Detailed ways

The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, and this embodiment does not constitute a limitation to the present invention.

An ultrasonic cleaning dust-free blackboard, as shown in FIG. 1, includes a blackboard frame 2, a blackboard 1, and a dust removal device 3. The blackboard 1 is fixedly installed on the blackboard frame 2. The blackboard 1 can slide up and down, guide rails are installed on the upper and lower sides of the blackboard frame 2, and the dust removal device 3 moves along the guide rails.

As shown in FIG. 2 , the main body of the dust removal device 3 is a rectangular parallelepiped, and the lower end of the dust removal device 3 is installed with driving wheels 4 . There are two driving wheels 4 , and the driving wheels 4 are arranged in a vertical direction. To be stable, a driven wheel 5 is installed on the upper end of the dust removal device, the setting direction of the driven wheel 5 is horizontal, and the driving wheel 4 is driven by a motor.

3 and 4 are schematic diagrams of the structure of the dust removal device, the dust removal device is provided with an opening on the side close to the blackboard, the air vents 6 are provided on both sides of the opening, and the ultrasonic sounder 7 is installed in the middle, and the air vents 6 on both sides are provided. It is connected with the exhaust fan, the exhaust fan 10 and the ultrasonic generator 7 are all connected with the battery 9, the battery 9 is also connected with the motor and the exhaust fan 10, and the battery charging port is a magnetic charging female port, so The magnetic charging main port is located on the side wall of the dust removal device 3, the left side of the blackboard frame 2 is provided with a magnetic charging main port corresponding to the magnetic charging port, and the dust removal device 3 goes from the left to the right and then back to the left.
