The invention provides an unpowered air source water drawing device and method applied to an arid region, a water drawing device body comprises a condensate water collecting cavity located on the lower portion, an air condensation cavity is arranged above the condensate water collecting cavity, and a chimney type air duct is arranged above the air condensation cavity; the condensate water collecting cavity, the air condensing cavity and part of the chimney-shaped air duct are buried in the soil body, and an exhaust port is formed in the top of the chimney-shaped air duct; a photovoltaic PN junction patch for generating current is adhered to the outer wall of the upper part of the chimney-shaped air duct, and is electrically connected with an energy storage device and a refrigeration PN junction patch through a controller; the refrigeration PN junction patch is arranged on the air condensation cavity in a pasted mode and electrically connected with the energy storage device at the same time. An air inlet pipeline is arranged in the air condensation cavity, extends out of the chimney-shaped air duct and is used for introducing air; and a water collecting device is arranged in the condensate water collecting cavity. The device can be used for water drawing operation in the desert environment.
