Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a vacuum cleaner nozzle. Background Art

[0002] The shell of an existing vacuum cleaner nozzle is usually made of plastic. Since dust and other cleaning materials are easily adsorbed on fabric or leather surfaces such as sofas, curtains and bedding, in order to improve the dust collection effect, at least one thin rib is generally provided inside the shell of the vacuum cleaner nozzle, and a soft flannel is provided between the shell and the thin rib. The flannel loosens the dust and improves the dust collection effect. The thin rib is usually a flat plastic rib. When the top of the thin rib is higher than the soft flannel, the flannel can be prevented from degumming and falling off to a certain extent. However, there are defects such as poor dust disturbing effect and damage to the textile or leather surface by the thin rib; when the top of the thin rib is lower than the soft flannel, it has a better dust disturbing effect and can avoid damage to the textile or leather surface to a certain extent. However, there are problems such as degumming and warping and falling of the flannel.

[0003] Chinese invention patent CN104905733B discloses a vacuum cleaner head suitable for textiles, which achieves dust disturbance effect by setting a flapping plate, thereby further improving the vacuuming effect. However, the flapping plate in this solution still has the problem of scratching the textile or leather surface. Utility Model Content
