Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically providing an integrated water purifier and softener. Background Technology

[0002] Currently, household water purification equipment and water softening equipment are usually two separate devices.

[0003] In existing technologies, if a user has both purified and softened water needs, a separate water purifier and a separate water softener must be purchased and installed. However, the installation space in typical residential kitchen sink areas is generally quite limited, making it difficult to accommodate two devices simultaneously. This prevents users from obtaining both purified and softened water at the same point of use. Furthermore, each device has its own independent inlet and outlet water pipes, requiring separate connections to the water source and faucet during installation. This cumbersome process, coupled with numerous exposed and cluttered pipes, increases installation difficulty and the risk of leaks. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to at least a certain extent solve the problems in the prior art that require the separate installation of water purifiers and water softeners when there are simultaneous needs for water purification and water softening, resulting in insufficient installation space, complex pipe connections, and high risk of leakage.

[0005] In a first aspect, this utility model provides an integrated water purifier and softener, comprising: a purification tank having a raw water inlet, a purified water outlet, and a softened water outlet; the purification tank having a raw water channel and a purified water channel, and a purified water outlet port; the raw water channel communicating with the raw water inlet, and the purified water channel communicating with the purified water outlet and / or the purified water outlet port; a softening tank having a softened water inlet port and a softened water outlet port; and a control valve assembly having an inlet flow channel and an outlet flow channel. The valve assembly includes a first control valve and a second control valve. The first control valve has a first flow channel and a second flow channel, and the second control valve has a third flow channel and a fourth flow channel. The first flow channel and the third flow channel are connected and can form the inlet flow channel. The second flow channel and the fourth flow channel are connected and can form the outlet flow channel. The control valve assembly is configured to allow the purified water outlet port to be connected to the softened water inlet port through the inlet flow channel, and to allow the softened water outlet port to be connected to the softened water outlet through the outlet flow channel.

[0006] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the first control valve further has a first interface and a second interface, and the second control valve further has a third interface and a fourth interface; the first interface is connected to the purified water outlet port, the third interface is connected to the softened water inlet port, and the first interface is connected to the third interface through the first flow channel and the third flow channel in sequence to form the water inlet channel; the second interface is connected to the softened water outlet, the fourth interface is connected to the softened water outlet port, and the second interface is connected to the fourth interface through the second flow channel and the fourth flow channel in sequence to form the water outlet channel.

[0007] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the first control valve includes a first housing and a first switching component disposed within the first housing. The first switching component is configured to allow the first interface to selectively communicate with either the first flow channel or the second flow channel.

[0008] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the first housing is further provided with a jet inlet suitable for communication with the inlet of the jet injector and a jet outlet suitable for communication with the outlet of the jet injector. The first switching component is further configured to enable the first interface to selectively communicate with the jet inlet and the jet outlet to selectively communicate with the second flow channel.

[0009] In the preferred technical solution of the above-mentioned integrated water purifier and softener, the integrated water purifier and softener further includes an ejector and a salt tank. The inlet end of the ejector is connected to the jet inlet, and the outlet end of the ejector is connected to the jet outlet. The ejector is also provided with a salt suction port, which is connected to the salt tank.

[0010] In the preferred technical solution of the above-mentioned integrated water purifier and softener, the first switching component includes a first fixed plate, a first movable plate, and a first driving mechanism. The first fixed plate is provided with a plurality of first fixed channels, and the first movable plate is provided with a plurality of first movable channels. The first driving mechanism is drivenly connected to the first movable plate to drive the first movable plate to rotate relative to the first fixed plate, so that at least one of the first movable channels overlaps with at least one of the first fixed channels.

[0011] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the second control valve includes a second housing and a second switching component disposed within the second housing. The second switching component is configured to allow the third interface to selectively communicate with the third flow channel and the fourth interface to selectively communicate with the fourth flow channel.

[0012] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the second housing is further provided with a wastewater interface, and the second switching component is further configured to enable the third interface or the fourth interface to communicate with the wastewater interface.

[0013] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the second switching component includes a second fixed plate, a second movable plate, and a second driving mechanism. The second fixed plate is provided with a plurality of second fixed channels, and the second movable plate is provided with a plurality of second movable channels. The second driving mechanism is drivenly connected to the second movable plate to drive the second movable plate to rotate relative to the second fixed plate, so that at least one of the second movable channels overlaps with at least one of the second fixed channels.

[0014] In the preferred embodiment of the above-mentioned integrated water purifier and softener, the raw water inlet, the purified water outlet, and the softened water outlet are spaced apart along a first direction, and the axes of the raw water inlet, the purified water outlet, and the softened water outlet are parallel to each other, wherein the first direction is perpendicular to the central axis of the purification tank.

[0015] By adopting the above technical solution, a control valve assembly connects the purification tank and the softening tank into a single unit. This allows purified water from the purification tank to be transported through the inlet channel of the control valve assembly to the softening tank for softening treatment. The softened water from the softening tank is then transported through the outlet channel of the control valve assembly to the soft water outlet on the purification tank. This integrates the water purification and softening functions into one unit, achieving the goal of providing both purified and softened water in a single device. There is no need to purchase and install separate water purification and softening equipment, reducing equipment costs and installation space requirements. Furthermore, by placing the raw water inlet, purified water outlet, and softened water outlet all on the purification tank, the purification tank simultaneously serves as both a water treatment and water distribution hub, significantly reducing the number of exposed pipes and joints, resulting in a more compact structure and effectively reducing the risk of leakage. All external pipes only need to be centrally connected to one side of the purification tank, making installation more convenient. In addition, the water purification channel is connected to the water purification outlet and / or the purified water outlet port, allowing users to take purified water, soft water, or both as needed, making the usage flexible and diverse and meeting the water needs of different living scenarios.

[0016] Furthermore, by setting the control valve group as a split dual-valve structure consisting of a first control valve and a second control valve, and connecting the first control valve and the second control valve to the purification tank and the softening tank respectively through their respective interfaces, the inlet flow channel is formed by sequentially connecting the first flow channel of the first control valve and the third flow channel of the second control valve, and the outlet flow channel is formed by sequentially connecting the second flow channel of the first control valve and the fourth flow channel of the second control valve, thus realizing the separation and independent control of the transport path of purified water from the purification tank to the softening tank and the return path of softened water from the softening tank back to the softened water outlet on the purification tank.

[0017] Furthermore, by configuring the first control valve to include a housing and a first switching component, and enabling the first switching component to selectively connect the first interface to either the first flow channel or the second flow channel, the flow direction switching function of purified water after flowing out of the purification tank is realized. When the first interface is connected to the first flow channel, the purified water flows to the softening tank through the inlet flow channel for softening treatment; when the first interface is connected to the second flow channel, the purified water flows in the opposite direction through the outlet flow channel, thereby facilitating the entry of purified water from the fourth interface through the softened water outlet port into the softening tank for backwashing. The configuration of the first switching component allows the first control valve to flexibly switch the flow direction of the purified water, thereby realizing the switching of different working modes. The structure is simple and the control is reliable.

[0018] Furthermore, by setting a jet inlet and a jet outlet on the first housing, and enabling the first switching component to connect the first interface to the jet inlet and the second flow channel to the jet outlet, in regeneration mode, purified water from the purification tank can enter the jet injector through the jet inlet. The jet injector uses the jet principle to generate negative pressure at the brine suction port, sucking in the brine in the brine tank and mixing it to form regenerated brine, which is then sent to the softening tank through the jet outlet and the second flow channel to regenerate the resin. This structure realizes the use of purified water produced by the equipment itself for jet brine suction regeneration, without the need for an additional regeneration water pump or external regeneration water source, simplifying the equipment structure and reducing manufacturing costs.

[0019] Furthermore, by configuring the second control valve to include a second housing and a second switching component disposed within the second housing, and enabling the second switching component to selectively connect the third interface to the third flow channel and the fourth interface to the fourth flow channel, the second control valve achieves the function of controlling the inlet and outlet water of the softening tank. In water production mode, purified water enters the softening tank through the inlet flow channel and the third interface for softening treatment, and the softened water enters the outlet flow channel through the fourth interface and flows back to the soft water outlet. In forward or reverse washing mode, the direction of water flow can be changed by switching to achieve forward or reverse washing of the resin inside the softening tank.

[0020] Furthermore, by setting a wastewater interface on the second housing and enabling the second switching component to connect the third or fourth interface to the wastewater interface, the rinsing water can be directly guided to the wastewater interface for discharge in forward washing mode, backwashing mode, and regeneration mode. This achieves efficient discharge of softening tank cleaning wastewater. At the same time, the wastewater discharge function is integrated into the second control valve, eliminating the need for an additional independent sewage pipe, simplifying the water circuit layout of the equipment, avoiding cross-contamination between cleaning wastewater and product water circuits, and improving the quality of effluent and the hygiene and safety of the system.

[0021] Furthermore, by setting the raw water inlet, purified water outlet, and soft water outlet with parallel axes, all external pipelines can be led out in the same direction, resulting in neat pipeline routing. This avoids pipeline crossings or interference, significantly improving the equipment's adaptability to installation in confined spaces (such as under-sink spaces). Installers no longer need to operate in multiple different directions when connecting pipelines; they only need to complete the connection of all pipelines on the same side of the purification tank, effectively improving installation efficiency and maintenance convenience.

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] It should be noted that in the description of this utility model, terms such as "upper" and "lower," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figures 1 to 4 As shown, the integrated water purifier and softener of this utility model includes a purification tank 2, a softening tank 3, and a control valve assembly. The purification tank 2 has a raw water inlet 21, a purified water outlet 22, and a softened water outlet 23. The purification tank 2 is provided with a raw water channel 241 and a purified water channel 242 (e.g., ...). Figure 15 As shown), the purification tank 2 is also provided with a purified water outlet port 25. The raw water channel 241 is connected to the raw water inlet 21, and the purified water channel 242 is connected to the purified water outlet 22 and / or the purified water outlet port 25. The softening tank 3 has a softened water inlet port 31 and a softened water outlet port 32. The control valve group has an inlet flow channel and an outlet flow channel. The control valve group includes a first control valve 4 and a second control valve 5. The first control valve 4 has a first flow channel 413 and a second flow channel 414. The second control valve 5 has a third flow channel 513 and a fourth flow channel 514. The first flow channel 413 and the third flow channel 513 are connected and can form an inlet flow channel. The second flow channel 414 and the fourth flow channel 514 are connected and can form an outlet flow channel. The control valve group is configured to allow the purified water outlet port 25 to be connected to the softened water inlet port 31 through the inlet flow channel, and to allow the softened water outlet port 32 to be connected to the softened water outlet 23 through the outlet flow channel.

[0028] By setting up a control valve assembly, the purification tank 2 and the softening tank 3 are connected as a whole. The purified water from the purification tank 2 can be transported to the softening tank 3 through the inlet channel of the control valve assembly for softening treatment. The softened water from the softening tank 3 is then transported to the soft water outlet 23 on the purification tank 2 through the outlet channel of the control valve assembly. This integrates the water purification and softening functions into one unit, achieving the goal of providing both purified and softened water in a single device. There is no need to purchase and install separate water purification and softening equipment, reducing equipment costs and installation space requirements. Furthermore, by placing the raw water inlet 21, purified water outlet 22, and soft water outlet 23 all on the purification tank 2, the purification tank 2 simultaneously serves as both a water treatment and water distribution hub, significantly reducing the number of exposed pipes and joints, resulting in a more compact structure and effectively reducing the risk of leakage. All external pipes only need to be centrally connected to one side of the purification tank 2, making installation more convenient.

[0029] Furthermore, the water purification channel 242 is connected to the water purification outlet 22 and / or the purified water outlet port 25, allowing users to access purified water, softened water, or both simultaneously as needed. This flexible usage method meets the water needs of different living scenarios. It is understood that the water purification channel 242 can be configured to connect only to the water purification outlet 22, allowing purified water from the purification tank 2 to be output through the outlet 22 for user access. Alternatively, the water purification channel 242 can be configured to connect only to the purified water outlet port 25, allowing purified water from the purification tank 2 to flow into the first control valve for softening or for forward / backwashing or regeneration of the softening tank. Furthermore, the water purification channel 242 can be configured to connect to both the water purification outlet 22 and the purified water outlet port 25 simultaneously, enabling water softening or for forward / backwashing or regeneration of the softening tank while simultaneously outputting purified water. Those skilled in the art can adjust this configuration according to actual needs.

[0030] It should be noted that, in practical applications, those skilled in the art can set the specific type of control valve assembly without any limitation, as long as it has an inlet channel and an outlet channel, and the control valve assembly is set so that the purified water outlet port 25 is connected to the softened water inlet port 31 through the inlet channel, and the softened water outlet port 32 is connected to the softened water outlet 23 through the outlet channel.

[0031] Preferably, such as Figures 2 to 3 , Figures 5 to 7As shown, the first control valve 4 also has a first interface 411 and a second interface 412, and the second control valve 5 also has a third interface 511 and a fourth interface 512; the first interface 411 is connected to the purified water outlet port 25, and the third interface 511 is connected to the softened water inlet port 31. The first interface 411 is connected to the third interface 511 through the first flow channel 413 and the third flow channel 513 in sequence to form an inlet flow channel; the second interface 412 is connected to the softened water outlet 23, and the fourth interface 512 is connected to the softened water outlet port 32. The second interface 412 is connected to the fourth interface 512 through the second flow channel 414 and the fourth flow channel 514 in sequence to form an outlet flow channel.

[0032] By setting the control valve group as a split dual-valve structure consisting of a first control valve 4 and a second control valve 5, and connecting the first control valve 4 and the second control valve 5 to the purification tank 2 and the softening tank 3 respectively through their respective interfaces, the water inlet channel is formed by sequentially connecting the first flow channel 413 of the first control valve 4 and the third flow channel 513 of the second control valve 5, and the water outlet channel is formed by sequentially connecting the second flow channel 414 of the first control valve 4 and the fourth flow channel 514 of the second control valve 5. This achieves the separation and independent control of the transport path of purified water from the purification tank 2 to the softening tank 3 and the return path of softened water from the softening tank 3 back to the softened water outlet 23 on the purification tank 2.

[0033] Preferably, such as Figure 6 and Figure 7 As shown, the first control valve 4 is also provided with a first connection port 416 communicating with the first flow channel 413 and a second connection port 417 communicating with the second flow channel 414. The second control valve 5 is also provided with a third connection port 516 communicating with the third flow channel 513 and a fourth connection port 517 communicating with the fourth flow channel 514. The first connection port 416 is connected to the third connection port 516, and the second connection port 417 is connected to the fourth connection port 517.

[0034] Preferably, such as Figure 14 and Figure 15 As shown, the purification tank 2 is equipped with a purification filter element 27 and a first central tube 28 disposed within the purification filter element 27. A raw water channel 241 is formed between the inner wall of the purification tank 2 and the purification filter element 27, and a purified water channel 242 is formed within the first central tube 28. The softening tank 3 is equipped with an upper water distributor 351, a lower water distributor 352, and a second central tube 34 disposed between the upper water distributor 351 and the lower water distributor 352. Resin is arranged between the upper water distributor 351 and the lower water distributor 352.

[0035] like Figure 4 As shown, the purification tank 2 is also provided with a purification connection port 26. The second interface 412 of the first control valve 4 is connected to the purification connection port 26, and the second interface 412 is connected to the soft water outlet 23 through the purification connection port 26.

[0036] Preferably, such as Figure 6 and Figure 8 As shown, the first control valve 4 includes a first housing 41 and a first switching component 42 disposed within the first housing 41. The first switching component 42 is configured to allow the first interface 411 to selectively communicate with either the first flow channel 413 or the second flow channel 414.

[0037] By configuring the first control valve 4 to include a housing and a first switching component 42, and enabling the first switching component 42 to selectively connect the first interface 411 to the first flow channel 413 or the second flow channel 414, the flow direction switching function of purified water after flowing out of the purification tank 2 is realized. When the first interface 411 is connected to the first flow channel 413, the purified water flows through the inlet flow channel to the softening tank 3 for softening treatment or for backwashing the softening tank 3. When the first interface 411 is connected to the second flow channel 414, the purified water flows in the reverse direction through the outlet flow channel, thereby facilitating the entry of purified water from the fourth interface 512 into the softening outlet port 32, so as to backwash the softening tank 3. The configuration of the first switching component 42 enables the first control valve 4 to flexibly switch the flow direction of purified water, thereby realizing the switching of different working modes. The structure is simple and the control is reliable.

[0038] More preferably, such as Figures 16 to 17 , Figure 19 , Figures 21 to 26 , Figure 31 and Figure 32 As shown, a first water cavity 4151 is also provided inside the first housing 41. The first interface 411 is connected to the first water cavity 4151. The first water cavity 4151 can be selectively connected to the first flow channel 413 or the second flow channel 414.

[0039] Preferably, such as Figure 5 and Figure 6 As shown, the first housing 41 is also provided with a jet inlet 441 for communicating with the inlet of the jet injector and a jet outlet 442 for communicating with the outlet of the jet injector. The first switching component 42 is also configured to allow the first interface 411 to selectively communicate with the jet inlet 441 and the jet outlet 442 to selectively communicate with the second flow channel 414.

[0040] By setting a jet inlet 441 and a jet outlet 442 on the first housing 41, and enabling the first switching component 42 to connect the first interface 411 to the jet inlet 441 and the second flow channel 414 to the jet outlet 442, in regeneration mode, purified water from the purification tank 2 can enter the ejector through the jet inlet 441. The ejector uses the jet principle to generate negative pressure at the brine inlet, drawing in the brine in the brine tank and mixing it to form regenerated brine, which is then sent to the softening tank 3 through the jet outlet 442 and the second flow channel 414 to regenerate the resin. This structure realizes the use of purified water produced by the equipment itself for jet brine regeneration, without the need for an additional regeneration water pump or external regeneration water source, simplifying the equipment structure and reducing manufacturing costs.

[0041] Specifically, such as Figures 25 to 29 As shown, the first housing 41 is also provided with a third water cavity 4152 and a fourth water cavity 4153. The jet inlet 441 is connected to the third water cavity 4152, and the jet outlet 442 is connected to the fourth water cavity 4153.

[0042] It should be noted that the method of providing a jet inlet 441 and a jet outlet 442 on the first housing 41 to achieve salt absorption during the regeneration process is not limited to this. For example, a jet inlet 441 and a jet outlet 442 can also be provided on the second housing 51 to achieve salt absorption during the regeneration process. Alternatively, a jet outlet 442 can be directly provided on the softening tank 3, allowing the brine to flow directly into the softening tank 3 through the jet outlet 442. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model. Of course, it is preferable to provide a jet inlet 441 and a jet outlet 442 on the first housing 41 to achieve salt absorption during the regeneration process.

[0043] Preferably, the integrated water purifier and softener also includes an ejector and a brine tank (not shown in the figure). The inlet end of the ejector is connected to the ejector inlet 441, and the outlet end of the ejector is connected to the ejector outlet 442. The ejector is also provided with a brine suction port, which is connected to the brine tank.

[0044] By setting up an ejector and connecting its inlet to the ejector inlet 441, its outlet to the ejector outlet 442, and its brine suction port to the brine tank, a complete jet regeneration circuit is formed. When purified water enters the ejector through the ejector inlet 441, a negative pressure is generated at the brine suction port to automatically draw salt solution from the brine tank. After mixing to form regenerated brine, it is sent back to the flow channel of the first control valve 4 through the ejector outlet 442, and finally enters the softening tank 3 to regenerate the resin. This jet regeneration structure can achieve automatic brine suction without an external power source, has high regeneration efficiency, low operating costs, and is simple in structure, has a low failure rate, and is easy to maintain.

[0045] Preferably, such as Figure 8 , Figures 10 to 11As shown, the first switching component 42 includes a first fixed plate 422, a first movable plate 421, and a first driving mechanism. The first fixed plate 422 is provided with a plurality of first fixed channels, and the first movable plate 421 is provided with a plurality of first movable channels. The first driving mechanism is drivenly connected to the first movable plate 421 to drive the first movable plate 421 to rotate relative to the first fixed plate 422, so that at least one of the first movable channels overlaps with at least one of the first fixed channels.

[0046] By configuring the first switching component 42 into a structure that includes a first fixed plate 422 and a first moving plate 421 cooperating, the fixed plate is provided with multiple fixed channels, and the moving plate is provided with multiple moving channels. The moving plate is driven to rotate relative to the fixed plate by the first driving mechanism, so that the moving channels and the fixed channels form different overlapping cooperation relationships at different angles, thereby realizing the switching of different water channels.

[0047] Specifically, such as Figure 11 As shown, the first moving channel includes a first through hole 4211, a second through hole 4212, a first water tank 4214, and a second water tank 4213. The first through hole 4211 and the second through hole 4212 penetrate the first moving piece 421 along the axial direction of the first moving piece 421. The first water tank 4214 and the second water tank 4213 are both located on the side of the first moving piece 421 close to the first fixed piece and do not penetrate the first moving piece 421.

[0048] like Figure 10 As shown, the first fixed channel includes a first water passage 4221, a second water passage 4222, a third water passage 4223, a fourth water passage 4224, and a fifth water passage 4225. The first water passage 4221, the second water passage 4222, the third water passage 4223, the fourth water passage 4224, and the fifth water passage 4225 all penetrate the first fixed plate 422 along the axial direction of the first fixed plate 422.

[0049] It should be noted that the first switching component 42 is not limited to including a first fixed plate 422, a first movable plate 421, and a first driving mechanism. For example, the first switching component 42 can also be configured as a piston-type switching structure, where the water path switching is achieved through the reciprocating linear motion of one or more pistons within the valve body; or, the first switching component 42 can be configured as a valve core rotational switching structure, where the water path switching is achieved through the rotational motion of a valve core with channels within the valve body. Such adjustments and changes to the specific configuration of the first switching component 42 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model. Of course, preferably, the first switching component 42 is configured to include a first fixed plate 422, a first movable plate 421, and a first driving mechanism to achieve water path switching.

[0050] It should also be noted that those skilled in the art can configure the first drive mechanism to include only the first drive component 4231, or the first drive mechanism can be configured to include both the first drive component 4231 and the first transmission component 4232. Such adjustments and changes to the specific configuration of the first drive mechanism do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model.

[0051] Preferably, such as Figure 8 As shown, the first driving mechanism includes a first driving component 4231 and a first transmission component 4232. The first driving component 4231 is driven to be connected to the first moving piece 421 through the first transmission component 4232.

[0052] By setting the first drive mechanism as a combination of the first drive component 4231 and the first transmission component 4232, the first drive component 4231 transmits power to the first moving plate 421 through the first transmission component 4232. The type of the first drive component 4231 (such as a motor, a geared motor, etc.) and the transmission method (such as gear transmission, worm gear transmission, etc.) can be flexibly selected according to actual needs, which improves the adaptability of the control valve to different application scenarios and the controllability of the drive precision.

[0053] It is understood that those skilled in the art can configure the first driving component 4231 as a stepper motor, or as a geared motor, or as any other possible motor type. Those skilled in the art can make flexible choices according to actual needs.

[0054] It should be noted that this utility model does not limit the specific configuration type of the first transmission component 4232. For example, the first transmission component 4232 can be configured as a gear transmission, or it can be configured as a worm gear transmission. Such adjustments and changes to the specific configuration type of the first transmission component 4232 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0055] Preferably, such as Figure 8 As shown, the first transmission component 4232 includes a first transmission shaft 42321, a first gear 42322, and a second gear 42323. The first gear 42322 is connected to the output end of the motor, and the second gear 42323 is connected to the first moving plate 421 through the first transmission shaft 42321. The first gear 42322 and the second gear 42323 mesh with each other.

[0056] Specifically, such as Figure 5 and Figure 6As shown, the first control valve 4 also includes a first mounting plate 43, which is fixedly connected to or integrally formed with the first housing 41. A first cover 418 is placed on the first mounting plate 43 and together with the first mounting plate 43 forms a first mounting cavity. A first transmission component 4232 is located in the first mounting cavity and is mounted on the first mounting plate 43.

[0057] Preferably, such as Figures 2 to 3 , Figure 5 and Figure 7 As shown, the second control valve 5 includes a second housing 51 and a second switching component 52 disposed within the second housing 51. The second switching component 52 is configured to allow the third interface 511 to selectively communicate with the third flow channel 513 and the fourth interface 512 to selectively communicate with the fourth flow channel 514.

[0058] By configuring the second control valve 5 to include a second housing 51 and a second switching component 52 disposed within the second housing 51, and enabling the second switching component 52 to selectively connect the third interface 511 to the third flow channel 513 and the fourth interface 512 to selectively connect to the fourth flow channel 514, the second control valve 5 achieves the function of controlling the inlet and outlet water of the softening tank 3. In the water production mode, purified water enters the softening tank 3 through the inlet flow channel and the third interface 511 for softening treatment. The softened water enters the outlet flow channel through the fourth interface 512 and flows back to the soft water outlet 23. In the forward or reverse washing mode, the direction of water flow can be changed by switching to achieve forward or reverse washing of the resin inside the softening tank 3.

[0059] Preferably, such as Figure 7 As shown, the second housing 51 is also provided with a wastewater interface 54, and the second switching component 52 is also configured to enable the third interface 511 or the fourth interface 512 to connect with the wastewater interface 54.

[0060] By setting a wastewater interface 54 on the second housing 51 and enabling the second switching component 52 to connect the third interface 511 or the fourth interface 512 to the wastewater interface 54, the rinsing water can be directly guided to the wastewater interface 54 for discharge through the third interface 511 or the fourth interface 512 in the forward washing mode, backwash mode, and regeneration mode. This achieves efficient discharge of cleaning wastewater from the softening tank 3. At the same time, the wastewater discharge function is integrated into the second control valve 5, eliminating the need for an additional independent sewage pipe, simplifying the water circuit layout of the equipment, avoiding cross-contamination between the cleaning wastewater and the product water circuit, and improving the quality of the effluent and the hygiene and safety of the system.

[0061] Preferably, such as Figures 16-17 , Figure 19 , Figure 21 , Figure 23 , Figure 30As shown, a second water cavity 5151 is also provided inside the second housing, and a second moving plate 521 and a second fixed plate 522 are disposed inside the second water cavity 5151.

[0062] More preferably, such as Figure 21 , Figure 25 and Figure 32 As shown, a fifth water chamber 5152 is also provided inside the second housing 51, and the wastewater interface 54 is connected to the fifth water chamber 5152.

[0063] Preferably, such as Figure 9 , Figure 12 and Figure 13 As shown, the second switching component 52 includes a second fixed plate 522, a second movable plate 521, and a second driving mechanism. The second fixed plate 522 is provided with a plurality of second fixed channels, and the second movable plate 521 is provided with a plurality of second movable channels. The second driving mechanism is drivenly connected to the second movable plate 521 to drive the second movable plate 521 to rotate relative to the second fixed plate 522, so that at least one of the second movable channels overlaps with at least one of the second fixed channels.

[0064] By configuring the second switching component 52 with a structure in which the second fixed plate 522 and the second moving plate 521 cooperate, and by driving the second moving plate 521 to rotate relative to the second fixed plate 522 through the second driving mechanism, water circuit switching is achieved. This rotating plate switching structure has the advantages of good sealing performance, precise switching position, wear resistance and durability, and long service life. It can effectively ensure the accuracy and reliability of the flow channel switching of the second control valve 5 in different working modes such as water production, forward washing, backwashing, and regeneration.

[0065] Specifically, such as Figure 13 As shown, the second moving channel includes a third through hole 5211, a fourth through hole 5212, a fifth through hole 5213, and a third water tank 5214. The third through hole 5211, the fourth through hole 5212, and the fifth through hole 5213 all penetrate the second moving piece 521 along the axial direction of the second moving piece 521. The third water tank 5214 is located on the side close to the second fixed piece 522 and does not penetrate the second moving piece 521.

[0066] like Figure 12 As shown, the second fixed channel includes a sixth water passage 5221, a seventh water passage 5222, an eighth water passage 5223, a ninth water passage 5224, and a tenth water passage 5225. The sixth water passage 5221, the seventh water passage 5222, the eighth water passage 5223, the ninth water passage 5224, and the tenth water passage 5225 all penetrate the second fixed plate 522 along the axial direction of the second fixed plate 522.

[0067] It should be noted that the second switching component 52 is not limited to including a second fixed plate 522, a second movable plate 521, and a second driving mechanism. For example, the second switching component 52 can also be configured as a piston-type switching structure, where the water path switching is achieved through the reciprocating linear motion of one or more pistons within the valve body; or, the second switching component 52 can be configured as a valve core rotation-type switching structure, where the water path switching is achieved through the rotational motion of a valve core with channels within the valve body. Such adjustments and changes to the specific configuration of the second switching component 52 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model. Preferably, the second switching component 52 is configured to include a second fixed plate 522, a second movable plate 521, and a second driving mechanism to achieve water path switching.

[0068] It should also be noted that those skilled in the art can configure the second drive mechanism to include only the second drive component 5231, or the second drive mechanism can be configured to include the second drive component 5231 and the second transmission component 5232. Such adjustments and changes to the specific configuration of the second drive mechanism do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0069] Preferably, such as Figure 9 As shown, the second drive mechanism includes a second drive component 5231 and a second transmission component 5232. The second drive component 5231 is driven to be connected to the second moving piece 521 through the second transmission component 5232.

[0070] By setting the second drive mechanism as a combination of the second drive component 5231 and the second transmission component 5232, the second drive component 5231 transmits power to the second moving plate 521 through the second transmission component 5232. The type of the second drive component 5231 (such as a motor, a geared motor, etc.) and the transmission method (such as gear transmission, worm gear transmission, etc.) can be flexibly selected according to actual needs, which improves the adaptability of the control valve to different application scenarios and the controllability of the drive precision.

[0071] It is understood that those skilled in the art can configure the second drive component 5231 as a stepper motor, or as a geared motor, or as any other possible motor type. Those skilled in the art can make flexible choices according to actual needs.

[0072] It should be noted that this utility model does not limit the specific configuration type of the second transmission component 5232. For example, the second transmission component 5232 can be configured as a gear transmission, or it can be configured as a worm gear transmission. Such adjustments and changes to the specific configuration type of the second transmission component 5232 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0073] Preferably, such as Figure 9 As shown, the second transmission component 5232 includes a second transmission shaft 52321, a third gear 52322 and a fourth gear 52323. The third gear 52322 is connected to the output end of the motor, and the fourth gear 52323 is connected to the second moving plate 521 through the second transmission shaft 52321. The third gear 52322 and the fourth gear 52323 mesh with each other.

[0074] Specifically, such as Figure 5 and Figure 7 As shown, the second control valve 5 also includes a second mounting plate 53, which is fixedly connected to or integrally formed with the second housing 51. The second cover 518 is placed on the second mounting plate 53 and together with the second mounting plate 53 forms a second mounting cavity. The second transmission component 5232 is located in the second mounting cavity and is mounted on the second mounting plate 53.

[0075] It should be noted that this utility model does not limit the specific location of the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 on the purification tank 2. For example, the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 can be arranged radially along the purification tank 2, or the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 can be arranged at intervals along a first direction, with the axes of the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 parallel to each other, and the first direction perpendicular to the central axis of the purification tank 2. Such adjustments and changes to the specific location of the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 on the purification tank 2 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0076] Preferably, such as Figures 1 to 4 As shown, the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 are spaced apart along a first direction, and the axes of the raw water inlet 21, the purified water outlet 22, and the soft water outlet 23 are parallel to each other. The first direction is perpendicular to the central axis of the purification tank 2.

[0077] By arranging the raw water inlet 21, purified water outlet 22, and soft water outlet 23 at intervals along the radial direction of the purification tank 2, and making their axes parallel to each other, all external pipelines can be led out in the same direction, resulting in neat pipeline routing. This avoids pipeline crossings or mutual interference, significantly improving the equipment's adaptability to installation in confined spaces (such as under-sink spaces). Installers do not need to operate in multiple different directions when connecting pipelines; they only need to complete the connection of all pipelines on the same side of the purification tank 2, effectively improving installation efficiency and maintenance convenience.

[0078] Preferably, such as Figure 1 and Figure 2 As shown, the integrated water purifier and softener also includes a mounting shell 1, which forms a mounting chamber. The purification tank 2, softening tank 3, first control valve 4, and second control valve 5 are all installed in the mounting chamber.

[0079] Specifically, such as Figure 1 and Figure 2 As shown, the mounting housing 1 includes an outer shell 11, an outer cover 12, and a waist belt 13. The waist belt 13 is disposed between the outer shell 11 and the outer cover 12. The mounting chamber includes a first accommodating cavity and a second accommodating cavity. The first accommodating cavity is formed between the waist belt 13 and the outer shell 11, and the second accommodating cavity is formed between the waist belt 13 and the outer cover 12. The purification tank 2 and the softening tank 3 are installed in the first accommodating cavity, and the first control valve 4 and the second control valve 5 are installed in the second accommodating cavity. The mounting housing 1 is provided with a clearance groove 14 adapted to the raw water inlet 21, the purified water outlet 22, and the softened water outlet 23. The raw water inlet 21, the purified water outlet 22, and the softened water outlet 23 extend to the outside of the mounting chamber through the clearance groove 14.

[0080] It should be noted that the salt tank can be placed outside the mounting shell 1, or it can be placed inside the mounting shell 1. Such adjustments and changes to the specific placement of the salt tank do not deviate from the principle and scope of this utility model, and should be included within the protection scope of this utility model.

[0081] Preferably, the salt tank is disposed inside the mounting housing 1; further, the salt tank is disposed inside the first receiving cavity.

[0082] The specific working mode of the integrated water purifier and softener of this utility model will be introduced below in conjunction with the following situations.

[0083] Scenario 1: Water production station When the integrated water purifier and softener is in the water purification position, the first drive mechanism is controlled to drive the first moving plate 421 to rotate relative to the first fixed plate 422, so that the first through hole 4211 on the first moving plate 421 overlaps with the third water passage hole 4223 on the first fixed plate 422, and the first water tank 4214 on the first moving plate 421 overlaps with the first water passage hole 4221 and the second water passage hole 4222 on the first fixed plate 422. The second drive mechanism is controlled to drive the second moving plate 521 to rotate relative to the second fixed plate 522, so that the third through hole 5211 and the fourth through hole 5212 on the second moving plate 521 overlap with the seventh water passage hole 5222 and the sixth water passage hole 5221 on the second fixed plate 522, respectively, and the tenth water passage hole 5225 and the ninth water passage hole 5224 on the second fixed plate 522 overlap with the third water tank 5214 on the second moving plate 521.

[0084] like Figure 14 and Figure 15 As shown, water enters the purification tank 2 from the raw water inlet 21 and flows into the raw water channel 241. After being filtered by the purification filter element 27 in the purification tank 2, the purified water flows into the purified water channel 242. The purified water flows along the first central pipe 28 to the top of the purification tank 2. Part of the purified water flows out through the purified water outlet 22 for users to use, and the other part of the purified water flows into the first control valve 4 through the first interface 411.

[0085] like Figure 16 As shown, the purified water flowing into the first control valve 4 enters the first water chamber 4151 and flows into the first flow channel 413 in sequence through the first through hole 4211 on the first moving plate 421 and the third water passage hole 4223 on the first fixed plate 422. Then it flows into the second water chamber 5151 through the third flow channel 513 and flows into the softening tank 3 in sequence through the fourth through hole 5212 on the second moving plate 521, the sixth water passage hole 5221 on the second fixed plate 522, the third through hole 5211 on the second moving plate 521, and the seventh water passage hole 5222 on the second fixed plate 522. After passing through the upper water distributor 351 in the softening tank 3, it flows downward through the resin in the softening tank 3 to soften the purified water after purification by the purification tank 2.

[0086] like Figure 17 and Figure 18 As shown, the softened water flows into the second control valve 5 through the second central pipe 34, and then sequentially flows into the fourth flow channel 514 through the ninth water passage 5224 on the second fixed plate 522, the third water tank 5214 on the second moving plate 521, and the tenth water passage 5225 on the second fixed plate 522. It then flows into the second flow channel 414, and sequentially flows into the second water passage 4222 on the first fixed plate 422, the first water tank 4214 on the first moving plate 421, and the first water passage 4221 on the first fixed plate 422. Finally, it flows out from the soft water outlet 23 on the purification tank 2 for users to use.

[0087] Scenario 2: Washing station When the integrated water purifier and softener is in the forward washing position, the first drive mechanism is controlled to drive the first moving plate 421 to rotate relative to the first fixed plate 422, so that the first through hole 4211 on the first moving plate 421 overlaps with the third water passage hole 4223 on the first fixed plate 422, and the first water tank 4214 on the first moving plate 421 overlaps with the first water passage hole 4221 and the second water passage hole 4222 on the first fixed plate 422. The second drive mechanism is controlled to drive the second moving plate 521 to rotate relative to the second fixed plate 522, so that the third through hole 5211 and the fifth through hole 5213 on the second moving plate 521 overlap with the sixth water passage hole 5221 and the tenth water passage hole 5225 on the second fixed plate 522, respectively, and the third water tank 5214 on the second moving plate 521 overlaps with the eighth water passage hole 5223 and the ninth water passage hole 5224 on the second fixed plate 522.

[0088] like Figure 19 As shown, water enters the purification tank 2 from the raw water inlet 21 and flows into the raw water channel 241. After being filtered by the purification filter element 27 in the purification tank 2, the purified water flows into the purified water channel 242. The purified water flows along the first central pipe 28 to the top of the purification tank 2. Part of the purified water flows out through the purified water outlet 22 for users to use, and the other part of the purified water flows into the first control valve 4 through the first interface 411.

[0089] like Figure 19 As shown, the clean water flowing into the first control valve 4 enters the first water chamber 4151, and flows into the first flow channel 413 through the first through hole 4211 on the first moving plate 421 and the third water passage hole 4223 on the first fixed plate 422. Then it flows into the second water chamber 5151 through the third flow channel 513, and flows into the softening tank 3 through the third through hole 5211 on the second moving plate 521 and the sixth water passage hole 5221 on the second fixed plate 522. After passing through the upper water distributor 351 in the softening tank 3, it flows downward through the resin in the softening tank 3 to rinse the resin.

[0090] like Figure 20 and Figure 21 As shown, the wastewater generated during rinsing flows into the second control valve 5 through the fourth interface 512 along the second central pipe 34, and then flows into the fifth water chamber 5152 through the ninth water passage 5224, the third water tank 5214, and the eighth water passage 5223 on the second fixed plate 522 in sequence, and finally flows out from the wastewater interface 54, thus realizing the forward rinsing of the softening tank 3.

[0091] Scenario 3: Backwashing station When the water purifier and softener is in the backwashing position, the first drive mechanism is controlled to drive the first moving plate 421 to rotate relative to the first fixed plate 422, so that the first through hole 4211 on the first moving plate 421 overlaps with the second water passage hole 4222 on the first fixed plate 422. The second drive mechanism is controlled to drive the second moving plate 521 to rotate relative to the second fixed plate 522, so that the fourth through hole 5212 and the fifth through hole 5213 on the second moving plate 521 overlap with the tenth water passage hole 5225 and the ninth water passage hole 5224 on the second fixed plate 522, respectively, and so that the third water tank 5214 on the second moving plate 521 overlaps with the seventh water passage hole 5222 and the eighth water passage hole 5223 on the second fixed plate 522.

[0092] like Figure 22 As shown, water enters the purification tank 2 from the raw water inlet 21 and flows into the raw water channel 241. After being filtered by the purification filter element 27 in the purification tank 2, the purified water flows into the purified water channel 242. The purified water flows along the first central pipe 28 to the top of the purification tank 2. Part of the purified water flows out through the purified water outlet 22 for users to use, and the other part of the purified water flows into the first control valve 4 through the first interface 411.

[0093] like Figure 23 As shown, the purified water entering the first control valve 4 flows into the second control valve 5 through the second flow channel 414. The purified water flowing into the second control valve 5 flows into the second water chamber 5151 through the fourth flow channel 514, the tenth water passage hole 5225 on the second fixed plate 522, and the fourth through hole 5212 on the second moving plate 521. Then, it flows into the softening tank 3 through the fifth through hole 5213 on the second moving plate 521 and the ninth water passage hole 5224 on the second fixed plate 522. It then flows along the second central pipe 34 to the bottom of the softening tank 3 to backwash the resin in the softening tank 3.

[0094] like Figure 24 and Figure 25 As shown, the backwashing wastewater flows into the second control valve 5 from the third port 511, and then flows into the fifth water chamber 5152 through the seventh water passage 5222 on the second fixed plate 522, the third water tank 5214 on the second moving plate 521, and the eighth water passage 5223 on the second fixed plate 522 in sequence, and finally flows out from the wastewater port 54, thus realizing the backwashing of the softening tank 3.

[0095] Scenario 4: Regeneration Station When the integrated water purifier and softener is in the regeneration station, the first drive mechanism is controlled to drive the first moving plate 421 to rotate relative to the first fixed plate 422, so that the first through hole 4211 on the first moving plate 421 overlaps with the fourth water passage hole 4224 on the first fixed plate 422, and the second water tank 4213 on the first moving plate 421 overlaps with the fifth water passage hole 4225 and the second water passage hole 4222 on the first fixed plate 422, respectively. The second drive mechanism is controlled to drive the second moving plate 521 to rotate relative to the second fixed plate 522, so that the fourth through hole 5212 and the fifth through hole 5213 on the second moving plate 521 overlap with the tenth water passage hole 5225 and the ninth water passage hole 5224 on the second fixed plate 522, respectively, and the third water tank 5214 on the second moving plate 521 overlaps with the seventh water passage hole 5222 and the eighth water passage hole 5223 on the second fixed plate 522.

[0096] like Figure 26 As shown, water enters the purification tank 2 from the raw water inlet 21 and flows into the raw water channel 241. After being filtered by the purification filter element 27 in the purification tank 2, the purified water flows into the purified water channel 242. The purified water flows along the first central pipe 28 to the top of the purification tank 2. Part of the purified water flows out through the purified water outlet 22 for users to use, and the other part of the purified water flows into the first control valve 4 through the first interface 411.

[0097] like Figure 26 and Figure 27 As shown, the clean water entering the first control valve 4 flows into the first water chamber 4151, and then flows into the third water chamber 4152 through the first through hole 4211 on the first moving plate 421 and the fourth water passage hole 4224 on the first fixed plate 422 in sequence, and then flows into the ejector through the jet inlet 441.

[0098] like Figures 28 to 30 As shown, the clean water flowing into the ejector creates a negative pressure inside the ejector, drawing the brine from the salt tank into the ejector. The brine mixes with the clean water in the ejector and flows into the fourth water chamber 4153 through the ejector outlet 442. Then, it flows into the second flow channel 414 through the fifth water passage 4225 on the first fixed plate 422, the second water tank 4213 on the first moving plate 421, and the second water passage 4222 on the first fixed plate 422. It then flows into the fourth flow channel 514 of the second control valve 5, and then into the second water chamber 5151 through the tenth water passage 5225 on the second fixed plate 522 and the fourth through hole 5212 on the second moving plate 521. Finally, it flows into the softening tank 3 through the fifth through hole 5213 on the second moving plate 521 and the ninth water passage 5224 on the second fixed plate 522, regenerating the resin in the softening tank 3.

[0099] like Figure 31 and Figure 32As shown, the wastewater generated after regeneration flows into the second control valve 5 through the fourth interface 512, and then flows into the fifth water chamber 5152 through the seventh water passage 5222 on the second fixed plate 522, the third water tank 5214 on the second moving plate 521, and the eighth water passage 5223 in sequence, and finally flows out from the wastewater interface 54.
