However, if the porous hollow fibers 1 are formed to be hydrophilic in this way, when air is mixed into the water in the filtration chamber 4, this air will be absorbed by the hydrophilic porous hollow fibers 1 at a normal pressure of about 1 kg/cm2. There was a problem in that air could no longer pass through the membrane, and therefore air would accumulate in the filtration chamber 4, reducing the contact area between the porous hollow fibers 1 and water, resulting in a reduction in the amount of purified water. . Therefore, Fig. 3(a)(b)

This is controlled by the wall thickness of the transparent membrane 1a, and the wall thickness is formed thin in order to allow air to pass through well. However, since the porous hollow fiber 1 is in the form of a plastic tube, it is easily crushed by external pressure, and the hydrophobic membrane 1a of the porous hollow fiber 1 is crushed and clogged due to an increase in water pressure in the filtration chamber 4. There is a risk that you may be If the hydrophobic membrane 1a of the porous hollow fiber 1 is crushed and blocked in this way, air will not be able to pass through it, and water will also be blocked from passing through the porous hollow fiber 1, resulting in an overall blockage. As a result, the efficiency of filtration will decrease. Furthermore, when the efficiency of filtration decreases in this way, the water pressure inside the filtration chamber 4 increases, creating a vicious cycle, and the membrane that has been crushed once becomes more likely to be crushed again, resulting in this phenomenon occurring frequently. .

徴とする浄水カートリッジ。Claim 1: An end portion of a hydrophilic porous hollow fiber is embedded and fixed in a partition plate with its open end exposed on one surface, and the partition plate provided with the porous hollow fiber is attached to a cartridge cylinder. In a water purification cartridge that is installed inside the cartridge cylinder and partitions the inside of the cartridge cylinder into a filtration chamber on the porous hollow fiber side and an outflow chamber on the side where the open ends of the porous hollow fibers are exposed, there is a gap between the partition plate and the cartridge cylinder. A water purification cartridge characterized in that a sealing material made of a hydrophobic porous material is provided in the cartridge to allow air to pass from the filtration chamber to the outflow chamber via the sealing material.

An end portion of a hydrophilic porous hollow fiber is embedded and fixed in a partition plate with its open end exposed on one surface, and the partition plate provided with the porous hollow fiber is attached to a cartridge cylinder. In a water purification cartridge, the partition plate is made of hydrophobic porous fibers and is formed by partitioning the inside of the cartridge cylinder into a filtration chamber on the porous hollow fiber side and an outflow chamber on the side where the open ends of the porous hollow fibers are exposed. A water purification cartridge characterized in that the water purification cartridge is made by the body and is configured to allow air to pass from a filtration chamber to an outflow chamber via a partition plate.
