Vent pipe and blower comprising the same

Abstract

A vent pipe, including: a top plate; two side plates; a base plate; and an air channel formed by the top plate, the two side plates, and the base plate; and an air deflector. The air channel includes a first air inlet and a first air outlet. The air deflector is disposed on the base plate and located on one side of the first air outlet. Also provided is a blower, including a motor; a volute; a blade wheel; and the vent pipe. The volute includes a chamber and the blade wheel is disposed in the chamber. The volute includes a second air inlet and a second air outlet both communicating with the chamber. The motor is disposed on the volute. The vent pipe communicates with the second air outlet.

What is claimed is: 
     
         1 . A vent pipe, comprising:
 1) a top plate;   2) two side plates;   3) a base plate;   4) an air channel formed by the top plate, the two side plates, and the base plate, and the air channel comprising a first air inlet and a first air outlet; and   5) an air deflector disposed on the base plate and located on one side of the first air outlet.   
     
     
         2 . The vent pipe of  claim 1 , wherein the air deflector is perpendicular to the base plate. 
     
     
         3 . The vent pipe of  claim 2 , wherein one end of the base plate extends out of the air channel to form an extension plate, and the air deflector is disposed on the extension plate. 
     
     
         4 . The vent pipe of  claim 2 , wherein the air deflector is disposed in the air channel. 
     
     
         5 . The vent pipe of  claim 1 , wherein the two side plates are integrated with the top plate. 
     
     
         6 . The vent pipe of  claim 2 , wherein the two side plates are integrated with the top plate. 
     
     
         7 . The vent pipe of  claim 3 , wherein the two side plates are integrated with the top plate. 
     
     
         8 . The vent pipe of  claim 4 , wherein the two side plates are integrated with the top plate. 
     
     
         9 . The vent pipe of  claim 5 , wherein lower ends of the two side plates bend away from the air channel to form convex flanges; two sides of the base plate extend to form clamping units; and the convex flanges are clamped by the clamping units. 
     
     
         10 . The vent pipe of  claim 6 , wherein lower ends of the two side plates bend away from the air channel to form convex flanges; two sides of the base plate extend to form clamping units; and the convex flanges are clamped by the clamping units. 
     
     
         11 . The vent pipe of  claim 7 , wherein lower ends of the two side plates bend away from the air channel to form convex flanges; two sides of the base plate extend to form clamping units; and the convex flanges are clamped by the clamping units. 
     
     
         12 . The vent pipe of  claim 8 , wherein lower ends of the two side plates bend away from the air channel to form convex flanges; two sides of the base plate extend to form clamping units; and the convex flanges are clamped by the clamping units. 
     
     
         13 . The vent pipe of  claim 9 , wherein the air channel is rectangular in shape. 
     
     
         14 . The vent pipe of  claim 10 , wherein the air channel is rectangular in shape. 
     
     
         15 . The vent pipe of  claim 11 , wherein the air channel is rectangular in shape. 
     
     
         16 . The vent pipe of  claim 12 , wherein the air channel is rectangular in shape. 
     
     
         17 . A blower, comprising:
 a motor;   a volute;   a blade wheel; and   a vent pipe of  claim 1 ;   
       wherein:
 the volute comprises a chamber and the blade wheel is disposed in the chamber; 
 the volute comprises a second air inlet and a second air outlet both communicating with the chamber; 
 the motor is disposed on the volute; and 
 the vent pipe communicates with the second air outlet. 
 
     
     
         18 . The blower of  claim 17 , wherein:
 the volute comprises a top surface provided with a plurality of mounting holes;   a mounting plate is fixed on the top surface via the plurality of mounting holes and comprises a through hole;   the motor is disposed on the mounting plate and comprises a revolving shaft;   a front end of the revolving shaft of the motor passes through the through hole of the mounting plate to connect to the blade wheel in the chamber.
