Description

Technical Field

[0001] This utility model relates to the field of computer chassis technology, specifically a novel double-layer fine filter dustproof mesh for computer chassis. Background Technology

[0002] In the digital age, computers have become indispensable tools for work, study, and entertainment. As the core component supporting computer hardware, the computer case not only provides physical support and protection for various hardware components but also undertakes important functions such as electromagnetic shielding and heat dissipation. Among these, heat dissipation is crucial for ensuring the stable operation of computer hardware and extending its lifespan. However, during operation, the electronic components inside the computer case generate a significant amount of heat, requiring air exchange through ventilation vents for cooling. But the presence of these vents also allows dust to easily enter the case, causing various damages to the computer hardware.

[0003] Dust entering the computer case adheres to the hardware surfaces, especially the heatsink fins and fan blades. Over time, this dust accumulates, forming a heat-insulating layer that severely hinders heat dissipation. This causes the internal temperature of the case to rise, and the high-temperature environment accelerates the aging of hardware, reducing its performance and stability. For example, core hardware such as the CPU and GPU may experience frequency throttling when operating at high temperatures, resulting in slower computer performance and reduced efficiency. Prolonged exposure to high temperatures can also lead to hardware failures, such as power supply damage and hard drive data loss, causing unnecessary losses for users. Therefore, taking effective dust prevention measures is crucial for ensuring the normal operation of the computer case and the long-term stable operation of the hardware. To address this problem, the inventors have proposed a novel double-layer precision dust filter for computer cases. Utility Model Content

[0018] 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.

[0019] like Figure 1-4 As shown, this utility model discloses a novel double-layer fine-filter dustproof mesh 23 for a computer chassis, including a chassis assembly, a power supply assembly, and a dustproof assembly. The power supply assembly is located on the inner wall of the chassis assembly to facilitate power supply to the chassis. The dustproof assembly is located on the inner wall of the chassis assembly to facilitate dust protection of the chassis. The dustproof assembly includes a dustproof fixing block 22, a double-layer fine-filter dustproof mesh 23, and a dustproof bracket 24. The dustproof fixing block 22 is located at one end of the chassis assembly, the dustproof bracket 24 is located on the inner wall of the dustproof fixing block 22, the double-layer fine-filter dustproof mesh 23 is located on the inner wall of the dustproof bracket 24, and also includes a dustproof mesh body 21, which is located on the inner wall of the chassis assembly.

[0020] Specifically, the core of the dustproof component is the double-layer fine filter dustproof mesh 23, which achieves efficient dust interception through the synergistic effect of the two filtration structures:

[0021] Primary filter layer (outer layer): When external cold air enters the chassis, it first passes through the outer layer of the double-layer fine filter dustproof mesh 23, which is fixed by the dustproof bracket 24. This layer uses a primary filter material with large pores and high air permeability (such as a metal mesh or coarse fiber filter), which mainly intercepts larger dust particles (such as hair, fiber debris, etc.) to prevent them from entering the chassis.

[0022] High-efficiency fine filter layer (inner layer): Fine dust particles (such as PM2.5 particles and dust) that are not intercepted by the outer layer will enter the inner layer. The inner layer uses fine filter materials with small pore size and high density (such as microfiber filters or electrostatic adsorption filters), which further filter out fine particles through physical blocking or electrostatic adsorption, ensuring the cleanliness of the air entering the chassis.

[0023] Dust trapped by the double-layer dust filter adheres to the filter surface, gradually forming a dust layer. Due to the inclined or wavy structure of the dust filter (concealed in the fixing method of the dust filter bracket 24), some dust will naturally slide down to the dust collection area at the bottom of the dust filter fixing block 22 under gravity, reducing the risk of filter clogging. Users can maintain dust-proof efficiency by periodically disassembling the dust filter components (the dust filter fixing block 22 and the dust filter bracket 24 are detachable) to clean the dust collection area or replace the filter.

[0024] In addition to the double-layer fine filter dustproof mesh 23, the inner wall of the chassis assembly is also equipped with a dustproof mesh body 21 (such as the auxiliary filter layer inside the side panel 17 or the rear cover 13), serving as a second dustproof barrier. When a small amount of dust breaks through the double-layer fine filter dustproof mesh 23, the dustproof mesh body 21 can further intercept the residual dust through its dense structure (such as honeycomb pores and fine mesh), forming a multi-level protection system of "double-layer main filter + auxiliary body", minimizing the amount of dust entering the chassis.

[0025] The power supply assembly includes a power supply box 31, which is located on the inner wall of the chassis assembly for easy connection to an external power supply, and a power button 32, which is located at one end of the chassis assembly.

[0026] Specifically, the power button 32 is connected to the power supply main body (not shown) control circuit of the power box 31 through internal contacts. When the user presses the button, the contacts close to trigger the power box 31 to start and begin supplying power; pressing it again will open the contacts, the power box 31 will stop outputting power, and the whole machine will be powered off.

[0027] The chassis assembly includes a top cover 11, a front panel 12, and feet 15. The top cover 11 is located on the upper surface of the front panel 12, the front panel 12 is located on the upper surface of the feet 15, a dustproof fixing block 22 is located at one end of the front panel 12, a dustproof mesh body 21 is located on the inner side wall of the front panel 12, a rear cover 13 corresponding to the front panel 12 is located at one end of the top cover 11, a graphics card placement plate 14 for placing the graphics card is located on the inner side wall of the rear cover 13, a bottom plate 18 is located at one end of the rear cover 13, the bottom plate 18 is located on the upper surface of the feet 15, a power supply box 31 is located on the inner side wall of the rear cover 13, a side plate 17 is located on one side of the top cover 11, a lower edge 16 is located on one side of the side plate 17, a power button 32 is located at one end of the lower edge 16, and a motherboard 1 is located on the inner side wall of the side plate 17.

[0028] Specifically, components such as the top cover 11, front panel 12, and side panel 17 form a closed space through rigid connections (such as clips and screws), providing physical support for hardware such as the CPU, GPU, motherboard, and hard drive, and preventing damage caused by external impacts. The feet 15 are designed to raise the bottom of the chassis, reducing direct contact with the ground and decreasing the possibility of dust entering from the bottom. At the same time, the shock-absorbing design buffers vibrations during operation, protecting delicate hardware.

[0029] Featuring a dual-layer fine-filter dust filter design, the synergistic effect of the two filtration layers allows for more precise interception of airborne dust particles (such as fibers and dust), with a significant improvement in filtration efficiency, especially for fine particles. Compared to traditional single-layer dust filters, the dual-layer structure forms a denser filtration barrier, effectively reducing the probability of dust entering the chassis through ventilation openings and mitigating the risk of dust accumulation on hardware at the source.
