An automatic rapid detecting device

The invention discloses an automatic rapid detecting device, which has reasonable structure and ingenious design. The biggest characteristic of the device is that a unique double enrichment purification switching design and mutual switching and cooperation of multiple valves are utilized, and therefore, enrichment purification and sample feeding are separated in a whole analysis experiment, enrichment purification in a second passage can be performed at the same time when sample feeding and analysis are performed in a first passage, enrichment purification in the first passage can be performedat the same time when sample feeding and analysis are performed in the second passage, and so on; the unique double enrichment purification switching technique greatly shortens the analysis cycle ofeach sample, greatly increases the using efficiency of an instrument, and reduces the average cost for sample analysis; functions of a plurality of sets of processing and detecting devices are achieved with one instrument, thu
