According to the present invention, suction nozzle has brush 55,56,57, and described brush can pass base plate and pack up.Brush 55 is between suction passage 20 and edge 5, and brush 56 is between suction passage 19 and edge 6. Passage 19 and 20 converges in the front portion of suction nozzle, forms an inverted V-shaped, and back brush 57 is followed this shape, the part of meeting along edge and they that two passages form.Shown in Fig. 3,4, after be brushed with one in the middle of brush, promptly a breach 157 is arranged at the basin shape of described brush place, be convenient to when suction nozzle moves backward, suck the rubbish of this shape that may be arranged in brush.
Fig. 3,4,5 illustrates the controlling organization that brush and described brush stretch out respectively.A special character of this device is, except the position of pedal, and a relative vertical mid-plane symmetry vertical fully with suction nozzle.
Pedal 8 has a side direction plush copper 81, and the vertical part 82 that is used for can seeing by a Fig. 9 is connected with the suction nozzle base plate, and vertical part 82 has a hole, and described plush copper is positioned at wherein.The plush copper that is arranged in part 82 like this constitutes a rotating shaft of pedal.Pedal also has a hollow extension 83.
In addition, pedal 8 is connected with a rigid rod 28 that transmits motion, and this bar is fixed on the pedal, in the extended line of pedal shaft, promptly in the extended line of plush copper 81, as shown in Figure 4.This bar has the elbow of a special shape of several formations, and the particularity of this special shape is to keep the plane, forms a horizontal component 280 and two basic vertical parts 282, and horizontal component 280 is the part that is connected with pedal.Two basic vertical parts 282 are positioned at each end of bar, and each part is connected with a carriage 85,86.Be arranged in the hollow parts that pedal 8 following vertical components 282 reach pedal extension 83, so a guiding device of pedal formation bar, and guarantee power is passed to bar.
In addition, two vertical bearings 128 that stretch out from base plate support described bar 28.
Carriage 85,86 is two identical L shaped parts, has a quite long horizontal component and short part downward vertically of pointing to the suction nozzle front portion.These carriages are fixed between suction nozzle base plate and the case, and it can only be moved horizontally to the forward and backward of suction nozzle.Two arches 194 of stretching out from base plate can forbid that any of described carriage moves both vertically, and carriage 85,86 passes arch 194 and installs.
The front end of the horizontal component of each carriage 85,86 has a processing shape in the slope, is respectively 185,186.When described carriage moved horizontally, these were processed part in the slope and constitute and can interact with identical chamfered portion 125,126 in the corresponding individual part 75,76 that is called trigger.The top of chamfered portion 125,126 arrives on the planar section 25,26 of a basic horizontal.
Therefore, each carriage 85,86 can interact with trigger 75 and trigger 76 respectively.It in the suction nozzle substantially is the part on plane that trigger is mounted in, a vertical direction one degree of freedom is arranged, remain on by the suction nozzle base plate between the trip of their basic horizontal in (debattement), for example by a sliding pin 192 that stretches out from base plate, trigger can be by sliding on pin with pin 192 corresponding opening 175,176.In order to reduce the friction between trigger and the base plate, each pin or in them some can have gaudrons or little vertical protrusion, are convenient to the vertical of trigger and move.
Advantageously, base plate also is equipped with the gaudrons that can remain on carriage the brush extended position under each carriage, to avoid the accidental activation of mechanism.
As seeing among Fig. 9, a spring 165,166 is installed between each trigger 75,76 and the suction nozzle base plate.
Each trigger has the groove 65,66 that is used for brush 55,56, and each brush mainly remains in the groove by the elasticity clamping of clip 95,96 types.In addition, realize the stopping downwards of trigger stopped that the periphery by the brush groove constitutes by the stop area of motion vertically downward of trigger.Contacting of consequent and suction nozzle base plate appropriate section guarantees good sealing property.
Half that makes back brush 57 by clip 97,98 kept by each trigger, and the same with brush 55,56, when brush stretches out, by contacting downward the stopping of realization trigger between brush groove periphery and the base plate.
During work, from being equivalent to the position that Fig. 6,8 brush regain, the chamfered portion 125 of trigger and 126 and the chamfered portion 185,186 of carriage be in same place substantially side by side.
When needs stretched out brush, the user started pedal by the rear portion that is pressed in pedal.The clockwise direction of pedal in figure rotates, and causes bar 28 to rotate to same direction.
Substantially vertical part 282 is also rotated, and the carriage 85,86 that causes being connected with the end 282 of described bar moves forward.The chamfered portion that drives carriage that advances of carriage cooperates with the chamfered portion of trigger.Because carriage can not move both vertically, and trigger can not horizontal movement, trigger bears downward moving both vertically under the travelling forward of carriage, the returning place force of antagonistic spring 165,166, the gap on inclined-plane makes trigger 75,76 slide into carriage 85,86 times, and carriage 85,86 rests on respectively on the planar section 25,26.
Stretch out on the plane that this motion vertically downward of trigger can form brush from the bottom of base plate.
When the user need regain brush, pedal is rotated counterclockwise, the end 282 of bar is driven backward, causes the same motion of carriage 85,86.In case the chamfered portion of carriage and trigger is corresponding, the returning place force of spring can pass through its effect on trigger, quickens the rising of trigger and returning backward of carriage.
The invention is not restricted to shown embodiment, but comprise the technology of equivalence.Particularly, back brush 57 can be reduced to two straight line portioies that separate, and each part is kept by their triggers separately simply.It is also conceivable that in the both sides of tube connector 2 two pedals are set, each pedal acts on its carriage, even acts directly on separately the trigger.
