[0046] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0047] See Figures 1-11 , which shows a filter element installation device according to a preferred embodiment of the present invention, including:

[0048] A mounting base 1, the mounting base 1 having an accommodation cavity 113;

[0049] A transmission member 2, the transmission member 2 being vertically movably arranged on the mounting base 1;

[0050] A filter element 3, the filter element 3 being separably arranged in the accommodation cavity 113, the filter element 3 being provided with a handle 31 and a first locking part 32, the handle 31 being able to swing up and down relative to the filter element 3, the handle 31 being provided with a first transmission part 311, during the upward swing of the handle 31, the first transmission part 311 can abut against the upper end of the transmission member 2 as the handle 31 swings, so as to push the transmission member 2 to move downward;

[0051] The locking member 4 is rotatably arranged on the mounting base body 1, and the locking member 4 is located at one end close to the bottom wall of the accommodating cavity 113. The locking member 4 is provided with a second locking portion 41 and a second transmission portion 42. The second locking portion 41 has a first working position for cooperating with the first locking portion 32 to limit the filter element 3 in the accommodating cavity 113. The second locking portion 41 further has a second working position for disengaging from the first locking portion 32 so that the filter element 3 can be disengaged from the accommodating cavity 113. The locking member 4 rotates to switch the second locking portion 41 between the first working position and the second working position;

[0052] During the downward movement of the transmission member 2, the second transmission portion 42 abuts against the lower end of the transmission member 2, so that the second transmission portion 42 rotates around the rotation center line of the locking member 4 to push the locking member 4 to switch from the first working position to the second working position.

[0053] The filter element installation device of the present utility model includes an installation base body 1, a transmission member 2, a filter element 3, and a locking member 4. Among them, the installation base body 1 has a receiving cavity 113. The transmission member 2 is vertically movably arranged on the installation base body 1. The filter element 3 is detachably arranged in the receiving cavity 113. The filter element 3 is provided with a handle 31 and a first locking portion 32. The handle 31 can swing up and down relative to the filter element 3, so that the handle 31 can swing upward to be erected on the filter element 3 and can swing downward to be horizontally placed on the filter element 3. When the handle 31 is erected on the filter element 3, the filter element 3 can be conveniently lifted by hand holding the handle 31. When the handle 31 is horizontally placed on the filter element 3, the handle 31 can be stored and placed on the filter element 3. And during the upward swing of the handle 31, the first transmission portion 311 can abut against the upper end of the transmission member 2 as the handle 31 swings, so as to push the transmission member 2 to move downward. The locking member 4 is rotatably arranged on the installation base body 1. The locking member 4 is provided with a second locking portion 41 and a second transmission portion 42. The second locking portion 41 has a first working position that cooperates with the first locking portion 32 to lock the filter element 3, so as to limit the filter element 3 in the receiving cavity 113, thereby realizing reliably locking the filter element 3 on the installation base body 1 and ensuring that the filter element 3 can normally filter the liquid. And the second locking portion 41 also has a second working position that disengages from the first locking portion 32 to unlock the filter element 3, so that the filter element 3 can be separated from the receiving cavity 113, thereby enabling the filter element 3 to be removed from the installation base body 1, facilitating the replacement of the filter element 3 or the maintenance of the filter element 3. The locking member 4 rotates to switch the second locking portion 41 between the first working position and the second working position. And during the downward movement of the transmission member 2, the second transmission portion 42 can abut against the lower end of the transmission member 2 to realize pushing the second transmission portion 42 to rotate around the rotation center line of the locking member 4. The second transmission portion 42 rotates to push the locking member 4 to switch from the first working position to the second working position. That is to say, when disassembling the filter element 3, by lifting the handle 31, the handle 31 swings upward to push the transmission member 2 to move downward. The downward movement of the transmission member 2 can push the second transmission portion 42 to drive. The rotation of the second transmission portion 42 can make the locking member 4 rotate in the first direction, so that the locking member 4 switches from the first working position to the second working position, realizing unlocking the filter element 3 by lifting the handle 31 upward. After unlocking, the filter element 3 can be directly lifted, and the filter element 3 can be disassembled with one hand, with convenient disassembly and high disassembly efficiency. In addition, when installing the filter element 3, hold the handle 31 by hand and insert the filter element 3 into the receiving cavity 113. At the same time, turn the locking member 4 in the second direction, and the second locking portion 41 can be switched from the second working position to the first working position to lock the filter element 3. Whether it is locking or unlocking, only the locking member 4 needs to be turned. Compared with the existing structure of turning the filter element 3 to unlock, the required locking and unlocking torque forces are smaller. Therefore, the user only needs to use less force to lock and unlock the filter element 3, and the locking and unlocking are more labor-saving, which can provide a better use experience for the user.

[0054] The first direction may be a clockwise direction or a counterclockwise direction, and the second direction is opposite to the first direction.

[0055] The opening of the accommodating chamber 113 faces upward, and the filter element 3 vertically enters and exits the accommodating chamber 113 through the opening of the accommodating chamber 113 . The second locking portion 41 cooperates with the first locking portion 32 to limit the filter element 3 from escaping the accommodating chamber 113 upward.

[0056] In one embodiment, the first transmission part 311 is provided with a first inclined portion, which abuts against the upper end of the transmission member 2, and the lower end of the transmission member 2 is provided with a second inclined portion, which abuts against the second transmission part 42, so as to be able to drive the locking member 4 to rotate and unlock.

[0057] See also Figure 2 In one embodiment, the filter element installation device further comprises:

[0058] The first elastic member 5, the lower end of the first elastic member 5 is connected to the mounting base 1, the upper end of the first elastic member 5 is connected to the transmission member 2, and the first elastic member 5 is used to provide a first driving force to the transmission member 2 to limit the transmission member 2 to a state where its lower end is disengaged from the second transmission part 42. In this way, after the transmission member 2 moves downward to unlock the filter element 3, the transmission member 2 can move upward to restore the initial state under the action of the first driving force, that is, the lower end of the transmission member 2 is disengaged from the second transmission part 42, avoiding the random movement of the locking member 4, and improving the locking reliability of the filter element 3. In addition, during the upward swinging of the portable handle 31, the handle 31 abuts against the upper end of the transmission member 2 through the first transmission part 311, and exerts a moving force to overcome the first driving force on the transmission member 2, thereby pushing the transmission member 2 to move downward, so that the lower end of the transmission member 2 can abut against the second transmission part 42, and the locking member 4 is rotated to switch the locking member 4 from the first station to the second station, thereby unlocking the filter element 3.

[0059] See also Figure 2 In one embodiment, the mounting base 1 further has a guide groove 1121, which passes through the mounting base 1 from top to bottom. The transmission member 2 can slidably cooperate with the guide groove 1121 to guide the movement of the transmission member 2, so that the movement of the transmission member 2 is smoother and more stable, thereby improving the structural reliability.

[0060] See also Figures 1-2 In one embodiment, the mounting base 1 comprises:

[0061] The installation body 11 has a receiving cavity 113 and a guide groove 1121, and the guide groove 1121 passes through the outer wall of the installation base 1;

[0062] The positioning member 12 is provided outside the mounting body 11. The positioning member 12 is located at the lateral opening of the guiding groove 1121. The positioning member 12 can abut against the transmission member 2 to limit the transmission member 2 in the guiding groove 1121. In this way, during installation, the transmission member 2 can be inserted into the guiding groove 1121 through the lateral opening of the guiding groove 1121, and then the positioning member 12 is installed on the mounting body 11, so as to stably install the transmission member 2 on the mounting base 1. The installation operation is simple and the installation efficiency is high.

[0063] In one embodiment, the number of the positioning members 12 is multiple. The multiple positioning members 12 are arranged at intervals along the height direction of the mounting body 11. While ensuring that the transmission member 2 is reliably installed on the mounting body 11, it can also help save materials, thereby reducing costs.

[0064] See Figure 2 , in one embodiment, among the multiple positioning members 12, one positioning member 12 has a receiving groove. The first elastic member 5 is arranged in the receiving groove. The lower end of the first elastic member 5 is connected to the bottom wall of the receiving groove. In this way, the receiving groove can be used to install and position the first elastic member 5, so that the first elastic member 5 is reliably connected to the mounting base 1, ensuring that the first elastic member 5 can exert a first driving force on the transmission member 2. At the same time, the receiving groove can also be used to guide the telescopic movement of the first elastic member 5, making the telescopic movement of the first elastic member 5 smooth.

[0065] In one embodiment, the positioning member 12 with the receiving groove is located on one side close to the lower end of the transmission member 2, so that the first elastic member 5 is closer to the lower end of the transmission member 2.

[0066] See Figure 2 , in one embodiment, a connecting protrusion 21 is provided on the outer side wall of the transmission member 2. The lower end of the connecting protrusion 21 is connected to the upper end of the first elastic member 5 to reliably connect the first elastic member 5 and the transmission member 2 together. And the connecting protrusion 21 is slidably matched with the receiving groove to play a role in guiding the movement of the transmission member 2, making the movement of the transmission member 2 smoother.

[0067] In other embodiments, the positioning member 12 can also be a strip-shaped structure extending along the height direction of the mounting body 11.

[0068] In one embodiment, the first elastic member 5 is a spring, so that the first elastic member 5 has better elasticity and structural stability, thereby improving the reset reliability of the transmission member 2.

[0069] In other embodiments, the first elastic member 5 can be an elastic structure such as a spring sheet, as long as it can drive the transmission member 2 to reset.

[0070] SeeFigure 2 , in one embodiment, the filter element mounting device further includes:

[0071] A second elastic member 6, one end of the second elastic member 6 is connected to the mounting base 1, and the other end of the second elastic member 6 is connected to the locking member 4. The second elastic member 6 is configured to provide a second driving force to the locking member 4 so that the locking member 4 is restricted to the first working position. Thus, when installing the filter element 3, the second locking portion 41 rotates to the first working position under the action of the second driving force provided by the second elastic member 6, thereby realizing automatic locking of the filter element 3 without manual operation, making the locking more convenient. At the same time, the second driving force provided by the second elastic member 6 can be used to reliably restrict the second locking portion 41 in the first working position, preventing the second locking portion 41 from randomly disengaging from the first working position and reliably locking the filter element 3. There is no need to additionally provide other structures to lock the locking member 4, which can simplify the structure, facilitate installation, and at the same time reduce the cost of the filter element mounting device, making it more conducive to the popularization and application of the filter element mounting device; when removing the filter element 3, the handle 31 needs to be lifted to push the transmission member 2 downward to apply a rotational force to the locking member 4 to overcome the second driving force of the second elastic member 6, so that the second locking portion 41 rotates to the second working position, and then the filter element 3 can be pulled out from the accommodation cavity 113.

[0072] In one embodiment, the number of the second elastic members 6 is multiple, and the multiple second elastic members 6 are arranged at intervals around the vertical center line of the accommodation cavity 113 to ensure that the locking member 4 can be driven to rotate and reset. At the same time, it ensures that the second locking portion 41 is reliably maintained in the first working position, increasing the locking reliability of the filter element 3 and having higher structural reliability.

[0073] In one embodiment, the second elastic member 6 is a spring, so that the second elastic member 6 has better elasticity and structural stability, thereby improving the reset reliability of the locking member 4.

[0074] In other embodiments, the second elastic member 6 can be an elastic structure such as a spring sheet, as long as it can drive the locking member 4 to reset.

[0075] See Figure 4 , Figures 8-11 , in one embodiment, the second locking portion 41 has a locking groove 411, and the locking groove 411 cooperates with the first locking portion 32. By the cooperation of the locking groove 411 and the first locking portion 32, the contact area between the second locking portion 41 and the first locking portion 32 can be increased, so that the second locking portion 41 is reliably maintained in the first working position, improving the locking reliability of the filter element 3 and having higher structural reliability.

[0076] In other embodiments, the bottom surface of the second locking portion 41 cooperates with the top surface of the first locking portion 32. In this way, the filter element 3 can also be locked.

[0077] In one embodiment, the first locking portion 32 is provided with a first installation guiding inclined surface 321;

[0078] The top of the second locking portion 41 is provided with a second installation guiding inclined surface 412. The second installation guiding inclined surface 412 is slidably engaged with the first installation guiding inclined surface 321 to guide the first locking portion 32 to slide into engagement with the locking groove 411. In this way, during the process of inserting the filter element 3 into the accommodating cavity 113, the first installation guiding inclined surface 321 and the second installation guiding inclined surface 412 are slidably engaged, playing an installation guiding role, making the installation smoother, and improving the installation efficiency of the filter element 3. At the same time, during the sliding engagement process of the first installation guiding inclined surface 321 and the second installation guiding inclined surface 412, the filter element 3 can apply a rotational force to the locking member 4 to overcome the second driving force of the second elastic member 6, causing the second locking portion 41 to switch from the first working position to the second working position, playing a role in avoiding the first locking portion 32, ensuring that the first locking portion 32 can enter the set position of the locking member 4. After the first installation guiding inclined surface 321 disengages from the second installation guiding inclined surface 412, the locking member 4 rotates along the first direction under the second driving force of the second elastic member 6, causing the second locking portion 41 to reset to the first working position, so that the locking groove 411 is engaged with the first locking portion 32, ensuring reliable locking of the filter element 3, and the structural reliability is higher.

[0079] See Figures 10-11 , in one embodiment, the locking member 4 is arranged around the vertical center line of the accommodating cavity 113, so that the locking member 4 forms an annular structure to facilitate increasing the structural stability.

[0080] In one embodiment, the number of the first locking portions 32 is multiple, and the multiple first locking portions 32 are arranged at intervals around the vertical center line of the filter element 3;

[0081] The number of the second locking portions 41 is multiple, and the multiple second locking portions 41 are arranged at intervals around the vertical center line of the accommodating cavity 113. Each second locking portion 41 is respectively engaged with a corresponding first locking portion 32 to enhance the locking reliability of the filter element 3, and the structural reliability is higher.

[0082] See Figures 7-8 , in one embodiment, among the side wall of the accommodating cavity 113 and the outer side wall of the filter element 3, one is provided with a positioning groove 1122, and the other is provided with a positioning protrusion 33. The positioning protrusion 33 is engaged with the positioning groove 1122 to perform installation positioning on the filter element 3, facilitating the quick installation of the filter element 3 in the accommodating cavity 113 and improving the installation efficiency. At the same time, after the filter element 3 is installed in the accommodating cavity 113, the positioning protrusion 33 and the positioning groove 1122 can be used to perform rotational limiting on the filter element 3, preventing the filter element 3 from rotating relative to the installation base 1, and reliably fixing the filter element 3 on the installation base 1.

[0083] See Figure 7 In one embodiment, the positioning groove 1122 is provided on the side wall of the accommodating cavity 113. The cross-sectional area of the upper end of the positioning groove 1122 gradually decreases from top to bottom, so as to guide the positioning protrusion 33 and guide the positioning protrusion 33 to insert into the positioning groove 1122.

[0084] See Figure 11 In one embodiment, the mounting base 1 further has a limiting groove 1111 which is provided on the side wall of the accommodating cavity 113 and is arranged around the vertical center line of the accommodating cavity 113;

[0085] The locking member 4 is further provided with a limiting protrusion 43 which is slidably engaged with the limiting groove 1111 to limit the upward movement of the locking member 4 along the accommodating cavity 113. By providing the limiting groove 1111 on the side wall of the accommodating cavity 113 and the limiting protrusion 43 on the locking member 4, the rotation of the locking member 4 is guided by the sliding fit between the limiting protrusion 43 and the limiting groove 1111, making the rotation of the locking member 4 smoother. At the same time, the upward movement of the locking member 4 along the accommodating cavity 113 can be restricted by the cooperation between the limiting protrusion 43 and the limiting groove 1111, so that the locking member 4 is reliably installed in the accommodating cavity 113, preventing the locking member 4 from randomly disengaging from the set installation position. There is no need to provide a pressing plate on the mounting base 1 to limit the upward movement of the locking member 4, saving a component, simplifying the structure, improving the installation efficiency, and reducing the cost.

[0086] See Figure 11 In one embodiment, the limiting groove 1111 has a laterally extending section 11111 and a mounting opening 11112. The laterally extending section 11111 is slidably engaged with the limiting protrusion 43 to limit the upward movement of the locking member 4 along the accommodating cavity 113. The mounting opening 11112 communicates with the laterally extending section 11111 and is for the limiting protrusion 43 to vertically enter and exit the laterally extending section 11111;

[0087] The filter element mounting device further includes:

[0088] The limiting part 131 is provided on the mounting base 1. At least part of the limiting part 131 is located in the limiting groove 1111. The limiting part 131 can abut against the limiting protrusion 43 to limit the limiting protrusion 43 in the lateral extension section 11111. In this way, during the process of installing the locking member 4 into the accommodating cavity 113, the limiting protrusion 43 can be aligned with the installation opening 11112. Then, the locking member 4 is pushed downward to the lateral extension section 11111. Finally, the locking member 4 is rotated to drive the limiting protrusion 43 to move to one end of the lateral extension section 11111 away from the installation opening 11112, and the installation can be completed. The installation operation is convenient. At the same time, during the process of the limiting protrusion 43 rotating with the locking member 4 and approaching the installation opening 11112, the limiting protrusion 43 can abut against the limiting part 131, playing a role in blocking the limiting protrusion 43 from sliding into the installation opening 11112, thereby restricting the limiting protrusion 43 from passing through the installation opening 11112 and disengaging from the limiting groove 1111, enabling the limiting protrusion 43 to cooperate reliably with the lateral extension section 11111, and improving the structural reliability and stability.

[0089] See Figure 11 , in an embodiment, the limiting groove 1111 further has a vertical extension section 11113. The lower end of the vertical extension section 11113 is communicated with one side of the top of the lateral extension section 11111, and the upper end of the vertical extension section 11113 is communicated with the installation opening 11112. This vertical extension section 11113 can increase the distance between the installation opening 11112 and the lateral extension section 11111 to increase the difficulty of the limiting protrusion 43 sliding into the installation opening 11112, and improve the connection reliability between the limiting groove 1111 and the limiting protrusion 43.

[0090] See Figure 11 , in an embodiment, the cross-sectional area of the upper end of the vertical extension section 11113 gradually increases from bottom to top, that is, the vertical cross-section of the upper end of the vertical extension section 11113 is conical, which can play a role in guiding the installation of the limiting protrusion 43 to guide the limiting protrusion 43 to be smoothly installed into the limiting groove 1111, improve the installation smoothness of the locking member 4, and make the installation of the locking member 4 more convenient.

[0091] In an embodiment, the mounting base 1 includes:

[0092] A mounting main body 11, the mounting main body 11 has an accommodating cavity 113 and a limiting groove 1111;

[0093] The waterway adapter 13 is provided at the bottom of the installation main body 11, and the waterway adapter 13 is provided with the above-mentioned limiting portion 131. That is, the installation base 1 is composed of the separately arranged installation main body 11 and the waterway adapter 13. The manufacturing difficulty of this installation base 1 is lower, and it is convenient for assembly. At the same time, by arranging the limiting portion 131 on the waterway adapter 13, the utilization rate of the waterway adapter 13 can be improved, the need for additional configuration of limiting parts can be eliminated, the number of parts can be reduced, thereby simplifying the structure, which is beneficial to further improving the installation efficiency. At the same time, it is also beneficial to further reduce costs.

[0094] See Figure 11 , in an embodiment, the installation base 1 further has a positioning groove 1112, the positioning groove 1112 is provided on the bottom wall of the accommodation cavity 113, and the positioning groove 1112 is arranged around the rotation center line of the locking member 4;

[0095] The bottom of the locking member 4 is provided with an annular positioning portion 44, and the annular positioning portion 44 is slidably matched with the positioning groove 1112. In this way, through the cooperation of the annular positioning portion 44 and the positioning groove 1112, on the one hand, it can play a role in installation positioning, facilitating the quick installation of the locking member 4 into the accommodation cavity 113, and on the other hand, it can play a role in rotation guiding, making the rotation of the locking member 4 smoother.

[0096] See Figure 6 , in an embodiment, the installation base 1 further has a first water flow passage 114, the upper end of the first water flow passage 114 extends above the bottom wall of the accommodation cavity 113, and the lower end of the first water flow passage 114 is used to communicate with a water supply device or a water using device;

[0097] The filter element 3 has a raw water cavity, a purified water cavity and a second water flow passage 34, and the second water flow passage 34 communicates with the raw water cavity or the purified water cavity;

[0098] The filter element installation device further includes:

[0099] A first elastic water stop structure 7, the first elastic water stop structure 7 is vertically movably arranged on the first water flow passage 114, the first elastic water stop structure 7 has a first water stop position for closing the first water flow passage 114 and a first communication position for opening the first water flow passage 114, and the first elastic water stop structure 7 can maintain the first water stop position under its own elastic action;

[0100] A second elastic water stop structure 8, the second elastic water stop structure 8 is vertically movably arranged in the second water flow passage 34, the second elastic water stop structure 8 has a second water stop position for closing the second water flow passage 34 and a second communication position for opening the second water flow passage 34, and the second elastic water stop structure 8 can maintain the second water stop position under its own elastic action;

[0101] During the process of installing the filter element 3 on the installation base 1, the lower end of the second elastic water stop structure 8 abuts against the upper end of the first elastic water stop structure 7, so that the first elastic water stop structure 7 is switched from the first water stop position to the first communication position under the thrust of the second elastic water stop structure 8, and the second elastic water stop structure 8 is switched from the second water stop position to the second communication position under the thrust of the first elastic water stop structure 7, so as to connect the second water flow channel 34 and the first water flow channel 114.

[0102] In this way, when the filter element 3 is installed on the installation base 1, the lower end of the second elastic water stop structure 8 can abut against the upper end of the first elastic water stop structure 7, so that the first elastic water stop structure 7 is switched from the first water stop position to the first communication position under the thrust of the second elastic water stop structure 8, realizing the opening of the first water flow channel 114, enabling the first water flow channel 114 to communicate with the water supply device or the water using device. At the same time, the second elastic water stop structure 8 is switched from the second water stop position to the second communication position under the thrust of the first elastic water stop structure 7, realizing the opening of the second water flow channel 34, enabling the second water flow channel 34 to communicate with the raw water chamber or the purified water chamber. At the same time, the second water flow channel 34 is connected to the first water flow channel 114, so that the water supply device is connected to the raw water chamber, and the raw water output by the water supply device is transported to the filter element 3, or the water using device is connected to the purified water device, and the purified water prepared by the filter element 3 is output to the water using device for use, realizing the opening of the first water flow channel 114 and the second water flow channel 34 during the installation process. The waterway connection is convenient, there is no need for a controller to control the opening of the first water flow channel 114, which saves more power, is not affected by power failure, and has higher connection reliability; when disassembling the filter element 3, the filter element 3 is removed from the installation base 1, the second elastic water stop structure 8 is separated from the first elastic water stop structure 7, and the second elastic water stop structure 8 returns to the second water stop position from the second communication position under its own elastic action to reliably seal the second water flow channel 34 and achieve water stop. At the same time, the first elastic water stop structure 7 is switched from the first communication position to the first water stop position under its own elastic action to reliably seal the first water flow channel 114 and achieve water stop, realizing the closing of the first water flow channel 114 and the second water flow channel 34 during the disassembly process. There is no need for a controller to control the closing of the first water flow channel 114, which saves more power, is not affected by power failure, and has higher water stop reliability.

[0103] See Figure 6 , in an embodiment, the first elastic water stop structure 7 includes:

[0104] A first water stop base 71, which is vertically movably arranged on the first water flow channel 114;

[0105] The first water-stop elastic member 72, the lower end of the first water-stop elastic member 72 is connected to the installation base 1, and the upper end of the first water-stop elastic member 72 is connected to the first water-stop base 71;

[0106] The first sealing ring 73 is arranged on the first water-stop base 71. When the first elastic water-stop structure 7 is in the first water-stop working position, the first sealing ring 73 abuts against the first water flow channel 114 to close the first water flow channel 114. When the first elastic water-stop structure 7 is in the first communication working position, the first sealing ring 73 is disengaged from abutting against the first water flow channel 114 and is in clearance fit with the first water flow channel 114 to open the first water flow channel 114. In this way, when the first water-stop base 71 moves upward to the first water-stop working position, the first sealing ring 73 abuts against the first water flow channel 114, so that the first elastic water-stop structure 7 is in close contact with the first water flow channel 114, reliably sealing the gap between the first elastic water-stop structure 7 and the first water flow channel 114 to avoid water leakage. When the first water-stop base 71 moves downward to the first communication working position, the first sealing ring 73 is disengaged from abutting against the first water flow channel 114, and the first sealing ring 73 is in clearance fit with the first water flow channel 114 to ensure that the first water flow channel 114 can be opened.

[0107] See Figure 6 , in an embodiment, the first water flow channel 114 has a tapered section 1141, and the cross-section of the tapered section 1141 gradually decreases from bottom to top. The first sealing ring 73 can abut against the tapered section 1141. In this way, when the first elastic water-stop structure 7 moves upward to the first water-stop working position, the first sealing ring 73 abuts against the tapered section 1141 to reliably close the first water flow channel 114. At the same time, by abutting the first sealing ring 73 against the tapered section 1141, a limiting effect on the first elastic water-stop structure 7 is achieved, and the first elastic water-stop structure 7 can be restricted on the first water flow channel 114 to prevent the first elastic water-stop structure 7 from detaching from the first water flow channel 114.

[0108] In other embodiments, the first water flow channel 114 can be divided into an upper section and a lower section, and a stepped end face is formed between the upper section and the lower section. The first sealing ring 73 abuts against the stepped end face to close the first water flow channel 114.

[0109] See Figure 6, in one embodiment, the outer sidewall of the first water stop base body 71 is provided with an abutting portion, the abutting portion is located above the first sealing ring 73, the outer diameter of the abutting portion gradually decreases from bottom to top, and the abutting portion can abut against the tapered section 1141 to limit the first elastic water stop structure 7 on the first water flow channel 114. In this way, when the first elastic water stop structure 7 moves upward to the first water stop working position, by abutting the abutting portion against the tapered section 1141, on the one hand, the first elastic water stop structure 7 can be reliably restricted from separating from the first water flow channel 114, improving the connection reliability between the first elastic water stop structure 7 and the installation base body 1. On the other hand, a certain sealing effect can be achieved by the abutting of the abutting portion against the tapered section 1141, thereby improving the water stop reliability.

[0110] See Figure 6 , in one embodiment, the first water stop base body 71 has a water passage 711, the water passage 711 is located above the first sealing ring 73, the lower end of the water passage 711 penetrates the outer sidewall of the first water stop base body 71, the lower end of the water passage 711 penetrates the upper end of the first water stop base body 71. When the first elastic water stop structure 7 is in the first communication working position, the lower end of the water passage 711 communicates with the first water flow channel 114, and the upper end of the water passage 711 communicates with the second water flow channel 34. In this way, when the first elastic water stop structure 7 and the second elastic water stop structure 8 abut against each other, and the first elastic water stop structure 7 is in the first communication working position and the second elastic water stop structure 8 is in the second communication working position, the first water flow channel 114 and the second water flow channel 34 can be communicated through the water passage 711. Among them, since the water passage 711 is provided on the first water stop base body 71, the cross-sectional area of the water passage 711 can be made close to the cross-sectional area of the first water stop base body 71, which can improve the water flow rate and thus improve the water inlet and outlet efficiency.

[0111] In other embodiments, the above-mentioned water passage 711 can also be provided between the outer sidewall of the first water stop base body 71 and the first water flow channel 114.

[0112] See Figure 6 , in one embodiment, the filter element 3 is provided with a second sealing ring 35, and the second sealing ring 35 is located on one side close to the lower end of the second water flow channel 34;

[0113] When the second elastic water stop structure 8 is in the second water stop working position, the second elastic water stop structure 8 abuts against the second sealing ring 35 to close the second water flow channel 34. When the second elastic water stop structure 8 is in the second communication working position, the second elastic water stop structure 8 disengages from the second sealing ring 35 to open the second water flow channel 34;

[0114] The installation base 1 is provided with an annular convex portion 1113, and the annular convex portion 1113 is arranged around the upper end of the second water flow passage 34. When the first elastic water stop structure 7 is in the first communication working position, at least a part of the annular convex portion 1113 is inserted into the second sealing ring 35 and is in interference fit with the second sealing ring 35. In this way, the second elastic water stop structure 8 can be abutted against the second sealing ring 35 to seal the gap between the second elastic water stop structure 8 and the second sealing ring 35, so as to reliably close the second water flow passage 34, and the water stop reliability is higher. In addition, when the first water flow passage 114 and the second water flow passage 34 are communicated, the gap between the installation base 1 and the filter element 3 can be reliably sealed through the interference fit between the annular convex portion 1113 and the second sealing ring 35, and the water leakage problem during the use of the filter element 3 can be effectively avoided.

[0115] See Figure 3 , in an embodiment, the second elastic water stop structure 8 includes:

[0116] A second water stop base 81, which is vertically movably arranged on the second water flow passage 34. When the second elastic water stop structure 8 is in the second water stop working position, the second water stop base 81 abuts against the second sealing ring 35 to close the second water flow passage 34. When the second elastic water stop structure 8 is in the second communication working position, the second water stop base 81 is disengaged from the second sealing ring 35 to open the second water flow passage 34;

[0117] A second water stop elastic member 82, the upper end of the second water stop elastic member 82 is connected to the filter element 3, and the lower end of the second water stop elastic member 82 is connected to the second water stop base 81. In this way, the second water stop elastic member 82 provides a driving force for the second water stop base 81 to reliably abut the second water stop base 81 and the second sealing ring 35 together, so that the second elastic water stop structure 8 is reliably maintained in the second water stop working position, with high structural reliability, simple and practical structure, and low cost.

[0118] See Figure 9 , in an embodiment, the side wall of the second water flow passage 34 has a plurality of water inlets 341, the water inlets 341 are located above the second sealing ring 35, the water inlets 341 communicate with the raw water chamber or the purified water chamber, and the plurality of water inlets 341 are arranged in sequence around the vertical center line of the second water flow passage 34. Since the water inlets 341 are arranged on the side wall of the second water flow passage 34, the water flow rate can be increased, and thus the water inlet and outlet efficiency can be improved.

[0119] In other embodiments, the above water inlets 341 may be provided at the upper end of the second water flow passage 34.

[0120] In one embodiment, both the first water-stop elastic member 72 and the second water-stop elastic member 82 are springs. Of course, in other embodiments, the first water-stop elastic member 72 and the second water-stop elastic member 82 can also be elastic structures such as elastic sheets.

[0121] In one embodiment, for convenient installation, the installation base 1 includes a water path adapter 13, a base 111, and a main housing 112. The water path adapter 13 is provided at the bottom of the base 111. The water path adapter 13 has a water inlet, and the water inlet communicates with the lower end of the first water flow channel 114. The water inlet is also used to communicate with a water supply device or a water using device. The main housing 112 is provided on the top of the base 111, and the main housing 112 and the base 111 enclose the above-mentioned accommodation cavity 113.

[0122] A preferred embodiment of the present utility model provides a water purification device, including the above-mentioned filter element installation device.

[0123] For the water purification device of the present utility model, due to the adoption of the above-mentioned filter element installation device, the locking and unlocking torque forces of the filter element 3 can also be reduced. Therefore, the user only needs to use less force to lock and unlock the filter element 3, and the locking and unlocking are more labor-saving, which can provide a better user experience for the user. At the same time, it can also achieve single-handed disassembly, and the disassembly is more convenient.
