Description

Technical Field

[0001] This utility model relates to the field of network communication equipment protection technology, and in particular to the dustproof structure of intelligent gateways. Background Technology

[0002] As a core node of the Internet of Things, smart gateways are widely used in industrial control, smart homes, smart cities and other fields, and often need to operate stably for a long time in various complex environments.

[0003] In particular, the air in textile workshops, furniture processing plants, ventilation ducts of old buildings, and bedrooms is rich in lightweight, fibrous pollutants such as cotton fibers, short synthetic fibers, and animal hair. These pollutants are lightweight, easily float, and easily entangle, posing a serious threat to the stable operation of smart gateways.

[0004] Currently, dust prevention for smart gateways mainly involves installing metal mesh or non-woven fabric filters at the air inlet of the device. This method is simple in structure, but for fibrous materials such as cotton fibers, the fibers will quickly adhere to and block the filter holes, causing the ventilation resistance to increase exponentially and the heat dissipation efficiency to deteriorate sharply. Frequent shutdowns for cleaning or replacement are required, which seriously affects the continuous operation of the equipment.

[0005] However, there is an urgent need in the existing technology for a smart gateway dustproof technology solution that can avoid clogging. Utility Model Content

[0006] In view of the technical problems existing in the prior art, the present invention aims to provide a dustproof structure for smart gateways to solve the problem that the existing dustproof structures for smart gateways are prone to clogging in environments with fibrous or other fibrous pollution, which leads to increased wind resistance.

[0007] According to one aspect of the present invention, a dustproof structure for a smart gateway is provided, including a smart gateway body; a dustproof air inlet component, the dustproof air inlet component including a circular air shell, a vortex plate and an air duct, wherein the vortex plate is provided in the inner cavity of the circular air shell to form an air inlet duct that spirals towards the center.

[0008] One end of the duct is connected to the inner cavity of the smart gateway body, and the other end of the duct is connected to the circular air shell, which is used to guide airflow into the interior of the gateway;

[0009] An air inlet pipe is also fixedly connected to the side wall of the circular fan casing, which is used to tangentially introduce dusty air from outside into the inner cavity of the circular fan casing.

[0010] Furthermore, the air duct is located at the center of the circular air casing.

[0011] Furthermore, the axis of the air inlet duct is tangent to the inner wall of the circular air casing.

[0012] Furthermore, a negative pressure fan is fixedly installed inside the duct.

[0013] Furthermore, one or more interception sections are fixedly installed on one side wall of the vortex plate.

[0014] Furthermore, the interception part is an arc plate, and multiple through slots are opened on the arc plate to form a comb-like or grid-like structure.

[0015] Furthermore, a circular sealing bottom cover is detachably connected to the bottom of the circular wind casing, and a vortex plate is fixedly mounted on the circular sealing bottom cover.

[0016] Furthermore, the circular fan casing and the circular sealing bottom cover are detachably fixed together by a positioning and fixing part, which includes a positioning guide rod and a fixing seat. At least two connecting legs are fixedly installed on the side wall of the circular sealing bottom cover, and the positioning guide rod is fixedly connected to the connecting legs. The side wall of the circular fan casing is fixed with a fixing seat matching the number of positioning guide rods, and the fixing seat has a through hole that cooperates with the positioning guide rod.

[0017] Furthermore, a positioning slot is provided on the side wall of the positioning guide rod, and an inner cavity is provided inside the fixing seat. A positioning slider is slidably connected in the inner cavity of the fixing seat. A tenon is fixedly connected to one side of the positioning slider, and the tenon extends into the positioning slot. A spring is fixedly connected to the other side of the positioning slider.

[0018] Furthermore, the outer wall of the fixed base is provided with a sliding groove, and a paddle is slidably connected in the sliding groove of the fixed base. The paddle is fixedly connected to the positioning slider.

[0019] According to this utility model, the dustproof air inlet component pre-treats the air before it enters the gateway's heat dissipation duct. This allows dust particles and fibrous fibers with a density greater than air to be thrown towards the inner wall of the circular air casing under centrifugal force, thereby achieving dust-air separation. This significantly reduces the amount of dust and fiber that directly enters the gateway, effectively protecting internal electronic components and extending the maintenance cycle of the core filter. It is particularly suitable for use in application scenarios with a large amount of textile fibers and lint. Attached Figure Description

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the following will describe it clearly and completely with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are merely exemplary, and this utility model is not limited to the specific embodiments described.

[0028] Please see Figure 1-6 The dustproof structure of the smart gateway includes a smart gateway body 1 and a dustproof air inlet component 5. The dustproof air inlet component 5 includes a circular air shell 501, a vortex plate 504, and an air duct 503. The vortex plate 504 is provided in the inner cavity of the circular air shell 501 to form an air inlet duct that spirals towards the center. One end of the air duct 503 is connected to the inner cavity of the smart gateway body 1, and the other end of the air duct 503 is connected to the circular air shell 501. It is used to introduce pre-treated clean airflow into the interior of the gateway and at the same time provide the core negative pressure suction force for the cyclone in the circular air shell 501. An air inlet pipe 4 is also fixedly connected to the side wall of the circular air shell 501 to introduce external dusty air, especially air rich in light flocculent pollutants such as cotton fibers, tangentially into the inner cavity of the circular air shell 501.

[0029] By pre-treating the air with a forced vortex before it enters the gateway's heat dissipation duct, dust particles and fibrous fibers with a density greater than air can be thrown towards the inner wall of the circular fan housing 501 under centrifugal force, thereby achieving dust-air separation. This significantly reduces the amount of dust and fiber that directly enters the gateway, effectively protecting internal electronic components and extending the maintenance cycle of the core filter. It is particularly suitable for use in applications with a large amount of textile fibers and lint.

[0030] In a preferred embodiment, see [reference] Figure 3 and Figure 4 The duct 503 is located at the center of the circular air casing 501. The vortex plate 504 maintains a certain gap with the outer wall of the duct 503. The spiral end of the vortex plate 504 is connected to the air inlet of the duct 503, thereby guiding the rotating airflow to converge towards the center and enter the duct 503, so as to ensure that the external air can form a stable rotating airflow along the guide surface of the vortex plate 504 and improve the centrifugal separation effect.

[0031] Furthermore, to enhance the centrifugal separation effect and guide the separated pollutants to settle in the designated area, the air inlet duct 4 is located on the upper side wall of the circular air casing 501, and its axis is tangential to the inner wall of the circular air casing 501. Thus, the tangentially entering high-speed airflow forms a high-speed rotating vortex within the circular air casing 501. Dust particles and fibers are continuously thrown outwards by centrifugal force and impact the casing wall. After losing kinetic energy, they slide down the casing wall under gravity and eventually settle and collect at the bottom of the circular air casing 501, achieving preliminary capture and enrichment of pollutants.

[0032] Furthermore, to actively generate a stable intake airflow, ensure continuous and efficient separation, and overcome the resistance of the entire duct, a negative pressure fan 507 is fixedly installed inside the duct 503. Through this technical solution, the negative pressure fan 507 serves as a power source, forming a stable low-pressure zone in the central area of ​​the circular fan housing 501. This not only continuously draws in external air through the inlet duct 4 but also ensures that the purified air is forced into the gateway, providing effective forced convection cooling for heat-generating components such as the device's chips.

[0033] In a preferred embodiment, see [reference] Figure 4 and Figure 5 One or more intercepting parts 505 are fixedly provided on one side wall of the vortex plate 504. Specifically, the intercepting parts 505 are located on the windward side of the vortex plate 504 near the inner wall of the circular wind shell 501, and are distributed at intervals along the spiral direction of the vortex plate 504. Through this technical solution, when the rotating airflow carries fibers that have not completely settled, especially some extremely thin fibers, close to the vortex plate 504, these intercepting parts 505 can perform secondary interception on the airflow, capturing the fiber clumps, as a supplement and guarantee to centrifugal separation.

[0034] As a further preferred technical solution, see Figure 5 To minimize resistance to the main airflow while efficiently intercepting the airflow and providing attachment points for fiber entanglement, the interception part 505 is an arc plate 5051. Multiple through slots 5052 are formed on the arc plate 5051, creating a comb-like or grid-like structure. Through this technical solution, the through slots 5052 allow most of the airflow to pass through, maintaining the overall stability of the cyclone, while the solid portion of the arc plate 5051 effectively impacts and hooks the fibers. The captured fibers adhere to the surface of the arc plate 5051, achieving the fiber capture function.

[0035] To facilitate the later disassembly and cleaning of dust and fibers deposited on the bottom of the circular fan housing 501 and attached to the vortex plate 504 and the interceptor 505, a circular sealing bottom cover 502 is detachably connected to the bottom of the circular fan housing 501, and the vortex plate 504 is fixedly mounted on the circular sealing bottom cover 502. With this technical solution, when maintenance is required, the user only needs to remove the circular sealing bottom cover 502 to remove the vortex plate 504, the interceptor 505, and all contaminants accumulated on the bottom cover as a single module for cleaning. The maintenance operation is simple and does not require touching the precision components inside the gateway, achieving modularity and convenience in dust removal maintenance.

[0036] Furthermore, in order to ensure that the circular sealing bottom cover 502 and the circular fan housing 501 are quickly and accurately aligned and reliably sealed and locked during each installation, the circular fan housing 501 and the circular sealing bottom cover 502 are detachably fixed together by a positioning and fixing part 506. The positioning and fixing part 506 includes a positioning guide rod 5062 and a fixing seat 5064. At least two connecting legs 5061 are fixedly provided on the side wall of the circular sealing bottom cover 502, and the positioning guide rod 5062 is fixedly connected to the connecting legs 5061. The side wall of the circular fan housing 501 is fixed with a number of fixing seats 5064 matching the number of positioning guide rods 5062. The fixing seat 5064 has through holes 5068 that cooperate with the positioning guide rods 5062. This technical solution enables rapid installation. When installation is required, the top of the positioning guide rod 5062 on the circular sealing bottom cover 502 can be aligned with the through hole 5068 on the fixing seat 5064 and inserted. The position is corrected by the guiding action of the guide rod. When disassembly is required, the reverse operation can be performed, which can improve the efficiency of disassembly and assembly, while ensuring the accuracy of repeated installation of the structure.

[0037] Furthermore, see Figure 6The positioning guide rod 5062 has a positioning slot 5063 on its side wall. The fixing seat 5064 has an internal cavity, and a positioning slider 5065 is slidably connected in the cavity of the fixing seat 5064. A latch 5066 is fixedly connected to one side of the positioning slider 5065, and the latch 5066 extends into the positioning slot 5063. A spring 5069 is fixedly connected to the other side of the positioning slider 5065. During installation, when the positioning guide rod 5062 is inserted to the predetermined depth, the latch 5066 automatically engages with the positioning slot 5063 under the elastic force of the spring 5069, making a clear "click" sound and providing tactile feedback, indicating that the installation is in place and locked, preventing the bottom cover from accidentally falling off. The spring 5069 provides a continuous locking force to ensure stability in a vibration environment.

[0038] Preferably, one side of the latch 5066 is curved, and the top of the positioning guide rod 5062 is rounded. With this technical solution, when the positioning guide rod 5062 is inserted, even with slight misalignment, the rounded top of the guide rod interacts with the curved surface of the latch 5066, smoothly pushing the latch 5066 open. This makes the installation process smooth, eliminating the need for precise alignment and facilitating user assembly, thus achieving a user-friendly human-machine interface. For disassembly, simply overcome the elastic force of the spring 5069 to pull the lever 5067, causing the latch 5066 to disengage from the slot.

[0039] To facilitate easy disengagement of the locking latch 5066 during disassembly, the outer wall of the mounting base 5064 is provided with a sliding groove. A lever 5067 is slidably connected within the sliding groove of the mounting base 5064, and the lever 5067 is fixedly connected to the positioning slider 5065. With this technical solution, the user only needs to flick the exposed lever 5067 with their finger to compress the spring 5069 of the internal positioning slider 5065 and latch 5066, causing the latch 5066 to disengage from the positioning slot 5063, thereby easily unlocking and allowing the positioning guide rod 5062 to be pulled out.

[0040] In a preferred embodiment, to enable stable and flexible installation of the smart gateway body 1 and its dustproof air intake component 5 in various industrial environments, a support base 2 and a mounting plate 3 are also included, such as... Figure 1 and Figure 2 As shown, the support base 2 is located below the main body 1 of the smart gateway, and mounting plates 3 are fixed on both sides of the support base 2. The mounting plates 3 are used to fix the device to the wall, column or equipment rail.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
