Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a control valve core for a water softener. Background Technology

[0002] With the steady improvement of residents' living standards, their attention to the quality of domestic drinking water is also increasing. Northern my country has long suffered from high water hardness, leading to a surge in popularity of water softeners in recent years. Generally, water softeners operate in four main modes: normal operation, water replenishment, backwashing, forward washing, and regeneration. When a water softener operates in different modes, the internal water circuits need to be switched accordingly to ensure unobstructed flow. The control valve is the core component that controls the flow of water in these different modes. However, traditional water softener control valves are bulky and complex, resulting in large valve heads that are difficult to install in many homes, indicating room for improvement. Utility Model Content

[0014] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0015] This utility model relates to a control valve core for a water softener, as shown in... Figure 1 As shown, the system includes a valve housing 10, a rotating shaft 20, a ceramic moving plate 30, and a water outlet module. The valve housing 10 is a cylindrical structure with an open lower end and at least one water inlet 11 on its peripheral wall. The water outlet module is fixedly installed inside the port of the valve housing 10, and its internal structure has six independent water outlet channels. The ceramic moving plate 30 is movably fitted onto the upper surface of the water outlet module. The outer edge of the ceramic moving plate 30 has a flow notch 31, and the lower surface has a first guide groove 32 and a second guide groove 33 extending from the inside to the outside. The rotating shaft 20 is linked to the ceramic moving plate 30 to drive the ceramic moving plate 30 to rotate. By adjusting the relative position between the ceramic moving plate 30 and the water outlet module, the selection between the water inlet 11 and the water outlet channel, as well as between the water outlet channels, is controlled, so that the valve core can be freely controlled to switch between normal operation, water replenishment, backwashing, forward washing, and regeneration states.

[0016] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, the first guide groove 32 on the ceramic moving plate 30 extends through the rotation center; the six water outlet channels of the water outlet module have an inlet hole 41, an outer hole 42, an inner hole 43, a drain hole 44, a salt hole 1 45, and a salt hole 2 46 formed on the upper end face, wherein the drain hole 44 is set corresponding to the rotation center of the ceramic moving plate 30, and the upper end face of the water outlet module is recessed with a first guide groove 47 and a second guide groove 48 passing through the outer hole 42 and the salt hole 2 46 respectively; the six water outlet channels of the water outlet module have outlets formed on their lower end faces. The first water outlet 61, the second water outlet 62, the third water outlet 63, the fourth water outlet 64, the fifth water outlet 65, and the sixth water outlet 66 are respectively connected to the perforation hole 41, the outer hole 42, the inner hole 43, the drain hole 44, the salt hole 1 45, and the salt hole 2 46. The first water outlet 61 and the fifth water outlet 65 are used to connect to the jet injector, the second water outlet 62 is used to connect to the resin tank, the third water outlet 63 is used to connect to the central pipe, the fourth water outlet 64 is used to connect to the drain pipe, and the sixth water outlet 66 is used to connect to the salt tank.

[0017] In this embodiment, as Figure 2 , Figure 3 ,as well as Figures 8-12 As shown, the inner end of the inner hole 43, the first salt hole 45, and the first guide groove 47 are all located within the circular area swept by the rotation of the first guide groove 32. The extension line of the second guide groove 33 passes through the rotation center of the ceramic moving plate 30. The second guide groove 48 is located radially outside the first salt hole 45. The outer end of the injection hole 41, the first guide groove 47, and the second guide groove 48 are all located within the annular area swept by the rotation of the flow gap 31. Through the above scheme, the first guide groove 32 can make the discharge hole 44 connected to the inner hole 43, the first salt hole 45, or the outer hole 42, or not connected at all. The second guide groove 33 can make the first salt hole 45 connected to the second salt hole 46, or not connected. The flow gap 31 is connected to the injection hole 41, the outer hole 42, or the second salt hole 46. At the same time, through reasonable arrangement, the valve core can reliably switch between various states.

[0018] When the valve core is as Figure 8 When in normal working condition, there is no water flow inside the valve core, and the water softener is in its initial state (normal working, standby, or off state).

[0019] When the valve core is as Figure 9 When in the water replenishment state, the flow gap 31 connects the water inlet 11 and the salt two-hole 46. At this time, the water softener is in the water replenishment state: tap water can flow into the salt tank through the water inlet 11 → flow gap 31 → salt two-hole 46 to replenish the salt tank.

[0020] When the valve core is as Figure 10When in backwash mode, the first guide groove 32 connects the drain hole 44 and the first guide groove 47 (outer hole 42). At this time, the water softener is in backwash mode: tap water enters from the central pipe, flows out from the resin tank side, enters the drain hole 44 through the outer hole 42, and is discharged from the drain pipe (the water inlet is on the other side). Figure 10 (Not reflected in the text).

[0021] When the valve core is as Figure 11 When in regeneration mode, the flow gap 31 connects the inlet 11 and the ejector 41, the first guide groove 32 connects the drain hole 44 and the first guide groove 47 (outer hole 42), and the second guide groove 33 connects the salt hole 45 and the second guide groove 48 (salt hole 46). At this time, the water softener is in regeneration mode: since the ejector 41 and the salt hole 45 are both connected to the ejector, the high-concentration brine in the brine tank is drawn up through the salt hole 46 and the salt hole 45 to mix with the inlet water and dilute it into a lower concentration brine. The mixed brine enters the resin tank from the central pipe, and after regenerating the resin, it enters the drain hole 44 through the outer hole 42 and is discharged from the drain pipe.

[0022] When the valve core is as Figure 12 When in the forward washing state, the flow gap 31 connects the water inlet 11 and the first guide groove 47 (outer hole 42), and the first guide groove 32 connects the drain hole 44 and the inner hole 43. At this time, the water softener is in the forward washing state: tap water enters the resin tank from the outer hole 42, passes through the central pipe, and wastewater enters the drain hole 44 through the inner hole 43 and is discharged from the drain pipe.

[0023] In this embodiment, as Figures 1 to 7 As shown, the water outlet module specifically includes a first ceramic plate 40, a second ceramic plate 50, and a base 60, which are sequentially positioned and connected from top to bottom. Preferably, sealing elements are provided between the first ceramic plate 40 and the second ceramic plate 50, and between the second ceramic plate 50 and the base 60, to ensure the sealing of each water outlet channel. A perforation hole 41, an outer hole 42, an inner hole 43, a drain hole 44, a salt outlet hole 1 45, and a salt outlet hole 2 46 are provided on the first ceramic plate 40. The first to sixth water outlet holes 66 are provided on the base 60. The second ceramic plate 50 is provided with a first through hole 51, a second through hole 52, a third through hole 53, a fourth through hole 54, a fifth through hole 55, and a sixth through hole 56, respectively corresponding to the six holes on the first ceramic plate 40 and the six holes on the base 60. Preferably, A flow guiding structure is provided between the first ceramic plate 40 and the second ceramic plate 50, and between the second ceramic plate 50 and the base 60, to enable at least one set of corresponding holes to be staggered and connected. The flow guiding structure includes a flow guiding groove 7 disposed on at least one end face and passing through the hole. Through the hole displacement effect of the flow guiding structure, the first to sixth water outlet holes 66 can be evenly spaced around the outer edge of the base 60 to facilitate the connection of the water outlet holes with other components.

[0024] In this embodiment, as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the first ceramic fixing plate 40 and the second ceramic fixing plate 50 are connected by positioning protrusions and positioning holes, and the second ceramic fixing plate 50 is connected to the base 60 by positioning protrusions and positioning holes. Specifically, the lower surface of the first ceramic fixing plate 40 is provided with a plurality of first positioning holes 49 along its outer edge, and the upper surface of the second ceramic fixing plate 50 is provided with a corresponding first positioning protrusion 57 that fits into the first positioning holes 49. Thus, the first positioning holes 49 and the first positioning protrusion 57 are used to achieve the positioning connection between the first ceramic fixing plate 40 and the second ceramic fixing plate 50. The lower surface of the second ceramic fixing plate 50 is provided with a plurality of second positioning holes 58 along its outer edge, and the upper surface of the base 60 is provided with a corresponding second positioning protrusion 68 that fits into the second positioning holes 58. The second positioning protrusion 68 and the second positioning holes 58 are used to achieve the positioning connection between the second ceramic fixing plate 50 and the base 60.

[0025] In this embodiment, as Figure 1 and Figure 7 As shown, the base 60 is provided with a number of snap fasteners 67 that extend into the valve housing 10 at intervals around its circumference. The valve housing 10 is provided with corresponding slots 13 that cooperate with the snap fasteners 67. In this way, the base 60 and the valve housing 10 are connected by the cooperation of the snap fasteners 67 and the slots 13.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a through hole 12 is provided at the central axis of the upper end face of the valve housing 10. The rotating shaft 20 includes a linkage part 22 located inside the valve housing 10 and linked to the ceramic moving plate 30, and a shaft part 21 connected to the linkage part 22 and passing through the through hole 12 to the outside of the valve housing 10. The shaft part 21 is used to connect to an external power component to drive the ceramic moving plate 30 to rotate and adjust the relative position between it and the first ceramic fixed plate 40. Preferably, a sealing ring is provided between the shaft part 21 and the through hole 12 to ensure the sealing between the two. Specifically, a plurality of linkage protrusions 221 are provided on the linkage part 22, and linkage ports 34 that fit into the linkage protrusions 221 are correspondingly provided on the upper surface of the ceramic moving plate 30. Thus, the linkage between the rotating shaft 20 and the ceramic moving plate 30 is realized through the cooperation of the linkage protrusions 221 and the linkage ports 34.

[0027] Compared with the prior art, the valve core structure of this utility model is simple and ingenious, with fewer core components, low manufacturing and maintenance costs, and a simple production and assembly process.

Furthermore, the valve core is easy to control; simply adjusting the rotation angle of the shaft is sufficient to control the valve core to switch between different working states.

[0028] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
