[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] Embodiment 1

[0039] See also Figure 1 and Figure 2 The utility model discloses a waterway plate 1. Specifically, a waterway is provided in the waterway plate 1. A waterway connector 11 and a locking assembly 12 are provided on the waterway plate 1. The waterway connector 11 is connected to the waterway, and the waterway connector 11 is provided with a water stop mechanism, which is used to open or close the waterway connector 11. In addition, the locking assembly 12 is used to lock and connect with an external connector 23.

[0040] On the basis of this structure, when the waterway plate 1 of the utility model is used, the waterway interface 22 on the filter element 2 can be plugged and connected with the waterway connector 11 on the waterway plate 1, and the waterway plate 1 is locked and connected with the connector 23 on the filter element 2 through the locking assembly 12. When the water purifier 3 is working, the water stop mechanism opens the waterway connector 11, so that the waterway in the waterway plate 1 can be mutually connected with the flow channel in the filter element 2, and the raw water can enter the filter element 2 through the waterway plate 1 for filtration, and the pure water and waste water obtained after filtration by the filter element 2 can be introduced into other waterways of the waterway plate 1 through the waterway connector 11.

[0041] When the filter element 2 is replaced, the water stopping mechanism can close the water channel joint 11; then when the filter element 2 is detached from the water channel plate 1, the water flow in the water channel of the water channel plate 1 is intercepted by the water stopping mechanism and will not flow out from the water channel joint 11, thereby avoiding water leakage during the connection or detachment of the water channel plate 1 with the filter element 2.

[0042] It should be noted that when the water purifier 3 is working, the water in the waterway will have a certain water pressure; when the filter element 2 is installed on the waterway plate 1, the filter element 2 may pop out under the action of the water pressure, causing the filter element 2 to separate from the waterway plate 1. Therefore, the present application sets a locking component 12 on the waterway plate 1. When the waterway plate 1 is connected with the filter element 2, the locking component 12 can lock the filter element 2 on the waterway plate 1, so as to prevent the filter element 2 from being affected by the water pressure of the waterway plate 1 and popping out away from the waterway plate 1 when the water purifier 3 is working, thereby ensuring the waterway conduction between the waterway plate 1 and the filter element 2.

[0043] In addition, when the filter element 2 is detached from the waterway plate 1, the locking assembly 12 needs to be unlocked first. After the locking function of the locking assembly 12 is lost, the filter element 2 may pop out instantly under the action of water pressure; this may cause injury to the operator or the filter element 2 to fall and be damaged. However, the present application sets a water stop mechanism at the waterway joint 11, and the water stop mechanism closes the waterway joint 11 before detaching the filter element 2 from the waterway plate 1. In this way, when the filter element 2 is separated from the waterway plate 1, the water flow in the waterway is intercepted by the water stop mechanism and water pressure cannot be applied to the filter element 2. The filter element 2 will not be ejected by the water pressure, which can eliminate the influence of water pressure on the filter element 2 during the core replacement process.

[0044] That is, the present application can lock the filter element 2 to the waterway plate 1 through the locking assembly 12, so as to prevent the water pressure in the waterway of the waterway plate 1 from causing the filter element 2 to pop open when the water purifier 3 is working. At the same time, the present application can prevent the water pressure in the waterway of the waterway plate 1 from instantly popping open the filter element 2 when the filter element 2 is detached from the waterway plate 1 by setting a water stop mechanism at the waterway joint 11; and after the filter element 2 is detached from the waterway plate 1, the water stop mechanism can prevent the waterway joint 11 on the waterway plate 1 from leaking.

[0045] Further, see Figure 3 and Figure 4 , the water stopping mechanism is a check valve 13.

[0046] The check valve 13 may be a swing check valve 13 or a lift check valve 13, which can automatically open and close the valve flap depending on the flow of the medium itself, thereby preventing the medium from flowing back.

[0047] Specifically, the check valve 13 can be installed at the end of the water channel in the water channel joint 11; when the water purifier 3 is working, the water flow is pressurized by the liquid pump and flows unidirectionally to the water channel joint 11 in the water channel of the water channel plate 1 to flow into the filter element 2, and the valve flap of the check valve 13 opens under the action of water pressure to make the water channel joint 11 conductive. When the water purifier 3 stops working and the filter element 2 is replaced, the water pressure in the water channel is not enough to open the valve flap, so the check valve 13 can intercept the water flow in the water channel, thereby closing the water channel joint 11, and the water channel joint 11 will not leak.

[0048] Since the working mode of the check valve 13 can be changed according to the water pressure in the water circuit, the check valve 13 can automatically open and close the water circuit connector 11 in response to the working condition of the water purifier 3, and automatically prevent the water circuit plate 1 from leaking when the filter element 2 is detached from the water circuit plate 1.

[0049] In addition, the water stop mechanism can also be a spring piece or a block, which can be arranged on the waterway in the waterway joint 11, or at the end of the waterway joint 11. When the water purifier 3 is working, the spring piece or the block moves away from the waterway in the radial direction of the waterway, so that the filter element 2 and the waterway plate 1 are connected; before replacing the filter element 2, the spring piece or the block can be extended into the waterway, thereby blocking the waterway joint 11, to prevent the water flow from overflowing from the waterway joint 11 after the filter element 2 is separated from the waterway plate 1.

[0050] Furthermore, the water channel plate 1 has a mounting surface 10, and the mounting surface 10 is used for mounting and matching with the filter element 2. The water channel connector 11 is arranged on the mounting surface 10.

[0051] Based on this structure, during assembly, the bottom of the filter element 2 is moved closer to the mounting surface 10 of the water channel plate 1 so that the water channel interface 22 at the bottom of the filter element 2 is plugged into the water channel connector 11 on the mounting surface 10 .

[0052] Thus, the water channel interface 22 at the bottom of the filter element 2 and the water channel connector 11 on the mounting surface 10 can be plugged into place in one step, which is convenient for disassembly and assembly; after the water channel plate 1 is connected with the filter element 2, the filter element 2 rests on the mounting surface 10 of the water channel plate 1, and is not prone to water leakage.

[0053] Furthermore, the water channel includes a first water channel and a second water channel, and a corresponding number of water channel connectors 11 are provided on the installation surface 10 , wherein the water outlet of the first water channel is connected to the water channel connector 11 , and the water inlet of the second water channel is connected to the water channel connector 11 .

[0054] Specifically, there is one first waterway, which is a raw water waterway, and two second waterways, which are a pure water waterway and a waste water waterway. The raw water waterway is used to guide the raw water into the filter element 2 for filtering and purifying, and the pure water waterway and the waste water waterway are used to guide the pure water and waste water produced by the filter element 2 to flow out respectively.

[0055] A water stopping mechanism is provided on the water channel joint 11 corresponding to the first water channel, so that when the filter element 2 is detached from the water channel plate 1, the water stopping mechanism can intercept the outflow of raw water in the raw water channel.

[0056] In addition, a water stopping mechanism may also be provided on the water channel joint 11 corresponding to the second water channel. Then, when the pure water or waste water in the second water channel does not completely flow out from the water outlet of the water channel plate 1, the water stopping mechanism can intercept the water flow in the pure water channel and the waste water channel from flowing back out of the water channel joint 11 during the process of separating the filter element 2 from the water channel plate 1.

[0057] Furthermore, at least one end of the waterway plate 1 is a connecting end 14 , and both the first waterway and the second waterway extend from the mounting surface 10 to the connecting end 14 .

[0058] Preferably, both ends of the waterway plate 1 are connection ends 14 , wherein the first waterway extends from the mounting surface 10 to one of the connection ends 14 , and the second waterway extends from the mounting surface 10 to the other connection end 14 .

[0059] Among them, the installation surface 10 is arranged on one side of the waterway plate 1 along the thickness direction, and the connection end 14 is arranged at the end of the waterway plate 1 along the length direction or the width direction; when both ends of the waterway plate 1 are connection ends 14, the two connection ends 14 are arranged opposite to each other.

[0060] Since the filter element 2 is arranged on one side of the mounting surface 10, when the waterway extends from the mounting surface 10 of the waterway plate 1 to the end of the waterway plate 1, it is convenient to connect the filter element 2 with the waterway connector 11; and since the first waterway and the second waterway extend from the mounting surface 10 toward two opposite connecting ends 14 respectively, there is no need to disassemble or damage other components on a large scale during maintenance, and the interfaces of the two connecting ends 14 and the waterway connector 11 on the mounting surface 10 can be directly inspected and repaired, making the maintenance process more convenient and quick.

[0061] Furthermore, the connection end 14 is provided with a first pipe and a second pipe, wherein the water outlet of the first pipe is connected to the water inlet of the first waterway, and the water inlet of the second pipe is connected to the water outlet of the second waterway.

[0062] Since the first water channel is a raw water channel, it can guide the raw water to flow into the filter element 2, so the first pipe can connect the waterway plate 1 and the faucet, and the raw water from the faucet can enter the waterway plate 1 through the first pipe, and then be guided by the waterway plate 1 into the filter element 2.

[0063] The second water circuit includes a pure water circuit and a waste water circuit. Two groups of second pipes are provided corresponding to the two water circuits. The pure water produced by the filter element 2 can flow out of the water purifier 3 through the pure water circuit and one group of second pipes and be supplied to the user. The waste water produced by the filter element 2 can be discharged from the water purifier 3 through the waste water circuit and another group of second pipes.

[0064] Thereby, the raw water can flow to the filter element 2 in one direction, and the pure water and waste water produced by the filter element 2 can flow out of the water purifier 3 in one direction, ensuring that the pure water waterway is not polluted.

[0065] Further, see Figure 3 and Figure 6 The locking assembly 12 is arranged on the mounting surface 10. Specifically, the locking assembly 12 includes a movable part 15 and a limit block 16 connected to the movable part 15, wherein the movable part 15 is movably connected to the waterway plate 1, and the limit block 16 is used to lock or unlock the filter element 2 during the movement of the movable part 15.

[0066] Based on this structure, see Figure 5 , a water channel interface 22 and a clamping rib are provided at the bottom of the filter element 2; during assembly, the filter element 2 is close to the installation surface 10 of the waterway plate 1 and the water channel interface 22 is connected to the waterway connector 11 on the installation surface 10, and then the movable part 15 moves relative to the waterway plate 1 to make the limit block 16 and the clamping rib of the filter element 2 limit connection, thereby locking the filter element 2 on the waterway plate 1. When replacing the filter element 2, the movable part 15 can be moved relative to the waterway plate 1 to make the limit block 16 away from the clamping rib of the filter element 2, thereby unlocking the filter element 2.

[0067] Among them, the movable part 15 can be a rotating sleeve, which is sleeved on the inner wall of the waterway plate 1, and the rotating sleeve can rotate relative to the waterway plate 1 under the action of external force. In addition, the rotating sleeve is provided with a plurality of limit blocks 16 spaced along the circumferential direction, and a limit groove is formed between two adjacent limit blocks 16. When the waterway interface 22 of the filter element 2 is inserted into the waterway connector 11 on the waterway plate 1, the bottom end of the filter element 2 is also inserted into the rotating sleeve, and when the rotating sleeve rotates, the clamping ribs on the outer periphery of the bottom end of the filter element 2 can be inserted into the limit groove, so that the filter element 2 is locked on the waterway plate 1; when unlocking, the rotating sleeve can be rotated in the opposite direction, so that the clamping ribs withdraw from the limit groove, thereby releasing the locking effect of the locking assembly 12, and the filter element 2 can be pulled out from the waterway plate 1.

[0068] In addition, the movable member 15 can also be a movable plate, which is slidably arranged on the mounting surface 10, and the bottom end of the filter element 2 can pass through the middle of the movable plate and conduct water with the water channel connector 11 on the mounting surface 10. Among them, the movable plate is provided with a plurality of limit blocks 16 spaced along the circumferential direction on the inner side of the bottom end of the filter element 2, and a limit groove is formed between two adjacent limit blocks 16. During assembly, the clamping ribs on the outer periphery of the bottom end of the filter element 2 are first passed through the limit grooves, and then the movable plate is slid to move the limit blocks 16 to one side of the clamping ribs, see Figure 7, whereby the limit block 16 can limit the withdrawal of the snap-in rib, so that the filter element 2 is locked on the waterway plate 1; when unlocking is to be performed, the movable plate can be slid in the opposite direction to move the limit groove to one side of the snap-in rib, and the snap-in rib can withdraw from the limit groove, thereby releasing the locking effect of the locking assembly 12, and the filter element 2 can be pulled out from the waterway plate 1.

[0069] Therefore, the locking component 12 can lock the filter element 2 and connect it to the water circuit plate 1, so as to prevent the filter element 2 from being affected by the water pressure of the water circuit plate 1 and popping out away from the water circuit plate 1 when the water purifier 3 is working, thereby ensuring the water circuit between the water circuit plate 1 and the filter element 2 is conductive; at the same time, the locking and unlocking switching of the locking component 12 is easy to operate, making the replacement of the filter element 2 more convenient.

[0070] Further, see Figure 1 The locking assembly 12 includes an elastic member 20 , and two ends of the elastic member 20 are respectively against the outer wall of the movable member 15 and the inner wall of the waterway plate 1 .

[0071] When the movable member 15 is a movable plate, the elastic member 20 provides an elastic force to the movable plate so that the movable plate slides to the unlocked position. Specifically, a first column 18 is provided on the outer wall of the movable member 15, and a second column 19 is correspondingly provided on the inner wall of the waterway plate 1. The elastic member 20 can be a spring, and the two ends of the spring are respectively sleeved on the first column 18 and the second column 19.

[0072] In addition, a pressing block 17 is provided at one end of the movable plate along the moving direction, and the pressing block 17 is used to drive the movable plate to slide to the locking position when pressed. When in use, the movable plate automatically slides to the unlocking position under the action of the elastic member 20, at which time the limit groove on the movable plate corresponds to the snap-fit ​​rib on the filter element 2, and when the filter element 2 is plugged into the waterway plate 1, the snap-fit ​​rib can be inserted under the movable plate through the limit groove; then force is applied to the pressing block 17 to move the movable plate to the locking position, at which time the limit block 16 is located above the snap-fit ​​rib, thereby locking the filter element 2 on the waterway plate 1.

[0073] When unlocking is required, the external force applied to the top pressure block 17 is removed, and the movable plate can automatically slide to the unlocking position under the action of the elastic member 20. Thus, the elastic member 20 can realize the automatic unlocking of the locking assembly 12, making the locking connection and unlocking and disassembly of the filter element 2 more convenient.

[0074] It should be noted that the elastic member 20 can also provide an elastic force to the movable member 15 so that the movable member 15 moves to the locking position to achieve automatic locking. For example, when the movable member 15 is a rotating sleeve, first apply force to the top pressure block 17 to rotate the rotating sleeve to the unlocking position, insert the filter element 2 and the waterway plate 1, and then remove the external force applied to the top pressure block 17. The elastic member 20 provides an elastic force to the rotating sleeve so that the rotating sleeve automatically rotates to the locking position. In the locking position, the limit groove and the clamping rib are plugged. In addition, the elastic member 20 can also be a rubber pad, a silicone pad, etc.

[0075] Embodiment 2

[0076] Different from the first embodiment, this embodiment discloses a water purifier 3, see Figure 8 and Fig. 9 The water purifier 3 includes a filter element 2 and the waterway plate 1 in the first embodiment. Figure 5 The bottom end of the filter element 2 is provided with a connection terminal 21, and the connection terminal 21 is provided with a water channel interface 22; specifically, the water channel interface 22 is plugged and matched with the water channel connector 11. The water stop mechanism on the water channel connector 11 is used to conduct the water channel connector 11 when the water channel connector 11 and the water channel interface 22 are plugged, and is used to close the water channel connector 11 after the water channel connector 11 and the water channel interface 22 are separated.

[0077] In addition, a connecting piece 23 is provided on the outer periphery of the connecting end 21 , and the connecting piece 23 is used to connect and lock the locking assembly 12 during the process of inserting the water channel interface 22 and the water channel connector 11 .

[0078] On this structural basis, the water purifier 3 includes a body 31 and a front panel 32. When using the water purifier 3 of the utility model, the waterway plate 1 can be connected to the body 31 of the water purifier 3. Specifically, the waterway plate 1 is connected to the body 31 of the water purifier 3 through a pipeline, so that the water purifier 3 can guide the waterway plate 1 to import or export water through a liquid pump. Then the filter element 2 is connected and locked to the waterway plate 1 through the connecting terminal 21, and then the front panel 32 covers the filter element 2; the front panel 32 of the water purifier 3 is provided with a water outlet, and the pure water filtered by the filter element 2 can flow out through the water outlet for users to drink.

[0079] When the water purifier 3 is working, the liquid pump guides the raw water to flow through the raw water channel in the water channel plate 1 and enters the filter element 2 through the water channel joint 11. The pure water and waste water produced after the filter element 2 filters and purifies the raw water enter the water channel plate 1 through the water channel interface 22, and are then respectively exported to the outside of the water purifier 3.

[0080] Among them, when the water purifier 3 is working, the water stopping mechanism on the water channel joint 11 opens the water channel joint 11, so that the water channel plate 1 and the filter element 2 are connected to each other. Since the water pressure in the water channel in the water channel plate 1 will push the filter element 2 away from the water channel plate 1, the water channel plate 1 locks the filter element 2 on the water channel plate 1 through the locking action of the locking component 12 and the connecting piece 23, eliminating the influence of the water pressure on the filter element 2.

[0081] Specifically, the filter element 2 is locked and connected to the waterway plate 1 through a connector at the bottom, and the gravity of the filter element 2 is concentrated at the bottom, making the locking assembly 12 more stable.

[0082] When replacing the filter element 2, the water stopping mechanism on the water channel joint 11 can close the water channel joint 11, so that during the separation of the filter element 2 and the water channel plate 1, the filter element 2 will not be affected by the water pressure and bounce open instantly; after the filter element 2 is separated from the water channel plate 1, the water channel interface 22 will not leak.

[0083] In addition, the connecting piece 23 on the outer periphery of the connecting end 21 can be a clamping rib, a connecting column, etc. After being connected to the locking assembly 12 on the waterway plate 1, the connecting piece 23 is limited on the waterway plate 1, so that the filter element 2 is locked on the waterway plate 1.

[0084] It should be noted that the specific structure and use process of the locking assembly 12, and the specific structure and use process of the water-stopping mechanism are described in detail in the first embodiment, and will not be elaborated in detail here.

[0085] The technical means disclosed in the utility model solution are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
