Abstract

An automatic gas sampler comprises a base (10); a sampling means (20), which comprises a group of sampling electromagnetic valves (21), a gas sampling pump (22), a syringe base (23), a syringe (24) set on the syringe base (23) and multiple sampling containers (25); a positioning means (30), which comprises a sideward shaft (31) set on the base (10), said shaft could be rotatablely up-and-down, an upper and a lower cylinder supporting means (32,33) transversely set on the sideward shaft (31), and a blocking arm (34) for sampling containers (25), a cylinder fixed base (321) is respectively set on the upper and the lower cylinder supporting means (32,33); a driving means (40), which comprises a gas pump (41) set on the base (10), an electromagnetic valve (42) for driving the syringe and an electromagnetic valve (43) for withdrawing the syringe, and a bi-directional cylinder (44) set on the cylinder fixed base (321); a supporting means (50), which comprises a principal shaft (51), a guiding plate (52), a guiding arm (54) and a sampling plate (55), the principal shaft (51) is set on the center of the base (10), the guiding plate (52) and the sampling plate (55) is axially installed on the principle shaft (51), a spiral guiding groove (521) is set on the top surface of the guiding plate (52) with tooth (524) on the circumference; a control means (60) for controlling the motion of the sampling means (20) and the driving means (40); a power supply (70). The invention is adapted to the environment protecting field and could meet the demand of sampling while monitoring the air quality.
