Abstract:
A distilling system for distilling a liquid, comprising:a sealed container including a vaporization chamber for containing the liquid and a condensation chamber;a pressure-reducing device connected with the sealed container for reducing pressure in the sealed container, thereby reducing boiling point of the liquid in the container;a heating device for heating and thus vaporizing the liquid in the vaporization chamber into vapor;a vapor-collecting device comprising a piston for separating the liquid from the vapor and a guide tube for collecting and conveying the vapor generated in the vaporization chamber into the condensation chamber such that a contact area between a level surface of the liquid and the vapor is reduced, and returning of the vapor back to the level surface of the liquid is reduced to improve vaporizing efficiency; anda condensing device for condensing the vapor entering the condensation chamber into distilled liquid;with proviso that said piston is in a slidable sealing contact with an inner periphery of the vaporization chamber and floatable in response to a change in a level of the liquid in the vaporization chamber to forcibly guide the vapor into the condensation chamber via the guide tube.
