  • the body of the device and the suction material container are connected to each other via a bayonet lock.
  • the suction material container can be detached from the device body via a rotary movement of the suction material container relative to the device body. Due to the size and weight of the suction material container and the body of the device, such a removal of the suction material container is disadvantageous from the point of view of operator ergonomics.
  • the invention therefore addresses the problem of providing a hand-held cyclone vacuum cleaner in which the removal and operation of the suction material container are simple.
  • the advantages that can be achieved with the invention are, in addition to simple handling of the suction material container of the vacuum cleaner, that removal and emptying can be carried out using a single operating element. This enables the user to carry out all relevant handling steps via an intuitively operated rotary element.
  • the rotatable operating element can be easily integrated into the design of the vacuum cleaner, with creative freedom being achieved.
  • the invention relates to a hand-held cyclone vacuum cleaner, having an appliance body which has a drive unit which is designed to generate a suction air flow, a suction material container for receiving suction material, which is connected to the device body, a control element which is located at one end of the suction material container is arranged, which is opposite the end of the suction material container on which the device body is arranged, wherein the control element moves from a first position to a second position and is reversely rotatable, wherein the device body is inseparably connected to the suction material container in the first position and the device body is separably connected to the suction material container in the second position.

  • removably connected is to be understood as meaning that the suction material container and the device body can be separated by pulling them apart.
  • the suction material container In an operational working position, the suction material container is located at a rear or rear end of the vacuum cleaner, which means that it is closer to the user's hand and further away from the surface to be vacuumed than the device body. As a result, the control element is easy to handle.
  • the device body has a base plate and a connecting piece with a locking cam that extends away from the base plate, and the suction material container has a prefilter with a locking geometry that is designed in such a way that it holds the locking cam in the first position of the operating element and releases in the second position of the control element, so that the device body is permanently connected to the suction material container in the first position of the control element and is connected to the suction material container in a removable manner in the second position.
  • the suction material container has a housing and a pre-filter with a sleeve-like part which is arranged in the housing, one end of the housing and one end of a wall of the device body extending away from the base plate having a complementary contour and the sleeve-like part Part can be placed on the nozzle.
  • the suction material container and the device body can be connected to one another.
  • the connecting piece preferably has a plurality of locking cams and the pre-filter has a plurality of locking geometries, each of which is designed and designed to accommodate a locking cam, each locking geometry having a slot which is open in the direction of the base plate when the suction material container is placed on the device body, and each having a locking portion extending away from the respective slot, closed towards the base plate and extending angularly away from the respective slot in the direction opposite to the base plate.

  • Each slot of each locking geometry is preferably designed to allow a locking cam of the connecting piece to be inserted at least partially into the sleeve-like part of the pre-filter when the suction material container is placed on the device body. As a result, the suction material container can be placed on the device body without additional force being applied. The way for the placement is limited by a stop of the respective slot.
  • Each locking geometry preferably has a geometry such that the suction material container can be placed in a predetermined position. This encodes the system.
  • the locking cams and the locking geometries are preferably designed in such a way that the locking cams are arranged in the respectively assigned locking part when the operating element is in the first position and that the locking cams are arranged in the respectively assigned slot when the operating element is in the second position located.
  • the latching cams are preferably designed in such a way that they are guided into the slots or locking parts by rotating the operating element when the operating element is rotated from the first to the second position and vice versa.
  • the body of the device and the suction material container cannot be separated in the first position by being pulled apart or pulled away from one another, and can be separated in the second position by being pulled apart.
  • the slits are arranged in a helical shape, as a result of which the suction material container is lifted off the device body slightly when the operating element is moved into a second position.
  • the suction material container preferably has the housing, the pre-filter arranged in the housing, a central filter arranged in the pre-filter and a flap which is arranged at the end of the suction material container on which the device body is arranged.
  • the operating element can also be rotated into a third, fourth and/or fifth position and vice versa, with the flap being openable in the third position, the central filter being removable from the pre-filter and thus the housing in the fourth position, and the pre-filter being in the fifth position can be removed from the housing.

  • the pre-filter can preferably only be removed from the housing in the fifth position; that is, it is non-removable from the housing in any position other than the fifth position.
  • the suction material container is preferably designed in such a way that the user touches unpolluted areas of the central filter and the pre-filter in order to remove the central filter and/or the pre-filter. This is achieved by the fact that the area of the central and pre-filter that the user has to grip for removal is preferably not arranged in a separation space in which particles from a suction flow are separated during operation. Ie, her are not located in a suction material collection chamber in which the suction material is collected during operation.
  • the latching cam of the connecting piece is preferably arranged adjacent to a stop of the locking geometry, so that when the operating element is rotated from the first position into the second position, further rotation of the operating element beyond the second position into the third position is prevented, as long as the suction material container is placed on the device body. This ensures that the flap can only be opened when the device body is separated from the suction material container.
  • the flap has a flap latching cam, which engages in the locking geometry of the prefilter when the control element is in the second position, and which is designed in such a way that when the suction material container is separated from the device body and the control element is rotated into the third Position is above a recess in the locking geometry of the pre-filter, so that the flap can be opened. This ensures that the flap is tightly connected to the pre-filter when the vacuum cleaner is in operation.
  • the flap can preferably be opened by pivoting or flaps.
  • the flap preferably has a plurality of flap latching cams, each of which engages in one of the plurality of locking geometries of the prefilter when the operating element is in the second position.
  • the flap locking cams are preferably distributed evenly around the circumference of the flap.
  • the flap locking cams are preferably arranged centrally on the flap. Due to the fact that a locking of the flap is designed centrally and distributed around the circumference, a further optimized pressing of the flap onto the pre-filter and the housing is provided.
  • the suction material container preferably also has a spring which is designed to pivot the flap away from the housing and the pre-filter when the operating element is in the third position. This automates opening of the flap for emptying the suction material container.
  • the spring is preferably connected to the pre-filter and the flap.
  • the spring is preferably connected to the pre-filter via a bellows, which also supports a movement of an exhaust air duct formed by means of a separating plate in the direction out of the suction material container when the flap is opened, the separating plate separating the exhaust air duct from the suction material collecting chamber in a radial direction.
  • the suction material container also has a latching hook, which is arranged on the pre-filter, which holds the central filter in the pre-filter and which is designed in such a way that it is force-free in an operating state and has a spring travel after turning the control element into the fourth position is released, so that the central filter can be removed from the pre-filter.
  • a latching hook which is arranged on the pre-filter, which holds the central filter in the pre-filter and which is designed in such a way that it is force-free in an operating state and has a spring travel after turning the control element into the fourth position is released, so that the central filter can be removed from the pre-filter.
  • the pre-filter preferably has at least three cross ribs and the operating element has a centering ring with grooves in which the cross ribs run.
  • the grooves are preferably designed in such a way that they each have an opening in the fifth position, so that the pre-filter and the operating element can be removed perpendicular to the axis of rotation of the operating element.
  • the grooves are preferably designed in such a way that when the pre-filter moves between the third and fifth position, the pre-filter is lifted off the central filter. This ensures optimal access to all components in the event of service.
  • the crossed ribs are preferably distributed over the circumference of the pre-filter. They serve as guide elements when the operating element is rotated.
  • the pre-filter has at least three pins and the operating element has a centering ring with grooves in which the pins run. If the central filter is arranged in the fifth position of the operating element in the pre-filter, it can be removed together with this and the operating element in the fifth position. However, the central filter can also have already been removed from the pre-filter when the operating element is in the fourth position. In the fifth position, it is irrelevant whether the central filter is in the pre-filter or not.
  • the suction material container is preferably designed in such a way that the operating element and the pre-filter can only be partially removed in the fifth position and can only be completely removed after turning the operating element into a sixth position, which lies between the fourth and fifth position, and then turning it again into the fifth position are designed to be removable from the housing.
  • This is advantageous because the user can then only deliberately remove the control element and the pre-filter by deliberately rotating the control element from the fifth position to the sixth position in the direction of the fourth position and then into the fifth position. This ensures that the user does not suddenly hold the pre-filter in his hand while the housing falls through the separation from the pre-filter.
  • the expression “partially removable” means that the connection between the pre-filter and the housing is only partially and incompletely detached.
  • the cross ribs are preferably encoded.
  • the cross ribs are offset by a predetermined amount about the circumference of the prefilter with the exception of one cross rib which is offset by a different amount than the predetermined amount.
  • two cross ribs are arranged offset by 120°, for example, over the circumference of the prefilter, while the third cross rib is arranged offset by a value other than 120°.
  • the control element preferably has latching points and entry guides which are correspondingly encoded. That is, they are preferably offset by a predetermined value distributed over the circumference of the operating element with the exception of a detent point and an entry guide, which are arranged offset by a value other than the predetermined value.
  • the centering ring has latching points which can be overcome by the cross ribs when turning, in order to reach the next position of the first, second, third, fourth and fifth position during turning. This ensures clean positioning in the respective position.
  • the operating element is preferably designed such that it is rotated from the first to the second position by 20-25°, that it is rotated by 42-45° from the first to the third position, that it is rotated from the first to the fourth position is rotated 77-80° and that it is rotated 88-90° from the first to the fifth position.

This ensures that when the pre-filter and/or the central filter is removed, the suction material collection chamber is also emptied. In addition, this ensures that the central filter cannot be removed as long as the suction material container is still in the device body or the suction material container has not yet been emptied. This prevents dust or dirt particles from getting into the intake area of the fan.
