They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0033] The utility model discloses a water softening valve assembly, which can be used in a water softening device, such as a household water softener, to achieve control of the water path in the water softening device. Figures 1 to 4As shown, the soft water valve assembly includes a connector, a soft water valve 300, and a hydroelectric generator 200. The soft water valve 300 includes a valve body with a valve port. The hydroelectric generator 200 is detachably connected between the valve port and the connector. Water flowing through the hydroelectric generator 200 enables the hydroelectric generator 200 to generate electricity. The hydroelectric generator 200 is electrically connected to the electronic control components of the soft water valve 300 to power the electronic control components. The connectors here can be the water inlet connector 100, the water outlet connector 800, or other connectors through which water flows, such as a waste connector. For ease of description, the following description uses the water inlet connector 100 as an example.

[0034] The water inlet connector 100 is used to connect to a raw water source, allowing raw water from the raw water source to enter the soft water valve assembly through the water inlet connector 100. The water inlet connector 100, the hydroelectric generator 200, and the soft water valve 300 are sequentially connected. The valve body of the soft water valve 300 has an inlet valve port and an outlet valve port. The hydroelectric generator 200 is detachably connected between the inlet valve port and the water inlet connector 100. The hydroelectric generator 200 is electrically connected to the electronic control component of the soft water valve 300 to power the electronic control component. It should be noted that the power supply to the electronic control component here can be directly supplied by the hydroelectric generator 200 or by first storing the electricity generated by the hydroelectric generator 200 in an energy storage battery, which is then used to power the electronic control component.

[0035] Compared to prior art soft water valves that directly use batteries or external AC power, the soft water valve assembly provided by the present invention forms a raw water channel for raw water flow between the water inlet connector 100, the hydroelectric generator 200, and the soft water valve 300. As the raw water flows through the raw water channel, it passes through the hydroelectric generator 200, enabling the hydroelectric generator 200 to convert the potential energy of the water flow into electrical energy, which is then transferred to the electronic control components of the soft water valve 300. This makes the soft water valve 300 convenient to use and highly stable. Furthermore, because the hydroelectric generator 200 is directly mounted at the water inlet port of the soft water valve 300, it is easy to assemble and disassemble, and does not require major structural modifications to the soft water valve 300. This soft water valve assembly achieves the goal of generating electricity using water, solving the problems of energy shortages, the lack of external power supply, and the limited energy of battery power.

[0036] It should be noted that different power supply methods can be selected according to the amount of power generated by the hydroelectric power generation mechanism 200. When the power generation of the hydroelectric power generation mechanism 200 is small, it can be directly supplied to one or more electronic control components of the soft water valve 300 for use; when the power generation of the hydroelectric power generation mechanism 200 is large, the electricity generated by the hydroelectric power generation mechanism 200 can be converted by hardware and software and stored in the energy storage battery 410, and the energy storage battery 410 is used to power the electronic control components of the soft water valve 300. The process of power conversion is existing technology and will not be described in detail here.

[0037] like Figure 3 As shown, the water inlet connector 100 includes a first plug-in portion 101, a stopper portion 102, and a first threaded portion 103, which are sequentially connected. The first threaded portion 103 is used to connect to an external raw water source, such as a tap water pipe. The first threaded portion 103 enables the water inlet connector 100 to achieve a threaded connection with the raw water source, providing high stability and easy assembly and disassembly. The first plug-in portion 101 is used to be inserted into the hydroelectric power generation mechanism 200, thereby achieving plug-in connection with the hydroelectric power generation mechanism 200. The radial dimension of the stopper portion 102 is greater than the radial dimension of the first plug-in portion 101. A first stopper surface 104 is formed between the stopper portion 102 and the first plug-in portion 101. The first stopper surface 104 abuts against the end of the hydroelectric power generation mechanism 200 to limit the insertion depth of the water inlet connector 100 into the hydroelectric power generation mechanism 200.

[0038] The valve body of the soft water valve 300 includes a valve shell, a valve core and a driving mechanism. The valve core is installed in the valve shell and can move in the valve shell. The driving mechanism is used to drive the valve core to move in the valve shell. The movement of the valve core can realize the switching of the water path formed in the valve body.

[0039] In some embodiments, the drive mechanism includes a DC motor 500, a gear assembly, and a screw-nut mechanism. The gear assembly includes a first gear 610 and a second gear 620 that mesh with each other. The screw-nut mechanism includes a screw and a nut block threaded onto the screw. The motor shaft of the DC motor 500 is connected to the first gear 610, the second gear 620 is connected to the screw, and the valve core is connected to the nut block. Driven by the DC motor 500, the first gear 610 rotates, and the first gear 610 and the second gear 620 mesh, driving the second gear 620 to rotate. The second gear 620 drives the screw to rotate, and the nut block moves along the axial direction of the screw, thereby causing the valve core to move.

[0040] In one embodiment, the electric control component of the soft water valve 300 includes a DC motor 500 , and the electric energy generated by the hydroelectric generating mechanism 200 can power the DC motor 500 .

[0041] In one embodiment, the water softener 300 further includes an infrared sensor for detecting the number of rotations of the gear member. The electronic control component includes the infrared sensor, and the electrical energy generated by the hydroelectric generator 200 can power the infrared sensor. It should be noted that the gear member can be the first gear 610 or the second gear 620. The infrared sensor includes a transmitter and a receiver. Light emitted by the transmitter is reflected by a reflective sheet provided on the first gear 610 or the second gear 620 and then received by the receiver. Each reception by the receiver represents one rotation of the gear member.

[0042] The soft water valve 300 also includes a microswitch for limiting the movement of the valve core. The electronically controlled components include the microswitch, and the electricity generated by the hydroelectric generator 200 can power the microswitch. Optionally, multiple microswitches are provided. It should be noted that all electrically controlled components in the soft water valve 300 are electronically controlled components and are not limited to the DC motor 500, infrared sensor, and microswitch.

[0043] Continue to refer to Figure 3 As shown, the hydroelectric generating mechanism 200 includes a mounting tube 210, an impeller rotor assembly 220, and an induction coil assembly 230. The mounting tube 210 serves as the outer shell of the hydroelectric generating mechanism 200. The first plug-in portion 101 of the water inlet connector 100 can be inserted into one of the ports of the mounting tube 210, and the end surface of the mounting tube 210 can abut against the first stop surface 104. The impeller rotor assembly 220 is disposed within the mounting tube 210. Under the influence of water flow, portions of the impeller rotor assembly 220 can rotate, thereby enabling the induction coil assembly 230 to generate electrical energy through the principle of electromagnetic induction.

[0044] In some embodiments, the mounting tube 210 and the water inlet connector 100 are connected by a first clamping ring 910. Specifically, a first annular groove is provided circumferentially at one end of the mounting tube 210, and a first through-hole is provided through the bottom of the first annular groove. The first clamping ring 910 includes a first ring body and a first clamping protrusion provided on the inner side of the first ring body. A second annular groove is provided circumferentially on the first plug-in portion 101 of the water inlet connector 100. When the first clamping ring 910 is used to clamp the mounting tube 210 and the water inlet connector 100, the first ring body is placed in the first annular groove, and the first clamping protrusion is inserted into the second annular groove through the first through-hole. This can improve the connection strength between the mounting tube 210 and the water inlet connector 100 and achieve axial limitation of the mounting tube 210 and the water inlet connector 100. Optionally, the first clamping ring 910 is a C-type clamping ring.

[0045] In some embodiments, a stop ring is formed within the mounting tube 210. The first plug-in portion 101 of the water inlet connector 100 is inserted into the mounting tube 210. The impeller rotor assembly 220 is disposed within the mounting tube 210 and is positioned between the end face of the water inlet connector 100 and the stop ring. Specifically, a stepped hole is formed within the mounting tube 210. The stepped hole includes a first hole and a second hole connected in a stepped manner. The aperture of the first hole is larger than the aperture of the second hole. The first plug-in portion 101 of the water inlet connector 100 is inserted into the first hole. A stop ring is formed at the junction of the first and second holes, and one end of the impeller rotor assembly 220 rests on the stop ring.

[0046] In some embodiments, the mounting tube 210 and the valve housing of the water softener 300 are pluggable and mated, and the end of the mounting tube 210 away from the water inlet connector 100 can be inserted into the water inlet port of the water softener 300, thereby achieving plug-in connection. Specifically, the mounting tube 210 includes a tube body 211 and a second plug-in portion 212, which are interconnected. The outer diameter of the tube body 211 is larger than the outer diameter of the second plug-in portion 212. A second limit surface is formed on the outer side of the connection between the tube body 211 and the second plug-in portion 212. The second plug-in portion 212 is configured to be inserted into the water inlet port. The second limit surface is configured to abut against the end face of the valve port of the water softener 300, thereby limiting the insertion depth of the second plug-in portion 212 into the water inlet port. In addition, the first hole is formed in the tube body 211, and the second hole is formed in the second plug-in portion 212, that is, the inner diameter of the tube body 211 is larger than the inner diameter of the second plug-in portion 212, and the aforementioned stop ring surface is formed on the inner side of the connection between the tube body 211 and the second plug-in portion 212.

[0047] Furthermore, after being plugged into and mated, the mounting tube 210 and the valve housing of the water softener 300 are also connected via a second retaining ring 920. Specifically, a third annular groove is circumferentially defined on the other end of the mounting tube 210. The second retaining ring 920 includes a second ring body and a second retaining protrusion disposed within the inner portion of the second ring body. The valve housing of the water softener 300 is circumferentially defined by a fourth annular groove, with at least one second through-hole extending through the bottom of the fourth annular groove. When the second retaining ring 920 is used to connect the mounting tube 210 and the water softener 300, the second ring body is placed within the fourth annular groove, and the second retaining protrusion is inserted through the second through-hole into the third annular groove. This improves the connection strength between the mounting tube 210 and the water softener 300 and ensures axial positional restraint between the mounting tube 210 and the water softener 300. Optionally, the second retaining ring 920 is a C-shaped retaining ring.

[0048] Continue to refer to Figure 3 As shown, in some embodiments, the impeller rotor assembly 220 includes a first bracket 221, an impeller rotor 222 and a second bracket 223. The first bracket 221 and the second bracket 223 are spaced apart in the mounting tube 210, and the impeller rotor 222 is rotatably connected between the first bracket 221 and the second bracket 223.

[0049] In some embodiments, a flow guiding structure is provided on at least one of the first bracket 221 and the second bracket 223. Optionally, the flow guiding structure is a conical structure, which has a good flow guiding effect.

[0050] Optionally, the first bracket 221 includes a first frame body and a first conical guide structure 2211. The first bracket 221 is arranged on a side close to the water inlet connector 100. A plurality of first water holes are circumferentially provided on the first frame body. The first guide structure 2211 is arranged at the center of the first bracket 221, and the tip of the first guide structure 2211 faces the water inlet connector 100.

[0051] The second bracket 223 includes a second frame and a conical second flow-guiding structure 2231. The second bracket 223 is arranged on a side close to the soft water valve 300. A plurality of second water holes are provided on the second frame along the circumference. The second flow-guiding structure 2231 is arranged at the center of the second bracket 223, and the tip of the second flow-guiding structure 2231 is facing the soft water valve 300.

[0052] Impeller rotor 222 comprises an impeller, a rotor, and a rotor shaft. The impeller is circumferentially provided with multiple third water holes. A rotating shaft hole for the rotor shaft is located at the center of the impeller. The rotor shaft is rotatably connected to a first shaft hole in the first frame and a second shaft hole in the second frame, respectively. The impeller also has a rotor mounting position for mounting the rotor. The impeller and rotor rotate at high speed under the influence of water flow, and the rotor cuts through magnetic lines of force to generate electricity. Optionally, the impeller is manufactured using an injection molding process.

[0053] Continue to refer to Figure 4 As shown, in some embodiments, at least a portion of the induction coil assembly 230 is injection molded within the mounting tube 210. Optionally, the induction coil assembly 230 and the impeller rotor assembly 220 are disposed radially opposite each other in the mounting tube 210. The mounting tube 210 is a tubular structure formed using an injection molding process. During the manufacture of the mounting tube 210, the induction coil assembly 230 is directly placed within an injection mold, and then the molding material is poured in, thereby integrating the induction coil assembly 230 with the mounting tube 210. Compared with the prior art in which the induction coil assembly is arranged inside the mounting tube, resulting in poor waterproofness and even affecting the normal generation of electric energy, and the induction coil assembly is arranged outside the mounting tube, and an additional positioning structure needs to be set during assembly to achieve the positioning of the induction coil assembly, in an embodiment of the present utility model, by integrating the induction coil assembly 230 and the mounting tube 210 through an injection molding process, not only can the waterproofness of the induction coil 231 be improved, so that electromagnetic induction can be carried out normally, but also the process of positioning and assembling the induction coil assembly 230 during the assembly process is omitted, thereby simplifying the process and eliminating the need to set a positioning structure for positioning the induction coil assembly 230, thereby simplifying the structure.

[0054] In some embodiments, the main body 211 of the mounting tube 210 includes a tube body and an annular protrusion 2111 extending outwardly from the circumference of the tube body. At least a portion of the induction coil assembly 230 is injection-molded within the annular protrusion 2111. The annular protrusion 2111 thickens a portion of the tube wall of the main body 211, providing sufficient space for the injection-molded induction coil assembly 230.

[0055] In some embodiments, the induction coil assembly 230 includes an induction coil 231 and an output wire 232 . The induction coil 231 is injection-molded in the annular protrusion 2111 , and a portion of the output wire 232 is located outside the mounting tube 210 .

[0056] Continue to refer to Figure 1 As shown, the soft water valve assembly further includes an energy storage mechanism 400, which is electrically connected to the hydroelectric generating mechanism 200. The electrical energy generated by the hydroelectric generating mechanism 200 can be stored in the energy storage mechanism 400. The energy storage mechanism 400 is also electrically connected to the electronic control component. Optionally, the energy storage mechanism 400 includes a storage battery 410 capable of repeated charge and discharge, and an electronic control board 420 capable of processing the electrical energy generated by the hydroelectric generating mechanism 200. The electrical energy processed by the electronic control board 420 can be stored in the storage battery 410.

[0057] Continue to refer to Figure 1 As shown, the soft water valve assembly also includes a mounting bracket 700. The soft water valve 300 is mounted on one side of the mounting bracket 700, and the electrical control board 420 is mounted on the other side of the mounting bracket 700. One end of the output wire 232 of the hydroelectric generator 200 is plugged into a terminal on the electrical control board 420. Optionally, the energy storage battery 410 and the electrical control board 420 are located on the same side of the mounting bracket 700 to improve structural compactness. Furthermore, since the hydroelectric generator 200 is mounted directly on the water inlet of the soft water valve 300, electrical connections between the hydroelectric generator 200, the electrical control board 420, and the energy storage battery 410 can be achieved using relatively short wires. This arrangement simplifies wiring, improves aesthetics, and enhances electrical safety.

[0058] The soft water valve assembly provided by the utility model has the following advantages:

[0059] 1. The soft water valve assembly installs the hydroelectric power generation mechanism 200 at the water inlet joint 100. When the user uses water, the hydroelectric power generation mechanism 200 can use the potential energy of the water flow to drive the impeller rotor 222 to rotate to generate electricity. The water flow power generation mechanism provides electricity without the need for an external power adapter, solving the problem of power supply-limited installation scenarios and making the product design simple.

[0060] 2. The soft water valve assembly is internally provided with a cyclically chargeable and dischargeable energy storage battery 410. The energy storage battery 410 stores the electric energy generated by the hydroelectric generating mechanism 200. When the soft water valve 300 requires software control, the energy storage battery 410 can release the required electric energy.

[0061] The present invention also discloses a water softening device comprising a water softening mechanism and the aforementioned water softening valve assembly. The water softening valve 300 has a water outlet valve port that communicates with the water softening mechanism. The water softening valve 300 of the water softening device is not only convenient but also highly safe in terms of electrical power usage. It should be noted that the specific structure of the water softening mechanism is prior art and will not be described in detail here.

[0062] Optionally, the water softening device further includes a water outlet connector 800, which is mounted at the outlet valve port and can be connected to the water softening mechanism. In one embodiment, the water outlet connector 800 is pluggable and mated with the valve housing and is engaged with the valve housing via a third retaining ring 930. In one embodiment, the water outlet connector 800 includes a second threaded section.

[0063] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
