L'invention concerne également un climatiseur (100) qui comprend une unité intérieure de climatisation et le générateur d'ions positifs et négatifs (200). Lorsqu'un écoulement d'air souffle directement sur la sonde (240) et passe à travers le canal d'écoulement (201), la pression dans une zone de la sonde (240) est augmentée, et, à ce moment, l'écoulement d'air est compensé au moyen de son entrée dans le canal (201) par le premier trou de perturbation (231), afin d'équilibrer la pression interne et d'éviter la formation d'une région de vortex à pression négative autour du corps (210) de générateur, ce qui permet d'éviter la formation de condensation sur le corps (210) de générateur, aidant un utilisateur à mieux utiliser le générateur d'ions positifs et négatifs (200).
