In addition, some aspects disclosed by the present invention can be used alone, or in any appropriate combination with other aspects disclosed by the present invention.

[0022] Embodiment 1

[0023] As Figures 1-4 shown, this is the first embodiment of the present invention. This embodiment provides a moisture-proof control cabinet, including a cabinet body 1. The front of the cabinet body 1 is movably connected to a cabinet door 2 through a hinge. A temperature and humidity sensor 3 is arranged on the front of the cabinet door 2, and the detection end of the temperature and humidity sensor 3 extends into the inner cavity of the cabinet body 1. A dehumidification unit 4 is arranged on the right side of the cabinet body 1. The dehumidification unit 4 includes a dehumidification box 41, and a centrifugal fan 42 is arranged on the top of the dehumidification box 41. One end of the centrifugal fan 42 is communicated with the dehumidification box 41, and the other end is communicated with a transmission pipe 43. The bottom of the transmission pipe 43 is communicated with a suction pipe, and the suction pipe is communicated with the cabinet body 1. The upper end of the inner cavity of the dehumidification box 41 is movably connected to a connecting plate 44, and a grid 45 is fixedly connected to one side of the connecting plate 44. A breathable net 46 is arranged in the inner cavity of the upper grid 45, and hygroscopic cotton 47 and desiccant 48 are respectively arranged in the inner cavities of the middle grid 45 and the lower grid 45. An electric heating pipe 49 is fixedly connected to the lower end of the inner cavity of the dehumidification box 41. The bottom of the dehumidification box 41 is communicated with a connecting pipe 411, and the other end of the connecting pipe 411 is communicated with the cabinet body 1.

[0024] As Figures 1-4As shown in the figure, the cabinet body 1 can be enclosed by the cabinet door 2 to ensure the sealing performance of the cabinet body 1. The temperature and humidity sensor 3 can monitor the temperature and humidity inside the cabinet body 1 in real time. The centrifugal fan 42 enables the transmission pipe 43 to cooperate with the suction pipe to transmit the air containing moisture inside the cabinet body 1 to the inside of the dehumidification box 41. The impurities in the air are intercepted by the breathable net 46, and the moisture in the air is adsorbed and dried by the moisture-absorbing cotton 47 and the desiccant 48. The adsorbed air enters the lower end of the inner cavity of the dehumidification box 41 and is heated by the electric heating pipe 49 to make the air become dry hot air flow, and then enters the inner cavity of the cabinet body 1 again through the connecting pipe 411, thereby realizing the cyclic exchange of air flow and gradually removing the moisture inside the cabinet body 1 to ensure the dryness inside the cabinet body 1.

[0025] Embodiment 2

[0026] Referring to Figure 1 and 3 , this is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, a sealing gasket 21 is fixedly connected to the back surface of the cabinet door 2, and the side of the sealing gasket 21 away from the cabinet door 2 is in contact with the front surface of the cabinet body 1.

[0028] Support rods are fixedly connected to the four sides of the bottom of the cabinet body 1, and a bottom plate 11 is fixedly connected to the bottom of the support rods.

[0029] A sealing strip 442 is fixedly connected to the surface of the connecting plate 44. The side of the sealing strip 442 away from the surface of the connecting plate 44 is in contact with the inner wall of the dehumidification box 41, and a microcontroller 5 is fixedly connected to the right side of 41.

[0030] As Figure 1 and 3 shown, by the contact of the sealing strip 442 with the inner wall of the dehumidification box 41, the sealing performance at the connection between the connecting plate 44 and the dehumidification box 41 is ensured, preventing air from mixing in or leaking. By the contact of the sealing gasket 21 with the cabinet body 1, the sealing performance at the connection between the cabinet door 2 and the cabinet body 1 is ensured, preventing external moisture from entering the inner cavity of the cabinet body 1 through the gap. The cabinet body 1 is supported by the support rods in cooperation with the bottom plate 11, so that the cabinet body 1 does not directly contact the ground, preventing moisture from being conducted through the ground.

[0031] Embodiment 3

[0032] Referring to Figures 2-4 , this is the third embodiment of the present utility model, and this embodiment is based on the previous two embodiments.

[0033] In this embodiment, limiting strips 412 are fixedly connected to the front and back surfaces of the inner cavity of the dehumidification box 41. The bottom of the wire rack 45 is in contact with the limiting strips 412 and is movably connected to the top of the limiting strips 412.

[0034] On the right side of the connecting plate 44, a pulling frame 441 is fixedly connected. On the right side of the dehumidification box 41, a limiting rod 413 is movably connected through a rotating shaft. The limiting rod 413 is located inside the pulling frame 441 and is movably connected to the inner cavity of the pulling frame 441.

[0035] As Figures 2-4 shown, the wire frame 45 can slide along the top of the limiting strip 412. Furthermore, the limiting strip 412 can support the wire frame 45, and can well limit the wire frame 45. By rotating the limiting rod 413, the limiting rod 413 enters the inner cavity of the pulling frame 441, and then the connecting plate 44 can be positioned to ensure the stability of the connecting plate 44.

[0036] During use, first, the cabinet body 1 can be closed through the cabinet door 2 to ensure the sealing performance of the cabinet body 1, effectively preventing external moisture from entering the interior of the cabinet body 1. Moreover, the temperature and humidity sensor 3 can real-time monitor the temperature and humidity inside the cabinet body 1, and the monitored data will be transmitted to the microcontroller 5. The microcontroller 5 analyzes the data. When the data is not within the preset threshold, the microcontroller 5 can make the centrifugal fan 42 operate. Through the centrifugal fan 42, a negative pressure can be generated in the transmission pipe 43 and the suction pipe, and the transmission pipe 43 cooperates with the suction pipe to transmit the moist air inside the cabinet body 1 to the inside of the dehumidification box 41. The impurities in the air are intercepted through the breathable net 46 to ensure the cleanliness of the air. When the air passes through the moisture-absorbing cotton 47 and the desiccant 48, the moisture-absorbing cotton 47 initially adsorbs the moisture in the air, and the desiccant 48 secondarily adsorbs and dries the moisture in the air. And the adsorbed air will enter the lower end of the inner cavity of the dehumidification box 41. Through the operation of the electric heating tube 49 to generate heat, the heat heats the air, making the air become dry hot air flow, and then enters the inner cavity of the cabinet body 1 again through the connecting pipe 411, thereby realizing the cyclic exchange of the air flow and gradually removing the moisture inside the cabinet body 1 to ensure the dryness inside the cabinet body 1.

The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts, and equipment all adopt conventional models in the existing technology. The control method is automatically controlled through a controller, and the control circuit of the controller can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in this field. And this application document is mainly used to protect the mechanical device, so the control method and the circuit connection will not be explained in detail in this application document.
