Description
Technical Field
[0001] This utility model relates to the field of switch technology, and in particular to a dustproof optoelectronic switch. Background Technology
[0002] As a core device in modern communication networks, optoelectronic switches are widely used in data centers, industrial control, and intelligent buildings. Their stability and reliability directly affect the performance of the entire network system. However, in dusty, humid, or highly polluted environments, traditional optoelectronic switches face severe challenges. Dust and particulate matter can easily enter the device through heat dissipation holes or interface gaps, adhering to circuit boards, optical modules, and heat dissipation devices, leading to reduced heat dissipation efficiency, decreased signal transmission quality, and even short circuits or component damage. Therefore, developing an optoelectronic switch with high-efficiency dustproof capabilities has become an important research direction for improving the environmental adaptability and long-term reliability of equipment.
[0003] Currently, most optoelectronic switches on the market adopt passive dustproof designs, such as metal mesh covers, dustproof sponges, or labyrinth-style heat dissipation structures. Metal mesh covers block large dust particles through fine mesh holes, but they are prone to clogging and difficult to clean. Although dustproof sponges can absorb fine dust, they will reduce air permeability and affect heat dissipation efficiency after long-term use. Some high-end devices use electrostatic dust removal or centrifugal fan-assisted filtration, but these solutions are complex in structure, expensive, and require regular maintenance. In terms of interface protection, the common practice is to use rubber dust plugs or flip-top protective covers, but these designs often require manual operation, resulting in a poor user experience in scenarios with frequent plugging and unplugging, and the protection is prone to failure due to human negligence.
[0004] Although existing technologies can reduce dust intrusion to some extent, they still have significant drawbacks. Traditional dust filters are prone to clogging after long-term use, which increases the resistance of the heat dissipation airflow and seriously affects the heat dissipation efficiency. At the same time, due to the lack of convenient disassembly and locking mechanisms, the replacement and cleaning of filters is cumbersome and may even require shutdown, affecting the continuous operation of the equipment. To address these issues, a dustproof photoelectric switch is proposed. Utility Model Content

[0033] 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.
[0034] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a dustproof photoelectric switch, comprising a switch body 1, which is typically made of engineering plastic or aluminum alloy, providing structural support and protection for the internal electronic components of the entire switch. The switch body 1 is prior art and will not be described in detail here. Filter components are provided on the left and right sides of the switch body 1 to filter the air entering the switch and prevent dust and other impurities from damaging the internal components. Protective components are provided on the side walls of the switch body 1 to protect the network ports of the switch.
[0035] The filter assembly includes a protective frame 6, which is made of metal. The sidewalls of the protective frame 6 are bolted to the outer wall of the exchanger body 1, serving to protect the filter plate 7 and guide airflow. The filter plate 7, made of porous filter material, is slidably connected inside the protective frame 6 to adsorb and filter dust particles from the air. A handle 8, made of plastic, is fixedly connected to one side of the filter plate 7, facilitating the removal and removal of the filter plate 7 for cleaning or replacement. A symmetrical locking box 10 is fixedly connected to the other side of the filter plate 7. The locking box 10 is made of plastic and is used to house the limiting components. Each side of the locking box 10 has a locking block 9, which is made of metal and has grooves on both sides for engaging with the limiting components to restrict the position of the filter plate 7. The side walls of the locking blocks 9 are fixedly connected to the inside of the protective frame 6, and the outer walls of the locking blocks 9 are slidably connected to the inside of the locking box 10. The locking box 10 has symmetrically arranged upper and lower limiting components inside. These limiting components restrict the position of the locking blocks 9, thereby restricting the position of the filter plate 7. The limiting components include a limiting ball 11, which is made of stainless steel. Limiting plates 12 are fixedly connected to the side walls of the locking box 10 to transmit the elastic force of the limiting springs 13 and limit the movement range of the limiting ball 11. The limiting ball 11 and the outer walls of the limiting plates 12 are slidably connected inside the locking box 10. Limiting springs 13 are provided on the sides of the limiting plates 12. The limiting springs 13 are made of spring steel. One end of each limiting spring 13 is fixedly connected to the inside of the locking box 10, and the other end is fixedly connected to the side wall of the limiting plates 12 to provide a restoring force for the limiting ball 11, so that it can be locked into the groove after the locking block 9 is inserted. Currently locked, a power interface 2 and a data interface 3 are fixedly connected to one side of the outer wall of the switch body 1. The power interface 2 and the data interface 3 are located on the back of the switch body 1. The power interface 2 is used to connect the power cord to power the switch, and the data interface 3 is used to connect the data cable to realize data transmission. An indicator light 5 and multiple indicator marks 4 are fixedly connected to the other side of the outer wall of the switch body 1. The indicator light 5 and the indicator marks 4 are both located on the front of the switch body 1. The indicator light 5 is used to display the working status of the switch. The indicator marks 4 are made of plastic and are used to mark the location of the network ports of the switch. The indicator marks 4 are located below the protective components.
[0036] Specifically, when using this dustproof optoelectronic switch, the operator first aligns the power cord plug with the power interface 2 on the back of the switch body 1 and inserts the power cord plug into the power interface 2 to provide power to the switch. Next, the operator inserts the data cable plug into the data interface 3 to establish a data connection between the switch and external devices. Then, the operator observes the indicator light 5 on the front of the switch body 1. Indicator light 5 is connected to the switch's power and operating status monitoring module through an internal circuit. If indicator light 5 is lit, it indicates that the switch is normally powered on and in working condition. During use, the internal cooling device of the switch activates, generating suction to draw outside air from the switch body 1. Air enters through the filter components on both sides. First, it passes through the filter plate 7, which isolates dust, hair, and other debris from the air. Clean air then enters the equipment through the pores of the filter plate 7, flowing over the heated electronic components. Cooling is achieved through heat conduction and convection, and the air is finally discharged from the heat dissipation holes of the exchanger. When the filter plate 7 needs to be replaced or cleaned, the operator holds the handle 8 and applies a horizontal pulling force outward. The filter plate 7 slides linearly outward along the sliding track inside the protective frame 6, which in turn causes the locking box 10 inside its side wall to move outward synchronously. The displacement of the locking box 10 causes the limiting ball 11 inside it to lock against the locking block on the side wall of the protective frame 6. Upon contact with the locking block 9, the outer wall of the locking block 9 applies lateral pressure to the limiting ball 11. Under the pressure of the locking block 9, the limiting ball 11 slides into the locking box 10, simultaneously pushing the limiting plate 12 to move linearly inward into the locking box 10. The displacement of the limiting plate 12 causes the limiting spring 13 to be compressed. When the filter plate 7 slides outward until the limiting ball 11 is completely disengaged from the groove of the locking block 9, the locking block 9 is completely disengaged from the locking box 10, and the filter plate 7 loses its limiting constraint. The operator can then completely remove the filter plate 7 from the protective frame 6 for cleaning or replacement. When installing a new filter plate 7, the operator aligns the filter plate 7 with the inlet of the protective frame 6 and applies water inward. With a flat pushing force, the filter plate 7 slides inward along the sliding track inside the protective frame 6 until the locking box 10 of the filter plate 7 is aligned with the locking block 9 of the protective frame 6. At this time, the locking block 9 is inserted into the locking box 10, and the outer wall of the locking block 9 presses the limiting ball 11 again. The limiting ball 11 slides into the locking box 10 and compresses the limiting spring 13. When the locking block 9 slides to the preset position, the recesses on both sides of the locking block 9 move to the corresponding positions of the limiting ball 11. The limiting spring 13 releases its elastic potential energy, pushing the limiting plate 12 and the limiting ball 11 to reset towards the locking block 9. The limiting ball 11 is locked into the recesses on both sides of the locking block 9, realizing the mechanical locking of the filter plate 7.
[0037] Reference Figure 4 and Figure 5The protective components include a second protective frame 14, made of aluminum alloy, which has a certain strength and wear resistance. The sidewalls of the second protective frame 14 are fixedly connected to the outer wall of the switch body 1 by bolts, protecting the network port 18 and providing a sliding track for the partition 15. Multiple network port 18 are arranged in an array inside the second protective frame 14, each integrating a network connection terminal for inserting a network cable plug to achieve data transmission. Multiple sliding grooves 17 are provided on the top of the second protective frame 14, positioned corresponding to the network port 18 and communicating with the inside of the grooves. These grooves accommodate the partition 15 and guide its vertical sliding. Each groove 17 has a slidably connected partition 15, made of engineering plastic, and each partition 15 has a handle fixedly connected to its top. 16. Handle 2 is made of engineering plastic with anti-slip texture on the surface, making it easy for workers to lift the partition 15. The left and right sides of the protective frame 2 are equipped with symmetrical upper and lower limit balls 21. The side walls of the limit balls 21 are fixedly connected to limit plates 20, which are used to transmit the elastic force of the limit springs 29 and limit the movement range of the limit balls 21. The outer walls of the limit balls 21 and the limit plates 20 are slidably connected inside the protective frame 24. The side of the limit plates 20 is equipped with limit springs 29, which are made of spring steel. One end of the limit springs 29 is fixedly connected inside the protective frame 24, and the other end of the limit springs 29 is fixedly connected to the side wall of the limit plates 20, which is used to provide a restoring force for the limit balls 21, so that they can be locked into the hole after the partition 15 slides into place.
[0038] Specifically, based on actual usage needs, the staff determines the location of the network port 18 that needs to be opened. The staff then pulls the handle 16 upwards, causing the partition 15 to slide linearly upwards along the inner wall of the groove 17 inside the protective frame 14. Simultaneously, the outer walls of the partition 15 contact the limiting ball 21 inside the protective frame 14, applying lateral pressure. Under the pressure of the partition 15, the limiting ball 21 slides linearly inwards towards the protective frame 14, simultaneously pushing the limiting plate 20 to move linearly inwards towards the protective frame 14. The displacement of the limiting plate 20 causes the limiting spring 19 to compress. When the partition 15 slides upwards to a certain position, the limiting ball 21 no longer limits the side walls of the partition 15, and the operation... As the operator continues to pull handle 16 upwards, partition 15 continues to slide upwards. When the hole at the bottom of partition 15 moves to the corresponding position of top limiting ball 21, the previously compressed top limiting spring 19 begins to release its elastic potential energy, pushing limiting plate 20 to move linearly towards partition 15. Limiting plate 20 drives limiting ball 21 to move synchronously, causing limiting ball 21 to engage with the hole at the bottom of partition 15, fixing the position of partition 15. At this time, network port 18 is fully exposed. The operator inserts the network cable plug into network port 18 to establish a network connection. Through the up-and-down sliding of partition 15 and the limiting action of limiting ball 21, partition 15 can prevent dust from entering when network port 18 is not in use, achieving the effect of preventing dust from entering network port 18.
[0039] Working principle: When using this dustproof optoelectronic switch, the operator first inserts the power cord and data cable into the power interface 2 and data interface 3 in sequence. Then, observe the indicator light 5 to ensure that the device is working properly. Then, according to the actual usage requirements, confirm the network port 18 that needs to be opened. At this time, the operator manually pulls the handle 16 upward. The displacement of the handle 16 causes the partition 15 to slide upward on the inner wall of the slide groove 17. While the partition 15 slides, its outer walls on both sides press the limiting ball 21, causing the limiting ball 21 and the limiting plate 20 to slide into the protective frame 14, and at the same time press the limiting spring 19. At this time, the limiting ball 21 no longer limits the side wall of the partition 15. The operator continues to pull upward, and then the limiting spring 19 at the top pushes the limiting ball 21 into the hole at the bottom of the partition 15, fixing the position of the partition 15. Then, the operator inserts the network cable plug into the network port 18, thereby achieving the effect of preventing dust from entering the network port 18.
[0040] During equipment use, its internal heat dissipation device draws in air from the outside to cool the internal components. The air first passes through the filter plate 7, isolating dust and other debris on the outside. Clean air then enters the equipment to cool the components. When the filter plate 7 needs to be replaced or cleaned, the operator pulls it outward using handle 8. The displacement of the filter plate 7 causes the locking box 10 inside its side wall to move as well. The displacement of the locking box 10 then causes the limiting ball 11 inside it to move as well, thus locking the device. Under the pressure of the outer wall of block 9, the limiting ball 11 retracts into the locking box 10, and the limiting spring 13 is compressed. At this time, the locking block 9 is completely disengaged from the locking box 10, and the operator can take out the filter plate 7. During installation, the filter plate 7 is inserted into the protective frame 6, so that the locking block 9 on the side wall of the protective frame 6 is inserted into the locking box 10 again. The limiting spring 13 pushes the limiting ball 11 into the recesses on both sides of the locking block 9, thereby completing the fixation of the filter plate 7, thus achieving the effect of quick disassembly and assembly of the filter plate 7 and preventing dust from entering the equipment.
