The specific embodiment
Below in conjunction with the whirlwind type dust collect plant that be used for vacuum cleaner of accompanying drawing detailed description according to the preferred embodiment of the invention.
Fig. 2 has shown the decomposition diagram of upright vacuum cleaner, and it has adopted whirlwind type dust collect plant according to embodiments of the present invention.
Please referring to Fig. 2, whirlwind type dust collect plant comprises cyclone body 50, dust collection container 60, filter assemblies 70 and dedusting part 90 according to embodiments of the present invention.
Cyclone body 50 is divided into upper body 51 and sub-body 52.Upper body 51 links to each other by a plurality of screws 53 with sub-body 52.Sub-body 52 has first tube connector 54, and this first tube connector 54 links to each other with extension 1a on the dust catcher air inlet side, and has air inlet 55, and this air inlet 55 communicates with first tube connector 54.Upper body 51 has second tube connector 56, and this second tube connector 56 links to each other with extension 1b on the main body of dust collector side, and has exhaust outlet 57, and this exhaust outlet 57 links to each other with second tube connector 56.
The air that contains impurity that air inlet by dust catcher sucks is through the incline direction inflow along relative cyclone body 50 of first tube connector 54 and air inlet 55.Therefore at cyclone body 50 and the dust collection container 60 inner eddy current that form, the impurity that contains in the air is separated by the centrifugal force that eddy current produces.
Dust collection container 60 links to each other with the exhaust outlet 57 of cyclone body 50 removably.Dust collection container 60 makes leaked-in air produce eddy current with cyclone body 50, and collects by whirlwind isolated impurity from air.
Please referring to Fig. 3 and Fig. 4, filter assemblies 70 is arranged on the exhaust outlet 57 of cyclone body 50, is used for preventing that the impurity of collecting at dust collection container 60 from flowing backwards by exhaust outlet 57.This filter assemblies 70 comprises: the pipe fitting 71 that links to each other with exhaust outlet 57; Lid 73; Rotatably support the axle 75 of lid 73; With revolving filter 77, it is arranged on the bottom of pipe fitting 71, as shown in Figure 3.
Revolving filter is arranged on the lower end of pipe fitting 71, and is rotatably supported by axle 75.This revolving filter 77 comprises: the turbine 81 that is installed in pipe fitting 71 bottoms; Cover the screen pack 83 of the outer surface of turbine 81; The adverse current stop 85 that links to each other with turbine 81 lower ends.Turbine 81 has along the circumferential direction a plurality of rotation wing 81a that are provided with preset space length, therefore is subjected to flowing into the rotation of the air of pipe fitting 71.Screen pack 83 rotates on outer surface with turbine, is used to filter the tiny dust that is not separated by centrifugal force in the dust collection container.Adverse current stop 85 is fixed on the lower end of axle 75 by the screw 53 in turbine 81 bottoms.Therefore, revolving filter 77 can be around axle 75 rotation together.Adverse current stop 85 flange portion 85a, its lower end stretches out, thereby stops light impurity adverse current.
Simultaneously, pipe fitting 71 has the dedusting part 90 that is placed on its external end part.That is, an end of dedusting part 90 is fixed on the end of pipe fitting 71, and its other end is positioned at the outer surface of screen pack 83.The side of dedusting part 90, promptly the downside of dedusting part 90 has dust removal brush disposed thereon 91, and dust removal brush 91 contacts with screen pack 83.
In addition, dedusting part 90 setting that has a down dip on the direction of rotation of turbine 81 is promptly along the direction setting (Fig. 3) of tilting with turbine 81 direction of rotation.Therefore, dust and impurity are brushed away from screen pack 83 and are fallen when revolving filter 77 rotations, no longer rest on the dedusting part 90.This dedusting part 90 can be fixed on the pipe fitting 71 by screw, perhaps connects by known connection means.
The running of the above-mentioned type of whirlwind according to embodiments of the present invention dust collect plant will be described below.
As shown in Figure 5, whirlwind type dust collect plant links to each other with extension 1a, the 1b of dust catcher according to embodiments of the present invention, and mode is the same with traditional whirlwind type dust collect plant.When dust suction began, dust flowed into along the direction that relative cyclone body 50 tilts by first tube connector 54 and air inlet 55 with the suction that impurity and inhaled air are subjected to producing at dust catcher air entry place together.Therefore, air produces eddy current and descends to the bottom of dust collection container 60.In this process, the dust that contains in the air is separated from air by centrifugal force with impurity, and is collected in the dust collection container 60.
Subsequently, air is subjected to rising in dust collection container 60 bottoms the air-flow effect of returning and screen pack 83 and turbine 81 by filter assemblies 70 flows into pipe fittings 71.The air that flows into pipe fitting 71 is discharged by extension 1b.At this moment, a part of impurity that rises with air-flow in dust collection container 60 is subjected to adverse current stop 85 to be stopped, thereby sinks with eddy current.
In addition, the impurity that is not separated by adverse current stop 85 is filtered net 83 filtrations.Therefore, tiny dust is filtered net 83 and catches, and the air of cleaning is discharged by filter screen 83 and through turbine 81.The air effect that turbine 81 is discharged is promptly rotated along the A direction clockwise.Therefore, screen pack 83 and turbine 81 rotate together, constantly keep in touch with dedusting part 90 simultaneously, thereby the impurity that utilizes dedusting part 90 will cover screen pack 83 are removed.Therefore, can prevent that air vent is capped the impurity obstruction of screen pack 83.In addition, because screen pack 83 dedusting does not automatically need dismounting separately and cleaning filter assemblies 70 when emptying dust collection container 60.
Though embodiment of the present invention have only illustrated the filter assemblies 70 with single dedusting part 90, can a plurality of dedusting parts 90 be set according to predetermined space.
According to the present invention, the whirlwind type dust collect plant that is used for vacuum cleaner has such structure, and when the revolving filter of filter assembly was rotated by air effect automatically, screen pack can carry out automatic dedusting by the dedusting part.
Therefore, can prevent that revolving filter from being blocked by dust, thereby improve cleaning efficiency, and, use convenient owing to do not need the separate cleaning revolving filter.
Above-mentioned embodiment and advantage just schematically, can not limit the present invention.Principle of the present invention can be used for the device of other types.Specification of the present invention is used to illustrate, but not is used for limiting the scope of claim.But those of ordinary skill in the art can make these specific embodiments and improving and distortion.In claims, device+function statement is to be used for covering the described structure of carrying out described function, not only comprises equivalent structures, also comprises equivalent configurations.
