[0048] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0049] Firstly, such as Figure 1-3 As shown, this application proposes an air intake structure, including a first structural member 10, having a target side 11, a receiving portion formed on the surface of the target side 11, and a first air intake area 12 provided in the receiving portion;

[0050] The second structural member 20 is disposed in the receiving part to block the first air inlet area 12, and a gap is left between the outer peripheral side of the second structural member 20 and the receiving part to form the second air inlet area 21.

[0051] The second air intake area 21 is connected to the first air intake area 12.

[0052] Understandably, in order to solve the problem of dust entering due to traditional open air inlets, a two-stage air intake area is formed by setting up a first structural component 10 and a second structural component 20. This allows for air circulation while intercepting or filtering dust, thereby improving the reliability of the equipment and the user experience.

[0053] The target side 11 on the first structural member 10 can be the side of the structural member used to arrange the air intake structure.

[0054] The receiving part may have a groove 221 or cavity formed on the surface of the target side 11 for mounting the second structural member 20.

[0055] The first air intake area 12 is located inside the housing and is the channel or through-hole 121 through which air finally enters the equipment.

[0056] The second structural member 20 is disposed within the receiving portion of the first structural member 10 and is capable of shielding the first air intake area 12.

[0057] The outer edge of the second structural member 20 may have a gap with the receiving part to form a second air inlet area 21. The second air inlet area 21 may be a channel or through hole 121 structure that communicates with the first air inlet area 12.

[0058] The airflow path is as follows: external air passes through the second air intake area 21, that is, the gap between the first structural component 10 and the second structural component 20, and enters the other side opposite to the target layer through the first air intake area 12 set on the target side 11 of the first structural component 10, and finally enters the equipment for heat dissipation.

[0059] The air intake structure achieves air guidance and dust interception through a two-stage air intake area. The first stage of dust interception works as follows: air first enters the second air intake area 21. The second air intake area 21, through narrowing or structural changes, increases the airflow velocity, causing some large dust particles to be intercepted by impacting the surface of the second structural component 20 due to inertia. The second stage of dust interception then allows the pre-filtered air to enter the first air intake area 12. This area can be further equipped with filters, baffles, or flow channels to improve filtration efficiency and optimize airflow distribution.

[0060] The dual-stage air intake structure, formed by the first air intake area 12 and the second air intake area 21, effectively reduces the possibility of dust directly entering the equipment. Furthermore, the second structural component 20 can be detachable, facilitating regular cleaning or replacement. This air intake structure can be applied to the housings of intelligent devices, such as routers, switches, docking stations, and industrial control boxes—equipment requiring long-term operation.

[0061] It can also be applied to outdoor electronic devices, such as surveillance cameras, outdoor displays, and base station equipment in dusty environments. It can also be used on the outer casings of household appliances, such as air conditioners, projectors, and audio equipment, to improve dustproof performance.

[0062] like Figure 2 and Figure 4 As shown, in some embodiments, a frame 40 is included, which is disposed on the surface of the target side 11 to form a receiving portion;

[0063] The second structural member 20 includes a first side 22 facing the target side 11 and a second side 23 facing away from the target side 11;

[0064] The projection area of ​​the second structural member 20 along the first direction can cover the first air intake area 12, thereby shielding the first air intake area 12.

[0065] The first direction is the direction from the second side 23 of the second structural member 20 to the first side 22.

[0066] Understandably, the frame 40 is set on the surface of the target side 11 of the first structural member 10. The frame 40 can be rectangular, circular, or other frame structures, used to enclose a recessed area together with the surface of the target side 11 to form a receiving portion. After the second structural member 20 is placed in the receiving portion, it can be hidden within the frame 40 or the surface of the second side 23 can meet the condition of being coplanar with the frame 40, so that the product structure is compact, aesthetically pleasing, and has strong overall integrity.

[0067] The second air intake area 21 is formed by the gap between the inner side of the frame 40 and the outer side of the second structural member 20.

[0068] The second structural member 20 includes a first side 22 close to the target side 11, which may face the surface of the first structural member 10, and a second side 23 away from the target side 11, which is an outward-facing side that directly faces the outside air.

[0069] The projection area of ​​the second structural member 20 along the direction from the second side 23 to the first side 22 completely covers the first air intake area 12. This means that, from the outside, the first air intake area 12 is not directly visible due to the obstruction of the second structural member 20; air must enter the receiving part through the gap between the second structural member 20 and the frame 40. This structure effectively prevents dust and foreign objects from directly entering the equipment, thus improving the protection level.

[0070] By ensuring that the projected area of ​​the second structural component 20 is greater than or equal to the area of ​​the first air intake area 12, it is ensured that the first air intake area 12 is not exposed to the outside, preventing dust from being directly blown into the equipment. The second structural component 20 can be a cover plate with one side surface area greater than or equal to the surface area of ​​the other side.

[0071] In some embodiments, such as Figure 3 and Figure 5 As shown, the first side 22 of the second structural member 20 is provided with a groove 221, which is corresponding to the first air inlet area 12. Both ends of the groove 221 extend toward the frame 40 to connect with the second air inlet area 21, so that the groove 221 and the surface of the target side 11 enclose the target channel 30.

[0072] Understandably, the groove 221 is located on the first side 22 of the second structural member 20, that is, the surface facing the target side 11. The groove 221 can be a partially sunken area. The groove 221 is a long strip groove 221 structure, with both ends extending towards the frame 40. It can extend vertically or obliquely, which is not limited here. It is to connect the second air inlet area 21, that is, the gap between the outer periphery of the second structural member 20 and the receiving part, so that the external air can pass through the second air inlet area 21, the groove 221, and enter the target channel 30 in sequence, and finally flow into the first air inlet area 12.

[0073] The groove 221 is correspondingly provided with the first air inlet area 12 to form a guide path from the outside air to the inside of the equipment, so as to guide the air into the target channel 30, and then from the target channel 30 through the first area into the inside of the equipment housing.

[0074] The target channel 30 is formed by a groove 221 on the first side 22 of the second structural member 20, the target side 11 surface of the first structural member 10, and a portion of the edge structure of the frame 40. This target channel 30 is the main path for air to enter the first air intake area 12 from the second air intake area 21, making it easier for dust in the air to settle and preventing it from directly entering the device. Furthermore, the groove 221 is integrated into the interior of the second structural member 20, without occupying additional space, making it suitable for miniaturized electronic devices. The second structural member 20 can be detachably installed, facilitating regular cleaning of the groove 221 and the target channel 30. Furthermore, an electrostatic adsorption layer can be provided in the groove 221 to more effectively prevent dust from entering the device. Even further, antistatic materials or a hydrophobic coating can be used in the groove 221 to reduce dust adhesion, allowing dust to be discharged from the target channel 30 with the airflow.

[0075] In some embodiments, such as Figure 3 As shown, the bottom inner wall of the target channel 30 is provided with an inclined dust guiding slope 50. The end of the dust guiding slope 50 extends to the outside of the frame 40 and forms a dust discharge port 60 that communicates with the target channel 30. The dust discharge port 60 faces the second direction. The second direction satisfies the opposite condition to the first direction.

[0076] Understandably, by setting an inclined dust-guiding slope 50 at the bottom of the target channel 30, the dust prevention and dust removal capabilities of the air intake structure are further enhanced.

[0077] The dust-guiding slope 50 is set on the bottom inner wall of the target channel 30. It can be unidirectionally inclined and its surface can be smoothed or have a dust-repellent coating. It can guide the dust settling in the air to move downward along the slope and prevent dust from accumulating inside the target channel 30.

[0078] The dust outlet 60 is located at the end of the dust guiding slope 50, extending to the outside of the frame 40 and communicating with the target channel 30. The dust outlet 60 faces a second direction, which is the direction from the first side 22 to the second side 23 of the second structural member 20, that is, the direction from the inside to the outside.

[0079] Through the above structure, dust is discharged outward through the dust outlet 60, preventing it from entering the equipment. Automatic dust removal is achieved by utilizing airflow inertia and gravity.

[0080] In some embodiments, the first air intake area 12 is provided with a dustproof net, which is disposed on the side of the first structural member 10 facing the second structural member 20 or on the side away from the second structural member 20.

[0081] Understandably, the dust filter is installed in the first air intake area 12 to intercept fine particles.

[0082] One implementation method is to place the dustproof net on the side of the first structural member 10 facing the second structural member 20, that is, the dustproof net is close to the outlet of the target channel 30. The air passes through the dustproof net before entering the first air intake area 12, intercepting dust earlier and preventing it from entering the equipment. Dust is less likely to accumulate in the first air intake area 12.

[0083] Another implementation is that the dustproof net is located on the side of the air outlet of the first air inlet area 12. Air first enters the first air inlet area 12 and then passes through the dustproof net, which can serve as the last barrier to prevent extremely fine particles from entering the equipment.

[0084] In some embodiments, such as Figure 6 As shown, the first air inlet area 12 includes a plurality of through holes 121 arranged at intervals, and the groove 221 is correspondingly provided with the through holes 121 so that the first air inlet area 12 is connected to the target channel 30.

[0085] Understandably, the first region includes multiple through holes 121 arranged at intervals. Multiple through holes 121 can be formed on the target side 11 surface of the first structural member 10. These through holes 121 are distributed regularly or asymmetrically, with each through hole 121 serving as an "entry point" for air to enter the device. This increases the total air intake area, improves heat dissipation efficiency, and the distributed air intake helps reduce localized overheating. It is also easy to use with dustproof structures such as filters and grilles.

[0086] The through-hole 121 is correspondingly provided with the groove 221 of the second structural member 20. The groove 221 serves as a guide structure for airflow to enter the through-hole 121 from the target channel 30. This ensures that each through-hole 121 can obtain a stable airflow, avoids airflow short-circuiting or local dead zones, and the size of the groove 221 can be adjusted according to the size of different through-holes 121 to optimize the airflow speed.

[0087] The through hole 121 can be in different shapes such as circular, hexagonal, or honeycomb, and can also be adapted to different wind speed requirements by changing the distribution of hole size.

[0088] In some embodiments, such as Figure 7 As shown, the through hole 121 includes a first opening 1211 disposed on the surface of the target side 11 and a second opening 1212 disposed opposite to the first opening 1211 and away from the surface of the target side 11. The first opening 1211 and the second opening 1212 communicate to form the through hole 121, and a dustproof net is disposed in the second opening 1212.

[0089] The diameter of the first opening 1211 is larger than the diameter of the second opening 1212, so that the transition section after the second opening 1212 connects with the first opening 1211 is inclined at an angle to the target side 11.

[0090] Understandably, the structure of through hole 121 is further refined, and the structure of through hole 121 is in an inclined state.

[0091] The first opening 1211 is located on the surface of the target side 11 and has a large diameter, serving as the inlet for airflow to enter the through hole 121.

[0092] The second opening 1212 is located on the opposite side of the first opening 1211, i.e., in the direction of the inside of the equipment, and has a smaller diameter. It is the outlet for the airflow to flow out of the through hole 121 and into the inside of the equipment.

[0093] The first opening 1211 and the second opening 1212 are connected by an inclined transition section. The transition section can have a "trumpet-shaped contraction" structure. The inclined angle helps the airflow to transition smoothly, and dust settles or returns to the external channel, thereby effectively reducing the probability of particulate matter entering the equipment.

[0094] The dustproof net is installed at the second opening 1212, that is, on the side closer to the inside of the device, as the last filter barrier to prevent fine particles from entering the device. It can be made of filter screen, metal mesh, etc.

[0095] The through-hole 121 features a tapered constriction structure that ensures more stable airflow. A double-layered protection system, utilizing an inclined transition section and a dust filter, effectively reduces dust entry into the equipment. The inclined transition section also facilitates dust sliding off or bouncing back into the external channel. This compact structure is suitable for small electronic devices.

[0096] In some embodiments, the second structural member 20 is detachably connected to or fixedly connected to the first structural member 10.

[0097] Understandably, the second structural component 20 can be easily removed and installed compared to the first structural component 10, and is often used in scenarios requiring regular cleaning, filter replacement, or structural adjustments. The detachable connection can be a magnetic connection, using magnets to attach and secure the second structural component 20, allowing for quick installation and removal, suitable for frequent operations. Alternatively, it can be a plug-in connection, with a socket in the first structural component 10 and a plug in the second structural component 20, enabling quick connection and disassembly, simplifying operations and reducing costs.

[0098] The second structural component 20 and the first structural component 10 can also be permanently fixed together. This fixed connection can be adhesive bonding, which is simple and results in a neat product appearance. Alternatively, they can be injection molded as a single unit, with the first structural component 10 and the second structural component 20 molded in one step, leading to low manufacturing costs and strong overall integrity.

[0099] Secondly, such as Figure 1-3 and Figure 8 As shown, this disclosure proposes a shell, including: a shell body 70 for forming a receiving space;

[0100] First structural member 10 is disposed on the outer surface of shell body 70. First structural member 10 has target side 11. Target side 11 has a receiving portion formed on its surface. The receiving portion is provided with a first air inlet area 12. The first air inlet area 12 is connected to the receiving space.

[0101] The second structural member 20 is disposed in the receiving part to block the first air inlet area 12, and a gap is left between the outer peripheral side of the second structural member 20 and the receiving part to form the second air inlet area 21.

[0102] The second air intake area 21 is connected to the first air intake area 12.

[0103] Understandably, the shell body 70 can serve as the main external structure of the device, with internal storage space for placing electronic components (such as motherboards, power modules, fans, etc.). It can be made of plastic, metal, or composite materials.

[0104] The first structural member 10 can be disposed on the outer surface of the shell body 70, and the target side 11 is the side facing the external environment; the receiving part can be a recessed area on the surface of the target side 11, used to receive the second structural member 20. The first air inlet area 12 is disposed in the receiving part and is composed of multiple through holes 121 and grilles, and is connected to the receiving space inside the shell body 70, serving as the final air inlet.

[0105] The second structural member 20 is embedded / installed in the receiving portion of the first structural member 10 to shield the first air intake area 12 and prevent dust from entering directly. A gap is left between the outer periphery of the second structural member 20 and the receiving portion to form the second air intake area 21. The second structural member 20 and the first structural member 10 can be detachably connected or fixedly connected.

[0106] The external airflow path is as follows: through the gap between the second structural member 20 and the receiving part, i.e. the second air intake area 21, it enters the internal channel of the receiving part, and then enters the receiving space inside the shell body 70 through the first air intake area 12 for heat dissipation.

[0107] Thirdly, such as Figure 1-3 and Figure 8 As shown, this disclosure proposes an electronic device, including: a housing body 70, the housing body 70 having an exhaust vent and forming an accommodating space;

[0108] The carrier is placed in the containment space and is used to hold electronic components, which generate heat when in operation.

[0109] First structural member 10 is disposed on the outer surface of shell body 70. First structural member 10 has target side 11. Target side 11 has a receiving portion formed on its surface. The receiving portion is provided with a first air inlet area 12. The first air inlet area 12 is connected to the receiving space.

[0110] The second structural member 20 is disposed in the receiving part to block the first air inlet area 12, and a gap is left between the outer peripheral side of the second structural member 20 and the receiving part to form the second air inlet area 21.

[0111] The second air intake area 21 is connected to the first air intake area 12. External air from the shell body 70 enters the containment space through the second air intake area 21 and the first air intake area 12 in sequence and is discharged through the exhaust port to reduce the temperature of the electronic components during operation.

[0112] Understandably, the housing 70 has a recessed space for mounting electronic components and an exhaust vent for expelling hot air. The housing provides physical protection against external factors such as impacts and moisture, preventing damage to the internal components. Different materials (such as plastics and metals) can be selected to optimize weight, strength, and heat dissipation performance, depending on requirements.

[0113] The carrier is placed within the housing space to support electronic components. It serves as a support structure between the electronic components and the housing, helping to conduct heat from the electronic components to the housing or heat sink. The carrier can be a PCB board, heat sink bracket, heat-conducting plate, mounting plate, fan bracket, etc.

[0114] The first structural member 10 can be disposed on the outer surface of the shell body 70, and the target side 11 is the side facing the external environment; the receiving part can be a recessed area on the surface of the target side 11 for accommodating the second structural member 20. The first air inlet area 12 is disposed in the receiving part and is composed of multiple through holes 121 and grilles, and is connected to the receiving space inside the shell body 70, serving as the final air inlet to guide external air into the equipment.

[0115] The second structural member 20 is embedded / installed in the receiving portion of the first structural member 10 to shield the first air intake area 12 and prevent dust from entering directly. A gap is left between the outer periphery of the second structural member 20 and the receiving portion to form the second air intake area 21. The second structural member 20 and the first structural member 10 can be detachably connected or fixedly connected.

[0116] The external airflow path is as follows: through the gap between the second structural member 20 and the receiving part, i.e. the second air intake area 21, it enters the internal channel of the receiving part, and then enters the receiving space inside the shell body 70 through the first air intake area 12 (e.g., through hole 121, grille, etc.). The heat is carried away by the electronic components on the carrier and discharged from the exhaust port to achieve the heat dissipation effect inside the electronic equipment.
