Technical Field

[0001] The invention relates to the technical field of teaching equipment, in particular to an English follow-up reading device for English teaching. Background Art

[0002] English teaching refers to the process of teaching English to people whose first language is English or not. English teaching involves a variety of professional theoretical knowledge, including linguistics, second language acquisition, lexicology, syntax, stylistics, corpus theory, cognitive psychology, etc. English teaching is a gradual process. Whether English is the first language or not, learning English is crucial in today's rapidly developing globalization.

[0003] However, when teachers teach English, they usually use loudspeakers or follow-up reading devices to assist teachers in teaching English. However, most traditional English follow-up reading devices have simple structures and poor protection. After long-term use, poor heat dissipation can easily lead to overheating of internal components, which can easily affect the normal operation of the device. The sound outlet is easily blocked by dust and floating objects in the air, which can easily affect the sound quality of English follow-up reading. To this end, we provide an English follow-up reading device for English teaching to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to make up for the deficiencies of the prior art and to provide an English follow-up device for English teaching. The device can not only facilitate buffering and protection of the internal components of the device, but also facilitate rapid heat dissipation while slowly scraping off dust at the sound outlet, and can also place the device on a plane at various angles by adsorption.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an English follow-up device for English teaching, comprising a frame, a buffer frame is arranged inside the frame, and an electronic component is installed on the inner wall of the buffer frame, and a buffer component is connected to the electronic component; a protective mechanism is also arranged inside the frame, and the protective mechanism includes a rotating ventilation disk rotatably connected to the inner wall of the frame, and a driving component and a scraping component connected to the rotating ventilation disk, and the protective mechanism also includes a heat dissipation component facing two directions of the electronic component, and a transmission component connected to the driving component and the heat dissipation component.

By setting up the transmission assembly, the second driving sprocket in the transmission assembly rotates synchronously with the rotation of the servo motor output shaft, and the diameter of the second driving sprocket is greater than the diameter of the second driven sprocket, so that when the second driving sprocket rotates slowly, it can drive the second driven sprocket to rotate quickly through the second chain, so that the second chain drives the fan blade group to rotate quickly through the second bevel gear and the first bevel gear, thereby driving the fan blade group to quickly discharge heat from the frame.

By setting the scraper assembly, the scraper assembly can be installed or disassembled on the front side of the frame, and the scraper frame is in contact with the air inlet surface of the rotating vent plate after the scraper assembly is installed, so that the dirt on the surface of the rotating vent plate can be scraped and stored when the rotating vent plate rotates forward, and the dirt can be cleaned by only taking out the scraper assembly later.

[0011] Furthermore, the buffer assembly includes a sleeve fixed to the top wall and the inner bottom wall of the frame, and a sleeve rod sleeved inside the sleeve and connected to the buffer frame.

DETAILED DESCRIPTION

[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0019] As described in the background technology, most traditional English follow-up devices have simple structures and poor protection. After long-term use, the internal components are prone to overheating due to poor heat dissipation, which can easily affect the normal operation of the device. The sound outlet is easily blocked by dust and floating objects in the air, which can easily affect the sound quality of English follow-up. For this reason, this embodiment provides an English follow-up device for English teaching, which can not only facilitate buffering and protection of the internal components of the device, but also facilitate rapid heat dissipation while slowly scraping off the dust at the sound outlet, and can also place the device on a plane at various angles by adsorption.

[0020] See also Figure 1 - Figure 8 This embodiment proposes an English follow-up device for English teaching, including a frame 1, a buffer frame 2 is arranged inside the frame 1, an electronic component installed on the inner wall of the buffer frame 2, and a buffer component connected to the electronic component.

[0021] refer to Figures 1 to 8 The setting of the buffer component can facilitate the protection of electronic components in the electronic assembly, and play a certain protective role for the electronic components when they are hit by external impact or the entire device falls, thereby avoiding direct damage to the electronic components in the electronic assembly when it falls.

[0022] In addition, the data processing body 3, player 4, battery 6, servo motor 505, display 11, and control button 12 in the present invention are all conventional equipment purchased on the market and known to those skilled in the art. The models can be selected or customized according to actual needs. The setting method, installation method, and electrical connection method thereof can be debugged and operated according to the requirements of the instruction manual for those skilled in the art, and will not be described in detail here.

[0023] The electronic component includes a data processing body 3 installed on the inner wall of the buffer frame 2, and a player 4 installed on the inner wall of the buffer frame 2. The electronic component also includes a battery 6 installed on the inner bottom wall of the buffer frame 2, and a charging port 7 installed in a reserved hole on the outer surface of the frame 1. The battery 6 is used to power the electronic component.

[0024] By setting up the electronic component and the player 4 in the electronic component, the player 4 has the recording and playback functions, and by cooperating with the data processing body 3, the data processing body 3 stores and processes the recorded data, so that the recorded voice can be played through the player 4.

[0025] In addition, the battery 6 mainly powers the entire device, so that it can be used when it is not charged and can be used during portability. The charging port 7 is mainly used to charge the battery 6, so that it can facilitate the storage of electrical energy and power supply when the device is in use.

[0026] The bottom surface of the frame 1 is fixedly connected to a rolling ball rod 13 and a first suction cup 14 sleeved on the lower end of the rolling ball rod 13. The rear side surface of the frame 1 is hinged to a support plate 15 and an articulated frame 16 rotatably matched with the outer end of the support plate 15. The bottom surface of the articulated frame 16 is fixedly connected to a second suction cup 17.

[0027] By providing the rolling ball rod 13 , the first suction cup 14 can be conveniently mounted on the convex ball at the lower end of the rolling ball rod 13 , so that the first suction cup 14 can be flexibly changed in position, so that the frame 1 can be adsorbed on a plane by pressing the first suction cup 14 .

[0028] As a supplement, with the angular swing of the support plate 15 and the auxiliary adsorption of the second suction cup 17, the entire device can be stably adsorbed on a plane, so that the entire device can be in a tilted state to play the recorded audio, thereby facilitating voice follow-up during English teaching.

[0029] A protective mechanism 5 is also provided inside the frame 1, and the protective mechanism 5 includes a rotating ventilation disk 503 rotatably connected to the inner wall of the frame 1, and a driving component and a scraping component connected to the rotating ventilation disk 503. The protective mechanism 5 also includes a heat dissipation component in two directions facing the electronic component, and a transmission component connected to the driving component and the heat dissipation component.

[0030] refer to Figures 1 to 8 The setting of the driving component can facilitate the cooperation with the scraping component when the rotating ventilation disk 503 is driven to rotate slowly through the transmission component, so as to slowly scrape off the dirt adsorbed on the air inlet surface of the rotating ventilation disk 503, and can increase the transmission speed of the heat dissipation component through the transmission component, so that the heat dissipation component can quickly discharge the heat in the frame 1.

[0031] The heat dissipation assembly includes a fan blade group 501 installed at two positions on the side of the frame 1, and a first bevel gear 502 fixedly connected to the outer end of the central axis of the fan blade group 501. The reserved holes opened at two positions on the side of the frame 1 are equipped with dust shield plates 5017 for protecting the fan blade group 501.

[0032] By providing a heat dissipation component, the heat dissipation component is used to quickly discharge the heat generated during the operation of the electronic component, thereby preventing the heat from accumulating inside the frame 1 and causing damage to the electronic components and affecting the sound quality during playback.

[0033] In addition, the two fan blade groups 501 are arranged in the same direction of rotation, and the fan blade group 501 includes fan blades and a central axis, so that the two fan blade groups 501 can be driven in opposite directions by the subsequent transmission components to discharge the heat in the frame 1, and when the heat is discharged, new air enters through the rotating ventilation disk 503.

[0034] The driving assembly includes a fixed rod 504 fixed to the outer surface of the rotating ventilation disk 503, and a first driven sprocket 507 fixed to the outer end of the fixed rod 504. The driving assembly also includes a servo motor 505 installed on the inner wall of the frame 1, and a first driving sprocket 506 located on the upper part of the first driven sprocket 507 and fixedly connected to the output end of the servo motor 505. The first driving sprocket 506 and the first driven sprocket 507 are connected to each other through a first chain 508.

[0035] By setting up a driving component, a PLC programmable logic controller is provided in the servo motor 505, so that the rotation speed of the servo motor 505 can be easily controlled through subsequent control components, and then the heat dissipation rate of the heat in the frame 1 and the rotation speed of the rotating ventilation disk 503 can be adjusted, so that the rotating ventilation disk 503 can cooperate with the scraping component when rotating to scrape off the dust or floating objects adsorbed on the air inlet surface of the rotating ventilation disk 503.

[0036] In addition, the output shaft of the servo motor 505 drives the first driving sprocket 506 to rotate, so that the first driving sprocket 506 drives the first driven sprocket 507 to rotate synchronously through the first chain 508, so that the first chain 508 can drive the rotating ventilation disk 503 to rotate under the limiting action of the frame 1 through the fixed rod 504, so that the rotating ventilation disk 503 can cooperate with the scraping component in a fixed position, so that the scraping component can scrape the dirt on the air inlet surface of the rotating ventilation disk 503.

[0037] The transmission assembly includes a rotating rod 5010 rotatably connected to the inner wall of the frame 1, and a second bevel gear 5011 fixed to the outer surface of the rotating rod 5010 and meshing with the first bevel gear 502. The transmission assembly also includes a second driven sprocket 5012 fixed to the outer surface of the rotating rod 5010, and a second driving sprocket 509 fixed to the outer surface of the output shaft of the servo motor 505. The second driving sprocket 509 is connected to the second driven sprocket 5012 through a second chain 5013.

[0038] By setting up a transmission component, the second driving sprocket 509 in the transmission component rotates synchronously with the rotation of the output shaft of the servo motor 505, and the diameter value of the second driving sprocket 509 is greater than the diameter value of the second driven sprocket 5012, so that when the second driving sprocket 509 rotates slowly, it can drive the second driven sprocket 5012 to rotate quickly through the second chain 5013, and the second chain 5013 can drive the fan blade group 501 to rotate quickly through the second bevel gear 5011 and the first bevel gear 502, thereby driving the fan blade group 501 to quickly discharge the heat in the frame 1.

[0039] In addition, the transmission of the two second bevel gears 5011 meshing with the first bevel gear 502 on the same side can make the rotation directions of the two fan blade groups 501 opposite, so that the air outlet directions of the two fan blade groups 501 themselves can be set in opposite directions, so that both fan blade groups 501 can discharge the heat in the frame 1.

[0040] The scraping assembly includes a protective ventilation plate 5014 installed in the reserved hole on the front side of the frame 1, and the rear side of the protective ventilation plate 5014 is fixedly connected to a connecting rod 5015, and the outer end of the connecting rod 5015 is fixedly connected to a scraping frame 5016 for scraping and storing dirt on the surface of the rotating ventilation plate 503.

[0041] By setting up a scraping component, the scraping component can be installed or removed on the front side of the frame 1, and after the scraping component is installed, the scraping frame 5016 is in contact with the air inlet surface of the rotating vent disk 503, so that when the rotating vent disk 503 rotates forward, the dirt on the surface of the rotating vent disk 503 can be scraped and stored, and the dirt can be cleaned by only taking out the scraping component later.

[0042] In addition, after the dirt is scraped off, it can avoid the situation where the dirt blocks the rotating ventilation disk 503, affecting the sound propagation and air intake efficiency, thereby greatly improving the service life of the components in the frame 1 and avoiding a large amount of heat accumulation due to the blockage of the rotating ventilation disk 503.

[0043] The buffer assembly includes a sleeve 8 fixed to the inner top wall and the inner bottom wall of the frame 1, and a sleeve rod 9 sleeved inside the sleeve 8 and connected to the buffer frame 2. The buffer assembly also includes a telescopic spring 10 sleeved on the outer surface of the sleeve rod 9 and located outside the sleeve 8.

[0044] By providing a buffer assembly, it is convenient to buffer the electronic components in the electronic assembly, avoiding hard collision damage to the electronic components when external impact or the device falls. The buffer assembly can play a certain buffering role and reduce the risk of damage to the electronic components in the electronic assembly.

[0045] In addition, when the entire device is subjected to external impact, the telescopic spring 10, the sleeve rod 9 and the sleeve 8 can play a certain buffering role under the telescopic action, thereby ensuring the safety of the electronic components in the buffer frame 2 to the greatest extent.

[0046] A display 11 and a control button 12 are installed on the front of the frame 1 , and a handle 18 is fixedly connected to the upper surface of the frame 1 , as well as a shoulder strap 19 rotatably connected to the outer surface of the frame 1 .

[0047] By setting the display 11, the information transmitted in the electronic component can be displayed conveniently, so that the teacher can observe the recording or playing status and progress. The setting of the control button 12 can facilitate the control of the entire device.

[0048] As a supplement, the PLC programmable logic controller is adopted, such as Siemens S7-1200 series or Mitsubishi FX3U series, and the specific model is selected according to actual needs. The controller has powerful data processing capabilities and multiple input and output interfaces, suitable for complex control environments.

[0049] Working principle: When using the English follow-up reading device in English teaching, firstly, the follow-up reading device is hung on the body through the shoulder strap 19 or the follow-up reading device is pressed and adsorbed onto a plane through the first suction cup 14 and the second suction cup 17, and the angle of adsorption on the plane can be adjusted to facilitate the playback of voice.

[0050] Thus, the control button 12 can start the data processing body 3 and the player 4 in the electronic component to record the sound or directly transmit and play the voice, so that the teacher can amplify the sound and follow the reading when teaching English.

[0051] When teaching English, the servo motor 505 can be started by the control button 12, and the output shaft of the servo motor 505 drives the second active sprocket 509 to rotate forward, so that the second active sprocket 509 drives the second driven sprocket 5012 and the rotating rod 5010 to rotate through the second chain 5013, so that the rotating rod 5010 is meshed with the first bevel gear 502 through the second bevel gear 5011, so that the first bevel gear 502 drives the fan blade group 501 to rotate rapidly, so that the fan blade group 501 can continue to twist the electronic components in the frame 1 to dissipate heat rapidly, and at the same time of rapid heat dissipation, it can The servo motor 505 drives the first active sprocket 506 to rotate, and the first active sprocket 506 drives the first driven sprocket 507 and the fixed rod 504 to rotate slowly through the first chain 508, so that the fixed rod 504 can drive the rotating ventilation disk 503 to rotate, so that the rotating ventilation disk 503 can be contacted and scraped by the scraping frame 5016, and the dirt adsorbed on the air inlet surface of the rotating ventilation disk 503 is scraped and collected, so that the electronic components in the frame 1 can be quickly cooled, and the sound outlet of the rotating ventilation disk 503 can be scraped to prevent blockage and affect the sound quality of the playback.

[0052] To clean the dirt after scraping, it is only necessary to take out the protective ventilation plate 5014 from the frame 1 and take out and clean the dirt in the scraping frame 5016.
