Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical scheme of the invention is further explained by combining the attached drawings.
As shown in fig. 1, the blackboard eraser comprises a blackboard eraser body 1, wherein at least one opening is formed in the lower surface of the blackboard eraser body, a rotating brush 4 is arranged in the opening, and the rotating shaft of the rotating brush 4 is in the same plane with the lower surface of the blackboard eraser body. The rotating brush 4 rotates under the control of the motor, and when the brush rotates, the formed air turbine can suck chalk dust to play a role in erasing chalk marks and preventing dust from flying. Can be arranged in the blackboard eraser main body through a motor.
The blackboard eraser body 1 is internally provided with a communicated chalk dust channel 6 which comprises a transverse channel 61 arranged at the bottom of the body and a vertical channel 62 arranged at the side part of the body, and the tail end of the vertical channel, namely the top of the body, is provided with an air outlet 7. Vertical passageway top one side is equipped with the opening towards the inside direction of main part, opens this opening and is the bar, and the grey district 2 of collection at main part top is located in the opening intercommunication, and the grey district of collection is inverted triangle-shaped, and triangular lower part is equipped with locker room 5. The storage chamber 5 is of the filter screen structure 21 with the contact surface of the ash collecting area 2, and because the particle size of chalk ash is large, the chalk ash is settled under the action of gravity and falls into the storage chamber 5 through the filter screen structure 21. The top of the blackboard eraser body 1 is provided with a water inlet 10 at the position of the dust collecting area, and the water inlet is communicated with a storage chamber 5. The water inlet can also be arranged on the side wall of the blackboard eraser body 1 near the storage chamber 5.
The cylindrical through-hole structure of locker room 5 for running through the blackboard eraser main part, 5 one ends in locker room are equipped with push rod device 3, and push rod device 3 can carry out piston motion in locker room 5, and the push rod device 3 center is equipped with puddler 31. After the pusher device is pushed into the storage chamber 5, the chalk dust is mixed with the injected water by rotating the stirring rod 31. The push rod device 3 can also be provided with a micro motor for controlling the automatic rotation of the stirring rod 31. After the chalk dust is uniformly mixed, the push rod device is pulled out, the solidification time of the chalk dust is judged through the time displayed by the timing display 9, and after the chalk dust is solidified, the chalk dust is pushed into the push rod device to push the solidified chalk out of the storage chamber outlet 8. The outlet 8 of the storage chamber is also provided with a rotary shutter.
Still be equipped with weighing device in the locker room 5, weighing device connects timing display 9, shows the chalk dust weight in the locker room, judges whether locker room 5 is full of, further judges the water injection opportunity.
The air outlet 7 is provided with a filter screen or a rotary fan blade, and the motor can control the blade to rotate to form an air flow pipe for ventilation and help the chalk dust to move upwards along the vertical channel.
