Description

Affected by the water quality of the municipal water supply network, more and more users are additionally equipped with filtering equipment before the water terminal (such as faucet or shower) to filter the water through the filtering equipment.

[0003] When users use water heaters at home, they are usually connected to the water terminal through a mixing valve. At the same time, in order to realize the on-off switching of the water circuit, an on-off valve is usually provided. The on-off valve and the mixing valve are generally connected through a water pipe, or the on-off valve is installed at the water outlet of the mixing valve. At the same time, as people's requirements for water quality increase, soft water modules will be added to the water circuit. For this purpose, a regeneration valve needs to be configured for the soft water module, and the regeneration valve also needs to be connected through an external pipeline.

[0095] Embodiment 1, as Figure 1-Figure 3 As shown, the water treatment device of this embodiment is used to soften the water flowing through, and at the same time, it can also realize the control of the water flow size and on-off of the water temperature regulation. The water treatment device 200 includes:

[0096] The housing 210 is provided with a water inlet interface 2101, a water outlet interface 2102, an external interface 2103, the liquid suction port and the waste discharge port. The housing 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 housing 210 is also provided with a plurality of connecting channels 2104;

[0097] A temperature control valve core 220, which is disposed in the first installation space and is used to control the outlet water temperature of the water treatment device 200;

[0098] A waterway control valve core 230, which is disposed in the second installation space;

[0099] A regeneration valve core, the regeneration valve core is arranged in the third installation space;

[0100] A water treatment filter element 240, the water treatment filter element 240 is used to treat the water flowing through;

[0101] A salt box, wherein a liquid suction tube is arranged in the salt box;

[0102] Wherein, the first installation space, the second installation space and the third installation space are respectively connected to each other through the connecting channel, and the water inlet interface, the water outlet interface, the external interface and the liquid suction port are respectively connected to the corresponding connecting channels;

[0103] The temperature control valve core controls the outlet water temperature of the water treatment device, the water circuit control valve core is used to control the on-off of the connecting channel between the water inlet interface, the water outlet interface and the external interface, the regeneration valve core is used to control the on-off of the connecting channel between the water inlet interface, the external interface, the liquid suction port and the waste discharge port, and the liquid suction tube is connected to the liquid suction port.

[0104] Specifically, for the housing 210, the water inlet interface 2101 and the water outlet interface 2102 are respectively connected to the external water network, for example, the water inlet interface 2101 is connected to the water supply end of the external water network, and the water outlet interface 2102 is connected to the water use end of the external water network.

[0105] During 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, and the three installation spaces are connected via a connecting channel 2104 provided inside the outer shell 210. Since the connecting channel 2104 is built into the inner shell 210 and the first installation space, the second installation space and the third installation space are pre-connected according to 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 the corresponding installation spaces to complete the assembly, thereby reducing the number of connections made one by one through water pipes during the valve core assembly process to simplify the assembly process.

[0106] In addition, when installing at the user's home, the water inlet interface 2101, the water outlet interface 2102, and the external interface 2103 are also connected to the corresponding installation space through the internal connecting channel 2104, so that when assembling on site, it is only necessary to connect the water pipes of the external water supply pipe to the water inlet interface 2101 and the water outlet interface 2102 accordingly.

[0107] As for the water treatment filter element 240, it can be connected to the external interface 2103 at the factory stage, and can also be connected to the external interface 2103 when assembled at the user's home.

[0108] The water treatment filter element 240 can achieve water softening treatment, and the specific performance entity of the water treatment filter element 240 is not limited or elaborated herein.

[0109] In some embodiments, the water flow inputted by the water inlet interface 2101 may have a variety of flow paths depending on the status of different valve cores.

[0110] The water path control valve core 230 can control the on-off of the water path entering the temperature control valve core, and can further control the water flow rate as needed. The specific flow path is as follows.

[0111] For example, the water entering the water inlet interface 2101 is sequentially output from the water outlet interface 2102 through the water circuit control valve core 230, the temperature control valve core 220, the water treatment filter core 240, and the water circuit control valve core 230. Specifically, after the water supplied by the external water supply network enters the water inlet interface 2101, it first flows through the water circuit control valve core 230 to conveniently control the on-off of the water circuit through the water circuit control valve core 230; then, the water flows into the temperature control valve to adjust the temperature; the water with the adjusted temperature enters the water treatment filter core 240 for water quality treatment, and finally passes through the water circuit control valve core 230 and is output from the water outlet interface 2102 to the water-using end of the water supply network.

[0112] Alternatively, the water flow entering the water inlet interface 2101 is sequentially output from the water outlet interface 2102 through the temperature control valve core 220, the water channel control valve core 230, the water treatment filter element 240, and the water channel control valve core 230;

[0113] Alternatively, the water flow entering the water inlet interface 2101 is output from the water outlet interface 2102 through the temperature control valve core 220, the water treatment filter core 240, and the water channel control valve core 230 in sequence.

[0114] As for the regeneration valve core, it is used to control the on-off of the flow path between the water treatment filter element and the salt box. The specific flow path is as follows.

[0115] When the regeneration valve core is in the conducting state, the water flow entering the water inlet interface passes through the regeneration valve core, the water treatment filter element, and the regeneration valve core in sequence and is output from the waste outlet. Specifically, after the water supplied by the external water supply network enters the water inlet interface 2101, it first flows through the regeneration valve core to drive the salt solution in the salt box to follow and flow out and enter the water treatment filter element, and 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.

[0116] In some embodiments, the housing is further provided with a water replenishment port, the water replenishment port is communicated with the salt tank, and the regeneration valve core is also used to control the on-off of the connection channel between the water inlet interface and the water replenishment port.

[0117] Specifically, for the regeneration valve core, in addition to the function of controlling the on-off of the flow path between the water treatment filter element and the salt box, it also has the function of controlling the water replenishment to the salt box. In the water replenishment state, the specific flow path is as follows.

[0118] When the regeneration valve core is in the conducting state 2, the water flow entering the water inlet interface flows into the salt box through the regeneration valve core in sequence.

[0119] In one embodiment of the present application, Figure 4-Figure 6As shown, for the connection channel 2104 arranged in the housing 210, it is built in the housing 210. Since the internal space of the housing 210 is limited and the requirements for connecting different water flow paths need to be met, in order to reduce the processing difficulty of forming the connection channel 2104 in the housing 210, for the connection channel 2104, according to different positions of the connection channel 2104 inside the housing 210 and the requirements for water path connection, as shown in FIG. Figure 6 As shown, part of the connecting channel 2104 is a complete water channel directly formed in the outer shell 210, while for the remaining connecting channel 2104, it is necessary to realize the bending flow of water. For the connecting channel 2104 corresponding to this situation, it is formed in the outer shell 210 by a split connection method.

[0120] Specifically, Figure 5 As shown, the connecting channel 2104 includes two main water channels 21041 and a secondary water channel 21042. The two main water channels 21041 are arranged in parallel and staggered. The secondary water channel 21042 is staggered with the two main water channels 21041 and respectively connects the two main water channels 21041. One end of the secondary water channel 21042 is located on the outer surface of the housing 210 and is provided with a plug 21043. The two main water channels 21041 are not arranged in the same line, such as being staggered up and down or left and right, and the secondary water channel 21042 is connected to the two main water channels 21041 to realize the bending water transportation of the connecting channel 2104.

[0121] Thus, in the actual processing, the shell 210 is usually processed by conventional processing methods such as injection molding. For the integral connecting channel 2104, the entirety is built into the shell 210, and for the split-design connecting channel 2104, the connecting channel 2104 is formed by the cooperation of the secondary water channel 21042 and the two main water channels 21041, and one end of the secondary water channel 21042 is located on the surface of the shell 210 to facilitate processing and molding, and at the same time, the end of the secondary water channel 21042 is further sealed by the plug 21043.

[0122] In another embodiment of the present application, the temperature control valve core 220 is mainly used to adjust the water temperature, and preferably a thermostatic valve core is used.

[0143] In another embodiment, in order to meet the requirements for installing the water treatment filter element 240, an external interface 2103 can be set on the first shell 211 and / or the second shell 212, and the external interface 2103 is used to install the water treatment filter element 240. The external interface 2103 is connected between the first installation space and the second installation space through the corresponding connecting channel 2104.

[0144] Specifically, one or more external interfaces 2103 may be configured according to the requirements of water treatment. For example, external interfaces 2103 may be provided on the first shell 211 and the second shell 212 respectively, so that multiple water treatment filter cartridges 240 can be installed through the external interfaces 2103 .

[0145] The water outputted by the temperature control valve enters the water treatment filter element 240 through the external interface 2103, then flows into the water circuit control valve and is outputted. Specifically, the external interface 2103 is connected to the flow path between the first shell 211 and the second shell 212. The water outputted from the mixed water outlet on the first shell 211 enters the water treatment filter element 240 through the external interface 2103 for water quality treatment. The treated water is then transported to the second shell 212 through the external interface 2103 and finally outputted from the water outlet interface 2102 to the water use end of the external water pipe network.

[0146] In another embodiment of the present application, for the third shell, a water inlet interface 401, a liquid outlet 402, a liquid suction port 403, a liquid return port 405, a waste outlet 406, and a water replenishment port 407 are provided on the third shell 41, and a functional flow channel 404 is provided in the third shell 41, and the functional flow channel 404 has a tapered section 4041, an expansion section 4042 and a drainage section 4043, the tapered section 4041 is connected to the expansion section 4042 and forms a negative pressure zone, the drainage section 4043 is connected to the negative pressure zone, the tapered section 4041 is selectively connected to the water inlet interface 401, the expansion section 4042 is selectively connected to the liquid outlet 402, and the drainage section 4043 is connected to the liquid suction port 403.

[0147] Specifically, during the regeneration process, the tapered section 4041 is connected to the water inlet interface 401, and the expanded section 4042 is connected to the liquid outlet 402. The cold water introduced by the second water inlet joint 200 is introduced into the functional flow channel 404 via the water inlet interface 401, and the water flow is guided to flow to the expanded section 4042 via the tapered section 4041. Under the action of the tapered section 4041, the flow rate of the water flow gradually increases, and the water flow enters the expanded section 4042 to form a negative pressure. Under the action of the negative pressure, the drainage section 4043 sucks the salt solution in the salt box 5 through the liquid suction pipe. The salt solution is sucked into the expanded section 4042 and mixed with the cold water, then output from the liquid outlet 402 and enter the water treatment filter element via the water inlet hole 242, thereby regenerating the regeneration resin in the water treatment filter element.

[0148] Cold water flows in the functional flow channel 404, and the negative pressure area formed by the cooperation between the tapered section 4041 and the expanded section 4042 is used to generate negative pressure on the drainage section 4043, and the negative pressure is used to suck the saline solution in the salt box 5. In this way, there is no need to configure an additional power source to drive the flow of the saline solution in the salt box 5, achieving a compact structure design and being more conducive to reducing manufacturing costs.

[0149] Preferably, the tapered section 4041 is bent as a whole toward the expansion section 4042 so that the water flow produces a certain swirl, thereby increasing the water flow velocity entering the expansion section 4042, and the liquid outlet direction of the tapered section 4041 is toward the outlet of the expansion section 4042, which can more effectively form a stronger negative pressure at the joint of the tapered section 4041 and the expansion section 4042, thereby increasing the suction generated by the drainage section 4043.

[0154] Specifically, after the user replenishes the regeneration salt into the salt box 5 , water needs to be injected into the salt box 5 . At this time, the water replenishment port 407 in the regeneration valve 4 is connected to the water inlet port 401 , and cold water is introduced through the water inlet port 401 and transported to the salt box 5 from the water replenishment port 407 .

[0155] In some embodiments, an internal partition 411 is formed in the third shell 41 of the regeneration valve 4, and the interior of the third shell 41 is divided into two installation cavities by the partition 411. The functional flow channel 404 is formed by grooving on the partition 411. According to the flow path design requirements, the partition 411 is provided with multiple connecting holes 410 to meet the requirements of connecting the functional flow channel 404 to the water inlet interface 401, the liquid outlet 402 and the liquid suction port 403 respectively.

[0157] During assembly, one of the installation cavities is used as a third installation control for installing the regeneration valve core 42 , and the other installation cavity is used for installing the plug 412 .

[0158] The functional flow channel configured in the regeneration valve 4 can utilize the Venturi principle to introduce water through the water inlet interface 401 to suck the brine in the salt box and send it into the water treatment filter element, so that the regeneration valve 4 can absorb the brine in the salt box while switching the water path, and there is no need to equip the salt box with additional power components, which is more conducive to reducing manufacturing costs.

[0186] Specifically, after the first valve body 233 is inserted into the second installation space, the positioning block will be stuck in the positioning groove 2344, thereby positioning the first valve body 233. Under the mutual cooperation of the positioning block and the positioning groove 2344, on the one hand, the first through hole 2341 and the connecting channel 2104 can be accurately docked together, and on the other hand, the first valve body 233 can be effectively prevented from rotating, so as to improve the reliability of use.

[0187] In some embodiments, the flow path of the water flow is described by taking the water flow entering from the two water inlet interfaces 2101 and then passing through the water path control valve core 230, the temperature control valve core 220, the water treatment filter core 240, and the water path control valve core 230 and outputting from the water outlet interface 2102 as an example. In order to meet the on-off control requirements of the above-mentioned water flow path, the first fixed valve plate 231 in the water path control valve core 230 is provided with three groups of water outlet population groups, namely, the first sub-inlet and outlet group, the second sub-inlet and outlet group, and the third sub-inlet and outlet group.

[0188] The first sub-water inlet interface and the inlet one are selectively connected through the first sub-inlet and outlet group, the second sub-water inlet interface and the inlet two are selectively connected through the second sub-inlet and outlet group, the mixed water outlet is connected to the external interface 2103 through the connecting channel 2104, and the external interface 2103 and the water outlet interface 2102 are selectively connected through the third sub-inlet and outlet group.

[0189] Specifically, taking the introduction of cold water through the first sub-inlet interface and the introduction of hot water through the second sub-inlet interface as an example, the cold water flows to the inlet 1 through the first water outlet group on the first fixed valve plate 231, and the on-off of the cold water is controlled by controlling the on-off of the two first water inlets 2311 in the first sub-inlet and outlet group. Similarly, the hot water flows to the inlet 2 through the second water outlet group on the first fixed valve plate 231, and the on-off of the hot water is controlled by controlling the on-off of the two first water inlets 2311 in the second sub-inlet and outlet group. The water flow treated by the water treatment filter 240 flows to the water outlet interface 2102 through the third water outlet group on the first fixed valve plate 231.

[0190] The first water inlet and outlet 2311 connected to the water outlet interface 2102 through the connecting channel 2104 is the water outlet, and the water flow cross-sectional area of ​​the water outlet gradually increases along with the flow direction of the water flow.

[0191] Specifically, the first water inlet and outlet 2311 connected to the water outlet interface 2102 is set as the water outlet. Due to the size limitation of the housing 210, the cross-sectional size of the first connecting groove 2321 is relatively small, while the cross-sectional size of the water flow at the water outlet and the connecting and disconnecting connection part is relatively large. During the water flow output process, it will diffuse outward and easily cause turbulence due to the sudden change of the cross-sectional area. By gradually increasing the cross-sectional area of ​​the water flow at the water outlet along the flow direction of the water flow, the water flow turbulence caused by the diffusion of the water flow can be reduced, and the formation of cavities during the flow of the water flow can be reduced, thereby reducing the occurrence of water flow noise, so as to improve the user experience.

[0192] Preferably, if Fig. 9As shown, the outer surface of the first fixed valve plate 231 is provided with a water tank 2314 having the same shape as the corresponding first through hole 2341, and the output water port penetrates the water tank 2314. Specifically, the shape of the water tank 2314 can match the shape of the corresponding first through hole 2341, on the one hand to ensure the reliability of the water connection to reduce the occurrence of water leakage, on the other hand the water tank 2314 can further play the role of buffering the water flow. The first water inlet and outlet 2311 used to communicate with the output water port is the input water port, the output water port is adjacent to the input water port, and a slope 2315 extending obliquely away from the input water port is formed in the water tank 2314. Specifically, the slope 2315, on the one hand, satisfies the requirement that the water flow cross-sectional area of ​​the output water port gradually increases with the flow direction of the water flow, and on the other hand, can also guide the water flow to be better distributed to the corresponding first through hole 2341.

[0195] Specifically, in actual use, a corresponding number of second inlet and outlet groups are configured according to the flow path on-off requirements of the regeneration valve core 42, and the on-off control of the two second inlet and outlet ports in the same second inlet and outlet group is controlled by the second rotating valve plate. The second inlet and outlet ports are respectively connected to the corresponding connection channels 2104 formed inside the housing.

[0196] In addition, for the water flow entering the third installation space, it enters the interior of the regeneration valve core through the water inlet gap, and the second connecting groove selectively connects two of the second water inlets and outlets in the corresponding second inlet and outlet group, so that the water entering from the water inlet gap flows through the two connected second water inlets and outlets, and finally flows through the corresponding connecting channel 2104 in the outer shell according to the set flow path.

[0197] The following is an explanation based on the different states of the regeneration valve core in conjunction with the accompanying drawings. Figure 12-14 As shown, the solid line represents the second fixed valve disc 421 , and the dotted line represents the second rotating valve disc 422 .

[0198] like Fig.12 As shown, the regeneration valve core is in a closed state, the water inlet gap is shielded by the second fixed valve plate, and water cannot enter the second water inlet and outlet 4211 provided on the second fixed valve plate 421 .

[0199] like Fig.13 As shown, the regeneration valve core is in the regeneration state, and the second rotating valve plate 422 rotates by a set angle so that the water inlet gap is aligned with Fig.13 The second water inlet and outlet corresponding to the left side of the middle is connected to the water treatment filter element, and at the same time, the corresponding water inlet and outlet are connected through the second connecting channel, so that the water input from the water inlet gap is finally output through the second water inlet and outlet connected to the water treatment filter element. At the same time, Fig.13 The two second water inlet and outlet outputs on the middle right side are used to connect the water outlet hole of the water treatment filter element and the waste outlet through the corresponding second connecting grooves.

[0202] Specifically, in order to conveniently install the regeneration valve core in the third installation space, the second fixed valve disc 421 and the second rotating valve disc 422 are installed in the second valve body. In this way, the regeneration valve core can be installed in the third installation space through the second valve body.

[0205] Specifically, during assembly, the second valve stem 425, the second rotating valve plate 422, the second fixed valve plate and the second water diversion 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.

[0206] 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 dividing plate on the outer side 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 holes by using the second water dividing plate, and on the other hand, the second water dividing 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 to each other to ensure a sealed connection between the two.

[0207] One end of the second valve stem is sealed and inserted into the second valve body and connected to the second rotating valve plate, and the other end is exposed to the outside and is provided with a knob, so that the user can drive the second rotating valve plate to rotate by turning the knob.

[0208] In order to achieve the sealing of the connection between the second fixed valve plate 421 and the second water diversion plate 424, a second inner sealing gasket 426 is provided on the inner side of the second water diversion plate, and the second inner sealing gasket is used to seal the second through hole and the outer circumference of the corresponding second water inlet and outlet; a second outer sealing gasket 427 is provided on the outer side of the second water diversion plate, and the second outer sealing gasket is used to seal the second through hole and the outer circumference of the port of the corresponding connecting channel located in the third installation space.

[0209] Specifically, the second inner sealing gasket is used to seal the connection between the second through hole and the second water inlet and outlet. Similarly, the second outer sealing gasket is arranged on the outer side of the second water distribution plate, and the second outer sealing gasket is used to seal the connection formed by the second through hole and the third installation space.

[0210] In some embodiments, in order to facilitate the installation of the sealing gasket, a second installation groove may be provided on the inner and outer surfaces of the second water diversion plate around the first through hole, and the second outer sealing gasket and the second inner sealing gasket are located in the second installation groove. Specifically, the structure of the second installation groove matches the structural shape of the sealing gasket, and during assembly, the sealing gasket is clamped in the second installation groove to facilitate assembly.

[0211] In some embodiments, the edge of the second installation opening is provided with a second notch 4232, the second water distribution plate is provided with a first clamping block 4241, and the first clamping block is clamped in the second notch. The second water distribution plate is provided with a second clamping block 4242, the second fixed valve plate is provided with a third notch 4212, and the second clamping block is clamped in the third notch.

More importantly, since the second pipe sleeve section is provided with the hollow hole to meet the water inlet requirement of the water inlet gap, the second sealing ring is provided on the second pipe sleeve section, so that after the second valve body is installed in the third installation space, it is ensured that water flows into the water inlet gap through the hollow hole on the inner side of the second sealing ring. In this way, water can be fed into the water inlet gap from one side of the second valve body, so that the second rotating valve plate can meet different water inlet requirements at two different positions, thereby simplifying the overall structure of the valve plate and improving the reliability of use.

[0216] Embodiment 5: Based on the above embodiment, Figure 21-22 As shown, for the water treatment filter element 240, it is installed on the external interface 2103, and the water treatment filter element 240 usually has a certain service life, so it needs to be replaced regularly. In order to facilitate the user to disassemble and install the filter element. A rotatable connecting joint 213 is configured on the housing 210, and the free end of the connecting joint 213 is provided with an external interface 2103; the water treatment filter element 240 is arranged on the external interface 2103.

[0217] Specifically, the water treatment filter element 240 is installed on the rotatable connection joint 213 configured on the housing 210, and the housing 210 and the connection channel 2104 and the valve core configured therein together constitute an integrated water channel component. Since the connection joint 213 can be rotated relative to the housing 210, when the water treatment filter element 240 needs to be disassembled, the connection joint 213 can be rotated so that the water treatment filter element 240 can be pulled out to the outside, thereby facilitating the user to disassemble; similarly, when assembling the water treatment filter element 240, the connection joint 213 can be rotated to a suitable installation angle to easily and quickly install the water treatment filter element 240.

[0218] In some embodiments, due to the configuration of the water treatment filter element 240, it is usually necessary to protect the water treatment filter element 240. For this reason, the water treatment device 200 is installed as a whole in the housing 100. The housing 100 and the water treatment device 200 are assembled together to form a water treatment device. The water treatment device has corresponding functions when applied to different usage scenarios. For example, the water treatment device is installed in the shower room and used in conjunction with the water heater, and can be used as a shower machine; and the water treatment device can also be installed in the kitchen and used in conjunction with a small kitchen treasure. There is no restriction on its specific usage method.

[0219] In some embodiments, there may be a variety of structural forms for the installation of the water treatment filter element 240 . For example, the water treatment filter element 240 is threadedly connected to the external interface 2103 .

[0220] In order to better meet the requirements of rapid disassembly and assembly, the water treatment filter element 240 is inserted into the external interface 2103 .

[0221] Specifically, the water treatment filter element 240 is installed on the external interface 2103 by plugging and unplugging. In this way, the user only needs to plug and unplug the water treatment filter element 240 to realize disassembly.

[0222] In one embodiment, in order to ensure connection reliability, a clamping member 241 is provided on the water treatment filter element 240 , a clamping seat 110 is provided in the housing 100 , the clamping seat 110 is provided with a clamping slot 111 , and the clamping member 241 is clamped in the clamping slot 111 .

[0223] Specifically, when installing the water treatment filter element 240, the connection joint 213 rotates outward to facilitate the user to insert the water treatment filter element 240 into the external interface 2103. The water treatment filter element 240 is connected to the connection joint 213 and rotates to be installed in the housing 100. After the water treatment filter element 240 is installed in place, the clamping member 241 is clamped in the clamping groove 111. The clamping member 241 cooperates with the clamping groove 111 to ensure that the water treatment filter element 240 can be firmly and reliably installed and fixed.

[0224] In another embodiment, in order to ensure that the water treatment filter element 240 and the connecting joint 213 can be reliably inserted together to avoid water leakage due to improper assembly, a positioning opening 21031 is also provided at the edge of the external interface 2103, and the clamping part 241 is also located in the positioning opening 21031.

[0225] Specifically, the connection joint 213 is provided with a positioning opening 21031 at the edge of the external interface 2103. When the user installs the water treatment filter element 240, the user needs to move the clamping member 241 into the positioning opening 21031 to achieve the installation in place. If the water treatment filter element 240 is inserted and installed in place on the connection joint 213, at this time, the clamping member 241 is located outside the positioning opening 21031; in the process of rotating the connection joint 213 so that the clamping member 241 is inserted into the card slot 111, the clamping member 241 is located outside the positioning opening 21031 and is not installed in place, so that the clamping member 241 and the card slot 111 are also misaligned, resulting in the inability to install and fix the water treatment filter element 240.

[0226] The above structural design can ensure 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, thereby improving the user experience.

[0227] In another embodiment, in order to facilitate the installation of the connecting joint 213, a connecting seat 214 is provided on the outer shell 210, and a mounting socket 215 is provided at the end of the connecting seat 214, and the mounting socket is connected to the corresponding connecting channel, and a mounting hole (not marked) is provided on the side wall of the connecting seat 214, and a detachable limiting member 216 is provided in the mounting hole; the connecting joint 213 is provided with a plug, and a limiting groove 2131 is provided on the outer circumference of the plug, and the limiting member 216 is stuck in the limiting groove 2131.

[0228] Specifically, the connecting joint 213 is also installed on the outer shell 210 in an insertion manner, and the limiting member 216 and the limiting groove 2131 cooperate with each other. On the one hand, it satisfies the requirement that the connecting joint 213 is reliably connected to the outer shell 210 and will not be detached from the mounting socket. On the other hand, it can also meet the requirement that the connecting joint 213 can rotate relative to the outer shell 210.

[0229] The limiting member 216 is a U-shaped structure, and the side wall of the connection seat 214 is provided with two mounting holes, and 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 across the two sides of the connection joint 213, providing a more reliable limiting effect on the connection joint 213.

[0230] In addition, the position-limiting member 216 is also provided with a snap-fitting portion (not marked), and the connection seat 214 is provided with a snap-fitting portion, and the snap-fitting portion is snap-fitted on the snap-fitting portion. Specifically, after the position-limiting member 216 is installed in place, the snap-fitting portion and the snap-fitting portion are snap-fitted together to ensure that the position-limiting member 216 is firmly and reliably installed on the connection seat 214.

[0231] In another embodiment, in order to limit the rotation angle of the connecting joint 213, a raised rotation limit block 217 is provided in the mounting socket, and a limiting rib 2132 is provided on the outer circumference of the plug of the connecting joint 213, and the rotation limit block 217 is located between the two ends of the limiting rib 2132.

[0232] 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 maximum rotation angle position, the rotation limit block 217 will abut against the corresponding end of the limit rib 2132 .

[0233] Embodiment six, as Figure 24-Figure 30 As shown, the present invention also provides a wall-mounted bathing device, which includes:

[0234] A housing 100, on which a water inlet pipe 101 and a water outlet pipe 102 are disposed, and an installation space is formed inside the housing 100, in which a first installation seat 103 and a second installation seat 104 are disposed;

[0235] The water valve module has a water inlet interface 2101, a water outlet interface 2102, an external interface 2103 and the liquid suction port; wherein the water valve module is composed of a shell 210 and a temperature control valve core 220, a water circuit control valve core 230 and a regeneration valve core arranged on the shell 210.

[0236] A water treatment filter element 240, which is used to treat the water flowing into the water inlet pipe 101 and output it from the water outlet pipe 102;

[0237] The salt box is provided with a liquid suction tube;

[0238] Among them, the salt box, the water valve module, and the water treatment filter element 240 are all arranged in the casing 100, the valve module is arranged on the first mounting seat 103, the water treatment filter element 240 is arranged on the second mounting seat 104, the water inlet pipe 101 is connected to the water inlet interface 2101, the water outlet pipe 102 is connected to the water outlet interface 2102, the water treatment filter element 240 is connected to the external interface 2103, the liquid suction pipe is connected to the liquid suction port, and the casing 100 is used to hang on the water inlet pipe 101 and / or the water outlet pipe 102.

[0239] Specifically, in order to meet the requirements of bathroom installation, a wall-mounted housing 100 is used, and the housing 100 is suspended on the wall of the bathroom through the water inlet pipe 101 and / or the water outlet pipe 102, and the water valve module and the water treatment filter element 240 are centrally installed in the housing 100. Among them, the water valve module and the water treatment filter element 240 constitute the water treatment device 200 in the embodiment of the present application, and the specific structural form of the water valve module and the water treatment filter element 240 is not described here.

[0240] During the installation process in the user's home, the water inlet pipe 101 is connected to the water pipe network in the user's home. A water supply pipe opening is usually reserved on the wall of the user's home, and the water inlet pipe 101 is installed on the water supply pipe opening. Similarly, the water outlet pipe 102 is connected to the water pipe of the water use terminal in the user's home.

[0241] The following description will be made by taking the water inlet pipe 101 supporting the housing 100 as an example.

[0242] The water inlet pipe 101 is connected to the water supply pipe outlet buried in the wall of the user's home, the housing 100 is hung on the wall through the water inlet pipe 101, and the water valve module and the water treatment filter element 240 in the housing 100 are fixedly installed in the housing 100 through corresponding mounting seats.

[0243] The housing 100 is installed and hung on the wall through the water inlet pipe 101 or the water outlet pipe to meet the requirements of wall installation. At the same time, the water valve module and the water treatment filter element 240 are centrally installed in the housing 100 to achieve a compact structural design and meet the requirements of unified and rapid installation on site.

[0244] In some embodiments, the housing 100 has a flat structure as a whole. In this way, after the housing 100 is installed on the wall, since the housing 100 has a flat structure, the housing 100 can be close to the wall and use the area of ​​the wall to form an internal installation space to install the water valve module and the water treatment filter element 240. In addition, the housing 100 with a flat structure can reduce the amount of effective space occupied by the housing 100 in the bathroom, and reduce the user from bumping into the housing 100 during bathing. In addition, the housing 100 is integrated with a water valve module, and the height of the wall-mounted installation of the housing 100 will be suitable for the user to operate the water valve module, and then the housing 100 can be installed using the installation space where the mixing valve was originally installed in the user's home.

[0245] In one embodiment of the present application, the water inlet pipe 101 passes through the back plate of the housing 100 and extends to the outside of the housing 100 .

[0246] Specifically, the water inlet pipe 101 extends outward from the back plate of the housing 100 to connect to the water supply pipe on the wall of the user's home. Generally, the water inlet pipe 101 is arranged horizontally, which is more conducive to carrying the housing 100 and the water valve module and water treatment filter element 240 inside the housing 100 through the water inlet pipe 101. In addition, the water entering the water valve module is generally divided into cold water and hot water, so water inlet pipes 101 can be respectively configured on both sides of the housing 100, one of which is used to transport cold water, and the other is used to transport hot water.

[0247] In a certain embodiment, in order to facilitate on-site installation by operators, the water inlet pipe 101 includes a first tube body 1011 and a second tube body 1012, the first tube body 1011 is provided with an external threaded portion 1013, the axis of the external threaded portion 1013 is set to deviate from the axis of the first tube body 1011, the first tube body 1011 is sealed and inserted in the second tube body 1012, the external threaded portion 1013 is located outside the casing 100, and the second tube body 1012 is connected to the water inlet interface 2101.

[0248] Specifically, in the actual assembly process, due to the differences in the decoration construction of users' homes, the distances between the two pipe openings of the external water pipes that transport hot and cold water vary. By setting the external threaded portion 1013 of the first tube body 1011 in an off-axis arrangement, and then connecting it to the pipe opening on the wall through the external threaded portion 1013, and then rotating it at an appropriate angle so that the distance between the two first tube bodies 1011 meets the installation distance between the two second tube bodies 1012 fixedly installed on the casing 100, it is convenient for quick installation on site to improve the versatility of installation.

[0249] The first tube body 1011 and the second tube body 1012 are assembled in an insertion manner. After the installation position of the first tube body 1011 is adjusted, the first tube body 1011 is inserted into the corresponding second tube body 1012 to complete the assembly.

[0250] In another embodiment, in order to ensure a firm and reliable connection between the first tube body 1011 and the second tube body 1012, the outer diameter of the tube section of the first tube body 1011 inserted into the second tube body 1012 gradually increases from the outside to the inside, and a screw hole is provided on the tube wall of the second tube body 1012, and a locking screw 1014 is threadedly connected in the screw hole, and the locking screw 1014 is against the outer tube wall of the first tube body 1011.

[0251] Specifically, when installing in the user's home, after the two first tubes 1011 are installed and adjusted, the housing 100 is connected to the first tube 1011 on the wall through the second tube 1012. And, after the first tube 1011 is inserted into the second tube 1012 and the distance between the housing 100 and the wall is adjusted, the first tube 1011 is fastened to the second tube 1012 by the locking screw 1014.

[0252] Since the size of the outer tube wall of the first tube body 1011 is a variable diameter structure, the larger the diameter of the outer tube wall of the first tube body 1011 inserted into the second tube body 1012, the locking screw 1014 can be tightened so that the end of the locking screw 1014 abuts against the outer tube wall of the first tube body 1011, thereby preventing the first tube body 1011 from detaching from the second tube body 1012, thereby improving the connection reliability between the first tube body 1011 and the second tube body 1012.

[0253] At the same time, the first tube body 1011 is connected to the second tube body 1012 by means of the locking screw 1014 cooperating with the outer tube wall of the first tube body 1011, and the outer tube wall variable diameter structure of the first tube body 1011 is used to enable the casing 100 to be installed tightly against the wall.

[0254] In addition, in order to facilitate the operator to operate the locking screw 1014, an operation hole 130 can be provided on the housing 100, and the operation hole 130 is arranged opposite to the locking screw 1014. Specifically, in the actual installation process, after the position between the first tube 1011 and the second tube 1012 is adjusted, the first tube 1011 and the second tube 1012 can be tightened by the locking screw 1014. Since the second tube 1012 is located in the housing 100, the operator inserts a screwdriver into the operation hole 130 to tighten the locking screw 1014.

[0255] As for the water treatment filter element 240 and the salt box, two water treatment filter elements 240 are distributed on both sides of the salt box. Among them, since the water treatment filter element 240 is usually a cylindrical structure, in order to fully utilize the space in the housing 100 to increase the volume of the salt box, a concave structure (not marked) is formed on both sides of the salt box, and the water treatment filter element is located in the concave structure on the corresponding side.

[0256] In some embodiments, the housing 100 includes a front cover 1, a rear shell 2 and an upper cover 3, wherein the front cover is disposed on the rear shell 2, an installation cavity is formed between the front cover and the rear shell 2, and the upper cover 3 is disposed at the upper end of the rear shell 2.

[0257] In order to conveniently install the salt box, a hook 51 is provided on the back of the salt box, 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 .

[0258] Specifically, when the salt box is installed on the housing 100, the front cover is opened, and the salt box is inserted into the hanging hole 140 through the hook so that the salt box is hung in the housing 100. In addition, the salt box can be further fastened in the housing 100 by screws as needed.

[0259] In some embodiments, since salt needs to be added to the salt box regularly, in order to facilitate the user to perform the salt adding operation, a filling port (not marked) is provided on the front cover, and the filling port is located above the salt box.

[0260] Specifically, the top of the salt box is an open structure. When salt needs to be added to the salt box, the user can add salt to the salt box in the housing 100 from the filling port without punching the housing 100 .

[0261] In some embodiments, the filling port is provided with a door body 11 that can be opened and closed. The lower part of the door body 11 is hinged on the housing 100, and raised material guide ribs 12 are provided on both sides of the inner wall of the door body 11. The two material guide ribs 12 gradually move together downward, and the lower ends of the two material guide ribs 12 form a discharge port.

[0262] Specifically, in actual operation, after the user opens the door body 11 , the door body 11 is arranged as a whole to tilt outward from bottom to top, and the user can introduce salt into the salt box in the housing 100 through the door body 11 .

[0263] During the pouring process of the salt, the guide ribs 1212 arranged on both sides of the door body 11 can guide the salt to accurately slide into the salt box below.

[0264] Based on the above technical solution, optional, such as 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 convenient disassembly and assembly, a support portion 120 can be configured in the casing 100; the water treatment filter element 240 is inserted into the external interface 2103 through the plug-in water pipe at its end, and the other end of the water treatment filter element 240 rests on the support portion 120.

[0265] 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 by plugging in the water pipe, the other end of the water treatment filter element 240 rests on the support portion 120 configured on the casing 100, and the other end of the water treatment filter element 240 can also be supported by the support portion 120.

[0266] The two ends of the water treatment filter element 240 are respectively supported and fixed, so that during use, the water treatment filter element 240 can be effectively reduced from falling off due to shaking, thereby improving the reliability of use; in addition, during the installation or disassembly of the water treatment filter element 240, by pushing and pulling 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, thereby meeting the requirements of convenient disassembly and assembly.

[0267] 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 .

[0268] Specifically, the support portion 120 adopts an elastic plate so that the support portion 120 has a certain 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 to cause the elastic plate to produce a certain deformation, and then the elastic plate is used to provide reliable support for the water treatment filter element 240.

[0269] During disassembly, the elasticity of the elastic plate can be overcome and the requirement for easy disassembly of the water treatment filter element 240 can be met.

[0270] In one embodiment, the surface of the elastic plate in contact with the end of the water treatment filter element 240 forms an inclined surface 121 and a supporting surface 122 which are connected in sequence.

[0271] Specifically, the inclined surface 121 can facilitate the end of the water treatment filter element 240 to move through the inclined surface 121 when the water treatment filter element 240 is installed, 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, in order to facilitate processing and reduce manufacturing costs, the elastic plate and the housing 100 are an integrated structure.

[0272] 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 further provided on both sides of the support portion 120 , and the filter element is located between the two limiting portions 123 .

[0273] Specifically, the limiting parts on both sides of the support part 120 form a limiting space, which can limit the end position of the water treatment filter element 240 in contact with the support part 120 to the limiting space, thereby improving the installation reliability.

[0274] In some embodiments, at least one second mounting seat 104 may be provided on the housing 100 along the length direction of the filter element, and a recessed portion is formed on the second mounting seat 104, and the water treatment filter element 240 is located in the recessed portion.

[0275] 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 configured with at least one second mounting seat 104 in its length direction. The recessed portion formed by the second mounting seat 104 can further position and support the middle area of ​​the water treatment filter element 240, thereby being more conducive to improving installation reliability.
