Description

Technical Field

[0001] This invention relates to the field of educational information technology equipment, specifically to a dustproof multimedia smart lectern for teaching. Background Technology

[0002] Currently, most multimedia smart lecterns on the market adopt conventional electronic device chassis designs, which have limited dustproof capabilities and suffer from the following technical defects: 1. Insufficient dustproof structure: Traditional lecterns rely on ordinary ventilation holes or simple filters, which are difficult to effectively block fine particles such as chalk dust and fibers, leading to rapid dust accumulation. 2. Conflict between heat dissipation and dust prevention: To ensure heat dissipation, lecterns usually need open air ducts, but this also increases the risk of dust entering. Long-term dust accumulation affects heat dissipation efficiency, creating a vicious cycle. 3. High maintenance costs: Due to insufficient dustproof capabilities, the equipment needs to be frequently disassembled for cleaning or filter replacement, increasing the maintenance burden and affecting the continuity of teaching.

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] according to Figure 1 , Figure 2 , Figure 3 As shown, a dustproof multimedia smart lectern for teaching includes: a lectern body 1, an equipment compartment 2 inside the lectern body 1, an open module compartment 3 at one end of the equipment compartment 2, a tabletop 4 on the top of the lectern body 1, a power supply 5 at the bottom, a glass window 6 corresponding to the equipment compartment 2 on the tabletop 4, a cooling interface 7 and a power supply interface 8 inside the module compartment 3, the power supply interface 8 being electrically connected to the power supply 5; and a multimedia host 9, which is located inside the equipment compartment 2 and electrically connected to the power supply 5, and a display 10 corresponding to the glass window 6. The processor of the multimedia host 9 is equipped with a liquid cooler 11, which is connected to the cooling interface 7 via a circulating liquid pipe; a refrigerator 12, which is adapted to the module compartment 3 and is equipped with a circulating interface 13 that connects to the cooling interface 7, and a control interface 14 that is electrically connected to the power supply interface 8. The refrigerator 12 is equipped with a liquid tank 15 and a circulating pump 16 connected in series with the circulating interface 13. The top of the refrigerator 12 is equipped with a handle 25; and a cooling controller 17 is located on the side of the platform 4 corresponding to the module compartment 3 and is electrically connected to the power supply interface 8.

[0017] This invention's dustproof multimedia smart lectern for teaching effectively solves the contradiction between dust prevention and heat dissipation in traditional lecterns through an innovative liquid cooling system and modular design. The multimedia host 9's processor uses a liquid cooler 11 instead of traditional air cooling, connected to an external, detachable chiller 12 via a circulating liquid pipe. The chiller 12 forms a closed-loop circulation with the host liquid cooler 11 through the cooling interface 7 of the module compartment 3. The coolant absorbs heat and is actively dissipated by the chiller 12, completely preventing dust from entering the equipment compartment 2 through the cooling duct. The equipment compartment 2 is separated from the module compartment 3, with the multimedia host 9 enclosed in the ventilation-free equipment compartment 2, interacting only with the tabletop 4 through a glass window 6, physically isolating it from dust. The chiller 12, as an independent module, can be quickly installed / maintained via pluggable cooling interfaces 7 and power interfaces 8, reducing the frequency of compartment opening and closing. The cooling controller 17 monitors the temperature in real time and adjusts the power of the chiller 12 to ensure a balance between heat dissipation efficiency and energy consumption. Both the cooling interface 7 and the circulation interface 13 adopt a self-sealing structure design, similar in principle to an oil pipe structure, thus preventing leakage during disconnection and connection. This design eliminates the ventilation holes required for traditional air cooling, and the equipment compartment 2 is completely sealed, preventing the intrusion of chalk dust, fibers, and other particles, significantly extending the equipment's lifespan. Simultaneously, the liquid cooling system directly dissipates heat from the high-heat processor, achieving higher efficiency than air cooling, and eliminates the need for open air ducts, fundamentally solving the vicious cycle of "heat dissipation requires openings, which easily accumulate dust." The chiller 12 can be independently disassembled and maintained, eliminating the need for frequent cleaning of dust inside the main unit; the demand for easily damaged parts such as filters is reduced, lowering the maintenance burden. The modular design allows for quick replacement of the chiller 12, and maintenance can be performed without stopping the main body of the lectern 1, minimizing the impact on teaching.

[0018] The top of the module compartment 3 is provided with an electromagnetic lock block 18, and the refrigeration unit 12 is provided with a locking tongue 19 corresponding to the electromagnetic lock block 18. The electromagnetic lock block 18 is electrically connected to the cooling controller 17.

[0019] This design adds an electromagnetic locking block 18 to the top of the module compartment 3, which cooperates with the locking tongue 19 of the refrigerator 12 and is controlled in conjunction with the cooling controller 17, further optimizing dustproof safety and modular maintenance efficiency. When the refrigerator 12 is inserted into the module compartment 3 and the cooling interface 7 and power supply interface 8 are connected, the cooling controller 17 sends a signal to activate the electromagnetic locking block 18, causing it to engage the locking tongue 19 and secure the refrigerator 12 inside the module compartment 3, preventing accidental detachment. When a power-off signal is actively sent by the cooling controller 17, the electromagnetic locking block 18 releases the locking tongue 19, allowing the refrigerator 12 to be pulled out, ensuring that unauthorized personnel cannot disassemble it arbitrarily. The opening and closing of the electromagnetic locking block 18 is linked to the operating status of the refrigerator 12, preventing forced disassembly that could lead to coolant leakage or equipment damage. This design enhances equipment safety, preventing the refrigerator 12 from falling off due to vibration, accidental contact, or curious operation by students, protecting precision interfaces from physical damage, and reducing the risk of failure. Furthermore, the electromagnetic locking block 18 ensures a tight fit between the refrigerator 12 and the module compartment 3, reducing gaps at the interface and preventing external dust from seeping into the equipment compartment 2 from the edges of the module compartment 3. Unlocking permissions are centrally managed via the cooling controller 17, allowing only authorized personnel to maintain the refrigerator 12, preventing unprofessional operations from affecting system stability. This design is particularly suitable for lecterns requiring high-frequency maintenance or operating in complex environments, significantly improving reliability and management efficiency while ensuring ease of use.

[0020] The liquid tank 15 is provided with a reflux port 20 at the top and is connected to the inlet of the circulation pump 16 at the bottom. The outlet 21 of the circulation pump 16 and the reflux port 20 are respectively connected to the circulation interface 13. A semiconductor cooler 23 is attached to one side of the liquid tank 15. A heat sink 22 is provided on the outside of the semiconductor cooler 23. The semiconductor cooler 23, the heat sink 22 and the circulation pump 16 are respectively electrically connected to the control interface 14.

[0021] This design combines a liquid cooling circulation system with semiconductor refrigeration technology to further optimize heat dissipation efficiency and temperature control accuracy, while maintaining modular dustproof characteristics. The circulation pump 16 draws coolant from the bottom of the liquid tank 15, pumps it through the outlet 21 into the circulation interface 13, and flows to the liquid cooler 11 of the multimedia host 9 to absorb processor heat. The high-temperature coolant returns to the top of the liquid tank 15 through the return port 20, forming a closed-loop circulation. The returning high-temperature liquid flows in from the top of the liquid tank 15, while the low-temperature liquid is pumped out from the bottom, utilizing natural thermal convection to improve heat dissipation efficiency. The semiconductor refrigeration system actively cools the liquid tank 15; its cold end directly cools the coolant inside the tank 15 when powered on, while the hot end dissipates heat to the environment through the external heat sink 22. The cooling controller 17 dynamically adjusts the power of the semiconductor cooler 23 and the speed of the circulation pump 16 through the control interface 14, optimizing cooling efficiency in real time according to the processor load. The thermoelectric cooler 23 can respond quickly to temperature changes, directly cooling the coolant in the liquid tank 15. This is faster than traditional air cooling or passive liquid cooling, making it particularly suitable for sudden high-load processor scenarios. The thermoelectric cooler 23 only activates when needed. Combined with the layered liquid tank 15 design, it reduces the continuous high-load operation of the circulation pump 16, lowering energy consumption and operating noise, thus making it suitable for quiet classroom environments. The thermoelectric cooler 23 is integrated with the liquid tank 15, eliminating the need for external compressors or other large components, keeping the cooler 12 compact and easy to plug and maintain.

[0022] The refrigerator 12 has telescopic rods 24 arranged longitudinally on both sides. The handle 25 is connected between the tops of the two telescopic rods 24. Each telescopic rod 24 has a drag wheel 26 at its bottom. The top of the refrigerator 12 has a liquid inlet 27 corresponding to the liquid tank 15, the bottom has a liquid outlet 28 corresponding to the liquid tank 15, and the side has a vent corresponding to the radiator 22.

[0023] This design, through the integration of a telescopic rod 24, casters 26, a coolant inlet 27, a coolant drain outlet 28, and a side vent, further optimizes the portability, maintenance convenience, and heat dissipation efficiency of the chiller 12, while maintaining its core advantages of dustproofing and modularity. The coolant inlet 27, located at the top, allows for direct coolant injection without disassembly, and works quickly with the return port 20 of the coolant tank 15. The drain outlet 28, located at the bottom, allows for the discharge of old coolant or system cleaning via a valve, eliminating the need to flip the equipment for maintenance. The vent faces the radiator 22 of the semiconductor cooler 23, forming a directional airflow channel. The radiator 22 fan drives the efficient removal of waste heat from the hot end, while a dust filter prevents external dust from entering. The towable design adapts to various mobility needs in classrooms, corridors, and other scenarios, such as sharing the chiller 12 across classes or sending it for repair.

[0024] The module compartment 3 is provided with a longitudinal slide 29 and a protective door 20 that cooperates with the longitudinal slide 29. The top of the protective door 20 covers the cooling interface 7 and the power supply interface 8. A pedal 31 is hinged to the bottom of the module compartment 3. The free end of the pedal 31 is hinged to the bottom of the protective door 20 through a connecting rod 32.

[0025] This design, through the coordinated action of the longitudinal slide rail 29, the protective door 20, and the linkage mechanism of the pedal 31 and the linkage 32, further enhances the dust protection, ease of operation, and interface safety of the module compartment 3. After the refrigeration unit 12 is pushed into the module compartment 3, the pedal 31 is pressed down, and the linkage 32 mechanism pulls the protective door 20 down along the longitudinal slide rail 29, exposing the cooling interface 7 and the power supply interface 8. At this time, the circulation interface 13 and the control interface 14 can be smoothly connected.

[0026] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
