system of this utility model (or it can be connected to the filter element outlet port of the softening control valve). In other words, one end of the first connecting pipe 21, one end of the second connecting pipe 22, one end of the third connecting pipe 23, one end of the fourth connecting pipe 24, one end of the fifth connecting pipe 25, and one end of the sixth connecting pipe 26 of the connecting pipe assembly 20 are respectively connected to the valve body 11. Preferably, the valve core 12 and the valve cavity 110 are respectively arranged to extend linearly, so that the connecting pipe assembly 20 of the water circuit controller 1 can be easily connected to the first filter element 31 and the second filter element 32, and the valve core 12 is also arranged in the valve cavity 110 for easy assembly and disassembly.

[0104] As shown in the attached image. Figures 1A to 10As shown, in the water treatment system according to this embodiment, the valve core 12 of the water circuit control valve 10 of the water circuit controller 1 is disposed in the valve cavity 110 of the valve body 11, thereby enabling the water circuit control valve 10 to have a series working position and a parallel working position. When the valve core 12 of the water circuit control valve 10 is rotated to position the water circuit control valve 10 in the series working position, the fifth connecting pipe 25 and the first connecting pipe 21 are connected through the first connecting channel 1001, and the second connecting pipe 22 and the third connecting pipe 23 are connected through the... The valve body 11 and valve core 12 of the water circuit control valve 10 are connected to form a second connecting channel 1002. The fourth connecting pipe 24 and the sixth connecting pipe 26 are connected through a third connecting channel 1003, so that the water to be treated (or raw water) can flow from the fifth connecting pipe 25 to the first connecting pipe 21 under water pressure. After the raw water is purified (or softened) by the first filter element 31, the first-stage treated water flows out through the second connecting pipe 22 and flows to the third connecting pipe 23. Then, after further purification (or softening) by the second filter element 32, the second-stage treated water is obtained. Water is supplied via the fourth connecting pipe 24 to the sixth connecting pipe 26; when the valve core 12 of the water circuit control valve 10 is rotated to put the water circuit control valve 10 in the parallel working position, the fifth connecting pipe 25 and the first connecting pipe 21 are connected through the first connecting channel 1001, the fourth connecting pipe 24 and the sixth connecting pipe 26 are connected through the third connecting channel 1003, and the fifth connecting pipe 25 and the third connecting pipe 23 are connected through the fourth connecting channel formed by the valve body 11 and the valve core 12 of the water circuit control valve 10. The second connecting pipe 22 and the sixth connecting pipe 26 are connected via a fifth connecting channel 1005 formed by the valve body 11 and the valve core 12 of the water circuit control valve 10. This allows raw water to flow from the fifth connecting pipe 25 to the first connecting pipe 21 and the third connecting pipe 23 under water pressure. After the water to be treated (or raw water) is purified (or softened) by the first filter element 31 and the second filter element 32, the resulting treated water flows through the second connecting pipe 22 and the fourth connecting pipe 24 to the sixth connecting pipe 26 and is supplied. Accordingly, when the water circuit control valve 10 of the water treatment system of this utility model is in the series working position, the first filter element 31 and the second filter element 32 are controlled to be connected in series. When the water circuit control valve 10 of the water treatment system of this utility model is in the parallel working position, the first filter element 31 and the second filter element 32 are controlled to be connected in parallel.Furthermore, when the water circuit control valve 10 of the water treatment system of this utility model is in the series working position, and the first filter element 31 and the second filter element 32 are softening filter elements, the first filter element 31 and the second filter element 32 connected in series are regenerated, which can make more effective use of regenerated salt and achieve the effect of saving salt (because it is a series structure, the regenerated brine can flow through the two softening filter elements in sequence. The water flowing out of the first softening filter element still contains unexchanged sodium ions, so the water flowing out of the first softening filter element continues to flow into the second softening filter element for regeneration and exchange, so that the brine is utilized more fully).

The fifth channel 105 is connected to the second channel 102 and the fourth channel 104 respectively, thereby forming the fifth connecting channel 1005 which is connected to the second opening 1102 and the sixth opening 1106 respectively. Preferably, the first connecting channel 1001 is formed by the valve chamber 110. It can be understood that the first connecting channel 1001 can also be a separate channel formed in the valve body 11 and connected to the first opening 1101 and the fifth opening 1105 respectively. Preferably, the inner diameters of the valve cavity 110 and the fourth channel 104 are increased, or in other words, the inner diameters of the valve cavity 110 and the fourth channel 104 are made as large as possible.

[0110] As shown in the attached image. Figures 4A to 10 As shown, further, when the moving valve plate 122 of the water circuit control valve 10 of the water circuit controller 1 of the water treatment system according to the present utility model embodiment is driven to rotate so that the water circuit control valve 10 is in the bypass working position, the first channel 101 of the valve core 12 is connected to the valve cavity 110 and the fourth channel 104 respectively, so that the raw water can flow from the fifth opening 1105 through the valve cavity 110, the first channel 101 and the fourth channel 104 to the sixth opening 1106 and be supplied through the sixth connecting pipe 26. That is, the first channel 101 is connected to the fourth channel 104, thereby forming the sixth connecting channel 1006 that is connected to the fifth opening 1105 and the sixth opening 1106 respectively.

[0111] As shown in the attached image. Figures 4A to 10 As shown, preferably, in the water treatment system of this utility model, the first channel 101 of the water control valve 10 of the water controller 1 is a channel provided on the moving valve plate 122 of the valve core 12 and connected to the valve cavity 110; the second channel 102 is a through hole extending from the second opening 1102 of the valve body 11 to the first fluid control surface 1210 of the fixed valve plate 121 of the valve core 12; the third channel 103 is a through hole extending from the third opening 1103 of the valve body 11 to the first fluid control surface 1210 of the fixed valve plate 121 of the valve core 12; the fourth channel 104 is a through hole extending from the sixth opening 1106 of the valve body 11 to the first fluid control surface 1210 of the fixed valve plate 121 of the valve core 12; and the fifth channel 105 is a blind hole extending from the second fluid control surface 1220 of the moving valve plate 122. It can be understood that the fixed valve plate 121 of the valve core 12 of the water circuit control valve 10 of this utility model can be regarded as being integrally formed with the valve body 11.

[0112] As shown in the attached image. Figure 7A As shown, when the water circuit control valve 10 of the water circuit controller 1 of the water treatment system according to this utility model embodiment is in the series working position, the first channel 101 is blocked by the fixed valve plate 121, and one end of the fourth channel 104 extending to the first fluid control surface 1210 of the fixed valve plate 121 of the valve core 12 is blocked by the moving valve plate 122. (See attached figures) Figure 7C As shown, when the water control valve 10 of the water controller 1 according to the present utility model embodiment is in the bypass working position, one end of the second channel 102 extending to the first fluid control surface 1210 of the fixed valve plate 121 of the valve core 12 is blocked by the moving valve plate 122, and the fifth channel 105 is connected to the third channel 103, but cannot form an effective water flow path.

[0113] As shown in the attached image. Figures 8A to 10 As shown, the water circuit controller 1 of the water treatment system according to an embodiment of the present invention further includes a set of seals 124, wherein the seals 124 are disposed outside the movable valve plate 122 of the water circuit control valve 10 to prevent raw water from leaking from the valve chamber 110. In other words, the movable valve plate 122 of the water circuit control valve 10 is disposed between the seals 124 and the fixed valve plate 121.

[0114] As shown in the attached image. Figures 8A to 10As shown, the water circuit control valve 10 of the water circuit controller 1 of the water treatment system according to an embodiment of the present invention further includes an operating end 123, wherein the operating end 123 is disposed on the outside of the valve core 12. More specifically, the operating end 123 is disposed on the moving valve plate 122 of the water circuit control valve 10, so that an operator can drive the moving valve plate 122 of the valve core 12 to rotate relative to the fixed valve plate 121 through the operating end 123.

[0115] As shown in the attached image. Figure 7A and Figure 10 As shown, optionally, when the user rotates the moving valve plate 122 of the valve core 12 to a suitable position through the operating end 123 of the valve core 12, the water circuit control valve 10 is in the series working position; when the user rotates the moving valve plate 122 of the valve core 12 to another suitable position through the operating end 123 of the valve core 12, the water circuit control valve 10 is in the parallel working position; when the user rotates the moving valve plate 122 of the valve core 12 to another suitable position through the operating end 123 of the valve core 12, the water circuit control valve 10 is in the bypass working position.

[0116] Accordingly, in the water treatment system of the present invention, the first opening 1101 and the fifth opening 1105 of the water control valve 10 of the water controller 1 are connected through the valve chamber 110, so that the raw water does not pass through the valve core 12, but flows directly to the first filter element 31 through the valve chamber 110. The fourth opening 1104 and the sixth opening 1106 are kept in communication, so that the treated water flowing out of the second filter element 32 does not pass through the valve core 12, but flows directly to the sixth opening 1106 through the fourth opening 1104 and is supplied through the sixth connecting pipe 26. The raw water in this water treatment system is not controlled by the valve core 12, but flows directly to the first filter element 31 through the valve chamber 110. The treated water flowing out of the second filter element 32 is not controlled by the valve core 12, but flows directly to the sixth opening 1106 through the fourth opening 1104. This reduces the structural complexity of the valve core 12 of the water circuit controller 10 in this water treatment system, and reduces the number of through holes in the fixed valve plate 121 and the moving valve plate 122 of the valve core 12. This allows the valve core 12 to achieve series, parallel, and bypass control of the first filter element 31 and the second filter element 32 using as few through holes as possible. Furthermore, with the reduced number of through holes in the fixed valve plate 121 and the moving valve plate 122 of the valve core 12, the inner diameter of the through holes in the fixed valve plate 121 and the moving valve plate 122 of the valve core 12 can be increased. Furthermore, since the first opening 1101 and the fifth opening 1105 of the water circuit control valve 10 are connected through the valve chamber 110, the raw water flows directly through the valve chamber 110 to the first filter element 31, and the treated water flowing out from the second filter element 32 flows directly through the fourth opening 1104 to the sixth opening 1106. This allows the inner diameter of the raw water supply channel and the inner diameter of the treated water outflow channel to be set as large as possible, so as to maximize the raw water inflow rate and the treated water flow rate, thereby improving the water treatment speed of the entire water treatment system.

The second connecting pipe 22 connects to the valve body 11A of the water circuit control valve 10A and communicates with the first communication opening 3101 of the first filter element 31 of the water treatment system of the present invention. The first filter element 31 of the water treatment system is connected to the second connecting opening 3102. The third connecting pipe 23 is connected to the valve body 11A of the water control valve 10A and to the first conducting opening 3201 of the second filter element 32 of the water treatment system of this utility model.

The sixth connecting pipe 26 is connected to the valve body 11A of the water control valve 10A and to the water supply mechanism, such as the water supply tap of the water treatment system of this utility model (or it can be connected to the filter element outlet port of the softening control valve). In other words, one end of the first connecting pipe 21, one end of the second connecting pipe 22, one end of the third connecting pipe 23, one end of the fourth connecting pipe 24, one end of the fifth connecting pipe 25, and one end of the sixth connecting pipe 26 of the connecting pipe assembly 20 are respectively connected to the valve body 11A. Preferably, the valve core 12A and the valve cavity 110A are respectively arranged to extend linearly, so that the connecting pipe assembly 20 of the water circuit controller 1A can easily connect to the first filter element 31 and the second filter element 32, and also so that the valve core 12A is disposed in the valve cavity 110A and is easy to disassemble and assemble.

The fourth connecting pipe 24 and the sixth connecting pipe 26 are connected through the third connecting channel 1003A, so that the water to be treated (or raw water) can flow from the fifth connecting pipe 25 to the first connecting pipe 21 under water pressure. After the raw water is purified (or softened) by the first filter element 31, the first-stage treated water flows out through the second connecting pipe 22 and flows to the third connecting pipe 23. Then, after further purification (or softening) by the second filter element 32, the second-stage treated water is obtained. The treated water flows through the fourth connecting pipe 24 to the sixth connecting pipe 26 and is supplied; when the valve core 12A of the water circuit control valve 10A is rotated to put the water circuit control valve 10A in the parallel working position, the fifth connecting pipe 25 and the first connecting pipe 21 are connected through the first connecting channel 1001A, the fourth connecting pipe 24 and the sixth connecting pipe 26 are connected through the third connecting channel 1003A, and the fifth connecting pipe 25 and the third connecting pipe 23 are connected through the fourth connecting channel formed by the valve body 11A and the valve core 12A of the water circuit control valve 10A.

After the water to be treated (or raw water) is purified (or softened) by the first filter element 31 and the second filter element 32 respectively, the resulting treated water flows through the second connecting pipe 22 and the fourth connecting pipe 24 to the sixth connecting pipe 26 and is supplied. Accordingly, when the water circuit control valve 10A of the water treatment system of this utility model is in the series working position, the first filter element 31 and the second filter element 32 are controlled to be connected in series; when the water circuit control valve 10A of the water treatment system of this utility model is in the parallel working position, the first filter element 31 and the second filter element 32 are controlled to be connected in parallel.

The fifth channel 105A is connected to both the second channel 102A and the fourth channel 104A, thereby forming the fifth connecting channel 1005A which is connected to both the second opening 1102 and the sixth opening 1106. Preferably, the first connecting channel 1001A is formed by the first channel 101A. It is understood that the first connecting channel 1001A may also be a separate channel formed in the valve body 11A and connected to the first opening 1101 and the fifth opening 1105 respectively.

[0124] As shown in the attached image. Figures 11A to 18 As shown, further, when the moving valve plate 122A of the water circuit control valve 10A of the water circuit controller 1A of the water treatment system according to the present utility model embodiment is driven to rotate so that the water circuit control valve 10A is in the bypass working position, the sixth channel 106A of the valve core 12A is connected to the first channel 101A and the fourth channel 104A respectively, so that the raw water can flow from the fifth opening 1105 through the first channel 101A, the sixth channel 106A and the fourth channel 104A to the sixth opening 1106 and be supplied through the sixth connecting pipe 26. That is to say, the sixth channel 106A of the valve core 12A is connected to the first channel 101A and the fourth channel 104A respectively, thereby forming the sixth connecting channel 1006A that is connected to the fifth opening 1105 and the sixth opening 1106 respectively.

[0125] As shown in the attached image. Figures 11A to 18 As shown, preferably, in the water treatment system of this utility model, the first channel 101A of the water control valve 10A of the water controller 1A can be regarded as a through hole extending from the fifth opening 1105 of the valve body 11A to the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A; the second channel 102A is a through hole extending from the second opening 1102 of the valve body 11A to the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A; and the third channel 103A is a through hole extending from the fifth opening 1105 of the valve body 11A to the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A. The third opening 1103 extends to the through hole of the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A. The fourth channel 104A is a through hole extending from the sixth opening 1106 of the valve body 11A to the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A. The fifth channel 105A is a blind hole extending from the second fluid control surface 1220A of the movable valve plate 122A. The sixth channel 106A is a blind hole extending from the second fluid control surface 1220A of the movable valve plate 122A. It can be understood that the fixed valve plate 121A of the valve core 12A of the water circuit control valve 10A of this utility model can be regarded as integrally formed with the valve body 11A. Preferably, the first channel 101A is located at the center of the first fluid control surface 1210A, and the second channel 102A, the third channel 103A and the fourth channel 104A are arranged around the first channel 101A.

[0126] As shown in the attached image. Figure 15A As shown, when the water circuit control valve 10A of the water circuit controller 1A in the water treatment system according to this utility model embodiment is in the series working position, one end of the first fluid control surface 1210A of the fixed valve plate 121A of the fourth channel 104A extending to the valve core 12A is blocked by the moving valve plate 122A. (See attached figures) Figure 15C As shown, when the water control valve 10A of the water controller 1A according to the present utility model embodiment is in the bypass working position, one end of the second channel 102A extending to the first fluid control surface 1210A of the fixed valve plate 121A of the valve core 12A is blocked by the moving valve plate 122A. The fifth channel 105A is connected to the third channel 103A, but an effective water flow path cannot be formed.

[0127] As shown in the attached image. Figures 11A to 18As shown, the water circuit control valve 10A of the water circuit controller 1A in the water treatment system according to an embodiment of the present invention further includes an operating end 123, wherein the operating end 123 is disposed on the outside of the valve core 12A. More specifically, the operating end 123 is disposed on the moving valve plate 122A of the water circuit control valve 10A, so that an operator can drive the moving valve plate 122A of the valve core 12A to rotate relative to the fixed valve plate 121A through the operating end 123.

[0128] As shown in the attached image. Figures 11A to 18 As shown, optionally, when the user rotates the movable valve plate 122A of the valve core 12A to a suitable position via the operating end 123 of the valve core 12A, the water circuit control valve 10A is in the series working position; when the user rotates the movable valve plate 122A of the valve core 12A to another suitable position via the operating end 123 of the valve core 12A, the water circuit control valve 10A is in the parallel working position; when the user rotates the movable valve plate 122A of the valve core 12A to another suitable position via the operating end 123 of the valve core 12A, the water circuit control valve 10A is in the bypass working position.

[0129] Accordingly, in the water treatment system of the present invention, the first opening 1101 and the fifth opening 1105 of the water control valve 10A of the water controller 1A are kept in communication, so that the raw water does not flow through the valve core 12A but flows directly to the first filter element 31. The fourth opening 1104 and the sixth opening 1106 are kept in communication, so that the treated water flowing out of the second filter element 32 does not flow through the valve core 12A but flows directly through the fourth opening 1104 to the sixth opening 1106 and is supplied through the sixth connecting pipe 26. In this water treatment system, the raw water does not flow through the valve core 12A but directly to the first filter element 31. The treated water flowing out of the second filter element 32 does not flow through the valve core 12A but directly to the sixth opening 1106 via the fourth opening 1104. This reduces the structural complexity of the valve core 12A of the water circuit controller 1A and the water circuit control valve 10A in this water treatment system, and reduces the number of through holes in the fixed valve plate 121A and the movable valve plate 122A of the valve core 12A. This allows the valve core 12A to achieve series, parallel, and bypass control of the first filter element 31 and the second filter element 32 using as few through holes as possible. Furthermore, with the reduced number of through holes in the fixed valve plate 121A and the movable valve plate 122A of the valve core 12A, the inner diameter of the through holes in the fixed valve plate 121A and the movable valve plate 122A of the valve core 12A can be increased. Furthermore, since the first opening 1101 and the fifth opening 1105 of the water control valve 10A remain connected, the raw water flows directly to the first filter element 31 through the first opening 1101, and the treated water flowing out of the second filter element 32 flows directly to the sixth opening 1106 through the fourth opening 1104. This allows the inner diameter of the raw water supply channel and the inner diameter of the treated water outflow channel to be set as large as possible, thereby maximizing the raw water inflow rate and the treated water flow rate, and improving the water treatment speed of the entire water treatment system. Finally, when the first filter element 31 and the second filter element 32 are connected in parallel, the raw water of the water treatment system of this invention flows to the second filter element 32 through the first channel 101A, the sixth channel 106A, and the third channel 103A under the control of the valve core 12A, resulting in no water in the valve chamber 110A. This eliminates the need for the sealing component of the moving valve plate 122 in the water control valve 10A.

The sixth connecting pipe 26 is connected to the valve body 11B of the water control valve 10B and to the water supply mechanism, such as the water supply tap of the water treatment system of this utility model (or it can be connected to the filter element outlet port of the softening control valve). In other words, one end of the first connecting pipe 21, one end of the second connecting pipe 22, one end of the third connecting pipe 23, one end of the fourth connecting pipe 24, one end of the fifth connecting pipe 25, and one end of the sixth connecting pipe 26 of the connecting pipe assembly 20 are respectively connected to the valve body 11B. Preferably, the valve core 12B and the valve cavity 110B are respectively arranged to extend linearly, so that the connecting pipe assembly 20 of the water circuit controller 1B can easily connect to the first filter element 31 and the second filter element 32, and also so that the valve core 12B is disposed in the valve cavity 110B and is easy to disassemble and assemble.

The fourth connecting pipe 24 and the sixth connecting pipe 26 are connected through the third connecting channel 1003B, so that the water to be treated (or raw water) can flow from the fifth connecting pipe 25 to the first connecting pipe 21 under water pressure. After the raw water is purified (or softened) by the first filter element 31, the resulting primary treated water flows out through the second connecting pipe 22 and flows to the third connecting pipe 23.

After the water to be treated (or raw water) is purified (or softened) by the first filter element 31 and the second filter element 32 respectively, the resulting treated water flows through the second connecting pipe 22 and the fourth connecting pipe 24 to the sixth connecting pipe 26 and is supplied.

[0137] As shown in the attached image. Figures 19A to 25BAs shown, preferably, in the water treatment system of this utility model, the first channel 101B of the water control valve 10B of the water controller 1B can be regarded as a through hole extending from the fifth opening 1105 of the valve body 11B to the first fluid control surface 1210B of the fixed valve plate 121B of the valve core 12B; the second channel 102B is a through hole extending from the second opening 1102 of the valve body 11B to the first fluid control surface 1210B of the fixed valve plate 121B of the valve core 12B; and the third channel 103B is a through hole extending from the fifth opening 1105 of the valve body 11B to the first fluid control surface 1210B of the fixed valve plate 121B of the valve core 12B. The third opening 1103 extends to a through hole in the first fluid control surface 1210B of the fixed valve plate 121B of the valve core 12B. The fourth channel 104B is a through hole extending from the sixth opening 1106 of the valve body 11B to the first fluid control surface 1210B of the fixed valve plate 121B of the valve core 12B. The fifth channel 105B is a blind hole extending from the second fluid control surface 1220B of the movable valve plate 122B. The sixth channel 106B is a blind hole extending from the second fluid control surface 1220B of the movable valve plate 122B. It can be understood that the fixed valve plate 121B of the valve core 12B of the water circuit control valve 10B of this utility model can be considered as integrally formed with the valve body 11B. Preferably, the third channel 103B is located at the center of the first fluid control surface 1210B, and the first channel 101B, the second channel 102B and the fourth channel 104B are arranged around the third channel 103B.

[0138] As shown in the attached image. Figure 23A As shown, when the water circuit control valve 10B of the water circuit controller 1B of the water treatment system according to the present utility model embodiment is in the series working position, one end of the first fluid control surface 1210B of the fixed valve plate 121B of the first channel 101B extending to the valve core 12B is blocked by the moving valve plate 122B. The fifth channel 105B is connected to the fourth channel 104B, but an effective water flow path cannot be formed.

[0139] As shown in the attached image. Figures 19A to 25B As shown, the water circuit controller 1B of the water treatment system according to an embodiment of the present invention further includes an operating end 123, wherein the operating end 123 is disposed on the outside of the valve core 12B. More specifically, the operating end 123 is disposed on the moving valve plate 122B of the water circuit control valve 10B, so that an operator can drive the moving valve plate 122B of the valve core 12B to rotate relative to the fixed valve plate 121B through the operating end 123.

[0140] As shown in the attached image. Figures 19A to 25BAs shown, optionally, when the user rotates the moving valve plate 122B of the valve core 12B to a suitable position through the operating end 123 of the valve core 12B, the water circuit control valve 10B is in the series working position; when the user rotates the moving valve plate 122B of the valve core 12B to another suitable position through the operating end 123 of the valve core 12B, the water circuit control valve 10B is in the parallel working position. Accordingly, in the water treatment system of the present invention, the first opening 1101 and the fifth opening 1105 of the water control valve 10B of the water controller 1B are kept in communication, so that the raw water does not flow through the valve core 12B but flows directly to the first filter element 31. The fourth opening 1104 and the sixth opening 1106 are kept in communication (if necessary, the fourth connecting pipe 24 and the sixth connecting pipe 24 can be directly connected), so that the treated water flowing out of the second filter element 32 does not flow through the valve core 12B but flows directly through the fourth opening 1104 to the sixth opening 1106 and is supplied through the sixth connecting pipe 26. In this water treatment system, the raw water does not flow through the valve core 12B but directly to the first filter element 31. The treated water flowing out of the second filter element 32 does not flow through the valve core 12B but directly to the sixth opening 1106 via the fourth opening 1104. This reduces the structural complexity of the valve core 12B of the water circuit controller 1B and the water circuit control valve 10B in this water treatment system, and reduces the number of through holes in the fixed valve plate 121B and the movable valve plate 122B of the valve core 12B. This allows the valve core 12B to achieve series and parallel control of the first filter element 31 and the second filter element 32 using as few through holes as possible. Furthermore, with the reduced number of through holes in the fixed valve plate 121B and the movable valve plate 122B of the valve core 12B, the inner diameter of the through holes in the fixed valve plate 121B and the movable valve plate 122B of the valve core 12B can be increased. Furthermore, since the first opening 1101 and the fifth opening 1105 of the water control valve 10B remain connected, the raw water flows directly to the first filter element 31 through the first opening 1101, and the treated water flowing out from the second filter element 32 flows directly to the sixth opening 1106 through the fourth opening 1104. This allows the inner diameter of the raw water supply channel and the inner diameter of the treated water outflow channel to be set as large as possible, thereby maximizing the raw water inflow rate and the treated water flow rate, and improving the water treatment speed of the entire water treatment system.Finally, when the first filter element 31 and the second filter element 32 are connected in parallel, the raw water of the water treatment system of this utility model flows to the second filter element 32 through the first channel 101B, the sixth channel 106B and the third channel 103B under the control of the valve core 12B, so that there is no water in the valve chamber 110B, and the water circuit control valve 10B no longer needs to be installed in the sealing component of the moving valve plate 122.

[0141] As shown in the attached image. Figures 3A to 4E and Figures 8A to 9C , Figures 11A to 12D and Figures 16A to 17C , Figures 19A to 20D and Figures 24A to 25B As shown, in the water treatment system according to this utility model embodiment, the first connecting pipe 21 and the second connecting pipe 22 of the water circuit control valve 10 (or water circuit control valve 10A or water circuit control valve 10B) of the water circuit controller 1 (or water circuit controller 1A or water circuit controller 1B) are disposed on the same side of the valve body 11 (or valve body 11A or valve body 11B) of the water circuit control valve 10 (or water circuit control valve 10A or water circuit control valve 10B). The third connecting pipe 23 and the fourth connecting pipe 24 are disposed on the water circuit control valve 10. On the other side of the valve body 11 (or valve body 11A or valve body 11B) of the water circuit control valve 10A or the water circuit control valve 10B, the fifth connecting pipe 25 and the sixth connecting pipe 26 can be arranged on the same side as the first connecting pipe 21 and the second connecting pipe 22 and located between the first connecting pipe 21 and the second connecting pipe 22, or they can be arranged on the same side as the third connecting pipe 23 and the fourth connecting pipe 24 and located between the third connecting pipe 23 and the fourth connecting pipe 24, so as to make the connection between the raw water inlet and the treated water more convenient.

[0142] It is worth noting that, generally, the first filter element 31 and the second filter element 32 of the water treatment system according to the embodiments of the present invention should be the same (or substantially the same) filter elements to ensure that when the first filter element 31 and the second filter element 32 are arranged in parallel, the purification or softening effect of the two filter elements is the same (or substantially the same), and the service life of the two filter elements is the same (or substantially the same), so that users can replace the first filter element 31 and the second filter element 32 simultaneously (or regenerate the first filter element 31 and the second filter element 32 simultaneously). Furthermore, having the first filter element 31 and the second filter element 32 of the water treatment system according to the embodiments of the present invention as the same (or substantially the same) filter elements also facilitates assembly during production and use and avoids the need for manufacturers to use different production lines to produce the first filter element 31 and the second filter element 32. Accordingly, as shown in the accompanying drawings... Figures 3A to 4E and Figures 8A to 9C, Figures 11A to 12D and Figures 16A to 17C , Figures 19A to 20D and Figures 24A to 25B As shown, in the water treatment system according to this utility model embodiment, the first connecting pipe 21 and the third connecting pipe 23 of the water circuit control valve 10 (or the water circuit control valve 10A or the water circuit control valve 10B) of the water circuit controller 1 (or the water circuit controller 1A or the water circuit controller 1B) are arranged symmetrically (or substantially symmetrically), and the second connecting pipe 22 and the fourth connecting pipe 24 are arranged symmetrically (or substantially symmetrically) to facilitate the installation of two identical or substantially identical first filter element 31 and second filter element 32.

[0143] As shown in the attached image. Figures 1A to 2C As shown, the first filter element 31 of the water treatment system according to this embodiment of the present invention further includes a first filter element cover 41, and the second filter element 32 further includes a second filter element cover 42. The first filter element cover 41 and the second filter element cover 42 are respectively disposed on the first filter element 31 and the second filter element 32, and are interchangeable. In other words, since the first filter element cover 41 and the second filter element cover 42 are interchangeable, even if the first filter element 31 and the second filter element 32 of the water treatment system of the present invention are respectively disposed on both sides of the water circuit control valve 10, when it is necessary to replace the first filter element 31 and the second filter element 32, only one type of filter element needs to be purchased to replace either the first filter element 31 or the second filter element 32, reducing the variety of filter elements to be stocked. Preferably, the first connecting opening 3101 and the second connecting opening 3102 of the first filter element 31 are respectively disposed on the first filter element cover 41, and the first conductive opening 3201 and the second conductive opening 3202 of the second filter element 32 are respectively disposed on the second filter element cover 42.

[0144] As shown in the attached image. Figures 3A to 4E and Figures 8A to 9C , Figures 11A to 12D and Figures 16A to 17C , Figures 19A to 20D and Figures 24A to 25BAs shown, in the water treatment system according to this utility model embodiment, the first connecting pipe 21 and the second connecting pipe 22 of the water circuit control valve 10 (or water circuit control valve 10A or water circuit control valve 10B) of the water circuit controller 1 (or water circuit controller 1A or water circuit controller 1B) are disposed on the same side of the valve body 11 (or valve body 11A or valve body 11B) of the water circuit control valve 10 (or water circuit control valve 10A or water circuit control valve 10B). The third connecting pipe 23 and the fourth connecting pipe 24 are... Located on the same side of the valve body 11 (or valve body 11A or valve body 11B) of the water circuit control valve 10 (or the water circuit control valve 10A or the water circuit control valve 10B), the first filter cover 41 and the second filter cover 42 are optimized so that both sides of the first filter cover 41 or the second filter cover 42 are designed with mounting holes for connecting the water circuit controller 1 (or the water circuit controller 1A or the water circuit controller 1B), thereby making the first filter cover 41 and the second filter cover 42 universal. More specifically, the first connecting opening 3101 and the second connecting opening 3102 of the first filter element 31 are respectively located on the first filter cover 41, and the first conducting opening 3201 and the second conducting opening 3202 of the second filter element 32 are respectively located on the second filter cover 42, and the first filter element 31 and the second filter element 32 are the same (or substantially the same) filter elements, thereby making the first filter cover 41 and the second filter cover 42 interchangeable.

[0145] It is worth noting that, in the water treatment system according to the present invention, the connecting pipe of the water control valve 10 (or the water control valve 10A or the water control valve 10B) of the water controller 1 (or the water controller 1A or the water controller 1B) is integrated into the valve body 11 (or the valve body 11A or the valve body 11B) of the water control valve 10 (or the water control valve 10A or the water control valve 10B). This not only makes the structure of the entire valve more compact and easier to install in a smaller space, but also reduces the pipe layout, shortens the flow path of water in the valve, reduces the resistance of water in the valve, and thus increases the flow rate of water.
