The specific embodiment
Below in conjunction with drawings and Examples explanation the present invention.
Fig. 4 is the schematic perspective view of vacuum cleaner that is provided with the rotary brush of one embodiment of the invention.A kind of as shown in the figure vacuum cleaner comprises the inner body housing 101 that receiving space is provided with along vertical direction that forms; Be arranged on described body housing 101 inside, produce the fan electromotor (not showing among the figure) of suction; Be arranged on the suction side of fan electromotor (not having among the figure to show), the filter 103 that stops foreign matter to pass through; Be arranged on around the filter 103, the filter housing 104 by the foreign matter of filter blocking-up is accommodated in inside; Be arranged on body housing 101 downsides, suck the suction nozzle 105 of fluid from the outside; Form in described suction nozzle 105 bottoms, suck the suction inlet 111 of external fluid; Be arranged on the described suction inlet 111 inboard suction nozzles 112 of collecting the fluid that sucks from the outside: being arranged on the inboard of said suction nozzle 112, is the rotatable rotary brush 113 in center with the rotating shaft.
In addition, the side of body housing 101 lower ends forms exhaust outlet 118, the fluid that described exhaust outlet 118 is discharged through fan electromotor.Exhaust outlet 118 is combined with the hood 119 (cover) that forms a plurality of exhaust hole 119a.
As Fig. 5, Fig. 6, shown in Figure 7, above-mentioned rotary brush 113 comprises a pair of bristle fixed station 122, two ends connecting portion 123, bristle 124.Described bristle fixed station 122 is along the outer peripheral face of the supposition cylinder of being represented by chain-dotted line 120 and spiral formation, and the bristle fixed station makes that forming the fluid that fluid passes through in the supposition cylinder passes through the space; Two ends connecting portion 123 is arranged on the two ends of bristle fixed station 122, and fasten bristles fixed station 122 rotatably; Bristle 124 is arranged on the bristle fixed station 122, is used to clear away ground dust or foreign matter.
The fixed disk 131 that two ends connecting portion 123 comprises disc-shape and pole shape be connected projection 132.The medial surface 131a fasten bristles fixed station 122 of described fixed disk 131, its lateral surface 131b is formed with cylinder 116 in the mode of one; Described connection projection 132 connects projection 132 fixed disk 131 rotatably is fixed on the said suction nozzle 112 in the alongst outstanding formation of the middle body of the lateral surface 131b of described fixed disk 131.
The course of work of vacuum cleaner with the invention described above rotary brush is as follows.
After the user connected power supply to dust catcher, the fan electromotor rotation also produced suction, sucks outside fluid by suction inlet 111.The fluid and the foreign matter that are inhaled into by suction inlet 111 enter filter housing 104 inside by suction nozzle 112 collection backs along suction pipe; The foreign matter that flow into filter housing 104 inside is collected in filter housing 104 inside by filter 103; Behind the fluid process fan electromotor by filter 103, be discharged to the dust catcher outside by exhaust outlet 118 at last.
When carrying out above-mentioned cleaning process,, be arranged on head roll 115 rotations of motor shaft according to the rotation of fan electromotor.By electronic driving-belt 117, the cylinder 116 that links to each other with head roll 115 also rotates.Be fixed with rotary brush 113 rotations of cylinder 116 then, along with the rotation of rotary brush 113, ground dust or foreign matter are inhaled into dust catcher inside by suction nozzle 112.
The fluid that sucks by suction nozzle 112 is the space by forming between suction nozzle 112 and the rotary brush 113 not only, and also the fluids by formation in the supposition cylinder 120 are inhaled into after by space 121.So the fluid that takes place to be caused by rotary brush 113 when sucking dust and foreign matter hardly flows and produces the problem of resistance, has improved cleaning performance thus significantly.
Fig. 8 is the schematic perspective view of a variant embodiment of the present invention.As shown in the figure, the basic structure of forming rotary brush 113 is same as the previously described embodiments, so same section is adopted same symbol.
In this variant embodiment, between a pair of bristle fixed station 122 alongst, a plurality of supporting ribs 141 of formation spaced a certain distance (rib).Described supporting rib 141 prevents that bristle fixed station 122 is subjected to flowing of fluid and deforms.
Fig. 9 is the schematic perspective view of another variant embodiment of the present invention.As shown in the figure, the basic structure of this variant embodiment is identical with the structure of Fig. 8.Between a pair of bristle fixed station 122 back shaft 151 is set alongst, the two ends of described back shaft 151 are fixed on the medial surface of fixed disk 131; Alongst spaced a certain distance a plurality of supporting ribs 152 are set.The middle body of described supporting rib 152 is fixed on the back shaft 151, and its two ends are fixed on the bristle fixed station 122.Back shaft 151 prevents that bristle fixed station 122 and supporting rib 141 from deforming.
