Self-moving vacuum cleaner
First Claim
1. A self-moving vacuum cleaner comprising:
- a casing having a bottom wall which has leading and trailing ends opposite to each other in a longitudinal direction;
a duct disposed in said casing and having a vacuum inlet which extends downwardly of said bottom wall;
an impeller disposed in said casing and downstream of said vacuum inlet so as to draw dust from a floor surface through said vacuum inlet into said duct; and
an intake nozzle including a tubular nozzle body which is disposed upstream of said vacuum inlet, and which has a lower end that is adapted to trail on the floor surface, and an upper end that extends upwardly from said lower end, that is communicated with and that is retainingly slidable relative to said vacuum inlet, said upper end being configured such that said lower end is movable relative to said vacuum inlet between upper and lower positions so as to be close to and away from said vacuum inlet, respectively, and an anchoring member which is disposed opposite to said tubular nozzle body in the longitudinal direction and proximate to said leading end, and which is hinged to said bottom wall about a hinge axis transverse to the longitudinal direction such that said tubular nozzle body is swingable about the hinge axis between the upper and lower positions in response to unevenness of the floor surface, thereby enabling said lower end to keep trailing on the floor surface when said casing advances with said leading end.

Abstract
A self-moving vacuum cleaner includes a duct disposed in a casing and having a vacuum inlet which extends downwardly of a bottom wall of the casing, and an impeller disposed to draw dust from the floor surface through the vacuum inlet into the duct. An intake nozzle includes a tubular nozzle body which has an upper end communicated with and retainingly slidable relative to the vacuum inlet so as to enable a lower end of the nozzle body to be movable between upper and lower positions, and an anchoring member which is hinged to the bottom wall such that the nozzle body is swingable between the upper and lower positions in response to unevenness of the floor surface, thereby enabling the lower end to keep trailing on the floor surface when the casing moves.
