[0002] The filter element assembly is an important component in the water purification process. When in use, the filter element assembly will continuously intercept various impurities in the water to achieve filtration and purification of the water. Long-term use will cause the filtration performance of the filter element assembly to decline, so the filter element assembly needs to be replaced regularly. When replacing, the user needs to remove the old filter element assembly from the water purification equipment, and then install the new filter element assembly or the cleaned filter element assembly in the water purification equipment. In the prior art, the filter element assembly is installed in the water purification equipment through a locking mechanism, but when the user installs the filter element assembly through the locking mechanism, it is impossible to effectively distinguish whether the filter element assembly is installed in place, which easily causes water leakage at the joint of the filter element assembly in the water purification equipment.

[0021] Embodiment 1: like Figure 1As shown in FIG5 , the present invention provides a water purification device, which includes a filter element assembly 6, and a mounting structure is provided at one end of the filter element assembly 6, through which the filter element assembly 6 can be detachably installed in the water purification device; specifically, the mounting structure includes a mounting seat 1, a top cover 2 covering the mounting seat 1, and a locking mechanism 3 provided between the mounting seat 1 and the top cover 2, the mounting seat 1 is used to connect with the filter element assembly 6, the locking mechanism 3 is connected with a positioning member 4, the positioning member 4 extends into the top cover 2, the positioning member 4 is driven to telescopically move relative to the top cover 2 by the locking mechanism 3, and the locking mechanism 3 has an unlocking state and a locking state corresponding to the positioning member 4 extending out and retracting into the top cover 2 respectively; by arranging the positioning member 4 in the mounting structure of the filter element assembly 6, the user can install the filter element 6 when installing the filter element 6. When installing the filter element assembly 6, it is possible to directly observe whether the positioning member 4 protrudes from the end face of the top cover, thereby judging whether the filter element assembly 6 is installed in place, so that the user can accurately install the filter element assembly 6; wherein, the end face of the top cover can be the top face or the side face of the top cover 2; by connecting the positioning member 4 with the locking mechanism 3, the locking mechanism 3 drives the positioning member 4 to perform telescopic movement relative to the top cover 2, so that the installation status of the filter element assembly 6 in the water purification equipment can be visualized, which is convenient for the user to accurately install the filter element assembly 6, improve the connection stability of the filter element assembly 6, and prevent the joint of the filter element assembly 6 in the water purification equipment from being unstable and causing water leakage; at the same time, the positioning member 4 is directly driven by the locking mechanism 3, and there is no need to set up a separate driving device, which is conducive to simplifying the specific design of the installation structure and reducing the volume of the installation structure.

[0022] In practical applications, such as Figure 1 and Figure 4 As shown, when the positioning member 4 is retracted into the top cover 2, this situation at least includes that 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, which indicates that the filter element assembly 6 is installed in place in the water purification device. 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 device 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 in place in the water purification equipment, and the joint of the filter element assembly 6 in the water purification equipment is prone to water 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 protruding length of the end face of the positioning member 4 relative to the end face of the top cover is the largest.

[0023] In some other optional embodiments, the positioning member 4 has a first position and a second position corresponding to the unlocked state and the locked state respectively relative to the top cover 2, and the locking mechanism 3 drives the positioning member 4 to telescopically move relative to the top cover 2 so that the positioning member 4 switches 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 device, and the end surface of the positioning member 4 is retracted relative to the end surface of the top cover or is flush with the end surface of the top cover, that is, the end surface of the positioning member 4 does not protrude from the end surface 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 locking state, at which time the filter element assembly 6 is fixedly installed in the water purification equipment, and the filter element assembly 6 is installed in place, and the end face of the positioning member 4 protrudes from the end face of the top cover.

[0024] In some other optional embodiments, Figure 4 and Figure 5 As shown, the end face of the top cover is set as the top face of the top cover 2, and the top cover 2 is provided with 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 set as a rod-shaped structure adapted to the through hole, which has a simple structure and is easy to implement. In practical applications, the positioning member 4 can be driven by the locking mechanism 3 to move up and down along the through hole relative to the top face to realize the visualization of the installation 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 end face of the top cover. When the positioning member 4 moves up along the through hole relative to the top face through 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 end face of the top cover, it means that the filter element assembly 6 is installed in place. Further, optionally, the through hole is set in the middle of the top cover 2, and the positioning member 4 is set corresponding to the through hole.

[0025] In other optional embodiments, a mark may be provided on the outer peripheral side of the positioning member 4, and the mark may be realized by means of color, pattern, line, etc.; optionally, when the mark is flush with the top end cover, or the mark is exposed from the top end cover, the mark can be seen by people, indicating that the filter element assembly 6 is installed in place.

[0026] In some other optional embodiments, Figure 1As shown, the mounting structure is arranged at one 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 arranged in the filter bottle 61. One end of the filter bottle 61 is provided with a fluid interface 62, and the fluid interface 62 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 arranged at one end of the filter bottle 61 away from the fluid interface 62 to facilitate the rapid disassembly and replacement of the filter element body without removing the entire filter element assembly 6 from the water purification equipment.

[0027] In some other optional embodiments, the locking mechanism 3 may adopt a common filter element locking structure, which can drive the positioning member 4 to telescopically move relative to the top cover 2.

[0028] Embodiment 2: Based on Example 1, Example 2 is another optional implementation of the locking mechanism 3, such as Figure 1 As shown in FIG. 7 , the mounting seat 1 is provided with an accommodating cavity to accommodate the locking mechanism 3, and the locking mechanism 3 includes a first locking block 31 and a second locking block 32 slidably provided in the mounting seat 1, and a driving component 33 provided between the first locking block 31 and the second locking block 32. The mounting seat 1 is provided with 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 is provided with a first opening corresponding to the first slide rail 11, and a second opening corresponding to the second slide rail 12. The driving component 33 drives the first locking block 31 to telescopically move along the first slide rail 11 relative to the mounting seat 1, and the second locking block 32 to telescopically move along the second slide rail 12 relative to the mounting seat 1, so as to switch the locking state and the locking state. The unlocked state; in actual application, the driving component 33 can be used to drive the first locking block 31 and the second locking block 32 to move away from each other in the mounting seat 1, so that the first locking block 31 and the second locking block 32 are respectively extended toward the outside of the mounting seat 1 through the first slide rail 11 and the second slide rail 12, and at this time, the locking mechanism 3 can be switched to the locked state, and at this time, the filter element assembly 6 is fixedly installed in the water purification equipment; the driving component 33 can be used to drive the first locking block 31 and the second locking block 32 to move toward each other in the mounting seat 1, so that the first locking block 31 and the second locking block 32 are respectively retracted toward the mounting seat 1 through the first slide rail 11 and the second slide rail 12, and 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.

[0029] Furthermore, the locking mechanism 3 also includes a reset member disposed in the mounting seat 1, and the reset member is used to push the first locking block 31 and the second locking block 32 to extend outward from the mounting seat 1, so that the locking mechanism is switched to the locked state; specifically, the reset member includes a first reset member 34 and a second reset member 35, the first reset member 34 is disposed between the first locking block 31 and the mounting seat 1, and is used to push the first locking block 31 to extend outward from the mounting seat 1; the second reset member 35 is disposed between the second locking block 32 and the mounting seat 1, used to push the second locking block 32 to extend outward from the mounting seat 1; in actual application, when the user cancels the force applied to the operating member 331, the first locking block 31 and the second locking block 32 can extend outward from the mounting seat 1 through the first resetting member 34 and the second resetting member 35, so that the locking mechanism 3 is converted to the locking state, at which 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, the driving assembly 33 can be driven to reset. In other optional embodiments, the mounting seat 1 is provided with a first mounting column 14 for installing the first resetting member 34 and a second mounting column 15 for installing the second resetting member 35, and the first locking block 31 and the second locking block 32 are both provided with a mounting groove 311 for installing the first resetting member 34 / the second resetting member 35, which has a simple structure and is easy to disassemble and assemble, so as to enhance the connection stability of the first resetting member 34 and the second resetting member 35, thereby enhancing the movement stability of the first locking block 31 and the second locking block 32.

[0030] On the other hand, a first locking hole and a second locking hole corresponding to the first locking block 31 and the second locking block 32 respectively are provided in the water purification equipment. When the locking mechanism 3 is in the locking state, the first locking block 31 is inserted into the first locking hole, and the second locking block 32 is inserted into the second locking hole; when the locking mechanism 3 is in the unlocking state, the first locking block 31 is disengaged from the first locking hole, and the second locking block 32 is disengaged from the second locking hole.

[0031] In some other optional embodiments, the first locking block 31 and the second locking block 32 are symmetrically arranged in the radial direction in the mounting seat 1 , and correspondingly, the first slide rail 11 and the second slide rail 12 are symmetrically arranged in the radial direction in the mounting seat 1 .

[0032] In some other optional embodiments, the moving direction of the positioning member 4 is perpendicular to the moving directions of the first locking block 31 and the second locking block 32 .

[0033] Furthermore, the positioning member 4 is connected to the driving assembly 33, and the driving assembly 33 drives the positioning member 4 to telescopically move 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 inside of the mounting seat 1.

[0034] The optional implementation of the drive assembly 33 is as follows: Figure 2 , 6 As shown in Figures 7 and 8, the driving assembly 33 includes an operating member 331 and a linkage assembly 333 connected to the operating member 331. The positioning member 4 is connected to the linkage assembly 333. The linkage assembly 333 is arranged between the first locking block 31 and the second locking block 32. The operating member 331 is rotatably connected to the mounting seat 1, and at least part of the operating member 331 is exposed outside the top cover 2 for user operation. In actual application, the user can manually rotate the operating member 331, and the linkage assembly 333 is driven to generate linkage through the rotation of the operating member 331 relative to the mounting seat 1, and the first locking block 31 and the second locking block 32 are driven to telescopically move relative to the mounting seat 1 through the linkage assembly 333.

[0035] Further, such as Figure 2 , 6As shown in , 7, one end of the operating member 331 is provided with a driving portion 3313, and one side of the linkage assembly 333 is provided with a transmission rod 332, and the transmission rod 332 extends to be opposite to the driving portion 3313, that is, the transmission rod 332 extends to the rotation path of the driving portion 3313, and the operating member 331 rotates relative to the mounting seat 1, and drives the driving portion 3313 to rotate close to the transmission rod 332, so as to drive the transmission rod 332 to move upward in the mounting seat 1, so that the linkage assembly 333 is linked, so that the locking mechanism is converted from the locked state to the unlocked state; further, the transmission rod 332 extends to the unlocking rotation path of the driving portion 3313, when the filter is disassembled, When the filter element assembly 6 is installed, the operating member 331 is rotated counterclockwise relative to the mounting seat 1, and the driving part 3313 is driven to rotate close to the transmission rod 332, so as to drive the transmission rod 332 to move up in the mounting seat 1, and the first locking block 31 and the second locking block 32 are driven to retract toward the mounting seat 1 through the linkage assembly 333 to achieve the unlocked state. At the same time, the positioning member 4 is driven to extend toward the outside of the top cover 2 through the linkage assembly 333, so that the user can directly observe the installation status of the filter element assembly 6, so as to indicate to the user that the locking mechanism 3 is in the unlocked state; when the filter element assembly 6 is installed, the force applied to the operating member 331 can be cancelled, and the user can directly press the positioning member 4 to make the positioning member 4 The positioning member 4 is retracted relative to the top cover 2, and the linkage assembly 333 is driven to produce linkage through the positioning member 4, so that the first locking block 31 and the second locking block 32 are extended toward the outside of the mounting seat 1 to achieve the locked state of the locking mechanism 3, and when the positioning member 4 is retracted into the top cover 2, it indicates that the filter element assembly 6 is installed in place. At the same time, the linkage assembly 333 can also drive the transmission rod 332 to move downward and reset relative to the mounting seat 1, and drive the driving part 3313 to rotate in the opposite direction and reset through the transmission rod 332, thereby realizing the reset of the operating member 331; or, when the user cancels the force applied to the operating member 331, the first locking block 31 and the second locking block 32 can directly pass through the first locking block 31 and the second locking block 32. 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 directly and automatically ejected to the outside of the mounting seat 1 through the reset member, without the need to separately press the positioning member 4 to move it downward and reset it. Moreover, the first locking block 31 and the second locking block 32 can drive the linkage assembly 333 to produce linkage. The linkage assembly 333 can drive the transmission rod 332 to move downward and reset relative to the mounting seat 1, and drive the driving part 3313 to rotate in the opposite direction and reset it through the transmission rod 332, thereby realizing automatic reset of the operating member 331, making it convenient for users to disassemble and assemble the filter element assembly 6 and easy to operate.

The driving part 3313 is provided at the other end of the rotating shaft 3312. The handle 3311 rotates relative to the mounting base 1 through the rotating shaft 3312 to drive the driving part 3313 to rotate close to the transmission rod 32, and drives the transmission rod 332 to move upward in the mounting base 1 through the driving part 3313; the handle 3311 has a folded position and a disassembled position corresponding to the locked state and the unlocked state respectively; in actual application, the handle 3311 can be rotated around the rotating shaft 3312 relative to the mounting base 1 and the top cover 2 under external force to switch the folded position and the disassembled position of the handle 3311. The disassembly position is as follows: when the filter element assembly 6 is disassembled, the handle 3311 is rotated counterclockwise to the disassembly position by an external force, at which time the handle 3311 is perpendicular to the top cover 2, and the handle 3311 drives the driving part 3313 to rotate synchronously through the rotating shaft 3312, and drives the transmission rod 332 to move upward in the mounting seat 1 through the driving part 3313, and drives the first locking block 31 and the second locking block 32 to retract toward the mounting seat 1 through the linkage assembly 333, and at the same time the positioning member 4 extends out of the top cover 2.
