Referring to fig. 1 to 3, a filter element assembly 100 according to an embodiment of the first aspect of the present invention is shown. The filter element assembly 100 of the present invention is used for filtering water. It will be appreciated that the cartridge assembly 100 may also be used to filter other fluids, and even gases. In some embodiments, the filter cartridge assembly 100 includes an elongate body 200, the elongate body 200 having a containment cavity 201, the containment cavity 201 filled with filter material 226. One end of the elongated body 200 is provided with a water outlet 205, the other end of the elongated body 200 is provided with an opening 204, and the water outlet 205 and the opening 204 are both communicated with the accommodating cavity 201. Raw water enters from the opening 204, is filtered into purified water by the filter element assembly 100 and then is discharged from the water outlet 205. The filter cartridge assembly 100 includes a cover 206, the cover 206 being disposed at the opening 204, the cover 206 including a base 229 and a projection, the projection being disposed to project upwardly from the base 229, the projection being disposed with a through-hole 231. A protrusion is provided in the middle of the cover 206, the protrusion comprising a protruding face 230 parallel to the base 229. And the through-hole 231 penetrates the protruding surface 230. The cap 206 may prevent the filter material 226 from overflowing and provide preliminary filtering before raw water enters the filter material 226. During the filtration process, the raw water permeating from the base 229 has a gravity F1, and the cover 206 applies a surface tension F2 opposite to the gravity F1 to the raw water at the base 229. If F1 is greater than F2, the raw water is able to permeate through the base 229 to be subsequently filtered by the filter media 226. However, there are times when F1 and F2 are in equilibrium with each other, and the raw water cannot smoothly enter the filter material 226 from the base 229. Since the through hole 231 is formed on the protruding portion, when F1 and F2 are balanced, raw water directly enters the filter material 226 from the through hole 231, and the balance between F1 and F2 at the base 229 is broken, so that raw water can smoothly enter the filter material 226. In addition, since the through holes 231 are formed, air bubbles or air pockets formed in the filter material 226 during the filtering process may be discharged through the through holes 231, thereby preventing the air bubbles or air pockets from preventing the raw water from entering the filter material 226. In some embodiments, filter media 226 may be provided like a water table retention in U.S. patent US10099942B 2. In patent US10099942B2, the filter material 226 is provided in order from top to bottom as a micron filter layer, a mixed bed ion exchange layer, a separator layer, a redox aluminum alloy layer, and a carbon screen layer. In some embodiments, filter media 226 may be arranged in layers or in a mixture. In some embodiments, the carbon filter media layer is the last layer of filter material 226 that filtered water passes through before exiting the elongated body 200, and in some examples, the carbon filter media layer is the first layer of filtered water as it enters the filter material 226.

The cover 206 is stepped as a whole by providing a projecting surface 230 parallel to the base 229. The height difference between the protruding surface 230 and the base 229 is fixed, so that the height difference can be set more precisely to ensure that the balance between F1 and F2 is broken when raw water enters the filter material 226 from the through hole 231.

Referring to fig. 2, 3, and 6, in some embodiments, the cap 206 includes a first peripheral portion 207 located at the periphery of the cap 206.

In some embodiments, the first connecting rods 209 extend radially or in other suitable directions. The concentric connection 210 forms the outer periphery of the projection 208. The protruding structure 208 may be any upwardly extending structure, for example, in fig. 1 and 6, the protruding structure 208 is dome-shaped. The connecting portion 210 is substantially coplanar with the base portion 229. The raised structure 208 is also concentric with the first peripheral portion 207. The protruding structure 208 extends/protrudes vertically above the base 229 and forms a protruding face 230. The second link 211 extends radially from the projecting structure 208 and is substantially coplanar with the projecting face 230. A second connecting rod 211 connects the lug structure 208 to a support ring 212. The support ring 212 provides a through hole 231. In some embodiments, second connecting bar 211 does not extend radially, but rather extends in other suitable directions. The first connecting rod 209 supports a base 229 formed by the first peripheral portion 207 and the connecting portion 210.
