According to the study, a normal person can live for about 30 days without water and food. However, in the absence of water and food, it can only live for seven days. It is true that water is a human body. The essential element that is indispensable.

In the early days, most of the drinking water sources were well water, rivers or groundwater, and now the drinking water source is the tap water source that is stored in the reservoir and then treated. However, with the development of heavy industry and the abuse of pesticides, the content of harmful heavy metals in water sources has often reached the level of harmful human health. In addition, the water and soil conservation in the water source area is not effective. After the typhoon, the turbidity of the raw water in the reservoir suddenly rises, causing a serious burden on the water purification field, even reaching the point where it cannot be disposed of. Even if the raw water is treated in advance by the purified water and then supplied to the people through the tap water pipeline, if the water after the clean water treatment is not subjected to secondary treatment such as filtration, it is only through the boiling procedure that the impurities in the tap water cannot be completely removed. Harmful substances may affect human health.

In order to facilitate the user to re-treat the tap water source from the pipeline in the home, relevant manufacturers have introduced water purifiers with various functions to facilitate the removal of substances harmful to the human body and provide relatively harmless drinking water for human beings. However, this kind of conventional structural type has found that the following problems still exist in the actual use experience: the filter elements of the existing water purifiers have only a single water purification function, and therefore, the multi-tube filter elements are usually arranged side by side, so It takes up a limited space in the kitchen.

The net body 40 is mounted on the filter column 30 and the top cover 50 of the net body 40, so that the upper cover 50 and the bottom cover 10 are used to limit the filter column 30 and the net body 40 to form a complete cylindrical filter structure. Referring to FIG. 4, when the water body sequentially penetrates the filter column 30 and the inner tube 20, the filter column 30 and the inner tube 20 having different filtration characteristics can be used for secondary filtration, thereby providing better filtration. Water effect.

The bottom of the bottom cover 10 is formed with a through hole 11 , and an inner edge of the through hole 11 and an outer edge of the bottom cover 10 respectively extend upwardly to form a first skirt 12 and a second skirt 13 , wherein the through hole 11 The water body after the filtration is used out.

The bottom of the inner tube 20 is provided with a sleeve portion 27 connected to the first skirt 12. The inner tube 20 is formed with at least one plane, and the at least one surface is formed with an opening 21, and the inner tube 20 is provided with a filter material 22 for closing the at least one opening 21, wherein the filter medium 22 and the filter column 30 are disposed. There are different filtration characteristics, for example, the filter column 30 can be used to filter particles and impurities in the water, and the filter material 22 can be used to filter heavy metals or toxic substances in the water. In order to provide better support for the filter material 22, a plurality of support rods 23 are provided in the at least one opening 21. As shown in FIG. 6 , the inner tube 20 is annularly provided with a first rib 24 with respect to the periphery of the at least one opening 21 , and the corresponding support rod 23 is also provided with a second rib 25 . When the filter medium 22 is bonded to the inner tube 20 by high-frequency or thermocompression bonding, the first rib 24 and the second rib 25 are respectively fixed to the filter medium 22 by melting at a high temperature. In the preferred embodiment of the present invention, the inner tube 20 is provided with two planes, and an opening 21 is formed in each of the two planes, and a concave arc portion 26 is disposed at a bottom edge of each of the openings 21.

An accommodating space 31 for accommodating the inner tube 20 is formed in the filter column 30. In the preferred embodiment of the present invention, the accommodating space 31 is a through hole.
