Description

Technical Field

[0001] This invention belongs to the field of network switch technology, and in particular relates to a network switch with waterproof function. Background Technology

[0002] A network switch is a core network device used for forwarding electrical or optical signals. It provides a dedicated data transmission path for multiple network nodes (such as computers, servers, cameras, etc.). It operates at the data link layer of the OSI model. By identifying the MAC address in the data packet, it accurately forwards data from the source port to the destination port, avoiding data conflicts in the shared network and greatly improving network bandwidth utilization and transmission efficiency. For example, patent CN210839637U discloses a network switch.

[0003] Currently, network switches are core network devices in internet cafes, small factories, and small and medium-sized companies. Due to cost, space, or professional limitations, these scenarios often lack standardized server rooms and cabinets, resulting in network switches being placed directly on desktops, corners, or even the floor. These rudimentary placement environments have poor protection conditions, especially in terms of waterproofing. In high-humidity environments such as during humid seasons, water droplets can easily form inside the network switch, leading to the following problems:

[0004] First, the water droplets conduct electricity, causing a short circuit in the circuit, burning out the core components and causing the equipment to malfunction.

[0005] Second, moisture containing impurities forms electrolytes, causing corrosion and oxidation of metal pins and interface contacts, leading to poor contact, unstable signals, or functional module failure.

[0006] Third, a humid environment can also breed mold, which damages insulation, blocks heat dissipation, and exacerbates corrosion. This can lead to a sharp drop in network stability, a shortened lifespan, and increased maintenance costs for network switches, thus affecting the stability and effectiveness of network switch use.

[0007] Therefore, we propose a waterproof network switch to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to address the above-mentioned problems by providing a network switch with waterproof functionality.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a network switch with waterproof function, including a switch body, a protective box fixedly connected to the lower surface of the switch body, a vertical partition fixedly connected to the inner wall of the protective box, and a horizontal partition fixedly connected to the outer wall of the vertical partition and the inner wall of the protective box.

[0010] The vertical and horizontal partitions together divide the internal cavity of the protective box into an air intake zone, a cooling zone, and a water storage zone.

[0011] The protective box is fixedly connected to the air intake mechanism on the inner wall of the air intake area;

[0012] The upper surface of the diaphragm is provided with a rectangular through hole, and the wall of the rectangular through hole is fixedly connected with a waterproof mechanism.

[0013] The protective box is fixedly connected to the inner wall of the air intake area by a PLC controller. The protective box is fixedly embedded with a temperature sensor and a humidity sensor on the top outer wall of the air intake area. The lower surface of the switch body is provided with a detection through hole that cooperates with the detection end of the temperature sensor.

[0014] In the aforementioned waterproof network switch, the air intake mechanism includes a miniature air pump. The bottom end of the miniature air pump is fixedly connected to the inner wall of the bottom of the protective box. A threaded cylinder is fixedly connected to the side wall of the protective box in the air intake area. The side end of the threaded cylinder is fixedly connected to the air intake end of the miniature air pump. A filter assembly is threadedly sealed to the inner wall of the threaded cylinder. A bent pipe is fixedly connected to the air outlet end of the miniature air pump. A circular hole is opened at the bottom of the vertical partition, and a U-shaped metal tube is fixedly connected to the wall of the circular hole. The air outlet end of the U-shaped metal tube passes through the upper surface of the horizontal partition and communicates with the cavity of the protective box in the cooling area. The air outlet end of the bent pipe is fixedly connected to the air intake end of the U-shaped metal tube.

[0015] In the aforementioned waterproof network switch, the filter assembly includes a connecting ring that is threadedly sealed to the inner wall of the threaded cylinder side end. A filter screen is fixedly connected to the inner wall of the connecting ring. A U-shaped limiting frame is fixedly connected to the side of the connecting ring away from the filter screen. A sponge filter block is movably connected to both the U-shaped limiting frame and the inner wall of the connecting ring.

[0016] In the aforementioned waterproof network switch, the waterproof mechanism includes a semiconductor cooling chip fixedly connected to a horizontal partition. Multiple first metal mesh sheets are fixedly connected to the cooling side surface of the semiconductor cooling chip. A fixing hole is provided on the upper surface of the horizontal partition, and a discharge check valve is fixedly connected to the wall of the fixing hole. An exhaust pipe is fixedly connected to the side wall of the protective box located in the water storage area. A rectangular hole is provided at the top of the vertical partition, and an L-shaped square tube is fixedly connected to the wall of the rectangular hole. The air outlet end of the L-shaped square tube passes through the top of the protective box and is fixedly connected to the lower surface of the switch body. A breathable support cover is fixedly sleeved on the air inlet end of the L-shaped square tube, and a waterproof and breathable membrane cover is fixedly connected to the inner wall of the breathable support cover.

[0017] In the aforementioned waterproof network switch, a plurality of second metal mesh sheets are fixedly connected to the heat dissipation side surface of the semiconductor cooling chip, and a drain valve is fixedly connected to the bottom outer wall of the protective box located in the water storage area.

[0018] In the aforementioned waterproof network switch, a water pressure sensor is fixedly connected to the inner wall of the bottom of the protective box in the water storage area, and a buzzer alarm is fixedly embedded in the side wall of the protective box in the air intake area.

[0019] In the aforementioned waterproof network switch, anti-slip support blocks are fixedly connected to the four corners of the lower surface of the protective box, and limiting rings that cooperate with the anti-slip support blocks are fixedly connected to the four corners of the upper surface of the switch body.

[0020] In the aforementioned waterproof network switch, the side wall of the switch body is provided with multiple mounting holes, and the wall of the mounting holes is fixedly connected with an exhaust pipe.

[0021] Compared to existing technologies, the advantages of a waterproof network switch are:

[0022] 1. Through its air intake mechanism, waterproof mechanism, and filter components, when the network switch operates in a rudimentary environment, a temperature sensor first monitors the internal temperature of the switch body and converts it into an electrical signal, which is then sent to the PLC controller. If the internal temperature of the switch body exceeds the first temperature threshold preset by the PLC controller, the PLC controller controls a miniature air pump to activate the air intake mechanism. The air intake mechanism injects air into the switch body through a cooling zone and an L-shaped square tube, increasing airflow within the switch body and accelerating heat dissipation. If the temperature sensor detects that the internal temperature of the switch body continues to rise and reaches the second temperature threshold preset by the PLC controller, the PLC controller not only controls the miniature air pump but also controls the semiconductor cooling system. The system operates by cooling the thermoelectric cooler on its cooling side. Then, outside air, supplied through a U-shaped metal tube, is cooled by the thermoelectric cooler and the first metal mesh in the cooling zone. The cooled air then enters the switch body through an L-shaped square tube, further reducing the internal temperature of the switch. This ensures stable and smooth operation of the electronic components within the switch, preventing network lag and disconnections caused by high temperatures. This tiered cooling system is also energy-efficient, preventing excessive power consumption. This mechanism enables the network switch to have multi-stage cooling capabilities, improving its protection, ensuring smooth network operation, enhancing stability, and allowing for different cooling levels based on varying heat levels, thus preventing excessive power consumption and improving the switch's energy-saving performance.

[0023] 2. Through the waterproof mechanism, when the environment where the network switch is placed is too humid, the humidity sensor will detect the humidity in real time and convert the humidity value into an electrical signal, which is then sent to the PLC controller. If the humidity detected by the humidity sensor exceeds the preset warning humidity threshold of the PLC controller, the PLC controller will control the semiconductor cooling chip and the air intake mechanism to work. The semiconductor cooling chip lowers the temperature of the cooling zone. Then, as the humid outside air supplied from the U-shaped metal tube passes through the low-temperature first metal mesh, the moisture in the air liquefies into water droplets at low temperatures. These water droplets adhere to the first metal mesh, and the impeding effect of the breathable support cover and the waterproof and breathable membrane cover further filters out the moisture in the air. Dry air is delivered to the switch body and sprayed outwards from inside the switch body, further preventing external humid air from entering the switch body. This keeps the internal environment of the switch body dry, preventing humid air from condensing into water droplets that could cause short circuits. It also prevents moisture from corroding the internal electronic components of the switch body and prevents mold growth that could damage the insulation. This mechanism gives the network switch highly effective waterproofing in harsh environments, ensuring network smoothness, extending the switch's lifespan, reducing maintenance costs, and ultimately improving the stability and performance of the switch.

[0024] 3. Through the installed drain valve, water pressure sensor, and buzzer alarm, as the water flow in the storage area increases, the water pressure sensor will detect the water level in real time and convert the water pressure value into an electrical signal to send to the PLC controller. If the water pressure in the storage area exceeds the water pressure threshold preset by the PLC controller, it indicates that the water level in the storage area is too high, and there is a possibility that abnormal water conditions may interfere with the environment where the network switch is placed. At this time, the PLC controller will promptly activate the buzzer alarm to alert the staff to handle the situation in time. The staff can open the drain valve, and the water in the storage area will be drained into the collection container. This mechanism enables the network switch to have an alarm function, ensuring the safety of the network switch during operation. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1-6 As shown, a waterproof network switch includes a switch body 1, a protective box 2 fixedly connected to the lower surface of the switch body 1, a vertical partition 3 fixedly connected to the inner wall of the protective box 2, and a horizontal partition 4 fixedly connected to the outer wall of the vertical partition 3 and the inner wall of the protective box 2. The vertical partition 3 and the horizontal partition 4 together divide the internal cavity of the protective box 2 into an air intake area 10, a cooling area 11 and a water storage area 12. The side wall of the switch body 1 is provided with multiple mounting holes, and an exhaust pipe 20 is fixedly connected to the hole wall of the mounting hole.

[0034] An air intake mechanism 5 is fixedly connected to the inner wall of the air intake zone 10 of the protective box 2. The air intake mechanism 5 includes a miniature air pump 51. The bottom end of the miniature air pump 51 is fixedly connected to the inner wall of the bottom end of the protective box 2. A threaded cylinder 52 is fixedly connected to the side wall of the protective box 2 in the air intake zone 10. The side end of the threaded cylinder 52 is fixedly connected to the air intake end of the miniature air pump 51. A filter assembly 6 is threadedly sealed to the inner wall of the threaded cylinder 52. A bent pipe 53 is fixedly connected to the air outlet end of the miniature air pump 51. A round hole is opened at the bottom end of the vertical partition 3. A U-shaped metal pipe 54 is fixedly connected to the wall of the round hole. The air outlet end of the U-shaped metal pipe 54 passes through the upper surface of the horizontal partition 4 and is connected to the cavity of the protective box 2 in the cooling zone 11. The air outlet end of the bent pipe 53 is fixedly connected to the air intake end of the U-shaped metal pipe 54. This mechanism enables the network switch to have a heat dissipation function.

[0035] The filter assembly 6 includes a connecting ring 61 that is threadedly sealed to the inner wall of the side end of the threaded cylinder 52. A filter screen 62 is fixedly connected to the inner wall of the connecting ring 61. A U-shaped limiting bracket 63 is fixedly connected to the side of the connecting ring 61 away from the filter screen 62. A sponge filter block 64 is movably connected to the U-shaped limiting bracket 63 and the inner wall of the connecting ring 61. This mechanism can filter the outside air drawn in by the air intake mechanism 5. Moreover, the sponge filter block 64 of the filter assembly 6 is replaced periodically, so that the filter assembly 6 can reliably purify the outside air drawn in by the air intake mechanism 5 for a long time, and the air intake volume of the air intake mechanism 5 will not be significantly reduced due to the clogging of the sponge filter block 64.

[0036] A rectangular through hole is formed on the upper surface of the horizontal partition 4, and a waterproof mechanism 7 is fixedly connected to the wall of the rectangular through hole. The waterproof mechanism 7 includes a semiconductor cooling chip 71 fixedly connected to the horizontal partition 4. A plurality of first metal mesh sheets 72 are fixedly connected to the cooling side surface of the semiconductor cooling chip 71. A fixing hole is formed on the upper surface of the horizontal partition 4, and a discharge check valve 73 is fixedly connected to the wall of the fixing hole. An exhaust pipe 74 is fixedly connected to the side wall of the protective box 2 located in the water storage area 12. A rectangular hole is formed at the top of the vertical partition 3, and the wall of the rectangular hole is fixedly connected to... There is an L-shaped square tube 75, the air outlet of which passes through the top of the protective box 2 and is fixedly connected to the lower surface of the switch body 1. The air inlet of the L-shaped square tube 75 is fixedly sleeved with a breathable support cover 76. The inner wall of the breathable support cover 76 is fixedly connected with a waterproof and breathable membrane cover 77. The waterproof and breathable membrane cover 77 is made of polytetrafluoroethylene (PTFE) membrane. PTFE membrane has excellent high and low temperature resistance and chemical stability. Through stretching and other processes, a microporous structure is formed, which can achieve a balance between waterproofing and breathability. This mechanism enables the network switch to have a waterproof function.

[0037] A PLC controller 13 is fixedly connected to the inner wall of the protective box 2 in the air intake area 10. A temperature sensor 14 and a humidity sensor 15 are fixedly embedded on the top outer wall of the protective box 2 in the air intake area 10. A detection through hole that matches the detection end of the temperature sensor 14 is opened on the lower surface of the switch body 1. Multiple second metal meshes 8 are fixedly connected to the heat dissipation side surface of the semiconductor cooling chip 71. A drain valve 9 is fixedly connected to the bottom outer wall of the protective box 2 in the water storage area 12. A water pressure sensor 16 is fixedly connected to the bottom inner wall of the protective box 2 in the water storage area 12. A buzzer alarm 17 is fixedly embedded on the side wall of the protective box 2 in the air intake area 10.

[0038] Anti-slip support blocks 18 are fixedly connected to the four corners of the lower surface of the protective box 2, and limiting rings 19 that cooperate with the anti-slip support blocks 18 are fixedly connected to the four corners of the upper surface of the switch body 1. When multiple network switches are used at the same time, multiple network switches can be stacked. During the stacking process, the anti-slip support block 18 of the previous network switch can be inserted into the limiting ring 19 of the next network switch, ensuring the stability of the stacking of multiple network switches, thereby reducing the space occupied by multiple network switches when they are placed.

[0039] The miniature air pump 51 and the semiconductor cooling chip 71 are both electrically connected to the output terminal of the PLC controller 13 via wires. The temperature sensor 14, humidity sensor 15 and water pressure sensor 16 are all electrically connected to the input terminal of the PLC controller 13 via wires. The above electrical components and electrical connections are all existing technologies and will not be described in detail here.

[0040] The operating principle of this invention is described as follows: When the network switch is operating in a simple environment, the temperature sensor 14 first monitors the internal temperature of the switch body 1 and converts the temperature into an electrical signal, which is then sent to the PLC controller 13. If the internal temperature of the switch body 1 exceeds the first temperature threshold preset by the PLC controller 13 (e.g., 25 degrees Celsius), the PLC controller 13 controls the micro air pump 51 to operate. The micro air pump 51 draws in outside air through the threaded cylinder 52. During the air intake process, the air is filtered by the filter screen 62 and the sponge filter block 64 to remove impurities from the air, ensuring that the air injected into the switch body 1 is clean and achieving a dustproof effect, thus preventing the accumulation of a large amount of dust and impurities inside the switch body 1. Afterward, the micro air pump 51 delivers the air to the cooling zone 11 through the bent pipe 53 and the U-shaped metal pipe 54. Finally, the air passes through the breathable support cover 76. The waterproof and breathable membrane cover 77 and the L-shaped square tube 75 are injected into the switch body 1 to increase the airflow inside the switch body 1. The increased airflow enables efficient heat dissipation inside the switch body 1. After heat dissipation, the air is discharged through the exhaust pipe 20 or through the heat dissipation holes on the switch body 1. Due to the large ventilation cross-sectional area of ​​the L-shaped square tube 75 and the large membrane area of ​​the waterproof and breathable membrane cover 77, about 80%-90% of the air in the cooling zone 11 enters the L-shaped square tube 75, while the remaining 10%-20% of the air enters the water storage zone 12 through the exhaust one-way valve 73 and is finally discharged through the exhaust pipe 74. Moreover, this part of the air passes through the heat dissipation side of the semiconductor cooling chip 71, which can accelerate the airflow on the heat dissipation side of the semiconductor cooling chip 71, improve the heat dissipation effect of the heat dissipation side of the semiconductor cooling chip 71, and thus ensure the cooling effect of the semiconductor cooling chip 71.

[0041] If the ambient temperature of the switch is too high, affecting the heat dissipation of the switch body 1, and the temperature sensor 14 detects that the temperature inside the switch body 1 continues to rise and reaches the second temperature threshold preset by the PLC controller 13 (e.g., 35 degrees Celsius), then the PLC controller 13 not only controls the micro air pump 51 to work, but also controls the semiconductor cooling chip 71 to work. The cooling side of the semiconductor cooling chip 71 cools down, and at the same time, the cooling side of the semiconductor cooling chip 71 lowers the temperature of the first metal mesh 72 and the cooling zone 11. Then, the outside air transported by the U-shaped metal tube 54 is cooled by the semiconductor cooling chip 71 and the first metal mesh 72 in the cooling zone 11. The cooled air is then passed through... The air enters the switch body 1 through the L-shaped square tube 75. The low-temperature air entering the switch body 1 can more quickly reduce the internal temperature of the switch body 1, making the electronic components inside the switch body 1 operate stably and ensuring smooth network operation. It will not cause network lag or network dropout due to high temperature environment. Moreover, this graded cooling is more energy-saving and will not consume too much energy. This mechanism enables the network switch to have a multi-level cooling function, improves the protection capability of the switch, effectively ensures smooth network operation, improves the stability of the switch, and can achieve different levels of cooling effect according to different heat conditions, avoiding excessive energy consumption of the network switch and improving the energy-saving performance of the switch.

[0042] When the environment where the network switch is placed is too humid, the humidity sensor 15 will detect the humidity of the environment and convert the humidity value into an electrical signal, which will be sent to the PLC controller 13. If the humidity detected by the humidity sensor 15 exceeds the preset warning humidity threshold of the PLC controller 13, the PLC controller 13 will control the semiconductor cooling chip 71 and the air intake mechanism 5 to work. The semiconductor cooling chip 71 will lower the temperature of the cooling zone 11. Then, as the humid outside air transported from the U-shaped metal tube 54 passes through the low-temperature first metal mesh 72, the moisture in the air will liquefy into water droplets. The water droplets will adhere to the first metal mesh 72, and as the water droplets accumulate, they will converge into a small stream that flows to the upper surface of the partition plate 4. Furthermore, due to the obstruction of the breathable support cover 76 and the waterproof and breathable membrane cover 77, the moisture in the air will be further filtered out. The moisture in the air will accumulate at the partition plate 4, and the water flow at the partition plate 4 will continue to flow through the partition plate 4. The airflow from the one-way valve 73 is carried into the water storage area 12, where the water is stored under gravity. The air is discharged through the exhaust pipe 74, and then the dry air is injected into the switch body 1 through the L-shaped square pipe 75. The dry air is also sprayed outward from the inside of the switch body 1, further preventing the intrusion of external humid air into the switch body 1. This keeps the internal environment of the switch body 1 dry and prevents humid air from accumulating into water droplets inside the switch body 1 and causing short circuits. It also prevents moisture from corroding the internal electronic components of the switch body 1 and prevents mold growth inside the switch body 1 from damaging the insulation. This mechanism enables the network switch to have a highly efficient waterproof function in harsh environments, ensuring network smoothness, increasing the service life of the switch, reducing the maintenance cost of the switch, and thus improving the stability and effectiveness of the switch.

[0043] As the water flow in the water storage area 12 increases, the water pressure sensor 16 monitors the water level in the water storage area 12 in real time and converts the water pressure value into an electrical signal, which is then sent to the PLC controller 13. If the water pressure in the water storage area 12 exceeds the preset water pressure threshold of the PLC controller 13, it indicates that the water level in the water storage area 12 is too high, and there is a possibility that abnormal water levels may interfere with the environment where the network switch is placed. At this time, the PLC controller 13 promptly controls the buzzer alarm 17 to sound an alarm, which alerts the staff to handle the situation promptly. The staff opens the drain valve 9, and the accumulated water in the water storage area 12 is drained into the collection container through the drain valve 9. Moreover, the water level height in the water storage area 12 corresponding to the preset water pressure threshold of the PLC controller 13 is half the height of the water storage area 12. That is, at this time, there is still a certain height difference between the water level in the water storage area 12 and the exhaust pipe 74. This height difference is redundant. The design incorporates features such as the ability to continue storing water in the water storage area 12 even after the buzzer alarm 17 sounds during unattended nighttime hours. This prevents water from overflowing and damaging the switch during unattended periods. Furthermore, the limited air extraction capacity of the miniature air pump 51 slows down the accumulation of water in the water storage area 12, minimizing the risk of overflow before personnel arrive the next day. Upon arrival, personnel will immediately receive the alarm from the buzzer 17 and promptly drain the water from the storage area 12, ensuring its continued reliable operation. Even if some water overflows from the exhaust pipe 74, the water will be guided away from the switch body 1 by the exhaust pipe 74 and will not enter the switch body 1. This mechanism provides the network switch with an alarm function, ensuring its operational safety.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
