About the filter module

In Fig. 1 there is only one filter module, which is the first filter module. The first filtration module 1 is an ultrafiltration membrane. The ultrafiltration membrane is composed of hollow fibers in the shape of a "U". The end face of the lower part of the bottle. The bottom of the ultrafiltration membrane of the present utility model is close to the water outlet, and other parts of the ultrafiltration membrane extend toward the water inlet and are limited in the bottle-shaped body. This structure makes the top of the ultrafiltration membrane with relatively loose gaps contact the water source earlier than the bottom with relatively dense gaps. While using the top to intercept larger particles, it ensures that the water source can fully enter the denser bottom, thereby improving Water filtration speed and water filtration effect. Preferably, the tops of the hollow fibers of the present invention are not at the same height. That is, the lengths of the hollow fibers are inconsistent. This design not at the same height can further adjust the density of hollow fibers at different heights, thereby realizing step-by-step filtration and further increasing the filtration speed. Further preferably, the hollow fibers have three lengths, namely the longest long fiber, the shortest short fiber, and the middle fiber whose length is between the long fiber and the short fiber. The root number ratio of long fiber, medium fiber and short fiber is 1:3:6. Each long fiber, three medium fibers, and six long fibers form a group, the long fibers in the same group are located in the middle, the medium fibers surround the long fiber ring cloth, and the short fibers surround the middle fiber ring cloth. Thereby, three tops with different heights are formed in the bottle-shaped body, one of which is a top formed by long fibers, one is a top formed by medium fibers, and one is a top formed by short fibers. The density of the top formed by the long fibers is lower than that of the tops formed by the medium fibers, and the density of the tops formed by the medium fibers is smaller than that of the tops formed by the short fibers. Use three tops with different densities to filter and block water source impurity particles layer by layer.

There are two filter modules in Figure 2. One of them is the first filter module 1. The first filter module 1 is an ultrafiltration membrane. The ultrafiltration membrane is composed of hollow fibers in a "U" shape. The ends of each hollow fiber are hot-pressed together to form an ultrafiltration membrane. The bottom of the filter membrane is located below the sealing plate, and the bottom can be connected to the sealing plate, or there can be a gap between the bottom and the sealing plate. Preferably, there is a gap between the bottom and the sealing plate, so that the unfiltered water can be temporarily stored in the gap, so that the water can pass through the bottom more evenly, so as to ensure the filtration speed. The rest of the ultrafiltration membrane extends downward and is confined within the bottle. The other is the second filter module 2 . The second filter module 2 is placed in the bottle-shaped body, between the first filter module and the first end cap. Further preferably, it is located at the lower port of the bottle-shaped body, so as to allow the replacement of the second filter module 2 . The lower part of the second filter module 2 is preferably provided with outward flanges, and the first end cap uses the flanges to press the second filter module to the lower port of the bottle-shaped body. Therefore, it is only allowed to be fixed by extrusion, which further facilitates the disassembly and replacement of the second filter module. At this time, the inner side wall of the connecting part of the first end cap can be provided with a stepped structure, so as to better suppress the flange while matching with the flange. And further preferably, a sealing ring is provided on the stepped structure. Therefore, water leakage is avoided at the joint between the flange and the first end cover.

There are two filter modules in Figure 3. One of them is the first filter module 1. The first filter module 1 is an ultrafiltration membrane. The ultrafiltration membrane is composed of hollow fibers in a "U" shape. The ends of each hollow fiber are hot-pressed together to form an ultrafiltration membrane. The bottom of the filter membrane is used as the end face of the bottom of the closed bottle. The bottom of the ultrafiltration membrane of the utility model is close to the water outlet, and other parts of the ultrafiltration membrane extend toward the water inlet and are limited in the bottle-shaped body. This structure makes the top of the ultrafiltration membrane with relatively loose gaps contact the water source earlier than the bottom with relatively dense gaps. While using the top to intercept larger particles, it ensures that the water source can fully enter the denser bottom, thereby improving Water filtration speed and water filtration effect. Preferably, the tops of the hollow fibers of the present invention are not at the same height. That is, the lengths of the hollow fibers are inconsistent. This design not at the same height can further adjust the density of hollow fibers at different heights, thereby realizing step-by-step filtration and further increasing the filtration speed. Further preferably, the hollow fibers have three lengths, namely the longest long fiber, the shortest short fiber, and the middle fiber whose length is between the long fiber and the short fiber. The root number ratio of long fiber, medium fiber and short fiber is 1:3:6. Each long fiber, three medium fibers, and six long fibers form a group, the long fibers in the same group are located in the middle, the medium fibers surround the long fiber ring cloth, and the short fibers surround the middle fiber ring cloth. Thereby, three tops with different heights are formed in the bottle-shaped body, one of which is a top formed by long fibers, one is a top formed by medium fibers, and one is a top formed by short fibers. The density of the top formed by the long fibers is lower than that of the tops formed by the medium fibers, and the density of the tops formed by the medium fibers is smaller than that of the tops formed by the short fibers. Use three tops with different densities to filter and block water source impurity particles layer by layer. The other is the second filter module 2 . The second filter module 2 is limited in the first end cover. The second filter module 2 can at least cover the nozzle-like structure. The second filter module is preferably a carbon membrane. When the area of the second filter module is relatively large, as shown in Figure 2, when it is equal to the inner diameter of the second end cover, in order to avoid the pressure damage of the second filter module, the second filter module can be equipped with a supporting grid or an external support frame.

The water source is filtered for the second time through the second filter module 2, thereby improving the filtering effect. A gap is provided between the first filter module 1 and the second filter module 2 to ensure water filtration efficiency.

The second filter module 2 can also be an activated carbon filter module. The utility model selects the type of the filter module, removes large particles and microorganisms in the water source through the ultrafiltration membrane, and further filters impurities through the activated carbon filter module to improve the taste of the water source. Activated carbon filter module, can be activated carbon carbon cloth. When it is carbon cloth, the outer edge of the carbon cloth can be heat-pressed on the upper port of the suction nozzle-shaped structure of the first end cap.
