[0042] Refer to the attached diagram in the instruction manual. Figures 1A to 10DThe composite water treatment machine according to an embodiment of the present invention is described, wherein the composite water treatment machine of the present invention includes a control valve 10 and a water treatment device 1, wherein the control valve 10 includes a valve body 11, a valve core 12 and an ejector 13, and the water treatment device 1 includes a purification filter element 21 and a softening filter element 22, wherein the valve body 11 forms a valve cavity 110, an inlet 1104, an outlet 1101, an ejector outlet 1102 and an ejector inlet 1103, the purification filter element 21 has a first connecting opening 2101 and a second connecting opening 2102, and the softening filter element 22 has a first connecting opening 2103. A first through opening 2201 and a second through opening 2202 are provided, wherein the valve core 12 is disposed in the valve cavity 110, wherein the first through opening 2101 of the purification filter element 21 is adapted to be connected to the raw water source, the second through opening 2102 of the purification filter element 21 is connected to the inlet 1104 of the valve body 11, the first through opening 2201 of the softening filter element 22 is connected to the outlet 1101 of the valve body 11, the injection inlet 1301 of the ejector 13 is connected to the injection outlet 1102, and the injection outlet 1302 of the ejector 13 is connected to the injection inlet 1103. Preferably, the inlet 1104 is connected to the valve cavity 110. It can be understood that, although according to the example, the inlet 1104 is disposed in the valve body 11. However, the inlet 1104 may also be located in other positions of the control valve 10, and these should also be considered within the scope of protection of this invention.

[0043] As shown in the attached image. Figures 1A to 3BAs shown, the composite water treatment machine according to an embodiment of the present invention further includes a first adapter 31 and a second adapter 32. The first adapter 31 is disposed between the control valve 11 and the purification filter element 21, and the second adapter 32 is disposed between the control valve 11 and the softening filter element 22. The first adapter 31 forms a raw water channel 3101 and a purified water channel 3102, and the second adapter 32 forms a first water flow channel 3201 and a second water flow channel 3202. The raw water channel 3101 of the first adapter 31 is connected to the first connecting opening 2101 of the purification filter element 21 and the raw water source, respectively. The purified water channel 3102 is connected to the second connecting opening 2102 of the purification filter element 21 and the water inlet 1104 of the valve body 11, respectively. The first water flow channel 3201 of the second adapter 32 is connected to the first conductive opening 2201 of the softening filter element 22 and the outlet 1101 of the valve body 11, respectively. The second water flow channel 3202 of the second adapter 32 is connected to the second conductive opening 2202 of the softening filter element 22. It can be understood that one end of the second water flow channel 3202 of the second adapter 32 is connected to the second conductive opening 2202 of the softening filter element 22, and the other end of the second water flow channel 3202 of the second adapter 32 forms a water supply port or a drain port (in the water treatment working position, the other end of the second water flow channel 3202 forms the water supply port; in the regeneration working position, the other end of the second water flow channel 3202 forms the drain port). Accordingly, the first adapter 31 and the second adapter 32 of the composite water treatment machine of this embodiment enable the entire composite water treatment machine to be easier to install and has a higher degree of integration.

[0044] As shown in the attached image. Figures 1A to 1D As shown, the control valve 10 of the composite water treatment machine according to an embodiment of the present invention is configured to control the flow of water, such as controlling the purified water generated by the purification filter element 21 to be supplied to the softening filter element 22, so that the softening filter element 22 can further soften the purified water generated by the purification filter element 21. Furthermore, the control valve 10, by controlling the flow of the purified water generated by the purification filter element 21 and its supply to the softening filter element 22, also further controls the supply of raw water, such as tap water, to the purification filter element 21 under water pressure. Accordingly, the components of the composite water treatment machine according to this embodiment of the present invention are highly integrated, and the overall structure is simple. It can achieve the purification treatment of raw water, the further softening treatment of purified water, and the regeneration treatment of the softening filter element through a relatively simple structure.

[0045] As shown in the attached image. Figures 1A to 1C , Figure 8A and Figure 8B As shown, the control valve 10 of the composite water treatment machine according to an embodiment of the present invention has a water treatment working position, wherein when the control valve 10 is in the water treatment working position, the valve core 12 of the control valve 10 forms a water treatment channel 10011, wherein the water treatment channel 10011 is connected to the inlet 1104 and the outlet 1101 of the valve body 11 respectively. Accordingly, when the control valve 10 is in the water treatment working position, raw water flows under water pressure through the raw water channel 3101 of the first adapter 31 to the purification filter element 21, and flows into the purification filter element 21 through the first connecting opening 2101. The purified water generated by the purification filter element 21 flows out from the second connecting opening 2102 of the purification filter element 21, and under water pressure, flows through the purified water channel 3102 of the first adapter 31 to the inlet 1104 of the valve body 11 and from the valve body 11 of the control valve 10. The water flows in through the inlet 1104 of component 1, flows through the water treatment channel 10011 to the first water flow channel 3201 of the second adapter 32, and from the first water flow channel 3201 to the first conductive opening 2201 of the softening filter element 22. Then, it flows into the softening filter element 22 from the first conductive opening 2201 and is further softened to generate softened water. Under water pressure, the softened water flows out from the second conductive opening 2202 of the softening filter element 22, and further flows out through the second water flow channel 3202 of the second adapter 32 and is supplied. Accordingly, the raw water is provided to the user after purification and softening treatment. Therefore, when the control valve 10 of the composite water treatment machine according to the embodiment of the present invention is controlled to be in the water treatment working position, the composite water treatment machine of the present invention is controlled to be in its first water treatment working state (or purification-softening water treatment state).

[0046] As shown in the attached image. Figures 1A to 1B , Figure 1D , Figure 9A and Figure 9BAs shown, the control valve 10 of the composite water treatment machine according to an embodiment of the present invention further has a regeneration working position, wherein when the control valve 10 is in the regeneration working position, the valve core 12 of the control valve 10 forms a first regeneration channel 10021 and a second regeneration channel 10022, wherein the first regeneration channel 10021 is connected to the water inlet 1104 and the jet outlet 1102 of the valve body 11, respectively, and the second regeneration channel 10022 is connected to the jet inlet 1103 and the water outlet 1101 of the valve body 11, respectively. Correspondingly, when the control valve 10 is in the regeneration working position, raw water flows under water pressure through the raw water channel 3101 of the first adapter 31 to the purification filter element 21, and flows into the purification filter element 21 through the first connecting opening 2101. The purified water generated by the purification filter element 21 flows out from the second connecting opening 2102 of the purification filter element 21, and under water pressure, flows through the purified water channel 3102 of the first adapter 31 to the inlet 1104 of the valve body 11 and flows in from the inlet 1104 of the valve body 11 of the control valve 10. It flows through the first regeneration channel 10021 to the jet outlet 1102, and then through the jet inlet 1301 of the jet ejector 13. The purified water passes through the jet ejector 13 and mixes with the water from the jet ejector 13. After the regenerated brine is mixed with the brine at the brine inlet 1303 of the ejector 13, it flows to the ejection outlet 1302 of the ejector 13 and then into the ejection inlet 1103. It then flows through the second regeneration channel 10022 to the outlet 1101. The regenerated brine flowing out of the outlet 1101 continues to flow into the first water flow channel 3201 of the second adapter 32, and from the first water flow channel 3201 to the first conductive opening 2201 of the softening filter element 22. It then flows into the softening filter element 22 from the first conductive opening 2201, regenerating the softening resin inside the filter element 22. The generated wastewater, under water pressure, flows out from the second conductive opening 2202 of the softening filter element 22 and is further discharged through the second water flow channel 3202 of the second adapter 32. Correspondingly, the raw water, after purification, is mixed with the regenerated brine to regenerate the softening filter element, and the regenerated wastewater is discharged. Therefore, when the control valve 10 of the composite water treatment machine according to the embodiment of the present invention is controlled to be in the regeneration working position, the composite water treatment machine of the present invention is controlled to be in its regeneration working state.

[0047] As shown in the attached image. Figures 1A to 1DAs shown, the composite water treatment machine according to an embodiment of the present invention further includes a brine tank 40, wherein the brine suction port 1303 of the ejector 13 is connected to the brine chamber 401 of the brine tank 40. It can be understood that the regenerated brine is contained within the brine chamber 401. Preferably, the brine suction port 1303 of the ejector 13 is connected to the brine chamber 401 of the brine tank 40 via a brine pipe 50.

[0048] As shown in Figures 1 to 12 of the attached diagram. Figure 1D , Figure 8A and Figure 8B As shown, according to an embodiment of the present invention, the valve body 11 of the control valve 10 of the composite water treatment machine further has a water inlet 1105, wherein the water inlet 1105 is connected to the brine chamber 401 of the brine tank 40, wherein when the control valve 10 is in the water treatment working position, the valve core 12 of the control valve 10 further forms a water inlet channel 10012, wherein the water inlet channel 10012 is connected to the water inlet 1104 and the water inlet 1105 of the valve body 11 respectively. Correspondingly, when the control valve 10 is in the water treatment working position, the raw water flows to the purification filter element 21 through the raw water channel 3101 of the first adapter 31 under water pressure, and flows into the purification filter element 21 through the first connecting opening 2101. The purified water generated by the purification filter element 21 flows out from the second connecting opening 2102 of the purification filter element 21, and under water pressure, flows to the inlet 1104 of the valve body 11 through the purified water channel 3102 of the first adapter 31 and flows into the valve body 11 through the inlet 1104 of the control valve 10. Part of it flows to the first water flow channel 3201 of the second adapter 32 through the water treatment channel 10011, and part of it flows to the brine tank 40 through the water replenishment channel 10012 to replenish the brine tank 40.

[0049] As shown in Figures 1 to 12 of the attached diagram. Figure 1D As shown, the control valve 10 of the composite water treatment machine according to an embodiment of the present invention further includes a water supply pipe 14 and a float switch 15, wherein the water supply pipe 14 is connected to the water supply port 1105 and the brine chamber 401 respectively, and the float switch 15 is disposed in the brine chamber 401 and is disposed at the communication opening 140 connecting the water supply pipe 14 and the brine tank 40, so that when the water in the brine chamber 401 is replenished with an appropriate amount, it can float up under the buoyancy of the water (or brine) in the brine chamber 401 and block the communication opening 140, so as to prevent further water replenishment and prevent the water in the brine chamber 401 from overflowing.

[0050] As shown in the attached image. Figures 4A to 10DAs shown, the control valve 10 of the composite water treatment machine according to an embodiment of the present invention is a planar valve. The valve core 12 of the planar valve 10 further includes a fixed valve plate 121 and a movable valve plate 122. The fixed valve plate 121 has a first fluid control surface 1210, and the movable valve plate 122 has a second fluid control surface 1220. Both the movable valve plate 122 and the fixed valve plate 121 are disposed in the valve cavity 110. The second fluid control surface 1220 of the movable valve plate 122 is disposed on the first fluid control surface 1210 of the fixed valve plate 121, and the movable valve plate 122 is configured to rotate relative to the fixed valve plate 121. Preferably, the valve cavity 110 of the planar valve 10 is horizontal to facilitate manual operation of the planar valve 10 by the user.

[0051] As shown in the attached image. Figures 4A to 10DAs shown, the planar valve 10 of the composite water treatment machine according to an embodiment of the present invention has a first channel 101, a second channel 102, a third channel 103, a fourth channel 104, and a fifth channel 105. The first channel 101, the second channel 102, and the third channel 103 are respectively disposed on the fixed valve plate 121 and extend from the first fluid control surface 1210 of the fixed valve plate 121. The fourth channel 104 and the fifth channel 105 are respectively disposed on the movable valve plate 122 and extend from the second fluid control surface 1220 of the movable valve plate 122. The first channel 101 is connected to the outlet 1101, the second channel 102 is connected to the jet outlet 1102, the third channel 103 is connected to the jet inlet 1103, and the fourth channel 104 is connected to the inlet 1104. Preferably, the fourth channel 104 is connected to the inlet 1104 through the valve cavity 110. When the movable valve plate 122 rotates relative to the fixed valve plate 121, so that the planar valve 10 is in the water treatment working position, the fourth channel 104 of the planar valve 10 is connected to the first channel 101, thereby forming the water treatment channel 10011, which is connected to the inlet 1104 and the outlet 1101 respectively. Preferably, the fifth channel 105 of the movable valve plate 122 is a blind hole. Furthermore, when the movable valve plate 122 rotates relative to the fixed valve plate 121 so that the planar valve 10 is in the regeneration working position, the fourth channel 104 of the planar valve 10 is connected to the second channel 102, thereby forming the first regeneration channel 10021 which is connected to the inlet 1104 and the jet outlet 1102 respectively. The fifth channel 105 is connected to the first channel 102 and the third channel 103 respectively, thereby forming the second regeneration channel 10022 which is connected to the jet inlet 1103 and the outlet 1101 respectively.

[0052] As shown in the attached image. Figures 4A to 10DAs shown, the planar valve 10 of the composite water treatment machine according to an embodiment of the present invention further has a sixth channel 106, wherein the sixth channel 106 is disposed on the fixed valve plate 121 and extends from the first fluid control surface 1210 of the fixed valve plate 121, and the sixth channel 106 is connected to the water inlet 1105. When the planar valve 10 is in the water treatment working position, the fourth channel 104 of the planar valve 10 is further connected to the sixth channel 106, thereby forming a water replenishment channel 10012 that is connected to the water inlet 1104 and the water replenishment port 1105 respectively. Preferably, the sixth channel 106 is located inside the first channel 101. Further, both the sixth channel 106 and the first channel 101 are located between the second channel 102 and the third channel 103.

[0053] As shown in the attached image. Figures 4A to 10D As shown, when the planar valve 10 is in the water treatment working position, the fifth channel 105 is connected to the second channel 102 and the third channel 103, but not to the fourth channel 104. Therefore, although the fifth channel 105 is connected to the second channel 102 and the third channel 103, since none of the second channel 102, the third channel 103, and the fifth channel 105 are connected to the inlet 1104, a flow channel that allows water to flow cannot be formed. When the planar valve 10 is in the regeneration working position, the sixth channel 106 is closed (or blocked) by the moving valve plate 122.

[0054] As shown in the attached image. Figures 4A to 10D As shown, the fixed valve plate 121 of the valve core 12 of the planar valve 10 of the composite water treatment machine according to an embodiment of the present invention includes a high end portion 1211, a low end portion 1212, and a fixing portion 1213 disposed between the high end portion 1211 and the low end portion 1212. The high end portion 1211 forms the first fluid control surface 1210 of the fixed valve plate 121, and the low end portion 1212 is disposed in the valve cavity 110 of the valve body 11. Preferably, the low end portion 1212 of the fixed valve plate 121 of the valve core 12 of the planar valve 10 of the composite water treatment machine of the present invention is integrally formed and disposed on the inner wall of the valve body 11 of the planar valve 10.

[0055] As shown in the attached image. Figures 4A to 5E As shown, further, in the composite water treatment machine according to the embodiment of the present invention, the inlet 1104, the outlet 1101, the jet outlet 1102, the jet inlet 1103 and the water supply inlet 1105 of the planar valve 10 are formed separately on the valve body 11.

Further, the drive assembly 6 is configured to drive the movable valve plate 122 of the planar valve 10 to rotate relative to the fixed valve plate 121. It is understood that the drive assembly 6 can be any mechanism or component capable of driving the movable valve plate 122 of the planar valve 10 to rotate relative to the fixed valve plate 121. Exemplarily, the drive assembly 6 can be the valve stem 60 for driving the movable valve plate 122 of the planar valve 10 to rotate relative to the fixed valve plate 121. Exemplarily, the drive assembly 6 may also be a gear set for driving the movable valve plate 122 of the planar valve 10 to rotate relative to the fixed valve plate 121. The gear set includes a driving gear and driven teeth disposed on the sidewall of the movable valve plate 122. The driving gear meshes with the driven teeth of the movable valve plate 122, allowing a user or operator to drive the movable valve plate 122 to rotate relative to the fixed valve plate 121 by rotating the driving gear. Exemplarily, the drive assembly 6 may also include a drive rod disposed on the movable valve plate 122 of the planar valve 10 and parallel to the second fluid control surface 1220 of the movable valve plate 122. The user can drive the movable valve plate 122 to rotate relative to the fixed valve plate 121 via the drive rod of the drive assembly 6, thereby controlling the planar valve 10 to be in a corresponding operating position.
