BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic structural diagram of the present invention;

[0017] FIG2 is another structural schematic diagram of the present utility model;

[0018] FIG3 is another structural schematic diagram of the present utility model;

[0019] FIG4 is another structural schematic diagram of the present invention; DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0021] Referring to Figures 1, 2, 3, and 4, a mineral slow-release filter element comprises a filter housing 1 with a water inlet 2 and a water outlet 3. The filter housing 1 is tubular and contains a tubular activated carbon rod 4 for filtering water. The top of the carbon rod 4 abuts the top of the filter housing 1, while the bottom of the carbon rod 4 abuts the bottom of the filter housing 1, thereby dividing the space within the filter housing 1 into a first space within the carbon rod 4 and a second space outside the carbon rod 4. One of the water inlet 2 and the water outlet 3 is located in the first space, and the other is located in the second space.

[0022] One of the first space and the second space is filled with a mineral. The mineral may be one of strontium, calcium or selenium. Minerals are essential trace elements for the human body and solve the problem of mineral deficiency in some water sources.

[0023] Specific embodiment 1

[0024] Referring to Figure 1 , the water inlet 2 is located on the top of the filter housing 1, facing the hollow cavity of the carbon rods. The water outlet 3 is located on the side wall of the filter housing. This embodiment allows the filter housing to directly cover the carbon rods, leaving no gap between the filter housing and the carbon rods.

[0025] The minerals are filled in the carbon rods. Thus, the carbon rods 4 are used to accommodate the minerals, eliminating the need for a separate accommodating structure. This also allows the minerals to be replaced at the same time as the carbon rods during use.

[0026] The carbon rod's nozzle is capped with a water outlet. This cap limits the rate of water release from the rod, allowing for a slow release of minerals. A removable aluminum foil membrane is also located outside the cap, sealing the outlet on the end cap to prevent minerals from escaping before use.

[0027] A filter screen 5 is installed at the water inlet. It performs a coarse filtration of water entering the filter housing, removing larger particles. A carbon rod can be used to press the filter screen 5 against the filter housing. This makes installation of the filter screen more convenient, eliminating the need for a fixed structure on the filter housing. It also allows for filter replacement.

[0028] The filter cartridge housing comprises sidewalls, a top, and a bottom. The sidewalls and bottom / top can be threadedly connected. Unscrewing the threads allows the bottom and sidewalls to separate, facilitating the insertion of the carbon rod. Preferably, the top and sidewalls are threadedly connected, facilitating both insertion of the carbon rod and the clamping of the filter screen. A recessed portion can be provided on the lower end surface of the top, housing the filter screen. The outer diameter of the recessed portion should be no less than the outer diameter of the carbon rod. This prevents the carbon rod from shaking.

[0029] Specific embodiment 2

[0030] 2 , the water inlet 2 is opened on the top of the filter housing, facing the hollow cavity of the carbon rod 4 ; the water outlet 3 is opened on the bottom of the filter housing 1 , and located outside the carbon rod 4 .

[0031] In this embodiment, the minerals are preferably filled in the gap between the carbon rod and the filter housing, thereby ensuring the amount of added minerals and ensuring that the minerals can be completely used up.

[0032] Preferably, the filter element housing includes side walls, a top 6, and a bottom. The top 6 includes an annular base plate. A downward flange is provided at the outer edge of the base plate. The inner edge of the base plate is threadedly connected to the carbon rod. The top of the carbon rod extends from the water inlet. The bottom of the carbon rod is sealed and connected to the bottom of the filter element housing, and the side wall rests on the inner side of the flange.

[0033] The top of the carbon rod can be provided with a tearable aluminum foil film, so that the top pipe opening of the carbon rod is sealed with the aluminum foil film to prevent impurities from entering the carbon rod before the carbon rod is used.

[0034] Specific embodiment 3

[0035] 3 , the water inlet 2 is opened on the top of the filter housing, and the water inlet 2 is located outside the carbon rod; the water outlet 3 is opened on the bottom of the filter housing, and the water outlet 3 is facing the hollow cavity of the carbon rod.

[0036] In this embodiment, the minerals are preferably filled in the carbon rod. Thus, the carbon rod 4 is used to accommodate the minerals, and there is no need to set up a separate accommodating structure. It is also allowed to replace the minerals at the same time as the carbon rod is replaced during use. Yes, the carbon rod is provided with an end cap at the pipe mouth, and a water outlet is opened on the end cap. Thus, the end cap is used to limit the water outlet speed of the carbon rod, thereby playing a role in slow release of minerals. Yes, the carbon rod is also provided with a removable aluminum foil film at the pipe mouth, and the aluminum foil film is located on the outside of the end cap. Thus, the aluminum foil film is used to seal the water outlet on the end cap, thereby preventing the minerals from escaping from the carbon rod before the carbon rod is used.

[0037] Specific embodiment 4

[0038] Referring to Figure 4 , the water inlet 2 is located on the side wall of the filter housing; the water outlet 3 is located on the bottom of the filter housing, facing the hollow cavity of the carbon rod. In this embodiment, the mineral is preferably filled within the carbon rod. This allows the carbon rod 4 to hold the mineral, eliminating the need for a separate storage structure. This also allows the mineral to be replaced simultaneously with the carbon rod during use.

[0039] The outside of the filter element housing can be covered with a filter screen, so that the filter screen can be used to coarsely filter the water entering the filter element housing to remove larger particles.
