Technical field

The present invention relates to a kind of for the cleaning wiping cloth of sticking on cleaner suction nozzle.

Background technology

Cleaner suction nozzle is known.It is especially applied in for suction process floor as attachment device, the domestic vacuum cleaners of carpet surface or hard floor.In addition, be also known for other surface-treated suction nozzle.This suction nozzle is connected with dust catcher by a suction hose or analog usually, so that the object that suction position is higher, and such as bookshelf surface or similar place.During operation, there is the negative pressure that can keep cleaning wiping cloth in the suction inlet region of cleaner suction nozzle.Correspondingly, the cleaner suction nozzle of batch production like this can be used for the special hard surface of wiping, such as timber floor or stone floor.

Summary of the invention

In view of aforesaid prior art, technical problem to be solved by this invention be construct with improvement a kind of for the cleaning wiping cloth of sticking on cleaner suction nozzle.

This technical problem solves thus, that is, cleaning wiping cloth has a sealant.

In the combination of a kind of cleaner suction nozzle and cleaning wiping cloth, cleaner suction nozzle has a suction inlet, and cleaning wiping cloth preferably remains on suction nozzle by negative pressure.Cleaning wiping cloth has the sealant for preventing from sucking liquid.Due to this structure, also can wet rubbing surface by means of cleaner suction nozzle.The improvement of cleaning effect is realized by wet-cleaning.For avoiding Clean-liquid by being absorption cleaning wiping cloth and preferably required suction air flow enters cleaner suction nozzle, and arrive the dust catcher producing suction airstream via this suction nozzle, described cleaning wiping cloth is equipped with a sealant.Sealing layer plays separate layer.

Below introduce other expansion design feature of the present invention.They both can as the preferred addition feature of the above-mentioned technical solution of the present invention, but itself also tool invention be worth.Therefore, regulation in the further developing of present subject matter, cleaner suction nozzle has the suction channel branch separated that two are positioned at cleaning wiping cloth upstream, and a sticking negative pressure for sticking cleaning wiping cloth, another then aspirates for direct floor.The suction air flow that this structure produces when making to run is separated in suction nozzle side, be used for fixing cleaning wiping cloth on the one hand, then aspirate for direct floor on the other hand, wherein, further when arranging one and preferably covering maintenance suction channel branch completely towards the cleaning wiping cloth in the hole on floor, the cleaning wiping cloth of attaching troops to a unit in maintenance suction channel branch keeps chamber at least to form the enclosure space that almost comprises separately negative pressure.Improve the dynamic pressure in whole system by flowing velocity relatively high during suction operation, then reduce static pressure on the contrary.The wall of less static pressure in flow channel causes suction, and in the current situation, is also just equivalent to keep causing suction in chamber in the cleaning wiping cloth closed when adsorbing cleaning wiping cloth.This is produced by the static pressure that is less than surrounding air static pressure.Cleaning wiping cloth keeps the negative pressure in chamber to be preferred for the negative-pressure adsorption of cleaning wiping cloth.Pass through the separation of advised suction channel branch, in each region that cleaning wiping cloth keeps chamber, give uniform negative pressure.Correspondingly, the pressure that effect one is identical on cleaning wiping cloth total negative pressure loading surface.In addition, the suction channel branch by separating obtains favourable pumping power in suction suction channel branch.Pumping power also can not reduce to be adsorbed on suction nozzle due to suction cleaning wiping cloth.

In preferred design, from vertical direction, at least Local Phase is folded extends with arranging in suction channel branch, therefore, suction channel branch bottom suction nozzle on projection in or in projection when running on pending floor, at least local is overlapping.In preferred layout, maintenance suction channel branch extends below suction suction channel branch, wherein, in maintenance another design with suction channel branch, straight forming cleaning wiping cloth keeps chamber simultaneously, and suction suction channel branch is such as pipeline section shape, be positioned at above maintenance suction channel branch, and in side a shaping nozzle-like suction inlet, this suction inlet preferably extends past the width of whole suction nozzle transverse to usual moving direction further.The suction inlet of attaching troops to a unit in suction suction channel branch is preferably arranged on the front area of suction nozzle relative to the usual moving direction of suction nozzle, so that when suction nozzle travels forward on common direction, before floor is by cleaning wiping cloth wiping, just pick up thicker dirty particles.

Therefore, specify further, suction channel branch at least local is adjacent to extend in the horizontal direction, extends further in the horizontal direction relative to usual moving direction.Therefore, such as be positioned at above bottom suction nozzle, further with keep closely spaced bottom suction nozzle, level towards plane not only keep chamber crossing with the cleaning wiping cloth of maintenance suction channel branch, also and common moving direction be arranged on the suction suction channel branch before it suction inlet intersect.

Cleaning wiping cloth region is designed for by one in the horizontal direction further preferably and is bearing in sealing lip on floor and floor suction areas separates.Sealing lip extends transverse to the common moving direction of suction nozzle in preferred design, extends past suction nozzle further transverse to the whole width that common moving direction is observed.This layout mainly avoids preferably wetting cleaning wiping cloth to become dry due to the suction air flow of aspirating through floor suction areas.Due to this layout of sealing lip, air suction is at least limited in the suction nozzle region usual moving direction is retained in before sealing lip, wherein, preferably also arranges such sealing lip in the side of floor suction areas further.In addition, through threshold or other flat barrier, sealing lip is also used as favourable servicing unit.If suction nozzle moves forward on usual direction, that is, first suction areas moves on to the top on pending floor, so, the free end area of sealing lip be located on moving direction immediately preceding after the institute of cleaning wiping cloth attach troops to a unit on edge, or cover at least one gap that may be formed between cleaning wiping cloth and suction nozzle bottom surface alternatively.Thus avoid cleaning wiping cloth be torn through threshold or other flat barrier or peeling off.Sealing lip paves cleaning wiping cloth transiently, makes it clear the jumps.

In another kind design, preferably as fixing the supplementing of negative pressure, cleaning wiping cloth is remained on suction nozzle by mechanical device.This machinery is fixedly particularly useful for supporting that the negative pressure of cleaning wiping cloth is fixed.Therefore, by placement of mechanical holding device, even if when suction airstream is such as closed due to device and interrupted, cleaning wiping cloth can also continue to be adsorbed on suction nozzle.In one design, mechanical device is made up of a magic tape or fastener, and wherein, a fastener is attached troops to a unit in cleaning wiping cloth, and another corresponding with it fastener is attached troops to a unit bottom suction nozzle or the support component of cleaning wiping cloth.When cleaning wiping cloth is designed to be made up of a special textile material, when being such as made up of nonwoven cloth material further, this material itself is shaped to the magic tape of ring-type, and arranges a barb-like corresponding magic tape in device side.Further alternative, mechanical device is buckling and locking device, such as this type, that is, be designed with the kayser latch of an elastic construction if desired in device side, its latch hole acting in conjunction corresponding with cleaning wiping cloth.Strengthen latch hole edge in case with during the acting in conjunction of kayser latch reliably kayser keeps, such as by be integrated in cleaning wiping cloth sealant realization.

In order to increase in maintenance suction channel and the negative pressure in the cleaning wiping cloth maintenance chamber of cleaning wiping cloth of attaching troops to a unit, specifying in the one of present subject matter further develops, there is flow channel constriction in the upstream of cleaning wiping cloth in maintenance suction channel.This flow channel constriction achieves the increase of this region flow velocity, and this causes the rising of negative pressure in the cross-sectional expansion region of cleaning wiping cloth chamber.Flow channel constriction plays Venturi tube-suction nozzle.In another preferably designs, flow channel constriction designs in the bifurcation region of Liang Ge flow channel branch, but, alternatively, the upstream of the cleaning wiping cloth before bifurcated also can be designed.

For preventing the dirty particles transmitted by suction suction channel branch from entering maintenance channel branch, specify further, the latter passes through separating element and the suction channel of a filtration members type, especially separates with suction suction channel branch further.It is have the ply of paper of filtering characteristic or the filter element of non-woven fabrics that the separating device of filtration members type is preferably a form.Separating device also can be formed by the aperture plate closely interweaved alternatively.In another kind design, the separating device of filtration members type can be changed, and is preferably arranged in the bifurcation region of Liang Ge flow channel branch.

On the usual moving direction of suction nozzle, construct the entrance of a suction suction channel branch in the front and back of cleaning wiping cloth, this structure is proved to be particularly advantageous.Correspondingly, no matter with before pending floor contact or after contacting, the direct floor suction on usual direction is all realized by cleaning wiping cloth.This is proved to be favourable when common suction nozzle operation, because, connected dust catcher can be passed through at this suction nozzle to move forwards or backwards in the usual manner, and thus have a suction channel branch to be arranged in the direction of movement before cleaning wiping cloth for aspirating floor all the time.If suction suction channel branch bifurcation is a rear portion suction suction channel branch and an anterior suction suction channel branch, in this correlation, be proved to be favourable further.

In the further preferred arrangements of the sealing lip for separating cleaning wiping cloth region and floor suction areas, in conjunction with the bifurcated of suction with suction channel branch, if the entrance of the entrance of front floor suction areas and rear floor suction areas is designed for by one in the horizontal direction and is bearing in sealing lip on floor and cleaning wiping cloth region separation, be proved to be favourable further.Correspondingly, each cleaning wiping cloth edge being in side on respective moving direction is configured with a sealing lip, and sealing lip protection floor suction areas preposition does not in the direction of movement affect by cleaning wiping cloth.Also make thus on two moving directions, to cross flat barrier, as threshold becomes easy.At this, sealing lip prevents cleaning wiping cloth from extracting bottom suction nozzle or peeling off effectively.Therefore specify further, sealing lip is designed to overturn by moving movement, wherein, in the travel direction of sealing lip flip portion, the suction inlet of the floor suction areas configured is closed substantially, and on same direct of travel, another sealing lip of attaching troops to a unit in other floor suction areas only acts on dividually with cleaning wiping cloth.Such as when suction nozzle moves up common side, that is, when dust catcher moves forward usually, the sealing lip reclined with cleaning wiping cloth of front side suction channel overturns towards cleaning wiping cloth, and cover pump orifice at edge side, flat barrier can be crossed more easily, as threshold thus.In the direction of movement relatively the rear sealing lip placed of cleaning wiping cloth by the relative movement relative to pending floor to the suction inlet of attached troops to a unit floor suction areas automatic turning, and substantially close this suction inlet completely, thus on selected moving direction, whole suction force concentrates on front side and carries out floor suction.When suction nozzle moves backward, the state of sealing lip changes, and therefore, whole suction force concentrates on device profile suction road below afterwards.

During for guaranteeing to lift suction nozzle from clean floor, may for wet and thus become heavy cleaning wiping cloth and can continue to be fixed on suction nozzle, in maintenance suction channel branch, design a negative pressure strengthen, this negative pressure is strengthened realizing preferably by the reduction of the cross section of floor suction areas suction entrance.Therefore, once suction nozzle lifts, just can close floor suction areas completely or reduce cross section.The suction closedown of entrance or the reduction in its cross section can be controlled by mechanical organ.Therefore, correspondingly specify, the button whether suction nozzle lifts by detecting floor contact is determined.In common floor-cleaning, this button detects floor to be cleaned.Suction entrance is opened completely, and acts on the enough large of the negative pressure selection in cleaning wiping cloth.Do not have and floor contact if button detects, so mechanically, will can reduce by the assessment of push button signalling the cross section aspirating entrance electrically if desired yet, thus improve the negative pressure of cleaning wiping cloth holding chamber indoor.The preferably closed-suction passage when suction nozzle lifts from floor, this further by machinery, realize with the coefficient device of button, such as rotatable lid or analog.

Regulation in the further developing of present subject matter, that is, cleaner suction nozzle is configured with the one or more recessed channel or the groove that are communicated to suction inlet, and, design one makes recessed channel be retained to that small part is opened, simultaneously ventilative structural member, for being arranged between cleaning wiping cloth and suction nozzle.At this, the recessed channel constructed such as extends transverse to the common movement of cleaner suction nozzle or the direction of motion, in addition, and if desired also can in the direction of movement or extension in an acute angle with it.Such as, the recessed channel of multiple such structure can from suction inlet until arrive the end face of cleaner suction nozzle.By these recessed channel, the suction process on floor just can be realized in the usual manner in conjunction with the suction nozzle be attached thereto.When wiping works, at least one recessed channel is equipped with structural member, and this structural member makes recessed channel be retained to small part and open when near treated side.Structural member is correspondingly for providing a supporting surface by the cleaning wiping cloth of recessed channel tensioning.By to partially open and corresponding ventilative structure continues to realize the absorption of cleaning wiping cloth under condition of negative pressure.The recessed channel of preferred cleaner suction nozzle possessive construction arranges such structural member when wiping runs.Have in the design of maintenance suction channel branch separately and suction suction channel branch a kind of, structural member covers the whole SS of maintenance suction channel branch towards floor in preferred design.

Structural member is a working of plastics that can insert suction nozzle from below in preferred design, be so a kind of working of plastics furtherly, that is, it preferably covers the recessed channel of possessive construction, and also preferably cover suction nozzle further in addition, this partially opens recessed channel and/or the suction inlet towards treated side further.Structural member can be correspondingly a plastic injection piece, and this moulding is further by be fixedly clamped or kayser is fixedly fixed on the bottom side of cleaner suction nozzle.In addition, structural member such as also can design with the insert that can coordinate with cleaner suction nozzle grafting integratedly, and this insert forms suction inlet and recessed channel.The layout of structural member is preferably selected further like this, that is, this structural member struts an at least almost common plane with the suction inlet floor area adjacent to the recessed channel constructed or cleaner suction nozzle sticking channel part section in an inserted condition.Alternatively, structural member also can be the basic module of cleaner suction nozzle, such as, by switching movements or pressing movement dismounting.Therefore, can such as use pin master cock when needed, make structural member pass through decline immigration structure recessed channel and move into suction nozzle if desired.In addition, the wiping edge of definition also can be formed in principle by structural member.For partially opening structural member, it is equipped with suction through hole.This through hole can be designed as incision-like or boring shape, and at its elementary contour exposed and quantitatively select like this, that is, makes the also negative pressure maintenance more reliably when wiping work of configured cleaning wiping cloth.

Cleaning wiping cloth is directly fixed on structural member in a kind of preferred structure of theme.Specify alternatively, an intermediate layer is set between structural member and cleaning wiping cloth.This intermediate layer can be coating, and to be anti-skidding material or form be such as form by this kind of layer that to be adsorbed on the material in cleaning wiping cloth because friction increases better and to make.This cleaning wiping cloth remains on the position under cleaner suction nozzle better in the processing procedure of floor according to its structure.Therefore, specify in one further develops, intermediate layer is made up of the foamed material of embossing.

In this case, intermediate layer is also for auxiliary positioning.In addition, the absorption of cleaning wiping cloth is also enhanced.For vibration damping on such as uneven floor, preferably specify further, this intermediate layer is flexible adjustment, and such as, intermediate layer by being made up of foamed material realizes.The intermediate layer of flexible adjustment can realize the balance of floor unevenness (such as slabstone seam) by this, realize cleaning wiping cloth thus and at least almost comprehensively support on floor to be cleaned.In addition, optionally, the intermediate layer always towards cleaning wiping cloth is made up of silicones, and be made up of silicone coatings or similar anti-skidding material further, described coating is on structural member.

The another kind that cleaning wiping cloth is adsorbed when cleaner suction nozzle runs is improved and is realized by the airtight construction of sealant.In the one design of present subject matter, sealant extends past the whole surface of cleaning wiping cloth.Alternatively, this is advised further, formed sealant region sealant only partial design in cleaning wiping cloth.At this, sealant region is especially configured in the region that structural member applies negative pressure, is especially configured in further on the suction inlet of recessed channel or cleaner suction nozzle, keeps reliably to realize cleaning wiping cloth by negative pressure loading.

Be proved to be especially favourable structure as a kind of, wherein, cleaning wiping cloth has a kind of profile, and the elementary contour of this profile and suction nozzle matches or at least almost matches completely with it.Create thus most possibly by the wiping surface of cleaner suction nozzle load.Prerequisite is, cleaning wiping cloth is fixed on suction nozzle by means of only negative pressure, such as, can abandon using other clamping element for fixing cleaning wiping cloth or analog.Correspondingly there is a kind of cleaning wiping cloth with wiping surface, the optimised gross area ground of this wiping surface uses.

In the most simply designing, cleaning wiping cloth can be dry fabric.Liquid for wet processed floor is directly coated in floor in this case, and by be distributed in be equipped with cleaning wiping cloth suction nozzle on work.In the one of present subject matter further develops, cleaning wiping cloth is wet fabric, and this wet fabric is correspondingly for moistening and be equipped with cleaning agent if desired.In the design substituted, cleaning wiping cloth also can be equipped with sealing device or analog.Continue pending hard floor to be drenched with controlling by wet fabric.The sealant be arranged in cleaning wiping cloth prevents moistening cleaning wiping cloth because of suction exsiccation.

Preferred effect realizes thus further, that is, suction nozzle has sucker when structural member inserts and cleaning wiping cloth is fixed in front surface region.Sucker on front side of this keeps unimpeded by structural member, preferably further to extend above wiping cloth cover, therefore, in the wiping processing procedure of carrying out by means of cleaner suction nozzle, before being positioned at the more coarse dirty particles arrival cleaning wiping cloth before suction nozzle, they can be picked up.Extend the service life of cleaning wiping cloth thus.Cleaning wiping cloth can not be made dirty by coarse particles or even damage.Combine unlike this or therewith, sucker also can be arranged on side or be arranged in device region below.

Especially in order to improve the negative pressure in possible suction areas further, specify in one further develops, sucker is configured with a sealing lip.Sealing lip is such as made up of flexible plastic or elastomeric material.According to this structure, also can realize the increase of suction function in cleaning wiping cloth, thereby enhance the absorption of cleaning wiping cloth on structural member, and strengthen absorption affinity further by sucker.

Cleaning wiping cloth can be configured to multilayer, such as, have the sealant that a cleaning layer is disposed thereon with, be fixedly connected with cleaning layer.In the further developing of present subject matter, sealant is made up of film, is especially made up of plastic sheeting further, described film correspondingly waterproof and also preferably airtight further.The wiping of cleaning wiping cloth has active layer to be a non-woven fabrics in preferred design, such as PP-non-woven fabrics or PE-non-woven fabrics, in addition, be microfibre non-woven fabrics if desired in the nonexpondable situation of cleaning wiping cloth possibility.

Fixing cleaning wiping cloth substantially plane earth, extend abreast with pending floor level.If desired, especially can design the wiping edge in cleaning wiping cloth on corresponding structural member, which increase the scraping effect of cleaning wiping cloth on floor.

Pass through advised scheme, create aspirator/wiping arrangement that a kind of form is cleaner suction nozzle, it especially makes wholesomely cleaning wiping cloth to be installed on cleaner suction nozzle to become possibility, and also makes wholesomely to remove cleaning wiping cloth in addition and become possibility.For being arranged on cleaner suction nozzle by cleaning wiping cloth, user does not need the tactile cleaning wiping cloth that catches.But so just enough, that is, the preferred profile of cleaner suction nozzle being equipped with structural member is positioned in cleaning wiping cloth in the same manner, and is connecting dust catcher afterwards.The suction air flow now entered causes the negative-pressure adsorption of cleaning wiping cloth.By closing dust catcher, cleaning wiping cloth drops, thus such as directly falls into one in the container removed.

In another further develops, be optimize the location of cleaning wiping cloth on suction nozzle, make the coverage rate of cleaning wiping cloth have a texture structure, such as form is protrusion-texture structure, this structure corresponding to suction nozzle bottom side recessed-texture structure matches.Which ensure that cleaning wiping cloth is accurate below suction nozzle, fit and can avoid sliding in processing procedure fixing.This structure is only arranged on the side of cleaning wiping cloth.Effective cleaning layer does not affect by it.

Also specify, cleaning wiping cloth at least arranges at least one edge with standing part in regional area, realizes cleaning wiping cloth thus and remains on better on structural member.This standing part is designed by suction in an advantageous manner and fixes.Therefore, specify in the design of example, at the usual moving direction of suction nozzle, partial design before cleaning wiping cloth and/or below has a standing part, and the front area at suction nozzle or structural member or the Background Region of this partial response are inhaled into or aspirate.According to this structure, the cleaning wiping cloth so kept can operationally be located relative to the invariant position under structural member.

Standing part as one man designs with cleaning cloth material in one structure, and this has one further if desired for improvement of the sealant aspirated.In addition, although standing part material is consistent, but it has structurally done change.Therefore standing part can have higher density in the effective region of cleaning wiping cloth wiping relatively, is equipped with plastic coating where necessary further.Thereby produce the edge of hard or tabular to form standing part, wherein, in this connecting each other, also there is such possibility alternatively, that is, standing part is formed by duroplasts, the duroplasts-edge of injection moulding that to be such as form be further.By this firmly or the surrounded by edges suction nozzle of tabular or the forward edge of structural member and/or posterior edges, wherein, this encirclement is realized by the negative pressure in suction areas.In addition, the front side of suction nozzle also can be made to aspirate towards the floor that will clean according to this structure, for this reason, in the one design of standing part, have through hole further, this through hole forms the sucker towards floor.

Standing part at least almost extends abreast with the wiping live part plane of cleaning wiping cloth in the respective design of the edge suction of structural member and front side and/or rear side.When structural member-surrounded by edges, the standing part of the cleaning wiping cloth of maintenance is positioned at one from the bending plane of effective cleaning layer plane extended spot, and such as bending one until the angle of 90 degree.

In addition, the present invention relates to the cleaning wiping cloth of a kind of sticking on cleaner suction nozzle.In order to construct such cleaning wiping cloth with improvement, a sealant is set.Sealing layer prevents from when cleaning wiping cloth is configured on cleaner suction nozzle having aspirated liquid by cleaning wiping cloth.Correspondingly, the cleaning wiping cloth of so batch production also may be used for the wet-cleaning undertaken by cleaner suction nozzle, and wherein, the fixing negative pressure by means of only when dust catcher run formed of cleaning wiping cloth on cleaner suction nozzle realizes.

In addition the present invention also provides some features as described below, and they preferably combine with the technical scheme of claim 47, but also can only be combined with the Partial Feature of claim 47 scheme in principle, states even individually also to have an invention meaning.Another improvement of the absorption of cleaning wiping cloth when cleaner suction nozzle runs is realized by the design that sealant is airtight.

In another design, cleaning wiping cloth has such device, and this device is preferably supplemented by fixing on suction nozzle of negative pressure cleaning wiping cloth.These preferred mechanical devices are particularly useful for supporting that the negative pressure of cleaning wiping cloth is fixed.Therefore, by arranging mechanical holder, cleaning wiping cloth when suction air flow is interrupted, such as, is closed due to device and is caused having no progeny in suction airstream, can also continue to remain on suction nozzle.In one design, mechanical device is made up of magic tape, and wherein, a magic tape is attached troops to a unit in cleaning wiping cloth, and another corresponding with it magic tape is attached troops to a unit bottom suction nozzle or attaches troops to a unit in the support component of cleaning wiping cloth.When cleaning wiping cloth is made up of a special textile material, when being such as made up of nonwoven cloth material further, these materials itself form the magic tape of ring-type.Further alternative, mechanical latch device, such as this type, that is, be designed with the kayser latch of an elastic construction if desired, its latch hole acting in conjunction corresponding with cleaning wiping cloth in device side.Strengthen latch hole edge in case with during the acting in conjunction of kayser latch reliably kayser keeps, such as by be included in cleaning wiping cloth sealant realization.

Be proved to be especially favourable structure as a kind of, wherein, cleaning wiping cloth has a kind of profile, and the elementary contour of this profile and suction nozzle matches or at least almost matches completely with it.Create thus most possibly by cleaner suction nozzle load ground wiping surface.Prerequisite is, cleaning wiping cloth is fixed on suction nozzle by means of only negative pressure, such as, can abandon using other clamping element for fixing cleaning wiping cloth or analog.Correspondingly there is a kind of cleaning wiping cloth with wiping surface, the optimised gross area ground of this wiping surface uses.

In the most simply designing, cleaning wiping cloth can be dry fabric.Liquid for wet processed floor is directly coated in floor in this case, and is distributed in by wiping action and is equipped on the suction nozzle of cleaning wiping cloth.In the one of present subject matter further develops, cleaning wiping cloth is wet fabric, and this wet fabric is correspondingly moistening and is equipped with cleaning agent if desired.In the design substituted, cleaning wiping cloth also can be equipped with sealing device or analog.Continue pending hard floor to be drenched with controlling by wet fabric.The sealant be arranged in cleaning wiping cloth prevents moistening cleaning wiping cloth from becoming dry because of suction.

Cleaning wiping cloth can be configured to multilayer, such as, have the sealant that a cleaning layer is disposed thereon with, be fixedly connected with cleaning layer.In the further developing of present subject matter, sealant is made up of film, is especially made up of plastic sheeting further, described film correspondingly waterproof and also preferably airtight further.The wiping of cleaning wiping cloth has active layer to be non-woven fabrics in preferred design, and such as PP-non-woven fabrics or PE-non-woven fabrics in addition, are microfibre non-woven fabrics when cleaning wiping cloth may repeatedly use if desired.

At this, sealant constructs so airtightly, even if make the negative pressure near suction nozzle side also can guarantee when its numerical values recited changes by systematic influence to adsorb reliably for cleaning wiping cloth and keep.Now sealant is waterproof, thus make can by the water yield more than a limit, will family expenses-dust catcher common on the market can not be caused damage once exceed this limit.In this sense, sealant need not positive confinement, is also such as made up of enough dense non-woven fabrics, and the optional film by being sprayed on coating on wiping non-woven fabrics or not exclusively sealing realizes.

Cleaning wiping cloth can infiltration water and/or cleaning agent and/or bright cleanser and/or polishing agent.Also the various cleaning wiping cloth type adapted with cleaning course can be had, such as a kind of type for wiping and a kind of type for polishing.

In the one by present subject matter designs, sealant extends past the whole surface of cleaning wiping cloth.Alternatively, this is advised further, formed sealant region sealant only localized design in cleaning wiping cloth.

Also specify, cleaning wiping cloth is at least provided with standing part in the regional area at least one edge, realizes cleaning wiping cloth thus and remains on better on cleaner suction nozzle.Standing part is designed by suction to realize in an advantageous manner to be fixed.Therefore, specify in the design of example, that is, at the usual moving direction of suction nozzle, partial design before cleaning wiping cloth and/or below has a standing part, and this partial response ground can be inhaled at the front area of suction nozzle or structural member or Background Region or aspirate.

Standing part as one man designs with cleaning cloth material in one structure, and this has one further if desired for improvement of the sealant aspirated.In addition, although standing part material is consistent, but it has structurally done variation.Therefore standing part can have higher density in the effective region of cleaning wiping cloth wiping relatively, is equipped with plastic coating where necessary further.Thereby produce the edge of hard or tabular to form standing part, wherein, in this connecting each other, also there is such possibility alternatively, that is, standing part is formed by duroplasts, the duroplasts-edge of injection moulding that to be such as form be further.Especially by suction, with this firmly or the surrounded by edges suction nozzle of tabular or the forward edge of structural member and/or posterior edges.Alternatively, also can realize the fixing of machinery by standing part, such as, clamp.Standing part another kind design in there is through hole, this through hole is formed towards the sucker on floor.

In one design, cleaning wiping cloth infiltrates clean liquid, is clean active principle further, as surfactant.Correspondingly, cleaning wiping cloth is being configured in the liquid wet-cleaning floor that directly just can be held by sustained release after on cleaner suction nozzle.Alternatively, effective cleaning layer of cleaning wiping cloth can have preservation clean liquid and the miniature capsule opened by pressure.This miniature capsule is arranged on effective cleaning layer with designing laminate in the one of present subject matter.Preserve clean liquid in each miniature capsule, as water, add cleaning action agent if desired.During use, miniature capsule is split by the pressure in cleaning wiping cloth, and described pressure is applied by cleaner suction nozzle.Liquid in miniature capsule is released, and just correspondingly wetting cleaning wiping cloth in use, and wherein, cleaning wiping cloth is imbitition first, so as afterwards constantly releasing liquid be used for wet-cleaning.

In present subject matter a kind of further develops regulation cleaning wiping cloth by wet, the paper material of multilayer makes, wherein, moisture or obtained by the infiltration that cleaning wiping cloth is preserving position, or to break just acquisition due to set miniature capsule.Because cleaning wiping cloth is made up of multi-ply paper, the optional particle by being formed at self-stabilization layer when moisture loads is formed, and thus can realize the removing of cleaning wiping cloth after completing wet-cleaning.Cleaning wiping cloth, when drying, promotes further by the friction requirements in wiping motion process, is split into multiple fritter via cleaner suction nozzle, these fritters can by existing, also can be that the withdrawing air of extra access flows through cleaner suction nozzle and is sucked.At this, select when dividing the size of cleaning wiping cloth fritter, need the size of the suction flow orifice considering reservation.Cleaning wiping cloth is made to be decomposed into the single fritter of dust size or grain size by division.When cleaning wiping cloth use first just have enough sizes floor surface general for wet-cleaning time, such as, floor surface in 10 to 30 square metres of regions, such as 15 to 20 square metres further, this structure is proved to be favourable.After the floor terminating wet-cleaning size like this, dry cleaning wiping cloth preferably gets involved further without the need to user and is just eliminated, and this informs user further by optics and/or acoustic signal.

With cleaning wiping cloth previous designs unlike, this cleaning wiping cloth also can be made up of polyurethane foam, and it preferably has detersive active further.Therefore, such as in polyurethane foam, surfactant and friction piece is added.By the rubbing action of the friction piece in foam, constantly remove in cleaning course and carry the foam of foul, and in cleaning process, optionally also to be aspirated by cleaner suction nozzle after cleaning.

Finally, the present invention relates to a kind of method of wet-cleaning floor.

For wet-cleaning floor, usually first need to carry out suction process or cleaning process, to siphon away coarse dirty particles or analog to floor.Just carry out wet-cleaning in the usual manner afterwards.

In order to simplify this process, arranging one by the present invention and remaining on cleaning wiping cloth on the suction nozzle of dust catcher, wherein, realize suction by means of one or more unimpeded suction channel further simultaneously.This suction is preferably carried out at the fringe region of suction nozzle, further such as in front surface region, that is, the common direction of motion of suction nozzle is positioned at the region before suction nozzle.Correspondingly first aspirate bulky grain or analog by unimpeded suction channel, the cleaning wiping cloth afterwards by being arranged on suction nozzle bottom side directly carries out wet-cleaning.

Regulation in this method a kind of favourable further develops, cleanly realizes by means of one wet-cleaning wiping cloth, and the moisture on floor loads outside aspirates.In preferably arranging, the moisture on floor is carried in the contoured surface inside strutted by the suction nozzle of dust catcher to carry out, and is pumped in outside, but is the contoured surface of directly and then suction nozzle.Correspondingly, treat wiped area, especially wet treats that wiped area is sucked all the time in advance, and this is at least on the preferred operative orientation of suction nozzle.At this, unimpeded suction channel is not only arranged on the common front surface region of suction nozzle, but is also arranged on multiple sides of suction nozzle, and even all sides are all furnished with unimpeded suction channel.

Also be proved to be advantageously, the negative pressure when cancelling the supporting of suction nozzle on floor for cleaning wiping cloth-maintenance strengthens.Therefore, ensure in the process that dust catcher lifts, the moistening cleaning wiping cloth also thus becoming weight can also continue to be fixed on suction nozzle.Preferably only suction nozzle lift and thus make cleaning wiping cloth and the floor that will nurse have a spacing time, just need to strengthen negative pressure, this negative pressure strengthen in preferred design by floor wet the suction cross section loading outside closedown or reduce realization.The supporting of suction nozzle on floor detects preferably by a button or analog further.One represents that suction nozzle lacks the push button signalling of supporting by mechanical couplings, but also causes required negative pressure to be strengthened by controller for electric consumption alternatively.

Improving thus further of the cleaning effect of suction nozzle, that is, the common moving direction of relative suction nozzle arranges a floor pump orifice in cleaning wiping cloth front and back, wherein, according to travel direction deexcitation one suction entrance, and activates another suction entrance.Therefore, preferably activate the suction entrance before travel direction further all the time, and be closed in same travel direction suction entrance below.Correspondingly, whole suction force always concentrates on front suction.

Cleaning wiping cloth is removed after cleaning course terminates from cleaner suction nozzle or from the structural member of the cleaner suction nozzle arranged if desired.This can in its simplest form, namely complete with hand.The one design being proved to be especially favourable that views from a sanitation point is that cleaning wiping cloth is inhaled into realize removing after wet-cleaning terminates, and this is realized by the device carrying cleaning wiping cloth in wet cleaning process.In preferred design, this pumping power increasing dust catcher particularly by the short time realizes, and for this reason, such as, can have a corresponding button.For this reason, keep that the suction nozzle of cleaning wiping cloth is corresponding has one towards the sucker of cleaning wiping cloth.When usually running, that is when normally aspirating with the pumping power of standard, cleaning wiping cloth is remained on cleaner suction nozzle by the negative pressure of appropriateness effect.

Detailed description of the invention

First explain that oolemma has one for the treatment of the dust catcher 1 with cleaner suction nozzle 2 on floor 3 with reference to Fig. 1.Described suction nozzle is a kind of carpet surface suction nozzle in an illustrated embodiment.But, the feature that next this suction nozzle 2 illustrates and this suction nozzle 2 further illustrated also can be considered to be applied on the suction nozzle 2 for the treatment of hard floor with the combination of cleaning wiping cloth 4, wherein, suction nozzle 2 such as can be equipped with tiltable mane strip, for optionally processing hard floor and carpet surface.

The nozzle body 6 that nozzle head 5 is connected with dust catcher 1 forms with one primarily of the nozzle head 5 that is placed on floor 3 by suction nozzle 2, wherein, nozzle body 6 is designed with a connecting tubes 7, for being fluidly connected to by suction nozzle 2, being electrically connected to dust catcher 1 if desired.Suction channel, from connecting tubes 7s, extends past nozzle body 6, and this suction channel imports suction inlet 8 in nozzle head 5.

Connecting tubes is so arranged on the upper-side area of the end of nozzle body 6, that is, connecting tubes 7 can at swing hinge place around the axis revolution transverse to the usual moving direction r of suction nozzle 2.In addition, this gyroaxis arranges roller 9, nozzle body 6 is supported on floor 3 by this roller one end.

From the independent view in Fig. 2, in the bottom side of suction nozzle 2 shaping one cut off bottom suction nozzle 10 recessed channel 11, its passage shape ground leads to suction inlet 8, and flows with suction inlet and be connected aptly.In shown form of implementation, be provided with four this recessed channel 11, it is configured in suction nozzle side in couples, and extends with 12 one-tenth, the suction nozzle front miter angle transverse to moving direction r.Recessed channel 11 is unlimited in suction nozzle front 12.Correspondingly, in the illustrated embodiment in which, suction nozzle front 12 place is provided with the sucker 13 of four incision-like.

For process ground, especially carpet surface is processed, be opened towards floor place to be treated is same with suction inlet 8 recessed channel 11 be communicated with that flows, it has a width recorded transverse to recessed channel 11 longitudinal extent, and this width is about as much as 1/1 to six/3rd of recessed channel 11 development length in illustrated form of implementation.

For suction nozzle 2 and cleaning wiping cloth 4 being combinationally used, the structural member 14 that finally supports cleaning wiping cloth 4 is set.At this, it is an insert preferably manufactured in plastics Shooting Technique.

Insert or structural member 14 match with the suction process portion section designing bottom suction nozzle 10, namely match with the geometry obtained by recessed channel 11 and suction inlet 8.Therefore, each recessed channel 11 is configured with the lattice-shaped portion section 15 of structural member 14, and portion's section 15 of this lattice-shaped is correspondingly arranged to cover recessed channel 11.The hole 16 that multiple area reduces is created on opposite, recessed channel hole by the structure of lattice-shaped.

In the region of suction inlet 8, be designed to disc-shaped closed by the structural member 14 in the form of implementation of Fig. 3.

In addition, structural member 14 is configured to, after structural member inserts recessed channel 11 or suction inlet 8, obtain the surface almost equal with adjacent suction nozzle base portion section.

Insert is fixedly clamped in recessed channel 11 or suction inlet 8 or kayser is fixed.

Figure 4 illustrates a kind of alternative structure of structural member 14 or insert.At this, it is not aforesaid lattice structure, but the tabular insert that such as manufactures in plastics Shooting Technique, this insert matches with the geometry limited by recessed channel 11 and suction inlet 8.Attaching troops to a unit in the plate-like portion section 17 of recessed channel 11, remain with the hole 18 of incision-like, for being connected with the circulation of recessed channel 11.

In this form of implementation, the latch portion 19 of plate-like is also equipped with the hole 20 of incision-like, and this hole is towards common moving direction r, and the extension orientation matchingly of the hole 18 of attaching troops to a unit in portion's section 17 of recessed channel and recessed channel 11.

Have nothing to do with the structure of structural member 14 or insert, structural member 14 to insert bottom suction nozzle 10 or recessed channel 11 and suction inlet 8 time, the SS 13 on front side of suction nozzle stays open.

Shown in Fig. 8, the cleaning wiping cloth 4 of the configurable match profiles of suction nozzle 2.Conform to the elementary contour of suction nozzle 2, cleaning wiping cloth 4 also have one roughly in trapezoidal, with the elementary contour of obvious chamfering angular zone.

Cleaning wiping cloth 4 is multilayers, is designed specifically to two-layer, and has effective cleaning layer 21 that form is non-woven fabrics and extend past the sealant 22 on whole surface equally.Sealant is a film, such as plastic sheeting in shown form of implementation.

Cleaning wiping cloth 4 is so configured on suction nozzle 2, makes sealant 22 between effective cleaning layer 21 and the structural member 14 inserted.Fixing on suction nozzle 2 of cleaning wiping cloth 4 realizes by means of only negative pressure, and this negative pressure is formed in the region of recessed channel 11 and suction inlet 8 when dust catcher 1 runs.The structural member 14 inserted is for cleaning wiping cloth 4 provides the supporting of a plane while supporting self, and therefore, cleaning wiping cloth 4 can not be sucked the region of recessed channel 11 or the region of suction inlet 8 by local.

Sealant 22 constructs airtightly, this further improves the adsorption effect that negative pressure causes.In addition, sealant 22 also can construct on waterproof ground, thus prevents from being picked up by cleaning wiping cloth 4 being positioned at moisture on floor 3.In addition, in this kind of design, cleaning wiping cloth 4 itself also can as wet rubbing wiping cloth (rags), such as, further with the cleaning agent be contained in effective cleaning layer 21.

The configuration of cleaning wiping cloth 4 on suction nozzle 2 can realize in its simplest form, that is, be put in cleaning wiping cloth 4 by suction nozzle 2, and then connects dust catcher 1.Thereby is achieved a simple and operation for health.Removing of cleaning wiping cloth 4 also can be carried out in a straightforward manner, as long as by closing dust catcher 1, the corresponding decline of the negative pressure in suction nozzle 2, thus the cleaning wiping cloth 4 remained on suction nozzle is dropped.

By the sealant 22 of cleaning wiping cloth 4 and the air impermeability of associated cleaning wiping cloth 4, the suction force of the SS 13 opened wide at suction nozzle front 12 place is improved.Before cleaning wiping cloth 4 arrives this region, coarse foul can be picked up in wiping process by this SS 13.Correspondingly, region before suction nozzle 2 is positioned on usual moving direction and on corresponding wiping direction r usually by aspirating as wiping is prepared.This does not correspondingly need respectively to the suction that expends surface to be wiped or sweep.These operations complete by means of suction nozzle 2 that is advised, that be equipped with cleaning wiping cloth 4 simultaneously.

Cleaner suction nozzle 2, especially nozzle head 5 can be designed as pre-configured suction nozzle unit, only for a kind of floor type of suction process, pre-configuredly alternatively further process different floor type for selecting, such as handled by foot-propelled and switch between hard floor process and carpet surface process, wherein, lift in the handover or fall curtain device, as mane strip and/or sealing lip.

As shown in FIG. 10 and 11, there is such possibility in another kind optionally designs, that is, cleaner suction nozzle or nozzle head 5 are equipped with a top cover 23 according to the configuration selected.What illustrate is top cover 23 for the treatment of felt side respectively.Top cover 23 grafting is fixed on the bottom side of nozzle head 5, wherein, is designed with the SS 13 of suction inlet 8, recessed channel 11 and front side further in top cover 23 especially.

Shown in Figure 10, top cover 23 is configured with the described structural member 14 as single parts, is pluggable configuration further, and for this reason, structural member 14 has block tongue 24 in shown form of implementation, this block tongue configuration to during top cover 23 with corresponding draw-in groove acting in conjunction.Correspondingly, structural member 14 is optionally attached troops to a unit in top cover 23, that is when wishing wet processed floor by means of the cleaning wiping cloth 4 that can configure in addition.

As shown in figure 11, further alternative, top cover 23 can simultaneously unremovably supporting structure 14, and now structural member 14 and top cover 23 form one for top cover that is nozzle head 5, common, one.Correspondingly, so the top cover 23 of structure is only applicable to Floor wiper process in preferred design after configuration cleaning wiping cloth 4.

Figure 12 to 14 shows another several form of implementation, wherein, is provided with an intermediate layer 25 between structural member 14 and cleaning wiping cloth 4.In the form of implementation shown in Figure 12, intermediate layer 25 is be made up of silicones 26 towards the total surface of cleaning wiping cloth 4.At this, silicones 26 is coated in structural member 14 towards on the surface of cleaning wiping cloth 4 comprehensively, the contiguous lattice-shaped portion section 15 covering recessed channel 11 and suction inlet 8 in described surface.As shown in figure 12, optionally intermediate layer 25 forms the lattice-shaped structure of silicones caterpillar band type in the both sides of portion's section 15 of lattice-shaped.This design improves the frictional force between structural member 14 and cleaning wiping cloth 4, is conducive to cleaning wiping cloth 4 and is adsorbed on better on structural member 14.This makes cleaning wiping cloth 4 be fixed on structural member 14 better, especially in the processing procedure of floor further.At this, cleaning wiping cloth 4 reliably remains on the position of hope.

For balance floor unevenness, in another kind of form of implementation, intermediate layer 25 is set to resilient, further as depicted by fig. 13 by arranging a froth bed 27.This froth bed 27 is not preferably removably fixed on structural member 14, and this is covered structure part 14 further preferably comprehensively, and wherein, for fixing cleaning wiping cloth 4 further, froth bed 27 loads ventilative setting by negative pressure.Correspondingly, the suction of cleaning wiping cloth 4 is undertaken by froth bed 27 via recessed channel 11.In another optional form of implementation, configuration is also only become ventilative to the partial design of recessed channel 11 by froth bed 27, and is air-locked in the lateral side regions of recessed channel 11.

Due to select intermediate layer 25 is arranged as resilient foam layer 27, even if therefore in wet type-floor processing procedure floor 3 injustice cleaning wiping cloth 4 also can be made at least almost to cover all sidedly on floor 3.

By the form of implementation in Figure 14, also there is such possibility, that is, intermediate layer 25 is formed by the foamed material 28 of embossing.The foamed material 28 of this embossing has a surface constructed towards cleaning wiping cloth 4, and such as form is pyramid texture structure, and this structure can make cleaning wiping cloth adsorb more firm, and further for cleaning wiping cloth 4 provides location auxiliary.

According to foregoing embodiments, the foamed material 28 of embossing is connected with structural member 14, the latter preferably covers further comprehensively, wherein, it is ventilative that foamed material 28 is at least set to local (attach troops to a unit in recessed channel 11), therefore, the suction of cleaning wiping cloth 4 realizes via foamed material 28, to make cleaning wiping cloth be adsorbed on foamed material 28.

The sealant 22 be arranged in cleaning wiping cloth 4 extends past the whole surface of cleaning wiping cloth 4 in preferred design.By the sealant 22 arranged especially airtightly, realize cleaning wiping cloth 4 and be fixed on structural member 14 by suction.As shown in figure 15, in another kind of form of implementation, sealant 22 is chosen as only localized design, and that is forming sealant region 29 further, attaches troops to a unit in structural member 14 for aspirating the air inflow hole of cleaning wiping cloth 4 in this region.Therefore, pressing in the form of implementation shown in Figure 15, the attach troops to a unit recessed channel 11 of 10 or the lattice-shaped portion section 15 of structural member 14 bottom suction nozzle of the sealant region 29 in cleaning wiping cloth 4 designs.Cleaning wiping cloth 4 can be at least ventilative outside sealing layer region 29 construct.

One is arranged on sealing lip 30 before the SS 13 of front side for increasing the negative pressure acted in cleaning wiping cloth 4 in by the another kind of form of implementation of Figure 16, strengthens the absorption of cleaning wiping cloth 4 on structural member 14 thus.Absorption strengthens along with the increasing of suction force.

Sealing lip 30, such as form is rubber lip, and the common moving direction r of cleaner suction nozzle 2 extends before sucker 13, and sealing lip covers suction nozzle front 12 substantially, thus, sucker downwardly floor 3 orientation of front side.Sealing lip 30 from shell side, supporter 31 that side direction is adjacent to sucker 13 obtains the support contrary with usual moving direction r.

Further alternative, sealing lip 30 also can have the perforation of window-like, and thus, sucker 13 is not completely covered.Therefore, only sucker 13 is partially sealed for increasing the negative pressure acted in cleaning wiping cloth 4.

The maintenance of cleaning wiping cloth 4 on structural member 14 is improved further by the standing part 32 of design in cleaning wiping cloth 4.This standing part 32 cleaning wiping cloth 4 be designed to overall flat time exceed necessary cleaning wiping cloth development length and extend, in preferred design, be not correspondingly that wiping acts on floor 3 to be treated effectively in running.To this, more preferably attach troops to a unit in the edge of the cleaning wiping cloth 4 in suction nozzle front 12 and configure a standing part 32, for surrounding the edge of structural member 14 towards suction nozzle front 12.

In Figure 17 and 18, a kind of form of implementation has been shown, wherein, standing part 32 is made up of the hard plastic materials and parts 33 of a tabular.This plastic member as be injection-moulded on the edge of cleaning wiping cloth 4 of attaching troops to a unit, and preferably extend completely across the width of the cleaning wiping cloth 4 recorded transverse to usual moving direction r.Alternatively, the standing part 32 of tabular also can by carrying out corresponding machine-shaping to Wiping material, such as, by compressing and/or using plastic coat.

The standing part 32 of structure like this is equipped is seeing the through hole 34 in incision-like transverse to moving direction r, this through hole configures to the SS 13 allocation position of structural member 14 is attached on front side of suction nozzle in cleaning wiping cloth 4.

The negative pressure (with reference to Figure 18) of the edge that structural member 14 configures when cleaner suction nozzle 2 runs by effect realizes surrounding.At this, the standing part 32 of the cleaning wiping cloth 4 kept is positioned at a plane bent from the plane extended spot of effective cleaning layer 21, therefore, in shown form of implementation in a plane perpendicular to effective cleaning layer 21 orientation, realize at least local by means of standing part 32 and close the SS 13 on front side of suction nozzle.The through hole 34 be arranged in standing part 32 forms the corresponding SS towards floor 3 after this.

Alternatively, standing part 32 can as shown in figure 19, directly be realized by cleaning cloth material.This standing part 32 correspondingly relatively the wiping live part of cleaning wiping cloth 4 do not change, and where necessary correspondingly there is a sealant.According to the pliable and tough design that cleaning wiping cloth 4 is common, the standing part 32 protruding from structural member 14 at edge side is sucked when cleaner suction nozzle 2 runs and overlaps the edge to the structural member 14 configured.

In the drawings, the edge on front side of the suction nozzle of structural member 14 is configured with the standing part 32 of a cleaning wiping cloth 4 respectively.In addition, another standing part 32 can be set, such as, be attached to the Background Region of nozzle head 5 or structural member 14, therefore, by suction and the reversing guarantee position of cleaning wiping cloth 4 on structural member 14 of standing part 32, make it landing not occur.

Cleaning wiping cloth 4, in preferred design, when being configured in structural member 14 or nozzle head 5, is designed to be wet, particularly by cleaning wiping cloth 4 soaking with clean liquid.The simplest form of the latter is exactly water, adds clean effective material if desired in addition, as surfactant.In clean process, cleaning wiping cloth 4 discharges clean liquid constantly, for being coated in floor 3.

As shown in figs 20 and 21, cleaning wiping cloth 4 is alternatively at effective cleaning layer 21, and that is have on the surface of structural member 14 dorsad the layer be made up of miniature capsule 35, clean liquid preserved by described miniature capsule.Cleaner suction nozzle 2 arranges the cleaning wiping cloth 4 of so equipment, and this cleaning wiping cloth is placed on after on floor 3 to be cleaned, miniature capsule 35 breaks under by cleaner suction nozzle 2 and dust catcher 1 acts on if desired negative pressure load, and discharges preserved clean liquid.Afterwards, clean liquid is directly absorbed by now still dry cleaning wiping cloth 4, and continues in the usual manner to repeat release in cleaning course.The configuration achieves cleaning wiping cloth 4 just wetted when starting clean use.

Miniature capsule 35 such as by interception columnar structure, the involucrum be made up of hyperfine plastic sheeting formed.

Figure 22 and 23 shows the another kind of form of implementation of cleaning wiping cloth 4.Cleaning wiping cloth is made up of the paper material of four layers in this case, and described paper material clean liquid infiltrates.Cleaning wiping cloth 4 has enough robustnesses under this moisture state, also stands the cleaner suction nozzle 2 being equipped with cleaning wiping cloth 4 and to move around in wiping process and not damaged.After release is kept at the clean liquid in cleaning wiping cloth 4 completely, cleaning wiping cloth 4 is dried up, and because cleaning wiping cloth 4 is selected to be made up of the paper material of four layers, this structure causes cleaning wiping cloth 4 loose and splits into irregular fritter 36 (referring to Figure 23).Now, the little cloth 36 of these dryings is after wet-cleaning, configuration without the need to changing cleaner suction nozzle 2 further is just sucked by this suction nozzle, these fritters are such as picked up by the SS 13 on front side of suction nozzle, but are also aspirated by the hole 16 of the structural member-part 15 of lattice-shaped when cleaning wiping cloth 4 splits into the cloth 36 of dust size or grain size.

In the design that another substitutes, cleaning wiping cloth 4 is made up of polyurethane foam, and this foam, except detersive active is as except clean liquid, has the friction piece 37 that with the addition of surfactant if desired.This friction piece 37 mixes in foam, and local is exposed in the region of wiping active surface.In the process of wet-cleaning, the dirt collected from floor 3 is received by foam, and wherein, the friction piece 37 that local is exposed removes the foam carrying dirt further gradually in the cleaning course undertaken by the friction on floor 3.The cleaning wiping cloth 4 of structure like this is correspondingly in the processing procedure of floor, when removing due to friction, thickness reduces, little by little be decomposed, wherein, the foam beads removed is with the friction piece decomposed or be directly sucked by the SS 13 on front side of suction nozzle, or be sucked in other operation after wet-cleaning end-of-job in wet cleaning process.

Forming the polyurethane foam of cleaning wiping cloth 4 is that negative pressure to be fixed on bottom structural member 14 or suction nozzle on 10, if desired when deleting structural member 14, is designed to airtight, in addition preferably liquidproof ground design further.

Figure 25 shows in another kind of form of implementation, a kind of optional method for removing the cleaning wiping cloth 4 of making dirty afterwards in clean end.At this, cleaning wiping cloth 4, by the whole suction of cleaner suction nozzle 2, to remove, for this reason, is separated for dust catcher 1 configures one the button 38 designed if desired further, can be realized the air blast power obviously increased in the short time by this button in shown form of implementation.By also acting on the suction air flow of the increase in the cleaning wiping cloth 4 of cleaner suction nozzle 2, cleaning wiping cloth 4 is inhaled into via cleaner suction nozzle 2.

By the form of implementation shown in Figure 22 to 25, user just can realize cleaning wiping cloth-removing without the need to contact, obtains the cleaning scheme of a health thus respectively.The dirt held in cleaning wiping cloth is removed together with cleaning wiping cloth 4 simultaneously.

Figure 26 to 29 shows the another kind of form of implementation of cleaner suction nozzle 2.In this form of implementation, arrive connecting tubes 7 and be divided into Liang Ge suction channel branch with the air exhauster of dust catcher 1 suction channel 39 be connected that circulate, namely a maintenance suction channel branch 40 for negative-pressure adsorption cleaning wiping cloth 4 and one are directly used in the suction suction channel branch 41 of aspirating floor 3.As shown in Figure 29, from flow downstream, the bifurcated 42 in suction channel 39 directly designs after connecting tubes 7 substantially.

Suction suction channel branch 41 sets out from bifurcated 42, extend with above channel branch 40 in maintenance, until suction nozzle front 12, at this, suction suction channel branch 41 forms one and extends past the whole width of nozzle head 5 and downward floor suction areas 43 of opening towards floor 3.This regional structure is suction nozzle shape, has the incision-like entrance transverse to usual moving direction r.

Maintenance suction channel branch 40 only forms one downwards, and that is bottom suction nozzle, 10 fabrics opened keep chamber 44.This fabric keeps chamber 44 to be annular, also as substantially closed by the lid 45 that separates maintenance suction channel branch 40 and suction suction channel branch 41 at lid side (deckenseitig), only leaving one and being retained in SS 46 in bifurcated 42.This SS 46 relatively finally forms the suction channel branch 40 that fabric keeps chamber 44, and suction channel 39 cross section being also relatively connected to upstream further reduces, and therefore, the narrow orifice formed plays Venturi tube-suction nozzle.The passage narrow orifice of formation like this is correspondingly filled with the suction air flow of speed rising, thus makes fabric keep negative pressure in chamber 44 to increase.

Fabric keeps chamber 44 to attach troops to a unit bottom the suction nozzle covered by structural member 14 10.At this, in shown form of implementation, (be equivalent to the design in the first form of implementation) relate to the structural member 14 of a lattice-shaped, this structural member is unremovably fixed on the suction nozzle bottom surface of cleaner suction nozzle 2 further in illustrated form of implementation.Alternatively, removably fixing structural member 14 is also possible.

By several structural member-hole 16, the cleaning wiping cloth 4 being arranged on structural member 14 bottom side is fixed by negative pressure when dust catcher 1 runs, and wherein, cleaning wiping cloth 4 extends past the whole surface of structural member 14.In addition specify, except the bottom suction areas 43 on front side of suction nozzle, structural member 14 and cleaning wiping cloth 4 extend past all remaining suction nozzle bottom surfaces.

When the floor suction areas 43 of front side, coarse particles and granule, in the process of cleaner suction nozzle 1 moving movement on floor 3, were sucked before cleaning wiping cloth 4 contacts with corresponding floor part.In order to prevent after suction air flow is closed also may be due to suction suction channel branch 41 in the dirty particles that causes of unexpected eddy current or dust granule fall into maintenance suction channel branch 40; keep the separating device 47 and the suction channel 39 that pass through a filter shape with suction channel branch 40, separate with suction suction channel branch 41 further.This separating device 47 is a filter course being arranged in bifurcated 42 region in shown form of implementation.

From moving direction r, between floor suction areas 43 and the cleaning wiping cloth region be close on moving direction r, arrange one be designed for the sealing lip 48 be bearing on floor 3.Sealing lip extends past the whole width of bottom suction areas 43 transverse to usual moving direction r, and has a vertical cross-section lengths, and this length allows according to selected moving direction upset sealing lip 48.

Sealing lip 48 avoids cleaning wiping cloth 4 and becomes dry due to the air stream aspirated via floor suction areas 43.In addition, sealing lip 48 when crossing flat barrier, such as, provides a kind of servicing unit when crossing threshold.When cleaner suction nozzle 2 slides mobile on moving direction r, also just say the angle eyes front from user, the free end of sealing lip 48 is positioned on the edge belonging to cleaning wiping cloth 4, thus cleaning wiping cloth 4 such as can not be torn or peel off when crossing threshold.Sealing lip 48 is correspondingly crossed for auxiliary simultaneously.

As shown in figure 30, if be all respectively arranged with floor suction areas 43 on rear side of suction nozzle front 12 and suction nozzle, so each floor suction areas 43,43 ' be configured with a sealing lip 48 or 48 ', wherein, be positioned in the direction of movement above, the sealing lip 48 of floor suction areas 43 that do not affect belonging to it be overlapped on towards the edge of cleaning wiping cloth 4, and be positioned at sealing lip 48 ' below in the direction of movement when with towards correspondingly hermetically enclosed floor suction areas 43 ' (with reference to Figure 31 and 32) rearmounted in the direction of movement when deflection.By the hermetically enclosed floor suction areas be positioned in the direction of movement respectively below, whole suction force is towards the floor suction areas 43 be positioned in the direction of movement respectively above.This makes to receive better on floor 3, to be positioned at dust thing before cleaning wiping cloth 4 or foul.

As shown in figure 30, if arrange respectively in the front side of cleaner suction nozzle 2 and rear side floor suction areas 43 or 43 ', so, they suck to suck to circulate with suction channel branch 50 with suction channel branch 49 and a rear portion by the branch of suction channel 39 and a front portion and are connected.Bifurcated 42 correspondingly has three suction channel branches except suction channel 39.

A kind of form of implementation has been shown in Figure 33 and 34, and the floor contact of cleaner suction nozzle 2 is detected in this form of implementation.Following explanation is aspirated on the floor of front side respectively.During other suction occurred in cleaner suction nozzle 2 Background Region arranged where necessary, be provided with identical device.

For detecting floor contact, on front side of suction nozzle, on common moving direction r, in floor suction areas 43, a button 51 is set above.This button has one for being supported on the tactile disk 52 on floor 3 in floor contact position.One bar extended vertically upward perpendicular to tactile disk 52 53 is through bottom suction nozzle 10.A joint cap 54 bending extending longitudinally is hinged with at the free end of bar 53.

One around bar 53, one end is supported on tactile disk 52 and the compression spring 55 that the other end is supported on 10 bottom sides bottom suction nozzle forces button 51 vertically downward, this spring correspondingly when cleaner suction nozzle 2 is placed on floor 3 due to button 51 being absorbed in and being compressed in vertical direction.At this pickup position, joint cap 54 remains on open position as shown in figure 33.

Lift cleaner suction nozzle 2 along with from floor 3, button 51 or tactile disk 52 lose its support on floor 3.Compression spring 55 is correspondingly loosened by it and makes button 51 relatively 10 relative motions vertically down bottom suction nozzle, bar 53 thus by declining at this makes joint cap 54 configure in the position of floor suction areas 43 by cutting out institute shown in Figure 34, and the revolution of chain of command 56 through device side is moved.

According to previous designs, along with fabric keeps the negative pressure in chamber 44 to increase, be automatically turned off by lifting cleaner suction nozzle 2 floor suction areas from floor 3.Therefore, cleaner suction nozzle 2 is corresponding lift time, even if one is wetting and therefore become the bottom side that heavy cleaning wiping cloth 4 also reliably can be fixed on suction nozzle.

All disclosed features are all emphasis of the present invention.Therefore, have also been introduced the full content of affiliated/appended priority document (copy of earlier application file) in the present disclosure of the invention, be also for this purpose, the feature by these files is received in claims of the application.
