[0002] With the improvement of the airtightness of modern buildings and the change of climate environment, the problem of excessive indoor air humidity has become a common one. A long-term humid environment not only causes wall mildew and damage to decorative materials, but also is more likely to breed harmful microorganisms, seriously threatening human health. Most traditional dehumidification systems use fixed-air-volume moisture removal fans in conjunction with humidity sensors and electronic control units to achieve start-stop regulation, but there are significant defects in actual applications:
[0003] Most mainstream solutions on the market adjust the air volume by changing the fan speed through a frequency converter. However, such an electric control system has a complex structure, a high failure rate, and requires continuous power supply to maintain operation. When power is cut off or the controller fails, the system completely loses its adaptive ability, and there is a risk of humidity out of control.
[0004] Most traditional moisture removal devices adopt an integral structure with a fixed air duct layout. When it is necessary to expand the dehumidification area, it is necessary to replace high-power equipment or re-arrange the air duct system, resulting in high transformation costs and being difficult to meet the phased transformation requirements of the decoration space.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0027] Embodiment 1
[0028] Please refer to Figures 1-7 , in the embodiment of the present invention, a modular decoration moisture exhaust structure device includes a moisture exhaust fan 50 and at least one moisture exhaust module 10. The moisture exhaust module 10 includes a housing and an air volume adjustment plate 20, a detection plate 30, and a driving mechanism 40 provided inside the housing; a first air inlet 13 and a first air outlet 14 are provided on one side of the housing, a second air inlet 15 and a second air outlet 16 are provided on the other side of the housing, and a humid gas flow chamber and a dry gas flow chamber are provided inside the housing. In this embodiment, taking Figure 1 and Figure 2 as an example, there are two dry gas flow chambers, and the two dry gas flow chambers are located on the upper and lower sides of the humid gas flow chamber. The first air inlet 13 and the second air inlet 15 are communicated with the humid gas flow chamber, and the first air outlet 14 and the second air outlet 16 are communicated with the dry gas flow chamber; in addition, the second air inlet 15 is communicated with the air inlet end of the moisture exhaust fan 50, and the second air outlet 16 is communicated with the air outlet end of the moisture exhaust fan 50. During actual use, the moisture exhaust module 10 can be installed indoors, and the moisture exhaust fan 50 can be installed outdoors. The humid gas indoors flows into the humid gas flow chamber from the first air inlet 13 and then flows into the moisture exhaust fan 50 from the second air inlet 15. After the moisture exhaust fan 50 dries the humid gas, it flows into the dry gas flow chamber from the second air outlet 16 and finally flows into the room through the first air outlet 14, thereby reducing the water content of the indoor gas;
[0029] In the embodiment of the present application, the air volume adjusting plate 20 and the detection plate 30 are both arranged inside the humid gas flow chamber. The detection plate 30 is arranged close to the first air inlet 13, and the air volume adjusting plate 20 is arranged close to the first air outlet 14. The detection plate 30 is slidably installed inside the humid gas flow chamber. When the water content of the indoor air rises, the detection plate 30 slides relative to its initial position. The air volume adjusting plate 20 includes a fixed plate 22 fixedly installed inside the humid gas flow chamber and a moving plate 21 slidably connected to the fixed plate 22. A plurality of first air vents 23 are formed on the fixed plate 22, and a plurality of second air vents 24 are formed on the moving plate 21. The first air vents 23 are communicated with the second air vents 24. In the initial state, the water content of the indoor air is relatively low. At this time, the first air vents 23 and the second air vents 24 are staggered (but still in communication), and the communication area between the first air vents 23 and the second air vents 24 is in the minimum state. When the water content of the indoor air rises, the detection plate 30 shifts its position, and the detection plate 30 controls the moving plate 21 to slide through the driving mechanism, so that the second air vents 24 shift their positions relative to the first air vents 23, and the communication area between the first air vents 23 and the second air vents 24 increases, thereby increasing the amount of humid gas flowing into the dehumidifying fan 50. Correspondingly, the amount of dry gas discharged by the dehumidifying fan 50 is increased, thereby accelerating the flow rate of the humid gas in the room and improving the dehumidification efficiency.
[0030] In the embodiment of the present application, the detection plate 30 is made of a water-absorbing material. A plurality of air holes 31 are formed on the detection plate 30. When the humid gas flows through the air holes 31, the moisture in the gas contacts the water-absorbing material, and the weight of the detection plate 30 increases, causing the detection plate 30 to move towards the first air inlet 13. It should be noted that when the dehumidification module 10 in this embodiment is installed indoors, the first air inlet 13 is vertically oriented.
[0031] In the embodiment of the present application, the driving mechanism 40 includes a first toothed plate 41, a second toothed plate 45, and a third toothed plate 471. A driving chamber is formed on the side of the inside of the housing where the humid gas flow chamber is located. A guide rod 42 is fixedly installed in the driving chamber. The first toothed plate 41 is slidably installed on the guide rod 42, and both sides of the first toothed plate 41 are connected to the inner wall of the driving chamber through telescopic springs 43 sleeved on the guide rod 42. The second toothed plate 45 is slidably installed inside the driving chamber, and a connecting gear 44 is rotatably installed inside the driving chamber. The side of the connecting gear 44 meshes with the first toothed plate 41 and the second toothed plate 45. The side of the detection plate 30 is fixedly connected to the first toothed plate 41. When the detection plate 30 moves towards the first air inlet 13, the first toothed plate 41 drives the second toothed plate 45 to move through the connecting gear 44.
[0032] Further, in the embodiment of the present application, the third toothed plate 471 is slidably installed inside the driving cavity through a sliding seat 47, and the sliding seat 47 is fixedly connected to the second toothed plate 45 through a push rod 46; a threaded groove is formed inside the moving plate 21, and a screw rod 49 is threadedly connected in the threaded groove. One end of the screw rod 49 is fixedly installed with a driving gear 48, and the driving gear 48 meshes with the third toothed plate 471. When the second toothed plate 45 moves, the second toothed plate 45 pushes the third toothed plate 471 to move through the push rod 46, thereby controlling the rotation of the driving gear 48, causing the driving gear 48 to control the rotation of the screw rod 49, and finally controlling the sliding of the moving plate 21.
[0033] It should be noted that, in the embodiment of the present application, two moving plates 21 are provided, and the two moving plates 21 are symmetrically arranged on both sides of the fixed plate 22.

Inside the housing, there are a humid gas flow cavity and a dry gas flow cavity. In this embodiment, taking Figure 1 and Figure 2 as an example, there are two dry gas flow cavities, and the two dry gas flow cavities are located on the upper and lower sides of the humid gas flow cavity. The first air inlet 13 and the second air inlet 15 are communicated with the humid gas flow cavity, and the first air outlet 14 and the second air outlet 16 are communicated with the dry gas flow cavity; in addition, the second air inlet 15 is communicated with the air inlet end of the moisture exhaust fan 50, and the second air outlet 16 is communicated with the air outlet end of the moisture exhaust fan 50. During actual use, the moisture exhaust module 10 can be installed indoors, and the moisture exhaust fan 50 can be installed outdoors. The humid gas indoors flows into the humid gas flow cavity from the first air inlet 13 and then flows into the moisture exhaust fan 50 from the second air inlet 15.

The detection plate 30 is arranged close to the first air inlet 13, and the air volume adjustment plate 20 is arranged close to the first air outlet 14. The detection plate 30 is slidably installed inside the humid gas flow chamber. When the water content of the indoor air rises, the detection plate 30 slides relative to its initial position; the air volume adjustment plate 20 includes a fixed plate 22 fixedly installed inside the humid gas flow chamber and a moving plate 21 slidably connected to the fixed plate 22. A plurality of first air vents 23 are formed on the fixed plate 22, and a plurality of second air vents 24 are formed on the moving plate 21.

At this time, the first air vents 23 and the second air vents 24 are staggered (but remain communicated), and the communication area between the first air vents 23 and the second air vents 24 is in the minimum state. When the water content of the indoor air rises, the detection plate 30 shifts its position, and the detection plate 30 controls the sliding of the moving plate 21 through the driving mechanism, so that the second air vents 24 shift their positions relative to the first air vents 23, and the communication area between the first air vents 23 and the second air vents 24 increases, thereby increasing the amount of humid gas flowing into the dehumidifying fan 50. Correspondingly, the amount of dry gas discharged by the dehumidifying fan 50 is increased, thereby accelerating the flow rate of the humid gas in the room and improving the dehumidification efficiency.
[0037] In the embodiment of the present application, the detection plate 30 is made of a water-absorbing material. A plurality of air holes 31 are formed on the detection plate 30. When the humid gas flows through the air holes 31, the water in the gas contacts the water-absorbing material, and the weight of the detection plate 30 increases, causing the detection plate 30 to move towards the first air inlet 13; it should be noted that when the dehumidification module 10 in this embodiment is installed indoors, the first air inlet 13 is arranged vertically.
[0038] In the embodiment of the present application, the driving mechanism 40 includes a first toothed plate 41, a second toothed plate 45, and a third toothed plate 471.

The side of the connecting gear 44 meshes with the first toothed plate 41 and the second toothed plate 45. The side of the detection plate 30 is fixedly connected to the first toothed plate 41. When the detection plate 30 moves towards the first air inlet 13, the first toothed plate 41 drives the second toothed plate 45 to move through the connecting gear 44;
[0039] Further, in the embodiment of the present application, the third toothed plate 471 is slidably installed inside the driving cavity through a sliding seat 47, and the sliding seat 47 is fixedly connected to the second toothed plate 45 through a push rod 46; a threaded groove is formed inside the moving plate 21, and a screw rod 49 is threadedly connected in the threaded groove. One end of the screw rod 49 is fixedly installed with a driving gear 48, and the driving gear 48 meshes with the third toothed plate 471. When the second toothed plate 45 moves, the second toothed plate 45 pushes the third toothed plate 471 to move through the push rod 46, thereby controlling the rotation of the driving gear 48, enabling the driving gear 48 to control the rotation of the screw rod 49, and finally controlling the sliding of the moving plate 21.
[0040] It should be noted that, in the embodiment of the present application, there are two moving plates 21, and the two moving plates 21 are symmetrically arranged on both sides of the fixed plate 22.
