摘要： The invention discloses a safety inspection detector and a goods safety inspection system. The safety inspection detector at least comprises a circuit board, a first housing, a second housing, a detection module and a connecting interface. The detection module and the connecting interface are mounted on the circuit board. The first housing is pressed and connected to a first surface of the circuit board, and the second housing is pressed and connected to a second surface of the circuit board. The first housing and the second housing can hermetically wrap the detection module and electronic devices on the circuit board, but bypass the connecting interface to realize leading-out and connection with related interconnected cables by utilizing the connecting interface. The housings can be used for sealing and protecting sensitive electronic devices in the detector, thus being moisture proof and preventing interference.

摘要： The present invention provides a corona discharge device, comprising a first electrode including: a first substantially cylindrical inner chamber portion and a second substantially conical inner chamber portion in communication with the first inner chamber portion, wherein the second inner chamber portion has a cross sectional area that gradually enlarges in a direction away from the first inner chamber portion. The present invention also provides an ion mobility spectrometer comprising: an ionization region; and the corona discharge device disposed in the ionization region. With the above construction and structure, the ion mobility spectrometer of the present invention has the advantages that extraction of ions is facilitated and a life time of the corona electrode is lengthened. In addition, the focusing and storing electrode is used to effectively shield interference of a corona discharge pulse, and to push and focus sample ions. A designed voltage control solution is used to achieve mobility differentiating of ions, while a corona pulse is shielded to prevent variation in an ion quantity due to the corona pulse, thereby achieving an effect of stabilizing mobility spectrum lines.
