The deflector (2) is adhered or welded to the filter material of the bag wall, inside the bag. The deflector is arranged on the panel (4) holding the bag in the vacuum cleaner, and extends into the interior of the bag. The deflector divides the flow between two different directions. It partly surrounds the inlet opening, fastened to the interior. It has at least one deflection surface opposite the opening. Its area exceeds that of the inlet opening. The deflector has two trapezoidal or rectangular deflection surfaces, running out in a wedge-shaped configuration, starting from the inlet opening. Their connecting edge lies opposite the inlet opening. A box-like modification of the deflector is described. This is designed to fold out from a substantially flat form, which closes the opening. It includes a spring (7) permitting folding-out in response to the suction flow. Suitable fold lines (6) are included. An inlet opening seal (8) is included; it is made of rubber, elastomer, film or foam. The deflector is plastic, wet- or dry-laid fleece, paper, card or a film. The holding panel and deflector are made of plastic. They form an integral construction. |
