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 through hinged drive link.
Background technology
More known in the prior art cleaner suction nozzles, its base are hinged to be used for adapting to and are arranged on ground protruding component to be cleaned.For example, document EP 0304609 has been described the cleaner suction nozzle that a kind of base is rotatably connected with base, and base is connected with air-breathing handle through hinge bar.This mechanism allows when suction nozzle is pushed away by the user or draws, to cause air-breathing direction of base court or towards the swing of other direction.The shortcoming that this swing has is that the air that cause to rise side leaks, and reduces the step-down in the suction passage, and this is coated with influence scraping efficient under the situation of pile fabric on ground, reduce because make base be fitted in ground step-down power.Scraping is meant the mechanism of base on the hair on the weaving ground that should clean.
Document EP 0125994 also proposes a kind of air-breathing base suction nozzle hinged with respect to oscillating nozzle.Suction nozzle also has roller or bearing washer, the hunt effect that it absorbs the power of user when advancing and allows the restriction base.On the contrary, when retreating, roller or base no longer include any effect and do not stop the base swing, make that producing air in the rise side leaks, thus the applying power on restriction ground and so restriction scraping efficient.This can take place under only with singlehanded situation about pulling handle the user, perhaps with the hands catches handle and towards the after-applied power that is used to draw and apply under the situation of the power that is used to make roller applying ground down even can strengthen the user.In order to limit this hunt effect, between base and oscillating nozzle, being provided with can be by the lock of user's actuating.This device is implemented complicated, because this mechanism has a plurality of assemblies.In addition, this device is unfavorable for the ergonomicity of whole device, because user's dust suction when it finds to retreat is not must own control to lock under the best situation.And in case the lock locking just no longer makes base have any free degree, base then loses its hinged characteristic, can not when advancing, adapt to the scrambling on ground again.The user under the worst situation, should when retreating, lock base and when advancing the release base, this is dry as dust especially, because must all will carry out such operation back and forth at each.
Summary of the invention
The objective of the invention is to solve the shortcoming of the document of above-mentioned prior art; Particularly; A kind of simple cleaner suction nozzle at first is provided, and this cleaner suction nozzle has hinged base, allows when advancing or uses when retreating and the air under base of the dust collection efficiency that can not make a difference leaks.
For this reason, 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 through drive link; And at least one bogie wheel on the ground, it is installed on the drive link, and base has at least one ground suction passage, and suction passage is forwardly defined by the scraping edge with the rear portion.Base also has stop mechanism on the ground at the rear portion of scraping edge, and stop mechanism is used for when cleaner suction nozzle moves backward, limiting base around the drive link rotation, and stop mechanism is set to allow air, and the scraping edge passes through towards the back.Therefore, the present invention allows the effective dust suction when advancing, because by stop mechanism, has limited the accident swing of base, and this is avoided losing dust collection efficiency owing to air leaks.When retreating, no matter the user is to the effect of handle (crosse) how (drawing or down push-pull effort combination only), swing is limited, because stop mechanism is set directly on the base that floats.At last, only when moving backward, just limit swing, base keeps its locomitivity to be used to adapt to the scrambling when advancing fully and can adapt to the little scrambling when setback.Always never hinder the viewpoint of dust collection efficiency, stop mechanism according to the present invention is arranged to not damage the scraping edge inhaled air stream towards the back.
Preferably, the scraping edge limits the scraping plane, and stop mechanism forms area supported, and this area supported raises with respect to the scraping plane and opens through air duct and back scraping fate.Simply, the maximum of the base pivots when moving backward is according to the scraping plane is provided with the vertical distance that area supported separates, and scrapes wiping board before feasible and can not raise one and cause sucking the very big value of harmful leakage.
Preferably, stop mechanism limits second plane, and this second plane and first plane form the angle, and the summit at this angle is a back scraping edge.This geometry allows assurance, when moving backward, and the pivot that has possibility simultaneously, when area supported contacted with ground, the resistance of retreating was limited, because area supported is aimed at back scraping edge.
Preferably, in the end of suction nozzle, the air duct width between back scraping edge and stop mechanism equal at least suction passage length 5%.Stop mechanism should not disturb the air stream of the scraping edge towards the back, and answers this value of minimally setting to be used to allow air freely to circulate.The applicant confirms, and this value representation is used to satisfy the good compromise of geometric constraints of total appearance and size of hydrodynamics requirement (speed, flow behavior, drag losses) and suction nozzle base.
A noticeable especially embodiment is that stop mechanism is formed by two area supporteds, and each end that these two area supporteds are configured in suction nozzle is connected with the rear portion of scraping edge and through connector.Therefore obtain a kind of systems stabilisation, because ground two supporters are separated from each other.
Preferably, the connector of the area supported of base comprise towards after scrape the air duct of wiping board.These air ducts lead to the groove that is configured between back scraping edge and the stop mechanism.
Preferably, the connector between two area supporteds of base raises with respect to area supported, and the scraping edge passes through towards the back by the suction nozzle inhaled air to allow.As replenishing of the air duct between back scraping edge and stop mechanism, this recess guarantees air, and the scraping edge is sucked by correct along the back.
Preferably, the profile of area supported is a chamfering shape/or be spoke-like.This allows when suction nozzle moves backward, the restriction resistance of motion when stop mechanism contacts with ground.
Second aspect of the present invention relates to a kind of dust catcher, and this dust catcher comprises at least one described according to a first aspect of the invention suction nozzle.
Description of drawings
Through the detailed description of the embodiment of the present invention of reading shown in the accompanying drawing and providing as non-limiting embodiment, will more clearly understand other features and advantages of the present invention, in the accompanying drawings:
Fig. 1 illustrates according to cleaner suction nozzle of the present invention;
The suction nozzle of Fig. 1 when Fig. 2 is illustrated in proper motion backwards;
Fig. 3 is illustrated in the detail drawing of air-breathing base of the suction nozzle of the Fig. 1 that uses under the normal condition of advancing or retreating;
Fig. 4 is illustrated in the detail drawing of the air-breathing base of the suction nozzle of Fig. 3 of use under the specified conditions of retreating.
The specific embodiment
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) through drive link 20 and flexible element 30.Base 10 has suction slit (perhaps passage) 13, sucks slit 13 and forwardly defines by scraping wiping board with the rear portion.Each is scraped wiping board and mainly comprises and attack the scraping edge that the inclined-plane is connected.Drive link 20 has at least one supporting rollern 50 on ground 200, and supporting rollern 50 is around axle 23 rotations.Base can rotate around the rotating shaft 21 of drive link, and drive link also can be around the rotating shaft that is connected with connector 40 22 rotations.Therefore no matter on the whole surface of suction passage 13 by suck on the base 10 that step-down produces applying power how, the hinged bases 10 that float with respect to connector 40 can adapt to the unevenness on ground 200 easily, and cleaning works is more prone to.As replenishing; When the suction nozzle advance the puck; Roller 50 absorbs the vertical power of being transmitted by the user, and only horizontal force is passed to base 10, makes base to clear the jumps and swing or gear that the vertical power by the user of both not blocked not causes are stung stop (arc-boutement).Therefore, two scraping edge 11 of suction passage 13 contact with ground 200 with 12, guarantee not to be drawn in the suction passage with having improper leakage, and this allows effectively cleaning.
Fig. 3 is shown specifically base 10, and at this moment, under the standard conditions of Fig. 2, suction nozzle is pushed away when advancing or when retreating, drawn.Base 10 contacts with ground 200 with 12 through two scraping edge 11, and this guarantees that not air leaks improperly, thereby makes dust collection efficiency best.In order not disturb the work under this regular service conditions, area supported 15 is not answered kiss the earth, for this reason, area supported 15 with respect to the minimum rising in ground apart from d1.Area supported 15 also tilts with respect to the ground 200 or the plane of swiping, and this scraping plane comprises two scraping edge 11 and 12.It is in order to make the plane that comprises area supported 15 comprise the minimum point of back scraping edge that selection is tilted with respect to the scraping plane.Reason according to this Standard Selection angle α is described in the relevant paragraph of Fig. 4.
Fig. 4 illustrates base 10, and at this moment, suction nozzle 100 moves backwards and is not the standard conditions of Fig. 2.For example, the user is towards post-tensioning suction nozzle 100, but simultaneously suction nozzle applied a vertical power down.In this configuration, the structure of suction nozzle then causes opposing torque on base 10, and scraping edge 11 broke away from ground 200 before therefore this opposing torque can make.For fear of this situation and keep flow and pressure, area supported 15 contacts with ground 200 and the swing of base 10 is restricted to maximum the pivot.As a result, preceding scraping edge 11 can be than this maximum pivot rising De Genggao shown in Figure 4, thereby is limited in the air leakage flow under the leading edge 11.In addition, the existence of area supported 15 should not hinder the air mass flow that gets into through back scraping edge, and Here it is, and why air duct 16 is configured in the cause between back scraping edge 12 and the 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.At last, when moving backwards, when base 15 against on the ground the time, should limit resistance to motion.For this reason, area supported 15 with after scrape wiping board the i.e. back scraping of minimum point edge 12 aim at.This shows that area supported 15 forms angle α with the scraping plane, the summit of this angle α is a back scraping edge 12.Like this, when moving backwards, base 10 has no element (these elements can apply resistance to base slip on the ground) outstanding towards ground between area supported 15 and back scraping edge 12.As replenishing, always hinder the viewpoint of the power that moves 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, can under the situation of the scope of the invention that does not break away from the accompanying claims defined, carry out tangible various change and/or improvement the embodiment of the present invention described in this specification.Particularly, the present invention has mentioned the sliding bearing surface that is used to realize against function, but can consider to use roller or wheel realize rolling against.
