[0026] 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.
[0027] Please see Figures 1-4 The present invention provides a power management IC device with good ventilation, including a device housing 1 and a second dustproof plate 15. The second dustproof plate 15 is installed inside the device housing 1. One end of the device housing 1 is provided with an air inlet assembly, and the other end of the device housing 1 is provided with an exhaust assembly.
[0028] The air intake assembly includes a slot 7, an annular frame 6, a cylindrical tube 8, and a second annular cover plate 14. The annular frame 6 is fixed to the periphery of the slot 7. The cylindrical tube 8 is inserted into the slot 7. The front end of the cylindrical tube 8 is provided with a first annular cover plate 9. The first annular cover plate 9 is fastened to the annular frame 6 and threadedly connected to the annular frame 6. The front end of the first annular cover plate 9 is provided with an annular limiting frame 16. The second annular cover plate 14 is fastened to the annular limiting frame 16 and threadedly connected to the annular limiting frame 16. The second annular cover plate 14 is provided with a second dustproof plate 15. A micro motor 10 is fixedly installed inside the cylindrical tube 8. The output end of the micro motor 10 is provided with a fan blade 12.
[0029] The exhaust assembly includes an air outlet, a storage rack 2, and a frame 4. The air outlet is located at one end of the device housing 1. The storage rack 2 is fixed to one side of the device housing 1. The storage rack 2 is provided with multiple ventilation holes 3 that communicate with the air outlet. The storage rack 2 is provided with a placement slot that communicates with the ventilation holes 3 and the air outlet. The frame 4 is inserted into the placement slot. A first dustproof plate 5 is fixedly installed on the frame 4.
[0030] To facilitate the disassembly and cleaning of the fan blade 12, the present invention is improved by providing a rotating shaft 11 at the output end of the micro motor 10, and fixing the fan blade 12 to one end of the rotating shaft 11 with screws.
[0031] Device assembly and initialization:
[0032] Install the second dustproof plate 15 inside the device housing 1 to complete the construction of the basic dustproof structure.
[0033] Air intake assembly: Insert the cylindrical tube 8, which integrates the first annular cover plate 9 and the annular limiting frame 16, into the empty slot 7 at one end of the device housing 1, and fix the position by threaded connection between the first annular cover plate 9 and the annular frame 6.
[0034] The micro motor 10 is fixed inside the cylindrical tube 8, and the fan blade 12 is installed on the shaft 11 at its output end by screws; the second annular cover plate 14 with the second dustproof plate 15 is fastened on the annular limit frame 16, and the threads are tightened to complete the fixation.
[0035] Exhaust assembly assembly: Insert the frame 4 with the first dustproof plate 5 into the placement slot of the storage rack 2 (the storage rack 2 is fixed to the other end of the device housing 1, and its ventilation holes 3 are connected to the air outlet of the device housing 1). The anti-slip strips around the frame 4 ensure a stable installation.
[0036] Ventilation and heat dissipation operation:
[0037] Start the micro motor 10 to drive the fan blade 12 to rotate at high speed, and draw in cold air from the outside through the ventilation area of the second annular cover plate 14, and send it into the device housing 1 through the cylindrical tube 8.
[0038] Cold air forms convection inside the casing, absorbs the heat generated by the circuit operation, and carries the heat into the storage rack 2 through the air outlet, and is discharged from the first dustproof plate 5 of the frame 4 through the ventilation hole 3, completing the heat dissipation cycle.
[0039] Maintenance and cleaning procedures:
[0040] Clean the second dust cover 15: Loosen the second annular cover 14 (using its anti-slip texture for easy operation), remove it, and then directly clean the dust from the second dust cover 15.
[0041] Inspect and clean the air intake assembly: Loosen the first annular cover 9 to remove the cylindrical tube 8, and the micro motor 10 can be inspected; remove the screws on the fan blade 12 and remove the fan blade 12 to clean the surface dust.
[0042] Clean the first dustproof plate 5: directly pull out the frame 4 (the anti-slip strip makes it easy to grip and apply force), clean the first dustproof plate 5, and then reinsert it into the placement slot.
[0043] The cylindrical tube 8, the first annular cover plate 9, and the annular limiting frame 16 are an integrated structure.
[0044] The second annular cover plate 14, the first annular cover plate 9, the fan blade 12 and the frame 4 can all be disassembled independently, which facilitates quick cleaning of the dustproof plate and the fan blade 12, or maintenance of the micro motor 10, reducing the difficulty and frequency of maintenance.
[0045] The first annular cover plate 9 and the second annular cover plate 14 are provided with anti-slip textures on their periphery, and the frame 4 is provided with anti-slip strips on its periphery.
[0046] The threaded connection (first annular cover plate 9 and annular frame 6, second annular cover plate 14 and annular limit frame 16) ensures that the air intake component is installed firmly, and the anti-slip strip of frame 4 and the storage rack 2 work together to improve the stability of the exhaust component and prevent loosening due to vibration during operation.
[0047] The anti-slip texture of the first annular cover plate 9 and the second annular cover plate 14, as well as the anti-slip strip design of the frame 4, makes assembly and disassembly operations easier and improves user convenience.
[0048] The cylindrical tube 8, the second annular cover plate 14, the storage rack 2, and the frame 4 are all made of plastic.
[0049] The cylindrical tube 8, the second annular cover plate 14, the storage rack 2 and the frame 4 are all made of plastic, which reduces the overall weight while ensuring structural strength, making them suitable for various installation scenarios, and their aging resistance meets the needs of long-term use.
