[0053] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a water purifier filter element with a replaceable core.

[0054] A replaceable filter cartridge for a water purifier includes a mounting base 1 and a housing 2, wherein the mounting base 1 is fixedly connected to the housing 2; and further includes:

[0055] The feed inlet 3 is located on the housing 2; it is used to introduce the water to be purified into the housing 2.

[0056] An ultraviolet lamp 4 is installed inside the housing 2 and fixedly connected to the housing 2; it is used to disinfect water and kill or inhibit the reproduction of bacteria, viruses and other microorganisms in the water.

[0057] Two lifting slots 5 are provided, and the two lifting slots 5 are symmetrically arranged on the housing 2; to provide lifting space for the first elastic mechanism;

[0058] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, two first elastic mechanisms are provided, and the two first elastic mechanisms are disposed within the lifting groove 5; the first elastic mechanism includes:

[0059] Two first springs 10 are provided, and the two first springs 10 are disposed in the lifting groove 5. One end of the first spring 10 is fixedly connected to the housing 2.

[0060] Two lifting plates 11 are provided, and two lifting columns are set in the lifting groove 5. The lifting plate 11 is fixedly connected to the other end of the first spring 10.

[0061] Two button posts 12 are provided, and the two button posts 12 are fixedly installed on the lifting plate 11.

[0062] During operation, pressing the button 12 manually lowers the lifting plate 11, compressing the first spring 10. The lifting plate 11 also pulls the connecting rope 7, causing the retaining plate 15 to move out of the retaining slot 18, thus releasing the installation mechanism and facilitating filter replacement. The release of kinetic energy from the first spring 10 reduces the tension on the retaining plate 15 by the first elastic mechanism, thereby extending the service life of the second spring 14.

[0063] Two movable slots 6 are provided, and the two movable slots 6 are symmetrically arranged on the housing 2; to provide moving space for the second elastic mechanism.

[0064] Reference Figure 4 In a preferred embodiment, two second elastic mechanisms are provided, each disposed within the movable groove 6 and fixedly connected to the housing 2; the second elastic mechanism includes:

[0065] Two fixing plates 13 are provided, and the two fixing plates 13 are disposed in the moving groove 6 and fixedly connected to the housing 2;

[0066] Two second springs 14 are provided, and the two second springs 14 are fixedly mounted on the fixing plate 13;

[0067] Two inclined plates 15 are provided, and the two inclined plates 15 are set on the second spring 14 and fixedly connected to the second spring 14.

[0068] During operation, the connecting rope 7 pulls the inclined plate 15 to move, causing the inclined plate 15 to move out of the slot 18. The inclined plate 15 and the fixing plate 13 also compress the second spring 14. After the installation mechanism is replaced, the second spring 14 releases its elastic potential energy to push the inclined plate 15 to move into the slot 18, thus fixing the installation mechanism.

[0069] A connecting rope 7 is disposed on the first elastic mechanism and fixedly connected to the first elastic mechanism. The connecting rope 7 is also fixedly connected to the second elastic mechanism. One end of the connecting rope 7 is fixedly connected to the lifting plate 11, and the other end of the connecting rope 7 is fixedly connected to the inclined plate 15. It is used to connect the first elastic mechanism and the second elastic mechanism.

[0070] Reference Figures 3 to 5 In a preferred embodiment, the mounting mechanism is disposed on the housing 2 and slidably connected to the housing 2; the mounting mechanism includes:

[0071] Mounting plate 16 is disposed on the housing 2 and slidably connected to the housing 2; mounting plate 16 is used to fix the position of the fixing core 17.

[0072] The fixing core 17 is fixedly mounted on the mounting plate 16; it is used to limit and fix the position of the water purification mechanism.

[0073] Two slots 18 are provided, and the two slots 18 are symmetrically arranged on the mounting plate 16; they are used to cooperate with the second elastic mechanism to fix the mounting plate 16.

[0074] Two handle slots 19 are provided, symmetrically arranged on the mounting plate 16. This facilitates the installation of the mechanism and the water purification mechanism by the staff.

[0075] Reference Figure 5 In a preferred embodiment, a water purification mechanism is disposed on the mounting mechanism; the water purification mechanism includes:

[0076] The adsorption layer 20 is fixedly disposed on the fixed core 17; it is used to adsorb organic matter, odors and other impurities in the water.

[0077] A filter layer 21 is disposed on the adsorption layer 20 and fixedly connected to the adsorption layer 20; it further removes smaller particles.

[0078] The ultrafiltration membrane layer 22 is fixedly disposed on the filter layer 21 and fixedly connected to the fixed core 17.

[0079] Used to filter smaller contaminants;

[0080] Reference Figure 5 In a preferred embodiment, a third elastic mechanism is disposed on the mounting base 1 and fixedly connected to the mounting base 1; the third elastic mechanism includes:

[0081] Multiple third springs 23 are provided, and multiple third springs 23 are fixedly mounted on the mounting base 1;

[0082] The push ring 24 is mounted on the third spring 23 and is fixedly connected to the third spring 23.

[0083] When the inclined plate 15 is removed from the slot 18 during operation, the third spring 23 releases its elastic potential energy to drive the push ring 24 to rise. The push ring 24 drives the fixed core 17 to rise, thereby driving the installation mechanism to rise, making it easier for workers to remove the installation mechanism.

[0084] The discharge port 8 is located on the mounting base 1; it is used for the purified water to flow out.

[0085] Mounting slot 9 is provided on the mounting base 1. It is used to connect the water purifier.

[0086] Working principle: When the filter needs to be replaced, the operator presses button 12, which causes the lifting plate 11 to descend. The lifting plate 11 compresses the first spring 10, and at the same time, the lifting plate 11 pulls the inclined plate 15 out of the slot 18 through the connecting rope 7, releasing the fixation of the installation mechanism. The lifting plate 11 and the fixed plate 13 interact to compress the second spring 14. When the inclined plate 15 moves out of the slot 18, the third spring 23 releases its elastic potential energy, causing the pushing ring 24 to rise. The pushing ring 24 causes the fixed core 17 to rise, and the fixed core 17 causes the installation plate 16 to rise, allowing the operator to easily remove the installation mechanism and the water purification mechanism through the handle slot 19. After replacing the new core, the installation mechanism is put back into the housing 2, the button 12 is released, the first spring 10 returns to its original position, and the connecting rope 7 no longer exerts force on the inclined plate 15. This causes the second spring 14 to release its elastic potential energy, causing the inclined plate 15 to move into the slot 18, thus fixing the new core.

[0087] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
