Abstract
The present invention provides a floor cleaner head used for vacuum cleaner. Said floor cleaner head comprises a suction head (1), a slippage soleplate (2) mounted at the suction head (1), and a suction pipeline connection element (5) which is inserted to a suction channel (4) of the suction head (1) and is then capable of rotating surrounding a level axes (6) of a hinge joint. A roll wheel module (7) is arranged at the back end of the suction channel (4) and a vertically adjustable carrier (8) is provided at inner side of the suction head (1). A seal strip (9) is connected to the carrier (8) and is mounted in front of the slippage soleplate (2). In the back of the slippage soleplate (2), the carrier (8) has a working surface (10) which is effective to smooth floors, wherein the working surface (10) extends, between the slippage soleplate (2) and the roll wheel module (7), backward to both sides of the roll wheel module (7). With a vertical adjustment of the carrier (8), the front seal strip (9) and the back working surface (10) can together extend to a certain range at the bottom surface of the suction head (1). Within said range, when a smooth floor is cleaned, the roll wheel module (7) doesn't contact the floor, and the suction head (1) is supported at the working surface (10) of the carrier (8) and the seal strip (9) locating at the front.
Description
Technical field
The present invention relates to be used for the floor cleaning head of vacuum cleaner, it comprises:
Have a dust collecter at the sliding floor of bottom side, described dust collecter has the suction nozzle with battery unit in the horizontal expansion of operative orientation, and the suction channel that ends at suction nozzle with battery unit;
A suction channel Connection Element, it inserts in the suction channel, so this pipe connecting element can rotate around the horizontal axis of articulated joint;
Be positioned at the roll assembly of suction channel rear end;
Be positioned at the carrier dust collecter inboard, that can vertically adjust.
Along the vacuum cleaning direction, the sealing tape is placed in the place ahead of the sliding floor of carrier.In addition, along the vacuum cleaning direction, carrier is provided with working surface, and it is positioned at the rear of sliding floor, can act on the smooth floor, for example can be set to wipe surfaces.The sealing tape that is positioned at the place ahead can extend a bottom side that coexist dust collecter with the working surface that is positioned at the rear.
Background technology
From file DE-29900713 U1, can learn floor cleaning head with above-mentioned technical characterictic.In the roll assembly that constitutes by running roller, running roller is arranged on the outside of suction channel, and is spaced from each other, and be positioned at the rear of dust collecter with dust collecter.The axis of articulated joint and the axis coaxle of roll assembly, perhaps the position is leaned on very closely at least.The active force vertically that the suction channel that connects by Connection Element produces in the reciprocal vacuum cleaning motion process in front and back is absorbed by roll assembly.Dust collecter is hinged on the floor surface movably, so that vacuum cleaning under the effect of the vacuum pressure that produces at himself gravity and suction nozzle with battery unit place.So floor cleaning head can be under smaller thrust that applies and pulling force effect, front-rear reciprocation movement.On the contrary, when vacuum cleaning, be difficult to finish transverse movement.When to the vacuum cleaning of level and smooth floor, this is outstanding especially shortcoming, is infeasible because adopt rag to clean.The floor cleaning head that is not easy to transverse movement also hinders carries out edge and corner vacuum cleaning.
Summary of the invention
The objective of the invention is to improve operation and the key property of floor cleaning head on smooth floor.
The technical scheme of theme of the present invention and realization above-mentioned purpose realizes that by a floor cleaning head that is used for vacuum cleaner it comprises:
A dust collecter that has at the sliding floor of bottom side, it has the suction nozzle with battery unit in the horizontal expansion of operative orientation, and the suction channel that ends at suction nozzle with battery unit;
A suction channel Connection Element, it inserts in the suction channel, so this pipe connecting element can rotate around the horizontal axis of articulated joint;
Be positioned at the roll assembly of suction channel rear end;
Be positioned at the carrier of dust collecter inboard;
Wherein along the vacuum cleaning direction, the place ahead at sliding floor, on carrier, be connected with the sealing tape, along the vacuum cleaning direction, at the rear side of sliding floor, carrier has working surface, and described working surface can be operated on smooth floor effectively, it extends between sliding floor and roll assembly, and extends rearward to the both sides of roll assembly; If to the vacuum cleaning of smooth floor the time, carrier is vertically adjusted, make it arrive the point that roll assembly does not contact with the floor, the sealing tape that is positioned at the place ahead can extend in the bottom side of dust collecter together with the working surface that is positioned at the rear, so dust collecter leans against the working surface of carrier and is positioned on the sealing tape in the place ahead.
By switch, for example, be arranged on the pedal switch at dust collecter top, can between " carrier lifting " and " carrier decline " two function setting, adjust carrier.Be provided with in described " carrier lifting ", floor cleaning head can be used to floor and the carpet of laying carpet are carried out vacuum cleaning.At this moment, dust collecter is seated on the roll assembly, only under the negative pressure of vacuum effect that self gravitation and suction nozzle with battery unit apply, dust collecter is hinged on the floor surface movably, therefore by applying less thrust or pulling force floor cleaning head is passed through on the floor.During for the vacuum cleaning of smooth floor, for example, stone floor, parquet floor or plastic floor, along with carrier is vertically adjusted, the working surface of carrier extends under the function setting of " carrier decline " with the sealing tape that is positioned at the place ahead.Under described " carrier decline " function setting, roll assembly is plate non-contiguously.At this POF, floor cleaning head is seated in working surface and is positioned on the sealing tape in the place ahead.These elements can be guided on floor surface, therefore can carry out vertical or horizontal motion, particularly, have the motion that can finish when using rag usually.According to working surface provided by the invention, can apply active force in a satisfactory manner for the clean, smooth floor.In the process of carrying out the vacuum cleaning campaign, the active force that applies by dust collecter is absorbed by working surface basically, therefore has the working surface that can obtain to have good mechanical properties on the floor covering.In addition, working surface stretches out in the bottom side, and the sealing tape sealing that is positioned at the place ahead is positioned at the vacuum cleaning zone of sliding floor below, therefore can obtain enough vacuum cleaning power.
The sealing tape that is positioned at the place ahead preferably is made of the bristle band.Do not get rid of the structure type that adopts other, for example the tape that constitutes by rubber or foamed material yet.
Have multiple mode and can constitute the working surface that acts on the smooth floor, the working surface of employing can be selected according to the floor cleaning head that is suitable for.In one embodiment, the working surface of carrier has brushing cluster.Settle a row or multi-row brushing cluster around the periphery of carrier at last.Comprise and adopt the application of hard bristle expansion floor cleaning head to dirty room, for example basement or garage.The working surface of carrier also can be provided with the soft covering that is suitable for the smooth floor of wiping, for example, is used for mainly being provided with the covering of the family on smooth floor.In another embodiment, the cloth that can remove is housed on working surface.This cloth can be that do or wet floor cloth.Adopt dried cloth to have reasonable dust abstraction function, for example adopt the textile cloth of microfibre, above-mentioned structure all belongs to design of the present invention.
Below in conjunction with accompanying drawing, describe one embodiment of the present of invention in detail.
