Description

Technical Field

[0001] The present invention relates to the technical field of intelligent popular science teaching aids, and in particular to a popular science teaching aid for medicine and food homologous substances. Background Art

[0002] In the field of medical health, the concept of medicine and food homology integrates traditional Chinese medicine and modern nutrition, and plays a key role in disease prevention, postoperative rehabilitation, and chronic disease management, and its application value is becoming increasingly prominent. However, the popular science teaching aids currently used to popularize the knowledge of medicine and food homology have many deficiencies in terms of technology, and it is difficult to meet the complex, diverse and dynamically changing popular science needs of hospitals. For example: At present, the popular science teaching aids for the knowledge of medicine and food homology in hospitals are mainly display cabinets or rolling display screens; display cabinets are used to display certain samples of medicine and food homology substances and are accompanied by text descriptions, and are usually large in size; rolling screens display pictures and effects of medicine and food homology substances through electronic screens, and are usually installed in hospital corridors, halls and other places. The above two popular science teaching aids still have the following technical problems in actual use:

[0003] 1. Inconvenient movement leads to poor convenience and flexibility: During ward rounds, it is difficult for medical staff to carry the display cabinet to the patient's bedside for detailed explanations; and for patients in the department, it is impossible to obtain popular science information in the display cabinet in a timely and convenient manner. Patients are often required to go to designated locations to check on their own, which undoubtedly increases the patient's mobility and learning burden.

[0004] 2. The effect of patients viewing the popular science content on the display cabinet or scrolling screen by themselves is not good: on the one hand, the information presentation form on the display cabinet and scrolling screen is relatively simple, mostly static text and pictures, which is difficult to attract the attention of patients and stimulate their interest in in-depth understanding of the knowledge of medicine and food homology; on the other hand, the information in the display cabinet is diverse and complicated, and patients cannot find the medicine and food homology substances or dietary formulas suitable for their diseases in a timely and rapid manner. For the scrolling screen, they need to read all the information before they can see the medicine and food homology materials they need, which greatly reduces the actual effect of popular science.

[0005] With the continuous refinement and diversification of medical services, higher requirements are placed on the convenience, pertinence and interactivity of the popular science tools for the knowledge of the homology of medicine and food. For example: when training medical staff, a tool that can flexibly display the application of the knowledge of the homology of medicine and food in different departments is needed to help medical staff better master the relevant knowledge and improve their business capabilities. For patients in different departments, they hope to have popular science content specifically targeted at the characteristics of their diseases, so that they can quickly obtain relevant information on the homology of medicine and food and carry out scientific diet conditioning. When making rounds in the inpatient ward, medical staff urgently need a tool that is easy to carry and easy to operate, which can provide personalized dietary advice and guidance to patients recovering from surgery at any time. At the same time, the popular science tools placed in the hospital corridors should also be attractive and practical enough to allow passing patients to easily acquire knowledge and improve the effect of popular science.

[0006] To sum up, the existing popular science display cabinets and scrolling screens on the homology of medicine and food can no longer meet the diverse popular science needs of hospitals. It is urgent to develop a new, convenient, flexible and targeted popular science teaching aid on the homology of medicine and food to solve the various problems existing in the current popular science methods and better serve the training of medical staff and the popular science work of patients. Summary of the invention

[0007] The present invention aims to provide a popular science teaching aid for medicinal and edible homologous substances to solve the technical problems that existing popular science tools are large in size, inconvenient to move, poor in convenience and flexibility of use, and poor pertinence of popular science, resulting in unsatisfactory popular science effects.

[0008] In order to achieve the above object, the present invention adopts the following technical scheme:

[0009] A popular science teaching aid for food-medicine homologous substances comprises a movable main body, wherein a plurality of installation areas are arranged on the upper part of the main body, each installation area is classified according to departments or disease types, and a smart screen for popular science education is detachably arranged in each installation area, and the smart screen is used to display the food-medicine homologous substances, efficacy and dietary formula corresponding to each installation area; a power supply unit and a controller are arranged inside the main body, and the controller is electrically connected to the plurality of smart screens; an operation area is also arranged below the installation area of ​​the main body, and a plurality of control buttons corresponding to the installation areas are arranged in the operation area, and the control buttons are electrically connected to the controller; when a certain control button is operated, the control button sends a signal to the controller, and the controller is used to control the plurality of smart screens to form a large screen, which is used to display audio-visual materials of the food-medicine homologous substances in the corresponding installation area, otherwise, each smart screen displays the food-medicine homologous substances in its own installation area respectively; the smart screen is a touch screen, and has a power supply and a microcontroller inside.

[0010] The principles and advantages of this solution are:

[0011] 1. By setting up several installation areas on the main body, it is convenient to classify the medicinal and edible substances. In actual use, they can be classified according to departments or disease types. For example, they can be classified according to departments, such as gastroenterology, endocrinology, cardiovascular medicine, etc. according to the placement and location of the installation area. The smart screen set in each installation area is used to display the relevant medicinal and edible substances. For example, the medicinal and edible substances commonly used in gastroenterology include yam and hawthorn, mulberry leaves and bitter melon are used in endocrinology, and salvia miltiorrhiza and kudzu root are used in cardiovascular medicine. This makes it convenient for patients in different departments to quickly view the medicinal and edible substances related to themselves, and to achieve scientific dietary conditioning by conducting popular science specifically targeting the characteristics of their diseases. The pertinence is strong and the popular science effect is better.

[0012] 2. By detachably setting several smart screens on the main body, different application scenarios can be met, with higher flexibility and convenience: for example, the movable main body can be placed in different corridors of the hospital for patients on the corresponding floors to view, or it can be placed at the nurse station on the corresponding floor of the inpatient department for patients in the corresponding area to view, or when medical staff need to be trained, the main body can be moved to the training room to display the application of the knowledge of medicine and food homology in different departments, helping medical staff to better master the relevant knowledge. When it is necessary to conduct corresponding popular science education for patients in separate departments or inpatient wards, the smart screen can be removed from the main body and taken separately for education to the patients. Especially for places with limited space such as diagnosis rooms and inpatient wards, a smart screen is small in size and light in weight, making it more flexible and convenient to use.

[0013] 3. By setting an operation area on the main body and using the control buttons in the operation area, multiple smart screens can be switched to large-screen mode, making it easier for more people to watch; and when one or several smart screens are removed, the control buttons in the operation area can be used to display the medicinal and edible substances in the corresponding areas on the remaining smart screens for users to view. That is, after the smart screen is removed, it will not affect the normal use of the teaching aid, and its functions remain complete and comprehensive.

[0014] 4. The smart screen is a touch screen. By touching, you can choose to view multiple popular science information such as medicinal and edible substances, efficacy, dietary recipes and preparation methods displayed on the smart screen; each smart screen can be displayed separately for different patients to view information related to themselves at the same time, or it can be operated uniformly through control buttons and controllers to form a large screen, displaying information in one area at the same time, for multiple patients to study and view together.

[0015] 5. Reduce maintenance costs: The smart screen is detachable and has its own power supply and microcontroller. When a smart screen fails, it only needs to be removed for repair or replacement. It will not affect the normal operation of other parts of the entire popular science teaching aid, reducing the overall maintenance cost and difficulty, and also reducing the time the teaching aid is out of use due to failure.

[0016] 6. In addition to displaying static medicinal and edible substances, their effects, and dietary formulas, the smart screen can also play dynamic video content, such as a cooking process demonstration video of medicinal and edible ingredients, so that users can more intuitively understand the dietary preparation methods; or display popular science content in the form of animations, vividly explaining the working principles of medicinal and edible substances, and increasing the interest and appeal of popular science. In addition, users can set personalized browsing modes on the smart screen according to their own needs and preferences, such as font size, color, voice broadcast, etc., to facilitate the use of people of different ages and different vision conditions, and meet diverse usage needs.

[0017] Preferably, as an improvement, the bottom of each installation area is provided with a power socket and a bus socket protruding outward, the power socket is electrically connected to the power supply part, and the bus socket is electrically connected to the controller, and the bottom of each smart screen is provided with an interface for cooperating with the power socket and the bus socket; a light board electrically connected to the controller is also provided above each installation area, the light board is used to display the category name of the corresponding installation area, when the smart screen is installed in the installation area, the interfaces on the smart screen are respectively connected to the power socket and the bus socket, when the controller detects that the bus socket is connected, it is used to control the light board on the corresponding installation area to light up, otherwise, the light board in the corresponding installation area is off.

[0018] Beneficial effects:

[0019] 1. By setting a light board electrically connected to the controller above each installation area, the installation status of the smart screen can be intuitively displayed. When the smart screen is correctly installed and connected to the bus socket, the corresponding light board lights up, and the staff and users can know at a glance that the equipment in the installation area is connected normally; if the light board goes out, it indicates that the smart screen is not installed or there is a problem with the connection, which facilitates timely inspection and maintenance, and improves the efficiency and convenience of equipment management.

[0020] 2. By setting a socket in the installation area and an interface at the bottom of the smart screen; when the smart screen is installed in the installation area, the smart screen can be charged and connected to the controller to facilitate overall control of it; in addition, after the socket and the interface are connected, it can also play a certain positioning and fixing role for the smart screen, thereby improving the stability of the smart screen connection.

[0021] 3. By associating the light board with the bus socket, on the one hand, the light board can be automatically started after installation to display the name of the installation area of ​​the display screen. On the other hand, it can be reversed by checking whether the light board is lit and whether there is a fault in the smart screen connection, providing users with clear operation guidance in a visual way.

[0022] Preferably, as an improvement, limiting grooves are provided on both sides of the installation area, electromagnets are provided in the limiting grooves, limiting blocks are provided on both sides of the smart screen, metal sheets are provided on the limiting blocks, and the limiting blocks are slidably connected to the limiting grooves; when the light sign on the corresponding installation area lights up, the controller controls the electromagnet to be energized, and the electromagnet and the metal sheet on the limiting block are fixed by magnetic attraction.

[0023] Beneficial effects: By setting a limit slide in the installation area and limit blocks on both sides of the smart screen, it is convenient to limit and guide the smart screen when it is installed; when the smart screen is installed in place, the controller first controls the light board to light up, and then controls the electromagnet to be energized. At this time, the electromagnet and the metal sheet on the limit block are fixed by magnetic attraction; the popular science teaching aids can be prevented from being bumped or collided during the movement, which is beneficial to enhance the overall stability of the equipment and reduce the probability of failure caused by looseness.

[0024] Preferably, as an improvement, an unlocking area is also provided on the main body, and any one of password unlocking, fingerprint unlocking and face unlocking is provided in the unlocking area. When the controller recognizes that the unlocking area is unlocked, it is used to control the electromagnet to cut off power.

[0025] Beneficial effect: By setting an unlocking area on the main body, the anti-theft function can be achieved. Only authorized medical staff can unlock it. After successful unlocking, the electromagnet is powered off and loses its magnetic attraction, making it easy to remove the smart screen from the main body and use it separately as a popular science teaching aid, which is beneficial to improve the safety of use.

[0026] Preferably, as an improvement, a vertical groove connected to the limit slide is further provided on the side wall of the limit slide, an elastic member is provided in the vertical groove, the bottom of the elastic member is fixed on the bottom wall of the vertical groove, a pressure block is provided on the top of the elastic member, one end of the pressure block extends into the limit slide, and is slidably connected with the limit slide and the vertical groove; when the limit blocks on both sides of the smart screen are inserted into the limit slide, the bottom of the limit block is against the pressure block and pushes the pressure block to move downward to compress the elastic member, and when the electromagnet is powered off, the smart screen loses its fixing function and slides upward under the action of the elastic member.

[0027] Beneficial effects: The sliding connection design between the pressing block and the limiting slide and vertical groove, as well as the buffering and assisting effect of the elastic part, means that when the smart screen needs to be disassembled, the electromagnet only needs to be powered off, and the elastic part will rebound quickly, pushing the pressing block upward, thereby driving the smart screen to slide upward; this process does not require manual effort to pull the smart screen out of the tightly fitting limiting slide, greatly reducing the difficulty of disassembly and improving operating efficiency. In addition, since the elastic part has a buffering and assisting effect, it is helpful to reduce the impact force of the smart screen on the limiting slide, electromagnet and other components during the installation and disassembly process. At the same time, the provision of the elastic part is helpful for the operator to sense the downward pressure of the smart screen during installation, avoiding direct downward sliding due to excessive pressure causing damage to the socket below.

[0028] Preferably, as an improvement, an upper limit switch and a lower limit switch electrically connected to the controller are further provided in the limit slide slot; a storage box is further provided behind the light board, the storage box is fixed above the installation area, a reel and a micro motor for driving the reel to rotate are provided in the storage box, and the micro motor is electrically connected to the controller; a shielding cloth is curled on the reel, and a QR code is provided on the shielding cloth; when the smart screen is installed in the installation area, the limit block abuts against the pressure block, and the pressure block triggers the lower limit switch, at this time, the controller controls the reel to rotate so that the shielding cloth is curled and collected in the storage box, when the smart screen is taken out from the installation area, the limit block loses the force on the pressure block, and the pressure block moves upward under the action of the spring and triggers the upper limit switch, at this time, the upper limit switch sends a signal to the controller, and the controller is used to control the reel to rotate and release the shielding cloth, so that the shielding cloth is located at the display window of the installation area.

[0029] Beneficial effects:

[0030] 1. The connection between the upper limit switch and the lower limit switch and the controller realizes the accurate monitoring of the installation status of the smart screen. Through this automated detection method, the controller can timely and accurately control the micro motor according to the switch signal, and then control the retraction and extension of the shielding cloth. When the smart screen is installed in the installation area, the shielding cloth is retracted, which does not affect the normal display of the smart screen; when the smart screen is taken out, the shielding cloth is automatically unfolded to prevent dust and other pollutants from entering the installation area and protect the internal electronic components and interfaces.

[0031] 2. By setting a QR code on the shielding cloth, more interactive channels are provided for users; users can obtain information about medicinal and edible substances by scanning the QR code, for example: by scanning the code to view relevant videos about medicinal and edible substances in the corresponding installation area for learning, thereby improving the popular science effect; in addition, when the smart screen is disassembled, the patient can choose to view it on the remaining smart screens, or scan the QR code on the shielding cloth to view it on the mobile phone, making the popular science education methods more diverse.

[0032] Preferably, as an improvement, a printer is also provided on the main body, and the printer is used to print a dietary formula of a combination of medicine and food homologous substances.

[0033] Beneficial effect: By setting up a printer, when a patient is interested in a dietary formula of a certain medicinal and edible substance, the dietary formula can be directly printed out through the printer, which is conducive to further improving the effect of popular science education.

[0034] Preferably, as an improvement, a protective cover is provided outside the smart screen, a handle is provided on the top of the protective cover, and limit blocks are provided on both sides of the protective cover, and the limit blocks are made of metal material.

[0035] Beneficial effects: The protective cover protects the smart screen, and the handle makes it easy to take the smart screen out of the installation area.

[0036] Preferably, as an improvement, the controller also includes a management module, which is used to set and determine the lending time of the smart screen. When the upper limit switch trigger time exceeds the preset lending time, the management module sends a signal to the controller. After receiving the signal, the controller sends a reminder signal to the lent smart screen and the management terminal to remind the user to return the smart screen on time.

[0037] Beneficial effect: By setting up a management module and associating it with the upper limit switch, when the upper limit switch is in the triggered state for a long time and exceeds the preset lending time, it means that the smart screen has not been returned to the corresponding installation area according to the lending time. At this time, the controller can send a reminder message to the user based on this situation by connecting with the smart screen or management terminal, informing the user to return the device in time, thereby reducing the risk of equipment loss, damage, etc. due to forgetting to return the device, and reducing the difficulty and complexity of equipment management.

[0038] Preferably, as an improvement, a feedback module electrically connected to the microcontroller is also provided in the smart screen. When the user receives the reminder signal, the feedback module pops up in the smart screen and displays delayed borrowing and on-time return options for the user to choose. After the user makes a selection, the microcontroller sends a signal to the controller and the management terminal.

[0039] Beneficial effects: The delayed borrowing and on-time return options provided by the feedback module add flexibility to equipment management; if the user does have a reasonable need to extend the usage time, after selecting delayed borrowing, the controller and management terminal can receive the information in time and adjust the loan time record accordingly to avoid repeated reminders due to timeouts. At the same time, it can also ensure that the equipment lending arrangement is more in line with actual usage and improve management efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Embodiment 1

[0054] like Figure 1-2As shown, a popular science teaching aid for medicine and food homologous substances includes a movable body 1, and a plurality of installation areas 11 are arranged on the upper part of the body 1. Each installation area 11 is classified according to the department or disease type, and a smart screen 2 for popular science education is detachably arranged in each installation area 11; specifically, the front and top openings of the installation area 11 are arranged to facilitate the installation of the smart screen 2 into the structure from the top; the smart screen 2 is used to display popular science information such as medicine and food homologous substances, efficacy and dietary formula corresponding to each installation area 11. For example: according to the placement and location of the installation area 11, it can be divided into gastroenterology, endocrinology, cardiovascular medicine, etc., and the smart screen 2 arranged in each installation area 11 is used to display relevant medicine and food homologous substances, for example: the medicine and food homologous substances commonly used in gastroenterology include yam, hawthorn, etc., mulberry leaves and bitter melon are used in endocrinology, and salvia miltiorrhiza, kudzu root, etc. are used in cardiovascular medicine.

[0055] In this embodiment, the smart screen 2 is a touch screen, which has a power supply and a microcontroller inside. By touching the corresponding area of ​​the medicinal and edible substances displayed on the smart screen 2, you can further view the efficacy, dietary formula and manufacturing method of the substance. In addition to displaying static medicinal and edible substances, efficacy and dietary formulas, the smart screen 2 in this embodiment can also play dynamic video content, such as a cooking process demonstration video of medicinal and edible ingredients, so that users can understand the dietary preparation method more intuitively; or display popular science content in the form of animation, vividly explaining the working principle of medicinal and edible substances, and improving the interest and attractiveness of popular science.

[0056] The body 1 is also provided with a power supply unit and a controller 6, which is electrically connected to the plurality of smart screens 2. The power supply unit includes a power supply and a power cord. Specifically, an electric control box is provided at the lower part of the body 1, and the power supply unit and the controller 6 are provided in the electric control box; a universal wheel 100 is provided at the bottom of the body 1 to facilitate the movement of the body 1. Figure 1 As shown, the main body 1 is located below the installation area 11 and is also provided with an operation area 3, in which a number of control buttons 31 corresponding to the installation areas 11 are provided, and the control buttons 31 are electrically connected to the controller 6; when a certain control button 31 is operated, the control button 31 sends a signal to the controller 6, and the controller 6 is used to control a number of smart screens 2 to form a large screen for displaying audio-visual materials of the medicinal and edible substances in the corresponding installation area 11, otherwise, each smart screen 2 displays the medicinal and edible substances in its respective installation area 11.

[0057] Specifically, the controller 6 is electrically connected to several smart screens 2 via data cables (such as HDMI cables, DisplayPort cables, etc.), and the control buttons 31 in the operation area 3 are connected to the controller 6 via control cables, usually using RS-485 bus or CAN bus. When in use, the control button 31 at the corresponding position is operated, and the controller 6 identifies and judges the information, and uses the screen splicing software to combine multiple independent smart screens 2 into a logically large screen for multiple patients to view and study together. In this embodiment, combining multiple smart screens 2 into a large screen belongs to the prior art. For example, NVIDIA Mosaic screen splicing software is used to splice multiple NVIDIA graphics card-driven smart screens 2 to achieve seamless display, which will not be described in detail here.

[0058] like Figure 2 As shown, when one or more of the smart screens 2 are removed, the control buttons 31 in the operation area 3 can make the medicinal and edible substances in the corresponding area displayed on the remaining smart screens 2 for the convenience of users to view. That is, after the smart screen 2 is removed, it will not affect the normal use of the teaching aid, and its functions are still complete and comprehensive. And each smart screen 2 can be used alone on the main body 1 or removed for use. For example, when it is necessary to conduct corresponding popular science education for patients in separate departments or inpatient wards, the smart screen 2 can be removed from the main body 1 and taken out separately for education of the patients. Especially for places with limited space such as diagnosis rooms and inpatient wards, a smart screen 2 is small in size and light in weight, which is convenient for mobile education and more flexible and convenient to use.

[0059] The bottom of each installation area 11 is provided with a power socket 111 and a bus socket 112 protruding outward. The power socket 111 is electrically connected to the power supply unit for charging a separate smart screen 2. The bus socket 112 is electrically connected to the controller 6. The bottom of each smart screen 2 is provided with an interface for matching with the power socket 111 and the bus socket 112. By providing a socket in the installation area 11 and an interface at the bottom of the smart screen 2; when the smart screen 2 is installed in the installation area 11, the smart screen 2 can be charged and connected to the controller 6, so that the controller 6 can control it overall; in addition, after the socket is connected to the interface, it can also play a certain positioning and fixing role for the smart screen 2, thereby improving the stability of the connection of the smart screen 2.

[0060] like Figure 1 , Figure 6As shown, a light board 4 electrically connected to the controller 6 is also provided at the upper front of each installation area 11. The light board 4 is used to display the classification name of the corresponding installation area 11. When the smart screen 2 is installed in the installation area 11, the interfaces on the smart screen 2 are respectively connected to the power socket 111 and the bus socket 112. When the controller 6 detects that the bus socket 112 is connected, it is used to control the light board 4 on the corresponding installation area 11 to light up. Otherwise, the light board 4 of the corresponding installation area 11 is off. By providing a light board 4 electrically connected to the controller 6 above each installation area 11, the installation status of the smart screen 2 can be intuitively displayed; when the smart screen 2 is correctly installed and connected to the bus socket 112, the corresponding light board 4 lights up, and the staff and users can know at a glance that the equipment connection in the installation area 11 is normal; if the light board 4 is off, it indicates that the smart screen 2 is not installed or there is a problem with the connection, which is convenient for timely inspection and maintenance, and improves the efficiency and convenience of equipment management.

[0061] The installation area 11 is also provided with a limit slot 12 on both sides, and an electromagnet 121 is provided in the limit slot 12; Figure 3-4 As shown, limit blocks 21 are arranged on both sides of the smart screen 2, metal sheets are arranged on the limit blocks 21, and the limit blocks 21 are slidably connected with the limit slide grooves 12; when the light board 4 on the corresponding installation area 11 lights up, the controller 6 controls the electromagnet 121 to be energized, and the electromagnet 121 and the metal sheet on the limit blocks 21 are fixed by magnetic attraction. Specifically, in this embodiment, a protective cover is also arranged outside the smart screen 2, and a handle 22 is arranged on the top of the protective cover. The limit blocks 21 are arranged on both sides of the protective cover, and the limit blocks 21 are made of metal material.

[0062] By setting a limiting groove 12 in the installation area 11 and setting limiting blocks 21 on both sides of the smart screen 2, it is convenient to limit and guide the smart screen 2 when installing it; when the smart screen 2 is installed in place, the controller 6 first controls the light sign 4 to light up, and then controls the electromagnet 121 to be energized. At this time, the electromagnet 121 and the metal sheet on the limiting block 21 are fixed by magnetic attraction; the popular science teaching aids can be prevented from being bumped or collided during the movement, which is beneficial to enhance the overall stability of the equipment and reduce the probability of failure caused by looseness.

[0063] In this embodiment, the main body 1 is also provided with an unlocking area (not shown in the figure), and any one of password unlocking, fingerprint unlocking, and face unlocking is provided in the unlocking area. The above unlocking methods are prior arts and will not be described in detail here; when the controller 6 recognizes that the unlocking area is unlocked, it is used to control the electromagnet 121 to cut off the power. By setting the unlocking area on the main body 1, the anti-theft function can be realized, and only authorized medical personnel can unlock it. After the unlocking is successful, the electromagnet 121 is powered off and loses its magnetic attraction, which makes it easy to remove the smart screen 2 from the main body 1 and use it separately as a popular science teaching aid, which is conducive to improving the safety of use.

[0064] Better as Figure 5 As shown, in this embodiment, the side wall of the limiting slide groove 12 is also provided with a vertical groove 13 connected thereto, and an elastic member 131 is provided in the vertical groove 13. Specifically, the elastic member 131 is a spring; the bottom of the elastic member 131 is fixed on the bottom wall of the vertical groove 13, and a pressing block 132 is provided on the top of the elastic member 131. One end of the pressing block 132 extends into the limiting slide groove 12 and is slidably connected with the limiting slide groove 12 and the vertical groove 13. When the limiting blocks 21 on both sides of the smart screen 2 are inserted into the limiting slide groove 12, the bottom of the limiting blocks 21 abuts against the pressing block 132, and pushes the pressing block 132 to move downward to compress the elastic member 131. When the electromagnet 121 is powered off, the smart screen 2 loses its fixing function, and the smart screen 2 slides upward under the action of the elastic member 131.

[0065] When the smart screen 2 needs to be disassembled, it is only necessary to cut off the power to the electromagnet 121, and the elastic member 131 will rebound quickly, thereby pushing the pressing block 132 upward, driving the smart screen 2 to slide upward; this process does not require manual effort to pull the smart screen 2 out of the tightly fitting limiting slide 12, which greatly reduces the difficulty of disassembly and improves the operating efficiency. In addition, since the elastic member 131 has a buffering and assisting effect, it is helpful to reduce the impact force of the smart screen 2 on the limiting slide 12, the electromagnet 121 and other components during the installation and disassembly process. At the same time, the provision of the elastic member 131 is helpful for the operator to sense the downward pressure of the smart screen 2 during installation, and avoid direct downward sliding due to excessive pressure causing damage to the socket below.

[0068] Embodiment 2

[0069] The difference between this embodiment and the first embodiment is that Figure 7As shown, it also includes an upper limit switch 133 and a lower limit switch 134 electrically connected to the controller 6. Specifically, in this embodiment, the upper limit switch 133 is arranged on the upper side wall of the vertical groove 13, and the lower limit switch 134 is arranged on the lower side wall of the limit slide groove 12. When the elastic member 131 is in a natural state, the pressing block 132 contacts with the upper limit switch 133, and when the elastic member 131 is in a maximum compression state, the pressing block 132 contacts with the lower limit switch 134.

[0070] like Figure 8-9 As shown, a storage box 5 is further provided at the rear of the light board 4, the light board 4 is fixed to the body 1 through a bracket, and the storage box 5 is provided at the rear of the light board 4. Specifically, an installation cavity 50 is provided in the storage box 5, a reel 51 and a micro motor 52 for driving the reel 51 to rotate are provided in the installation cavity 50, and the micro motor 52 is electrically connected to the controller 6; a shielding cloth 53 is curled on the reel 51, and a QR code area 531 is provided on the shielding cloth 53, and the QR code area 531 is used to place the printed QR code photo; an opening for the shielding cloth 53 to pass through is also provided at the bottom of the storage box 5.

[0071] like Fig.10 As shown, when the smart screen 2 is installed in the installation area 11, the limit block 21 slides in the limit slide groove 12 and pushes the pressure block 132 to push the pressure block 132 downward. At this time, the elastic member 131 gradually contracts. When the pressure block 132 moves down to trigger the lower limit switch 134, it means that the smart screen 2 is completely installed and connected to the socket at the bottom of the installation area 11, and is fixed in position under the action of the electromagnet 121. At the same time, since the lower limit switch 134 is triggered, the lower limit switch 134 sends a signal to the controller 6. After receiving the signal, the controller 6 controls the micro motor 52 to rotate, thereby driving the reel 51 to rotate, so that the shielding cloth 53 is curled and collected in the storage box 5. When the smart screen 2 is taken out from the installation area 11, the magnetic attraction between the limit block 21 and the limit slide groove 12 disappears, and the pressure block 132 moves upward under the push of the elastic member 131 and triggers the upper limit switch 133. At this time, the upper limit switch 133 sends a signal to the controller 6. After receiving the signal, the controller 6 controls the micro motor 52 to rotate in the opposite direction, thereby rotating the reel 51 to release the shielding cloth 53, so that the shielding cloth 53 is located at the display window of the installation area 11.

[0072] This embodiment achieves accurate monitoring of the installation status of the smart screen 2 by connecting the upper limit switch 133 and the lower limit switch 134 to the controller 6. Through this automated detection method, the controller 6 can timely and accurately control the micro motor 52 according to the switch signal, thereby controlling the retraction and extension of the shielding cloth 53. Figure 8As shown, when the smart screen 2 is installed in the installation area 11, the shielding cloth 53 is retracted and does not affect the normal display of the smart screen 2; when the smart screen 2 is taken out, the shielding cloth 53 is automatically unfolded to prevent dust and other pollutants from entering the installation area 11 and protect the internal electronic components and interfaces.

[0073] And by setting a QR code on the shielding cloth 53, more interactive channels are provided for users; users can obtain information about medicinal and edible substances by scanning the QR code, for example: by scanning the code to view related videos of medicinal and edible substances in the corresponding installation area 11 for learning, thereby improving the popular science effect; in addition, when the smart screen 2 is disassembled, the patient can choose to view the remaining smart screens 2, or scan the QR code on the shielding cloth 53 to view it on the mobile phone, and the popular science education methods are more diverse.

[0074] Embodiment 3

[0075] The difference between this embodiment and the second embodiment is that Fig.11 As shown, the controller 6 also includes a management module 61, which is used to set and determine the lending time of the smart screen 2. When the trigger time of the upper limit switch 133 exceeds the preset lending time, the management module 61 sends a signal to the controller 6. After receiving the signal, the controller 6 sends a reminder signal to the lent smart screen 2 and the management terminal 7 to remind the user to return the smart screen 2 on time. A feedback module 200 electrically connected to the microcontroller 6 is also provided in the smart screen 2. When the user receives the reminder signal, the feedback module 200 pops up in the smart screen 2 and displays the delayed borrowing and on-time return options for the user to choose. After the user chooses, the microcontroller 6 sends a signal to the controller 6 and the management terminal 7.

[0076] Specifically, when the smart screen 2 is taken out from the installation area 11, the limit block 21 leaves its original position, and under the action of the elastic member 131, the pressure block 132 triggers the upper limit switch 133, and the upper limit switch 133 sends a trigger signal to the controller 6; after the controller 6 receives the signal, the management module 61 starts timing and records the triggering time of the upper limit switch 133. During the timing process, the management module 61 continuously compares the current timing time with the preset lending time. Once the timing time exceeds the preset lending time, the management module 61 immediately generates a reminder signal and sends the signal to the corresponding lending smart screen 2 and the management terminal 7 through the wireless communication module.

[0077] After receiving the reminder signal, the smart screen 2 will follow the preset reminder method, such as popping up a striking return reminder pop-up window on the screen, and playing a voice reminder at the same time, to inform the user to return it on time. After receiving the reminder signal, the management terminal 7 will display the corresponding reminder information on the management software interface, including the number of the loaned smart screen 2, the installation area 11 to which it belongs, the loan time and other detailed information, so as to facilitate the management personnel to follow up in time, ensure that the smart screen 2 is returned on time, reduce the risk of equipment loss and damage caused by forgetting to return, and reduce the difficulty and complexity of equipment management.

[0078] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
