Description

Technical Field

[0001] This disclosure relates to the field of dustproof device technology, and in particular to a dustproof device and a dustproof enclosure. Background Technology

[0002] The computer case is a crucial component of computer hardware, primarily used to install and protect various core hardware components inside, such as the motherboard, processor (CPU), memory, graphics card, and power supply. The case not only provides physical support but also ensures effective heat dissipation for the hardware components through a well-planned layout, preventing performance degradation or hardware damage caused by overheating. While the perforated design of the case improves heat dissipation, it also introduces a common problem—dust ingress. Dust particles in the air easily enter the case through these perforations, gradually accumulating on the hardware surfaces, especially in the gaps between fan blades, heatsinks, and the motherboard. Prolonged dust accumulation not only obstructs airflow and reduces heat dissipation but can also lead to short circuits or hardware damage, affecting the normal operation of the computer.

[0003] While existing computer cases have protective devices such as filters in their open areas to filter dust particles from the air, these filters tend to accumulate dust after prolonged use. They are difficult to clean quickly and usually require disassembling the case, which is not only troublesome and inefficient but also makes it difficult to quickly restore the filtering effect of the filters.

[0004] In view of this, there is an urgent need in the market for a new type of dustproof device to solve the problem that cleaning and dust removal of existing chassis filter protection devices is troublesome after long-term use and it is difficult to quickly restore the filtration effect.

[0048] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0049] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0050] Combination Figure 1 and Figure 2As shown, this embodiment of the present disclosure provides a dustproof device, which includes a sealing plate 1, a filter assembly 2, and a dust removal component 3; the sealing plate 1 has a through-hole portion 11; the filter assembly 2 is disposed on the sealing plate 1 and can correspondingly block the through-hole portion 11; the dust removal component 3 is disposed on the sealing plate 1 and can remove dust from the filter assembly 2; wherein, the filter assembly 2 includes a filter element 21 and an adjusting component 22; the adjusting component 22 is used to switch and adjust the position of the filter element 21 in the sealing plate 1, so that the filter element 21 is correspondingly disposed with the through-hole portion 11 or the dust removal component 3; when the filter element 21 moves relative to the dust removal component 3, the dust removal component 3 can correspondingly scrape the dust accumulated on the surface of the filter element 21.

[0051] The dustproof device provided in this embodiment includes: a sealing plate 1 made of metal sheet with a through rectangular hollow section 11 for airflow and air exchange between the inside and outside of the casing; a filter assembly 2 consisting of a filter element 21 and an adjusting element 22, wherein the filter element 21 is a detachable mesh filter made of corrosion-resistant woven metal wire to intercept dust particles; the adjusting element 22 is a manual knob mechanism connected to the filter element 21 for controlling the position switching of the filter element 21; and a dust removal component 3 fixed to the inside of the sealing plate 1 with a serrated protrusion on its surface for scraping when in contact with the surface of the filter element 21.

[0052] The dustproof device provided in this embodiment can specifically include a dustproof mode and a dust removal mode. In the dustproof mode, the filter element 21 is moved to the position covering the perforated portion 11 via the adjusting component 22. At this time, external air enters the casing through the filter element 21, and dust is intercepted by the filter screen, thus achieving the dustproof function. In the dust removal mode, when there is a large amount of dust on the surface of the filter element 21, the adjusting component 22 is operated to switch the filter element 21 to the position corresponding to the dust removal component 3. Then, the filter element 21 is manually or automatically driven to move laterally along the surface of the dust removal component 3, and the serrated structure of the elastic rubber scraper scrapes away the accumulated dust on the filter screen surface, thus completing the cleaning process.

[0053] The dustproof device provided in this embodiment can flexibly switch the filter element 21 between dustproof and dust removal modes through the adjustment component 22, and can be cleaned without disassembling the filter screen, which significantly improves maintenance efficiency; moreover, the motion coordination design between the dust removal component 3 and the filter element 21 can effectively remove stubborn dust through scraping action, extending the service life of the filter screen; in addition, the overall structure of the dustproof device is compact and can be directly integrated into the chassis panel, saving installation space.

[0054] In one embodiment, the filter element 21 includes a first filter section 211 and a second filter section 212, which are connected by a connector 213. The first filter section 211 and the second filter section 212 can be respectively disposed with the hollow section 11 and the dust removal component 3. The adjusting member 22 is connected to the connector 213 and can drive the connector 213 to rotate around the adjusting member 22 to switch and adjust the relative positions of the first filter section 211 and the second filter section 212.

[0055] Specifically, in combination Figure 2 and Figure 4 In further detail, the filter element 21 is configured to include a first filter section 211 and a second filter section 212. Both the first filter section 211 and the second filter section 212 can be configured as circular or rectangular metal filter screens, and they can also have different mesh sizes. For example, the first filter section 211 can be a coarse filter screen, and the second filter section 212 can be a fine filter screen, to adapt to different filtration needs. The first filter section 211 and the second filter section 212 are fixedly connected by a connector 213. The connector 213 can be configured as a metal frame, which is fixed to the edges of the first filter section 211 and the second filter section 212 by welding or bonding, so that the two can form a symmetrical distributed structure.

[0056] When the filter element 21 is in operation, the first filter section 211 can be placed over the perforated portion 11 of the sealing plate 1 to filter the airflow entering the chassis, and the second filter section 212 can be positioned above the dust collector 3. When the dust accumulation on the surface of the first filter section 211 reaches a threshold, the adjusting component 22 can rotate 180° to move the second filter section 212 to the position covering the perforated portion 11, continuing to provide dust prevention. At the same time, the first filter section 211 moves to the position corresponding to the dust collector 3, and during the movement, it contacts the brush head of the dust collector 3 to scrape off the accumulated dust in the first filter section 211, achieving a seamless switch between dust prevention and cleaning.

[0057] The specific arrangement of the filter element 21 can maintain continuous dust prevention during cleaning by alternating the operation of the dual filter sections, preventing dust from entering the inside of the chassis; and the differentiated filtration design of the first filter section 211 and the second filter section 212, such as the combination of coarse and fine filtration, can improve filtration efficiency and extend the service life of the filter screen; the first filter section 211, the second filter section 212 and the connecting part 213 can adopt an integrated structure and be linked with the adjustment part 22, simplifying the operation logic and reducing the complexity of maintenance.

[0058] Of course, the shape of the connecting member 213 is not limited to a ring frame. For example, a U-shaped or rod-shaped structure can also be used to achieve synchronous movement of the two filter parts. The rotation angle of the adjusting member 22 can be adjusted according to actual needs, such as 90° or 120°, to adapt to the layout differences of the sealing plate member 1 or the dust removal member 3.

[0059] In one embodiment, the adjusting member 22 includes an adjusting knob 221 and a threading post 222; one end of the threading post 222 is connected to the connecting member 213, and the other end is connected to the adjusting knob 221; the threading post 222 is inserted into the sealing plate member 1, and the adjusting knob 221 is located on the side of the sealing plate member 1 that is away from the filter member 21.

[0060] Specifically, in combination Figure 4 In further detail, the adjusting component 22 is specifically configured to include an adjusting knob 221 and a mounting post 222. One end of the mounting post 222 is connected to the connecting component 213, and the other end is connected to the adjusting knob 221. In this way, when the adjusting knob 221 is turned manually or automatically, the mounting post 222 can correspondingly drive the connecting component 213 to rotate, thereby realizing the switching of the position of the filter element 21.

[0061] Furthermore, the inserting post 222 can be inserted into the pre-drilled hole in the sealing plate 1, and a rotational seal with the sealing plate 1 is achieved through a bearing, so that the adjusting knob 221 is located on the outside of the sealing plate 1, i.e., outside the chassis, while the connecting piece 213 and the filter piece 21 are located on the inside of the sealing plate 1, i.e., inside the chassis. In this way, when the user rotates the adjusting knob 221 from the outside, the inserting post 222 drives the connecting piece 213 to rotate around the axis, thereby synchronously switching the positions of the first filter part 211 and the second filter part 212.

[0062] The aforementioned adjusting component 22 can be operated externally via the sealing engagement between the mounting post 222 and the sealing plate 1, allowing for the switching of the filter section position without disassembling the chassis. This also prevents dust from entering the chassis through the gap between the adjusting component 22 and the sealing plate 1. The separate design of the adjusting knob 221 and the mounting post 222 also facilitates replacement or maintenance.

[0063] In one embodiment, the dust removal component 3 includes a built-in brush body disposed in the sealing plate component 1; and the built-in brush body is distributed in a fan shape in the sealing plate component 1 and has a brush head protruding from the sealing plate component 1; when the first filter part 211 or the second filter part 212 rotates around the adjusting member 22, it can respectively abut against the fan-shaped built-in brush body so that the brush head scrapes the dust accumulated on the surface of the filter component 21.

[0064] Specifically, in combination Figure 3In further detail, the dust removal component 3 can be a built-in brush body located inside the sealing plate 1. Its bristles can be made of materials such as nylon, rubber, plastic, or wool, and the brush body can be fan-shaped, with the brush head protruding 1mm-3mm from the inner surface of the sealing plate 1. Thus, when the first filter section 211 or the second filter section 212 rotates around the adjusting member 22, the surface of the filter section can contact the fan-shaped brush head. The bristles generate scraping force through elastic deformation, thereby removing accumulated dust from the surface of the filter section. For example, during the process of the filter section switching from the perforated section 11 to the dust removal component 3, the arc path of the fan-shaped brush body matches the movement trajectory of the filter section, ensuring that the brush head contacts the entire area of ​​the filter screen.

[0065] The specific arrangement of the dust removal component 3 described above is such that the fan-shaped distributed brush body can cover the maximum sweeping area when the filter moves, avoiding blind spots in cleaning; the scraping action of the elastic bristles can adapt to the uneven structure of the filter screen surface, improving dust removal efficiency while reducing wear on the filter screen.

[0066] In one embodiment, the sealing plate 1 is further provided with a dust collection box 4 located below the dust removal component 3; the dust collection box 4 is used to collect the dust scraped off from the surface of the filter component 21 by the dust removal component 3.

[0067] Specifically, in combination Figure 3 In further detail, the dust collection box 4 can be configured as a drawer-type structure, and can be installed on the inner bottom of the sealing plate 1 via a slide rail or via a locking mechanism, and is located directly below the dust collection component 3.

[0068] When the dust collector 3 scrapes against the filter element 21, the detached dust falls into the dust collection box 4 under gravity. The side wall of the dust collection box 4 can be provided with a transparent observation window, which allows the user to check the amount of dust from outside the chassis and clean it in a timely manner.

[0069] The specific arrangement of the dust collection box 4 mentioned above makes it easy to collect the dust that has been scraped off, preventing the dust from spreading inside the chassis and causing secondary pollution; moreover, the dust collection box 4 can be removed and cleaned separately, which significantly reduces maintenance costs.

[0070] In one embodiment, the dustproof device further includes a dustproof plate 5; the dustproof plate 5 is spaced apart from the sealing plate 1 and covers the dust removal component 3 accordingly; a dust removal space is formed between the dustproof plate 5 and the dust removal component 3 for relative movement of the filter component 21.

[0071] Specifically, in combination Figure 1In further detail, the dust separator 5 can be a transparent acrylic sheet, connected to the edge of the sealing plate 1 by clips, and maintaining a 5-10mm gap between the dust separator 5 and the sealing plate 1, thus forming a dust removal space between the dust separator 5 and the sealing plate 1. When the filter element 21 is switched to the dust removal position, it moves within this dust removal space, and the dust separator 5 confines the dust raised during the dust removal process within the space, preventing it from spreading to other areas of the chassis.

[0072] The specific arrangement of the dustproof plate 5 mentioned above can achieve spatial enclosure of the dust removal process through physical isolation, thereby improving the directionality and safety of cleaning operations; and the use of transparent material makes it easy to observe the dust removal status.

[0073] In one embodiment, the sealing plate 1 is provided with a support strip 12 at one edge of the filter assembly 2; the support strip 12 can be supported and connected to the dustproof plate 5.

[0074] Specifically, in combination Figure 1 In further detail, the sealing plate 1 may have a supporting strip 12 at its edge, such as a rigid plate strip, and may have a corresponding mounting groove that matches the thickness of the dustproof plate 5. Thus, during installation, the edge of the dustproof plate 5 is inserted into the groove of the supporting strip 12, achieving a tight snap-fit.

[0075] The specific arrangement of the aforementioned support strip 12 can provide stable physical support and shock absorption, preventing the dustproof plate 5 from shifting or falling off due to airflow or equipment vibration.

[0076] In one embodiment, the sealing plate 1 has a fastening strip 13 at one edge where the filter assembly 2 is located; the fastening strip 13 is used to fasten the sealing plate 1 to the main body of the chassis.

[0077] Specifically, in combination Figure 1 In further detail, a fastening strip 13 may be provided on the edge of the sealing plate 1. The fastening strip can be a plate-type or L-shaped metal strip. Its horizontal edge is fixed to the mounting holes of the chassis body 7 by screws, and its vertical edge is fitted against the side wall of the sealing plate 1. The length of the fastening strip 13 can cover the entire mounting edge of the sealing plate 1 to ensure the sealing of the connection between the sealing plate 1 and the chassis body 7.

[0078] The specific arrangement of the fastening strip 13 mentioned above can enhance the structural strength of the sealing plate 1 by fixing it with multiple screws, preventing deformation due to long-term use; the metal material provides high rigidity support, while also taking into account electromagnetic shielding requirements.

[0079] In one embodiment, the dustproof device further includes a cooling fan 6; the cooling fan 6 is mounted on one side of the sealing plate 1 via a support member 61; the cooling fan 6 and the hollowed-out portion 11 are arranged at intervals, and a accommodating space for accommodating the filter element 21 is formed between them.

[0080] Specifically, in combination Figure 1 In further detail, the cooling fan 6 can be mounted on the side of the cover plate 1 opposite to the filter 21 via a support 61, such as a metal bracket, and maintain a 20mm-30mm gap from the perforated portion 11 to form an accommodating space. In dustproof mode, the filter 21 is located within this accommodating space. When the cooling fan 6 is running, airflow passes through the filter 21 and the perforated portion 11 into the chassis, achieving forced convection cooling.

[0081] The specific arrangement of the cooling fan 6 and the collaborative design of the cooling fan 6 and the filter 21 ensure dustproof performance while improving heat dissipation efficiency; the housing space avoids interference between the fan blades and the filter 21.

[0082] In addition, this embodiment of the present disclosure also provides a dustproof enclosure, which includes an enclosure body 7 and the aforementioned dustproof device; wherein, the sealing plate 1 is correspondingly sealed in the enclosure body 7, and the filter 21 and the dust removal component 3 are located inside the enclosure body 7, and the adjusting component 22 is located outside the enclosure body 7.

[0083] Specifically, in combination Figure 5 In further detail, the dustproof enclosure includes the enclosure body 7 and the aforementioned dustproof device, which can achieve all the beneficial effects of the aforementioned dustproof device, and will not be elaborated further here.

[0084] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means two or more, unless otherwise explicitly specified.

[0085] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
