The invention discloses a portable air kettle, comprising: an adsorption component, comprising a heat and
moisture adsorption filler, an elastic bulky piece for attaching the heat and
moisture adsorption filler, and an adsorption accommodating box for accommodating the elastic bulky piece, wherein the heat and
moisture adsorption filler is used to perform heat and moisture exchange with the
hot and humid air to absorb moisture in the air; a separation component, comprising an
extrusion component, a power connection component, and a separation solution collection box, wherein the
extrusion component is used to extrude the elastic bulky piece to separate the solution in the elastic bulky piece, the power connection component is used to drive the
extrusion component to move, and the separation solution collection box is used to receive the solution separated from the elastic bulky piece; a filter component, comprising a
reverse osmosis filter element, wherein the input end of the
reverse osmosis filter element is connected to the output end of the separation solution collection box, and the
reverse osmosis filter element includes a drinking water output end; and a drinking water box, which is connected to the drinking water output end to collect drinking water. The invention can help people complete the function of obtaining drinking water in the wild and meet people's needs for obtaining drinking water when surviving in the wild.
