Vacuum cleaner is provided with a series of instruments that are used to handle specific cleaning type usually.Instrument comprises ground instrument, is used for clearing up on the general ground.The someone is devoted to improve ground instrument in the ground pickup capacity of carpeting.Some instruments have the brush of installing in suction inlet, described brush rotation is so that brush floor surface in the mode identical with the brush rod of upright vacuum cleaner.Brush can be by using air turbine or rotating the power supply that this motor obtains by automatically cleaning device main body by motor.But, the more expensive and power consumption than passive ground instrument usually of this class instrument.

The someone is devoted to improve ground instrument in more passive mode.For example, EP1320317 has disclosed a kind of ground instrument, has to be attached near the suction passage at least one side working edge, and this working edge is used for engaging and brush with floor surface and moves floor surface.Lint picker on the instrument bottom side is used as unilateral gate, is used for allowing when ground instrument is promoted along ground hair, fine hair and other fibrous materials process below lint picker, but stops velveteen when ground instrument is moved to pulling back.Ground instrument catching velveteen and it is balled up forward and to backhauling kinetic energy repeatedly on floor surface is so that it can be siphoned away by ground instrument.

The another kind of improvement is disclosed in GB 1,077, and in 574, it has disclosed a kind of instrument, and it has two inlet holes that separate, and has the width that the pipeline that places between the described hole and this pipeline stride across instrument and extends, and the open-ended of pipeline is to atmosphere.This instrument has provided good pickup capacity, but the air conduit that interference is set makes known overall dimension, particularly its attitude bigger than required.

Summary of the invention

The invention provides a kind of surface treating head, comprising: main body; Suction chamber in main body, this suction chamber comprises first and second suction passages, each suction passage is the border with the working edge at least one side; Outlet; Fluid flow path in suction chamber is between first and second passages and between second channel and the outlet; Brush unit; And driving mechanism, be used for mobile brush unit between deposit position and expanded position.

At GB1, in 077,574, fluid is set to side by side flow to outlet and flow to outlet from second suction passage from first suction passage, and two parallel flow paths need be set.On the contrary, provide from first suction passage to second suction passage and the fluid flow path of extending to outlet from second suction passage allows to make the more instrument of streamline.

For make surface treating head handle to carpet floor surface and hard ground surface the two, the driving mechanism that surface treating head is equipped with brush unit and is used to allow brush unit move between deposit position and expanded position.Brush unit preferably includes at least one brush, and it can comprise in row mane, mane curtain and at least one flexible strip of material at least one, and this brush extends around the main body of ground instrument at least in part.At the deposit position of brush unit, brush is preferably located in working edge top, surface treating head is in to be suitable for handling the structure of floor surface of carpeting thus.On the other hand, in the expanded position of brush unit, at least a portion of brush is preferably located in the working edge below.This makes surface treating head be in to be suitable for handling the structure on hard ground surface.

Second channel is preferably located between first passage and the outlet.Preferably, this head comprises air duct, and it opens into atmosphere and places between first and second suction passages.This allows air to suck in the both sides of two suction passages, can improve pickup capacity.Air duct preferably extends between the upper surface of main body and lower surface, so that air is drawn into the edge of suction passage downwards.

Advantageously, air duct flows so that produce the air of working edge surface near at least one working edge.This helps foul and dust that for example effect of the working edge on carpet fiber is stirred are drawn into suction chamber.

Preferably, each suction passage is the border with the relevant work edge on both sides, so that the agitaion of instrument increases.The further enhancing of stirring can be by extending at least one working edge, so that its whole width that occupies main body is substantially realized.

Advantageously, the part of fluid flow path forms by the center-aisle that extends between first suction passage and second suction passage.Fluid flow path preferred comprises first and second center-aisles, and it can extend transverse to suction passage, and is preferably located on the opposite side portion of tool body.

Preferably, fluid flow path comprises the zone that the streamwise area of section increases.Any of suction passage or the two can comprise the zone that the streamwise sectional area increases.This structure provides the balance of suction chamber internal pressure, is drawn into equably in these two suction passages so that air strides across the whole width of passage.

The basal surface of main body can be provided with at least one lint picker, and it helps picking up of hair, fine hair and other fibers.

Air delivery valve also can be provided with and be arranged as in use according to the pressure in the suction chamber (for example under pressure is fallen predetermined pressure time) and allow atmosphere to enter instrument.This prevent under the situation that suction chamber temporarily is plugged main body by to tenesmus on floor surface.

Flexible hose is preferably between outlet and connector, and this connector is used for instrument is connected to the push rod or the hose end of cartridge type (pot type, bucket formula), upright or hand-held vacuum cleaner.Alternatively, instrument can form the part of surface treating appliance itself, such as the cleaning head of upright vacuum cleaner or stick type vacuum cleaner.

Driving mechanism preferably is arranged as characteristic automatically mobile brush unit between deposit position and expanded position of the floor surface at place when in use being operated according to surface treating head.

The air pressure of preferably using driving mechanism realizes that brush unit has motion between deposit position and the expanded position at it.For example, driving mechanism can comprise pressure chamber and the device that is used for changing pressure chamber's pressure.Brush unit is arranged to according to the pressure in the chamber and moves between its deposit position and expanded position.Pressure chamber can have the volume that changes according to the difference between air pressure in the chamber and the chamber outside atmospheric pressure, and the change of pressure chamber's volume causes brush unit to move with respect to main body thus.

At least a portion of brush unit can be extended on the main body upper surface, and can be arranged as in brush unit at least a portion of brush unit when its deposit position moves to its expanded position can be with respect to the upper surface motion of main body, for example towards the upper surface motion of main body.For example, brush unit can be above the surface treatment head main body and the covering that extends on every side or the form of framework.The result, when brush unit during at its expanded position, the part of brush unit can be closed air duct, makes to form low pressure in suction chamber, and improves the foul and dust the drawing into to the air-flow that enters suction chamber that will be arranged in the hard ground surface gaps thus.

Pressure chamber is preferably located between main body and the brush unit.Pressure chamber is preferably located in main body top, and thus can be between the lower surface of the upper surface of main body and a brush unit part, and can be partly upper surface by main body limit.The lower surface of brush unit also can limit the part of pressure chamber, and alternatively the lower chambers section can be positioned on the main body outer surface, and brush unit comprises can be with respect to upper chamber's section of lower chambers section motion.Chamber can further comprise ring-shaped flexible seal member, and it extends between upper and lower chamber section, provides gas-tight seal simultaneously with the volume-variation of authorized pressure chamber between them.The sealing member is the form of sleeve, and this sleeve has an end that is connected to upper chamber's section and the other end that is connected to the lower chambers section.

Alternatively, a form that can be arranged as piston in lower chambers section and the upper chamber's section, this piston can be in another chamber section and with respect to this another chamber section motion, to change the volume of pressure chamber.In this case, O shape ring or other annular seal elements can be positioned on the inner most periphery surface of chamber section, to form gas-tight seal between the chamber section.

As another alternative, pressure chamber can be the form of capsule or other expandable members, and between main body and brush unit, and it can move to deposit position with brush unit from expanded position when it expands.

Chamber preferably takes up elastic component, such as spring, is used for chamber is actuated towards the structure that brush unit is in its deposit position.The pressure that reduces in the chamber can to reduce the volume of chamber, make brush unit move to its expanded position so that atmospheric pressure is resisted the biasing force of elastic component and acted on the chamber thus.Subsequently for example by allowing air to make flexible member increase the volume of chamber with the pressure that atmospheric pressure enters chamber and increases in the chamber, make brush unit move to its deposit position, be suitable for handling the structure of floor surface of carpeting so that surface treating head is in.

Suction chamber preferably forms the part of suction passage, this suction passage extends to the air outlet slit of surface treating head, and the device that is used for changing the chamber air pressure is preferably incorporated in the fluid line that extends between suction passage and the chamber and is used to control controlling organization by the air-flow of fluid line.Controlling organization preferably is arranged as in use according to these characteristics that are operated the floor surface at place and changes air-flow by fluid line, and changes the air pressure in the chamber thus.

Controlling organization comprises actuator, and this actuator can move with respect to main body, to change the air-flow by fluid line.When on surface treating head is being wanted processed surface, operating, actuator preferably be configured in use by with engaging of this surface with respect to the main body motion, preferably pivot with respect to main body.

Controlling organization can comprise at least one surface engagement member, and for example wheel or other rolling elements extend beyond actuator downwards.As a result, when surface engagement member and hard ground surface engagement, actuator and floor surface are spaced apart, and remain on its position thus on this floor surface when surface treating head is operated.As a result, keep relatively low pressure in chamber, this remains on brush unit in its expanded position when surface treating head is operated on the hard ground surface again.

When surface treating head when the hard ground apparent motion is on carpet surface, be trapped in the tuft of carpet to the near small part of ground engagement member, make actuator contact with floor surface.When operating on surface treating head is being carpeted floor surface, the tuft of floor surface makes actuator movements, for example moves to position of rotation.The motion of actuator impels the pressure in the chamber to raise, and makes flexible member that chamber is moved to expansion structure and thus brush unit moved to its deposit position, makes working edge contact with the floor surface of carpeting thus.

Controlling organization can comprise fluid flow port, and this fluid flow port is exposed to atmosphere and is communicated with the fluid line fluid, also comprises valve, is used for optionally closing fluid flow port, and actuator arrangement is this valve of operation.Valve preferably moves between the primary importance and the second place, is exposed to atmosphere at this primary importance fluid line, in this second place, and the basic and atmospheric isolation of fluid line.Actuator preferably is in the position bias voltage of the second place towards valve.

opposite flank

26,28 of the main body 12 of ground instrument 10.First suction passage 22 is positioned near the antetheca 30 of ground instrument 10, and second suction passage 24 is positioned near the rear wall 32 of ground instrument 10.First and

second suction passages

22,24 have similar substantially external dimensions and are arranged in same plane.Second suction passage 24 is open to the outlet 34 of rear wall 32 middle positions that are arranged in main body 12.Center-aisle 36 provides the fluid between first suction passage 22 and second suction passage 24 to connect.Two center-aisles 36 are set, and each is positioned near the

respective side edges

26,28 of main body 12.Center-aisle 36 horizontal expansion between suction passage 22,24.The lateral wall of center-aisle 36 comprises the part of the

lateral edges

26,28 of ground instrument 10.

Each

suction passage

22,24 limits by the working edge that the basal surface 18 by ground instrument 10 forms.First suction passage 22 has preceding working edge 40 and back working edge 42.Second suction passage 24 also has preceding working edge 44 and back working edge 46.Working edge is limited shrilly, so that provide effective brush moving action when ground instrument 10 is used on the carpet surface.On this surface, wheel 21 is absorbed in the tuft of carpet, so that working edge contacts with carpet.

Ground instrument 10 also comprises at least one air duct.In this example, this at least one air duct is the form of two conduits 48, and each conduit defines by the back working edge 42 of first suction passage 22, the inwall of center-aisle 36 and the preceding working edge 44 of back suction passage 24.Each conduit 48 extends downwardly into the basal surface 18 of ground instrument 10 from the upper surface 52 of ground instrument 10.Each conduit 48 opens into atmosphere.

Fig. 5 a and 5b schematically shown in use air channel 48 and the function of working edge.In Fig. 5 a, ground instrument 10 is pushed away forward along the floor surface of carpeting, and this direction is represented by the big arrow above upper surface 52.Ground instrument 10 is communicated with the vacuum cleaner fluid that produces the suction air-flow, as will discussing later.Ground instrument 10 in front travel, the preceding

working edge

40,44 of each

suction passage

22,24 enters duty.Before working

edge

40,44 launch the tuft of carpets can flow and enter

suction passage

22,24 around preceding

working edge

40,44 so that suck air, as than shown in the small arrow.Air is drawn through and into first suction passage 22 of suction chamber 20 for 40 times at the antetheca 30 times of main body 12, at preceding working edge.Air from first suction passage 22 flows through center-aisle 36 and enters second suction passage 24, and leaves suction chamber 20 by exporting 34.Air is also sucked by air channel 48 from atmosphere, enters second suction passage 24 of suction chamber 20 through preceding working edge 44 belows.Air from second suction passage 24 leaves suction chamber 20 by exporting 34.Outlet 34 has bell mouth, so that at second suction passage 24 with export the transition that provides level and smooth between 34.

In Fig. 5 b, ground instrument 10 is pulled to returning along the floor surface of carpeting, and this direction is represented by the big arrow above upper surface 52.In the stroke backward of ground instrument 10, the

back working edge

suction passage

22,24 enters duty.Air by air channel 48 from atmosphere and through after working edge 42 belows suck and enter into first suction passage 22.Flow through center-aisle 36 from the air of first suction passage 22 and enter second suction passage 24, leave suction chamber 20 by exporting 34 then.Air also below the rear wall 32 of main body 12, back working edge 46 below suck and enter into second suction passage 24.Air from second suction passage 24 leaves suction chamber 20 by exporting 34.

Thus, for each stroke of ground instrument 10, a plurality of working edges work, so that the picking up to compare with the conventional ground instrument that only has a suction passage and two working edges and be improved of foul and dust.Connect by the fluid that extends along the

sidewall

26,28 of ground instrument 10 is set between first and

second suction passages

22,24, the ground instrument with a plurality of suction passages and working edge can be manufactured to the single suction that has with conventional and go into the similar size of passage ground instrument.Specifically, the degree of depth of ground instrument 10 can be manufactured to less relatively, so that ground instrument 10 has lower attitude.This advantage can be seen in Fig. 3 and 4 better.

The details of suction chamber 20 can see in Fig. 2 and 6 that they show the lower portion of ground instrument 10 in greater detail.Suction chamber 20 does not have the cross section of homogeneous.First suction passage 22 has middle section 54, and this zone has the cross-sectional area of minimum suction chamber 20.The part of 56 (showing in Fig. 6) of cross-sectional area longshore current body flow path increases, and the remainder along first suction passage 22 extends to the outward flange that it closes on ground instrument 10 sidewalls 26,28 to this part from middle section 54.The cross-sectional area longshore current body flow path 56 of suction chamber 20 to extend to that part of of second suction passage 24 from first suction passage 22 along center-aisle 36 be basically identical.The cross-sectional area of suction chamber 20 is that part of increase that extends to outlet 34 from middle passage 36 along second suction passage 24 of longshore current body flow path 56 also, and this outlet is arranged in the middle body of the rear wall 32 of main body 12.In order to adapt to this shape of suction chamber 20, air channel 48 is arranged to altogether forming V-shape and summit near the middle section 54 of first suction passage 22.Have the cross section of increase by at least a portion that suction chamber 20 is arranged as longshore current body flow path 56, in whole suction chamber 20, can keep substantially invariable fluid pressure.This provides the further advantage on performance, because it can guarantee that air is drawn in two suction passages 22,24 equably on the whole width of striding suction passage 22,24.

The width that preceding working edge 40 and back working edge 46 stride across the main body 12 of ground instrument 10 extends.In order further to increase the effect of the working

edge

42,44 that closes on air channel 48, these edges extend to sidewall 26,28 by bridgeware 58, and described bridgeware 48 is across center-aisle 36.Bridgeware 58 extends to sidewall 26,28 and less path also is provided from the opposite edges of air channel 48, is used for fluid and flows below those parts of the working

edge

42,44 that is formed by bridgeware 58 and along these parts from sidewall.Bridgeware 58 can form the integral part of the basal surface 18 of ground instrument 10.The working edge of the whole width by basic extension ground instrument 10 is set can realize that bigger brush action uses.

Lint picker 60 is arranged on the office, front and rear part that is positioned at ground instrument 10 on the basal surface 18 of ground instrument 10, and spaced apart with working edge 40,46.Each lint picker 60 comprises the material band that is fixed with a plurality of fiber fines clumps.The reciprocal front and back action of ground instrument 10 on floor surface can be caught hair, fine hair and other fibrous materials and it is rolled into ball, so that it can be inhaled in the suction chamber 20.Using lint picker 60 can cause the user to promote on floor surface or spurring ground instrument 10 needed power increases.The width that can increase lint picker 60 is to reach the overall width of ground instrument basically, and required thrust increases although this can cause the user.

Air delivery valve 62 is arranged in the upper surface 52 of ground instrument 10.For example be inhaled under the situation of the fabric obstruction in the

suction passage

22,24 at suction chamber 20, the pressure in the suction chamber 20 can descend.When the pressure in the suction chamber 20 drops to when being lower than predetermined value, atmospheric pressure acts on the air delivery valve 62 and the power of antagonistic spring 64 inwardly promotes air delivery valve, is provided for allowing atmosphere enter the opening of ground instrument 10 thus.When obstruction was removed, making every effort to promote of spring 22 made air delivery valve 62 get back to its home position, flushes with upper surface 52.

In order to obtain the best possibility performance from ground instrument 10, importantly working edge keeps contacting with ground when ground instrument 10 is spurred with promotion along floor surface.In order to realize this point, outlet 34 and with connector 16 that the push rod and the flexible pipe of vacuum cleaner are connected between joint piece is set.Joint piece is with the form setting of flexible inner hose 66.An end 68 of inner hose 66 has wide mouthful, and the flute profile that this wide mouth is assemblied in suction chamber 20 exports on 34 and against exit seal.The other end 70 of inner hose 66 has circular cross-section and is arranged as and is assemblied on the neck 72 and against neck seal, and this neck is assemblied in again in the connector 16.Neck 72 is connected to and preferably is incorporated into second pair of arm 74, and this second pair of arm 74 extends towards the main body 12 of ground instrument 10.Each arm 74 can be pivotally connected to first corresponding one end of the 3rd pair of arm 76 near the one end.This provides first articulated joint 78 of ground instrument 10.Second end of each arm 76 is pivotably connected to the respective arms 15 of the main body 12 of ground instrument 10.This provides second articulated joint 80 of ground instrument 10.First and second joints 78,80 pivot around the axis that is parallel to floor surface.Inner hose 66 provides the positiver sealing of air path between outlet 34 and connector 16, and allows motion and flexibility simultaneously.

Connector 16 is arranged as with respect to neck 72 and winds axis rotation perpendicular to the axis of first and second joints 78,80.Neck 74 and connector 16 rotatably be connected to form the 3rd joint 82, this joint allows instrument laterally to move.In use, three joints allow ground instruments 10 to be handled and turn to, and keep contacting of working edge and carpet simultaneously, so that the increase of the pickup capacity of instrument.The dual articulated structure of first and

second joints

78,80 allows to be applied to wheel 14 transmission of the power of ground instrument 10 by ground instrument 10 by the user.This helps to reduce the resistance of motion, also allows the user to finish longer stroke and keeps ground instrument 10 to lie prone on floor surface simultaneously.

Fig. 7 a and 7b have shown the alternative that is articulated and connected of the parts shown in Fig. 5 a and the 5b.In this alternative, first and

second suction passages

22,24 are relative to each other hinged.Flexible joint 84 is connected to second suction passage 24 with first suction passage 22.In Fig. 7 a, ground instrument 10 is promoted forward along the floor surface of carpeting, and this direction is represented by the big arrow above upper surface 52.Ground instrument 10 in front travel, flexible joint 84 allows first and

second suction passages

22,24 to pivot forward,
