Description
Technical field
The present invention relates generally to that a kind of base has improved the cleaner suction nozzle of dust collection efficiency.
Background technology
Known to the dust suction of the controlled dust collecting system of a kind of parameter as object to be provided in the prior artDevice suction nozzle. Document GB1458899 has provided a kind of cleaner suction nozzle, the base of this cleaner suction nozzleHave suction passage, this suction passage is defined by flexible thin sheet at front and rear. These thin slices canUnder effect with the vertical supporting force to base that generates in step-down by passage, deform. ?When distortion, these thin slices change the active surface of passage and regulate supporting force, to allow with constantPower scraping weaving ground. Scraping refers to the mechanism of base on the hair on the weaving ground that should clean.
Above-mentioned system particularly has the not high enough shortcoming of operating efficiency. In fact, this system onlyBase adhesive force is on the ground worked, to cause the reaction to scraping. But this systemCannot ensure that the air mass flow entering in suction passage is enough to drive particle to be sucked at all. EvenCan notice, deformable piece is adopted made of plastic, will harden also in process in its service lifeNo longer suitable distortion, makes the live part of passage more, makes supporting force than the needs of initial specificationMuch bigger, this has limited the air mass flow of process under thin slice. As a result, reduced dust collection efficiency.Also be appreciated that, the document has proposed to be equipped with the suction nozzle of roller, these rollers ensure on ground andMinimum clearance between the lower surface of base. Therefore, these rolling elements are forced for air mass flowMinimum by surface, no matter the pressure in suction passage how, these rolling elements are in weaving simultaneouslyOn ground, use inconvenience, because the barrier that their diameter is not suitable for running into. Finally, makeMake nozzle structure complicated and expensive with these parts. Obviously, above-mentioned base does not allow ensureing with footEnough impurity inlet flows reduce motor power (output) when scraping in weaving ground.
Summary of the invention
The object of the invention is the shortcoming of the document that solves above-mentioned prior art, particularly, first carryFor a kind of simple cleaner suction nozzle base (semelle), this base allows to ensure in the time that suction nozzle movesEffective dust suction on weaving ground and easy to use.
For this reason, first the present invention relates to a kind of cleaner suction nozzle base, and base has at least one groundFace suction passage, suction passage is defined by the edge of swiping at front and rear. Base comprises for restrictionThe mechanism of base thrust on the ground, this mechanism with for to being drawn into the sky in suction passageThe governor motion that the flow rate pressure of gas regulates (couplepression-d é bit) interacts,Pre-determine the drag losses (pertedecharge) of the air of process under front scraping edge. ByThe governor motion regulating for pressure to the air in suction passage and flow is logical by suckingThe adhesive force that pressure in road produces ensures effective scraping on ground to be cleaned, on the other hand, and flowBe enough to rotating band and suck particle. Make the easy to use easy of suction nozzle for limiting the mechanism of thrust,Simultaneously also participate in determining pressure in the suction passage of suction nozzle and the value of flow. Finally, governor motionAlso participate in restriction for making the power of base motion, distribute adhesive force simultaneously and guarantee that this adhesive force is notVery large.
Preferably, scraping edge limits scraping plane, and, for to being drawn in suction passageThe flow pressure of air comprises sealing plate to the governor motion regulating, and sealing plate is included in scrapingIn plane and defined by front scraping edge. Drag losses is true with plain mode according to the width of sealing plateFixed, because air is forced through weaving to be cleaned ground. This plate allows contact force to distribute to and treatCleaning weaving ground, this has limited the power that should be applied by user in the time that suction nozzle moves.
Preferably, attack inclined-plane for limiting before the mechanism of base thrust on the ground comprises(chanfreinsd ' attaqueavant), the front front portion of attacking inclined-plane and be arranged in sealing plate. This is simply realExecuting the effect having is, in the time that suction nozzle is pushed away, limits thrust forward, but be arranged in plate beforeFace also allows to guide the air sucking the air mass flow that ensures process under plate to allow correct suctionEnter particle.
Preferably, for limit base setback force on the ground after attack inclined-plane and be arranged in rear scrapingAfter edge. This simple effect of implementing to have is, in the time that suction nozzle is drawn backwards, and restriction setback force,But be arranged in the air that also permission guiding sucks of rear scraping edge below and ensured in rear scrapingUnder edge, the air mass flow of process allows the correct particle that sucks.
Preferably, suction passage has a length L c, and plate has a width Lp, this widthLp is greater than the value being limited by formula Lp > 570/Lc. Under plate, the drag losses of the air of process existsIn the whole length of suction passage, be assigned with. This suction passage is longer, and the resistance of per unit length damagesLose just less. For this reason, this formula that defines the minimum of a value of the width of plate allows this width of amendment,This width is directly controlled drag losses. Fluid machinery is tested and experiment shows, too narrow plate is not suitable forIn pre-determining enough drag losseses.
Preferably, front attack He Hougong inclined-plane, inclined-plane and scraping plane form between 10 ° and 20 °Angle, and the front He Hougong inclined-plane, inclined-plane of attacking is at itself and relative end and the arcuate member of scraping edge(rayon) connect. The scope of this inclined-plane angle of attack value allows not only to ensure the ease of use of increase,And ensure correct flow, to allow gratifying dust collection efficiency. Below 10 °, inclined-planeConstrained motion power, but too much limited flow, more than 20 °, is conducive to air mass flow, but useVery large in the thrust that base is moved.
Preferably, front arcuate member of attacking inclined-plane between 1 millimeter and 4 millimeters, and after attack tiltedlyThe arcuate member of face is between 2 millimeters and 8 millimeters. Here equally, be arranged in inclined-plane endThe value of arcuate member allows to reduce the resistance to motion, but also allows to guarantee to realize the flow of effective dust suctionValue.
Noticeable especially one implements to be, sealing plate has between 4.5 millimeters and 5.5 millimetersBetween width, and before attack He Hougong inclined-plane, inclined-plane with scraping plane form between 13 ° and 17 °Between angle. The applicant confirms, uses the value within the scope of this, the dust suction on weaving groundEffective especially.
The invention still further relates to a kind of dust catcher, this dust catcher comprises that at least one is above-mentioned according to thisBright suction nozzle base.
Brief description of the drawings
By reading shown in accompanying drawing and the embodiment of the present invention providing as non-limiting embodimentDescribe in detail, will more clearly understand other features and advantages of the present invention, in the accompanying drawings:
Fig. 1 illustrates according to the profile of cleaner suction nozzle base of the present invention.
Detailed description of the invention
Fig. 1 illustrates the profile of the cleaner suction nozzle base 100 for cleaning weaving ground. Base100 have the whole suction passage of arranging along base 100 10. This passage in front portion by front scrapingEdge 11 defines, and is defined by rear scraping edge 12 at rear portion. By the air-breathing generation of duster motorStep-down in suction passage 10 and air mass flow have particularly according to imposing on and enter into suction passageThe drag losses of the air stream in 10 carrys out definite value. This drag losses depends on air flow path,This path is to specify according to the profile of base 100. The air stream entering by front is front being scrapedWipe process under edge 11, but also under sealing plate 20, pass through. Sealing plate 20 is included in by twoIn the scraping plane that individual scraping edge 11 and 12 limits. The width of the sealing plate 20 contacting with ground is wantedAsk at least process weaving ground on the corresponding width of plate 20 of air stream. Therefore, the width of plate 20More increase, drag losses just more increases, and therefore, the pressure in suction passage 10 just more reduces. KnotReally, the adhesive force being produced on base by atmospheric pressure increases, and by front scraping edge and rear scrapingThe scraping on 11 and 12 pairs of ground of edge increases. But the width value of plate 20 should be very not large, because shouldThe particle taking out from fiber by scraping edge 11 and 12 is inhaled into subsequently, for this reason, should makes instituteThe flow of air amount has minimum of a value. In addition, it is also noted that, plate 20 distributes laminating on the groundPower, has therefore limited base to the insertion in weaving ground and for promoting the needed power of suction nozzle.Move upward in order to be also convenient to base 100, inclined-plane 25 is arranged in the anterior of plate and with arcuate member 26Stop. Due to its juxtaposition onboard, inclined-plane 25 will pass through except reducing under plate 20The resistance of fiber on weaving ground beyond, also guide air and the drag losses of institute's inlet flow risenEffect. The parameter that the process of air stream is exerted an influence is the angle α that inclined-plane 25 becomes with scraping planeAnd the length on inclined-plane 25. At the rear portion of suction passage 10, scraping edge 12 is connected with inclined-plane 35,Inclined-plane 35 stops with arcuate member 36. Power when inclined-plane 35 is limited in base 100 and retreats, allows the endMao contacting gradually of seat and weaving ground to be cleaned, but the length on inclined-plane 35 with and with scrapingThe angle β that plane becomes also exerts an influence to the air mass flow entering by the rear portion of suction passage 10.
