MOBILE DEVICE FOR FILTERING LIQUID UNDER PRESSURE

摘要

A device for filtering liquid, including a first reservoir for collecting filtered liquid, a second reservoir for liquid to be filtered, the second reservoir contained at least partially in the first reservoir, the walls of said second reservoir having at least a filtering opening allowing transfer of liquid between the first and second reservoirs, an injection opening having a filter blocking the filtering opening, and a flexible pressurization device to inject air into the second reservoir via the injection opening. The pressurization device is located completely outside the second reservoir, and has a volume that is variable between two positions: a deployed position, in which the volume of the pressurization device is maximal, and a folded position, in which the volume of the pressurization device is minimal.

1. Filtration device comprising:
a first reservoir adapted to collect filtered liquid, a second reservoir adapted to contain liquid to be filtered, said second reservoir being contained at least partly in said first reservoir, walls of said second reservoir having at least two openings: a filtration opening, suitable for transferring liquid between said first and said second reservoir, and an injection opening, a filter closing off said filtration opening, a pressurization device for injecting air into said second reservoir through said injection opening, such that said pressurization device is a flexible device, completely located outside said second reservoir, and occupying a variable volume between two positions: a deployed position in which the volume occupied by the pressurization device is at a maximum, a folded position in which the volume occupied by the pressurization device is at a minimum,and wherein said folded position is, in the absence of any action by a user, a stable position.
