Abstract
An electric dust-free blackboard eraser comprises a top cover (1), a motor (2), a battery (3), a dust absorption chamber (4), a switch (5), a fan (6), a filter chamber (7), a brush installation chamber (8) and a brush (9). Compared with the prior art, the blackboard eraser is cleaner and quicker to erase by adopting the hairbrush, and the small fan is used for absorbing dust generated by erasing the blackboard. And the dust is stored in the filter chamber by adopting the air filter device to prevent the dust from flying, and the brush part can be replaced, thereby achieving the purpose of saving.
Description
Technical Field
The invention relates to a blackboard eraser, in particular to an electric dust-free blackboard eraser, and belongs to the technical field of manufacturing of working supplies.
Background
Although science and technology are different day by day, textbook educators still work as the foundation of the nation, although PPT teaching and electronic teaching appear, the face-to-face blackboard writing mode is still the main trend, the blackboard eraser becomes an indispensable tool due to the blackboard writing, dust flying condition occurs when the existing blackboard eraser is used, and the respiratory tract safety of teachers and students is greatly influenced. Although various blackboard erasers on the market cannot prevent the diffusion of flying dust, part of dust-free blackboard erasers have the condition of large volume or incapability of using common blackboards. Therefore, it is necessary to research a new dust-free blackboard eraser.
Disclosure of Invention
The invention aims to overcome the defects and provide the electric dust-free blackboard eraser which is light and small and can prevent dust from diffusing.
The invention relates to an electric dust-free blackboard eraser which comprises a top cover, a motor, a battery, a dust absorption chamber, a switch, a fan, a filter chamber, a brush installation chamber and a brush. The top of the blackboard eraser is provided with a top cover, a dust absorption chamber is arranged below the top cover, a filter chamber is arranged below the dust absorption chamber, and a brush installation chamber is arranged below the filter chamber. A motor is arranged in the dust collection chamber. The shaft of the motor is connected with the fan. The brush is installed in the brush installation chamber. The side surface of the dust collection chamber is provided with a switch. The battery, the switch and the motor are connected through wires.
The beneficial technical effects of the invention are as follows: compared with the prior art, the blackboard eraser is cleaner and quicker to erase by adopting the hairbrush, and the small fan is used for absorbing dust generated by erasing the blackboard. And the dust is stored in the filter chamber by adopting the air filter device to prevent the dust from flying, and the brush part can be replaced, thereby achieving the purpose of saving.

Detailed Description
The structure and operation of the present invention will be described with reference to fig. 1-6.
The invention discloses an electric dust-free blackboard eraser which comprises a top cover 1, a motor 2, a battery 3, a dust absorption chamber 4, a switch 5, a fan 6, a filter chamber 7, a brush installation chamber 8 and a brush 9. The top of the blackboard eraser is provided with a top cover 1, a dust absorption chamber 4 is arranged below the top cover 1, a filter chamber 7 is arranged below the dust absorption chamber 4, and a brush installation chamber 8 is arranged below the filter chamber 7. The motor 2 is installed in the dust chamber 4. The shaft of the motor 2 is connected to a fan 6. A brush 9 is installed in the brush installation chamber 8. The switch 5 is arranged on the side surface of the dust chamber 4. The battery 3, the switch 5 and the motor 2 are connected through wires.
The blackboard eraser has two motors 2 and two fans 6.
The working process of the invention is as follows:
when the electric dust-free blackboard eraser is held by hand, the switch 5 is turned on, the battery 3 supplies power to the motor 2, and the motor 2 rotates to drive the fan 6 to rotate. In the process of erasing the blackboard, the brush 9 erases chalk marks on the blackboard, dust is sucked into the blackboard eraser by the suction force generated by the fan 6, the dust is filtered by the filter chamber 7 and collected into the filter chamber 7, and the switch 5 is closed after the blackboard eraser is erased, so that the blackboard erasing work is completed. When the dust amount in the blackboard eraser is large, the brush installation chamber 8 is opened, the filter chamber 7 is taken out, and the collected dust is collected everywhere.
Claims (2)
