[0002] The blackboard does not specifically refer to a black board. In the traditional sense, it is a flat surface that can be written on repeatedly with chalk. The board surface is hard and is mostly used for teaching. The blackboard is generally made of wood or frosted glass. You can write on it with specific writing materials such as chalk. It is mostly black, dark green, white or beige. my country's education system mainly uses the traditional blackboard, blackboard eraser, and chalk mode for classroom teaching. Our main source of knowledge for students receiving education in school is the teacher. The hard-working teachers use the blackboard as a medium to impart knowledge to us.

[0003] However, when some existing blackboards are in use, teachers usually use chalk to write knowledge points and other content on the blackboard, resulting in a cycle of the teacher erasing and writing on the blackboard during a class.

[0044] Furthermore, the connecting component 10 includes a guide block 1001 which is slidably connected to the inside of the guide groove 8. The guide block 1001 is threadedly sleeved on the outer surface of the threaded rod 901. The guide block 1001 extends out of the inside of the guide groove 8. The outer surface of the guide block 1001 is fixedly connected with a mounting block 1002. The internal thread sleeve of the mounting block 1002 is provided with a locking bolt 1003. The outer surface of the mounting frame 5 is provided with a threaded hole that is compatible with the locking bolt 1003. The guide block 1001 can be driven to slide inside the guide groove 8 by rotating the threaded rod 901. At this time, the movement of the guide block 1001 drives the movement of the mounting block 1002. At this time, because the mounting block 1002 and the mounting frame 5 are connected by the locking bolt 1003, the mounting block 1002 can drive the mounting frame 5 and the cleaning wipe 7 inside it to move. At the same time, the setting of the locking bolt 1003 facilitates the separation of the mounting frame 5 and the connecting component 10.

[0045] Furthermore, the clamping assembly 12 includes a guide rod 1201 fixedly connected to the inside of the sliding groove 11, a sliding block 1202 is slidably sleeved on the outer surface of the guide rod 1201, the sliding block 1202 is slidably connected to the inside of the sliding groove 11, a first spring 1203 is fixedly connected between the sliding block 1202 and the inner wall of the sliding groove 11, the first spring 1203 is sleeved on the outside of the guide rod 1201, and a slot 1204 is provided on the outer surface of the sliding block 1202.

[0046] Furthermore, a first through slot 13 is formed on the upper surface of the connecting plate 6 , and a first mounting assembly 14 is disposed inside the first through slot 13 .

When the connecting plate 6 and the cleaning wipe 7 need to be disassembled, the two first driving plates 1401 are moved toward the middle. The second spring 1404 will be deformed, thereby driving the lower block 1403 to slide inside the second through groove 1402, and then the block 1403 will be disengaged from the inside of the groove 1204, and finally the connecting plate 6 and the cleaning wipe 7 will be disassembled. Through the setting of the first mounting component 14, when the cleaning wipe 7 is used for too long or is severely worn, the connecting plate 6 can be disassembled through the first mounting component 14, so that the cleaning wipe 7 can be cleaned or replaced, which makes it as convenient as possible for the user to replace or clean the cleaning wipe 7, thereby improving the flexibility of the device, thereby ensuring the cleaning effect of the cleaning wipe 7 on the writing board 2, and the operation is simple and the practicality is high.

[0048] By setting the clamping component 12, when the cleaning wipe 7 and the writing board 2 are in contact with each other, the first spring 1203 will be deformed. At this time, the elastic force of the first spring 1203 itself can push the sliding block 1202 to move, thereby ensuring that the connecting plate 6 and the cleaning wipe 7 can always be in contact with and in contact with the writing board 2, thereby ensuring the cleaning effect of the cleaning wipe 7 on the writing board 2 as much as possible.

[0049] Furthermore, two T-shaped docking blocks 15 are fixedly connected to the lower surface of the installation frame 5, and a T-shaped docking groove 16 is provided on the upper surface of the collection box 4 for sliding connection with the T-shaped docking block 15. The bottom wall of the T-shaped docking groove 16 is provided with two third through grooves 17, and a second installation component 18 is arranged inside the third through groove 17. When the staff needs to assemble the installation frame 5 and the collection box 4, the installation frame 5 and the collection box 4 can be fixed by sliding the T-shaped docking block 15 into the inside of the T-shaped docking groove 16 and then using the second installation component 18.

The movement of the second driving plate 1803 will cause the two trapezoidal blocks 1801 to slide downward inside the third through groove 17. At this time, the two trapezoidal blocks 1801 will no longer limit the T-shaped docking block 15, and the collection box 4 can be disassembled subsequently. Through the setting of the second mounting component 18, when the collection box 4 follows the cleaning wipe 7 to move up for a long time to collect chalk dust until there is a lot of chalk dust inside, the collection box 4 and the mounting frame 5 can be separated by the second mounting component 18, so as to make it as convenient as possible for the user to clean the chalk dust collected inside the collection box 4 or clean the inside of the collection box 4, thereby further improving the practicality and flexibility of the device and simplifying the operation.

[0051] Working principle:

[0052] When the blackboard wiping machine with a cleaning function is in use, the left threaded rod 901 is driven to rotate by starting the motor 902. At this time, the right threaded rod 901 can be synchronously rotated by the transmission of the belt drive assembly 904. The rotation of the threaded rod 901 drives the guide block 1001 to slide inside the guide groove 8. The movement of the guide block 1001 drives the movement of the mounting block 1002. At this time, because the mounting block 1002 and the mounting frame 5 are connected by the locking bolt 1003, the mounting block 1002 can drive the mounting frame 5 and the cleaning wipe 7 inside it to move. When the cleaning wipe 7 and the writing board 2 are against each other, the first spring 1203 will be deformed. At this time, the elastic force of the first spring 1203 can push the sliding block 1202 to move, thereby ensuring that the connecting plate 6 and the cleaning wipe 7 can always be in contact with and against the writing board 2, and the cleaning effect of the cleaning wipe 7 on the writing board 2 is guaranteed as much as possible, and finally the writing board 2 is cleaned. At the same time, the collecting box 4 will move synchronously during the movement of the mounting frame 5, and the collecting box 4 will collect the chalk dust generated by the cleaning wipe 7 wiping the writing board 2;

[0053] When the connecting plate 6 and the cleaning wipe 7 need to be disassembled, the two first driving plates 1401 are pushed toward the middle, and the second spring 1404 is deformed, thereby driving the lower clamping block 1403 to slide inside the second through groove 1402, and then the clamping block 1403 is separated from the inside of the clamping groove 1204, and finally the connecting plate 6 and the cleaning wipe 7 are disassembled;

[0054] When the collection box 4 needs to be disassembled, the two second driving plates 1803 are pressed downward, and the third spring 1804 is deformed. The movement of the second driving plates 1803 causes the two trapezoidal blocks 1801 to slide inside the third through slots 17. At this time, the two trapezoidal blocks 1801 will no longer limit the T-shaped docking block 15, and the collection box 4 can be disassembled later.

[0055] When the connection assembly 10 and the installation frame 5 need to be separated, the locking bolt 1003 can be turned;

[0056] Finally, the disassembly of the frame 1, the collecting box 4, the mounting frame 5 and the connecting plate 6 can be completed.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
