Description

Technical Field

[0001] The utility model relates to the technical field of kettle filter devices, in particular to a carbon fiber kettle filter. Background Art

[0002] The main function of a kettle filter is to filter out impurities such as sediment, particulate matter, and heavy metals in water, remove water scale, improve water quality and taste, reduce water alkali and water scale, and adsorb harmful substances such as residual chlorine, chloramine, and pesticides in water.

[0003] At present, most kettle filters adopt a mixture of resin particles and activated carbon particles. As the filter is under the action of gravity and the impact of water flow for a long time, the mixed particle filter material of activated carbon and resin becomes agglomerated, resulting in a situation where the water flow through the filter is too small or no water comes out.

[0004] Therefore, a carbon fiber kettle filter is designed to solve the above problems. Summary of the Utility Model

[0005] According to the above existing technical problems, the utility model provides a carbon fiber kettle filter, which adopts a non-woven fabric, activated carbon fiber, and resin fiber layer to form an inner core filter layer, not only greatly enhancing the filtering effect, but also having a relatively stable water flow rate after filtration, preventing the problem of reduced flow rate caused by the agglomeration of loose particulate filter materials due to long-term use.

[0006] To achieve the above purpose, the technical method of the utility model is as follows:

[0007] A carbon fiber kettle filter, characterized in that it comprises an end cap, a bottom cap, and an inner core. One end of the inner core is inserted into the end cap slot provided on the end cap and is adhesively connected to the bottom of the end cap slot with hot melt adhesive. The other end of the inner core is inserted into the bottom cap slot provided on the bottom cap and is adhesively connected to the bottom of the bottom cap slot with hot melt adhesive. The inner core consists of a skeleton and an inner core filter layer. An inner core filter layer is provided on the outer side of the skeleton. The inner core filter layer from the inside to the outside is successively an inner layer non-woven fabric, activated carbon fiber, resin fiber, and an outer layer non-woven fabric.

[0008] A sealing ring is installed in the groove provided on the end cap for sealing during the installation of the filter to prevent internal leakage.

[0009] Specifically, the upper end port of the inner side ring of the bottom cap slot on the bottom cap is provided with a conical structure to facilitate the insertion operation of the inner core.

[0010] Specifically, a central hole is provided at the central position of the end cap, and this central hole is used for the outflow of the filtered water.

[0011] Advantages of the Utility Model

[0012] The inner core filter layer designed in this utility model is divided into four layers for filtration. The first layer is the outer non-woven fabric, which intercepts solid particles in water. The second layer is resin fiber used to exchange calcium and magnesium ions in water to reduce the water hardness. The third layer is activated carbon fiber, which is used to adsorb residual chlorine, tastes and odors, and solid particles in water. The fourth layer is the inner non-woven fabric, which further intercepts solid particles in water and the lint of resin and carbon fiber. This not only greatly enhances the filtration effect, but also makes the flow rate of the filtered water relatively stable, preventing the problem of reduced flow rate caused by the accumulation and caking of loose granular filter materials after long-term use.

[0013] The inner core designed in this utility model is provided with an installation sealing ring on its end cover for sealing when the filter element is installed into the kettle or the water bucket of the kettle. And the inner core is inserted into the slots provided on both end covers, and the inner core and the bottom of the slot are adhesively connected by hot melt adhesive, which not only makes the connection between the inner core and the end cover and the bottom cover firm, but also realizes the sealing at the connection between the inner core and the end cover and the bottom cover, preventing the mixing of pre-filtered water and post-filtered water.

[0024] Embodiment 1

[0025] As shown in the figure, as Figure 4 One end of the inner core 1 is inserted into the end cap slot 21 provided on the end cap 2 and is adhesively connected to the bottom of the end cap slot 21 with hot melt adhesive. The other end of the inner core 1 is inserted into the bottom cap slot 31 provided on the bottom cap 3 and is adhesively connected to the bottom of the bottom cap slot 31 with hot melt adhesive. The adhesive connection with hot melt adhesive not only makes the connection between the inner core 1 and the end cap 2 and the bottom cap 3 stable but also realizes the sealing at the connection between the inner core 1 and the end cap 2 and the bottom cap 3, preventing the pre-filter water 101 and the filtered water from mixing. And a central hole 22 is provided at the central position of the end cap 2, and this central hole 22 is used for the outflow of the filtered water. As Figure 5 , the upper end port of the inner ring 311 of the bottom cap slot 31 on the bottom cap 3 is provided with a conical structure, which is convenient for the operation of inserting the inner core 1 onto the bottom cap 3.

[0026] The inner core 1 is composed of a framework 11 and an inner core filter layer. The inner core filter layer is disposed outside the framework 11. The inner core filter layer successively includes an inner non-woven fabric 121, activated carbon fibers 122, resin fibers 123, and an outer non-woven fabric 124 from the inside to the outside. Among them, the first layer is the outer non-woven fabric 124, which intercepts solid particulate matters in water. The second layer is the resin fibers 123, which are used to exchange calcium and magnesium ions in water to reduce the hardness of water. The third layer is the activated carbon fibers 122, which are used to adsorb residual chlorine, tastes, odors, and solid particulate matters in water. The fourth layer is the inner non-woven fabric 121, which further intercepts solid particulate matters in water and the lint of resin and carbon fibers. This not only greatly enhances the filtering effect, but also the flow rate of the filtered water is relatively stable, preventing the problem of reduced flow rate caused by the accumulation and caking of bulk granular filter materials during long-term use.

[0027] A sealing ring 4 is installed in the groove provided on the end cap 3 for sealing during the installation of the filter element designed by the present utility model. Figure 6 That is, the sealing ring 4 is located between the connection positions of the end cap and the water outlet on the kettle, preventing internal leakage problems during the filtering process.

[0028] During use, the present utility model is installed in a kettle. For example, Figure 6 as shown, the pre-filter water 101 is filtered layer by layer through the inner core process layer, and the filtered water finally flows out from the central hole 22 on the end cap 2.
