Problems solved by technology

[0003] The existing traditional blackboard has a simple structure. The teacher writes all the characters on the blackboard. When it needs to be wiped, the teacher needs to wipe it manually, which affects the teacher's teaching rhythm and the thinking continuity of students' thinking, and delays the class time. The most serious is , the wiped chalk dust will fly around, causing respiratory diseases and triggering some dust-sensitive diseases, seriously affecting the health of teachers and students

Embodiment 1

[0027] The preferred embodiment of the present invention provides a segmented cleaning teaching blackboard, which includes a blackboard body 1, which is embedded in a wall, and also includes a dust-free cleaning device 2, a driving device 3, and mounting elements. The mounting element is fixed on the upper and lower sides of the blackboard body 1, the dust-free cleaning device 2 is movably connected to the driving device 3, and the driving device 3 is connected to the mounting element;

[0028] The dust-free cleaning device 2 includes a strip-shaped blackboard brush 21, a dust suction cavity 22, and a silent vacuum cleaner main body 23. The strip-shaped blackboard brush 21 is connected to the dust suction cavity 22, and the dust suction cavity 22 is connected to the silent vacuum cleaner. The main body 23 is connected by a hose, and the dust suction chamber 22 is connected with the driving device 3;

[0029] The driving device 3 includes a screw 31, a sliding rod 32, and a lifting ...

Embodiment 2

[0035] The preferred embodiment of the present invention has made the following optimizations on the basis of the first embodiment. The lifting structure 33 includes a protective shell 331, a rotating drum 332, a guide shell 333, and a lifting slider 334 for rotating and sliding. The cylinder 332 is connected with the protective shell 331 through a bearing, the guide shell 333 is fixedly installed inside the protective shell 331, the lift slider 334 is installed inside the guide shell 333, and the end of the lift slider 334 is connected to the dust suction chamber 22. The lifting slider 334 is provided with a pulley, the outer surface of the drum 332 is provided with a wave groove connecting end to end, the pulley is installed in the wave groove, and the drum 332 is connected with a driving motor.

[0036] The working principle of this embodiment: when the lifting structure 33 is required to lift, the drive motor rotates to drive the drum 332 to rotate, and the rotation of the wav...

Embodiment 3

[0038] The preferred embodiment of the present invention makes the following optimizations on the basis of the first embodiment. The section of the dust suction cavity 22 is trapezoidal, and the outer surface of the dust suction cavity 22 is provided with dust suction holes.

[0039] The working principle of this embodiment: the dust intake structure of the dust suction cavity 22 is designed as a dust suction hole, which increases the space volume of the dust suction cavity 22, and the design of the dust suction hole reduces the inside and outside of the dust suction cavity 22 The active air flow of the mute vacuum cleaner body 23 ensures that the suction power supplied to the vacuum chamber 22 of the mute vacuum cleaner body 23 is large enough to increase the dust collection effect. The trapezoidal cross-section makes it have a larger surface area than the rectangular cross-section in a limited space. Vacuum range.

The sectional cleaning type teaching blackboard adds the dust removing function besides automatically cleaning the blackboard body, and the health of teachers and students is ensured; besides, sectional cleaning is adopted, the sectional cleaning type teaching blackboard is suitable for blackboard writing styles of different teachers, and therefore the sectional cleaning type teaching blackboard has quite high popularization value.

Description

Technical field [0001] The invention belongs to the technical field of teaching equipment, and specifically relates to a segmented clean teaching blackboard. Background technique [0002] The blackboard does not specifically refer to a black board. In the traditional sense, it is a flat surface that can be written repeatedly. The board is hard and is mostly used for teaching. Made of wooden boards or frosted glass, you can write on them with chalk and other specific writing materials. Most of them are black, dark green, white or beige. The types of current blackboards have also begun to become complex and diverse. There are different colors. Blackboard, green board, white board; from the surface shape, there are flat panels, arc panels, and from the structural composition, there are bracket movable panels, push-pull panels, lifting panels, and magnetic blackboards. [0003] The existing traditional blackboard has a simple structure. The teacher writes all the fonts on the blackboa...
