Description

Technical Field

[0001] The present invention relates to the technical field of multimedia live broadcast and recording, and more specifically, to a multimedia live broadcast and recording device for a smart classroom. Background Art

[0002] The smart classroom multimedia live broadcast and recording device is a modern educational tool designed to improve teaching efficiency and student learning experience. It combines audio and video technology, real-time interactive functions and online learning platforms, and can realize live teaching and course recording outside the classroom. Teachers can use this device to transmit course content to remote students in real time, breaking spatial limitations and providing flexible learning options. At the same time, the recording function allows students to review courses at any time, which is convenient for review and in-depth understanding. In addition, this device also supports a variety of interactive forms. Students can ask questions and participate in voting through the online platform, thereby enhancing classroom participation and enthusiasm.

[0003] However, in actual use, these devices face challenges unique to the classroom environment, especially when students frequently enter and exit the classroom, and when teachers use traditional chalk to write on the blackboard, a large amount of fine dust will inevitably be raised. These dust particles are light and have a certain amount of static electricity, which can easily float in the air and eventually stick to the multimedia display screen.

[0004] As the core output interface of the live broadcast and recording device, the cleanliness and transparency of the screen are crucial to ensuring a high-quality visual experience. The adhesion of dust will not only reduce the brightness, contrast and color saturation of the screen, affecting students' viewing experience, but may also interfere with the sensitivity of the touch screen, resulting in poor operation or mis-touch.

[0005] In view of this, we propose a multimedia live broadcast and recording device for smart classrooms. Summary of the invention

[0009] Preferably, the shift plate is an inclined fan blade structure, the fixed rod is rotatably connected to the top inner wall of the connecting frame, the top inner wall of the connecting frame is rotatably connected to a turntable, the outer wall of the fixed rod is fixedly connected to a reverse disk, and the outer wall of the turntable respectively abuts against the inner wall of the cleaning roller and the outer wall of the reverse disk.

[0010] Preferably, the inner diameter of one end of the spring fixed to the cleaning brush gradually expands toward the other end, and the inner diameter of the spring gradually expands to form a conical structure.

[0011] Preferably, the receiving grooves located at the upper side of the cleaning roller are arranged obliquely toward the bottom thereof, and the cleaning brushes are located in the receiving grooves and arranged obliquely corresponding thereto.

[0012] Preferably, outer walls of the writing board are respectively fixedly connected with symmetrically arranged storage handles, and the storage handles cover one end of the twist plate located outside the frame.

[0014] Preferably, a filter bag is arranged inside the frame, and the filter bag covers the bottom opening of the impurity discharge trough.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention sets a frame, a writing board, a touch display screen, a camera, a microphone, a twist groove, a twist plate, a connecting frame, a cleaning roller, a cleaning brush, a transmission disk, and a friction rod, so that when the writing board moves, the cleaning roller will move synchronously, and the cleaning roller will drive the cleaning roller to move when moving, and the cleaning roller will drive the transmission disk to move together when moving, so that when the transmission disk moves, it starts to rotate due to the friction between the friction rod, so that the rotation of the transmission disk drives the cleaning roller to rotate, so that the rotation of the cleaning roller drives the cleaning brush to clean the surface of the touch display screen.

In this reciprocating manner, when the cleaning roller rotates, the cleaning brush will vibrate, thereby increasing the cleaning effect of the cleaning brush on the touch display screen, and during the vibration process, the cleaning brush will also shake off the dust stuck on its bristles, thereby preventing the cleaning effect from being affected after the dust sticks to the cleaning brush.

[0018] 3. In the present invention, the inner diameter of one end of the spring fixed with the cleaning brush gradually expands toward the other end to form a conical structure, which causes it to exhibit a nonlinear mechanical response when compressed or stretched, and can generate a greater elastic force than an ordinary spring, thereby making the vibration characteristics more flexible and increasing the effect of the cleaning brush vibrating to clean the touch display screen and shake off dust.

[0029] like Figures 1 to 6 As shown, a multimedia live broadcast and recording device for a smart classroom comprises a frame 1, the inner surface of the frame 1 is slidably connected with a plurality of symmetrically arranged writing boards 2 and a touch display screen 3, a camera 4 and a microphone 5 arranged inside the frame 1, the outer walls of the writing boards 2 are respectively provided with torsion grooves 6, the inside of the torsion grooves 6 is hinged with torsion plates 7 through torsion springs, the two ends of the torsion plates 7 respectively pass through the torsion grooves 6 to the inside and outside of the frame 1, one end of the torsion plate 7 located inside the frame 1 is fixedly connected with a connecting frame 8, the inner wall of the connecting frame 8 is rotatably connected with a cleaning roller 9, the outer wall of the cleaning roller 9 is provided with a plurality of groups of cleaning brushes 10, the lower side main shaft of the cleaning roller 9 passes through the connecting frame 8 to the bottom thereof and is fixedly connected with a transmission disk 11, and the bottom inner wall of the frame 1 is fixedly connected with a friction rod 12;

[0030] Specifically, the images and sounds are collected through the camera 4 and the microphone 5, and the images are displayed through the touch screen 3. When dust is adhered to the touch screen 3, the torsion plate 7 is pulled, and the torsion plate 7 is twisted by force and drives the writing board 2 to move, so that the movement of the writing board 2 drives the torsion plate 7 to move together, and the torsion of the torsion plate 7 will also drive the connecting frame 8 to twist together, and the torsion of the connecting frame 8 drives the cleaning roller 9 to twist, and the torsion of the cleaning roller 9 drives the transmission disk 11 to fit with the friction rod 12 during the torsion process. Similarly, in the process of movement of the writing board 2, the cleaning roller 9 will move synchronously, and the cleaning roller 9 will drive the cleaning roller 9 to move when it moves, and the cleaning roller 9 drives the transmission disk 11 to move together when it moves, so that the transmission disk 11 starts to rotate due to the friction between the friction rod 12 when it moves, so that the transmission disk 11 rotates and drives the cleaning roller 9 to rotate, so that the cleaning roller 9 rotates and drives the cleaning brush 10 to clean the surface of the touch screen 3;

[0031] It should be noted that, only when the touch screen 3 needs to be cleaned, the twist plate 7 is pulled so that the cleaning roller 9 drives the cleaning brush 10 to clean the touch screen 3. When the touch screen 3 does not need to be cleaned, the writing board 2 can be directly opened, so that the cleaning roller 9 will not rotate and approach the touch screen 3 to clean it, thereby preventing excessive cleaning of the touch screen 3 and causing scratches on its surface.

[0032] like Figures 4 to 8 As shown, further, the outer wall of the cleaning roller 9 is evenly provided with a plurality of receiving grooves 13, the interior of the cleaning roller 9 is hollow, and the receiving grooves 13 are communicated with the interior of the cleaning roller 9, the cleaning brushes 10 are respectively arranged in the receiving grooves 13, the inner wall of the receiving grooves 13 is fixedly connected with a spring 14, the other end of the spring 14 is fixedly connected with the cleaning brush 10, the end of the cleaning brush 10 away from the bristles thereof extends to the interior of the cleaning roller 9, the top inner wall of the connecting frame 8 is provided with a fixing rod 15 extending to the interior of the cleaning roller 9, and the outer wall of the fixing rod 15 is evenly fixedly connected with a plurality of paddles 16;

[0033] Specifically, the cleaning brush 10 is arranged in the storage groove 13 and is connected to the inner wall of the storage groove 13 by a spring 14. Because the spring 14 is tough, when the cleaning roller 9 rotates to drive the cleaning brush 10 to rotate together, the end of the cleaning brush 10 away from its bristles will cyclically contact with the paddle 16 on the fixed rod 15 and be pushed by the paddle 16, and then reset under the elastic force of the spring 14. In this reciprocating manner, when the cleaning roller 9 rotates, the cleaning brush 10 will vibrate, thereby increasing the cleaning effect of the cleaning brush 10 on the touch display screen 3, and the cleaning brush 10 will also shake off the dust stuck on its bristles during the vibration process, thereby preventing the cleaning effect of the cleaning brush 10 from being affected after the dust sticks to the cleaning brush 10.

[0034] like Figures 4 to 8 As shown, further, the dial plate 16 is an inclined fan blade structure, the fixed rod 15 is rotatably connected to the top inner wall of the connecting frame 8, the top inner wall of the connecting frame 8 is rotatably connected to the middle turntable 17, the outer wall of the fixed rod 15 is fixedly connected to the reverse disk 18, and the outer wall of the middle turntable 17 is respectively in contact with the inner wall of the cleaning roller 9 and the outer wall of the reverse disk 18;

[0035] Specifically, when the cleaning roller 9 rotates, its inner wall will drive the middle rotating disk 17 to rotate due to the friction between the middle rotating disk 17 and the middle rotating disk 17 will drive the reverse disk 18 to rotate due to the friction between the middle rotating disk 17 and the reverse disk 18, so that the reverse disk 18 drives the fixed rod 15 to rotate when rotating, and the rotation of the fixed rod 15 drives the paddle 16 to rotate. It should be noted that since the cleaning roller 9 drives the reverse disk 18 to rotate via the middle rotating disk 17, the rotation direction of the reverse disk 18 is opposite to that of the cleaning roller 9, so that the paddle 16 autonomously pokes the cleaning brush 10. To further increase the vibration effect of the cleaning brush 10, the paddle 16 is an inclined fan blade structure. When the paddle 16 rotates, it will also disturb the gas in the cleaning roller 9, so that the external gas enters the interior of the cleaning roller 9 from the storage groove 13, so that the external gas enters the interior of the cleaning roller 9 from the storage groove 13 together with the dust cleaned from the touch display screen 3, thereby preventing the dust from escaping in the air after being cleaned from the touch display screen 3, and then re-adhering to the touch display screen 3, thereby affecting the cleaning effect of the touch display screen 3.

[0036] like Figure 5 As shown, further, the inner diameter of one end of the spring 14 fixed to the cleaning brush 10 gradually expands toward the other end, and the inner diameter of the spring 14 gradually expands to form a tapered structure;

[0037] Specifically, the inner diameter of one end of the spring 14 fixed to the cleaning brush 10 gradually expands toward the other end to form a conical structure, which causes it to exhibit a nonlinear mechanical response when compressed or stretched, and can generate a greater elastic force than the ordinary spring 14, thereby making the vibration characteristics more flexible and increasing the effect of the cleaning brush 10 vibrating to clean the touch display screen 3 and shake off dust.

[0038] like Figure 7 As shown, further, the storage grooves 13 located at the upper side of the cleaning roller 9 are arranged in an inclined manner toward the bottom thereof, and the cleaning brush 10 is located in the storage grooves 13 and arranged in an inclined manner corresponding thereto;

[0039] Specifically, the storage grooves 13 located on the upper side of the cleaning roller 9 are arranged obliquely toward the bottom thereof, and the cleaning brushes 10 are located inside thereof and form a corresponding oblique arrangement therewith, so that when cleaning the touch display screen 3, the cleaning brush 10 on the upper side will clean the touch display screen 3 first, and then clean the touch display screen 3 from top to bottom in sequence, so that the dust cleaned off the touch display screen 3 is guided by the cleaning brush 10 and cleaned downward in sequence, thereby preventing the dust on the upper side of the dust touch display screen 3 from sticking to the surface of the touch display screen 3 again, thereby affecting the cleaning effect of the touch display screen 3.

[0040] like Figure 1 to Figure 2As shown, further, the outer walls of the writing board 2 are respectively fixedly connected with symmetrically arranged storage handles 19, and the storage handles 19 cover one end of the twisting plate 7 located outside the frame 1;

[0041] Specifically, by providing a storage wrench, it is convenient to pull the writing board 2 to move and open without pulling the twist plate 7, and the storage handle 19 can also support the twist plate 7 when the twist plate 7 is pulled, thereby preventing the twist plate 7 from being over-twisted and affecting the cleaning effect of the touch display screen 3.

[0042] like Figures 2 to 3 As shown, further, the bottom inner wall of the frame 1 is provided with a drainage groove 20 communicating with the outside, and the interior of the cleaning roller 9 is communicated with the interior of the drainage groove 20;

[0043] Specifically, after the paddle plate 16 guides the air and dust into the interior of the cleaning roller 9, in order to prevent the dust from accumulating inside the cleaning roller 9, as the paddle plate 16 rotates, the paddle plate 16 will guide the air and dust entering the interior of the cleaning roller 9 into the impurity removal groove 20, and then the air and dust will be discharged from the interior of the frame 1 through the impurity removal groove 20.

[0044] like Figure 1 to Figure 2 As shown, further, a filter bag 21 is arranged inside the frame 1, and the filter bag 21 covers the bottom opening of the impurity discharge trough 20;

[0045] Specifically, the dust is collected by the filter bag 21, thereby preventing the dust from escaping in the classroom and affecting the learning and teaching environment of students and teachers.

[0046] Working principle: This embodiment provides a multimedia live broadcast and recording device for a smart classroom, which collects images and sounds through a camera 4 and a microphone 5, and displays the images through a touch screen 3. When dust adheres to the touch screen 3, the twisting plate 7 is pulled, and the twisting plate 7 is twisted by force and drives the writing board 2 to move, so that the movement of the writing board 2 drives the twisting plate 7 to move together, and the twisting of the twisting plate 7 will also drive the connecting frame 8 to twist together, and the twisting of the connecting frame 8 drives the cleaning roller 9 to twist, and the twisting process of the cleaning roller 9 drives the transmission disk 11 to fit with the friction rod 12. Similarly, in the process of moving the writing board 2, the cleaning roller 9 will move synchronously, and the cleaning roller 9 will drive the cleaning roller 9 to move when it moves, and the cleaning roller 9 will drive the transmission disk 11 to move together when it moves, so that the transmission disk 11 starts to rotate due to the friction between the friction rod 12 when it moves, so that the transmission disk 11 rotates and drives the cleaning roller 9 to rotate, so that the cleaning roller 9 rotates and drives the cleaning brush 10 to clean the surface of the touch screen 3;

[0047] It should be noted that, only when the touch screen 3 needs to be cleaned, the twist plate 7 is pulled so that the cleaning roller 9 drives the cleaning brush 10 to clean the touch screen 3. When the touch screen 3 does not need to be cleaned, the writing board 2 can be directly opened, so that the cleaning roller 9 will not rotate and approach the touch screen 3 to clean it, thereby preventing excessive cleaning of the touch screen 3 and causing scratches on its surface.

[0048] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
