[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] like Figures 1 to 3 As shown, this embodiment first provides a water treatment device, which includes a first treatment tank 1, a second treatment tank 2, and a connecting valve 3. The water treatment device includes, but is not limited to, a water softener, and can also be a water purifier. When the water treatment device is a water softener, the first treatment tank 1 and the second treatment tank 2 can be softening tanks with soft water filter elements such as resin filter elements; when the water treatment device is a water purifier, the first treatment tank 1 and the second treatment tank 2 can be purification tanks with purification filter elements such as RO membrane reverse osmosis filter elements.

[0039] The first treatment tank 1 has a first connecting port 13 and a first pipe joint 11, and the second treatment tank 2 has a second connecting port 23 and a second pipe joint 21. The connecting valve 3 connects the first connecting port 13 and the second connecting port 23. The connecting valve 3 is used to connect the external water supply end and the external water use end. The raw water supplied by the external water supply end enters the first treatment tank 1 and the second treatment tank 2 through the connecting valve 3 for softening. The softened water formed after softening flows back into the connecting valve 3 to supply the external water use end. The opening of the first pipe connector 11 is oriented opposite to the opening of the second pipe connector 21, and the first pipe connector 11 and the second pipe connector 21 are detachably connected. By aligning the opening of the first pipe connector 11 with the opening of the second pipe connector 21, a detachable connection can be made between the first pipe connector 11 and the second pipe connector 21, thereby forming a series connection between the first treatment tank 1 and the second treatment tank 2. No additional connecting pipe is required, reducing the number of parts, reducing the space occupied, and simplifying assembly. Moreover, the connecting valve 3 only needs to realize the connection between the external water supply end, the external water use end, and the first treatment tank 1 and the second treatment tank 2. The water flow between the first treatment tank 1 and the second treatment tank 2 does not need to pass through the connecting valve 3, thereby simplifying the valve body structure of the connecting valve 3, reducing the production cost of the connecting valve 3, and improving the convenience of maintenance.

[0040] For the first treatment tank 1 and the second treatment tank 2 connected in series, the raw water can enter the first treatment tank 1 first or the second treatment tank 2 first; this embodiment does not impose specific restrictions. For example, in one embodiment, the raw water from the external water supply end enters the first treatment tank 1 first through the connecting valve 3 and the first connecting port 13. After being softened in the first treatment tank 1, it enters the second treatment tank 2 through the first pipe joint 11 and the second pipe joint 21. After being softened in the second treatment tank 2, it is supplied to the external water user through the second connecting port 23 and the connecting valve 3.

[0041] likeFigure 4 As shown, the first treatment tank 1 and the second treatment tank 2 are arranged side by side, the first pipe joint 11 is arranged at the upper end of the first treatment tank 1, and the second pipe joint 21 is arranged at the upper end of the second treatment tank 2, so that the structure is relatively compact.

[0042] Regarding the detachable connection structure of the first pipe joint 11 and the second pipe joint 21, one of the first pipe joint 11 and the second pipe joint 21 is inserted into the other. Exemplarily, in an embodiment, the second pipe joint 21 is inserted into the first pipe joint 11, and at the same time, in order to increase the sealing performance and connection reliability of the connection, a pipe clamp 6 is arranged at the connection of the first pipe joint 11 and the second pipe joint 21. Such a quick insertion structure increases the convenience of connection, and connection can be achieved without screwing.

[0043] The upper end cover of the first treatment tank 1 has a first protruding portion 12 protruding in the axial direction, one end of the first pipe joint 11 is connected to the side wall of the first protruding portion 12, the upper end cover of the second treatment tank 2 has a second protruding portion 22 protruding in the axial direction, one end of the second pipe joint 21 is connected to the side wall of the second protruding portion 22, and the first pipe joint 11 and the second pipe joint 21 are arranged in a straight line and coaxially, as shown. Figure 4

[0044] The first protruding portion 12 is formed by protruding in the axial direction from part of the upper end cover of the first treatment tank 1, so that the radial dimension of the first protruding portion 12 is smaller than the radial dimension of the first treatment tank 1; similarly, the second protruding portion 22 is formed by protruding in the axial direction from part of the upper end cover of the second treatment tank 2, so that the radial dimension of the second protruding portion 22 is smaller than the radial dimension of the second treatment tank 2. The first protruding portion 12 increases the space in the tank of the first treatment tank 1, and the second protruding portion 22 increases the space in the tank of the second treatment tank 2, which can respectively accommodate larger volume filter cartridges to form longer flow channels, thereby improving the softening effect or purification effect. Moreover, the arrangement of the first protruding portion 12 and the second protruding portion 22 provides more convenience for the arrangement of the first pipe joint 11 and the second pipe joint 21, on the one hand, so that the first pipe joint 11 and the second pipe joint 21 can be arranged in a straight line to ensure coaxial arrangement, without the need for turning through an elbow pipe, and the first pipe joint 11 and the second pipe joint 21 can be arranged in a smaller length, thereby reducing water flow resistance; on the other hand, the first pipe joint 11 and the second pipe joint 21 can be arranged by using the space between the first protruding portion 12 and the second protruding portion 22, so that the axial spacing between the first treatment tank 1 and the second treatment tank 2 is reduced, which is beneficial to the compactness and miniaturization of the water treatment device.

[0045] ​In an embodiment, the first communication port 13 is formed in the upper end cover of the first treatment tank 1, the second communication port 23 is formed in the upper end cover of the second treatment tank 2, and the communication valve 3 is located above the first treatment tank 1 and the second treatment tank 2 to communicate the first communication port 13 and the second communication port 23. The communication valve 3 is detachably connected with the first treatment tank 1 and the second treatment tank 2, and the installation and maintenance of the communication valve 3 can be performed from above the first treatment tank 1 and the second treatment tank 2. The first pipe joint 11 and the second pipe joint 21 are located below the communication valve 3, and in the width direction of the communication valve 3, the first pipe joint 11 and the second pipe joint 21 are located within the width range of the communication valve 3, thereby improving the compactness of the structure.

[0046] As shown in Figure 5 In order to avoid the first communication port 13 formed in the upper end cover of the first treatment tank 1, the first protruding portion 12 is in the shape of a sector, and the first communication port 13 is located beside the first protruding portion 12. Similarly, the second protruding portion 22 is in the shape of a sector to avoid the second communication port 23 formed in the upper end cover of the second treatment tank 2, and the second communication port 23 is located beside the second protruding portion 22. In an embodiment, along the flow direction of raw water, the first treatment tank 1 and the second treatment tank 2 each have a water inlet channel and a water outlet channel, raw water enters the tank through the water inlet channel and flows out through the water outlet channel after being treated by the filter element. The water outlet channel is located in the central region of the tank and extends in the axial direction, and the water inlet channel is located in the edge region of the tank and extends in the axial direction around the periphery of the water outlet channel. For the first treatment tank 1, one of the first communication port 13 and the first pipe joint 11 communicates the water inlet channel, and the other communicates the water outlet channel; similarly, for the second treatment tank 2, one of the second communication port 23 and the second pipe joint 21 communicates the water inlet channel, and the other communicates the water outlet channel. Therefore, the arrangement position of the first communication port 13 and the first protruding portion 12 on the upper end cover is determined by the flow direction of water, and the arrangement position of the second communication port 23 and the second protruding portion 22 on the upper end cover is also determined by the flow direction of water. For example, in an embodiment, raw water from the external water supply enters the first treatment tank 1 through the communication valve 3 and the first communication port 13, and therefore, for the first treatment tank 1, the first communication port 13 communicates the water inlet channel and is arranged at the edge of the upper end cover, and correspondingly, the first protruding portion 12 is in the shape of a 180° sector and covers the center of the upper end cover, thereby facilitating the first pipe joint 11 to communicate the water outlet channel in the central region of the tank; for the second treatment tank 2, the second communication port 23 communicates the water outlet channel and is formed in the center of the upper end cover, and the second protruding portion 22 is in the shape of a 180° sector and is arranged eccentrically relative to the upper end cover, on the one hand to avoid the second communication port 23 in the center, and on the other hand to extend to the edge of the upper end cover to facilitate the second pipe joint 21 to communicate the water inlet channel in the edge region of the tank.

[0047] Further, the first communication port 13 and the second communication port 23 are located on the same side of the common axis of the first pipe joint 11 and the second pipe joint 21, avoiding interference of the installation of the communication valve 3 and the first pipe joint 11 and the second pipe joint 21. Preferably, the line connecting the centers of the first communication port 13 and the second communication port 23 is arranged parallel to the common axis of the first pipe joint 11 and the second pipe joint 21.

[0048] The sector central angle of the first protruding part 12 and the second protruding part 22 can be adjusted, for example, 90° sector or 120° sector, not limited to the drawings of the embodiment.

[0049] In order to increase the convenience of the installation and removal of the communication valve 3 from above, the first treatment tank 1 has a first installation joint 14 forming the first communication port 13, the second treatment tank 2 has a second installation joint 24 forming the second communication port 23, the communication valve 3 has a first communication joint 391 and a second communication joint 392, the first installation joint 14 and the first communication joint 391 are detachably connected, and the second installation joint 24 and the second communication joint 392 are detachably connected, to form the communication of the communication valve 3 and the first treatment tank 1 and the second treatment tank 2.

[0050] Specifically, as shown in the drawings, Figure 6 the first communication joint 391 is inserted into the first installation joint 14, and the second communication joint 392 is inserted into the second installation joint 24. This quick insertion structure improves the convenience of the connection of the communication valve 3 and the first treatment tank 1 and the second treatment tank 2, without the need for screwing operation, and the installation of the communication valve 3 can be performed from above the first treatment tank 1 and the second treatment tank 2. The connection between the first communication joint 391 and the first installation joint 14 and the connection between the second communication joint 392 and the second installation joint 24 can be sealed by sealing glue. In addition, pipe clamps 6 are respectively clamped at the connection between the first communication joint 391 and the first installation joint 14 and the connection between the second communication joint 392 and the second installation joint 24, to increase the connection reliability of the connections.

[0051] The communication valve 3 has a water inlet 31 for communicating with an external water supply end and a water outlet 32 for communicating with an external water use end, and the water inlet 31 and the water outlet 32 can be selectively communicated. In normal use of the water treatment device, the water inlet 31 and the water outlet 32 are in a non-communication state; when the water treatment device needs to be stopped for failure, maintenance, etc., the water inlet 31 and the water outlet 32 can form communication, and the raw water of the external water supply end will flow out through the water inlet 31 and the water outlet 32, and will not flow into the communication valve 3.

[0052] Specifically, the communication valve 3 has a first switch 33 and a second switch 34. When the first switch 33 and the second switch 34 are in a first working state, the water inlet 31 and the water outlet 32 are communicated with the first communication port 13 and the second communication port 23, respectively. When the first switch 33 and the second switch 34 are in a second working state, the water inlet 31 is communicated with the water outlet 32. Rotating the first switch 33 and the second switch 34 can realize the conversion between the first working state and the second working state, which is more convenient.

[0053] The first treatment tank 1 and the second treatment tank 2 are both provided with resin filter elements, and the raw water is softened by the resin filter elements. After a long time of use, the resin filter elements will be saturated and their softening capacity will decrease. In order to regenerate the resin filter elements, the water treatment device further comprises a salt tank 5, which contains brine. The communication valve 3 has a salt supplement port 36, and the salt tank 5 can selectively communicate with the salt supplement port 36. The brine is used to regenerate the resin filter elements. A hose is installed between the opening of the salt tank 5 and the salt supplement port 36. The opening and closing of the salt supplement port 36 are controlled by a switch, and then the flow direction of the brine to the communication valve 3 is controlled. After mixing with the raw water, the brine is used to regenerate the resin filter elements in the first treatment tank 1 and the second treatment tank 2.

[0054] The water treatment device is further provided with a salt shortage warning device 51. When the salt tank 5 is short of salt and cannot provide enough brine, the salt shortage warning device 51 can send a warning signal to remind the user. The structure of the salt shortage warning device 51 can be set according to the prior art, which will not be described here in detail.

[0055] In order to improve the protection performance, the water treatment device further comprises a shell assembly 4, which has a mounting cavity. The shell assembly 4 covers the first treatment tank 1, the second treatment tank 2 and the communication valve 3. Part of the communication valve 3 extends outside the mounting cavity to communicate with the external water supply end and the external water use end.

[0056] Specifically, the shell assembly 4 comprises a main shell 41 and at least one cover 42. The cover 42 is detachably connected to the main shell 41. The cover 42 and the main shell 41 surround to form a mounting cavity. The first treatment tank 1, the second treatment tank 2 and the communication valve 3 are arranged in the mounting cavity. For example, in an embodiment, the shell assembly 4 comprises three covers 42. One of the covers 42 covers the first switch 33 and the second switch 34. Another cover 42 covers the communication valve 3. The third cover 42 covers the opening of the salt tank 5. Opening the corresponding cover 42 can install and maintain the above-mentioned structural members, which is convenient to use. Similarly, detaching the main shell 41 can install and replace the first treatment tank 1 and the second treatment tank 2.

[0057] According to the different structural sizes of the first switch 33, the second switch 34, the communication valve 3 and the salt tank 5, the sizes and shapes of the plurality of covers 42 are slightly different. The embodiments of the present application are only illustrative, not limiting.

[0058] The water treatment device further comprises a support base plate 43, which separates the installation cavity into a first installation cavity and a second installation cavity, and is provided with an installation gap 431. The first treatment tank 1, the second treatment tank 2 and the salt tank 5 are located in the first installation cavity, and the communication valve 3 is located in the second installation cavity. The communication valve 3 and the first treatment tank 1 and the second treatment tank 2 are connected through the installation gap 431. On the one hand, the communication valve 3, the first treatment tank 1, the second treatment tank 2 and the salt tank 5 are separated by the support base plate 43, reducing the influence between them during the working process of the water treatment device, such as reducing the risk of water flowing to the first treatment tank 1, the second treatment tank 2 and the salt tank 5 when the communication valve 3 leaks; on the other hand, the support base plate 43 provides an assembly reference to ensure the fixation of the first treatment tank 1 and the second treatment tank 2. As shown in Figure 7 The support base plate 43 has grooves accommodating the first protruding part 12 and the second protruding part 22, and has the installation gap 431 to facilitate the first installation joint 14 and the second installation joint 24 to pass through and connect the communication valve 3 located on the other side of the support base plate 43. The first protruding part 12 and the first protruding part 12 are respectively embedded in the corresponding grooves, and the first pipe joint 11 and the second pipe joint 21 are already aligned and inserted, improving the positional accuracy of the connection.

[0059] The water treatment device is further provided with a waist belt ring 44, which is annularly arranged on the outer circumferential side of the first treatment tank 1 and the second treatment tank 2, and the width extends along the axial direction of the first treatment tank 1 and the second treatment tank 2. The annular arrangement of the waist belt ring 44 can reduce the risk of shaking of the first treatment tank 1 and the second treatment tank 2.

[0060] In order to further simplify the structure, the support base plate 43 is connected to the upper end of the waist belt ring 44 on the side facing the first treatment tank 1 and the second treatment tank 2, forming an integrated structure, which is convenient for assembly.

[0061] After a long time of use of the water treatment device, the first treatment tank 1 and the second treatment tank 2 need to be flushed. The communication valve 3 is further provided with a selectively opened blowdown port 35, and the raw water of the external water end can flush the first treatment tank 1 and the second treatment tank 2 to form sewage, and the blowdown port 35 is used to discharge the sewage. A hose is inserted at the blowdown port 35 to lead out the sewage.

[0062] The communication valve 3 comprises a first valve body 37 and a second valve body 38, as shown in Figure 8As shown, the first valve body 37 and the second valve body 38 are connected with each other in a buckling manner. Exemplarily, in an embodiment, the first valve body 37 is located at the upper side, and the first switch 33 and the second switch 34, the water inlet 31 and the water outlet 32 are all arranged on the first valve body 37; the first switch 33 and the second switch 34; the second valve body 38 is located at the lower side, and the first connecting joint 391 and the second connecting joint 392 are all arranged on the second valve body 38.
