Definitions

  • the invention relates to a battery-operated vacuum cleaner, comprising a suction container, a suction head, which is arranged on the suction material container, a blower device for generating a suction flow and at least one process air duct, which is fluidly connected to the blower device.
  • a vacuum cleaner is known, which has a battery device for supplying energy to the vacuum cleaner and for supplying energy to an external air valve device for cleaning a filter device.

  • the top of the nipple with battery means held thereon may be defined by the battery means, or the top is defined by a member of the nipple which is not battery means, and a retained battery means is flush with or reset to the top. It can be achieved in a simple manner that the battery device does not protrude or only slightly beyond an outline region of the nipple and in particular of the suction head.
  • the solution according to the invention makes it possible to achieve a space-saving and protected housing of the battery holder and the battery device on the suction head.
  • the battery device is detachably held on the battery holder.
  • the “residual vacuum cleaner” outside the suction head does not have to be modified or only slightly modified.
  • the blower device is positioned on the suction head.

  • the battery holder is arranged and designed such that, in the case of the battery device held on the battery holder, the battery device does not protrude beyond the top of the suction head. This results a space-saving accommodation. It reduces the risk of injury to an operator or prevents an operator from "hanging" on an inserted battery device. Furthermore, the battery device can be “sunk” and thus protected on the battery holder and thus in turn positioned on the suction head.
  • the arranged on the battery holder battery device is flush with a bow handle.
  • there is a flush transition to the bow handle As a result, for example, the risk of pinching a finger between the bow handle and the battery device is prevented or greatly reduced.
