[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] This utility model discloses a water softener, such as Figures 1 to 4As shown, the water softener includes a resin tank 100, an adapter 200, a control valve 300, and pipe fittings 400. The resin tank 100 is mainly used to hold resin for softening raw water. The resin tank 100 extends vertically and forms a resin cavity within it to accommodate the softening resin. The resin tank 100 has a top opening that communicates with the resin cavity. The adapter 200 has a water passage that communicates with the resin cavity. Raw water and brine can be introduced into the resin tank 100 through the water passage, and softened water and wastewater can flow out of the resin tank 100. In this embodiment of the invention, the adapter 200 is installed at the top opening. The control valve 300 is located laterally on the side of the resin tank 100. The control valve 300 located on the lateral side of the resin tank 100 can be connected to the adapter 200 located on the top of the resin tank 100 by means of the pipe fitting 400. Specifically, the first end of the pipe fitting 400 is detachably connected to the valve port at the top of the control valve 300, and the second end of the pipe fitting 400 is connected to the port of the adapter 200.

[0036] Compared to existing water softeners where the control valve is located at the top of the resin tank, the water softener provided by this invention places the control valve 300 on the lateral side of the resin tank 100. This prevents the control valve 300 from occupying vertical space in the installation area of ​​the water softener. This arrangement allows for a higher resin tank 100, increasing the capacity of the resin chamber and thus holding more softening resin, thereby enhancing the softening capacity of the water softener. Furthermore, the side-mounted control valve 300 and its detachable connection to the pipe fitting 400 facilitate easy assembly and disassembly of the control valve 300, making maintenance and replacement easier. In addition, the separate design of the control valve 300 and the pipe fitting 400 reduces manufacturing difficulty, as a one-piece molded control valve 300 and pipe fitting 400 are difficult to demold and significantly increase manufacturing complexity.

[0037] Continue to refer to Figure 1 and Figure 3As shown, the resin tank 100 is cylindrical. A water distributor assembly is installed inside the resin tank 100, forming a space for resin containment between the water distributor assembly and the inner wall of the resin tank 100. The water distributor assembly includes an upper water distributor 110, a lower water distributor 130, and a central pipe 120. The upper water distributor 110 is located at the top of the central pipe 120 and extends radially upwards along the resin tank 100, serving to distribute water radially within the resin tank 100. This allows the raw water to first distribute across the cross-section of the resin tank 100 before entering the resin from top to bottom. The upper water distributor 110 helps improve the softening effect and efficiency of the water. Softened water, formed by softening with the resin, flows out of the resin tank 100 from bottom to top through the central pipe 120. If the resin in the resin tank 100 needs to be regenerated, the brine can flow from top to bottom through the central pipe 120 and enter the resin after passing through the lower water distributor 130. The brine can regenerate the resin by flowing from bottom to top in the resin, and the wastewater generated can be discharged from the resin tank 100.

[0038] Continue to refer to Figure 1 and Figure 3 As shown, the adapter 200 includes a first straight pipe section 210, a second straight pipe section 220, a round pipe section 230, and a mounting section 240. The round pipe section 230 is formed between the first straight pipe section 210 and the second straight pipe section 220. A first water passage is formed in the first straight pipe section 210, a second water passage is formed in the second straight pipe section 220, a third water passage is formed in the round pipe section 230, and a fourth water passage is formed in the mounting section 240. The first water passage and the fourth water passage are connected, and the fourth water passage is connected to the water distribution trough in the upper water distributor 110. The raw water entering the first water passage flows sequentially through the fourth water passage and the water distribution trough of the upper water distributor 110 into the resin. The second water passage and the third water passage are connected, and the third water passage is connected to the cavity of the central pipe 120. Soft water flowing out from the central pipe 120 is discharged through the third water passage and the second water passage.

[0039] The mounting part 240 is formed below the first straight tube part 210, the second straight tube part 220 and the round tube part 230. The mounting part 240 is used to connect with the top of the resin tank 100. Optionally, the mounting part 240 is provided with an external thread structure and the top opening of the resin tank 100 is provided with an internal thread structure. The external thread structure and the internal thread structure cooperate to realize the threaded connection between the resin tank 100 and the adapter 200.

[0040] The control valve 300 is equipped with a raw water passage and a soft water passage that are connected to the first water passage and the second water passage, as well as a brine passage that is connected to the brine tank and a waste discharge passage for wastewater discharge. The control valve 300 is also equipped with a control component for controlling the opening and closing of each passage. The structure of the control component is existing technology and will not be described in detail here.

[0041] In some embodiments, the pipe fitting 400 has an L-shaped pipe structure. The bottom end of the pipe fitting 400 is the first end, and the top end of the pipe fitting 400 is the second end. In a specific embodiment, referring to... Figure 2 As shown, the top surface of the control valve 300 is basically flush with the top surface of the pipe fitting 400. This arrangement makes the structure of the water softener more regular and makes it easier to utilize the under-sink space.

[0042] Continue to refer to Figure 4 As shown, the top valve port includes a raw water outlet valve port 303 and a soft water inlet valve port 304. The raw water outlet valve port 303 is a valve port on the raw water passage used to connect to the pipe fitting connector 400, and the soft water inlet valve port 304 is a valve port on the soft water passage used to connect to the pipe fitting connector 400. (Continue referring to...) Figure 1 As shown, the pipe fitting 400 includes a first pipe fitting 410 and a second pipe fitting 420. The adapter 200 has two first ports. The first pipe fitting 410 is connected between the raw water outlet valve 303 and one of the first ports, and the second pipe fitting 420 is connected between the soft water inlet valve 304 and the other first port.

[0043] To enable quick connection and disconnection between the pipe fitting 400 and the control valve 300, in some embodiments, the water softener further includes a first quick-connect clamp 500. The first end of the pipe fitting 400 has a first annular groove 401 circumferentially arranged, and the top valve port of the control valve 300 has a first slot 301. The first end of the pipe fitting 400 is inserted into the top valve port, and the first annular groove 401 communicates with the first slot 301. The first quick-connect clamp 500 is simultaneously inserted into both the first slot 301 and the first annular groove 401. Of course, besides using the first quick-connect clamp 500 to achieve a detachable connection between the pipe fitting 400 and the control valve 300, other methods can also be used to achieve a detachable connection, such as a threaded connection.

[0044] Specifically, continue to participate Figure 4 As shown, the first pipe connector 410 has a first annular groove 401 circumferentially provided at its first end, and a first slot 301 is provided at the raw water outlet valve 303. The first end of the first pipe connector 410 is inserted into the raw water outlet valve 303, and the first annular groove 401 communicates with the first slot 301. A first quick-connect clamp 500 is simultaneously inserted into the first slot 301 and the first annular groove 401. The second pipe connector 420 has a first annular groove 401 circumferentially provided at its first end, and a first slot 301 is provided at the soft water inlet valve 304. The first end of the second pipe connector 420 is inserted into the soft water inlet valve 304, and the first annular groove 401 communicates with the first slot 301. Another first quick-connect clamp 500 is simultaneously inserted into the first slot 301 and the first annular groove 401.

[0045] Regarding the structure of the first quick-connect clamp 500, in some embodiments, such as Figure 5As shown, the first quick-connect clamp 500 is a U-shaped clamp with two insertion portions 510. Two first slots 301 are provided, located on opposite sides of the first annular groove 401. The two insertion portions 510 are inserted into the two first slots 301 in a one-to-one correspondence. This arrangement helps improve the connection stability between the control valve 300 and the pipe fitting 400. Of course, in other embodiments, the first quick-connect clamp 500 can also be of other shapes, such as a straight clamp or an L-shaped clamp.

[0046] Furthermore, continue to refer to Figure 4 and Figure 5 As shown, in some embodiments, a positioning slot 302 is provided on one of the top valve port of the control valve 300 and the first quick-connect clamp 500, and a positioning protrusion 520 is provided on the other. The positioning protrusion 520 is inserted into the positioning slot 302. This arrangement can improve the installation stability of the first quick-connect clamp 500 on the control valve 300 and improve the speed and accuracy of assembling the first quick-connect clamp 500 and the control valve 300. Optionally, the positioning protrusion 520 includes two opposing elastic protrusions. When the positioning protrusion 520 is pushed into the positioning slot 302 by the elastic protrusions, the elastic protrusions rebound after the positioning protrusion 520 is inserted into the positioning slot 302, which can improve its engagement strength with the positioning slot 302. This arrangement is beneficial to further improve the connection stability between the control valve 300 and the pipe fitting 400.

[0047] The adapter 200 has a first port, which is detachably connected to the second end of the pipe fitting 400. By separating the adapter 200 and the pipe fitting 400, it is easier to manufacture both. An integrally molded adapter 200 and pipe fitting 400 would be difficult to demold and much more difficult to manufacture.

[0048] In some embodiments, continue to refer to Figure 1 As shown, the water softener also includes a second quick-connect clamp 600. A second annular groove is provided circumferentially at the second end of the pipe fitting 400, and a second slot is provided at the first port of the adapter 200. The second end of the pipe fitting 400 is inserted into the adapter 200, and the second annular groove communicates with the second slot. The second quick-connect clamp 600 is simultaneously inserted into both the second slot and the second annular groove. Of course, besides using the second quick-connect clamp 600 to achieve a detachable connection between the adapter 200 and the pipe fitting 400, other methods can also be used to achieve a detachable connection, such as a threaded connection.

[0049] It should be noted that one end of the first water passage in the first straight pipe section 210 forms a first port, and one end of the second water passage in the second straight pipe section 220 also forms a first port. The top end of the first pipe connector 410 is detachably connected to the first port of the first water passage through a second quick-connect clamp 600, and the top end of the second pipe connector 420 is detachably connected to the first port of the second water passage through another second quick-connect clamp 600.

[0050] The structure of the second quick-connect clamp 600 can be the same as that of the first quick-connect clamp 500, so it will not be described in detail here; of course, the structure of the second quick-connect clamp 600 can also be different from that of the first quick-connect clamp 500.

[0051] In some embodiments, a first water passage is provided through a first straight pipe section 210, and a second water passage is provided through a second straight pipe section 220. Therefore, the first water passage forms a second port at the end furthest from its first port, and the second water passage also forms a second port at the end furthest from its first port. It should be noted that the second end of the pipe fitting 400 can be selectively connected to either the first port or the second port. This arrangement ensures that if one of the first or second ports fails, the other intact port can still be used to connect to the pipe fitting 400. Furthermore, if both the first and second ports are functioning correctly, one of the first and second ports can be connected to the pipe fitting 400, while the other can be connected to another resin tank 100.

[0052] In one specific embodiment, continue to refer to Figure 1 As shown, the second end of the pipe fitting 400 is connected to the first port. The water softener also includes a plug 700, which is detachably installed inside the second port. The second port, when open, can be connected to another resin tank 100. If the water softener requires two or more resin tanks 100, the plug 700 can be directly removed to open the second port, thus connecting the pipe fitting 400 to another resin tank 100. If the water softener only requires one resin tank 100, the plug 700 can be installed at the second port to seal it.

[0053] In some embodiments, continue to refer to Figure 1 As shown, the water softener also includes a third quick-connect clamp 800, a third annular groove along the circumference of the plug 700, and a third slot at the second port of the adapter 200. The plug 700 is inserted into the second port, and the third annular groove communicates with the third slot. The third quick-connect clamp 800 is simultaneously inserted into both the third slot and the third annular groove. Of course, besides using the third quick-connect clamp 800 to achieve a detachable connection between the adapter 200 and the plug 700, other methods can also be used to achieve a detachable connection, such as a threaded connection.

[0054] Regarding the structure of the third quick-connect clamp 800, it can be the same as the structure of the second quick-connect clamp 600 and the first quick-connect clamp 500, so it will not be described in detail here; of course, the structure of the third quick-connect clamp 800 can also be different from the structure of the second quick-connect clamp 600 and the first quick-connect clamp 500.

[0055] Continue to refer to Figure 1 As shown, in some embodiments, the control valve 300 further includes a bottom valve port, which includes an inlet valve port and an outlet valve port. The water softener also includes a raw water inlet connector 900, which is detachably connected to the inlet valve port via a fourth quick-connect clamp 920. Specifically, the raw water inlet connector 900 has a fourth annular groove along its circumference, and a fourth slot is provided at the inlet valve port. The top of the raw water inlet connector 900 is inserted into the inlet valve port, the fourth annular groove communicates with the fourth slot, and the fourth quick-connect clamp 920 is simultaneously inserted into both the fourth slot and the fourth annular groove.

[0056] Regarding the structure of the fourth quick-connect clamp 920, it can be the same as the structure of the third quick-connect clamp 800, the second quick-connect clamp 600, and the first quick-connect clamp 500, so it will not be described in detail here; of course, the structure of the fourth quick-connect clamp 920 can also be different from the structure of the third quick-connect clamp 800, the second quick-connect clamp 600, and the first quick-connect clamp 500.

[0057] Continue to refer to Figure 1 As shown, the water softener also includes a soft water outlet connector 930, which is detachably connected to the outlet valve via a fifth quick-connect clamp 940. Specifically, the soft water outlet connector 930 has a fifth annular groove along its circumference, and a fifth slot is provided at the outlet valve. The top of the soft water outlet connector 930 is inserted into the outlet valve, and the fifth annular groove and the fifth slot are connected. The fifth quick-connect clamp 940 is simultaneously inserted into both the fifth slot and the fifth annular groove.

[0058] Regarding the structure of the fifth quick-connect clamp 940, it can be the same as the structure of the fourth quick-connect clamp 920, the third quick-connect clamp 800, the second quick-connect clamp 600, and the first quick-connect clamp 500, so it will not be described in detail here; of course, the structure of the fifth quick-connect clamp 940 can also be different from the structure of the fourth quick-connect clamp 920, the third quick-connect clamp 800, the second quick-connect clamp 600, and the first quick-connect clamp 500.

[0059] In embodiments of this utility model, the water softener also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the control valve 300 and other electrical control components of the water softener to achieve their functions.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
