Water Purification Device and Method for Operating a Water Purification Device

Invention relates to a water purification device comprises a water collecting device having a surface defining a variable volume and comprising a filter membrane permeable to water. The device comprises an expansion device for exerting a force for increasing the volume of water collecting device and thereby drawing water through the filter membrane into the water collecting device. The expansion device comprises a support structure supporting the filter membrane, wherein the support structure can be elastically deformed and is designed to settle snap, after being deformed, into one of at least two discrete stable configurations, a first one of these stable configurations being a low volume configuration of the support structure, a second one of these stable configurations being a high volume configuration of the support structure.
