In addition, the existing filter element is inconvenient to replace and cannot be reused. The present disclosure proposes a structure that protects the filter element and facilitates replacement.

[0024] Example 1

[0025] See also Figure 1 A multi-layer composite mold column filter element includes a shell 1, which is barrel-shaped. In order to ensure that water can radially flow into the shell 1 for purification, water inlet holes 2 are evenly opened on the outer wall of the shell 1, while ensuring that the water is discharged after purification. A water outlet pipe 3 is fixedly connected to the center of the bottom end surface of the inner cavity of the shell 1, and the end of the water outlet pipe 3 extends through the upper part of the shell 1. In order to ensure that water does not leak out, a sealing device 4 is provided on the upper end surface of the shell 1.

[0026] See also Figure 1 In order to purify the moisture entering the shell 1, a second fixing ring 7 is fixedly connected to the bottom end surface of the inner cavity of the shell 1, and the second fixing ring 7 is arranged outside the water outlet pipe 3, and a first fixing ring 6 is arranged outside the second fixing ring 7, and the bottom end surface of the first fixing ring 6 is fixedly connected to the bottom end surface of the inner cavity of the shell 1, and the first fixing ring 6 and the second fixing ring 7 are concentric with the water outlet pipe 3, and through holes 8 are evenly opened on the outer walls of the first fixing ring 6 and the second fixing ring 7.

[0027] See also Figure 2In order to ensure the sealing of the shell 1, effectively prevent water leakage, and facilitate the replacement of the filter element, a sealing device 4 is composed of an end cover 41, a limiting plate 42, a rubber plate 43, a pull ring 44 and a sealing ring 45. An end cover 41 is provided on the upper end surface of the shell 1, and the diameter of the end cover 41 is equal to the diameter of the shell 1. A limiting plate 42 is fixedly connected to the lower end surface of the end cover 41, and the limiting plate 42 matches the inner diameter of the inner cavity of the shell 1. A rubber plate 43 is fixedly connected to the lower end surface of the limiting plate 42, and the rubber plate 43 fits the upper end surfaces of the first fixing ring 6 and the second fixing ring 7. In order to further ensure the sealing of the shell 1, a sealing ring 45 is fixedly connected to the upper part of the inner wall of the inner cavity of the shell 1. In order to facilitate the removal of the end cover 41, pull rings 44 are fixedly connected to the left and right sides of the upper end surface of the end cover 41.

[0028] See also Figure 2 In order to ensure normal drainage of the water outlet pipe 3, the end cover 41, the limit plate 42 and the rubber plate 43 are all provided with openings matching the water outlet pipe 3 at the center. In order to ensure sealing, a rubber ring is fixedly connected to the inner wall of the opening cavity to effectively prevent water loss.

[0029] See also Figure 3 In order to ensure that the water entering the shell 1 can be purified, PP cotton 9 is arranged between the shell 1 and the first fixing ring 6, an activated carbon filter layer 10 is arranged between the first fixing ring 6 and the second fixing ring 7, and a sponge iron essence layer 11 is arranged between the second fixing ring 7 and the water outlet pipe 3. The PP cotton 9 filters larger particles of impurities, the activated carbon filter layer 10 filters micro-particle impurities in the water, and then the sponge iron purification layer 11 purifies the microorganisms in the water.

[0030] See also Figure 2 In order to allow the purified water to enter the water outlet pipe 3, water outlet holes 5 are evenly opened on the outer wall of the water outlet pipe 3 at the lower part of the rubber plate 43, and the aperture of the water outlet hole 5 is smaller than the aperture of the water inlet hole 2 and the through hole 8.

[0031] Example 2

[0032] See also Figure 2 In order to facilitate the staff to take out the end cover 41, a rubber sleeve is bonded to the outer wall of the pull ring 44, and an anti-skid pattern is fixedly connected to the outer wall of the rubber sleeve, which is convenient for the staff to use and effectively avoids hand slipping.

[0033] Working principle: When in use, the shell 1 is placed in water, and water enters the shell 1 through the water inlet hole 2. The water inlet hole 2 effectively prevents larger impurities in the water from entering the shell 1 and protects the filter element at the same time. Water enters between the shell 1 and the first fixed ring 6 through the water inlet hole 2, and filters larger particles of impurities through the PP cotton 9. The water then enters between the first fixed ring 6 and the second fixed ring 7 through the through hole 8 on the outer wall of the first fixed ring 6. The activated carbon filter layer 10 filters the micro-particle impurities in the water. Then the water enters between the second fixed ring 7 and the water outlet pipe 3 through the through hole 8 on the outer wall of the second fixed ring 7. The activated carbon filter layer 10 filters the micro-particle impurities in the water. The purified water then enters the inside of the water outlet pipe 3 through the water outlet hole 5, and is finally discharged from the end of the bucket water outlet pipe 3. When the filter element needs to be replaced, take out the limit plate 42 and the rubber plate 43, and replace the PP cotton 9, the activated carbon filter layer 10 and the sponge iron essence layer 11.
