Problems solved by technology
[0004] The object of the present invention is to provide a self-cleaning and angle-adjustable teaching board, which can automatically clean the content on the teaching board without manual labor, save time and energy, and can automatically adjust the angle to solve the problem. It is very difficult for people who are not tall enough to clean the top content of the teaching board, which not only wastes energy but also delays time, and the teaching board will reflect in sunny summer, causing some students to be unable to see the content of the teaching board.

Embodiment Construction
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0019] see Figure 1-4 , the present invention provides a technical solution: a self-cleaning and angle-adjustable teaching board, including a protective case 1, a U-shaped groove 7 is opened inside the protective case 1, and the cross-sectional diameter of the U-shaped groove 7 is larger than that of the blackboard 2 The diameter of the cross section, and there is a gap between the U-shaped groove 7 and the blackboard 2 to ensure that the angle of the blackbo...

The invention discloses a self-cleaning type teaching board with an adjustable angle. The self-cleaning type teaching board with the adjustable angle comprises a protection shell. A rotating mechanism is arranged at the bottom end of an inner cavity of the protection shell. A blackboard located inside the protection shell is fixedly installed on the top of the rotating mechanism. A rotating rod is fixed inside and sleeved with the blackboard, and the bottom end of the rotating rod is connected with the rotating mechanism. The two ends of the rotating rod are movably installed inside the protection shell through bearing pedestals. Drive mechanisms are arranged on the two sides of the blackboard. Through rotation of an arranged rotary motor, a first bevel gear and a second bevel gear engaged with the first bevel gear are driven to rotate, so that the blackboard fixed to the rotating rod rotates, the generated angle ingeniously prevents the situation that due to light reflection, students cannot see teaching content on the blackboard, the arranged drive mechanisms provide a power source for a cleaning mechanism so that the cleaning mechanism can be driven to move on the backboard back and forth, and accordingly the effect of automatic cleaning without manpower is achieved.
Description
technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a self-cleaning and angle-adjustable teaching board. Background technique [0002] The blackboard does not specifically refer to the black board surface. In the traditional sense, it is a flat surface that can be written repeatedly. The board surface is hard and is mostly used for teaching, also known as the teaching board. [0003] The existing teaching boards are mostly cleaned manually, either by students or teachers. It is very difficult for people who are not tall enough to clean the top content of the teaching boards, which not only wastes energy but also delays time. Some students cannot see what is on the teaching board, so we propose a self-cleaning and angle-adjustable teaching board. Contents of the invention [0004] The object of the present invention is to provide a self-cleaning and angle-adjustable teaching board, which can automatically clean the c...
