Technical Field

[0001] This application relates to the field of filter technology, and in particular to a kettle filter with removable and replaceable filter media. Background Technology

[0002] A water filter pitcher is a household drinking water filtration device used by families who cannot afford to install one or who are only staying in the house for a short period of time to purify their drinking water. It uses a built-in filter to remove limescale, heavy metals, particulate impurities, plankton, and odors from the water, improving water quality and taste.

[0003] However, most existing removable and replaceable filter media in kettle filter cartridges use filter resin as the filling material. Because filter resin consists of small particles, leakage is common, affecting water filtration efficiency. To address this, the applicant adopted the technical solution described in utility model patent application number "202421799744.X" (hereinafter referred to as the prior art) to solve the aforementioned technical problem. However, in actual production, the prior art uses ultrasonic welding to weld the outlet shell and connecting shell together, making it impossible to disassemble and replace the filter media. This makes it difficult to meet users' needs for regular filter media replacement, limiting product maintainability and lifespan. Therefore, there is an urgent need to develop a new type of removable and replaceable filter media kettle filter cartridge to meet practical application needs. Utility Model Content

[0004] The main objective of this application is to provide a water bottle filter cartridge with removable and replaceable filter media, aiming to solve the aforementioned technical problems.

The removable and replaceable filter media water bottle filter element also includes a third sealing ring disposed inside the connecting water inlet groove for sealing the connection.

[0012] As described above, the removable and replaceable filter media water bottle filter cartridge has multiple upward protrusions on the upper side of the intermediate connecting plate, which are spaced apart to limit the connection of the third sealing ring.

[0013] Compared with the prior art, the above application has the following advantages: In this application, when the outlet housing and the connecting housing are assembled, the second sealing ring is pressed between them to achieve a seal, while the first sealing ring ensures the seal between the support plate and the outlet housing, preventing unfiltered water from passing through. This ensures that all water flows must be filtered by the filter rod assembly before entering the central cavity, then flowing through the water passage into the outlet chamber, and finally flowing out from the outlet hole. This ensures that every drop of water is effectively filtered, improving the safety and purity of drinking water. When the filter rod assembly needs to be replaced, only the outlet housing needs to be disassembled to remove the support plate and the internal filter rod assembly, making replacement or cleaning convenient. The operation is simple and does not require replacing the entire filter element, reducing usage costs, improving resource utilization, realizing a sustainable, low-carbon, and environmentally friendly production concept, and further enhancing the practicality and environmental value of the kettle filter element.

[0029] In one embodiment of this application, as Figures 1 to 11 As shown, a water bottle filter cartridge with removable and replaceable filter media includes a connecting housing 1, a filter rod assembly 2, a support plate 3, a water outlet housing 4, a first sealing ring 5, and a second sealing ring 6. Specifically, the upper side of the connecting housing 1 is provided with a connecting water inlet groove 101, and the lower side is provided with a water filtration chamber 102, and an intermediate connecting plate 103 is provided between the water inlet groove 101 and the water filtration chamber 102. The intermediate connecting plate 103 is provided with a communicating water inlet hole 1031. The filter rod assembly 2 is disposed in the water filtration chamber 102, and a central cavity 201 is provided in the middle of it; The support plate 3 is located on the lower side of the filter rod assembly 2, and a water passage hole 301 communicating with the central cavity 201 is provided on it; The water outlet housing 4 is detachably connected to the lower side of the connecting housing 1, and its upper edge extends into the interior of the accommodating filter chamber 102 to support the support plate 3. The water outlet housing 4 has an outlet chamber 401 inside and an outlet hole 402 connected to the outlet chamber 401 on its lower side. The first sealing ring 5 is disposed between the water outlet shell 4 and the support plate 3; The second sealing ring 6 is disposed between the connecting housing 1 and the water outlet housing 4.

[0030] In this application, when the water outlet housing 4 and the connecting housing 1 are assembled, the second sealing ring 6 is pressed between them to achieve a seal, while the first sealing ring 5 ensures the seal between the support plate 3 and the water outlet housing 4, preventing water that has not been filtered by the filter rod assembly 2 from passing through. This ensures that all water flows must be filtered by the filter rod assembly 2 before entering the central cavity 201, then flowing through the water passage 301 into the water outlet cavity 401, and finally flowing out from the water outlet hole 402. This ensures that every drop of water is effectively filtered, improving the safety and purity of drinking water. When the filter rod assembly 2 needs to be replaced, only the water outlet housing 4 needs to be disassembled to remove the support plate 3 and the internal filter rod assembly 2, making it easy to replace or clean. The operation is simple and does not require replacing the entire filter element, reducing usage costs, improving resource utilization, realizing a sustainable, low-carbon, and environmentally friendly production concept, and further enhancing the practicality and environmental value of the kettle filter element.

[0031] Furthermore, the lower periphery of the support plate 3 is provided with an upper concave annular groove 303; the first sealing ring 5 is disposed inside the upper concave annular groove 303 and located on the upper side of the water outlet housing 4. When the water outlet housing 4 is assembled with the connecting housing 1, the upper edge of the water outlet housing 4 pushes against the support plate 3, so that the first sealing ring 5 is tightly attached to the inner wall of the upper concave annular groove 303 to form a seal, effectively preventing unfiltered water from flowing out.

[0032] Furthermore, the lower inner wall of the water-filtering chamber 102 is provided with a plurality of spaced hook portions 1021; The upper circumference of the water outlet housing 4 is provided with a plurality of snap-fit ​​holes 403 corresponding to the snap-fit ​​portion 1021, and a second connecting ring groove 404 located below the snap-fit ​​holes 403 for connecting the second sealing ring 6.

[0033] When the water outlet housing 4 is screwed into the connecting housing 1, the snap-fit ​​hole 403 and the snap hook part 1021 are engaged and connected, so that a firm and detachable connection is formed between the water outlet housing 4 and the connecting housing 1. At the same time, the second sealing ring 6 is embedded in the second connecting ring groove 404 and is pressed and undergoes elastic deformation, thereby filling the gap between the connecting housing 1 and the water outlet housing 4, achieving a tight seal at the connection between the two and effectively preventing water leakage.

[0034] Furthermore, the lower side of the intermediate connecting plate 103 is provided with a downwardly protruding positioning connecting part 1032; The filter rod assembly 2 includes a filter rod 20 and a filter rod cover 21 disposed on the upper side of the filter rod 20; The filter rod 20 has a central cavity 201 in its middle section. The filter rod 20 is a carbon filter rod, which has the advantages of excellent adsorption performance, large dirt-holding capacity, long service life, non-toxicity, odorlessness, and no secondary pollution, and can effectively overcome the defect of easy leakage of water filter resin. In addition, it can effectively remove organic matter, particles, rust, residual chlorine, odors, etc. from water.

[0035] The filter rod cover 21 has a first connecting ring groove 211 on its lower side that connects to the filter rod 20, and also has a downward extension 212 that extends downward into the middle cavity 201.

The support plate 3 is also provided with a recessed connecting annular groove 302 located outside the water passage hole 301 for connecting with the lower side of the filter rod 20. Its purpose is to connect the filter rod 20 and allow water to flow sequentially through the water inlet groove 101, the connecting water inlet hole 1031, the filtration chamber 102, the filter rod 20, the central cavity 201, and the water passage hole 301, thereby completing the water filtration function.

[0036] Furthermore, the number of filter rod assemblies 2 is multiple, and the number of positioning connecting parts 1032, water passage holes 301, and recessed connecting ring grooves 302 are all equal to the number of filter rod assemblies 2. The purpose is to further improve water filtration efficiency by setting multiple sets of filter rods 20.

[0037] Furthermore, the inner sidewall of the connecting water inlet groove 101 is provided with connecting threads 1011 for threaded connection; the water bottle filter element with removable and replaceable filter media also includes a third sealing ring 7 disposed inside the connecting water inlet groove 101 for sealing connection. The purpose is to achieve a sealed connection.

[0038] Furthermore, the upper side of the intermediate connecting plate 103 is provided with a plurality of upwardly protruding and spaced-apart limiting connecting protrusions 1033 for limiting the connection of the third sealing ring 7, the purpose of which is to prevent the third sealing ring 7 from shifting and to form an effective limiting effect.

[0039] Furthermore, the removable and replaceable filter media water bottle filter element also includes a secondary filter bag (not shown in the figure) disposed in the water outlet chamber 401.
