of the present disclosure will be described with reference to FIG.
1 to FIG. 4.
[0028] As shown in FIG. 1 to FIG. 4, the ground brush 1 for the
vacuum cleaner according to the embodiments of the first aspect of
the present disclosure includes a ground brush body 10, a brushroll
cover 20, a brushroll assembly and a microswitch 40.
[0029] With reference to FIG. 1 and FIG. 3, the brushroll cover 20
is disposed on the ground brush body 10 in such a manner that the
brushroll cover 20 can be opened and closed. The brushroll cover 20
and the ground brush body 10 define a mounting space therebetween,
that is, the brushroll cover 20 can be closed on the ground brush
body 10 and form the mounting space through cooperation with the
ground brush body 10. The brushroll assembly is disposed in the
mounting space and provided with a control circuit. The brushroll
cover is provided with a triggering part 203 that is configured to
cooperate with the microswitch 40.
[0030] The microswitch 40 is disposed on the ground brush body 10,
electrically connected with the control circuit of the brushroll
assembly, and configured to control the control circuit to be
turned on or off. The microswitch 40 is disposed on the ground
brush body 10, and the triggering part 203 triggers the microswitch
40 to turn on the control circuit when the brushroll cover 20 is
closed on the ground brush body 10, and the triggering part 203
releases a trigger action on the microswitch 40 to turn off the
control circuit when the brushroll cover 20 is opened.
[0031] In the ground brush 1 according to the embodiments of the
present disclosure, the triggering part 203 is disposed on the
brushroll cover 20 and cooperates with the microswitch 40. When the
brushroll cover 20 is closed, the triggering part 203 can trigger
the microswitch 40 directly or indirectly to make the brushroll 301
work normally, and when the brushroll cover 20 is opened, the
triggering part 203 can release the trigger action on the
microswitch 40 to make the brushroll 301 stop working, thus
avoiding accidental injury to a user caused by the brushroll 301 if
the user opens the brushroll cover 20 by mistake, and improving
safety and market competitiveness of a product.
[0032] Specifically, the overall brushroll cover 20 can be
rotatably connected with the ground brush body 10, and closed or
opened through turnover; or the brushroll cover 20 and the ground
brush body 10 can be connected in a snapping manner or an inserting
manner, that is the brushroll cover 20 can be closed or opened
through mounting or dismounting--the overall brushroll cover 20 can
be closed on the ground brush body 10, or separate from the ground
brush body 10 to be opened.
[0033] In some embodiments of the present disclosure, as shown in
FIG. 1 and FIG. 3, the brushroll cover 20 includes a cover body 201
and a connecting part. The cover body 201 cooperates with the
ground brush body 10 to form the mounting space, and the connecting
part is connected between the cover body 201 and the ground brush
body 10 to make the cover body 201 connected to the ground brush
body 10. The triggering part 203 is disposed on any one of the
cover body 201 and the connecting part, that is, the triggering
part 203 may be disposed on the cover body 201 or disposed on the
connecting part.
[0034] In the above embodiments, the brushroll cover 20 includes
the cover body 201 and the connecting part, and the cover body 201
cooperates with the ground brush body 10 to form the mounting space
to cover the brushroll 301, thus avoiding injury to the user when
the brushroll 301 works, and improving safety of the ground brush
1. The brushroll assembly located in the mounting space may be
mounted on the cover body 201 or mounted on the ground brush body
10, and preferably, the brushroll assembly is mounted on the ground
brush body 10, which is simpler in structure and more convenient to
assemble. The connecting part is connected with the cover body 201
and cooperates with the ground brush body 10, and the connecting
part is configured to fix the cover body 201 to the ground brush
body 10, thus preventing the brushroll cover 20 from separating
from the ground brush body 10 and further improving the safety of
the ground brush 1.
[0035] In some embodiments of the present disclosure, as shown in
FIG. 1 to FIG. 4, the connecting part includes a rotating shaft
202, the cover body 201 is rotatingly closed on the ground brush
body 10 through the rotating shaft 202, the triggering part 203 is
disposed on the rotating shaft 202, and the rotating shaft 202
rotates to make the triggering part 203 trigger the microswitch 40
when the cover body 201 is closed.
[0036] In the embodiments, as to a scheme that the brushroll cover
20 is closed on and connected with the ground brush body 10 in a
rotating manner, when the brushroll cover 20 is closed on and
connected with the ground brush body 10 through rotation of the
rotating shaft 202, the triggering part 203 is disposed on the
rotating shaft 202. In this way, when the cover body is rotated to
be closed, the triggering part 203 also rotates along with the
rotating shaft 202 until the cover body 201 is fully closed on the
ground brush body 10, and the triggering part 203 also rotates
exactly to a position corresponding to the microswitch 40 and
triggers the microswitch 40, to turn on the control circuit of the
brushroll assembly, thus guaranteeing that the vacuum cleaner can
work normally. When the cover body 201 is rotated to be opened, the
triggering part 203 also rotates to separate from the microswitch
40, to turn off the control circuit of the brushroll assembly
timely, and the brushroll 301 stops working immediately, thus
avoiding accidental injury to the user caused by the brushroll 301
and improving the safety of the ground brush 1.
[0037] In some other embodiments of the present disclosure, the
connecting part includes the rotating shaft 202, the cover body 201
is closed on the ground brush body 10 through rotating of the
rotating shaft 202, the triggering part 203 is disposed on the
cover body 201, and the triggering part 203 triggers the
microswitch 40 when the cover body 201 is closed.
[0038] In the embodiments, the connecting part includes the
rotating shaft 202, that is the brushroll cover 20 is closed on and
connected with the ground brush body 10 in a rotating manner; the
triggering part 203 located at the cover body 201 will rotate along
with the cover body 201 until the cover body 201 is fully closed on
the ground brush body 10, and the triggering part 203 rotates
exactly to a position corresponding to the microswitch 40 and
triggers the microswitch to turn on the control circuit of the
brushroll assembly, thus guaranteeing that the vacuum cleaner can
work normally. When the cover body 201 is rotated to be opened, the
triggering part 203 also rotates to separate from the microswitch
40, to turn off the control circuit of the brushroll assembly
timely, and the brushroll 301 stops working immediately, thus
avoiding accidental injury to the user caused by the brushroll 301
and improving the safety of the ground brush 1.
[0039] In some more embodiments of the present disclosure, the
connecting part includes at least one of a snapping member and an
inserting member, through which the brushroll cover 20 is connected
to the ground brush body 10, and the triggering part 203 is
disposed on the cover body 201.
[0040] In the embodiments, the connecting part includes the
snapping member and/or the inserting member, that is, the brushroll
cover 20 is closed on and connected with the ground brush body 10
in a snapping manner or an inserting manner. Only when the cover
body 201 is closed on the ground brush body 10, can the triggering
part 203 located at the cover body 201 trigger the microswitch 40,
to turn on the control circuit of the brushroll assembly, such that
the vacuum cleaner can work normally. When the cover body 201 is
separated from the ground brush body 10, the triggering part 203 is
separated from the microswitch 40, such that the microswitch 40
returns, to turn off the control circuit of the brushroll assembly
timely, and the brushroll 301 stops working immediately, thus
avoiding accidental injury to the user caused by the brushroll 301
and improving the safety of the ground brush 1.
[0041] In some embodiments of the present disclosure, as shown in
FIG. 3 and FIG. 4, when the brushroll cover 20 is closed on the
ground brush body 10, the triggering part 203 directly contacts and
triggers the microswitch 40.
[0042] Further, as shown in FIG. 2 and FIG. 4, the microswitch 40
includes a fixing member 401, a resilient member 402 and a button
403. Specifically, the fixing member 401 is fixed to the ground
brush body 10 and connected in the control circuit, the resilient
member 402 is disposed on the fixing member 401, the button 403 is
disposed on the fixing member 401, and the button 403 is located
between the resilient member 402 and the fixing member 401. The
triggering part 203 can turn on the control circuit if the
resilient member 402 presses the button 403, and when the
triggering part 203 is separated from the resilient member 402, the
button 403 returns to turn off the control circuit.
[0043] Furthermore, the resilient member 402 may be rotatably
disposed on the fixing member 401, when the brushroll cover 20 is
closed, the triggering part 203 triggers the resilient member 402,
such that the resilient member 402 rotates relative to the fixing
member 401 and presses the button 403, to turn on the control
circuit and enables the brushroll assembly to work normally. When
the brushroll cover 20 is opened, the triggering part 203 is
separated from the resilient member 402, the resilient member 402
returns to remove a pressure on the button 403, such that the
button 403 returns automatically to turn off the control circuit,
and the brushroll assembly stops working immediately, thus avoiding
accidental injury to the user. Certainly, the present disclosure is
not limited thereby; as shown in FIG. 2 and FIG. 4, the resilient
member 402 may include a fixing part 4021 and a resilient part
4022. Specifically, the fixing part 4021 has a first end fixed to
the fixing member 401, the resilient part 4022 has a first end
connected with a second end of the fixing part 4021, and the
resilient part 4022 has a second end extending to the button 403.
Preferably, as shown in FIG. 2 and FIG. 4, the button 403 is close
to a first end of the resilient part 4022.
[0044] Optionally, as shown in FIG. 2 and FIG. 4, the resilient
member 402 is configured as an L-shaped resilient sheet.
[0045] In the above embodiments, the microswitch 40 includes the
fixing member 401, the resilient member 402 and the button 403, and
the fixing member 401 is coupled with the control circuit of the
brushroll assembly. The button 403 can turn on or turn off the
control circuit, the control circuit is turned off at a natural
state; when the button 403 is pressed, the control circuit is
turned on; and when the pressure is removed, the button returns
automatically. The resilient member 402 is configured to press the
button 403. Specifically, when the brushroll cover 20 is closed,
the triggering part 203 applies the pressure on the resilient
member 402, and the resilient member 402 deforms resiliently to
press the button 403, so as to turn on the control circuit and
enable the brushroll assembly to work normally. When the brushroll
cover 20 is opened, the triggering part 203 is separated from the
resilient member 402, the resilient member 402 returns to remove
the pressure on the button 403, so the button 403 returns
automatically to turn off the control circuit, and the brushroll
assembly stops working, thus avoiding accidental injury to the
user.
[0046] Certainly, those skilled in the art should understand that
the microswitch 40 is not limited to the above structure, and it
may be configured as a small button 403 or other structures, as
long as having a function like that of the microswitch 40, so those
technical schemes are within the scope of the present
disclosure.
[0047] The resilient member 402 includes the fixing part 4021 and
the resilient part 4022, the fixing part 4021 can fix the resilient
member 402 to the fixing member 401, thus avoiding displacement of
the resilient member 402 and guaranteeing usage reliability of the
microswitch 40. The resilient part 4022 is resilient and can deform
resiliently to apply a pressing force on the button 403, such that
the button 403 can turn on the control circuit. A distance between
the resilient member 4022 and a surface of the fixing part 402 is
no less than a height of the button 403 at the natural state, thus
guaranteeing that the button 403 is located between the resilient
member 402 and the fixing member 401.
[0048] The button 403 is disposed closed to the first end of the
resilient part 4022 connected with the fixing part 4021, and a
second end of the resilient part 4022 is relatively far away from
the button 403. As to the scheme that the brushroll cover 20 is
rotatingly closed, only when the brushroll cover 20 is fully closed
on the ground brush body 10, can the resilient part 4022 press the
button 403 to a positon where the control circuit is turned on. In
the process of rotatingly closing the brushroll cover 20, the
button 403 cannot turn on the control circuit, thus avoiding that
the brushroll starts working when the brushroll cover 20 is not
fully closed, and further improving the safety of the product.
[0049] In other embodiments of the present disclosure, the ground
brush 1 further includes a driving member which is disposed on the
ground brush body 10 and cooperates with the microswitch 40. When
the brushroll cover 20 is closed on the ground brush body 10, the
triggering part 203 triggers the driving member and triggers the
microswitch 40 indirectly through the driving member.
[0050] In the above embodiments, the triggering part 203 triggers
the microswitch 40 through the driving member, that is when the
brushroll cover 20 is closed on the ground brush body 10, the
microswitch 40 is not directly but indirectly triggered, which can
also accomplish the objective of the present disclosure.
Specifically, when the brushroll cover 20 is closed, the triggering
part 203 triggers the driving member to apply an acting force on
the driving member, such that the driving member moves to trigger
the microswitch 40, so as to turn on the control circuit. When the
brushroll cover 20 is opened, the triggering part 203 is separated
from the driving member, the acting force applied on the driving
member is removed, so an acting force on the microswitch 40 applied
by the driving member is removed, the microswitch 40 returns to
turn off the control circuit.
[0051] A vacuum cleaner according to an embodiment of a second
aspect of the present disclosure includes the ground brush 1
according to the embodiments of the first aspect of the present
disclosure.
[0052] Specifically, when the brushroll cover 20 is closed, the
triggering part 203 may trigger the microswitch 40 directly or
indirectly, to turn on the control circuit of the brushroll
assembly, and a driving component drives the brushroll 301 to
rotate, such that the brushroll 301 works normally. When the
brushroll cover 20 is opened, the triggering part 203 can release a
trigger action thereof, the microswitch 40 returns to turn off the
control circuit of the brushroll assembly, the driving component
stops working, to make the brushroll 301 stop rotating, thus
avoiding injury to the user.
[0053] It is should be noted that those skilled in the art should
understand that the triggering part 203 may be configured as a
component individually disposed on the brushroll cover 20 or a part
of the brushroll cover 20, both of which can accomplish the
function of the microswitch 40 and fall into the scope of the
present disclosure.
[0054] As the vacuum cleaner according to the embodiments of the
present disclosure is provided with the ground brush 1 according to
the embodiments of the first aspect, the vacuum cleaner has high
