Description

Technical Field

[0001] This utility model relates to the field of drinking water purification technology, and in particular to a reusable water filter cartridge device. Background Technology

[0002] Existing water filter cartridges often employ a top-opening structure, as shown in publication numbers CN103880205A and CN208115313U. These cartridges consist of an upward-opening housing and a top cover that fits over the opening. With this design, water may enter the housing directly between the housing and the top cover without passing through the inlet filter, resulting in larger particles of impurities in the water not being filtered out. Furthermore, existing inlet filters are typically flat, which hinders the entry of water. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a reusable water filter cartridge device.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: In a first aspect, this application discloses a reusable water filter cartridge device, including a housing and a filter material disposed within the housing. The housing includes a housing body with an opening at the lower end and a lower cover that covers the opening end of the housing body. The top of the housing body is provided with a water inlet, and a concave arc-shaped water inlet filter screen is provided at the water inlet. The bottom of the lower cover is provided with a water outlet, and an water outlet filter screen is provided at the water outlet.

[0005] A further technical solution is that the top edge of the housing body is provided with a radially protruding flange.

[0006] A further technical solution is that the flange end is provided with an upwardly extending flange, and the flange is provided with a filter element handle.

[0007] A further technical solution is that the flange is provided with several through holes.

[0008] A further technical solution is that the housing body, lower cover, inlet filter, outlet filter, and filter element handle are all made of SUS304 stainless steel.

[0009] A further technical solution is that the housing body is threadedly connected to the lower cover.

[0010] A further technical solution is to provide a sealing ring between the housing body and the lower cover.

[0011] Secondly, this application also discloses a water filter pitcher, including the aforementioned filter cartridge device.

[0012] The beneficial effects of adopting the above technical solution are as follows: This invention features a bottom-opening structure, forcing water to enter from the top inlet. After being dispersed by the concave arc-shaped inlet filter screen, the water passes through the filter material, physically blocking bypass channels. Simultaneously, the arc-shaped structure guides the water flow to diffuse in all directions, facilitating the entry of water. The threaded lower cover forms a mechanical seal with the housing body, and together with a silicone sealing ring, achieves a double sealing barrier. Attached Figure Description

[0013] Figure 1 This is a three-dimensional structural diagram of the filter element device of this utility model; Figure 2 This is a cross-sectional view of the filter element device of this utility model; Figure 3 This is a three-dimensional structural diagram of the water filter pitcher of this utility model.

[0014] In the diagram: 1. Filter material; 2. Housing body; 201. Inlet; 202. Flange; 203. Flanged edge; 204. Through hole; 3. Bottom cover; 301. Outlet; 4. Inlet filter screen; 5. Outlet filter screen; 6. Filter cartridge handle. Detailed Implementation

[0015] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0016] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] like Figure 1 and Figure 2As shown, a reusable water filter cartridge device is disclosed, including a housing and filter material 1 disposed within the housing. The housing includes a housing body 2 with an open lower end and a lower cover 3 threadedly connected to the open end of the housing body 2. A sealing ring is provided between the housing body 2 and the lower cover 3. The top of the housing body 2 has a water inlet 201, and a concave arc-shaped water inlet filter 4 is provided at the water inlet 201. The water inlet filter 4 extends into the cavity of the housing body 2, guiding the water flow to diffuse in all directions, making it easier for the water to enter. The bottom of the lower cover 3 has a water outlet 301, and an outlet filter 5 is provided at the water outlet 301.

[0018] The design features a bottom-opening structure, forcing water in through the top inlet 201. After being dispersed by the concave arc-shaped inlet filter 4, the water passes through the filter material 1, physically blocking bypass channels. Simultaneously, the arc-shaped structure guides the water flow to diffuse in all directions, facilitating the entry of water. The threaded lower cover forms a mechanical seal with the housing body, working in conjunction with a silicone sealing ring to achieve a double sealing barrier.

[0019] The top edge of the housing body 2 is provided with a radially protruding flange 202, which fixes the filter element in the water filter pitcher. For easy handling, the end of the flange 202 is provided with an upwardly extending flange 203, and the flange 203 is provided with a filter element handle 6.

[0020] The flange 203 has several through holes 204 for allowing the water to be filtered to flow smoothly into the inlet filter screen 4 of the filter element device.

[0021] The housing body 2, lower cover 3, inlet filter screen 4, outlet filter screen 5, and filter element handle 6 are all made of SUS304 stainless steel.

[0022] like Figure 3 As shown, this application also discloses a water filter pitcher, including the above-described filter cartridge device.

[0023] When using this filter cartridge, rotate the lower cover 3 counterclockwise to expose the lower opening of the housing body 2. Insert the filter material 1 into the housing cavity. Tighten the lower cover 3 clockwise to ensure the threads are fully engaged. Hold the filter cartridge by the handle 6 and place it in the designated position on the water filter pitcher. It is then ready for normal use. To replace the filter material 1, remove the filter cartridge, unscrew the lower cover 3, pour out the filter material 1, clean it, and then reinstall the new filter material 1.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
