         13 . The fan as in  claim 1 , wherein an outer circumference of the fan guard is covered with an elastomeric material. 
     
     
         14 . The fan as in  claim 3 , further comprising an auxiliary leg extending from the base portion. 
     
     
         15 . The fan as in  claim 14 , wherein the at least one leg is tiltable relative to the base portion, so that the auxiliary leg can be folded over the main body. 
     
     
         16 . A fan comprising:
 a main body having an electric motor and a fan blade assembly rotatably driven by the electric motor;   a support device configured to support the main body; and   a battery mount device provided on at least one of the main body and the support device,   wherein the battery mount device is configured to be able to mount and remove a battery pack at least when the main body is supported on an installation surface via the support device.   
     
     
         17 . A fan comprising:
 a main body having an electric motor and a fan blade assembly rotatably driven by the electric motor;   a support device configured to support the main body and having a contact surface for contacting an installation surface, so that the main body can be supported on the installation surface via the support device with the contact surface contacting the installation surface;   wherein the support device includes a base portion and at least one leg connecting between the main body and the base portion; and   a battery mount device provided on the base portion and configured to be able to mount and remove a battery pack substantially in a horizontal direction when the main body is supported on the installation surface.   
     
     
         18 . The fan as in  claim 17 , wherein the at least one leg comprises two legs, and the base portion extends between the two legs, and each of the two legs has the contact surface. 
     
     
         19 . The fan as in  claim 18 , wherein the two legs are tiltable relative to the base portion. 
     
     
         20 . A fan comprising:
