Intelligent switch cabinet dehumidifier and dehumidification switch cabinet

The invention relates to an intelligent switch cabinet dehumidifier and a dehumidification switch cabinet. The intelligent switch cabinet dehumidifier is arranged in a cabinet body, and a filter plate is arranged in the cabinet body; the intelligent switch cabinet dehumidifier comprises a shell, a heat exchanger, and an air suction head, wherein the shell and the heat exchanger are installed on the outer wall of the cabinet body, the air suction head is movably arranged above the filter plate through a reciprocating structure; when a first driving mechanism works, the air suction head is driven to do first reciprocating rectilinear motion above the filter plate, and in the process, a second driving mechanism is triggered, so that the air suction head does second reciprocating rectilinear motion in the process of doing the first reciprocating rectilinear motion, the first reciprocating linear motion is perpendicular to the second linear reciprocating space; and finally, due to the fact that the two linear motions are conducted at the same time, the air suction head conducts sine type reciprocating motion, humid air absorbed by an air exhaust assembly from the cabinet body through the air suction head is transferred into the heat exchanger to be dehumidified, and then the treated air is discharged into the cabinet body again.
