Description

Suction floor cleaner, especially adaptor and details of electric suction cleaner

The present invention relates to a kind of floor suction device, especially a kind of annex of electric dust collector or parts, can be used for clearing up carpet surface or hardstand, has the brush spare and a suction chamber that can drive rotation, it is limited by curtain structure, simultaneously, curtain structure can draw up or put down with respect to the floor suction device.

This floor suction device is known, and this device for example is placed on the electric dust collector by a pipe connection.This floor suction utensil has discerptible, as to be used for rotating a brush roll that is provided with at a housing electric driver.The cleaning on general fabrics surface realizes by suction dust dirt dirt, and the dust and dirt dirt is by inserting in the mouth spare, and touches that the brush roll of carpet draws.When the cleaning hardstand, the danger of existence is that the suction nozzle spare arris that contacts with hardstand can be damaged by hard place.For avoiding this point, suction nozzle spare is mentioned, a segment distance overhead, this point for example realizes by the rigidity wool top, and wool top is around the suction nozzle setting.Mention whole suction nozzle by this, the air suction inlet of suction nozzle spare is enlarged.Because this opening is determined size from certain, just no longer effective swabbing action may have been had, so the sealing device of described opening by curtain structure must be dwindled.To this, knownly be, one with by the vertically moving plate in clean and tidy ground on curtain structure all is set, this plate is ringwise around the suction nozzle setting.This support plate can and stretch out by mechanism's retraction.Therefore, can realize this suction nozzle is raise a bit from treating clean and tidy ground.To this, significant disadvantages is that this device must have a quite high stagnation chamber in suction nozzle spare, thereby the structure height of suction nozzle spare has been strengthened.Like this, hindered the performance on cleaning furniture or the following ground of analog.

Task of the present invention is, the floor suction device of the above-mentioned type is improved, and manufactures with plain mode as far as possible, simultaneously on carpet surface, or all can provide desirable suction effect on hardstand.

Task of the present invention is to solve by the invention technical scheme that independent claims are put down in writing.

Dependent claims has been described the favourable modification of technical solution of the present invention.

Structure setting of the present invention provides a kind of floor suction device, and it and all has desirable pumping efficiency not only on carpet surface on hardstand.Consider that for this reason curtain structure can be implemented a motion that overhead highly has nothing to do with the floor suction device.Thus, adopted the flexible program of suction muffler, or rather, realized the adjustability in the suction gap that the relative ground of suction muffler exists by a movable curtain structure, this curtain structure need not change the floor suction device height and position that reaches brush roll whole or the brush part and just can rise or descend.Opposite with prior art, herein for curtain structure is moved, and floor suction device or absorbent brush device are mentioned.Distance between chassis backplane and ground for clearance not only all can be in same position when cleaning carpet but also when the cleaning hardstand.This distance is to determine with known manner, and promptly moving wheel or the analog that is provided with by dust catcher decided.In order to clear up carpet surface, this curtain structure remains on the position of a rising., relate to swabbing action herein, then itself and carpet are separated by brush spare that settle and that touch carpet in casing suction nozzle spare to dust and dirt to dust and dirt.The air suction inlet of suction nozzle spare is that the edge bearing by suction nozzle spare is placed on the carpet surface and limits.When suction ground, saved this supporting, therefore have apart from ground under the situation of height at dust catcher, just cause the expansion of suction nozzle spare air intake.Therefore, this inlet determines that from certain size just no longer has effective swabbing action, and the air velocity that therefore causes aspirating by excessive air-gap is too little for drawing dust and dirt.So above-mentioned inlet must be dwindled by curtain structure.At this moment, curtain structure is so to descend, and promptly it rests on the hardstand for clearance, and realizes the qualification of a suction muffler according to this.The mobility of curtain structure or reactive for example can take to make curtain structure to forward the position of a rising to or also can on the contrary from the position of a decline.Promptly this curtain structure can for example be turning motion be placed on the bottom of floor suction device.Above-mentioned curtain structure is used for as already mentioned when the cleaning hardstand with seal form or a kind of row's of brush form as the sealing device that limits suction muffler.Stipulate that in a preferred structure scheme decline of curtain structure is to realize by a configuration that takes place in basic horizontal moves.In addition, curtain structure leading like this in a background part promptly by the turn translational motion of arris of a curtain structure, is realized the decline of curtain structure and is compiled and change.This structure setting requires curtain structure to have rigidity.Other optimal way is that the decline of curtain structure or rising are by switching manipulation, as the foot-switch operated by dust catcher.The decline of curtain structure can so be carried out, and promptly utilizes the pretension of a spring to act on the position of decline.At this, can expect that this curtain structure can remain on the position of rising by Bowden cable or analog.After this, after a switch or analog operation, Bowden cable is lax, and this curtain structure moves to the position of decline by spring tension thus.Especially, be that this arris of turning is a turning cylinder simultaneously under the situation of slide plate guiding at curtain structure.If when for example being set to curtain structure with a sealing lip, this sealing lip can also be in a guiding structural, and is particularly ccontaining in the guiding structural with respect to the longitudinal extension of sealing lip of edge side.Therefore, sealing lip can also always be intercepted and captured by this guide mechanism with its tip at the state that rises.When the preceding motion of a basic horizontal is done in turn arris or rotating shaft, the tip of this curtain structure or sealing lip just automatically move by guiding structural and deflect into hope on upper/lower positions.Thus, this rotating shaft can remain on the slide plate of a basic translational motion, and therewith moves.For example, aforesaid embodiment can so constitute, promptly in order to seal suction muffler in preceding edge regions, also use the rigidity wool top of curtain structure to descend where necessary in the side area, simultaneously, (for a moving direction of dust catcher) is provided with very thin, a flexible sealing lip in the edge regions of back, and it carries out the motion of a translation and rotation simultaneously, according to this, it has a position perpendicular to the ground when suction ground.Because this function, the sealing property of suction muffler is no longer necessary, has reached in other words.So, the sealing lip just is positioned on parallel with the treating suction surface basically position, is not subjected to any mechanical stress and prevents to be subjected to unnecessary pollution.Simultaneously, the fault that causes of this position Wear and reduced maloperation danger effectively.When the cleaning hardstand, it is that the sealing lip is positioned at the position perpendicular with hardstand by a sealing lip sealing thin and flexibility that the border of suction muffler back requires according to the present invention.Have at sealing lip under the situation of enough high flexibilities, can also avoid hardstand to be cleaned because the damage that the dust and dirt particle causes.Simultaneously, such sealing lip also has high self-cleaning property.The translation of combination seal lip and rotation can also avoid sealing because of building up dust and dirt, the jammed danger of rubbish.The organization plan of the invention described above, owing to use the member of reduced size, can allow only has several millimeters very little structure height.In addition, directly be combined in the seat portion of dust catcher with it, can realize a very little structure height thus owing to use the slide plate of little wall thickness.In addition, in the hard floor surface cleaner operation, the dwindling of air suction inlet, promptly the relative ground clearance of suction muffler reduce to be so to realize, promptly the bottom side of this suction nozzle spare is provided with the hermetically-sealed construction of one two bulk-breaking formula.Side for example can be provided with (non-adjustable height in principle) rigidity wool top as hermetically-sealed construction in front, and back side edge be provided with one adjustable for height, and for the sealing lip form, also can be another rigidity hair row's hermetically-sealed construction where necessary.This two bulk-breakings formula hermetically-sealed construction can also be by one on the width of suction nozzle spare and on one or two side, the perhaps sealing mechanism that on a width of suction nozzle spare, extends, or formed by a sealing mechanism or a curtain structure that extends in the motor side or the brush part side of suction nozzle spare.In addition, for example can have self a motor based on, this dust catcher, it is placed in the back of suction nozzle spare along the traffic direction of dust catcher.This curtain structure, it can be made into the sealing lip of adjustment height or brush row's hermetically-sealed construction, also can be made into a direction on the width that extend and of the part zone of suction nozzle spare bottom side, particularly towards the sagging folding sealing film of the direction of hardstand towards ground at suction nozzle spare.To this, its implementation promptly, curtain structure, the especially decline of the adjustable for height sealing device of a sealing lip structure or rising are by the folding of a thin-film member or launch to realize.In addition, the thin-film member of this expansion rests on the downside of dust catcher bottom basically.Thus, the curtain structure of the thin-film member form of this set just can be realized a very little structure height.The curtain structure of this form of film can rise or descend with this frame mode, promptly folding with launch be relative thin-film member folded end district basic horizontal be moved into horizontal generation.In thin-film member is under the situation of sealing film, folding (bag) is implemented into extends hardstand to be aspirated.The foldable bag of Gou Chenging outside top line can rest on the ground like this, and perhaps the landing ground operation is wiped by the side when mobile dust catcher on the ground.When utilizing the dust catcher cleaning carpet, the corresponding cooperation be, sealing film can be folded into bag, the expansion form settle or extend on the bottom of suction nozzle spare.Sealing film can be by a kind of flexible, and plastic material especially is made of plastics or metallic film.In addition, in service to clean fabric, the return that does not need desirable folding (bag) performance that is used to seal and arrive suction nozzle spare bottom side.Specifically, the sealing film can be made into the structure of multilayer, is promptly made by the material of one or more layers elasticity restorable, especially moors by plastics with by the metal of one or more layers elasticity restorable to constitute.In addition, in other concrete structure, the sealing film can be provided with the rigidity hairpencil at lateral surface.That is has the bristle row of a combination and as the sealing or the sealing film of curtain structure.On the width of suction nozzle spare, the sealing film can also have one or more wrecking.Especially can also be that having only independent sealing film segmentation is mobilizable with the form of folding (bag).In addition, the sealing film can also have two folding (bag) structures, especially sees on the longitudinal cross-section, so constitutes two front and back folding (bag)-apex lines successively on traffic direction.The sealing film can also have two or more strengths of materials.Folding (bag) of sealing film and return (expansion) can realize sealing film thickening or stretching slide plate by one, and this slide plate can be a mechanically movable.In addition, this slide plate also can move by the energy (for example motor) that settle in the suction nozzle spare or top.In a word, the decline of sealing lip can realize by a configuration that takes place in moving horizontally.Like this, the longitudinal edge side moves by a longitudinal edge, and essentially horizontally shifts near mutually, and the decline of sealing lip is to finish by constituting stretch out folding downwards.In addition, can also make up on aforesaid dust catcher embodiment a known total adjustable height performance mechanism is set, it is not to be exclusively used in the rising of curtain structure and decline.The latter is that the rising or the decline of curtain structure is irrespectively to realize and can rise or descend with possible adjustable height performance.This just means, in this combination embodiment, curtain structure is not only in the low position of an adjustable for height dust catcher, and all can rise or descend in the high position.In addition, can also make rotating brush spare be arranged to an adjustable height structure (mode to add and to make up in addition in case of necessity), the independence of a motion of curtain structure is guaranteed in the setting of this structure simultaneously.

The invention still further relates to a suction nozzle spare that is used for cleaning device, suction nozzle spare in particular for the floor suction device, it have one that the time contact in the operation of cleaning carpet with ground to be aspirated and when hard floor surface cleaner move from aspirating the ground lifting that makes progress, and be provided with the brush roll of a rotating motorized motions or the suction nozzle spare of analog.Advise during hardstand in cleaning, the qualification of suction muffler can be partly by static curtain structure with partly realize by mobilizable curtain structure.To this, for example can also do following selection to structure setting, that is, static curtain structure is to be placed in regularly on the bottom of floor suction device, preferably is placed in the front and the side of (dust catcher traffic direction relatively) suction muffler.This mobilizable curtain structure preferably can be placed in the dorsal part of suction muffler with rising or descend.Simultaneously, the rising of movable curtain structure or decline can be irrespectively to be provided with the corresponding height and position of nozzle body.For this reason, aforesaid all embodiments can be used the curtain structure that can rise or descend.Alleged curtain structure can also be arranged to the structure of sealing lip.It will also be appreciated that, a rigidity wool top is set as curtain structure.Realizing that preferably this static curtain structure is that the rigidity hair is arranged under its suction muffler suction nozzle spare situation that to be part is limited by movable curtain structure by static and part, this movable curtain structure is the structure of sealing lip.But can expect that also be not only staticly, and movable curtain structure all is the structure of rigidity wool top.In addition, this static and curtain structure activity are the structure of sealing lip all, are in particular the form of sealing film, and it is provided with the rigidity hairpencil.

The present invention relates to an absorbent brush device that is used to clear up carpet or hardstand in addition, it has, the brush spare that rotates drivable by motor and has cleaning rigidity hair spare in front.Stipulate in the preferred construction scheme herein that cleaning rigidity hair spare can be vertically descends owing to switching manipulation at one and moves by putting between ground position and a lifting position.And the motor-driven of brush part can be switched on or switched off simultaneously, and wherein, cleaning rigidity hair spare is exactly a curtain structure according to previously described implication.Motor-driven being switched on or switched off of roll brush can be realized in the process of the switching manipulation of cleaning rigidity hair spare.Rise this moment, just can that is to say according to the ground object, according to whether aspirating carpet or hardstand, makes cleaning rigidity hair spare descend or rise, and, can also finish the motor-driven on or off operation of brush part simultaneously herein.Like this, for example when the suction carpet surface, wish the motor-driven connection, simultaneously, this cleaning rigidity hair spare is retained on the position of rising.When suction carpet suede yarn or analog, according to the purpose requirement, motor-driven is disconnected, simultaneously, cleaning rigidity hair spare herein rises.In contrast, best suction mode is when hardstand, and cleaning rigidity hair spare rests on the ground, and herein, this motor-driven disconnects.But it will also be appreciated that,, also this drive unit can be connected for a better cleaning.In order to realize operating the diverse location or the motor-driven position of the switch of these cleaning rigidity hair spares, this suction nozzle brush device has a switch, and it not only is used to clean the decline and the last lift operations of rigidity hair spare, and is used for the operation that switches on and off of above-mentioned driving.Stipulate that in a preferred construction scheme under the rigidity hair spare situation that descends, brush drives and disconnects.This just means that in the process that the rigidity hair spare of settling descends, simultaneously, the motor-driven of brush roll is disconnected before rotating brush roll.Stipulate in addition in an advantageous manner that also under the rigidity hair spare situation that rises, this brush roll drives and can connect maybe and can disconnect.When suction carpet surface or similar, should be that rigidity hair spare is lifted, simultaneously, rotate the motor-driven of brush roll and connect.This position of switch can be decided to be home position.Leave this home position, can pass through switch, motor driver is disconnected, in the time of for example should aspirating carpet knitting wool or analog.At this moment, then can on the rotation brush roll, twine knitting wool, may cause the fault of damaging carpet or causing the absorbent brush device like this if connect motor-driven.Apparatus of the present invention are to make operating technology Utopian especially like this, i.e. switching manipulation can realize by a floor push.According to the purpose requirement, this floor push is placed in and is easy to approaching zone in the absorbent brush device.It will also be appreciated that, the floor push of two arranged parallel is configured in the both sides of the pipe joint of electric dust collector this moment.Be used to make cleaning rigidity hair spare to descend or rise and make under the floor push situation of the mechanism that drive unit is switched on or switched off having one, these floor push are connected each other antitorquely.Preferably such mechanism can so be provided with, and promptly floor push is connected with rigidity hair spare or a rigidity wool top by a Bowden cable.One is preferably in the rigidity wool top of using in the absorbent brush device, can be placed on a position decline or a rising by Bowden cable and by deflecting roller with according to the mode of operation of floor push.This structure setting can so be made optimization and select, and promptly rigidity hair spare or rigidity wool top are loaded on the position of its decline by a compression spring.At this moment, only Bowden cable is freely relaxed, so that realize a down maneuver of rigidity hair spare or rigidity wool top by compression spring by floor push.For making the optimization that moves both vertically of rigidity hair spare or rigidity wool top, two Bowden cables are set preferably herein.It will also be appreciated that thus, two rigidity wool tops of absorbent brush device equipment of this version, one of them is placed in the front of rotating brush roll, and another is in its back.According to this, the low-pressure cavity that constitutes when suction hardstand or analog can cause a desirable swabbing action to ground.Mention that as the front in such position, that is under the rigidity hair spare situation that descends, brush roll drives and disconnects.In an advantageous variant of technical solution of the present invention, stipulate, this rigidity hair spare or rigidity wool top are the fronts that is placed in brush roll, and sealing lip is the back that is placed in brush roll, and the sealing lip can move both vertically with rigidity hair spare (in the same manner) equally.On the meaning that this sealing lip illustrates in front be exactly a curtain structure herein.Thus, just can constitute a desirable low-pressure cavity according to aforesaid design, this is very favorable when suction face brick flooring or analog especially.The dirt particle that these embed in the face brick seam under rigidity wool top that descends and sealing lip situation, as long as formed low-pressure cavity, just can be sucked away best.Sealing lip and rigidity wool top are to be lowered by in switching manipulation or to rise.Can expect thus that also sealing lip and rigidity wool top are loaded on the position of its decline by a compression spring accordingly.In another organization plan, can stipulate that two switches are settled up and down, simultaneously, following switch is operated by the switch of top.For this reason, structure setting can so be selected, and promptly the switch of this top is realized the disconnection or the making operation of a brushroll motor, and following switch is finished the rising or the step-down operation of a curtain structure.Herein, this curtain structure can be the structure of brush bar or sealing lip, in a preferred structure scheme, stipulate, a slight operation to the top switch, can realize the action that is switched on or switched off of brushroll motor, and the operation of a brute force, then cause the switching motion of following switch, therefore, correspondingly curtain structure is risen or is descended.As already mentioned preferably, when the cleaning hardstand, the motor-driven of brush roll disconnects.Also have this point under alleged organization plan situation, can consider at brute force operation top switch with therefore and then when operating following switch, on the one hand curtain structure descend and on the other hand the motor of brush roll disconnected, otherwise perhaps.Herein, this organization plan is optimization so, and promptly Xia Bian switch is covered by the switch of top.For the switch of guaranteeing the top always is moved back into after an operation on its home position, special regulation, the switch of this top is that elastic bearing is on following switch.But also can expect, the switch of this top be elastic bearing in the casing side, that is elastic bearing is on the casing of absorbent brush device.Similarly, this following switch also can flexibly be bearing on the dust suction casing.One foregoing so in a base member under the curtain structure situation of leading, that is when the arris of turning of this curtain structure was basic translational motion, a decline will take place curtain and deflection is moved.To this, the present invention stipulates that in a preferred structure mode this following switch essentially horizontally moves the arris of turning (bus) of curtain structure by a rod member.Rotating arris or constituting rotating shaft thus when being the forward movement of level, this curtain structure that is preferably sealing lip just moves and deflects on the desirable down position.For this reason, curtain structure is inserted in the bare bones as previously mentioned, and wherein this arris of turning can move, and this bare bones is constituted by a floor piece with by the cover piece of a case side simultaneously.In addition, this floor piece is dismountable structure, and therefore after floor piece was pulled down, curtain structure can freely be placed wherein.Thereby curtain structure (sealing lip) just can be changed.In order to come the motor of break-make brush roll as requested, stipulate that also not only the switch of top but also following switch act on respectively on the contact-making switch, two contact-making switches all can be switched on or switched off the brush roll driving simultaneously.A preferred disposition is for this reason, and the on-off action of top is on a contact-making switch, and its each operation is all sent a pulse and is used to be switched on or switched off the brush roll driving.Preferably use an opening type switch as the contact-making switch of following switch, its general brush that disconnects when the following switch of operation drives, and the pulse signal of sending at last with the top contact-making switch is irrelevant.This means that when the curtain structure that descends was used to clear up hardstand, brush roll was general inactive state.The then deflection of implementation structure to a down position of operation of following switch.For the information about absorbent brush device moment running status is provided to the operator, advise being provided with the function signal lamp and be respectively applied for brush operation and suction operation, only be used to aspirate the suction operation that moves and be used to have the curtain structure of decline.This means that when normal operation, that is when the suction carpet surface, a function lamp is bright, therefore informs the user, not only the motor of brush roll is connected, and curtain structure is to be in the position of lifting.By the slight mode of operation to the top switch that is preferably the floor push structure, then brush roll is disconnected after leaving this normal position.This mode of operation is to show by an other function lamp.To top switch (floor push) with under the operational circumstances energetically, by the effect on following switch, then realize the down maneuver of a curtain structure, and be not formerly to take place, the then motor-driven of brush roll disconnection as this action.And this 3rd running status is by an own function lamp demonstration.In an advantageous manner, these function lamps also can further be utilized, and promptly under the brush roll operation was stuck situation, the flash of light operation of all functions lamp had just been connected.If under suction carpet suede yarn situation, the brush driving does not formerly have to disconnect by the switch (floor push) of top as an example, this just may cause the braking (blocking) that a brush drives so.For avoiding damaging carpet fabric and absorbent brush device, this device has a motor-driven function of automatic disconnection when brush roll blocks.This state is to indicate by the flash of light of all functions lamp now, so the user is apprised of, and brush roll and carpet suede that plays braking action or analog must be broken away from.

In the embodiment of another floor push, in order to realize the different position of the switch, also be defined in brushroll motor and drive when being switched on or switched off, brush bar and/or sealing lip descend or rise.For this reason, this floor push has a locating journal, and it and base member mating reaction in base member, are provided with and the corresponding location contained structure in the position of the switch accordingly.Like this, can in several switch classifications, connect from a foot control home position.Simultaneously, not only once cross the connection of several classifications, and all be possible from each classification tieback to basic classification.For this reason, preferably a base member has the location contained structure that is used for three position of the switch.First position of the switch relates to home position, and wherein, the brush roll of rotation is preferably used motor-driven, and rigidity wool top and/or sealing lip still are retained on the position of rising by Bowden cable.In the second switch position and under preferred motor-driven scheme situation, brush (roller) part disconnects, and simultaneously, rigidity wool top and/or sealing lip continue to be retained in lifting position.Come out from this position of the switch, directly tieback is to home position, that is first position of the switch.Not only come out, and come out, can be switched to the 3rd position of the switch by the second switch position from home position.At this moment, this motor-driven is disconnected with Bowden cable is lax simultaneously.Therefore, as long as have under the compression spring condition, this brush bar and/or sealing lip just descend and move.Yet come out directly tieback to home position from this 3rd classification.Preferably adopt one wherein base member is for turning the organization plan of location and installation for this reason, and the while is controlled by locating journal when rotational motion.With the configuration of Bowden cable on floor push, be so to realize by advantageous manner, promptly the control axle journal of Bowden cable is a leading in the slotted hole of a fixed head, and can operate by a floor push plate.According to the position of the switch, can remain on pulling force position or free off-position by the floor push plate at the control axle journal of the slotted hole leading that is arranged in the shell-side fixed head.For this reason, this floor push plate can be provided with projection or similar structures, and this structure will be controlled axle journal for the lifting position that realizes rigidity wool top and/or sealing lip and remain on the home position, this moment this Bowden cable with the rightabout of the spring force of rigidity wool top and/or sealing lip compression spring on be tightened up.Under operation floor push situation, the bulge-structure of floor push plate just discharges the control axle journal, so this axle journal can freely-movable in slotted hole.Because the spring force of compression spring, the rigidity wool top of this moment and/or sealing lip just descend.Therefore, in a favourable organization plan, stipulates, the curved profile structure is set, can move, and the control curve is that structure so is set that promptly the control axle journal is removable when arriving the 3rd position of the switch by its this control axle journal in the floor push plate.Describe as the front, in first position of the switch and second switch position, this brush bar and/or sealing lip are upborne.In addition, disposed slotted hole in fixed head, control shaped form profile is set in floor push, the selected of it is when first and second position of the switch, and the control axle journal is not freely discharged or is moved.At this moment, motor-driven being switched on or switched off of this rotation brush roll can realize that this electronic switch is positioned at home position by an electronic switch, promptly will brush part drive current circuit closed in first position of the switch and connect.This point for example can realize like this, promptly settles a cam on floor push, and it affacts on the electronic switch.When arriving the second switch position, this cam leaves the electronic switch zone, so this switch disconnection, and the circuit loop that the brush part is driven interrupts.As top described, the control axle journal of Bowden cable also can not move herein, so rigidity wool top and/or sealing lip still are retained in the position of rising.

In suction muffler 15 and before brush roll 11, settle the rigidity wool top 19 of a V-arrangement curtain structure.It becomes respective transversal ground to extend in the mode as brush roll 11 with the moving direction of absorbent brush device 10.In the suction nozzle district and in that side that brush roll 11 deviates from rigidity wool top 19, settle a sealing lip 20 that is similarly the V-arrangement curtain structure in the same manner.The length of brush roll 11, rigidity wool top 19 and sealing lip 20 and the same length of suction muffler 15.

Not only the rigidity wool top 19, and sealing lip 20 all is vertically maneuverable, they respectively by one at the

compression spring

21,22 of housing upper support and pre-loaded on the position of a decline.

For rigidity wool top 19 and sealing lip 20 are moved on the raised position, they are connected with floor push 17 by two Bowden cables (pull bar).

Floor push 17 comprises mainly that the relative operation panel 24 of an operation panel 24 that extends laterally from housing 3 and a side is rectangular and settles thereon floor push plates 25.Its configuration is, floor push 25 be material integrally formed at operation panel 24 on a side of housing 13.Two floor push 17 have identical member and also are symmetric arrangement.As already mentioned, floor push 17 connects by a clutch lever 18 relatively antitorquely, and wherein, the end of clutch lever 18 is to be fixed in the zone of floor push plate 25.On rigging position, floor push 25 rests on the fixed head of fixing with housing 26 reposefully with its side facing to housing 13, and clutch lever 18 is distolateral respectively by plates 26.

Each floor push plate 25 has the control contour curve 27 of a given shape, wherein inserts one and passes L shaped slotted hole in the fixed head 26 and at the (see figure 4) control axle journal 29 of slotted hole regional movement.These penetrate control axle journal 29 and lever 30 in the corresponding floor push 17 with control lever 31 and be connected mutually antitorquely.

Be fixed with Bowden cable 23 at free end by the elongated hole 28 and the control axle journal 29 of control curve 27.

Each fixed head 26 also has one and is arranged in the groove 32 that deviates from slotted hole 28 zones, and it is used to hold a slide plate 33.This slide plate 33 is to be placed in pivotally on the side of floor push 25 by the axle journal 34 of a fixed head side.

This slide plate 33 is being mounted with a pattern shape guider 35 on the side of floor push plate 25, it constitutes by keeping pattern shape projection 37 and milling out pattern track 36.

At above-mentioned guider 35, that is to say and in pattern track 36, set a locating journal 38 that is positioned at the floor push side.

Operation panel 24 and its floor push plate 25 of going up shaping are stretched on Fig. 4 and the home position shown in Figure 5 by a helical spring 39 and constantly in advance.Simultaneously, this helical spring 39 encloses to be put on clutch lever 18, and an end is fixed on the clutch lever 18, and the other end is fixed on the fixed head 26 of case side.In addition, clutch lever 18 is equipped with a switch cam 40, key switch 41 mating reactions of it and housing.

The working method of above-mentioned floor push 17 is as follows:

In first position of the switch (it is corresponding with home position) according to Fig. 5.The operation panel 24 of floor push 17 is positioned at an almost position of level.At this moment, locating journal 38 holdings of floor push plate 25 are in the first location accommodating structure A of guider 35.40 pairs of key switches 41 of the switch cam of clutch lever 18 apply effect, so this switch 41 is connected the current loop of roll driving apparatus 12.So brush roll 11 is by motor-driven.Control axle journal 29 is to remain on the home position by the control curve 27 of floor push plate 25 in slotted hole, this position is, Bowden cable is not only with rigidity wool top 19, and sealing lip 20 is remained on the raised position shown in Figure 6 by conversioning wheel 42.

The made locating journal 38 that floor push 17 is done sails among one the second location contained structure B by pattern stroke X.In this motion, the clutch lever of settling in fixed head 26 18 so rotates, and promptly switch cam 40 is left the zone of press button 41, thus the electric current input of roll driving apparatus 12 is interrupted, and then the motor-driven of roller 11 is just interrupted.By control curve 27 classes subreniform structure setting, this control axle journal 29 is maintained on its home position, so rigidity wool top 19 and sealing lip 20 just are retained in (see figure 7) on the position of this lifting.

From location contained structure B, by pattern shape journey Z, just can occupy one the 3rd position of the switch, at this moment, this locating journal 38 moves among the location contained structure C and at this by pattern stroke Z and fixes.The floor push plate that causes thus 25 being rotated further of clutch lever 18 supporting-points in the fixed head 26 causes that then the kidney shape control curve of settling 27 makes control axle journal 29 that the there runs through spur together along the slotted hole of fixed head 26 on this floor push 25.Because the supporting role of the spring force of

compression spring

21 and 22, rigidity wool top 19 herein and sealing lip 20 just drop to one and rest on ground position.The switch cam 41 of clutch lever 18 is still stayed beyond the scope of key switch 41.Therefore, be still interruption to the electric current of roll driving apparatus 12 conveying this moment.The rigidity wool top 19 described in Fig. 9 and the down position of sealing lip 20 show that under the 3rd position of the switch situation of floor push 17, the suction muffler 15 in brush roll 11 scopes spatially separates with the external world.Therefore, and ground between the zone form a low-pressure area, it will have the desirable suction floor tile or the effect of analog.By floor push 17, can also promptly from home position, cross the second switch position from first position of the switch, insert the 3rd position of the switch in the rectilinear path mode, this realizes by pattern shape journey Y.In addition, can insert first position of the switch (home position) not only from second switch position process pattern stroke X ', and from the 3rd position of the switch through pattern stroke Y '.

From the 3rd position of the switch tieback during to home position, with lifting of rigidity wool top 19 and sealing lip 20 is to support by the returning place force of helical spring 39, so this floor push plate 25 that is turned back to home position will be controlled axle journal 29 along slotted hole 28 interlocks by control curve 27.Thus, essential is that the spring force of helical spring 39 is greater than the compression spring 21 of rigidity wool top 19 and sealing

lip

20 and 22 spring force.

In Figure 10 and 11, show the dust collector device 10 in second embodiment, it is the version of the dust catcher 43 of a translator 12.By a transmission device 44, make brush roll 11 carry out rotating drive.Represent in a schematic way in the drawings a brush row who on brush roll, settles 11 '.On brush roll 11 circumference, be provided with a plurality of such brushes row 11 '.This floor suction device 43 also has a mouth spare, its for band inhale the suction nozzle 10 in chamber 15 ' version.This suction chamber 15 is front rigidity wool top 19 sealings by a leading edge 45 and a V-arrangement curtain structure.

Figure 10 describe under the state that moves on the carpet surface, suction muffler 15 is by edge rib 46 sealings of a back.Owing to be bearing on the yarn matte of carpet surface, therefore suction muffler 15 formed one and still can allow air pass through, but be the qualification effect of sealing on the quite big degree.Therefore, by the high gas flow speed that reaches, just can realize dirt or dust and dirt component or analog are aspirated the effect of walking from carpet surface.

In addition, the dorsal part of brush roll 11 is provided with an other lip spare that moves or rigidity hair row 47 relatively, and it is a V-arrangement curtain structure form.

As shown in figure 11, this lip spare or rigidity hair row 47 can be moved horizontally to a folding position by a slide plate 48, and a folding turn of bilge 49 that stretches out is downwards arranged this moment, and it faces toward hardstand with its apex lines 50, or fully by thereon.

As an example, on its length for the lip spare of banded structure or rigidity hair row 47 is made by elastomeric material in the present embodiment, as plastics.Can also relate to a sealing film or a thin-film member herein.This sealing film can be placed on the base-material of plastics or metal by one or more layers film and constitute.Also possible form is to be equipped with the rigidity hairpencil in the outside of diaphragm seal.(being the degree of depth among the figure) on the width in suction nozzle or suction chamber 15 can stipulate, is equipped with a plurality of fractures on the diaphragm seal, so that have flexible hermetically-sealed construction in good sealing property.

Another preferred construction scheme is that the sealing film is configured to a plurality of segmentations of different materials thickness, therefore exists the flexible part and the part of less flexibility, and can produce bending on the subregion of flexibility.The sealing film can (be the degree of depth) especially and have enough softness districts that for example is essentially straight line in the accompanying drawing on its length.Slide plate 48 is for the motion of diaphragm seal, can be as required mechanically or by one suction nozzle 10 ' on or the power source (as motor 12) settled therein operate.

Can be found out that by concrete structure this lip spare or rigidity hair row 47 are bearing on the slide plate 48 by a segmentation a under the banded structure situation on the one hand, the cross section of this slide plate 48 is strips, and has the structure of shoulder 51.The end face of this shoulder 51 is used to settle lip spare or rigidity hair to arrange the preceding arris of 47 segmentation a, and rigidity hair row 47 rests on the slide plate 48.One is supporting members 52 with slide plate 48 commeasurable structures.This supporting member is preferably not movable.Yet, may supporting member 52 be movable also, and slide plate (support plate) the 48th, the structure setting of fixing.Also may be, not only slide plate 48 but also supporting member 52 all be movable, promptly are the movable structure setting mutually.When clean textile ground, suction nozzle 10 ' inhale chamber 15 with it closely to rest on the fabric floor, simultaneously, brush roll 11 is done pine with dirt, and enters in the fabric ground.By suction nozzle 10 ' rest on the fabric ground, the size in this suction chamber 15 just is defined.Diaphragm seal and lip spare or rigidity hair row 47 be rest on suction nozzle 10 ' one near on the ground side 53, extend on perhaps substantially parallel ground.

Motor 12 and brush roll 11 with transmission device 44 be positioned at overlappingly suction nozzle 10 ' back edge regions.When making suction nozzle 10 ' be transformed into hard floor surface cleaner operation shown in Figure 11, this suction nozzle 10 ' can be raised.But this operation is not with the condition that drops to of diaphragm seal and V-arrangement curtain structure.And latter's (decline of diaphragm seal and V-arrangement curtain) be with suction nozzle 10 ' height and position irrespectively can promote or descend.

Operation slide plate 48, then diaphragm seal suction nozzle 10 ' back edge regions, and sagging bending on its whole width, and make diaphragm seal form the bar bag.Reach hardstand under the formed bag and will inhale chamber 15 in this way and seal up.Suction nozzle 10 ' its excess-three side then in a conventional manner (, not shown) as mechanical system will inhale chamber 15 and seal up.This inhales the sealing of chamber by combination, and it is very little when hardstand operation as shown in figure 11.

The 3rd embodiment of expression in Figure 12 to 18, it has the structure of a floor suction device 43 much at one, only is the V-arrangement curtain structure lip spare of back or rigidity hair row's embodiment difference.

In the zone of ground side a base member 54 is set at dust catcher 43, wherein level is settled the sealing lip 47 of a Y shape curtain structure movably.

It is arris 56 structures of turning of minor radius to sealing lip 47 with a column 55(in addition at the center) be fixedly linked.Other slide block of inserting in base member 54 57 is included in the sealing lip 47 in turn arris 56 or column 55 zones.At the downside of base member 54, promptly a guide channel 58 is set at this base member 54 on the side of cleaning floor, it has the guiding

rib

59,60 that two mutual dislocation are settled.Sealing lip 47 can extend in the guide channel 58 with its free end district at least.

This arris 56 of turning also has a rotating shaft b simultaneously, turns to the position of a decline from the position of a lifting for use in sealing lip 47, and is perhaps opposite.

At slide block 57 is a displacement-type when moving, and this column 55 is rolled on its circumference, and obtains the support of the corresponding torque that produces because of sealing lip 47 change actions and guide channel 58.At this moment, not only displacement but also rotate of sealing lip 47, until arriving a definite terminal location, wherein, it does not only have mechanical stress but also be in the position almost parallel with ground surface to be cleaned still.This position as shown in figure 12.Simultaneously, on this terminal location, treat that clean surface can not make dirty by sealed lip 47 without reason, or can under the condition under the improper action danger, not be cleaned.At this moment, the clean surface does not need to inhale the sealing function in chamber 15.

Can use undersized member (especially slide block 57 and column 55) in this structure of the present invention that shows, thereby have a very little structure height, promptly have only several millimeters.In addition, owing to use the wall thickness of little base member 54 and make its bottom 53 collection direct and dust catcher 43 be one, thereby can realize a very little structure height.The task that this base member 54 has is to protect slide block 57, column 55 and sealing lip 47, and carry out leading, so that avoid the use problem that 43 unsuitable operations cause to the ground dust catcher because of the operator as far as possible.

Figure 15 represents the order that sealing lip 47 stretches out.As seen, by moving of slide block 57, sealing lip 47 will carry out a displacement and rotatablely move.And sealing lip 47 will stretch out in the guide channel 58 constantly.This guiding

arris

59,60 is used to the rotational motion that sealing lip 47 is done around rotating shaft b when sealing lip 47 is done translational motion by means of slide block 57.According to this, sealing lip 47 is turned back to a down position that is used for the hard floor surface cleaner operation from the position of a lifting.Therefore when this position (contrast Figure 14), sealing lip 47 two-side supportings have been guaranteed on the vertical position of hardstand on guiding arris 59,60.Have under enough high flexibility situations at sealing lip 47, just can avoid the damage that when the cleaning hardstand, causes because of dirt particle.Simultaneously, such sealing lip 47 also has a high self-cleaning function.Therefore, add the translation and the rotational motion of sealing lip 47, just can avoid sealing lip 47 to cause the danger of blocking because of accumulating dirt or analog.

Sealing lip 47 for example can be made of plastics.Be divided into many parts because sealing lip 47 (is the degree of depth) in the accompanying drawing on its whole length, therefore improved the flexibility of sealing lip 47.

In addition, the rigidity wool top of a flexibility can also be set without sealing lip 47, it has enough self stability at least, carries out trouble-free lifting or decline to guarantee the V-arrangement curtain structure.

Figure 13 shows the floor suction device 43 in hard floor surface cleaner, as can be seen, and when sealing lip 47 descends, suction nozzle 10 ' preceding edge regions and side area, this flexible rigidity hair-videotape 19 is kiss the earths, and is therefore, sealed to the air distance of small part.But dirt particle can be inhaled in the pumping chamber 15, and their brush rolls 11 of being rotated are intercepted and captured thus, and is sucked air and is transported away.This performability that is positioned at the rigidity hair-videotape 19 of front and side is (mechanical type, figure does not show) realized in a conventional manner.

In addition, with aforesaid may mode the same, will be used for the suction nozzle 10 of hard floor surface cleaner operation ' mention as shown in Figure 13.And, with suction nozzle 10 ' mention and be not to drop to prerequisite with sealing lip 47.On the contrary, the motion of V-arrangement curtain structure, the especially motion of sealing lip 47 can be to realize under the overhead highly irrelevant situation with ground dust catcher 43.

Show among Figure 16 to 18 that the embodiment of above-mentioned the 3rd embodiment in a floor suction device 43 arranges.

The dust collector device 43 that Figure 16 describes comprises 13, one pipe joints 14 of a housing substantially, brush roll of settling in inhaling chamber 15 11 and the transmission device of settling in housing 13 44 that is used to drive brush roll 11.

This floor suction device 43 is equipped with a floor push 17 of settling at pipe joint 14 sides in its zone towards pipe joint 14.

This floor push 17 is placed in the rotating shaft 18 turningly.

Also have, two floor push of settling in belt lacing 14 both sides 17 are provided with as first embodiment.

In Figure 17 and 18, sketched and be used for promoting or decline V-arrangement curtain structure, the especially mechanism of sealing lip 47.V-arrangement curtain structure and another embodiment that makes the slide plate 57 of its motion have also been shown.

Floor push 17 is to be placed on the housing 13 of dust catcher 43 by rotating shaft 18 turningly.One at the one end bearing of settling in the rotating shaft 18 on housing 13, and the other end is bearing in the helical spring 39 on the floor push 17, applies a returning place force that makes floor push 17 be in home position (seeing Figure 17) constantly.One end of on floor push 17, settling Bowden cable 62 by an axle journal 61.This Bowden cable 62 also extends around a gyroscope wheel 63 of settling in case side, on a free end of slide plate 57.Slide plate 57 is a finger in the present embodiment.The free end of slide plate 57 is flexibly to be bearing on the bearing 65 of a case side by compression spring 64, simultaneously, and on home position shown in Figure 17.Because the location of Bowden cable 62, this slide plate 57 should remain on one and make on compression spring 64 position compressed together.

Under situation about floor push 17 being pressed down according to Figure 18,64 of compression springs so launch down in that Bowden cable 62 is lax, and promptly compression spring 64 makes slide plate 57 54 direction moves from supporting base 65 towards base member.At this moment, form the length variations of a V-arrangement curtain structure (it is a sealing lip 47).This point is to realize that so promptly this slide plate 57 is caught the arris 56 of turning of sealing lip 47, and makes sealing lip 47 realize the motion of a lifting in base member 54 owing to moving of slide plate 57 makes sealing lip 47.This point is by being translation-rotational motion realization of V-arrangement curtain or sealing lip 47.

At this moment, floor push 17 is positioned on the depressed position shown in Figure 180.

After the pressure loading on the floor push 17 was removed, it was got back to again on the home position shown in Figure 17.At this moment, it is caused by helical spring 39 spring forces that floor push 17 back rotates, and simultaneously, Bowden cable 62 is by making slide plate 57 overcome the spring force of compression spring 64 and travelling backwards to wheel 63.Slide plate 57 is installed on the arris 56 of turning of sealing lip 47, then makes sealing lip 47 realize the motion of a translation-rotation, thereby cause a descending motion of sealing lip.

For fear of in the upset of inhaling the sealing lip 47 that extends on the 15 whole width of chamber, the grip area of two lips 47 can be set, this point is shown among Figure 16.Be herein, promptly two slide plates 57 roughly grip the arris 56 of turning of sealing lip 47 on two end regions of sealing lip 47, and by Bowden cable 62 and 61 ' it can be moved.If slide plate 57 is placed in the inside of housing 13 so herein, i.e. slide plate 57 relative floor push 17 and be arranged in other vertical plane (seeing the slide plate on Figure 16 left side), so just must be provided with at least an other deflecting roller 63 '.

Also can be susceptible in this embodiment, the V-arrangement curtain structure is arranged to brush bar, and the bristle of brush bar has enough rigidity, so that guarantee a glitch-free process when operation floor push 17.

The possible mode of Cun Zaiing is in addition, except structure is the V-arrangement curtain that moves of sealing lip 47 forms, one or more other static V-arrangement curtain structures also can be set as described, for example can be the brush bar, they be placed in front and its side of inhaling chamber 15 on the traffic direction of floor suction device 43.

Figure 19 to 24 expression another one embodiment.

The floor suction device of in Figure 19, representing 43.It is the same with aforesaid embodiment, be provided with one separate be the drive unit 12 of motor form, it drives brush roll 11 by a transmission device 44, and brush roll 11 also be provided with brush row 11 '.This dust catcher 43 is basically by 13, one pipe joints 14 of a housing, and as aforementioned, brush roll of settling in inhaling chamber 15 11 and electric driver 12 are formed.

This dust catcher 43 is provided with a floor push 17 of settling at pipe joint 14 sides in its zone facing to pipe connections 14.

At the side of floor push 17 with three functional indicator lights 66～68 are set in housing 13, each indicator lamp all with signal indication dust catcher 43 by floor push 17 adjustable methods of operation.

Basically, these floor suction device 43 different methods of operation are to realize by two switches of settling up and down, wherein the switch of a top of floor push 17 expressions.The switch of this top or floor push 17 are the axles on 18 that are placed in the casing side turningly.The switch 69 of the plate shape that this is following is placed in casing 13 inside, and fixedlys connected at the rotatable bar of settling 70 of case side equally with one at this antitorquely.Following switch 69 is placed in its structural configuration is in the casing 13, promptly this switch is lived by the switch (being floor push 17) of top is topped herein.

This following switch 69 is to elastic bearing to casing 13 or on the near-earth side 53 by a compression spring 71.

The switch of this floor push 17 or top that is to say to have an operation axle journal 73 on the side of case side at its lower side, by it, this following switch 69 just can be operated by the switch 17 of top.

In addition, two contact-making

switches

74 and 75 are set in casing 13, the operation of brush (roller) are switched on or switched off by them.

Herein, contact-making switch is so to settle, and promptly this switch always is in a home position by the lower side imposed load of the switch of top or floor push 17, that is the inoperation state of floor push 17.If when the switch of this top or floor push 17 were gentlier (not big resistance) operation, then the downside of the switch of top or floor push 17 just left contact-making switch 74.Therefore, switch 74 just sends on a signal to the not shown electronic component, so that the operation of brush (roller) is switched on or switched off.For example, floor push 17 slight operation can realize the disconnection that brush (roller) moves.So, after this under the situation of next operation floor push 17, this brush (roller) operation is just connected again.

This mentioned its on settled the rod member 70 of following switch 69 almost to extend on the whole width of inhaling chamber 15, and have nodular zone 76 centre, the U-shaped bending, so that transmission device 44 passes through.In addition, rod member 70 is downward in its end region, that is to say be equipped with crooked L shaped end region 77 on the direction of the bottom side 53 of casing 13.

On the nodular zone 76 of the U-shaped bending at rod member 70 middle parts, be fixed with Bowden cable 62, its another free end of deflecting roller 78 usefulness and a rigidity wool top 19 that it is settled by a casing side join.This rigidity wool top 19 is structures of V-arrangement curtain, and flexibly is bearing on the casing 13 by compression spring 21 and 22.Simultaneously, this

compression spring

21 and 22 applies a lasting load with the direction towards ground to be cleaned to rigidity wool top 19.On the home position of Figure 20, this rigidity wool top 19 or V-arrangement curtain device be by the pulling force opposite with the elastic load effect of

compression spring

21 and 22 of Bowden cable 62, and remain on the position of mentioning or on a position of inserting in the casing 13.

Settling rotating its on the end region 77 of the L shaped bending of rod member 70 respectively is that this gripping arm 79 configurations on end regions 77 of gripping arm of slide plate 57 forms can use the syndeton of binding post (folder) to realize.

This gripping arm 79 stretches in the base member 54 of settling on casing 13 bottom sides 53 with its free end.This base member 54 is to set up by the base plate 81 of the cover piece 80 of a casing side and a removable casing 13.

The free end of each gripping arm 79 is provided with the receiving member 82 of an arc section shape, wherein is mounted with a column 55 of the curtain structure of arris 56 forms of turning rotationally.On column 55, not in the center and phase countershaft b fix a sealing lip 47.The free end of sealing lip 47 stretches in the guide channel 58, and sealing lip 47 is the V-arrangement curtain structure, and guide channel 58 is made of two guiding

arris

59 and 60, and two arris dislocation is simultaneously settled.Thus, guiding arris 59 is that a fluting by base plate 81 constitutes, and guiding arris 60 is to form by a corresponding fluting in casing 13 bottom sides 53.

In base member 54, can do translation and arrangement rotationally by the V-arrangement curtain structure that sealing lip 47 and column 55 are formed.

Following switch 69 has the locating journal 83 that a side direction is settled, it on home position shown in Figure 20, holding in the guide channel 84 of a setting element 85, and setting element 85 is to place the casing side rotationally and bear spring load.

Following switch 69 its downsides are equipped with a latch plate that extends laterally 86, and it is when the home position of Figure 20, to contact-making switch 75 imposed loads of having mentioned.

When if the light pressure of floor push 17 in Figure 21 further done powerful the operation, so, carry out load like this by 73 pairs of following switches 69 of operation axle journal of settling on top switch or the floor push 17, promptly should bottom's switch 69, under the prerequisite of guide channel 84 mating reactions of locating journal 83 and setting element 85, leave setting element 85 and be turned back on the position of a high commentaries on classics shown in Figure 23.Simultaneously, the spring 86 of following switch 69 leaves contact-making switch 75, thereby brush roll is driven disconnection.This disconnection that this brush roll drives be what to have nothing to do in the top contact-making switch 74 last signals that send.

Following contact-making switch 75 can for example be realized an interruption that the electric current of the resistance drive unit 12 of brush roll 11 is carried.This top contact-making switch 74 for example can send when each operation on a signal to the electronics upset level, to be used for being switched on or switched off of motor 12 in contrast.

Except the disconnection effect to brush roll, the high position of this bottom's switch 69 rotation also can realize the deflecting action of the end regions 77 of the zone 76 of U-shaped bending of a rod member 70 and L shaped bending.On the one hand, can cause the bending of a Bowden cable 62 like this, thereby

compression spring

21 and 22 makes rigidity wool top 19 be displaced to the position of a decline.On the other hand, the end regions 77 of this L shaped bending is done so to move, and promptly by the gripping arm of settling 79, makes V-arrangement curtain structure (being the form of sealing lip 47 herein) do translation and rotational motion in base member 54 thereon.Therefore, make sealing lip 47 drop to a position that becomes perpendicular positioning with hardstand to be cleaned.

Sealing lip 47 has a sufficiently high flexibility, according to this, because the damage to the crust that will clean that dirt particle causes just can have been avoided.In addition, such sealing lip 47 also has a high self-cleaning property.Therefore, combine, just make sealing lip 47 avoided because of building up the jammed danger of dust and dirt dirt with the translation-rotation of sealing lip 47.

As long as the following edge regions of base member 54 is made of base plate 81, V-arrangement curtain structure, the especially replacing of sealing lip 47 just become possibility so., can for example unclamp bolt herein, thereby the receiving member 82 of base member 54 and gripping arm 79 can pick and place freely all from base plate 81 being pulled down from casing 13 with the simplest mode.By this frame mode, can also realize the cleaning of base member 54.

As aforesaid embodiment, in above-mentioned organization plan, this V-arrangement curtain structure, rigidity wool top 19 and sealing lip 47 can be carried out a motion that has nothing to do with dust catcher 43 height above ground level.The operation of overhead highly always passing through to describe among the figure of floor suction device 43 is taken turns not given.

The corresponding running status of floor suction device shows by functional indicator light 66～68.Can stipulate a kind of brush roll operation of these function lamp 66～68 indications and suction operation with an electronic switching circuit.There is

identical intension switch

17 and 69 position among this point and Figure 20, wherein Xia Bian switch 69 remains on the position of a decline, simultaneously locating journal 83 part 85 that is positioned is intercepted and captured, and sends one by the switch 17 of top by contact-making switch 74 and be used to connect the signal that brush roll moves.After slightly operating floor push 17 by Figure 21, then cause an effect that makes the electric driver disconnection of brush roll 11 by contact-making switch 74, this function lamp 66 extinguishes.At this moment, be used to have only the new running status of suction operation by 67 indications of function lamp.If the V-arrangement curtain structure is logical make floor push 17 pressing down of brute force and descend, and the motor of brush roll 11 is disconnected thus, and this running status is by 68 indications of function lamp so, and the while is according to the running status of front, not being that function lamp 66 extinguishes, is exactly that function lamp 67 extinguishes.
