Description
Technical field
The present invention relates to a kind of dust catcher floor brush.
Background technology
Different dust catcher kind according to prior art can be divided into two kinds of different versions in principle:
Under the situation of so-called floor-type vacuum cleaner, in most of the cases be bearing in the shell on the roller and arrange motor, fan, filter unit and electronic installation.The suction pipe that normal length can telescopically be regulated at one end is connected by means of the shell of the suction hose of disturbing property and floor-type vacuum cleaner or fan and has and the floor brush of wanting clean Surface to contact at its other end.
Second version forms so-called hand held cleaner.Different with floor-type vacuum cleaner, this moment, suction pipe and Body case of cleaner were rigidly connected.And motor herein, fan, electric component and filter unit are positioned in the shell.The operating grip that this shell is settled in the extension that additionally has on the side relative with suction attachment at suction pipe.
The negative pressure that motor and fan is produced by means of floor brush is applied to be wanted on the clean Surface.This surface relates generally to hard, smooth floor covering surface as parquet floor, PVC, stone material or the like or relate to fabric face as for example carpet floor, soft cushion of furniture or analog.The different qualities on surface has proposed partly to go up opposite requirement to floor brush functional.
One of them requirement is, realizes the slip of softness as far as possible on each surface of dust catcher floor brush.This also is applicable to and is passing through edge, for example situation in the zone of threshold.In order to improve sliding properties, usually roller is arranged in the baseplate zone of dust catcher floor brush, wherein two preceding floor rollers are provided with the preceding rim identical distance with floor brush.When with this dust catcher floor brush vertically when a rim moves, then roller contacts this rim basically simultaneously; This causes cleaner suction nozzle suddenly to move on the rim, and this requires the undesirable strength of cost and especially cause producing undesirable click (Klappern) under hard surface condition.When by the depression in the surface, this click also takes place for the same reason, for example under the situation on relief designed fabric floor, be absorbed in the situation that the recess neutralization is come out again then simultaneously simultaneously from recess because this moment also usually occurs roller.
For fear of this known click clatter phenomenon, the someone advises roller is arranged with the interval different with preceding rim.But this design that has overcome above-mentioned defective effectively causes must having the relatively large zone that is used to settle roller between dust catcher pump orifice and preceding rim.This is disadvantageous for the positive suction properties of dust catcher, because for example current rim is when being docked on the rim plate, has very big interval between pump orifice and the rim plate.
Summary of the invention
Task of the present invention provides a kind of dust catcher floor brush, and it has overcome the click clatter problem at junction surface, has good positive suction properties simultaneously.
This task solves with a kind of dust catcher floor brush.This dust catcher floor brush comprises the suction channel that opens wide to pump orifice, and at the preceding rim that transversely extends and at least one the first preceding floor roller and the second preceding floor roller of direction of primary motion, they have different intervals with respect to preceding rim.According to the present invention, the first preceding floor roller is arranged in the pump orifice front, and the second preceding floor roller is arranged in the pump orifice back.
The present invention constructs on the basis of this dust catcher floor brush, and promptly the first floor roller is arranged in after the pump orifice with the second floor roller before being arranged in pump orifice.Make the design that this is favourable like this, be about to the floor roller and be provided with different intervals, combine with the layout in the saving space of roller with the preceding rim of floor brush.The saving in this space especially relates to being used to before pump orifice and settles the desired zone of roller.Because second roller is arranged in after the pump orifice, so this zone that is positioned at before the pump orifice can be constructed very for a short time.
The invention still further relates to other favourable form of implementation, provide hereinafter.
Regulation advantageously, pump orifice has in the zone of the first floor roller than big and interval preceding rim in the zone of the second floor roller.Bigger interval with preceding rim in the zone of first roller is used to settle first roller.Owing in the zone of second roller, do not need this bigger interval, so pump orifice can be near preceding rim, with the positive suction properties that provides in the second roller zone.
For example this can realize thus, and promptly for different intervals is provided, pump orifice has sweep.
Be contemplated that equally for different intervals is provided, pump orifice has groove, in this groove, arrange the first floor roller.
The present invention improves in particularly advantageous mode, promptly arranges other floor roller after the first and second floor rollers, and they have identical distance with respect to preceding rim.Especially for the back roller advantageously with them with identical distance with respect to preceding rim setting, because this can improve the sliding properties of dust catcher floor brush.Because the back roller is constructed greater than preceding roller usually, therefore preceding roller always slips over the out-of-flatness part in the floor at an easy rate.
Description of drawings
The present invention exemplarily is described according to a particularly preferred form of implementation referring now to accompanying drawing.
Shown in it:
Fig. 1 is according to a dust catcher floor brush of the present invention perspective view seeing of side from it;
Fig. 2 is a perspective view of seeing from its downside according to dust catcher floor brush of the present invention; With
