Description

Technical Field

[0001] The utility model relates to the technical field of teaching auxiliary tools, in particular to a blackboard erasing cleaning device. Background Art

[0002] Blackboard eraser is a common teaching tool. Blackboard eraser is generally made of items such as flannel sponge. During the use of blackboard eraser, flannel rubs against the blackboard to wipe the blackboard. After the blackboard eraser is used for a long time, chalk dust will accumulate on the flannel of the blackboard eraser, resulting in poor effect of cleaning the blackboard by the blackboard eraser. Therefore, the blackboard eraser needs to be cleaned, so the existing blackboard eraser cleaning device has been continuously innovated and developed. Therefore, it can be seen that the current blackboard eraser cleaning device basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the announcement number CN214865545U discloses a blackboard eraser cleaning device, which is provided with "a shell and a shell cover, the inner wall of the shell is provided with at least one vertically arranged No. 1 card slot, the center position of the shell is provided with a rotating shaft, the circumference of the rotating shaft is evenly distributed with brushes, and a dust collection box that cooperates with the shell in a drawer-like manner is provided below the No. 1 card slot. The blackboard eraser with accumulated dust is placed in the No. 1 card slot, and then the shell cover is closed. The rotating shaft is equipped with a motor, and the rotating shaft is rotated to make the brush act on the blackboard eraser, so that the dust on the blackboard eraser falls into the dust collection box, which will not cause dust to fly, thereby ensuring a good teaching environment."

[0004] However, when the above device is actually used, since the blackboard eraser goes deep into the shell and cleans in the shell, the user needs to reach into the shell to take the blackboard eraser after cleaning, which is inconvenient to take. The chalk dust floating in the shell is easy to adhere to the skin on the surface of the human body and contaminate the skin. In addition, the fallen chalk dust is easy to float in the shell at will, which is difficult to remove, resulting in a decrease in cleaning efficiency. Therefore, a blackboard eraser cleaning device is urgently needed to solve the above problems. Utility Model Content

[0027] When cleaning the blackboard eraser body 4, the blackboard eraser body 4 is placed in the placement frame 1, and then the motor 5 is turned on. Then the motor 5 drives the rotating shaft 6 to rotate, and then the rotating shaft 6 drives the extrusion block 3 to rotate, and then the extrusion block 3 contacts the blackboard eraser body 4, and then pushes the blackboard eraser body 4 to move right, and then the blackboard eraser body 4 pushes the connecting plate 8 to move right, thereby squeezing the spring 7, and the blackboard eraser body 4 hits the fixed plate 2, and then the extrusion block 3 continues to rotate and moves away from the blackboard eraser body 4, and at the same time the spring 7 pushes the connecting plate 8 to move left, and then the connecting plate 8 pushes the blackboard eraser body 4 Move leftward along the surface of the baffle 15 to reset it, and do this repeatedly, knock the blackboard eraser body 4 many times, so that the dust attached to the surface of the blackboard eraser body 4 falls into the placement frame 1, so as to achieve the purpose of cleaning the blackboard eraser body 4. At the same time, the rotating shaft 6 drives the first gear 9 to rotate, thereby pushing the blackboard eraser body 4 to move upward, so that it is exposed to the outside of the placement frame 1, which is convenient to use. The device places the blackboard eraser body 4 inside the placement frame 1 and closes the upper cover 19 to avoid chalk dust floating indiscriminately during the process of knocking and cleaning the blackboard eraser body 4, thereby polluting the surrounding environment.

[0028] Furthermore, a protection frame 16 is fixedly installed on the inner wall of the placement frame 1, a collection frame 17 is placed on the inner wall of the placement frame 1, and a sealing cover 20 is rotatably connected to the back of the placement frame 1;

[0029] The protective frame 16 can prevent chalk dust from falling into the first gear 9 and the second gear 10, which increases the difficulty of cleaning. The falling chalk dust is collected by the collecting frame 17, and then the sealing cover 20 is opened and the collecting frame 17 is taken out, which facilitates the centralized treatment of the chalk dust and improves the convenience of cleaning.

[0030] See also Figure 3-5 , an embodiment provided by the utility model:

[0031] The outer surface of the first gear 9 is meshedly connected with the second gear 10, the inner wall of the second gear 10 is fixedly installed with a threaded rod 11, and the threaded rod 11 is rotatably connected to the inner wall of the placement frame 1, and the outer surface of the threaded rod 11 is provided with a pushing assembly, which includes a moving block 12 and a push plate 13, the moving block 12 is threadedly connected to the outer surface of the threaded rod 11, the push plate 13 is fixedly connected to the top of the moving block 12, the push plate 13 is trapezoidal block-shaped, and the push plate 13 is located below the blackboard eraser body 4, the inner wall of the moving block 12 is embedded with a connecting rod 18, and the connecting rod 18 is fixedly connected to the top of the protective frame 16;

[0032] When the first gear 9 rotates, the first gear 9 pushes the second gear 10 to rotate, and then the second gear 10 drives the threaded rod 11 to rotate, so that the pushing assembly moves upward along the outer surface of the threaded rod 11, and then pushes out the blackboard eraser body 4, which is convenient for use. When the threaded rod 11 rotates, the threaded rod 11 drives the moving block 12 to rotate, and then the moving block 12 is resisted by the connecting rod 18, so that the moving block 12 moves upward along the outer surface of the threaded rod 11, and then the moving block 12 pushes the push plate 13 to move upward, and then the push plate 13 pushes the blackboard eraser body 4 to move upward, so that it is away from the placement frame 1, and the blackboard eraser body 4 is exposed to the outside, which is convenient for taking the blackboard eraser body 4, and the push plate 13 is in a trapezoidal block shape, which can guide the fallen chalk dust to flow into the collection frame 17, to prevent the chalk dust from being scattered everywhere in the placement frame 1, causing inconvenience in cleaning.

[0033] Furthermore, a fixing frame 14 is provided on the inner wall of the placement frame 1, and a baffle 15 is provided on the bottom of the fixing frame 14;

[0034] The blackboard eraser body 4 is supported by the fixing frame 14 and the baffle 15 so as to move within the baffle 15 .

[0035] Working principle: by placing the blackboard eraser body 4 into the placing frame 1, then turning on the motor 5 to drive the rotating shaft 6 to rotate, and then driving the extrusion block 3 to rotate, the extrusion block 3 gradually approaches the blackboard eraser body 4 and pushes the blackboard eraser body 4 to move to the right, then the blackboard eraser body 4 squeezes the spring 7 through the connecting plate 8, and then the blackboard eraser body 4 hits the fixed plate 2, so that the dust attached to the blackboard eraser body 4 falls down, and then rolls down along the push plate 13 to the collection frame 17 for centralized collection, which is convenient for cleaning, thereby improving the cleaning efficiency, and repeating this process, repeatedly hitting the blackboard eraser body The body 4 improves the cleaning effect of the blackboard eraser body 4. At the same time, the rotating shaft 6 drives the first gear 9 to rotate, and then drives the second gear 10 to rotate, and then drives the moving block 12 to move upward along the outer surface of the connecting rod 18 through the threaded rod 11, and then drives the push plate 13 to move upward, thereby pushing the blackboard eraser body 4 to move upward, so that it is exposed to the outside of the placement frame 1, which is convenient for taking, and in the cleaning process, the upper cover 19 is closed to avoid the situation where chalk dust floats wantonly and pollutes the surrounding environment. The device uses the same motor 5 to achieve the purpose and saves energy.
