The dielectric tube 1336 is located in the second cavity 1331 . The second cavity 1331 has an inlet 1332 and an outlet 1333 opposite to each other. The second sub-power supply 162 includes a first contact 162a and a second contact 162b, the external electrode 1334 is electrically connected to the first contact 162a of the second sub-power supply 162, and the internal electrode 1335 is electrically connected to the first contact 162a of the second sub-power supply 162.
