DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 3 A novel refrigerator filter element in this embodiment includes an upper shell 2 and a lower shell 3, and carbon rod assemblies are arranged inside the upper shell 2 and the lower shell 3.

[0025] The carbon rod assembly includes an activated carbon rod 1, a carbon rod upper cover 4 and a carbon rod lower cover 5. The carbon rod upper cover 4 is connected to the upper shell 2, and the carbon rod lower cover 5 is fixed to the inner wall of the lower shell 3. The structural characteristics of the carbon rod upper cover 4 enable the filter element to play a water isolation role during the filtration process. There is no need to worry about water that has not been filtered by the filter element being directly output from the water outlet 16. The activated carbon rod 1 is mounted between the opposite sides of the carbon rod upper cover 4 and the carbon rod lower cover 5.

[0026] A snap-fit ​​device is also provided on the upper side of the upper shell 2, and the snap-fit ​​device includes a female snap 9, a snap shell 10, a male snap 11, a jump key 12 and a spring 13. The female snap 9 is fixed to the upper side of the upper shell 2, the snap shell 10 is mounted on the outside of the female snap 9, the male snap 11 is slidably connected to the inside of the female snap 9, a groove is provided on the outside of the male snap 11, and the jump key 12 is slidably connected to the inner wall of the groove, one end of the spring 13 is fixed to the side of the jump key 12 facing away from the male snap 11, and the other end of the spring 13 is connected to the inner wall of the groove, and the jump key 12 and the spring 13 cooperate with each other.

[0027] It should be noted that when the male buckle 11 is pressed down, the inverted buckles set at both ends of the top of the male buckle 11 will stretch the two features on the upper end of the female buckle 9 to the left and right, and the spring 13 will also be compressed as the male buckle 11 is pressed down. The jump key 12 set in the groove on one side of the male buckle 11 slides in the limiting groove slide rail on the inner side of the buckle shell 10 in the direction of the male buckle 11 being pressed down. When it reaches the bottom, the jump key 12 rotates, and its feature is stuck at the bottom of the groove slide rail on the inner side of the buckle shell 10. At this time, the buckle assembly is in an open state; when the male buckle 11 is pressed down again, the jump key 12 can be rotated back into the slide rail on the inner side of the buckle shell 10. At this time, the spring 13 generates elastic force to push the male buckle 11 back to its original position. The rebound of the male buckle 11 can also drive the jump key 12 back to its original position, and the two features on the upper end of the female buckle 9 are closed. At this time, the buckle assembly is in a clamped state.

[0028] In this embodiment, a water inlet 14 and a water outlet 16 are provided on the upper side of the upper shell 2, and a protective cover 6 is provided on the outside of the water inlet 14 and the water outlet 16. The water inlet 14 is connected to an input water pipe, and the water outlet 16 is connected to an output water pipe. When the filter element is used in the water treatment equipment, it is only necessary to remove the protective cover 6, connect the input water pipe to the water inlet 14, and connect the output water pipe to the water outlet 16. The water flows into the filter element through the water inlet 14. After the water flows into the wading cavity 15, it is filtered by the activated carbon rod 1 and then flows out from the water outlet 16, and the filtration work is completed.

[0029] In this embodiment, a water-wading cavity 15 is opened inside the activated carbon rod 1. Water is input into the refrigerator filter element from the water inlet 14. After reaching the water-wading cavity 15, it is filtered by the built-in activated carbon rod 1 and flows out from the water outlet 16. Two first O-rings 7 are installed between the carbon rod upper cover 4 and the opposite side of the upper shell 2. The water inlet 14 and the water outlet 16 in the upper shell 2 adopt a novel appearance design. This design scheme can ensure a certain water flow rate and flow rate.

[0030] In this embodiment, the inner walls of the two protective covers 6 and the outer sides of the water inlet 14 and the water outlet 16 are both covered with second O-rings 8, and the inner wall of the buckle shell 10 is fixed with a groove slide rail.

[0031] The working principle of the above embodiment is:

[0032] (1) Water enters the refrigerator filter element from the water inlet 14, reaches the water cavity 15, is filtered by the built-in activated carbon rod 1, and then flows out from the water outlet 16.

[0033] (2) When the filter element is used in a water treatment device, it is only necessary to remove the protective cover 6, connect the input water pipe to the water inlet 14, and connect the output water pipe to the water outlet 16. Water flows into the filter element through the water inlet 14, and after entering the wading cavity 15, it is filtered by the activated carbon rod 1 and then flows out from the water outlet 16. The filtration work is completed. The structural characteristics of the carbon rod upper cover 4 enable the filter element to play a role in water isolation during the filtration process. There is no need to worry about water that has not been filtered by the filter element being directly output from the water outlet 16.

[0034] (3) The water inlet 14 and the water outlet 16 in the upper shell 2 adopt a novel appearance design. This design scheme can ensure a certain water flow rate and flow rate. The two side protrusions in the lower shell 3 serve as a guide for the installation of the refrigerator filter element. This design is easy to hold the product and facilitates the installation, removal and replacement of the refrigerator filter element.

[0035] (4) The jump key 12 and the spring 13 cooperate with each other. When the male buckle 11 is pressed down, the inverted buckles set at the two ends of the top of the male buckle 11 stretch the two features on the upper end of the female buckle 9 to the left and right. The spring 13 is also compressed as the male buckle 11 is pressed down. The jump key 12 set in the groove on one side of the male buckle 11 slides in the limiting groove slide rail on the inner side of the buckle shell 10 in the direction of the male buckle 11 being pressed down. When it reaches the bottom, the jump key 12 rotates, and its features are stuck at the bottom of the groove slide rail on the inner side of the buckle shell 10. At this time, the buckle assembly is in an open state; when the male buckle 11 is pressed down again, the jump key 12 can be rotated back into the slide rail on the inner side of the buckle shell 10. At this time, the spring 13 generates elastic force to push the male buckle 11 back to its original position. The rebound of the male buckle 11 can also drive the jump key 12 back to its original position. The two features on the upper end of the female buckle 9 are closed. At this time, the buckle assembly is in a clamped state.
