Abstract (en)
[origin: CN110384439A] A vacuum cleaner nozzle (2) includes a bottom plate (3), wherein the bottom plate (3) has a substantially triangular shape, and is equipped with a lower surface (8), a main dust suction passage (12),and an auxiliary dust suction passage (13). The main suction channel (12) extends transversely to the moving direction of the cleaner nozzle (2). The auxiliary suction channel (13) extends substantially parallel to the moving direction and is fluidly connected to the main suction channel (12). The lower surface (8) of the bottom plate (3) includes a front portion (9), which extends from the frontedge (12a) of the main suction channel (12) to the vicinity of the front tip (6) of the vacuum cleaner nozzle; the front portion (9) of the lower surface (8) is substantially flat and inclined so thatwhen the bottom plate (3) is set on the surface to be cleaned, the front tip (6) of the vacuum cleaner nozzle (2) is closer to the surface to be cleaned than the front edge (12a) of the main suctionchannel (12).
