Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically providing a bypass valve for water treatment equipment and a water treatment system. Background Technology

[0002] As people's living standards improve, their demand for drinking water is also increasing. Water treatment equipment such as water softeners and water purifiers are gradually becoming essential drinking water facilities in people's daily lives. Water softeners mainly remove calcium and magnesium ions from water through ion exchange resins, reducing water hardness to meet users' needs for soft water.

[0003] In existing technologies, water treatment equipment has a relatively simple water circuit, and the quality of the output water cannot be adjusted. Taking a water softener as an example, after the water softener is installed, the entire pipeline in the whole house produces soft water. However, when users do not need to use soft water in certain scenarios, they cannot adjust the hardness of the output water, resulting in a poor user experience. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the user experience is poor because existing water treatment equipment cannot adjust the quality of the effluent after installation.

[0005] In a first aspect, the present invention provides a bypass valve for a water treatment device having an inlet and an outlet. The bypass valve includes: a housing having a first flow channel, a second flow channel, and a bypass flow channel; the first flow channel having a first inlet and a first outlet communicating with the inlet; the second flow channel having a second inlet and a second outlet communicating with the outlet; and a valve assembly configured to switch the bypass valve between at least two of the following states: in the first state, the first inlet is connected to the first outlet and the second inlet is connected to the second outlet, and the bypass flow channel is not connected to either the first or the second flow channel; in the second state, both ends of the bypass flow channel are connected to the first flow channel and the second flow channel, respectively, and the first inlet is disconnected from the first outlet and the second inlet is disconnected from the second outlet; in the third state, the first inlet is connected to the first outlet and the second inlet is connected to the second outlet, and both ends of the bypass flow channel are connected to the first and the second flow channel, respectively.

[0006] In the preferred embodiment of the bypass valve for water treatment equipment described above, the valve assembly includes a drive mechanism and a first valve core and a second valve core disposed within the housing. The first valve core is located at the junction of the first flow channel and the bypass flow channel, and the second valve core is located at the junction of the second flow channel and the bypass flow channel. The drive mechanism is capable of driving the first valve core and the second valve core to rotate relative to the housing, so that the bypass valve switches between at least two states among the first state, the second state, and the third state.

[0007] In the preferred embodiment of the bypass valve for water treatment equipment described above, the first valve core includes a first body and a first sealing member disposed on the first body, and the driving mechanism is drivenly connected to the first body to drive the first sealing member to rotate relative to the housing; and / or, the second valve core includes a second body and a second sealing member disposed on the second body, and the driving mechanism is drivenly connected to the second body to drive the second sealing member to rotate relative to the housing.

[0008] In the preferred embodiment of the bypass valve for the water treatment equipment described above, the bypass valve also has a closed state. In the closed state, the first inlet, the first outlet, and the bypass flow channel are all cut off. The valve assembly is also configured to enable the bypass valve to switch to the closed state.

[0009] In the preferred embodiment of the bypass valve for water treatment equipment described above, the drive mechanism includes a drive component and a transmission component. The drive component is driven to the first valve core and / or the second valve core through the transmission component, so as to drive the first valve core and the second valve core to rotate relative to the housing.

[0010] In the preferred embodiment of the bypass valve for water treatment equipment described above, the transmission component includes a first gear and a second gear meshing with the first gear. The first gear is fixedly connected to the first valve core, and the second gear is fixedly connected to the second valve core. The driving component is drivenly connected to the first gear or the second gear.

[0011] In the preferred embodiment of the bypass valve for water treatment equipment described above, the drive mechanism further includes a transmission connector. The drive component is driven to connect with the first gear or the second gear through the transmission connector. The transmission connector has a first connection structure and a second connection structure. The first gear or the second gear is provided with a third connection structure adapted to the first connection structure. The output end of the drive component is provided with a fourth connection structure adapted to the second connection structure.

[0012] In the preferred embodiment of the bypass valve for water treatment equipment described above, the bypass valve further includes a position detection component. The position detection component is used to acquire the current position information of the first valve core and / or the second valve core. The drive mechanism is communicatively connected to the position detection component so as to selectively control the rotation of the first valve core and / or the second valve core based on the current position information to switch the bypass valve to a target working state. And / or, the bypass valve further includes a connector. The housing is provided with a through hole adapted to the connector, and the first valve core and / or the second valve core is provided with a connector groove adapted to the connector. The connector can pass through the through hole and be inserted into the connector groove to install the first valve core and / or the second valve core into the housing.

[0013] In the preferred embodiment of the bypass valve for water treatment equipment described above, the housing is further provided with a first backup flow channel communicating with the first flow channel, and the bypass valve further includes a first sealing element adapted to the first backup flow channel, the first sealing element being used to open or close the first backup flow channel; and / or, the housing is further provided with a second backup flow channel communicating with the second flow channel, and the bypass valve further includes a second sealing element adapted to the second backup flow channel, the second sealing element being used to open or close the second backup flow channel.

[0014] In a second aspect, the present invention also provides a water treatment system, the water treatment system including water treatment equipment and the bypass valve described in the first aspect.

[0015] When the above-mentioned preferred technical solution is adopted, by setting the bypass valve to switch between at least two of the first, second and third states, the flow channel inside the bypass valve can be switched to switch to different states of the bypass valve, thereby enabling the connected water treatment equipment to have an adjustable water output mode, and thus enabling the water treatment equipment to output multiple water qualities to meet the user's water needs in different scenarios, greatly improving the user experience.

[0016] Furthermore, by configuring the valve assembly to include two independent rotary valve cores, precise zoned control of the flow channel opening and closing can be achieved, which not only ensures sealing reliability and reduces water resistance, but also protects the core internal components of the water softener, further enhancing the user experience.

[0017] Furthermore, by configuring the valve assembly to allow the bypass valve to switch to the closed state, it is also possible to cut off the first inlet and the first outlet, as well as the bypass flow channel, and the second inlet and the second outlet. In this way, when the water treatment equipment leaks, the bypass valve can block the first inlet and the second outlet, preventing water from continuing to enter the water treatment equipment and thus preventing the leakage from worsening.

[0018] Furthermore, by setting up transmission connectors, rapid disassembly and precise alignment between the drive component and the valve core can be achieved, eliminating the need for precise alignment when assembling the drive component and the valve body. The rapid adaptation of the first and third connection structures, as well as the second and fourth connection structures, significantly improves production and assembly efficiency. At the same time, the connection between the drive component and the valve core via the transmission connectors can absorb and compensate for any coaxiality errors that may exist between the drive component and the valve core gears, avoiding jamming or wear caused by installation deviations, and improving the smoothness and service life of the transmission system.

[0019] Furthermore, by setting up a position detection component, the position of the valve core can be sensed in real time. This allows for precise control of the drive mechanism's actions based on the sensed real-time position of the valve core. When the drive mechanism drives the first valve core and / or the second valve core to rotate to a preset position, the flow channel switching accuracy of the bypass valve is greatly improved, thereby enhancing the bypass valve's intelligence level and control precision.

[0020] Furthermore, by setting the valve core and housing to be installed via a plug-in connector, the valve core and housing can be quickly positioned and installed, improving the assembly efficiency of the bypass valve. At the same time, this plug-in structure also facilitates the disassembly and maintenance of the valve core, making the inspection, cleaning, or replacement of the valve core more convenient and quick.

[0021] Furthermore, by setting a backup flow channel on the shell, the backup flow channel can be selectively activated according to actual needs by adjusting the state of the sealing component. This allows the bypass valve to adapt to different water systems, expanding the application scenarios of the bypass valve. At the same time, it also provides greater flexibility for subsequent system upgrades or modifications.

[0022] Furthermore, the water treatment system further provided by the present invention, based on the aforementioned bypass valve for water treatment equipment, possesses the beneficial effects of the aforementioned bypass valve for water treatment equipment since it includes the aforementioned bypass valve for water treatment equipment. Compared with the water treatment system before the improvement, the water treatment system of the present invention can output water of different qualities to users, realize the adjustability of the output water quality, and provide a better user experience.

Detailed Implementation

[0025] 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.

[0026] It should be noted that in the description of this invention, 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 invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly, for example, referring 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 invention according to the specific circumstances.

[0028] In view of the problem mentioned in the background art that existing water treatment equipment leads to poor user experience due to the inability to adjust the effluent quality after installation, the present invention provides a bypass valve for water treatment equipment.

[0029] Specifically, such as Figures 1 to 3 As shown, the bypass valve 1 for water treatment equipment 2 of the present invention includes a housing 11 and a valve assembly. The water treatment equipment 2 has an inlet 21 and an outlet 22. The housing 11 has a first flow channel 111, a second flow channel 112 and a bypass flow channel 113. The first flow channel 111 has a first inlet 1111 and a first outlet 1112 communicating with the inlet 21 of the water treatment equipment 2. The second flow channel 112 has a second inlet 1121 and a second outlet 1122 communicating with the outlet 22 of the water treatment equipment 2.

[0030] The valve assembly is configured to enable the bypass valve 1 to switch between at least two of the first, second, and third states: In the first state, the first inlet 1111 is connected to the first outlet 1112 and the second inlet 1121 is connected to the second outlet 1122, while the bypass channel 113 is not connected to either the first channel 111 or the second channel 112. In the second state, both ends of the bypass channel 113 are connected to the first channel 111 and the second channel 112, respectively, and the first inlet 1111 is disconnected from the first outlet 1112 and the second inlet 1121 is disconnected from the second outlet 1122. In the third state, the first inlet 1111 is connected to the first outlet 1112 and the second inlet 1121 is connected to the second outlet 1122, while both ends of the bypass channel 113 are connected to the first channel 111 and the second channel 112, respectively.

[0031] By setting the bypass valve 1 to switch between at least two of the first, second, and third states, the flow channels inside the bypass valve 1 can be switched to different states of the bypass valve 1, thereby enabling the connected water treatment equipment 2 to have an adjustable water output mode. This allows the water treatment equipment 2 to output multiple water qualities, meeting the user's water needs in different scenarios and greatly improving the user experience.

[0032] It is understood that the present invention does not limit the specific formation of the first flow channel 111, the second flow channel 112, and the bypass flow channel 113 within the housing 11. As long as the first flow channel 111, the second flow channel 112, and the bypass flow channel 113 are formed within the housing 11, for example, the housing 11 can be a water channel plate, in which the first flow channel 111, the second flow channel 112, and the bypass flow channel 113 are formed. Alternatively, the housing 11 can also include multiple interconnected pipes, in which the first flow channel 111, the second flow channel 112, and the bypass flow channel 113 are formed. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0033] Preferably, such as Figures 4 to 7 , Figures 10 to 17As shown, the housing 11 is a water channel plate, and the water channel plate has a first flow channel 111, a second flow channel 112 and a bypass flow channel 113.

[0034] It should be noted that, in practical applications, those skilled in the art can configure the water treatment device 2 as a water softener, or as a water purifier, or even as a mineralized drinking water machine. Such adjustments and changes to the specific configuration of the water treatment device 2 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0035] The bypass valve 1 of the present invention will be described below using water treatment equipment 2 as an example of a water softener.

[0036] Specifically, such as Figure 1 , Figure 10 and Figure 11 As shown, in the first state, the bypass valve 1 is connected to the first inlet 1111 and the first outlet 1112, and the second inlet 1121 and the second outlet 1122. The bypass channel 113 is not connected to either the first channel 111 or the second channel 112, so that the water flowing into the first inlet 1111 flows through the first channel 111 into the inlet 21 of the water treatment equipment 2. The soft water treated by the water treatment equipment 2 flows through the outlet 22 to the second inlet 1121, and flows out through the second channel 112 from the second outlet 1122, providing the user with soft water softened by the water treatment equipment 2.

[0037] like Figure 2 , Figure 12 and Figure 13 As shown, in the second state, the bypass valve 1 has its two ends of the bypass channel 113 connected to the first channel 111 and the second channel 112 respectively. Furthermore, the first inlet 1111 is cut off from the first outlet 1112 and the second inlet 1121 is cut off from the second outlet 1122, so that the water flowing into the first inlet 1111 flows through the first channel 111, the bypass channel 113, and the second channel 112 and flows out directly from the second outlet 1122, providing the user with hard water that has not been softened by the water treatment equipment 2.

[0038] like Figure 3 , Figure 14 and Figure 15As shown, in the third state, the bypass valve 1 is connected to the first inlet 1111 and the first outlet 1112, and the second inlet 1121 and the second outlet 1122. The two ends of the bypass channel 113 are connected to the first channel 111 and the second channel 112, respectively, so that a portion of the water flowing into the first inlet 1111 flows into the inlet 21 of the water treatment equipment 2 through the first channel 111. The soft water treated by the water treatment equipment 2 flows to the second inlet 1121 through the outlet 22 and flows out from the second outlet 1122 through the second channel 112. The other portion flows out from the second outlet 1122 through the first channel 111, the bypass channel 113, and the second channel 112, so as to provide users with a mixture of soft water softened by the water treatment equipment 2 and hard water not softened by the water treatment equipment 2.

[0039] It is understandable that the valve assembly can be configured to allow the bypass valve 1 to switch only between the first and second states, or the valve assembly can be configured to allow the bypass valve 1 to switch only between the first and third states, or the valve assembly can be configured to allow the bypass valve 1 to switch only between the second and third states, or the valve assembly can be configured to allow the bypass valve 1 to switch between the first, second, and third states.

[0040] It should also be noted that the present invention does not impose any limitations on the specific configuration type of the valve assembly, as long as the valve assembly can enable the bypass valve 1 to switch between at least two of the first, second, and third states.

[0041] In one specific embodiment, such as Figures 5 to 9 As shown, the valve assembly includes a drive mechanism and a first valve core 122 and a second valve core 123 disposed within the housing 11. The first valve core 122 is located at the junction of the first flow channel 111 and the bypass flow channel 113, and the second valve core 123 is located at the junction of the second flow channel 112 and the bypass flow channel 113. The drive mechanism can drive the first valve core 122 and the second valve core 123 to rotate relative to the housing 11, so that the bypass valve 1 switches between at least two states in the first state, the second state, and the third state.

[0042] In another possible embodiment, the valve assembly may also be configured as an axially movable plunger valve core, which opens or closes the corresponding flow port by controlling the position of the plunger, so that the bypass valve 1 switches between at least two states in the first state, the second state, and the third state.

[0043] Specifically, the valve assembly includes one or more axially movable valve cores (such as ceramic cores, rubber heads + metal rods), which are driven to move up and down by an electromagnet, a motor screw or a manual push rod to open or close specific flow passages.

[0044] In another possible embodiment, the valve assembly may also consist of multiple independently controlled solenoid valves, which can be controlled to switch the bypass valve 1 between at least two states in a first state, a second state, and a third state.

[0045] Preferably, such as Figures 5 to 9 As shown, the valve assembly includes a drive mechanism and a first valve core 122 and a second valve core 123 disposed within the housing 11. The first valve core 122 is located at the junction of the first flow channel 111 and the bypass flow channel 113, and the second valve core 123 is located at the junction of the second flow channel 112 and the bypass flow channel 113. The drive mechanism can drive the first valve core 122 and the second valve core 123 to rotate relative to the housing 11, so that the bypass valve 1 switches between at least two states in the first state, the second state, and the third state.

[0046] By configuring the valve assembly to include two independent rotary valve cores, precise zoned control of the flow channel opening and closing can be achieved, which not only ensures sealing reliability and reduces water resistance, but also protects the core internal components of the water softener, further enhancing the user experience.

[0047] It should be noted that, in practical applications, those skilled in the art can configure the first valve core 122 to include a hollow first body 1221, by opening holes in the side wall of the first body 1221 to allow water flowing from the first inlet 1111 into the first flow channel 111 to flow to the first outlet 1112 and / or bypass flow channel 113. Alternatively, the first valve core 122 can be configured to include the first body 1221 and a first sealing member 1222 disposed on the first body 1221. When the drive mechanism drives the first body 1221 to rotate relative to the housing 11, the first sealing member 1222 can rotate with the first body 1221 to block the corresponding flow channel so that the water flowing from the first inlet 1111 into the first flow channel 111 flows to the first outlet 1112 and / or bypass flow channel 113, etc. Such adjustments and changes to the specific configuration of the first valve core 122 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0048] Preferably, such as Figure 8 As shown, the first valve core 122 includes a first body 1221 and a first sealing member 1222 disposed on the first body 1221. The driving mechanism is drivenly connected to the first body 1221 to drive the first sealing member 1222 to rotate relative to the housing 11.

[0049] It should be noted that, in practical applications, those skilled in the art can configure the second valve core 123 to include a hollow second body 1231, and by opening holes in the side wall of the second body 1231, allow water flowing into the second flow channel 112 from the second inlet 1121 and / or from the bypass flow channel 113 to flow out from the second outlet 1122. Alternatively, the second valve core 123 can be configured to include the second body 1231 and a second sealing member 1232 disposed on the second body 1231. During the rotation of the second body 1231 by the driving mechanism, the second sealing member 1232 can block or partially block the corresponding flow channel, so that water flowing into the second flow channel 112 from the second inlet 1121 and / or from the bypass flow channel 113 to flow out from the second outlet 1122, etc. Such adjustments and changes to the specific configuration of the second valve core 123 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0050] Preferably, such as Figure 8 As shown, the second valve core 123 includes a second body 1231 and a second sealing member 1232 disposed on the second body 1231. The drive mechanism is drivenly connected to the second body 1231 to drive the second sealing member 1232 to rotate relative to the housing 11.

[0051] It should be noted that the present invention may set both the first sealing member 1222 and the second sealing member 1232 as sealing gaskets, or both the first sealing member 1222 and the second sealing member 1232 as sealing blocks, etc. Such adjustments and changes to the specific configuration of the first sealing member 1222 and the second sealing member 1232 do not deviate from the principle and scope of the present invention, and should be included within the protection scope of the present invention.

[0052] In some specific embodiments, such as Figure 16 and Figure 17 As shown, the bypass valve 1 also has a closed state. In the closed state, the first inlet 1111, the first outlet 1112, and the bypass flow channel 113 are all cut off. The valve assembly is also configured to enable the bypass valve 1 to switch to the closed state.

[0053] By configuring the valve assembly to switch the bypass valve 1 to the closed state, the first inlet 1111, the first outlet 1112, and the bypass channel 113 can all be cut off, as can the second inlet 1121 and the second outlet 1122. In this way, when the water treatment equipment 2 leaks, the bypass valve 1 can block the first inlet 1111 and the second outlet 1122, preventing water from continuing to enter the water treatment equipment 2 and thus preventing the leakage from worsening.

[0054] Specifically, the drive mechanism drives the first valve core 122 to rotate and rotates the first sealing member 1222 to face the first inlet 1111. Then the water source flowing to the first inlet 1111 cannot flow to the water treatment equipment 2 through the first outlet 1112. That is, the first valve core 122 blocks the first inlet 1111 to prevent water from continuing to enter the water treatment equipment 2.

[0055] It should be noted that, in practical applications, those skilled in the art do not impose any limitations on the specific configuration type of the drive mechanism. For example, the drive mechanism can be configured to include a drive component 1211 and a transmission component, with the drive component 1211 being driven to the first valve core 122 and / or the second valve core 123 via the transmission component, so as to drive the first valve core 122 and the second valve core 123 to rotate relative to the housing 11. Alternatively, the drive mechanism can be configured to include only the drive component 1211, which is directly driven to the first valve core 122 and the second valve core 123 via the drive component 1211, so as to drive the first valve core 122 and the second valve core 123 to rotate relative to the housing 11, and so on. Such adjustments and changes to the specific configuration type of the drive mechanism do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0056] Preferably, such as Figures 5 to 9 As shown, the drive mechanism includes a drive component 1211 and a transmission component. The drive component 1211 is driven to the first valve core 122 and / or the second valve core 123 via the transmission component to drive the first valve core 122 and the second valve core 123 to rotate relative to the housing 11.

[0057] By configuring the drive mechanism in this way, compared to configuring the drive mechanism only as a drive component 1211, configuring the drive mechanism in the form of a drive component 1211 and a transmission component can improve the driving reliability of the drive component 1211. At the same time, it is convenient to adjust the driving force and speed through the transmission component. In addition, the configuration of the transmission component allows a single drive component 1211 (such as a motor) to drive the first valve core 122 and the second valve core 123 to rotate simultaneously. This not only saves on component and control costs, but also ensures the mechanical synchronization of the rotation of the two valve cores and eliminates the switching delay and cross-contamination risk that may be caused by electronic asynchronous control.

[0058] It should be noted that, in practical applications, the present invention does not impose any limitations on the specific type of transmission component. For example, the transmission component can be configured as a gear transmission module, such as a first gear 1212 and a second gear 1213 meshing with each other, with a driving component 1211 connected to one of the first gear 1212 and the second gear 1213. The first gear 1212 is fixedly connected to the first valve core 122, and the second gear 1213 is fixedly connected to the second valve core 123. Alternatively, the transmission component can be configured as a chain transmission module, such as a first gear 1212, a second gear 1213, and a chain, with the chain located at the first gear 1212. 2. On the outside of the second gear 1213, the first gear 1212 is fixedly connected to the first valve core 122, and the second gear 1213 is fixedly connected to the second valve core 123. The driving member 1211 is driven to one of the first gear 1212 and the second gear 1213. The driving member 1211 drives one of the first gear 1212 and the second gear 1213 to rotate. The chain drives the other of the first gear 1212 and the second gear 1213 to rotate. Alternatively, the transmission member can be set in any other possible form, etc. Such adjustments and changes to the specific setting type of the transmission member do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0059] It should be noted that those skilled in the art can configure the driving component 1211 to be driven connected to the first gear 1212 to drive the first gear 1212 to rotate, and the first gear 1212 drives the second gear 1213 to rotate. Alternatively, the driving component 1211 can be configured to be driven connected to the second gear 1213 to drive the second gear 1213 to rotate, and the second gear 1213 drives the first gear 1212 to rotate, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0060] Preferably, such as Figures 5 to 8 As shown, the transmission component includes a first gear 1212 and a second gear 1213 meshing with the first gear 1212. The first gear 1212 is fixedly connected to the first valve core 122, the second gear 1213 is fixedly connected to the second valve core 123, and the driving component 1211 is drivenly connected to the first gear 1212.

[0061] With this configuration, the drive component 1211 can drive the first gear 1212 to rotate relative to the housing 11. Since the first gear 1212 meshes with the second gear 1213, the first gear 1212 drives the second gear 1213 to rotate relative to the housing 11. In this way, the first gear 1212 and the second gear 1213 can rotate synchronously, and the number of drive components 1211 used can be reduced, thus reducing the production cost of the bypass valve 1.

[0062] It should be noted that, in practical applications, those skilled in the art can configure the drive component 1211 to be directly connected to the first gear 1212, or the drive component 1211 can be configured to be connected to the first gear 1212 via a drive connector, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0063] Preferably, such as Figures 7 to 9 As shown, the drive mechanism also includes a transmission connector 124. The drive member 1211 is driven to be connected to the first gear 1212 through the transmission connector 124. The transmission connector 124 has a first connection structure 1241 and a second connection structure 1242. The first gear 1212 is provided with a third connection structure 12121 adapted to the first connection structure 1241. The output end of the drive member 1211 is provided with a fourth connection structure 12111 adapted to the second connection structure 1242.

[0064] By setting the transmission connector 124, the drive component 1211 and the valve core can be quickly disassembled and precisely aligned, so that the assembly of the drive component 1211 and the valve body does not require precise alignment. Through the rapid adaptation of the first connection structure 1241 and the third connection structure 12121, and the second connection structure 1242 and the fourth connection structure 12111, the production assembly efficiency is significantly improved. At the same time, the drive component 1211 is connected to the valve core through the transmission connector 124, which can absorb and compensate for the coaxiality error that may exist between the drive component 1211 and the valve core gear, avoid jamming or wear caused by installation deviation, and improve the smoothness and service life of the transmission system.

[0065] It should be noted that the present invention does not limit the specific structural types of the first connecting structure 1241 and the third connecting structure 12121. For example, one of the first connecting structure 1241 and the third connecting structure 12121 can be configured as a claw, and the other of the first connecting structure 1241 and the third connecting structure 12121 can be configured as a slot adapted to the claw. Alternatively, one of the first connecting structure 1241 and the third connecting structure 12121 can be configured as a protrusion, and the other of the first connecting structure 1241 and the third connecting structure 12121 can be configured as a groove adapted to the protrusion, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0066] It should also be noted that the present invention does not limit the specific structural types of the second connecting structure 1242 and the fourth connecting structure 12111. For example, one of the second connecting structure 1242 and the fourth connecting structure 12111 can be set as a protruding post, and the other of the second connecting structure 1242 and the fourth connecting structure 12111 can be set as a groove. Alternatively, one of the second connecting structure 1242 and the fourth connecting structure 12111 can be set as a claw, and the other of the second connecting structure 1242 and the fourth connecting structure 12111 can be set as a slot, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0067] Preferably, such as Figures 7 to 9 As shown, the first connecting structure 1241 is a claw, the second connecting structure 1242 is a protrusion, the third connecting structure 12121 is a slot adapted to the claw, and the fourth connecting structure 12111 is a groove adapted to the protrusion.

[0068] With this configuration, the engagement of the claw and the slot can effectively transmit torque and prevent slippage. The engagement of the protrusion and the groove simplifies the connection process between the output end of the drive component 1211 and the transmission connector 124.

[0069] Specifically, such as Figure 5 As shown, the drive component 1211 is mounted on the housing 11 via the motor bracket 125.

[0070] In one possible embodiment, the bypass valve 1 further includes a position detection component, which is used to obtain the current position information of the first valve core 122 and / or the second valve core 123. The drive mechanism is communicatively connected to the position detection component so as to selectively control the rotation of the first valve core 122 and / or the second valve core 123 based on the current position information, so as to switch the bypass valve 1 to the target working state.

[0071] By setting a position detection component, the position of the valve core can be sensed in real time. Based on the sensed real-time position of the valve core, the action of the drive mechanism can be precisely controlled. When the drive mechanism drives the first valve core 122 and / or the second valve core 123 to rotate to the preset position, the flow channel switching accuracy of the bypass valve 1 is greatly improved, thereby improving the intelligence level and control accuracy of the bypass valve 1.

[0072] It should be noted that those skilled in the art are not limited in the specific configuration type of the position detection component, as long as it can obtain the current position information of the first valve core 122 and the second valve core 123. For example, the position detection component can be configured as a camera, which captures images of the first valve core 122 and the second valve core 123 and compares them with a preset image. The current position information of the first valve core 122 and the second valve core 123 can be obtained based on the comparison result. Alternatively, the position detection component can be configured as a position sensor and a positioning component 132, which uses the position sensor to sense the positioning component 132 to determine the current position information of the first valve core 122 and the second valve core 123, and so on. Such adjustments and changes to the specific configuration type of the position detection component do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0073] Preferably, such as Figure 6 , Figure 12 , Figure 14 , Figure 16 As shown, the position detection assembly includes a positioning member 132 and a position sensor (not shown in the figure). The positioning member 132 is disposed on the housing 11, and the position sensor is disposed on at least one of the first valve core 122, the second valve core 123, and the transmission member, so as to follow the rotation of the first valve core 122 and / or the second valve core 123.

[0074] It should be noted that the position sensor can be set on the first valve core 122 and / or the second valve core 123, or the position sensor can be set on the first gear 1212 and the second gear 1213, or the position sensor can be set on both the first valve core 122 and / or the second valve core 123 and the first gear 1212 and the second gear 1213.

[0075] Preferably, the first gear 1212 and the second gear 1213 are provided with positioning grooves 12122, and the position sensor is located in the positioning grooves 12122. When the drive mechanism drives the first valve core 122 and / or the second valve core 123 to rotate, the positioning member 132 can rotate along the positioning grooves 12122 and relative to the position sensor.

[0076] By setting the detection components as positioning member 132 and position sensor, the position sensor can follow the rotation of the first valve core 122 or the second valve core 123, eliminating the influence of transmission backlash or accumulated error on detection accuracy, thereby more accurately determining the real-time position of the valve core. When the position sensor senses the positioning member 132, it can provide feedback on the current position information of the first valve core 122 and the second valve core 123 more quickly and accurately, which helps to further improve the flow channel switching accuracy of the bypass valve 1.

[0077] It should be noted that the present invention does not impose any limitation on the specific placement position of the position sensor in the positioning groove 12122, as long as it can detect the current position information of the first valve core 122 and / or the second valve core 123.

[0078] In one specific embodiment, such as Figure 6 , Figure 12 , Figure 14 , Figure 16 As shown, the position sensor is located in the middle of the positioning slot 12122 (i.e., position B).

[0079] When the first valve core 122 and / or the second valve core 123 rotates to the position where the position sensor coincides with the positioning member 132 (i.e., the positioning member 132 coincides with the middle of the positioning groove 12122), the first valve core 122 and / or the second valve core 123 are detected to be in the first position. When the first valve core 122 and / or the second valve core 123 rotates to the point where one end of the positioning groove 12122 contacts the positioning member 132, the torque of the drive mechanism increases. The current position information of the first valve core 122 and / or the second valve core 123 is determined according to the rotation direction and number of rotation steps of the drive mechanism.

[0080] In another specific embodiment, position sensors are respectively disposed in the middle and at the ends (i.e., end A and end C) of the positioning groove 12122.

[0081] like Figure 10 As shown, when the first valve core 122 and / or the second valve core 123 rotate to the position where the position sensor in the middle coincides with the positioning member 132 (i.e., the positioning member 132 coincides with the middle of the positioning groove 12122), it is recorded as the first position; like Figure 12 As shown, when the first valve core 122 and / or the second valve core 123 rotate to the position where the position sensor at the first end (end A) coincides with the positioning member 132, it is recorded as the second position; like Figure 16 As shown, when the first valve core 122 and / or the second valve core 123 rotate to the position where the position sensor at the second end coincides with the positioning member 132, it is recorded as the third position.

[0082] It should be noted that although the present invention describes the specific setting position of the position sensor using the above two embodiments, this is not restrictive. For example, the position sensor may be set only in the middle of the positioning groove 12122 and at the first end of the positioning groove 12122, or it may be set only in the middle of the positioning groove 12122 and at the second end of the positioning groove 12122, etc. Such adjustments and changes to the specific setting position of the position sensor do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0083] Preferably, such as Figure 5 and Figure 8 , Figure 9 As shown, the bypass valve 1 also includes a connector 14. The housing 11 is provided with a through hole 114 adapted to the connector 14. The first valve core 122 and / or the second valve core 123 are provided with a connector groove 1223 adapted to the connector 14. The connector 14 can pass through the through hole 114 and be inserted into the connector groove 1223 to install the first valve core 122 and / or the second valve core 123 into the housing 11.

[0084] By configuring the valve core and housing 11 to be installed via a plug-in connector 14, the valve core and housing 11 can be quickly positioned and installed, improving the assembly efficiency of the bypass valve 1. At the same time, this plug-in structure also facilitates the disassembly and maintenance of the valve core, making the inspection, cleaning or replacement of the valve core more convenient and quick.

[0085] It should be noted that the present invention does not impose any limitations on the specific shape of the connector 14 and the connector groove 1223. For example, the connector 14 can be set as U-shaped, and the connector groove 1223 can be adapted to the two plug-in parts of the U-shaped connector 14. Alternatively, the connector 14 can be set as a straight strip, and the connector groove 1223 can be adapted to the two straight strip connectors 14, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0086] Preferably, the connector 14 is U-shaped, and the connector groove 1223 is adapted to the two connector portions of the U-shaped connector 14.

[0087] More preferably, the insertion groove 1223 is an annular groove.

[0088] It should be noted that the installation is not limited to mounting the valve core onto the housing 11 via the connector 14. For example, a rotating groove can be provided on the housing 11, and a sliding part can be provided on the first valve core 122 and / or the second valve core 123. The first valve core 122 and / or the second valve core 123 can be mounted onto the housing 11 by rotating the sliding part within the rotating groove. Such adjustments and changes to the specific mounting method of the valve core and the housing 11 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention. Of course, it is preferable that the valve core is mounted onto the housing 11 via the connector 14.

[0089] Preferably, such as Figures 1 to 5 , Figure 11 , Figure 13 , Figure 15 and Figure 17 As shown, the housing 11 is also provided with a first backup flow channel 151 that communicates with the first flow channel 111. The bypass valve 1 also includes a first sealing member 152 that is adapted to the first backup flow channel 151. The first sealing member 152 is used to open or close the first backup flow channel 151.

[0090] like Figures 1 to 5 , Figure 11 , Figure 13 , Figure 15 and Figure 17 As shown, the housing 11 is also provided with a second backup flow channel 161 that communicates with the second flow channel 112. The bypass valve 1 also includes a second sealing member 162 that is adapted to the second backup flow channel 161. The second sealing member 162 is used to open or close the second backup flow channel 161.

[0091] By setting a backup flow channel on the housing 11, the backup flow channel can be selectively activated according to actual needs by adjusting the state of the sealing component. This allows the bypass valve 1 to adapt to different water circuit systems, improving the application scenarios of the bypass valve 1. At the same time, it also provides greater flexibility for subsequent system upgrades or modifications.

[0092] It should be noted that the invention is not limited to providing a first backup flow channel 151 and a second backup flow channel 161 on the housing 11, and providing a first sealing member 152 adapted to the first backup flow channel 151 and a second sealing member 162 adapted to the second backup flow channel 161. For example, it is also possible to provide only the first backup flow channel 151 on the housing 11 and provide a first sealing member 152 adapted to the first backup flow channel 151, or it is also possible to provide only the second backup flow channel 161 on the housing 11 and provide a second sealing member 162 adapted to the second backup flow channel 161. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0093] Preferably, a first backup flow channel 151 and a second backup flow channel 161 are provided on the housing 11, and a first sealing member 152 adapted to the first backup flow channel 151 and a second sealing member 162 adapted to the second backup flow channel 161 are provided.

[0094] Preferably, such as Figure 4 As shown, the bypass valve of the present invention also includes an outer cover 17, which is disposed outside the drive mechanism and connected to the housing 11.

[0095] By setting up an outer cover, the outer cover 17 forms a physical barrier to the internal drive mechanism, effectively preventing dust, moisture and insects from entering, avoiding gear jamming or short circuits, significantly improving the product's environmental adaptability and service life. At the same time, it can effectively absorb and block the mechanical noise generated during motor operation and gear transmission, making the bypass valve operate more smoothly and quietly when switching states or adjusting mixing water, creating a more comfortable home environment for users.

[0096] It should be noted that the present invention does not limit the connection method between the outer cover 17 and the housing 11. For example, the outer cover 17 and the housing 11 can be connected by snap-fit, or the outer cover 17 can be fixedly connected to the housing 11 by fasteners, or the outer cover 17 can be connected to the housing 11 by threads, etc. Such adjustments and changes to the specific connection method between the outer cover 17 and the housing 11 do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0097] For example, the outer cover 17 is snap-fitted to the housing 11.

[0098] In addition, such as Figures 1 to 3 As shown, the present invention also provides a water treatment system, which includes a water treatment device 2 and a bypass valve 1. The bypass valve 1 has a first inlet 1111, a first outlet 1112, a second inlet 1121, and a second outlet 1122. The water treatment device 2 has an inlet 21 and an outlet 22. The first inlet 1111 is connected to a water source. The first outlet 1112 is connected to the inlet 21 of the water treatment device 2. The outlet 22 of the water treatment device 2 is connected to the second inlet 1121. The second outlet 1122 is connected to a water outlet component (a water tap or faucet).

[0099] like Figure 1As shown, when a user needs soft water, the bypass valve 1 is switched to the first state, the water source flows to the first inlet 1111, and flows out from the first outlet 1112 through the first flow channel 111, and then flows to the inlet 21, so that the water source enters the water treatment equipment 2 through the inlet 21. The water softened by the water treatment equipment 2 flows from the outlet 22 to the second inlet 1121, and then flows out from the second outlet 1122 through the second flow channel 112, so as to provide the user with soft water softened by the water treatment equipment 2.

[0100] like Figure 2 As shown, when a user needs hard water, the bypass valve 1 is switched to the second state, and the water source flows to the first inlet 1111, and flows out from the second outlet 1122 in sequence through the first flow channel 111, the bypass flow channel 113, and the second flow channel 112, so as to provide the user with hard water that has not been softened by the water treatment equipment 2.

[0101] like Figure 3 As shown, when the user requires water quality between soft and hard water, the bypass valve 1 is switched to the third state. A portion of the water source flowing to the first inlet 1111 flows into the water treatment device 2 through the first flow channel 111. The softened water after being treated by the water treatment device 2 flows out through the outlet 22 and then through the second flow channel 112 from the second outlet 1122. Another portion of the water source flowing to the first inlet 1111 flows through the first flow channel 111, the bypass flow channel 113, the second flow channel 112, and then out through the second outlet 1122. This allows the softened water after being treated by the water treatment device 2 to mix with the untreated hard water, so as to provide the user with water quality between soft and hard water.

[0102] It should be noted that although the present invention uses a water treatment device 2 as an example of a water softener to describe the bypass valve 1, this is not limiting. The bypass valve 1 of the present invention is also applicable to other types of water treatment devices 2 (such as water treatment devices 2 being water purifiers or mineralized drinking water machines), which will not be elaborated here.

[0103] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
