Description
Technical field
The present invention relates to a kind of floor nozzle that is used for vacuum cleaner, it has and is used to inhale first POF of sweeping wide ground and is used to inhale second POF of sweeping narrow ground.
Background technology
By the known a kind of floor nozzle of DE-C10017705 with above-mentioned functions characteristic.The suction nozzle of known floor nozzle has one by two broadsides and two bottom sections that narrow margin is fixed, and this zone is rectangle substantially, and can be connected to suction line by means of a biaxial joint, and this joint comprises a suction passage.This joint construction is a universal joint and has a suction nozzle Connection Element that this suction nozzle Connection Element inserts in the depression of the suction nozzle that is configured to half shell.Be difficult to the parts that move relative to each other of sealing universal joint.
By the known a kind of floor nozzle that is used for vacuum cleaner of DE-A10241055, its suction nozzle can be turned over 90 ° by means of the rotation of the suction line that connects, thereby wide ground and narrow ground all can be clean by cleaning.
A biaxial joint is set between suction line and suction nozzle, and this joint is connected with described pipe fitting with one by a T shape pipe fitting and the tubular corner of rotating is formed.Described T shape pipe fitting is mounted between two tubulose receiving members and rotates, and the tubulose receiving member is arranged on the top of suction nozzle and towards the inside opening of suction nozzle.Described pipe bend has about 90 ° curvature, thereby is used for inhaling when sweeping narrow ground when the floor dust absorption nozzle, and free link is positioned at parallel with pivot center basically plane.
When operation during floor nozzle, in proal process, suction nozzle is pressurized owing to be connected to thrust that a suction line of joint causes.The orientation of suction line has pre-determined this line of action of force.In known embodiment, when wide ground was swept in suction, pressure acted on the front area of suction nozzle, and this is unfavorable for mobile advancing.Especially, this suction nozzle is difficult to move on carpet fold and edge of carpet.
By the known a kind of inclination joint that is used for the floor nozzle of vacuum cleaner of EP-B1367931, this joint is made up of the passage connector that is arranged on suction nozzle rigidly and movable channel parts that insert the passage connector and pivot.Under the situation that tilts to move, described parts are done stretching motion towards another.The joint axis of inclination joint is towards the Background Region displacement of suction nozzle, and this helps operating floor nozzle.But this known floor nozzle only is suitable for inhaling sweeps wide ground.This floor nozzle can not be turned over 90 ° with respect to suction line.
Summary of the invention
The present invention is based on and point out that a kind of task of being used for the floor nozzle of vacuum cleaner, the described floor nozzle that is used for vacuum cleaner are suitable for inhaling and sweep wide ground and narrow ground, alcove for example, and also be suitable for the uneven zone on floor.
Purpose of the present invention and the scheme that is used for this task are a kind of floor nozzles that is used for vacuum cleaner, and it has and is used to inhale first POF of sweeping wide ground, and is used to inhale second POF of sweeping narrow floor surface, and has:
Suction nozzle, it has by two broadsides and two bottom sections that narrow margin is fixed,
Inclination joint, it is made up of the passage component that is molded in the passage connector on the described suction nozzle and can pivot, and
Tubular corner, its demonstration is connected with the movable passage component of described inclination joint for about 90 ° curvature, and demonstration is the link that is used for suction line,
Thus, at described first POF, described movable passage component pivots out, thereby the pivot center that is rotationally connected between described tubular corner and the described movable passage component is oriented in downward place, inclined-plane towards ground, thus at described second POF, described movable passage component pivots in the into described passage connector, up to the described pivot center horizontal orientation that is rotationally connected.At described first POF, the broadside of described suction nozzle is orientated the suction line that is basically perpendicular to the connection end that is connected described tubular corner.In the proal process of floor nozzle, in described suction nozzle, introduce thrust, the line of force of described thrust is arranged on being arranged in along the zone at the rear portion of pushing direction of dust absorption nozzle thus.Be positioned at along pushing direction on the anterior broadside, described suction nozzle can easily be carried out banking motion, thereby is easy to through carpet fold and edge of carpet.Floor nozzle according to the present invention is characterised in that good sliding capability on the ground.In addition, this device equal easy operating when wide ground and narrow ground are swept in suction.
The range of pivot of described movable passage component is limited by retainer, and if a retainer distribute to described second POF, then be practical.
According to a preferred embodiment of the present invention, the joint axis of described inclination joint is arranged in the zone between two broadsides of described suction nozzle, and distance is positioned at along the broadside certain distance of inhaling the rear portion of sweeping direction.If described suction nozzle has breach, this breach then is practical being positioned at the free space that moves along the tubular corner that is formed for being connected to described movable passage component on the broadside of inhaling the rear portion sweep direction.In this connected, the joint axis of described inclination joint preferably was arranged in the described breach, near the zone floor of being arranged in of described suction nozzle.The good especially introducing of result is used for the power of thrust.
In another embodiment, the present invention has instructed described suction nozzle to have top shell component and the insert that is connected with this top shell component, and the passage connector of described inclination joint is made up of two parts, a part is molded on the described top shell component thus, and another part is molded on the described insert.Described suction nozzle is a plastic components.The two-piece construction of described suction nozzle has been simplified the mould of injection-molded.If the outer surface of described passage connector is molded on the described top shell component,, then be practical if described insert has the moulded parts of the interior outline portion that forms the geometry that is fit to described movable passage component.
Below described suction nozzle the slip bottom surface can be set in known manner, this slip bottom surface has the suction nozzle that extends to described narrow limit along any direction, and described suction nozzle flows with described passage connector by means of a perforate and is connected.
