The utility model provides a recoverable chalk dust blackboard eraser, the concrete design is as follows:
1) the blackboard eraser capable of recycling chalk dust is characterized in that the sponge eraser is mesh-shaped and can pass through dust, a fan is arranged behind the sponge and driven by a motor, the erased dust is sucked into the dust net during erasing, then dust is filtered out through a filter screen in an exhaust hole, and the environment that no dust flies when chalk characters are erased is achieved.
2) The dust is gathered in the outer barrel, the packing auger is driven by the motor arranged in the outer barrel, the packing auger rotates to convey the dust to the compression pipe at the tail end, and the dust is stored in the compression pipe.
3) After a certain amount of dust in the compression pipe is stored, the packing auger rotates to compress the dust, the pressure sensor which is designed and arranged in the compression pipe can be triggered, the packing auger is further driven to compress the dust, meanwhile, the heating pipe works, and the dust is compressed and heated to the pressure and the temperature which can be shaped. After the dust is shaped into new chalk, the indicator light at the tail end can display a prompt. This can remove the chalk for further use by opening the compressed cap.

Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
the utility model provides a recoverable chalk dust blackboard eraser. The blackboard eraser aims at solving the problem that dust flies when a common blackboard eraser erases chalk characters at present, which is not beneficial to the healthy environment of teachers and students. A small and energy-saving recyclable chalk dust blackboard eraser is designed;
as an embodiment of the present invention, the present invention provides a recyclable chalk dust blackboard eraser as shown in fig. 1-4, which comprises a sponge eraser 1, an outer cylinder 2, a compression tube 3, a heating tube 4, a dust suction hole 5, a switch button 6, a charging port 7, a battery 8, a dust suction fan 9, a dust suction fan motor 10, an auger motor 11, an auger motor 12, an auger motor support 13, a dust suction fan motor support 14, a compression tube cover 15, and a vent hole 16. The method is characterized in that: the sponge eraser 1 is a multi-mesh sponge, a dust absorption fan 9 is arranged inside the sponge eraser, the dust absorption fan 9 is arranged on a dust absorption fan motor 10 in the outer cylinder 2 for driving dust absorption, the dust absorption fan motor is arranged on a dust absorption fan motor support 14, when a blackboard is erased, a switch button 5 is firstly pressed, a battery 8 supplies power to the dust absorption fan motor 10, the motor starts to work to drive the dust absorption fan 9 to rotate, when the sponge eraser 1 erases chalk characters on the blackboard, dropped dust is sucked into an inner cavity of the blackboard eraser through the rotation of the fan through meshes of the sponge, dust is filtered through a filter screen of an exhaust hole 16, the dust is driven by an auger motor 11 arranged on an auger motor support 13 to drive an auger 12 arranged inside the outer cylinder 2 to rotate, the filtered dust is conveyed and compressed into a compression pipe 3, and when the compression pipe 3 detects that the inside is full of dust, the auger, after compression, the heating pipe 4 works to fix and form the dust ash. After the fixing and forming, the indicator lamp arranged on the panel prompts that the panel can be taken out. The chalk is taken out for reuse after the compression cap 15 is opened. The battery 8 in the blackboard eraser is a rechargeable battery and can be charged through the charging port 7.
