DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 of the drawing shows a spray extraction nozzle 1 with a suction duct 2 and a suction mouth 3. An adapter 5 is connected to the spray extraction nozzle 1 through a pivot axis 4, 4′. The pivot axis 4 can be displaced in the longitudinal direction thereof through an actuating device 6 so that, when the actuating device 6 is pressed in, the pivot axis 4 is moved out of the bore 7 of the adapter 5. Consequently, the adapter 5 becomes free at one of its two points of suspension and can be removed and replaced with a new or a different adapter.
FIG. 1 further shows a locking device 8 which can be moved downwardly against the force of springs, not shown. Hooks 9 in the form of barbed hooks are arranged at the lower end of the locking device 8. The barbed hooks can engage in appropriate counter hooks of the adapter 5. The effect of the barbed hooks ensures that, when a transverse load occurs or bending of the adapter 5 occurs, the adapter 5 is always more strongly engaged with the locking device 8, so that an unintentional folding away of the adapter 5 is prevented.
In the illustration of FIG. 2, the adapter 5 is pivoted in front of the suction mouth 3, and the locking device 8 holds the adapter 5 in the position of operation as it is illustrated in the drawing.
FIG. 3 shows the spray extraction nozzle 1 in a rear view. In this view, hooks 10, 10′ can be seen which hold the adapter 5 in the position of rest. The hooks 10, 10′ are snap hooks which, by simple actuation of the adapter 5, for example, by a foot, snap resiliently apart from each other and release the adapter 5 from the position of rest.
Different from the suction mouth 3 which has two fixed lips 11, 11′, the adapter 5 has at least one bristle ledge 12 and at least one rubber lip 13 by means of which liquids can be pushed together in an optimum manner on hard surfaces and can then be suctioned off.
FIG. 3 further shows a locking mouth 14 into which a spray nozzle can be placed. The spray nozzle is downwardly aligned between guide elements 15, 16 in such a way that the spray jet cannot be sprayed laterally beyond the guide elements 15, 16. As a result, walls and furniture do not become wet when the spray extraction nozzle is used nearby.
Moreover, the drawing shows a support surface 17 of the adapter 5 which is in the same plane as the lips 11, 11′ when the adapter 5 is in its position of rest. When the support surface 17 rests on the surface to be worked on, it ensures that the lips 11, 11′ are in the optimum suction position, so that the residual moisture can be minimized.
FIG. 4 shows a sectional view of the spray extraction nozzle 1, wherein the Figure particularly shows the suction duct 2 and the suction mouth 3 with its lips 11, 11′. The lip 11′ serves as a stop for the adapter 5. When the spray extraction nozzle 1 carries out a pulling movement, the adapter 5 is pulled against the lip 11′ which serves as a stop. In addition, the bristle ledge 12 and the rubber lip 13 of the adapter 5 can be seen, as well as the locking device 8 which engages with its hooks 9 in appropriate counter hooks 9′ of the adapter 5. When the spray extraction nozzle 1 carries out a pushing movement, the hooks 9 and the counter hooks 9′ are pulled more and more together, so that the adapter 5 cannot be pivoted. Only when the locking device 8 is pushed, for example, by a foot operation, the hooks 9 slide out of the hooks 9′.
All Figures of the drawing show the essentially triangular shape of the spray extraction nozzle 1, wherein, however, projections 18, 18′ are arranged in the lower area in such a way that it is possible to operate underneath pieces of furniture so that no edges which are not worked on are visible.
While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
