[0036] like Figure 5 As shown, the handle can facilitate the removal of components such as the dust screen 44.

[0037] A sealing plate 2 is provided between the housing 1 and the cover 3 , a limiting ring 47 abuts against the rear end of the mounting tube 43 , a supporting tube 5 is fixedly connected to the inside of the cover 3 , and an alarm light 6 is fixedly installed on the upper end of the supporting tube 5 .

[0038] For example, the warning light 6 can sound an alarm to remind personnel to repair the device.

[0039] The mounting assembly includes a support plate 7, the inner bottom of the outer shell 1 is fixedly connected to the support plate 7, the upper end of the support plate 7 is fixedly mounted with an inner shell 8, the inner bottom of the inner shell 8 is fixedly connected to a support column 9, the upper end of the support column 9 is fixedly mounted with a mounting plate 10, and a control assembly is arranged between the mounting plate 10 and the inner shell 8.

[0040] Furthermore, a plurality of vent holes are provided at the upper end of the side wall of the inner shell 8, and mounting holes and mounting grooves are staggeredly provided inside the mounting plate 10.

[0041] The sealing assembly 49 includes a limiting rod 491, the horizontal end of the air outlet pipe 48 is internally fixedly connected to the limiting rod 491, the side wall of the limiting rod 491 abuts against the limiting seat 492, the front end of the limiting seat 492 is fixedly connected to a sliding rod 493, the front end of the limiting seat 492 is fixedly connected to a return spring 494, one end of the return spring 494 is fixedly connected to a fixing plate 495, and the front end of the sliding rod 493 is rotatably connected to a rubber plate 496.

[0042] Specifically, when the fan 42 is started, the rubber plate 496 opens under the action of the airflow, the slide rod 493 slides in the fixed plate 495, and the limit seat 492 compresses the return spring 494 to exhaust the air outlet duct 48. When the fan 42 is turned off, under the action of the elastic force of the return spring 494, the rubber plate 496 is driven to reset and the air outlet duct 48 is sealed.

[0043] The return spring 494 is arranged on the outside of the slide rod 493 , the fixing plate 495 is fixedly installed inside the air outlet pipe 48 , the fixing plate 495 is slidably connected to the outer wall of the slide rod 493 , and the rubber plate 496 abuts against the air outlet pipe 48 .

[0044] In this embodiment, the return spring 494 controls the position of the limiting seat 492 .

[0045] The control component includes a fixing ring 11, the inner bottom of the inner shell 8 is fixedly connected with the fixing ring 11, the upper end of the fixing ring 11 is fixedly connected with a filter plate 12, the lower end of the filter plate 12 abuts against an activated carbon plate 13, the lower end of the activated carbon plate 13 is fixedly connected with a support spring 14, one end of the support spring 14 is fixedly connected to the inner bottom of the inner shell 8, and the inner bottom of the inner shell 8 is fixedly connected with a control switch 15.

[0046] On the other hand, the activated carbon plate 13 absorbs the water vapor in the inner shell 8. As the absorbed water vapor increases, the weight of the activated carbon plate 13 increases, and the activated carbon plate 13 begins to fall and squeezes the supporting spring 14, and finally falls on the control switch 15. The control switch 15 controls the alarm light 6 to sound an alarm.

[0047] The activated carbon plate 13 is slidably connected to the inside of the fixing ring 11 , and the supporting spring 14 is sleeved on the outside of the control switch 15 . The control switch 15 is a push switch, and the control switch 15 is electrically connected to the alarm light 6 .

[0048] A humidity sensor 16 is fixedly connected to the inner wall of the back side of the inner shell 8 . A controller 17 is fixedly connected to the inner wall of the back side of the inner shell 8 . The controller 17 is electrically connected to the humidity sensor 16 , the fan 42 and the control switch 15 .

[0049] It is worth noting that the controller 17 controls the operation of the electrical components in the device.

[0050] Two symmetrically distributed first support rods 18 are fixedly connected to the bottom of the housing 1, and two symmetrically distributed second support rods 19 are fixedly connected to the side wall of the housing 1. Both the two first support rods 18 and the second support rods 19 are provided with threaded holes for fixing.

[0051] In some other embodiments, two first support rods 18 and two second support rods 19 are used to install the housing 1 .

[0052] Working principle: When installing the utility model, the inner shell 8 is installed on the support plate 7, various electronic devices are installed on the mounting plate 10, and finally the sealing plate 2 and the cover 3 are installed on the upper end of the outer shell 1 by bolts, and the outer shell 1 is installed by the first support rod 18 and the second support rod 19;

[0053] When in use, the humidity sensor 16 detects the humidity information inside the inner shell 8 in real time, and presents the data to the controller 17 for integration and analysis. When the humidity reaches the specified value, the controller 17 controls and turns on the fan 42 to introduce the outside wind. The dustproof net 44 filters the impurities in the air. The waterproof membrane 46 filters the water vapor in the air to prevent the water vapor from entering the inside of the device. The waterproof membrane 46 filters the water vapor on the surface of the waterproof membrane 46. The water vapor gathers into water and falls on the guide ring 45. Under the guidance of the guide ring 45, it flows to the dustproof net 44 and finally flows out of the air inlet pipe 41. When the fan 42 is started, the rubber plate 496 opens under the action of the airflow, the slide bar 493 slides in the fixed plate 495, and the limit seat 492 compresses the reset spring 494 to exhaust the air outlet pipe 48. When the fan 42 is turned off, under the elastic force of the reset spring 494, the rubber plate 496 is driven to reset and the air outlet pipe 48 is sealed.

[0054] When a component in the moisture-proof component 4 of the device is damaged or the outer shell 1 is damaged, water vapor may enter the inner shell 8, and the activated carbon plate 13 adsorbs the water vapor in the inner shell 8. As the adsorbed water vapor increases, the weight of the activated carbon plate 13 increases, and the activated carbon plate 13 begins to fall and squeezes the supporting spring 14, and finally falls on the control switch 15. The control switch 15 controls the alarm light 6 to sound an alarm, reminding personnel to inspect and maintain the device.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
