In addition describe in detail in application for patent noted earlier: how brush roll 16 is driven by electro-motor 52.

For supply electro-motor 52 electric energy, floor cleaning device 10 comprises the rechargeable battery 56 of two battery forms (such as lithium-ions battery form).Battery 56 remains in handle rod shell lower component 30 by keeper 46, and therefore remains on handle bar 20.Battery 56 is indulged plane about the center of floor cleaning device 10 be arranged in (Fig. 2) on floor cleaning device 10 with being mutually symmetrical.

For keeping battery 56, keeper 46 has first section 58.This first section 58 is arranged in the top of cleaning head 12, and is accommodation place 60 that each battery 56 defines pit shaft shape, and this accommodation place 60 is disposed generally on the height of brush roll 16 in the longitudinal direction of floor cleaning device 10.Each accommodation place 60 have on the side of its cleaning head 12 dorsad for battery 56, the upside that can touch in a simple manner decoupled for user introduces opening 62.Battery 56 can load in accommodation place 60 without the need to instrument on person ground easy to use by introducing opening 62.At this, battery 56 and the clamping mechanism 64 phase screens be arranged in accommodation place 60, and be fastened in accommodation place 60.

Battery 56 stretches out in accommodation place 60 with the side of cleaning head 12 dorsad.After screens is unclamped, battery 56 can be taken out from accommodation 60 without the need to instrument by user thus in a simple manner decoupled, such as, battery 56 is delivered to outside and unshowned charging station in the accompanying drawings, to charge.

In gap 60, be furnished with contact element 66 in addition, utilize contact element 66 battery 56 electrical contact can be connected, to obtain electric energy from battery 56.Contact element 66 is effectively connected with the electrical mechanisms 68 of floor cleaning device 10, and this contact element 66 is arranged in the accommodation 72 that formed by another section 70 of keeper 46.

The longitudinal direction of portion's section 70 and floor cleaning device 10 is arranged between first section 58 of keeper 46 and second section 74 relatively, and this second section 74 forms above-mentioned the second half clamshells 44 of electro-motor 52 and suction unit 54 housing 42 used.Portion's section 70 defines the 3rd section of keeper 46 above cleaning head 12.Therefore, keeper 46 idiomorphism is formed in the space 76(Fig. 5 between container assemblies 34 and cleaning head 12) stretch out towards the direction in floor cleaning device 10 front 78, specifically to be arranged in the 3rd section 70 below cleaning head 12 and first section 58 is stretched out.

Accommodation place 72 of the 3rd section 70 has the introducing opening 80 of upside.When assembling floor cleaning device 10, according to plain mode, electrical mechanisms 68 can be introduced by introducing opening 80.Accommodation place 72 is closed, to protect electrical mechanisms 68 from ectocine by lid 82 dust and water protection.

Electrical mechanisms 68 is effectively connected with electro-motor 52 equally.The mode that two batteries 56 discharge in the operation of floor cleaning device 10 can be controlled, to provide electric energy to electro-motor 52 by this electrical mechanisms 68.This point such as can be carried out as follows, that is: first make a battery 56 discharge, and after this battery discharges completely, then make the second battery 56 discharge.

By battery 56 being used for power to electro-motor 52, can cancel in floor cleaning device 10 required in other situations, be energy supply and the cable that with it floor cleaning device 10 will be connected on supply network.Doing advantage on the one hand is like this, floor cleaning device 10 is more promptly carried out to use than traditional floor cleaning device and prepared, this is because will not be connected with supply network by cable when user debugs.On the other hand, the range of movement of floor cleaning device 10 expands to some extent compared with traditional floor cleaning device, because can cancel the cable provided constraints having and limit length.

Another advantage of floor cleaning device 10 based on keeper 46 previous constructions scheme and obtain, and here particularly to explain with reference to Fig. 3 and 4.

As already mentioned, pivot axis 18 is moved towards by the Central places of housing 42.Thus, pivot axis is surrounded at one side of something by second section 74 forming half clamshell 44.First section 58 has a spacing relative to second section 74.Therefore, battery 56 and pivot axis 18 have a spacing.Particularly battery 56 is arranged in before pivot axis 18 relatively with the longitudinal direction of floor cleaning device 10.

As carpopodium bar 20 by user when debugging floor cleaning device 10 around pivot axis 18 pivotable, and transfer in run location, so container assemblies 34 reaches after pivot axis 18 relatively with the longitudinal direction of floor cleaning device 10.Cause like this: particularly container assemblies 34 comprises the clean liquid 37 that is accommodated therein and contaminated liquid 39 creates the first tilting moment acting on handle bar 20.

On traditional floor cleaning device, user must react on this tilting moment at handgrip 22 place, continues the direction pivotable towards earth's surface to prevent handle bar 20 around pivot axis 18.This point is felt it is interference when traditional floor cleaning device works by user.

Here according in floor cleaning device 10 of the present invention, battery 56 produces the second tilting moment.This second tilting moment is delivered to by keeper 46 in the handle rod shell lower component 30 that is connected with keeper 46, and is therefore delivered on handle bar 20.Thus, keeper 46 forms the lever arm acted on handle bar 20.The second tilting moment produced by battery 56 reacts on particularly by the first tilting moment that container assemblies 34 produces, because battery 56 is arranged in before pivot axis 18 on the run location of handle bar 20.

For user, can feel the effect of the second tilting moment as follows, that is: user declines for handle bar 20 being remained on the load that run location must apply on handgrip 22.This point feels comfortable for user when utilizing floor cleaning device 10 to work, thus the feature of this floor cleaning device is very high handling comfort.In the ideal case, if the first tilting moment and the second tilting moment are offset just, then the load on handgrip 22 disappears even completely.

Battery 56 remains on handle bar 20 towards on the bottom of cleaning head 12 by keeper 46, and keeper 46 is erect roughly at a right angle from this bottom.Therefore, though battery and floor cleaning device 10 longitudinally relatively-at handle bar 20 horizontal alignment, when being namely in the extension of cleaning head 12, be still arranged in before pivot axis 18.Therefore, by producing the second tilting moment in the very large angular range of battery 56 different run location between cleaning head 12 from handle bar 20 in its run location.This point means, handle bar 20 can occupy run locations different in angle of pivot different in a large number relative to cleaning head 12, and on these run locations, the second tilting moment reduces the impact that handgrip 22 place is conducive to handling comfort.

First section 58 and the 3rd section 70 form a common rest element 84 on its bottom side towards cleaning head 12.Rest element 84 can be resisted against on the cover plate 86 of cleaning head 12 in the resting position of handle bar 20 and particularly lie on the cover plate 86 of cleaning head 12 (Fig. 1 to 3).Thus, in the resting position of handle bar 20, the weight of battery 56 to be drawn out on cleaning head 12 and to reduce keeper 46 application of loads.
