[0002] Studies have shown that the humidity in the air environment has a great impact on the display and preservation of precious objects such as cultural relics in museums, folk collections, and artworks. At the same time, the humidity required for the storage environment of different precious objects also varies according to factors such as the material, age, and production process of the objects. The humidity of the air environment also varies due to differences in geographical location, altitude, seasonal climate, etc.

[0003] Common dehumidification methods include semiconductor refrigeration dehumidification, compressor refrigeration dehumidification, etc., while the humidification method is to discharge liquid water into the exhibition environment by gasification or atomization. This method requires artificial drainage or water addition, which is very dangerous for museums and exhibition halls with extremely high requirements for exhibition environment. Artificial water addition and drainage will greatly increase the risk of damage to cultural relics and artworks, and serious losses will occur once water leakage occurs.

[0004] In order to solve the above problems, constant humidity machines are used. However, during use, existing constant humidity machines are unable to perform precise quantitative control of the humidity in the air according to the external environment, which easily increases the energy consumption of the constant humidity machines and causes waste of resources.

An air volume regulating mechanism is installed near the pipe mouth in the air pipe 6, and the air volume regulating mechanism is connected to the control unit.

[0027] The air volume adjustment mechanism includes a circular plate 10 and a plurality of wind plates 8. The wind plates 8 are arc-shaped plates. The circular plate 10 is rotatably mounted on the outer surface of the air pipe 6. A fixing rod 9 is installed in the air pipe 6. A plurality of wind plates 8 are rotatably mounted in the air pipe 6 at even intervals. The plate surfaces of the plurality of wind plates 8 are connected together to form a circle.

[0028] The first connecting shaft 11 and the second connecting shaft 12 are fixedly installed at both ends of the wind plate 8 close to the air pipe 6 and the fixed rod 9, respectively. The end of the first connecting shaft 11 passes through the side wall of the air pipe 6. The circular plate 10 fits against the outer side of the first connecting shaft 11 to frictionally drive the first connecting shaft 11 to rotate. A driving mechanism for controlling the rotation of the circular plate 10 is installed on the outer wall of the equipment box 4.

[0029] The driving mechanism includes a forward and reverse motor 13, which is fixedly mounted on the outer wall of the equipment box 4. A gear 15 is coaxially mounted on the output shaft of the forward and reverse motor 13, and a gear ring 14 is mounted on the outer side of the annular plate 10. The gear 15 is respectively meshed with the gear rings 14 on the annular plate 10 at the air inlet and the air outlet. The rotation direction and angle of the gear 15 are controlled by the forward and reverse motor 13, and then the rotation direction and angle of the annular plate 10 are controlled, so as to achieve precise control of the rotation angle of the wind plate 8.

[0030] A cleaning mechanism for cleaning the ventilation hole 7 is installed in the chassis 1. The cleaning mechanism includes a square rod 16. The square rod 16 is slidably installed on the inner wall of the chassis 1 near the ventilation hole 7. The left and right inner walls of the chassis 1 are provided with a slide groove 22. A slider 23 is provided in the slide groove 22. The square rod 16 is fixedly installed between the two sliders 23. The slide groove 22 and the slider 23 are provided to make the movement of the square rod 16 smoother. Brush bristles are installed near the ventilation hole 7 of the square rod 16. When the brush bristles pass through the ventilation hole 7 on the side wall of the chassis 1, the ventilation hole 7 is cleaned. The bottom of the square rod 16 is connected to a telescopic mechanism, which is installed at the bottom of the chassis 1.

[0031] The telescopic mechanism includes a square tube 18 and a support rod 17. The support rod 17 is slidably sleeved in the square tube 18. A spring 19 is fixedly connected between the end of the support rod 17 and the bottom of the square tube 18. A cavity is provided in the support rod 17. The cavity of the support rod 17 is connected to the square tube 18. A first air hole 20 is provided near the top of the square tube 18. A second air hole 21 is provided in the cavity of the support rod 17. An inflation mechanism is connected to the square tube 18. The inflation mechanism includes an elastic hose, which is connected between the equipment box 4 and the square tube 18.

[0032] By inflating the square tube 18, the internal air pressure increases, and the support rod 17 can move upward in the square tube 18, and the support rod 17 drives the square rod 16 to move. When the square rod 16 passes through the highest ventilation hole 7, the first air hole 20 and the second air hole 21 overlap, and the air in the square tube 18 flows out, so that the support rod 17 rises to a certain height and then stops rising, and the pressure in the square tube 18 is maintained in a stable state. When the device box 4 stops working, the support rod 17 will move downward under the action of the spring 19, and the bristles will clean the ventilation hole 7 again.

[0033] Specific implementation method: When the humidity data collected by the humidity sensor is higher than the humidity parameter set by the display screen 3, the environment needs to be dehumidified, and the control unit receives the signal information transmitted by the humidity sensor and controls the equipment box 4 to work.

[0034] The equipment box 4 allows the air in the environment to enter the equipment box 4 through the air inlet, and the solid polymer electrolyte membrane of the electrolytic dehumidification element 5 works. The water molecules in the air are separated into hydrogen ions and oxygen at the anode. The hydrogen ions pass through the electrolytic membrane to reach the cathode side. On the cathode side, the hydrogen ions react with the oxygen in the air to produce water molecules and discharge, thereby achieving a dehumidification effect. By controlling the reaction direction of the electrolytic dehumidification element 5, humidification can also be performed. The same air inlet and outlet are set on both sides of the equipment box 4, which can accelerate the circulation of air and effectively improve the efficiency of dehumidification or humidification.

[0035] During the rotation of the annular plates 10 on the air pipes 6 at the air inlet and the air outlet, the friction force drives the first connecting shaft 11 to rotate, and the rotation of the first connecting shaft 11 drives the air plate 8 to rotate. The forward and reverse motors 13 are used to control the direction and angle of rotation of the gear 15, and the gear 15 simultaneously meshes with the gear rings 14 of the annular plates 10 on the two air pipes 6, thereby controlling the rotation angle of the annular plates 10, and at the same time controlling and adjusting the rotation angle of the air plate 8, so that the air intake and air outlet of the two air pipes 6 can be quantitatively and effectively controlled, respectively, to achieve quantitative humidification or dehumidification of the environment.

[0036] The ventilation holes 7 on the upper side wall of the chassis 1 may be adhered with dust and impurities. If they are not cleaned in time, the effect of air intake and air outlet will be greatly affected. By filling part of the air in the equipment box 4 into the square tube 18 through the elastic hose, the pressure in the square tube 18 is increased, and the support rod 17 moves upward along the square tube 18 until the square rod 16 passes through the ventilation hole 7 at the highest point. At this time, the first air hole 20 and the second air hole 21 overlap, and the gas in the square tube 18 flows out. At this time, the air pressure in the square tube 18 reaches a balanced and stable state, and the support rod 17 no longer continues to rise. When the equipment box 4 stops working, the support rod 17 will move downward under the action of the spring 19, and the bristles will clean the ventilation holes 7 again. The airflow in the equipment box 4 is cleverly used to clean the ventilation holes 7. It is simple and practical, and greatly saves the investment of resources. At this time, the plate surfaces of the wind plates 8 in the air pipe 6 are connected to each other to form a circular plate, and the air pipe 6 is closed.
