Blower

Abstract

A blower has an air outlet duct having an internal space, and an air outlet opening extending from the air outlet duct. A fan having a plurality of blades is positioned inside the internal space. A base seat is positioned below the air outlet duct, with an air inlet provided in a side wall of the base seat, and with an air inlet pipe extending from the air inlet. A motor is positioned in the base seat and has a shaft that extends through the air outlet duct to be coupled to the blades.

1 . A blower that is supported on a surface, comprising:
 an air outlet duct having an internal space, and an air outlet opening extending from the air outlet duct;   a fan having a plurality of blades positioned inside the internal space;   a base seat positioned below the air outlet duct, the base seat having a side wall, with an air inlet provided in the side wall, and an air inlet pipe extending from the air inlet; and   a motor positioned in the base seat and having a shaft that extends through the air outlet duct to be coupled to the blades.   
     
     
         2 . The blower of  claim 1 , wherein the blades are positioned horizontally with respect to the surface. 
     
     
         3 . The blower of  claim 1 , further including a sleeve provided around the air inlet pipe. 
     
     
         4 . The blower of  claim 3 , further including a protective screen provided at one end of the sleeve. 
     
     
         5 . A method of blowing a gas stored in a bottle, comprising:
 a. providing a blower that is supported on a surface, the blower having:
 an air outlet duct having an internal space, and an air outlet opening extending from the air outlet duct; 
 a fan having a plurality of blades positioned inside the internal space; 
 a base seat positioned below the air outlet duct, the base seat having a side wall, with an air inlet provided in the side wall, and an air inlet pipe extending from the air inlet; and 
 a motor positioned in the base seat and having a shaft that extends through the air outlet duct to be coupled to the blades; 
   b. coupling the bottle to the air inlet pipe;   c. drawing the gas from the bottle through the air inlet pipe;   d. passing the drawn gas through the motor before delivering the gas to the air outlet duct; and   e. directing the air from the air outlet duct out of the air outlet opening.   
     
     
         6 . The method of  claim 5 , further including:
 controlling the rate at which the gas flows through the air inlet pipe.
