[0031] One end of the ventilation duct 16 is set as a square frame, and one side of the fan 14 is provided with a square groove, which is adapted to the square frame at one end of the ventilation duct 16. The two are slidably inserted and connected, tightly attached, and leaving no gap.

The middle of the fan 14 is connected with the interior of the ventilation duct 16. When installing the ventilation duct 16 and the fan 14, the square frame at one end of the ventilation duct 16 can be inserted into the square groove on one side of the fan 14, and then the anti-slip screw 13 can be rotated and screwed in, so that the anti-slip screw 13 is simultaneously passed through the fan 14 and the ventilation duct 16, so that the fan 14 and the ventilation duct 16 are fixed. Similarly, the anti-slip screw 13 can be rotated in the opposite direction to completely remove it from the fan 14 and the ventilation duct 16, so that the fan 14 and the ventilation duct 16 can be disassembled.

[0032] The other two ends of the two ventilation ducts 16 are provided with slide grooves 24 near the first anti-touch net 10. Four groups of electromagnetic sliders 25 are provided.

When the PLC controller 5 controls the electromagnetic slider 25 to slide along the inside of the slide groove 24, the electromagnetic slider 25 can drive the blocking door 18 to move at the same time. As the blocking door 18 moves to the upper end or lower end of the ventilation duct 16, the blocking door 18 will close the upper end or lower end of one side of the ventilation duct 16, so that the air can only enter the cabinet 1 along the lower end or upper end of the ventilation duct 16.

[0033] The PLC controller 5 is embedded in the top front of the cabinet 1, the temperature sensor 9 is embedded in one side of the inner wall of the cabinet 1, the humidity sensor 11 is embedded in the other side of the inner wall of the cabinet 1, two groups of fans 14 are provided, and the two groups of fans 14 are respectively installed in the middle of each group of first anti-touch nets 10 and ventilation ducts 16, the heating rod electrical accessories 19 and the heating rod 20 are installed in the upper end of the other group of ventilation ducts 16, the humidifier 23 is installed in the lower end of one group of ventilation ducts 16, a partition plate 22 is fixed in the middle of the inner wall of the ventilation duct 16, a leakage prevention net 21 is fixed on one side of the upper end of one group of ventilation ducts 16 near the first anti-touch net 10, and multiple groups of silica gel drying bags are placed inside the upper end of one group of ventilation ducts 16.

When the external air passes through the heating rod 20, the space at the upper end of the other set of ventilation ducts 16 has sufficient heat, which will heat the air flowing through, so that the air enters the cabinet 1 with heat, thereby gradually increasing the temperature inside the cabinet 1. When the humidity sensor 11 detects that the humidity in the cabinet 1 is lower than the predetermined threshold, the humidity sensor 11 transmits the humidity signal to the PLC controller 5.The PLC controller 5 sends instructions to two groups of symmetrical electromagnetic sliders 25, so that the two groups of electromagnetic sliders 25 drive one group of blocking doors 18 to move up, until one group of blocking doors 18 closes the upper end of one side of one group of ventilation ducts 16, and then the PLC controller 5 sends instructions to the humidifier 23 again, so that the humidifier 23 is turned on and sprays water mist, and then the PLC controller 5 sends a reverse suction instruction to one group of fans 14, so that the air outside the cabinet 1 passes through the lower end of one group of ventilation ducts 16 and enters the cabinet 1. The air carries the water mist into the cabinet 1 at the same time, so as to achieve the purpose of humidifying the inside of the cabinet 1. On the contrary, when the humidity sensor 11 detects that the humidity inside the cabinet 1 is higher than When the humidity reaches the threshold, the humidity sensor 11 transmits the humidity signal to the PLC controller 5, and the PLC controller 5 issues instructions to two groups of symmetrical electromagnetic sliders 25, so that the two groups of electromagnetic sliders 25 drive one group of blocking doors 18 to move downward, until one group of blocking doors 18 seals the lower end of one side of one group of ventilation ducts 16, and the PLC controller 5 issues a reverse suction instruction to one group of fans 14, so that the air outside the cabinet 1 passes through the upper end of one group of ventilation ducts 16 and enters the cabinet 1, and the moisture in the air will be adsorbed by the silica gel drying bag in the upper end of one group of ventilation ducts 16, and finally the dry air enters the cabinet 1, so as to achieve the purpose of reducing the humidity inside the cabinet 1.
