[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 7 To achieve convenient operation, environmental adjustment, improved cultivation efficiency, and time saving, this application provides a multi-functional schoolbag cabinet for students. The multi-functional schoolbag cabinet includes a cabinet body 1, which has multiple layers from top to bottom, with the third layer being a heating layer. A turntable 4 is located in the middle of the heating layer, and heating tubes 3 are symmetrically arranged on both sides of the turntable 4. A second heat insulation plate 8 is provided between the heating tubes 3 and the inner wall of the cabinet body 1, and the heating tubes 3 are fixedly connected to the second heat insulation plate 8. A first heat insulation plate 7 is located above the turntable 4, and the first heat insulation plate 7 is fixedly connected to the inner wall of the cabinet body 1. The bottom of the first heat insulation plate 7 is symmetrically equipped with an exhaust mechanism 60. The exhaust mechanism 60 includes a U-shaped pipe 2, an exhaust pipe 36, and an exhaust fan 37. The exhaust fan 37 is installed at the bottom of the first heat insulation plate 7 and is embedded inside the first heat insulation plate 7. An exhaust pipe 36 is installed at the top of the exhaust fan 37. The exhaust pipe 36 passes through the left and right ends of the first heat insulation plate 7 and extends into the left and right side walls of the cabinet 1. The U-shaped pipe 2 is fixedly connected to the exhaust pipe 36 and the U-shaped pipe 2. The U-shaped pipe 2 is fixedly connected to the side wall of the cabinet 1, and the top of the U-shaped pipe 2 passes through the top of the cabinet 1 and extends outward.

[0026] Based on the above, heat is generated when the heating tube 3 is powered on, and the turntable 4 rotates to heat the food evenly. The first heat insulation plate 7 and the second heat insulation plate 8 isolate the heating layer to prevent heat from being conducted to other storage layers. The exhaust fan 37 installed at the bottom of the first heat insulation plate 7 then exhausts the hot air from the heating layer through the exhaust pipe 36 and the U-shaped pipe 2 into the cabinet. At the same time, the hot air indirectly heats the inside of the cabinet as it flows in the U-shaped pipe, thus achieving moisture prevention.

[0027] Furthermore, the heating tube 3 works in conjunction with the turntable 4 to achieve 360-degree uniform heating, avoiding localized overheating of food. The multi-layer heat insulation board reduces heat loss and improves heating efficiency, while protecting other items in the storage layer. The exhaust fan 37, the air outlet pipe 36, and the U-shaped pipe 2 enable the hot air circulation system to have both heat dissipation and moisture-proof functions, reducing the growth of mold in the cabinet.

[0028] Please see Figures 1 to 6 A spring hinge 40 is fixedly connected to the left side wall of the heating layer of the cabinet 1, and a second cabinet door 20 is fixedly connected to one end of the spring hinge 40. The second cabinet door 20 is opened or closed by the spring hinge 40. A square recessed groove is provided on the left outer side of the second cabinet door 20, and fixing blocks 21 are symmetrically installed on the left and right sides of the recessed groove. A circular umbrella handle-shaped groove is provided on the fixing block 21, and a first slot is provided on both sides of the circular umbrella handle-shaped groove. A buckle 22 is installed in the first slot, and one end of the buckle 22 is hinged to the fixing block 21.

[0029] Based on the above, the second cabinet door 20 is equipped with an automatic closing function through the spring hinge 40, and a fixing block 21 is installed on the second cabinet door. After the umbrella handle is inserted into the circular groove of the fixing block 21, the buckle 22 is flipped to engage the slot, and the umbrella is fixed by mechanical limiting.

[0030] Furthermore, the second cabinet door 20 is automatically closed via spring hinge 40, reducing manual operation and improving ease of use. The snap-on umbrella fixing structure is simple and reliable, preventing the umbrella from slipping off. At the same time, it utilizes the space outside the cabinet door without occupying the internal storage space of the cabinet. Additionally, the second cabinet door is a heated cabinet door, using the residual heat after heating to dry the umbrella.

[0031] Please see Figure 1 A third heat insulation plate 9 is provided below the turntable 4, and the third heat insulation plate 9 is fixedly connected to the inner side wall of the cabinet 1. A first rotating shaft is fixedly connected to the bottom axis of the turntable 4, and the first rotating shaft passes through the top of the third heat insulation plate 9 and extends into the interior of the third heat insulation plate 9 to be fixedly connected to a first helical gear 5. A first motor 6 is provided on one side of the first helical gear 5, and a worm gear is fixedly connected to the output shaft of the first motor 6, and the worm gear meshes with the first helical gear 5. A second partition plate 10 is installed at the bottom of the third heat insulation plate 9, and the second partition plate 10 is fixedly connected to the inner side wall of the cabinet 1.

[0032] Based on the above, after the first motor 6 starts, the worm drives the first helical gear 5 to rotate, which in turn drives the turntable 4 to rotate through the first rotating shaft. The third heat insulation plate 9 isolates the turntable 4 from the space below to prevent heat from being conducted to the next layer. The second partition 10 supports the third heat insulation plate 9 to ensure structural stability.

[0033] Furthermore, the worm gear meshing with the first helical gear provides a self-locking transmission, allowing for precise control of the turntable speed and ensuring uniform heating. The heat insulation plate separates the transmission mechanism from the heating space, preventing high temperatures from affecting motor performance.

[0034] Please see Figures 1 to 4 The cabinet 1 has a third partition 11 located inside the top of the cabinet 1, and the third partition 11 is slidably connected to the left and right inner side walls of the cabinet 1. The third partition 11 is slidably connected to a vertically placed fourth partition, and the bottom of the fourth partition is fixedly connected to the middle of the upper surface of the first heat insulation plate 7, and the top is fixedly connected to the lower surface of the top of the cabinet 1. The third partition 11 is symmetrically provided with moving mechanisms 50 on both sides, and the moving mechanisms 50 can move the third partition 11 up and down. The left side wall of the cabinet 1 is hinged to a first cabinet door 12, and the first cabinet door 12 is located above the second cabinet door 20.

[0035] Based on the above, the moving mechanism 50 drives the third partition 11 to move up and down. Through the cooperation of the third partition 11 and the fourth partition, the upper space of the cabinet is divided into storage areas of adjustable size.

[0036] Furthermore, the third partition is driven by the moving mechanism 50, enabling adjustable partitions to meet the storage needs of items of different sizes, resulting in high space utilization. The fourth partition is fixedly connected to the heat insulation board and the top of the cabinet to ensure the stability of the partition structure and prevent items from falling.

[0037] Please see Figures 1 to 5 The cabinet 1 has a second slot on the inner side of the bottom of the left and right side walls, and a second rotating shaft 28 is provided in the second slot. The second rotating shaft 28 is rotatably connected to the inner side wall of the cabinet 1, and a shoe plate 27 is installed on the second rotating shaft 28. A fixing frame 29 is installed on the upper surface of the shoe plate 27. A third cabinet door 24 is hinged to the bottom of the left side wall of the cabinet 1.

[0038] Based on the above, the shoe plate 27 can be flipped to a horizontal or vertical state via the second pivot 28. When horizontal, it is used to place shoes. After the shoes are placed, the second pivot 28 is pushed to the innermost layer of the shoe cabinet to flip the shoe plate vertically to the ground. The fixing bracket 29 limits the shoes to prevent them from sliding vertically and saves space. When the third cabinet door 24 is closed, the shoe cabinet area can be sealed to keep the cabinet clean.

[0039] Furthermore, the flip-up shoe panel 27 makes flexible use of the space at the bottom of the cabinet, preventing shoes from being exposed. The fixed rack 29 prevents shoes from slipping off, and the third cabinet door 24 can isolate odors and keep the storage environment clean.

[0040] Please see Figures 1 to 4 The cabinet 1 has a sliding groove in its side wall. The moving mechanism 50 includes a second motor 14, a second helical gear 15, a third helical gear 16, a lead screw 17, and a slider 18. The lead screw 17 is located in the middle of the sliding groove. The bottom of the lead screw 17 is rotatably connected to the side wall of the cabinet 1, and the top of the lead screw 17 is fixedly connected to the top of the cabinet 1 through the top of the third helical gear 16. The third helical gear 16 is meshed with the second helical gear 15. The second helical gear 15 is fixedly connected to the output shaft of the second motor 14. The slider 18 is threaded onto the lead screw 17 and is engaged with the sliding groove. The end of the slider 18 is fixedly connected to the end of the third partition 11.

[0041] Based on the above, after the second motor 14 is started, the second helical gear 15 drives the third helical gear 16 to rotate, which drives the lead screw 17 to rotate. When the lead screw 17 rotates, the slider 18 moves up and down along the slide groove, which drives the third partition 11 to rise and fall vertically, thereby realizing the height adjustment of the storage space.

[0042] Furthermore, the second motor 14 drives the lead screw 17 to drive the slider 18 to achieve automatic adjustment of the partition. It is easy to operate, has high adjustment accuracy, and the gear meshing transmission structure is stable. It can bear the weight of the partition and the items and avoid shaking.

[0043] Please see Figures 1 to 6 The spring hinge 40 includes a first leaf 30, a spring 31, a second leaf 32, and a third pivot 33. One end of the second leaf 32 is fixedly connected to the left side wall of the cabinet 1, and one end of the first leaf 30 is fixedly connected to the right side wall of the second cabinet door 20. A spring 31 is provided in the middle of the overlapping position of the first leaf 30 and the second leaf 32. The third pivot 33 passes through the axis of the first leaf 30, the spring 31, and the second leaf 32, and the first leaf 30 is always perpendicular to the second leaf 32 through the spring 31.

[0044] Based on the above, the elastic force of the spring 31 pushes the first leaf 30 and the second leaf 32 to maintain a perpendicular state. When the cabinet door is opened, the spring force drives the second cabinet door 20 to close automatically. The third rotating shaft 33 serves as a fulcrum to ensure that the leaf rotates smoothly and prevent the cabinet door from shaking.

[0045] Furthermore, the spring hinge 40 has a simple and durable structure, and its automatic closing function can prevent the cabinet door from being opened accidentally, improving safety. It does not require an additional power source and relies on a mechanical structure to achieve its function, resulting in low maintenance costs.

[0046] Please see Figures 1 to 7 An array of ventilation units 70 is arranged above the rear side wall of the cabinet 1. The ventilation unit 70 includes a fan 35 and a base 34. The base 34 is fixedly connected to the rear side wall of the cabinet 1, and the fan 35 is rotatably connected to the internal axis of the base 34.

[0047] Based on the above, the fan 35 rotates after being powered on, accelerating the air circulation between the inside of the cabinet and the outside, expelling humid air and odors, and the array of air exchangers 70 enhances the ventilation effect and covers the upper space of the cabinet.

[0048] Furthermore, the active ventilation achieved by the air exchanger 70 effectively reduces the humidity inside the cabinet, and the hot air circulation system further inhibits mold growth. The structure is compact, installed on the rear wall without occupying the front storage space, and the fan is easy to maintain and replace.

[0049] In summary, this multi-functional schoolbag cabinet for students features a multi-layered cabinet body 1, with a heating layer on the third layer. A turntable 4 is located in the center of the heating layer, with heating tubes 3 symmetrically arranged on both sides of the turntable 4. A second heat insulation plate 8 is installed between the heating tubes 3 and the inner wall of the cabinet body 1, providing insulation and securing the heating tubes 3. The turntable 4 rotates to ensure even heating of the food. A first heat insulation plate 7 is installed above the turntable 4 to prevent heat conduction to the upper storage layer. An exhaust fan 37 is installed at the bottom of the first heat insulation plate 7. A vent pipe 36 is installed, and a U-shaped pipe 2 is connected to the vent pipe 36. Hot air is drawn into the pipe by an exhaust fan 37 and guided by the vent pipe 36 to the U-shaped pipe 2. The U-shaped pipe 2 is connected to the left and right side walls of the cabinet 1. Hot air is discharged through the U-shaped pipe 2. At the same time, the hot air flows in the U-shaped pipe and indirectly heats the inside of the cabinet to achieve moisture prevention. Meanwhile, the second cabinet door 20 outside the heating layer can be automatically closed by a spring hinge 40. A fixing block 21 is also installed on the outside of the second cabinet door. After the umbrella handle is inserted into the circular groove of the fixing block 21, it is fastened by the buckle 22 to fix the umbrella. At the same time, the residual heat of the heating layer is used to dry the umbrella.
