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 having a handle, a suction material container with an opening and a closure closing the opening and a suction unit to generate a suction flow that provides a suction vacuum applied to the suction nozzle, and with a separation device that 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.
  • 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. To see the residue-free cleaning of the surfaces, a pull-off lip arranged on the suction nozzle is provided in the generic devices.
  • More portable devices of this type that have similar solutions as the EP 2 845 530 B1 for the closure are from the EP 2 837 316 A2 , the GB 2 437 702 A , the CN 203 898196 U and the WO 2015/007327 A1 known.
  • the US 6 687 952 B1 shows a suction nozzle with wet / dry suction function with a comparable closure.
  • the generic devices often have a closure designed as a small stopper on the suction material container for emptying the suction material and a larger opening or division of the suction material container for better cleaning.
  • the larger opening or division of the suction material container is also provided for reasons of ease of installation, in order to enable internal parts such as the suction material guide to be installed.
  • the US 6,216,314 B1 a suction device with a sealing plug with an opening tab that goes over a retaining tab is secured to the suction device.
  • the US 6,347,428 B1 describes, however, a screwed cap.
  • the closure is formed from at least a first closure element and a second closure element, such that the first closure element is set up to seal the opening of the suction material container against the escape of suction material and the second closure element is arranged outside the first closure element.
  • the design of the closure with two elements enables functional advantages with a high degree of design freedom at the same time.
  • a secure seal is thus realized by a round contour of a sealing surface of the first closure element, but the outer second closure element is set up to continue an outer contour of the housing of the suction device, that is to say the suction device geometry.
  • the closure can be designed structurally in such a way that excessive use of material and accumulations of mass are avoided. This in turn has a positive effect on costs. Production-related sink marks can also be avoided.
  • the closure that is to say the first and second closure elements, can be designed in one piece.
  • the second closure element is spaced apart from the first closure element.
  • the second closure element can be arranged around the first closure element in the manner of a bell.
  • the opening of the suction material container advantageously has a round cross section.
  • the first closure element then forms a corresponding round cross section that seals the opening.
  • the second closure element is set up to continue the outer contour of the housing of the suction device.
  • the second closure element of the closure can form a three-dimensional section which defines part of the outer contour, for example a cap-shaped element.
  • the shape of the suction device is designed such that the suction device extends into a handle of the suction device on the end section opposite the suction nozzle.
  • At least part of the suction material container is arranged in the handle and the closure is arranged in the handle. Since the second closure element can be designed independently of the first closure element, the closure advantageously forms part of the handle. Because the suction material container extends to the distal end of the handle, a particularly compact design of the suction device is achieved. In this way, the installation space is fully utilized.
  • the closure is arranged at the distal end of the handle and advantageously forms the distal end of the handle.
  • the second closure element is preferably formed from a soft material.
  • This can be a soft plastic or a rubber-elastic material, for example. In this way, good haptics are achieved, so that the user can easily grasp the closure and open it.
  • the lock also provides protection against impacts and scratches if the device accidentally hits an object or object while in use, or if the surface to be cleaned is touched during the cleaning process or the suction device even falls down.
  • the closure can have one or more functional elements which interact with corresponding counterparts in the area of the opening of the suction material container.
  • the functional elements can preferably be arranged between the first closure element and the second closure element.
  • some of the functional elements can be designed as ribs. These are set up to support the second closure element with respect to the first closure element.
  • the functional elements can also be designed as connecting elements, in particular in connection with corresponding counterparts in the area of the opening of the suction material container.
  • these can be screw or bayonet connection elements.
  • the first closure element is preferably made of a soft material and is configured to close the opening of the suction material container in a sealing manner with respect to the surroundings.
  • a separate sealing element can also be arranged on the first closure element in order to seal the opening.
  • the sealing element can be designed as a separate part or it can also be injection-molded onto the first closure element.
  • Another advantage is that the forces acting on the outer wall are decoupled from the inner, denser wall, so that undesired leakage can be avoided.

  • the lower part of the housing 6, as a handle shell 70, forms part of the handle 48, which is made in several parts.
  • the grip shell 70 in turn simultaneously forms a lower boundary of the suction material container 8.
  • the suction and separation areas are each received by a front part of the housing 6, which also forms the receptacle for the suction nozzle 4.
  • the shape of the suction device 2 is designed in such a way that the suction device 2 is accommodated by two parking areas when it is placed on a flat parking surface 72.
  • the first storage area is formed by the lower part of the handle shell 70, on which two feet are provided as storage elements 74.
  • the two storage elements 74 are arranged at a distance from a longitudinal axis of the suction device 2 on both sides.
  • the second storage area forms part of the lock 42.
  • the two storage elements 74 allow the suction device 2 to be placed on the flat storage surface 72 in a stable manner.
  • the parking areas are arranged on the suction device 2 in such a way that the suction nozzle 4 and in particular the pull-off lip 5 are spaced apart from the flat parking surface 72.
  • Both the outer area of the closure 42 and the storage elements 74 designed as feet are made from a soft material, in particular from a rubber-like material. In this way, in addition to a stable and surface-friendly position of the suction device 2 when the suction device 2 is switched off, damage when using the suction device 2, if the suction device 2 does not come into contact with the surface to be cleaned or the surfaces around it, is avoided.
