DETAILED DESCRIPTION
[0035] The following description of the preferred embodiments is merely
exemplary in nature
and is in no way intended to limit the scope of the invention hereinafter
claimed, its application, or
uses.
[0036] Fig. 1 to Fig. 3 depicts an example of a wearable blower. The blower
100 includes a fan
10, a drive unit or a motor 20, an air duct assembly 30 and a handle 40.
4
CA 2972042 2017-06-28
[0037] The air duct assembly 30 is used to generate airflow. In this example,
the fan 10 is an
axial fan 10.The fan 10 is attached to the drive unit or a motor 20 which
drives the fan 10 to rotate
about a central line or axis 11 with respect to the blower. The drive unit 20
may be an AC motor or
a DC motor or a combination of one or more AC motors and/or one or more DC
motors. More
specifically, the drive unit or motor 20 is a brushless motor. The air duct
assembly 30 includes at
least one duct housing with an air passage 34. The air passage 34 is provided
with an air inlet 311
and an air outlet 312. The handle 40 is operated by a user and attached to the
duct housing, and the
blower 100 may be referred to as a hand-held device. The fan 10 is disposed
within the air passage
34 of the duct assembly 30. In other words, the air passage 34 of the duct
assembly 30
accommodates the fan 10. In an example, the fan is coupled to the drive unit
or the motor 20, the
motor 20 is also included within the air passage 34 of the duct assembly 30.
Further, the motor 20
is located between the fan 10 and the outlet 311.
[0038] The fan 10 rotates by the motor so as to drive the air flow from the
air inlet 321 to the air
outlet 311 through the air passage 34. As shown in the illustrated example of
Fig. 2 and Fig. 3, the
duct assembly 30 includes an inlet duct 32, an outlet duct 31, and a
connecting duct 33 connected
therebetween. The outlet duct 31 is formed with the air outlet 311, and the
inlet duct 32 is formed
with the air inlet 321. The connecting duct 33 is a configuration of two parts
including a first
connecting duct part 331 and a second connecting duct part 332. The air
passage 34 is a
substantially linear passage which extends along a central axis 11 of the
blowers with the air inlet
321, the fan 10 and the air outlet 311 arranged in a straight line. The outlet
duct 31 is detachably
connected to the connecting duct 33 so that the user can disassemble the
outlet duct 31 from the
blower 100 when not used in order to reduce the area occupied by the blower
100.
[0039] In Fig. 3 and Fig. 4, the handle 40 is located between the air inlet
321 and the air outlet
311 along the central axis of the blower, and disposed at a location proximate
to a center of gravity
of the blower during the operation thereof for the user to grip or hold the
handle 40 to more
comfortably. The motor 20 is located between two opposite ends of the handle
40 which attaches
to the duct 30, and has its weight force which also acts on the duct 30
between the two handle ends.
CA 2972042 2017-06-28
In this example, the blower includes a first buffer 41 and a second buffer 42,
and the handle 40 has
the two ends respectively attached to the duct housing 30 by the first buffer
41 and the second
buffer 42. The first buffer 41 or the second buffer 42 has some elasticity,
and is made of materials
which may include a rubber material. The first buffer 41 and the second buffer
42 are located at
two opposite ends of the motor or the handle 40.
[0040] The blower 100 includes a trigger 43 for allowing the user to control
the blower 100 by
the trigger 43. Specifically, the trigger 43 controls a start switch 47 which
electrically couples to
the motor 20, so that the control of the motor 20 is achieved by operating or
pushing the trigger 43.
In this embodiment, the user operates the trigger 43 not only to control the
starting and stopping of
the motor 20 but also to control the rotational speed of the motor 20. The
start switch 47 is
disposed within a handle housing of the handle 40. In addition, the blower 100
also includes a lock
switch 44 which prevents the blower 100 from being erroneously activated.
Specifically, the lock
switch 44 is used to lock the trigger 43, and the trigger 43 cannot be
triggered when the lock switch
44 is turned on or at the locked state.
[0041] Further, the blower 100 includes an amplifier button 45 which enables
the blower 100 to
operate at a maximum power, so that heavier things, such as debris, can be
blown away. The user
can release the amplifier button 45 so that the motor 20 is operated at a
predetermined speed
determined by the trigger 43 when the blower is not required to operate at a
higher power. The
amplifier button 45 controls the amplification switch 46, which electrically
connects to the motor
20 and the amplification switch 46 is triggered by the outer amplifier button
45 so that the blower
100 can operate at maximum power. The amplification switch 46 is disposed
within the handle
housing of the handle 40. The user holds the handle 40 by one hand, and can
operate the amplifier
button 45 and the trigger 43 by using one hand at the same time when the
handle 40 is held by the
user.
[0042] The air duct 30 is formed with at least one chamber for accommodating a
PCB board or
circuit board 35, or the circuit board 35 is located within the chamber. In
the direction of the
6
CA 2972042 2017-06-28
central axis 11 of the blower, the circuit board 35 is located between the air
inlet 321 and the air
outlet 311. Specifically, the circuit board 35 is located between the motor 20
and the air inlet 321
or behind the handle 40, while the motor 20 is located between the air outlet
311 and the circuit
board 35.
[0043] In Fig. 2 and Fig. 3, the handle is attached to the duct housing and
disposed at a location
between the inlet and the outlet along the central axis direction of the
blower. The hand-guided
blower or work apparatus comprises an arm support 50 for supporting the
operator's arm except
for the handle 40. That is, the blower includes an arm holder or support 50
which, when the user
holds the handle 40, supports the user's arm between the handle 40 and the air
inlet 321. Thus, the
user can operate the blower with one hand for a long time without fatigue. The
arm support 50 has
a support surface 51, which is more adjacent to the inlet 321 than the outlet
311 along the central
axis direction and set to be in contact with an arm of the operator when the
handle 40 is held by the
operator. Further, the arm support 50 is located behind the handle 40 and more
adjacent to the inlet
321 or between the handle 40 and the inlet 321. In Fig. 3, the PCB board 35 is
located between the
support surface 51 and the air duct 34.
[0044] In Fig. 5 to Fig. 7, the support surface 51 is of a curved shape
suitable to be in contact with
the user's arm, and has a middle part with opposite support side-edges, which
are bent more away
from the blower than the middle part of the support surface 51. In Fig. 4, the
support surface 51 of
the arm support 50 has a front support end and a rear support end, the front
support end near the
outlet 311 is located more adjacent to a central axis of the blower than the
rear support end near the
inlet 321. Thus, the operator can use the arm support more comfortably because
of the tilted arm
support during the operation thereof The trigger or button 43, 44, 45 for at
least controlling the
operation of the drive unit 20 is located at a position between the central
axis line of the blower and
the support surface 51 of the arm support 50.
[0045] In Fig. 4, the blower includes a support attachment 52 for attaching
the arm support 50 to
the duct housing. The support attachment 52 has elasticity to allow the
movement of the arm
7
CA 2972042 2017-06-28
. ,
support 50 relative to the duct housing.
[0046] The arm support 50 has an upper portion, made of soft material, near
the side of the arm,
to provide a cushion for the arm support 50, which may be of hard material.
The arm support 50
can entirely use the soft material, or at least partly use the soft material.
Specifically, the arm
support 50 can be made of material layers including a soft material layer and
a hard material layer,
or combination of soft material and hard material layers. The soft material
layer or layers of the
arm support 50 can be employed to be in contact with the user's arm for
comfortable consideration.
[0047] In a preferred embodiment, the blower includes a support attachment 52
for attaching the
arm support 50 to the duct housing 30. The support attachment 52 has
elasticity to allow
movement of the arm support 50 relative to the duct housing 30. The arm
support 50 is movably
and removably attached to the air duct 30 by the support attachment 52.
[0048] As shown in Fig. 3 and Fig. 4, the blower 100 includes a cable 70 that
leads from the
motor 20 or the circuit board 35 to an outer power supply. The cable 70 of the
power supply is
attached to the duct housing 30 by a cable attachment. The circuit board 35 is
located between the
handle and the cable attachment which is attached to the duct housing. The
circuit board 35 and
the handle 40 are located at the same side of the blower with the cable
attachment of the cable 70.
That is, the circuit board 35 is located behind the handle 40, or in front of
the cable attachment to
the cable 70. The handle 40 is located between the air outlet 311 and the
cable attachment of the
blower 30, and the cable 70 is disposed adjacent to the rear end of the blower
100.
100491 In Fig. 2 and Fig. 3, the blower 100 also includes a noise reduction
assembly for reducing
the noise of the blower 100 during the operation thereof, and the noise
reduction members are
provided in the air passage 34, and may be removably attached to the inner
wall of the air duct 30
forming the air passage 34. The noise reduction assembly includes a first
noise reduction member
36 and a second noise reduction member 37 respectively provided on front and
rear ends of the fan
along the direction of the air flow. The first noise reduction member 36 is
provided on the
upstream of the duct passage 34, while the second noise reduction member 37 is
provided on the
8
CA 2972042 2017-06-28
,
,
downstream of the duct passage 34. In detail, the first noise reduction member
36 is at least partly
provided between the fan 10 and the air outlet 311, while the second noise
reduction member 37 is
at least partly provided between the fan 10 and the air inlet 321.
[0050] The air duct 30 defines an inlet passage 341 for the inlet air and an
outlet passage 342 for
the outlet air. The inlet passage 341 is formed by an inlet duct 32, and the
air inlet duct 32 has one
end acts as an air inlet 321. More specifically, the inlet air passage 341 is
configured to extend
along the central axis of the blower, and gradually shrink from the air inlet
321 to the air outlet 311
along the flow direction of the air flow. That is, upper and down sides of the
passage 341 is set to
gradually shrink towards the central axis of the blower. The second noise
reduction member 37 is
disposed within the inlet passage 341 and removably attached to the inner wall
of the inlet duct 32.
[0051] The air outlet duct 31 and the connecting duct 33 forms the outlet
passage 342. The first
noise reduction member 36 is disposed within the outlet passage 342 and
removably attached to
the inner wall of the connecting duct 33. In another embodiment, the first
noise reduction member
36 may be disposed onto the inner wall of the outlet duct 31. The outlet
passage 342 and the inlet
passage 341 combine to form the whole passage 34.
[0052] The blower 100 also includes an isolation cover 38 which covers the air
inlet 321 and
prevents matter from entering the duct passage 34. The isolation cover 38 is
mounted to the
blower 30, and further can be removably attached to the inlet duct 32.
[0053] As shown in Fig. 3 and Fig. 7, in a cross-section plane perpendicular
to the central axis 11
of the blower, the inlet passage 341 is substantially of an elliptical shape
with a left-right
dimension of the inlet passage 341 along the left-right direction of the inlet
passage 341 being
greater than an up-down dimension of the inlet passage 341 along the up-down
direction of the
inlet passage 341. The handle 40 is symmetrical with respect to a plane, and a
maximum normal
size of the inlet passage 341 along a normal direction vertical to the plane
of the handle 40 is
greater than a maximum plane size of the inlet passage 341 along a direction
of the plane of the
handle 40.

CA 2972042 2017-06-28
[0054] As shown in Fig. 8, the air duct 30 includes an inlet portion or
section 322, and an outlet
portion or section 312. The inlet portion or section 322 is formed with the
air inlet 321, and the
outlet portion 312 is formed with the air outlet 311. Specially, the inlet
portion 322 is a part of the
inlet duct 32, and an outlet portion 312 is a part of the outlet duct 31.
[0055] The inlet section 322 of the air duct assembly 30 comprises a first
inlet part 324 and a
second inlet part 325 that intersects with each other, wherein the first inlet
part 324 is configured to
face downwardly and tilt relative to the central axis of the blower with a
first tilting angle 0 , and
the second inlet part 325 is configured to face upwardly and title relative to
the central axis of the
blower with a second tilting angle 6 which is greater than the first tilting
angle 13 , the first inlet
part 324 having a cover area greater than that of the second inlet part 325.
It should be noted that a
sum of the first tilting angle and the second tilting angle is greater than 90
degrees, which is set to
increase the amount of air into the blower from the outer.
[0056] Due to the inlet section 322 for the inlet 321 having two parts
including the first inlet part
324 and the second inlet part 325, problems of noise, and leaves or debris re-
entering into the air
duct 34 can be simultaneously and effectively solved. That is, because of the
first inlet part 324,
which is located above the central axis of the blower 100, being configured to
face downwardly
and extend rearwardly to enlarge the area of flow air, the flow air enters the
air duct 34 from below
and the noise can be effectively reduced due to the enlarged area of the flow
air, and the second
inlet part 325, which is located below the central axis of the blower 100,
being configured to face
upwardly and extend rearwardly, prevents the leaves or debris that are blown
by the blower 100
from re-entering into the air duct 34 from below during the operation thereof
[0057] In Fig. 7 and Fig. 8, the air duct assembly 30 defines a first
projection plane 101 which is
substantially perpendicular to a horizontal plane, a projection of the inlet
section 322 in the first
projection plane 100 defines as a first projection line 323, a highest point
of the first projection line
323 away from the center axis of the blower is the farthest point away from
the outlet section 312
in the first projection plane 101. Further, the first projection line 323 of
the inlet section 322 is
CA 2972042 2017-06-28
. .
bent in a direction towards the outlet section 312 of the blower. A highest
point of the first
projection line away from the center axis of the blower is located at a same
side of the central axis
of the blower with the handle in the first projection plane.
[0058] The first projection line 323 includes a first projection line part 324
and a second
projection line part 325, both of which tilt relative to the central axis line
of the blower. In this
embodiment of Fig. 3 to Fig. 4, the first projection line part 324 and/or the
second projection line
part 325 is a straight line, while in the other embodiments of Fig. 10 to Fig.
11, the first projection
line part 324 and/or the second projection line part 325 may be an arc line
3241, 3251 or 3242,
3252, a tangent line 3241a, 3241b, 3251a, 3251b, 3242a, 3252a of which is
inclined or tilts with
respect the central axis 11 of the blower. In Fig. 3, the first projection
line part 324 and the second
projection line part 325 are combined to have a V-shaped pattern 3231, 3232
which has a bent
point or part located more adjacent to the outlet 311 than any other points of
the V-shaped pattern
3231, 3232.
[0059] As shown in Fig. 7 and Fig. 9, the air duct assembly further defines a
second horizontal
projection plane perpendicular to a first projection plane, a projection of
the inlet section 322 in the
second projection plane defines as a second projection line 326, the second
projection line 326 of
the inlet section 322 is bent in a direction away from the outlet section 311
of the blower. In other
words, the inlet section 322 of the air duct assembly is bent in a direction
towards the outlet section
311 of the blower. Specifically, the inlet section 322 including the first
inlet part 324 and the
second inlet part 325 has a substantially middle portion, adjacent to the
central axis of the blower,
bent towards the outlet section 311 of the blower with the first inlet part
324 having the cover area
greater than that of the second inlet part 325.
[0060] The first inlet part 324 of the inlet section 322 is configured to face
downwardly and tilt
relative to the central axis of the blower with a first tilting angle 13 , and
the second inlet part 325 is
configured to face upwardly and tilt relative to the central axis of the
blower with a second tilting
angle 6 which is greater than the first tilting angle 13 , the first inlet
part 324 having a cover area
11
CA 2972042 2017-06-28
,
greater than that of the second inlet part 325. It should be noted that a sum
of the first tilting angle
and the second tilting angle is greater than 90 degrees, which is set to
increase the amount of air
into the blower from the outside.
[0061] In another example illustrated in Fig. 10, a first tangent line 3241a
of the first inlet part
324 tilts relative to the central axis of the blower with a first tilting
angle 131, and a first tangent
line 3251a of the second inlet part 325 tilts relative to the central axis of
the blower with a second
tilting angle 8 1, a sum of the first tilting angle 131 and the second tilting
angle 5 1 is greater than
90 degrees, wherein each of the first tilting angle 131 or the second tilting
angle 5 1 is an acute
angle.
,
[0062] A second tangent line 324 lb of the first inlet part 324 tilts relative
to the central axis of the
blower with a first tilting angle 13 2, and a second tangent line 325 lb of
the second inlet part 325
tilts relative to the central axis of the blower with a second tilting angle 5
2, a sum of the first
tilting angle 13 2 and the second tilting angle 8 2 is greater than 90 degrees
with the first tilting
angle f3 2 or the second tilting angle 5 2 being an acute angle. The sum of
the first tilting angle 13
1, f3 2 and the second tilting angle 8 1, 8 2 is greater than 90 degrees,
which increases the amount
of air into the blower from the outside, and simultaneously solves the
problems of noise and leaves
or debris re-entering into the air duct 34 by the first inlet part 324 and the
second inlet part 325.
[0063] In another example illustrated in Fig. 11, a third tangent line 3242a
of the first inlet part
324 tilts relative to the central axis of the blower with a first tilting
angle 13 3, and a third tangent
line 3252a of the second inlet part 325 tilts relative to the central axis of
the blower with a second
tilting angle 6 3, a sum of the first tilting angle 13 3 and the second
tilting angle 5 3 is greater than
90 degrees, and the first tilting angle 13 3 or the second tilting angle 6 3
is an acute angle. Thus,
the arrangement of the first inlet part 324 and the second inlet part 325 is
to solve the problems of
noise and leaves or debris re-entering into the air duct 34.
[0064] As shown in Fig.1 and Fig.12, the wearable blower is provided with a
hanger 60 disposed
on the duct housing. The hanger 60 includes an attachment part 62 rotatably

[0072] In a third example of the hanger of Fig. 19 and Fig. 20, the hanger
part 61b is coupled to
the air duct 302, and rotates with the air duct 302 about a rotation axis 63b,
which is substantially
parallel to the central axis of the air duct 302. Fig. 19 shows a first
hanging or work position of the
hanger part 61b, and Fig. 20 shows a second folded or work position of the
hanger part 61b. Note
that the hanger can provide at least two work positions varying in accordance
with the user's
different operating states in other examples of the present invention. For
example, the hanger can
rotate to a predetermined work position along with the rotation of the blower
when the user
laterally holds the blower to work.
[0073] In a fourth example of the hanger of Fig. 21 and Fig. 22, the hanger
part 61c is movably
coupled to the air duct 303, and rotates with the air duct 302 about a
rotation axis 63c which is
substantially perpendicular to the central axis 114 and through the air duct
303, or a horizontal
plane of the blower. The first hanging position of the hanger part 61c is
shown in Fig. 21, and the
second folded position of the hanger part 61c is shown in Fig. 22.
