On the other hand, the screw 202 can also drive the negative pressure fan 203 to rotate rapidly, external air flow is pumped into the spiral pipe 204 through the air inlet pipe II, the external air flow rotates at a high speed when entering the spiral pipe 204, water drops doped in the air flow adhere to the pipe wall of the spiral pipe 204 under the action of centrifugal force, further, a metal sheet is arranged on the inner wall of the lower portion of the spiral pipe 204, and the refrigerating end of the thermoelectric refrigerator 205 is fixedly connected with the metal sheet, so that the temperature of the inner wall of the lower portion of the spiral pipe 204 is reduced, water vapor in the centrifuged air flow is liquefied again, the air flow is further dried, a plurality of vertically arranged capillary tubes are arranged on the inner wall of the spiral pipe 204, the gathered water drops are discharged through capillary action, finally, after the external air flow enters the cabinet body, water drops mixed in the air flow are obviously reduced through the centrifugal action, then, the water vapor still existing in the air flow is liquefied and discharged through the action of the refrigerating end of the thermoelectric refrigerator 205, and a large amount of water vapor is discharged in the air flow in the two-stage process.
Then, the airflow enters between the baffle plate and the annular plate 213 through the air inlet pipe I208, three fan-shaped cavity structures are formed between the three baffle plates and the annular plate 213, and the three fan-shaped cavity structures are filled with the silica gel particles 215, so that the silica gel particles 215 are fully contacted with the airflow entering from the air inlet pipe I208 again, the silica gel particles 215 absorb a small amount of water vapor in the airflow, the air with high drying degree enters the cabinet body 1 for circulation and heat dissipation, the water vapor is prevented from entering the cabinet body 1, rusty spots are generated in the cabinet body 1, and the normal work of electric elements in the cabinet body 1 is influenced.
When the silica gel particles 215 in the fan-shaped cavity structure adsorb water vapor to saturation, the self gravity of the silica gel particles will change, and then the silica gel particles 215 after water absorption saturation will push the baffle plate and the annular plate 213 to rotate, so that the fan-shaped cavity structure adjacent to the fan-shaped cavity structure rotates for a certain angle, and further the silica gel particles 215 which do not absorb water correspond to the air inlet pipe I208, and the air flowing out from the air inlet pipe I208 is continuously dried.
Meanwhile, the silica gel particles 215 which are saturated with water are in contact with the sliding block 210 after rotating, the metal block 212 is in a wedge-shaped structure, the side wall of the annular plate 213 is also in a wedge-shaped structure, so that when the annular plate 213 rotates in the circular cavity 206 in a sealed manner for a certain angle, the extrusion metal block 212 retracts, then the annular plate 213 is separated from the metal block 212, the metal block 212 extends out of one end to be in contact with the silica gel particles 215 which are saturated with water, and the heating end of the thermoelectric refrigerator 205 is connected with the metal block 212, so that the metal block 212 heats and dries the silica gel particles 215 which are saturated with water, the silica gel particles 215 can be recycled, and the annular plate 213 and the three baffles rotate automatically under the change of the water absorption gravity of the silica gel particles 215, so that triple removal of water drops in the outside air flow is completed, the ventilation performance in seasons with more rainwater is ensured, and more moisture cannot be brought into the cabinet body 1, rust spots are generated, and normal operation of electric elements in the cabinet body 1 is influenced.
When rainwater stops dry in sunny days, the thermoelectric refrigerator 205 is stopped by the humidity sensor 409, the motor 301 is rotated reversely by the control switch, so that the cover plate 402 is gradually separated from the vent hole 501, and simultaneously, under the action of the first spring 408, the sliding plug 407 extrudes the rainwater in the first cavity 405 to the water spray head at the vent hole 501 for spraying, so as to wash the surface of the filter screen frame brushed by the bristle handle 503 from inside to outside, and the washed water and dirt flow out of the cabinet body 1.
