Description

Technical Field

[0001] This application relates to the technical field of equipment waterproofing, and in particular to a protective device and electronic equipment. Background Technology

[0002] Currently, air outlets on direct ventilation equipment typically use protective louvers with waterproof ratings of IPX (International Protection Rating) 3 or IPX4. When the waterproof rating reaches IPX5, double-layer horizontal labyrinth louvers are used to ensure a large heat dissipation area. However, existing protective louvers have complex structures and high design and production costs. When equipment size is limited and the air outlet area is small, current protective louvers cannot guarantee effective heat dissipation. Utility Model Content

[0003] This application provides a protective device to solve the problems of existing protective devices having large space requirements and poor waterproofing effect.

[0004] To address the aforementioned technical problems, this application provides a protective device, comprising: a housing with an accommodating space formed within it, an air inlet and an air outlet formed on the housing, the air inlet and air outlet being connected through the accommodating space; and a waterproof component disposed within the accommodating space, the waterproof component including a first waterproof part and a second waterproof part, the first waterproof part and the second waterproof part being offset from each other on the inner sidewall of the housing, the first waterproof part being disposed closer to the air outlet, and the second waterproof part being disposed further away from the air outlet.

[0005] The housing includes multiple sidewalls. A first waterproof part is disposed on the sidewall at the upper edge of the air outlet, and the angle between the first waterproof part and the plane of the air outlet is less than 90°. A second waterproof part is disposed on the sidewall opposite to the air outlet, and the angle between the plane of the second waterproof part and the plane of the air inlet is less than 90°. The second waterproof part is located above the first waterproof part so that the first and second waterproof parts are staggered.

[0006] Among them, the sidewall connected to the lower edge of the air outlet has an angle of less than 90° with the plane where the air outlet is located and is distributed opposite to the air inlet.

[0007] The projections of the first waterproof section and the second waterproof section on the plane where the air inlet is located cover the air inlet.

[0008] The first waterproof part includes a first support member and a plurality of first water-blocking plates. The first support member has a plurality of first through holes, and the first water-blocking plates are arranged in a one-to-one correspondence with the first through holes. One end of the first water-blocking plate is connected to the side of the first support member near the air outlet, and the other end of the first water-blocking plate is spaced apart from the first through holes. Along the direction perpendicular to the plane where the first support member is located, the first water-blocking plates cover the first through holes.

[0009] The two sides of the first through hole are bent away from the first water baffle to form the first baffle, and the distance between the two first baffles gradually decreases along the axis of the opening of the first through hole.

[0010] The second waterproof part includes a second support member and a plurality of second water-blocking plates. The second support member has a plurality of second through holes, and the second water-blocking plates are arranged in a one-to-one correspondence with the second through holes.

[0011] The second water baffle is located on the side of the second support member away from the air inlet, and covers the second through hole in a direction perpendicular to the second support member.

[0012] Among them, the second support member is provided with several second baffles on the side near the air inlet, and the second baffles correspond one-to-one with the second through holes.

[0013] The second support member has a water-blocking strip at its end near the first waterproof part, and the water-blocking strip extends away from the air inlet.

[0014] The housing is equipped with protective components, which are located at the air outlet. The protective components include a bracket and a protective net. The bracket is detachably connected to the housing, and the protective net is located inside the bracket.

[0015] The protective device also includes a fan assembly, which is located at the air inlet of the housing, and the air outlet of the fan assembly is connected to the accommodating space.

[0016] To address the aforementioned problems, this application also provides an electronic device, including: a protective device, wherein the protective device is any of the protective devices described above.

[0017] The beneficial effects of this application are as follows: Unlike the prior art, this application opens an air inlet and an air outlet on the housing, and sets a first waterproof part and a second waterproof part on the inner side wall of the housing in a staggered manner, with the first waterproof part set close to the air outlet and the second waterproof part set close to the air inlet. This allows for multiple barriers to rainwater through the first and second waterproof parts, effectively improving the waterproof performance of the protective equipment. Furthermore, the staggered arrangement of the first and second waterproof parts reduces the volume occupied by the protective equipment and reduces the layout pressure when the protective equipment is installed in other devices.

[0030] Please see Figure 1 , Figure 1This is a schematic diagram of an embodiment of the protective device provided in this application.

[0031] This application provides a protective device. For example... Figure 1 As shown, the protective device of this embodiment includes a housing 10 and a waterproof component 20. A receiving space 101 is formed within the housing 10, and an air inlet 102 and an air outlet 103 are formed on the housing 10, communicating through the receiving space 101. The air inlet 102 and air outlet 103 are located adjacent to each other on adjacent inner sidewalls of the housing; for example, the air inlet 102 is located on the inner sidewall at the upper end of the housing 10, and the air outlet 103 is located on the inner sidewall on the side of the housing 10.

[0032] Generally speaking, outdoor electronic devices require heat dissipation during use, which necessitates ventilation. However, on rainy days, rainwater can enter the device through these ventilation openings, potentially damaging it. While louvers are typically installed at these ventilation points, they offer some degree of waterproofing, but their effectiveness is limited.

[0033] In an optional embodiment, combined with Figure 8As shown, a receiving space 101 is formed on the housing 10, and an air inlet 102 and an air outlet 103 connected to the air inlet 102 are provided on the housing 10. That is, the air outlet 103 and the air inlet 102 are connected through the receiving space 101, and air inside the device 50 can enter the receiving space 101 through the air inlet 102 and be transported through the air outlet 103. In other words, hot air inside the device 50 can be discharged through the air inlet 102 and the air outlet 103, thereby dissipating heat from the device 50. To prevent rainwater from entering the device 50, a waterproof component 20 is provided within the accommodating space 101 of the housing 10. The waterproof component 20 includes a first waterproof part 201 and a second waterproof part 202, which are disposed on the inner sidewall 104 of the housing 10. The first waterproof part 201 and the second waterproof part 202 are staggered. On the one hand, this ensures that hot air inside the device 50 is discharged through the air outlet 103; on the other hand, it prevents rainwater from entering the device 50 through the air outlet 103 on the housing 10. The first waterproof part 201 is located close to the air outlet 103, and the second waterproof part 202 is located away from the air outlet 103. When rainwater falls on the housing 10, it will enter through the air outlet 103. When rainwater enters, the first waterproof part 201 can block the rainwater, preventing it from entering the device 50 through the accommodating space 101, and the second waterproof part 202 can further block the rainwater.

[0034] In this embodiment, the air outlet 103 of the housing 10 is connected to the inner wall 104 of the device 50 to house the protective device inside the device 50. This allows hot air inside the device 50 to enter the accommodating space 101 through the air inlet 102 and be discharged through the air outlet 103, thus ensuring heat dissipation of the device 50. When it is raining, rainwater will enter the accommodating space 101 of the housing 10 through the air outlet 103. When rainwater enters the accommodating space 101, the first waterproof part 201 will block the rainwater, reducing the amount of rainwater entering the device 50 through the accommodating space 101 and preventing water immersion and damage. Furthermore, by offsetting the second waterproof part 202 from the first waterproof part 201, after some rainwater enters the accommodating space 101, the second waterproof part 202 can further block the rainwater, further reducing the amount of rainwater entering the device 50. The housing 10 is detachably connected to the device 50, meaning the housing 10 can be fixed inside the device 50 using screws and nuts. Similarly, the first waterproof part 201 and the second waterproof part 202 are fixed to the housing 10 using screws and nuts. Other fixing methods can also be used, such as welding, which are not specifically limited here.

[0035] In an optional embodiment, the first waterproof part 201 is disposed near the air outlet 103 on the housing 10, and the second waterproof part 202 is disposed near the air inlet 102. Specifically, the first waterproof part 201 is disposed at a preset angle to the plane of the air outlet 103, and the second waterproof part 202 is disposed at a preset angle to the plane of the air inlet 102. When the waterproof component 20 is disposed inside the housing 10, the second waterproof part 202 is disposed above the first waterproof part 201, thereby preventing rainwater from entering the device 50 through the air inlet 102. That is, by providing the first waterproof part 201 and the second waterproof part 202, the waterproofness of the protective device 50 can be effectively improved. In this embodiment, by staggering the first waterproof part 201 and the second waterproof part 202 within the housing 10, the volume occupied by the protective device can be reduced. When the protective device is placed inside the device 50, the layout pressure of the device 50 can be reduced, thereby facilitating the installation of other components inside the device 50 and ensuring the ventilation requirements of the small-sized device 50.

[0036] By using the above method, by opening an air inlet 102 and an air outlet 103 on the housing 10, and by staggering the first waterproof part 201 and the second waterproof part 202 on the inner sidewall 104 of the housing 10, with the first waterproof part 201 located near the air outlet 103 and the second waterproof part 202 located near the air inlet 102, multiple barriers to rainwater can be provided by the first waterproof part 201 and the second waterproof part 202, effectively improving the waterproof performance of the protective device 50. Furthermore, the staggered arrangement of the first waterproof part 201 and the second waterproof part 202 can reduce the volume occupied by the protective device 50 and reduce the layout pressure when the protective device 50 is installed in other devices.

[0037] In an optional embodiment, such as Figure 2As shown, the housing 10 includes multiple sidewalls 104, which are connected sequentially to form an accommodating space 101. A first waterproof part 201 is disposed on the sidewall 104 at the upper edge of the air outlet 103, and the angle between the first waterproof part 201 and the plane of the air outlet 103 is less than 90°. A second waterproof part 202 is disposed on the sidewall 104 opposite to the air outlet 103. The angle between the sidewall 104 connected at the lower edge of the air outlet 103 and the plane of the air outlet 103 is less than 90°. The projections of the first waterproof part 201 and the second waterproof part 202 onto the plane of the air inlet 102 completely cover the air inlet 102. Multiple sidewalls 104 are connected in sequence to form an accommodating space 101. A first waterproof part 201 is disposed on the sidewall 104 at the upper edge of the air outlet 103, that is, at the connection point between the sidewall 104 where the air inlet 102 is located and the sidewall 104 where the air outlet 103 is located. The angle between the plane of the first waterproof part 201 and the plane of the air outlet 103 is less than 90°, for example, 30°, 45°, etc., thereby effectively blocking rainwater. The angle between the plane of the second waterproof part 202 and the plane of the air inlet 102 is less than 90°, and the second waterproof part 202 is disposed at the edge of the sidewall 104 of the air inlet 102 away from the air outlet 103. Therefore, the second waterproof part 202 is disposed above the first waterproof part 201, and when rainwater enters the accommodating space 101, it can be blocked by the first waterproof part 201 and the second waterproof part 202.

[0038] In this embodiment, the angle between the plane of the first waterproof part 201 and the plane of the air outlet 103 is less than 90°, and the angle between the plane of the second waterproof part 202 and the plane of the air inlet 102 is less than 90°. The second waterproof part 202 is located above the first waterproof part 201, so that the first waterproof part 201 and the second waterproof part 202 are staggered. This ensures that hot air inside the equipment enters the accommodating space 101 through the air inlet 102 and is discharged through the air outlet 103, improving the heat dissipation efficiency inside the equipment. Furthermore, the staggered arrangement of the first waterproof part 201 and the second waterproof part 202 effectively reduces the amount of rainwater entering the equipment when it hits the equipment, thereby preventing damage to the electronic components inside the equipment.

[0039] In an optional embodiment, the projections of the first waterproof portion 201 and the second waterproof portion 202 onto the plane of the air inlet 102 cover the air inlet 102. Normally, when rainwater hits the inner wall 104 of the housing 10, the rainwater splashes under the impact, allowing some rainwater to enter the device 50 through the air inlet 102. By covering the air inlet 102 with the projections of the first waterproof portion 201 and the second waterproof portion 202, rainwater can be blocked. In rainy weather, the first waterproof part 201 can block rainwater in advance, thereby preventing rainwater from entering the housing space 101 of the housing 10. However, after some rainwater passes through the first waterproof part 201 and hits the inner wall 104 of the housing 10, the second waterproof part 202 can block the splashed rainwater. Thus, the first waterproof part 201 and the second waterproof part 202 effectively block the rainwater, thereby improving the waterproof performance of the protective device.

[0040] In other embodiments, the projections of the first waterproof part 201 and the second waterproof part 202 on the plane where the air inlet 102 is located completely cover the air inlet 102. The specific settings can be made according to actual needs or manufacturing processes, and this application does not make specific limitations here.

[0041] In an optional embodiment, the side wall 104 on the housing 10 opposite to the air inlet 102 is inclined, that is, the angle between the side wall 104 opposite to the air inlet 102 and the plane where the air inlet 102 is located is less than 90°. At the same time, the angle between the side wall 104 opposite to the air inlet 102 and the plane where the air outlet 103 is located is less than 90°. After the rainwater is blocked by the first waterproof part 201, the rainwater will drip onto the side wall 104. Since the angle between the side wall 104 and the plane where the air outlet 103 is located is less than 90°, the rainwater dripping into the accommodating space 101 will be discharged.

[0042] In an optional embodiment, combined with Figure 3 and Figure 4 As shown, the first waterproof part 201 includes a first support member 2011 and a plurality of first water-blocking plates 2012. The first support member 2011 has a plurality of first through holes 2013. The first water-blocking plates 2012 and the first through holes 2013 are arranged in a one-to-one correspondence, that is, the first water-blocking plates 2012 are arranged in an array on the first support member 2011. The first water-blocking plates 2012 and the first through holes 2013 are arranged in a corresponding manner. The first support member 2011 has a plurality of first through holes 2013. Each first through hole 2013 is correspondingly matched with a first water-blocking plate 2012. Hot air inside the equipment 50 can be discharged through the first through holes 2013 on the first support member 2011, thereby ensuring the ventilation performance of the protective equipment 50.

[0043] Because a first through hole 2013 is formed in the first support member 2011, rainwater may enter the device 50 through the first through hole 2013. Therefore, a first water-blocking plate 2012 is provided on the first support member 2011. One end of the first water-blocking plate 2012 is connected to the side of the first support member 2011 near the air outlet 103, and the other end of the first water-blocking plate 2012 is spaced apart from the first through hole 2013. The first water-blocking plate 2012 covers the first through hole 2013 along a direction perpendicular to the plane of the first support member 2011. Specifically, as shown... Figure 3 As shown, Figure 3 The direction of the middle arrow is perpendicular to the plane of the first support member 2011, which is also the axial direction of the opening of the first through hole 2013. The first water-blocking plate 2012 is correspondingly arranged with the first through hole 2013, and there is a gap between the first water-blocking plate 2012 and the first through hole 2013. This ensures the ventilation performance of the first waterproof part 201 and prevents rainwater from entering the device 50 through the first through hole 2013. The other end of the first water-blocking plate 2012 is parallel to the plane of the first support member 2011. The first water-blocking plate 2012 is located on the end face of the first support member 2011 near the air outlet 103, thereby blocking rainwater and preventing rainwater from entering the interior of the housing 10.

[0044] In this embodiment, multiple first water-blocking plates 2012 can be provided, so that when the first water-blocking plates 2012 are installed on the first support member 2011, they can be fixed to the first support member 2011 in an array sequentially. Generally speaking, the device 50 is usually installed in the external environment, and the device 50 requires small ventilation openings. Therefore, the number of first water-blocking plates 2012 and first through holes 2013 can be 3, 4, etc., which can be specifically set according to the size of the protective device 50. This application does not make specific limitations here.

[0045] In an optional embodiment, the two opposite sides of the first through hole 2013 are bent away from the first water-blocking plate 2012 to form a first baffle 2014, and the distance between the two first baffles 2014 gradually decreases along the opening axis of the first through hole 2013. Specifically, a plurality of first through holes 2013 are provided on the first support member 2011, and the first baffle 2014 is provided at the edge of the first through hole 2013. The first baffle 2014 is provided on the end face of the first support member 2011 away from the first water-blocking plate 2012, thereby blocking rainwater. The first baffle 2014 is provided on the two sides of the first through hole 2013 parallel to the plane of the air outlet 103, that is, the position where the first baffle 2014 is connected to the first support member 2011 is parallel to the plane of the air outlet 103. On the one hand, it allows hot air inside the device 50 to escape through the first through hole 2013, preventing the first baffle 2014 from blocking the escape of hot air from the device 50. On the other hand, the first baffle 2014 can cooperate with the first water-blocking plate 2012 to prevent rainwater from entering the device 50. The two first baffles 2014, which are set at the edge of the first through hole 2013, have a gradually decreasing distance between them along the opening axis of the first through hole 2013, which can effectively reduce the amount of rainwater entering the device 50 through the first through hole 2013.

[0046] In an optional embodiment, combined with Figure 5 and Figure 6 As shown, the second waterproof part 202 includes a second support member 2021 and a plurality of second water-blocking plates 2022. The second support member 2021 has a plurality of second through holes 2023, and the second water-blocking plates 2022 are arranged in a one-to-one correspondence with the second through holes 2023. Specifically, the second water-blocking plates 2022 are arranged in an array on the second support member 2021, with each second water-blocking plate 2022 corresponding to a second through hole 2023. One end of each second water-blocking plate 2022 is connected to the side of the second support member 2021 away from the air inlet 102, and the other end of each second water-blocking plate 2022 is spaced apart from the second through holes 2023. The second water-blocking plates 2022 cover the second through holes 2023 along a direction perpendicular to the plane of the second support member 2021. Specifically, as shown... Figure 5 As shown, Figure 5The direction of the arrow is perpendicular to the plane of the second support member 2021, which is also the axial direction of the opening of the second through hole 2023. The second support member 2021 has several second through holes 2023, which allow hot air inside the device 50 to escape. A second water-blocking plate 2022 is provided at the edge of each of the second through holes 2023. The second water-blocking plate 2022 is located on the end face of the second support member 2021 away from the air inlet 102. When rainwater enters the accommodating space 101, the second water-blocking plate 2022 can block the rainwater, preventing it from entering the device 50. Specifically, some rainwater passes through the first waterproof part 201 and enters the accommodating space 101, causing splashing. The second water-blocking plate 2022 can block the splashed rainwater, preventing it from entering the device 50 and damaging the components inside. In this embodiment, the second water-blocking plate 2022 is disposed on the end face of the second support member 2021 away from the air inlet 102, and the second water-blocking plate 2022 is parallel to the plane of the second support member 2021. Thus, after rainwater enters the accommodating space 101, the rainwater will hit the inner wall 104 of the housing 10, causing splashing. The splashed rainwater will be blocked by the second water-blocking plate 2022, thereby preventing rainwater from entering the device 50 through the second through hole 2023. The second through hole 2023 on the second support member 2021 allows hot air inside the device 50 to enter through the second through hole 2023.

[0047] In an optional embodiment, a first through hole 2013 and a second through hole 2023 are formed on the first support member 2011, allowing hot air inside the device 50 to be discharged through the second through hole 2023 and the first through hole 2013. A first water-blocking plate 2012 corresponding to the first through hole 2013 is provided on the first support member 2011 to block rainwater, thereby preventing rainwater from entering the device 50 through the first through hole 2013. A second water-blocking plate 2022 corresponding to the second through hole 2023 is provided on the second support member 2021 to further block rainwater, preventing splashed rainwater from entering the device 50 through the second through hole 2023. A plurality of second baffles 2024 are provided on the second support member 2021, located at the edge of the second through hole 2023 near the first waterproof part 201. The second baffle 2024 is disposed on the end face of the second support member 2021 away from the second water-blocking plate 2022, that is, the second baffle 2024 is disposed near the air inlet 102. The second baffle 2024 is disposed at the edge of the second through hole 2023 near the first waterproof part 201, thereby allowing hot air inside the device 50 to be discharged from the second through hole 2023. In this embodiment, the first baffle 2014 is disposed at the edge of the first through hole 2013 parallel to the plane of the exhaust port, and the second baffle 2024 is disposed at the edge of the second through hole 2023 near the first anti-water part. The first baffle 2014 and the second baffle 2024 can further block rainwater, thereby ensuring the waterproof performance of the protective device.

[0048] In an optional embodiment, a water-blocking strip 2025 is provided at the end of the second support member 2021 near the first waterproof part 201, and the water-blocking strip 2025 extends away from the air inlet 102. The water-blocking strip 2025 can block the end face of the second water-blocking plate 2022 near the first waterproof part 201, so that after rainwater enters the accommodating space 101, the water-blocking strip 2025 can block the rainwater, thereby preventing splashed rainwater from entering the device 50 through the second water-blocking plate 2022. The water-blocking strip 2025 is perpendicular to the plane of the second support member 2021, that is, the water-blocking strip 2025 extends along the axial direction of the plane of the second support member 2021, and its end exceeds the height of the second water-blocking plate 2022, thereby preventing rainwater from hitting the second water-blocking plate 2022 and entering the device 50 through the second through hole 2023.

[0049] In an optional embodiment, such as Figure 7As shown, a protective component 30 is provided on the housing 10 and is located on the air outlet 103. The protective component 30 includes a bracket 301 and a protective net 302. The bracket 301 is detachably connected to the housing 10, and the protective net 302 is located inside the bracket 301. The protective component 30 on the air outlet 103 can block external debris and other contaminants from entering the accommodating space 101, thereby preventing the exhaust of hot air from the device 50. The protective component 30 includes a bracket 301 and a protective net 302. The bracket 301 and the protective net 302 are detachably connected. When installing the protective component 30 on the housing 10, the protective net 302 can be fixed to the bracket 301 first, and then the protective component 30 can be fixed to the air outlet 103 of the housing 10, thereby protecting the housing 10. In this embodiment, the protective net 302 can be a wire mesh; this application does not specifically limit its use.

[0050] In an optional embodiment, combined with Figure 8 and Figure 9 As shown, the protective device also includes a fan assembly 40, which is disposed at the air inlet 102 of the housing 10, and the exhaust port of the fan assembly 40 is connected to the accommodating space 101. When the fan assembly 40 is disposed on the housing 10, protective cotton (not shown) can be provided at the edge of the air inlet 102 of the housing 10 to seal the connection between the fan assembly 40 and the housing 10, thereby enabling the hot air to be quickly discharged through the air inlet 102 and the exhaust port 103. In this embodiment, when the fan assembly 40 and the housing 10 are disposed inside the device 50, the fan assembly 40 can be activated to draw hot air from inside the device 50, which is then transferred to the accommodating space 101 through the air inlet 102 and discharged through the exhaust port 103. In this embodiment, multiple holes can be opened on the device 50 so that when the fan assembly 40 draws air from the device 50, outside air can be drawn into the device 50 through the multiple holes, thereby preventing the device 50 from being drawn into a vacuum. Specifically, this application does not make any specific limitations.

[0051] In a specific application scenario, when the protective device is installed inside the equipment 50, the fan assembly 40 is activated to draw in hot air from inside the equipment 50 and discharge it through the gap between the first through hole 2013 and the second through hole 2023, and between the first waterproof part 201 and the second waterproof part 202. On rainy days, since the equipment 50 is placed outdoors, rainwater will pass through the protective net 302 and enter the accommodating space 101. The first waterproof part 201 can block the rainwater; specifically, the first water-blocking plate 2012 can block the rainwater, thereby preventing rainwater from entering the equipment 50 through the first through hole 2013. Some rainwater that passes through the first water-blocking plate 2012 can be further blocked by the first baffle 2014. Furthermore, regardless of whether rainwater hits the side wall 104 opposite to the air inlet 102, the rainwater will splash. The second waterproof part 202 can block the splashed rainwater. Specifically, after the rainwater splashes on the side wall 104 of the housing 10, the second water-blocking plate 2022 and the water-blocking strip 2025 can block the rainwater, thereby preventing rainwater from entering the device 50 through the second through hole 2023. If some rainwater passes through the second through hole 2023, the second baffle 2024 can further block the rainwater. Through the cooperation of the first waterproof part 201 and the second waterproof part 202, rainwater can be effectively prevented from entering the device 50, so that the protective device achieves the expected waterproof effect. The protective device can be installed in an outdoor charging pile to improve the heat dissipation and waterproof performance of the charging pile. It can also be installed in other outdoor electronic devices, which are not specifically limited here.

[0052] By employing the above-described method, this application, through the provision of an air inlet 102 and an air outlet 103 on the housing 10, and the staggered arrangement of a first waterproof portion 201 and a second waterproof portion 202 on the inner sidewall 104 of the housing 10, achieves multiple barriers against rainwater. This effectively improves the waterproof performance of the protective device 50 while reducing its volume. By placing the first waterproof portion 201 on the sidewall 104 at the upper edge of the air outlet 103, with an angle of less than 90° between it and the plane of the air outlet 103, it effectively blocks external rainwater. Furthermore, by ensuring that the projections of the first waterproof portion 201 and the second waterproof portion 202 on the plane of the air inlet 102 completely cover the air inlet 102, it prevents rainwater from entering the device 50 through the air inlet 102. By installing a first water-blocking plate 2012 on the first support member 2011 and opening a first through hole 2013 on the first support member 2011, ventilation can be achieved while rainwater is blocked by the first water-blocking plate 2012. By installing a first baffle 2014 on the first support member 2011, rainwater passing through the first through hole 2013 can be further blocked. By installing a protective member 30 on the housing 10, external debris can be blocked, thereby preventing debris from entering the accommodating space 101 and affecting the ventilation effect of the protective device. By installing a fan assembly 40 inside the protective device, the heat dissipation effect of the equipment 50 can be effectively improved.
