Definitions

  • the invention relates to a portable suction device according to the preamble of claim 1.
  • the invention relates to a portable suction device with a suction channel opening into a suction nozzle and with a housing, a handle, a suction material container with an opening, a closure closing the opening, and a suction unit for generating a suction flow, which provides a suction vacuum applied to the suction nozzle, with a separation device which is able to split the suction flow sucked in via the suction nozzle into an exhaust air flow flowing out of the suction device and into suction material in the form of particles and / or fluid components, the separated particles or fluid components are collected in the suction material container and the suction material container can be emptied by opening the closure.
  • these devices also have a pull-off lip for pulling off liquids, the pull-off lip being arranged on the suction nozzle.
  • these devices are usually battery-operated and are held in the hand of a user while the user guides the pull-off lip along the surface to be vacuumed.
  • Portable devices of this type are among others from the EP 2 845 530 B1 known.
  • the known suction devices are used to suck up a liquid / air mixture. As in the case of the device mentioned, this can be done for sucking up liquid, for example from a flat surface such as a table top, window panes or tiles.
  • a pull-off lip arranged on the suction nozzle is provided in the generic devices for residue-free cleaning of the surfaces.
  • the suction material is stored in a suction material container and must therefore be separated from the suction flow from the air flow.
  • the known separation devices of the portable suction devices use baffle plates and air deflectors to separate the suction material from the suction flow.
  • Suction devices designed in this way have disadvantages. Sharp air deflections and baffle plates cause pressure losses that have a negative impact on the efficiency of the suction device. For the user, this manifests itself in a shorter device running time for a given usable capacity of the accumulator. In addition, such devices are correspondingly larger.
  • suction material Another requirement of the generic suction devices is to prevent the suction material from flowing back into the separation area.

In this way, an evasive volume is created around the outlet of the suction material guide, in which the suction material already stored in the suction material container is temporarily stored when the device is pivoted.
  • the suction devices In order to drain the suction material from the suction material container, the suction devices often have a closure designed as a small stopper on the suction material container. Furthermore, the suction material container is usually designed to be separately removable and also has a larger opening for better cleaning.
