9. A method for detecting heavy metal content in a traditional Chinese medicine product, using the device for detecting heavy metal content in a traditional Chinese medicine product as claimed in claim 8, characterized in that: The detection method comprises the following steps: Step 1: Powdered Chinese medicine is mixed with nitric acid and hydrogen peroxide. After the mixing is completed, a digestion tank (8) is placed in a digestion instrument body (1). The digestion instrument body (1) starts to work and a drive motor (1501) is started. The drive motor (1501) drives each extrusion plate (1503) and a sealing air bag (1508) to rotate, thereby fully stirring the mixture, accelerating the flow of the mixture, and causing the mixture to heat up and increase pressure more quickly. Step 2: After digestion is completed, electromagnet 2 (2106) is turned off and electromagnet 1 (2102) is turned on, so that electromagnet 1 (2102) adsorbs iron block 1 (2103). When the driving motor (1501) drives the driving shaft (1509) to rotate, iron block 1 (2103) drives the shielding plate (2101) to slide in the annular guide rail (2104), so that the through hole (2108) below the shielding plate (2101) is exposed to the outside, and the mixture falls into the lower placement frame (9) along the through hole (2108), and the extraction pump (14) is started, and the extraction pump (14) guides the mixture into the spray nozzle (2201); Step 3: Adjust the electric telescopic rod (2203) to drive the spray nozzle (2201) to move to the bottom of the mixing barrel (3), and slowly introduce pure water into the mixing barrel (3). The mixture is evenly spread in the introduced pure water through the spray hole (2202). As the amount of pure water introduced increases, the electric telescopic rod (2203) drives the spray nozzle (2201) to gradually rise, so as to achieve layer-by-layer spraying and mixing. After the mixing is completed, open the pipe valve (13), and the liquid enters the mass spectrometer body (6) along the introduction pipe (12), and the mass spectrometer body (6) starts to work.
