The comb is pivotally mounted between one so-called active end position, in which the teeth of the comb project from the mouthpiece opening, and an inactive end position, in which the teeth of the comb are retracted into the suction head, the clearing member being pivotally mounted inside the suction head, and the accessory including an actuating mechanism that pivots the comb, and which is distinct from the clearing member. A suction assembly including such an accessory is also described.
