[0002] Currently, with the improvement of people's living standards, people have increasingly higher requirements for the quality of bathing water, and they filter the bathing water to achieve the goal of healthy bathing. In order to meet the requirements of filtering bathing water, filter cartridges are usually installed to treat the incoming water.

[0003] Softening water to create soft water is a common water treatment method, requiring a water softener in the home. In practice, bathing water often needs softening to improve the bathing experience. However, water softeners are generally bulky and cannot be installed directly in the bathroom, and they soften the water throughout the entire house during operation.

[0004] Therefore, the technical problem to be solved by this invention is how to design a compact and convenient bathroom installation device. Summary of the Invention

[0105] This embodiment provides a wall-mounted bathing device, such as... Figures 24-30 As shown, the wall-mounted bathing equipment includes:

[0106] The housing 100 is provided with an inlet pipe 101 and an outlet pipe 102. An installation space is formed inside the housing 100, and a first mounting seat 103 and a second mounting seat 104 are provided in the installation space.

[0107] The water valve module has an inlet port 2101, an outlet port 2102, an external port 2103, and a suction port; wherein, the water valve module is composed of a housing 210 and a temperature control valve core 220, a water circuit control valve core 230, and a regeneration valve core disposed on the housing 210.

[0108] Water treatment filter element 240 is used to treat the water flowing into the water inlet pipe 101 and output it from the water outlet pipe 102.

[0109] The salt tank is equipped with a suction tube;

[0110] The salt tank, the water valve module, and the water treatment filter element 240 are all housed inside the housing 100. The valve module is mounted on the first mounting base 103, and the water treatment filter element 240 is mounted on the second mounting base 104. The inlet pipe 101 is connected to the inlet interface 2101, the outlet pipe 102 is connected to the outlet interface 2102, the water treatment filter element 240 is connected to the outer interface 2103, and the suction pipe is connected to the suction port. The housing 100 is used to hang on the inlet pipe 101 and / or the outlet pipe 102.

[0111] Specifically, to meet the installation requirements of a bathroom, a wall-mounted housing 100 is adopted, which is suspended from the bathroom wall via an inlet pipe 101 and / or an outlet pipe 102. The water valve module and the water treatment filter element 240 are centrally installed within the housing 100. The water valve module and the water treatment filter element 240 constitute the water treatment device 200 in this embodiment. The specific structural forms of the water valve module and the water treatment filter element 240 are not detailed here.

[0112] During installation in a user's home, the inlet pipe 101 is connected to the user's home water network. There is usually a water supply outlet on the wall of the user's home, and the inlet pipe 101 is installed on the water supply outlet. Similarly, the outlet pipe 102 is connected to the water pipe of the user's home water terminal.

[0113] The following explanation uses the water inlet pipe 101 as an example to illustrate the function of the housing 100.

[0114] The water inlet pipe 101 is connected to the water supply pipe in the wall of the user's home. The housing 100 is hung on the wall through the water inlet pipe 101. The water valve module and water treatment filter element 240 in the housing 100 are fixedly installed in the housing 100 through the corresponding mounting brackets.

[0115] The housing 100 is mounted on the wall via the inlet pipe 101 or the outlet pipe to meet the requirements of wall installation. Meanwhile, the water valve module and the water treatment filter element 240 are centrally installed in the housing 100 to achieve a compact design and meet the requirements of unified and rapid on-site installation.

[0116] In some embodiments, the housing 100 has a flat overall structure. This flat structure allows the housing 100 to be mounted on a wall, enabling it to fit snugly against the wall and utilize the wall space to create internal installation space for the water valve module and water treatment filter 240. Furthermore, the flat structure of the housing 100 reduces the amount of usable bathroom space it occupies, minimizing the risk of users bumping into it during showering. Additionally, the integrated water valve module in the housing 100 allows for wall-mounted installation at a height suitable for user operation, thus utilizing the existing space where a mixing valve is installed.

[0117] In one embodiment of this application, the water inlet pipe 101 passes through the back plate of the housing 100 and extends to the outside of the housing 100.

[0118] Specifically, the water inlet pipe 101 extends from the back panel of the housing 100 to connect to the water supply pipe on the wall of the user's home. Typically, the water inlet pipe 101 is arranged horizontally, which is more conducive to supporting the housing 100 and the water valve module and water treatment filter 240 inside the housing 100. Furthermore, since the water entering the water valve module is generally divided into cold water and hot water, water inlet pipes 101 can be arranged on both sides of the housing 100, with one water inlet pipe 101 for transporting cold water and the other for transporting hot water.

[0119] In one embodiment, to facilitate on-site installation by operators, the water inlet pipe 101 includes a first pipe body 1011 and a second pipe body 1012. The first pipe body 1011 is provided with an external thread portion 1013. The axis of the external thread portion 1013 is offset from the axis of the first pipe body 1011. The first pipe body 1011 is sealed and inserted into the second pipe body 1012. The external thread portion 1013 is located outside the housing 100. The second pipe body 1012 is connected to the water inlet interface 2101.

[0120] Specifically, during the actual assembly process, due to differences in home decoration and construction, the distance between the two pipe openings of the external water pipes that transport hot and cold water varies. By setting the external thread 1013 of the first pipe body 1011 to an off-axis arrangement, and then connecting the external thread 1013 to the pipe opening on the wall, and by rotating it at an appropriate angle, the distance between the two first pipe bodies 1011 can meet the installation distance between the two second pipe bodies 1012 fixedly installed on the housing 100. This allows for convenient and quick on-site installation and improves installation versatility.

[0121] The first tube 1011 and the second tube 1012 are installed by insertion. After adjusting the installation position of the first tube 1011, the first tube 1011 is inserted into the corresponding second tube 1012 to complete the assembly.

[0122] In another embodiment, in order to ensure a secure and reliable connection between the first tube 1011 and the second tube 1012, the outer diameter of the section of the first tube 1011 inserted into the second tube 1012 gradually increases from the outside to the inside. The tube wall of the second tube 1012 is provided with screw holes, and a locking screw 1014 is threaded into the screw holes. The locking screw 1014 abuts against the outer tube wall of the first tube 1011.

[0123] Specifically, during installation in a user's home, after the two first tubes 1011 are installed and positioned, the housing 100 is connected to the first tubes 1011 on the wall via the second tube 1012. Furthermore, after inserting the first tubes 1011 into the second tubes 1012 and adjusting the distance between the housing 100 and the wall, the first tubes 1011 are secured to the second tubes 1012 using locking screws 1014.

[0124] Since the outer wall of the first tube 1011 has a variable diameter structure, the larger the outer wall diameter of the first tube 1011 inserted into the second tube 1012, the more reliable the connection between the first tube 1011 and the second tube 1012 can be improved by tightening the locking screw 1014 so that the end of the locking screw 1014 abuts against the outer wall of the first tube 1011.

[0125] Meanwhile, the first tube 1011 and the second tube 1012 are connected by using the locking screw 1014 to cooperate with the outer tube wall of the first tube 1011, and the casing 100 can be tightly attached to the wall for installation by using the variable diameter structure of the outer tube wall of the first tube 1011.

[0126] In addition, to facilitate the operator's operation of the locking screw 1014, an operating hole 130 can be provided on the housing 100, with the operating hole 130 arranged opposite to the locking screw 1014. Specifically, during actual installation, after adjusting the position between the first tube 1011 and the second tube 1012, the locking screw 1014 can be used to tighten the first tube 1011 and the second tube 1012. Since the second tube 1012 is located inside the housing 100, the operator can insert a screwdriver into the operating hole 130 to tighten the locking screw 1014.

[0127] Regarding the water treatment filter element 240 and the brine tank, two water treatment filter elements 240 are distributed on both sides of the brine tank. Since the water treatment filter element 240 is typically cylindrical, in order to fully utilize the space within the housing 100 to increase the volume of the brine tank, recessed structures (not marked) are formed on both sides of the brine tank, and the water treatment filter element is located in the corresponding recessed structure on the side.

[0128] In some embodiments, the housing 100 includes a front cover 1, a rear cover 2, and an upper cover 3. The front cover is disposed on the rear cover 2, and an installation cavity is formed between the front cover and the rear cover 2. The upper cover 3 is disposed at the upper end of the rear cover 2.

[0129] To facilitate the installation of the salt tank, a hook 51 is provided on the back of the salt tank, and a hanging hole 140 is provided on the back of the rear shell 2, and the hook is hung in the hanging hole 140.

[0130] Specifically, when installing the salt tank onto the housing 100, the front cover is opened, and the salt tank is inserted into the hanging hole 140 via the hook, so that the salt tank is suspended in the housing 100. Additionally, if necessary, the salt tank can be further secured to the housing 100 with screws.

[0131] In some embodiments, since salt needs to be added to the salt tank periodically, a filling port (unmarked) is provided on the front cover to facilitate the user's salt-adding operation. The filling port is located above the salt tank.

[0132] Specifically, the top of the salt tank has an open structure. When salt needs to be added to the salt tank, the user can add salt into the salt tank inside the housing 100 through the filling port without opening the housing 100.

[0133] In some embodiments, the filling port is provided with an operable door 11. The lower part of the door 11 is hinged to the housing 100, and the inner walls of the door 11 are provided with raised guide ribs 12 on both sides. The two guide ribs 12 gradually move downwards and converge, and the lower ends of the two guide ribs 12 form a discharge port.

[0134] Specifically, in actual operation, after the user opens the door 11, the door 11 is arranged outwards at an angle from bottom to top, and the user can introduce salt into the salt tank inside the housing 100 through the door 11.

[0135] During the pouring of salt, the guide ribs 1212 arranged on both sides of the door 11 can guide the salt to fall accurately into the salt tank below.

[0136] Based on the above technical solutions, optional ones include, for example: Figure 27-29 As shown, for the fixed installation method of the water treatment filter element 240, in order to reliably support the water treatment filter element 240 and at the same time meet the requirements of easy disassembly and assembly, a support part 120 can be configured in the housing 100; the water treatment filter element 240 is inserted into the external interface 2103 through the insertion water pipe at its end, and the other end of the water treatment filter element 240 abuts against the support part 120.

[0137] Specifically, during the installation of the water treatment filter element 240, after the water treatment filter element 240 is installed on the external interface 2103 through the water pipe, the other end of the water treatment filter element 240 abuts against the support part 120 configured on the housing 100, thereby the other end of the water treatment filter element 240 can also be supported by the support part 120.

[0138] The two ends of the water treatment filter element 240 are supported and fixed respectively, which can effectively reduce the occurrence of the water treatment filter element 240 falling off due to shaking during use, thereby improving the reliability of use. In addition, during the installation or removal of the water treatment filter element 240, the water treatment filter element 240 can be easily detached from the support part 120 or abutted against the support part 120 by pushing or pulling the water treatment filter element 240, thereby meeting the requirements of easy disassembly and assembly.

[0139] In one embodiment, the support portion 120 is an elastic plate disposed on the housing 100, and one end of the elastic plate is disposed on the housing 100.

[0140] Specifically, the support part 120 adopts an elastic plate, which gives the support part 120 a certain degree of elasticity. In this way, when the water treatment filter element 240 is installed, the end of the water treatment filter element 240 abuts against the elastic plate, so that the elastic plate undergoes a certain deformation, thereby using the elastic plate to provide reliable support for the water treatment filter element 240.

[0141] During disassembly, the elasticity of the elastic plate is overcome while still meeting the requirement of easy disassembly of the water treatment filter element 240.

[0142] In one embodiment, the surfaces of the elastic plate that contact the end of the water treatment filter element 240 form an inclined surface 121 and a support surface 122 connected in sequence.

[0143] Specifically, the inclined surface 121 facilitates the movement of the end of the water treatment filter element 240 during installation, and after the water treatment filter element 240 is installed in place, the end of the water treatment filter element 240 abuts against the support surface 122. In addition, to facilitate processing and reduce manufacturing costs, the elastic plate and the housing 100 are an integral structure.

[0144] In other embodiments, in order to further limit the end of the water treatment filter element 240 that contacts the support portion 120, limiting portions 123 are also provided on both sides of the support portion 120, and the filter element is located between the two limiting portions 123.

[0145] Specifically, the limiting portions on both sides of the support portion 120 form a limiting space, which can restrict the water treatment filter element 240 to the end position of contact with the support portion 120 within the limiting space, thereby improving installation reliability.

[0146] In some embodiments, at least one second mounting base 104 may be provided on the housing 100 along the length of the filter element, and a recess is formed on the second mounting base 104, in which the water treatment filter element 240 is located.

[0147] Specifically, after the two ends of the water treatment filter element 240 are fixedly installed through the external interface 2103 and the support part 120 respectively, the water treatment filter element 240 is provided with at least one second mounting seat 104 in its length direction. The recess formed by the second mounting seat 104 can further position and support the middle area of ​​the water treatment filter element 240, which is more conducive to improving the installation reliability.

[0148] Example 1, as Figures 1-3 As shown, the water treatment device in this embodiment is used to soften flowing water and also to control the flow rate and temperature. The water treatment device 200 includes:

[0149] The outer casing 210 is provided with a water inlet 2101, a water outlet 2102, an external interface 2103, a liquid suction port and a waste discharge port. The outer casing 210 is also provided with a first installation space (not shown), a second installation space (not shown) and a third installation space. The interior of the outer casing 210 is also provided with multiple connection channels 2104.

[0150] Temperature control valve core 220 is disposed in the first installation space and is used to control the outlet water temperature of the water treatment device 200.

[0151] Water circuit control valve core 230, which is disposed in the second installation space;

[0152] A regeneration valve core is disposed within the third mounting space;

[0153] Water treatment filter element 240 is used to treat the water flowing through it.

[0154] A salt tank, wherein the salt tank is equipped with a suction tube;

[0155] The first installation space, the second installation space, and the third installation space are interconnected through the connection channel, and the water inlet, the water outlet, the external interface, and the liquid suction port are connected to the corresponding connection channel.

[0156] The temperature control valve core controls the outlet water temperature of the water treatment device, the water circuit control valve core controls the opening and closing of the connection channel between the inlet, the outlet and the external interface, the regeneration valve core controls the opening and closing of the connection channel between the inlet, the external interface, the suction port and the waste discharge port, and the suction pipe is connected to the suction port.

[0157] Specifically, for the outer casing 210, its water inlet 2101 and water outlet 2102 are respectively connected to the external water pipe network. For example, the water inlet 2101 is connected to the water supply end of the external water pipe network, while the water outlet 2102 is connected to the water consumption end of the external water pipe network.

[0158] In the actual assembly process, the temperature control valve core 220 is installed in the first installation space, the water circuit control valve core 230 is installed in the second installation space, and the regeneration valve core 42 is installed in the third installation space. The three installation spaces are connected by a connection channel 2104 provided inside the housing 210. Since the connection channel 2104 is built into the housing 210 and the first, second, and third installation spaces are pre-connected according to the design requirements, during assembly, only the temperature control valve core 220, the water circuit control valve core 230, and the regeneration valve core need to be installed in their respective installation spaces to complete the assembly. This reduces the need to connect the valve cores one by one through water pipes during the assembly process, thus simplifying the assembly process.

[0159] In addition, when installing in a user's home, the water inlet 2101, water outlet 2102, and external interface 2103 are also connected to the corresponding installation space through the internal connection channel 2104, so that during on-site assembly, only the water pipe of the external water supply pipe needs to be connected to the water inlet 2101 and the water outlet 2102.

[0160] As for the water treatment filter element 240, it can be connected to the external interface 2103 at the factory stage, or it can be connected to the external interface 2103 during the user's home assembly.

[0161] Water treatment filter element 240 can achieve water softening treatment. Here, we will not limit or elaborate on the specific performance of water treatment filter element 240.

[0162] In some embodiments, the water flow input to the inlet port 2101 can have multiple flow paths depending on the state of different valve cores.

[0163] As for the water circuit control valve core 230, it can control the opening and closing of the water circuit entering the temperature control valve core, and can further control the water flow rate as needed. The specific flow path is as follows.

[0164] For example, water entering through inlet 2101 flows sequentially through water control valve core 230, temperature control valve core 220, water treatment filter element 240, and is output from outlet 2102. Specifically, water supplied by the external water supply network enters through inlet 2101, first flows through water control valve core 230 to facilitate control of water flow; then, the water flows into the temperature control valve to regulate the temperature; the water at the regulated temperature enters water treatment filter element 240 for water quality treatment, and finally passes through water control valve core 230 to be output from outlet 2102 to the water user end of the water supply network.

[0165] Alternatively, the water entering through the inlet port 2101 is sequentially passed through the temperature control valve core 220, the water circuit control valve core 230, the water treatment filter element 240, and the water circuit control valve core 230 before being output from the outlet port 2102.

[0166] Alternatively, the water entering through the inlet port 2101 flows sequentially through the temperature control valve core 220, the water treatment filter core 240, and the water circuit control valve core 230 before being output from the outlet port 2102.

[0167] The regeneration valve core is used to control the flow path between the water treatment filter element and the brine tank, and the specific flow path is as follows.

[0168] With the regeneration valve core in the conductive state, the water flowing into the inlet sequentially passes through the regeneration valve core, the water treatment filter element, and exits through the waste outlet. Specifically, water supplied by the external water supply network enters through the inlet 2101, first flowing through the regeneration valve core to carry the salt solution in the salt tank out and into the water treatment filter element. The salt solution is used to regenerate the ion exchange resin in the water treatment filter element. During the regeneration process, the waste liquid flowing out of the water treatment filter element is discharged through the waste outlet.

[0169] In some embodiments, the housing is further provided with the water inlet, which is connected to the salt tank, and the regeneration valve core is also used to control the opening and closing of the connection channel between the water inlet and the water inlet.

[0170] Specifically, the regeneration valve core, in addition to controlling the opening and closing of the flow path between the water treatment filter element and the brine tank, also has the function of controlling the replenishment of water to the brine tank. Under the replenishment state, the specific flow path is as follows.

[0171] With the regeneration valve core in the conducting state, the water entering through the inlet flows sequentially into the salt tank via the regeneration valve core.

[0172] In one embodiment of this application, as Figures 4-6 As shown, the connecting channel 2104 arranged in the housing 210 is built into the housing 210. However, due to the limited internal space of the housing 210 and the need to meet the requirements for connecting different water flow paths, in order to reduce the processing difficulty of forming the connecting channel 2104 in the housing 210, the connecting channel 2104 is configured according to its position inside the housing 210 and the requirements for water flow connections, such as... Figure 6 As shown, part of the connecting channel 2104 is a complete water channel directly formed in the outer shell 210, while the remaining part of the connecting channel 2104 needs to realize the water flow through bends. For this type of connecting channel 2104, it is formed in the outer shell 210 by a split connection.

[0173] Specifically, such as Figure 5 As shown, the connecting channel 2104 includes two main waterways 21041 and a secondary waterway 21042. The two main waterways 21041 are arranged in parallel and staggered. The secondary waterway 21042 is staggered with the two main waterways 21041 and connects to the two main waterways 21041 respectively. One end of the secondary waterway 21042 is located on the outer surface of the housing 210 and is provided with a plug 21043. The two main waterways 21041 are not collinear, such as being staggered vertically or horizontally, while the secondary waterway 21042 connects the two main waterways 21041 to realize the bend in the connecting channel 2104 for water transportation.

[0174] Thus, in actual processing, the outer shell 210 is typically manufactured using conventional methods such as injection molding. The integral connecting channel 2104 is entirely built into the outer shell 210. For the split-design connecting channel 2104, the secondary water channel 21042 is used in conjunction with two main water channels 21041 to form the connecting channel 2104. One end of the secondary water channel 21042 is located on the surface of the outer shell 210 for easy processing. At the same time, the end of the secondary water channel 21042 is further sealed using a plug 21043.

[0175] In another embodiment of this application, the temperature control valve core 220 mainly functions to regulate the water temperature. It is preferred to use a thermostatic valve core. Correspondingly, there are two configurations for the water inlet interface 2101, namely a first sub-water inlet interface and a second sub-water inlet interface.

[0176] The first installation space is provided with inlet one (unmarked), inlet two (unmarked) and mixing outlet (unmarked). Inlet one and inlet two are arranged on one side of the thermostatic valve core, and the mixing outlet is arranged at the end of the thermostatic valve core. The thermostatic valve core is used to adjust the water inlet one and inlet two according to the water temperature of the mixing outlet.

[0177] The water flow input from the first sub-inlet interface enters the first inlet, the water flow input from the second sub-inlet interface enters the second inlet, and the water flow output from the mixed water outlet is output from the outlet interface 2102.

[0178] Specifically, the two inlet ports 2101 introduce water at different temperatures, namely hot water and cold water. The hot and cold water flow into the thermostatic valve core through inlet one and inlet two, respectively. The thermostatic valve core automatically controls the ratio of hot and cold water according to the user-adjusted outlet water temperature, and finally outputs water at the set temperature from the mixing outlet. The specific structural form of the thermostatic valve core for automatically adjusting the ratio of hot and cold water can be referred to the valve core structure of a conventional thermostatic valve, and will not be limited or elaborated here.

[0179] In addition, in order to meet the water supply requirements of the regeneration valve core, a tee (unmarked) is provided on one of the water inlet ports 2101. Water entering the water inlet port 2101 is diverted through the tee to the third installation space to supply water to the regeneration valve core.

[0180] In Example 2, the main function of the water circuit control valve core 230 is to control the on / off state of the water circuit and also to regulate the water flow. To meet the requirements of multi-water circuit cut-off control and multi-water circuit connection, such as... Figures 7-9As shown, the water circuit control valve core 230 includes a first fixed valve plate 231 and a first rotating valve plate 232. The first fixed valve plate 231 is provided with at least one first inlet / outlet group, which includes two first inlet / outlet ports 2311. The first rotating valve plate 232 is provided with a first connecting groove 2321 that cooperates with the first inlet / outlet group.

[0181] The first rotating valve plate 232 is attached to the first fixed valve plate 231 and can rotate relative to the first fixed valve plate 231. The first connecting groove 2321 selectively connects to the two first inlet and outlet ports 2311 in the corresponding first inlet and outlet group. The first inlet and outlet ports 2311 are connected to the corresponding connecting channel 2104.

[0182] Specifically, in actual use, a corresponding number of first inlet / outlet groups are set according to the number of connecting channels 2104 in the housing 210 and the requirements for on / off control between the connecting channels 2104. The on / off control of the two first inlet / outlet ports 2311 within the same first inlet / outlet group is controlled by the first rotary valve plate 232. Each first inlet / outlet port 2311 is connected to its corresponding connecting channel 2104.

[0183] When it is necessary to connect the two connecting channels 2104, the first rotating valve plate 232 rotates to connect the two first inlet / outlet ports 2311 in the same outlet group through the first connecting groove 2321, thereby connecting the two connecting channels 2104 to each other. At the same time, the water flow rate is further controlled by controlling the overlap area between the first connecting groove 2321 and the first inlet / outlet ports 2311.

[0184] When it is necessary to disconnect the two connecting channels 2104, the first rotating valve plate 232 rotates, causing the first connecting groove 2321 to disconnect from the first inlet / outlet 2311, thereby disconnecting the two connecting channels 2104.

[0185] In some embodiments, to facilitate the installation of the water circuit control valve core 230, the water circuit control valve core 230 further includes a first valve body 233, a first fixed valve plate 231 is fixedly disposed in the first valve body 233, and a first rotating valve plate 232 is rotatably disposed in the first valve body 233. The first valve body 233 is located in the second installation space.

[0186] Specifically, the first fixed valve plate 231 and the first rotating valve plate 232 are respectively installed in the first valve body 233, and then uniformly assembled into the second installation space through the first valve body 233, thereby realizing a modular design.

[0187] In another embodiment, in order to enable the first valve body 233 to be quickly and conveniently installed in the second installation space, the water circuit control valve core 230 further includes a locking sleeve 238. The locking sleeve 238 has an external thread, and the second installation space has an internal thread. The locking sleeve 238 is threadedly connected to the second installation space and abuts against the first valve body 233.

[0188] Specifically, during the actual assembly process, after the first fixed valve plate 231 and the first rotating valve plate 232 are installed into the first valve body 233, the first fixed valve plate 231 needs to be accurately connected to the connection channel 2104 in the housing 210, and the installation position of the first valve body 233 needs to be accurately matched with the connection channel 2104 in the housing 210. Therefore, the first valve body 233 is directly inserted into the second installation space using a push-fit method. After the first valve body 233 is in place, it is threaded onto the outside of the second installation space via a locking sleeve 238 to abut against the first valve body 233, ultimately achieving a secure and reliable installation of the water circuit control valve core 230 onto the housing 210.

[0189] In some embodiments, in order to make the first fixed valve plate 231 more securely installed and to facilitate the user to drive the first rotating valve plate 232 to rotate, one end of the first valve body 233 is provided with a first mounting port (unmarked), and the other end is provided with a first mounting hole (unmarked); the water circuit control valve core 230 also includes a first water distribution plate 234 and a first valve stem 235. The first water distribution plate 234 is provided with a plurality of first through holes 2341. The first water distribution plate 234 is disposed in the first mounting port. The first valve stem 235 passes through the first mounting hole and connects to the first rotating valve plate 232. The first fixed valve plate 231 is disposed on the first water distribution plate 234 and located between the first water distribution plate 234 and the first rotating valve plate 232; wherein, the first inlet and outlet ports 2311 are respectively connected to the corresponding first through holes 2341 and the connecting channel 2104.

[0190] Specifically, the first fixed valve plate 231 and the first rotating valve plate 232 are made of wear-resistant materials (such as ceramic valve plates). By configuring the first water distribution plate 234 on the outside of the first fixed valve plate 231, on the one hand, the first water inlet and outlet 2311 on the first fixed valve plate 231 can be connected to the corresponding connecting channel through the corresponding first through hole 2341. On the other hand, the first water distribution plate 234 squeezes the first fixed valve plate 231 from the outside, so that the first fixed valve plate 231 and the first rotating valve plate 232 are tightly attached together to ensure a sealed connection between the two.

[0191] One end of the first valve stem 235 is sealed and inserted into the first valve body 233 and connected to the first rotating valve plate 232, while the other end is exposed and equipped with a knob to facilitate the user to drive the first rotating valve plate 232 to rotate via the knob.

[0192] To achieve a sealed connection between the first fixed valve plate 231 and the first water distribution plate 234, a first inner sealing gasket 236 is provided on the inner side of the first water distribution plate 234. The first inner sealing gasket 236 is used to seal the outer periphery of the first through hole 2341 and the corresponding first inlet / outlet 2311. Specifically, the first inner sealing gasket 236 is provided between the first fixed valve plate 231 and the first water distribution plate 234 to seal the connection between the first through hole 2341 and the first inlet / outlet 2311. Similarly, a first outer sealing gasket 237 is provided on the outer side of the first water distribution plate 234 to seal the outer periphery of the port of the first through hole 2341 and the corresponding connecting channel 2104 located in the second installation space.

[0193] In addition, to facilitate quick and easy installation of the first inner sealing gasket 236 and the first outer sealing gasket 237, a first mounting groove (unmarked) is provided on the inner and outer surfaces of the first water distribution plate 234 around the first through hole 2341, and the first outer sealing gasket 237 and the first inner sealing gasket 236 are located in the first mounting groove. Specifically, the structure of the first mounting groove matches the shape of the sealing gasket, and during assembly, the sealing gasket is snapped into the first mounting groove.

[0194] In another embodiment, in order to position and install the first fixed valve plate 231, a first notch 2331 is provided on the edge of the first mounting port, and a first positioning protrusion 2312 is provided on the first fixed valve plate 231, the first positioning protrusion 2312 being inserted into the first notch 2331.

[0195] Specifically, during the assembly of the water control valve core 230, the first rotating valve plate 232, the first fixed valve plate 231, and the first water distribution plate 234 are sequentially inserted into the first valve body 233 through the first mounting port. The first positioning protrusion 2312 of the first fixed valve plate 231 will be engaged in the first notch 2331, so that the first fixed valve plate 231 is fixed relative to the first valve body 233 and does not rotate.

[0196] The first water distribution plate 234 is provided with a second positioning protrusion 2342, which is inserted into the first notch 2331. Similarly, when assembling the first water distribution plate 234, after the first water distribution plate 234 is installed on the first valve body 233, the second positioning protrusion 2342 will also be located in the first notch 2331, so that the first water distribution plate 234 is fixed relative to the first valve body 233 and does not rotate.

[0197] In addition, to facilitate the installation of the first water distribution plate 234 and the first fixed valve plate 231 together and improve assembly efficiency, a slot 2313 is provided on the first protrusion, and a tongue 2343 is provided on the second positioning protrusion 2342, which is inserted into the slot 2313. During assembly, the first inner sealing gasket 236 is placed between the first water distribution plate 234 and the first fixed valve plate 231, and then the tongue 2343 is inserted into the slot 2313, so as to pre-assemble the first water distribution plate 234 and the first fixed valve plate 231 together.

[0198] In one embodiment, the first water distribution plate 234 is connected to the first valve body 233 by a snap-fit ​​method. Specifically, during assembly, the first water distribution plate 234 is installed and fixed to the first valve body 233 by a snap-fit ​​method. For example, the edge of the first installation port is provided with a first buckle, and the first water distribution plate 234 is provided with a first claw, which is engaged in the first buckle.

[0199] In other embodiments, after the first valve body 233 is installed into the housing 210, in order to prevent the first valve body 233 from rotating in the housing 210 and causing incorrect water circuit connection, a positioning groove 2344 is provided on the first water distribution plate 234, and a positioning block (not shown) is provided in the second installation space, and the positioning block is inserted into the positioning groove 2344.

[0200] Specifically, after the first valve body 233 is inserted into the second installation space, the positioning block will be engaged in the positioning groove 2344, thereby positioning the first valve body 233. The cooperation between the positioning block and the positioning groove 2344 ensures that the first through hole 2341 and the connecting channel 2104 are precisely aligned, and effectively prevents the first valve body 233 from rotating, thus improving reliability.

[0201] In some embodiments, the water flow path is illustrated by taking the example of water entering through two inlet ports 2101 and sequentially passing through the water control valve core 230, the temperature control valve core 220, the water treatment filter element 240, and the water control valve core 230 before exiting through the outlet port 2102. To meet the on / off control requirements of the aforementioned water flow path, the first fixed valve plate 231 in the water control valve core 230 is equipped with three sets of outlet groups: a first sub-inlet / outlet group, a second sub-inlet / outlet group, and a third sub-inlet / outlet group.

[0202] The first sub-inlet interface is selectively connected to the first inlet through the first sub-inlet / outlet group; the second sub-inlet interface is selectively connected to the second inlet through the second sub-inlet / outlet group; the mixed water outlet is connected to the external interface 2103 through the connecting channel 2104; and the external interface 2103 is selectively connected to the outlet interface 2102 through the third sub-inlet / outlet group.

[0203] Specifically, taking the first sub-inlet port for cold water and the second sub-inlet port for hot water as an example, the cold water flows to the first inlet through the first outlet group on the first fixed valve plate 231, and the flow of cold water is controlled by opening and closing the two first inlet / outlet ports 2311 in the first sub-inlet / outlet group. Similarly, the hot water flows to the second inlet through the second outlet group on the first fixed valve plate 231, and the flow of hot water is controlled by opening and closing the two first inlet / outlet ports 2311 in the second sub-inlet / outlet group. The water that has been treated by the water treatment filter element 240 flows to the outlet port 2102 through the third outlet group on the first fixed valve plate 231.

[0204] Among them, the first inlet / outlet 2311, which is connected to the outlet interface 2102 via the connecting channel 2104, is the outlet, and the cross-sectional area of ​​the water flow at the outlet gradually increases with the direction of water flow.

[0205] Specifically, the first inlet / outlet 2311 connected to the outlet interface 2102 is designated as the outlet. Due to the size limitation of the outer casing 210, the cross-sectional area of ​​the first connecting groove 2321 is relatively small, while the cross-sectional area of ​​the water flow at the connection point between the outlet and the connecting / disconnecting part is relatively large. During the water output process, the water will diffuse outward, which can easily lead to turbulence due to abrupt changes in cross-section. By gradually increasing the cross-sectional area of ​​the outlet water flow along the direction of water flow, the water flow diffusion and turbulence caused by water flow can be reduced. Furthermore, the formation of cavities during water flow can be reduced, thereby reducing water flow noise and improving the user experience.

[0206] Preferably, such as Figure 9As shown, the outer surface of the first fixed valve plate 231 is provided with a water storage tank 2314 with the same shape as the corresponding first through hole 2341, and the outlet water outlet passes through the water storage tank 2314. Specifically, the shape of the water storage tank 2314 matches the shape of the corresponding first through hole 2341, which on the one hand ensures the reliability of the water circuit connection to reduce the occurrence of water leakage, and on the other hand, the water storage tank 2314 can further buffer the water flow. The first inlet / outlet 2311, which is used to connect with the outlet water outlet, is the inlet water outlet, and the outlet water outlet is adjacent to the inlet water outlet. A slope 2315 is formed in the water storage tank 2314, extending inclined away from the inlet water outlet. Specifically, the slope 2315 satisfies the requirement that the cross-sectional area of ​​the water flow at the outlet water outlet gradually increases with the direction of water flow, and can also guide the water flow to better distribute it to the corresponding connected first through hole 2341.

[0207] Example 3: Regarding the regeneration valve core, based on the above technical solution, the following options are available: Figure 10 - Figure 14 As shown, the regeneration valve core includes a second fixed valve plate 421 and a second rotating valve plate 422. The second fixed valve plate is provided with at least one second inlet / outlet group, which includes two second inlet / outlet ports 4211. The first rotating valve plate is provided with a second communicating groove 4221 that cooperates with the second inlet / outlet group. The edge of the first rotating valve plate is also provided with an inlet notch 4222 for water intake.

[0208] The second rotating valve plate is attached to the second fixed valve plate and can rotate relative to the second fixed valve plate. The second connecting groove selectively connects two second inlet / outlet ports in the corresponding second inlet / outlet group. The second inlet / outlet ports are connected to the corresponding connecting channel. The inlet notch is selectively connected to the second inlet / outlet ports.

[0209] Specifically, in actual use, a corresponding number of second inlet / outlet groups are configured according to the flow path on / off requirements of the regeneration valve core 42. The on / off control of the two second inlet / outlet ports in the same second inlet / outlet group is controlled by the second rotating valve plate. The second inlet / outlet ports are respectively connected to the corresponding connecting channels 2104 formed inside the housing.

[0210] In addition, the water flow entering the third installation space enters the interior of the regeneration valve core through the water inlet notch. The second connecting groove selectively connects the two second inlet and outlet ports in the corresponding second inlet and outlet group, so that the water flow entering from the water inlet notch passes through the two connected second inlet and outlet ports and finally flows through the corresponding connecting channel 2104 in the housing according to the set flow path.

[0211] The following explanation, in conjunction with the accompanying drawings, describes the different states of the regeneration valve core. For example... Figures 12-14 As shown, the solid line represents the second fixed valve plate 421, while the dashed line represents the second rotating valve plate 422.

[0212] like Figure 12 As shown, when the regeneration valve core is in the closed state, the water inlet is blocked by the second fixed valve plate, and the water flow cannot enter the second inlet / outlet 4211 provided on the second fixed valve plate 421.

[0213] like Figure 13 As shown, when the regeneration valve core is in the regeneration state, the second rotating valve plate 422 rotates by a set angle so that the water inlet notch is aligned with the regeneration valve core. Figure 13 The second inlet / outlet corresponding to the left side is connected, and simultaneously, the corresponding inlet / outlet is connected through the second connecting channel, so that the water input from the inlet gap is finally output through the second inlet / outlet connected to the water treatment filter element. Meanwhile, refer to... Figure 13 The two second inlet and outlet ports on the right side are used to connect the water outlet of the water treatment filter element and the waste outlet through the corresponding second connecting groove.

[0214] like Figure 14 As shown, when the regeneration valve core is in the state of replenishing water to the brine tank, the second rotating valve plate 422 rotates by a set angle so that the water inlet notch is aligned with the brine tank. Figure 13 The second inlet / outlet corresponding to the lower middle part is connected, and the water input from the inlet gap is output through the second inlet / outlet to the water supply port 407 and flows into the salt tank.

[0215] In some embodiments, the regeneration valve core further includes a second valve body 423, the second fixed valve plate is fixedly disposed in the second valve body, the second rotating valve plate is rotatably disposed in the second valve body, the second valve body is located in the third installation space, and a perforated hole 4231 for water inlet is provided on the circumferential wall of the second valve body.

[0216] Specifically, to facilitate the installation of the regeneration valve core in the third mounting space, the second fixed valve plate 421 and the second rotating valve plate 422 are installed in the second valve body. In this way, the valve can be installed in the third mounting space via the second valve body.

[0217] The second valve body is a sleeve structure. One end of the second valve body is provided with a second mounting port (unmarked), and the other end is provided with a second mounting hole (unmarked). The second rotating valve plate 422 and the second fixed valve plate are installed in the second valve body in sequence through the second mounting hole, thereby realizing a modular design using the second valve body.

[0218] In some embodiments, for the convenience of water circuit connection and user operation, the regeneration valve core further includes a second water distribution plate 424 and a second valve stem 425. The second water distribution plate is provided with a plurality of second through holes 4241. The second water distribution plate is disposed in the second mounting port. The second valve stem passes through the second mounting hole and is connected to the second rotating valve plate. The second fixed valve plate is disposed on the second water distribution plate and is located between the second water distribution plate and the second rotating valve plate. The second inlet and outlet are respectively connected to the connection channel through the corresponding second through holes.

[0219] Specifically, during assembly, the second valve stem 425, the second rotating valve plate 422, the second fixed valve plate, and the second water distribution plate 424 are sequentially installed into the second valve body through the second mounting port, and the second valve stem 425 extends from the second mounting hole to the outside of the second valve body.

[0220] The second fixed valve plate and the second rotating valve plate are made of wear-resistant materials (such as ceramic valve plates). By configuring the second water distribution plate on the outside of the second fixed valve plate, on the one hand, the second water inlet and outlet on the second fixed valve plate can be connected to the corresponding connecting channel through the corresponding second through hole. On the other hand, the second water distribution plate squeezes the second fixed valve plate from the outside, so that the second fixed valve plate and the second rotating valve plate are tightly attached together to ensure a sealed connection between the two.

[0221] One end of the second valve stem is sealed and inserted into the second valve body and connected to the second rotating valve plate, while the other end is exposed and equipped with a knob to facilitate the user to drive the second rotating valve plate to rotate via the knob.

[0222] In order to achieve a tight connection between the second fixed valve plate 421 and the second water distribution plate 424, a second inner sealing gasket 426 is provided on the inner side of the second water distribution plate. The second inner sealing gasket is used to seal the outer periphery of the second through hole and the corresponding second inlet / outlet. A second outer sealing gasket 427 is provided on the outer side of the second water distribution plate. The second outer sealing gasket is used to seal the outer periphery of the second through hole and the corresponding port of the connection channel located in the third installation space.

[0223] Specifically, the second inner sealing gasket is used to seal the connection between the second through hole and the second inlet / outlet. Similarly, the second outer sealing gasket is provided on the outside of the second water distribution plate to seal the connection between the second through hole and the third installation space.

[0224] In some embodiments, to facilitate the installation of the sealing gasket, a second mounting groove can be provided around the first through hole on the inner and outer surfaces of the second water distribution plate, with the second outer sealing gasket and the second inner sealing gasket located in the second mounting groove. Specifically, the structure of the second mounting groove matches the shape of the sealing gasket, and during assembly, the sealing gasket is secured in the second mounting groove for easy assembly.

[0225] In some embodiments, a second notch 4232 is provided on the edge of the second mounting port, and a first locking block 4241 is provided on the second water distribution plate, the first locking block being engaged in the second notch. A second locking block 4242 is provided on the second water distribution plate, and a third notch 4212 is provided on the second fixed valve plate, the second locking block being engaged in the third notch.

[0226] Specifically, during the assembly process, the second valve stem 425, the second rotating valve plate 422, the second fixed valve plate, and the second water distribution plate 424 are sequentially installed into the second valve body through the second mounting port. The second water distribution plate is positioned and does not rotate by the first locking block cooperating with the second notch. Similarly, the second locking block cooperates with the third notch to position the second fixed valve plate and prevent it from rotating.

[0227] In one embodiment, for ease of connection and assembly, the second water distribution plate is connected to the second valve body via a snap-fit ​​method. Specifically, a second latch (unmarked) is provided on the edge of the second mounting port, and a second claw (unmarked) is provided on the second water distribution plate, the second claw being engaged in the second latch.

[0228] In another embodiment, the second valve body includes a first sleeve segment (unmarked) and a second sleeve segment (unmarked) connected together. The diameter of the first sleeve segment is smaller than the diameter of the second sleeve segment. The port of the first sleeve segment forms the second mounting hole, and the port of the second sleeve segment forms the second mounting opening. The second sleeve segment is provided with the hollow hole. A first sealing ring (unmarked) is fitted on the second valve stem. The first sealing ring is sandwiched between the inner wall of the first sleeve segment and the second valve stem. A second sealing ring 4213 is fitted on the second sleeve segment. The second sealing ring is located between the hollow hole and the first sleeve segment.

[0229] Specifically, the first sealing ring ensures a water-tight connection between the second valve stem, which extends beyond the second valve body, and the second valve body. More importantly, because the second sleeve section has the perforated hole to meet the water inlet requirements, the second sealing ring ensures that after the second valve body is installed in the third mounting space, water flows into the water inlet through the perforated hole from inside the second sealing ring. This allows water to enter from one side of the second valve body through the water inlet, enabling the second rotating valve plate to meet different water inlet requirements at two different positions, thereby simplifying the overall structure of the valve plate and improving its reliability.

[0230] Example 4: Based on the above technical solution, optionally, such as... Figures 15-18 As shown, for the outer shell 210, since multiple connection channels 2104 need to be set inside, in order to simplify the processing difficulty, the outer shell 210 adopts a split design, specifically: the outer shell 210 includes a first shell 211, a second shell 212 and a third shell 41.

[0231] The first housing 211 has a first mounting groove at one end and a plurality of first pairs of interfaces 2111 at the other end. The first pairs of interfaces 2111 are respectively connected to the first mounting groove. The temperature control valve core 220 is disposed in the first mounting groove to form a temperature control valve.

[0232] A second mounting groove is provided at one end of the second housing 212, and a plurality of second pairs of interfaces 2121 are provided at the other end of the second housing 212. The second pairs of interfaces 2121 are respectively connected to the second mounting groove. The water circuit control valve core 230 is provided in the second mounting groove to form a water circuit control valve.

[0233] A third mounting groove is provided at one end of the third housing, and a plurality of connection ports are provided on the third housing. The connection ports are respectively connected to the third mounting groove. The regeneration valve core is disposed in the third mounting groove and is used to selectively connect to at least two corresponding connection ports. The regeneration valve core and the third housing form a regeneration valve.

[0234] The first housing is connected to the second housing, the first pair of interfaces is connected to the corresponding second pair of interfaces to form a connection channel, the water circuit control valve core is used to selectively connect the corresponding connection channel, and the third housing is connected between the first housing and the second housing.

[0235] Specifically, the first housing 211 is provided with a first mounting groove to form the first mounting space; similarly, the second housing 212 is provided with a second mounting groove to form the second mounting space; and the third housing is provided with a third mounting groove to form the third mounting space. The first housing 211 cooperates with the temperature control valve core 220 to form a temperature control valve, the second housing 212 cooperates with the water circuit control valve core 230 to form a water circuit control valve, and the third housing cooperates with the regeneration valve core to form a regeneration valve.

[0236] For the first housing 211 and the second housing, they are directly connected to form a connection channel 2104 inside. Taking the first housing 211 as an example, the first housing 211 is provided with a first pair of interfaces 2111, which are connected to the corresponding positions of the first mounting groove through a water flow path formed inside the first housing 211. When the first housing 211 and the second housing 212 are connected together, the correspondingly arranged first pair of interfaces 2111 and second pair of interfaces 2121 will be inserted together, thereby forming a plurality of connection channels 2104 between the first housing 211 and the second housing 212.

[0237] The third housing is connected between the first housing and the second housing to meet the requirements of overall installation.

[0238] The first, second, and third housings, designed as separate units, are connected in a splicing manner. The first and second housings are joined together by a butt joint, utilizing corresponding first and second pairs of interfaces 2111 and 2121 to establish a water circuit connection between them. This eliminates the need for additional water pipes for external water circuit connections. Furthermore, each housing's internal water circuit is designed according to the functional requirements of its respective valve core, simplifying the overall internal water circuit design and effectively improving water circuit expansion capabilities. Additionally, the third housing is installed between the first and second housings to achieve a unified design of the housing 100, facilitating later assembly.

[0239] In some embodiments of this application, in order to meet the requirements of sealing and docking, the first housing 211 is provided with a plurality of protruding first joints (unmarked), and the first pair of interfaces 2111 is provided on the first joints; the end of the second housing 212 is provided with a plurality of first docking grooves (unmarked), and the second pair of interfaces 2121 is provided in the first docking grooves; wherein, the first joints are inserted into the corresponding first docking grooves.

[0240] Specifically, when the first housing 211 and the second housing 212 are assembled, the first connector is inserted into the first mating groove, thereby enabling the corresponding first pair of interfaces 2111 and the second pair of interfaces 2121 to connect and communicate. The protruding first connector and the recessed first mating groove facilitate accurate docking of the first housing 211 and the second housing 212, and the insertion of the first connector into the first mating groove can further improve the sealing performance of the connection between the first pair of interfaces 2111 and the second pair of interfaces 2121.

[0241] Alternatively, a plurality of raised second mating grooves may be provided on the first housing 211, and a first pair of interfaces 2111 may be provided in the second mating grooves; a plurality of raised second connectors may be provided on the end of the second housing 212, and a second pair of interfaces 2121 may be provided on the second connectors; wherein the second connectors are inserted into the corresponding second mating grooves.

[0242] In some embodiments of this application, when a thermostatic valve core is used for the temperature control valve core 220, the first housing 211 on which the thermostatic valve core is installed is provided with an inlet one, an inlet two, and a mixing outlet in the first installation space. The inlet one and the inlet two are arranged on one side of the thermostatic valve core, and the mixing outlet is arranged at the end of the thermostatic valve core. The thermostatic valve core is used to adjust the inflow rate of the inlet one and the inlet two according to the outlet water temperature of the mixing outlet.

[0243] Correspondingly, in order to meet the requirements of hot and cold water inlet, the first housing 211 and the second housing 212 are respectively provided with water inlet interface 2101, and the first housing 211 or the second housing 212 is also provided with water outlet interface 2102.

[0244] The water flow input from the water inlet 2101 on the first housing 211 enters the first inlet through the corresponding connection channel 2104, the water flow input from the water inlet 2101 on the second housing 212 enters the second inlet through the corresponding connection channel 2104, and the water flow output from the mixing outlet is output from the water outlet 2102 through the corresponding connection channel 2104.

[0245] Specifically, the thermostatic valve core installed in the first housing 211 can automatically adjust the mixing ratio of hot and cold water to achieve constant temperature water output. Hot and cold water flow into the first installation space through the water inlet ports 2101 on the two housings respectively. The thermostatic valve core automatically adjusts the mixing ratio of hot and cold water to achieve constant temperature water output.

[0246] In another embodiment, in order to meet the requirements for installing the water treatment filter element 240, an external interface 2103 can be provided on the first housing 211 and / or the second housing 212. The external interface 2103 is used to install the water treatment filter element 240, and the external interface 2103 is connected between the first installation space and the second installation space through a corresponding connection channel 2104.

[0247] Specifically, one or more external interfaces 2103 can be configured according to the water treatment requirements. For example, external interfaces 2103 can be provided on the first housing 211 and the second housing 212 respectively, so that multiple water treatment filter elements 240 can be installed through the external interfaces 2103.

[0248] Specifically, the water output from the temperature control valve enters the water treatment filter element 240 via the external interface 2103, then flows into the water circuit control valve and is output. The external interface 2103 is connected in the flow path between the first housing 211 and the second housing 212. Water output from the mixing outlet on the first housing 211 enters the water treatment filter element 240 via the external interface 2103 for water treatment. The treated water is then transported to the second housing 212 via the external interface 2103 and finally output from the outlet interface 2102 to the water-using end of the external water network.

[0249] In another embodiment of this application, the third housing 41 is provided with a water inlet 401, a liquid outlet 402, a liquid suction port 403, a liquid return port 405, a waste discharge port 406, and a water replenishment port 407. A functional flow channel 404 is provided inside the third housing 41. The functional flow channel 404 has a converging section 4041, an expanding section 4042, and a diversion section 4043. The converging section 4041 and the expanding section 4042 are connected to form a negative pressure zone. The diversion section 4043 is connected to the negative pressure zone. The converging section 4041 is selectively connected to the water inlet 401. The expanding section 4042 is selectively connected to the liquid outlet 402. The diversion section 4043 is connected to the liquid suction port 403.

[0250] Specifically, during the regeneration process, the converging section 4041 is connected to the inlet port 401, and the expanding section 4042 is connected to the outlet port 402. Cold water introduced by the second inlet connector 200 is introduced into the functional flow channel 404 via the inlet port 401. The water flow is guided from the converging section 4041 to the expanding section 4042. Under the action of the converging section 4041, the flow velocity gradually increases, and the water enters the expanding section 4042 to form a negative pressure. Under the action of this negative pressure, the guiding section 4043 draws the salt solution from the salt tank 5 through the suction pipe. The salt solution is drawn into the expanding section 4042, mixed with the cold water, and then output from the outlet port 402 and enters the water treatment filter element through the inlet hole 242, thereby regenerating the regenerating resin within the water treatment filter element.

[0251] Cold water flows in the functional flow channel 404, and the negative pressure zone formed at the junction of the converging section 4041 and the expanding section 4042 generates negative pressure on the guiding section 4043, which is used to draw in the salt solution from the salt tank 5. In this way, there is no need to configure an additional power source to drive the flow of the salt solution in the salt tank 5, achieving a compact structural design and reducing manufacturing costs.

[0252] Preferably, the converging section 4041 is curved toward the expanding section 4042 to generate a certain swirling flow in the water, thereby increasing the water flow velocity entering the expanding section 4042. Furthermore, the liquid outlet direction of the converging section 4041 is toward the outlet of the expanding section 4042, which can more effectively create a stronger negative pressure at the junction of the converging section 4041 and the expanding section 4042, thereby increasing the suction force generated by the diversion section 4043.

[0253] In order to facilitate the discharge of waste liquid generated during the regeneration process, the regeneration valve 4 is also equipped with a return port 405 and a waste discharge port 406, with the return port 405 selectively connected to the waste discharge port 406.

[0254] The return port 405 is also connected to the outlet port 243.

[0255] Specifically, during the regeneration process, the converging section 4041 is connected to the inlet port 401, the expanding section 4042 is connected to the outlet port 402, and the return port 405 is connected to the waste discharge port 406. Thus, cold water enters the functional flow channel 404 and is drawn into the salt solution in the salt tank 5, then flows out from the outlet port 402 into the water treatment filter element. This regenerates the regenerating resin in the water treatment filter element 240, turning it into waste liquid. The waste liquid flows out from the outlet hole 243 and into the large return port 405, and finally flows out from the regeneration valve 4 through the waste discharge port 406. For convenient drainage, a wastewater pipe (not shown) is also installed on the waste discharge port 406.

[0256] In another embodiment, to facilitate the user in adding water to the brine tank 5, the regeneration valve 4 is also equipped with a water inlet 407, which is selectively connected to the water inlet 401; the water inlet 407 is used to add water to the brine tank 5.

[0257] Specifically, after the user replenishes the salt tank 5 with regenerated salt, water also needs to be added to the salt tank 5. At this time, the water inlet 407 in the regeneration valve 4 is connected to the water inlet 401, and cold water is introduced through the water inlet 401 and delivered to the salt tank 5 from the water inlet 407.

[0258] In some embodiments, an internal partition 411 is formed in the third housing 41 of the regeneration valve 4, which divides the interior of the third housing 41 into two mounting cavities. The partition 411 is grooved to form a functional flow channel 404. According to the flow path design requirements, the partition 411 is provided with multiple connection holes 410 to meet the requirements of the functional flow channel 404 being connected to the water flow path of the inlet port 401, the outlet port 402 and the suction port 403 respectively.

[0259] In addition, a plug 412 is provided on the third housing 41. The plug 412 can be installed on the third housing 41 and seal and cover the functional flow channel 404 on the partition 411 to form a closed water flow channel, thereby reducing the processing difficulty of the functional flow channel 404 in the third housing 41.

[0260] During assembly, one of the mounting cavities serves as a third mounting control for mounting the regeneration valve core 42, while the other mounting cavity mounts the plug 412.

[0261] The functional flow channel configured in the regeneration valve 4 can use the Venturi principle to draw in the brine in the salt tank through the water inlet 401 and send it into the water treatment filter element. This allows the regeneration valve 4 to draw in the brine in the salt tank while switching water paths, thus eliminating the need for additional power components for the salt tank and reducing manufacturing costs.

[0262] In another embodiment, external interfaces 2103 are respectively provided on the first housing and the second housing for mounting water treatment filter elements. The external interfaces are connected between the first mounting space and the second mounting space via corresponding connection channels. Each external interface has an inlet (unmarked) and an outlet (unmarked). The inlet of the water treatment filter element communicates with the inlet, and the outlet of the water treatment filter element communicates with the outlet.

[0263] The liquid outlet is connected to the liquid inlet through a corresponding connecting channel, and the liquid return port is connected to the liquid outlet through a corresponding connecting channel.

[0264] Additionally, a first insertion pipe 413 and a second insertion pipe 414 can be provided on the third housing. The opening of the first insertion pipe 413 forms the liquid outlet, and the opening of the second insertion pipe 414 forms the liquid return port. Correspondingly, the first housing and the second housing are respectively provided with an inlet channel 2112 and a return channel 2113. The two inlet channels 2112 are connected through the corresponding connecting channels, and the two return channels 2113 are connected through the corresponding connecting channels. The inlet channel 2112 is connected to the corresponding inlet hole, and the return channel 2113 is connected to the corresponding outlet hole. The first housing is provided with a first insertion port 2114, which is connected to the inlet channel 2112. The second housing is provided with a second insertion port 2122, which is connected to the inlet and return channels. The first insertion pipe 413 is inserted into the first insertion port 2114, and the second insertion pipe 414 is inserted into the second insertion port 2122.

[0265] Specifically, to facilitate the flow path connection between the third housing and the first and second housings, and to simplify the structural complexity of the internal flow channels while simultaneously meeting the requirement of synchronous regeneration of the water treatment filter elements 240 on both sides during the regeneration process, an inlet flow channel 2112 and a return flow channel 2113 are respectively configured in the third housing and the second housing. The inlet flow channel 2112 connects to the corresponding connecting channel 2104 to connect to the inlet port in the external interface 2103, and the return flow channel 2113 connects to the corresponding connecting channel 2104 to connect to the outlet port in the external interface 2103.

[0266] The first insertion tube 413 on the third housing is inserted into the first insertion interface 2114 to connect the liquid outlet to the water inlet of the water treatment filter element 240; similarly, the second insertion tube 414 is inserted into the second insertion interface to connect the liquid return port to the water outlet of the water treatment filter element 240.

[0267] In another embodiment, in order to improve the connection reliability between the third housing and the first housing and the second housing, the first housing is provided with a first mounting slot 2115, the second housing is provided with a second mounting slot 2123, and the two sides of the third housing are respectively provided with plug-in parts 415, wherein one plug-in part 415 is inserted into the first mounting slot 2115 and the other plug-in part 415 is inserted into the second mounting slot 2123.

[0268] Specifically, during the assembly of the housing 100, the first housing and the second housing are joined together, while the third housing is sandwiched between the first housing and the second housing. This achieves the connection of the water flow path, and the third housing is more firmly installed and fixed by the plug-in component 415 cooperating with the mounting slot, thereby improving the reliability of later use.

[0269] Example 5: Based on the above examples, such as Figures 21-22 As shown, the water treatment filter element 240 is installed on the external interface 2103. Since the water treatment filter element 240 typically has a limited service life and therefore needs to be replaced periodically, a rotatable connecting connector 213 is provided on the housing 210 for easy user disassembly and installation. The free end of the connecting connector 213 is provided with the external interface 2103; the water treatment filter element 240 is then mounted on the external interface 2103.

[0270] Specifically, the water treatment filter element 240 is mounted on a rotatable connecting joint 213 configured on the housing 210, and the housing 210, its internal connecting channel 2104, and valve core together form an integrated water circuit component. Since the connecting joint 213 can rotate relative to the housing 210, when the water treatment filter element 240 needs to be disassembled, the connecting joint 213 can be rotated to pull the water treatment filter element 240 outwards, facilitating user disassembly. Similarly, when assembling the water treatment filter element 240, the connecting joint 213 can be rotated to a suitable installation angle for easy and quick installation.

[0271] In some embodiments, since the water treatment filter element 240 is configured, it is usually necessary to protect it. Therefore, the water treatment device 200 is installed entirely in the housing 100. The housing 100 and the water treatment device 200 are assembled together to form a water treatment equipment. The water treatment equipment produces corresponding functions depending on the application scenario. For example, if the water treatment equipment is installed in the bathroom and used in conjunction with a water heater, it can be used as a shower machine; the water treatment equipment can also be installed in the kitchen and used in conjunction with a small water heater. The specific usage method is not limited here.

[0272] In some embodiments, the water treatment filter element 240 can be installed in various structural forms. For example, the water treatment filter element 240 is threaded onto the external interface 2103.

[0273] To better meet the requirements of quick assembly and disassembly, the water treatment filter element 240 is inserted into the external interface 2103.

[0274] Specifically, the water treatment filter element 240 is installed on the external interface 2103 using a plug-in method, so that the user can disassemble it simply by plugging and unplugging the water treatment filter element 240.

[0275] In one embodiment, to ensure reliable connection, the water treatment filter element 240 is provided with a mounting element 241, and the housing 100 is provided with a mounting base 110, which has a mounting groove 111, and the mounting element 241 is engaged in the mounting groove 111.

[0276] Specifically, when installing the water treatment filter element 240, the connecting connector 213 rotates outward to facilitate the user's insertion of the water treatment filter element 240 into the external interface 2103. The water treatment filter element 240 is installed into the housing 100 by rotating the connecting connector 213. After the water treatment filter element 240 is installed in place, the retaining element 241 is engaged in the retaining groove 111. The engaging element 241 and the retaining groove 111 cooperate to ensure that the water treatment filter element 240 is securely and reliably installed and fixed.

[0277] In another embodiment, in order to ensure that the water treatment filter element 240 and the connecting connector 213 can be reliably inserted together and to avoid water leakage due to improper assembly, the edge of the outer interface 2103 is also provided with a positioning opening 21031, and the mounting piece 241 is also located in the positioning opening 21031.

[0278] Specifically, the connector 213 has a positioning opening 21031 on the edge of the outer interface 2103. When installing the water treatment filter element 240, the user needs to move the mounting piece 241 into the positioning opening 21031 to achieve proper installation. If the water treatment filter element 240 is not inserted into the connector 213, the mounting piece 241 will be outside the positioning opening 21031. During the process of rotating the connector 213 to make the mounting piece 241 snap into the slot 111, because the mounting piece 241 is outside the positioning opening 21031 and not properly installed, the mounting piece 241 and the slot 111 will also be misaligned, making it impossible to install and fix the water treatment filter element 240.

[0279] The above structural design ensures that the water treatment filter element 240 and the connecting joint 213 are properly installed, thereby reducing the occurrence of water leakage due to improper installation and improving the user experience.

[0280] In another embodiment, to facilitate the installation of the connector 213, the housing 210 is provided with a connector 214, and the end of the connector 214 is provided with an installation socket 215, which is connected to the corresponding connection channel. The side wall of the connector 214 is provided with an installation hole (unmarked), and a detachable limiting member 216 is provided in the installation hole. The connector 213 is provided with a plug, and the outer periphery of the plug is provided with a limiting groove 2131, in which the limiting member 216 is engaged.

[0281] Specifically, the connector 213 is also installed on the housing 210 by insertion. The limiting member 216 and the limiting groove 2131 cooperate with each other to ensure that the connector 213 is reliably connected to the housing 210 without coming out of the mounting socket, and also to meet the requirement that the connector 213 rotates relative to the housing 210.

[0282] The limiting member 216 has a U-shaped structure, and the side wall of the connecting seat 214 is provided with two mounting holes. The two ends of the limiting member 216 are respectively inserted into the corresponding mounting holes, and the plug is located between the two ends of the limiting member 216. Specifically, the limiting member 216 spans both sides of the connecting joint 213, providing a more reliable limiting effect on the connecting joint 213.

[0283] In addition, the limiting member 216 is provided with a snap-fit ​​part (unmarked), and the connecting seat 214 is provided with a snap-fit ​​mating part, wherein the snap-fit ​​part is snapped onto the snap-fit ​​mating part. Specifically, after the limiting member 216 is installed in place, the snap-fit ​​part and the snap-fit ​​mating part are snapped together to ensure that the limiting member 216 is securely and reliably installed on the connecting seat 214.

[0284] In another embodiment, in order to limit the rotation angle of the connector 213, a protruding rotation limiting block 217 is provided in the mounting socket, and a limiting rib 2132 is provided on the outer periphery of the plug of the connector 213, with the rotation limiting block 217 located between the two ends of the limiting rib 2132.

[0285] Specifically, during the rotation process, the rotation limit block 217 is located between the two ends of the limit rib 2132. When the connecting joint 213 rotates outward to the position of the maximum rotation angle, the rotation limit block 217 will abut against the corresponding end of the limit rib 2132.
