Description

Technical Field

[0001] This utility model relates to the field of writing board technology, and in particular to an easy-to-clean writing board. Background Technology

[0002] In modern teaching, office, and meeting settings, whiteboards serve as a core tool for information transmission, and their cleaning efficiency directly impacts work efficiency. Traditional cleaning methods rely on manual wiping, which is not only time-consuming and labor-intensive but also prone to generating dust during the cleaning process, leading to localized increases in PM2.5 concentrations up to 300 μg / m³. 3 The above pose risks to the user's respiratory health.

[0003] Most mainstream writing board cleaning devices currently use a one-way scraper structure. Their typical design includes a slide rail fixed to the side of the board and a manually draggable cleaning scraper. Users pull the scraper horizontally to remove pen marks from the board surface through physical scraping. However, manual intervention is still required in the cleaning process. These devices usually have blind spots and are difficult to effectively control dust dispersion.

[0004] Existing cleaning systems suffer from serious secondary dust pollution. During the scraping process, chalk dust escapes from both sides of the scraper. Traditional single-scraper structures will carry the accumulated dust back out of the dust collection trough on the return trip, causing cross-contamination of the writing area. Therefore, a wound dressing and care rack is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-clean writing board, which aims to improve the problem that chalk dust will escape from both sides of the scraper during the scraping process, and the traditional single scraper structure will bring the accumulated dust back out of the dust collection tank on the return trip, causing cross-contamination of the writing area.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an easy-to-clean writing board, comprising a writing board body, a connecting block fixedly connected to the outer wall of the writing board body, a sliding block fixedly connected to the outer wall of the connecting block, a support block slidably connected to the outer wall of the sliding block, a support plate fixedly connected to the lower surface of the support block, a motor fixedly connected inside the connecting block, a gear fixedly connected to the output end of the motor, a slide rail fixedly connected to the inner wall of the connecting block, and a sliding component provided on the inner wall of the connecting block;

[0007] The sliding assembly includes a second sliding block, a rack, and a scraper. The outer wall of the second sliding block is slidably connected to the inner wall of the first connecting block. The outer wall of the rack is fixedly connected to the inner wall of the second sliding block. The outer wall of the scraper is fixedly connected to the inner wall of the second sliding block. The inner wall of the second sliding block is slidably connected to the outer wall of the slide rail. The first gear is meshed with the outer wall of the rack. A fan is provided on the outer wall of the first connecting block, and a dust collection assembly is provided at the output end of the fan.

[0008] Furthermore, the dust collection assembly includes pipe three, a collection box, pipe one, and pipe two. One end of pipe three is fixedly connected to the output end of the fan. The inner wall of the collection box is fixedly connected to the outer wall of pipe three. The outer wall of pipe one is fixedly connected to the inner wall of the collection box. The outer wall of pipe two is fixedly connected to the inner wall of pipe one. The outer walls of pipe one and pipe two are both fixedly connected to the inner wall of connecting block one.

[0009] Furthermore, a second connecting plate is fixedly connected to the lower surface of the collection box, and the outer wall of the second connecting plate is fixedly connected to the inner wall of the first connecting block.

[0010] Furthermore, a support block two is fixedly connected to the outer wall of the connecting block one, and a connecting plate one is fixedly connected to the outer wall of the support block two.

[0011] Furthermore, a sliding block three is fixedly connected to the lower surface of the connecting plate, and the outer wall of the sliding block three is slidably connected to the inner wall of the connecting frame.

[0012] Furthermore, a fixing block one and a fixing block two are fixedly connected to the upper surface of the support plate. A motor two is fixedly connected to the inner wall of the fixing block two. A connecting rod three is fixedly connected to the output end of the motor two. A gear three is fixedly connected to the outer wall of the connecting rod three. The outer wall of the connecting rod three is rotatably connected to the inner wall of the fixing block one.

[0013] Furthermore, a connecting rod is rotatably connected to the inner wall of the fixed block, and a gear is fixedly connected to the outer wall of the connecting rod. The gear and the outer walls of the gear mesh with each other.

[0014] Furthermore, a connecting block two is fixedly connected to the outer wall of the connecting rod one, a connecting rod two is slidably connected to the inner wall of the connecting block two, and the outer wall of the connecting rod two is fixedly connected to the inner wall of the sliding block three.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, a motor drives a gear to rotate, causing a rack to slide a sliding block on a slide rail. The sliding block then drives a scraper to slide on the writing board body. Symmetrical scrapers are provided on both sides of the writing board body. The two scrapers slide towards the center to clean the writing board body. The dust that falls off after cleaning is collected and processed by a dust collection component to prevent dust from flying around, effectively improving the usage environment and avoiding respiratory health hazards and equipment pollution caused by dust.

[0017] 2. In this utility model, the motor 2 drives the connecting rod 3 and the gear 3 to rotate, which in turn drives the gear 3 to rotate the gear 2 and the connecting rod 1. This causes the connecting block 2 to slide within the sliding block 3, which in turn slides the sliding block 3 upward within the connecting frame. This causes the connecting plate 1 and the support block 2 to slide, thereby adjusting the height of the connecting block 1 and the writing board body. This allows for quick adaptation to the operating needs of users of different heights, effectively solving the pain points of traditional writing boards having fixed height and poor applicability.

[0027] The sliding assembly includes a second sliding block 18, a rack 17, and a scraper 20. The outer wall of the second sliding block 18 is slidably connected to the inner wall of the first connecting block 2. The second sliding block 18 connects the rack 17 and the scraper 20, serving as a transmission hub to drive the scraper 20 to move on the surface of the writing board body 1. The outer wall of the rack 17 is fixedly connected to the inner wall of the second sliding block 18, and the outer wall of the scraper 20 is fixedly connected to the inner wall of the second sliding block 18. The scraper 20 is symmetrically installed on both sides of the writing board body 1 and slides towards the center under the action of the second sliding block 18 to remove pen marks and stains from the board surface. The inner wall of the second sliding block 18 is slidably connected to the outer wall of the slide rail 19. The gear 16 and the outer wall of the rack 17 are connected to each other. The components are interlocked and connected. A fan 13 is installed on the outer wall of the connecting block 12. A dust collection component is installed at the output end of the fan 13. The dust collection component includes a pipe 3 14, a collection box 12, a pipe 1 4, and a pipe 2 6. One end of the pipe 3 14 is fixedly connected to the output end of the fan 13. The inner wall of the collection box 12 is fixedly connected to the outer wall of the pipe 3 14. The collection box 12 is used to store the dust collected by the fan 13. It can slide to facilitate regular cleaning and maintain the dust collection function. The outer wall of the pipe 1 4 is fixedly connected to the inner wall of the collection box 12. The outer wall of the pipe 2 6 is fixedly connected to the inner wall of the pipe 1 4. The outer walls of both the pipe 1 4 and the pipe 2 6 are fixedly connected to the inner wall of the connecting block 12.

[0028] Reference Figures 1-5A connecting plate 15 is fixedly connected to the lower surface of the collection box 12. The outer wall of the connecting plate 15 is fixedly connected to the inner wall of the connecting block 2. A support block 7 is fixedly connected to the outer wall of the connecting block 2. The support block 7 is linked with the connecting plate 8. During height adjustment, it assists in supporting the writing board body 1, sharing the load-bearing pressure, and enhancing structural stability. A connecting plate 8 is fixedly connected to the outer wall of the support block 7. A sliding block 21 is fixedly connected to the lower surface of the connecting plate 8. The sliding block 21 slides vertically within the connecting frame 10, connecting the connecting block 22 and the connecting plate 8, and transmitting the power for height adjustment. The outer wall of the sliding block 21 is slidably connected to the inner wall of the connecting frame 10. A fixing block 23 and a fixing block 30 are fixedly connected to the upper surface of the support plate 9. A motor 26 is fixedly connected to the inner wall of the fixing block 30. The output end of the motor 26 is fixedly connected to... Connecting rod 3 29, gear 3 28 is fixedly connected to the outer wall of connecting rod 3 29, and the outer wall of connecting rod 3 29 is rotatably connected to the inner wall of fixed block 1 23. Fixed block 1 23 restricts the rotation trajectory of connecting rod 3 29 and connecting rod 1 24 to prevent movement deviation and ensure the stability of the height adjustment structure. Connecting rod 1 24 is rotatably connected to the inner wall of fixed block 1 23. Gear 2 25 is fixedly connected to the outer wall of connecting rod 1 24. Gear 2 25 and gear 3 28 are meshed with each other. Connecting block 2 22 is fixedly connected to the outer wall of connecting rod 1 24. Connecting rod 2 27 is slidably connected to the inner wall of connecting block 2 22. Connecting rod 2 27 pushes connecting block 2 22 upward, converting the power of motor 2 26 into the vertical movement of sliding block 3 21, realizing the height adjustment of the writing board. The outer wall of connecting rod 2 27 is fixedly connected to the inner wall of sliding block 3 21.

[0029] Working principle: When the writing board needs cleaning, the motor 11 inside the connecting block 2 starts, and the output shaft drives the gear 16 to rotate. The gear 16 meshes tightly with the rack 17, converting the rotational motion into linear motion, driving the sliding block 18 to slide smoothly along the slide rail 19. The sliding block 18 acts as a transmission hub, driving the scraper 20 mounted on it to move laterally on the surface of the writing board body 1. Thanks to the scrapers 20 symmetrically arranged on both sides of the writing board body 1, the two scrapers 20 slide towards the middle simultaneously during cleaning, thoroughly removing pen marks and stains from the board surface. The dust generated during the cleaning process is collected by the fan 13 on the connecting plate 2. After the fan 13 starts, it generates suction, and the dust is quickly sucked into the collection box 12 through the pipe 3 14 fixedly connected to it. At the same time, the ventilation slot on the connecting block 2 also plays a role, guiding the residual dust through the pipe 2 6 and the pipe 4 in sequence, and finally into the collection box 12, ensuring that there is no dust flying around during the cleaning process.

[0030] In addition, to meet the needs of users of different heights, the writing board is designed with a height adjustment structure. The fixing block 2 30 on the support plate 9 firmly fixes the motor 26. When the motor 26 is running, it drives the connecting rod 3 29 and the gear 3 28 to rotate synchronously. The gear 3 28 drives the gear 2 25 and the connecting rod 1 24 to rotate through meshing transmission. The fixing block 1 23 restricts the movement trajectory of the connecting rod 3 29 and the connecting rod 1 24 to ensure the stability of the rotation process. Under the transmission action, the connecting block 2 22 slides up and down in the sliding block 3 21. The connecting rod 2 27 pushes the connecting block 2 22 to move upward, which in turn drives the sliding block 3 21 to slide vertically in the connecting frame 10. This action synchronously drives the connecting plate 1 8 and the support block 2 7 to move upward, while the sliding block 1 3 slides in the support block 1 5. Finally, the height of the connecting block 1 2 and the writing board body 1 is adjusted to adapt to the operating needs of different users.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
