[0002] A blackboard is a traditional teaching tool with a hard, flat surface as its core. Originally made of wood or frosted glass, its surface was coated with black, dark green, or other paints to support repeated writing with chalk. However, with the advancement of technology, a single blackboard can no longer meet teaching needs. A multi-functional blackboard is an innovative teaching tool that integrates traditional writing with smart technology. Through touch interaction, multimedia integration, and cloud resource integration, it achieves a comprehensive improvement in teaching efficiency and experience. Common multi-functional blackboards use a display screen in conjunction with the blackboard for teaching. However, when erasing chalk marks, a large amount of chalk dust can contaminate the display screen, affecting its normal display.

[0003] A search revealed a Chinese patent publication number CN222089940U, which discloses a multifunctional electronic blackboard, including a protective cover, a protective plate, and a driving component. In use, the protective plate is opened, and the driving component rotates to move the frame within the protective cavity.

[0004] To address the problem of the aforementioned technologies lacking a way to prevent chalk dust from spreading and adhering to the electronic screen from one side of the blackboard, a multifunctional blackboard is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-4As shown, a multifunctional blackboard includes a mounting frame 1. A display screen 4 and a fixed blackboard 7 are fixedly connected to one side of the mounting frame 1. A cleaning component is slidably connected to one side of the mounting frame 1. An air intake 5 is fixedly connected to the middle of the mounting frame 1. The air intake 5 is fixedly connected to both sides between the display screen 4 and the fixed blackboard 7. A ventilation pipe 14 is fixedly connected to the air outlet of the air intake 5. An air outlet 16 is fixedly connected to one end of the ventilation pipe 14. Multiple silent fans 17 are fixedly connected to the inside of the air outlet 16. The air outlet of the air outlet 16 faces the host end of the display screen 4.

[0030] When a large amount of dust is generated, such as when wiping the blackboard, the silent fan 17 on the side of the air outlet 16 can be turned on. This allows air to be drawn from the air intake 5 side. When drawing air, the chalk dust floating from the blackboard on the other side can be guided and drawn into the ventilation pipe 14, preventing the chalk dust from continuing to float and adhere to the screen of the display screen 4.

[0031] At the same time, the silent fan 17 blows air, which can cause the airflow to blow towards the host part behind the display screen 4, thus cooling down the display screen 4.

[0032] The cleaning assembly includes a cleaning bracket 21, an electric roller 22, a cleaning cotton 23, and a sliding table 20. The cleaning bracket 21 is fixedly connected to the two sides of the sliding table 20, and the upper and lower sliding tables 20 are slidably connected to the corresponding side of the movable blackboard 2. The fixed end of the electric roller 22 is bolted to the cleaning bracket 21, and the inner side of the cleaning cotton 23 is fixedly connected to the rotating end of the electric roller 22.

[0033] After prolonged use, dust will inevitably accumulate on the surface of the display screen 4. At this time, the cleaning bracket 21 can be pulled out to allow the cleaning cotton 23 to clean the surface of the display screen 4. At the same time, the electric roller 22 can be started to drive the outer cleaning cotton 23 to roll, thereby improving the cleaning effect. After cleaning, the cleaning cotton 23 can be pushed back into the mounting frame 1 for storage.

[0034] In this embodiment, a filter element 15 is bolted to the inside of the ventilation pipe 14. The filter element 15 can collect and filter dust to prevent dust from spreading. It can also be replaced by removing the screws.

[0035] In this embodiment, the mounting frame 1 has grooves 3 on the upper and lower sides, and a movable blackboard 2 is slidably connected to the inner side of the grooves 3. The movable blackboard 2 can be moved in front of the display screen 4 to obtain a larger writing area, while protecting the display screen 4 from accidental damage.

[0036] In this embodiment, a water tank 11 and a water pump 18 are fixedly connected to one side of the cleaning bracket 21. The water outlet of the water tank 11 is fixedly connected to the water inlet of the water pump 18. The water outlet of the water pump 18 is fixedly connected to a cleaning spray pipe 19 through a pipe. The cleaning spray pipe 19 is fixedly connected to the inside of the cleaning bracket 21. A scraper 24 is fixedly connected to one side of the cleaning bracket 21. One end of the scraper 24 is attached to the cleaning cotton 23.

[0037] The water pump 18 is a small model that can draw water from the water tank 11 and then spray it out from the cleaning nozzle 19. The cleaning nozzle 19 is wide enough to cover the display screen 4. Together with the rotating cleaning cotton 23, it can achieve a better screen cleaning effect. The scraper 24 can scrape and clean the rotating cleaning cotton 23.

[0038] In this embodiment, a water injection hole 12 is fixedly connected to the top of the water tank 11, and a rope 10 is fixedly connected to one side of the water tank 11. The water injection hole 12 facilitates the addition of screen cleaning fluid from above.

[0039] In this embodiment: when a large amount of dust is generated when wiping the blackboard, the silent fan 17 on one side of the air outlet 16 can be turned on. This allows air to be drawn from the air intake 5 side. When drawing air, the chalk dust floating from the blackboard on the other side can be guided and drawn into the ventilation pipe 14, preventing the chalk dust from continuing to float and adhere to the screen of the display screen 4.

[0040] At the same time, the silent fan 17 blows air, which can cause the airflow to blow towards the host part behind the display screen 4, thus cooling down the display screen 4.

[0041] After prolonged use, dust will inevitably accumulate on the surface of the display screen 4. At this time, the cleaning bracket 21 can be pulled out to allow the cleaning cotton 23 to clean the surface of the display screen 4. At the same time, the electric roller 22 can be started to drive the outer cleaning cotton 23 to roll, thereby improving the cleaning effect. After cleaning, the cleaning cotton 23 can be pushed back into the mounting frame 1 for storage.

[0042] The filter element 15 can collect and filter dust to prevent dust from spreading. It can also be replaced by removing the screws. The water pump 18 can draw water from the water tank 11 and then spray it out from the cleaning nozzle 19. The cleaning nozzle 19 is wide enough to cover the display screen 4. With the rotating cleaning cotton 23, it can achieve a better screen cleaning effect. The water injection hole 12 makes it easy to add screen cleaning fluid from above.

[0043] Example 2:

[0044] A multifunctional blackboard, this embodiment is based on embodiment 1 with the following improvements, such as... Figure 1-4 As shown,
