Description

[Technical Field]

[0001] The present invention relates to the technical field of water purification devices, and more particularly to a faucet filter cartridge for use in a faucet. [Background technology]

[0002] Faucet filter cartridges are water purification devices that are attached to the inside of water faucets to remove impurities and harmful substances from water, providing cleaner and safer drinking water.

[0003] This type of faucet filter cartridge has the following functions: (1) Water purification: Removes residual chlorine, mud, rust, heavy metals, odors, bacteria, etc., improving water quality. (2) It can adjust the acidity-alkalinity balance. (3) Replenishing mineral components: The filter media removes residual chlorine and heavy metals from the water, making it easier to drink, and also provides water containing minerals and trace elements, helping to maintain nutritional balance. Summary of the Invention [Problem to be solved by the invention]

[0004] However, most conventional faucet filter cartridges have a one-piece structure with the filter media fixed concentrically, which results in insufficient filtration performance and a limited selection of filter media types, making it difficult to meet the individual needs of users. [Means for solving the problem]

[0005] In order to solve the above problems, the present invention provides a filter cartridge for a faucet, comprising a first filtration section, a second filtration section, and a third filtration section; the first filtration section has a cylindrical filter body, the peripheral side walls of which function as a water-permeable surface, a closed rear end, and a through hole formed in the center, which is configured to direct water toward the front end; the second filtration section is a storage chamber fixed to the front end of the filter body, the rear end of which communicates with the through hole, a water-permeable gap formed at the front end, and granular filter media disposed inside; and the third filtration section is a chamber connected to the front end of the storage chamber, the front end of which has a water outlet formed, and the filter media stored inside.

[0006] In addition, the faucet filter cartridge of the present invention is characterized in that the filter body is made of formed activated carbon.

[0007] The faucet filter cartridge of the present invention is characterized in that the granular filter material is one or more of Maifan stone, a scale inhibitor, and a hydrogen generating agent.

[0008] In addition, the faucet filter cartridge of the present invention is characterized in that the filter material is a hollow fiber membrane.

[0009] In addition, the faucet filter cartridge of the present invention is characterized in that an O-ring is provided on the outer periphery of the spout.

[0010] The faucet filter cartridge of the present invention is characterized in that a water discharge plate is provided inside the water discharge port, and a plurality of water discharge holes are formed in the water discharge plate.

[0011] The faucet filter cartridge of the present invention is characterized in that the rear end surface of the accommodating chamber seals the front end surface of the filter body.

[0012] The faucet filter cartridge of the present invention is also characterized in that the rear end of the chamber is sealed and connected to the outer peripheral side wall of the storage chamber.

[0013] The faucet filter cartridge of the present invention is also characterized in that a cap portion is provided at the rear end of the filter body, and the rear end of the filter body is sealed by the cap portion. [Effects of the Invention]

[0014] According to this invention, by arranging multiple filter media (e.g., granular filter media 22, filter media 32) in multiple stages in the axial direction, the filtration distance is longer than that of conventional faucet filter cartridges, allowing water to be filtered more thoroughly and improving water purification performance.

[0015] In addition, by combining different filter media, it is possible to obtain water purification effects that meet the individual needs of each user. [Brief explanation of the drawings]

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0018] First Embodiment As shown in FIGS. 1 and 2, the faucet filter cartridge according to the present invention comprises a first filtration section 1, a second filtration section 2 and a third filtration section 3.

[0019] The first filtration section 1 includes a cylindrical filter body 11, which is made of, for example, formed activated carbon, and whose peripheral sidewall functions as a water-permeable surface. Note that the filter body 11 is not limited to formed activated carbon, and may be made of other filter materials such as polypropylene fiber. The rear end of the filter body 11 is sealed with a cap 13, which is fixed to the filter body 11 with an adhesive. A through-hole 12 is formed in the center of the filter body 11, and water permeates into the filter body 11 from the water-permeable surface and flows out the front end through the through-hole 12.

[0020] The second filtration section 2 includes a storage chamber 21 fixed to the front end of the filter body 11, and the rear end face of the storage chamber 21 seals the front end face of the filter body 11 and is fixed with an adhesive. A connecting hole communicating with the through hole 12 is formed at the rear end of the storage chamber 21, and a water-passing gap is provided at the front end. Granular filter material 22 is disposed inside the storage chamber 21, and the granular filter material 22 is composed of one or more of bakuhan stone, a scale inhibitor, and a hydrogen generator. Bakuhan stone improves the mouthfeel, the scale inhibitor suppresses the formation of limescale, and the hydrogen generator has the effect of generating hydrogen water.

[0021] The third filtration section 3 includes a chamber 31, the rear end of which is hermetically connected to the outer peripheral side wall of the storage chamber 21, so that the entire storage chamber 21 is housed within the chamber 31. A water outlet 33 is formed at the front end of the chamber 31, and a filter medium 32 is disposed inside the chamber 31. The filter medium 32 is preferably made of a hollow fiber membrane.

[0022] In addition, an O-ring is provided on the outer periphery of the water outlet 33 to improve airtightness and water leakage prevention performance when installed.

[0023] <Second embodiment> 3 and 4, Example 2 has a configuration similar to Example 1, but differs in that a water discharge plate 34 is provided inside the water discharge port 33, and a plurality of water discharge holes are formed in the water discharge plate 34. This configuration allows water to come into uniform contact with the granular filter medium 22, further improving filtration efficiency.

[0024] The embodiments of the present invention are merely examples, and a person skilled in the art may make various changes, modifications, or substitutions based on the technical ideas described, and all of these are considered to be included in the technical scope of the present invention.
