The invention discloses an electric air blowing apparatus for a backpack type apparatus. The electric air blowing apparatus for the backpack type apparatus comprises an inner side plate and an outer side plate, wherein the inner side plate and the outer side plate are separated by separating pillars, a plurality of fans are evenly distributed on the surface, close to the outer side plate, of the inner side plate, a plurality of buffer blocks are evenly distributed on the surface, away from the inner side plate, of the outer side plate, an air guide channel is formed in each buffer block, the port of each air guide channel extends to the surface, close to the inner side plate, of the outer side plate, a plurality of air guide holes are formed in the side face of each buffer block, and each air guide hole communicates with the corresponding air guide channel. According to the electric air blowing apparatus for the backpack type apparatus, the defect that when a backpack apparatus is in use, heat on the back of the user cannot easily dissipate is overcome, the performance of ventilation is good, the discomfort caused by temperature rise because of heat accumulation can be effectively avoided, and it is avoided that the working clothes of a user gets wet because the user perspires.
