Attached Figure Description

[0015] Figure 1 This is a schematic diagram of a filter element structure provided by this utility model. Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, a filter element structure includes a hollow carbon rod 1, with a cap 2 and an outlet cap 3 having a water outlet hole 4 respectively connected to both ends of the carbon rod 1; a hollow inner filter element 5 with one end closed is disposed inside the carbon rod 1, the inner filter element 5 is connected to the water outlet cap 3, and the interior of the inner filter element 5 is in communication with the water outlet hole 4; the communication between the inner filter element 5 and the water outlet hole 4 serves to filter carbon particles and carbon powder.

[0018] Specifically, in this embodiment, the carbon rod 1 is made of activated carbon granules, which has both filtering and purification effects. One end of the carbon rod 1 is sealed by the cap 2 to prevent water entering the carbon rod 1 from flowing out from that end.

[0019] In this embodiment, the water outlet cap 3 includes a cap body 31. One side of the cap body 31 is provided with a snap-fit ​​portion 32 that covers and snaps onto the end of the carbon rod 1 and a first connecting portion 33 that extends into the carbon rod 1. The side of the cap body 31 opposite to the first connecting portion 33 is provided with a second connecting portion 34.

[0020] The water outlet 4 extends axially through the first connecting part 33 and the second connecting part 34; one end of the inner filter element 5 is coaxially sleeved on the outside of the first connecting part 32 to effectively isolate black water and carbon particles. Furthermore, filter cotton is provided covering the first connecting part 33 and the end of the carbon rod 1 to further improve the filtration effect. Preferably, in this embodiment, the inner filter element 5 is coaxially welded to the water outlet end cap 3.

[0021] Further, the water outlet hole 4 comprises a first hole section 41 located in the first connecting part 33 and a second hole section 42 located in the second connecting part 34; wherein the inner diameter of the first hole section 41 is larger than that of the second hole section 42, so as to quickly discharge the filtered water.
