[0002] A water purifier is a water treatment device that deeply purifies water quality according to the usage requirements of water. Its working principle is to introduce raw water into the filter element cylinder. Under the action of pressure, water molecules and beneficial minerals pass through the filter element and flow out. After being filtered by multiple filter elements, it becomes purified water, while harmful substances such as bacteria, colloids, rust, and suspended substances are retained in the filter element, thus achieving the effect of filtration and purification.

[0003] When the multiple filter elements of the existing water purifier are connected in series through pipelines, in order to ensure the sealing performance, the connection structure between the filter element cylinder and the pipeline joint is relatively complex, resulting in troublesome disassembly and assembly of the filter element, and then difficult replacement and maintenance of the filter element. Moreover, during the actual production of the existing water purifier, the number of filter elements can also be increased or decreased according to the water quality differences in different regions to meet the needs of users in different regions. However, the troublesome disassembly and assembly of the filter element also make the operation of increasing or decreasing the number of filter elements difficult, thus reducing the production efficiency and unable to meet the current production requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 7 , a rapid filter element assembly structure of an embodiment of the present utility model, which includes a clamping member provided on a filter element cylinder 1 and a connector 2 provided on a connecting pipeline. A buckle member is provided on the connector 2, and the buckle member cooperates with the clamping member to fix the filter element cylinder 1 on the connector 2; a disconnection member 3 is further provided on the connector 2, and the disconnection member 3 is used to disengage the clamping member from the buckle member.

[0034] For the multi-stage filter elements of existing water purifiers, when connecting the multi-stage filter elements in series through a connecting pipeline, the pipeline connectors at both ends of the connecting pipeline are fixedly connected to the filter element cylinders 1 of two adjacent filter elements, so as to realize the series connection of two adjacent filter elements. The connection structure between the filter element cylinder 1 of the existing filter element and the pipeline connector of the connecting pipeline is relatively complex, resulting in troublesome disassembly and assembly of the filter element, and then difficult replacement and maintenance of the filter element.

[0035] Moreover, during the actual production of existing water purifiers, the number of filter elements can also be increased or decreased according to the water quality differences in different regions to meet the needs of users in different regions. However, the troublesome disassembly and assembly of the filter elements will also make it difficult to increase or decrease the number of filter elements, thereby reducing production efficiency and unable to meet the current production requirements.

[0036] Therefore, in this application, the rapid filter element assembly structure includes a clamping member provided on the filter element cylinder 1 and a connector 2 provided on the connecting pipeline, and a buckle member is provided on the connector 2. Through the cooperation of the clamping member and the buckle member, the fixed connection between the filter element cylinder 1 and the connector 2 can be realized, so as to realize the fixed connection between the filter element and the connecting pipeline, and the connecting pipeline connects two adjacent filter elements in series.

[0037] A disconnection member 3 is further provided on the connector 2. Through the disconnection member 3, the clamping member can be disengaged from the buckle member, so that the filter element cylinder 1 is disengaged from the connector, realizing the disassembly of the filter element on the connecting pipeline. Furthermore, the disassembly and assembly of the filter element are simple and convenient, easy to implement, convenient for the replacement and maintenance of the filter element, and convenient for increasing or decreasing the number of filter elements to meet the needs of users in different regions.

[0038] In this embodiment, the clamping member is the telescopic head 11 provided on the filter element cylinder 1. The buckling member includes a rotating groove 21 circumferentially provided on the inner side of the connecting head 2, and a stopping member 22 provided on one side of the rotating groove 21. When the telescopic head 11 extends on the filter element cylinder 1, it can be rotationally engaged with the rotating groove 21. The stopping member 22 is used to limit the rotation of the telescopic head 11 in the rotating groove 21, and the disconnecting member 3 is used to push the telescopic head 11 to contract on the filter element cylinder 1.

[0039] In this application, a telescopic head 11 is provided on the filter element cylinder 1. The telescopic head 11 can extend radially on the filter element cylinder 1 and can also retract radially into the filter element cylinder 1. Initially, the telescopic head 11 is in the extended state on the filter element cylinder 1, and a rotating groove 21 is circumferentially provided on the inner side of the connecting head 2. When connecting the filter element cylinder 1 and the connecting head 2, the filter element cylinder 1 can be rotated so that the telescopic head 11 in the extended state on the filter element cylinder 1 rotates along the rotating groove 21 until it abuts against the end of the rotating groove 21.

[0040] A stopping member 22 is provided on one side of the rotating groove 21. When one side of the telescopic head 11 in the extended state abuts against the end of the rotating groove 21, the stopping member 22 limits the other side of the telescopic head 11, restricting the rotation of the telescopic head 11 in the rotating groove 21, thereby realizing the fixed connection between the filter element cylinder 1 and the connecting head 2, and further realizing the fixed connection between the filter element and the connecting pipeline.

[0041] When disconnecting the filter element cylinder 1 and the connecting head 2, the disconnecting member 3 on the connecting head 2 can be used to push the telescopic head 11 to retract radially into the filter element cylinder 1, so that the telescopic head 11 is disengaged from the rotating groove 21, enabling the filter element cylinder 1 to be detached from the connecting head 2, realizing the disassembly of the filter element on the connecting pipeline. Furthermore, the disassembly and assembly of the filter element are simple and convenient, easy to implement, facilitating the replacement and maintenance of the filter element, and facilitating the increase or decrease of the number of filter elements to meet the needs of users in different regions.

[0042] In this embodiment, a first installation groove 12 is provided radially on the filter element cylinder 1. The telescopic head 11 includes a first spring 111 provided in the first installation groove 12 and a plug 112 provided at the end of the first spring 111. The plug 112 can extend or retract in the first installation groove 12. In this application, the telescopic head 11 includes a first spring 111 and a plug 112. The first spring 111 is arranged in the first installation groove 12, and the plug 112 is arranged at the end of the first spring 111. Since the first installation groove 12 is arranged radially on the filter element cylinder 1, the plug 112 can extend or retract radially on the filter element cylinder 1.

[0043] Initially, the first spring 111 is in a natural elongation state, and the bolt 112 is in a protruding state on the filter element cylinder 1. By rotating the filter element cylinder 1, the bolt 112 in the protruding state on the filter element cylinder 1 rotates along the rotation groove 21 until it abuts against the end of the rotation groove 21. At this time, the end of the rotation groove 21 limits one side of the bolt 112, and the stopper 22 limits the other side of the bolt 112, thereby restricting the rotation of the bolt 112 in the rotation groove 21. At the same time, the bolt 112 remains in a plugged state with the rotation groove 21, thus realizing the fixed connection between the filter element cylinder 1 and the connector 2.

[0044] When disconnecting the filter element cylinder 1 from the connector 2, a separating member 3 on the connector 2 can apply a force radially towards the filter element cylinder 1 to the bolt 112, compressing the first spring 111, thereby pushing the bolt 112 to retract radially into the filter element cylinder 1, causing the bolt 112 to disengage from the rotation groove 21, and then enabling the filter element cylinder 1 to be detached from the connector 2, realizing the disassembly of the filter element on the connecting pipeline.

[0045] After the filter element cylinder 1 is detached from the connector 2, under the elastic force of the first spring 111 recovering its own deformation, the bolt 112 returns to the state of protruding radially on the filter element cylinder 1 until the first spring 111 returns to the natural elongation state.

[0046] In this embodiment, the buckle member further includes an opening 211 that communicates the rotation groove 21 with the outside in the axial direction. When the telescopic head 11 protrudes on the filter element cylinder 1, it can enter the rotation groove 21 along the opening 211. In this application, an opening 211 is also provided inside the connector 2, and the opening 211 communicates the rotation groove 21 with the outside in the axial direction.

[0047] When connecting the filter element cylinder 1 and the connector 2, first, the bolt 112 in the protruding state on the filter element cylinder 1 enters the rotation groove 21 along the opening 211, and then the filter element cylinder 1 is rotated to drive the bolt 112 to rotate synchronously in the rotation groove 21 until the bolt 112 abuts against the end of the rotation groove 21. Thereby, the end of the rotation groove 21 limits one side of the bolt 112, and the stopper 22 limits the other side of the bolt 112, restricting the rotation of the bolt 112 in the rotation groove 21. At the same time, the bolt 112 remains in a plugged state with the rotation groove 21, thus realizing the fixed connection between the filter element cylinder 1 and the connector 2.

[0048] In this embodiment, a second installation groove 23 is provided at the bottom of the rotation groove 21. The stop member 22 includes a stop seat 221 disposed in the second installation groove 23, a stop block 222 rotatably connected to the stop seat 221, and a second spring 223 having one end connected to the stop seat 221 and the other end connected to the stop block 222. When the telescopic head 11 rotates along the rotation groove 21, the stop block 222 can be pressed into the second installation groove 23. When the telescopic head 11 rotates to the end of the rotation groove 21, the stop block 222 extends out of the second installation groove 23 to limit the rotation of the telescopic head 11 in the rotation groove 21.

[0049] In this application, a second installation groove 23 is provided at the bottom of the rotation groove 21, and the second installation groove 23 communicates with the rotation groove 21. The stop member 22 includes a stop seat 221, a stop block 222, and a second spring 223. The stop seat 221 is disposed in the second installation groove 23. The stop block 222 is rotatably connected to the stop seat 221 through a rotating shaft, so that the stop block 222 can rotate on the stop seat 221. One end of the second spring 223 is connected to the stop seat 221 and the other end is connected to the middle of the stop block 222.

[0050] Initially, the second spring 223 is in a natural elongation state. Through the support of the second spring 223, the stop block 222 is inclined at a certain angle on the stop seat 221, and the top of the stop block 222 extends into the rotation groove 21 from the second installation groove 23. When the plug 112 in the extended state on the filter element cylinder 1 enters the rotation groove 21 along the opening 211, by rotating the filter element cylinder 1, the plug 112 is driven to rotate synchronously in the rotation groove 21.

[0051] When the plug 112 rotates to the position of the stop block 222 in the rotation groove 21, it passes over the top of the stop block 222 and applies a force to the stop block 222, causing the stop block 222 to rotate downward around the rotating shaft on the stop seat 221, and the second spring 223 is compressed, so as to press the stop block 222 into the second installation groove 23, enabling the plug 112 to continue to rotate in the rotation groove 21.

[0052] After the plug 112 passes over the top of the stop block 222, the plug 112 reaches the end of the rotation groove 21. Under the elastic force of the second spring 223 to restore its own deformation, the stop block 222 rotates upward around the rotating shaft on the stop seat 221, so that the stop block 222 returns to the state where the top extends into the rotation groove 21 from the second installation groove 23, and the second spring 223 returns to the natural elongation state. Thus, the end of the rotation groove 21 limits one side of the plug 112, and the top of the inclined stop block 222 limits the other side of the plug 112, restricting the rotation of the plug 112 in the rotation groove 21.

[0053] In this embodiment, the connector 2 is provided with a third installation groove 24 in the radial direction, which communicates the rotation groove 21 with the outside. The disconnection member 3 includes a push rod 31 that moves radially in the third installation groove 24 and a driving member provided outside the connector 2. The driving member is used to drive the push rod 31 to move radially toward the rotation groove 21 until the push rod 31 extends into the rotation groove 21. The push rod 31 abuts against the telescopic head 11 to push the telescopic head 11 to contract on the filter cartridge body 1.

[0054] In this application, the connector 2 is further provided with a third installation groove 24. The third installation groove 24 is located outside the rotation groove 21 and communicates the rotation groove 21 with the outside in the radial direction. The disconnection member 3 includes a push rod 31 and a driving member. The push rod 31 is arranged in the third installation groove 24. Since the third installation groove 24 communicates the rotation groove 21 with the outside in the radial direction, the push rod 31 can move radially in the third installation groove 24 to the rotation groove 21, and the driving member is arranged outside the connector 2.

[0055] Initially, the end of the push rod 31 close to the rotation groove 21 is located in the third installation groove 24. When the bolt 112 rotates in the rotation groove 21 until the bolt 112 abuts against the end of the rotation groove 21, the central axis of the push rod 31 coincides with the central axis of the bolt 112. Therefore, through the driving member located outside the connector 2, the push rod 31 is pushed to move in the third installation groove 24 toward the rotation groove 21, so that the push rod 31 extends into the rotation groove 21 and abuts against the bolt 112. The push rod 31 can apply a radial force toward the filter cartridge body 1 to the bolt 112, compress the first spring 111, thereby pushing the bolt 112 to retract radially into the filter cartridge body 1, separating the bolt 112 from the rotation groove 21, and further enabling the filter cartridge body 1 to be detached from the connector 2, realizing the disassembly of the filter element on the connecting pipeline.

[0056] In this embodiment, the disconnection member 3 further includes a third spring 32 arranged in the third installation groove 24. The third spring 32 is used to push the push rod 31 to reset in the third installation groove 24. In this application, the disconnection member 3 further includes a third spring 32, and the third spring 32 is arranged in the third installation groove 24. Initially, the third spring 32 is in a natural elongation state, and the end of the push rod 31 close to the rotation groove 21 is located in the third installation groove 24. When the driving member pushes the push rod 31 to move in the third installation groove 24 toward the rotation groove 21, so that the push rod 31 applies a radial force toward the filter cartridge body 1 to the bolt 112, the third spring 32 is compressed.

[0057] When the bolt 112 is disengaged from the rotation groove 21 and the filter element cylinder body 1 is detached from the connector 2, the driving member no longer applies a thrust force to the push rod 31. Under the elastic force of the third spring 32 restoring its own deformation, the push rod 31 moves in the third installation groove 24 in a direction away from the rotation groove 21 until the end of the push rod 31 close to the rotation groove 21 retracts into the third installation groove 24, and the third spring 32 returns to its natural elongation state, thereby realizing the automatic reset of the push rod 31 through the third spring 32.

[0058] In this embodiment, the disconnecting member 3 further includes a top pin 33 provided at the end of the push rod 31, and the driving member is a collar 34 rotatably connected to the connector 2. A slope groove 341 is provided on the inner side of the collar 34, and the slope groove 341 cooperates with the top pin 33 to push the push rod 31 to move radially in a direction close to the rotation groove 21 when the collar 34 rotates. In this application, the disconnecting member 3 further includes a top pin 33, and the top pin 33 is provided at one end of the push rod 31 away from the rotation groove 21. The driving member is a collar 34 sleeved outside the adapter, and the collar 34 is rotatably connected to the connector 2.

[0059] A slope groove 341 is provided on the inner side of the collar 34. The top pin 33 provided at one end of the push rod 31 away from the rotation groove 21 extends out of the third installation groove 24, and the end of the top pin 33 abuts against the slope groove 341. When the collar 34 is rotated outside the connector 2, through the cooperation of the slope groove 341 and the top pin 33, the push rod 31 is pushed to move in the third installation groove 24 in a direction close to the rotation groove 21, and the third spring 32 is compressed, so that the push rod 31 extends into the rotation groove 21, and a force is applied to the bolt 112 radially toward the filter element cylinder body 1 until the bolt 112 is disengaged from the rotation groove 21, thereby realizing the disassembly of the filter element on the connecting pipeline.

[0060] When the collar 34 is rotated reversely outside the connector 2, the slope groove 341 and the top pin 33 cooperate and no longer apply a force to the push rod 31 to move in a direction close to the rotation groove 21. At this time, under the elastic force of the third spring 32 restoring its own deformation, the push rod 31 moves in the third installation groove 24 in a direction away from the rotation groove 21, and at the same time keeps the top pin 33 in contact with the slope groove 341 until the end of the push rod 31 close to the rotation groove 21 retracts into the third installation groove 24, and the third spring 32 returns to its natural elongation state, thereby realizing the automatic reset of the push rod 31 through the third spring 32.

[0061] Specifically, in this application, the third spring 32 located in the third installation groove 24 is sleeved on the push rod 31, and one end of the third spring 32 is fixedly connected to the inner wall of the third installation groove 24, and the other end abuts against one end of the top pin 33 close to the push rod 31, so that when the top pin 33 and the push rod 31 move in a direction close to the rotation groove 21 under the action of an external force, the third spring 32 is compressed.

[0062] When the external forces applied to the top pin 33 and the push rod 31 are removed, under the action of the elastic force of the third spring 32 to restore its own deformation, the top pin 33 and the push rod 31 are pushed to move away from the rotation groove 21, so that the top pin 33 remains in contact with the slope groove 341, and one end of the push rod 31 close to the rotation groove 21 retracts into the third installation groove 24.

[0063] In this embodiment, a first sealing groove 13 is provided at the top of the filter element cylinder body 1, a second sealing groove 25 is provided on the connector 2, and the filter element quick assembly structure further includes a sealing ring 4 embedded in the first sealing groove 13 and the second sealing groove 25. In this application, the filter element quick assembly structure further includes a sealing ring 4.
