Extraction device for solid medicine component analysis

The invention relates to the technical field of medicine analysis instruments, in particular to an extraction device for solid medicine component analysis, which comprises an external solution cylinder, a solid accommodating cylinder, a filter layer, an airtight turncap, a separated fan blade rod, a driving separation insertion cylinder and a driving machine, the filtering layer is arranged on the surface of the lower end of the solid containing cylinder, the airtight turncap is spirally installed at the position of the lower end of the solid containing cylinder, and the filtering layer is clamped and fixed between the surface of the lower end of the solid containing cylinder and the lower surface of the interior of the airtight turncap; the elastic locking structure drives the solid containing cylinder to move upwards in the external solution cylinder, so that negative pressure can be formed in the space, located below the solid containing cylinder, in the external solution cylinder, and the filtering speed
