[0046] Embodiment 1

[0047] Refer to Figure 2 , the present invention discloses a filter element installation structure, which includes a filter element 1, a water circuit board assembly, a locking member and a mounting seat 5. Specifically, a connecting part 11 is provided at the bottom of the filter element 1; refer to Figure 4 , the water circuit board assembly includes a water circuit board 2 and a water guiding pipe 3. Among them, the water circuit board 2 has a first end 21 and a second end 22 facing away from each other. Refer to Figure 5 , a receiving groove 23 is recessed at the first end 21, and the connecting part 11 is inserted into the receiving groove 23 from top to bottom in the assembled state; the water guiding pipe 3 is arranged at the second end 22, and the water guiding pipe 3 is in water communication with the water circuit board 2.

[0048] Refer toFigure 4 and Figure 5 A locking member is movably arranged at the first end 21. In the assembled state, the locking member is used to move close to the connecting portion 11 so that the locking member is in a locked state of locking the connecting portion 11, or the locking member is used to move away from the connecting portion 11 so that the locking member is in an unlocked state of unlocking the connecting portion 11. It should be noted that the water conduit 3 is rotatably connected to the mounting base 5, and the water conduit 3 is used to drive the water circuit board 2 and the locking member to swing relative to the mounting base 5 during rotation. Among them, the locking member is used to switch between the locked state and the unlocked state during the swinging process.

[0049] On the basis of this structure, when using the filter element mounting structure of the present utility model, the connecting portion 11 at the bottom of the filter element 1 can be inserted into the receiving groove 23 of the water circuit board 2 from top to bottom in the unlocked state of the locking member, and then the water conduit 3 is rotated. The water conduit 3 drives the water circuit board 2 and the locking member to swing from an inclined position to a horizontal position relative to the mounting base 5, and the locking member moves close to the connecting portion 11 of the filter element 1 during the swinging process, so as to switch from the unlocked state to the locked state; when the filter element 1 needs to be replaced after being used for a period of time, the water conduit 3 can be rotated. The water conduit 3 drives the water circuit board 2 and the locking member to swing from a horizontal position to an inclined position relative to the mounting base 5, and the locking member moves away from the connecting portion 11 of the filter element 1 during the swinging process, so as to switch from the locked state to the unlocked state. At this time, the old filter element 1 can be taken out and a new filter element 1 can be inserted into the receiving groove 23.

[0050] Among them, the water conduit 3 can connect the water circuit between the body of the water purifier and the filter element 1, and at the same time can be used as the rotating shaft when the water circuit board 2 and the locking member swing. When the water conduit 3 is used as the rotating shaft, a dynamic sealing structure is formed between it and the mounting base 5 during rotation, which can not only effectively prevent water leakage, but also avoid the additional setting of a separate rotating shaft structure, realizing the integrated design of the structure. When rotating the water conduit 3, the water conduit 3 can be driven to rotate by a motor to switch the locked state and the unlocked state of the locking member, and then the filter element 1 can be replaced manually.

[0051] Preferably, in the present application, the filter element 1 is locked and unlocked by manually swinging it. Since the receiving groove 23 is adaptively arranged with the connecting portion 11, when the connecting portion 11 of the filter element 1 is inserted into the receiving groove 23 of the water circuit board 2, the filter element 1 and the water circuit board 2 are limited in the swinging direction with respect to each other. Therefore, by swinging the filter element 1, the filter element 1 can drive the water circuit board assembly and the locking member to swing relative to the mounting base 5. Specifically, with the rotation axis of the water guide pipe 3 as the center, the part of the water circuit board 2 on one side of the rotation axis is the first side, and the part of the water circuit board 2 on the other side of the rotation axis is the second side. The height of the first side of the water circuit board 2 in the inclined position is less than the height of the second side; when it is necessary to lock the filter element 1 in the assembled state, swing the filter element 1 so that the filter element 1 presses down the second side of the water circuit board 2, and the water circuit board 2 drives the locking plate 4 to swing to the horizontal position. Similarly, when it is necessary to unlock the filter element 1, swing the filter element 1 so that the filter element 1 presses down the first side of the water circuit board 2, and the water circuit board 2 drives the locking plate 4 to swing to the inclined position. Thus, the locking state and unlocking state of the locking member can be flexibly switched by manually swinging the filter element 1.

[0052] It should be noted that the moving direction of the locking member is perpendicular to the insertion direction of the connecting portion 11. When the locking member locks the connecting portion 11, the connecting portion 11 cannot withdraw along the insertion direction, thereby ensuring the connection between the filter element 1 and the water circuit board assembly.

[0053] Thus, the water circuit board assembly of the present application is rotatably connected to the mounting base 5 through the water guide pipe 3. In the assembled state, the water circuit board assembly can be driven to swing relative to the mounting base 5 by swinging the filter element 1. At the same time, the water circuit board assembly drives the locking member to swing, and the locking action and unlocking action of the locking member are completed by using the swing of the locking member. That is, the locking and unlocking of the filter element 1 can be realized by swinging the filter element 1. The structure is simple, the operation is convenient, and the filter element can be replaced quickly.

[0054] In addition, when the water purifier is working, the water in the water circuit of the water circuit board 2 will have a certain water pressure; when the filter element 1 is directly inserted into the water circuit board 2, the filter element 1 may pop out under the action of the water pressure, resulting in the separation of the filter element 1 from the water circuit board 2. However, the water circuit board assembly of the present application locks the filter element 1 in the receiving groove 23 through the locking member. Then, during the working process of the water purifier, the water pressure in the water circuit of the water circuit board 2 will not drive the filter element 1 away from the water circuit board 2, ensuring the conduction of the water circuit between the water circuit board 2 and the filter element 1; and it is not easy for the filter element 1 and the water circuit board 2 to loosen, preventing water leakage.

[0055] In addition, the overall stress point of the filter element 1 is located at the bottom, that is, the bottom of the filter element 1 is stressed concentratedly. And the present utility model installs the locking structure of the filter element 1 at the bottom of the filter element 1, which can improve the stability of the locking structure, making the filter element 1 have the characteristics of stable and reliable installation in the water purifier. Among them, the water guide pipe 3 has high mechanical strength and stability as a rotating shaft, which can ensure the reliability of the filter element installation structure.

[0056] Further, referring to Figure 2 , a pressing portion 51 is provided on the mounting base 5. Referring to Figure 5 , one end portion of the locking member extends outward relative to the water circuit board 2 to have a pushing portion 44. Wherein, the locking member is used to approach or move away from the pressing portion 51 during the swinging process, and the pushing portion 44 is used to be pressed by the pressing portion 51 and drive the locking member to move transversely relative to the water circuit board 2 after the locking member moves closer to the pressing portion 51.

[0057] In addition, the locking member and the water circuit board 2 are elastically connected by an elastic member 41, and the elastic member 41 is arranged along the transverse movement direction of the locking member. Wherein, the locking member is used to compress the elastic member 41 and move closer to the connecting portion 11 when being pressed by the pressing portion 51; the elastic member 41 is used to provide an elastic force to drive the locking member to move reciprocally transversely relative to the water circuit board 2 after the locking member moves away from the pressing portion 51, so as to switch between the locked state and the unlocked state.

[0058] On the basis of this structure, when replacing the filter element, the filter element 1 on the mounting base 5 can be swung from the vertical position to the inclined position, and at the same time the water circuit board assembly is rotated from the horizontal position to the inclined position. At this time, the pushing portion 44 moves away from the pressing portion 51, and the locking member automatically moves away from the connecting portion 11 under the action of the elastic member 41, and the locking member switches to the unlocked state. Then the old filter element 1 can be pulled out, and the connecting portion 11 of the new filter element 1 is inserted into the receiving groove 23, and then the filter element 1 is swung from the inclined position to the vertical position, and at the same time the water circuit board assembly drives the locking member to rotate to the horizontal position. During this process, the pushing portion 44 gradually approaches the pressing portion 51 and is pressed by the pressing portion 51. The pushing portion 44 compresses the elastic member 41 and gradually approaches the connecting portion 11, so as to switch to the locked state to lock the connecting portion 11 in the receiving groove 23.

[0059] Wherein, the elastic member 41 is a spring or a silica gel pad, etc., and both ends of the elastic member 41 respectively abut between the locking member and the water circuit board 2. The locking member moves transversely relative to the water circuit board 2 both when being pressed by the pressing portion 51 and when being ejected by the elastic member 41. As the filter element 1 swings reciprocally, the locking member moves transversely relative to the water circuit board 2 reciprocally, so as to repeatedly switch between the locked state and the unlocked state.

[0060] Thus, by manually swinging the filter element 1 to drive the locking member to approach and move away from the pressing portion 51, the switching between the locked state and the unlocked state of the filter element 1 is realized, and the replacement of the filter element 1 can be completed in a short time; the operation process is simplified, and the firm installation of the filter element 1 and the sealing performance of the water circuit system are ensured.

[0061] Further, referring to Figure 2, on opposite sides of the connecting portion 11, at least two limiting members 12 are convexly provided, and the at least two limiting members 12 are arranged at intervals along the lateral movement direction of the locking member. Refer to Figure 4 , the locking member includes a locking plate 4, and the pushing portion 44 is arranged at one end of the locking plate 4 along the lateral movement direction. The locking plate 4 has an annular structure and surrounds the periphery of the receiving groove 23. Specifically, the annular inner wall of the locking plate 4 is concave and convex towards the receiving groove 23 so that the concave portions form unlocking channels 42 and the convex portions form locking portions 43, and the number of unlocking channels 42 and the number of locking portions 43 are both equal to the number of limiting members 12 and are in one-to-one correspondence in position; among them, the unlocking channels 42 are adapted to the corresponding limiting members 12. Refer to Figure 6 and Figure 7 , the locking plate 4 reciprocates laterally relative to the waterway plate 2 so that the locking portion 43 or the unlocking channel 42 moves above the corresponding limiting member 12, thereby locking or unlocking the connecting portion 11.

[0062] On this structural basis, refer to Figure 6 , in the assembled state and when the locking plate 4 is in the unlocked state, the unlocking channels 42 on the locking plate 4 are arranged opposite to the limiting members 12 on the filter element 1, and the unlocking channels 42 are located above the limiting members 12. The limiting members 12 can pass through the unlocking channels 42 to realize the detachment of the filter element 1 from the waterway plate assembly. When locking the filter element 1 in the assembled state, when the filter element 1 is swung from an inclined position to a vertical position, the waterway plate assembly and the locking plate 4 swing synchronously to a horizontal position. When the pushing portion 44 of the locking plate 4 and the pressing portion 51 on the mounting seat 5 press against each other, refer to Figure 7 , the locking plate 4 moves laterally relative to the waterway plate 2 so that the locking portion 43 moves above the corresponding limiting member 12, thereby restricting the vertical movement of the filter element 1.

[0063] Thus, when installing or disassembling the filter element 1, only by reciprocally swinging the filter element 1 in the assembled state can the relative positional relationship between the limiting member 12 and the locking portion 43 and the unlocking channel 42 be changed, and the locking or unlocking of the filter element 1 can be automatically realized by means of the position change of the locking portion 43 and the unlocking channel 42.

[0064] Among them, the limiting member 12 can be a limiting rib or a clamping block. There is a gap between the limiting member 12 and the top end of the connecting portion 11, so that in the assembled state, the locking plate 4 can be located between the limiting member 12 and the top end of the connecting portion 11, so that the locking plate 4 can move the locking portion 43 or the unlocking channel 42 above the limiting member 12 during the lateral movement process.

[0065] In addition, a clamping groove can be provided on the lateral side of the limiting member 12, and a clamping hook can be protrudingly provided on the lateral side of the locking portion 43. During assembly, first insert the limiting member 12 into the unlocking channel 42, and then the locking plate 4 moves laterally under the pressing of the pressing portion 51, so that the clamping hook on the locking portion 43 is inserted into the clamping groove on the limiting member 12, thereby achieving locking; when the locking plate 4 moves laterally under the action of the elastic member 41, the clamping hook on the locking portion 43 exits the clamping groove on the limiting member 12, thereby achieving unlocking.

[0066] Further, referring to Figure 8 , the pressing portion 51 is provided with a guiding inclined surface 52 that is inclined downward from top to bottom towards the pushing portion 44, so that the pushing portion 44 slides downward along the guiding inclined surface 52 and moves laterally towards the water circuit board 2.

[0067] On the basis of this structure, when the filter element 1 needs to be locked in the assembled state, swing the filter element 1 to press the second side of the water circuit board 2 downward. The water circuit board 2 drives the locking plate 4 to swing from the inclined position to the horizontal position. During this process, the pushing portion 44 of the locking plate 4 slides downward along the guiding inclined surface 52, and at the same time, the pushing portion 44 pushes the locking plate 4 to move laterally towards the water circuit board 2, so that the locking portion 43 of the locking plate 4 moves above the corresponding limiting member 12 to block the corresponding limiting member 12 from disengaging upward through the locking portion 43.

[0068] Thus, the pressing portion 51 can guide the lateral movement of the locking plate 4 through the guiding inclined surface 52, ensure the stability of the pushing portion 44 during the operation process, ensure that the pushing portion 44 is smoothly acted on by the pressing portion 51, and move relative to the water circuit board 2. In addition, the setting of the pressing portion 51 makes the filter element replacement operation more intuitive and convenient; when the user installs or replaces the filter element 1, only need to operate according to the set action sequence, and the pushing portion 44 will move as expected under the action of the pressing portion 51, thereby completing the steps of locking or unlocking the filter element 1.

[0069] Further, referring to Figure 8 and Figure 9 , the pushing portion 44 is provided with a guiding groove 45 extending along the lateral movement direction, the mounting seat 5 is provided with a vertically arranged guiding pin 53, and the guiding pin 53 is inserted into the guiding groove 45, and the guiding groove 45 can move laterally relative to the guiding pin 53.

[0070] On the basis of this structure, during the process of the water circuit board assembly swinging from the inclined position to the horizontal position, the guiding groove 45 is inserted into the guiding pin 53 from top to bottom; when the locking plate 4 is pressed and moved by the pressing portion 51, the guiding groove 45 can move laterally relative to the guiding pin 53.

[0071] Among them, the guide groove 45 and the guide pin 53 are inserted into or disengaged during the swinging process of the waterway plate assembly, so that the waterway plate assembly can be accurately guided and fixed in the correct position during the swinging process, ensuring that the position of the locking plate 4 corresponds to the top pressure part 51; and in the process of the locking plate 4 being pressed by the top pressure part 51 and moving, the locking plate 4 is guided to move horizontally, ensuring the smooth movement of the locking plate 4.

[0072] Further, see Figure 3 , a filter element seat 6 is installed above the locking plate 4, and the filter element seat 6 is provided with a guide groove adapted to the connection part 11, and the groove wall of the guide groove is arranged concave-convex toward the connection part 11 so that the concave part forms a guide channel 61 adapted to the limiter 12, and two adjacent convex parts of the guide channel 61 form a guide part. Among them, the number of the guide channels 61 is equal to the number of the limiters 12 and the positions correspond one to one.

[0073] On the basis of this structure, when the locking plate 4 is in the unlocked state, the unlocking channel 42 on the locking plate 4 is arranged opposite to the guide channel 61 on the filter element seat 6; when the filter element 1 and the waterway plate 2 are assembled, the connection part 11 at the bottom of the filter element 1 is first inserted into the guide groove and then inserted into the receiving groove 23, wherein the limiter 12 on the connection part 11 is guided into the unlocking channel 42 via the guide channel 61. When locking the filter element 1, the swing filter element 1 drives the waterway plate 2 to rotate to a horizontal position, and the locking plate 4 is pressed by the pressing part 51 and moves laterally relative to the filter element seat 6 and the waterway plate 2, so that the unlocking channel 42 on the locking plate 4 and the guide channel 61 on the filter element seat 6 are staggered, and the connection part 11 of the filter element 1 cannot be separated from the receiving groove 23.

[0074] Among them, the guide groove ensures that the connection part 11 can be accurately inserted into the filter element seat 6, the guide channel 61 can ensure that the connection part 11 finds the correct position during the insertion process, and the guide part provides a guiding force to help the connection part 11 to be smoothly inserted and fixed. In addition, the setting of the guide groove and the guide channel 61 ensures that the connection part 11 will not accidentally move or deviate from the position, thereby improving the stability of the overall structure. During the use of the filter element 1, this stability is crucial to ensure a good connection between the waterway plate 2 and the filter element 1.

Correspondingly, three water guide holes 24 are provided on the water circuit board 2, and one ends of the three water guide holes 24 are respectively connected to three water circuit interfaces at the bottom of the filter element 1. The three water guide holes 24 are respectively a first water guide hole 25, a second water guide hole 26 and a third water guide hole 27.

[0080] Among them, the first flow channel 31 communicates with the first water guide hole 25, the first flow channel section communicates with the second water guide hole 26, and the second flow channel section communicates with the third water guide hole 27. In addition, both ends of the water guide pipe 3 are respectively connected to external pipes. The water purifier can introduce raw water into the corresponding waterway interface on the filter element 1 through the external pipe, the first flow channel 31, and the first water guide hole 25. The pure water and wastewater generated after the filtration of the filter element 1 are respectively led out to the external pipe through the second water guide hole 26 and the first flow channel section, and the third water guide hole 27 and the second flow channel section.

[0081] In another embodiment, referring to Figure 11 , the water guide pipe 3 may further include a first pipe section 33 and a second pipe section 34 that are arranged at intervals along the axial direction of the water guide pipe 3. Referring to Figure 12 , and an inner pipe section is further provided in the second pipe section 34.

Among them, the first flow channel 31 communicates with the first water guide hole 25, the inner flow channel communicates with the second water guide hole 26, and the second flow channel 32 communicates with the third water guide hole 27.

[0082] Through the above two flow channel setting methods, it is possible to achieve one-way water inlet and two-way water outlet for the water guide pipe 3. This setting allows for effective diversion and flow control of water inside the water guide pipe 3. Through the settings of the first flow channel 31 and the second flow channel 32, it can be ensured that the raw water and pure water flow along the designed path when flowing through the filter element 1, ensuring the balanced flow and effective filtration of water in the entire system.

Specifically, both ends of the water guide pipe 3 are respectively rotatably sleeved on one end of the adapter 35, and the connection part between the two is sealed. Among them, a protruding block may also be provided on the adapter 35, and a sliding groove is provided on the water guide pipe 3; when the water guide pipe 3 rotates relative to the adapter 35, the sliding groove slides relative to the protruding block, and by restricting the width of the sliding groove in the axial direction of the water guide pipe 3, the rotation angle of the water guide pipe 3 is restricted, thereby restricting the swing angle of the filter element 1.

[0085] Among them, the adapter 35 is a transfer pipe, and the pipe interface 351 is used to connect to an external pipe. The adapter 35 can connect the external pipe and the water guide pipe 3; and the adapter 35 can effectively prevent water leakage or loosening of the pipe interface 351, thereby improving the overall stability and long-term reliability of the system. Users can flexibly choose to introduce or export raw water or treated water into or out of a specific flow channel according to specific water treatment requirements and system configurations.

[0086] In addition, each adapter 35 is directly connected to one end of the water guide pipe 3, which simplifies the installation and maintenance process of the filter element 1 assembly and reduces the possible assembly errors during the installation process.
