The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] The utility model provides a filter element installation structure, referring to Figure 2 , Figure 6 and Fig.10The filter element installation structure includes a filter element 1, a waterway plate 2, a locking plate 3 and a mounting seat 4. The bottom of the filter element 1 is provided with a connecting portion 11, and the waterway plate 2 is provided with a receiving groove 21 with an opening facing upward and concave downward. In the assembled state, the connecting portion 11 is plugged into the receiving groove 21 from top to bottom. The locking plate 3 is arranged on the waterway plate 2, and the locking plate 3 is annular and surrounds the connecting portion 11 in the assembled state. The waterway plate 2 is swingably mounted on the mounting seat 4, and in the assembled state, the waterway plate 2 reciprocates relative to the mounting seat 4, so that the locking plate 3 moves back and forth laterally relative to the waterway plate 2 to lock or unlock the connecting portion 11.

[0042] Therefore, the filter element installation structure of the present invention is provided with a connection portion 11 at the bottom of the filter element 1 to be plugged with the waterway plate 2, and the waterway plate 2 is swingably installed on the mounting seat 4, and in the assembled state, the waterway plate 2 swings back and forth relative to the mounting seat 4 to make the locking plate 3 move back and forth laterally relative to the waterway plate 2, thereby realizing that the locking plate 3 locks or unlocks the connection portion 11. Since the waterway plate 2 is provided at the bottom of the filter element 1 to allow water to flow between the two, the overall force point of the filter element 1 is located at the bottom, that is, the bottom of the filter element 1 is concentratedly stressed. The present invention installs the locking structure of the filter element 1 at the bottom of the filter element 1, which can improve the stability of the locking structure, so that the filter element 1 is installed in the water purifier with stable and reliable characteristics. In addition, the locking structure of the filter element 1 of the present invention utilizes the swinging of the waterway plate 2 to realize the lateral reciprocating movement of the locking plate 3, which has a simple structure and is easy to install, and is convenient for replacing the filter element 1.

[0043] See also Fig. 9 The waterway plate 2 includes a support plate 22 at the bottom and two side plates 23. The two side plates are arranged at the opposite side edges of the support plate 22 and extend upward, and the two side plates 23 extend along the lateral movement direction of the locking plate 3. A cylindrical rolling member 27 is provided in the middle area at the bottom of the support plate 22. The rolling member 27 is arranged horizontally and its axial direction is perpendicular to the lateral movement direction of the locking plate 3. Therefore, the waterway plate 2 can achieve reciprocating swing by the reciprocating rolling of the rolling member 27 around its own axis. The middle area of ​​the support plate 22 is concave to form a receiving groove 21 with an opening upward. Three waterway interfaces are provided in the receiving groove 21, namely a raw water inlet 24, a pure water outlet 25 and a concentrated water outlet 26. The three waterway interfaces can be designed in a straight line or dispersed in different positions, and are designed according to the factory requirements of the water purifier.

[0044] The filter element 1 includes a filter element body 14, which is vertically arranged. The connecting part 11 is arranged at the bottom of the filter element body 14, and the bottom of the connecting part 11 is provided with three water connection holes adapted to the raw water inlet 24, the pure water outlet 25 and the concentrated water outlet 26, so as to realize the water connection between the filter element 1 and the waterway plate 2.

[0045] The locking plate 3 is arranged on the waterway plate 2, and the waterway plate 2 is located between two oppositely arranged side plates 23, so that the locking plate 3 is limited by the two side plates 23, so that the locking plate 3 can accurately realize lateral reciprocating movement to ensure stable locking and smooth unlocking.

[0046] See also Figure 7 and Fig. 9 At least two stoppers 12 are convexly disposed on the opposite sides of the connection portion 11, and the at least two stoppers 12 are spaced apart along the lateral movement direction of the locking plate 3. The annular inner wall of the locking plate 3 is concave-convexly disposed toward the connection portion 11 so that the concave portion forms an unlocking channel 31 and the convex portion forms a locking portion 32. The number of unlocking channels 31 and the number of locking portions 32 are equal to the number of stoppers 12 and the positions correspond one to one. The unlocking channels 31 are adapted to the corresponding stoppers 12. The locking plate 3 reciprocates laterally relative to the waterway plate 2 so that the locking portion 32 or the unlocking channel 31 moves to the top of the corresponding stopper 12, thereby locking or unlocking the connection portion 11.

[0047] Specifically, in the utility model, the connecting portion 11 is a quasi-rectangular structure, and its two opposite long side surfaces extend along the lateral movement direction of the locking plate 3. Three limit members 12 are respectively provided on the two opposite long side surfaces, and the limit members 12 are convexly arranged relative to the long side surfaces of the connecting portion 11. The receiving groove 21 of the waterway plate 2 is a quasi-rectangular structure so that the connecting portion 11 can be plugged into the receiving groove 21. The annular structure of the locking plate 3 is a quasi-rectangular structure and is adapted to the connecting portion 11. The annular inner wall of the locking plate 3 is concave-convexly arranged to form six unlocking channels 31 and six locking portions 32. In the unlocked state, the six unlocking channels 31 correspond one-to-one to the positions of the six limit members 12, that is, the six unlocking channels 31 are located one-to-one above the six limit members 12, so as to facilitate the six limit members 12 to detach upward through the corresponding unlocking channels 31, so as to separate the filter element 1 from the waterway plate 2, thereby realizing the disassembly of the filter element 1. In the locked state, the six locking portions 32 correspond to the positions of the six limiting members 12 one by one, that is, the six locking portions 32 are located one by one above the six limiting members 12, so that the corresponding limiting members 12 are blocked by the six locking portions 32 to prevent the limiting members 12 from detaching upward, so that the filter element 1 is stably locked on the waterway plate 2, thereby achieving stable installation of the filter element 1.

[0048] The utility model locks or unlocks the connection part 11 by reciprocating the locking plate 3 laterally to move the locking part 32 or the unlocking channel 31 to the top of the corresponding limit member 12, thereby locking or unlocking the filter element 1 by the locking plate 3, which has a simple structure and is easy to operate.

[0049] See also Figure 3 , Figure 4 , Figure 5 and Fig. 9One end of the locking plate 3 in the lateral movement direction has a pushing portion 33 extending outwardly relative to the waterway plate 2, and the mounting seat 4 is provided with a pushing block 41. In the assembled state, the pushing block 41 is located on the outside of the waterway plate 2 and is arranged corresponding to the pushing portion 33. The waterway plate 2 swings back and forth relative to the mounting seat 4 so that the pushing portion 33 moves laterally away from the waterway plate 2 and is located above the pushing block 41, or the pushing portion 33 is pushed by the pushing block 41 to move laterally toward the waterway plate 2, thereby unlocking or locking the locking plate 3. The connecting portion 11.

[0050] Specifically, the push block 41 extends upward from the side of the mounting seat 4 to correspond to the push portion 33. In the unassembled state, the waterway plate 2 swings to a tilted state, with the end of the waterway plate 2 close to the push block 41 as the first end, the end opposite to the first end as the second end, and the first end is higher than the second end. In this state, the locking plate 3 is in a state of synchronous tilt with the waterway plate 2, the end of the locking plate 3 corresponding to the second end of the waterway plate 2 is farther away from the second end, and the push portion 33 of the locking plate 3 is tilted above the push block 41. The filter element 1 is plugged into the waterway plate 2 at the same tilt angle, and the limiter 12 on the connecting portion 11 passes through the corresponding unlocking channel 31 so that the connecting portion 11 is plugged into the receiving groove 21. The filter element 1 is swung and pressed to make it swing and press the first end of the waterway plate 2 downward, so that the waterway plate 2 drives the locking plate 3 to swing to a horizontal state, and the pushing portion 33 of the locking plate 3 is pushed by the pushing block 41 to move laterally toward the waterway plate 2 during the process of sliding downward along the pushing block 41, so that the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves toward the second end to shorten the distance between it and the second end. At this time, the locking portion 32 of the locking plate 3 is located above the corresponding limiting member 12, so that the corresponding limiting member 12 is blocked from disengaging upward by the locking portion 32, so that the filter element 1 is stably locked on the waterway plate 2, thereby achieving stable installation of the filter element 1.

[0051] When unlocking is required, the filter element 1 is swung in the opposite direction so that the filter element 1 presses the second end of the waterway plate 2 downward, so that the waterway plate 2 drives the locking plate 3 to swing to an inclined state, that is, the first end of the waterway plate 2 is higher than the second end. In addition, the locking plate 3 is driven to move laterally so that the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves laterally away from the second end, so that the pushing portion 33 moves away from the waterway plate 2 to above the pushing block 41. At this time, the unlocking channel 31 of the locking plate 3 is located above the corresponding limiter 12 to facilitate the upward disengagement of the limiter 12, so that the filter element 1 can be directly pulled out tilted upward to complete the removal of the filter element 1.

[0052] Therefore, when installing or removing the filter element 1, the utility model only needs to reciprocate the filter element 1 in the assembled state, and the locking portion 32 and the unlocking channel 31 can be switched to fit above the corresponding limiter 12 to automatically lock or unlock the filter element 1. Compared with the filter element installation structure of the prior art, the utility model is not only simple in operation and structure, but also can ensure stable and reliable installation of the filter element 1.

[0053] See also Figure 3 and Figure 5 The push block 41 is provided with a first inclined surface 411 inclined from top to bottom toward the push portion 33, so that the push portion 33 slides downward along the first inclined surface 411 and moves laterally toward the waterway plate 2. When the filter element 1 needs to be locked in the assembled state, the filter element 1 is swung so that the filter element 1 presses the first end of the waterway plate 2 downward, and the waterway plate 2 drives the locking plate 3 to swing to a horizontal state, and in this process, the push portion 33 of the locking plate 3 slides downward along the first inclined surface 411 to move laterally toward the waterway plate 2, so that the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves toward the second end, so that the locking portion 32 of the locking plate 3 is located above the corresponding limit member 12, so that the corresponding limit member 12 is blocked from disengaging upward by the locking portion 32, so that the filter element 1 is stably locked on the waterway plate 2, and the filter element 1 is stably installed.

[0054] In the present invention, when the filter element 1 is unlocked, the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves laterally away from the second end with the aid of external force. Fig. 9 and Fig.10 The locking plate 3 and the waterway plate 2 are elastically connected via an elastic member 5 , and the elastic member 5 is arranged along the lateral movement direction of the locking plate 3 . In the locked state, the elastic member 5 is in a compressed state.

[0055] Specifically, the elastic member 5 is disposed between the end of the locking plate 3 corresponding to the second end of the waterway plate 2 and the second end. When the filter element 1 is locked, the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves toward the second end and compresses the elastic member 5. When unlocked, the locking plate 3 swings along with the waterway plate 2 so that the push block 41 does not exert force on the push portion 33, and the elastic force of the elastic member 5 to restore the deformation pushes the locking plate 3 to move laterally away from the second end of the waterway plate 2.

[0056] In the present invention, the elastic member 5 is a spring.

[0057] See also Figure 3 and Figure 5, the push part 33 is provided with a limit groove 331 extending along the lateral moving direction, and the mounting seat 4 is provided with a vertically arranged limit pin 42, the limit pin 42 is inserted in the limit groove 331, and the limit groove 331 can move laterally relative to the limit pin 42. In the utility model, the limit groove 331 vertically penetrates the push part 33, so that when the limit pin 42 is inserted in the limit groove 331, the push part 33 will not be pushed up, so as to ensure the precise lateral movement of the locking plate 3. Although the swing push part 33 is in a state of tilting from top to bottom, the limit pin 42 has a certain height, so that when the push part 33 is in a tilted state, the top of the limit pin 42 is still in the limit groove 331. Therefore, regardless of the locked or unlocked state, the limit pin 42 can limit the moving direction of the limit groove 331, so that the locking plate 3 always moves back and forth laterally relative to the waterway plate 2, so as to ensure the precise locking and smooth unlocking of the filter element 1.

[0058] See also Figure 8 and Fig. 9 A filter cartridge seat 6 is installed above the locking plate 4. The filter cartridge seat 6 is provided with a guide groove 611 adapted to the connecting portion 11. The groove wall of the guide groove 611 is arranged concave-convex toward the connecting portion 11 so that the concave portion forms a guide channel 612 adapted to the limiting member 12, and two adjacent convex portions of the guide channel 612 form a guide portion 613. The number of guide channels 612 is equal to the number of limiting members 12 and the positions correspond one to one.

[0059] In the present utility model, the guide groove 611 is a rectangular parallelepiped structure adapted to the connection part 11 so that the connection part 11 can pass through the guide groove 611 to be plugged into the receiving groove 21, and the guide channel 612 and the guide part 613 are arranged on two opposite long groove walls. The two opposite long groove walls of the guide groove 611 are both arranged concave-convexly toward the connection part 11 to form three guide channels 612 respectively, and two of each guide channel 612 are formed as guide parts 613 in the length direction of the long groove wall. When the filter element 1 is installed, the corresponding guide channel 612 can be passed through the stopper 12 to allow the connection part 11 to accurately pass through the guide groove 611 and be plugged into the receiving groove 21. The arrangement of the filter element seat 6 improves the installation accuracy of the filter element 1.

[0060] In the unlocked state, the positions of the six guide channels 612, the six unlocking channels 31 and the six limiting members 12 correspond to each other, that is, the adapted guide channels 612, the unlocking channels 31 and the limiting members 12 are arranged correspondingly from top to bottom, so as to facilitate the six limiting members 12 to detach upward through the corresponding unlocking channels 31 and the guide channels 612, so as to separate the filter element 1 from the waterway plate 2, thereby realizing the disassembly of the filter element 1. In the locked state, the positions of the six guide channels 612, the six locking parts 32 and the six limiting members 12 correspond to each other, that is, the adapted guide channels 612, the locking parts 32 and the limiting members 12 are arranged correspondingly from top to bottom, and the locking parts 32 are blocked between the guide channels 612 and the limiting members 12, so as to block the corresponding limiting members 12 from detaching upward to the guide channels 612 through the locking parts 32, so that the filter element 1 is stably locked on the waterway plate 2, thereby realizing the stable installation of the filter element 1.

[0061] Therefore, the working principle of the filter element installation structure of the utility model is as follows:

[0062] In the unassembled state, the waterway plate 2 swings to an inclined state, that is, the first end of the waterway plate 2 is higher than the second end. In this state, the filter element seat 6 and the locking plate 3 are in a synchronously inclined state with the waterway plate 2, the end of the locking plate 3 corresponding to the second end of the waterway plate 2 is farther away from the second end, and the pushing portion 33 of the locking plate 3 is tilted above the pushing block 41. The filter element 1 is sequentially passed through the guide groove 611 and the annular structure of the locking plate 3 and plugged into the waterway plate 2 at the same inclination angle, and the limiter 12 on the connecting portion 11 is sequentially passed through the corresponding guide channel 612 and the unlocking channel 31 to allow the connecting portion 11 to be plugged into the receiving groove 21. See Fig.12 , the filter element 1 is swung and pressed to make the filter element 1 swing and press the first end of the waterway plate 2 downward, so that the waterway plate 2 drives the locking plate 3 and the filter element seat 6 to swing to a horizontal state, and the pushing portion 33 of the locking plate 3 moves laterally toward the waterway plate 2 during the process of sliding obliquely downward along the first inclined surface 411 of the pushing block 41, so that the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves toward the second end to shorten the distance between it and the second end. At this time, the locking portion 32 of the locking plate 3 is located above the corresponding limiting member 12, that is, the locking portion 32 blocks between the guide channel 612 and the limiting member 12, so that the corresponding limiting member 12 is blocked from upwardly disengaging from the guide channel 612 by the locking portion 32, so that the filter element 1 is stably locked in the waterway plate 2, thereby realizing the stable installation of the filter element 1.

[0063] When unlocking is required, refer to Fig.11, the filter element 1 is swung in the opposite direction so that the filter element 1 presses the second end of the waterway plate 2 downward, so that the waterway plate 2 drives the locking plate 3 and the filter element seat 6 to swing to an inclined state, that is, the first end of the waterway plate 2 is higher than the second end. In addition, the elastic member 5 drives the locking plate 3 to move laterally so that the end of the locking plate 3 corresponding to the second end of the waterway plate 2 moves laterally away from the second end, so that the pushing portion 33 moves away from the waterway plate 2 to above the pushing block 41. At this time, the unlocking channel 31 of the locking plate 3 is located above the corresponding limiting member 12 to facilitate the limiting member 12 to disengage upward through the guide channel 612, so that the filter element 1 can be directly pulled out tilted upward to complete the removal of the filter element 1.

[0064] See also Figure 7 , Fig. 9 , Fig.11 and Fig.12 The limit member 12 is provided with a second inclined surface 121 inclined from top to bottom on the inner wall of the corresponding guide channel 612 facing away from it, the inner wall of the guide channel 612 is provided with a third inclined surface 6121 adapted to the second inclined surface 121, and the inner wall of the unlocking channel 31 is provided with a fourth inclined surface 311 adapted to the second inclined surface 121.

[0065] Specifically, the upper part of the stopper 12 is a cubic structure, and the lower part of the stopper 12 is a cone structure, that is, the first side surface of the lower part of the stopper 12 away from the connecting part 11 and the two opposite second side surfaces arranged adjacent to the first side surface are both inclined structures. The first side surface is inclined from top to bottom toward the connecting part 11, and the two second side surfaces are inclined from top to bottom toward each other. Correspondingly, the upper part of the inner wall corresponding to the channel opening of the guide channel 612 is adapted to the inclined setting of the first side surface, and the upper parts of the two opposite side inner walls of the guide channel 612 are adapted to the corresponding second side surfaces to form a third inclined surface 6121 in the guide channel 612. Similarly, the upper part of the inner wall corresponding to the channel opening of the unlocking channel 31 is adapted to the inclined setting of the first side surface, and the upper parts of the two opposite side inner walls of the unlocking channel 31 are adapted to the corresponding second side surfaces to form a fourth inclined surface 311 in the unlocking channel 31. Therefore, the utility model facilitates the stopper 12 to pass through the guide channel 612 and the unlocking channel 31 smoothly by setting the inclined surface structure, so as to facilitate the installation and disassembly of the filter element 1.

[0066] In addition, the side surface of the locking portion 32 facing the corresponding limiting member 12 is an inclined surface 321 , which has an avoidance function to ensure that the limiting member 12 passes through the unlocking channel 31 smoothly.

Therefore, in the assembled state, the filter element seat 6 is wrapped around the lower part of the filter element 1, so that the filter element 1 and the waterway plate 3 are stably installed through the filter element seat 6.

[0068] Furthermore, the clamping block 13 is disposed at the lower part of the filter element body 14 , and the clamping structure between the clamping block 13 and the clamping groove 621 can prevent the filter element 1 and the filter element seat 6 from rotating relative to each other, further improving the stability and reliability of the installation of the filter element 1 .

[0069] In addition to the above filter element installation structure, the utility model also provides a water purifier, see Figure 1 and Figure 2 The water purifier includes a housing 7 and a filter element mounting structure, wherein a mounting cavity 71 is provided in the housing 7, and the filter element mounting structure is mounted in the mounting cavity 71. The filter element mounting structure is mounted in the water purifier, so that the filter element 1 can be stably and reliably mounted, and the filter element 1 can be easily removed from the water purifier.

[0070] Specifically, the housing 1 includes a housing body 72 and a blocking portion 73. The housing body 72 is provided with an opening, and the blocking portion 73 is installed at the opening, so that the blocking portion 73 and the housing body 72 form a closed structure, and a mounting cavity 71 is formed between the blocking portion 73 and the housing body 72. The mounting seat 4 is mounted on the housing body 72, and the waterway plate 2, the locking plate 3 and the filter element seat 6 are assembled from bottom to top into an integral structure and mounted on the mounting seat 4. The waterway plate 2 can swing relative to the mounting seat 4 to drive the locking plate 3 and the filter element seat 6 to swing synchronously.

[0071] The installation cavity 71 is adapted to the filter element 1, and the housing body 72 and the blocking portion 73 are detachable. When the filter element 1 needs to be installed, the blocking portion 73 is removed, and the connecting portion 11 of the filter element 1 is passed through the filter element seat 6 and the locking plate 3 in sequence to be plugged into the waterway plate 2. After the filter element 1 is locked, the blocking portion 73 is installed to complete the assembly of the water purifier 1.

[0072] When the filter element 1 needs to be replaced, the sealing portion 73 is removed, the filter element 1 is unlocked to pull out the filter element 1, and then a new filter element 1 is installed, and the sealing portion 73 is installed on the housing body 72, thereby completing the replacement of the filter element 1.

[0073] The water purifier of the utility model can complete the replacement of the filter element 1 through a simple structure and operation, and is suitable for wide application.
