Abstract

La présente invention concerne une soufflante (1) ayant un ventilateur (20) placé dans un boîtier (10), un dispositif d'entraînement (30) pour faire tourner le ventilateur (20), un cache de protection anti-poussière (60) pour couvrir une ouverture d'admission (11) du boîtier (10) et un mécanisme d'arrêt d'entraînement (70) pour arrêter le dispositif d'entraînement (30). Le mécanisme d'arrêt d'entraînement (70) présente un levier de pression (72) pour appuyer sur un capteur de pression (71) lorsqu'il est pressé par la saillie (65b) du cache de protection anti-poussière (60) inséré dans un trou de montage (12) réalisé dans le boîtier (10) et présente également une section de commande (73) pour arrêter le dispositif d'entraînement (30) lorsque la force de pression exercée sur le capteur de pression (71) par le levier de pression (72) diminue. Le fait que le ventilateur (20) s'arrête automatiquement de tourner lorsque le cache de protection anti-poussière (60) est retiré de l'ouverture d'admission (11) permet d'améliorer la sécurité lorsque l'ouverture d'admission (11) est exposée vers l'extérieur.
