The invention relates to a combustion chamber blowing cleaning device in the coke oven building process. The device comprises an electric angle compressed air pipeline operating head and a visual operating end; the electric angle compressed air pipeline operating head comprises a compressed air tube body, an angle head, an electric support and a camera, the angle head is hinged to the end portion of the compressed air tube body and communicates with the compressed air tube body, two ends of the electric support are respectively connected with the compressed air tube body and the angle head, the angle head rotates relative to the compressed air tube body under the action of the electric support, and the camera is arranged on the compressed air tube body; and the visual operating end comprises a mounting rod, and an operating handle and a monitor which are fixed on the mounting rod, the operating handle is electrically connected with the electric support, and the monitor is electrically connected with the camera. The angle head can rotate relative to the compressed air tube body, and the horizontal direction of the angle head can be changed by rotating the compressed air tube body in order to realize dead angle-free blowing cleaning; and the blowing cleaning process adopts the visual operation, so the working efficiency is high.
