The filter part is detachably mounted on the shell assembly and at least partially extends out of the top of the shell assembly. The protective cover is sleeved on the outside of the filter part and forms a sandwich cavity for air flow with at least part of the filter part. The sandwich cavity forms an air inlet channel with the filter part and the drying part to communicate with the interior of the accommodating cavity, wherein the drying part is located on the inner side of the shell assembly and is arranged in abutment with the top of the shell assembly, and the orthographic projection of the drying part along the height direction of the shell assembly covers the filter part.

[0005] In some embodiments, the filter portion includes a protrusion extending out of the shell assembly, and the distance between the top of the protective cover and the top of the protrusion accounts for at least 1 / 4 of the width of the protrusion along its height direction to form a part of the cavity, and the protective cover is circumferentially spaced from the protrusion of the filter portion to form another part of the cavity.

[0006] In some embodiments, the filter portion is threadedly engaged with the top of the housing assembly to adjust the size of the protrusion along its own height direction.

[0007] In some embodiments, the drying section is opposite to the filtering section and both are arranged in an annular shape, and the radial dimension of the drying section is at least 1.5 times the radial dimension of the filtering section, so that the flow rate of the airflow entering the drying section is reduced under the action of negative pressure.

[0008] In some embodiments, the shell assembly includes an upper shell and a lower shell fixed to each other, and the exhaust part includes an exhaust fan arranged inside the lower shell, the exhaust fan is connected to a duct, the first end of the duct extends to the outside of the lower shell, and the second end extends to the inside of the accommodating cavity, and the duct is provided with an electromagnetic valve for adjusting its own opening.

[0009] In some embodiments, the filter portion includes a first positioning cylinder that is limitedly installed on the top of the upper shell body, a first ring is installed on the top of the first positioning cylinder, a positioning ring is threadedly connected to the outer peripheral surface of the first ring, and a filter net is limitedly connected to the inner side of the positioning ring to filter the gas flowing in the air intake channel.

[0010] In some embodiments, the first positioning tube is a square structure, and a connecting piece is installed on the outer side thereof, and the first positioning tube is detachably connected to the protective cover through the connecting piece.

[0011] In some embodiments, the connecting member includes a first connecting frame that is sleeved and fixed on the outside of the first positioning tube, a second connecting frame stacked with the first connecting frame, and an assembly part, at least part of the outer circumferential surface of the assembly part has a threaded portion, and the first connecting frame and the second connecting frame are locked by the threaded portion, and the second connecting frame is connected to the protective cover through a support rod.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0026] The present application embodiment provides a fiber optic switching box for communication engineering. Figure 1-Figure 5 The optical fiber switching box for communication engineering in the embodiment of the present application is described in detail.

[0027] like Figure 1 As shown, the embodiment of the present application provides an optical fiber exchange box for communication engineering, the optical fiber exchange box includes a housing component 1, a circulating heat exchange component and a protective cover 8, the internal structure of the housing component 1 has a cavity 2 for placing network communication equipment and optical fiber connectors, the circulating heat exchange component includes an exhaust component 3 and an air inlet component 4, please refer to Figure 4 The air inlet member 4 is arranged at the top of the shell assembly 1. It can be understood that in order to ensure that the airflow can enter the interior of the shell assembly 1 from the air inlet member 4, the air inlet member 4 serves as a channel connecting the inside and outside of the shell assembly 1, and there is a risk of water ingress. Based on this, the air inlet member 4 can be protected by setting a protective cover 8.

[0028] Specifically, the exhaust piece 3 is arranged inside the shell assembly 1, and the exhaust piece 3 can create negative pressure inside the shell assembly 1. It can be understood that the network communication equipment inside the shell assembly 1 will generate high temperature during operation. Starting the exhaust piece 3 can discharge the high-temperature gas inside the shell assembly 1 to form a negative pressure environment inside the shell assembly 1. Under the action of this negative pressure environment, the normal temperature gas or low temperature gas outside the shell assembly 1 can enter the interior of the shell assembly 1 through the air inlet piece 4, thereby balancing the temperature inside the shell assembly 1.

[0029] like Figure 3 As shown, the air inlet 4 includes a filter 5 and a drying part 6. The filter 5 is detachably mounted on the housing assembly 1 and at least partially extends out of the top of the housing assembly 1. It is understandable that the airflow outside the housing assembly 1 passes through the filter 5 and the drying part 6 under the negative pressure. It is understandable that the filter 5 can filter the airflow passing through it, thereby preventing the airflow from carrying impurities and adhering to the surface of the network communication device, and the drying part 6 can dry the airflow passing through it, thereby preventing the airflow from carrying too much moisture into the housing assembly 1. In addition, since the filter 5 is detachably connected to the housing assembly, the operator can flexibly replace the filter 5.

[0030] The protective cover 8 is sleeved on the outside of the filter part 5, and forms a cavity A for air flow with at least part of the filter part 5. The cavity A forms an air inlet passage with the filter part 5 and the drying part 6 to communicate with the inside of the accommodating cavity 2. It can be understood that the inner cavity space of the protective cover 8 is larger than the size of the filter part 5. The protective cover 8 protects the filter part 5 while also leaving the cavity A for air flow to pass through. The drying part 6 is located on the inner side of the shell assembly 1 and is arranged in contact with the top of the shell assembly 1. The orthographic projection of the drying part 6 along the height direction of the shell assembly 1 covers the filter part 5. Based on this, the air flow passing through the filter part 5 can completely enter the drying part 6.

[0031] In some embodiments, please refer to Figure 2 and Figure 3 The filter portion 5 includes a protruding portion extending out of the shell assembly 1, and the distance between the top of the protective cover 8 and the top of the protruding portion occupies at least 1 / 4 of the width of the protruding portion along its height direction to form a portion of the clamping cavity A, and the protective cover 8 is arranged at intervals with the protruding portion of the filter portion 5 along the circumferential direction to form another portion of the clamping cavity A.

[0032] It can be understood that since the airflow from the outside of the shell assembly 1 through the clamping cavity A into the filter part 5 and the drying part 6 is subjected to negative pressure, in order to ensure that the airflow can flow smoothly and without obstacles, a certain distance can be left between the top of the protective cover 8 and the top of the protrusion to provide space for the airflow to circulate and stay.

[0033] In some embodiments, the filter portion 5 is threadedly engaged with the top of the housing assembly 1 to adjust the size of the protrusion along its own height direction.

[0034] It is understandable that the filtering of the airflow by the filter part 5 is achieved based on the filtering material inside it. As time goes by, the filtering effect of the filter part 5 will gradually decay. Based on this, the filter part 5 is designed to be threadedly engaged with the shell assembly 1, the width of the protrusion can be adjusted, and the entire filter part 5 can also be removed from the shell assembly 1 and replaced.

[0035] In some embodiments, the drying section 6 is opposite to the filtering section 5 and both are arranged in an annular shape, and the radial dimension of the drying section 6 is at least 1.5 times the radial dimension of the filtering section 5 so that the flow rate of the airflow entering the drying section 6 is reduced under the action of negative pressure.

[0036] It can be understood that the drying section 6 is adjacent to the filtering section 5 and is located downstream of the filtering section 5. Since the radial dimension of the drying section 6 is larger than the radial dimension of the filtering section 5, the flow rate of the airflow will be reduced after entering the drying section 6 with a larger inner diameter from the filtering section 5 with a smaller inner diameter, thereby ensuring that the airflow can be fully mixed and contacted with the drying section 6 to ensure the drying effect of the airflow.

[0037] In some embodiments, please refer to Figure 3 The shell assembly 1 includes an upper shell 11 and a lower shell 12 fixed to each other. The exhaust member 3 includes an exhaust fan 31 arranged inside the lower shell 12. The exhaust fan 31 is connected to a duct 32. The first end of the duct 32 extends to the outside of the lower shell 12, and the second end extends to the inside of the accommodating cavity 2. The duct 32 is provided with a solenoid valve 7 for adjusting its own opening.

[0038] It is understandable that when the temperature inside the shell assembly 1 rises, the exhaust fan 31 can be turned on to discharge the high-temperature gas from the shell assembly 1. In addition, the solenoid valve 7 can prevent the gas outside the shell assembly 1 from entering the shell assembly 1 through the conduit 32.

[0039] In some embodiments, please refer to Figure 4 and Figure 5 The filter unit 5 includes a first positioning cylinder 51 which is limitedly installed on the top of the upper shell 11. A first sleeve 52 is installed on the top of the first positioning cylinder 51. A positioning ring 53 is threadedly connected to the outer peripheral surface of the first sleeve 52. A filter screen 54 is limitedly connected to the inner side of the positioning ring 53 to filter the gas flowing in the air intake channel. The first positioning cylinder 51 is a square structure, and a connecting piece 55 is limitedly installed on the outer side thereof. The first positioning cylinder 51 is detachably connected to the protective cover 8 through the connecting piece 55.

[0040] It is understandable that the filter screen 54 is installed on the inner side of the positioning ring 53, and the positioning ring 53 is threadedly connected to the first sleeve ring 52. Based on this, the positioning ring 53 can be assembled or disassembled on the first sleeve ring 52. In addition, the protective cover 8 can be detachably connected to the first positioning cylinder 51, so that the protective cover 8 can be disassembled and replaced.

[0041] In some embodiments, Figure 4 As shown, the connecting member 55 includes a first connecting frame 551 which is sleeved and fixed on the outside of the first positioning tube 51, a second connecting frame 552 stacked with the first connecting frame 551, and an assembly part 553. At least part of the outer peripheral surface of the assembly part 553 has a threaded portion, and the first connecting frame 551 and the second connecting frame 552 are locked by the threaded portion. The second connecting frame 552 is connected to the protective cover 8 by a support rod 554.

[0042] In the embodiment of the present application, the protective cover 8 is fixed on the first positioning tube 51 by the support rod 554 and the second connecting frame 552. It can be understood that the support rod 554 is a linear structure, and the airflow on the outside of the protective cover 8 can penetrate into the clamping cavity A from both sides of the support rod 554 under the action of negative pressure.

[0043] In some embodiments, please refer to Figure 3 The drying section 6 includes a second positioning cylinder 61 which is limitedly installed on the inner wall of the upper shell 11. The second positioning cylinder 61 and the first positioning cylinder 51 are arranged correspondingly so that the insides of the two are connected and form at least part of the air inlet passage. A breathable net 62 is arranged at the bottom of the second positioning cylinder 61 so that the air inlet passage is connected with the accommodating cavity 2. The interior of the second positioning cylinder 61 is filled with a drying element 63, which is stacked and abuts against one side of the breathable net 62. The drying section 6 also includes a second sleeve ring 64, the top of which is limitedly connected to the inner wall of the upper shell 11, the outer peripheral surface of the second positioning cylinder 61 can be threadedly connected to the inner peripheral surface of the second sleeve ring 64, and the drying element 63 is laid in the interior of the second positioning cylinder 61 in a continuous layered form and includes a desiccant.

[0044] It is understandable that the airflow is dried by the desiccant during the process of passing through the drying section 6, and the airflow passing through the drying element 63 can continue to pass through the air-permeable net 62 and enter the interior of the upper shell 11. In addition, since the second positioning cylinder 61 is threadedly connected to the second sleeve 64, the second positioning cylinder 61 can be taken out from the interior of the upper shell 11, and then the drying element 63 can be replaced.
