Specific embodiments

[0018] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the drawings and preferred embodiments to describe in detail the specific embodiments, structures, features and their effects of the present invention as follows.

[0019] As Figure 1-6 shown, a water purifier filter element connection structure provided in this embodiment includes a water purifier connector 1, a sealing disc 2, a docking housing 3, a rotating assembly 4 and a locking assembly 5.

[0020] The water purifier connector 1 is installed on the water purifier. A docking ring 11 is provided at the bottom of the water purifier connector 1, and two water channels 12 communicating with the water path of the water purifier are symmetrically opened at the bottom of the water purifier connector 1. One end of the two water channels 12 is communicated with the bottom of the water purifier connector 1, and the other ends are respectively communicated with the inlet pipe and the outlet pipe of the water purifier.

[0021] The sealing disc 2 is axially rotatably installed within the docking ring 11. Specifically, an annular rotating groove is formed on the inner side of the docking ring 11, and a rotating ring adapted to this rotating groove is provided at the edge of the sealing disc 2. The top surface of the sealing disc 2 abuts against the bottom of the water purifier connector 1. Preferably, a sealing gasket 22 is provided on the top surface of the sealing disc 2 to improve the fitting degree between the sealing disc 2 and the water purifier connector 1. Two butting ports 21 adapted to the water channels 12 are formed on the sealing disc 2. A ring groove 211 is provided at the bottom of the butting port 21. Rotating the sealing disc 2 can align or misalign the two butting ports 21 with the corresponding water channels 12.

[0022] A filter element 31 is installed at the bottom of the docking housing 3. The filter element 31 is fixedly connected to the docking housing 3. The interior of the filter element 31 can adopt a conventional structure, and an inlet and an outlet are respectively provided at the top of the filter element 31. The docking housing 3 can be axially slid into the docking ring 11. Two arc grooves 32 are formed at the top of the docking housing 3. The centers of the two arc grooves 32 are located at the center of the docking housing 3. Docking pipes 33 are respectively inserted into the two arc grooves 32, and the docking pipes 33 can axially slide and move along the arc paths of the arc grooves 32. A clamping ring 331 adapted to the ring groove 211 is provided at the top end of the docking pipe 33. The clamping ring 331 can be snapped into the ring groove 211. The bottom ends of the two docking pipes 33 are respectively communicated with the inlet and the outlet of the filter element 31 through hoses 332. When the docking pipes 33 axially move or move along the arc grooves 32, the hoses 332 can maintain airtight communication with the filter element 31 through deformation. Elastic components 34 are installed on the two docking pipes 33. The elastic components 34 can provide elastic force to eject the docking pipes 33 out of the docking housing 3.

[0023] Specifically, the inner wall of the docking housing 3 is circular. The elastic component 34 includes an annular plate 341. The edge of the annular plate 341 is slidably fitted with the inner wall of the docking housing 3, enabling the annular plate 341 to axially slide along the docking housing 3 and rotate around the axis of the docking housing 3. The annular plate 341 is fixedly connected to the two docking pipes 33. A bottom plate 343 is connected to the bottom of the annular plate 341 through a first spring 342. The bottom plate 343 abuts against the bottom of the docking housing 3. The first spring 342 can provide elastic force to make the annular plate 341 approach the top of the docking housing 3, so as to eject the top end of the docking pipe 33 upward out of the docking housing 3.

[0024] The rotating component 4 can drive the sealing disc 2 to rotate when the docking housing 3 is inserted into the docking ring 11, so as to align the butting ports 21 with the water channels 12.

[0025] In an embodiment, the rotating component 4 includes an adapter plate 41 and a retaining pin 42, as Figure 5As shown, two connecting plates 41 are respectively installed on both sides of the bottom of the sealing disk 2, and the inner sides of the two connecting plates 41 are respectively provided with inclined slide grooves 411. The path of the inclined slide groove 411 is inclined based on the axis of the sealing disk 2, and the bottom end notch of the inclined slide groove 411 is for the bayonet 42 to be inserted. The two bayonet pins 42 are respectively arranged on both sides of the top of the docking shell 3 and can be slidably inserted into the corresponding inclined slide grooves 411. When the docking shell 3 moves toward the docking ring 11, the bayonet pin 42 will extend into the inclined slide groove 411, and as the docking shell 3 continues to move, the inclined slide groove 411 is continuously pushed, thereby causing the sealing disk 2 to rotate, and the two docking ports 21 are aligned with the corresponding waterway 12.

[0026] like Figure 4 As shown, preferably, two correction blocks 111 are provided on the inner wall of the docking ring 11, and a second spring 112 is connected between the two correction blocks 111 and the two connecting plates 41 respectively to provide elastic force to push the connecting plates 41 away, so that when the docking shell 3 is not docked with the docking ring 11, the sealing disk 2 can be rotated to the same position where the docking port 21 and the waterway 12 are staggered. This is the initial position state of the sealing disk 2, which can prevent liquid leakage and facilitate the subsequent docking of the pin 42 with the inclined slide groove 411 and the docking of the retaining ring 331 with the annular groove 211.

[0027] In order to further facilitate docking, preferably, the inner walls on both sides of the docking ring 11 are respectively provided with guide grooves 113, the outer wall of the docking ring 11 is provided with two clamping ports 114 connected with the guide grooves 113, and the two sides of the docking housing 3 are respectively provided with guide sliders 38 adapted to the guide grooves 113. By pushing the guide sliders 38 into the guide grooves 113, the docking housing 3 can maintain non-deflected linear movement in the docking ring 11, and the side wall of the guide slider 38 is provided with an embedding groove 381, and a clamping block 382 is slidably installed in the embedding groove 381. A fourth spring 383 is connected between the clamping block 382 and the inner wall of the embedding groove 381 to provide elastic force to eject the clamping block 382 from the embedding groove 381. It should be noted that when the guide slider 38 is aligned and slides into the guide groove 113, the bayonet 42 can extend into the inclined slide groove 411 in the initial state. By pushing the locking block 382 into the embedding groove 381, the guide slider 38 can continue to slide in the guide groove 113 until the locking block 382 is popped out by the fourth spring 383 and locked in the locking port 114. At this time, the docking shell 3 can be fixed in the docking ring 11, and the rotating component 4 can also rotate the sealing disk 2 until the two docking ports 21 are aligned with the corresponding water channels 12. When the filter element 31 needs to be replaced, the locking block 382 only needs to be pressed to cancel the limit of the docking shell 3 and the docking ring 11.

[0028] When replacing the filter element 31, the old filter element 31 needs to be removed first. By pressing the clamping block 382, the limit between the docking housing 3 and the docking ring 11 is cancelled, and the docking housing 3 is pulled downward. The sealing disc 2 is driven by the rotating assembly 4 to rotate, thereby cutting off the connection between the water channel 12 and the docking port 21. Before the water channel 12 and the docking port 21 are staggered, the docking pipe 33 is kept in contact with the docking port 21 under the push of the elastic assembly 34 until the old filter element 31 is finally removed. Then, take a new filter element 31. When installing the new filter element 31, align the two popped-up docking pipes 33 with the corresponding docking ports 21, make the snap ring 331 snap into the ring groove 211, and then insert the docking housing 3 into the docking ring 11. When the docking housing 3 moves, it pushes the sealing disc 2 to rotate through the rotating assembly 4, so that the docking port 21 is aligned and connected with the corresponding water channel 12, thereby realizing the docking of the water channel 12 and the filter element 31 and completing the replacement of the filter element 31.

[0029] To facilitate the docking of the docking pipe 33 and the docking port 21, preferably, when the docking pipe 33 moves to one end of the arc groove 32, the guiding slider 38 slides into the guiding groove 113, which can make the docking port 21 located on the moving path of the docking pipe 33; when the docking pipe 33 communicates with the corresponding docking port 21 and the water channel 12, the docking pipe 33 will move to the other end of the arc groove 32, which is convenient for alignment.

[0030] It should be noted that in order to prevent the docking pipe 33 from being connected to the non-corresponding water channel 12, an identification mark (not shown in the figure) should be set on the front side of the filter element 31 so that the user can dock correctly. Of course, the two pairs of guiding sliders 38 and guiding grooves 113 can also be set in different shapes and sizes for specific differentiation. Specifically, the correct docking of the filter element 31 can be ensured by a variety of existing technical means, which will not be elaborated here.

[0031] The present invention utilizes the rotating assembly 4 to enable the docking housing 3 to push the sealing disc 2 to rotate during the process of moving into or out of the docking ring 11, so that the docking port 21 can be quickly aligned or staggered with the water channel 12, improving the efficiency of the disassembly, assembly and docking of the filter element 31. By using the elastic assembly 34 that can rotate and move, and the engagement between the snap ring 331 and the ring groove 211, when the sealing disc 2 rotates to gradually connect or cut off the docking port 21 and the water channel 12, the docking pipe 33 can always be kept in contact with the docking port 21 to prevent liquid leakage, which is beneficial to preventing the unpurified sewage from flowing out from the water channel 12 connected to the water inlet end and preventing the contamination of another water channel or the new filter element 31.

[0032] The locking assembly 5 can fix the snap ring 331 in the corresponding ring groove 211.

[0033] In one embodiment, the locking assembly 5 includes a square sliding column 51, a driving gear 52, a first rack 53, a second rack 54 and a driven gear 55. The driving gear 52 is rotatably installed at the center of the sealing disk 2 and a square groove 521 is provided at the bottom thereof. The two first racks 53 are respectively meshed with the two sides of the driving gear 52 and are slidably installed at the bottom of the sealing disk 2. The two first racks 53 are each provided with a second rack 54. The two second racks 54 are respectively facing the two docking ports 21 and the two sides of the second racks 54 are respectively driven and meshed with driven gears 55. The driven gear 55 is rotatably installed at the bottom of the sealing disk 2. The driven gear A clamping rod 551 is provided on 55, and two adjacent clamping rods 551 are respectively located on both sides of the corresponding docking port 21. When the sealing disk 2 is in the initial position, the two adjacent clamping rods 551 are located on the periphery of both sides of the docking port 21. The clamping rod 551 is against the bottom of the sealing disk 2 and its top surface has an elastic cushion layer (not shown in the figure). The square sliding column 51 is slidably penetrated on the top surface of the docking shell 3. The bottom end of the square sliding column 51 is located in the docking shell 3 and is provided with a bottom plate 511. A third spring 512 is connected between the bottom plate 511 and the top wall of the docking shell 3 to provide an elastic force to pop the docking shell 3 out of the top of the docking shell 3. When the docking shell 3 is inserted into the docking ring 11, the square slide post 51 is pushed by the third spring 512 and inserted into the square groove 521 of the driving gear 52. Since the docking shell 3 will not rotate when it moves into the docking ring 11, the square slide post 51 will clamp the driving gear 52 to prevent it from rotating. As the docking shell 3 moves, the sealing disk 2 will rotate under the drive of the rotating component 4, so that the sealing disk 2 will rotate relative to the driving gear 52, and the two first racks 53 will mesh with the driving gear 52 to move and control the corresponding second racks 54 to move, thereby driving each driven gear 55 to rotate, so that the clamping rods 551 on both sides of the docking port 21 are close to each other and clamped on both sides of the corresponding docking pipe 33, and at the same time, the upper snap ring 331 is pressed against the annular groove 211, and the driving gear 52 is limited by the square slide post 51, and the rotation of the sealing disk 2 is used to drive and control the locking component 5, so as to realize automatic fixation of the snap ring 331, improve the fit between the docking pipe 33 and the docking port 21, and further prevent liquid leakage. When the old filter element 31 is removed, as the docking shell 3 is moved out, the sealing disk 2 rotates with the control of the rotating component 4, and the square slide column 51 is kept in the square groove 521 under the push of the third spring 512, so that the clamping rod 551 can be controlled to move away from the docking tube 33 through the locking component 5 to automatically cancel the fixation of the retaining ring 331.

[0034] Preferably, the clamping rod 551 is in an arc shape, and two adjacent clamping rods 551 can form a closed circular ring when close to each other, and the inner diameter of the circular ring is adapted to the outer diameter of the butt joint pipe 33 to improve the clamping degree of the butt joint pipe 33.

[0035] In one embodiment, a water absorption chamber 35 is provided on the inner cavity top wall of the docking housing 3, wrapped around a square sliding column 51, and the edge of the bottom film 511 is in contact with the inner wall of the water absorption chamber 35. On both sides of the bottom of the water absorption chamber 35, water suction pipes 36 are respectively provided. Leakage openings 37 are respectively formed beside the two docking pipes 33 at the top of the docking housing 3, and the two water suction pipes 36 are respectively connected to the two leakage openings 37. When the docking housing 3 is moved into the docking ring 11, the square sliding column 51 will be pressed into the docking housing 3, causing the bottom film 511 to move towards the bottom of the water absorption chamber 35, and pushing the gas in the water absorption chamber 35 out of the leakage opening 37 through the water suction pipe 36. When the filter element 31 needs to be removed when its service life expires, as the docking housing 3 is moved out, the square sliding column 51 will be pushed out of the docking housing 3 under the elastic force of the third spring 512, so that the bottom film 511 moves upward above the water absorption chamber 35, and then a negative pressure attraction is formed below the interior of the water absorption chamber 35. When liquid leaks unexpectedly at the docking port 21, the liquid can be immediately absorbed by the leakage opening 37, preventing the accumulation of liquid and reducing the pollution risk of the connection structure.

[0036] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
