Abstract

The application provides a fan for rescue, which comprises a fan assembly, an air pipe assembly and a power supply assembly for supplying power to the fan assembly, the air inlet and the air outlet of the fan assembly are respectively located at two opposite ends, and two first connecting heads are respectively arranged at the air inlet and the air outlet; one end of the pipe body of the air pipe assembly is connected with a second connecting head, and the second connecting head is used for being connected with the first connecting head, so that the fan for rescue can present an air supply state or an air exhaust state, and the function is more diversified; and fresh air is directly blown out from the air pipe for the rescue personnel and the trapped personnel to breathe, and the action convenience of the rescue personnel can be improved due to the absence of a breathing mask, so that an open view can be obtained even in a narrow and closed space, and the occupied operation space is reduced. The application has a small and simple structure, is fast to assemble, is convenient to carry, is especially suitable for being used in a narrow and closed space, and is convenient for the action of the rescue personnel.
