Described shell is also provided with removable shell, and removable shell is connected with adopting interference fit between shell, and the upper end of motor shaft is fixedly connected on bottom removable shell.
The rotating ratio of described dust absorption fan and bristle brush wheel is 9:1.
The gearratio of described first gear and the second gear is 3:5, and the gearratio of the 3rd gear and bristle brush wheel is 15:1.
The rear portion of described outer casing bottom is provided with fixed hairbrush.
The beneficial effects of the utility model: structure is simple, and volume is little, and efficiency is high, and pick-up performance is good, easy to carry, practical, for convenience detach and cost is low.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 is the partial sectional view of Fig. 1;
Wherein: 1-shell, the removable shell of 2-, 3-motor, 4-bristle brush wheel, 5-dust absorption fan, 6-first axle, 7-motor shaft, 8-first gear, 9-second gear, 10-the 3rd gear, 11-hairbrush, 12-control of dust ring, 13-gas outlet, 14-battery, the fixed hairbrush of 15-, 16-clutch shaft bearing, 17-second bearing, 18-the 3rd bearing.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details: as shown in Fig. 1 ~ Fig. 2, a kind of blackboard surface cleaning device, comprise shell 1, dust absorption fan 5, motor 3 and there is the bristle brush wheel 4 of air vent, described motor 3 is fixing shaft type motor, the upper end of motor shaft 7 is fixedly connected on bottom removable shell 2, the lower end of motor shaft 7 is connected by clutch shaft bearing 16 with bristle brush wheel 4 center, removable shell 2 adopts interference fit to be connected with between shell 1, the top fixed cover of the shell of motor 3 is equipped with the first gear 8, and bottom fixed cover is equipped with dust absorption fan 5, the second gear 9 is also provided with in shell 1, described second gear 9 is meshed with the first gear 8, second gear 9 is fixedly set on the first axle 6, first axle 6 is arranged in shell 1 by the second bearing 17 and the 3rd bearing 18, wherein, second bearing 17 is arranged on the top of the first axle 6, 3rd bearing 18 is arranged on the middle part of the first axle 6, in the bottom of the first axle 6, also fixed cover is equipped with the 3rd gear 10, the edge of described bristle brush wheel 4 is provided with the gear teeth, described 3rd gear 10 is meshed with the gear teeth at bristle brush wheel 4 edge, the bottom of described bristle brush wheel 4 is provided with some row's hairbrush 11, there is control of dust ring 12 in the outer setting of dust absorption fan 5, in control of dust ring 12, be provided with filter screen, shell 1 side is provided with the gas outlet 13 corresponding with control of dust ring 12, two electrodes of motor 3 are in series with battery 14 and soft-touch control, and battery 14 is arranged in shell 1, and soft-touch control is arranged on shell 1 outer surface.
When the clean blackboard of needs, first gently soft-touch control is touched, motor 3 is made to start to rotate, motor 3 is fixing shaft type motor, motor housing can drive dust absorption fan 5 to rotate, and the first gear 8 also can rotate simultaneously, drives the second gear 9 to rotate further, second gear 9 drives the 3rd gear 10 to rotate by the first axle 6, and the 3rd gear 10 drives bristle brush wheel 4 to rotate by the gear teeth on bristle brush wheel 4.Hairbrush 11 is adjacent to blackboard, gets final product automatic-cleaning backboard, period dust absorption fan 5 dust can be sucked and pass through the strainer filtering in control of dust ring 12, be then stored in control of dust ring 12, air can flow out from gas outlet 13 and can not to environment.
The gearratio of described first gear 8 and the second gear 9 is 3:5,3rd gear 10 is 15:1 with the gearratio of bristle brush wheel 4, because the first gear 8 is identical with dust absorption fan 5 rotating speed, second gear 9 is identical with the 3rd gear 10 rotating speed, therefore dust absorption fan 5 is 9:1 with the rotating ratio of bristle brush wheel 4, through experiment, rotating ratio is that 9:1 both can ensure that the efficiency that hairbrush 11 erases the board in turn ensure that dust absorption fan 5 can by the dust collection of the overwhelming majority.
Rear portion bottom shell 1 is provided with fixed hairbrush 15, may be used for manually removing writing specifically, among a small circle on blackboard.
When dust collection is to time a certain amount of, hold tight shell 1 for one, another hand promotes removable shell 2 downwards, the bristle brush wheel 4 that the first gear 8 that related for removable shell 2 motor 3 and motor 3 shell connect, dust absorption fan 5, motor shaft 7 lower end connect can be released below shell 1, then can clean the dust in control of dust ring 12.When all dust clean totally, according to contrary method, removable shell 2, motor 3, first gear 8, dust absorption fan 5 and bristle brush wheel 4 are installed back shell 1 and can continue to use.
