Definitions

  • the present invention relates to a cleaning device according to claim 1 and to a method of manufacturing a cleaning device according to claim 15.
  • Cleaning devices such as mops, brooms, brushes or the like are well-known in the art. In places such as bathrooms or kitchens it is furthermore often desired to apply moisture or even detergents for better removal of pollutants to the cleaning device.
  • cleaning pads can be attached to certain cleaning devices, and wherein the moisture or detergent is applied to the surface or object to be cleaned via the cleaning pads. After cleaning the soiled cleaning pad is disposed and replaced by a new cleaning pad.
  • US 2019/0387948 A1 discloses a cleaning tool comprising a handle to be gripped by a user and a body that is attached to the handle and to which a web is removably attachable.
  • the body furthermore comprises a pushing unit that enables the user to remove the soiled web.
  • the disadvantages associated with such a cleaning tool are the fact that a user must bend down to the body in order to actuate the pushing unit. Thereby the user comes into proximity with the soiled web which can be unpleasant and above all unhygienically for the user.
  • a cleaning device which cleaning device comprises a handle extending along a longitudinal axis and a cleaning head.
  • the cleaning head is in connection with the handle.
  • the cleaning head is pivotally in connection with the handle.
  • the cleaning head is configured such that a cleaning pad is detachably fastenable to the cleaning head.
  • the cleaning device further comprises a detaching device, wherein the detaching device is movably mounted to the handle and is configured to be moved along the longitudinal axis with respect to the handle from a cleaning position into a detaching position.
  • the detaching device is movably mounted to the handle and is configured to be moved along the longitudinal axis with respect to the handle from a cleaning position into a detaching position.
  • a cleaning pad being fastened to the cleaning head remains fastened to the cleaning head.
  • a cleaning pad being fastened to the cleaning head is detached from the cleaning head.
  • an ejection direction and a retraction direction can be defined. Both directions, i.e. the ejection direction and the retraction direction run parallel to the longitudinal axis. However, the ejection direction and the retraction direction run opposite to one another.
  • the ejection direction is understood herein as a direction extending from a proximal end of the handle towards a distal end of the handle. Consequently, the retraction direction is understood as a direction extending from the distal end of the handle towards the proximal end of the handle.
  • the detaching device is preferably movable along the ejection direction as well as along the retraction direction.
  • the detaching device is movable along the ejection direction in the event that the detaching device is transferred from the cleaning position into the detaching position, and that the detaching device is movable along the retraction direction in the event that the detaching device is transferred from the detaching position into the cleaning position. That is, the detaching device is preferably configured to be moved along the longitudinal axis with respect to the handle from the cleaning position into the detaching position as well as from the detaching position into the cleaning position. It should be noted that statements made herein regarding a movement with respect to the longitudinal axis or along the longitudinal axis preferably correspond to a movement with respect to or along the ejection direction as well as the retraction direction.
  • the cleaning device comprises a detaching device that is mounted to the handle, wherein an actuation of the detaching device can be carried out in the region of the handle. Consequently, if a user wishes to replace a soiled cleaning pad he or she can simply actuate the detaching device while remaining in his or her position. In other words, the user does not have to bend himself down towards the cleaning pad.
  • the cleaning device therefore enables an ergonomic and at the same time also hygienic handling.
  • the handle preferably corresponds to an elongate bar which is grippable by a user.
  • the movement of the detaching device along the longitudinal axis of the handle preferably corresponds to an axial displacement of the detaching device with respect to the handle.
  • the detaching device preferably comprises a rod extending along the longitudinal axis, wherein an ejector element is provided in the region of a distal end of the rod, and wherein the ejector element is configured to press against a cleaning pad being fastened to the cleaning head in order to detach the cleaning pad from the cleaning head when the detaching device is in the detaching position.
  • the ejector element In the detaching position the ejector element preferably at least partially protrudes from the cleaning head when seen along the ejection direction, i.e. the ejector element preferably at least partially protrudes from an underside of the cleaning device and towards a floor when seen in a state of use.
  • the user In order to attach a new cleaning pad to the cleaning device the user preferably transfers the detaching device from its detaching position into its cleaning position by moving the detaching device along the longitudinal axis, in particular along the retraction direction, whereby the ejector element is moved relative to the handle from its protruding position back into a non-protruding position, i.e. into the cleaning position.
  • the ejector element and the rod can be provided as a single piece element. Alternatively, it is likewise conceivable that the ejector element and the rod are configured separately from one another. In the latter case it is furthermore conceivable to removably or permanently fasten the ejector element to the rod. If the ejector element is configured removably it can be replaced by a new ejector element, for example if an ejector element is broken.
  • the rod and the ejector element are preferably mounted at least partially in the handle. In fact, the rod and the ejector element are preferably arranged entirely within the handle when the detaching device is in its cleaning position. Hence, it is preferred that the handle is essentially hollow and preferably corresponds to a hollow bar.
  • the ejector element can have various shapes.
  • the ejector element can have an uneven shape.
  • An uneven shape could be provided by means of a serration, jags, spikes, indents, etc. that are preferably provided at a distal end of the ejector element.

  • One or more of these elements are preferably provided in a distal region or at the distal end of the ejector element such that they can act on the cleaning pad when the detaching device is in the detaching position. These one or more elements serve the purpose of facilitating a uniform detachment of the cleaning pad from the cleaning head.
