[0029] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will 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 to be regarded as illustrative in nature and not restrictive.

[0030] See Figures 1 - 5 , which shows a filter element mounting device according to a preferred embodiment of the present utility model, including:

[0031] Filter element 1, on the outer side wall of which there is a first guiding portion 11;

[0032] The casing 2 has an installation cavity 21, an installation opening, and a second guiding portion 22. The installation cavity 21 houses the filter element 1. The installation opening is located at the top of the installation cavity 21 and is in communication with the installation cavity 21. The installation opening allows the filter element 1 to vertically enter and exit the installation cavity 21. The second guiding portion 22 is provided on the side wall of the installation cavity 21 and cooperates with the first guiding portion 11 to guide the filter element 1 to move vertically during the process of inserting the filter element 1 into the installation cavity 21.

[0033] In the filter element installation device of the present utility model, since the first guiding portion 11 is provided on the outer side wall of the filter element 1 and the second guiding portion 22 is provided on the side wall of the installation cavity 21, and the second guiding portion 22 can cooperate with the first guiding portion 11. Therefore, during the process of inserting the filter element 1 into the installation cavity 21 through the installation opening, the first guiding portion 11 and the second guiding portion 22 cooperate to guide the filter element 1 to move vertically along the installation cavity 21, playing a role of positioning and guiding, guiding the filter element 1 to smoothly insert into the installation cavity 21 vertically, avoiding the filter element 1 deviating from its set position in the installation cavity 21 during the process of inserting the filter element 1 into the installation cavity 21, facilitating the quick and correct insertion of the filter element 1 into the installation cavity 21, and improving the installation efficiency.

[0034] See Figure 3 and Figure 5 , in an embodiment, the first guiding portion 11 is provided with a guiding protrusion, and the second guiding portion 22 has a guiding groove 221. The guiding groove 221 is slidably engaged with the guiding protrusion. The guiding groove 221 can play a role in restricting the left - right shaking of the guiding protrusion during the sliding process, can cooperate reliably with the guiding protrusion to guide the filter element 1 to move vertically along the installation cavity 21 smoothly. At the same time, the guiding structure composed of the guiding protrusion and the guiding groove 221 is simple and easy to process, thereby reducing the cost of the filter element installation device.

[0035] In other embodiments, the specific structures of the first guiding portion 11 and the second guiding portion 22 can be interchanged, that is, the first guiding portion 11 has a guiding groove 221, and the second guiding portion 22 has a guiding protrusion.

[0036] Of course, in other embodiments, both the first guiding portion 11 and the second guiding portion 22 can be convex strips extending vertically. Through the slidable cooperation of the two convex strips, it can also achieve guiding the filter element 1 to move vertically during the process of inserting the filter element 1 into the installation cavity 21.

[0037] See Figure 5, in one embodiment, the second guiding portion 22 is further provided with a guiding part 222. The guiding part 222 and the guiding groove 221 are arranged in sequence from top to bottom along the second guiding portion 22, that is, the guiding part 222 is located above the guiding groove 221. The guiding part 222 extends obliquely downward toward the upper end opening of the guiding groove 221. The guiding part 222 is slidably engaged with the guiding protrusion to guide the guiding protrusion to insert into the guiding groove 221. Due to the guiding part 222 extending obliquely downward toward the upper end opening of the guiding groove 221 and the guiding part 222 being able to be slidably engaged with the guiding protrusion, during the process of inserting the filter element 1 into the installation cavity 21, the guiding protrusion abuts against the guiding part 222, so that the guiding protrusion can slide along the guiding part 222 as the filter element 1 moves, and finally inserts into the guiding groove 221 under the guidance of the guiding part 222, playing a role of installation guidance, facilitating the quick guidance of the guiding protrusion to cooperate with the guiding groove 221, and further improving the installation efficiency.

[0038] See Figure 5 , in one embodiment, the number of the guiding parts 222 is two. The two guiding parts 222 are arranged at intervals around the vertical center line of the installation cavity 21, and the two guiding parts 222 enclose a guiding groove. The lower end of the guiding groove communicates with the upper end opening of the guiding groove 221, and the cross-sectional area of the guiding groove gradually increases from bottom to top. In this way, during the process of inserting the filter element 1 into the installation cavity 21, the guiding protrusion can abut against any one of the guiding parts 222 without deliberately aligning the guiding protrusion. At the same time, since the cross-sectional area of the guiding groove gradually increases from bottom to top, the guiding groove forms a conical structure with a larger upper end opening, which is convenient for the guiding protrusion to quickly insert into the guiding groove.

[0039] See Figure 5 , in one embodiment, the lower end of the guiding part 222 extends to the upper end opening of the guiding groove 221, so that the guiding part is connected to the upper end of the guiding groove 221, there is no gap between the lower end of the guiding part 222 and the upper end of the guiding groove 221, and the guiding protrusion slides more smoothly on the guiding part 222 without jamming.

[0040] Of course, in other embodiments, there is a gap between the lower end of the guiding part 222 and the upper end opening of the guiding groove 221, and the gap distance is smaller than the outer diameter of the guiding protrusion, which can also make the guiding protrusion slide more smoothly on the guiding part 222 without jamming.

[0041] In one embodiment, the upper end of the guiding part 222 extends to the installation opening, so that when the guiding protrusion follows the filter element 1 to insert into the installation cavity 21 and is close to the installation opening, it can abut against the guiding part 222, thereby guiding the guiding protrusion to quickly insert and cooperate with the guiding groove 221.

[0042] Of course, in other embodiments, the upper end of the guiding part 222 can be arranged below the installation opening.

[0043] In one embodiment, the lower part of the guiding projection has an arc portion which protrudes downward, and the arc portion is slidably engaged with the guiding portion 222, so that the guiding projection slides more smoothly along the guiding portion 222.

[0044] See Figure 1 and Figure 5 As shown in and, in one embodiment, a connecting portion 23 is provided on the side of the casing 2. The inner side wall of the connecting portion 23 forms a part of the side wall of the installation cavity 21. The above-mentioned second guiding portion 22 is provided on the inner side wall of the connecting portion 23. The outer side wall of the connecting portion 23 is located outside the casing 2, and a protruding portion 24 is provided on the outer side wall of the connecting portion 23. Since the second guiding portion 22 has a guiding groove 221 which is located on the inner side wall of the connecting portion 23, the thickness of the connecting portion 23 is thinned. By providing the protruding portion 24 on the outer side wall of the connecting portion 23, the thickness of the connecting portion 23 can be increased, thereby enhancing the mechanical strength of the connecting portion 23 and avoiding cracking and deformation of the connecting portion 23 caused by the slidable engagement between the guiding groove 221 and the guiding projection, which plays a role in protecting the casing 2. At the same time, since only the protruding portion 24 is provided on the connecting portion 23, the material cost will not be increased too much.

[0045] In one embodiment, the lateral projection of the protruding portion 24 can cover the lateral projection of the second guiding portion 22, so as to effectively support the second guiding portion 22 by using the protruding portion 24, greatly enhancing the structural strength of the connecting portion 23 and making the connecting portion 23 less likely to crack and deform.

[0046] See Figure 1 As shown in, in one embodiment, a handle 3 is provided on the top of the filter element 1. The handle 3 can rotate relative to the filter element 1. The handle 3 has a first position horizontally placed on the filter element 1 and a second position vertically placed on the filter element 1. The handle 3 rotates to switch between the first position and the second position. The handle 3 is used for holding by hand. In this way, by lifting the handle 3, the handle 3 can be driven to rotate, so that the handle 3 can be switched from the first position to the second position, which is convenient for the user to lift the filter element 1, facilitating the installation of the filter element 1 into the installation cavity 21 or the removal of the filter element 1 from the installation cavity 21, making the disassembly and assembly of the filter element 1 more convenient. In addition, when the handle 3 is horizontally placed on the filter element 1, the handle 3 can avoid occupying too much space above the top of the filter element 1, making the overall structure of the filter element 1 more compact.

[0047] See Figure 1 As shown in, in one embodiment, the top of the filter element 1 has a receiving groove 12. When the handle 3 is in the first position, the receiving groove 12 receives the handle 3 to hide the handle 3 in the receiving groove 12, improving the utilization rate of the top space of the filter element 1 and making the overall structure of the filter element 1 more compact.

[0048] See Figure 1, in one embodiment, the top of the filter element 1 further has an operation port 13, and the operation port 13 communicates with the receiving groove 12. The operation port 13 is used for the hand to enter and exit the receiving groove 12, so that the hand can grasp the handle 3 located in the receiving groove 12. The setting of the operation port 13 enables the user's hand to reach into the receiving groove 12, so that the user's hand can easily grasp the handle 3 and lift the handle 3, making it more convenient to use.

[0049] See Figure 4 , in one embodiment, both opposite sides of the top of the filter element 1 have connection holes 14;

[0050] Rotating connection protrusions 31 are provided on both the left and right sides of the handle 3, and each rotating connection protrusion 31 is rotatably engaged with a connection hole 14 in a one-to-one correspondence, ensuring that the handle 3 can rotate relative to the filter element 1 while stably mounting the handle 3 on the filter element 1.

[0051] See Figure 4 , in one embodiment, each rotating connection protrusion 31 has a limiting portion 32, and the limiting portion 32 is provided inside the filter element 1. The limiting portion 32 can abut against the inner wall of the filter element 1 to prevent the rotating connection protrusion 31 from disengaging from the connection hole 14.

[0052] A water purification device provided by a preferred embodiment of the present invention includes the above-mentioned filter element installation device.

[0053] For the water purification device of the present invention, due to the adoption of the above-mentioned filter element installation device, it can also avoid the filter element 1 deviating from its set position in the installation cavity 21 during the process of being inserted into the installation cavity 21, facilitating the quick and correct insertion of the filter element 1 into the installation cavity 21 and improving the installation efficiency.
