Description
Technical field
The present invention relates to a kind of suction nozzle with battery unit, can be used on vacuum cleaner.
The present invention is not limited to the suction nozzle with battery unit for any certain types of vacuum cleaner.For example, it be included in it is vertical true
Cleaner head in vacuum cleaner and the ground instrument on cylinder vacuum cleaner or hand-held vacuum cleaner.
Background technique
Some known vacuum cleaners include Stirring device, such as brush bar, and rotation is driven by motor.In order to reduce this
The risk of a motor overheating, some such vacuum cleaners include cooling path, and air stream is aspirated through the cooling path.
Air stream absorbs heat from motor to cool down it.However, (such as gear, motor pass through tooth to other component in some cases
Wheel drive blender) also it is easy overheat.Even if having, the cooling path of existing vacuum cleaner may not be able to be sufficiently cool these
Component, and/or cool down these components but need to pay the cost that cannot be fully cooled motor.Moreover, in some cases, air
Stream only absorbs heat from motor in the relatively short time, limits the amount of absorbed heat and motor is thus placed in overheat
Risk.
Summary of the invention
It is an object of the invention to which disadvantages mentioned above is mitigated or eliminated, and/or provides and improve or substitute suction nozzle with battery unit or vacuum cleaning
Device.
According to the first aspect of the present invention, a kind of suction nozzle with battery unit for vacuum cleaner is provided, which includes:
Limit longitudinal axis and can be around the blender that longitudinal axis rotates；
It is configured as the motor of Stirring device；And
The cooling path of outlet is extended to from entrance,
It wherein cools down path to be configured as guiding air stream from entrance, by motor and then passes over or across motor, arrive
Outlet.
This allows the other component of the cooling suction nozzle with battery unit of air stream, while being also fully cooled motor.As an example, cooling road
Diameter can before air stream travels through motor, during air stream travels through motor and/or air stream travel through motor it
Positioning air stream is adjacent to blender afterwards.Air stream can thus cooling and stirring device, and then travel over or pass through motor, thus
Cooling motor.In contrast, it if air stream travels over or passes through motor, then advances adjacent to blender, air stream will be compared with
With lacking degree cooling and stirring device (or even heating stirrer), because air stream is significantly heated by motor.If air stream
Motor and neighbouring blender are travelled through, but does not flow across then or passes through motor, motor may not be sufficiently cooled and can
Thus it overheats.
On the contrary or similarly, air stream travels through motor and then passes over or across motor and can increase air stream and is exposed to
From the time of the heat of motor, to increase the cooling effect provided by air stream to motor.For example, in the examples described above, when
Air stream travels through the first amount of the absorbable heat from motor of motor Airflow, and ought then flow across or pass through electricity
The second amount from the heat of motor is absorbed when machine.If on the contrary air stream only travel over or pass through motor, the first of heat
Measuring will remain in motor and possibly facilitates overheat.
Air stream is preferably guided through motor after being directed over motor, rather than crosses motor.This can increase
Can be by the total amount of the heat of absorbed, and/or the component of motor is allowed (to become the (such as commutation brush) or special of extreme heat
(such as insulated part between coil) is not encroached on vulnerable to overheat) more effectively it is cooled.However, in some embodiments enough
Heat motor travelled over by air stream removed from motor.
Refer to that air stream is guided ' to pass through ' motor intention and refers to that air stream is directed to pass the outside of motor, no matter air
Whether contacted with motor.Refer to that air stream is guided ' crossing ' motor intention and refers to that air stream is directed to pass the outside of motor,
It is contacted simultaneously with motor.Refer to that air stream is guided ' passing through ' motor intention and refers to that air stream is directed to pass the inside of motor.
Cooling path can be configured so that when air stream is directed over motor, and air stream can absorb heat from motor.
Alternatively, air stream can be spaced apart (when guiding air stream to pass through motor) by cooling path from motor, so as to work as air stream quilt
It is directed through motor Airflow and absorbs inappreciable heat from motor.
Cooling path can be configured to prevent air streams contact blender.
This can avoid for providing dynamic sealing (its can for production relatively complex and costly) to prevent air stream from cold
But the needs of path leakage.
When air stream is directed over motor, cooling path can be configured to prevent air streams contact motor.
The air when air stream is by motor can be reduced when air stream is directed over motor Airflow and does not contact motor
Flow the amount for the heat collected from motor.Air stream can be thus colder after by motor, so that air stream provides the cold of reinforcement
But the other component of suction nozzle with battery unit is arrived.
Motor can be at least partially received on the inside of blender.
For example, at least the 50% of total axial length of motor or at least 75% can be positioned on the inside of blender.Preferably,
Motor is fully received on the inside of brush bar.
Motor, which is at least partially received on the inside of brush bar, can provide advantageously compact Layout (compared to blender and motor quilt
The arrangement respectively accommodated).It is 44 at least partially received in the arrangement in blender in motor, less space may be provided on
Around motor.The problem of motor overheating can be thus more serious, and it can be particularly advantageous for thus applying the present invention to such arrangement
's.
Cooling path can be configured to guidance air stream between motor and blender by motor.
This allows to pass through motor Airflow cooling and stirring device when air stream.As usual, blender is not particularly vulnerable to heat
Amount infringement, however, blender is usually placed in a manner of allowing it to be touched by user.Thus blender cools down in this way
It is advantageous in secure context.
Selectively:
Suction nozzle with battery unit further includes two substantially concentric sleeves；
Sleeve is 44 at least partially received on the inside of blender；
Motor is 44 at least partially received on the inside of sleeve；And
Cooling path is configured so that air stream travels through motor between two sleeves, and in described two sleeves
Travel over or pass through motor.
This prevents air streams contact blender and contact motor while warp of advancing with cylindrical central sleeve in a manner of advantageous simple
It is crossed, while air stream being allowed to travel over or pass through motor.
Suction nozzle with battery unit may also include gear assembly, and motor can be by gear assembly Stirring device, and cooling path can also quilt
It is configured to guidance air stream and passes over or across said gear component.
Gear assembly can be subjected to great heating, because of the friction between meshing gear.Air stream is directed over or passes through
Gear assembly so that gear assembly is cooled can be thus particularly advantageous.
In the case where air stream is guided through gear assembly rather than crosses it, this can provide gear assembly and especially adds
Strong cooling.However, in the case where air stream is directed over this class component rather than passes through it, it may be advantageous to reduce air
Stream collects the abrasion particle of gear assembly and deposits them on motor a possibility that (it can damage motor).
Selectively:
Gear assembly is planetary gear train comprising central gear, the one or more planetary gears being installed on frame,
And rim gear wheel；And
Cooling path is configured as the rim gear wheel that guidance air stream crosses gear assembly.
Air stream be directed over rim gear wheel can provide gear assembly cooling maximization and air stream collect abrasion grain
Son minimum between optimal compromise-air streams contact gear assembly gear in one and can thus provide preferably it is cold
But, and not on the inside of rim gear wheel (wherein abrasion particle can accumulate) is flowed.
Cooling path can be configured to the guidance air stream before guidance air flowing passes over or across motor and cross or wear
Cross gear assembly.
Air stream travels over or is passed through before traveling passes over or across motor gear assembly and allows two component circles
It is completely cooling.In contrast, if air stream travels over before traveling passes over or across gear assembly or pass through motor, tooth
Wheel assembly may not be sufficiently cool (or being even heated), because the air stream from motor is too hot.
Cooling path can be configured to guidance air stream and enter blender in the axial end portion of blender, and identical
Blender is discharged in axial end portion.
Air stream can reduce another axial end for being located in blender in same axial end inlet and outlet blender
The quantity of design constraint in portion.For example, the end to axial of blender can be engaged by motor (or is connected drivably to it
Component) and/or by suction nozzle with battery unit shell rotate support, must also be accommodated caused by a part in cooling path without any
Complexity.
Cooling path can be configured at least 50% traveling of the axial length for guiding the air stream along blender.Example
Such as, cooling path can be configured at least 60% or at least 70% row of the axial length for guiding above-mentioned air stream along blender
Into.
This can increase the ratio that blender is cooled by air flow, and/or increase air stream adjacent to blender and can be from that
Receive the time quantum of heat.
Entrance can be configured so as to be derived from the outside of suction nozzle with battery unit into entrance with forming the air of air stream.
This might mean that compared to air, into entrance, (wherein foul can be entrained in it to air stream on the inside of suction nozzle with battery unit
In) arrangement more clean.Foul can then block cooling path and/or be accumulated on component (such as motor) and influence its property
Energy.
Entrance is preferably positioned in the upper area of suction nozzle with battery unit.The cloth being positioned in compared to entrance at lower area
It sets, this, which can be reduced, rests on a possibility that foul in surface to be treated is entrained into the air of entrance.
Blender can be brush bar, be configured for the fiber of stirring carpet surface to discharge foul from that.As one
A substitution, blender can be poliss.It is substituted as one, blender can be rotary mop.
Cooling path may include annular cross section channel (its direction of motion is flowed through relative to air).
This allows the cooling effect of the air stream across cooling path to be more evenly distributed.
Annular cross section can be positioned as the longitudinal axis circumferentially about blender, and/or circumferentially about the one of motor
Partially (and/or a part of gear assembly, in case of presence).
Annular cross section channel can be single circular passage or the annular array of discrete flow channel.
In the case where suction nozzle with battery unit includes substantially concentric sleeve as described above, annular cross section channel can be set
Between two sleeves.
Motor can be mounted to an end of suction nozzle with battery unit, and blender is engaged at the opposed end of suction nozzle with battery unit.
Blender can be removed from suction nozzle with battery unit.
This may make blender is more cleaned or maintained to be easier (for example removing the hair wound around it), and allow user
Shabby or damage blender is replaced in the case where not replacing entire suction nozzle with battery unit.
Blender can preferably be removed by the hole of its axial end portion.Suction nozzle with battery unit can have end cover, be used to select
Close hole to property.

Interior pipeline 104 forms outlet, and cooling Route guiding air stream is by motor and then across motor.Cooling path extends through
Exhaust outlet 108 is crossed, entrance cavity 106 is passed through and enters inflow chamber 109, and enter the gap 128 between sleeve 116,118.Air stream
Then the gap 128 axially between sleeve is directed over motor.Air is then out gap 128, crosses gear assembly
36 and pass through sleeve 116,118 in motor 34.Its then inflow and outflow chamber 92, passes through L shape channel 98 and pipeline 104, and passes through
12 discharge suction nozzle with battery unit 6 of outlet.This will be described in more detail below.
When vacuum cleaner 2 is in use, suction generator reduces the pressure at outlet 12.This reduces suction chamber in turn
Pressure in 18 enters suction chamber 18 to be passed through the suction air of suction opening 22.Since pipeline 104 and outlet 12 are in fluid communication,
Pressure in pipeline is also reduced by.This (in this example, enters suction independently of across suction opening 22 for suction air flow
The air stream with foul air of chamber 18) pass through cooling path.Air stream passes through exhaust outlet 108 and enters cooling path and enter
Oral cavity 106 (it is limited by installation component 78 and containment member 83).Exhaust outlet 108 is positioned on the outer surface of suction nozzle with battery unit 6, and
Thus air stream is taken from the relative clean air on the outside of suction nozzle with battery unit.In contrast, if air stream is taken from suction chamber 18,
So carrying will proceed through cooling path in foul wherein, may block cooling path and/or damage motor.Exhaust outlet
108 are also positioned at the upper area of suction nozzle with battery unit 6, so as to by it from being opened by clean ground separation, and to reduce into
Enter the chance of the foul on the air stream entrainment surface of exhaust outlet 108.
From entrance cavity 106, air stream passes through hole 110 and is pumped into inflow chamber 90, and then passes through motor supports 72
Air inlet 130 in radial hole 96 and inner sleeve 116 enters gap 128.The sealing structure that air stream passes through engagement inner sleeve
Part 76 is prevented from leaking out the cooling path between inner sleeve 116 and motor adapter 74.In some cases, some air
Stream can leak out between inner sleeve 116 and motor supports 72, however any such air will be yet by containment member
124 are directed into gap 128.
Enter gap 128 once the air inlet 130 for passing through inner sleeve 116, air can be circumferentially about gap in ridge 134
It is flowed between outer sleeve 118.Air stream then axially flows between motor 34 and blender 24 along gap 128, wears
Motor is crossed both circumferentially to be distributed around it.When air flows through motor 34, it absorbs some heats from that and thus has pair
The cooling effect of motor.When air along gap 128 flow Airflow also from blender 24 absorb heat (and when air along flow into
Lesser degree absorbs heat when chamber 90 flows), it is ensured that blender keeps enough coolings and can be touched by user.
When air stream axially travels up to venthole 132 along gap 128, it is along total axial length of blender 24
About 70%, which advances, (flows into about the 20% of the length of the blender in chamber 90, and the pact of the length of the blender in gap 128
50%).This relatively large ratio means that the cooling of air stream influences to be undergone by the larger proportion part of blender 24.This is right
Be in the ratio of the axial length of blender 24 it is particularly useful, air travels across this of blender when in gap 128
The axial length of ratio, because Airflow is located proximate to blender in gap.
Once air stream reaches the venthole 132 of inner sleeve 116, (it is by covering in a part of rim gear wheel 44 for air stream
68 and gear adapter 48 arm 60 exposure) on run, and enter gear adapter gap 62.When air stream travels over
Rim gear wheel 44, it absorbs energy from that and thus cools down rim gear wheel 44 (and thus generally speaking gear assembly 36).Air passes through o
Shape ring 126 is prevented from going out from the cooling path leakage by the gas vent 132 between sleeve 116,118, and passes through o ring 122
It is stopped between inner sleeve 116 and gear adapter 48 and leaks out.Moreover, air is prevented from by o ring 66 from cooling
Path leakage goes out and enters the gear assembly between rim gear wheel 44 and motor housing 46, and by rim gear wheel, elastomeric cap 68 and interior
Sealing engagement between portion's sleeve 116 is stopped between inner sleeve 116 and rim gear wheel 44 and leaks out.
Since air stream is run between sleeve 116,118 by motor 34, when air stream is directed over motor it
It is prevented from contacting motor.Air stream is spaced apart by inner sleeve 116 from motor 34, and thus air is not at this point from motor
Absorption such as inner sleeve is not present and air stream can cross the so much heat of the heat crossed and absorbed when motor is advanced.When air reaches
It is thus colder to 36 Airflow of gear assembly, and thus can more cool down it.Though words so say that inner sleeve 116 conducts heat
It measures far from motor, and the significant proportion of this heat is by absorbed, thus when air stream is directed over 34 space-time of motor
Air-flow still has the cooling effect to motor 34.
Outer sleeve 118 (inflow chamber and outflow chamber 90,92 together with motor supports 72 are together) is positioned to prevent
Air streams contact blender.In contrast, if outer sleeve 118 be not present and the tubular portion 24a of blender 24 formed it is cold
But the wall of flow path, by that must provide dynamic sealing in each end of tubular portion, (for example one in tubular portion
Point between 24a and containment member 76 and another the end (its support frame 42) of tubular portion and inner sleeve 116 it
Between).Such dynamic sealing be it is substantially relatively expensive, need opposite close tolerance and abrasion be relatively rapid.
From the gap of gear adapter 48 62, air stream passes through the shell 46 that venthole 64 is advanced into motor 34, passes through hole
86 travel out motor and enter the inner space 84 of motor adapter 74.When air stream travels across motor 34, it is further
Heat is absorbed from motor, to provide the additional cooling effect for arriving that.
From the inner space 84 of motor adapter 74, air stream travels across the hole 88 in motor adapter, passes through sealing
The pipeline 115 of component 76 and the outflow chamber 92 for entering motor supports 72.It is cold between motor adapter 74 and containment member 76
But the air in path leaks through the engagement between containment member 76 and inner sleeve 116 and is prevented from by o ring 120.
Air in outflow chamber 92, which then passes through hole 101 and is aspirated into, to be limited by installation component 78 and containment member 82
L shape channel 98 radially extends arm 100.Air is then flowed along L shape channel 98, and into pipeline 104, (it forms cooling path
Outlet).Air stream is then converged with the band foul air flowed from suction chamber 18, and passes through 12 discharge suction nozzle with battery unit 6 of outlet.
It is worth noting that in this embodiment, the air stream across cooling path flows across gear assembly 36, and
Then pass through motor 34.This ensures that gear assembly is sufficiently cooled.If then air stream travels across motor 34 more on the contrary
Gear assembly 36 (its can seem at First view preferably to avoid gear assembly from the abrasion of particles for being pumped into motor) is crossed,
Air stream can be too hot for gear assembly when it reaches gear assembly, and cannot be fully cooled.
(hole 110 is passed through in an axial end portion it should also be noted that cooling down Route guiding air stream in this embodiment
With inflow chamber 90) enter blender 24, and blender is exited same axial end (passing through outflow chamber 92 and hole 101).This
So that the opposed end and association structure of blender and cooling path are required also to travel across the cloth of this end of blender
It sets compared to relatively easy.
