  • the invention consists in a small vacuum cleaner of the type mentioned, in which an expanded or bulged interior is arranged in the lower part of the suction area and the suction opening above this interior in order to achieve the largest possible intake volume of a small vacuum cleaner, in particular to ensure that liquid that has been sucked in unintentionally leaks out, the bulge should be as large as possible.
  • the suction opening has an extension within the suction area, the extension extends hoaxally to the longitudinal axis of the housing, the inner opening of the extension is arranged above the bulged or enlarged interior and / or the inner opening in Direction of the bulged or expanded interior is arranged.
  • the small vacuum cleaner according to the invention has a liquid-tight wall on the side of the filter which projects into the inner cross-section of the housing of the suction area and partially closes its cross-section.
  • the filter on its suction side is covered with a cover cap a b - which can be removed from a rear filter support provided on the rear of the filter and which has an inlet opening for the inlet to the filter and is arranged above the interior.
  • the filter can be a dust-collecting foam rubber disc, which is held between the rear filter support and a front filter support, preferably attached to the cover flap, the filter being a can have air-permeable support structure extending at least over part of its surface.
  • the filter should extend essentially over the entire inner cross-section of the rear part of the suction area and between the wall of the cover cap and its surface on the suction side distribute the suction air flow over the entire filter surface, or have a filter prechamber.
  • the suction opening in relation to the longitudinal direction of the housing should be arranged at a height below the inlet opening or the opening to the filter.
  • the suction opening has an extension extending into the suction area, preferably up to the area near the wall or the cover cap.
  • the inner opening of the extension should advantageously be directed towards the interior, i.e. with at least one angular component transverse to the longitudinal axis of the housing.
  • the inlet opening to the filter also has an extension which extends into the suction area and is preferably arranged parallel to the inner surface of the upper wall section of the suction area and close to the inner surface thereof, and the inlet opening at the free end of the extension and the inlet opening is also aligned in the longitudinal direction of the housing.
  • a flap opening into the interior of the housing preferably consisting of a rubber flap, is provided on the inner opening and / or the suction opening.
  • the advantages of the invention are achieved with a combination of the following features, in which the extension for the inlet opening to the filter and for the extension for the suction opening in the axial direction of the housing at least partially overlap in the arrangement and the extension with its inlet opening above the opening on the outside Arranged at the end of the extension of the exit opening and the expanded or bulged interior is located below the opening.
  • the suction area can be removed as a must-like attachment from the rest of the housing and the cover cap is fastened separately in the interior thereof or is detachably fastened from the rear filter support.
  • the wall handle in the rear part of the housing is provided as an elongated opening formed in the longitudinal direction of the handle recess, the accumulators or batteries being arranged within the part of the housing spanned by a hand and the actuating switch with the exception side edge of this housing part is integrated.
  • the tril of the housing or the suction area is designed as a housing part which can be removed separately from the housing, so that the removal of coarse dirt and liquid which has not reached the filter can also be carried out without removing the entire snout-shaped suction area .
  • this removable housing part could also be designed in several volume sizes, for example on the one hand for normal use with little liquid and on the other hand with a particularly large volume, e.g. in the form of a pronounced liquid box or a liquid sack, which can also be plastic-bag-shaped.
  • the extensions to the inlet opening in the cover cap and possibly also the suction opening could then be provided as parts of the housing wall, the cover cap also being able to be fixed in the removable part of the suction region, so that when the snout-shaped housing part is removed of the suction area of the engine and handle part of the filter can be removed for cleaning.
  • a suction area 2 and an actuation area 3 are arranged within a housing 1, in which an electric motor 4 and a power supply unit 5, for example of accumulators or batteries 6, is also provided with an integrated charging unit, for which purpose Electrical connection can be built in, which lies in a coverable recess 13.
  • An operating control lamp 8 is also installed to indicate the charging and operating status.
  • the handle to be used for handling the small vacuum cleaner is designed in the form of an elongated handle recess 12, with the upper edge of which a switch lever 15 for an actuation switch 9 is integrated, which is to be actuated against a spring 10 about a pivot point 11.
  • the accumulators or batteries 6 are also located in the upper part of the handle.
  • the electric motor 4 is mounted within the housing 1 in a motor mounting 16 and carries on its axis oriented in the longitudinal direction of the housing 1 a suction fan wheel 14 which rotates within a fan wheel chamber 18, the fan wheel chamber 18 having a suction on the suction side. Admission forms. This also forms the construction for the rear filter support 21 of a filter 19, which e.g. can consist of a possibly grid-reinforced foam rubber plate and can be removed for cleaning when the housing 1 is open along its opening plane 20.
  • the removable attachment of the front housing part, which forms the suction area 2 can e.g. consist of conventional, not shown, snap devices.
  • the rear filter support 21 has a circumferentially arranged projection profile 22, to which a cover cap 23 which is attached to the suction side of the filter 19 can be fastened and which has a front filter support 24 in its interior for holding the filter 19 to the front, for example likewise in the form of a circumference Profiles (eg flange).
  • This cover cap 23 is at a distance from the front filter surface with its wall 26, so that a filter prechamber 25 is formed in order to pressurize the entire surface of the filter 19 with the sucked-in air stream.
