[0043] Reference Figure 1-Figure 9 , This embodiment provides a multifunctional drawing device for architectural design students, including a drawing table 1, at least two rotating mechanisms, a drawing board 3 and a cleaning mechanism;

[0044] The rotating mechanism is movably connected to the drawing table 1, and the rotating mechanism is rotatably connected to the drawing board 3, and the rotating mechanism is used to adjust the inclination angle of the drawing board 3;

[0045] The cleaning mechanism includes a mounting frame 40, a sliding component 41 and a cleaning component 42. The mounting frame 40 is arranged on the drawing board 3. The sliding component 41 is slidably connected to the mounting frame 40, and the sliding component 41 is connected to the cleaning component 42. The cleaning component 42 is in contact with the drawing board 3. The cleaning component 42 is driven to move accordingly by the up and down movement of the sliding component 41, so that the cleaning component 42 is used to clean the drawing board 3.

[0046] In the above embodiment, the multifunctional drawing device for architectural design students comprises a drawing table 1, at least two rotating mechanisms, a drawing board 3 and a cleaning mechanism, wherein the rotating mechanism, the drawing board 3 and the cleaning mechanism are preferably two, respectively, and the two rotating mechanisms, the two drawing boards 3 and the two cleaning mechanisms are symmetrically arranged. The drawing table 1 is the basic support part of the entire drawing device, providing a stable installation foundation for other components, and its surface is usually a plane for placing components such as the drawing board 3; the rotating mechanism is movably connected to the drawing table 1, and can move within a certain range on the drawing table 1, and is rotatably connected to the drawing board 3 at the same time, and the inclination angle of the drawing board 3 is adjusted by the rotating mechanism. The inclination angle of the drawing board 3 is adjustable to meet different painting needs, without Whether drawing a sketch, a plane drawing or a three-dimensional drawing, the painter can find the most comfortable drawing angle to improve the accuracy and efficiency of drawing; there are at least two drawing boards 3, which are symmetrically arranged on the drawing table 1 through a rotating mechanism. The drawing board 3 is the main plane for drawing operations, and its surface material is suitable for the use of drawing tools, such as pencils, rulers, etc., on which lines, graphics, etc. are drawn. A specified gap is set between the drawing board 3 and the drawing table 1. On the one hand, this gap ensures that the drawing board 3 can rotate smoothly, and on the other hand, it also provides space for the sliding of the rotating mechanism. A specified interval can be formed between adjacent drawing boards 3. The width of the interval is related to the arc length of the rotation of the drawing board 3 driven by the rotating mechanism to prevent the drawing boards 3 from colliding with each other during the rotation process.

[0047] The cleaning mechanism includes a mounting frame 40, a sliding component 41 and a cleaning component 42. The mounting frame 40 is fixedly arranged on the drawing board 3 to provide an installation position for the sliding component 41 and the cleaning component 42. The sliding component 41 is slidably connected to the mounting frame 40, and the sliding component 41 is connected to the cleaning component 42. At the same time, the cleaning component 42 is in contact with the drawing board 3. The cleaning component 42 is driven to move accordingly by the up and down movement of the sliding component 41, so that the cleaning component 42 can clean the dust on the drawing board 3 and the debris generated by the painting. When the painter needs to adjust the angle of the drawing board 3, he manually holds the drawing board 3 and applies a torque. The drawing board 3 rotates around the rotating shaft 20 according to the rotating action of the rotating mechanism, thereby adjusting the tilt angle until it reaches an angle suitable for painting. If painting tools are to be placed, one of the drawing boards 3 is rotated to be horizontal with the drawing table 1. At this time, the painting tools can be placed inside the horizontal drawing board 3 for easy access. After the drawing board 3 is used, if it needs to be cleaned, the connecting rod 414 of the cleaning mechanism is manually slid to drive the sliding block 411 to slide up and down on the fixed vertical rod 410. The movement of the sliding block 411 is transmitted to the rotating rod 420 through the connecting plate 412, so that the first cleaning brush 422 on the cleaning roller 421 produces relative movement with the inner wall of the drawing board 3 and rotates due to friction, thereby cleaning the dust and debris on the inner wall of the drawing board 3. The entire cleaning process does not require the aid of other external cleaning tools, and the operation is simple and convenient.

[0048] Therefore, by setting up the cleaning component 42, when it is necessary to clean the drawing board 3, there is no need to look for additional cleaning tools. The cleaning component 42 can be driven by the sliding component 41 to move up and down on the mounting frame 40, so that the cleaning component 42 can clean the drawing board 3, which greatly simplifies the cleaning process and saves the time spent by the staff to clean the drawing board 3, thereby effectively improving the work efficiency of the staff using the drawing board 3 for architectural design drawing, while reducing the contact opportunity between the drawing tools and dust particles, and reducing the risk of damage to the drawing tools due to dust wear, thereby helping to extend the service life of the drawing tools and saving the cost of frequent replacement of the drawing tools. In addition, during the drawing process, there will be no uneven lines or uneven color adhesion due to the interference of dust, which helps to improve the quality of architectural design drawings and enable design ideas to be more accurately and clearly expressed through drawings.

[0049] Reference Figure 1-Figure 5In one embodiment, a slide groove 6 corresponding to the rotating mechanism is provided on the drawing table 1, and a specified gap is set between the drawing board 3 and the drawing table 1, the rotating mechanism is located in the slide groove 6 and is slidably connected to the drawing table 1, and the rotating mechanism slides a specified distance in the slide groove 6 to form a specified interval between the relative drawing boards 3, and the width of the specified interval is greater than or equal to the arc length of the drawing board 3 driven by the rotating mechanism to rotate, wherein the arc length is the arc length formed by the drawing board 3 rotating from perpendicular to the drawing table 1 to the drawing board 3 being horizontal to the drawing table 1.

[0050] In the above embodiment, a slide groove 6 corresponding to the rotating mechanism is provided on the drawing table 1. The slide groove 6 is a track structure specially designed for the rotating mechanism. Its shape matches the connecting part of the rotating mechanism. It is usually a long strip-shaped groove with a certain depth and width, which is used to guide the rotating mechanism to slide smoothly on the drawing table 1 and limit the moving direction of the rotating mechanism so that it can only slide along the direction of the slide groove 6; the specified gap is the space reserved between the drawing board 3 and the drawing table 1. Its function is to ensure that the drawing board 3 can rotate smoothly around the rotating mechanism and to provide necessary space for the sliding of the rotating mechanism on the drawing table 1 so that the rotating mechanism is not hindered when driving the drawing board 3 to move. The rotating mechanism is located in the slide groove 6 and is slidably connected to the drawing table 1. The specified interval is a space of a specific width formed between the two opposite drawing boards 3, and its width is greater than or equal to the arc length formed by the rotating mechanism driving the drawing board 3 to rotate from perpendicular to the drawing table 1 to horizontal to the drawing table 1, ensuring that the two opposite drawing boards 3 will not collide with each other during the process of adjusting the inclination angle of the drawing board 3 by the rotating mechanism, thereby ensuring the stability and reliability of the operation of the device.

[0051] After the initial installation of the drawing device is completed, the drawing board 3 is connected to the drawing table 1 through the rotating mechanism, and the rotating mechanism is located in the slide groove 6 of the drawing table 1. There is a specified gap between the drawing board 3 and the drawing table 1, and a certain distance is maintained between adjacent drawing boards 3 (the two opposing drawing boards 3 in the initial state do not form a specified interval); when it is necessary to adjust the position of the drawing board 3 for drawing or other operations, the rotating mechanism is manually pushed to slide in the slide groove 6. If a specified interval is to be formed between adjacent drawing boards 3, the two adjacent rotating mechanisms can be slid in opposite directions respectively. At this time, due to the specified gap between the drawing board 3 and the drawing table 1, the rotating mechanism can drive the drawing board 3 to move smoothly until a width greater than or equal to 1 is formed between the adjacent drawing boards 3. The specified interval of the rotating arc length ensures that there will be no collision when the drawing board 3 is rotated subsequently, or, when only one drawing board 3 needs to be moved, the corresponding rotating mechanism is slid in the opposite direction of the adjacent drawing board 3, and the formed interval must also be ensured to meet the requirements; after forming a suitable specified interval, if the inclination angle of the drawing board 3 is to be adjusted, the drawing board 3 is manually held and a torque is applied, and the drawing board 3 will rotate around the rotating shaft 20 according to the rotating connection between the rotating shaft 20 and the fixed plate 21 in the rotating mechanism. If the angle needs to be fine-tuned, the transmission shaft 22 can be rotated to drive the rotating shaft 20 to rotate by the meshing of the first rotating gear 23 and the second rotating gear 24, so as to achieve more precise angle adjustment until a suitable angle for drawing work is reached.

[0052] By setting the specified gap and the specified interval, the collision between adjacent drawing boards 3 when adjusting the tilt angle of the drawing board 3 or moving the drawing board 3 is effectively avoided, ensuring that the rotating mechanism can smoothly adjust the angle of the drawing board 3, making the tilt angle adjustment of the drawing board 3 more stable and reliable, improving the overall stability and durability of the device, and providing sufficient space for the movement and rotation of the drawing board 3, so that the draftsman can operate more smoothly without worrying about interference between components, and can focus more on drawing work, further improving the drawing experience and work efficiency.

[0053] Reference Figure 1-Figure 6 In one embodiment, the rotating mechanism includes a rotating shaft 20 and a plurality of fixed plates 21, the fixed plates 21 are slidably connected in the slide groove 6, the drawing board 3 is located between the opposite fixed plates 21, the rotating shaft 20 is rotatably connected to the fixed plates 21, and the rotating shaft 20 passes through the fixed plates 21 and is connected to the drawing board 3.

[0054] In the above embodiment, the rotating mechanism includes a rotating shaft 20 and a plurality of fixed plates 21. The rotating shaft 20 is a key component for realizing the rotation of the drawing board 3. It passes through the fixed plate 21 and is connected to the drawing board 3, so that the drawing board 3 can rotate around it. A rotatable connection method is adopted between the rotating shaft 20 and the fixed plate 21. A common connection method is connected through a bearing. This connection method can not only ensure that the rotating shaft 20 is stably fixed on the fixed plate 21, but also enable it to rotate smoothly, thereby driving the drawing board 3 to change its angle; the function of the plurality of fixed plates 21 is to provide stable support for the rotating shaft 20 and fix the drawing board 3 in a suitable position. The fixed plate 21 is slidably connected in the slide groove 6 of the drawing table 1, and its shape and size match the slide groove 6. The drawing board 3 is arranged between the relative fixed plates 21, and the connection between the rotating shaft 20 and the fixed plate 21 enables the drawing board 3 to rotate around the rotating shaft 20 within the limited range of the fixed plate 21. At the same time, the sliding of the fixed plate 21 in the sliding groove 6 also drives the drawing board 3 to adjust its position on the drawing table 1. The drawing table 1 serves as a basic platform and provides an installation basis for the rotating mechanism. The fixed plate 21 in the rotating mechanism realizes the position change on the drawing table 1 through the sliding connection with the sliding groove 6, and the rotating shaft 20 realizes the rotation function on the fixed plate 21, which finally drives the drawing board 3 to realize the position adjustment and angle change. The three cooperate with each other to form a system that can flexibly adjust the state of the drawing board 3.

[0055] When the position of the drawing board 3 needs to be adjusted, the drawing board 3 is pushed manually. Since the fixed plate 21 is connected to the drawing board 3 and is slidably connected in the slide groove 6, the drawing board 3 will drive the fixed plate 21 to slide in the slide groove 6, thereby realizing the translation of the drawing board 3 on the drawing table 1 until it reaches the desired position; if the inclination angle of the drawing board 3 is to be changed, the drawing board 3 is manually held and a torque is applied. At this time, the rotating shaft 20 rotates on the fixed plate 21, driving the drawing board 3 to rotate around the rotating shaft 20, and adjusting to a suitable angle according to the drawing requirements. For example, when drawing a stereogram, the drawing board 3 can be adjusted to a certain inclination angle to better express the three-dimensional sense of the object. Therefore, by sliding the fixed plate 21 in the slide groove 6, the position of the drawing board 3 on the drawing table 1 can be easily changed to adapt to different drawing requirements. The rotatable connection between the rotating shaft 20 and the fixed plate 21 allows the inclination angle of the drawing board 3 to be accurately adjusted. Whether it is a small angle inclination required when drawing a sketch or a larger angle adjustment when drawing a stereogram, it can be easily achieved, thereby improving the accuracy and quality of the drawing.

[0056] Reference Figure 1-Figure 6In one embodiment, the rotating mechanism further includes a transmission shaft 22, a first rotating gear 23 and a second rotating gear 24. The transmission shaft 22 is rotatably connected to a side of the fixed plate 21 away from the drawing board 3. The first rotating gear 23 is arranged on the transmission shaft 22, and the second rotating gear 24 is arranged on the rotating shaft 20, and the first rotating gear 23 and the second rotating gear 24 are meshed with each other.

[0057] In the above embodiment, the rotating mechanism also includes a transmission shaft 22, a first rotating gear 23 and a second rotating gear 24. The transmission shaft 22 is a component for transmitting torque and is rotatably connected to the side of the fixed plate 21 away from the drawing board 3. Its main function is to receive external rotational force and transmit it to the first rotating gear 23, thereby driving the second rotating gear 24 meshing therewith to rotate. The material of the transmission shaft 22 usually has a certain strength and toughness to ensure that it will not be deformed or damaged during the torque transmission process; the first rotating gear 23 is installed on the transmission shaft 22 and rotates with the transmission shaft 22. Its gear teeth are meshed with the gear teeth of the second rotating gear 24. Through the bite action between the teeth, the rotational motion of the transmission shaft 22 is transmitted to the second rotating gear 24, thereby realizing the transmission of force and motion. The size, module and other parameters of the first rotating gear 23 are matched with the second rotating gear 24 to ensure the accuracy and effectiveness of the meshing; the second rotating gear 24 is set on the rotating shaft 20 and meshes with the first rotating gear 23. When the first rotating gear 23 rotates, the second rotating gear 24 The moving gear 24 will rotate accordingly, thereby driving the rotating shaft 20 to rotate. The rotating shaft 20 is connected to the drawing board 3, so the rotation of the second rotating gear 24 finally realizes the fine adjustment of the inclination angle of the drawing board 3. The fixed plate 21 provides a stable support and installation position for the transmission shaft 22 and the rotating shaft 20. The transmission shaft 22 is located on the side of the fixed plate 21 away from the drawing board 3, and is meshed with the second rotating gear 24 located on the rotating shaft 20 through the first rotating gear 23 to form a transmission system. The drawing board 3 is connected to the entire transmission system through the rotating shaft 20. When an external force is applied to the transmission shaft 22 to rotate it, the power is transmitted to the rotating shaft 20 through the first rotating gear 23 and the second rotating gear 24 in turn, thereby realizing the fine adjustment of the inclination angle of the drawing board 3, so that the various components work together to accurately control the angle of the drawing board 3, and the friction between the rotating shaft 20 and the transmission shaft 22 and the fixed plate 21 respectively can resist the influence of the gravity of the drawing board 3 to a certain extent, so that the drawing board 3 is maintained at the set inclined position when it is not disturbed by a large external force.

[0058] When the angle of the drawing board 3 needs to be fine-tuned, the draftsman uses a suitable tool (such as a handle, etc.) to apply a rotational force to the transmission shaft 22 on the side of the fixed plate 21 away from the drawing board 3, and the transmission shaft 22 starts to rotate, driving the first rotating gear 23 installed thereon to rotate synchronously. Since the first rotating gear 23 and the second rotating gear 24 are meshed with each other, the rotation of the first rotating gear 23 drives the second rotating gear 24 to rotate, and then drives the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 enables the drawing board 3 connected thereto to achieve fine-tuning of the tilt angle. The draftsman can continue to apply rotational force according to actual needs until the drawing board 3 is tilted. 3 can achieve an ideal tilt angle. Through the transmission combination of the transmission shaft 22, the first rotating gear 23 and the second rotating gear 24, the accurate fine adjustment of the tilt angle of the drawing board 3 can be achieved. In architectural design drawing, for some details or drawing tasks that require precise angles, this fine adjustment function can help the draftsman to better present the design intention and improve the accuracy and quality of the drawing. Compared with directly manually adjusting the angle of the drawing board 3, using the transmission method of the transmission shaft 22 and the gear, the draftsman only needs to apply a small rotational force to the transmission shaft 22 at a suitable position to adjust the angle of the drawing board 3.

[0059] Reference Figure 1-Figure 4 In one embodiment, the sliding assembly 41 includes a fixed vertical rod 410, a sliding block 411 and a connecting plate 412. A receiving groove 413 is provided on the installation frame 40. The fixed vertical rod 410 and the sliding block 411 are respectively arranged in the receiving groove 413. The sliding block 411 is slidably connected to the fixed vertical rod 410, and the sliding block 411 passes through the installation frame 40. A connecting rod 414 is provided on the sliding block 411, and the connecting plate 412 is arranged at one end of the sliding block 411 away from the connecting rod 414.

[0060] In the above embodiment, the sliding assembly 41 includes a fixed vertical rod 410, a sliding block 411 and a connecting plate 412. The fixed vertical rod 410 is an important supporting component in the sliding assembly 41. It is vertically installed in the receiving groove 413 of the mounting frame 40 to provide guidance and stable support for the up and down sliding of the sliding block 411. The fixed vertical rod 410 usually has a certain length and strength to ensure that the sliding block 411 will not be bent or deformed during the repeated sliding of the sliding block 411. Its surface may be specially treated to reduce the friction between it and the sliding block 411 to make the sliding smoother. The sliding block 411 is located in the receiving groove 413 and is slidably connected to the fixed vertical rod 410. It can automatically move along the length direction of the fixed vertical rod 410. By moving up and down, the sliding block 411 passes through the mounting frame 40, which enables it to not only slide in the accommodating groove 413 inside the mounting frame 40, but also connect and transmit with other components (such as the cleaning component 42) on the other side of the mounting frame 40. The connecting rod 414 provided on the sliding block 411 is used to receive external operating force, thereby driving the entire sliding block 411 to slide on the fixed vertical rod 410; one end of the connecting plate 412 is connected to the side of the sliding block 411 away from the connecting rod 414, and it serves to connect the sliding block 411 and the cleaning component 42, and transmits the up and down movement of the sliding block 411 to the cleaning component 42, so that the cleaning component 42 can move accordingly, thereby realizing the cleaning operation of the drawing board 3. The mounting frame 40 serves as a basic component and provides an installation position for the fixed vertical rod 410, the sliding block 411, etc. The fixed vertical rod 410 is fixed in the receiving groove 413 of the mounting frame 40, and the sliding block 411 is sleeved on the fixed vertical rod 410 and can slide on its surface, receiving external operating force through the connecting rod 414, and the connecting plate 412 transmits the movement of the sliding block 411 to the cleaning component 42. The various components are closely matched to form a sliding system that can realize the up and down movement of the cleaning component 42, so as to effectively clean the drawing board 3.

[0061] When it is necessary to clean the drawing board 3, the operator manually holds the connecting rod 414 and applies an upward or downward force. Since the sliding block 411 is connected to the connecting rod 414, under the action of the force, the sliding block 411 begins to slide on the fixed vertical rod 410 along the direction of the accommodating groove 413. The sliding of the sliding block 411 is transmitted to the cleaning component 42 through the connecting plate 412, so that the cleaning component 42 moves up and down synchronously with the sliding block 411. The cleaning component 42 contacts the surface of the drawing board 3 during the movement, thereby cleaning the drawing board 3 to remove dust, debris and other debris on the drawing board 3. During the operation, the operator can repeat the operation multiple times according to the degree of dirtiness of the drawing board 3 and the cleaning needs. The cleaning component 42 is forced to move repeatedly on the drawing board 3 to ensure the cleaning effect. The cooperation between the fixed vertical rod 410 and the sliding block 411 provides a stable sliding guide to ensure that the cleaning component 42 always maintains a linear motion during the up and down movement without deviation or shaking, thereby ensuring the accuracy and stability of the cleaning operation and being able to evenly clean various parts of the drawing board 3. The sliding block 411 is connected to the cleaning component 42 through the connecting plate 412, and can effectively transmit the operating force applied to the connecting rod 414 from the outside to the cleaning component 42, so that the cleaning component 42 can respond to the movement of the sliding block 411 in a timely and accurate manner, thereby achieving efficient cleaning of the drawing board 3 and saving cleaning time and manpower.

[0062] Reference Figure 1-Figure 4 In one embodiment, the cleaning assembly 42 includes a rotating rod 420, a cleaning roller 421 and a plurality of first cleaning brushes 422, the rotating rod 420 is rotatably connected to the connecting plate 412, the cleaning roller 421 is fixedly connected to one end of the rotating rod 420 away from the connecting plate 412, a plurality of first cleaning brushes 422 are arranged in an array on the cleaning roller 421, and the first cleaning brushes 422 are in contact with the drawing board 3.

[0063] In the above embodiment, the cleaning component 42 includes a rotating rod 420, a cleaning roller 421 and a plurality of first cleaning brushes 422. The rotating rod 420 is a key connecting component in the cleaning component 42, and one end of the rotating rod 420 is rotatably connected to the connecting plate 412, so that the cleaning roller 421 can rotate around the rotating rod 420 as the axis. The material of the rotating rod 420 has a certain strength and wear resistance to ensure that it will not be easily damaged during frequent use. At the same time, its rotating connection method can flexibly adapt to various movement requirements of the cleaning roller 421 during the cleaning process; the cleaning roller 421, as the main executive component for cleaning the drawing board 3, is fixedly connected to the end of the rotating rod 420 away from the connecting plate 412, and moves with the rotation of the rotating rod 420. The surface of the cleaning roller 421 is a plurality of The first cleaning brush 422 provides an attachment base, and its shape and size are reasonably designed, which can effectively cover a certain cleaning range on the surface of the drawing board 3 to ensure comprehensive cleaning; the first cleaning brush 422 is made of a flexible material, such as soft nylon thread, etc. This flexible material can not only ensure that the surface of the drawing board 3 will not be scratched during the cleaning process, but also effectively absorb and remove dust, debris and other debris on the drawing board 3. Multiple first cleaning brushes 422 are arranged in an array on the cleaning roller 421, and are arranged closely, so that the cleaning roller 421 can form a continuous cleaning surface when it contacts the drawing board 3, and its length is greater than or equal to the distance between the cleaning roller 421 and the drawing board 3, ensuring that each brush can fully contact the drawing board 3 during the cleaning process, leaving no cleaning dead corners;

[0064] When it is necessary to clean the drawing board 3, the operator drives the connecting plate 412 to move up and down through the sliding component 41 (such as pushing the connecting rod 414). The movement of the connecting plate 412 drives the rotating rod 420 and the cleaning roller 421 to move up and down synchronously. At this time, the first cleaning brush 422 slides on the surface of the drawing board 3. Due to the effect of friction, the cleaning roller 421 begins to rotate around the rotating rod 420. As the sliding component 41 continues to drive the cleaning component 42 to move up and down, the first cleaning brush 422 continuously rolls and slides on the drawing board 3 to comprehensively clean the drawing board 3. During the cleaning process, the flexible first cleaning brush 422 can penetrate into the fine texture on the surface of the drawing board 3 to absorb and Sweep away dust, debris and other sundries, and clean them off the drawing board 3 to ensure that the drawing board 3 is clean. The operator can move the cleaning component 42 back and forth multiple times according to the degree of dirtiness of the drawing board 3 to achieve the best cleaning effect, effectively protect the integrity of the drawing board 3, extend the service life of the drawing board 3, and ensure the normal progress of the drawing work. In addition, multiple first cleaning brushes 422 that are densely arranged and of sufficient length can completely cover the surface of the drawing board 3. Under the dual effects of rotation and sliding, both dust and tiny debris can be effectively cleaned, ensuring the cleanliness of the drawing board 3, providing the draftsman with a clean and tidy drawing surface, which is conducive to improving the drawing quality.

[0065] Reference Figure 1-Figure 8 In one embodiment, the multifunctional drawing device for architectural design students further includes a dispensing mechanism 5, which includes a reagent box 50, a telescopic component 51 and a wetting component 52. The reagent box 50 is fixedly connected to the sliding block 411, and the reagent box 50 and the cleaning component 42 are located on the same side. The telescopic component 51 is arranged on a side of the reagent box 50 close to the cleaning component 42. The wetting component 52 is arranged on the telescopic component 51 and contacts the cleaning component 42, and the wetting component 52 is slidably connected to the reagent box 50. When the cleaning component 42 rotates, the force of the cleaning component 42 is transmitted to the telescopic component 51 through the wetting component 52, so that the telescopic change of the telescopic component 51 drives the up and down movement of the wetting component 52, and the alcohol in the reagent box 50 is transported to the wetting component 52 for soaking the cleaning component 42.

[0066] In the above embodiment, the multifunctional drawing device for architectural design students also includes a dispensing mechanism 5, which includes a storage box 50, a telescopic component 51 and a wetting component 52. The storage box 50 is mainly used to store liquid reagents such as alcohol required for cleaning the drawing board 3. Its material usually has good sealing properties to prevent alcohol from volatilizing and leaking. Common materials include plastic or metal, etc. It is firmly fixedly connected to the sliding block 411, such as welding, screwing or clamping, to ensure that during the movement of the sliding block 411, the storage box 50 can stably move with it, always remain on the same side as the cleaning component 42, and the relative position is fixed. It ensures that during the entire cleaning process, the agent tank 50 can continuously provide alcohol to the cleaning component 42 to achieve the continuity of the cleaning function; the telescopic component 51 is installed on the side of the agent tank 50 close to the cleaning component 42, and there is a fixed connection structure between the agent tank 50 to ensure the stability of its position. At the same time, the telescopic component 51 is in direct contact and connection with the wetting component 52, and can transmit its own telescopic movement to the wetting component 52, driving the wetting component 52 to slide up and down on the surface of the agent tank 50, thereby controlling the outflow and stop of alcohol.

[0067] The main function of the wetting component 52 is to realize the wetting operation of the cleaning component 42 under the drive of the telescopic component 51, so as to ensure that the cleaning component 42 can better remove stains when cleaning the drawing board 3. The wetting component 52 is arranged on the telescopic component 51 and forms a linkage relationship with the telescopic component 51. When the telescopic component 51 is telescopically changed, the wetting component 52 will move up and down accordingly. At the same time, the wetting component 52 is in close contact with the cleaning component 42. When alcohol is transported from the storage tank 50 to the wetting component 52, the alcohol can be quickly and effectively transferred to the cleaning component 42, so that the bristles of the cleaning component 42 are moistened, thereby improving the cleaning effect. In addition, the wetting component 52 is slidably connected to the storage tank 50. Its movement trajectory is limited by the surface structure of the agent storage box 50, which ensures stability and accuracy during the movement. The agent storage box 50 provides storage space for alcohol and is the material basis of the entire cleaning process. The telescopic component 51, as an intermediate link in power transmission and control, converts the rotational force of the cleaning component 42 into the up and down movement of the wetting component 52. The wetting component 52, driven by the telescopic component 51, realizes the controllable delivery of alcohol and the wetting of the cleaning component 42. The three cooperate with each other to form an organic whole, which together completes the function of automatically providing detergent during the cleaning process of the drawing board 3, thereby improving the degree of automation and cleaning efficiency of the cleaning function of the drawing device.

[0068] Alcohol is delivered to the cleaning component 42 through the dispensing mechanism 5, so that the bristles of the cleaning component 42 remain moist. When cleaning the drawing board 3, the moist bristles combined with the dissolving effect of alcohol can more thoroughly remove stains, significantly improve the cleaning effect, and restore the drawing board 3 to a clean and tidy state, providing good surface conditions for drawing work. The entire dispensing process is automatically triggered by the rotation of the cleaning component 42, and there is no need for the draftsman to manually add detergent. This automated design greatly simplifies the cleaning operation process. The draftsman only needs to focus on cleaning the drawing board 3 itself, reducing additional operating steps and time costs. At the same time, the automated dispensing can ensure the timely supply of alcohol during the cleaning process, so that the cleaning component 42 is always in the best cleaning state, further improving the cleaning efficiency and quality.

[0069] Reference Figure 1-Figure 8 In one embodiment, the telescopic assembly 51 includes a limiting vertical rod 510, a limiting slider 511 and a telescopic spring 512. A limiting groove 513 is provided on the side of the agent storage box 50 close to the cleaning assembly 42. The limiting vertical rod 510 is fixedly connected in the limiting groove 513. The telescopic spring 512 is sleeved on the limiting vertical rod 510. The limiting slider 511 is slidably connected to the limiting vertical rod 510, and the limiting slider 511 is connected to the telescopic spring 512.

[0070] In the above embodiment, the telescopic assembly 51 includes a limiting vertical rod 510, a limiting slider 511 and a telescopic spring 512. The limiting vertical rod 510 is a slender rod-shaped structure with a certain strength, usually made of metal material (such as stainless steel). It is vertically fixedly connected to the limiting groove 513 on the side of the storage box 50 close to the cleaning assembly 42, providing a precise sliding track for the limiting slider 511, ensuring that the limiting slider 511 can only move up and down in a straight line along the direction of the vertical rod, thereby limiting the movement direction of the entire telescopic assembly 51 and the wetting assembly 52 connected thereto, ensuring the accuracy and stability of the movement; The slider 511 is block-shaped, and a through hole compatible with the limit vertical rod 510 is provided at the center thereof. The slider 511 is sleeved on the limit vertical rod 510 through the through hole to achieve a sliding connection with the limit vertical rod 510. One side of the limit slider 511 is connected to the telescopic spring 512, and the other side is fixedly connected to the relevant parts of the wetting component 52 (such as the limit baffle 520). During operation, the limit slider 511 can slide up and down smoothly on the limit vertical rod 510, transmit the force from the cleaning component 42 to the telescopic spring 512, and adjust the position under the action of the spring elastic force, thereby driving the wetting component 52 to move accordingly.

[0071] The telescopic spring 512 is made of spring steel with good elasticity, is sleeved on the limiting vertical rod 510, and is located between the storage box 50 and the limiting slider 511. One end of the telescopic spring 512 is fixedly connected to the inner wall of the storage box 50 or a specific position at the bottom of the limiting groove 513, and the other end is connected to the limiting slider 511. When the cleaning component 42 rotates to generate a force and transmits it to the limiting slider 511, the limiting slider 511 will squeeze or stretch the telescopic spring 512, causing the spring to undergo elastic deformation, store or release elastic potential energy, and through the expansion and contraction changes of the spring, the position of the limiting slider 511 is accurately controlled, thereby controlling the up and down movement of the wetting component 52, and realizing the opening and closing control of the alcohol outlet hole 523; the limiting groove 513 is arranged on the side of the storage box 50 close to the cleaning component 42, and its shape matches the limiting vertical rod 510, and is usually The long groove structure has a certain depth. The limit groove 513 provides an installation position for the limit vertical rod 510, so that the limit vertical rod 510 can be firmly fixed on the storage box 50. At the same time, it also plays a certain protection and positioning role for the limit vertical rod 510, ensuring that the limit vertical rod 510 will not deviate or shake during the entire working process, thereby ensuring the normal operation of the telescopic component 51. Through the precise sliding of the limit slider 511 on the limit vertical rod 510 and the elastic deformation of the telescopic spring 512, the relative position of the limit baffle 520 in the wetting component 52 and the agent outlet hole 523 of the storage box 50 can be accurately controlled, thereby achieving precise control of the alcohol outflow amount. When cleaning the drawing board 3, alcohol can be supplied in an appropriate amount according to actual needs, which not only ensures a good cleaning effect but also avoids alcohol waste.

[0072] Reference Figure 1-Figure 8 In one embodiment, the wetting component 52 includes a limiting baffle 520 and a plurality of second cleaning brushes 521, a storage chamber 522 with an inclined bottom is provided in the storage box 50, a discharge hole 523 is provided at the bottom of the storage chamber 522, and the discharge hole 523 is located at the top of the limiting groove 513, the limiting baffle 520 is connected to the limiting slider 511, and the limiting baffle 520 corresponds to the discharge hole 523, a plurality of second cleaning brushes 521 are arranged in an array on a side of the limiting baffle 520 away from the storage chamber 522, and the second cleaning brush 521 is in contact with the first cleaning brush 422.

[0073] In the above embodiment, the wetting component 52 includes a limiting baffle 520 and a plurality of second cleaning brushes 521. The storage cavity 522 is located inside the storage box 50 and is a space for storing alcohol. The bottom thereof is designed to be inclined downward from the side away from the drawing board 3 to the side close to the drawing board 3. This design is conducive to the alcohol flowing toward the outlet hole 523 under the action of gravity; the outlet hole 523 is arranged at the bottom of the storage cavity 522 near the top of the limiting groove 513, and is the channel for the alcohol to flow out of the storage box 50; the limiting baffle 520 is a flat plate-shaped component, and its material is usually plastic or metal sheet, and has a certain strength and flexibility. It is tightly connected to the limiting slider 511 and can slide up and down on the surface of the storage box 50 with the limiting slider 511. Its main function is to The opening and closing of the agent outlet hole 523 of the agent storage box 50 is controlled, and the outflow or stop of alcohol is achieved by changing the relative position with the agent outlet hole 523. When the limit baffle 520 slides downward, the agent outlet hole 523 can be gradually exposed to allow the alcohol to flow out. When sliding upward, the agent outlet hole 523 can be completely covered to prevent alcohol leakage. The second cleaning brush 521 is made of a soft and absorbent material, such as fiber bristles or sponge strips. Multiple second cleaning brushes 521 are arranged in an array on the side of the limit baffle 520 away from the agent storage chamber 522. The length design allows them to fully transfer alcohol and friction when in contact with the first cleaning brush 422. They not only act as a bridge in the alcohol transfer process, but also assist in cleaning the drawing board 3 to a certain extent, thereby improving the cleaning effect. The limiting baffle 520 is connected to the limiting slider 511, and slides on the surface of the agent storage box 50 driven by the telescopic component 51, so as to control the opening and closing of the agent outlet hole 523. The second cleaning brush 521 is fixed on the limiting baffle 520, and contacts with the first cleaning brush 422 of the cleaning component 42, so as to realize alcohol transfer and friction force transfer. The agent storage cavity 522 provides storage space for alcohol. Its inclined design and the position of the agent outlet hole 523 work together to ensure that the alcohol can accurately flow out to the second cleaning brush 521 at the right time, and then be transferred to the first cleaning brush 422, so as to realize effective cleaning of the drawing board 3.

[0074] When the drawing device does not start the cleaning function, the limit slider 511 is in the initial position under the action of the telescopic spring 512. At this time, the limit baffle 520 completely blocks the discharge hole 523, and the alcohol cannot flow out. The storage chamber 522 is filled with alcohol, and the second cleaning brush 521 is stationary and slightly in contact with the first cleaning brush 422. When the cleaning component 42 starts to rotate to clean the drawing board 3, the first cleaning brush 422 rotates and generates friction with the second cleaning brush 521, pushing the second cleaning brush 521 to move, thereby driving the limit slider 511 to slide upward. As the limit slider 511 descends, the limit baffle 520 gradually opens the discharge hole 523. 23. The alcohol in the storage chamber 522 flows to the second cleaning brush 521 under the action of gravity. After the alcohol soaks the second cleaning brush 521, it is transferred to the first cleaning brush 422 to moisten it and enhance the cleaning effect. During the cleaning process, as long as the cleaning component 42 keeps rotating, the friction between the first cleaning brush 422 and the second cleaning brush 521 will continue to act, so that the limiting slider 511 is kept in a suitable position, ensuring that the dispensing hole 523 continues to discharge alcohol. After the cleaning is completed, the cleaning component 42 stops rotating, the friction disappears, and the telescopic spring 512 returns the limiting slider 511 to the initial position, closing the dispensing hole 523 and stopping the alcohol supply.

[0075] Through the ingenious cooperation between the limiting baffle 520 and the agent outlet 523, and the position change of the limiting slider 511 in the limiting groove 513, the outflow of alcohol can be accurately controlled. Under different cleaning requirements, the appropriate amount of alcohol can be supplied, which not only ensures the cleaning effect, but also avoids the waste of alcohol, and reduces the adverse effects of excessive alcohol on the drawing board 3. In the process of contact with the first cleaning brush 422, the second cleaning brush 521 can not only effectively transfer alcohol from the agent storage box 50 to the cleaning component 42, but also use its own soft material and array arrangement to further wipe and absorb stains when cleaning the drawing board 3, thereby improving the cleaning efficiency. At the same time, the friction force transmission between the first cleaning brush 422 and the second cleaning brush 521 realizes mechanical linkage, making the entire cleaning process more automated and efficient.

[0076] Reference Figure 1-Figure 9 In one embodiment, the multifunctional drawing device for architectural design students further comprises a plurality of magnetic plates 7, wherein the magnetic plates 7 are fixedly connected to a side of the storage box 50 away from the drawing board 3, and the magnetic plates 7 extend along the entire length direction of the storage box 50, and when the plurality of magnetic plates 7 are arranged relative to each other, the plurality of magnetic plates 7 are arranged to attract each other with corresponding opposite poles.

[0077] In the above embodiment, the multifunctional drawing device for architectural design students also includes a plurality of magnetic plates 7, which are made of magnetic materials, such as permanent magnets or electromagnets, and are usually in the shape of long strips to meet the installation requirements along the entire length of the storage box 50. The magnetic plates 7 are fixedly connected to the side of the storage box 50 away from the drawing board 3. The fixed connection method can be glue bonding, screw fixing or slot clamping, etc., to ensure that the magnetic plates 7 will not fall off or shift easily during use. The main function of the magnetic plates 7 is to utilize its magnetism to interact with other magnetic plates 7 under specific conditions to achieve the internal and external adjustment of the drawing board 3. The internal space is closed or opened. When the drawing board 3 is in a vertical state, multiple magnetic plates 7 are arranged relatively to each other. Due to the principle of attraction between opposite poles, they will attract each other and fit tightly. At the same time, when the two mounting frames 40 are vertically fitted together, a sealing ring is arranged on the mounting frame 40, so that a closed barrier is formed on one side of the drawing board 3 through the mounting frame 40 and the magnetic plate 7, which effectively blocks external dust and other pollutants from entering the interior of the drawing board 3. The design of this connection and position relationship makes full use of the magnetic properties of the magnetic plate 7, provides additional protection for the drawing board 3, and improves the overall performance of the drawing device.

[0078] When the drawing device is not using the drawing board 3 for drawing or the drawing board 3 is in a non-vertical state, the magnetic plate 7 is in a natural state and does not affect other operations of the drawing device. When the drawing work is completed or the drawing board 3 needs to be stored, the drawing board 3 is rotated to a vertical state. When the drawing board 3 is completely rotated to the vertical state, since the magnetic plate 7 extends along the entire length of the storage box 50 and the opposite poles attract each other when they are relatively arranged, the magnetic plate 7 will automatically attract each other and fit tightly under the action of magnetic force, forming a closure for the inside of the drawing board 3, which can significantly reduce the chance of external dust, impurities and other pollutants entering the interior of the drawing board 3, help to keep the inner wall of the drawing board 3 clean, and avoid long-term accumulation of dust to damage the surface quality of the drawing board 3, such as scratching the surface of the drawing board 3 and affecting the clarity of the drawing lines, thereby extending the service life of the drawing board 3 and ensuring that it can always provide a good drawing surface for drawing work.
