[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, rather than all, of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0035] Please refer to Figures 1-3 , a multi-stage backwashing self-cleaning ultrafiltration water purifier provided by an embodiment of the present invention includes an integrated base 1 and a plurality of filter cartridges 2. A first jack 3 and a second jack 4 are provided at the bottom of the integrated base 1. A first insertion tube 5 and a second insertion tube 6 are provided on the filter cartridge 2. The length of the first insertion tube 5 is greater than that of the second insertion tube 6. The multi-stage backwashing self-cleaning ultrafiltration water purifier further includes: a locking member 7 movably disposed in the entity of the integrated base 1 between the first jack 3 and the second jack 4; a card slot 8 is provided on the outer wall of the first insertion tube 5, and one end of the locking member 7 corresponds to the first jack 3 and is matched with the card slot 8; the other end of the locking member 7 corresponds to the second jack 4 and is wedge-fitted with the upper end of the second insertion tube 6; a limiting member 9 is provided on the locking member 7 to limit the locking member 7 to move only in one direction towards the first jack 3.

[0036] Specifically, a water flow control circuit, a control valve, and corresponding drive structures and circuit systems are provided inside the integrated base 1; the first jack 3 and the second jack 4 are in a group and are correspondingly connected to the same filter cartridge 2; two pipe orifices, namely a first insertion pipe 5 and a second insertion pipe 6, are provided on the filter cartridge 2 for normally filtering the water source during forward water flow and for backwashing inside the filter cartridge 2 during reverse water flow, so that the self-cleaning function inside the filter cartridge 2 can be realized. Sealing gaskets are provided at the deepest positions of the first jack 3 and the second jack 4 to ensure sealed connection with the first insertion pipe 5 and the second insertion pipe 6. The first jack 3 and the second jack 4 are arranged parallel to each other in the axial direction, and the moving direction of the locking member 7 is arranged perpendicular to the axial direction of the above-mentioned jacks; the length of the locking member 7 is greater than the minimum distance between the first jack 3 and the second jack 4; the height where the card slot 8 is located is close to the upper end of the second insertion pipe 6, and the taper of the card slot 8 is the same as that of the upper end of the second insertion pipe 6; the initial position of the locking member 7 is set such that one end does not extend into the first jack 3, while the other end remains extending into the second jack 4. In actual use of this technical solution, when the integrated base 1 and the filter cartridge 2 are assembled, the first insertion pipe 5 and the second insertion pipe 6 are simultaneously inserted into the first jack 3 and the second jack 4 respectively, and the first insertion pipe 5 is longer and thus passes through the position of the locking member 7 first. Subsequently, the card slot 8 on the first insertion pipe 5 gradually corresponds to the locking member 7, and at the same time, the upper end of the second insertion pipe 6 undergoes a wedge-shaped extrusion with one end of the locking member 7, so that one end of the locking member 7 slowly embeds into the card slot 8, and under the action of the limiting member 9, the locking member 7 cannot move back, thereby realizing automatic limiting of the first insertion pipe 5 in the first jack 3, that is, realizing automatic locking of the assembly of the integrated base 1 and the filter cartridge 2 and improving the assembly efficiency.

[0037] Compared with the prior art, in a multi-stage backwashing self-cleaning ultrafiltration water purifier proposed in an embodiment of the present invention, by providing the locking member 7, when the integrated base 1 and the filter cartridge 2 are assembled, the first insertion pipe 5 and the second insertion pipe 6 are simultaneously inserted into the first jack 3 and the second jack 4 respectively, and the first insertion pipe 5 is longer and thus passes through the position of the locking member 7 first. Subsequently, the card slot 8 on the first insertion pipe 5 gradually corresponds to the locking member 7, and at the same time, the upper end of the second insertion pipe 6 undergoes a wedge-shaped extrusion with one end of the locking member 7, so that one end of the locking member 7 slowly embeds into the card slot 8, and under the action of the limiting member 9, the locking member 7 cannot move back, thereby realizing automatic limiting of the first insertion pipe 5 in the first jack 3, that is, realizing automatic locking of the assembly of the integrated base 1 and the filter cartridge 2 and improving the assembly efficiency.

[0038] As a preferred technical solution of this embodiment, the limiting member 9 is elastically tilted, and a movable groove 10 matching the locking member 7 is provided in the integrated seat 1, and an advance groove 11 matching the limiting member 9 is provided on the inner wall of the movable groove 10. Specifically, the locking member 7 and the limiting member 9 are made of a metal material or other material with a certain strength; the free end of the limiting member 9 remains elastically tilted; a protrusion is provided in the middle position of the advance groove 11, and when the locking member 7 is in the initial position, the free end of the limiting member 9 is tilted in the advance groove 11 near the second insertion position. One end of the hole 4, that is, the raised portion is close to the second plug hole 4; and when the locking member 7 is squeezed by the second plug tube 6 and one end is embedded in the slot 8, the movement of the locking member 7 drives the limiting member 9 to be squeezed through the raised portion, and then the limiting member 9 elastically tilts up again to be in the advance groove 11 close to the end of the first plug hole 3, that is, the raised portion is close to the first plug hole 3. At this time, the movement of the limiting member 9 away from the first plug hole 3 is restricted by the raised portion in the advance groove 11, that is, the locking member 7 remains embedded in the slot 8 to limit the first plug tube 5 to be in the first plug hole 3.

[0039] See also Figures 1-10 A manufacturing device provided by an embodiment of the present invention is used to manufacture the above-mentioned multi-stage backwashing self-cleaning ultrafiltration water purifier, including a side platform 13 arranged on the side of a track 12 for conveying filter cartridges 2, the end of the track 12 is set as an assembly position, and also includes: a positioning trolley 14, which is movably arranged on the side platform 13, one side of which faces the track 12 and is movably provided with a bracket 15, and the bracket 15 is fixedly provided with a first fork body 16, a second fork body 17 and a third fork body 18 in sequence against the conveying direction of the filter cartridge 2, and a distance control component is arranged between each fork body, the bracket 15 can be movably close to the track 12 so that each fork body corresponds to a single filter cartridge 2. Then, during the process of the positioning trolley 14 driving each fork body to move to the assembly position of the track 12, the distance control component is linked to separate each fork body at equal distances.

[0040] Specifically, the upper end of the filter cartridge 2 is arranged in a stepped shape with a gradually increasing diameter upwards, and the track 12 is arranged horizontally. The track 12 is a parallel bilateral support structure that can support the upper end of the filter cartridge 2. A driving assembly can be integrated on the track 12, and the driving assembly pushes the filter cartridge 2 to slide along the track 12. Such driving assemblies are prior art, such as conveyor belts or intermittent levers, which are not described in detail; the track 12 is fixed on a frame that supports the device on the ground; the end assembly position of the track 12 is used to determine the number and spacing of the filter cartridges 2, and then, it can be conveniently assembled with the same integrated seat 1. The side platform 13 is arranged on one side of the track 12, and is used to carry a structure for automatically operating the filter cartridge 2. A guide rail extending in a direction parallel to the track 12 is arranged on the side platform 13, and a positioning trolley 14 is movably connected to the guide rail and controlled by a servo system. The positioning trolley 14 moves back and forth between the assembly position of the corresponding track 12 and the part before the assembly position. A telescopic unit 35 is installed on the positioning trolley 14, and the output end of the telescopic unit 35 is connected to the bracket 15. The telescopic unit 35 can preferably be an electric telescopic rod, a hydraulic telescopic rod, etc.; the movable direction of the bracket 15 is perpendicular to the extension direction of the track 12, that is, the bracket 15 moves straight towards or away from the track 12; the first fork body 16, the second fork body 17 and the third fork body 18 have the same specifications and are U-shaped. The inner wall width is consistent with the diameter of the corresponding height of the filter cartridge 2, but it will not limit the axial rotation of the filter cartridge 2; the distance control component is used to control the distance between the first fork body 16 and the second fork body 17 and the distance between the second fork body 17 and the third fork body 18 to remain consistent and change synchronously; in the actual installation of multiple filter cartridges 2 and the same integrated seat 1, it is necessary to maintain a preset interval between each filter cartridge 2. In actual use of the present technical solution, three filter cartridges 2 to be installed are grouped together and transported on the track 12 to a position before the assembly position. The positioning trolley 14 drives each fork body to correspond to the three filter cartridges 2 one by one, and then the telescopic unit 35 pushes the bracket 15 toward the track 12, that is, drives each fork body to engage with a filter cartridge 2 respectively. Then, the positioning trolley 14 can move toward the end of the track 12, and then drive a group of three filter cartridges 2 toward the assembly position through each fork body. When the filter cartridge 2 approaches the assembly position, the distance control component is linked to separate the forks equidistantly to the specified distance, thereby facilitating subsequent assembly with the integrated seat 1.

[0041] As a preferred technical solution of this embodiment, a positioning unit 19 for blocking or releasing the filter cartridge 2 is provided on the track 12 before the assembly position. When the bracket 15 approaches the track 12, the positioning unit 19 releases the filter cartridge 2. Specifically, the positioning unit 19 is preferably a telescopic baffle structure. When the filter cartridge 2 is prepared, the positioning unit 19 blocks between the assembly positions until the three filter cartridges 2 are successively transferred to the position against the positioning unit 19. At this time, the positioning trolley 14 can conveniently find the position of each filter cartridge 2 at one end of the moving range. Subsequently, when the positioning trolley 14 drives the bracket 15 and each fork body to approach the filter cartridge 2, the positioning unit 19 releases the filter cartridge 2.

[0042] As a preferred technical solution of this embodiment, a chute 20 is provided inside the bracket 15. The second fork body 17 and the third fork body 18 are movably connected to the chute 20 on the side away from the track 12. Specifically, a handle rod is provided on the side of each fork body away from the track 12. The end of the handle rod of the first fork body 16 is fixed on the bracket 15, while the end of the handle rod of the second fork body 17 and the third fork body 18 is embedded in the chute 20 and slidably connected.

[0043] As a preferred technical solution of this embodiment, the distance control assembly includes a first linkage rod 21 rotatably provided on the first fork body 16. One end of the first linkage rod 21 is in screw drive connection with the second fork body 17 and coaxially connected with a first gear 22. A trigger assembly is provided at the other end of the first linkage rod 21. The trigger assembly triggers and drives the first linkage rod 21 to rotate when the fork bodies drive the filter cartridge 2 close to the assembly position. A second linkage rod 23 is rotatably provided on the second fork body 17. A second gear 24 that remains in mesh with the first gear 22 is provided on the second linkage rod 23. One end of the second linkage rod 23 is in screw drive connection with the third fork body 18. Specifically, the first linkage rod 21 and the second linkage rod 23 are axially parallel to each other and parallel to the moving direction of the filter cartridge 2 on the track 12; the pitch of the screw structure provided by the screw drive connection between the first linkage rod 21 and the second fork body 17 satisfies that when the second fork body 17 axially moves relative to the first linkage rod 21, it triggers the first linkage rod 21 to axially rotate. In other words, the screw structure provided by the screw drive connection between the first linkage rod 21 and the second fork body 17 is not in the form of a thread and will not cause transmission self-locking; the screw drive connection structure between the first linkage rod 21 and the second fork body 17 and the screw drive connection structure between the second linkage rod 23 and the third fork body 18 are the same, with the same pitch, but the spiral directions are set opposite to each other, thereby matching the meshing transmission of the first gear 22 and the second gear 24; the axial distance of the second gear 24 covers the axial movement of the first gear 22 relative to the second fork body 17, thereby ensuring that when the first linkage rod 21 is triggered to rotate and the second fork body 17 moves relative to the first fork body 16, the first gear 22 and the second gear 24 always remain in meshing transmission; under the trigger of the trigger assembly, the rotation of the first linkage rod 21 is driven, so that the second fork body 17 and the first linkage rod 21 undergo screw drive to move away from the first fork body 16. At the same time, the first linkage rod 21 drives the second linkage rod 23 to rotate, so that the third fork body 18 and the second linkage rod 23 undergo screw drive to move away from the second fork body 17, that is, the distance between the first fork body 16 and the second fork body 17 and the distance between the second fork body 17 and the third fork body 18 are synchronously expanded to a preset size.

[0044] As a further preferred technical solution of this embodiment, the trigger assembly includes a top sleeve 25 which is spirally sleeved at one end of the first linkage rod 21 away from the first gear 22. The top sleeve 25 is only axially movably connected to the first fork body 16. A top plate 26 matching the top sleeve 25 is fixedly arranged on the side platform 13 near the end of the track 12. When the bracket 15 is away from the track 12, the top sleeve 25 is axially offset from the top plate 26. A first elastic member 27 connected to the second fork body 17 is arranged in the slide groove 20. The first elastic member 27 keeps pulling the second fork body 17 close to the first fork body 16. Specifically, the initial position of the top sleeve 25 is set so that one end exceeds The first fork body 16 is close to the side wall of the top plate 26, so when the first fork body 16 approaches the end of the track 12, the top sleeve 25 first abuts against the top plate 26, and when each filter cartridge 2 reaches the assembly position of the track 12, the first fork body 16 will not interact with the top plate 26; a guide column is provided on the first fork body 16, and a guide sleeve movably sleeved on the guide column is provided on the side wall of the top sleeve 25, and the axial direction of the guide column is parallel to the axial direction of the first linkage rod 21; the spiral transmission connection between the top sleeve 25 and the first linkage rod 21 is not a threaded type, and does not have a transmission self-locking function, and the spiral transmission pitch satisfies the axial movement of the top sleeve 25 to drive the first linkage rod 21 to rotate. In actual use of the present technical solution, at a position before the assembly position of the track 12, the bracket 15 is driven by the telescopic unit 35 to approach the track 12 so that each fork body engages with the corresponding filter cartridge 2, and then driven by the positioning trolley 14, the bracket 15 as a whole approaches the top plate 26, that is, the top sleeve 25 can correspond to the top plate 26 in the axial direction. When each filter cartridge 2 approaches the assembly position, the top sleeve 25 abuts against the top plate 26, and the top sleeve 25 moves axially close to the first fork body 16, thereby triggering the spiral transmission between the first linkage rod 21, so that the first linkage rod 21 rotates, thereby triggering each fork body to move away from each other to reach a preset distance, and when each filter cartridge 2 abuts against the top plate 26, the top sleeve 25 moves axially close to the first fork body 16, thereby triggering the spiral transmission between the first linkage rod 21, and the first linkage rod 21 rotates, thereby triggering each fork body to move away from each other to reach a preset distance, and when each filter cartridge 2 abuts against the top plate 26, the top sleeve 25 moves axially close to the first fork body 16, and then triggers the spiral transmission between the first linkage rod 21 and the first linkage rod 21. After reaching the assembly position, the position of each filter cartridge 2 is accurate, and the integrated seat 1 can be directly assembled on the upper end of each filter cartridge 2 from top to bottom by the mechanical arm. After the integrated seat 1 and each filter cartridge 2 are initially connected, the bracket 15 is driven away from the track 12 by the telescopic unit 35, and then drives each fork body to separate from the filter cartridge 2, and the top sleeve 25 is axially dislocated from the top plate 26. Due to the triggering of the first elastic member 27, the second fork body 17 is pulled back to the first fork body 16, and then the reversal of the first linkage rod 21 is passively triggered. On the one hand, the third fork body 18 is moved closer to the second fork body 17, and on the other hand, the linkage top sleeve 25 is returned to the initial position.

[0045] Due to the functional requirements of the filter cartridge 2, the first insert tube 5 and the second insert tube 6 disposed at the upper end thereof must also be positioned in the correct direction during installation.

[0046] In another embodiment proposed by the present invention, a friction plate 28 is provided on one side of the track 12. When the filter cartridge 2 moves on the track 12 and passes by the friction plate 28, the upper sidewall of the filter cartridge 2 can roll by friction with the friction plate 28. The first insertion tube 5 is arranged at a farther distance from the axis of the filter cartridge 2 than the second insertion tube 6. A detection plate 29 is provided on each fork body in a liftable manner. A detection groove 30 is provided on the detection plate 29. A guiding component for guiding the lifting of the detection plate 29 is provided on the side table 13. When the bracket 15 is closest to the track 12, the guiding component triggers the elastic descent of the detection plate 29. However, only when the first insertion tube 5 is on the side away from the bracket 15, the first insertion tube 5 and the second insertion tube 6 can pass through the detection groove 30 simultaneously. Specifically, convex ridges are provided on the outer wall circumference at the maximum diameter of the upper end of the filter cartridge 2 to increase friction. When the filter cartridge 2 slides on the track 12 and passes by the friction plate 28, the outer wall at its maximum diameter rubs and rolls with the friction plate 28 to adjust the positions of the first insertion tube 5 and the second insertion tube 6 at the upper end of the filter cartridge 2; the rolling that the filter cartridge 2 can trigger when passing by the detection plate 29 is not less than one full rotation; when the detection plate 29 is at the highest position during lifting, the bottom surface thereof is higher than the height of the first insertion tube 5. When the bracket 15 is at the position closest to the track 12, except for the position where the detection groove 30 is provided, the detection plate 29 can cover the range where the first insertion tube 5 and the second insertion tube 6 rotate axially with the filter cartridge 2; one end of the detection groove 30 extends to the end of the detection plate 29 close to the track 12 and is open. The other end of the detection groove 30 corresponds to the rotation range of the second insertion tube 6 when the bracket 15 is at the position closest to the track 12; during the process of the fork body driving the filter cartridge 2 to move, the filter cartridge 2 interacts with the friction plate 28 to trigger self-rotation, driving the first insertion tube 5 and the second insertion tube 6 to rotate. Only when the first insertion tube 5 corresponds to the outer end of the detection groove 30 and the second insertion tube 6 corresponds to the inner end of the detection groove 30, the detection plate 29 is no longer blocked by the first insertion tube 5 or the second insertion tube 6 and can descend, so that the first insertion tube 5 and the second insertion tube 6 can pass through the detection groove 30 simultaneously and limit the continuous self-rotation of the filter cartridge 2; the guiding component limits that only when the bracket 15 is closest to the track 12, the elastic descent of the detection plate 29 is triggered, thereby avoiding false detection.In actual use of the present technical solution, during the process of the fork body engaging the filter cartridge 2, that is, the bracket 15 gradually approaches the track 12, the detection plate 29 is at the highest position close to the top of the filter cartridge 2, and when the bracket 15 reaches the position closest to the track 12, the detection plate 29 triggers the elastic drop. At this time, if the first insertion tube 5 and the second insertion tube 6 on the filter cartridge 2 are in the correct position, the detection plate 29 can be directly dropped to allow the first insertion tube 5 and the second insertion tube 6 to pass through the detection slot 30, and then the filter cartridge 2 will no longer trigger the self-rotation during the movement, and the first insertion tube 5 and the second insertion tube 6 will be kept in the correct position; if the first insertion tube 5 and the second insertion tube 6 on the filter cartridge 2 are not in the correct position, then the filter cartridge 2 will move to the assembly position and contact with the friction plate 2. 8 takes effect and triggers friction rolling, thereby rotating and adjusting the positions of the first cannula 5 and the second cannula 6. Since the first cannula 5 is higher, when the second cannula 6 passes the outer end of the detection slot 30, the first cannula 5 can keep supporting the detection plate 29 and will not get stuck. Since the first cannula 5 is farther from the axis of the filter cartridge 2, the first cannula 5 will not completely pass the inner end of the detection slot 30 and will not get stuck. Only when the first cannula 5 passes the outer end of the detection slot 30, the second cannula 6 also happens to correspond to the inner end of the detection slot 30, thereby triggering the detection plate 29 to move downward, allowing the first cannula 5 and the second cannula 6 to pass through the detection slot 30. Subsequently, the filter cartridge 2 will no longer trigger self-rotation during the movement, keeping the first cannula 5 and the second cannula 6 in the correct position.

[0047] As a preferred technical solution of this embodiment, the guiding component includes a guiding platform 31 fixedly arranged on the side table 13. The part between the guiding platform 31 and the assembly position of the track 12 corresponds. A horizontally extending jump platform 32 is arranged on one side of the guiding platform 31 close to the track 12. A lifting rod 33 is vertically and movably arranged through each fork body. The upper end of the lifting rod 33 is fixedly connected to the detection plate 29. A second elastic member 34 is connected between the bottom of the detection plate 29 and the corresponding fork body. The lower end of the lifting rod 33 is arranged to match the guiding platform 31. Specifically, the extending direction of the guiding platform 31 is parallel to the track 12. When the bracket 15 is far from the track 12, the position of the lifting rod 33 on each fork body is driven to correspond to the guiding platform 31 along the moving track of the positioning trolley 14. One end of the guiding platform 31 close to the top plate 26 is set as a slope, and the other parts of the guiding platform 31 are horizontally arranged, and the height is such that when the lower end of the lifting rod 33 abuts against it, the height of the driving detection plate 29 is not lower than the height of the first insertion tube 5; the jump platform 32 is horizontally arranged, and one end close to the track 12 is open. When the bracket 15 is in the position before the assembly position corresponding to the track 12, when the bracket 15 moves towards the track 12, that is, the lifting rod 33 on each fork body is driven to move from the guiding platform 31 to the jump platform 32. Finally, when the bracket 15 is closest to the track 12, the lower end of the lifting rod 33 disengages from the guiding platform 31, and the second elastic member 34 is triggered to pull the detection plate 29 to maintain a downward trend; subsequently, after the handling and calibration of the filter cartridge 2 are completed at the assembly position, when the bracket 15 moves away from the track 12 again and the positioning trolley 14 also moves back, the lifting rods 33 can be driven to move corresponding to the guiding platform 31 until the lifting rods 33 reach the highest position of the guiding platform 31, and each detection plate 29 is restored to the highest position.
