1=G
2.For the ease of better understanding the present embodiment, please in the lump with reference to figure 7, the figure shows the force analysis schematic diagram of deashing mechanism second specific embodiment.
It should be noted that, except above-mentioned two kinds of specific embodiment, also can reach one in two dust cleaning brushs 4 by other various ways and the moment of drive-connecting shaft 2 is greater than to the purpose of another one, those skilled in the art can realize fully according to prior art, so do not repeat them here.
Further, in this programme, two dust cleaning brushs 4 all are connected by the pivot joint mode with the end of articulated part 5, in view of two dust cleaning brushs 4 all offset all the time with the corresponding face that gathers dust of the positive plate 3 that gathers dust, when the positive plate 3 that gathers dust moves along loop under the driving mechanism effect, produce frictional force between the contact-making surface of dust cleaning brush 4 and the positive plate 3 that gathers dust, under this frictional force effect, both relatively rotate, can make the whole external circumferential of dust cleaning brush 4 participate in the deashing operation, thereby can improve the utilization rate of dust cleaning brush 4, certainly will increase like this cycle of changing dust cleaning brush 4, and then extend its service life, reduce the maintenance cost of moving anode electric cleaner.
Be appreciated that two dust cleaning brushs 4 in this programme also can directly be fixedly connected with articulated part 5 on the basis that meets the specific collection area dirt function of removing the positive plate 2 that gathers dust.
In addition, refer to Fig. 5, each dust cleaning brush 4 in this programme comprises the brush roll 41 of both ends and articulated part 5 pivot joints correspondingly and is arranged at the bristle 42 on brush roll 41.Wherein, the setting of bristle 42 on brush roll 41 can adopt various ways to realize, at this, only introduces both specific embodiment, is respectively:
The first, this bristle 42 vertically spiral be arranged at the outside of brush roll 41.Thereby, in the positive plate 3 that gathers dust, relatively rotating process, can comprehensively remove the dust of the face of gathering dust and can eliminate the dead angle that can't touch;
The second, bristle 42 comprises a plurality of bristle pack that extend to form vertically, and a plurality of described bristle pack are along circumferentially being set in turn in the outside of described brush roll 41.
Certainly, on the basis that meets deashing function and assembly technology requirement, in this programme, bristle 42 can otherwise be arranged at the outside of brush roll 41.
Finally, it is emphasized that two dust cleaning brushs 4 in this programme are positioned at the airless zone of housing 1, to avoid in deashing process occurring the reentrainment of dust problem.Be appreciated that according to actual deashing demand, the one in two dust cleaning brushs or in both all can be positioned at the flow area of housing 1
Except above-mentioned deashing mechanism, the present invention also provides a kind of electric cleaner, comprise housing, be arranged at least one the moving anode electric dust collector in described housing, described moving anode electric dust collector comprises and is moving anode, the driving mechanism that drives described moving anode to move along described loop that loop distributes and is arranged at the deashing mechanism in the airless zone, and described deashing mechanism is specially deashing mechanism as above.In view of this moving anode electric cleaner has adopted above-mentioned deashing mechanism, therefore, it also possesses the above-mentioned beneficial effect of deashing mechanism, so do not repeat them here.Be appreciated that the basic function parts that form this moving anode electric cleaner and operation principle and prior art are basic identical, those skilled in the art can realize fully based on prior art, therefore this paper repeats no more.
The foregoing is only the preferred embodiment of the present invention, do not form limiting the scope of the present invention.Any any modification of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present invention.
