The invention aims at improving a vacuum cleaner nozzle of this type, particularly in terms of maneuverability for carpet vacuum cleaning. Therefor, the delimiting elements (5') are designed to be vertically mobile, over a partial zone and said delimiting elements (5') can be automatically lifted, depending on the substrate present in the suction chamber (2) and/or depending on a forward (r) or backward (r') movement of the floor nozzle (1).
Description
The present invention relates to a kind of floor nozzle of dust catcher, it have one along direction of propulsion by delimiting device, for example constituting the suction chamber on border, front and back by slide plate, establish rotatable hairbrush in case of necessity in suction chamber inside.
The floor nozzle of described type is known.Be arranged in suction chamber front side and rear side and for example be the demarcation device of slide plate in form, especially work during operation on the ground of carpeting, this moment, floor nozzle was bearing on the carpet pile by slide plate, and they provide a kind of almost closure of sealing of suction chamber.Here confirmed already disadvantageously, and especially on dense and/or villose carpet, formed high negative pressure in suction chamber, this causes increasing and skid force being increased based on friction.The skid force of described increase makes dust catcher be difficult to use.
In view of above-mentioned prior art, technical problem to be solved by this invention is, the operability the when floor nozzle that improves described type aspirates operation on the ground of carpeting.
Above-mentioned technical problem is at first solved with main theme by claim 1, stipulates in view of the above, and delimiting device can move both vertically by a subregion; And, delimit device and can be depending on the negative pressure that exists in the suction chamber and/or promote automatically according to the forward travel and the setback of floor nozzle.Provide the negative pressure that makes in the suction chamber to be limited to a peaked possibility based on this according to design of the present invention.This value is selected so highly here, makes to guarantee dust suction that is clean-up effect from now on, and negative pressure is selected so lowly on the other hand, makes skid force be in the scope that the user allows.Flow through carpet by additional leaked-in air being close to, thereby can absorb the foul that is in this position on the carpet pile better by selection adjustment demarcation device.Therefore more preferably can promote the demarcation device that maybe can descend is designed to the type of the guiding valve of vertical movement substantially, this in addition effective air guiding valve or thick foul guiding valve or wash away the width of air guiding valve, should be chosen as overall width less than floor nozzle, thereby, further compress by the adjacent demarcation device that does not move such as base plate or slide plate on the ground of carpeting to be processed, demarcation device both sides of motion.It is contemplated that relatively that therewith the width of delimiting the motion parts of device or guiding valve is 50 to 200mm.Can adjust the air capacity that flow in the suction chamber by them, thereby can infer fully this moment guiding valve or the following seamed edge of delimiting device separate with the ground that will clean, until the maximum open that reaches expectation, cleaning power that this maximum open is expected or concrete geometrical condition limit.Preferably, the following seamed edge of guiding valve or the demarcation device that moves both vertically is configured as sealing lip or a kind of slide plate.Here also can constitute thick thing and receive mouth when delimiting the opening that forms when device promotes.In order aspect the dust suction of slit, to be optimized, this big opening is closed by delimiting device, the latter also can be made up of bristle bar section or sealing lip.Relevant therewith, also preferably, order is delimited device along the descent direction pretension.Also rocking arm shape keyer is established in suggestion in floor nozzle, and this rocking arm shape keyer is by a ground segment that sucks in the suction chamber, the carpet section deflection that especially sucts; And, the lifting that device is delimited in the deflection control of keyer.Especially when being dense carpet dedusting, the negative pressure in the suction chamber may increase to, and with carpet or make strong suction the in carpet section ground of suction chamber approximate sealing downwards, thereby carpet pile is invaded in the suction chamber dearly.At this moment the stressed and deflection of rocking arm shape keyer promotes the demarcation device thus and causes adjusting the interior negative pressure of suction chamber.Negative pressure in the suction chamber here is adjusted into and helps causing less skid force.Relevant therewith, also preferably, the starting threshold value (Ansprechwelle) of keyer deflection is adjustable.Can adjust the negative pressure threshold value based on this design, Cai a just value lifting of delimiting device in order to adjust negative pressure from then on.By favourable mode, but keyer can be provided by a hairbrush that is contained in rocking arm shape displacement in the suction chamber.The latter here can be shifted on the gyroaxis rocking arm shape ground of suction chamber external parallel in hairbrush rotating shaft orientation around one, and this gyroaxis also can be simultaneously the rotating shaft that for example drives the motor of hairbrush by odontoid belt.If a carpet section is inhaled in the suction chamber in the process of suction operation, hairbrush is raised.After surpassing the starting threshold value, the hairbrush that plays the keyer effect here simultaneously impels delimits the device lifting, to adjust the negative pressure in the suction chamber.Itself also can be converted to the lifting force that is used to delimit device the negative pressure that acts in suction chamber.Therefore can constantly measure the negative pressure that in suction chamber, acts on.The threshold value that surpasses regulation causes opening the demarcation device.Embodiment is irrelevant therewith in principle, and the vertical movement of delimiting device is directly proportional with the negative pressure that records or is directly proportional with the deflection stroke of keyer.Can also stipulate that on suction function to the negative pressure piston, this negative pressure piston is fixedlyed connected with an actuating member that affacts the actuation gear on the demarcation device.Realize a kind of mechanical conceptual thus, it derives the upright position of the demarcation device of motion according to being present in the interior negative pressure of suction chamber.As an alternative mode or also as and the mode of aforesaid way combination, can also stipulate that establish rocking arm shape keyer in floor nozzle, it commutates when the forward travel of floor nozzle and setback conversion.Usually when the suction movement of advancing, carry out receiving of thick thing, and, then both utilized forward stroke also to utilize revesal to be the dedusting from the slit of precondition than high negative.According to the present invention by the rocking arm shape keyer that is located in the suction nozzle, opening when being released in the forward stroke that is used to receive thick thing automatically, that is to say, promote the demarcation device that moves both vertically, and when revesal, close the curtain that constitutes by the demarcation device that moves both vertically automatically.Xiang Guan keyer is designed to lever-like therewith, wherein, keyer deviate from ground that is back to the lever segments on the ground of wanting dust suction, the motion of device is delimited in control.Different with it, also can realize in the difference of forward travel between setback by the direction of rotation that detects presumable roller or other members that rotate.The actuation gear of having mentioned that affacts on the demarcation device can be lever system or flexible axle, advises also for the latter that wherein flexible axle is based on the link position of keyer lever segments, than the fixed bearing of the more close demarcation device in another position.For with the ground mating reaction, when suction port forward travel and the setback conversion switchable lever-like keyer, also suggestion, its rotating shaft moves both vertically for the balance deflection of crossing the border with can overcoming elastic force.Suggestion at last, the demarcation device of motion additionally can promote by a slide block that affacts in the actuation gear.Therefore user's effective pore that the demarcation device that moves both vertically by lifting might be discharged opens or is opened to the centre position constantly fully, in order that for example also can receive thick thing better.If although the negative pressure in the control suction chamber by the user is still too high, those devices of being introduced above then (in suction chamber deflectable keyer or depend on the control device of negative pressure) still in action so that further open effective pore.
