The water divider also includes a filter screen arranged between the first water outlet channel and the second water outlet channel, and the filtered water flowing out of the second water outlet channel of the filter element enters the first water outlet channel after passing through the filter screen.

[0007] The water separator includes a top cover covering the top of the filter element and a side wall extending downward along the edge of the top cover to cover a portion of the upper end of the filter element. The upper surface of the top cover of the water separator is provided with multiple inclined water guide ribs.

[0008] Wherein, the upper surface of the top cover of the water divider is provided with a plurality of inclined water guide ribs and a plurality of straight water guide ribs at intervals.

[0009] The plurality of inclined water-guiding ribs are inclined downward along the center of the top cover toward the edge thereof.

[0010] Wherein, the multiple inclined water-guiding ribs are evenly distributed on the upper surface of the top cover.

[0011] Among them, the number of inclined water-guiding ribs is at least 4.

[0012] The water divider further includes a protrusion extending upward from the center of the top cover, and an internal channel of the protrusion constitutes the first water outlet channel or a part of the first water outlet channel.

[0013] Wherein, the protrusion has one or more sealing grooves.

[0014] Wherein, the filter element is an activated carbon filter element or a PP cotton activated carbon composite filter element.

[0015] According to an embodiment of the present invention, a water purification device is also provided, which includes the above-mentioned pre-filter device.

[0021] 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.

[0022] 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.

[0023] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] According to an embodiment of the present invention, a pre-filter device is provided, referring to Figure 1 The pre-filter device mainly includes: a filter element 10 and a water separator 20, wherein the filter element 10 can be an activated carbon filter element or a PP cotton activated carbon composite filter element.

[0025] refer to Figure 2 and Figure 3 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, and the side wall 22 covers at least a portion, or a small portion, of the upper end of the filter element 10. A protrusion 23 extending upward is provided in the middle of the water separator 20. The protrusion 23 is hollow. After being filtered by the filter element 10, filtered water 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, wherein the water outlet direction is from bottom to top.

[0026] According to an embodiment of the present application, the water separator 20 includes a filter screen 25, and the specific position of the filter screen 25 is set below the protrusion 23 or the water outlet channel 30. The filter screen 25 is used to filter the filtered water entering the water outlet channel 30, that is, the water filtered by the filter element 10. The filter screen 25 intercepts the carbon particles in the filtered water, so that the filtered water entering the water outlet channel 30 does not contain carbon particles.

[0027] The protrusion 23 also has one or more sealing grooves 24. Figure 2 Two sealing grooves 24 are shown in the figure, and other numbers of sealing grooves can be provided in other embodiments. A sealing ring (not shown) can be provided in the sealing groove 24.

[0028] Continue to refer Figure 2 , the upper surface of the top cover 21 of the water divider has a plurality of inclined water guide ribs 26, which are inclined and descend along the center of the top cover toward the edge of the top cover, and can also extend from the upper surface of the top cover to the side wall. In the embodiment of the present application, the upper surface of the top cover 21 has a plurality of inclined water guide ribs 26 and straight water guide ribs 27 arranged at intervals, and these water guide ribs are evenly distributed on the upper surface of the top cover. Figure 2 In the embodiment shown, 4 inclined water guide ribs and 4 straight water guide ribs are provided, but the present application is not limited thereto, and 6, 8 or 12 water guide ribs may also be provided, which will not be repeated here.

[0029] During water intake, the water flows downward along the outer side of the protrusion 23, passing through the water diversion rib and sidewall 22, and into the filter element. The center of the filter element serves as the outlet channel, through which the filtered water is discharged upward. Upon reaching the water diverter 20, it first passes through the filter screen 25, which intercepts carbon particles in the filtered water, preventing them from entering the outlet channel 30 of the water diverter 20. The carbon-free filtered water then enters the outlet channel 30.

[0030] According to an embodiment of the present invention, a water purification device is also provided, which includes multiple filter elements, such as a pre-filter element, a terminal water inlet filter element and a post-filter element, wherein the pre-filter element device is based on Figures 1 to 3 The filter element device of the described embodiment will not be described in detail.

[0031] Although the present disclosure has been described in detail with reference to specific embodiments of the present application, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the embodiments. Therefore, this application is intended to cover modifications and variations of the present application, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included within the scope of the claims of the present application and their equivalents.

[0032] In addition, the features disclosed in the above description or claims or drawings, in their specific forms or according to the methods or processes for performing the disclosed functions or obtaining the disclosed results, can be used alone or in any combination of these features to implement the present application in their different forms. Specifically, one or more features of any embodiment described in this application can be combined with one or more features of any other embodiment described in this application.
