Laboratory intelligent universal air extracting system

The invention discloses a laboratory intelligent universal air extracting system. A controller controls a first driving device and a second driving device to drive an air guide pipe to move and bend according to detecting data of a gas sensor, so that an air extracting cover is positioned in an area of the gas sensor with abnormal detecting data; an air guide device is controlled to extract air, wherein the air guide pipe is formed by spherically connecting multiple pipe joints in sequence to form an air extracting channel; the air guide pipe is high in firmness and excellent in flexibility; and the air extracting cover can flexibly move along with the air guide pipe, and can randomly position the direction to effectively and quickly exhaust poisonous gas and dust in different areas of a laboratory in a fixed direction so as to guarantee the safety of the laboratory. The laboratory intelligent universal air extracting system, proposed by the invention, can automatically position the direction according to sensor detecting signals, and can effectively and quickly exhaust the poisonous gas and dust in the laboratory, so that the use is convenient; and meanwhile, the air guide pipe is liable to be assembled and disassembled, so that the length of the air guide pipe can be increased or decreased according to the use range demands.
