Shockproof fan apparatus

Abstract

A fan apparatus includes a fan, a shockproof unit, and a case. The fan includes two plates, and a through hole is defined on each plate. The shockproof unit includes a pole penetrating the two though holes, and at least a flange is defined on the pole; at least an elastic element is restricted between one of the plates and the flange. Two ends of the pole protrude from the through holes and abut on the case when the fan is received in the case. A concave groove is defined on each end of the pole; the concave groove protrudes one of the through holes and received in a sleeve abutting on the case; a containing hole is defined in the sleeve to receive the end of the pole.

1 . A fan apparatus, comprising:
 a fan comprising two plates; each plate comprising one through hole, and the through holes on the two plates are in opposite positions; and   a shockproof unit comprising a pole penetrating the two though holes; at least one flange defined on the pole, and at least one elastic element, wherein each of the at least one elastic element is restricted between one of the plates and the flange.   
     
     
         2 . The fan apparatus as claimed in  claim 1 , wherein the fan apparatus further comprises a case to receive the fan; two ends of the pole protrude from the through holes and abut on the case when the fan is received in the case. 
     
     
         3 . The fan apparatus as claimed in  claim 2 , wherein a concave groove is defined on each end of the pole; the concave groove protrudes one of the through holes and is received in a sleeve abutting on the case. 
     
     
         4 . The fan apparatus as claimed in  claim 3 , wherein a containing hole is defined in the sleeve to receive the end of the pole. 
     
     
         5 . The fan apparatus as claimed in  claim 3 , wherein the sleeve is made of plastic material. 
     
     
         6 . The fan apparatus as claimed in  claim 2 , wherein at least one spacer is positioned between the fan and the case when the fan is received in the case. 
     
     
         7 . The fan apparatus as claimed in  claim 1 , wherein the shockproof unit comprises at least one gasket, each gasket is positioned between one of the at least one elastic element and the plate restricting the elastic element. 
     
     
         8 . A fan apparatus, comprising:
 a fan comprising two plates; each plate comprising one through hole, and the through holes on the two plates are in opposite positions;   a case to receive the fan; and   a shockproof unit comprising a pole penetrating the two though holes, and two ends of the pole abutting on the case; at least one elastic element penetrated by the pole being restricted between the plate and the case.   
     
     
         9 . The fan apparatus as claimed in  claim 8 , wherein a concave groove is defined on each end of the pole; the concave groove protrudes one of the through holes and is received in a sleeve abutting on the case. 
     
     
         10 . The fan apparatus as claimed in  claim 9 , wherein a containing hole is defined in the sleeve to receive the end of the pole. 
     
     
         11 . The fan apparatus as claimed in  claim 10 , wherein the sleeve is made of plastic material. 
     
     
         12 . The fan apparatus as claimed in  claim 8 , wherein the shockproof unit comprises at least one gasket, each gasket is positioned between one of the at least one elastic element and the plate restricting the elastic element. 
     
     
         13 . The fan apparatus as claimed in  claim 8 , wherein at least one spacer is positioned between the fan and the case.
