[0047] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field 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 According to an embodiment of the present invention, a filter element replacement device comprises:

[0049] Filter element 200;

[0050] The frame 100 has 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 operating part 150 are both arranged on the frame 100. The operating part 150 is connected to the locking mechanism 500 in transmission. A matching part 220 is arranged on the filter element 200. The filter element 200 moves in the direction from the installation port into the accommodating cavity 120 to drive the matching part 220 to connect with the locking mechanism 500 to lock the installation position of the filter element 200. Applying force to the operating part 150 can drive the locking mechanism 500 to separate from the matching part 220 to allow the filter element 200 to escape from the accommodating cavity 120.

[0052] It is understandable that when the filter element 200 needs to be installed, one end of the matching portion 220 of the filter element 200 can be inserted into the accommodating chamber 120. As the filter element 200 is continuously inserted, the matching portion 220 on the filter element 200 is connected with the locking mechanism 500, so that the filter element 200 is locked in the installation position, thereby 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 portion 150 so that the matching portion 220 on the filter element 200 is separated from the locking mechanism 500, and the user can remove the filter element 200 from the accommodating chamber 120, thereby completing the removal of the filter element 200. In the filter element replacement device, the user only needs to insert the filter element 200 into the accommodating chamber 120 to complete the installation of the filter element 200; and only needs to apply force to the control portion 150 to quickly complete the removal of the filter element 200, which simplifies the installation and removal steps of the filter element 200, thereby facilitating the convenience of the user to replace the filter element 200.

[0053] refer to Figure 4 , Figure 5 , Fig.10 and Fig.11 The filter element replacement device further includes an elastic sealing mechanism 400. A water channel joint 300 is provided on the frame 100. An adapter 210 is provided at one end of the filter element 200. The elastic sealing mechanism 400 is provided in the adapter 210. When the filter element 200 moves from the installation port to the accommodating cavity 120 to the locking position, the adapter 210 is matched and connected with the water channel joint 300, and the elastic sealing mechanism 400 is compressed and the adapter 210 is opened. When a force is applied to the control part 150 to drive the locking mechanism 500 to separate from the matching part 220, the elastic sealing mechanism 400 is restored and pushes the filter element 200, so that the filter element 200 escapes from the accommodating cavity 120, and the elastic sealing mechanism 400 re-seals the adapter 210. Specifically, the matching part 220 is provided on the adapter 210.

[0054] It is understandable that when the filter element 200 needs to be installed, one end of the matching portion 220 of the filter element 200 can be inserted into the accommodating cavity 120. As the filter element 200 is continuously inserted, the matching portion 220 on the filter element 200 is connected with the locking mechanism 500, so that the filter element 200 is locked in the installation position. At this time, the adapter 210 on the lower end of the filter element 200 is matched and 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 connected with the waterway on the waterway connector 300 through the adapter 210 and the waterway connector 300, thereby 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 matching portion 220 on the filter element 200 from the locking mechanism 500. After the matching portion 220 on the filter element 200 is separated from the locking mechanism 500, the elastic sealing mechanism 400 begins to recover, and 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 water channel joint 300. When the elastic sealing mechanism 400 is completely recovered, the elastic sealing mechanism 400 re-seals the adapter 210, and under the pushing force of the elastic sealing mechanism 400, the end of the filter element 200 away from the matching portion 220 pops out from the accommodating cavity 120. At this time, the user can hold the end of the filter element 200 away from the matching portion 220 and pull the filter element 200 out of the accommodating cavity 120, thereby 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, i.e., 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 an embodiment of the present invention, after the adapter 210 and the waterway connector 300 are connected, the inner cavity of the filter element 200 can be connected to the channel on the waterway connector 300 through the adapter 210 and the waterway connector 300. At this time, the filter element 200 can perform filtering work normally, which will not be further described here.

[0056] refer to Figures 1 to 3 In the embodiment of the present invention, 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 invention, the elastic sealing mechanism 400 not only serves to provide a force for the filter element 200 to be away from the water channel connector 300, but also serves to seal the adapter 210. When the filter element 200 needs to be disassembled, the user only needs to apply force to the operating part 150 to separate the matching part 220 of the filter element 200 from the locking mechanism 500. After the matching part 220 of the filter element 200 loses the locking force of the locking mechanism 500, the elastic sealing mechanism 400 begins to recover. When the elastic sealing mechanism 400 is fully recovered, the elastic sealing mechanism 400 re-seals the adapter 210. Under the top thrust of the elastic sealing mechanism 400, the second end of the filter element 200 extends out from 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 chamber 120, the elastic sealing mechanism 400 re-seals the adapter 210. Therefore, the water in the filter element 200 will not flow into the accommodating chamber 120 through the adapter 210, thereby preventing the water in the filter element 200 from contaminating the accommodating chamber 120, which is beneficial to ensuring the cleanliness of the water purifier.

[0058] In the embodiment of the present invention, the frame 100 has a panel 110, and the panel 110 can be installed on the housing of the water purifier. The control unit 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] refer to Figures 10 to 12The adapter 210 is provided with a plurality of flow channels 211 for water flow, and the plurality of flow channels 211 are all connected to 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 water channel connector 300 includes a plurality of adapter tubes 310, and the plurality of adapter tubes 310 can respectively be inserted into the plurality of flow channels 211 and respectively push the plurality of elastic sealing components 410 so that the plurality of elastic sealing components 410 are compressed and open one end of the plurality of flow channels 211 away from the filter element 200. Specifically, the elastic sealing assembly 410 includes a second elastic member 411, a sealing rubber ring 412 and a sealing member 413. The second elastic member 411, the sealing rubber ring 412 and the sealing member 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 sealing member 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 elastic member 411 can force the seal 413 to press against the sealing rubber ring 412, so that the seal 413 seals the end of the flow channel 211 away from the filter element 200, and the gap between the seal 413 and the inner wall of the flow channel 211 is used for water flow. The transfer tube 310 can push the seal 413 and insert it 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 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 is understandable that when the filter element 200 is not installed, under the compulsion of the second elastic members 411, the multiple seals 413 can be pressed against the multiple sealing rubber rings 412 respectively, so that the first ends of the multiple flow channels 211 away from the filter element 200 are sealed by the multiple seals 413 respectively. When the filter element 200 needs to be installed, the operator can align the first end of the filter element 200 with the accommodating cavity 120 and insert the filter element 200 into the accommodating cavity 120. In the process of inserting the filter element 200 toward the water channel joint 300, the multiple transfer tubes 310 can be inserted into the multiple sealing rubber rings 412 and the multiple flow channels 211 respectively. After the transfer tube 310 is inserted into the sealing rubber ring 412, the sealing rubber ring 412 will be deformed and pressed against the outer wall of the transfer tube 310, that is, the sealing rubber ring 412 seals the gap between the outer wall of the transfer tube 310 and the sealing rubber ring 412. As the filter element 200 is continuously inserted, the multiple transfer tubes 310 can push the multiple seals 413 respectively, so that the multiple second elastic members 411 begin to compress. At the same time, the multiple seals 413 begin to move away from the sealing rubber ring 412 respectively, so that the multiple flow channels 211 away from the first end of the filter element 200 are opened. At this time, the multiple flow channels 211 are respectively connected with the multiple transfer tubes 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 take the filter element 200 out of the accommodating chamber 120, the user applies force to the operating part 150, so that the operating part 150 drives the locking mechanism 500 to separate from the filter element 200. After the filter element 200 loses the locking force, the plurality of second elastic members 411 in the compressed state begin to recover, that is, the plurality of second elastic members 411 begin to stretch. Since one end of the plurality of second elastic members 411 is respectively connected to the plurality of sealing members 413, and the plurality of sealing members 413 are respectively in contact with the plurality of transfer tubes 310, the plurality of second elastic members 411 will stretch in the direction away from the waterway connector 300, that is, the plurality of second elastic members 411 in the recovery process can push the filter element 200 in the direction away from the waterway connector 300. When the plurality of second elastic members 411 are completely recovered, that is, the second elastic members 411 are restored to the state where the filter element 200 is not installed, the second end of the filter element 200 extends out from the accommodating chamber 120, and the plurality of transfer tubes 310 are respectively drawn out from the plurality of flow channels 211. Under the compulsion of the second elastic members 411, the seals 413 are respectively pressed against the sealing rubber rings 412, so that the first ends of the flow channels 211 away from the filter element 200 are respectively resealed by the seals 413. Finally, the user takes the filter element 200 out of the accommodating chamber 120 to complete the disassembly of the filter element 200.

[0062] Furthermore, when the plurality of second elastic members 411 are fully restored, the plurality of transfer tubes 310 are respectively drawn out from the plurality of flow channels 211, and at the same time, the plurality of sealing members 413 reseal the plurality of flow channels 211. In addition, during the process of the filter element 200 being ejected, the sealing rubber ring 412 always maintains abutment against the transfer tube 310, thereby preventing the water in the filter element 200 from flowing into the accommodating chamber 120 during the process of the filter element 200 being ejected, thereby preventing the accommodating chamber 120 from being contaminated, and thus facilitating the cleanliness of the water purifier.

[0063] It should be explained that after the transfer tube 310 abuts against the seal 413, there is a gap between the transfer tube 310 and the seal 413, that is, water can flow in the gap between the transfer tube 310 and the seal 413, so that water can flow from the flow channel 211 into the transfer tube 310, and water in the transfer tube 310 can also flow into the flow channel 211. In the embodiment of the present invention, referring to the figure, there are three flow channels 211 and transfer tubes 310, the flow channel 211 and transfer tube 310 on the far left in the figure are respectively the water inlet flow channel 211 and the water inlet transfer tube 310, and the two flow channels 211 and transfer tubes 310 on the right are respectively the water outlet flow channel 211 and the water outlet transfer tube 310. The water inlet channel on the waterway connector 300 is connected to the transfer tube 310, so that the water to be filtered flows into the water inlet transfer tube 310 through the water inlet channel on the waterway connector 300, and then flows into the water inlet channel 211. At this time, the water to be filtered can flow into the interior of the filter element 200, and the structure for filtering inside the filter element 200 can filter the water. The water outlet transfer tube 310 is connected to the water outlet channel on the waterway connector 300. After the water is filtered, the water flows into the water outlet channel on the waterway connector 300 through the water outlet channel 211 and the water outlet transfer tube 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 described here.

[0064] Specifically, refer to Fig.13 and Fig.14 The waterway connector 300 further includes a plurality of special-shaped flow guides 320, which are respectively arranged in the plurality of transfer tubes 310, and the plurality of special-shaped flow guides 320 are used to abut against the plurality of seals 413, and the gap between the special-shaped flow guides 320 and the inner wall of the transfer tube 310 is used for water flow. The special-shaped flow guide 320 is a cross flow guide, and part of the structure of the special-shaped flow guide 320 is arranged in the transfer tube 310, and another part of the structure of the special-shaped flow guide 320 extends out of the transfer tube 310. Another part of the structure of the special-shaped flow guide 320 is used to abut against the seal 413, that is, the transfer tube 310 pushes the seal 413 through the special-shaped flow guide 320, and the gap between the special-shaped flow guide 320 and the inner wall of the transfer tube 310 is used for water flow, so that water can flow from the flow channel 211 into the transfer tube 310, or flow from the transfer tube 310 into the flow channel 211.

[0065] In the embodiment of the present invention, 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 buckle block 533 is provided on one side of the first swing arm 530 close to the second swing arm 540, and a second buckle block 541 is provided on one side of the second swing arm 540 close to the first swing arm 530. The mating portion 220 includes a ridge 221 and a groove 222 provided on the filter element 200. The filter element 200 moves in a direction from the mounting port into the accommodating cavity 120 so that the ridge 221 abuts against the first buckle block 533 and the second buckle block 541 respectively to push the second end of the first swing arm 530 and the second end of the second swing arm 540 away from each other, and the first elastic member drives the second end of the first swing arm 530 and the second end of the second swing arm 540 to approach each other so that the first buckle block 533 and the second buckle block 541 are both buckled into the groove 222.

[0070] It should be explained that the first swing arm 530 and the second swing arm 540 are far away from each other, so that the locking assembly is in the second position, and the first swing arm 530 and the second swing arm 540 are close to each other, so that the locking assembly is in the first position. It is understandable that when the filter element 200 needs to be installed, the operator can align the first end of the filter element 200 with the accommodating chamber 120 and insert the filter element 200 into the accommodating chamber 120. In the process of inserting the filter element 200 toward the direction of the water channel joint 300, the convex strip 221 on the outer wall of the adapter 210 can abut against the first buckle block 533 and the second buckle block 541 respectively. As the filter element 200 is continuously inserted, since the first ends of the first swing arm 530 and the second swing arm 540 are both rotatably connected to the frame 100, at this time, under the pushing action of the convex strip 221, the first swing arm 530 and the second swing arm 540 begin to rotate, so that the second ends of the first swing arm 530 and the second swing arm 540 and the first buckle block 533 and the second buckle block 541 begin to move away from each other. As the filter element 200 is continuously inserted, the convex strip 221 slides over the first buckle block 533 and the second buckle block 541 respectively, 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 the first buckle block 533 and the second buckle block 541 are close to each other, so that the first buckle block 533 and the second buckle block 541 are both buckled in the groove 222, and the filter element 200 is locked and fixed in the installation position by the first buckle block 533 and the second buckle block 541. When the filter element 200 is in the installation position, the adapter 210 and the waterway connector 300 are connected with each other.

[0071] refer to Figure 1 and Figure 7 The filter element replacement device also includes a transmission rod 130 arranged on the frame 100, one end of the transmission rod 130 is connected to the operating part 150, and the other end of the transmission rod 130 is provided with a tapered part 131. The force applied to the operating part 150 causes the tapered part 131 to move in the direction from the installation port into the accommodating cavity 120 and drives the second end of the first swing arm 530 and the second end of the second swing arm 540 away from each other, so that the first buckle block 533 and the second buckle block 541 are both separated from the groove 222.

[0072] It is understandable that the conical portion 131 is connected to the control portion 150 through the transmission rod 130. When the control portion 150 is pressed, i.e., a force is applied, the conical portion 131 can squeeze the second ends of the first swing arm 530 and the second swing arm 540. Therefore, under the expansion effect of the conical portion 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 block 533 and the second buckle block 541 move away from each other, and then the first buckle block 533 and the second buckle block 541 are separated from the groove 222. At this time, the second end of the filter element 200 pops out from the accommodating chamber 120, and the removal of the filter element 200 is completed. After the user releases the control portion 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 portion 131 moves in a direction away from the waterway connector 300 and resets, thereby resetting the control portion 150. The first reset assembly 550 includes a tension spring, and two ends of the tension spring are respectively connected to the second end of the first swing arm 530 and the second swing arm 540 .

[0073] As an embodiment of the present invention, the second ends of the first swing arm 530 and the second swing arm 540 are both provided with a limiting groove 532, and the end of the conical portion 131 away from the panel 110 is arranged in the two limiting grooves 532. It can be understood that the conical portion 131 is arranged in the two limiting grooves 532, and the inner walls of the two limiting grooves 532 can limit the conical portion 131, thereby preventing the conical portion 131 from shaking during the process of squeezing the first swing arm 530 and the second swing arm 540, and improving the stability of the process of the second ends of the first swing arm 530 and the second swing arm 540 being stretched. Specifically, the control part 150 also includes an elastic buckle 140, which is arranged on the frame 100, and the transmission rod 130 is buckled on the elastic buckle 140. The elastic buckle 140 can prevent the transmission rod 130 from shaking during the transmission process.

[0074] refer to Figure 7 and Fig. 9The locking mechanism 500 also includes a base 520 and two mounting columns 522. The base 520 is provided with a first avoidance hole 521, and the first avoidance hole 521 is used 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 columns 522 are both arranged on the base 520. The first ends of the first swing arm 530 and the second swing arm 540 are provided with mounting holes 531. The two mounting columns 522 are respectively penetrated into 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 columns 522 respectively. The locking mechanism 500 further includes an upper cover 510 , which is connected to the base 520 . A second avoidance hole 511 is formed on the upper cover 510 . The second avoidance hole 511 is connected to the first avoidance hole 521 . The second avoidance hole 511 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 unit 150, and the control unit 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 block 533 and the second buckle block 541 move away from each other, and at this time, the groove 222 on the adapter 210 is separated from the first buckle block 533 and the second buckle block 541. After the adapter 210 loses the buckling force of the first buckle block 533 and the second buckle block 541, the filter element 200 begins to bounce up under the pushing action of the elastic sealing mechanism 400, thereby completing the disassembly of the filter element 200.

[0076] It should be explained that, under the action of the plurality of second elastic members 411 , the first buckle block 533 and the second buckle block 541 can be respectively pressed and fixed on the convex strip 221 , thereby preventing the filter element 200 from shaking and helping to improve the stability of the connection of the filter element 200 .

[0077] As an embodiment of the present invention, a first guide surface 534 is provided on the side of the first buckle block 533 close to the second buckle block 541, and a second guide surface 223 corresponding to the first guide surface 534 is provided on the convex strip 221. A third guide surface is provided on the side of the second buckle block 541 close to the first buckle block 533, and two second guide surfaces 223 are provided on the convex strip 221, and the two second guide surfaces 223 correspond to the first guide surface 534 and the third guide surface respectively. The two second guide surfaces 223 can respectively abut against the first guide surface 534 and the third guide surface, so that the insertion process of the filter element 200 is smoother, which is conducive to improving the convenience of the user to install the filter element 200, and will not be further described here.

[0078] As an embodiment of the present invention, a limiting hole 121 is provided on the bottom wall of the accommodating 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 be inserted into the second avoidance hole 511 and the first avoidance hole 521 in a correct posture, so that the adapter 210 can be smoothly connected with the waterway connector 300. A gripping portion 230 is also provided at the second end of the filter element 200. After the filter element 200 is inserted into the accommodating cavity 120, the user can grasp the gripping 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, so that the adapter 210 can be smoothly connected with the waterway connector 300.

[0079] The present invention further provides a water purifier, which includes a housing and a filter element replacement device, wherein the filter element replacement device is arranged on the housing. A panel 110 is arranged on the housing. The beneficial effects of the water purifier are not further described here.
