Description
Technical field
The present invention relates in general to a kind of cleaner suction nozzle, and the base of this cleaner suction nozzle is connected with connector towards handle by hinged drive link.
Background technology
More known cleaner suction nozzles in the prior art, its base is hinged and is arranged on ground protruding component to be cleaned for adapting to.Such as, document EP0304609 describes the cleaner suction nozzle that a kind of base is rotatably connected with base, and base is connected with air-breathing handle by hinge bar.This mechanism to allow when suction nozzle to be pushed away by user or draws initiation air-breathing base towards a direction or the swing towards other direction.The shortcoming that this swing has causes the air leakage rising side, reduces the step-down in suction passage, and this affects scraping efficiency when covered ground has pile fabric, reduces because make base be fitted in ground dropping force.Scraping refers to the mechanism of base on the hair on the weaving ground that should clean.
Document EP0125994 also proposes a kind of air-breathing base suction nozzle hinged relative to oscillating nozzle.Suction nozzle also has roller or bearing washer, and it absorbs the hunt effect that the power of user when advancing also allows restriction base.On the contrary, when retreating, roller or base no longer include any effect and prevention base swing, make to produce air leakage in rise side, thus therefore the adhesive force on restriction ground also limit scraping efficiency.This only can occur with when singlehanded pulling handle when user, or with the hands catches handle when user and be applied for the power of drawing backwards and be applied for down even strengthening when making the power on roller laminating ground.In order to limit this hunt effect, the lock that can be activated by user is set between base and oscillating nozzle.This device is implemented complicated, because this mechanism has multiple assembly.In addition, this device is unfavorable for the ergonomicity of whole device, because user oneself must control lock when it finds that dust suction is not best when retreating.And lock is once locking, and just no longer make base have any free degree, base then loses its hinged characteristic, the scrambling on ground can not be adapted to again when advancing.User should lock base when retreating and unlock base when advancing in the worst case, and this is dry as dust especially, because must will carry out such operation back and forth each.
Summary of the invention
The object of the invention is the shortcoming of the document solving above-mentioned prior art, particularly, first provide a kind of simple cleaner suction nozzle, this cleaner suction nozzle has articulated base, allows to use and the air leakage under base of the dust collection efficiency that can not make a difference when advancing or when retreating.
For this reason, a first aspect of the present invention relates to a kind of cleaner suction nozzle, and cleaner suction nozzle has: base, and it is rotatably connected with connector towards dust catcher by drive link; And at least one bogie wheel on the ground, it is arranged on drive link, and base has at least one ground suction passage, and suction passage defines respectively at the scraping edge of front and rear by front scraping board and rear scraping board.Base also has stop mechanism on the ground at the rear portion of scraping edge, and stop mechanism is used for moving limit base backward at cleaner suction nozzle and rotates around drive link, and stop mechanism is set to allow air to pass through towards rear scraping edge.Therefore, the present invention allows the effective dust suction when advancing, because by stop mechanism, the accident limiting base swings, and this is avoided losing dust collection efficiency due to air leakage.When retreating, no matter user to the effect of handle (crosse) how (drawing or push-pull effort combination down only), swing is limited, because stop mechanism is set directly on floating mount.Finally, only just limit swing when moving backward, little scrambling when base keeps its locomitivity also can adapt in setback for the scrambling adapted to when advancing completely.Always never hinder the viewpoint of dust collection efficiency, stop mechanism according to the present invention is arranged to not damage the air stream sucked towards rear scraping edge.
Preferably, scraping edge limits one first scraping plane, and stop mechanism forms area supported, and this area supported is raised relative to scraping plane and opened by air duct and rear scraping fate.Simply, the maximum of the base pivots when moving backward provides according to the vertical distance making scraping plane and area supported separate, and makes front scraping board can not raise one and cause very high values to sucking the leakage be harmful to.
Preferably, stop mechanism also limits one second scraping plane, and this second scraping plane and first is swiped planar shaped angulation, and the summit at this angle is rear scraping edge.This geometry allows to ensure, when moving backward, the possible pivotable of tool simultaneously, when area supported and earth surface, the resistance of retrogressing is limited, because area supported and rear scraping edge are aligned.
Preferably, in the end of suction nozzle, the air channel width between rear scraping edge and stop mechanism at least equals 5% of the length of suction passage.Stop mechanism should not disturb the air stream towards rear scraping edge, and answers minimally to set this value freely to circulate for allowing air.The applicant confirms, and this value represents the good compromise of the geometric constraints being used for the total appearance and size meeting hydrodynamics requirement (speed, flow behavior, drag losses) and suction nozzle base.
A noticeable especially embodiment is, stop mechanism is made up of two supporters, and therefore forms two area supporteds, and these two area supporteds are configured in the end of suction nozzle and the rear portion of scraping edge, and are connected by attaching parts.Therefore a kind of systems stabilisation is obtained, because ground two supporters are separated from each other.
Preferably, the attaching parts of the area supported of base comprise towards the air duct of rear scraping board.These air ducts lead to the groove be configured between rear scraping edge and stop mechanism.
Preferably, the attaching parts between two area supporteds of base raise relative to area supported, pass through towards rear scraping edge to allow the air sucked by suction nozzle.Supplementing as the air duct between rear scraping edge and stop mechanism, this recess ensures that air is inhaled correctly along rear scraping edge.
Preferably, the profile of area supported is chamfering shape/or is spoke-like.This allows when suction nozzle moves backward, in stop mechanism and the earth surface limit resistance of motion.
A second aspect of the present invention relates to a kind of dust catcher, and this dust catcher comprises at least one suction nozzle described according to a first aspect of the invention.
Accompanying drawing explanation
By reading shown in accompanying drawing and the detailed description of the embodiment of the present invention provided as nonlimiting examples, more clearly other features and advantages of the present invention will be understood, in the accompanying drawings:
Fig. 1 illustrates according to cleaner suction nozzle of the present invention;
Fig. 2 illustrates the suction nozzle of the Fig. 1 when proper motion backwards;
Fig. 3 illustrates the detail drawing of the air-breathing base of the suction nozzle of the Fig. 1 used under the normal condition of advancing or retreat;

Detailed description of the invention
Fig. 1 illustrates cleaner suction nozzle 100, and cleaner suction nozzle 100 has air-breathing base (semelle) 10, and air-breathing base 10 is rotatably connected with connector 40 towards handle (not shown) by drive link 20 and flexible element 30.Base 10 has suction gap (or passage) 13, sucks gap 13 and defines respectively at the scraping edge of front and rear by front scraping board and rear scraping board.Each scraping board mainly comprises and the scraping edge of attacking inclined-plane and being connected.Drive link 20 has at least one supporting rollern 50 on ground 200, and supporting rollern 50 rotates around axle 23.Base can rotate around the rotating shaft 21 of drive link, and drive link also can rotate around the rotating shaft 22 be connected with connector 40.Therefore the adhesive force on the base 10 no matter produced by suction step-down on the whole surface of suction passage 13 how, and the articulated base 10 floating relative to connector 40 easily can adapt to the unevenness on ground 200, and cleaning works is more prone to.As a supplement, when suction nozzle advance the puck, roller 50 absorbs the vertical force transmitted by user, and only horizontal force is passed to base 10, base can be cleared the jumps and both do not blocked the swing that do not caused by the vertical force of user or gear is stung stop (arc-boutement).Therefore, two scraping edge 11 of suction passage 13 contact with ground 200 with 12, and ensure not to be drawn in suction passage with having improper leakage, this allows effectively cleaning.
Fig. 2 illustrates the suction nozzle 100 when setback, when user standard and predetermined height (namely overhead 800mm) holds handle time: roller 50 raises from ground, and axle 21 allows to ensure relative to the location of suction passage 13 in this case, the direction of the power of base 10 is applied to together with the improper swing that can not be caused base 10 by the adhesive force sucking step-down generation by drive link 20, and therefore improper swing can produce air leakage, thus cause the minimizing of step-down, and therefore cause the minimizing of adhesive force and scraping efficiency.
Fig. 3 is shown specifically base 10, and now, under the standard conditions of Fig. 2, suction nozzle is pushed away when advancing or drawn when retreating.Base 10 is contacted with ground 200 with 12 by two scraping edge 11, and this ensures not air leakage improperly, thus makes dust collection efficiency best.In order to not disturb the work under this regular service conditions, area supported 15 does not answer kiss the earth, for this reason, and area supported 15 rising minimum relative to ground distance d1.Area supported 15 is also relative to ground 200 or scraping planar tilt, and this scraping plane comprises two scraping edge 11 and 12.Selection is the minimum point in order to make the plane comprising area supported 15 comprise rear scraping edge relative to scraping planar tilt.Reason according to this Standard Selection angle α is described in the relevant paragraph of Fig. 4.
Fig. 4 illustrates base 10, and now, suction nozzle 100 moves backwards and is not the standard conditions of Fig. 2.Such as, user towards post-tensioning suction nozzle 100, but applies a vertical power down to suction nozzle simultaneously.In the configuration, the structure of suction nozzle then causes opposing torque on base 10, and before therefore this opposing torque can make, scraping edge 11 departs from ground 200.Keep flow and pressure in order to avoid this situation, area supported 15 contacts with ground 200 and the swing of base 10 is restricted to maximum pivotable.As a result, front scraping edge 11 than the maximum pivotable rising of this shown in Fig. 4 get Geng Gao, thus can not be limited in the air leakage flow under leading edge 11.In addition, the existence of area supported 15 should not hinder the air mass flow entered by rear scraping edge, Here it is why air duct 16 be configured in the cause between rear scraping edge 12 and bearing washer 15.This passage 16 should have Breadth Maximum at the both ends of suction nozzle 100, because be maximum at these local flows.Finally, when moving backwards, when base 15 is against time on the ground, the resistance to motion should be limited.For this reason, area supported 15 is aimed at the minimum point i.e. rear edge 12 of swiping of rear scraping board.As can be seen here, area supported 15 and scraping planar shaped angulation α, the summit of this angle α is rear scraping edge 12.Like this, when moving backwards, base 10 is outstanding towards ground between area supported 15 and rear scraping edge 12 without any element (these elements can apply resistance to base slip on the ground).As a supplement, always hinder the viewpoint of the power of the movement of suction nozzle 100 from restriction, the edge of area supported 15 is spoke-like or chamfering shape.
Should be appreciated that, concerning those skilled in the art, when not departing from the scope of the invention of claims defined, obvious various change and/or improvement can be carried out to the embodiments of the present invention described in this description.Particularly, the present invention refer to the slidably supported surface for realizing against function, but can consider use roller or wheel realize roll against.
