Intelligent energy-saving multi-channel particle sampler

The utility model discloses an intelligent energy-saving multi-channel particle sampler, which comprises a single-chip microcomputer, air passages and an air extracting pump connected with the air passages; a keyboard and a display are arranged on the single-chip microcomputer; and each air passage comprises a particle cutter, a temperature sensor, a pressure sensor and a flow sensor which are sequentially connected. The sampler is characterized in that the air extracting pump is connected with at least two air passages in parallel through a coupling; electrically-operated valves are arranged between the coupling and the air passages; and the temperature sensor, the pressure sensor, the flow sensor, the electrically-operated valves and the air extracting pump are respectively connected with the single-chip microcomputer. The utility model adopts one sampler to control N electrically-operated valves to collect N (N is equal to 2 to 10) particle samples, therefore the transportation and warehouse storage expens
