Definitions

  • the present invention relates to a squeezing device for squeezing a cleaning device such as a mop according to claim 1, to a lid for a cleaning bucket comprising such a squeezing device according to claim 10, to a cleaning bucket comprising such a lid according to claim 13, and to a method of manufacturing a squeezing device according to claim 15.
  • Cleaning devices such as mops for cleaning floors are well-known in the art. These cleaning devices can be used for wet cleaning as well as dry cleaning. In the former case, the cleaning device is wetted for instance by inserting the cleaning device in a cleaning bucket comprising water or soap. In the latter case, the cleaning device is used in a dry state wherein it binds loose dust and lint, for example.
  • the cleaning device can be easily converted from a wet state into a dry state and vice versa. This is usually done by pressing a wetted cleaning device to a desired wetness state such as completely dry, slightly wet or fully soaked.
  • a desired wetness state such as completely dry, slightly wet or fully soaked.
  • several devices are known from the state of the art that allow a corresponding setting of a wetness state.
  • CN 214 048 710 U discloses a squeezing device for a mop, which permits the setting of a squeezing quantity.
  • the device comprises slideable seats and a locking control unit.
  • two water squeeze-out units are provided, which are relatively rotatably arranged in an installation cavity.
  • a water squeezing space is formed between the two squeezing units, which is adjustable by a distance between the slidable seats.
  • the locking control unit includes an interlock control screw and a lift slide seat having displaceable lift slide parts. Actuation of the screw causes movement of the seats toward or away from each other, thereby realizing two water squeezing units.
  • the distance between the two water squeezing units decreases and the water squeezing force increases. Conversely, when the distance between the water squeezing units increases, the squeezing force decreases.
  • CN 211 299 844 U discloses a cleaning bucket comprising a bucket lid, a squeezing part, and an adjusting device.
  • the lid is provided with a hole and the squeezing part is connected to the adjusting device.
  • the adjusting device is used to adjust the position of the squeezing part to adjust the size of the hole.
  • the adjusting device includes a bracket, a slider, a movable frame, and an adjustment screw.
  • the screw is turned in a first direction of rotation, causing the slider to slide down the bracket with the frame driving the squeezing part to slide in a first direction and reduce the size of the hole so that the squeezing part squeezes more liquid out of the mop.
  • the screw is rotated in a second direction so that the slider slides upward on the bracket. In doing so, the frame drives the squeezing part to slide in a second direction to increase the size of the hole so that the squeezing part squeezes less fluid from the mop.
  • a major disadvantage of the devices of the prior art is the large number of interacting parts needed for the squeezing of the mop. This makes the production of the squeezing devices complex and expensive and the squeezing devices are furthermore prone to failure and wear.
  • a squeezing device for squeezing a cleaning device such as a mop.
  • the squeezing device comprises at least one pressing element, at least one counterpressing element, and at least one adjusting device.
  • the pressing element and the counterpressing element are arranged at a distance from one another and are configured to exert a squeezing force on a cleaning device disposed between the pressing element and the counterpressing element.
  • the adjusting device is configured to adjust the squeezing force being exertable by the pressing element and the counterpressing element.
  • the adjusting device comprises at least one selector element and at least one shifting element.
  • the selector element is configured to adapt at least a first position and a second position upon an actuation.
  • the selector element further comprises at least a first recess and a second recess, wherein the first recess and the second recess extend into the selector element to different extents.
  • the shifting element is in connection with the pressing element. The shifting element is at least partially received in the first recess when the selector element is in the first position and is at least partially received in the second recess when the selector element is in the second position, whereby the distance between the pressing element and the counterpressing element and thereby the squeezing force is adjustable.
  • the sequeezing device comprises a pressing element and a counterpressing element that are arranged at a distance from one another and between which the cleaning device can be arranged.
  • Said distance preferably extends perpendicular to an insertion direction along which the cleaning device is insertable into the squeezing device.
  • the pressing element and the counterpressing element are preferably arranged horizontally spaced from one another such that they define a horizontal distance between one another, and wherein the cleaning device is insertable between the pressing element and the counterpressing element along a vertical direction running perpendicularly to the horizontal direction.
  • the pressing element and the counterpressing element are arranged and configured such, that they can exert a squeezing force onto the cleaning device.
  • the pressing element and the counterpressing element are preferably arranged and configured such, that they exert a squeezing force onto the cleaning device during the insertion of the cleaning device into the squeezing device and/or while the cleaning device is inserted in the squeezing device and/or during the removal of the cleaning device from the squeezing device.
  • the pressing element and the counterpressing element are arranged at a distance that essentially corresponds to or is smaller than a thickness of the cleaning device in a region of the cleaning device that is to be squeezed by the squeezing device.
  • the cleaning device preferably corresponds to a mop and particularly preferably is a flat mop.
  • the cleaning device preferably comprises a rod and a head being rotatably attached to the rod, wherein the head can adapt at least a position wherein it runs perpendicular to the rod and a position wherein it runs parallel to the rod.
  • the former position can be referred to as cleaning position that allows a cleaning with the mop and the latter position can be referred to as stowed position that allows the mop to be stowed in a space-saving manner.
  • the cleaning device comprises a wiper or the like being disposed on the head.
  • the head is of a flat shape, i.e. a plate-like shape.
  • the squeezing device is preferably configured to squeeze a flat mop, wherein the flat mop is insertable into the squeezing device in its stowed position such that the pressing element and the counterpressing element can press against an upper side and a lower side of the head, whereby the head is squeezed to a desired extent and as defined by the distance between the pressing element and the counterpressing element.
  • the lower side of the head faces the floor or the like to be cleaned and the upper side of the head is arranged opposite to the lower side and faces towards a user of the mop.
  • the pressing element and the counterpressing element have to be arranged at a distance from one another that essentially equals to or is smaller than the thickness of the head.
  • the thickness corresponds here to the thickness of the head running from the upper side to the lower side of the head.
  • the distance between the pressing element and the counterpressing element defines the squeezing force that can be exerted onto the cleaning device and as such a wetness state to be achieved in the cleaning device.
  • wetness states are completely dry, slightly wet, fully soaked, etc.
  • the user has to actuate the adjusting device, wherein the adjusting device adjusts the distance between the pressing element and the counterpressing element and thus the squeezing force.
  • the distance between the pressing element and the counterpressing element is adjusted via the adjusting device.
  • the adjusting device comprises at least one selector element having two or more recesses that extend into the selector element to different extents.

  • said shifting element can at least partially be inserted into one of the recesses of the selector element at a time.
  • An amount by which the shifting element protrudes from the recess depends on the length of the recess. For instance, if the recess is only short, a major part of the shifting element will protrude from the recess. However, if the recess is long, a major part of the shifting element will be received in the recess and only a small part of the shifting element will protrude from the recess.
  • a distance between the pressing element and the counterpressing element depends on the length or extend of the particular recess the shifting element is inserted. In fact, the longer the recess, the smaller the distance between the pressing element and the counterpressing element.
  • the pressing element when the shifting element is inserted into a first recess of the selector element, the pressing element is arranged at a first distance from the counterpressing element.
  • the shifting element is inserted into a second recess of the selector element being longer (smaller) than the first recess, the pressing element is arranged at a second distance from the counterpressing element being smaller (longer) than the first distance.
  • the pressing element is preferably moved towards the counterpressing element upon insertion of the shifting element into a smaller recess or is moved away from the counterpressing element upon insertion of the shifting element into a larger recess.

That is, by rotating the selector element the shifting element is inserted into a particular recess of the selector element.
  • the selector element can adapt its different positions or be rotated only in the event that no cleaning device is inserted between the pressing element and the counterpressing element. Namely, in the event of a cleaning device being inserted between the pressing element and the counterpresing element the shifting element is prevented from moving out of the particular recess it is inserted in because of the pressing element pressing against the cleaning device. The shifting element being inserted into a recess of the selector element thereby provides a rotation stop for the selector element and fixes the selector element in its particular position.
