The working principle of the invention is as follows:
in the rainy day, since moisture increases, it is required that the dehumidifying plate 21 remove water vapor in the air to prevent the damage of the internal parts of the container body 1, as in the state of fig. 2, rainwater is concentrated in the water collecting tank 231, so that the water collecting tank 231 presses the top block spring 232 due to the gravity of water, so that the top block 231 moves downward, the top block inclined surface 2313 presses the block inclined surface 2331, so that the block 233 presses the block spring 234 to move backward, the block 233 is retracted into the horizontal section 2247, the dehumidifying plate 21 is not restricted, the exhaust fan operates, external air enters from the large filter screen 221, passes through the upper vent 2241 after removing the water vapor in the air by the front dehumidifying plate 211 and enters the inside of the container body 1, the blower blows out hot air in the container body 1 from the lower ventilation holes 2242, when the hot air passes through the rear dehumidification board 212, moisture in the water absorbing material in the rear dehumidification board 212 is dried, after a period of time, the water absorbing material in the front dehumidification board 211 becomes heavier and heavier due to water absorption, the rear dehumidification board 212 becomes lighter and lighter, so that the front dehumidification board 211 moves downwards with the assistance of the racks 2116 and the gears 2117, the rear dehumidification board 212 moves upwards, the upper and lower positions of the front dehumidification board 211 and the rear dehumidification board 212 are interchanged, and after a period of time, the positions of the front dehumidification board 211 and the rear dehumidification board 212 are interchanged again, and finally the recycling of the dehumidification board 21 is realized;
in the weather, the existence of the dehumidifying plate 21 is redundant due to the fact that the outside air is dry, and the ventilation effect is affected, so that the limiting device 23 is arranged, as shown in the state of fig. 8, when the water in the water collecting tank 231 is evaporated, the top block 231 moves upwards due to the action of the top block spring 232, the extrusion of the top block 231 to the stop block 233 is released, the stop block 231 moves leftwards under the action of the stop block spring 234, the stop block inclined surface 2331 stretches into the outer frame 224, and when the front dehumidifying plate 211 and the rear dehumidifying plate 212 alternate up and down, the stop block inclined surface 2331 clamps the upper end of the front dehumidifying plate 211 and the lower end of the rear dehumidifying plate 212, so that wind can shuttle from the upper side of the front dehumidifying plate 211 and the lower end of the rear dehumidifying plate 212, the blocking of part of the dehumidifying plate 21 to wind force is reduced, and the ventilation effect is better.
