Any good hardware or electrical store should be able to supply you with one. But do you know why the fuse blew? It could indicate an underlying fault which, in the worst case, could make the fan dangerous. Any signs of cracked or broken insulation on the lead, or damage to the plug? Any such faults must be corrected before going further. In fact, you'd do well to get it checked out and safety-tested by an electrical contractor.
