Stagnate so that contact element 9 and and then rotate element 8 revolved when ground suction nozzle 1 moves ahead mobile over a surface to be cleaned
Turn.Here, it is that ground suction nozzle 1 is being treated clearly that the operation principle of the ground transaucer 6 formed inessential for three dimensional symmetry
Whichaway moves on clean surface.Because the rotation of rotate element 8 causes operating element 10 also to swing, wherein,
Free end moves since the preferential position shown in Fig. 4 along spherical track.The interface of abutment element 12 correspondingly aspheric
Bend to face, wherein, radius of curvature 13 reduces since the shown preferential position of operating element 10, the preferential position with it is right
The axis of symmetry of junction overlaps.Thus abutment element 12 overcomes the reset force of spring 14 to be moved towards the direction of valve 17.Docking member
The movement of part 12 acts on simultaneously to move with the closure elements 27 that the integral type of abutment element 12 is formed, so as to cause valve 17
Open.Closure elements 27 are from the face adapted lifting of valve 17, so that between suction channel interface 25 and actuator interface 26
Fluid path 16 is released.As described in by Fig. 2 and Fig. 3, thus, it is possible to be vacuumized by suction channel 4 to actuator 7, this is most
Cause movement of the pump orifice 3 towards surface to be cleaned eventually.
If ground suction nozzle 1 is advanced towards hard ground again since the carpet position shown in Fig. 5, rotate element
8 contact element 9 reforms into preferential position, wherein, operating element 10 on the interface 11 of abutment element 2 from compared with
The zone migration of small radius of curvature 13 extremely has the region of large radius of curvature 13.Return if necessary can by it is extra, match somebody with somebody
The spring (not shown) for belonging to rotate element 8 is supported.Abutment element 12 is again close to the closing of rotate element 8, thus valve 17
Element 27 also is disposed in the face adapted of valve 17 simultaneously, so as to sealing fluid path 16.Actuator 7 is it is possible thereby to no longer pass through
Suction channel 4 is evacuated, and is outwardly moved away to be cleaned so as to cause the ventilation of actuator 7 and ultimately result in pump orifice 3
It is dynamic.
