In the figure, white circles are positively charged particles, and black circles are negatively charged particles. The positively charged particles leaking out to the front side of the lower suppressing plate 91b reach the charged particle sensor 9 provided above. Further, the air rising on the negative electrode needle 87 side pushes positively charged particles that are about to move away from the charged particle sensor 9 toward the charged particle sensor 9 as indicated by white arrows. In this way, an amount of positively charged particles necessary for detecting positively charged particles contained in the air can reach the charged particle sensor 9.

  Further, by changing the size of the notch 91c provided on the negative electrode needle 87 side on the lower side of the upper suppression plate 91a, the flow spreading from the negative electrode needle 87 side to the positive electrode needle 86 side can be changed. The amount of positively charged particles pushed to the particle sensor 9 side can be changed, the amount of positively charged particles captured by the charged particle sensor 9 is minimized, and positively charged particles and negatively charged particles contained in the air are reduced. Can be detected.

  In the present embodiment, the example in which the charged particle sensor is disposed on the positive electrode needle side has been described. However, even if the charged particle sensor having the negatively charged particle sensor unit is disposed on the negative electrode needle side, the above-described configuration may be adopted. There is an effect.

  The embodiment disclosed this time is to be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the meanings described above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
