mounting plate to connect to the blade wheel in the chamber.
[0014] Advantages of the vent pipe and a blower comprising the same
as described in the disclosure are summarized as follows.
[0015] 1. The base plate of the vent pipe is provided with an air
deflector, so that the air volume and static pressure in the vent
pipe are adjustable.
[0016] 2. The air deflector is perpendicular to the base plate. The
design is cost-effective.
[0017] 3. The air deflector is disposed in the air channel or on an
extension plate of the base plate. The arrangement is flexible.
[0018] 4. The lower ends of the two side plates are bent away from

DETAILED DESCRIPTION
[0030] To further illustrate, embodiments detailing a vent pipe and
a blower comprising the same are described below. It should be
noted that the following embodiments are intended to describe and
not to limit the disclosure.
[0031] As shown in FIGS. 1-5, provided is a vent pipe comprising a
top plate 1; two side plates 2; and a base plate 3; and an air
channel 4 formed by the top plate 1, the two side plates 2, and the
base plate 3. The air channel 4 comprises a first air inlet 41 and
a first air outlet 42. The base plate 3 comprises an air deflector
31 disposed at the first air outlet 42.
[0032] The air deflector 31 is perpendicular to the base plate
3.
[0033] One end of the base plate 3 extends out of the air channel 4
to form an extension plate 32, and the air deflector 31 is disposed
on the extension plate 32.
[0034] The two side plates 2 are integrated with the top plate
1.
[0035] The lower ends of the two side plates 2 bend away from the
air channel to form convex flanges 21; two sides of the base plate
3 extend to form clamping units 33; and the convex flanges 21 are
clamped by the clamping units 33.
[0036] The air channel 4 is rectangular in shape.
[0037] Optionally, the air deflector 31 is disposed in the air
channel 4, as shown in FIG. 6.
[0038] As shown in FIGS. 7-11, a blower comprises a motor 5, a
volute 6, a blade wheel 7, and the aforesaid vent pipe. The volute
6 comprises a chamber 61 and the blade wheel 7 is disposed in the
chamber 61; the volute 6 comprises a second air inlet 62 and a
second air outlet 63 both communicating with the chamber 61; the
motor is disposed on the volute 6; and the vent pipe communicates
with the second air outlet 63. The vent pipe is integrated with the
volute or fixed on the volute via bolts. For example, the first air
inlet 41 of the vent pipe is provided with a first screw hole 8,
the second air outlet 63 of the volute 6 is provided with a second
screw hole 8, and the first air inlet 41 of the exhaust extension
pipe and the second air outlet 63 of the volute are tightly
connected by the bolts 9.
[0039] The volute 6 comprises a top surface provided with a
plurality of mounting holes 64; a mounting plate 65 is fixed on the
top surface via the plurality of mounting holes 64 and comprises a
through hole 66; the motor 5 is disposed on the mounting plate 65
and comprises a revolving shaft 51; the front end of the revolving
shaft 51 of the motor 5 passes through the through hole 66 of the
mounting plate 65 to connect to the blade wheel 7 in the chamber
61.
[0040] Working principle: the air channel 4 formed by the top plate
1, the two side plates 2, and the base plate 3 comprises the first
air inlet 41 and the first air outlet 42; the base plate 3
comprises the air deflector 31 disposed at the first air outlet 42;
the volute 6 comprises a second air inlet 62 and a second air
outlet 63, and the vent pipe communicates with the second air
outlet 63, so that the air volume and static pressure in the vent
pipe are adjustable. The air deflector 31 is perpendicular to the
base plate 3. The design is cost-effective. The air deflector 31 is
disposed in the air channel 4 or on an extension plate 32 of the
base plate 3, so it is flexible in arrangement. The lower ends of
the two side plates 2 bend away from the air channel to form convex
flanges 21; two sides of the base plate 3 extend to form clamping
units 33; and the convex flanges 21 are clamped by the clamping
units 33. The connection of the base plate 3 and the two side
plates 2 is reliable.
[0041] It will be obvious to those skilled in the art that changes
and modifications may be made, and therefore, the aim in the
appended claims is to cover all such changes and modifications.
