Waterproof assembly for a blower

Abstract

A waterproof assembly is provided to an air blower and has a cap adapted to be securely mounted on top of the circuit board and a primary seal is adapted to be sandwiched between the motor casing and the circuit board. A through hole is adapted to be defined through a periphery of the motor casing and a tube is extendable into the through hole to allow extension of control wires. A secondary seal is sandwiched between the tube and the periphery defining the through hole and a frame is adapted to be formed on the periphery defining the through hole of the motor casing and has a step to support the primary seal. The circuit board is mounted on top of the frame to sandwich the primary seal.

1 . In an air blower comprising a motor casing and a circuit board, wherein the improvement comprises:
 a cap is adapted to be securely mounted on top of the circuit board and a primary seal is adapted to be sandwiched between the motor casing and the circuit board.   
   
   
       2 . The air blower as claimed in  claim 1 , wherein a through hole is adapted to be defined through a periphery of the motor casing and a tube is extendable into the through hole. 
   
   
       3 . The air blower as claimed in  claim 2 , wherein a secondary seal is sandwiched between the tube and the periphery defining the through hole. 
   
   
       4 . the air blower as claimed in  claim 3 , wherein a frame is adapted to be formed on the periphery defining the through hole of the motor casing and has a step to support the primary seal, the circuit board is mounted on top of the frame to sandwich the primary seal.
