Example Embodiment

[0022] Hereinafter, examples of embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this invention is not limited to embodiment shown below, It can change in the range which can achieve the objective of the said invention.

[0023] figure 2 It is a schematic external view which connects the water purification cartridge which concerns on one Embodiment of this invention with a flow-path switch, and uses it as a faucet direct-connection type water purifier.

[0024] figure 2 The shown faucet direct-connection type water purifier 1 is mainly composed of a flow path switch 2 and a water purification filter cartridge 3 . The flow switch 2 is used in a state where it is attached to the faucet via the attachment nut 21 and the water purification cartridge 3 is attached to the side surface.

[0025] The flow path switcher 2 has a function of switching between a flow path for discharging tap water (raw water) from a fauc...

Abstract

The invention provides a filter cartridge for purifying water with large and compact accommodation space of a filter and high filter capacity. The filter cartridge for purifying water is disposed in the shell including a raw water inlet and a purified water outlet, and includes a hollow filament membrane bundle and a powder filter. The powder filter is saved in the inner space of a cylinder vessel formed by an inner wall, an outer wall, an upper wall, and a lower wall. The cylinder vessel includes a tabling part A, one end of the hollow filament membrane bundle is fixed on a sealing cover with a sealing agent, and a part of the part except the end of the hollow filament membrane bundle forms a projection part protruding from the sealing cover. The projection part is accommodated inside of the inner wall, and the sealing cover includes a tabling part B. The tabling part A and the tabling part B tables in a watertight manner, so that the water can go through from the surface of the outer wall on the side of the shell to the surface of the inner wall on the side of the hollow filament membrane bundle on the radial direction of the filter cartridge for purifying water.

Description

technical field [0001] The present invention relates to a water purification cartridge installed in a water purifier. Background technique [0002] In recent years, in households, water purifiers for purifying tap water have been widely used. In these water purifiers, a water purification cartridge containing various filters for purifying tap water is used. As a filter element, generally, powder (granular or powder) activated carbon that removes free residual chlorine, bleach smell, musty smell, trihalomethane, etc. from tap water, and activated carbon that removes turbid components, bacteria, etc. Hollow fiber membrane. The total amount of filtered water that these filters can handle is limited, so users continue to use the water purifier while regularly replacing the water purification cartridge. Therefore, users need a water purification cartridge that is as compact as possible, has a high filtering capacity, and can handle a large total amount of filtered water. [0...
