In the first position, the sealing member seals the heat dissipation hole. In the second position, the seal is far from the hot hole so that the receiving cavity communicates with the outside.

The light traffic case that this application provided includes: a housing and a seal. Wherein the housing is formed with a receiving cavity for receiving the communication device, such that the communication device can be placed in the receiving cavity. And the shell is provided with a heat dissipation hole communicated with the accommodating cavity. The heat dissipation holes can enable air in the accommodating cavity to circulate with external air so as to dissipate heat of the communication equipment.

In addition, the sealing element is movably connected with the shell, and the sealing element has a first position and a second position in the moving process. The user may move the seal to transition the seal between the first position and the second position.

When the air humidity outside the light traffic box is high, a user can move the sealing piece to enable the sealing piece to be switched to the first position to seal the heat dissipation holes, so that the outside moist air is prevented from entering the light traffic box through the heat dissipation holes. The moist air can not form dew when being cooled in the light traffic box. Therefore, the dew can be easily formed in the interior of the light cross box by humid air, and the dew drops on the communication equipment, so that the technical problem that the communication equipment cannot normally run is easily solved.

When the air temperature and the air humidity outside the light box are proper, the user can move the sealing member to enable the sealing member to be located at the second position so as to enable the containing cavity to be communicated with the outside.

This application can strengthen the leakproofness of sealing member to the louvre through increasing the inseparable degree of sealing member and storage tank laminating (cooperation), guarantees the leakproofness of sealing member to the louvre more easily like this. In addition, the outer wall surface of the shell can be kept flat, so that the aesthetic property of the shell can be enhanced.

In one possible implementation, the light box further comprises an engaging assembly comprising a first engaging member and/or a second engaging member. The first suction piece is connected with the shell, and the sealing piece is attached to the first suction piece under the condition of the first position.

The support bar is in the third position with the seal in the second position and is coupled to the seal to stabilize the seal in the second position. The support bar is in a fourth position with the seal in the first position such that the seal is movable from the second position to the first position.

In the case of the second position of the seal, the support bar is in the third position and is connected to the seal to stabilize the seal in the second position, so that the user can be prevented from applying a force to the seal to stabilize it in the second position. Thus, a part of manpower can be saved.

Acquiring a first air temperature, a second air temperature and air humidity, wherein the first air temperature is the air temperature outside the shell, and the second air temperature is the air temperature in the accommodating cavity; when the air humidity is greater than or equal to the preset humidity and the difference between the first air temperature and the second air temperature is greater than or equal to the preset difference, the driver is controlled to act, so that the supporting rod moves to a fourth position, and the sealing element can move from the second position to the first position; when the air humidity is smaller than the preset humidity and the difference between the first air temperature and the second air temperature is smaller than the preset difference, the driver is controlled to act, so that the supporting rod moves to the third position, and the sealing element can be stabilized at the second position.

When the air humidity is greater than or equal to the preset humidity and the difference between the first air temperature and the second air temperature is greater than or equal to the preset difference, the controller controls the driver to act, so that the supporting rod moves to the fourth position, and the sealing element can move from the second position to the first position. It can be understood that the outside air humidity of light cross box is great this moment, and the outside temperature of casing is great with the temperature difference in holding the chamber, and the sealing member can move to the first position to shutoff louvre, can avoid outside moist air to get into light cross box inside by the louvre like this, meet condensation and tie dew, dew drops to communication equipment on, lead to communication equipment unable normal work.

The light cross box is also called an optical cable cross box or a street cabinet and is generally arranged on a main optical cable. The optical cross box is used for dividing most optical cables into a plurality of small-pair optical cables in different directions after passing through optical splitters in the optical cross box, so that the utilization efficiency of main optical fibers is improved, the number of pairs of the main optical fibers is reduced, and the optical cross box is a dividing point of a feeder optical cable and a distribution optical cable. In short, the optical cross box can be used for connection, distribution and dispatch of a trunk optical cable and a distribution optical cable in a communication network for a communication system, an electric power system, a traffic control system and a cable television system.

The existing light cross box is generally provided with a radiating hole for ventilation and heat radiation, but when the air humidity outside the light cross box is large, outside moist air easily enters the inside of the light cross box through the radiating hole. If the temperature in the light traffic box is low (for example, at night, when the temperature is low or when the temperature in the light traffic box is smaller than the temperature outside the light traffic box), dew is easily formed on the inner wall of the light traffic box by moist air, and drops onto the communication equipment, so that the communication equipment is likely to fail to operate normally.

To address such issues, embodiments of the present application provide a light cross box 1000 that is resistant to condensation.

Fig. 1 shows one of schematic structural diagrams of an optical cross box 1000 according to an embodiment of the present application. As shown in fig. 1, the light box 1000 mainly includes: a housing 10 and a seal 20.

Fig. 2 shows an internal structure of a light box 1000 according to an embodiment of the present application. As shown in fig. 2, the housing 10 is formed with a housing chamber 11 for housing the communication device, and a heat radiation hole 12 communicating with the housing chamber 11 is formed in the housing 10.

Optionally, a plurality of heat dissipation holes 12 may be provided on the housing 10. This can improve the heat dissipation efficiency of the communication device.

As an example, continuing with fig. 2, the housing 10 is provided with two heat dissipation holes 12, and the two heat dissipation holes 12 are located on opposite sides of the housing 10.

Continuing with fig. 2, the seal 20 is movably coupled to the housing 10. The seal 20 has a first position and a second position during movement. In the first position, the seal 20 closes off the heat dissipation aperture 12. In the second position, the seal 20 diverges away from the thermal aperture 12 to place the receiving chamber 11 in communication with the outside.

As an example, continuing to refer to fig. 2, the seal 20 may be a cover plate (lid). With the seal 20 in the first position, the cover plate may close the heat dissipation holes 12. With the seal 20 in the second position, continuing as shown in fig. 2, the cover plate diverges away from the thermal aperture 12 to place the receiving chamber 11 in communication with the outside.

It will be appreciated that the number of seals 20 may correspond to the number of heat dissipating holes 12 described above. As further shown in fig. 2, the number of seals 20 may be two, and the two seals 20 may be located on opposite sides of the housing 10.

The seal 20 may also be a plug, for example. With the seal 20 in the first position, the plug may plug the louvre 12 to close off the louvre 12. With the seal 20 in the second position, the plug is far from the discrete thermal aperture 12 to place the containment chamber 11 in communication with the outside. Of course, the sealing member 20 may be other sealing members, which are not limited in this embodiment.

Thus, the light traffic box 1000 provided by the present application includes: a housing 10 and a seal 20. Wherein the housing 10 is formed with a receiving chamber 11 for receiving the communication device, such that the communication device can be placed in the receiving chamber 11. The housing 10 is provided with a heat radiation hole 12 communicating with the accommodation chamber 11. The heat dissipation holes 12 allow air in the accommodating chamber 11 to circulate with external air to dissipate heat of the communication device.

In addition, the seal 20 is movably connected to the housing 10, the seal 20 having a first position and a second position during movement. The user may move the seal 20 to transition the seal 20 between the first position and the second position.

When the humidity of the air outside the light box 1000 is high, the user can move the sealing member 20 to enable the sealing member 20 to be switched to the first position, and the heat dissipation holes 12 are blocked, so that the outside moist air is prevented from entering the light box 1000 through the heat dissipation holes 12. The moist air will not cool to form dew within the light box 1000. Therefore, the embodiment of the application can solve the technical problems that dew is easy to form in the light traffic box 1000 by humid air, and the dew drops on the communication equipment, so that the communication equipment is easy to fail to operate normally.

When the air temperature and the air humidity are low outside the light box 1000, the user can move the sealing member 20 to place the sealing member 20 at the second position so that the accommodating chamber 11 communicates with the outside. In this way, the air in the housing chamber 11 and the air from the outside can circulate through the heat dissipation holes 12 to dissipate heat from the communication device.

In this way, the user moves the seal 20 to switch between the first and second positions. According to the embodiment of the application, the purposes of preventing dew from forming in the optical cross box 1000 and ventilating and radiating for communication equipment can be achieved, so that the safety and stability of the operation of the communication equipment can be improved.

In some embodiments, as further shown in fig. 2, the seal 20 may be located on the outside of the housing 10. This may be convenient for operating the seal 20 to switch between the first and second positions.

In the case where the seal 20 is located inside the housing 10, it is inconvenient for a user to operate the seal 20, and the seal 20 is not easily switched between the first position and the second position. The seal 20 of the embodiment of the present application is located outside the housing 10, so that a user can conveniently operate the seal 20, and the seal 20 is easy to switch between the first position and the second position.

Also, if the sealing member 20 is disposed on the inner side of the housing 10, dew may be formed in the heat dissipation hole 12 by the outside humid air in the case that the sealing member 20 is disposed at the first position, and the dew in the heat dissipation hole 12 may flow into the communication device in the case that the sealing member 20 is shifted to the second position, so that the communication device may not operate normally, and the sealing member 20 is disposed on the outer side of the housing 10 may solve this problem.

In other embodiments, the seal 20 may also be located inside the housing 10, which is not limited in this embodiment.

In some embodiments, as further shown in FIG. 2, the upper end of the seal 20 may be rotatably coupled to the housing 10. This may facilitate a user rotating the seal 20 to transition the seal 20 between the first and second positions.

In addition to this, in the case where the seal 20 is located at the first position, dew may be formed on the outer wall surface of the housing 10 and the outside of the seal 20 by the outside humid air, and in the case where the seal 20 is shifted to the second position, the outside of the seal 20 may be inclined.

This facilitates the flow of dew from the outer wall surface of the casing 10 above the sealing member 20 to the bottom outside the casing 10 along the outside of the sealing member 20, and also facilitates the flow of dew from the sealing member 20 to the bottom outside the casing 10 along the outside of the sealing member 20, thereby preventing such dew from flowing to the inside of the casing 10.

For example, other portions (side ends, bottom ends, or middle portions, etc.) of the seal member 20 may be rotatably connected to the housing 10, which is not limited in the embodiment of the present application.

Illustratively, the light box 1000 may further include: and one end of the hinge is connected with the shell 10, and the other end of the hinge is connected with the sealing element 20, so that the sealing element 20 is rotationally connected with the shell 10.

In other embodiments, the seal 20 may not be directly connected to the housing 10, but may be connected to the housing 10 via an adapter. The adapter may translate the seal 20 between the first and second positions in a translational manner. For convenience of description, the adaptor is not described herein for a moment in the embodiments of the present application, and reference may be made to the following description.

Fig. 3 shows an enlarged view at a in fig. 2. In some embodiments, as shown in fig. 3, the housing 10 is provided with a receiving groove 13 on the outer side, and the heat dissipation hole 12 is formed on the bottom wall surface of the receiving groove 13. In the first position, the seal 20 is located in the receiving groove 13.

This application embodiment is equipped with accommodation groove 13 in the outside of casing 10, under the condition that sealing member 20 is located the first position, sealing member 20 is located accommodation groove 13, compare in not setting up accommodation groove 13, come shutoff louvre 12 with the wall laminating of louvre 12 department on sealing member 20 and casing 10 (sealing member 20 still has the gap with the wall of louvre 12 department on casing 10, so the leakproofness is relatively poor), this application embodiment can strengthen sealing member 20 to the leakproofness of louvre 12 through increasing sealing member 20 and accommodation groove 13 laminating (the degree of fit) degree, guarantee sealing member 20 to the leakproofness of louvre 12 more easily like this. In addition, the outer wall surface of the case 10 can be kept flat, so that the aesthetic appearance of the case 10 can be enhanced.

In some embodiments, the light box 1000 further includes a pull-in assembly that includes the first pull-in member 30 and/or the second pull-in member. Wherein, the first engaging member 30 is connected with the housing 10, and in the first position, the sealing member 20 is attached to the first engaging member 30. Alternatively, the second engaging member is connected to the seal member 20, and the seal member 20 is attached to the housing 10 when in the first position. Alternatively, the first engaging member 30 is connected to the housing 10, the second engaging member is connected to the seal member 20, and the first engaging member 30 is bonded to the second engaging member when the seal member 20 is in the first position.

In this way, the sealing member 20 can be tightly attached to the housing 10, so that the sealing performance of the sealing member 20 to the heat dissipation holes 12 is enhanced.

In one possible implementation, continuing to refer to fig. 3, the first engaging member 30 may be coupled to the housing 10, and in the first position, the seal member 20 may be engaged with the first engaging member 30.

By way of example, the first engaging member 30 may be a magnetic object (e.g., a magnet, etc.), and the seal member 20 may contain a ferromagnetic substance (e.g., iron, cobalt, nickel, etc.). In the case of the first position, the first engaging member 30 may attract the sealing member 20 to make the sealing member 20 closely fit with the housing 10 at the heat dissipation hole 12, so that the sealing property of the sealing member 20 to the heat dissipation hole 12 may be enhanced.

The first engaging member 30 may also be a suction cup, for example. In the first position, the suction cup may suction the seal 20 to engage the seal 20 with the first engaging member 30. Because the suction cup has the characteristic of strong suction force, the tightness of the fitting of the sealing element 20 with the shell 10 (the shell 10 at the radiating hole 12) can be enhanced, so that the tightness of the sealing element 20 is enhanced.

As an example, as further shown in fig. 3, the first engaging member 30 may be disposed on a wall surface of the accommodating groove 13 where the heat dissipation holes 12 are not formed. The first engaging member 30 may be connected to the inner wall surface of the accommodating groove 13 by an adhesive connection.

In another possible implementation, the second engaging member may be coupled to the sealing member 20, and the sealing member 20 may be engaged with the housing 10 when in the first position. This allows the seal 20 to conform more closely to the housing 10 at the heat sink 12, thereby enhancing the seal 20 sealing to the heat sink 12.

The second engaging member may refer to the description of the first engaging member 30, which is not repeated in the embodiments of the present application.

In yet another possible implementation, the first engaging member 30 may be coupled to the housing 10 and the second engaging member may be coupled to the seal member 20, and with the seal member 20 in the first position, the first engaging member 30 may be coupled to the second engaging member. In this way, the degree of tightness of the fitting of the seal 20 to the housing 10 at the heat dissipation hole 12 can also be enhanced, thereby enhancing the tightness of the seal 20 to the heat dissipation hole 12.

It should be noted that, when the first engaging member 30 and the second engaging member are both magnetic objects (such as magnets), the magnetic poles of the first engaging member 30 and the magnetic poles of the second engaging member should be opposite.

In some embodiments, as further shown in fig. 2, the light box 1000 further includes a support bar 40, the support bar 40 being connected to the housing 10. The support bar 40 is movable between a third position and a fourth position. With the seal 20 in the second position, the support rod 40 is in the third position and is coupled to the seal 20 to stabilize the seal 20 in the second position. With the seal 20 in the first position, the support bar 40 is in the fourth position so that the seal 20 can be moved from the second position to the first position.

With the seal 20 in the second position, the support rod 40 is in the third position and is coupled to the seal 20 to stabilize the seal 20 in the second position, thereby avoiding the user from applying a force to the seal 20 to stabilize it in the second position. Thus, a part of manpower can be saved.

With the seal 20 in the first position, the support bar 40 in the fourth position, the transition of the seal 20 to the first position is avoided, so that the seal 20 can be moved from the second position to the first position.

In one possible implementation, the seal 20 is rotationally coupled to the housing 10 at one end thereof.

Alternatively, one end of the support rod 40 may be hinged with the housing 10, and the other end of the support rod 40 may be slidably coupled with the sealing member 20. For example, the seal 20 is provided with a chute that includes a first end (which may be the end of the chute that is distal from the connection of the seal 20 to the housing 10) and a second end (which may be the end of the chute that is proximal to the connection of the seal 20 to the housing 10). The other end of the support bar 40 is provided with a protrusion which can be engaged with the chute. With the projection slid to the first end, the support bar 40 is in the third position and the seal 20 is in the second position. With the projection slid to the second end, the support bar 40 is in the fourth position and the seal 20 is in the first position.

In the case where the projection is slid to the first end, the support bar 40 is positioned at the third position, and the other end of the support bar 40 is positioned at the first end, so that the support bar 40 can support or pull the sealing member 20 to stabilize the sealing member 20 at the second position. In the case where the projection is slid to the second end (the support bar 40 is hidden), the seal 20 may be placed in the first position.

In this way, the user only needs to move the other end of the supporting rod 40 to switch the sealing member 20 between the first position and the second position, so that the user operation is convenient.

Alternatively, one end of the support rod 40 may be hinged with the housing 10, and the other end of the support rod 40 may not be connected with the sealing member 20.

Thus, with the seal 20 in the second position, the user can move the other end of the support bar 40, rotate the other end of the support bar 40 about the hinge shaft, and cause the other end of the support bar 40 to support the seal 20 to stabilize the seal 20 in the second position. When it is desired to have the seal 20 in the first position, the other end of the support rod 40 can be moved away to allow the seal 20 to move from the second position to the first position.

Illustratively, the support bar 40 may be a conventional bar body; the support bar 40 may also be a telescopic bar, for example. The support rod 40 may be a general telescopic rod or a telescopic rod (e.g., an electric telescopic rod) with a driving device. At this time, the telescopic rod is connected to the housing 10, and the end of the telescopic rod which can be extended is slidably connected to the seal 20. The user controls the extension and retraction of the telescoping rod which moves the seal 20 between the first and second positions.

Fig. 4 shows a schematic partial structure of an optical cross box 1000 according to an embodiment of the present application. Further, the number of the telescopic rods may correspond to the number of the above-mentioned sealing members 20. For example, as shown in fig. 4, the embodiment of the present application provides two support bars 40.

Alternatively, the other end of the support rod 40 may also be hinged to the seal 20. For example, the other end of the support rod 40 may be connected to an end of the seal member 20 remote from the connection of the seal member 20 and the housing 10. The support bar 40 may be a folding bar.

With the seal 20 in the second position, the user may extend the support bar 40 such that the support bar 40 supports or pulls the seal 20, thereby stabilizing the seal 20 in the second position. With the seal 20 in the first position, the user may fold the support bar 40 (conceal the support bar 40) while the seal 20 is in the first position (similar to a folding bar provided on a window, opening the window, the folding bar being unfolded, the folding bar supporting the window; closing the window, folding the folding bar).

Alternatively, one end of the support rod 40 may be slidably coupled to the housing 10, and the other end of the support rod 40 may be hinged to the sealing member 20. A limiting device may be provided on the housing 10 for limiting one end of the support bar 40 to a third position.

In the case that one end of the support bar 40 is slid to a certain position (where the support bar 40 may be located at the third position), the sealing member 20 is located at the second position, and the user may limit one end of the support bar 40 at the third position by using the limiting device, and since the other end of the support bar 40 is hinged to the sealing member 20, the sealing member 20 may be stabilized at the second position.

In the case where one end of the support bar 40 is slid to another position (where the support bar 40 may be located in the fourth position), the seal 20 is located in the first position.

In some embodiments, as further shown in fig. 4, the light box 1000 further includes a driver 50, the driver 50 being coupled to the housing 10 and coupled to the support bar 40. The driver 50 drives the support bar 40 between the third position and the fourth position.

The user can move the support bar 40 between the third position and the fourth position by simply manipulating the driver 50, which is convenient. In addition, the driver 50 is further configured to avoid the user applying force to the support rod 40, so that the support rod 40 moves between the third position and the fourth position, thereby saving a part of manpower.

The drive 50 may be an electric motor, for example. Reference may be made to the working principle of an electric telescopic rod or an electric push rod, and this will not be described in detail in this embodiment.

The driver 50 may also be a cylinder, for example. For example, a cylinder may be connected to the housing 10, an output end of the cylinder may be connected to one end of the support rod 40 (or the output end of the cylinder may be directly connected to the sealing member 20), and the other end of the support rod 40 may be connected to the sealing member 20.

Thus, the output end of the cylinder can drive the support rod 40 to move between the third position and the fourth position.

The actuator 50 may also be a hydraulic cylinder, for example. The setting mode of the hydraulic cylinder can refer to the setting mode of the cylinder, and the embodiment of the application will not be repeated.

For example, the sealing member 20 may not be connected to the housing 10, the output end of the driver 50 may be connected to one end of the support rod 40 (or directly connected to the sealing member 20), and the other end of the support rod 40 may be connected to the sealing member 20. The output of the driver 50 moves the support rod 40 between the third and fourth positions, translating the seal 20 between the first and second positions.

In contrast to the description of the adaptor above, the adaptor may include the driver 50 and the support post 40, or the adaptor may include the driver 50.

For example, in the case of a rotary connection of the seal 20 with the housing 10, the drive element may be an electric motor. For example, the output shaft of the motor may be connected to the seal 20.

In the embodiment of the application, the sealing element 20 is driven to rotate around the rotation connecting shaft of the sealing element 20 and the shell 10 by the rotation of the motor, so that the sealing element 20 is switched between the first position and the second position. Therefore, the user only needs to operate the motor, the motor can be switched between the first position and the second position, and the operation is convenient.

Fig. 5 shows a schematic structural diagram of a rear side of a light traffic box 1000 according to an embodiment of the present application. In some embodiments, the light box 1000 further comprises: a first temperature sensor 60, a second temperature sensor 70, a humidity sensor and a controller. As shown in fig. 5, the first temperature sensor 60 is disposed outside the casing 10, and detects the air temperature outside the casing 10.

As further shown in fig. 4, a second temperature sensor 70 is provided in the housing 10 for detecting the air temperature in the accommodating chamber 11. The humidity sensor is provided outside the case 10 (for example, the humidity sensor may be provided at the same position as that of the first temperature sensor 60) for detecting the humidity of the air outside the case 10. The controller (provided on the housing 10, for example, the controller may be provided at the same position as that of the first temperature sensor 60 or the second temperature sensor 70) is electrically connected to each of the first temperature sensor 60, the second temperature sensor 70, the humidity sensor, and the driver 50, and is configured to:

acquiring a first air temperature, a second air temperature and air humidity, wherein the first air temperature is the air temperature outside the shell 10, and the second air temperature is the air temperature in the accommodating cavity 11; when the air humidity is greater than or equal to the preset humidity and the difference between the first air temperature and the second air temperature is greater than or equal to the preset difference, the driver 50 is controlled to act so as to enable the support rod 40 to move to the fourth position, and therefore the sealing element 20 can move from the second position to the first position; when the air humidity is less than the preset humidity and the difference between the first air temperature and the second air temperature is less than the preset difference, the driver 50 is controlled to act, so that the support rod 40 moves to the third position, and the sealing member 20 can be stabilized at the second position.

When the air humidity is greater than or equal to the preset humidity and the difference between the first air temperature and the second air temperature is greater than or equal to the preset difference, the controller controls the driver 50 to act, so that the support rod 40 moves to the fourth position, and the sealing member 20 can move from the second position to the first position. It can be understood that at this time, the air humidity outside the light traffic box 1000 is larger, and the air temperature outside the housing 10 is larger than the air temperature difference in the accommodating cavity 11, and the sealing member 20 can move to the first position to seal the heat dissipation hole 12, so that the outside moist air can be prevented from entering the light traffic box 1000 through the heat dissipation hole 12, and condensed dew is generated when meeting condensation, and drops onto the communication device, which results in the communication device not working normally.

It should be noted that the first air temperature should not be too high or too low at this time within a certain range (for example, -40 ℃ C. Or less than 60 ℃ C.). In the event that the first air temperature is too high, the operation of the communication device may be affected and the user may need to move the seal 20 to the second position. Under the condition that the first air temperature is too low, the communication equipment cannot work normally.

When the air humidity is less than the preset humidity and the difference between the first air temperature and the second air temperature is less than the preset difference, the controller controls the driver 50 to act, so that the support rod 40 moves to the third position, and the sealing member 20 can be stabilized at the second position. It will be appreciated that at this point the air humidity outside the light box 1000 is less and the difference between the air temperature outside the housing 10 and the air temperature in the receiving chamber 11 is less. The seal 20 is stabilized at the second position, so that the accommodating chamber 11 communicates with the outside through the heat radiation hole 12, dew is hardly formed even if the outside air enters the light traffic box 1000 through the heat radiation hole 12, and a certain heat radiation effect can be also achieved.

In this way, the first temperature sensor 60, the second temperature sensor 70, the humidity sensor and the controller are provided in the embodiment of the present application, and the controller can correspondingly control the action of the driver 50 according to the temperature and the humidity detected by the above sensors, so that the support rod 40 drives the sealing element 20 to switch between the first position and the second position, thus, the manual driving of the support rod 40 can be replaced, the manpower is saved, and the intellectualization of the position switching of the sealing element 20 is improved.

The first temperature sensor, the second temperature sensor, the humidity sensor and the controller are existing equipment and can be selected according to requirements.

The first temperature sensor 60 and the second temperature sensor 70 may be a thermocouple, a thermistor, a Resistance Temperature Detector (RTD), an IC temperature sensor, or the like, which is not limited in the embodiment of the present application.

When the air humidity is smaller than the preset humidity and the difference between the first air temperature and the second air temperature is smaller than the preset difference, the fan is controlled to operate. As can be seen from the description of the above embodiment, at this time, the sealing member 20 is located at the second position, and the air in the accommodating cavity 11 can be communicated with the external air through the heat dissipation hole 12.

And when the air humidity is greater than or equal to the preset humidity and the difference between the first air temperature and the second air temperature is greater than or equal to the preset difference, the controller controls the fan to stop. As can be seen from the description of the above embodiment, the sealing member 20 is located at the first position, the heat dissipation hole 12 is blocked, and the air in the accommodating cavity 11 cannot circulate with the air outside the accommodating cavity 11.

In this way, the cover 80 protects the communication device from damage by the blower when the blower is in operation. The first ventilation hole 81 allows air in the accommodating space to circulate with air in the accommodating chamber 11.

Illustratively, the blower may be snapped into the housing 10. For example, as further shown in fig. 4, two clamping grooves 90 may be provided on the inner wall surface of the housing 10 at intervals, and the notches of the clamping grooves 90 may be opposite. The fan is connected to the card 100. The card 100 is capable of mating with the card slot 90.

The user can connect the fan with the inner wall surface of the housing 10 by engaging the card 100 into the card slot 90. The user can also take out the cardboard 100 from the draw-in groove 90 to dismantle the fan from casing 10, maintain, so, the user installs and dismantle the fan comparatively conveniently.

In this way, the fastener can limit the clamping plate 100 in the clamping groove 90, so as to prevent the clamping plate 100 and the fan from moving randomly.

The fan may also be connected to the housing 10 by a threaded connection, welding, bonding, riveting, etc. as examples, which are not limited in this embodiment.

In some embodiments, the light box 1000 further comprises: a water absorbing member for absorbing moisture in the air in the accommodating chamber 11. In this way, the water absorbing member can reduce the air humidity in the accommodating chamber 11 and reduce the probability of dew formation in the light box 1000.

In some embodiments, as further shown in fig. 3, the light box 1000 further includes a dust filter screen 130, the dust filter screen 130 being disposed at the heat sink 12. The dust filter 130 serves to prevent dust from entering the accommodating chamber 11 through the heat radiation holes 12. Thus, dust can be prevented from entering the optical cross box 1000, dust is accumulated in the connecting port of the equipment, and poor contact occurs.

Illustratively, the support rod 40 may pass through the dust filter net 130. In addition, the number of the dust filter nets 130 may correspond to the number of the heat dissipation holes 12, for example, as shown in fig. 2, two dust filter nets 130 are provided in the embodiment of the present application.

The water absorbing plate 140 absorbs dew formed in the light traffic box 1000, so that dew can be prevented from dripping onto the communication device, and the communication device cannot work normally. In addition, the third ventilation holes 141 may circulate air at both sides of the water absorbing sheet 140, thereby radiating heat for the communication device.

As an example, as further shown in fig. 2, the water absorbing sheet 140 may be placed on the above-mentioned storage frame 120.

The water absorbing sheet 140 may be disposed on an inner wall surface (sidewall surface, top wall surface or bottom wall surface) of the light traffic box 1000, which is not described herein.

In this way, the top cover 150 can shield the top of the housing 10 and the first temperature sensor 60, the second temperature sensor 70, the humidity sensor and the controller.

For example, the projected area of the top cover 150 on the ground may be larger than the projected area of the case 10 on the bottom surface. For example, as further shown in FIG. 2, a portion of the top cover 150 may protrude beyond the housing 10. Further, as further shown in fig. 5, the outer wall surface of the top cover 150 may be provided with a slope.

Illustratively, the top cover 150 may be integrally designed with the housing 10. The top cover 150 may also be connected to the housing 10 by welding, bonding, screwing, clamping, etc., which is not limited in this embodiment.

In some embodiments, as shown in fig. 7, the housing 10 is provided with an opening 14. The light box 1000 further includes: door 160. Door 160 is hinged to opening 14 of housing 10 (e.g., door 160 may be connected to opening 14 of housing 10 by a hinge), and door 160 is used to close opening 14.

In this way, when the door 160 closes the opening 14, a certain sealing effect can be achieved, so that moist air outside the housing 10 is prevented from entering the accommodating cavity 11 through the opening 14. In addition, the user may open the door 160 to service and maintain the communication device and the blower.

In some embodiments, continuing to refer to fig. 7, the light box 1000 further comprises: the base 170, the base 170 is disposed at the bottom of the housing 10. In the case of a heavy light box 1000, the base 170 may serve a certain supporting function.
