[0044] See also Figure 1-13 The utility model provides a filter element assembly, which includes a filter element 1, a waterway plate 2, a locking plate 3 and a body 4. Among them, a connecting portion 11 is provided at the bottom of the filter element 1, and a handle 12 is rotatably installed on the top of the filter element 1. The center of gravity offset of the handle 12 has a tendency to drive the handle 12 to rotate to be horizontally stored at the top of the filter element 1. The waterway plate 2 is provided with a receiving groove 21 with an opening facing upward and a concave downward. In the assembled state, the connecting portion is inserted into the receiving groove 21 from top to bottom, and the waterway plate 2 can swing back and forth to a horizontal state or an inclined state. The locking plate 3 is arranged on the waterway plate 2 and can move back and forth laterally relative to the waterway plate 2. The locking plate 3 is an annular structure and surrounds the connecting portion 11 in the assembled state. The body 4 is provided with an installation cavity 41 adapted to the filter element 1, and the waterway plate 2 can be swingably installed on the body 4 and is located at the bottom of the installation cavity 41. In the assembled state and the waterway plate 2 swings to the horizontal state, the locking plate 3 moves horizontally relative to the waterway plate 2 to the locking connection part 11, and the handle 12 rotates toward the body 4 to be horizontally stored on the top of the filter element 1 and locked to the body 4. In the assembled state and the waterway plate 2 swings to the inclined state, the locking plate 3 moves horizontally relative to the waterway plate 2 to the unlocking connection part 11, and the handle 12 rotates to unlock the body 4.

[0045] The filter element assembly of the utility model is provided with a connection part 11 at the bottom of the filter element 1 to be plugged with the waterway plate 2, and the waterway plate 2 is swingably installed on the machine body 4, and in the assembled state, the waterway plate 2 swings back and forth relative to the machine body 4 to make the locking plate 3 move back and forth laterally relative to the waterway plate 2, thereby realizing that the locking plate 3 locks or unlocks the connection part 11; by providing a handle 12 at the top of the filter element 1, and the center of gravity of the handle 12 is offset so that when the filter element 1 is installed in the installation cavity 41, the handle 12 can be rotated to a horizontal state by its own weight and locked with the machine body 4, thereby realizing the locking of the top of the filter element 1 with the machine body 4 through the handle 12. Therefore, the utility model ensures that the filter element 1 is stably installed in the water purifier by double locking the top and bottom of the filter element 1. In addition, the filter element locking structure of the utility model is simple, easy to operate, and convenient to replace the filter element 1.

[0046] See also Figure 8 In the present invention, the filter element 1 comprises a cylindrical filter element body 15 and an end cover 16. The filter element body 15 is arranged vertically, and the end cover 16 is arranged on the top of the filter element body 15. The handle 12 is rotatably mounted on the end cover 16. Fig. 9The handle 12 is an arc-shaped structure, which is convenient for users to grasp. Two convex connecting shafts 161 are arranged opposite to each other on the radial outer periphery of the end cover 16. Through holes 124 adapted to the connecting shafts 161 are arranged at both ends of the handle 12. The positions of the through holes 124 correspond to the positions of the connecting shafts 161 one by one. The through holes 124 can be rotatably sleeved outside the corresponding connecting shafts 161 so that the handle 12 can be rotatably installed on the end cover 16.

[0047] The connection part 11 is a hexahedral structure and is arranged in the middle area of ​​the bottom of the filter element body 15. Three waterway interfaces are opened at the bottom of the connection part 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.

[0048] See also Fig.10 The middle area of ​​the waterway plate 2 is concave to form a receiving groove 21 with an upward opening, and a raw water inlet, a pure water outlet and a concentrated water outlet are arranged 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.

[0049] A rotating shaft 22 is provided at the bottom of the waterway plate 2, and the rotating shaft 22 is transversely arranged in the middle area of ​​the bottom of the waterway plate 2, and the axial direction of the rotating shaft 22 is perpendicular to the direction of the transverse movement of the locking plate 3. The arrangement of the rotating shaft 22 is conducive to improving the sensitivity of the swing of the waterway plate 2, and the rotating shaft 22 is arranged in the middle area of ​​the bottom of the waterway plate 2, which improves the stability of the assembly structure.

[0050] Two side plates 23 are arranged in parallel and at intervals on the waterway plate 2. The two side plates 23 are arranged along the lateral movement direction of the locking plate 3, and the two side plates 23 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 23. The locking plate 3 is arranged in the guide space. The utility model forms a guide space between the two side plates 23 to limit the movement direction of the locking plate 3, so as to ensure the smooth locking or unlocking of the bottom of the filter element 1.

[0051] See also Figure 1 The body 4 is provided with a cylindrical installation cavity 21 to fit the filter element 1, and the bottom of the installation cavity 21 is provided with an installation position to install the waterway plate 2, and the handle 12 is located above the installation cavity 21, so that when the handle 12 is rotated to a horizontal state, it is convenient for the user to lift and rotate the handle 12 upward. In the utility model, in the locked state, the handle 12 is in a horizontal state and faces the body 4, that is, the handle 12 faces away from the user, so as to prevent the user from accidentally touching the handle 12 to rotate and lift it.

[0052] See also Figure 3 , Figure 4 , Figure 5 and Fig.11, 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 machine body 4 is provided with a pushing block 42 corresponding to the pushing portion 31, and the upper part of the pushing block 42 is inclined from top to bottom toward the pushing portion 31 to form an inclined surface 421, and the waterway plate 2 swings back and forth relative to the machine body 4 so that the pushing portion 31 slides back and forth along the inclined surface 421. 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 42. When the waterway plate 2 swings from the inclined state to the horizontal state, the locking plate 3 swings with the waterway plate 2 and the pushing portion 31 slides downward along the inclined surface 421, so that the locking plate 3 is pushed by the pushing block 42 to move horizontally relative to the waterway plate 2 to a locked state. 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 pushing portion 31 is forced to slide upward along the inclined surface 421 to the top of the pushing block 42, so that the locking plate 3 moves horizontally relative to the waterway plate 2 to an unlocked state.

[0053] The push part 31 is provided with a sliding groove 311 extending in the lateral moving direction, and the body 4 is provided with a limit pin 43 vertically corresponding to the sliding groove 311, and the sliding groove 311 is sleeved outside the limit pin 43 so as to be lateral reciprocatingly movable. The lateral reciprocating movement of the locking plate 3 is limited by the matching limit structure of the limit pin 43 and the sliding groove 311, which improves the accuracy of the lateral moving direction of the locking plate 3 relative to the waterway plate 2, and makes the locking or unlocking of the bottom of the filter element 1 more stable and accurate.

[0054] When the waterway plate 2 swings from the horizontal state to the inclined state, the locking plate 3 needs to move horizontally to the unlocked state with the help of external force. In the present utility model, the locking plate 3 and the waterway plate 2 are elastically connected by an elastic member 5, and the elastic member 5 is arranged along the lateral movement direction of the locking plate 3. In the locked state, the elastic member 5 is in a compressed state. When the waterway plate 2 swings from the horizontal state to the inclined state, the push block 42 does not exert force on the push part 31, and the elastic force of the elastic member 5 to restore the deformation pushes the locking plate 3 to move horizontally in the opposite direction to the unlocked state, and the push part 31 slides upward along the inclined surface 421 to the top of the push block 42. In the present utility model, the elastic member 5 is a spring.

[0055] Therefore, the locking of the bottom of the filter element 1 of the utility model is achieved by the swing of the waterway plate 2 in cooperation with the push block 42 and the elastic member 5 to achieve the lateral reciprocating movement of the locking plate 3 relative to the waterway plate 2 to achieve an unlocked state or a locked state. Since the waterway plate 2 is arranged 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 bottom locking structure of the filter element 1 of the utility model utilizes the swing of the waterway plate 2 to achieve the lateral reciprocating movement of the locking plate 3, which has a simple structure and is easy to install, so it is convenient to replace the filter element 1.

[0056] See also Figure 8 and Fig.10 , the waterway plate 2 is fixed to the bottom of the filter element seat 6, the locking plate 3 is located between the filter element seat 6 and the waterway plate 2, and the filter element seat 6 is provided with a guide groove 61 adapted to the connection part 11, and the guide groove 61 is arranged correspondingly with the receiving groove 21 up and down so that the connection part 11 passes through the locking plate 3 through the guide groove 61 and is plugged into the receiving groove 21. Among them, the center of gravity of the filter element seat 6, 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 61 is opened in the middle area of ​​the filter element seat 6 and corresponds to the receiving groove 21 up and down. Therefore, during installation, the connection part 11 passes through the locking plate 3 from top to bottom through the guide groove 61 and is plugged into the receiving groove 21.

[0057] On the one hand, the filter element seat 6 is arranged above the locking plate 3, and the filter element seat 6 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 61 of the filter element seat 6, which can improve the accuracy and stability of the connection between the connection part 11 and the receiving groove 21. Therefore, the setting of the filter element seat 6 can improve the stability of the installation of the filter element 1.

[0058] The filter element seat 6 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 17, and the filter element seat 6 is provided with a matching clamping groove 63 corresponding to the clamping protrusion 17. Specifically, the semi-enclosed structure of the filter element seat 6 is an upwardly open cylindrical structure to enclose the lower part of the filter element body 15, thereby improving the stability of the connection between the filter element 1 and the waterway plate 2. The clamping protrusion 17 is provided at the lower part of the filter element body 15, and the clamping structure of the clamping protrusion 17 and the clamping groove 63 can prevent the filter element 1 from rotating relative to the filter element seat 6, thereby further improving the stability of the installation of the filter element 1.

[0059] On the basis of the above structure, at least one stopper 13 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 32 for the stopper 13 to pass through, the groove wall of the guide groove 61 is concave to form a guide channel 62 for the stopper 13 to pass through, and the number of the unlocking channels 32 and the number of the guide channels 62 are equal to the number of the stopper 13. In the assembled state, the guide channel 62 is arranged opposite to the corresponding stopper 13 up and down, and the locking plate 3 moves back and forth laterally relative to the waterway plate 2 so that the corresponding unlocking channel 32 and the stopper 13 are arranged opposite to each other up and down or staggered up and down, thereby unlocking or locking the connection part 11.

[0060] Therefore, see Fig.12 and Fig.13 The principle of locking or unlocking the bottom of the filter element 1 of the utility model is as follows:

[0061] 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 42 is higher. In this state, the filter element seat 6 and the locking plate 3 are in a synchronously inclined state with the waterway plate 2, and the elastic member 5 is in a naturally extended state so that the pushing portion 31 of the locking plate 3 is located above the push block 42, and the guide channel 62 and the corresponding unlocking channel 32 are arranged opposite to each other up and down.

[0062] When installing the filter element 1 and locking it, the filter element 1 is passed through the guide groove 61 and the locking plate 3 in sequence at the same inclination angle, and the limiter 13 is passed through the corresponding guide channel 62 and the unlocking channel 32 in sequence, so that the connection part 11 is inserted into the receiving groove 21. The filter element 1 is swung toward the body 4 to use the weight of the filter element 1 to press the waterway plate 2 and the filter element seat 6 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 421, so that the locking plate 3 is pushed by the push block 42 to move horizontally relative to the waterway plate 2 to the unlocking channel 32 and the corresponding limiter 13 and the guide channel 62 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 13 to prevent the limiter 13 from disengaging upward from the guide channel 62, thereby locking the connection part 11 and completing the locking of the bottom of the filter element 1. At this time, the elastic member 5 is in a compressed state.

[0063] When unlocking and removing the filter element 1, the filter element 1 is swung away from the body 4 to use the weight of the filter element 1 to press the waterway plate 2 and the filter element seat 6 to swing in opposite directions to an inclined state. The locking plate 3 swings with the waterway plate 2 and the locking plate is driven by the elastic force of the elastic member 5 to restore the deformation so that the pushing portion 31 slides upward along the inclined surface 421 to the top of the pushing block 42, so that the locking plate 3 moves laterally relative to the waterway plate 2 until the unlocking channel 32 and the corresponding limit member 13 and guide channel 62 are arranged opposite to each other up and down. The limit member 13 can be disengaged upward through the corresponding unlocking channel 32 and guide channel 62, thereby unlocking the connecting portion 11 and completing the unlocking of the bottom of the filter element 1.

[0064] For the locking structure at the top of filter element 1, refer to Figure 2 and Figure 6-9 The handle 12 includes a handle portion 121 and a limiting portion 122. The handle portion 121 is an arc-shaped structure. The limiting portion 122 is provided with two and is respectively located at the two ends of the handle portion 121. The limiting portion 122 is rotatably mounted on the top of the filter element 1, and the center of gravity of the limiting portion 122 is offset, which has a tendency to drive the handle 12 to rotate toward the body 4 to be horizontally stored at the top of the filter element 1. The outer side of the limiting portion 122 extends horizontally away from the filter element 1 to form a block 123. The body 4 is provided with a stopper 44 corresponding to the block 123. The stopper 44 is provided on the outer side of the top of the installation cavity 41. In the locked state, the limiting portion 122 is sandwiched between the filter element 1 and the stopper 44, and the stopper 44 is provided on the side of the block 123 away from the body 4.

[0065] Specifically, the handle portion 121 is the main part of the handle 12, which is used for the user to grasp, rotate, lift the handle 12, etc. The handle portion 121 is designed as an arc structure for the user to grasp. The through hole 124 is opened in the limit portion 122, and the limit portion 122 is rotatably mounted on the corresponding connecting shaft 161 through the through hole 124 so that the limit portion 122 is rotatably installed on the end cover 16, so that the handle 12 is rotatably installed on the end cover 16.

[0066] The utility model designs the limiting part 122 located at the two end parts as a gravity center offset structure. Compared with the handle part 121, the rotation range of the limiting part 122 is smaller. When it rotates from a vertical state to a horizontal state due to its own weight, the impact force of the limiting part 122 on the end cover 16 is smaller, thereby having less impact on the stability of the filter element 1.

[0067] In the present invention, the center of gravity offset structure of the limiter 122 enables the handle 12 to automatically rotate to be horizontally stored at the top of the filter element 1, and when the handle 12 is in a horizontal state, the limiter 122 is sandwiched between the stopper 44 and the end cover 16, which can prevent the limiter 122 from being separated from the connecting shaft 161. The setting of the block 123 can be limited by the stopper 44 to prevent it from swinging or shaking away from the body 4, thereby locking the top of the filter element 1.

[0068] The top of the filter element 1 is provided with a storage groove 14 adapted to the handle 12. The storage groove 14 includes a handle groove 141 adapted to the handle portion 121 and a limit groove 142 adapted to the limit portion 122. The limit groove 142 is arranged at both ends of the handle groove 141, and the limit groove 142 extends downward relative to the handle groove 141. The ends of the limit groove 142 close to and away from the handle groove 141 are both arc-shaped structures. That is, the limit portion 122 achieves the center of gravity offset through an asymmetric structure. The design of the storage groove 14 can store the handle 12 horizontally to prevent the handle 12 from rotating downward, and ensure that the rotation angle of the handle 12 is 90°, and it will not rotate to a horizontal state with its back to the body 4, so as to ensure that the handle 12 is arranged horizontally toward the body 4 in the locked state. The arc-shaped structure design of the limit portion 122 and the limit groove 142 can improve the smoothness of the rotation of the limit portion 122, so as to quickly unlock or lock the top of the filter element 1.

[0069] The handle 121 is located on the side where the center of gravity is offset and is concave, so that the handle 121 forms a step structure. When the handle 12 is locked horizontally, the lower part of the handle 121 is concave compared to the upper part to form a step structure, which is convenient for the user to lift the handle 121 upward to rotate the handle 12.

[0070] Therefore, the principle of locking or unlocking the top of the filter element 1 of the utility model is as follows:

[0071] In the unassembled state, the user rotates the handle 12 to a vertical state to lift the filter element 1 by the handle 12 .

[0072] When installing and locking the filter element 1, the user lifts the filter element with the handle 12 and inserts it obliquely into the receiving groove 21, and uses the handle 12 to swing the filter element 1 toward the body 4 to a horizontal state to lock the bottom of the filter element 1. Then, the user releases the handle 12, and the handle 12 automatically rotates toward the body 4 to a horizontal state and is stored in the receiving groove 14 due to the center of gravity offset of the limiting portion 122. At this time, the limiting portion 122 is sandwiched between the end cover 16 and the stopper 44 to prevent the limiting portion 122 from detaching from the connecting shaft 161. And the stopper 44 is blocked on the side of the block 123 facing away from the body 4, thereby preventing the filter element 1 from tilting away from the body 4. In this way, the top of the filter element 1 is locked.

[0073] When unlocking and removing the filter element 1, the user lifts the handle 12 upward and rotates it to a vertical state to unlock the top of the filter element 1. The filter element 1 is swung to an inclined state with the handle 12 facing away from the body 4 to unlock the bottom of the filter element 1. At this time, the user lifts the filter element 1 by the handle 12 to complete the removal of the filter element 1.

[0074] In addition to the above filter element assembly, the utility model also provides a water purifier, which includes a sealing plate 7 and the above filter element assembly, and the sealing plate 7 is installed at the opening of the body 4. When the filter element 1 needs to be installed or removed, the sealing plate 7 is removed from the body 4, and the filter element 1 can be operated.

[0075] The filter element 1 in the water purifier of the present invention is designed with locking structures at the bottom and the top, so that the filter element 1 can be stably installed in the water purifier, ensuring the smooth use of the water purifier.

[0076] The technical means disclosed in the solution of the utility model 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 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.
