Description

Cleaning equipment for clean surface

Technical field

The present invention relates to the cleaning equipment for clean surface.The invention further relates to the mouth of pipe for such cleaning equipment Device.

Background technology

Nowadays hard floor surface cleaner is completed by wiping ground followed by mop to ground progress vacuum cleaning first. Vacuum cleaning removes coarse dirt, and mop wipe is wiped away except spot.Particularly professional cleaning section is positioned at from known in the art The many of door claims the utensil that integral vacuum dust suction and mop are wiped.Utensil for professional cleaning department generally specializes in big face Long-pending and completely flat ground.They go water removal and dirt dependent on scrub-brush and suction from ground.Home appliances is usual Use scrub-brush and the combination for scraping the mouth of pipe.Similar to the utensil for professional cleaning department, these products using brush come from Ground removes spot and picks up dirt from ground using scraping with reference to under-voltage.

Generally by the flexible rubber lip for the bottom for being attached to cleaning equipment realizes the scraper element, and described scrape Element only slides to promote or clean dirt particle and liquid through or out table to be cleaned on surface to be cleaned Face.The under-voltage dirt particle and liquid for being used to suck collection generally generated by vacuum collectors.

Know the scraping device for vacuum cleaning system from such as EP0576174A1.Know from such as US7665172B1 Road uses above-mentioned brush and the sweeper of the combination scraped.Wherein described electric floor sweeper includes sufficient component, this sufficient group Part has the main agitator of motor driving and is coupled to a pair of edge agitators of wheel, so that the manual of the sweeper pushes away Enter to rotate the wheel and so as to rotate the edge agitator.But the sweeper does not include vacuum source and therefore can not be from The ground water absorbing to be cleaned.Performance in terms of dry ground is therefore at a fairly low.

From known to US4864682A from prior art and also using rotating brush and another vacuum of the combination scraped Cleaner.The vacuum cleaner includes self-adjusting sweeper band component, and self-adjusting sweeper band component, which is directed to, uses the vacuum The type of the floor surface of cleaner is automatically adjusted.Component used herein needs high suction to obtain the cleaning knot of satisfaction Really.The brush used in the vacuum cleaner is to stir agitator (and the quilt of ground such as carpet with hard bristle It is expressed as adjuster).These hard hairs show quite good scrubbing effect, and this allows specially to go decontamination using brush Stain.But, the performance in terms of dry ground is at a fairly low, because the agitator can not draw liquid from ground.

From vacuum cleaner known in the art and mop integration apparatus usually using such a brush element, the brush Element is actively sprayed water or cleaning agent to improve the removal of spot.The equipment is usually used to have configuration the one of brush Double scraper elements of two scrapings of side, as exemplarily shown in accompanying drawing 11.Additional vacuum source is filled in double scrape Suction is generated in passage between putting, to remove the cleaning water from ground again.

But in order to remove the cleaning water actively sprayed from ground again, these equipment are had always a demand in side forward To middle movement, the direction of equipment movement is seen, wherein brush is located at before this pair of scratch device in the direction.It is opposite to Rear will drench ground to the mobile equipment, because can not remove the cleaning for utilizing brush distribution from scraping in this is acted backward Use water.

In order to the forward and backward of the equipment traveling in obtain good cleaning result, it is known that cleaning equipment therefore Possess two scraping mouths of pipe in the both sides of brush.The device is exemplarily shown in accompanying drawing 12.Although on the both sides of brush This pair of scratch device show good cleaning result, but the mouth of pipe of these equipment becomes quite big.Again leading to be discontented with The limited ability to work of meaning.The large volume mouth of pipe is due to him particularly in the home appliances for usually requiring to clean narrow corners The limited degree of freedom of motion be unfavorable and be using uncomfortable.

In addition, there are many other shortcomings using double scratch devices as shown in accompanying drawing 11 and 12.Due at this The scraping of the mobile period of equipment and the continuous contact on ground, this pair, which scrapes, to generate high scraping in face over the ground.Particularly work as When on each side of brush using double scratch devices, this improves the risk for causing to cause on the ground scraping.In addition, this pair Scraping includes the shortcoming that they can not open for the coarse dirt of such as hair or peanut, because coarse dirt is generally involved in scraping In or be scratched and push open, and therefore it can not enter suction intake.In addition, this pair scrapes the mouth of pipe and is difficult to clean simultaneously And without self-cleaning ability.

In order to overcome these shortcomings, other equipment known in the art uses parallel to each other two brushes separated (being schematically shown in accompanying drawing 13).Such cleaning equipment is exemplarily known from US1694937.The file is disclosed Wiping ground machine, it can be tidied up by two cylindrical ground brushes that are parallel and being immediately arranged together from ground (pick up) dirt.Rotate at high speed, one is run and another operation counterclockwise these brushes clockwise.So, it is adjacent Periphery with sufficiently high speed advance to together, with using substantial flat jet form relatively large power vertically upward Project dirt.Sweeper or scraping are also applied in addition to brush, so as to dry ground.Due to the brushes of two separation and additional Scraping, also become quite big according to the mouth of pipe of the technical scheme, will again lead to the unsatisfied degree of freedom of motion of customer.

The content of the invention

It is an object of the invention to provide a kind of improved cleaning equipment, it shows improved cleaning compared with prior art Performance is while the mouth of pipe with small size is to ensure the high degree of freedom of motion.

The purpose is realized by a kind of cleaning equipment for clean surface, the equipment includes：Nozzle device, it is wrapped Include：

I) on brush axle rotatable brush, the brush is equipped with flexible brush element, and the flexible brush element has point Point, during the rotation of the brush when the brush element contacts surface to be cleaned, the tip portion is used to contact surface to be cleaned And dirt particle and liquid are tidied up from the surface during the cycle of tidying up, the line mass density of the plurality of brush element is at least In every 10 km in less than 150 grams of the point office；And

Ii) single scraper element, for promoting or cleaning dirt particle and liquid warp in the mobile period of the cleaning equipment Cross or leave the surface to be cleaned, the scraper element separated with the brush and substantially along with substantial parallel vertical of brush axle Extend to direction, wherein suction areas is defined in the nozzle device between the scraper element and the brush,

For drive the brush rotate drive device, wherein the drive device be adapted to be the tip portion realize from Heart acceleration, wherein, specifically discharged during the rotation of the brush in the dirt when the brush element is not in contact with the surface During cycle, the centrifugal acceleration is at least 3000m/s², and

Vacuum collectors, it is under-voltage to suck dirt particle and liquid for being generated in the suction areas.

According to the second aspect of the invention, in addition by the corresponding mouth of pipe for being used in foregoing cleaning equipment Device realizes above-mentioned purpose.

The preferred embodiment of the present invention is defined in the dependent claims, it should be appreciated that mouth of pipe dress claimed Put scraper have it is similar to the preferred embodiment defined in cleaning equipment claimed and dependent claims and/ Or identical preferred embodiment.

Idea behind the present invention is by the point during the rotation of the tip portion of brush element in brush element The density parameter and the specific combination for the centrifugal acceleration realized of office selection brush element, can by only apply one it is single Scraper element is scraped and pair shortcoming of brush clean technologies schemes to overcome above-mentioned pair.With from cleaning equipment known in the art Difference, the nozzle device of current cleaning equipment only includes single scraper element and preferably only includes a main brush.Due to Only there is a brush and a scraper element, therefore the mouth of pipe becomes smaller and show improved operability.

Therefore the cleaning equipment also allows to clean narrow surfaces in an efficient way.Because selected parameter is Flexible brush The upper limit of the line mass density of element is that the lower limit of the centrifugal acceleration of the tip portion of 150 grams of every 10 kms and brush element is 3000m/s²(realizing the acceleration by drive device), can realize outstanding cleaning result, wherein actually disposable remove The particle on surface to be cleaned and dry surface to be cleaned.

It is such as given in this article that there is flexibility compared with being only used for the brush of greasiness removal according to used in prior art The soft brush of brush element also has the ability that water is tidied up from ground.Therefore, it is no longer necessary to the second scraper element.Use brush element Above-mentioned parameter on line mass density and centrifugal acceleration, which also show, causes very good greasiness removal characteristic.Due to quilt Preferably as the flexible microfibre fine hair of brush element, when brush element/microfibre fine hair contact ground during the rotation of the brush When, dirt particle and liquid can be tidied up from the ground.With brush also come the ability of tidying up liquid be by capillary and/or other Caused by adhesion, wherein the adhesion is due to the selected line mass density of the brush element and for driving brush to be sent out Raw high speed.Because microfibre fine hair is very thin, so brush is also what is opened for coarse dirt.

Brush rotate during, the brush element using they tip portion contact ground and the tip portion with Ground contact tidy up the cycle during tidy up dirt particle and liquid from ground.Brush element be located at mouth of pipe outer cover inside and with In surface contactless dirt deenergized period, the centrifugal acceleration of the tip portion of brush element is uprised so that what is produced is presented in The centrifugal force of dirt and liquid particles in the microfibre fine hair becomes stronger than by it and to oppress dirt and liquid from brush element The adhesion of grain.Therefore dirt when contactless with surface among mouth of pipe outer cover during rotation of the brush element at them is released Put automatic release dirt and liquid particles in the cycle.In addition to centrifugal force as described above, other acceleration forces can occur, Especially because acceleration force caused by the deformation of the flexible brush element.The deformation can for example occur when the flexible brush element When contacting ground during rotating or running into liquid or dirt particle.

Lost during rotation of the brush element at them with ground when contacting, it is occurring in the point office of brush element plus Speed causes to discharge dirt particle and liquid droplet automatically from brush.Due to whole dirts can not be directly sucked in by vacuum collectors Particle and liquid droplet, so also liquid will splash down and returns on the surface in such a region a small amount of dirt, wherein brush element Lose and contact with ground in this region.But the influence for splashing the surface again, the wherein scraper element are overcome by scraper element Weight splashing liquid body and dirt are collected by being used as a kind of sweeper, so that because the under-voltage of application can then suck remaining liquid Body and dirt.Therefore scraping again ensures that the remaining liq and dirt that are not sucked by vacuum collectors without departing from suction areas.Its Therefore the dirt and the suction areas of liquid closed on the side of mouth of pipe outer cover.Because selected brush combination is (except dirt Outside can also tidy up liquid) using single scraper element promote or clean dirt particle and liquid it is to be cleaned through or out this Surface, therefore it can almost clear up the dirt particle and liquid of optical surface.This causes improved sanitary characteristics while subtracting The size of the small mouth of pipe.

By the way that the quantity of scraping is reduced into only single scraper element, it can not only reduce the size of outer cover to cause the mouth of pipe Volume is smaller but also can significantly reduce may the scraping to ground caused by scraping.In addition, single scraper element To be easier cleaning much.

Separated due to being scraped in given device with brush and substantially along longitudinal direction preferably parallel with brush axle Direction extends, so brush and single scraping together form suction areas.The suction areas is under-voltage region, this is under-voltage region For sucking dirt and liquid particles by scraper element or brush collection.Preferably by being connected to the suction district in any way The vacuum collectors generation in domain is described under-voltage.

Brush is arranged preferably in one of the outer cover of the mouth of pipe, and by scraper element configure opposite side in the outer cover with The brush is parallel, so that when the desired moving direction viewing in the equipment, brush seems after each other with scraper element Face.Scrape and brush be configured in the bottom side of mouth of pipe outer cover (its equipment during use face surface to be cleaned) on and Protruded at least in part from the bottom side from the mouth of pipe outer cover.When the mobile equipment, scraper element is slided over a surface to be cleaned It is dynamic and so as to promote or clean dirt particle and liquid through or out ground, and the brush is simultaneously during the rotation of brush Dirt and liquid particles are tidied up from surface.So, suction intake is created between the brush and scraper element, in cleaning equipment Suction intake faces surface to be cleaned during use.The suction intake is opened towards above-mentioned under-voltage suction areas is created.

By application, this is under-voltage, sucks and siphons away the dirt and liquid particles by scraping and brush is tidied up from ground.Should Therefore brush and scraper element is always maintained at totally, from without the risk in surface distribution dirt to be cleaned.In other words, this Cause a kind of self-cleaning brush and scraping.

Brush element can be made from a plastic material, and wherein polymer and nylon are suitable examples.In any case, it is many The line mass density of individual brush element is at least in every 10 km in less than 150 grams of the point office.This is ensured at least in the point The office brush element is flexible enough to undergo curvature effect and can tidy up dirt particle and liquid droplet from surface to be cleaned.

In addition the degree of the abrasion of the brush element seems to receive in the line mass density range.It should be noted that carrying To the line mass density be unit be gram every 10 km line mass density be represented as Dtex values again.

The Dtex values that are proved in above range of experiment that the applicant is carried out seem be technically it is feasible and Good cleaning result can be obtained using it.But the lower Dtex values upper limit can be had (such as by application by having shown that Dtex values 125,50,20 or even 5 (grams km)) brush element further improve cleaning result.

Utilize value below, it is ensured that cleaning result is outstanding, water tidy up most preferably, wear and tear newest and over a surface to be cleaned Power consumption and be thermally generated it is sufficiently low.Also note that, at least in dirt contactless with surface during rotation of the brush element in brush In thing deenergized period, no matter what the acceleration dominant in point office be, minimum value 3000m/s²Also by this hair The support of the experimental result of executed in bright environment.These experiments have shown and utilized according to the clean-up performance of the equipment of the present invention The increase of the angular speed of brush is improved, it means that increase the acceleration in the point office of brush element during rotation Degree.

According to the embodiment of the present invention, the drive device is adapted to be realizes at least 7000m/s in the point office² Centrifugal acceleration and more preferably 12000m/s²Centrifugal acceleration.When the drive device is adapted to be in above range It is middle realize brush element centrifugal acceleration when, the centrifugal acceleration and surface to be cleaned it is contactless during, adhere to the brush The liquid droplet of element is discharged possible as droplet mist.

The combination of acceleration at the line mass density of brush element and the tip of brush element is to produce rotatable brush most The combination of good clean-up performance, wherein, the whole dirt particles run into by brush are specifically tidied up by brush element and liquid is splashed down And discharged at the position inside mouth of pipe outer cover.Certainly, when start cleaning when particle and liquid effectively tidy up be it is favourable, Wherein, while realizing that dirt is removed and drying process.In view of the fact that cause dirt and/or liquid on surface again is avoided, It is favourable effectively to thereafter let out process.Above-mentioned scraper element is combined using according to the brush of the present invention and real by drive device Existing operating parameter, by particle capture into droplet so that particle is actually bigger, and this allows simpler filtering.

Do not found in the knowledge based on prior art on line mass density and real in the point office of brush element The combination of the above-mentioned parameter of existing centrifugal acceleration.Prior art is even indifferent to only one and is used for clean surface and goes back The automatic best-of-breed functionality of the rotatable brush of dirt and liquid can be risen, and therefore, it is possible to the scraping member required for reducing The quantity of part, but still realize the possibility of identical or even improved sanitary characteristics.

When providing at least one rotatable brush and when being operated as described herein, it ensures can be to be cleaned Surface effectively removes liquid, and be also for dirt particle it is identical, can by brush brush element capture and/or with Liquid takes away dirt particle together.One in mouth of pipe outer cover is by rotatable brush brushing surface and first by scraping in opposite side Part continuous contact surface and so as to cleaning the surface to perform cleaning process, the cleaning process is particularly suitable for applications in hard table On face.The example of crust is hardstand, window, wall, desktop, the plate face of hard material, side wall etc..

According to the preferred embodiment of the present invention, by vacuum collectors generate it is under-voltage in 3 to 70mbar scope, it is excellent Selection of land is in 4 to 50mbar scope, and most preferably in 5 to 30mbar scope.The vacuum cleaner of prior art Need using higher under-voltage to reach acceptable cleaning result.But, due to the above-mentioned characteristic of brush, in above-mentioned pressure Very good cleaning result is had been carried out in scope.Therefore, also using smaller vacuum collectors.Which increase vavuum pump The free degree in selection.

According to another preferred embodiment of the present invention, the longitudinal direction of brush axle and/or scraper element is configured to horizontal stroke Wear the intention moving direction for being preferably perpendicular to cleaning equipment.In the mobile period of the equipment, brush and scrape to meet To the dirt and liquid particles along their complete longitudinal side.By the way that brush axle and scraper element are configured to put down each other OK, establish brush to cooperate with the perfection of scraper element, to tidy up dirt and liquid particles from ground.In scraper element and brush Under-voltage suction areas is defined between son, it is also substantially extended parallel to brush axle.

In another preferred embodiment of the present invention, the scraper element includes being used to the scraper element being switched to Closing position and the switching device that the scraper element is switched to open position, wherein the scraper element in the closing position It is adapted to be when mobile cleaning equipment in forward direction over a surface to be cleaned, promotes and clean dirt particle and liquid Body passes through and leaves surface to be cleaned, wherein scraping in the moving direction of the cleaning equipment in the forward direction Element is located at behind the brush, and wherein in the open position when on the surface to be cleaned after it is mobile into direction should During cleaning equipment, dirt particle and liquid from the ground can pass through opening between the scraper element and the surface to be cleaned Mouth enters suction areas, wherein into direction, the scraper element is located at this in the moving direction of the cleaning equipment after this Before brush.

The ability that the scraper element is switched to closing position from open position is allowed according to the moving direction of cleaning equipment Good cleaning result in the forward and backward stroke of the mouth of pipe.The opening device is in order to close before brush when scraping Dirt is allowed to enter during dirt and liquid on ground.And in closing position, when brush before scraping on the ground Dirt or liquid when, scrape and be closed into the gap on ground, or, in other words, clean or slide on the ground.

In order to ensure the switch mode, the scraper element is preferably realized by flexible rubber lip, the rubber lip is adapted to be On the longitudinal direction of the rubber lip it is flexible according to the moving direction of the cleaning equipment.The rubber lip preferably include to A few column cap, the column cap configures the lower end in the rubber lip, and the wherein rubber lip is applied to contact surface to be cleaned.Institute At least one column cap is stated to be adapted to be when on a surface in rear mobile cleaning equipment into direction, at least in part from table The rubber lip is risen in face, wherein into direction, the rubber lip is located at the brush in the moving direction of the cleaning equipment after this Before son.Because the rubber lip is in rear rise into traveling of the mouth of pipe, wherein scraper element close ground before brush On dirt, coarse dirt can also it is rear into stroke by the opening that is created between the scraper element and surface to be cleaned Into the mouth of pipe.When mobile cleaning equipment in opposite forward direction on a surface, the column cap and ground are contactless, So that rubber lip from the ground on the ground slidably to tidy up dirt and particle water.

According to another embodiment, the nozzle device includes the outer cover at least partly around the brush, wherein should Scraper element is attached on the outer cover.In the apparatus, the brush is surrounded and at least by the mouth of pipe outer cover at least in part Partly protruded from the bottom side of the mouth of pipe outer cover, wherein the bottom side of the mouth of pipe outer cover in the equipment during use in face for the treatment of Clean surface, so that, the scraper element contacts the surface outside the outer cover during the rotation of the brush.Preferably will The scraper element is attached to the bottom side of the outer cover, to contact surface to be cleaned when moving the mouth of pipe on said surface. In the equipment during use, should defined in the space between the brush, the outer cover, the scraper element and surface to be cleaned With above-mentioned under-voltage suction areas, wherein configuring the suction intake between the scraper element and the brush.

According to another preferred embodiment, the cleaning equipment includes positioner, and the positioner is used to treat from this Position the brush axle at the distance of clean surface, wherein the distance is less than the radius of the brush, using the brush element of full extension come The retraction of the brush part contacted during operation with surface is realized, this is retracted within the scope of 2% to the 12% of the brush diameter In.

As a result, when brush is contacted with surface, brush element is bent.Therefore, once during the rotation of brush brush element and table Face is contacted, the outward appearance of brush element just from outward appearance change is stretched to bending outward appearance, once and brush element during the rotation of brush Lose and contact with surface, the outward appearance of the brush element is just from bending outward appearance change to stretching, extension outward appearance.

The actual range of brush retraction is 2% to the 12% of the brush diameter of the full extension situation on brush element. In actual conditions, it can for example be shone by performing suitable measurement by using high speed of the operation in the speed of the brush Camera or stroboscope perform suitable measurement to determine the diameter of above-mentioned brush.

The speed when deformation of brush element or more precisely deformation occur is also by the line mass density of brush element Influence.In addition, the power required for the line mass Effects of Density rotation brush of brush element.When the line mass density of brush element is relative It is flexible relatively high when low, and the power for causing brush element to bend when brush element is contacted with surface to be cleaned is relatively low.This is also Mean that the friction horsepower generated between brush element and the surface is low, thus prevent the surface heat and with the surface phase The breakage of pass.Other favorable influences of the relatively low line mass density of brush element are relatively high wear-resistant, by sharp object The chance that body etc. is damaged is relatively small, and allows tight in the way of contact is also maintained even if the actual out-of-flatness run into surface Paste the ability on surface.

When brush element is contacted with dirt particle or liquid or in the case of retraction of the brush on surface is provided with, brush Element is bent.Contacted once the brush element for having adhered to dirt particle and liquid loses with surface, the brush element is straightened, wherein especially The tip portion of ground brush element spends movement at relatively higher acceleration.As a result, centrifugation of the increase in the point office of brush element adds Speed.Therefore, and because the centrifugal force according to embodiment of above is more than adhesion, the liquid that will be adhered on brush element Body droplet and dirt particle throw away brush element.By various factors including the deformation mentioned and line mass density still also by brush quilt The speed of driving determines the value of acceleration force.

The factor of playing the part of additional role in the cleaning function of rotatable brush is that brush element ties up density.It is close when tying up When spending sufficiently large, can occur capillary effect between brush element, this enhancing quick removal of liquid from surface to be cleaned.Root According to embodiments of the present invention, the density of tying up of brush element is at least that 30 cluster brush elements are every square centimeter, wherein the brush member per cluster The quantity of part is at least 500.

Brush element configuration cluster is formd into additional capillary channel, so that increase brush tidies up dirt from surface to be cleaned The capillary force of composition granule or liquid droplet.

According to another preferred embodiment, the line mass density of the total main body of brush element is (at least in tip portion On) it is less than 20 grams of every 10 kms.The important advantage of the low Dtex values is that the abrasion of brush element is minimum.In this case, Brush element can be categorized into very soft and flexible, this is opposite with many situations of prior art.

In order to which above-mentioned centrifugal acceleration is realized in the point office in brush element, according to an embodiment of the invention, The drive device realizes the more excellent in 3000 to 15000 rpms of scopes of the brush during being adapted in the operation of the equipment Angular speed of the selection of land in 5000 to 8000 rpms of scopes.The experiment of applicant is it has been shown that when with least 6000 revolutions per minute Optimum cleaning result can be obtained during the angular speed driving brush of clock.

But depend not only on the angle corresponding to brush frequency in centrifugal acceleration desired by the point office of brush element Speed, additionally depends on the radius corresponding to brush diameter.Therefore according to another implementation of the invention, when brush element is in When under the conditions of full extension, brush preferably has in the range of 10 to 100mm and more preferably 20 to 80mm scopes and most It is preferred that the diameter in the range of 35 to 50mm, and wherein, when brush element is in full extension condition, at the length of brush element In 1 to 20mm scope in preferably 8 to 12mm scope.

As described above, the cleaning equipment provided has the ability for realizing fabulous cleaning result.Activity even can be passed through Drench surface to be cleaned to improve these cleaning results in ground.This is particularly advantageous in the case of greasiness removal.Can be with respectively The mode of kind provides the liquid used during the adhesion of enhancing dirt particle and brush element.It can be treated first by appearing in Liquid in clean surface drenches rotatable brush and flexible brush element.One example of the liquid is water or water and soap Mixture.Selectively, can by actively to brush provide cleaning solution body for example by the way that liquid is exuded on brush or In hollow core element of the person by injecting liquid into brush cleaning liquid is provided to brush.

According to an embodiment, thus preferably the cleaning equipment include be used for brush brush axle extend width on Per cm speed per minute less than 6 milliliters provides the device of liquid to brush.Necessity is appeared not to carry with higher speed For liquid, and above-mentioned speed is enough to make liquid to complete the function as the carrying/transmitting device for being used for dirt particle.Therefore, The ability for removing spot from surface to be cleaned can be significantly improved.Using only an advantage of seldom liquid it is that essence can be handled Close surface, or even it is indicated as the surface to liquid such as water sensitive.In addition, giving for accommodating the liquid to be supplied to brush Water receiver size, autonomous (autonomy) time is longer, that is, empties and need to fill up the time of the water receiver again more It is long.

It should be noted that, additionally it is possible to be changed to using splash liquid i.e. will from surface to be cleaned remove liquid come instead of using Liquid that is deliberately selecting and actively supplying.Example is coffee, milk, tea for splashing etc..In view of brush as described above Element can remove liquid from surface to be cleaned and can be under the influence of foregoing centrifugal force from brush element removal The liquid, what this was possible to.By by collected as a kind of sweeper the scraper element of the heavy liquid splashed and dirt come The above-mentioned influence on the surface in the region between splashing brush again and scraping is overcome, so that because the under-voltage of application can suck residue Liquid and dirt.Scrape thereby, it is ensured that the remaining liq and dirt not sucked by vacuum collectors are without departing from suction surface.Cause This closes the suction areas for dirt and liquid on a side of mouth of pipe outer cover.Scraping and the combination of selected brush are therefore Cause extraordinary cleaning and drying effect.

According to another preferred embodiment, the cleaning equipment also includes being used in the side back to the scraper element of brush On face, the device that air stream is generated in the region on surface to be cleaned is contacted during operation of the brush in the equipment.The sky Air-flow mainly has the function of offsetting the air stream produced during the rotation of the brush.Due to the high speed for driving the brush Degree, rough air may be generated in the outside of mouth of pipe outer cover, and rough air may force the dirt particle occurred on a surface The region from the brush element initial contact ground during rotation is blown far with liquid droplet.

In order to avoid the detrimental effect, can apply is used to generate air in the region on brush contacts surface to be cleaned The device of stream, so as to compensate the air stream as caused by brush.It is therefore preferred to by the confrontation air stream of generation it is inwardly directed with Suction effect is generated, the suction effect forces the mouth of pipe that dirt particle and liquid droplet be directly entered before brush or by brush Run into and then tidied up as described above by brush.A possibility for realizing air stream generation is in pipe before brush Small opening is configured between mouth outer cover and brush, wherein the brush element leaves the mouth of pipe outer cover during rotation.So, in the pipe The second suction intake is created before mouthful.

According to another implementation of the invention, the cleaning equipment includes deflector, and deflector is used for from rotation side To apparently before the brush contacts the surface to be cleaned during rotation at a position contact brush.So, by deflecting Device oppresses brush element together, so that the air quilt in the space being consistently present in during the operation of equipment between brush element Push out the space.In region between the deflector and the surface to be cleaned, the brush element will be stretched again and Movement is opened each other, to increase the region between brush element.The unexpected increase in the space between brush element connects first in brush element Generated in the region for touching surface to be cleaned additional under-voltage.This it is additional it is under-voltage generate additional suction effect, by it Air and it is inhaled into brush so as to also dirt and liquid particles.Due to close to being pressed together by surface to be cleaned Air is inhaled into brush at position, thus caused by the rotation and its contact with surface to be cleaned of brush it is above-mentioned not Desired turbulent airflow is effectively compensated.

Deflector prevents water or the droplet of cleaning liquid from falling back on cleaned surface in addition.In optimal cases, The deflector is configured as fully contacting brush so as to ensure above-mentioned functions.In one implementation, deflector can be such as It is directed towards the simple part of mouth of pipe outer cover prominent on the inside of outer cover and so as to contact brush element during the rotation of brush.This is inclined Turning device can be realized or can be real by being attached to the flexible member of the mouth of pipe outer cover by the hard part of mouth of pipe outer cover in itself It is existing and can be at least partly flexible when being contacted with brush element.

According to another preferred embodiment, the brush is to be configured with form spirally in the peripheral of the brush The spiral brush of cluster.The coiled arrangement of the cluster is significantly by the pumping power required for reduction.Generally, in this context, such as It is favourable that cluster is configured to the row with moderate interval by fruit.

Brush 12 is surrounded by mouth of pipe outer cover 28 at least in part.The setting of brush 12 among mouth of pipe outer cover 28 preferably by It is chosen so as to brush 12 to protrude from the bottom example 30 of mouth of pipe outer cover 28 at least in part, in bottom side during use of equipment 100 30 face surface 20 to be cleaned.

Scraper element 32 is also attached to the bottom side 30 of mouth of pipe outer cover 28.Scraper element 32 is configured as setting it Standby 100 surface 20 to be cleaned of contact during use.Scrape 32 and be used as a type of cleaning element, for when mobile clear Dirt particle 22 or liquid 24 are promoted or cleaned during clean equipment 100 through or out surface 20.It is described scrape 32 preferably with Brush 12 is separated and substantially extended parallel to brush axle 14.Mouth of pipe outer cover 28, scraping 32 and brush 12 are together defined and taken out Region 34 is inhaled, suction areas 34 is located among mouth of pipe outer cover 28.It should be noted that the present invention implication in suction areas 34 not only Brush 12 is only represented, the region between 32 and mouth of pipe outer cover 28 is scraped and is also represented by during the rotation of brush 12 in brush element 16 are located at the space between brush element 16 in the time inside mouth of pipe outer cover, and it is represented in scraper element 32 and brush 12 Between the region that defines.Latter region is hereinafter represented as the suction intake 36 in the split shed of suction areas 34 again.

By the vacuum collectors 38 only symbolically shown in the accompanying drawings, generated in suction areas under-voltage to suck The dirt particles 22 or liquid 24 for being run into and being collected by brush 12 and scraping 32.It is described under-voltage preferably 3 according to the present invention Into 70mbar scope, more preferably in 4 to 50mbar scope, and most preferably in 5 to 30mbar scope. It is more at a fairly low compared with application about 70mbar under-voltage conventional vacuum cleaner that this is under-voltage.But it is due to the above-mentioned of brush 12 Characteristic, has been realized in extraordinary cleaning result in above-mentioned pressure limit.Accordingly it is also possible to be assembled using smaller vacuum Device 38.Which increase the free degree of the selection of vavuum pump.

Idea of the invention is that by application on brush element 16 line mass density above-mentioned parameter and by The centrifugal acceleration at the tip portion 18 of brush element 16 is realized in above range, by using single brush 12 and single can be scraped The assembling mouth of pipe 10 of element 32 is wiped to realize extraordinary cleaning result and dirt removal behavior.

With the need for known in the art assembling at least two scrape (each side one of brush) or need dress The nozzle devices of two brushes with rotate counterclockwise on the contrary, in order to reach good cleaning result, provided herein is technical scheme Cause to save very much space-efficient nozzle sizes.Using provided herein is the good sanitary characteristics that can realize of technical scheme it is main according to Rely in brush 12, can not only be from treating because aforesaid operations parameter is opposite with the hard brush in the technical scheme of prior art Clean surface 20 tidies up dirt particle 22 and can tidy up liquid 24 from surface 20 to be cleaned.

Because brush 12 also has the ability for tidying up water 24, the such double scrapings exemplarily shown in figs. 11 and 12 Technical scheme is no longer necessary.This depend on water be not only due to generation it is under-voltage from ground tidied up and by the quilt of brush 12 The fact that risen from land operations.Even if still being stopped by surface in the rear mouth of pipe mobile into stroke as shown in Figure 1 Water 24 and dirt particle 22 on surface 20 (are not used in under-voltage from table in the suction areas 34 at suction intake 36 Water and dirt that face 20 is directly sucked in) brush 12 is being run into after scraping 32 and suction intake 36 and so as to be raised. Such backward stroke represents movement of the nozzle device 10 in the moving direction 40 of intention, wherein in brush 12 in direction 40 Scraper element 32 runs into the dirt particle 22 and liquid 24 appeared on surface 20 before running into dirt particle 22 and liquid 24. The situation is schematically illustrated in Fig. 1.

The feelings for actively sprinkling water in brush 12 and (being normally usually the greasiness removal improved in surface 20 and done so) In condition, the backward stroke will be such that cleaning liquid rests on the surface if brush 12 can not also tidy up the water spilt again. Additional scraping must be used in this case to ensure to go water removal from ground 20.But according to the present invention due to brush 12 Given characteristic, it is unwanted to drive the speed of brush 12 and the combination with scraping 32.

In order to ensure the good cleaning result in (shown in Fig. 1) backward stroke and (shown in Fig. 2) forward direction stroke, Scraper element 32 preferably includes switching device 42, and switching device 42 is used for the moving direction according to the mouth of pipe 20 on surface 20 40,32 will be scraped and be switched to closing position from open position and vice versa.If in (shown in Fig. 2) forward direction stroke The mobile mouth of pipe, wherein being located at from the scraper element 32 of moving direction 400 of cleaning equipment 100 behind brush, scrapes to be in and closes Close in position.In the closing position, scrape 32 and be adapted to be by sliding promotion more or less on surface 20 or cleaning Dirt particle 22 and liquid 24 are through or out surface 20.It is preceding into stroke at this, 32 are scraped consequently as one kind from surface 20 Collect the sweeper for the remaining water for not being raised or being spread across from brush 12 on 20.Then can by suction areas 34 it The under-voltage suction of middle application is by scraping the 32 remaining water collected.

On the other hand, 32 will be scraped when the mobile mouth of pipe 10 in (shown in Fig. 1) backward stroke to be configured in opening Open in position, wherein, 32 are scraped in moving direction 40 and is located at before brush 12, so that surface will be being run into by brush 12 Before dirt particle 22 and liquid 24 on 20 dirt particle 22 or liquid 24 are run into by scraping 32.After this into stroke, Switching device 42 is switched to his open position by scraping 32, wherein, dirt particle and liquid from surface 20 will be by scraping The opening wiped between 32 and surface to be cleaned 20 enters suction areas 34.So, dirt particle 22 and liquid 24 can also taken out Enter suction areas 34 at the position of suction inlet 36 and run into brush 12, tidied up using brush 12 from surface 20.

If can not will scrape 32 is switched to the open position, only very small amount of dirt particle 22 is possible to reach Suction intake 36, and most of dirt and liquid will be scratched and be involved in and be forced through surface 20 and can not enter suction areas 34.This will cause cleaning and the drying effect of difference certainly.

In order to ensure the orientation-dependent switching of scraper element 32, scrape 32 and preferably include flexible rubber lip 46, Flexible rubber lip 46 is adapted to be depending on the moving direction 40 of cleaning equipment 100 Flexible.The explanatory view for the amplification for scraping 32 is shown in figs. 5 and 6.Fig. 5 shows scraping in its closing position Wipe 32 and Fig. 6 shows the scraping 32 in its open position.

Column cap 50 is configured in the lower end of rubber lip 46, is intended to contact surface in the lower end wherein scraping 32 20, column cap 50 is adapted to be when the mobile cleaning equipment on surface 20 in (shown in Fig. 1) backward direction 40 from surface 20 rise rubber lip 46 at least in part, wherein being located at brush 12 in moving direction 40 rubber lip into direction 40 In the view of rear Above.In this case, rubber lip 46 is risen, this is mainly due to the natural friction occurred between surface 20 and column cap 50 Power, the frictional force rubber lip 46 and forces rubber lip 46 to be overturn on column cap 50 as a type of stopper to slow down. Therefore force scraping 32 to be slided on column cap 50, wherein rise rubber lip by column cap, and be open 44 appear in rubber lip 46 with In space between surface 20 (see Fig. 6 a and 6b).

Fig. 3 and 4 shows the second embodiment of nozzle device 10, and Fig. 3 and 4 is shown and (shown in Fig. 1 and 2) the One embodiment, which is compared, can exchange the position for scraping 32 and brush 12 without departing from the scope of the present invention.In this case, Scrape 32 and another side in mouth of pipe outer cover 28 is fitted to be relative to brush axle 14.In this case, when the institute in such as Fig. 3 Scraper element 32 necessarily be in open position certainly during the mobile mouth of pipe 10 in the forward direction stroke shown, wherein, moved in direction 40 The mouth of pipe, 32 are scraped before brush 12 in direction 40 in moving direction 40.Otherwise liquid 24 and dirt particle 22 will Suction areas 34 and corresponding suction intake 36 can not be entered respectively again.

On the other hand, when according to the embodiment in the mobile mouth of pipe into stroke after as shown in Figure 4, scraping 32 must It must be in its closing position, wherein brush 12 is located at before scraping 32 and initially encounters dirt in moving direction 40 Particle 22 and liquid 24.In this case, 32 are scraped again as being slided on surface 20 and collect the residue on surface 20 Dirt particle 22 and liquid 24 sweeper.

By the way that the first embodiment shown in Fig. 1 and 2 is compared with the second embodiment shown in Fig. 3 and 4, to note Anticipate to the characteristic of the other parts of device, i.e. brush and the characteristic of mouth of pipe outer cover 28 and keep identical.The even rotation of brush 12 Direction 26 needs to keep identical, because the direction of rotation 26 of brush 12 needs to be oriented such that brush element 16 in mouth of pipe outer cover 28 Also configure scrape 32 side on enter mouth of pipe outer cover 28.Otherwise, this will not be able to allow brush 12 and scraper element 32 Above-mentioned interaction.

But the attribute of brush 12 keeps identical.Brush 12 preferably has the diameter in the range of 20 to 80mm, and Drive device may can rotate brush 12 with least 6000 rpms of angular speed.The width of brush 12 is i.e. in brush 12 The size of the brush 12 extended in the direction of brush axle 14 can be such as 25cm magnitude.

There is provided cluster 54 on the outer surface of the core parts 52 of brush 12.Each cluster 54 is referred to as brush member including hundreds of The fibre element of part 16.Brush element 16 can be every less than 150 grams in about 10 microns of magnitude and Dtex values by such as diameter The polymer manufacture of 10 kms.On the outer surface of the core parts 52 of brush 12, brush element 16 tie up density can be to Few 30 clusters 54 are every square centimeter.

It quite can confusedly arrange the mutual distance that brush element 16 is not fixed.In addition, mentioning the outer of brush element 16 Surface 56 can be uneven, and which enhance the ability of the capture liquid droplet 24 of brush element 16 and dirt particle 22.It is specific and Speech, brush element 16 can be so-called microfibre, and it does not have smooth or more or less circular periphery, but it has Coarse and more or less star-shaped periphery with groove.Brush element 16 need not be identical, as long as the brush element 16 of brush 12 Total most line mass density at least meet the requirement less than 150 grams of every 10 kms in tip portion 18.

By rotation brush 12, specifically by the brush element 16 of rotation brush 12, dirt particle is tidied up from surface 20 22 and liquid 24, and pass it in the collection position inside cleaning equipment 100.Due to the rotation of brush 12, with surface 20 occur to realize in first position at the time of initial contact.The degree increase of contact, until brush element 16 is with such a shape Untill formula is bent, wherein the tip portion 18 of brush element 16 contacts surface 20 in the curve form.The tip portion 18 is passed through Surface 20 is crossed to slide and run into dirt particle 22 and liquid 24 in the process, wherein such a case may be caused by meeting, In this case, remove from surface 20 to be cleaned and by brush element 16 based on adhesion take away a certain amount of liquid 24 and/or Dirt particle 22.In this process, brush element 16 can more or less similarly act as being used to capture and the He of traction particle 22 24 whip, the whip is force-closed formula and can be based on being maintained at particle 22,24 with the comparable function of the function of strap brake On.In addition, the liquid 24 tidied up can bring some liquid, wherein liquid line is kept in atmosphere, and liquid line is away from surface 20 It is mobile.The acceleration occurred in the tip portion 18 of brush element 16 causes during the rotation of brush element 16 when brush element and ground 20 when losing contact, and dirt particle 22 and liquid droplet 24 are released from brush 12 automatically.Due to can not be by vacuum collectors 38 Whole dirt particles 22 and liquid droplet 24 are directly sucked in, it is a small amount of dirty in brush element 16 loses the region of contact from surface 20 Thing and liquid are returned to unrestrained on surface 20.But, the influence for splashing surface 20 again is overcome by scraper element 32, wherein scraping Element 32 collects heavy the splashing liquid body and dirt by being used as a kind of sweeper, so that because the under-voltage of application can suck residue Liquid 24 and dirt 22.Therefore liquid 24 and dirt 22 will not be inhaled into and leave suction areas 34 again.

Due to selected technical parameter, brush element 16 is that, with soft scraping effect, this helps resist liquid on surface 20 The adhesion of body 24 and dirt particle 22 to surface 20.

As brush 12 rotates, mobile continuation of the brush element 16 on surface 20 finally loses contact until there occurs Untill moment.When no longer there is contact situation, it is desirable to which brush element 16 acts on brush element 16 in the rotation due to brush 12 On centrifugal force under the influence of assume the situation of original stretching, extension.Because when requiring to assume again that stretching, extension situation, brush element 16 is Bending, so occur the acceleration of additional stretching, extension at the tip portion 18 of brush element 16, wherein brush element 16 is from bending Situation is moved to stretching, extension situation, wherein, the movement of brush element 16 is suitable with the whip twitched.Acceleration at tip portion 18 At least 3000m/s is met when brush element 16 is almost assumed and is again at stretching, extension situation²Requirement.

During the movement under the influence of the power of tip portion 18 of brush element 16 is acted on, discharged from brush element 16 A large amount of dirt particles 22 and liquid 24, because these power are much larger than adhesion.Therefore, liquid 24 and dirt particle 22 are forced in the back of the body To being flown out in the direction on surface 20.Then most of liquid 24 and dirt particle 22 are sucked by vacuum collectors.By as above institute State scraper element 32 and generated in suction areas 34 it is under-voltage, it is ensured that liquid 24 and dirt 22 are returned to from brush 12 is unrestrained The remainder on surface 20 is also collected and is then absorbed into.

Under the influence of acceleration, liquid 24 can be discharged with small droplet.For for example by being used as rotatable air dirt What the centrifugal force fan of the vacuum fan collector 38 of separator specifically vacuum collectors 38 was performed further separated Cheng Eryan this be favourable.It should be noted that the power that suction force such as centrifugal force fan applies is not played the part of by brush member in above process Part 16 tidies up the role of liquid and dirt.But, these suction forces are for tidying up via the dirt and liquid for scraping collection Speech is necessary.

In addition to the function of foregoing each brush element 16, it can help be used to tidy up the He of dirt particle 22 Another effect of the process of liquid 24 is the capillary effect between brush element 16.On this point, with brush element 16 Brush 12 is based on capillary force and is absorbed by brush 12 equivalent to the brush 12 for immersing a large amount of coating, wherein coating.

From above, had the following properties that according to the brush 12 of the present invention：

- during the contactless part of the rotation of brush 12, by by centrifugal force by the soft cluster 54 with flexible brush element 16 Stretch；

- may be with being perfectly adapted to, because whenever soft cluster 54 contacts surface between brush 12 and surface 20 to be cleaned Soft cluster 54 will bend and be stretched whenever being possible to affected by centrifugal force when 20；

- due to sufficiently high acceleration force, brush 12 persistently cleans he itself, and this ensures lasting cleaning result；

- due to the low-down bending hardness of cluster 54, it is thermally generated minimum between surface 20 and brush 12；

- based on by cluster 54 rather than the fact that tidy up liquid 24 by air stream as in many conventional equipments, even in Occur fold or depression in surface 20, can also realize and be tidied up from the very stable liquid on surface 20 and very smoothly overall Cleaning result；And

- by cluster 54, dirt 22 is removed from surface with soft but effective manner, wherein the soft based on brush element 16 It can realize that maximally effective energy is used.

Relatively low value based on line mass density, it is also possible that brush element 16 has low-down bending hardness, And their original-shape can not be kept when being tied cluster 54.In conventional brush, brush element is upon discharge with regard to bullet Return.But will not be done so with the brush element 16 of low-down bending hardness as described above because elastic force it is too small so that The internal friction between each brush element 16 is no more than appeared in them.Therefore, cluster 54 will keep pleat after deformation Wrinkle, and only will be stretched when brush 12 rotates.

Compared with the conventional equipment including the hard brush for contacting surface to be cleaned, according to brush used in the present invention 12 can realize substantially preferably cleaning result, because such a operation principle, wherein being made according to the operation principle Liquid 24 and dirt 22 are tidied up with brush element 16 and brush element 16 removes liquid 24 and dirt 22 from surface 20 to be cleaned, its In liquid 24 and dirt taken away by brush element 16 before liquid 24 and dirt 22 contact surface 20 again in next circulation 22。

The result for the fact that be retracted due to brush 12 by surface 20 to be cleaned, brush 12 is used as a kind of gear pump, its The internal pump of air from mouth of pipe outer cover 28 is drawn onto outside.This is unfavorable effect, because the dirt on such a position The droplet that grain 22 was blown away and formed liquid 24, wherein on the position brush 12 can not touch liquid 24 and dirt 22 and Liquid 24 and dirt 22 may drop unexpected at the time of during cleaning process.

In order to compensate pumping effect as described above, it is proposed that with for being generated in the region that brush 12 is contacted with surface 20 The device of air stream, the air stream is used to compensate the air stream generated by brush 12.

These devices can be realized with various ways.May be shown in shown first embodiment in fig 1 and 2 One kind realization, wherein, small opening 58 is configured between mouth of pipe outer cover 28 and brush 12 at such a position, wherein at this Brush element 16 leaves mouth of pipe outer cover 28 during the rotation of brush 12 in position.The opening 58 is realized to the another of suction areas 34 Individual suction intake 60, it is in the region on the initial contact surface 20 of brush element 16 using under-voltage (by the institute in suction areas 34 State under-voltage).Such a air stream of generation that this is under-voltage, the air stream is offset due to the rotation of brush 12 during use in brush The undesired turbulent airflow generated before 12.

Offset the undesired turbulent airflow generated before brush 12 second is probably to be assembled to brush 12 The cluster 54 being arranged in rows on brush 12 of brush element 16, so that necessary pumping power will be significantly reduced.

In addition, shown in second embodiment as shown in Figures 3 and 4, it is possible to using deflector 62 come in rotation Brush 12 is apparently retracted in direction 26 at the position before brush 12 contacts surface 20.Deflector 62 has by deflecting brush member Part 16 is by the function pinched together of brush element 16.So, the air appeared in the space between brush element 16 is pushed out Go out the space.When brush element 16 is being movable away from one another again after leaving deflector 62, the space between brush element 16 Increase, so that air will be sucked into brush 12, wherein creating for aspirating the under-voltage of dirt 22 and liquid particles 24.This The air stream created by rotation brush 12 is compensated again.The PCT/IB2009/054333 and PCT/ signed in the applicant The example of the deflector is found in IB2009/054334.

Below equation can be used to calculate the air stream for needing to compensate：

Φ_c=π * f*W*F* (D*I-I²)

Wherein：

Φ_c=need the air stream (m of compensation³/s)

F=brushes frequency (Hz)

The width (m) of W=brushes 12

F=brush compensating factors (-)

The diameter (m) of D=brushes 12

I=brushes 12 are by the retraction (m) on surface 20

In actual example, f=133Hz, W=0.25m, D=0.044m and I=0.003m.On brush compensation because Son is it should be noted that determine the factor based on the experiment of the brush with feature as described above, and it was found that it is 0.4.Profit With described value, following compensation stream is found：

Φ_c=π * 133*0.25*0.4* (0.044*0.003-0.0032)=0.005015m³/s

Therefore in this example, it is favourable with about 5 liters of compensation airstreams per second.Can utilize in practice with On the realization that is illustratively described may in one kind particularly well realize the air stream, so as to actually eliminating brush The unfavorable pumping effect of son 12.
