[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0023] Although the present invention may include various embodiments in different forms, for some preferred embodiments described in detail in the specification and shown in the drawings, it should be understood that the contents disclosed in the present invention should be regarded as schematic illustrations of the principles of the present invention, and these shown embodiments are not intended to limit the scope of protection of the present invention.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] According to the embodiment of the present invention, a filter element device is proposed, referring to Figure 1 The filter element device mainly includes: a filter element 10 and a water separator 20 basically arranged above the filter element. A water-proof cloth can be provided between the water separator 20 and the filter element 10 to ensure that water does not leak.

[0026] In the embodiment of the present application, the filter element 10 can be a pre-filter element or a terminal water inlet filter element of the water purifier. The pre-filter element can be an activated carbon filter element or a PP cotton activated carbon composite filter element. The pre-filter element can filter out large particles such as mud, rust, insect eggs, and red worms in the tap water; the terminal water inlet filter element can be a reverse osmosis filter element, a nanofiltration filter element, or an ultrafiltration filter element. The terminal water inlet filter element can be used to remove chlorine, heavy metals, bacteria, viruses, algae, and suspended solids in the water.

[0027] refer to Figures 2 to 4 The water separator 20 includes a top cover 21 and a side wall 22. The top cover 21 is circular and covers the top of the filter element 10. The annular side wall 22 extends downward from the edge of the top cover 21, covering at least a portion, or a small portion, of the upper end of the filter element 10. A protrusion 23 extending upward is located in the middle of the top cover 21 of the water separator 20. The protrusion 23 is hollow. Filtered water from the filter element 10 flows upward and out through the channel within the protrusion 23. Therefore, the channel within the protrusion 23 constitutes the filtered water outlet channel 30, or a portion of the filtered water outlet channel 30, with water outlet direction from bottom to top.

[0028] In the embodiment of the present application, a plurality of inclined water guide ribs 26 are provided on the upper surface of the top cover 21 of the water distributor 20. These water guide ribs 26 are inclined downward along the center position of the top cover 21 toward the edge of the top cover. These inclined water guide ribs are evenly distributed on the upper surface of the top cover. Figure 2 and Figure 3 In the embodiment shown, eight inclined water guide ribs are provided. However, in some other embodiments of the present application, inclined water guide ribs and straight water guide ribs may be provided at intervals on the upper surface of the top cover 21. For example, four inclined water guide ribs and four straight water guide ribs may be provided at intervals. Figure 2 and Figure 38 inclined water guide ribs are shown, but the present application is not limited thereto. 4, 6 or 12 water guide ribs may also be provided, which will not be described in detail.

[0029] In this application, the outside of the water divider 20 and the outside of the filter element are the water inlet side. Specifically, the incoming water flows downward along the outside of the protrusion 23, passes through the upper surface of the top cover 21 and the outside of the sidewall 22, and then enters the filter element along the outside of the filter element 10. After water enters the water inlet side, the water guide ribs on the upper surface of the top cover 21 guide and pressurize the water, which can be evenly and smoothly introduced into the water inlet side of the filter element, ensuring full contact between the filter assembly and the water, thereby improving the service life and filtration effect of the filter element. The water guide ribs can also increase the linear velocity of the water flow, so that the water flows in a fixed direction without turbulence.

[0030] refer to Figure 2 and Figure 5 The filtered water filtered by the filter element 10 flows out from the water outlet channel 30 in the middle of the filter element from bottom to top. The filtered water outlet channel 30 passes through the protrusion from the middle, and the annular channel outside the filtered water outlet channel 30 is the wastewater channel 35.

[0031] According to an embodiment of the present invention, a water purification device is also provided, which includes the filter element device as described above. The filter element device can be a pre-filter element or a terminal water inlet filter element.

[0032] According to the above technical solution of the present application, by arranging inclined water guide ribs on the upper surface of the top cover of the water divider, a diversion and pressurized water inlet channel is formed on the upper surface of the top cover, which not only enables the water to flow in a fixed direction without turbulence, but also increases the water flow speed so that the water to be filtered contacts the filter assembly more fully, thereby obtaining a better filtering effect and effectively extending the service life of the filter element.
