Description
Technical field
The present invention relates in general to the field at suction opening place with the vacuum cleaner nozzle of sealing the margin.
Background technology
Total institute is known, and in order to improve in uneven and on the surface of softness performance, vacuum cleaner nozzle comprises multiple joints of the junction between suction nozzle outlet and extension and/or suction hose.The plurality of joint makes vacuum cleaner nozzle be applicable to this surface, thus draws more dusts when flexible pipe and vacuum cleaner nozzle work above ground or carpet.WO02/26097 discloses a kind of vacuum cleaner nozzle, it is installed pivotally relative to suction nozzle outlet, thus the motion of vacuum cleaner nozzle in forward and backward directions alternately makes two working edges (or sealing the margin of vacuum cleaner nozzle, it is configured to restriction air stream, and described air stream is from the region of the active suction district of the vacuum cleaner nozzle surrounded on soft-surface) in one more closely with the surface contact of cleaning.When cleaning is covered with the ground of carpet (carpet is stranded and has hair, fine hair and other fibrous material), this is favourable.When using the vacuum cleaner nozzle according to the scheme of as above quoted prior art, moving forward and backward during cleaning causes vacuum cleaner nozzle to tilt.When uneven surface, due to this motion, the unexpected decline of the decompression (underpressure) caused by the suction below vacuum cleaner nozzle may cause uncomfortable jump.In addition, on some carpets, the continuation of decompression declines suddenly and increases and causes vacuum cleaner nozzle to vibrate in irritating mode.In WO2009/128763, disclose the suction nozzle alleviating these problems, wherein a part for conduit defines the first elongated protuberance at the suction opening place of suction nozzle.Protuberance provides the extend at least partially first secondary sealing the margin along the first primary seal edge, and protuberance is also from the first primary seal marginal water translational shifting.Sealing the margin is arranged for and engages with just cleaned surface, and at least partly suction opening is directed to just cleaned face seal.
If (namely vacuum cleaner nozzle loses suddenly its close contact with just cleaned surface for some reason, if the first primary seal edge of suction disc is inclined upwardly too far away suddenly from surface), then the size of (underpressuredrop) falls in the decompression that the first secondary sealing the margin can reduce to produce at entrance side.By air conduit wall is arranged to protuberance, when vacuum cleaner nozzle crosses carpet or any textile or soft-surface, and when suction nozzle tilts too greatly to such an extent as to decompression otherwise declines, the control that the decompression of vacuum cleaner nozzle is fallen can be kept better.If the decompression below vacuum cleaner nozzle disappears, so dust collection capacity temporarily reduces, and at this moment again must set up decompression.By allowing decompression to reduce (because the unexpected change of the surface contact on the first secondary sealing the margin and just cleaned surface is less) with less step, suction nozzle obtains the better decompression controlled.And then, due to unexpected decompression, the irritating jump impact that causes is fallen and vibration effect decreases.Therefore, secondary sealing the margin provides better from carpet dust collection capacity and more comfortable clean experience.
Thered is provided the protuberance of the suction opening of the first secondary sealing the margin to imply and manufactured the challenge of suction disc, because cut foundry pattern instrument must insert from the top of suction disc, these needs have sizable opening in the air conduit of suction disc.Alternately, independent parts must be attached to suction disc to form protuberance.
