The invention relates to an auxiliary scanning reverse-blowing separating exhausting particle filter which is mainly suitable for compulsively separating the soot particles deposited on the exhaust gas filter of diesel engine. The filter is mainly composed of a housing (5) and the filtering material (4); and the air inlet of the filtering material (4) is communicated with the air inlet of the engine. The invention is characterized in that the inner chamber of the filtering material (4) is provided with a nozzle which is connected with a high-pressure air source through the pipe (16); the pipe (16) and the nozzle (7) whereon are driven by a motor driving mechanism for linear motion, rotation motion or the combination of the linear motion and rotation motion; one or a plurality of nozzle openings (7) are adopted on the nozzle; and the air beam sprayed from the nozzle opening is vertical with the surface of the filtering material. The particles which can not be separated by the inlet air flow and firmly adhere with the surface of the filtering material or are inlayed at the inner part can be compulsively removed so that each regeneration period has no accumulation of deposited particles.
