It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0046] In the description of the present invention, "a plurality" means more than two. If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0048] Refer to Figures 1 to 5 , a filter element replacement device according to an embodiment of the present invention includes:

[0049] Filter element 200;

[0050] Frame 100, having a receiving cavity 120 suitable for installing the filter element 200, and the receiving cavity 120 has an open installation opening;

[0051] The locking mechanism 500 and the control part 150 are both arranged on the frame 100. The control part 150 is in transmission connection with the locking mechanism 500. A mating part 220 is arranged on the filter element 200. When the filter element 200 moves along the direction from the installation opening into the accommodation cavity 120, it can drive the mating part 220 to be connected with the locking mechanism 500 to lock the installation position of the filter element 200. Applying force to the control part 150 can drive the locking mechanism 500 to be separated from the mating part 220 to allow the filter element 200 to be removed from the accommodation cavity 120.

[0052] It can be understood that when the filter element 200 needs to be installed, one end of the mating part 220 of the filter element 200 can be inserted into the accommodation cavity 120. As the filter element 200 continues to be inserted, the mating part 220 on the filter element 200 is connected to the locking mechanism 500, so that the filter element 200 is locked in the installation position, and thus the installation of the filter element 200 is completed. When the filter element 200 needs to be disassembled, the user only needs to apply force to the control part 150 to separate the mating part 220 on the filter element 200 from the locking mechanism 500, and the user can remove the filter element 200 from the accommodation cavity 120, and thus the disassembly of the filter element 200 is completed. In this filter element replacement device, the user only needs to insert the filter element 200 into the accommodation cavity 120 to complete the installation of the filter element 200; and only by applying force to the control part 150, the disassembly of the filter element 200 can be quickly completed, simplifying the installation and disassembly steps of the filter element 200, and thus being beneficial to improving the convenience of the user to replace the filter element 200.

[0053] Reference Figure 4 、 Figure 5 、 Figure 10 and Figure 11 Furthermore, the filter element replacement device further includes an elastic sealing mechanism 400. A waterway joint 300 is arranged on the frame 100. A swivel joint 210 is provided at one end of the filter element 200. The elastic sealing mechanism 400 is arranged in the swivel joint 210. When the filter element 200 moves along the direction from the installation opening into the accommodation cavity 120 to the locking position, the swivel joint 210 is in mating connection with the waterway joint 300, and the elastic sealing mechanism 400 is compressed and the swivel joint 210 is opened. When applying force to the control part 150 to drive the locking mechanism 500 to be separated from the mating part 220, the elastic sealing mechanism 400 is restored and pushes the filter element 200, so that the filter element 200 is removed from the accommodation cavity 120, and the elastic sealing mechanism 400 reseals the swivel joint 210. Specifically, the mating part 220 is arranged on the swivel joint 210.

[0054] It can be understood that when the filter element 200 needs to be installed, one end of the mating portion 220 of the filter element 200 can be inserted into the receiving cavity 120. As the filter element 200 is continuously inserted, the mating portion 220 on the filter element 200 is connected to the locking mechanism 500, so that the filter element 200 is locked in the installation position. At this time, the adapter 210 at the lower end of the filter element 200 is matingly connected with the waterway connector 300 on the waterway connector 300, the elastic sealing mechanism 400 is compressed, and the adapter 210 is opened by the elastic sealing mechanism 400, so that the inner cavity of the filter element 200 is communicated with the waterway on the waterway connector 300 through the adapter 210 and the waterway connector 300, thus completing the installation of the filter element 200. When the filter element 200 needs to be removed, the user only needs to apply force to the control part 150 to separate the mating portion 220 on the filter element 200 from the locking mechanism 500. After the mating portion 220 on the filter element 200 is separated from the locking mechanism 500, the elastic sealing mechanism 400 begins to recover. The elastic sealing mechanism 400 in the recovery process can push the filter element 200, so that the filter element 200 begins to move away from the waterway connector 300. When the elastic sealing mechanism 400 is completely recovered, the elastic sealing mechanism 400 reseals the adapter 210, and under the pushing force of the elastic sealing mechanism 400, the end of the filter element 200 away from the mating portion 220 pops out of the receiving cavity 120. At this time, the user can hold the end of the filter element 200 away from the mating portion 220 and pull out the entire filter element 200 from the receiving cavity 120, thus completing the removal of the filter element 200.

[0055] It should be explained that the waterway connector 300 is a common component in a water purifier for controlling the flow direction and distribution of water. A channel for water flow, that is, a waterway, is provided in the waterway connector 300. Water flows into the filter element 200 through the waterway connector 300, and the water in the filter element 200 also flows into other components through the waterway connector 300. In the embodiment of the present utility model, after the adapter 210 and the waterway connector 300 are matingly connected, the inner cavity of the filter element 200 can be communicated with the channel on the waterway connector 300 through the adapter 210 and the waterway connector 300. At this time, the filter element 200 can normally perform the filtering work, which will not be further described here.

[0056] Reference Figures 1 to 3 , in the embodiment of the present utility model, the first end of the filter element 200 is the lower end of the filter element 200, and the second end of the filter element 200 is the upper end of the filter element 200. The first end of the frame 100 is the lower end of the frame 100, and the second end of the frame 100 is the upper end of the frame 100.

[0057] It can be seen that in the embodiment of the present utility model, the elastic sealing mechanism 400 not only provides a force for the filter element 200 to move away from the waterway joint 300, but also seals the adapter 210. When it is necessary to disassemble the filter element 200, the user only needs to apply force to the control part 150 to separate the mating part 220 of the filter element 200 from the locking mechanism 500. After the locking force of the locking mechanism 500 on the mating part 220 of the filter element 200 is lost, the elastic sealing mechanism 400 begins to recover. When the elastic sealing mechanism 400 is completely recovered, the elastic sealing mechanism 400 reseals the adapter 210. Under the pushing force of the elastic sealing mechanism 400, the second end of the filter element 200 extends out of the accommodating cavity 120. When the user holds the second end of the filter element 200 and pulls the filter element 200 out of the accommodating cavity 120, since the elastic sealing mechanism 400 reseals the adapter 210, the water in the filter element 200 will not flow into the accommodating cavity 120 through the adapter 210, avoiding the pollution of the accommodating cavity 120 by the water in the filter element 200 and being beneficial to ensuring the cleanliness of the water purifier.

[0058] In the embodiment of the present utility model, the frame 100 is provided with a panel 110, and the panel 110 can be installed on the outer shell of the water purifier. The control part 150 can be a button, and the button is movably connected to the panel 110, so that the user can directly see the button on the panel 110, so that the user can directly apply force to the button.

[0059] Reference Figures 10 to 12, the adapter 210 is provided with a plurality of flow channels 211 for water supply to flow, and the plurality of flow channels 211 are all communicated with the inner cavity of the filter element 200. The elastic sealing mechanism 400 includes a plurality of elastic sealing components 410, and the plurality of elastic sealing components 410 are respectively arranged in the plurality of flow channels 211. The plurality of elastic sealing components 410 can respectively seal one end of the plurality of flow channels 211 away from the filter element 200. The waterway joint 300 includes a plurality of adapter pipes 310, and the plurality of adapter pipes 310 can respectively be inserted into the plurality of flow channels 211 and respectively push against the plurality of elastic sealing components 410, so that the plurality of elastic sealing components 410 are compressed and the one end of the plurality of flow channels 211 away from the filter element 200 is opened. Specifically, the elastic sealing component 410 includes a second elastic member 411, a sealing rubber ring 412 and a seal 413. The second elastic member 411, the sealing rubber ring 412 and the seal 413 are all arranged in the flow channel 211. The sealing rubber ring 412 is arranged on the inner wall of the flow channel 211 away from the filter element 200. One end of the second elastic member 411 is connected to the seal 413, and the other end of the second elastic member 411 is connected to the inner wall of the flow channel 211 close to the filter element 200. The second elastic member 411 can force the seal 413 to press against the sealing rubber ring 412, so that the seal 413 seals the one end of the flow channel 211 away from the filter element 200. The gap between the seal 413 and the inner wall of the flow channel 211 is used for water supply to flow. The adapter pipe 310 can push against the seal 413 and insert into the sealing rubber ring 412 and the flow channel 211, so that the second elastic member 411 is compressed and the seal 413 opens the one end of the flow channel 211 away from the filter element 200. The second elastic member 411 includes a second spring. One end of the second spring is connected to the seal 413, and the other end of the second spring is connected to the inner wall of the flow channel 211 close to the filter element 200. The second spring can force the seal 413 to press against the sealing rubber ring 412.

[0060] It can be understood that when the filter element 200 is in an uninstalled state, under the urging of a plurality of second elastic members 411, a plurality of seals 413 can respectively press against a plurality of sealing rubber rings 412, so that the first ends of the plurality of flow channels 211 away from the filter element 200 are respectively sealed by the plurality of seals 413. When the filter element 200 needs to be installed, the operator can align the first end of the filter element 200 with the receiving cavity 120 and insert the filter element 200 into the receiving cavity 120. During the process of inserting the filter element 200 in the direction towards the water connection joint 300, a plurality of adapter pipes 310 can respectively be inserted into a plurality of sealing rubber rings 412 and a plurality of flow channels 211. After the adapter pipes 310 are inserted into the sealing rubber rings 412, the sealing rubber rings 412 will deform and press against the outer walls of the adapter pipes 310, that is, the sealing rubber rings 412 seal the gaps between the outer walls of the adapter pipes 310 and the sealing rubber rings 412. As the filter element 200 continues to be inserted, a plurality of adapter pipes 310 can respectively push against a plurality of seals 413, so that a plurality of second elastic members 411 start to be compressed. At the same time, a plurality of seals 413 start to respectively move away from the sealing rubber rings 412, so that the first ends of the plurality of flow channels 211 away from the filter element 200 are opened. At this time, the plurality of flow channels 211 are respectively communicated with the plurality of adapter pipes 310. When the filter element 200 moves into place, that is, when the filter element 200 moves to the installation position, the locking assembly locks the filter element 200, so that the filter element 200 is locked and fixed at the installation position to complete the installation of the filter element 200.

[0061] When the user needs to remove the filter element 200 from the receiving cavity 120, the user applies force to the control part 150, so that the control part 150 drives the locking mechanism 500 to separate from the filter element 200. After the filter element 200 loses the locking force, a plurality of second elastic members 411 in a compressed state start to recover, that is, a plurality of second elastic members 411 start to extend. Since one ends of a plurality of second elastic members 411 are respectively connected to a plurality of seals 413, and a plurality of seals 413 respectively abut against a plurality of adapter pipes 310, a plurality of second elastic members 411 will extend in a direction away from the water connection joint 300, that is, a plurality of second elastic members 411 in the recovery process can push against the filter element 200 in a direction away from the water connection joint 300. When a plurality of second elastic members 411 are completely recovered, that is, when the second elastic members 411 return to the state when the filter element 200 is in an uninstalled state, the second end of the filter element 200 extends out of the receiving cavity 120, and a plurality of adapter pipes 310 are respectively withdrawn from a plurality of flow channels 211. Under the urging of a plurality of second elastic members 411, a plurality of seals 413 respectively press against a plurality of sealing rubber rings 412 again, so that the first ends of the plurality of flow channels 211 away from the filter element 200 are respectively re-sealed by the plurality of seals 413. Finally, the user removes the filter element 200 from the receiving cavity 120 to complete the disassembly of the filter element 200.

[0062] Further, after multiple second elastic members 411 are fully restored, multiple adapter pipes 310 are respectively withdrawn from multiple flow channels 211. At the same time, multiple seals 413 reseal multiple flow channels 211. And during the process of the filter element 200 popping out, the sealing rubber ring 412 always keeps pressing against the adapter pipe 310, preventing the water in the filter element 200 from flowing into the accommodation cavity 120 during the process of the filter element 200 popping out, thereby avoiding the contamination of the accommodation cavity 120 and being beneficial to ensuring the cleanliness of the water purifier.

[0063] It should be explained that after the adapter pipe 310 abuts against the seal 413, there is a gap between the adapter pipe 310 and the seal 413, that is, water can flow in the gap between the adapter pipe 310 and the seal 413, so that water can flow from the flow channel 211 into the adapter pipe 310, and the water in the adapter pipe 310 can also flow into the flow channel 211. In the embodiment of the present invention, referring to the figure, the number of both the flow channels 211 and the adapter pipes 310 is three. The leftmost flow channel 211 and the adapter pipe 310 in the figure are the water inlet flow channel 211 and the water inlet adapter pipe 310 respectively, and the two flow channels 211 and the adapter pipes 310 on the right are the water outlet flow channel 211 and the water outlet adapter pipe 310 respectively. The water inlet channel on the water connection joint 300 is communicated with the adapter pipe 310, so that the water to be filtered flows into the water inlet adapter pipe 310 through the water inlet channel on the water connection joint 300 and then into the water inlet flow channel 211. At this time, the water to be filtered can flow into the interior of the filter element 200, and the filtering structure inside the filter element 200 can filter the water. The water outlet adapter pipe 310 is communicated with the water outlet channel on the water connection joint 300. After the water filtration is completed, the water flows into the water outlet channel on the water connection joint 300 through the water outlet flow channel 211 and the water outlet adapter pipe 310. Finally, the filtered water can be supplied to the user through accessories such as water pipes to complete the filtration. The filter element 200 is a common water filtration component and will not be further elaborated here.

[0064] Specifically, referring to Figure 13 and Figure 14 , the water connection joint 300 further includes multiple special-shaped flow guiding members 320. The multiple special-shaped flow guiding members 320 are respectively inserted into the multiple adapter pipes 310. The multiple special-shaped flow guiding members 320 are all used to abut against the multiple seals 413, and the gap between the special-shaped flow guiding member 320 and the inner wall of the adapter pipe 310 is used for water to flow. The special-shaped flow guiding member 320 is a cross-shaped flow guiding member. A part of the structure of the special-shaped flow guiding member 320 is arranged inside the adapter pipe 310, and another part of the structure of the special-shaped flow guiding member 320 extends out of the adapter pipe 310. The other part of the structure of the special-shaped flow guiding member 320 is used to abut against the seal 413, that is, the adapter pipe 310 pushes the seal 413 through the special-shaped flow guiding member 320. The gap between the special-shaped flow guiding member 320 and the inner wall of the adapter pipe 310 is used for water to flow, so that water can flow from the flow channel 211 into the adapter pipe 310 or from the adapter pipe 310 into the flow channel 211.

[0065] In the embodiment of the utility model, the diameter of the sealing member 413 is smaller than the inner diameter of the flow channel 211 , so that water can flow smoothly in the gap between the sealing member 413 and the inner wall of the flow channel 211 .

[0066] refer to Figure 5 and Figure 6 The outer wall of the transfer tube 310 toward the second end of the frame 100 gradually narrows toward the second end of the frame 100, so that the transfer tube 310 can be inserted into the sealing rubber ring 412. It can be understood that the outer wall of the transfer tube 310 gradually narrows toward the second end of the frame 100, so that the transfer tube 310 can be smoothly inserted into the sealing rubber ring 412 and the flow channel 211.

[0067] refer to Figures 7 to 9 The locking mechanism 500 includes a locking assembly and a first reset assembly 550. The locking assembly is movably arranged on the frame 100 and can move between a first position and a second position relative to the frame 100. When the locking assembly is in the first position, it is suitable for connecting with the matching portion 220 to lock the installation position of the filter element 200. When the locking assembly is in the second position, it is suitable for separating from the matching portion 220 to allow the filter element 200 to escape from the accommodating cavity 120. The first reset assembly 550 is arranged on the frame 100 and often pushes the locking assembly to move from the second position to the first position.

[0068] Specifically, the locking assembly includes a first swing arm 530 and a second swing arm 540 arranged side by side on the frame 100, and the first reset assembly 550 includes a first elastic member. The first end of the first swing arm 530 and the first end of the second swing arm 540 are both rotatably connected to the frame 100, and the second end of the first swing arm 530 and the second end of the second swing arm 540 are away from each other so that the locking assembly is in the second position. The first elastic member is respectively connected to the second end of the first swing arm 530 and the second end of the second swing arm 540, and the first elastic member is configured to generate an elastic force to drive the second end of the first swing arm 530 and the second end of the second swing arm 540 to approach each other to push the locking assembly to move from the second position to the first position.

[0069] Specifically, a first locking block 533 is provided on one side of the first swing arm 530 close to the second swing arm 540, and a second locking block 541 is provided on one side of the second swing arm 540 close to the first swing arm 530. The engaging portion 220 includes a rib 221 and a groove 222 provided on the filter element 200. When the filter element 200 moves along the direction from the installation opening into the accommodation cavity 120, the rib 221 abuts against the first locking block 533 and the second locking block 541 respectively to push the second ends of the first swing arm 530 and the second swing arm 540 away from each other, and the first elastic member drives the second ends of the first swing arm 530 and the second swing arm 540 to approach each other so that both the first locking block 533 and the second locking block 541 are snapped into the groove 222.

[0070] It should be noted that when the first swing arm 530 and the second swing arm 540 move away from each other, the locking assembly can be in the second position, and when the first swing arm 530 and the second swing arm 540 approach each other, the locking assembly can be in the first position. It can be understood that when installing the filter element 200, the operator can align the first end of the filter element 200 with the accommodation cavity 120 and insert the filter element 200 into the accommodation cavity 120. During the process of inserting the filter element 200 in the direction towards the water connection joint 300, the rib 221 on the outer wall of the adapter 210 can abut against the first locking block 533 and the second locking block 541 respectively. As the filter element 200 continues to be inserted, since the first ends of the first swing arm 530 and the second swing arm 540 are rotatably connected to the frame 100, at this time, under the pushing action of the rib 221, the first swing arm 530 and the second swing arm 540 start to rotate, causing the second ends of the first swing arm 530 and the second swing arm 540 and the first locking block 533 and the second locking block 541 to move away from each other. As the filter element 200 continues to be inserted, the rib 221 slides past the first locking block 533 and the second locking block 541 respectively. At this time, the first elastic member drives the second ends of the first swing arm 530 and the second swing arm 540 to approach each other, causing the first locking block 533 and the second locking block 541 to approach each other, so that both the first locking block 533 and the second locking block 541 can be snapped into the groove 222, thereby locking and fixing the filter element 200 at the installation position by the first locking block 533 and the second locking block 541. When the filter element 200 is in the installation position, the adapter 210 is cooperatively connected with the water connection joint 300.

[0071] Reference Figure 1 and Figure 7 The filter element replacement device further includes a transmission rod 130 provided on the frame 100. One end of the transmission rod 130 is connected to the control portion 150, and a conical portion 131 is provided at the other end of the transmission rod 130. By applying force to the control portion 150, the conical portion 131 moves along the direction from the installation opening into the accommodation cavity 120 and drives the second ends of the first swing arm 530 and the second swing arm 540 to move away from each other, so that both the first locking block 533 and the second locking block 541 are separated from the groove 222.

[0072] It can be understood that the conical part 131 is in transmission connection with the control part 150 through the transmission rod 130. When the control part 150 is pressed, that is, when a force is applied, the conical part 131 can squeeze the second ends of the first swing arm 530 and the second swing arm 540. Therefore, under the expansion action of the conical part 131, the second ends of the first swing arm 530 and the second swing arm 540 begin to move away from each other, that is, the first buckle 533 and the second buckle 541 move away from each other, and further the first buckle 533 and the second buckle 541 are separated from the groove 222. At this time, the second end of the filter element 200 pops out from the accommodation cavity 120, and the disassembly of the filter element 200 can be completed. After the user releases the control part 150, under the action of the first reset assembly 550, the second ends of the first swing arm 530 and the second swing arm 540 approach each other, and the conical part 131 moves and resets in a direction away from the water connection joint 300, and further the control part 150 resets. The first reset assembly 550 includes a tension spring, and the two ends of the tension spring are respectively connected to the second ends of the first swing arm 530 and the second swing arm 540.

[0073] As an embodiment of the present utility model, limiting grooves 532 are respectively provided on the second ends of the first swing arm 530 and the second swing arm 540, and one end of the conical part 131 away from the panel 110 is arranged in the two limiting grooves 532. It can be understood that the conical part 131 is arranged in the two limiting grooves 532, and the inner walls of the two limiting grooves 532 can play a role in limiting the conical part 131, avoiding the shaking of the conical part 131 during the process of squeezing the first swing arm 530 and the second swing arm 540, and improving the stability of the process of expanding the second ends of the first swing arm 530 and the second swing arm 540. Specifically, the control part 150 further includes an elastic buckle 140, the elastic buckle 140 is arranged on the frame 100, the transmission rod 130 is buckled on the elastic buckle 140, and the elastic buckle 140 can prevent the transmission rod 130 from shaking during the transmission process.

[0074] Reference Figure 7 and Figure 9, the locking mechanism 500 further includes a base 520 and two mounting posts 522. A first avoidance hole 521 is formed in the base 520 for the adapter 210 to extend into. The base 520 is connected to the frame 100. The first ends of the first swing arm 530 and the second swing arm 540 are rotatably connected to the base 520. The two mounting posts 522 are both provided on the base 520. Mounting holes 531 are formed in the first ends of the first swing arm 530 and the second swing arm 540. The two mounting posts 522 respectively pass through the two mounting holes 531 so that the second ends of the first swing arm 530 and the second swing arm 540 can rotate around the two mounting posts 522 respectively. The locking mechanism 500 further includes an upper cover 510. The upper cover 510 is connected to the base 520. A second avoidance hole 511 is formed in the upper cover 510. The second avoidance hole 511 is communicated with the first avoidance hole 521 and is used for the adapter 210 on the filter element 200 to extend into.

[0075] When the filter element 200 needs to be disassembled, the user operates the control part 150. The control part 150 can drive the second ends of the first swing arm 530 and the second swing arm 540 to move away from each other, so that the first buckle 533 and the second buckle 541 move away from each other. At this time, the groove 222 on the adapter 210 is separated from the first buckle 533 and the second buckle 541. After the adapter 210 loses the buckling force of the first buckle 533 and the second buckle 541, the filter element 200 starts to bounce under the pushing action of the elastic sealing mechanism 400, thereby completing the disassembly of the filter element 200.

[0076] It should be noted that under the action of a plurality of second elastic members 411, the first buckle 533 and the second buckle 541 can respectively press and fix on the convex strip 221, avoiding the shaking of the filter element 200 and being beneficial to improving the stability of the connection of the filter element 200.

[0077] As an embodiment of the present utility model, a first guiding surface 534 is provided on one side of the first buckle 533 close to the second buckle 541, and a second guiding surface 223 corresponding to the first guiding surface 534 is provided on the convex strip 221. A third guiding surface is provided on one side of the second buckle 541 close to the first buckle 533. There are two second guiding surfaces 223 on the convex strip 221, and the two second guiding surfaces 223 respectively correspond to the first guiding surface 534 and the third guiding surface. The two second guiding surfaces 223 can respectively abut against the first guiding surface 534 and the third guiding surface, making the insertion process of the filter element 200 smoother and being beneficial to improving the convenience of the user to install the filter element 200, which will not be further elaborated here.

[0078] As an embodiment of the present utility model, a limiting hole 121 is provided on the bottom wall of the accommodation cavity 120. The shape of the limiting hole 121 is the same as the cross-sectional shape of the adapter 210. The inner wall of the limiting hole 121 can limit the adapter 210 on the filter element 200, so that the adapter 210 can extend into the second avoidance hole 511 and the first avoidance hole 521 in a correct posture, and further enable the adapter 210 to be smoothly connected with the water path joint 300. A holding portion 230 is further provided at the second end of the filter element 200. After the filter element 200 is inserted into the accommodation cavity 120, the user can hold the holding portion 230 to drive the filter element 200 to rotate, so that the adapter 210 on the filter element 200 can be aligned with the limiting hole 121, so that the filter element 200 can be smoothly inserted into the installation position, and further enable the adapter 210 to be smoothly connected with the water path joint 300.

[0079] The present utility model also proposes a water purifier, which includes a housing and a filter element replacement device. The filter element replacement device is arranged on the housing. A panel 110 is arranged on the housing. The beneficial effects of this water purifier will not be further described here.
