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.
The working principle of the application is as follows:
