Vacuum cleaner with articulated suction port assembly
First Claim
1. A suction port assembly of a vacuum cleaner, the suction port assembly being connected in fluid communication with a cleaner body through one or more extended flow passages which include at least one of an extension pipe and an extension hose, the suction port assembly comprising of:
- a suction head having a suction hole formed at a bottom surface;
at least one first connection member extending from one side of the suction head;
a second connection member rotatably connected at one end to an exit end of the first connection member and rotatable about a first axis to move upwardly and downwardly with respect to the suction head, and the other end of the second connection member being connected with the extended flow passage; and
a third connection member engaging the second connection member with the extended flow passage being in fluid communication therewith, whereby the third connection member rotates with respect to the second connection member about a second axis which is substantially perpendicular to the first axis, and the second connection member including a first connection opening connected in fluid communication with the suction hole and located at the end which is connected with the third connector member, and a first connection boss extending from an inner sidewall of the second connection member toward the first connection opening, the first connection boss having a screw piercing hole at a lower end thereof,wherein air is drawn in through the suction hole during the vacuum cleaning operation, passes through the first connection member and the second connection member and into the extended flow passage.

Abstract
A suction port assembly of a vacuum cleaner is connected with a cleaner body by an extended flow passage and draws in air and dust from a surface being cleaned when the cleaner is in operation. The suction port assembly includes a suction head having a suction hole formed at a bottom surface opposite to the surface being cleaned. A first connection member extends from one side of the suction head. A second connection member rotatably connects at one end to an exit end of the first connection member and rotates about a first axis to move upwardly and downwardly with respect to the suction head, and at the other end is connected with the extended flow passage. A third connection member engages the second connection member with one end rotatable about a second axis substantially perpendicular to the first axis, and the other end disengageably connected to the extended flow passage.

10. A vacuum cleaner comprising:
-
a cleaner body housing a vacuum generator therein; an extended flow passage connected to the cleaner body in fluid communication with the vacuum generator; a suction head rotatably coupled at an end of the extended flow passage, and having a suction port which is connected in fluid communication with the extended flow passage; and an articulated portion connecting the suction head and the extended flow passage in a rotatable manner about a plurality of axes, wherein the articulated portion includes, a pair of first tubular connection members protruding from the suction head, a second connection member connected to the tubular connection members in a rotatable manner about a first axis, and a third connection member connected to the second connection member in a rotatable manner about a second axis, and connected with the extended flow passage, wherein the second connection member includes a first connector opening connected in fluid communication with the suction hole and located at the end which is connected with the third connection member, and a first connection boss extending from an inner sidewall of the second connection member toward the first connection opening, and having a screw-piercing hole at a lower end thereof. - View Dependent Claims (11)

12. A suction port assembly of a vacuum cleaner for drawing in air and dust from a surface being cleaned when the vacuum cleaner is in operation, the suction port assembly being connected in fluid communication with a cleaner body through one or more extended flow passages which include at least one of an extension pipe and an extension hose, the suction port assembly comprising:
-
a suction head having a pair of suction holes formed at a bottom surface thereof opposite to the surface being cleaned and a connection recess in abutment with the pair of suction holes, and the suction head including a pair of inner flow passages formed in the suction head to connect the pair of suction holes to a pair of first connection members, with the pair of inner flow passages being isolated from each other in the suction head; and the pair of first connection members extending from one side of the suction head; a second connection member rotatably connected at one end to an exit end of the first connection members and rotatable about a first axis to move upwardly and downwardly with respect to the suction head, and the other end of the second connection member being connected with the extended flow passage, wherein air is drawn in through the suction holes during the vacuum cleaning operation, passes through the first connection member and the second connection member and into the extended flow passage.
