[0008] A valve core is movably disposed in the seat body, the valve core is provided with a connecting cavity, and the valve core has a blocking position and an open position;

[0009] When the valve core is in the blocking position, the water inlet chamber and the water outlet chamber are both separated from the communicating channel and are both connected to the connecting chamber; when the valve core is in the open position, the water inlet chamber and the water outlet chamber are both connected to the communicating channel and are separated from the connecting chamber.

[0010] In one embodiment, the seat body further includes a receiving cavity communicated with the water inlet cavity and the water outlet cavity, and the valve core includes a valve body movably disposed in the receiving cavity, and a first column and a second column spaced apart from the valve body;

[0011] When the valve core is in the blocking position, the first cylinder and the second cylinder block the two openings of the communication channel; when the valve core is in the opening position, the first cylinder and the second cylinder open the two openings of the communication channel.

[0012] In one embodiment, the first column is provided with two first sealing members spaced apart and resting against the inner wall of the water inlet cavity, and the second column is provided with two second sealing members spaced apart and resting against the inner wall of the water outlet cavity;

[0013] When the valve core is in the blocking position, the two first seals are respectively located on both sides of the communicating channel, and the two second seals are respectively located on both sides of the communicating channel; when the valve core is in the open position, the two first seals and the two second seals are both located on the side of the communicating channel close to the accommodating chamber.

[0014] In one embodiment, the first column and the second column are both provided with a water passage, and each of the water passages is provided with a valve stem;

[0015] When the valve core is in the blocking position, the filter unit lifts up each valve stem to connect the water inlet chamber and the connecting chamber, and connect the water outlet chamber and the connecting chamber; when the valve core is in the open position, the valve stem blocks the water passage to separate the water inlet chamber and the connecting chamber, and separate the water outlet chamber and the connecting chamber.

[0016] In one embodiment, the water passage has a first communication cavity, and the valve stem is provided with a tapered surface;

[0017] When the valve core is in the open position, the conical surface abuts against the inner wall of the first communicating cavity.

[0018] In one embodiment, the water passage has a second communication cavity communicating with the first communication cavity, and the valve stem is provided with a sealing unit;

[0019] When the tapered surface abuts against the inner wall of the first communicating cavity, the sealing unit abuts against the inner wall of the second communicating cavity.

[0020] In one embodiment, the inner walls of the water inlet chamber and the water outlet chamber are both provided with protrusions, and a reset member is provided between each protrusion and the corresponding valve stem, and the reset member can drive the valve stem to move toward the connecting chamber.

[0021] In one embodiment, the fixing frame is provided with a limiting groove extending along its circumference, and the seat body is provided with a limiting block, and the limiting block can be inserted into the limiting groove.

[0026] A filter unit is detachably arranged on the connecting seat.

[0027] The technical solution of the present invention is to provide a connecting passage on the partition between the water inlet chamber and the water outlet chamber, so that when the filter unit is removed, the water inlet chamber and the water outlet chamber can be connected, thereby ensuring that the water supply waterway remains in a conductive state, thereby ensuring the normal use of the water purification device. In this embodiment, the valve core is movably arranged in the seat body, and the valve core has a blocking position and an open position. The valve core can be driven to switch between the blocking position and the open position by installing and removing the filter unit. The fixing bracket is used to install the seat body. By detachably mounting the seat body on the fixing bracket, it can reduce the difficulty of disassembling the seat body, thereby facilitating subsequent repair and maintenance. When the filter unit is installed on the connecting seat, the valve core is in the blocked position, and both the water inlet and outlet chambers are isolated from the connecting channel and connected to the connecting chamber. At this time, water flowing in from the water inlet chamber will flow through the connecting chamber, the filter unit in sequence, and finally out through the water outlet chamber. When the filter unit is removed, the valve core is in the open position, and both the water inlet and outlet chambers are connected to the connecting channel and isolated from the connecting chamber. At this time, water flowing in from the water inlet chamber will flow through the connecting channel and finally out through the water outlet chamber. In other words, when the filter unit is removed from the connecting seat, the water inlet and outlet chambers can still be connected through the connecting channel, thereby ensuring that the water supply waterway remains in a conductive state, ensuring the normal use of the water purification device. For users, when the water quality of the water source meets drinking requirements, the user can remove the filter unit to reduce the wear and tear of the filter unit and reduce the cost of use. At the same time, when the filter unit is blocked, the user can remove the filter unit to meet daily water supply needs. The connecting seat is applicable to technical fields such as water purification devices and water purification systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that meet both A and B.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0042] In a household water purification system, the water purification device is an important component of the water purification system for filtering and treating the water source. It has functions such as ultrafiltration, nanofiltration, and reverse osmosis filtration. The filter element of the filter unit can remove solid particles in the water and filter out harmful chemical components. The water purification device is mainly composed of a connecting seat and a filter unit installed on the connecting seat. However, after the filter unit of the existing water purification device is removed, the original water supply waterway will be cut off and cannot be used normally. Based on this, in actual use, if the water quality of the water source provided by the user meets the drinking requirements, but due to the functional limitations of the water purification device, it is still necessary to install a filter unit to filter the water source, which will increase the user's usage cost; and when the filter unit is blocked, this water supply waterway will also be cut off, and the user's water supply needs cannot be met.

[0043] The utility model provides a connecting seat and a water purification device, aiming to solve the technical problem of the existing water purification device in which the water supply channel is cut off after the filter unit is removed.

[0044] See also Figure 1 and Figure 3In one embodiment of the present invention, the connecting seat 100 is applied to a water purification device having a filter unit 200. The connecting seat 100 includes a fixing frame 1, a seat body 2, and a valve core 3. The seat body 2 is detachably mounted on the fixing frame 1. The seat body 2 is provided with a water inlet chamber 21, a water outlet chamber 22, and a partition portion 23 separating the water inlet chamber 21 and the water outlet chamber 22. The partition portion 23 is provided with a connecting passage 231. The valve core 3 is movably mounted in the seat body 2. The valve core 3 is provided with a connecting chamber 31, and the valve core 3 has a blocking position and an open position. When the valve core 3 is in the blocking position, both the water inlet chamber 21 and the water outlet chamber 22 are isolated from the connecting passage 231 and are connected to the connecting chamber 31. When the valve core 3 is in the open position, both the water inlet chamber 21 and the water outlet chamber 22 are connected to the connecting passage 231 and are isolated from the connecting chamber 31.

[0045] The technical solution of the present invention is to open a connecting channel 231 on the partition portion 23 between the water inlet chamber 21 and the water outlet chamber 22, so that the water inlet chamber 21 and the water outlet chamber 22 can be connected when the filter unit 200 is removed, thereby allowing the original water supply waterway to remain in a conductive state, thereby ensuring the normal use of the water purification device. In this embodiment, the valve core 3 is movably arranged in the seat body 2, and the valve core 3 has a blocking position and an open position, wherein the position switching of the valve core 3 is mainly achieved by installing and removing the filter unit 200, specifically: when the filter unit 200 is installed on the connecting seat, the valve core 3 switches to the blocking position; when the filter unit 200 is removed, the valve core 3 switches to the open position. The fixing bracket 1 is used to install the seat body 2. By detachably installing the seat body 2 on the fixing bracket 1, it can reduce the difficulty of disassembling the seat body 2, so as to facilitate subsequent repair and maintenance. Specifically, when the filter unit 200 is installed on the connecting seat 100, the valve core 3 is switched to the blocking position, and both the water inlet chamber 21 and the water outlet chamber 22 are isolated from the connecting passage 231 and are connected to the connecting chamber 31. At this time, water flowing in from the water inlet chamber 21 will flow through the connecting chamber 31 and the filter unit 200 in sequence, and finally flow out through the water outlet chamber 22. When the filter unit 200 is removed, the valve core 3 is switched to the open position, and both the water inlet chamber 21 and the water outlet chamber 22 are connected to the connecting passage 231 and are isolated from the connecting passage 31. At this time, water flowing in from the water inlet chamber 21 will flow through the connecting passage 231 and finally flow out through the water outlet chamber 22. In other words, when the filter unit 200 is removed from the connecting seat 100, the water inlet chamber 21 and the water outlet chamber 22 can still be connected through the connecting passage 231, thereby keeping the water supply path in a conductive state, ensuring the normal use of the water purification device. For the user, when the water quality of the water source meets the drinking requirements, the user can remove the filter unit 200 to reduce the wear and tear of the filter unit 200 and reduce the cost of use. At the same time, when the filter unit 200 is blocked, the user can remove the filter unit 200 so that the water flowing into the water inlet chamber 21 can flow through the connecting channel 231 and finally out of the water outlet chamber 22, meeting the user's daily water supply needs. The connector 100 is applicable to technical fields such as water purification devices and water purification systems.

[0046] It should be noted that when the filter unit 200 of this embodiment is installed to the connecting seat 100, that is, when one end of the filter unit 200 is inserted into the connecting cavity 31, the connecting cavity 31 will be divided into two chambers, one of which is connected to the water inlet chamber 21, and the other is connected to the water outlet chamber 22; when the filter unit 200 is installed on the connecting seat 100 and the filter unit 200 is not blocked, the water flowing into the water inlet chamber 21 will flow through the chamber connected to the water inlet chamber 21, the filter unit 200, and the chamber connected to the water outlet chamber 22 in sequence, and finally flow out through the water outlet chamber 22.

[0047] See also Figure 3 and Figure 4In one embodiment of the present utility model, the seat body 2 further includes an accommodating chamber 24 connected to the water inlet chamber 21 and the water outlet chamber 22, and the valve core 3 includes a valve body 32 movably arranged in the accommodating chamber 24, and a first column 33 and a second column 34 spaced apart from the valve body 32; when the valve core 3 is in a blocking position, the first column 33 and the second column 34 block the two openings of the communication channel 231; when the valve core 3 is in an open position, the first column 33 and the second column 34 open the two openings of the communication channel 231. In this embodiment, when the filter unit 200 is installed to the connecting seat 100, the filter unit 200 can push the valve core 3 to move upward to the blocking position. At this time, the first column 33 and the second column 34 block the two openings of the connecting channel 231 to separate the water inlet chamber 21 and the water outlet chamber 22 from the connecting channel 231; when the filter unit 200 is removed from the connecting seat 100, the valve core 3 will move downward to the open position under the action of its own gravity. At this time, the first column 33 and the second column 34 are separated from the opening of the connecting channel 231, opening the opening of the connecting channel 231 to connect the water inlet chamber 21 and the water outlet chamber 22 with the connecting channel 231. It should be noted that in this embodiment, regardless of whether the filter unit 200 is installed in the connection base 100, the first column 33 is always inserted into the water inlet chamber 21, and the second column 34 is always inserted into the water outlet chamber 22. The first column 33 and the second column 34 block or open the communication channel 231 by switching the positions of the first column 33 and the second column 34 so that the top surfaces of the first column 33 and the second column 34 are higher or lower than the top edge of the opening of the communication channel 231. In a specific embodiment, the valve body 32, the first column 33, and the second column 34 of the valve core 3 are integrally formed, that is, the valve core 3 is a one-piece molded component, which can simplify the structure of the connection base 100 and reduce the difficulty of assembling the connection base 100. Furthermore, the process of switching the valve core 3 to the blocked position is mainly driven by the filter unit 200 installed in the connection base 100. To ensure that the valve core 3 can switch from the blocked position to the open position, a corresponding spring can be provided between the valve core 3 and the base 2 to drive the valve core 3.

[0048] See also Figure 3 and Figure 4In one embodiment of the present invention, two first sealing members 331 are spaced apart on the first column 33 to abut against the inner wall of the water inlet chamber 21, and two second sealing members 341 are spaced apart on the second column 34 to abut against the inner wall of the water outlet chamber 22. When the valve core 3 is in the blocking position, the two first sealing members 331 are located on either side of the communication channel 231, and the two second sealing members 341 are located on either side of the communication channel 231. When the valve core 3 is in the open position, the two first sealing members 331 and the two second sealing members 341 are both located on the side of the communication channel 231 closest to the accommodating chamber 24. In this embodiment, both the first sealing members 331 and the second sealing members 341 are used to ensure the sealing effect of the connecting base 100. The first sealing member 331 and the second sealing member 341 have similar structures and functions. The following description will use the first sealing member 331 as an example. When the valve core 3 moves upward to the blocking position, the two first sealing members 331 are located on the upper and lower sides of the communication channel 231, respectively, which can better isolate the water inlet chamber 21 from the communication channel 231, thereby preventing water in the water inlet chamber 21 from flowing into the communication channel 231 when the connection base 100 is installed with the filter unit 200. When the valve core 3 moves downward to the open position, the two first sealing members 331 are located below the communication channel 231. At this time, water in the water inlet chamber 21 can flow into the communication channel 231 and out through the water outlet chamber 22. In addition, the first sealing member 331 can also isolate the water inlet chamber 21 from the accommodating chamber 24, thereby preventing water in the water inlet chamber 21 from flowing into the accommodating chamber 24, thereby preventing water seepage and leakage. The second sealing member 341 has similar functions to the first sealing member 331 and will not be described in detail here. In a specific embodiment, the first sealing member 331 and the second sealing member 341 are both sealing rings. An annular groove is formed on the first column 33 and the second column 34 , and each sealing ring is accommodated in the corresponding annular groove.

[0049] See also Figure 4In one embodiment of the present invention, the first column 33 and the second column 34 are both provided with a water passage 332, and each water passage 332 is provided with a valve stem 35; when the valve core 3 is in the blocking position, the filter unit 200 lifts each valve stem 35 to connect the water inlet chamber 21 and the connecting chamber 31, and connect the water outlet chamber 22 and the connecting chamber 31; when the valve core 3 is in the open position, the valve stem 35 blocks the water passage 332 to isolate the water inlet chamber 21 and the connecting chamber 31, and isolate the water outlet chamber 22 and the connecting chamber 31. In this embodiment, when the valve core 3 moves upward to the blocking position, the valve stem 35 is lifted by the filter unit 200. At this time, the water inlet chamber 21 is connected to one of the chambers of the connecting chamber 31, and the water outlet chamber 22 is connected to the other chamber of the connecting chamber 31. In this way, it can be ensured that the water flowing in from the water inlet chamber 21 can flow through one of the chambers of the connecting chamber 31, the filter unit 200, and the other chamber of the connecting chamber 31 in sequence, and finally flow out from the water outlet chamber 22; when the valve core 3 moves downward to the open position, the filter unit 200 has been removed from the connecting seat 100, that is, the valve stem 35 is no longer lifted by the filter unit 200. At this time, the valve stem 35 will move downward under the action of its own gravity to block the water passage 332, thereby preventing the water flowing in from the water inlet chamber 21 from flowing out of the water passage 332.

[0050] See also Figure 4 In one embodiment of the present invention, the water passage 332 has a first connecting cavity 3321, and the valve stem 35 is provided with a tapered surface 351. When the valve core 3 is in the open position, the tapered surface 351 abuts the inner wall of the first connecting cavity 3321. In this embodiment, when the valve core 3 moves downward to the open position, the valve stem 35 moves downward under its own weight until the tapered surface 351 abuts the inner wall of the first connecting cavity 3321. At this point, the valve stem 35 blocks the water passage 332. Providing the tapered surface 351 on the valve stem 35 that abuts the inner wall of the first connecting cavity 3321 not only enables the valve stem 35 to block the water passage 332, but also prevents the valve stem 35 from falling out of the water passage 332. In a specific embodiment, the first connecting cavity 3321 is provided at the lower end of the water passage 332, and the inner wall of the first connecting cavity 3321 is a conical surface. The valve stem 35 blocks the water passage 332 by means of two conical surfaces abutting against each other, which can better prevent the valve stem 35 from being flushed open.

[0051] See also Figure 4In one embodiment of the present invention, the water passage 332 has a second connecting cavity 3322 that communicates with the first connecting cavity 3321. The valve stem 35 is provided with a sealing unit 352. When the conical surface 351 abuts the inner wall of the first connecting cavity 3321, the sealing unit 352 abuts the inner wall of the second connecting cavity 3322. In this embodiment, the sealing unit 352 serves as a seal. That is, when the conical surface 351 of the valve stem 35 abuts the inner wall of the first connecting cavity 3321 of the water passage 332, the sealing unit 352 abuts the inner wall of the second connecting cavity 3322. This can better isolate the water passage 332 from the connecting cavity 31, thereby preventing water seepage and leakage. In a specific embodiment, the sealing unit 352 is a sealing ring, and the installation method of the sealing unit 352 is similar to that of the first sealing member 331 and the second sealing member 341, and will not be further described here.

[0052] In this embodiment, the water passage 332 also has a conducting cavity. When the sealing unit 352 is installed on the valve stem 35, the diameter of the sealing unit 352 at its largest point is slightly larger than the diameter of the second communicating cavity 3322. Thus, the sealing effect when the sealing unit 352 abuts against the inner wall of the second communicating cavity 3322 can be ensured; and the diameter of the sealing unit 352 at its largest point is smaller than the diameter of the conducting cavity, that is, when the filter unit 200 is installed to the connecting seat 100, the valve core 3 moves upward to the blocking position. At this time, the valve stem 35 is lifted up by the filter unit 200, and the sealing unit 352 is placed in the conducting cavity, so that the diameter of the sealing unit 352 at its largest point is smaller than the diameter of the conducting cavity, which can ensure the communication between the water inlet cavity 21 and the connecting cavity 31, as well as the communication between the water outlet cavity 22 and the connecting cavity 31, thereby ensuring the conduction of the water supply waterway.

[0053] See also Figure 3 and Figure 4 In one embodiment of the present invention, a protrusion 211 is provided on the inner walls of the water inlet chamber 21 and the water outlet chamber 22. A reset member 353 is provided between each protrusion 211 and the corresponding valve stem 35. The reset member 353 can drive the valve stem 35 toward the connecting chamber 31. In this embodiment, when the valve core 3 moves downward to the open position, the reset member 353 can apply a thrust to the valve stem 35, causing the valve stem 35 to move downward under the action of its own weight and the reset member 353 until the tapered surface 351 abuts the inner wall of the first connecting chamber 3321. By providing the reset member 353, an additional thrust is provided to drive the valve stem 35 downward, causing the tapered surface 351 of the valve stem 35 to abut the inner wall of the first connecting chamber 3321, thereby ensuring the sealing effect of the valve stem 35. In a specific embodiment, the protrusion 211 is an annular protrusion structure, and the reset member 353 is a spring. The structure and use of the spring are relatively mature, and the purchase cost of the spring is low, which can reduce the production cost of the connecting seat 100.

[0054] See also Figure 1 and Figure 2 In one embodiment of the present invention, the fixing frame 1 is provided with a limiting groove 11 extending along its circumference, and the base body 2 is provided with a limiting block 25, which can be inserted into the limiting groove 11. Specifically, when installing the base body 2 on the fixing frame 1, the base body 2 only needs to be placed on the fixing frame 1 and rotated so that the limiting block 25 is inserted into the limiting groove 11 to complete the installation of the base body 2. This can reduce the difficulty of installing the base body 2 and, in turn, reduce the difficulty of assembling the connecting base 100. In a specific embodiment, the fixing frame 1 is provided with two limiting grooves 11 extending along its circumference, and the base body 2 is provided with two limiting blocks 25, with the two limiting blocks 25 being arranged in a one-to-one correspondence with the two limiting grooves 11. In addition, the number of limiting grooves and limiting blocks can also be three, four, etc. In this embodiment, the mounting frame extends upward to form a first extension block, and the end of the first extension block away from the mounting frame extends along the circumference of the mounting frame to form a second extension block. The limiting groove is formed by the first extension block, the second extension block, and the mounting frame.

[0055] See also Figure 2 In one embodiment of the present invention, the fixing frame 1 is provided with a receiving groove 12, and the base 2 is received in the receiving groove 12. The inner wall of the receiving groove 12 is provided with a stopper 121, and the base 2 is provided with an arc-shaped block 26. When the limiting block 25 is inserted into the limiting groove 11, the arc-shaped block 26 can abut against the stopper 121. Specifically, when the limiting block 25 is inserted into the limiting groove 11, the stopper 121 is located directly above the arc-shaped block 26 and abuts against the arc-shaped block 26. Thus, the position of the base 2 can be locked in the vertical direction, ensuring the reliability of the base 2 when installed on the fixing frame 1. When the limiting block 25 is disengaged from the limiting groove 11, the stopper 121 and the arc-shaped block 26 are misaligned. At this time, the base 2 can be removed by lifting the base 2 upward. In a specific embodiment, there are two stoppers 121, and the base 2 is provided with two corresponding arc-shaped blocks 26. The two stoppers 121 are provided in a one-to-one correspondence with the two arc-shaped blocks 26. In addition, the number of the stop blocks and the arc blocks can also be three, four, etc.

[0056] The present invention also proposes a water purification device, which includes the above-mentioned connecting seat 100. The specific structure of the connecting seat 100 refers to the above-mentioned embodiment. Since the water purification device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0057] See also Figure 3The water purification device also includes a filter unit 200, which is detachably mounted on the connecting seat 100. Specifically, the filter unit 200 includes a bottle body 210 and a filter element 220 housed in the bottle body 210, wherein one end of the bottle body 210 passes through the fixing frame 1 and is inserted into the connecting cavity 31, and the filter element 220 divides the internal space of the bottle body 210 into a water inlet area and a water outlet area. When the filter unit 200 is installed on the connecting seat 100, the bottle body 210 is inserted into the connecting cavity 31, and the connecting cavity 31 is divided into two chambers. The water inlet chamber 21 and the water inlet area are both connected to one of the chambers, and the water outlet chamber 22 and the water outlet area are both connected to the other chamber. During water supply, water flowing into the water inlet chamber 21 flows through one of the chambers and the water inlet area of ​​the connecting cavity 31 in sequence, then passes through the filter element 220 and flows through the water outlet area and the other chamber of the connecting cavity 31 in sequence, and finally flows out from the water outlet chamber 22. In this embodiment, the inner side of the fixing frame 1 is provided with an L-shaped notch. Specifically, the notch is composed of a first groove extending along the axial direction of the fixing frame 1 and a second groove extending along the circumference of the fixing frame 1. The bottle body 210 is provided with a locking block. When installing the filter unit 200, the locking block of the bottle body 210 is inserted through the first groove and then rotated so that the locking block is positioned in the second groove. This completes the installation of the filter unit 200. Installing the filter unit 200 in this manner can reduce the difficulty of installing the filter unit 200 and, consequently, the difficulty of replacing the filter unit 200. In a specific embodiment, the first groove is tilted, allowing the user to install the filter unit 200 by simply inserting the filter unit 200 into the first groove and rotating it. During this process, the user only needs to rotate the filter unit 200, without having to lift it upward, thus reducing the difficulty of installing the filter unit 200.
