[0043] Specifically, when the temperature and humidity values inside the prefabricated cabin do not exceed the preset range, the controller 3 controls the start and stop of the fan 2 according to the preset time period, that is, controls the fan 2 to start for a preset duration at each preset time interval. For example, the fan is controlled to start for 15 minutes and then stop every 1 hour.

[0044] It should be noted that a plurality of ventilation openings 4 can be provided on both sides of the prefabricated cabin; when the controller 3 controls a plurality of fans 2 to start, the fans 2 on one side can be controlled to rotate forward, and the fans 2 on the other side can be controlled to rotate backward to realize the air intake and exhaust of the prefabricated cabin and reduce the temperature and humidity inside the prefabricated cabin.

[0045] In other embodiments, a toxic gas detector may also be included. The toxic gas detector is disposed in the prefabricated cabin and electrically connected to the controller, and is used to detect whether there is a gas that meets the preset conditions in the prefabricated cabin. The preset conditions can be set according to the toxic gases that the prefabricated cabin may generate, so as to determine whether there is a toxic gas in the prefabricated cabin. When it is detected that there is a toxic gas, the controller 3 controls the fan 2 to exhaust air. Specifically, it can be to control all the fans 2 to enter the exhaust mode to discharge the toxic gas.

[0046] Wherein, the controller 3 can be electrically connected to the control terminal used by the staff, and a start switch can be connected to the outside of the fan 2, so that the staff can manually control the start and stop of the fan 2 according to the control terminal or the start switch.

The outer through-hole layer 6 is used to block the water droplets outside the heating element 5 from entering the heating element 5. The inner through-hole layer 7 is used for drainage so that the water vapor in the ventilation opening 4 can enter the heating element 5 and then be discharged.

[0051] Further, the inner through-hole 71 is smoothly and transitionally connected to the wall surface of the ventilation opening 4, so that the water vapor on the wall surface of the ventilation opening 4 can directly flow into the inner through-hole 71.

[0052] To increase the shielding effect of the outer through-hole layer 6, the hole wall of the outer through-hole 61 protrudes outward relative to the outer wall surface of the ventilation opening 6, that is, the arc hook on the outer through-hole layer 6 protrudes outward.

[0053] Further, an inner drain hole 72 communicating with the inner through-hole 71 is provided at the bottom of the inner through-hole layer 7; an outer drain hole 62 communicating with the outer side surface of the heating element 5 is provided at the bottom of the outer through-hole layer 6, so that the water vapor naturally falling on both sides of the heating element 5 can be discharged through the inner drain hole 72 and the outer drain hole 62.
