[0047] In the relevant technical field, the existing water circuit switching control mechanism of the water circuit board is relatively complex in design, which is not conducive to assembly and production, greatly increases the difficulty of product production, and reduces production efficiency.

[0048] This invention proposes a water circuit control system and a water softening device.

[0049] In embodiments of the present invention, such as Figures 1 to 5 As shown, the water circuit control assembly 200 includes a transition assembly 100 and a control assembly 200. The transition assembly 100 includes an inner valve body 120 and an outer valve body 110. The outer valve body 110 has a receiving cavity 111 and a first valve port 112, a second valve port 113, and a receiving opening 114, all of which are connected to the receiving cavity 111. A portion of the inner valve body 120 passes through the receiving opening 114 and is fixed within the receiving cavity 111. The inner end of the inner valve body 120 is located at the first valve port 112 and... Between the second valve port 113, the inner valve body 120 is provided with an inner valve cavity 121, an inner valve port 123a and a valve opening / closing port 123b. The valve opening / closing port 123b is located at the inner end. The inner valve port 123a connects the first valve port 112 and the inner valve cavity 121. The control component 200 is movably disposed in the inner valve cavity 121, and one end of a portion of the control component 200 abuts against the valve opening / closing port 123b. The control component 200 is used to control the opening and closing of the valve opening / closing port 123b.

[0050] The water softening device in this application includes a water circuit control system 10, water circuit components 20, a brine tank and a resin tank 30, etc., wherein the water circuit control system 10 includes a transfer component 100, a control component 200 and a drive component 600, etc.

[0051] The drive component 600 can be a soft water valve or a separate drive unit. This embodiment uses a soft water valve as the drive component 600 for explanation. Other embodiments can be implemented with reference to this embodiment. Using a soft water valve as the drive component 600 can reduce the volume occupied by a separate drive unit. At the same time, it can improve the synchronization between the control component 200 and the soft water valve.

[0052] The adapter 100 is connected between the water softener valve and the water circuit component 20. The resin tank 30 is used to contain resin for softening the raw water to be softened. The resin tank 30 is provided with a central pipe and a water distribution mechanism. The water distribution mechanism is used to evenly distribute the brine or raw water to contact the resin. The central pipe is used to lead the softened water out of the resin tank 30 or introduce the brine into the resin tank 30.

[0053] The water softener valve is used to control the flow of water into and out of the water softener and to switch between different flow paths to achieve different working modes of the water softener. These working modes include service mode, brine suction mode, slow wash mode, bypass mode, backwash mode, water replenishment mode, and mixing mode.

[0054] The brine tank is used to provide brine for resin backwashing. After being connected to the brine suction path of the adapter assembly 100 via a pipe, the brine tank is connected to the water circuit component 20 or the resin tank 30. The water circuit component 20 is used to connect to multiple resin tanks 30, enabling the parallel connection of multiple resin tanks 30.

[0055] The adapter assembly 100 is provided with a sewage discharge channel. One end of the sewage discharge channel is connected to the resin end of the resin tank 30 to lead the backwashed wastewater out of the resin tank 30. The other end is connected to the receiving cavity 111 of the outer valve body 110 through the second valve port 113. The first valve port 112 is a sewage discharge port, which is used to discharge the pollutants to a designated location through the connection between the receiving cavity 111 and the first valve port 112.

[0056] The adapter assembly 100 includes an outer valve body 110 and an inner valve body 120, which are detachably connected. The outer valve body 110 is used to provide the connection path of the receiving cavity 111, the first valve port 112, and the second valve port 113. A portion of the inner valve body 120 is disposed within the receiving cavity 111 and located between the first valve port 112 and the second valve port 113. The inner valve body 120 has an inner valve cavity 121 extending along the axial direction. An inner valve port 123a communicating with the inner valve cavity 121 is provided on the outer peripheral wall of the inner valve cavity 121. A valve opening / closing port 123b is provided on the inner end of the inner valve body 120. This opening / closing port is used to connect the second valve port 113 and the inner valve cavity 121. The control component 200 is movably disposed within the inner valve cavity 121, with one end abutting against the valve opening / closing port 123b. Thus, by cooperating with the control component 200, the opening and closing between the first valve port 112 and the second valve port 113 can be controlled.

[0057] This application simplifies the assembly process of the water circuit control system 10 by configuring the adapter component 100 as an inner valve body 120 and an outer valve body 110. The outer valve body 110 has a receiving cavity 111 inside, which is used to connect the first valve port 112 and the second valve port 113. The inner valve body 120 is sealed at the receiving opening 114 of the outer valve body 110. The inner valve body 120 is provided with an inner valve cavity 121, an inner valve port 123a and a valve opening / closing port 123b, which are used to cooperate with the control component 200 to control the opening and closing between the first valve port 112 and the second valve port 113. By configuring the adapter component 100 as an inner valve body 120 and an outer valve body 110, the assembly steps of the adapter component 10 can be simplified. At the same time, the molding process of the adapter component 100 can be simplified, the production difficulty can be reduced, and the production efficiency can be improved.

[0058] Reference Figure 3 and Figure 4 According to one embodiment of the present invention, an annular connecting groove 123c is provided on the outer wall of the inner valve body 120 at the position corresponding to the inner valve port 123a, and the inner valve port 123a is connected to the first valve port 112 through the annular connecting groove 123c. It is understood that providing an annular connecting groove 123c on the outer wall of the inner valve body 120 at the position corresponding to the inner valve port 123a, and connecting the inner valve port 123a to the first valve port 112 through the annular connecting groove 123c, can reduce the precision requirements during the assembly of the inner valve body 120 and the outer valve body 110, because the annular connecting groove 123c makes the connection between the inner valve port 123a and the first valve port 112 more flexible and less susceptible to assembly errors. Since the inner valve port 123a is located on the peripheral wall of the inner valve cavity 121 and corresponds to the axial position of the first valve port 112, the water flow direction is from the second valve port 113 into the receiving cavity 111, through the valve opening / closing port 123b into the inner valve cavity 121, then through the inner valve port 123a into the annular connecting groove 123c, and finally flows to the first valve port 112. Through the action of the control component 200, the water circuit is switched on and off. Simultaneously, the annular connecting groove 123c facilitates installation and alignment. During assembly, as long as the position of the annular connecting groove 123c corresponds to the position of the first valve port 112, the inner valve port 123a and the first valve port 112 can be connected. This simplifies the assembly steps and improves production efficiency.

[0059] Reference Figure 4According to one embodiment of the present invention, the inner valve body 120 includes a first valve body 122 and a second valve body 123 fixedly connected. The second valve body 123 is disposed within a receiving cavity 111, and the first valve body 122 is disposed at a receiving opening 114. The first valve body 122 is fitted into the end of the second valve body 123 facing the receiving opening 114. It is understood that since the first valve body 122 and the second valve body 123 are separately disposed, installation and disassembly become simpler. During the production process, the second valve body 123 can be installed in the receiving cavity 111 first, and then the first valve body 122 can be fixed to the receiving opening 114 by fitting. Similarly, when repairing or replacing the inner valve body 120, the first valve body 122 or the second valve body 123 can be easily disassembled and replaced. Furthermore, by dividing the inner valve body 120 into a first valve body 122 and a second valve body 123, different designs and selections can be made for the size, shape, and material of the first valve body 122 and the second valve body 123 according to actual needs. This allows the system to better adapt to different application scenarios and needs, improving the system's versatility and adaptability.

[0060] Reference Figure 4 and Figure 5 According to one embodiment of the present invention, the outer valve body 110 has a step 115 on its inner wall at one end of the receiving opening 114, and the outer peripheral wall of the inner valve body 120 has a radially protruding protrusion 122a, which abuts against the step 115. It is understood that the step 115 and the protrusion 122a simplify and refine the assembly of the inner valve body 120 and the outer valve body 110. During assembly, simply align the protrusion 122a of the inner valve body 120 with the step 115 of the outer valve body 110, and then apply appropriate force to ensure a tight abutment between the protrusion 122a and the step 115, thus achieving a fixed connection between the inner valve body 120 and the outer valve body 110. This assembly method simplifies the production process and improves production efficiency. Simultaneously, the tight abutment between the protrusion 122a and the step 115 effectively prevents loosening or sliding of the inner valve body 120. This reduces potential gaps or sliding, thereby improving the reliability and stability of the water circuit control system 10.

[0061] Reference Figures 3 to 5According to one embodiment of the present invention, the outer valve body 110 is provided with a retaining hole 116 on the outer peripheral side of one end of the receiving opening 114. The water circuit control system 10 also includes a connector 400, which is inserted into the retaining hole 116 and abuts against the protrusion 122a. It can be understood that the abutment between the step 115 and the protrusion 122a only limits one end of the inner valve body 120 and the outer valve body 110 along the axial direction, while the other end is limited by a retaining hole provided on the outer valve body 110, and the connector 400 is inserted into the retaining hole 116 to abut against the other side of the protrusion 122a opposite to the step 115, thereby limiting the other end of the inner valve body 120 and the outer valve body 110 along the axial direction. In this way, the disassembly and assembly and alignment of the inner valve body 120 and the outer valve body 110 are relatively simple and convenient, improving the disassembly and assembly efficiency.

[0062] Reference Figure 4 and Figure 5 According to one embodiment of the present invention, the control component 200 includes an abutment member 210, which is movably disposed within the inner valve cavity 121 and has an axially movable state for opening and closing the valve opening / closing port 123b, and a blocking state. It is understood that by adjusting the position of the abutment member 210, the opening and closing state of the valve opening / closing port 123b can be controlled, thereby achieving the opening or blocking of the water path. This simplifies the on / off setting of the valve opening / closing port 123b and improves the reliability and stability of the water path control. When the abutment member 210 moves away from the valve opening / closing port 123b, it changes the opening degree of the valve opening / closing port 123b, thereby achieving the opening of the water path. At this time, water can flow from the second valve port 113 into the inner valve cavity 121, and then flow out through the inner valve port 123a towards the first valve port 112, achieving the opening of the water flow. Conversely, when the abutment 210 moves toward the valve opening / closing port 123b, it blocks the valve opening / closing port 123b, thereby sealing the water passage. At this time, water cannot flow through the valve opening / closing port 123b, thus closing the water passage.

[0063] Reference Figures 3 to 5 According to one embodiment of the present invention, the control assembly 200 further includes an elastic element 500, which abuts against the inner valve body 120 and the abutment member 210. The elastic element 500 provides a restoring force to the abutment member 210 against the valve opening / closing port 123b. It is understood that the design of the elastic element 500 allows the abutment member 210 to automatically return to its initial state, providing stability and reliability for the control of the water circuit. When the control signal changes, the abutment member 210 moves accordingly to change the opening degree of the valve opening / closing port 123b. The function of the elastic element 500 is to provide a restoring force so that the abutment member 210 can automatically return to its initial position after the control signal is released. Thus, by introducing the elastic element 500 into the control assembly 200 to provide a restoring force to the abutment member 210 against the valve opening / closing port 123b, stability and reliability of the water circuit control are achieved.

[0064] Reference Figure 4 and Figure 5 According to one embodiment of the present invention, the outer peripheral wall of the inner valve body 120 is provided with a radially protruding abutment boss 122b, and the abutment member 210 is axially fitted with a baffle 300. An elastic member 500 abuts between the baffle 300 and the abutment boss 122b. It is understood that the function of the elastic member 500 is to provide a restoring force, enabling the abutment member 210 to automatically return to its initial position. By abutting the elastic member 500 between the baffle 300 and the abutment boss 122b, the restoring force of the elastic member 500 can be effectively utilized to ensure that the abutment member 210 is stably held in a specific position. When a control signal is triggered, the abutment member 210 moves axially under the protection of the baffle 300. The elastic member 500 provides the necessary restoring force, allowing the abutment member 210 to quickly return to its initial position after the control signal is released.

[0065] Reference Figure 1 and Figure 2 According to one embodiment of the present invention, the water circuit control system 10 further includes a drive assembly 600, with one end of the abutment member 210 extending from the inner valve cavity 121 and movably abutting against the drive assembly 600. It is understood that the drive assembly 600 can drive the abutment member 210 to move axially, thereby controlling the opening and closing of the valve port 123b. Through abutting against the drive assembly 600, the abutment member 210 can receive power from the drive assembly 600, achieving precise axial movement. Optionally, the drive assembly 600 can take various forms, such as an electric motor, a pneumatic device, or a hydraulic system. A suitable drive method can be selected to drive the abutment member 210 according to the needs of the actual application.

[0066] Reference Figure 4 and Figure 5 According to one embodiment of the present invention, the abutment member 210 includes an abutment end 211 and a pressing end 212 disposed opposite to each other along the axial direction of the outer valve body. The pressing end 212 extends from the inner valve cavity 121 and movably abuts against the drive assembly 600 to drive the abutment end 211 to move along the axial direction of the outer valve body, thereby opening the valve opening / closing port 123b. It is understood that when the drive assembly 600 receives a control signal, it drives the pressing end 212 to move. The movement of the pressing end 212 further drives the abutment end 211 to move along the axial direction of the outer valve body. The movement of the abutment end 211 changes the opening degree of the valve opening / closing port 123b, thereby realizing the opening or closing of the water passage. This allows the water passage control system 10 to perform precise control according to actual needs, improving the system's flexibility and adaptability.

[0068] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
