[0036] See also Figure 2-6 The utility model provides a filter element locking assembly, comprising a filter element 1, a waterway plate 2 and a locking plate 3. A connection portion 11 is provided at the bottom of the filter element 1, and a receiving groove 21 with an opening facing upward and a concave downward is provided on the waterway plate 2. In the assembled state, the connection portion 11 is plugged into the receiving groove 21 from top to bottom. The locking plate 3 is arranged on the waterway plate 2, and the locking plate 3 is annular in structure and surrounds the connection portion 11 in the assembled state. The waterway plate 2 can swing back and forth to a horizontal state or an inclined state, and the locking plate 3 swings back and forth with the waterway plate 2 and moves back and forth laterally relative to the waterway plate 2 under the action of a push-pull force to lock or unlock the connection portion 11.

[0037] The utility model sets a connection part 11 at the bottom of the filter element 1 to be plugged with the waterway plate 2, and installs the waterway plate 2 so that it can swing back and forth. In the assembled state, the waterway plate 2 drives the locking plate 3 to swing back and forth and drives the locking plate 3 to move back and forth laterally relative to the waterway plate 2 through push-pull force, so that the locking plate 3 locks or unlocks the connection part 11. Since the waterway plate 2 is set at the bottom of the filter element 1 to allow water to flow between the two, the overall force point of the filter element 1 is located at the bottom, that is, the bottom of the filter element 1 is concentratedly stressed. The 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, so that the filter element 1 is installed in the water purifier with stable and reliable characteristics. In addition, the locking structure of the filter element 1 of the utility model utilizes the swing of the waterway plate 2 to cooperate with the push-pull force to achieve the lateral reciprocating movement of the locking plate 3. The structure is simple and easy to install, which is convenient for replacing the filter element 1.

[0038] In the present invention, the filter element 1 includes a cylindrical filter element body 13, which is arranged vertically. The connecting portion 11 is a hexahedral structure and is arranged in the middle area of ​​the bottom of the filter element body 13. Three waterway interfaces are opened at the bottom of the connecting portion 11, which are used for raw water, pure water and concentrated water to flow through respectively. The arrangement of the three waterway interfaces is not specifically limited and is arranged according to the waterway connection method of the water purification equipment.

[0039] The middle area of ​​the waterway plate 2 is concave to form a receiving groove 21 with an opening facing upward, and a raw water inlet, a pure water outlet and a concentrated water outlet are provided in the receiving groove 21 to be connected to the three waterway interfaces at the bottom of the connecting part 11 in the assembled state. In order to improve the stability of the filter element installation structure, the raw water inlet, the pure water outlet and the concentrated water outlet are evenly dispersed in the receiving groove 21. A rotating shaft 24 is provided at the bottom of the waterway plate 2, and the rotating shaft 24 is transversely arranged in the middle area of ​​the bottom of the waterway plate 2, and the axial direction of the rotating shaft 24 is perpendicular to the direction of the transverse movement of the locking plate 3. The setting of the rotating shaft 24 is conducive to improving the sensitivity of the swing of the waterway plate 2, and the rotating shaft 24 is arranged in the middle area of ​​the bottom of the waterway plate 2, which improves the stability of the assembly structure.

[0040] The filter element locking assembly of the utility model also includes a mounting seat 4, and the waterway plate 2 can be mounted on the mounting seat 4 in a reciprocating swingable manner. One end of the locking plate 3 in the lateral moving direction extends outward to exceed the outer edge of the waterway plate 2 to form a pushing portion 31, and the mounting seat 4 is provided with a pushing block 41 corresponding to the pushing portion 31. The upper part of the pushing block 41 is inclined from top to bottom toward the pushing portion 31 to form an inclined surface 411, and the waterway plate 2 swings from an inclined state to a horizontal state relative to the mounting seat 4 so that the pushing block 41 drives the pushing portion 31 to slide downward along the inclined surface 411. When the waterway plate 2 is in an inclined state, the pushing portion 31 of the locking plate 3 is located above the pushing block 41. When the waterway plate 2 swings from an inclined state to a horizontal state, the locking plate 3 swings with the waterway plate 2 and the pushing portion 31 slides downward along the inclined surface 411, so as to push the locking plate 3 to move laterally relative to the waterway plate 2 to a locked state through the pushing block 41.

[0041] One end of the locking plate 3 in the lateral movement direction extends outward to exceed the outer edge of the waterway plate 2 to form a pulling portion 32. The pulling portion 32 extends in the same direction as the pushing portion 31. The pulling portion 32 is provided with a sliding groove 321 extending along the lateral movement. The mounting seat 4 is provided with a pulling block 42 corresponding to the sliding groove 321. The pulling block 42 is inclined from top to bottom toward the locking plate 3. The sliding groove 321 can be sleeved outside the pulling block 42 to be lateral and reciprocatingly movable. The waterway plate 2 swings from the horizontal state to the inclined state relative to the mounting seat 4 so that the pulling block 42 drives the pulling portion 32 to slide obliquely upward. The pulling block 42 always abuts against the groove wall of the sliding groove 321 on one side facing the locking plate 3. When the waterway plate 2 swings from the horizontal state to the inclined state, the locking plate 3 swings with the waterway plate 2 and the pulling portion 321 slides obliquely upward, so that the locking plate 3 is pulled by the pulling block 42 to move in the opposite direction to the waterway plate 2 to the unlocked state.

[0042] Specifically, the pull block 42 includes a vertically arranged limit pin 421 and an inclined block 422, wherein the inclined block 422 is arranged on the side of the limit pin 421 facing the locking plate 3 and is inclined from top to bottom. The limit pin 421 limits the sliding groove 321, and the inclined block 422 abuts against the groove wall of the sliding groove 321 to pull the locking plate 3 to move horizontally to the unlocked state.

[0043] In the present invention, the pushing part 31 is arranged in the middle of the locking plate 3, and two pulling parts 32 are provided. The two pulling parts 32 are symmetrically arranged on both sides of the pushing part 31, and the number of the pulling blocks 42 is equal to the number of the pulling parts 32 and the positions correspond one to one. Thus, the pushing force is located in the middle, and the two pulling forces are evenly distributed on both sides, so that the locking plate 3 can be evenly subjected to the pushing force and the pulling force to maintain the accuracy of the lateral movement and the reverse direction.

[0044] On this basis, two side plates 22 are arranged in parallel on the waterway plate 2, and the two side plates 22 are arranged along the lateral movement direction of the locking plate 3, and the two side plates 22 extend upward from the top surface of the waterway plate 2 to form a guide space for the lateral movement of the locking plate 3 between the two side plates 22, and the locking plate 3 is arranged in the guide space. The utility model forms a guide space between the two side plates 22 to limit the movement direction of the locking plate 3, so as to ensure the smooth locking or unlocking of the filter element 1.

[0045] Furthermore, one end of the locking plate 3 in the lateral movement direction extends outward to form a guide portion 33, and the waterway plate 2 is provided with a guide slide 23 corresponding to the guide portion 33, and the guide portion 33 is provided on the guide slide 23. The coordinated arrangement of the guide slide 23 and the guide portion 33 further improves the accuracy of the lateral movement of the locking plate 3 relative to the waterway plate 2.

[0046] In addition, the waterway plate 2 of the utility model is fixed to the bottom of the filter element seat 5, the locking plate 3 is located between the filter element seat 5 and the waterway plate 2, and the filter element seat 5 is provided with a guide groove 51 adapted to the connection portion 11, and the guide groove 51 is arranged correspondingly to the receiving groove 21 up and down. Among them, the center of gravity of the filter element seat 5, the waterway plate 2 and the filter element 1 are in a straight line to improve the stability of the installation of the filter element 1. The guide groove 51 is provided in the middle area of ​​the filter element seat 5 and corresponds to the receiving groove 21 up and down. Therefore, during installation, the connection portion 11 passes through the locking plate 3 from top to bottom through the guide groove 51 and is inserted into the receiving groove 21.

[0047] On the one hand, the filter element seat 5 is arranged above the locking plate 3, and the filter element seat 5 cooperates with the waterway plate 2 to limit the locking plate 3 in the vertical direction, so as to prevent the locking plate 3 from being separated from the waterway plate 2 upward. On the other hand, the connection part 11 is connected to the waterway plate 2 through the guide groove 51 of the filter element seat 5, which can improve the accuracy and stability of the connection between the connection part 11 and the receiving groove 21. Therefore, the arrangement of the filter element seat 5 can improve the stability of the installation of the filter element 1.

[0048] The filter element seat 5 is an upwardly open semi-enclosed structure and is adapted to the lower part of the filter element 1. The lower side wall of the filter element 1 is convexly provided with a clamping protrusion 14, and the filter element seat 5 is provided with a corresponding clamping groove 53 corresponding to the clamping protrusion 14. Specifically, the semi-enclosed structure of the filter element seat 5 is an upwardly open cylindrical structure to enclose the lower part of the filter element body 13, thereby improving the stability of the connection between the filter element 1 and the waterway plate 2. The clamping protrusion 14 is provided at the lower part of the filter element body 13, and the clamping structure of the clamping protrusion 14 and the clamping groove 53 can prevent the filter element 1 from rotating relative to the filter element seat 5, thereby further improving the stability of the installation of the filter element 1.

[0049] On the basis of the above structure, at least one stopper 12 is convexly provided on the side wall of the connection part 11 extending in the lateral moving direction of the locking plate 3, the inner wall of the locking plate 3 is concave to form an unlocking channel 34 for the stopper 12 to pass through, and the groove wall of the guide groove 51 is concave to form a guide channel 52 for the stopper 12 to pass through, and the number of the unlocking channels 34 and the number of the guide channels 52 are equal to the number of the stopper 12. In the assembled state, the guide channel 52 is arranged opposite to the corresponding stopper 12 in the vertical direction, and the locking plate 3 moves back and forth in the horizontal direction relative to the waterway plate 2 so that the corresponding unlocking channel 34 and the stopper 12 are arranged opposite to each other in the vertical direction or staggered in the vertical direction, thereby unlocking or locking the connection part 11.

[0050] Therefore, see Figure 7 and Figure 8 The principle of locking or unlocking the filter element 1 of the utility model is as follows:

[0051] In the unassembled state, the waterway plate 2 swings to an inclined state, that is, the end of the waterway plate 2 close to the push block 41 is higher. In this state, the filter element seat 5 and the locking plate 3 are in a synchronously inclined state with the waterway plate 2, the pushing portion 31 of the locking plate 3 is located above the push block 41, the inclined block 422 abuts against the groove wall of the sliding groove 321, and the guide channel 52 and the corresponding unlocking channel 34 are arranged opposite to each other up and down.

[0052] When installing the filter element 1 and locking it, the filter element 1 is passed through the guide groove 51 and the locking plate 3 in sequence at the same inclination angle, and the limiter 12 is passed through the corresponding guide channel 52 and the unlocking channel 34 in sequence, so that the connection part 11 is inserted into the receiving groove 21. The filter element 1 is swung to use the deadweight of the filter element 1 to press the waterway plate 2 and the filter element seat 5 to swing synchronously to a horizontal state, the locking plate 3 swings with the waterway plate 2 and the pusher 31 slides downward along the inclined surface 411, so that the locking plate 3 is pushed by the push block 41 to move horizontally relative to the waterway plate 2 to the unlocking channel 34 and the corresponding limiter 12 and the guide channel 52 are staggered up and down, and the inner wall of the convex part of the locking plate 3 blocks the upper part of the corresponding limiter 12 to prevent the limiter 12 from disengaging upward from the guide channel 52, thereby locking the connection part 11 and completing the locking of the filter element 1. Note that the inclined block 422 always abuts against the groove wall of the sliding groove 321.

[0053] When unlocking and removing the filter element 1, the filter element 1 is swung in the opposite direction to use the weight of the filter element 1 to press the waterway plate 2 and the filter element seat 5 to swing in the opposite direction synchronously to an inclined state. The locking plate 3 swings with the waterway plate 2 and the pulling part 321 slides upward at an angle, so that the locking plate 3 is pulled by the pulling block 42 to move horizontally in the opposite direction relative to the waterway plate 2 until the unlocking channel 34 and the corresponding limit member 12 and guide channel 52 are arranged opposite to each other up and down. The limit member 12 can be disengaged upward through the corresponding unlocking channel 34 and guide channel 52, thereby unlocking the connecting part 11 and completing the unlocking of the filter element 1.
