[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 An activated carbon filter element is shown, comprising:

[0022] A housing 1, a filter element main body 12 is installed inside the housing 1, a water inlet seat 2 is arranged at the upper end of the housing 1, and a water outlet seat 3 is arranged at the lower end of the housing 1;

[0023] A buffer mechanism is provided inside the filter element body 12;

[0024] The buffer mechanism includes a filter cartridge 8, which is installed on the inner wall of the filter element body 12. A storage cavity 9 is opened inside the filter cartridge 8. A water delivery hole 10 is opened on the filter cartridge 8, and the water delivery hole 10 and the storage cavity 9 are connected to each other. Activated carbon particles 13 are arranged in the storage cavity 9. A filter element is arranged at the upper end of the filter cartridge 8. The filter element includes a filter grid seat 5. A water inlet mesh cover 4 is installed at the upper end of the filter grid seat 5. A filter sponge 6 is installed at the lower end of the filter grid seat 5. The filter grid seat 5 is connected to the filter cartridge 8 through the filter sponge 6. A sealing ring 7 is installed on the inner wall of the water inlet seat 2. The water inlet seat 2 is threadedly connected to the shell 1, and the sealing ring 7 is located at the connection between the water inlet seat 2 and the shell 1.

[0025] The filter cartridge 8 is inserted into the inner wall of the filter element body 12, and water transfer holes 10 are provided on the inner and outer walls of the filter cartridge 8. The storage chamber 9 provided inside the filter cartridge 8 is connected to the water transfer hole 10, and the inner walls of the storage chamber 9 and the water transfer hole 10 are filled with activated carbon particles 13. When the water slides through the water inlet at the upper end of the water inlet seat 2, small gaps are formed between the stacked activated carbon particles 13. The water passing through the small gaps increases the path of the fluid and improves the filtering effect of the water. The filter grid seat 5 plays a role in filtering large granular impurities to prevent large granular impurities from flowing downstream to the filter cartridge 8, causing the water transfer hole 10 to be blocked. The upper and lower outer walls of the shell 1 are provided with threaded surfaces, and the water inlet seat 2 and the water outlet seat 3 are both connected to the shell 1 by threads.

[0026] A mounting seat 16 is installed at the bottom of the water outlet seat 3, and springs 15 are equidistantly arranged on the upper end of the mounting seat 16. A support ring 14 is installed on the upper end of the spring 15. The water outlet seat 3 is threadedly connected to the lower end of the shell 1, and the lower end of the filter cartridge 8 is overlapped with the upper end of the support ring 14. A water outlet hole 11 is opened at the lower end of the filter cartridge 8.

[0027] When installing the filter element main body 12, manually squeeze the filter cartridge 8 downward to the specified position, rotate and twist the water inlet seat 2, and install the water inlet seat 2 and the upper end of the shell 1 as a whole. If the filter element main body 12 needs to be replaced later, it is only necessary to open the water inlet seat 2, and the filter element main body 12 and the filter cartridge 8 are pushed upward by the spring 15, and the filter element main body 12 and the filter cartridge 8 are pushed out of the shell 1, so that the filter element main body 12 can be manually taken out for replacement.

[0028] Working principle of this utility model:

[0029] By installing the filter cartridge 8 on the inner wall of the activated carbon granules 13, the activated carbon granules 13 are filled inside the storage chamber 9 opened in the filter cartridge 8, and the activated carbon granules 13 are also filled on the inner wall of the filter cartridge 8. At this time, the water flow path is intercepted in turn by the activated carbon granules 13 at the storage chamber 9 and the inner wall of the filter cartridge 8. The stacked activated carbon granules 13 are used to increase the water flow path and improve the filtering effect of the water body. The filter element main body 12 is connected to the filter cartridge 8, and the bottom of the filter cartridge 8 is overlapped by the support ring 14. When installing the filter element main body 12, the filter cartridge 8 is manually squeezed downward to the specified position, and the water inlet seat 2 is rotated and twisted to install the water inlet seat 2 and the upper end of the shell 1 as a whole. If the filter element main body 12 needs to be replaced later, it is only necessary to open the water inlet seat 2. The filter element main body 12 and the filter cartridge 8 are pushed upward by the spring 15, and the filter element main body 12 and the filter cartridge 8 are pushed out of the shell 1, so that it is convenient to manually take out the filter element main body 12 for replacement.
