Definitions

  • the present invention relates to the field of cleaning devices and, more particularly, to a bagless hand-held vacuum cleaner, otherwise known as a cyclonic hand-held vacuum cleaner.
  • Such a vacuum cleaner is intended to be compact and carried with one hand to vacuum low surfaces, for example a worktop or staircase steps, or raised surfaces, for example a ceiling or a wall or even furniture arranged in height.
  • Bagless hand-held vacuum cleaners are known to those skilled in the art.
  • a vacuum cleaner comprises a body which is provided at the rear with a gripping handle and which incorporates suction means.
  • the vacuum cleaner also comprises a suction tube through the front end of which the impurities are sucked and a filtration chamber arranged between the suction tube and the suction means on the body to receive and temporarily store the sucked impurities.
  • the filtration chamber comprises a bowl which communicates with the suction tube and a filter element which is housed in the bowl and which communicates with the suction means.
  • the air flow When the suction means are activated, the air flow generates a vacuum making it possible to suck up the impurities through the front end of the suction tube; the flow of air laden with impurities circulates in said tube then enters the bowl where the impurities remain trapped largely thanks to a centrifugal force generated in this bowl, while the filter element arranged downstream (taking into account the direction of circulation of the air flow) makes it possible to retain the fine particles of impurities, the filtered air flow then continuing its circuit in the body under the action of said suction means, to be finally rejected from said body, by example on the back of it.
  • the suction tube is integrated into the bowl, the assembly being assembled with the body.
  • the bowl comprises in the lower part a hatch whose opening is effected by means of a remote control, the opening of the hatch making it possible to empty the bowl.
  • This remote control is configured to concomitantly extract the filtering element from above the bowl, in order to guarantee regular cleaning of the filter element each time the bowl is emptied.
  • the tube, bowl and filter element assembly is removable from the body to allow complete cleaning of the bowl, the assembly being extracted using the remote control.
  • the suction tube is integrated into the bowl, the assembly being removable from the body.
  • assembly means are implemented between a rear face of the bowl and a front face of the body.
  • the rear and the front are defined respectively opposite the positions of the grip handle and the suction tube on the vacuum cleaner.
  • the bowl has a hatch in the lower part.

  • the second gripping handle is mounted on the suction tube.
  • the length and diameter of the first and second handles are substantially identical.
  • the vacuum cleaner can be handled identically by a left-handed or right-handed user without the use differing from one user to another.
  • a guiding and holding system is arranged between a rear face of the bowl and a front face of the body to engage the bowl on the body until a position of formation of said suction chamber is reached or conversely, to release the bowl from the body until it reaches a separation position.
  • Said guiding and holding system is configured to accompany the movement of the bowl on the body during its engagement or its release.
  • a locking system is arranged between an upper front part of the bowl and a front part of the body to lock the bowl on the body in the position of forming the suction chamber or to unlock the bowl from the body so as to release it.
  • the guiding and holding system is configured to engage the bowl on the body by pushing it backwards on the body, or vice versa when it is released from the body by pulling it forward on the body.
  • the locking system comprises at least one bolt arranged on the second handle and at least one keeper arranged on the body.
