Claim 7:
8. The self-generating movable heat source according to claim 1, wherein the combustion-supporting cooling fan assembly (6) comprises a drive motor (6-1), a combustion-supporting impeller (6-2), a cooling impeller (6-3), a limit bracket (6-4) and a motor aluminum seat (6-5), the combustion-supporting impeller (6-2) and the cooling impeller (6-3) are mounted on the shaft body at both ends of the drive motor (6-1) respectively, wherein the size of the combustion-supporting impeller (6-2) is smaller than the size of the cooling impeller (6-3), and the limit bracket (6-4) fixes the position of the combustion-supporting cooling fan assembly (6) to avoid the scrape of the shell by the cooling impeller (6-3).
