Automatic cleaning type filter device

The invention relates to the field of filter technologies, in particular to an automatic cleaning type filter device which comprises a main water inlet pipe, a top plate, a support plate, a bottom plate, a device body and a dirt collecting barrier. A plurality of filter net pipes are arranged in the automatic cleaning type filter device, a cleaning brush plate corresponds to the filter net pipes and can move in the up-down directions, and accordingly the filter net pipes can be cleaned; to-be-filtered water can flow to pull the cleaning brush plate via a left pull block and a right pull block to move in the up-down directions, impurities attached to the surfaces of the filter net pipes can be carried away by the cleaning brush plate in movement procedures, effects of automatically cleaning the filter net pipes can be realized, and clear water which flows through the filter net pipes can flow out from a clear water outlet pipe. The automatic cleaning type filter device has the advantages that the automatic cle
