Abstract

La présente invention concerne un dispositif (100) pour nettoyer une surface optique (150, 310) d'un véhicule à moteur. Le dispositif (100) comprend : un boîtier (105, 305) ayant un passage d'entrée d'air (110) et au moins une ouverture de décharge (115) ; un composant rotatif (120) ayant un moyeu (125), une paroi périphérique circonférentielle (135) et une pluralité de lames incurvées espacées circonférentiellement et au moins deux canaux de guidage d'air (140) configurés pour générer au moins un faisceau de flux d'air (155a, 155b). La paroi périphérique circonférentielle (135) comprend au moins deux fentes (145) le long d'un périmètre de la paroi périphérique (135), dans laquelle chaque fente (145) s'aligne avec chaque canal de guidage d'air (140) à son extrémité de sortie (140b) et est configurée pour décharger le au moins un faisceau de flux d'air (155a, 155b) sur la surface optique (150, 310) pour balayer la surface optique (150, 310) lorsque chaque fente (145) s'aligne avec l’au moins une ouverture (115) pendant la rotation du composant rotatif (120).
