Abstract: A filtration cartridge of a liquid purification device that consists of a filtration zone (1) and a venting zone (6), said filtration zone in turn consists of a housing (2) filled with a filtration material (3) and not less than one opening (5) made in the bottom (4) of the housing (2), said venting zone consists of fixation means (7) and a lid (8), performed so that the filtration material (3) has a multi-clustered interconnected structure, and the venting zone (6) is formed so as to retain and preserve the main structure of the filtration material (3) inside the housing (2) of the filtration cartridge, by means of the fixation means (7) being the first retention barrier and made as a grid, the size of mesh (11) of said grid does preferably not exceed the average size of the filtration material cluster, and the lid (8) is made as a second retention barrier and formed, with meshes (12) comprising net sections and a top point (9) of the lid (8) is positioned at a distance preferably not more than 1 cm above th

Abstract: The invention belongs to liquid predominantly to water purification devices which are used as off line units in household, outdoors, in the village and service departments. Particularly the given invention is in the filed of pressure off-line units. The invention can be used for water purification and other liquids of household use, in medicine and other branches of industry. Liquid purification device, operating under gas pressure and containing raw liquid vessel with the spout, lid, filtration cartridge, purified liquid vessel, output purified liquid means, the gas injection block, connected to raw liquid vessel, and containing gas injection means, control panel and power supply, characterized in that the liquid purification device is capable of at least two stage opening of the lid and the pressure relief down to atmospheric is on the first stage.

Abstract: The invention relates to water purification devices of gravity type, intended for final purification of tap water and other liquids for household purposes. From the state of the art water purification devices of gravity type usually consist of three elements: container for the raw liquid and container for purified liquid, which communicate with each other through water filtration cartridge. Raw liquid is poured into container for raw liquid and under gravity forces it flows through filtration cartridge and collects in the container for purified liquid. As it is known filtration cartridge consists of filtration zone and venting zone. Venting zone is executed as the lid with openings for raw liquid inflow and air outflow, and filtration zone. Filtration zone has in its bottom not less then one opening for purified water outflow and as usual is filled with filtration material. For example granulated and fibrous sorbents can be used as filtration materials in such purification devices.
