         6 . The blower device according to  claim 3 , wherein the vibration absorption assembly comprises a locating buffering member associated with a top portion of the blower vibration source. 
     
     
         7 . The blower device according to  claim 6 , wherein the locating buffering member comprises a locating ring disposed at the top portion of the blower vibration source and a locating seat which is provided at an inner side of a top portion of the case and is used to receive the locating ring. 
     
     
         8 . The blower device according to  claim 6 , wherein the connection buffering member is configured as a box body in which the blower vibration source is completely received, the locating buffering member comprises buffering members fixed on a top portion of the connection buffering member and extended to the case with cross-sections being gradually decreased, and the support buffering member comprises buffering members fixed on the bottom surface of the connection buffering member and extended to the bottom wall of the case with cross-sections being gradually decreased. 
     
     
         9 . The blower device according to  claim 8 , wherein the connection buffering member comprises a hook-shaped connection part extended horizontally from a side wall of the connection buffering member, the case comprises a hook support part located at an inner side wall of the case, and the hook-shaped connection part is hung on the hook support part. 
     
     
         10 . The blower device according to  claim 6 , wherein the connection buffering member is configured as a box body in which the blower vibration source is completely received, the locating buffering member comprises buffering members fixed on a top wall of the case and extended to the connection buffering member with cross-sections being gradually decreased, and the support buffering member comprises buffering members fixed on the bottom wall of the case and extended to the connection buffering member with cross-sections being gradually decreased. 
     
     
         11 . The blower device according to  claim 10 , wherein the connection buffering member comprises a hook-shaped connection part extended horizontally from a side wall of the connection buffering member, the case comprises a hook support part located at an inner side wall of the case, and the hook-shaped connection part is hung on the hook support part.
