Suction nozzle

A suction nozzle for a vacuum cleaner comprises a suction chamber, an outlet duct, an underside for engaging a surface to be cleaned, a main suction opening in the underside, which opens into the suction chamber, an auxiliary suction path which opens into the suction chamber and a bleed path in fluid communication with the outlet duct. The suction nozzle further comprises a valve mechanism arranged to open and close the auxiliary suction path and the bleed path, the valve mechanism being movable between a first configuration in which the auxiliary suction path is closed and the bleed path is open, a second configuration in which the auxiliary suction path is open and the bleed path is closed, and a third configuration in which both the auxiliary suction path and the bleed path are closed. 种用于真空吸尘器的抽吸嘴，该抽吸嘴包括抽吸腔；出口管；用于接合要被清洁的表面的下侧部；下侧部中的主抽吸开口，其敞开入抽吸腔；敞开入抽吸腔的辅助抽吸路径，以及与出口导管流体连通的送气路径。抽吸嘴还包括阀装置，其配置为打开和关闭辅助抽吸路径和送气路径，该阀装置可在第配置，第二配置和第三配置之间移动，在第配置中辅助抽吸路径关闭且送气路径打开，在第二配置中，辅助抽吸路径打开且送气路径关闭，在第三配置中辅助抽吸路径和送气路径两者都被关闭。
