The invention discloses an automatic-dedusting communication box which comprises a communication box body. A
dust collector is arranged at the top of the communication box body, a dust collection pipeis arranged at the input end of the
dust collector and positioned on two sides of the communication box body, a dust collection port is arranged on the inner side of the dust collection
pipe, one end, away from the dust collection
pipe, of the dust collection port penetrates and extends to an inner cavity of the communication box body, a support is arranged in an inner cavity of the dust collection port, a rotating shaft is arranged on the surface of the support, fan blades are arranged on the surface of the rotating shaft, a dust outgoing
pipe is arranged at the output end of the
dust collector, a water tank is arranged at one end, away from the dust collector, of the dust outgoing pipe, a motor is arranged at the top of the water tank, and a rotation shaft is arranged at the output endof the motor. Through mutual cooperation of the dust collection port, the fan blades, the rotating shaft, the dust collection pipe, the dust collector, the dust outgoing pipe, the water tank, the motor, the rotation shaft and a filtering plate, the communication box can be dedusted automatically and has better dedusting effect.
