A device for extracting water from the environment by means of a liquid desiccant, comprising: a) capture means containing liquid desiccant that captures water from the environment; b) an extraction chamber ; c) a first duct through which the liquid desiccant with water flows from the capture means to the extraction chamber ; d) a second duct through which the liquid desiccant flows from the extraction chamber to the capture means ; along the second duct , a pump is connected in order to pump the liquid desiccant toward the capture means ; e) a reservoir to store water extracted from the liquid desiccant in the extraction chamber ; f) a third duct through which extracted water flows from the extraction chamber to the reservoir ; g) a vacuum generator , operationally connected to the reservoir ; h) a valve placed along the third duct ; i) a control device operationally connected to the vacuum generator ; and the pump wherein, when valve is opened, the water vapor present in the extraction chamber flows through valve and through the third duct towards the reservoir , due to the vacuum generator generating a vacuum between the extraction chamber and the reservoir , and the vacuum generator whose suction point is operationally connected to the reservoir in order to suction gas contained in the reservoir , and suction the extracted water that flows through the third duct , thereby extracting the extracted water contained in the extraction chamber ; and wherein, when valve is closed, pressure and temperature increase in the third duct , thereby condensing the water present in the third duct due to the vacuum generator that generates a pressure gradient (pressure increase) between the valve and the reservoir , and the vacuum generator whose discharge point is operationally connected to the reservoir in order to deliver gas to the reservoir , thereby creating a pressure gradient (pressure increase) within the reservoir , which is transmitted by the extracted water contained in the reservoir and by the extracted water contained in the third duct into the extraction chamber , thereby increasing the temperature of the extracted water in the duct and in the extraction chamber . a) capture means containing liquid desiccant that captures water from the environment; b) an extraction chamber ; c) a first duct through which the liquid desiccant with water flows from the capture means to the extraction chamber ; d) a second duct through which the liquid desiccant flows from the extraction chamber to the capture means ; along the second duct , a pump is connected in order to pump the liquid desiccant toward the capture means ; e) a reservoir to store water extracted from the liquid desiccant in the extraction chamber ; f) a third duct through which extracted water flows from the extraction chamber to the reservoir ; g) a vacuum generator , operationally connected to the reservoir ; h) a valve placed along the third duct ; i) a control device operationally connected to the vacuum generator ; and the pump wherein, when valve is opened, the water vapor present in the extraction chamber flows through valve and through the third duct towards the reservoir , due to the vacuum generator generating a vacuum between the extraction chamber and the reservoir , and the vacuum generator whose suction point is operationally connected to the reservoir in order to suction gas contained in the reservoir , and suction the extracted water that flows through the third duct , thereby extracting the extracted water contained in the extraction chamber ; and <EOS>
