[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-4 A filter element installation structure includes a filter element cover 1, the interior of the filter element cover 1 is used to install the filter element body 2, a top pressure component 3 is installed at the bottom of the interior of the filter element cover 1, and a positioning component 4 is installed at the top of the interior of the filter element cover 1.

[0025] See Figure 2 Furthermore, the top pressure assembly 3 includes a lifting plate 5 and a turntable 6. The lifting plate 5 is movably installed inside the filter element cover 1 near the bottom. The turntable 6 is movably installed at the bottom of the filter element cover 1. A positioning ring 7 is fixedly installed at the center of the top of the lifting plate 5. Two protruding plates 8 are fixedly installed at the top of the lifting plate 5 and outside the positioning ring 7. A rubber ring 9 is installed on the outer ring of the lifting plate 5. A retaining ring 10 is installed at the top of the turntable 6 and extends through the bottom of the filter element cover 1. A stud 11 is fixedly installed at the center of the top of the turntable 6. A lifting column 12 is installed at the bottom of the lifting plate 5 and outside the stud 11.

[0026] The cross-section of the convex plate 8 is set in a "T" shape, and the outer ring of the rubber ring 9 is located on the inner wall of the filter element cover 1 and fits against each other. When the lifting plate 5 slides up and down through the rubber ring 9, it seals with the inner wall of the filter element cover 1.

[0027] The retaining ring 10 is fixed to the turntable 6. The retaining ring 10 is located inside the filter cover 1 and rotates movably. The turntable 6 is connected to the filter cover 1 and rotates through the retaining ring 10.

[0028] The lifting column 12 has a rectangular cross-section and slides through the bottom of the filter element cover 1. The lifting column 12 is connected to the stud 11 by a thread. When the stud 11 rotates, the lifting column 12 slides up and down through the thread.

[0029] Specifically, rotating the turntable 6 causes the stud 11 to drive the lifting column 12 to slide up and down, which in turn drives the lifting plate 5 to slide up and down. The lifting plate 5 is sealed between the rubber ring 9 and the inner wall of the filter element cover 1. By raising and lowering the lifting plate 5, the top of the filter element body 2 is brought into contact with the water inlet, thereby preventing the bottom of the filter element body 2 from having gaps that allow dirt to pass through.

[0030] Example 2

[0031] See Figure 3 Furthermore, based on Embodiment 1, the positioning component 4 includes an outer positioning ring 13 and an inner positioning ring 14. The outer positioning ring 13 is movably installed on the inner wall of the filter element cover 1, and the inner positioning ring 14 is sleeved on the outside of the filter element body 2. Four support rods 15 are fixedly installed between the outer positioning ring 13 and the inner positioning ring 14. Four guide strips 16 are provided on the inner wall of the top of the filter element cover 1, and four guide grooves 17 are opened on the outer ring of the outer positioning ring 13.

[0032] The outer diameter of the outer positioning ring 13 matches the inner diameter of the top of the filter element cover 1, and the inner diameter of the inner positioning ring 14 is larger than the diameter of the filter element body 2. The outer positioning ring 13 and the support rod 15 are used to support the inner positioning ring 14 and position the top of the filter element body 2 through the inner positioning ring 14.

[0033] The guide bar 16 slides within the guide groove 17, and the outer positioning ring 13 is guided and slidably set through the guide bar 16. The outer positioning ring 13 slides up and down to facilitate disassembly and cleaning of the inside of the filter cover 1.

[0034] Specifically, the outer positioning ring 13 is slidably installed inside the filter element cover 1, and the filter element body 2 is inserted into the inner ring of the inner positioning ring 14. The top of the filter element body 2 is positioned by the inner positioning ring 14 to prevent the filter element cover 1 from shaking or tilting during installation.

[0035] In actual operation, the filter body 2 is installed inside the filter cover 1, and then the filter cover 1 is connected and fixed to the water inlet of the water purification pipe in the household water purifier.

[0036] When adjusting the docking height of the filter element body 2, the rotating turntable 6 causes the stud 11 to rotate, which in turn causes the lifting column 12 to slide up and down, thereby causing the lifting plate 5 to slide up and down, so that the filter element body 2 slides up and down and connects with the water inlet, avoiding gaps between the upper and lower ends of the filter element body 2 that would affect the filtration effect. The lifting plate 5 slides on the inner wall of the filter element cover 1 through the rubber ring 9 and provides a seal. When disassembling and replacing the filter element body 2, the rotating turntable 6 causes the lifting column 12 to slide upward and disengage from the stud 11. The lifting plate 5 is then removed through the protruding plate 8, and the inside of the filter element cover 1 is cleaned.

[0037] During positioning, the outer positioning ring 13 is placed inside the filter element cover 1, and the filter element body 2 is inserted into the inner ring of the inner positioning ring 14. The top of the filter element body 2 is positioned by the inner positioning ring 14 to prevent the filter element body 2 from tilting or shifting during connection and installation. The outer positioning ring 13 is removed to facilitate cleaning of the inside of the filter element cover 1.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
