Definitions

  • the invention relates to a brush suction nozzle for a suction cleaning device with a brush which can be driven by a battery-powered electric motor, according to the features of the preamble of claim 1.
  • brush suction nozzles are used in connection with a suction cleaning device, which are equipped with a rotating, roller-shaped brush.
  • the rotatingly driven, roller-shaped brush is mounted in the brush suction nozzle in such a way that its bristle engages in the surface of the textile floor covering during the cleaning process, so that in addition to suction cleaning, dirt particles adhering to it are mechanically detached.
  • the rotating, generally roller-shaped brushes are driven in household appliances and in particular in commercial suction cleaning devices by an electric motor which is accommodated within the housing of the brush suction nozzle. Its power supply takes place generally via a detachable power cord, which is connected to a socket on the vacuum cleaner.
  • This connecting line which connects the drive motor of the brush suction nozzle with the mains-powered suction cleaning device, is particularly a hindrance in suction cleaning devices in which the brush suction nozzle can be connected by a longer suction line, for example suction pipe and suction hose with suction cleaning device, as is the case with larger household vacuum cleaners and in particular with commercial suction cleaning devices the case is.
  • the connecting line for the brush suction nozzle is guided along the suction hose and the suction pipe to the suction cleaning device, special brackets, for example retaining rings or the like, being provided which hold the connecting line for the brush suction nozzle on the suction lines.
  • the invention has for its object to provide a brush suction nozzle with the features of the generic term so that these disadvantages are avoided and a handy brush suction nozzle with a conveniently located center of gravity is created, in which the design of the actual suction nozzle is not affected by consideration of the installation of batteries and easy access to the batteries makes it easy to replace.
  • the battery or several batteries for the drive motor of the brush suction nozzle is arranged in a special holder on the guide handle of the brush suction nozzle
  • the actual suction nozzle in its construction can meet the usage requirements, for example with regard to its weight, the center of gravity and its external design can be adapted without restriction.
  • the arrangement of the holder on the guide stem also shifts the center of gravity of the device in a favorable manner, so that the additional weight of the batteries advantageously goes directly to the support rollers.
  • the holder itself can be produced cheaply and easily, for example as a pressed part, in such a way that the clamp connections required for holding the batteries and the electrical contacts can be provided directly in the holder itself.
  • the repeatedly rechargeable battery or several such batteries can be easily plugged into and removed from the holder provided according to the invention, the actual receptacle for the battery and a plug-in sleeve provided for plugging the holder onto the handle of the device being produced in one piece in a simple manner and without problems on the Guide handle can be attached.
  • the suction line connected to the suction cleaning device in a known manner does not experience any design change compared to known devices due to the arrangement of the battery holder according to the invention. It is advantageous to provide the holder on the outer surface of the part of the suction line designed as a guide stem, in the immediate vicinity of the connecting piece. As a result, the largest part of the weight of the battery and holder is guided to the support rollers by the shortest route, so that the device is not difficult to handle despite being operated by battery.
  • the brush suction nozzle 1 rests with the support rollers 2 on the textile surface 3 to be cleaned, in which the bristle 4 of the rotating brush 5 engages.
  • the brush roller 5 is driven by the electric motor 8 via the belt drive 9.
  • a connecting piece 11 is pivotally mounted about the axis 12. With the connecting piece 11, the guide stem 15 is connected as part of the suction line 16 by suction and non-positively, preferably via a plug connection.
  • the suction line 16 connects the brush suction nozzle 1 to the suction cleaning device, not shown.
  • the holder 17 for receiving one or more batteries 18 is attached on the handle 15 near the connecting piece 11, the holder 17 for receiving one or more batteries 18 is attached. It is provided with contacts, not shown, which are connected with the insertion of the battery 18 into the holder 17 with mating contacts fitted therein.
  • the battery 18 is electrically connected to the drive motor 8 via the connecting line 19.
  • a signal lamp is provided at a suitable point.
  • the battery to be charged is simply pulled out of the holder 17 and a charged battery is inserted in its place. Charging takes place in a known manner on a charger, not shown.
  • two or more holders for two or more batteries 18 can be arranged on the guide handle 15.
  • the bracket 17 has a receptacle 17 ', in which the battery is held by means of frictional engagement, for example by clamping means, not shown, and in which - also not shown - electrical contacts are provided.
  • the receptacle 17 is preferably arranged parallel and symmetrical to the axis 20 of the connecting piece 11 and designed in cross section approximately U-shaped, so that the operator can easily insert the battery or batteries from above into the insertion opening 17c of the pocket-like receptacle 17 'and again can pull out.
  • the holder which can be produced, for example, as an injection-molded part, has a plug-in sleeve 17 ', which is preferably made in one piece with the receptacle 17 and which can be attached to the outer circumference of the guide stem 15 by sliding it on or simply Clamping can be fixed. This design enables simple attachment and handling when inserting or removing the batteries.
  • the configuration makes it possible to easily remove the battery 18 from the contact part of the holder 17 after reaching the discharge limit and to replace it with a charged battery 18.
  • This can be taken from a storage part, which consists of one part with the holder 17 and is not shown in the drawing. These are sections of the holder in which the arrangement of live contacts or connecting lines is not necessary. They are only used to hold batteries that are not in use for reserve purposes.
  • One or more of the charged batteries 18 stored in holders 17 on the guide stem 15 can be switched off by a manual or automatically controlled circuit in the order in which they are discharged; At the same time, a charged battery can be switched on by the same control.
  • FIG. 2 shows a lateral arrangement of two batteries 18 in the holder 17, which is divided into assigned sections 17a and 17b.
  • the parallel sections 17a and 17b are also arranged symmetrically to the axis 20 of the connecting piece, preferably in such a way that they lie in a plane inclined to the vertical, which is laid through the axis 20.
  • the lateral attachment of the holder 17 shown in FIG. 2 has the advantage that when moving under furniture or the like with the brush suction nozzle, the holder 17 does not take up any additional space, so that work with the brush suction nozzle is not hindered, while at the same time being avoided, that the bracket 17 rests on the textile floor surface 3.
  • a switching device For switching on and off the pressed into the holder 17 battery 18, a switching device is installed within the holder 17, which switches the battery 18 when axially pressed in and by pressing the battery 18 again axially into the receptacle 17 'and 17a, 17b the battery can be switched off again.
  • Such a switch design offers the advantage that the switching elements can be matched in a simple manner to the relatively high direct current which draws a strong arc.
  • the guide handle 15 is part of the suction line 16;
  • the holder is arranged with a continuous, flexible hose and a guide separate therefrom either in a lower, less flexible part of the hose or on a frame part separate from the hose and the brush suction nozzle.
