Specific embodiment
In the present embodiment, with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described roller type Dustless blackboard eraser, including blackboard eraser
Shell 2 and brush body, brush body is provided with multigroup (can be least one set), and every group includes the two cylindrical brush rollers 4 being close to side by side arrange,
The two ends of two brush roll 4 are each installed on two working gears 10 in driven gear group 9, and two working gears 10 pass through outer
Tooth engagement on circumference is it is ensured that turn to contrary；Driven gear group 9 respectively engages connection one driving gear 8, driving gear 8 and rubber tire 3
It is installed on side by side in a driving gear axial trough 12, rubber tire 3 carries driving gear 8 to engage with driven gear group 9 under external force；Hair
Brush roll, in blackboard eraser shell, is provided with gearcase 7 in blackboard eraser shell, the outer end of gearcase 7 is provided with ceiling box 1, driving tooth
Wheel 8, the main part of driven gear group 9 and rubber tire 3 are located in gearcase 7, and rubber tire 3 is a part of convex to be exposed to outside ceiling box 1；Hairbrush
Between the edge of roller 4 and blackboard eraser shell 2, setting baffle plate 5 is closed, and a part for brush roll 4 is exposed to outside baffle plate 5, baffle plate 5
The side longitudinally contacting with brush roll 4 is provided with comb 15.
Driving gear axial trough 12 is located in a gear shaft gripper shoe 14, is additionally provided with installation driven tooth in gear shaft gripper shoe 14
The driven gear axis hole 13 of wheel group 9, is respectively provided with a gear shaft gripper shoe 14 in gearcase 7；Driving gear axial trough 12 is to tilt
Structure, driving gear 8 side by side and is movably installed in high one end in driving gear axial trough with rubber tire 3, and rubber tire 3 is being acted on by external force
Driving gear 8 is driven to be snapped down to be meshed with driven gear group 9 along driving gear axial trough 12 under state.
The side that ceiling box 1 is connected with baffle plate 5 has dust mouth 11, and dust mouth 11 is provided with can be towards unidirectional in ceiling box 1
The dust mouth lid 6 opened；It is provided with the connection buckle (not shown) of detachable ceiling box between ceiling box 1 and blackboard eraser shell 2.
