摘要： This invention concerns a cleaner head 10 for a vacuum cleaning appliance (2) comprising a rotatable agitator assembly (42) and a main body (12) defining an agitator chamber (40) within which is supported the agitator assembly (42). The agitator chamber (40) comprises a suction opening (28) through which a portion of the agitator assembly (42) projects to engage a surface to be cleaned and an outlet (54) through which, in use, energised dirt particles leave the agitator chamber (40) to enter a rear section (22) of the main body (12) as the agitator assembly (42) sweeps them rearwardly from the surface. The rear section (22) comprises a plurality of deflection panels (50) defining a dust channel (52) extending between the outlet (54) of the agitator chamber (40) and an exhaust outlet (32) of the cleaner head (10) through which the energised dirt particles are drawn from the dust channel (52), and the plurality of deflection panels (50) comprise respective concave surfaces (74, 80, 86) configured to deflect the energised dirt particles from the outlet (54) of the agitator chamber (40) towards the exhaust outlet (32) through a series of sequential collisions.

摘要： A cleaner head for a vacuum cleaning appliance includes a housing, a front agitator and a rear agitator. A suction chamber is located between the front agitator and the rear agitator. A baffle is located within the suction chamber between the agitators. During use of the cleaner head, debris becomes entrained within air drawn towards the suction chamber. Guide members mounted on the housing guide the entrained debris towards the suction chamber, whereas the baffle guides the air upwardly towards a central suction port of the suction chamber.

摘要： This invention relates to a cleaner head (10) for a vacuum cleaning appliance, the cleaner head (10) comprising a main body (12) supporting an elongate agitator bar (36). The elongate agitator bar (36) comprises a rotatable cylindrical body (42) having a first agitator formation (44) extending outwardly therefrom. The cylindrical body (42) defines a first channel (58) that extends along the cylindrical body (42) adjacent the first agitator formation (. The first channel (58) extends around the cylindrical body (42) helically and includes a first channel portion (62) extending around the cylindrical body (42) in a first helical direction and a second channel portion (64) extending around the cylindrical body (42) in a second helical direction that is counter to the first helical direction. The first and second channel portions (62), (64) meet to define an apex (66) of the first channel (58).

摘要： This invention relates to a vacuum cleaner. The vacuum cleaner comprises a filtration chamber with an inner wall and an outer wall, an air inlet arranged to feed air carrying dust particles into the space between the inner wall and outer wall of the filtration chamber and a dirt chute for discharging dirt and/or dust from the vacuum cleaner. A tapered filter is located between the inner wall and the outer wall of the filtration chamber. The tapered filter comprises a narrow end and a wide end, and the narrow end of the filter is located at or proximate to the air inlet and/or the dirt chute.
