A water resource treating device includes an inner tube having a wind inlet section, a front low-pressure section, and a buffering section in series. The front low-pressure section has an inner diameter smaller than an inner diameter of the buffering section. An outer tube is mounted around the inner tube. A flash space is defined between the inner and outer tubes. The outer tube includes a water filling hole and a draining hole both of which is in communication with the flash space. A condensing tank is mounted in the flash space and surrounds the front low-pressure section. The condensing tank is connected to the flash space by a water inlet tube. A water outlet tube is connected to the condensing tank for draining purified water in the condensing tank. A regulator is mounted in the front low-pressure section and controls communication between the inner tube and the condensing tank.

Water resource treating device

A heating and cooling device includes a cylinder having a chamber for receiving a gas. A guiding groove is defined in an inner periphery of the chamber. A piston assembly is movably received in the chamber of the cylinder. The piston assembly includes first and second pistons and a connecting rod connected to the first and second pistons. The first piston is mounted to a side of the second piston and rotatable relative to the connecting rod. Each of the first and second pistons includes a plurality of openings. A guiding block is formed on an outer periphery of the first piston and is slideably received in the guiding groove.
