た。However, activated carbon has a property that it exhibits a removal capacity close to 100% at the initial stage of use, but the removal capacity sharply decreases thereafter.
Therefore, in reality, the user is actually using the cartridge filter for a long period of time with the removal ability of the cartridge filter lowered. However, even if the removal ability of the cartridge filter is lowered, no perceptible phenomenon occurs, so that the user used without knowing that the removal ability was lowered.

れてくる。When water is passed through the water purifier cartridge filter of the present invention, the water that has passed through the filter material 3 is applied to the pleated water absorbing paper 5. When water is applied to the pleated water-absorbent paper 5, the water-absorbent paper 5 gradually swells and the pleating process is started.

ラミネートすれば止水がより完全になる。When the pleating process is completed, the gap between the water absorbing paper 5 and the water passage port 11 disappears, so that the water passage port 11 is closed. Since water does not flow when the water passage 11 is closed, the cartridge filter cannot be used. The time until the water-absorbent paper 5 swells and can be pleated varies depending on the water-absorbency of the water-absorbent paper 5, but if hard pulp paper is used, the water passage port 11 is blocked in about 4 to 5 hours. Become. Further, if the lower surface of the water-absorbent paper 5 is laminated with a polyethylene film, the water stop will be more complete.

FIG. 1 is a cartridge filter 1 for a water purifier according to the present invention.
FIG. This cartridge filter 1
Is composed of a case lid 2, a filter medium 3, a cup 4, a pleated water absorbing paper 5 and a case body 6, and is fitted into a hole at the bottom of the water purifier body 7 as shown in FIG. Is used.

い。A mesh 8 is formed on the case lid 2, and the water contained in the water purifier body 7 is poured into the filter medium 3 through the mesh 8. The filter material 3 is formed by wrapping the granular palm shell activated carbon 9 in a non-woven fabric 10. For the non-woven fabric 10, it is preferable to use a melt blown non-woven fabric having a fine diameter, which itself has the ability to filter and purify water.

し変更することも可能である。The cup 4 is for partitioning the case body 6 into an upper part and a lower part, and a large number of holes of arbitrary shape are uniformly formed on the bottom surface of the cup 4. Further, the filter material 3 is disposed in the cup 4. The water absorbent paper 5 is a hard pulp paper that is pleated into a corrugated plate shape. The lower surface of the hard pulp paper is preferably laminated with a polyethylene film. It is preferable that the time to stop the water is 4 to 5 hours in consideration of the filtration capacity of the filter medium 3 and the growth time of various bacteria. In addition, the water-absorbent paper 5 may be softened by water absorption, pleated in about 4 to 5 hours, restored to a flat surface, but not melted, and may be appropriately selected and changed from those having the above-mentioned properties. It is also possible.

Reference numeral 1 is a hole having a diameter of about 2 mm, which allows water of about 2 liters per minute to pass therethrough. The pleated water absorbing paper 5 is arranged so as to cover the water passage 11. 12
Is a container for receiving filtered water.

容器１２に落ちる。Next, the process from the start of water flow to the stop of water flow of the water purifier cartridge filter 1 of the present invention will be described.
The water-absorbent paper 5 before passing water has a corrugated plate shape as shown in FIG. When water is put into the water purifier main body 7, the water passes through the mesh 8 of the case lid 2, the filter medium 3, and the holes at the bottom of the cup 4, and then hits the water absorbing paper 5. Further, water is absorbed by the water-absorbent paper 5 and the case body 6.
It reaches the water passage 11 through the space between the bottom and the bottom of the container and falls into the container 12 arranged below.

で、止水したままとなる。When the water-absorbent paper 5 is splashed with water, the water-absorbent paper 5 gradually contains water and swells. When the water-absorbent paper 5 swells, the pleating process is gradually removed, and finally the water-absorbent paper 5 becomes flat as shown in FIG. 4, and the water passage 11 is closed. Once the water passage 11 is closed by the water absorbent paper 5, even if water is put into the water purifier body 7, the water pressure is exerted on the water absorbent paper 5 and pressed down from above, so that the water remains stopped.
【００１７】吸水紙５の下面をポリエチレンフィルムで

で、再使用できない。If the lower surface of the water-absorbent paper 5 is laminated with a polyethylene film, the water passage 11 will be closed by the polyethylene film, so that the water stopping will be more complete. Thus, even if the cartridge filter for a water purifier of the present invention is used again after being used once, when the set time is exceeded, the water-absorbent paper 5 swells and pleats, and the water passage port 11 remains blocked. It cannot be reused.

ある。In the cartridge filter for a water purifier of the present invention, when the set time is exceeded, the water passage port is closed and water is stopped, so that the user does not exceed the removal capacity of the cartridge filter. In addition, since it is not used for a long time, it is hygienic because grown bacteria do not enter the mouth.
