In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0069] Example 1, as Figures 1-3 As shown, the present invention also provides a multifunctional valve, including: a thermostatic valve and a water circuit control valve.

[0070] The thermostatic valve includes a first valve body 211 and a thermostatic valve core 220. A first mounting groove is provided at one end of the first valve body, and a plurality of first pairs of interfaces are provided at the other end of the first valve body. The first pairs of interfaces are respectively connected to the first mounting groove, and the thermostatic valve core is disposed in the first mounting groove.

[0071] A water circuit control valve, comprising a second valve body 212 and an on / off valve core, wherein a second mounting groove is provided at one end of the second valve body and a plurality of second pairs of interfaces are provided at the other end of the second valve body, the second pairs of interfaces being respectively connected to the second mounting groove, and the on / off valve core being disposed in the second mounting groove;

[0072] The first valve body is connected to the second valve body, the first pair of interfaces is connected to the corresponding second pair of interfaces to form a connection channel, and the on / off valve core is used to selectively connect the corresponding connection channel.

[0073] Specifically, for the housing 210 of the multi-functional valve, since multiple connection channels 2104 need to be set inside, in order to simplify the processing difficulty, the housing 210 adopts a split design, specifically: the housing 210 includes a first valve body 211 and a second valve body 212.

[0074] The first valve body 211 has a first mounting groove at one end and a plurality of first pairs of interfaces 2111 at the other end, which are respectively connected to the first mounting groove. The thermostatic valve core 220 is disposed in the first mounting groove. The second valve body 212 has a second mounting groove at one end and a plurality of second pairs of interfaces 2121 at the other end, which are respectively connected to the second mounting groove. The on / off valve core 230 is disposed in the second mounting groove.

[0075] The first valve body 211 and the second valve body 212 are connected together. The first pair of interfaces 2111 and the corresponding second pair of interfaces 2121 are connected to form a connection channel. The on / off valve core 230 is used to selectively connect the corresponding connection channel 2104.

[0076] The first valve body 211 is provided with a first mounting groove to form the first mounting space, and similarly, the second valve body 212 is provided with a second mounting groove to form the second mounting space. The first valve body 211 and the thermostatic valve core 220 cooperate to form a thermostatic valve, while the second valve body 212 and the on / off valve core 230 cooperate to form a water circuit control valve.

[0077] For a single valve body, taking the first valve body 211 as an example, the first valve body 211 is provided with a first pair of interfaces 2111. The first pair of interfaces 2111 are connected to the corresponding positions of the first mounting groove through the water flow path formed inside the first valve body 211. When the first valve body 211 and the second valve body 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 number of connection channels 2104 between the first valve body 211 and the second valve body 212.

[0078] By adopting a split design, the first valve body 211 and the second valve body 212 are connected in a docking manner. The corresponding first pair of interfaces 2111 and the second pair of interfaces 2121 are used to connect and complete the water circuit connection between the first valve body 211 and the second valve body 212. On the one hand, it can realize that there is no need to add water pipes for external water circuit connection. On the other hand, the two valve bodies are designed with internal water circuits according to the functional requirements of their respective valve cores. This can simplify the overall internal water circuit design difficulty and effectively improve the water circuit expansion capability.

[0079] In some embodiments of this application, in order to meet the requirements of sealing and docking, the first valve body 211 is provided with a plurality of protruding first connectors (unmarked), and the first pair of interfaces 2111 is provided on the first connectors; the end of the second valve body 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 connector is inserted into the corresponding first docking groove.

[0080] Specifically, when assembling the first valve body 211 and the second valve body 212, 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 valve body 211 and the second valve body 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.

[0081] Alternatively, a plurality of raised second mating grooves may be provided on the first valve body 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 valve body 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.

[0082] In some embodiments of this application, when a thermostatic valve core 220 is used, the first valve body 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 of the inlet one and the inlet two according to the outlet water temperature of the mixing outlet.

[0083] Correspondingly, in order to meet the requirements of hot and cold water inlet, the first valve body 211 and the second valve body 212 are respectively provided with water inlet interface 2101, and the first valve body 211 or the second valve body 212 is also provided with water outlet interface 2102.

[0084] The water flow input from the inlet port 2101 on the first valve body 211 enters the first inlet through the corresponding connection channel 2104, the water flow input from the inlet port 2101 on the second valve body 212 enters the second inlet through the corresponding connection channel 2104, and the water flow output from the mixing outlet is output from the outlet port 2102 through the corresponding connection channel 2104.

[0085] Specifically, the thermostatic valve core installed in the first valve body 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 valve bodies respectively. The thermostatic valve core automatically adjusts the mixing ratio of hot and cold water to achieve constant temperature water output.

[0086] 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 valve body 211 and / or the second valve body 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.

[0087] 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 valve body 211 and the second valve body 212 respectively, so that multiple water treatment filter elements 240 can be installed through the external interfaces 2103.

[0088] The water output from the thermostatic valve enters the water treatment filter element 240 through the external interface 2103, then flows into the water control valve and is output. Specifically, the external interface 2103 is connected in the flow path between the first valve body 211 and the second valve body 212. The water output from the mixing outlet on the first valve body 211 enters the water treatment filter element 240 through the external interface 2103 for water treatment. The treated water is then transported to the second valve body 212 through the external interface 2103 and finally output from the outlet interface 2102 to the water-using end of the external water network.

[0089] In Example 2, the main function of the on / off 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 4-6 As shown, the on / off valve core 230 includes a fixed valve plate 231 and a rotating valve plate 232. The fixed valve plate 231 is provided with at least one inlet / outlet group, which includes two inlet / outlet ports 2311. The rotating valve plate 232 is provided with a communicating groove 2321 that cooperates with the inlet / outlet group.

[0090] The rotating valve plate 232 is attached to the fixed valve plate 231 and can rotate relative to the fixed valve plate 231. The connecting groove 2321 selectively connects the two inlet and outlet ports 2311 in the corresponding inlet and outlet group. The inlet and outlet ports 2311 are connected to the corresponding connecting channel 2104.

[0091] Specifically, in actual use, a corresponding number of 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 two inlet / outlet ports 2311 within the same inlet / outlet group is controlled by rotating valve plate 232. Each inlet / outlet port 2311 is connected to its corresponding connecting channel 2104.

[0092] When it is necessary to connect the two connecting channels 2104, rotate the valve plate 232 to connect the two inlet and outlet ports 2311 in the same outlet group through the connecting groove 2321, thereby connecting the two connecting channels 2104 to each other. At the same time, by controlling the overlap area between the connecting groove 2321 and the inlet and outlet ports 2311, the water flow rate can be further controlled.

[0093] When it is necessary to disconnect the two connecting channels 2104, rotate the valve plate 232 to make the connecting groove 2321 disconnect from the inlet and outlet 2311, thereby disconnecting the two connecting channels 2104.

[0094] In some embodiments, to facilitate the installation of the on / off valve core 230, the on / off valve core 230 further includes a valve housing 233, a fixed valve plate 231 is fixedly disposed in the valve housing 233, and a rotating valve plate 232 is rotatably disposed in the valve housing 233, the valve housing 233 being located in the second installation space.

[0095] Specifically, the fixed valve plate 231 and the rotating valve plate 232 are respectively installed in the valve housing 233, and then uniformly assembled into the second installation space through the valve housing 233, thereby realizing a modular design.

[0096] In another embodiment, in order to enable the valve housing 233 to be quickly and conveniently installed in the second installation space, the on / off 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 valve housing 233.

[0097] Specifically, during the actual assembly process, after the fixed valve plate 231 and the rotating valve plate 232 are installed into the valve body 233, the installation position of the valve body 233 needs to be accurately matched with the connection channel 2104 in the outer casing 210, since the fixed valve plate 231 needs to be accurately connected to the connection channel 2104 in the outer casing 210. Therefore, the valve body 233 is directly inserted into the second installation space using a push-fit method. After the 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 valve body 233, ultimately achieving a secure and reliable installation of the on / off valve core 230 onto the outer casing 210.

[0098] In some embodiments, in order to make the fixed valve plate 231 more securely installed and to facilitate the user to drive the rotating valve plate 232 to rotate, one end of the valve housing 233 is provided with an installation port (unmarked), and the other end is provided with an installation hole (unmarked); the on / off valve core 230 also includes a water distribution plate 234 and a valve stem 235. The water distribution plate 234 is provided with a plurality of through holes 2341. The water distribution plate 234 is disposed in the installation port. The valve stem 235 passes through the installation hole and connects to the rotating valve plate 232. The fixed valve plate 231 is disposed on the water distribution plate 234 and is located between the water distribution plate 234 and the rotating valve plate 232; wherein, the inlet and outlet ports 2311 are respectively connected to the corresponding through holes 2341 and the connecting channel 2104.

[0099] Specifically, the fixed valve plate 231 and the rotating valve plate 232 are made of wear-resistant materials (such as ceramic valve plates). By configuring a water distribution plate 234 on the outside of the fixed valve plate 231, on the one hand, the water distribution plate 234 can be used to connect the inlet and outlet ports 2311 on the fixed valve plate 231 to the corresponding connecting channels through the corresponding through holes 2341. On the other hand, the water distribution plate 234 squeezes the fixed valve plate 231 from the outside, so that the fixed valve plate 231 and the rotating valve plate 232 are tightly attached together to ensure a sealed connection between the two.

[0100] One end of the valve stem 235 is sealed and inserted into the valve housing 233 and connected to the rotating valve plate 232, while the other end is exposed and equipped with a knob to facilitate the user to drive the rotating valve plate 232 to rotate via the knob.

[0101] To achieve a sealed connection between the fixed valve plate 231 and the water distribution plate 234, an inner sealing gasket 236 is provided on the inner side of the water distribution plate 234. The inner sealing gasket 236 is used to seal the outer periphery of the through hole 2341 and the corresponding inlet / outlet 2311. Specifically, the inner sealing gasket 236 is provided between the fixed valve plate 231 and the water distribution plate 234 to seal the connection between the through hole 2341 and the inlet / outlet 2311. Similarly, an outer sealing gasket 237 is provided on the outer side of the water distribution plate 234 to seal the outer periphery of the through hole 2341 and the corresponding connection channel 2104 located in the second installation space.

[0102] In addition, to facilitate quick and easy installation of the inner sealing gasket 236 and the outer sealing gasket 237, mounting grooves (unmarked) are provided on the inner and outer surfaces of the water distribution plate 234 around the through hole 2341, and the outer sealing gasket 237 and the inner sealing gasket 236 are located in the mounting grooves. Specifically, the structure of the mounting groove matches the shape of the sealing gasket, and during assembly, the sealing gasket is snapped into the mounting groove.

[0103] In another embodiment, in order to position and install the fixed valve plate 231, a notch 2331 is provided on the edge of the mounting port, and a first positioning protrusion 2312 is provided on the fixed valve plate 231, which is inserted into the notch 2331.

[0104] Specifically, during the assembly of the on / off valve core 230, the rotating valve plate 232, the fixed valve plate 231, and the water distribution plate 234 are sequentially inserted into the valve body 233 through the mounting port. The first positioning protrusion 2312 of the fixed valve plate 231 will be engaged in the notch 2331, so that the fixed valve plate 231 is fixed relative to the valve body 233 and does not rotate.

[0105] The water distribution plate 234 is provided with a second positioning protrusion 2342, which is inserted into the notch 2331. Similarly, when assembling the water distribution plate 234, after the water distribution plate 234 is installed on the valve body 233, the second positioning protrusion 2342 will also be located in the notch 2331, so that the water distribution plate 234 is fixed relative to the valve body 233 and does not rotate.

[0106] In addition, to facilitate the installation of the water distribution plate 234 and the 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 inner sealing gasket 236 is placed between the water distribution plate 234 and the fixed valve plate 231, and then the tongue 2343 is inserted into the slot 2313, so as to pre-assemble the water distribution plate 234 and the fixed valve plate 231 together.

[0107] In one embodiment, the water distribution plate 234 is connected to the valve housing 233 by a snap-fit ​​method. Specifically, during assembly, the water distribution plate 234 is installed and fixed to the valve housing 233 by a snap-fit ​​method. For example, the edge of the mounting port is provided with a buckle, and the water distribution plate 234 is provided with a claw, which is engaged in the buckle.

[0108] In some other embodiments, after the valve housing 233 is installed into the outer casing 210, in order to prevent the valve housing 233 from rotating in the outer casing 210 and causing incorrect water circuit connection, a positioning groove 2344 is provided on the 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.

[0109] Specifically, after the valve body 233 is inserted into the second installation space, the positioning block will be engaged in the positioning groove 2344, thereby positioning the valve body 233. The cooperation between the positioning block and the positioning groove 2344 ensures that the through hole 2341 and the connecting channel 2104 are precisely aligned, and effectively prevents the valve body 233 from rotating, thus improving reliability.

[0110] 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 on / off valve core 230, the thermostatic valve core 220, the water treatment filter element 240, and the on / off valve core 230 before exiting through the outlet port 2102. To meet the on / off control requirements of the aforementioned water flow path, the fixed valve plate 231 in the on / off valve core 230 is equipped with three sets of outlet groups: a first inlet / outlet group, a second inlet / outlet group, and a third inlet / outlet group.

[0111] The first sub-inlet interface is selectively connected to the first inlet through the first inlet / outlet group; the second sub-inlet interface is selectively connected to the second inlet through the second 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 inlet / outlet group.

[0112] 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 fixed valve plate 231, and the flow of cold water is controlled by opening and closing the two inlet / outlet ports 2311 in the first inlet / outlet group. Similarly, the hot water flows to the second inlet through the second outlet group on the fixed valve plate 231, and the flow of hot water is controlled by opening and closing the two inlet / outlet ports 2311 in the second 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 fixed valve plate 231.

[0113] Among them, the 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.

[0114] Specifically, the inlet / outlet port 2311, which connects to the outlet port 2102, is designated as the outlet port. Due to the size limitation of the outer casing 210, the cross-sectional area of ​​the connecting groove 2321 is relatively small, while the cross-sectional area of ​​the water flow at the connection point between the outlet port 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 port along the direction of water flow, the water 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.

[0115] Preferably, such as Figure 6 As shown, the outer surface of the fixed valve plate 231 is provided with a water storage tank 2314 with the same shape as the corresponding through hole 2341, and the outlet water port passes through the water storage tank 2314. Specifically, the shape of the water storage tank 2314 can match the shape of the corresponding through hole 2341, on the one hand to ensure 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 inlet and outlet 2311 used to communicate with the outlet water port is the inlet water port, and the outlet water port is adjacent to the inlet water port. A slope 2315 is formed in the water storage tank 2314 extending inclined away from the inlet water port.

[0116] Specifically, the slope 2315 satisfies the requirement that the cross-sectional area of ​​the 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 through hole 2341.

[0117] Example 3, as Figures 7-10 As shown, the present invention also provides a water treatment module 200 for treating flowing water, and can also control the flow rate and temperature. The water treatment module 200 includes the aforementioned multi-functional valve and a water treatment filter element 240. The water treatment filter element 240 is used to treat the flowing water; wherein the first installation space and the second installation space are connected by a connecting channel 2104, the inlet port 2101, the outlet port 2102, and the external port 2103 are respectively connected to the corresponding connecting channel 2104, the on / off valve core 230 is used to selectively connect the corresponding connecting channel 2104, and the water treatment filter element 240 is connected to the external port 2103.

[0118] Specifically, for the outer casing 210, its water inlet 2101 and water outlet 2102 are respectively connected to the external water network. For example, the water inlet 2101 is connected to the water supply end of the external water network, while the water outlet 2102 is connected to the water consumption end of the external water network.

[0119] In the actual assembly process, the thermostatic valve core 220 is installed in the first installation space, and the on / off valve core 230 is installed in the second installation space. The two installation spaces are connected by a connecting channel 2104 provided inside the housing 210. Since the connecting channel 2104 is built into the housing 210 and the first and second installation spaces are pre-connected according to the design requirements, during assembly, only the thermostatic valve core 220 and the on / off valve core 230 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. In addition, when installing in a user's home, the inlet port 2101, outlet port 2102, and external port 2103 are also connected to their respective installation spaces through the internal connecting channel 2104. This allows for on-site assembly where only the water pipes of the external water supply pipe need to be connected to the inlet port 2101 and the outlet port 2102.

[0120] As for the water treatment filter cartridge 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 assembly at the user's home. The physical form of the water treatment filter cartridge 240 can be a conventional water filter cartridge, such as a water purifier cartridge, aromatherapy cartridge, or foam cartridge, to achieve water purification, aromatherapy, and foaming functions respectively, thus realizing a multi-functional experience. The specific physical form of the water treatment filter cartridge 240 will not be limited or described in detail here.

[0121] In some embodiments, the flow path of the water input through the water inlet 2101 can be varied.

[0122] For example, water entering through inlet 2101 flows sequentially through on / off valve core 230, thermostatic valve core 220, water treatment filter element 240, and on / off valve core 230 before exiting through outlet 2102. Specifically, water supplied by the external water supply network enters through inlet 2101, first flows through on / off valve core 230 to facilitate control of the water flow; then, the water flows into the thermostatic 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 on / off valve core 230 before being exited through outlet 2102 to the water user end of the water supply network.

[0123] Alternatively, the water entering through the inlet port 2101 is sequentially passed through the thermostatic valve core 220, the on / off valve core 230, the water treatment filter element 240, and the on / off valve core 233 before being output from the outlet port 2102.

[0124] Alternatively, the water entering through the inlet port 2101 flows sequentially through the thermostatic valve core 220, the water treatment filter core 240, and the on / off valve core 230 before being output from the outlet port 2102.

[0125] In one embodiment of this application, the connecting channel 2104 arranged in the housing 210 is built into the housing 210. Since the internal space of the housing 210 is limited and needs to meet the requirements of 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 of water flow connection, such as... Figure 10 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.

[0126] Specifically, such as Figure 9 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 each of the two main waterways 21041. 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.

[0127] 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 the 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.

[0128] In another embodiment of this application, the main function of the thermostatic valve core 220 is to regulate the water temperature. The thermostatic valve core is preferred. Correspondingly, there are two configurations for the water inlet interface 2101, namely the first sub-water inlet interface and the second sub-water inlet interface.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] Example 4: Based on the above examples, such as Figures 11-13 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 user convenience in disassembling and installing the filter element. 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.

[0133] 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.

[0134] In some embodiments, since the water treatment filter element 240 is configured, it is usually necessary to protect it. For this reason, the water treatment module 200 is installed entirely in the housing 100. The housing 100 and the water treatment module 200 are assembled together to form a water treatment device. The water treatment device produces corresponding functions depending on the application scenario. For example, if the water treatment device is installed in the bathroom and used in conjunction with a water heater, it can be used as a shower machine; the water treatment device can also be installed in the kitchen and used in conjunction with a small water heater. The specific usage method is not limited here.

[0135] 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.

[0136] To better meet the requirements of quick assembly and disassembly, the water treatment filter element 240 is inserted into the external interface 2103.

[0137] Specifically, the water treatment filter element 240 is installed on the external interface 2103 using an insert method, so that the user can disassemble it simply by inserting and unplugging the water treatment filter element 240.

[0138] 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.

[0139] 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 rotated through the connecting connector 213 to be installed into the housing 100. 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] In addition, the limiting member 216 is provided with a snap-fit ​​part (not marked), 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.

[0147] 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.

[0148] 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.

[0149] Example 5, such as Figure 14-18 As shown, the present invention also provides a wall-mounted bathing device, which includes:

[0150] 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.

[0151] The multi-functional valve has an inlet port 2101, an outlet port 2102, and an external port 2103; the multi-functional valve is composed of a housing 210 and a thermostatic valve core 220 and an on / off valve core 230 disposed on the housing 210.

[0152] Water treatment filter element 240 is used to treat the water flowing in from the inlet pipe and output it from the outlet pipe.

[0153] The multi-functional valve and the water treatment filter element 240 are both housed inside the housing 100. The valve module is mounted on the first mounting base, and the water treatment filter element 240 is mounted on the second mounting base. The inlet pipe is connected to the inlet interface 2101, the outlet pipe is connected to the outlet interface 2102, and the water treatment filter element 240 is connected to the outer interface 2103. The housing 100 is used to hang the inlet pipe and / or the outlet pipe.

[0154] Specifically, in order to meet the requirements of bathroom installation, a wall-mounted housing 100 is adopted, and the housing 100 is suspended on the bathroom wall through the water inlet pipe and / or the water outlet pipe, while the multi-functional valve and water treatment filter 240 are centrally installed in the housing 100.

[0155] During installation in a user's home, the inlet pipe 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 is installed on the water supply outlet. Similarly, the outlet pipe is connected to the water pipe of the user's home water terminal.

[0156] The following description uses the inlet pipe housing 100 as an example.

[0157] The water inlet pipe 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, and the multi-functional valve and water treatment filter 240 in the housing 100 are fixedly installed in the housing 100 through the corresponding mounting brackets.

[0158] The housing 100 is mounted on the wall via the inlet or outlet pipe to meet the requirements for wall installation. Meanwhile, the multi-functional valve and water treatment filter 240 are centrally installed in the housing 100 to achieve a compact design and meet the requirements for unified and rapid on-site installation.

[0159] 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 multi-functional valve 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 multi-functional valve in the housing 100 allows for convenient wall mounting at a height suitable for user operation, thus utilizing the existing space where a mixing valve is installed.

[0160] In one embodiment of this application, the water inlet pipe passes through the back plate of the housing 100 and extends to the outside of the housing 100.

[0161] Specifically, the water inlet pipe 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 is arranged horizontally, which is more conducive to supporting the housing 100 and the multi-functional valve and water treatment filter 240 inside the housing 100. Furthermore, since the water entering the multi-functional valve is generally divided into cold water and hot water, the water inlet pipes can be arranged on both sides of the housing 100, with one water inlet pipe for transporting cold water and the other for transporting hot water.

[0162] In one embodiment, to facilitate on-site installation by operators, the water inlet pipe includes a first pipe body 1011 and a second pipe body 1012. The first pipe body 1011 is provided with an external threaded portion 1013. The axis of the external threaded 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 threaded portion 1013 is located outside the housing 100. The second pipe body 1012 is connected to the water inlet interface 2101.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] In addition, to facilitate the operator's operation of the locking screw 1014, an operating hole 130 can be provided on the housing 100, which is arranged opposite to the locking screw 1014. Specifically, during actual installation, after the positions of the first tube 1011 and the second tube 1012 are adjusted, 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 in the housing 100, the operator can insert a screwdriver into the operating hole 130 to tighten the locking screw 1014.

[0170] Based on the above technical solutions, such as Figure 16-17As 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.

[0171] 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, and the other end of the water treatment filter element 240 can also be supported by the support part 120.

[0172] 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.

[0173] 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.

[0174] 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.

[0175] 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.

[0176] 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.

[0177] 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.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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 in its length direction. The recessed part formed by the second mounting seat can further position and support the middle area of ​​the water treatment filter element 240, which is more conducive to improving the installation reliability.
