For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0032] The utility model relates to a filter element seat for fixing a filter element.

[0033] Specifically, refer to Figure 1-5 , comprising: a filter cartridge seat body 1, a filter cartridge body 2 detachably connected to the filter cartridge seat body 1, and a disassembly assembly 3 arranged in the filter cartridge seat body 1 for disassembling and assembling the filter cartridge body 2. To facilitate the connection of the filter cartridge body 2 to generate filtered water, a water channel component 4 is connected to the filter cartridge seat body 1, and the water channel component 4 extends upward into the filter cartridge seat body 1, and the central axis of the water channel component 4 coincides with the central axis of the filter cartridge seat body 1;

[0034] The disassembly and assembly component 3 includes a rotating gear ring 301 rotatably set in the filter cartridge seat body 1, and a plurality of guide grooves 302 are opened on the rotating gear ring 301. The plurality of guide grooves 302 are evenly spaced and arranged in a circular array with the center of the filter cartridge seat body 1 as the center. To facilitate the sliding of the guide rod 303, the guide groove 302 is arc-shaped, and a guide rod 303 is slidably set in the guide groove 302. A slide plate 304 is connected to the guide rod 303, and the slide plate 304 is slidably connected in the filter cartridge seat body 1. A plurality of sliding openings adapted to the slide plate 304 are opened on the filter cartridge seat body 1, and a positioning block 305 is connected to one side of the slide plate 304. When the plurality of positioning blocks 305 move to a certain position with the slide plate 304, the plurality of positioning blocks 305 form a ring, and a driving gear 306 meshing with the rotating gear ring 301 is rotatably set in the filter cartridge seat body 1.

[0035] Preferably, a sealing ring 5 is bonded to the filter cartridge seat body 1, and the sealing ring 5 is used to improve the sealing effect of the filter cartridge seat body 1, and the diameter of the sealing ring 5 can be selected in a variety of ways according to the diameter of the filter cartridge body 2. It is only necessary to ensure the sealing of the connection between the filter cartridge seat body 1 and the filter cartridge body 2. The number of positioning blocks 305 is not limited and can be set to three, four, five or more, as long as they are distributed in a circular array with equal spacing around the center of the filter cartridge seat body 1.

[0036] The filter element body 2 is inserted into the filter element seat body 1 for preliminary positioning, and then the driving gear 306 is rotated to drive the rotating gear ring 301 to rotate. While the rotating gear ring 301 rotates, the guide groove 302 provided thereon drives the guide rod 303 to slide. At this time, the slide plate 304 connected to the guide rod 303 can drive the positioning block 305 to move toward the center of the filter element seat body 1, thereby positioning the filter element body 2. The provision of the disassembly and assembly component 3 not only facilitates the rapid disassembly and assembly of the filter element body 2, but also can be adapted to filter element bodies 2 of various diameters, with a wider range of applications.

[0037] Specifically, refer to Figure 2 and Figure 4 The filter element seat body 1 is connected to a mounting frame 7 , the driving gear 306 is connected to a rotating shaft 6 , and one end of the rotating shaft 6 passes through the mounting frame 7 and extends to the outside of the mounting frame 7 .

[0038] The rotating shaft 6 is provided to facilitate the user to rotate the external driving gear 306 of the filter element seat body 1, so as to better facilitate the user to apply force. Example

[0039] Based on Example 1, refer to Figure 2 and Figure 4 A locking assembly 8 for locking the rotating shaft 6 is provided on the rotating shaft 6, and the locking assembly 8 includes a mounting seat 801 symmetrically connected to the rotating shaft 6, and a connecting plate 802 is rotatably connected to the mounting seat 801, and a mounting groove is provided on the mounting seat 801, and a short-circuit rod is connected in the mounting groove, and the connecting plate 802 is rotatably connected to the short-circuit rod, and one side of the connecting plate 802 is connected to a limiting block 803, and the limiting block 803 is tightly fitted with the inner wall of the mounting frame 7. In order to improve the friction coefficient between the limiting block 803 and the mounting frame 7 and improve the positioning effect of the rotating shaft 6, an anti-slip pattern is integrally formed on the inner wall of the mounting frame 7, and anti-slip particles are integrally formed on the side of the limiting block 803 opposite to the inner wall of the mounting frame 7, and the anti-slip particles conflict with the inner wall of the mounting frame 7, and a telescopic spring 804 is connected to the side of the connecting plate 802 away from the limiting block 803, and the other end of the telescopic spring 804 is connected to the rotating shaft 6.

[0040] After the filter element body 2 is positioned, in order to avoid the reversal of the rotating shaft 6 and the unstable fixation of the filter element body 2, a locking assembly 8 is designed to avoid this situation. When the rotating shaft 6 needs to be rotated, one end of the connecting plate 802 is pressed to move one end of the connecting plate 802 to the side away from the rotating shaft 6. At this time, the other end of the connecting plate 802 squeezes the telescopic spring 804 and no longer conflicts with the inner wall of the mounting frame 7. At this time, the rotating shaft 6 can be rotated. Similarly, when the rotating shaft 6 does not need to be rotated, the elastic force of the telescopic spring 804 can drive the limit block 803 to conflict with the inner wall of the mounting frame 7 for locking.

[0041] Specifically, refer to Figure 4 A support plate 10 is rotatably connected to the rotating shaft 6. The top of the connecting plate 802 extends to the outside of the mounting frame 7 and is connected to a mounting block 9. A groove matching the support plate 10 is formed on the mounting block 9.

[0042] When rotating the shaft 6, in order to free the user's fingers and eliminate the need for the user to press the two connecting plates 802 for a long time with his hands, the user can first press the connecting plate 802, and then rotate the support plate 10 so that the support plate 10 rotates 90°, so that the support plate 10 contacts the groove opened on the mounting block 9.

[0043] A filter element comprises a filter element body 2. A limiting groove 11 is provided on the filter element body 2. The limiting groove 11 is annular and the size of the limiting groove 11 is adapted to that of a positioning block 305.

[0044] The provided limiting groove 11 is convenient for use in conjunction with the positioning block 305 , so that the positioning block 305 can be better utilized to fix the filter element body 2 .

[0045] Working principle: When the filter element body 2 needs to be fixed:

[0046] The filter element body 2 is inserted into the filter element seat body 1 for preliminary positioning, and then the driving gear 306 is rotated to drive the rotating gear ring 301 to rotate. While the rotating gear ring 301 rotates, the guide groove 302 provided thereon drives the guide rod 303 to slide. At this time, the slide plate 304 connected to the guide rod 303 can drive the positioning block 305 to move to the center of the filter element seat body 1, so as to position the filter element body 2. The setting of the disassembly and assembly component 3 not only facilitates the rapid disassembly and assembly of the filter element body 2, but also can be adapted to filter element bodies 2 of various diameters, with a wider range of applications;

[0047] When the rotating shaft 6 needs to be locked:

[0048] When it is necessary to rotate the rotating shaft 6, one end of the connecting plate 802 is pressed to move the one end of the connecting plate 802 away from the rotating shaft 6. At this time, the other end of the connecting plate 802 squeezes the telescopic spring 804 and no longer conflicts with the inner wall of the mounting frame 7. At this time, the rotating shaft 6 can be rotated. Similarly, when it is not necessary to rotate the rotating shaft 6, the elastic force of the telescopic spring 804 can drive the limit block 803 to conflict with the inner wall of the mounting frame 7 for locking.

[0049] The above description is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical contents suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
