The invention discloses a device of a portable efficient air sampler, which comprises three main parts, namely a sampling part, an air extractor and a power part, wherein the sampling part consists ofa sampling head, a gland, a filter membrane clamp and a flow meter; the air extractor is formed by connecting two stages of centrifugal fans in series, has relatively high negative pressure, can meetthe requirement of dust measurement, and is a core part of the sampler; in the power part, each stage of fan is driven by a motor, and the power of motor operation is directly connected with a powersupply. According to the design, the sucking pump, the flow meter, the main sucking pipe, the branch sucking pipe, the bubble bottle, the lifting supporting legs, the middle mounting plate, the branchsucking pipe, the hinged mounting plate and the pipe body sleeve are arranged on the mounting plate, so that the effect of completing air sampling operation of a plurality of rooms at a time is achieved. The device has the advantages of reasonable and effective air inlet sampling structure, high stability, easiness in disassembly and assembly, convenience in carrying, simplicity and quickness insampling operation, flexible and adjustable sampling height, good sampling effect at multiple positions through one-time sucking and high representativeness.
Description
technical field [0001] The invention relates to the technical field of atmospheric sampler preparation, in particular to a device for a portable high-efficiency atmospheric sampler. Background technique [0002] In the prior art: the patent announcement number of CN 205749042U discloses an air sampler, including several bubble bottles, flow meters, branch air extraction pipes, main air extraction pipes and air extraction pumps, at least two groups of air bubble bottles respectively pass through the branch air extraction pipes After being connected in parallel, it is connected to one end of the main exhaust pipe, and the other end of the main exhaust pipe is connected to the suction port of the air pump, and a flow meter is connected to the pipeline of the main exhaust pipe. However, the indoor air sampler in this patent has the problems of uncompact structure and complicated air extraction operations. Contents of the invention [0003] The technical problem to be solved b...
