Atmospheric pressure miniature plasma jet generation device

The invention discloses an atmospheric pressure miniature plasma jet generation device, and the device comprises a power supply, a working gas source, an electrode, a medium container, a gas regulation and control switch, and a dielectric tube. The medium container is hollow and tubular, and is provided with a gas inlet and a gas outlet at different positions. The electrode is disposed on the dielectric container, and is directly connected with the power supply. The gas regulation and control switch is disposed between the working gas source and the gas inlet of the medium container, and is used for controlling the working gas of the working gas source to enter the medium container from the gas inlet of the medium container. One end of the dielectric tube is connected with the gas outlet of the medium container, and the other end of the dielectric tube is provided with a gas outlet. The device can solve a problem that a conventional plasma jet device is difficult to generate and control high-draw-ratio plasma
