Definitions

  • Hard surfaces such as stone or wooden terraces, garage entrances and garage doors.
  • the pressure line of a high-pressure cleaner so that pressurized cleaning liquid can be supplied to the arranged on the spray arm nozzle.
  • the cleaning liquid can be sprayed onto the surface to be cleaned.
  • the nozzle undergoes a recoil, so that the spray arm is rotated. This makes it possible to apply a relatively large area within a short time with cleaning liquid.
  • at least two spray arms are used, each carrying a nozzle, wherein the nozzles are acted upon simultaneously with pressurized cleaning liquid. '
  • the switching device on a user-operable valve, wherein by means of the valve, a flow connection of a connection part of the surface cleaning head is selectively releasable to each held on a spray arm nozzles and / or to the auxiliary nozzle.
  • the valve has only two switch positions, alternatively, the nozzles respectively held on a spray arm or the additional nozzle can be supplied with pressurized cleaning liquid.
  • the valve has three switch positions. includes, so that in the third switching position all nozzles can be acted upon simultaneously with cleaning liquid.
  • the auxiliary nozzle is designed as a rotor nozzle with a nozzle housing which is provided in an end wall with a cup-shaped bearing for the front, spherical end of a nozzle bore having a passage bore and which has an insert part with at least one tangential bore for a liquid , through which the liquid in the nozzle housing about the nozzle housing longitudinal axis is set into rotation, so that the nozzle body rotates together with the rotating liquid and thereby rests with a contact surface at its periphery to the inner wall of the nozzle housing, wherein the longitudinal axis of the nozzle body relative to the longitudinal axis of Nozzle housing is inclined.
  • the valve piston 61 faces away from the circumferential collar 64 and, in a region of reduced outside diameter, carries a further annular groove in which a second O-ring 68 is arranged.
  • the diameter of the second O-ring 68 is smaller than the diameter of the first O-ring 67. It is chosen such that the valve piston 61 sealingly abuts the wall of the second central portion 56 when displaced in the direction of the annular bead 65, whereas it When displaced in the direction away from the annular bead 65, it is arranged at a distance from the wall of the first center section 53 of the valve bore 50, as shown in FIG.

Abstract

La présente invention concerne une tête de nettoyage de surface comprenant un boîtier en forme de capot ouvert vers le bas, boîtier dans lequel au moins un bras pulvérisateur est monté librement rotatif autour d'un axe de rotation. Ce bras pulvérisateur porte une buse qui peut être alimentée en liquide de nettoyage sous pression et qui tourne avec le bras pulvérisateur autour de l'axe de rotation afin de projeter un jet de liquide sur la surface à nettoyer. L'objectif de l'invention est de perfectionner la tête de nettoyage de surface de manière à pouvoir également projeter de manière simple du liquide de nettoyage sous pression dans les régions de coin de la surface à nettoyer. A cette fin, la tête de nettoyage de surface présente une buse supplémentaire, maintenue fixe en rotation, qui peut être alimentée en liquide de nettoyage sous pression.
