Description

Technical Field

[0001] This utility model relates to the technical field of water purification devices, and in particular to an installation structure for a filter element assembly and a water purification device. Background Technology

[0002] Filter cartridges are crucial components in the water purification process. During use, they continuously intercept various impurities in the water to achieve filtration and purification. Long-term use leads to a decline in the filtration performance of the filter cartridges, necessitating regular replacement. Replacement requires removing the old filter cartridge from the water purifier and then installing the new or cleaned cartridge. In existing technology, filter cartridges are installed using a locking mechanism. However, this mechanism makes it difficult for users to accurately determine if the filter cartridge is properly installed, potentially leading to leaks at the joints.

[0003] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0004] This utility model addresses the problem mentioned above where users cannot effectively determine whether the filter element assembly is properly installed when installing it using a locking mechanism, which can easily lead to water leakage at the joint of the filter element assembly in the water purification equipment. It proposes an installation structure for the filter element assembly and a water purification equipment.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] An installation structure for a filter element assembly is provided at the end of the filter element assembly for detachably installing the filter element assembly in a water purification device. The installation structure includes a mounting base, a top cover that fits onto the mounting base, and a locking mechanism disposed between the mounting base and the top cover. The locking mechanism is connected to a positioning member that extends into the top cover. The positioning member is driven to telescopically move relative to the top cover by the locking mechanism, and the locking mechanism has an unlocked state and a locked state corresponding to the positioning member extending out of and retracting into the top cover, respectively.

[0007] As described above, in the installation structure of a filter element assembly, the locking mechanism includes a first locking block and a second locking block slidably disposed within the mounting base, and a driving component disposed between the first locking block and the second locking block. The mounting base is provided with a first slide rail corresponding to the first locking block and a second slide rail corresponding to the second locking block. The driving component drives the first locking block to extend and retract relative to the mounting base along the first slide rail, and the second locking block to extend and retract relative to the mounting base along the second slide rail, thereby switching between the locked state and the unlocked state.

[0008] In the filter element assembly mounting structure described above, the positioning member is connected to the driving assembly, and the driving assembly drives the positioning member to move telescopically relative to the top cover along the through hole.

[0009] As described above, in the installation structure of a filter element assembly, the drive assembly includes an operating component and a linkage component connected to the operating component. The positioning component is connected to the linkage component, and the linkage component is disposed between the first locking block and the second locking block. The operating component is rotatably connected to the mounting base. The linkage component is driven to generate linkage by rotating relative to the mounting base, and the first locking block and the second locking block are driven to extend and retract relative to the mounting base by the linkage component.

[0010] As described above, in the installation structure of a filter element assembly, one end of the operating member is provided with a driving part, and one side of the linkage component is provided with a transmission rod. The transmission rod extends to be opposite to the driving part. By rotating the operating member relative to the mounting base, the driving part is driven to rotate closer to the transmission rod, thereby driving the transmission rod to move upward within the mounting base, causing the linkage component to be linked, thus enabling the locking mechanism to switch from the locked state to the unlocked state.

[0011] As described above, in the installation structure of a filter element assembly, the operating component includes a handle and a rotating shaft connected to the handle. The operating component is rotatably connected to the mounting base via the rotating shaft. One end of the rotating shaft is provided with the driving part. The handle rotates relative to the mounting base via the rotating shaft to drive the driving part to rotate closer to the transmission rod, and the driving part drives the transmission rod to move upward within the mounting base. The handle has a closed position and a disassembled position corresponding to the locked state and the unlocked state, respectively.

[0012] As described above, the installation structure of a filter element assembly includes a linkage component comprising a first linkage member and a second linkage member. The first linkage member is hinged to the first locking block and the mounting base, and the second linkage member is hinged to the second locking block and the mounting base. One end of the positioning member is provided with a connecting rod, which is slidably disposed within the mounting base. The first linkage member and the second linkage member are respectively hinged to the connecting rod. The linkage component generates a linkage to drive the connecting rod to move within the mounting base, thereby causing the positioning member to extend and retract relative to the top cover. The transmission rod is disposed on one side of the first linkage member or the second linkage member.

[0013] As described above, in the installation structure of a filter element assembly, both the first linkage member and the second linkage member include a first arm and a second arm connected to each other, with an included angle between the first arm and the second arm; a first hinge portion is provided at the end of the first arm away from the second arm, the first hinge portion being used to hinge with the first locking block or the second locking block; a second hinge portion is provided at the connection between the first arm and the second arm, the second hinge portion being used to hinge with the mounting base; and a third hinge portion is provided at the end of the second arm away from the first arm, the third hinge portion being used to hinge with the connecting rod.

[0014] As described above, in the installation structure of a filter element assembly, the locking mechanism further includes a first reset member and a second reset member. The first reset member is disposed between the first locking block and the mounting base, and is used to push the first locking block to extend outward toward the mounting base. The second reset member is disposed between the second locking block and the mounting base, and is used to push the second locking block to extend outward toward the mounting base.

[0015] On the other hand, this utility model also provides a water purification device, including a filter element assembly and an installation structure for the filter element assembly as described above.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By connecting the positioning component with the locking mechanism, the locking mechanism drives the positioning component to extend and retract relative to the top cover, making the installation status of the filter element assembly in the water purification equipment visible, which makes it easier for users to accurately install the filter element assembly, improves the connection stability of the filter element assembly, and prevents water leakage caused by unstable joints of the filter element assembly in the water purification equipment.

[0018] 2. The positioning component is directly driven by the locking mechanism, eliminating the need for a separate driving device. This simplifies the design of the filter element assembly installation structure and reduces the size of the installation structure.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0030] Example 1:

[0031] like Figure 1As shown in Figure 5, this utility model provides a water purification device, which includes a filter element assembly 6. One end of the filter element assembly 6 has an installation structure, allowing the filter element assembly 6 to be detachably installed in the water purification device. Specifically, the installation structure includes a mounting base 1, a top cover 2 that fits onto the mounting base 1, and a locking mechanism 3 located between the mounting base 1 and the top cover 2. The mounting base 1 is used to connect to the filter element assembly 6. The locking mechanism 3 is connected to a positioning member 4, which extends into the top cover 2. The locking mechanism 3 drives the positioning member 4 to extend and retract relative to the top cover 2, and the locking mechanism 3 has an unlocked state and a locked state corresponding to the positioning member 4 extending out of and retracting into the top cover 2, respectively. By providing the positioning member 4 in the installation structure of the filter element assembly 6, the user can easily install the filter element assembly 6. When installing the filter element assembly 6, it is possible to directly observe whether the positioning member 4 protrudes from the top cover end face, thereby determining whether the filter element assembly 6 is installed correctly, allowing the user to accurately install the filter element assembly 6. The top cover end face can be the top surface or side surface of the top cover 2. By connecting the positioning member 4 to the locking mechanism 3, the locking mechanism 3 drives the positioning member 4 to extend and retract relative to the top cover 2, making the installation status of the filter element assembly 6 in the water purification equipment visible. This facilitates accurate installation by the user, improves the connection stability of the filter element assembly 6, and prevents leaks caused by instability at the joints of the filter element assembly 6 in the water purification equipment. Simultaneously, the positioning member 4 is directly driven by the locking mechanism 3, eliminating the need for a separate driving device, which simplifies the specific design of the installation structure and reduces its volume.

[0032] In practical applications, such as Figure 1 and Figure 4 As shown, when the positioning member 4 retracts into the top cover 2, this includes at least two situations: the end face of the positioning member 4 is lower than the end face of the top cover, and the end face of the positioning member 4 is flush with the end face of the top cover. This indicates that the filter element assembly 6 is installed in the water purification equipment. At this time, the locking mechanism 3 is in a locked state, and the filter element assembly 6 can be fixed in the water purification equipment through the locking mechanism 3, and the filter element assembly 6 can operate normally. Figure 3 and Figure 5 As shown, when the positioning member 4 extends outward relative to the top cover 2 through the locking mechanism 3, that is, the end face of the positioning member 4 protrudes from the end face of the top cover, it indicates that the filter element assembly 6 is not installed properly in the water purification equipment. The joint of the filter element assembly 6 in the water purification equipment is prone to leakage, and the installation position of the filter element assembly 6 in the water purification equipment needs to be adjusted. Among them, when the filter element assembly 6 is in the unlocked state, the extension length of the end face of the positioning member 4 relative to the end face of the top cover is the largest.

[0033] In some alternative embodiments, the positioning member 4 has a first position and a second position relative to the top cover 2, respectively corresponding to the unlocked state and the locked state. The locking mechanism 3 drives the positioning member 4 to extend and retract relative to the top cover 2, thereby switching the positioning member 4 between the first position and the second position. Figure 5 As shown, when the positioning member 4 is in the first position, the locking mechanism 3 is in the unlocked state, the filter element assembly 6 can be removed from the water purification equipment, and the end face of the positioning member 4 is recessed relative to the end face of the top cover or flush with the end face of the top cover, that is, the end face of the positioning member 4 does not protrude from the end face of the top cover; Figure 4 As shown, when the positioning member 4 is in the second position, the locking mechanism 3 is in the locked state. At this time, the filter element assembly 6 is fixedly installed in the water purification equipment, and the filter element assembly 6 is installed in place. The end face of the positioning member 4 protrudes from the end face of the top cover.

[0034] In other alternative embodiments, such as Figure 4 and Figure 5 As shown, the top cover end face is the top surface of the top cover 2. The top cover 2 has a through hole for the positioning member 4 to pass through. After assembly, at least part of the positioning member 4 is placed in the through hole. Optionally, the positioning member 4 is a rod-shaped structure adapted to the through hole, which is simple in structure and easy to implement. In practical applications, the positioning member 4 can be driven to move up and down along the through hole relative to the top surface by the locking mechanism 3 to visualize the installation status of the filter element assembly 6. When the locking mechanism 3 is in the locked state, at least part of the positioning member 4 is placed in the through hole, and the end face of the positioning member 4 does not exceed the top cover end face. When the positioning member 4 moves up and down along the through hole relative to the top surface by the locking mechanism 3, the positioning member 4 can extend to the outside of the top cover 2. When the end face of the positioning member 4 extends the longest relative to the top cover end face, it indicates that the filter element assembly 6 is installed in place. Further optionally, the through hole is located in the middle of the top cover 2, and the positioning member 4 is set corresponding to the through hole.

[0035] In some alternative embodiments, an identifier may be provided on the outer periphery of the positioning member 4. The identifier may be implemented by means of color, pattern, line, etc. Optionally, when the identifier is flush with the top end cap or when the identifier is exposed on the top end cap, the identifier can be seen by a person, indicating that the filter element assembly 6 is installed in place.

[0036] In other alternative embodiments, such as Figure 1As shown, the mounting structure is located at the end of the filter element assembly 6 away from the fluid interface 62. Specifically, the filter element assembly 6 includes a filter bottle 61 and a filter element body disposed within the filter bottle 61. One end of the filter bottle 61 is provided with a fluid interface 62, which is connected to the water system in the water purification equipment. The fluid interface 62 is used to input and output water to the filter element body. The mounting structure is located at the end of the filter bottle 61 away from the fluid interface 62 to facilitate the quick disassembly and replacement of the filter element body without having to remove the entire filter element assembly 6 from the water purification equipment.

[0037] In some alternative embodiments, the locking mechanism 3 may employ a common filter element locking structure, which can drive the positioning member 4 to extend and retract relative to the top cover 2.

[0038] Example 2:

[0039] Based on Embodiment 1, Embodiment 2 is another optional implementation of the locking mechanism 3, such as... Figure 1 As shown in Figure 7, the mounting base 1 has a receiving cavity to accommodate the locking mechanism 3. The locking mechanism 3 includes a first locking block 31 and a second locking block 32 slidably disposed within the mounting base 1, and a driving assembly 33 disposed between the first locking block 31 and the second locking block 32. The mounting base 1 has a first slide rail 11 corresponding to the first locking block 31 and a second slide rail 12 corresponding to the second locking block 32. The top cover 2 has a first opening corresponding to the first slide rail 11 and a second opening corresponding to the second slide rail 12. The driving assembly 33 drives the first locking block 31 to extend and retract relative to the mounting base 1 along the first slide rail 11, and the second locking block 32 to extend and retract relative to the mounting base 1 along the second slide rail 12, thereby switching the locking state and the locked position. The first locking block 31 and the second locking block 32 can be moved in opposite directions within the mounting base 1 by the drive component 33, so that the first locking block 31 and the second locking block 32 extend outward from the mounting base 1 via the first slide rail 11 and the second slide rail 12 respectively. At this time, the locking mechanism 3 can be switched to the locked state, and the filter element assembly 6 is fixedly installed in the water purification equipment. The first locking block 31 and the second locking block 32 can be moved towards each other within the mounting base 1 by the drive component 33, so that the first locking block 31 and the second locking block 32 retract into the mounting base 1 via the first slide rail 11 and the second slide rail 12 respectively. At this time, the locking mechanism 3 can be switched to the unlocked state, and the filter element assembly 6 can be removed from the water purification equipment.

[0040] Furthermore, the locking mechanism 3 also includes a reset member disposed within the mounting base 1. The reset member is used to push the first locking block 31 and the second locking block 32 outwards from the mounting base 1, so that the locking mechanism is switched to the locked state. Specifically, the reset member includes a first reset element 34 and a second reset element 35. The first reset element 34 is disposed between the first locking block 31 and the mounting base 1, and is used to push the first locking block 31 outwards from the mounting base 1. The second reset element 35 is disposed between the second locking block 32 and the mounting base 1. Between 1 and 2, the first locking block 31 and the second locking block 32 are used to push the second locking block 32 outward toward the outside of the mounting base 1. In practical applications, when the user releases the force applied to the operating member 331, the first locking block 31 and the second locking block 32 can extend outward toward the outside of the mounting base 1 through the first reset member 34 and the second reset member 35, so that the locking mechanism 3 is switched to the locked state. At this time, the positioning member 4 retracts into the top cover 2 to indicate that the filter element assembly 6 is installed in place. At the same time, when the first locking block 31 and the second locking block 32 extend outward, they can drive the driving component 33 to reset. In some alternative embodiments, the mounting base 1 is provided with a first mounting post 14 for installing the first reset member 34 and a second mounting post 15 for installing the second reset member 35. The first locking block 31 and the second locking block 32 are both provided with mounting grooves 311 for installing the first reset member 34 / second reset member 35. The structure is simple and easy to disassemble and assemble, so as to enhance the connection stability of the first reset member 34 and the second reset member 35, thereby enhancing the movement stability of the first locking block 31 and the second locking block 32.

[0041] On the other hand, the water purification equipment can be equipped with a first lock hole and a second lock hole corresponding to the first lock block 31 and the second lock block 32, respectively. When the locking mechanism 3 is in the locked state, the first lock block 31 is inserted into the first lock hole and the second lock block 32 is inserted into the second lock hole. When the locking mechanism 3 is in the unlocked state, the first lock block 31 is disengaged from the first lock hole and the second lock block 32 is disengaged from the second lock hole.

[0042] In some alternative embodiments, the first locking block 31 and the second locking block 32 are arranged radially symmetrically within the mounting base 1, and correspondingly, the first slide rail 11 and the second slide rail 12 are arranged radially symmetrically within the mounting base 1.

[0043] In some alternative embodiments, the moving direction of the positioning element 4 is perpendicular to the moving direction of the first locking block 31 and the second locking block 32.

[0044] Furthermore, the positioning member 4 is connected to the driving component 33, and the driving component 33 drives the positioning member 4 to move telescopically relative to the top cover 2; wherein, the maximum extension length of the end face of the positioning member 4 relative to the end face of the top cover is consistent with the maximum retraction distance of the first locking block 31 and the second locking block 32 toward the interior of the mounting base 1.

[0045] The optional implementations of the driving component 33 are as follows, such as... Figure 2 , 6 As shown in Figure 7, the drive assembly 33 includes an operating element 331 and a linkage assembly 333 connected to the operating element 331. The positioning element 4 is connected to the linkage assembly 333. The linkage assembly 333 is disposed between the first locking block 31 and the second locking block 32. The operating element 331 is rotatably connected to the mounting base 1, and at least part of the operating element 331 is exposed outside the top cover 2 to facilitate user operation. In practical applications, the user can manually rotate the operating element 331, and the operation element 331 rotates relative to the mounting base 1 to drive the linkage assembly 333 to generate linkage, and the linkage assembly 333 drives the first locking block 31 and the second locking block 32 to move telescopically relative to the mounting base 1.

[0046] Furthermore, such as Figure 2 , 6As shown in Figure 7, one end of the operating member 331 is provided with a driving part 3313, and one side of the linkage component 333 is provided with a transmission rod 332. The transmission rod 332 extends to be opposite to the driving part 3313, that is, the transmission rod 332 extends to the rotation path of the driving part 3313. By rotating the operating member 331 relative to the mounting base 1, the driving part 3313 is driven to rotate closer to the transmission rod 332, thereby driving the transmission rod 332 to move upward within the mounting base 1, causing the linkage component 333 to be linked, thus changing the locking mechanism from the locked state to the unlocked state; furthermore, the transmission rod 332 extends to the unlocking rotation path of the driving part 3313, when the filter is disassembled... When the filter element assembly 6 is installed, the operating member 331 rotates counterclockwise relative to the mounting base 1, causing the driving part 3313 to rotate closer to the transmission rod 332, thereby driving the transmission rod 332 to move upward within the mounting base 1. Simultaneously, the linkage component 333 drives the first locking block 31 and the second locking block 32 to retract inward toward the mounting base 1, achieving the unlocked state. At the same time, the linkage component 333 drives the positioning member 4 to extend outward toward the top cover 2, allowing the user to directly observe the installation status of the filter element assembly 6 and indicating to the user that the locking mechanism 3 is in the unlocked state. When installing the filter element assembly 6, the force applied to the operating member 331 can be released, and the user can directly press the positioning member 4 to lock the filter element assembly 6. Positioning member 4 retracts inward relative to the top cover 2, and drives the linkage component 333 to generate linkage, so that the first locking block 31 and the second locking block 32 extend outward toward the mounting base 1 to achieve the locking state of the locking mechanism 3. When the positioning member 4 retracts into the top cover 2, it indicates that the filter element assembly 6 is installed in place. At the same time, the linkage component 333 can also drive the transmission rod 332 to move down and reset relative to the mounting base 1, and drive the driving part 3313 to rotate in the opposite direction and reset, thereby realizing the reset of the operating member 331; or, when the user releases the force applied to the operating member 331, the first locking block 31 and the second locking block 32 can be directly driven by the first locking member 331 to move down and reset relative to the mounting base 1. A reset member 34 and a second reset member 35 extend outward from the mounting portion to switch the locking mechanism 3 to the locked state. In this scheme, the first locking block 31 and the second locking block 32 are automatically ejected to the outside of the mounting base 1 directly through the reset member, without needing to press the positioning member 4 separately to move it down and reset. Moreover, the first locking block 31 and the second locking block 32 can drive the linkage component 333 to generate linkage. The linkage component 333 can drive the transmission rod 332 to move down and reset relative to the mounting base 1, and drive the driving part 3313 to rotate in the opposite direction and reset through the transmission rod 332, thereby realizing the automatic reset of the operating member 331, which is convenient for users to disassemble and assemble the filter element assembly 6 and is easy to operate.

[0047] The optional implementations of the operating element 331 are as follows, such as... Figure 2 , 6 As shown in Figure 7, the operating component 331 includes a handle 3311 and a rotating shaft 3312 connected to the handle 3311. The rotating shaft 3312 is provided at both ends of the handle 3311. The mounting base 1 has a connection structure corresponding to the rotating shaft 3312. The operating component 331 is rotatably connected to the mounting base 1 via the rotating shaft 3312. The rotating shaft 3312 can pass through the top cover 2, and the handle 3311 is positioned outside the top cover 2. The other end of the rotating shaft 3312 is provided with the driving part 3313. 3311 rotates relative to the mounting base 1 via the pivot 3312, thereby driving the drive unit 3313 to rotate closer to the transmission rod 332, and driving the transmission rod 332 to move upward within the mounting base 1 via the drive unit 3313; the handle 3311 has a closed position and a disassembled position corresponding to the locked state and the unlocked state, respectively; in practical applications, the handle 3311 can rotate relative to the mounting base 1 and the top cover 2 around the pivot 3312 under external force, thereby switching the closed position and the disassembled position of the handle 3311. In the disassembly position, when the filter element assembly 6 is disassembled, the handle 3311 rotates counterclockwise to the disassembly position under external force. At this time, the handle 3311 is perpendicular to the top cover 2, and the handle 3311 drives the drive unit 3313 to rotate synchronously through the rotating shaft 3312. The drive unit 3313 drives the transmission rod 332 to move upward in the mounting base 1, and the linkage assembly 333 drives the first locking block 31 and the second locking block 32 to retract inward toward the mounting base 1. At the same time, the positioning member 4 extends out of the top cover 2. The top cover 2 is external to achieve the unlocked state of the locking mechanism 3; when the locking mechanism 3 is switched to the locked state, the handle 3311 can be rotated clockwise relative to the top cover 2 to the closed position by external force through the rotating shaft 3312, at which time the handle 3311 is parallel to the top cover 2; optionally, the top cover 2 is provided with a receiving groove 21 for accommodating the handle 3311 and a groove 22 located on one side of the receiving groove 21, the groove 22 can be inserted by human fingers, so that the user can better grasp the handle 3311.

[0048] Furthermore, such as Figure 2 , 6As shown in Figure 7, the drive unit 3313 includes a connecting part 33131 connected to the rotating shaft 3312 and an extension part 33132 connected to the connecting part 33131. A preset angle is provided between the extension part 33132 and the connecting part 33131, preferably 90 degrees. The extension part 33132 extends toward the connecting part 33131. The extension part 33132 rotates toward or away from the transmission rod 332 through the rotating shaft 3312, so that the locking mechanism 3 switches between the locked state and the unlocked state.

[0049] The optional implementations of the linkage component 333 are as follows: Figure 2 , 4 As shown in 5, 6, and 7, Figure 4 and Figure 6 This indicates that the locking mechanism 3 is in the locked state. Figure 5 and Figure 7This indicates that the locking mechanism 3 is in the unlocked state. The linkage component 333 includes a first linkage member 3331 and a second linkage member 3332. The first linkage member 3331 is hinged to the first locking block 31 and the mounting base 1, and the second linkage member 3332 is hinged to the second locking block 32 and the mounting base 1. One end of the positioning member 4 is provided with a connecting rod 5, which is slidably disposed in the mounting base 1. The first linkage member 3331 and the second linkage member 3332 are respectively hinged to the connecting rod 5. The linkage component 333 generates a linkage to drive the connecting rod 5 to move within the mounting base 1, thereby causing the positioning member 4 to move telescopically relative to the top cover 2. The transmission... Rod 332 is located on one side of the first linkage 3331 or the second linkage 3332; specifically, both the first linkage 3331 and the second linkage 3332 include a first support arm 3331a and a second support arm 3331b connected to each other. The structures of the first linkage 3331 and the second linkage 3332 are similar. Taking the first linkage 3331 as an example, there is an included angle between the first support arm 3331a and the second support arm 3331b. One end of the first support arm 3331a is provided with a first hinge portion 33301 for hinged with the first locking block 31, and a second hinge portion 33302 for hinged with the mounting base 1 is provided between the first support arm 3331a and the second support arm 3331b. The other end of the second arm 3331b is provided with a third hinge portion 33303 for hinged with the connecting rod 5. The three hinge portions can be respectively configured as hinge shafts or hinge holes. The third hinge portion 33303 of the first linkage member 3331 and the third hinge portion 33303 of the second linkage member 3332 are respectively hinged with the connecting rod 5. The connecting rod 5 is perpendicular to the positioning member 4, and the mounting base 1 is provided with a third slide rail 13 adapted to the connecting rod 5. The connecting rod 5 is slidably disposed within the third slide rail 13. In practical applications, when the filter element assembly 6 is disassembled, the handle 3311 is rotated to the disassembly position by external force, and the transmission rod 332 is driven by the drive part 3. The force of 313 moves upward within the mounting base 1, and the transmission rod 332 applies an upward force to the first linkage member 3331 or the second linkage member 3332, causing the first linkage member 3331 and the second linkage member 3332 to drive the connecting rod 5 upward along the third slide rail 13 through their respective third hinge points, and drive the positioning member 4 to extend out of the top cover 2 through the connecting rod 5. At the same time, the first linkage member 3331 and the second linkage member 3332 drive the first locking block 31 and the second locking block 32 to retract inward toward the mounting base 1 along the first slide rail 11 and the second slide rail 12 respectively through their respective second hinge points and first hinge points, so as to realize the unlocked state of the locking mechanism 3.When the filter element assembly 6 is installed, the user can release the force applied to the handle 3311. The first locking block 31 and the second locking block 32 can extend outward from the mounting base 1 via the first reset member 34 and the second reset member 35 respectively along the first slide rail 11 and the second slide rail 12. Through the three corresponding hinge points of the first linkage member 3331 and the second linkage member 3332, the transmission rod 332 and the connecting rod 5 are driven to move downward and reset within the mounting base 1, thereby resetting the locking mechanism 3 and converting it into the locking mechanism. The system is designed so that the user can directly observe whether the positioning component 4 retracts into the top cover 2 to determine whether the filter element assembly 6 is installed correctly. Secondly, by setting the linkage component 333, the volume of the locking mechanism 3 can be reduced, improving the space utilization of the mounting base 1 and thus reducing the volume of the installation structure. Furthermore, after the filter element assembly 6 is installed, the user can directly rotate the handle 3311 to the retracted position. When disassembling the filter element assembly 6, the user only needs to rotate the handle 3311 again to the disassembly position. Preferably, the first linkage component 3331 and the second linkage component 3332 are L-shaped components; the third slide rail 13 is perpendicular to the first slide rail 11 and the second slide rail 12.

[0050] On the other hand, based on the installation structure of the filter element assembly 6 in the above embodiments, the present invention also provides an installation method for the filter element assembly 6, which includes at least the following steps:

[0051] Provides filter element assembly 6 and the mounting structure of filter element assembly 6 as described above;

[0052] The filter element assembly 6 is fixedly installed on the lower part of the mounting base 1, and the locking mechanism 3 is switched to the unlocked state; wherein, the mounting structure is installed on the end of the filter element assembly 6 away from its fluid interface 62;

[0053] Furthermore, after the mounting structure is installed in the filter element assembly 6, the handle 3311 is rotated to the disassembly position, causing the first locking block 31 and the second locking block 32 to retract toward the mounting base 1. At the same time, the positioning member 4 protrudes from the top cover 2, indicating that the locking mechanism 3 is in the unlocked state.

[0054] Place the filter element assembly 6 in the water purification device and switch the locking mechanism 3 to the locked state;

[0055] Furthermore, the locking mechanism 3 is kept in the unlocked state, the filter element assembly 6 is placed in the installation position in the water purification equipment, and the filter element assembly 6 is moved up and down so that the first locking block 31 and the second locking block 32 are aligned with the corresponding first locking hole and second locking hole in the installation position. The handle 3311 is released, and the first locking block 31 and the second locking block 32 are automatically ejected from the outside of the mounting base 1 and inserted into the first locking hole and the second locking hole by the push of the first reset member 34 and the second reset member 35.

[0056] Alternatively, the locking mechanism 3 is kept in the unlocked state, and the filter element assembly 6 is placed in the installation position in the water purification equipment. The handle 3311 is released. At this time, the first locking block 31 is simultaneously subjected to the force of the first reset member 34 and the inner wall of the installation position, and the second locking block 32 is simultaneously subjected to the force of the second reset member 35 and the inner wall of the installation position. The filter element assembly 6 is moved up and down so that the first locking block 31 and the second locking block 32 are aligned with the corresponding first and second locking holes in the installation position. When the first locking block 31 and the second locking block 32 are aligned with the first and second locking holes, the first locking block 31 and the second locking block 32 automatically pop out of the outside of the mounting base 1 and insert into the first and second locking holes.

[0057] Determine whether the positioning element 4 protrudes from the top cover 2;

[0058] If not, the locking mechanism 3 is in the locked state, indicating that the filter element assembly 6 is installed in place and the installation of the filter element assembly 6 is completed;

[0059] If so, adjust the position of the locking mechanism 3 within the water purification device, that is, repeat the steps of "moving the filter element assembly 6 up and down so that the first locking block 31 and the second locking block 32 are aligned with the corresponding first and second locking holes in the mounting position, and the first locking block 31 and the second locking block 32 automatically pop out of the mounting base 1 and insert into the first and second locking holes" until the positioning member 4 protrudes from the top cover 2, so that the locking mechanism 3 is in the locked state.

[0060] This allows for the installation and fixation of the filter element assembly 6 in the water purification equipment. The operation is simple. During the actual installation process, the user only needs to turn the handle 3311, place the filter element assembly 6 with the installation structure installed in the installation position in the water purification equipment, and move the filter element assembly 6 up and down within the installation position to complete the installation of the filter element assembly 6. When disassembling the filter element assembly 6, the user only needs to turn the handle 3311 and pull out the filter element assembly 6. This makes it convenient for users to disassemble, install, and replace the filter element assembly 6 themselves.

[0061] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
