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. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The vent pipe of claim 1, wherein the air deflector is perpendicular to the base plate. ### Claim 3 (depends on 2) 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. ### Claim 4 (depends on 2) The vent pipe of claim 2, wherein the air deflector is disposed in the air channel. ### Claim 5 (depends on 1) The vent pipe of claim 1, wherein the two side plates are integrated with the top plate. ### Claim 6 (depends on 2) The vent pipe of claim 2, wherein the two side plates are integrated with the top plate. ### Claim 7 (depends on 3) The vent pipe of claim 3, wherein the two side plates are integrated with the top plate. ### Claim 8 (depends on 4) The vent pipe of claim 4, wherein the two side plates are integrated with the top plate. ### Claim 9 (depends on 5) 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. ### Claim 10 (depends on 6) 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. ### Claim 11 (depends on 7) 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. ### Claim 12 (depends on 8) 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. ### Claim 13 (depends on 9) The vent pipe of claim 9, wherein the air channel is rectangular in shape. ### Claim 14 (depends on 10) The vent pipe of claim 10, wherein the air channel is rectangular in shape. ### Claim 15 (depends on 11) The vent pipe of claim 11, wherein the air channel is rectangular in shape. ### Claim 16 (depends on 12) The vent pipe of claim 12, wherein the air channel is rectangular in shape. ### Claim 17 (depends on 1) 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. ### Claim 18 (depends on 17) 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.
