Valve cell 218 also comprises one wheel pairs 236, and it is rotatably installed in the recess on the opposite side being arranged in valve actuator 230.One or more extra wheel can be arranged on front or the rear of valve actuator 230.Wheel 236 protrudes past valve actuator 230 downwards from the lower surface of the housing 220 of valve cell 218, and when being positioned at hard ground surface to make surface member 110 expediently, valve actuator 230 can not contact with floor surface.Wheel 236 is relative narrower compared with wheel 114, and it is little compared with wheel 121, when carpeting floor surface to make face instrument 110 expediently be positioned at, wheel 236 is trapped in the tuft of floor surface at least in part, to be contacted with floor surface by valve actuator 230.
In use, ground instrument 110 is attached to vacuum cleaner 86 in the mode being similar to ground instrument 10.When user opens vacuum cleaner 86, the motor of vacuum cleaner 86 is energized and drive fan, to be sucked by ground instrument 110 by dirty air.As a result, relatively low air pressure is formed in suction chamber 120 and outlet 134.
See Figure 13 a, 13b and 13c, when ground instrument 110 contacts with hard ground surface 240, valve actuator 230 is spaced apart with hard ground surface 240 by wheel 236.As a result, when ground instrument 110 operates on the surface at hard ground, valve actuator 230 will remain in its non-position of rotation under the effect of the biasing spring be applied to it.And then valve 222 will remain in its second place, in this position, the basic and fluid flow port 224 of fluid line 204 will be kept apart.As a result, the air pressure in pressure chamber 202 is basic identical with the air pressure in the outlet 134 of suction chamber 120, so produce relatively large pressure differential by the air pressure in pressure chamber 202 and between the atmospheric pressure of pressure chamber 202 outside.By the biasing force of atmospheric pressure effect opposing elastic component 212, upper chamber's section 206 is actuated and moves towards lower chambers section 208, as shown in the arrow 216 of Figure 15 a, to make pressure chamber 202 be maintained at its contraction structure, brush unit 190 is in its expanded position in the structure shown here.
As depicted in fig. 13 a, at the expanded position of brush unit 190, mane 194 protrudes past the working edge 140,142,144,146 of main body 112 downwards, with make working edge 140,142,144,146 and hard ground surface area 240 spaced apart.This can prevent hard ground surface 240 by working edge 140,142,144,146 scratching or delineation when ground instrument 110 operates in floor surface 240.In addition, in the expanded position of brush unit 190, capping unit 192 engages with the upper surface 152 of main body 122, and this makes air channel 148 substantially be opened with isolated from atmosphere by the part being located immediately at the covering 192 above it.This can make in suction chamber 120, to produce lower pressure in the use procedure of ground instrument 110, and this can improve the situation in the air-flow of the foul in the pit on hard ground surface 240 and chip inspiration suction chamber.Castellation (not shown) in the part of mane 194 ranking near the front surface 130 of main body 112 is allowed in the forward stroke of ground instrument 110 on hard ground surface 240, the chip be arranged on hard ground surface 240 is inhaled into suction chamber 120.According to working edge 140,142, the size in gap between 144,146 and hard ground surface 240, this chip can enter the second suction passage 124 through the below of working edge 140,142,144 in the gas flow, and arrives the outlet 134 of suction chamber 120 from this.Similarly, the chip sucked from the gap hard ground surface 240 and foul also trend towards directly entering the second suction passage 124.
See Figure 14 a, 14b and 14c, when ground instrument 110 carpet floor surface 250 operates time, wheel 236 is trapped in carpets in the tuft of floor surface 250, and valve cell 218 is moved relative to main body 112 floor surface 250 of downwardly carpeting.This makes valve actuator 230 contact with floor surface 250 of carpeting.Ground instrument 110 carpet floor surface 250 is pushed with stroke forward time, such as, valve actuator 230 and the joint of carpeting between floor surface 250 make valve actuator 230 turn clockwise (as shown in fig. 14b) to the first position of rotation.Cam 234 in valve chamber 226 rotates to the position shown in Figure 14 c from the position shown in Figure 13 c together with valve actuator 230, to shift valve 222 onto its primary importance, as shown in figure 14 c.Fluid line 204 is exposed to fluid flow port 224 to the motion of its primary importance by valve 230, and is exposed to air thus.As a result, the air pressure in pressure chamber 202 rises relative to the air pressure in the outlet 134 of suction chamber 120, and air pressure thus in pressure chamber 202 and the difference between the atmospheric pressure of pressure chamber 202 outside reduce.This makes the biasing force of flexible member 212 can actuate upper chamber's section 206 and leaves lower chambers section 208, and brush unit 190 is moved to its deposit position from its expanded position relative to main body 112.
As shown in figures 14a, in the deposit position of brush unit 190, mane 194 is positioned at above the working edge 140,142,144,146 of main body 112, to make working edge 140,142,144,146 contact with floor surface 250 of carpeting, thus provide brushing action at ground instrument 110 when carpeting and floor surface 250 operating.In addition, in the deposit position of brush unit 190, capping unit 192 is spaced apart with the upper surface 152 of main body 122, and this can expose air channel 148.As a result, air is drawn into air channel 148 by the window 196 of covering 192.This air passes conduit 148 and passes through on working edge 142,144.
When ground instrument 110 carpet floor surface 250 is pushed forward time, to enter and the air-flow passing suction chamber 120 is similar to and enters and pass the air-flow of the suction chamber 20 of ground instrument 10.Front working edge 140,144 launches the tuft of carpet, can flow through to make sucking air around front working edge 140,144 and enter suction passage 122,124.Air at the antetheca 130 times of main body 112, to suck for 140 times at front working edge and to enter into the first suction passage 122 of suction chamber 120.Air from the first suction passage 122 flows through center-aisle 136 and enters the second suction passage 124, and leaves suction chamber 120 by outlet 134.Air also passes through air channel 148 from air, sucks in the below of front working edge 144, and enters the second suction passage 124 of suction chamber 120.Air from the second suction passage 124 leaves suction chamber 120 by outlet 134.
When ground instrument 110 pulls back along floor surface 250 of carpeting, the tuft of floor surface of carpeting 250 make valve actuator 230 resist the biasing force of spring action on valve actuator 230 and from its first position of rotation rotate to the second position of rotation.Valve actuator 230 second position of rotation be the mirror image of the first position of rotation substantially.When valve actuator 230 is when moving between position of rotation for these two, the rotation of cam 234 makes valve 222 swing rapidly in valve chamber 226, returns its primary importance subsequently from its primary importance to its second place.As a result, brush unit 190 remains on its deposit position in the stroke backward of ground instrument 110.In the trip, air is sucked for 142 at rear working edge from air by air channel 148, and enters into the first suction passage 122.Air from the first suction passage 122 flows through center-aisle 136 and enters the second suction passage 124, and leaves suction chamber 120 by outlet 134.Air also below the rear wall 132 of main body 112, suck below rear working edge 146 and enter the second suction passage 124.Air from the second suction passage 124 leaves suction chamber 120 by outlet 134.
Thus, by the driving mechanism 200 providing brush unit 190 and automatically moved between deposit position and expanded position by brush unit 190 for the feature of the floor surface operating place according to ground instrument 110, the pickup capacity of structure in both carpet surface and hard ground surface of ground instrument 110 can be optimized.
