    • The present invention discloses a sample feeding device for an ion mobility spectrometer, which is adapted to guide a sample to be detected into an inlet of a drift tube of the ion mobility spectrometer. The sample feeding device comprises a solid sample feeding component; a sample inlet component; a attachment component, wherein the solid sample feeding component has an internal cavity defined therein, one end of the solid sample feeding component is communicated with the sample inlet component through the internal cavity, while the other end is communicated with the inlet of the ion drift tube through the attachment component; and a gaseous sample feeding component, comprising a body and an external attachment component, the body has a gas channel therein, and the external attachment component includes an inlet hole which is communicated with the gas channel, wherein when the external attachment component is fitted with the sample inlet component, the body is inserted into the internal cavity, so that a channel of the solid sample feeding component is closed, and only the gas channel of the gaseous sample feeding component is communicated with the inlet of the drift tube of the ion mobility spectrometer.
