Description
Technical field
The present invention relates to a kind of suction nozzle of dust catcher, especially hardstand suction nozzle, it has the suction nozzle head and a nozzle body that the suction nozzle head is connected with a dust catcher placed on the ground, wherein a tube connector of structure and this suction nozzle can be mobile or removable by slidingsurface together with the operation wheel on nozzle body, in nozzle body, be provided with a suction channel, it extends through nozzle body from tube connector, feeds then in the suction nozzle head.
Background technology
The suction nozzle of the dust catcher of the above-mentioned type is known.In order to handle the suction nozzle that hardstand has proposed the hardstand suction nozzle of relative configurations and has been provided with relative configurations in order to handle carpet, and the bristle that preferably has a rotation rolls with regard in this respect.Verified special suction in alcove in this known suction nozzle, perhaps walk around object, all be debatable, and have only by the user and could realize a kind of troublesome operations of dust catcher as the suction of chair legs or table leg and along the suction of pin bar or analog.Therefore, a gratifying suction operation along the pin bar is in principle only with realization like this, and promptly this suction nozzle moves along the pin bar transverse to the common pumping direction ground of being scheduled to by the operation wheel with its preceding arris.This transverse movement needs to consume more power for the user.When the opening size of an alcove is significantly less than the suction nozzle width, can not finish suction operation with known suction nozzle, sometimes must change slit-type suction nozzle or other similar suction nozzle for this reason.
Summary of the invention
At previously described prior art, a technical problem to be solved by this invention is, the cleaner suction nozzle of described type is done expansion design in an advantageous manner, for example improving edge suction work, and suction nozzle is more convenient near corner and alcove along the pin bar.
This problem at first and basically solves by the described technical scheme of claim 1.Wherein, described suction nozzle head is deflectable with respect to nozzle body.The suction nozzle of a described type is provided based on this organization plan, different with known (body) formula structure, it is made up of two mutual deflectable parts, that is forms by the nozzle body that is connected with dust catcher by tube connector with respect to the deflectable suction nozzle head of this nozzle body.Improve the flexibility of suction nozzle thus.In order to aspirate corner or alcove and for edge suction, for example along the suction of pin bar, this suction nozzle head can be placed on the position for this work the best.This suction nozzle head for along the edge suction of pin bar with regard to deflection on such position, at this moment, the preceding arris of suction nozzle head is directed to the pin bar and parallels, and with the common pumping direction of dust catcher or moving direction at an angle, for example move along the pin bar perpendicularly.Therefore this nozzle body then remains in its common suction or moving direction, continues to move along the orientation of moving direction by suction nozzle head that has been deflected and the operation wheel by nozzle body, and edge suction does not need the additional more power that expends for the user.Preferred in addition, this suction nozzle head can be automatically with respect to nozzle body deflection under situation about colliding with an entity such as pin bar or chair leg.So just can realize walking around object such as chair legs or table leg easily and aspirate, suction nozzle this moment (head) just can be walked around the object operation that is in the distance based on its deflection when dust catcher moves (preceding and back motion) by general dust suction direction.And the suction operation in alcove also has been simplified by solution of the present invention.At bump, under the arris situation, the suction nozzle head just automatically deflects into a corresponding position in the proal process of dust catcher, thereby allows suction nozzle to sail in the alcove before the especially eccentric bump suction nozzle head.Verified herein particularly advantageous is also can aspirate dark alcove according to two element type suction nozzles of the present invention.Therefore and can around furniture pin base and barrier make things convenient for and special suction (dedusting), keep this moment the working method (only forward and motion backward, without lateral movement) of custom just can realize conveniently and automatically be adapted to environment on every side.In a decision design of technical solution of the present invention, this deflection constitutes by a joint with a drag articulation axle.This joint is run through by the suction channel that nozzle body extends from tube connector by described, in addition the suction nozzle head side in joint preferably this suction channel mouth be formed in the suction nozzle head.About this also suggestion in addition, this suction nozzle head is deflectable in a horizontal plane.Based on this, the deflection of this suction nozzle head neither influences its plane positioning and does not also influence the orientation angle of dust catcher with respect to suction nozzle, does not therefore require that also the user makes corrective action under a deflection situation of suction nozzle head.In addition also the suggestion, this suction nozzle head when the state that is deflected, extend in part in nozzle body below.Based on this, this suction nozzle head has the section disappearance of a part of portion at least in a zone that is covered by nozzle body in the state that is deflected.This free space that allows the suction nozzle head to be transferred to the nozzle body below will so be selected in addition, promptly allow at least this suction nozzle head to the deflection of initial normal position, wherein in the zone of fixing nozzle body, the Breadth Maximum of this suction nozzle can not be exceeded by the deflection of suction nozzle head.In order further to improve the swabbing action suggestion in alcove, this suction nozzle head has a width bigger than the degree of depth (development length on the traffic direction) development length of traffic direction (that is transverse to) on the normal position.This suction nozzle head have bigger width be used to aspirate big surperficial desirable.But then should be able to provide a less width transverse to traffic direction in order to aspirate alcove.This hope just has been satisfied by suction nozzle head small depth, and when the suction nozzle head was on the position of 90 ° of deflections, its width was exactly the degree of depth of suction nozzle head when initial position.The width of therefore preferred this suction nozzle head is greater than the twice of suction nozzle head depth capacity.For example the ratio of the suction nozzle head width and the suction nozzle head degree of depth may be prescribed as 3: 1.In an exemplary width is under the situation of 300mm, and a depth capacity is defined as about 100mm.Also suggestion in addition, the degree of depth of suction nozzle head is different on the width (direction) of suction nozzle head.Therefore verified particularly advantageous is that this suction nozzle head has the profile of a circular sector.For this reason, preferably provide one on the normal position transverse to the operation (moving) direction linearly extended before arris; Thereafter arris is made of a circular arc line that the both ends of arris before this linearity are coupled together.This change circle structure of suction nozzle head is verified to be favourable in operation, special under the situation that the suction nozzle head outwards produces from narrow alcove.In addition, by the narrow structures of suction nozzle head on depth direction, also additionally improved the suction degree of depth in alcove.In addition more advantageously, this joint is built in the zone of suction nozzle head depth capacity.Whether just total energy obtains an identical suction nozzle head deflection thus, and clashed into irrelevant on the left side or its right in joint by an object with this suction nozzle head.In another organization plan of technical solution of the present invention, stipulate, but the suction nozzle head is with respect to 360 ° of nozzle body deflections or more.Based on this, this suction nozzle head preferably can rotate arbitrarily, so that get back to its initial normal position again after rotating 360 °.Suggestion in addition, the suction nozzle head one or more preferred-inflection point is by snap-lock, for example can make the buckle nose of spring-loaded for this reason, slip nose or rolling body are presented in the buckle groove of relative configurations.In a preferred construction scheme, advise like this, this suction nozzle head wants snap-lock on a position with respect to 90 ° of the normal position preceding arris of this straight line (this moment transverse to common traffic direction orientation) deflections or 270 °, this by the position of snap-lock on, this suction nozzle head is deflected in such a manner, and promptly its (with respect to width) small depth for example is oriented on the traffic direction in order to aspirate alcove.The suction nozzle head is preferably on 0 ° and the 180 ° of positions by snap-lock, and this suction nozzle head is by so directed on this position, and promptly to extend (length) be directed that is be positioned on the normal position transverse to the direction of motion to its width.Also have so possible scheme in addition, promptly be provided with more than two by the inflection point of snap-lock, for example be the position of 90 ° of 4 mutual dislocation for this reason.Verified one is that this suction nozzle head is rotating back under the spring-loaded on a basis or the snapped-in position after deflecting into a centre position as particularly advantageous organization plan.For example this nozzle body can be conditioned with spring force best on the operating technology with respect to the suction nozzle head for this reason, wherein for example this extend into suction channel in the suction nozzle head and that run through this joint and can have a planform off-centre or oval and have the buckle nose, and this structure can realize a rebound effect by a spring element.Also have this possibility scheme in addition, wherein by pulling force (spring), pressure (spring) or leaf spring produce a simple relative elastic force effect.As preferably, on the position of 0 ° and 180 °, this position is corresponding to the normal position by the elastic force snaps into position for the suction nozzle head.These two positions are corresponding to standard application position that is surface (ground) suction.Preferably (that is being deflected 90 ° operating position from this relative normal position) always can automatically be moved back into this normal position again to this suction nozzle head under the spring support from each other centre position.This spring support effect of being advised also can provide by a corresponding elastic properties of materials in joint area in addition.In an other preferred structure scheme, can stipulate for this reason, a spring that stretches the extending element form is set, this spring transverse to suction channel extend in the suction nozzle head.For example can settle a spring steel that stretches extension in the suction nozzle head, it so acts on this suction nozzle head for this reason, and promptly a spring torque of setting up when the deflection of suction nozzle head realizes that the suction nozzle head resets to entopic.This normal position of suction nozzle head is to aim at by orientation zero deflection, that stretch of this spring element to limit.Advantageously verified herein, this spring that is set up is to be maintained in the suction nozzle head and to act on the suction channel that runs through the suction nozzle head of nozzle body.Stipulate also that for this reason this spring runs through this suction channel.Conduct herein is preferred, and the end face lateral edges arris that this spring element that stretches is parallel to the suction nozzle head comes directed the aligning, and this is to run through under the situation of suction channel cross section at about middle ground.For this reason this suction channel wall be provided with diametrically directed perforate for spring run through with or the groove that is provided with corresponding orientation to admit the spring segmentation, in order that the suction nozzle head makes that with respect to a deflection of nozzle body stretching out the suction channel wall in both sides is maintained at spring segmentation flexural deformation in the suction nozzle head.Produce a moment of torsion that back drives thus, its with towards entopic directive effect to the suction nozzle head.Also can design like this according to another selection scheme, promptly spring is connected with suction channel, and wherein this spring does not preferably run through this suction channel.A free end of this spring is maintained in the zone of suction channel wall for this reason, for example is fixed in the boring of a corresponding orientation or in the groove.Encapsulated injection moulding is wherein in the process of making the suction channel wall to be also contemplated that spring end freely.And have this feasible program, and wherein, this spring runs through the wall construction of this suction channel in positive secant mode, and what can expect in addition is that this spring runs through this suction channel wall in both sides with positive secant or only extends according to this in a side for this reason.In a preferred expansion flexible program, stipulate that this spring is fitted on this suction channel by the part of suction channel wall in a circumferential direction.For this reason, spring segmentation that affacts on the suction channel wall just can be presented in the groove of an annulus segmentation shape of this wall construction.And can expect in the process of making the suction channel wall, injection moulding being sealed in this spring segmentation as another kind of selection scheme herein.Also suggestion, the opposed supporting member that is used for spring is built into the suction nozzle head in the suction channel outside.So for example can be arranged on guide pins or the analog that settle the spring both sides.And proved that about this favourable organization plan is, and this spring is maintained in the grooved area, and this grooved area is shaped as an outside gauge that is used for spring when the state that is deflected.Thus, just can influence the characteristic curve of this spring by this recess edge-structure in simple mode.Advantageously verified with the structure configuration-independent ground of supporting member in addition, this spring is can be free-moving with respect to a supporting member.But also suggestion is provided with two springs.For example these springs can extend on equidirectional ground on base position for this reason.But can stipulate also that as another kind of replacement scheme these springs oppositely extend mutually on base position.This all is that the organization plan of a uniform reset torque is so improved during not only towards a direction deflection time but also in deflection to another way, and promptly this spring is aimed at symmetrically.Also suggestion is configured to the sheet spring with described spring in addition.Can be spring steel as spring material herein, glass fibre and corresponding plastics.Have again, also can form the elastic characteristic curve of a hope by the geometry (width, thickness) of sheet spring.Be reduced to a minimum of a value for making, in a preferred construction scheme, advise that this sheet spring has the cross section of a bending with respect to zero position that is entopic hysteresis characteristic.This sheet spring just can be made by a kind of metallic plate or steel plate of moulding like this.Described spring preferably has the ridge structure of a sphere shape.Therefore, such sheet spring just can be crooked perpendicular to longitudinal direction ground in the plane of this section bar (Profil).By (corrugation shape) sheet spring of such moulding, this suction nozzle head just always is turned back to an accurate zero position and is one and resembles by the stable zero position of snap-lock.According to aforementioned solution, providing the moment of torsion that under involved zero position snap-lock, can reply (regressive) to form under the less number of components.This has just realized a spring mechanism that performance is reliable, with low cost, and the member that it need not add just comprises one zero (position) snap-lock.Similarly produce recoverable and a do not add up moment of torsion according to this, this point also need not other structural measure or member.Stipulate that in another organization plan of technical solution of the present invention this suction nozzle head has one or more scrub-brush segmentations at bottom side, it is used for the gauge suction chamber especially under hardstand suction nozzle situation.For also can below the object for example below soft chair or analog ground to be processed relatively carry out the special suggestion of suction operation with less relatively spacing, the height of suction nozzle head (with respect to the free vertical development length of the bristle of a scrub-brush segmentation) comprises that this scrub-brush will be equivalent to 2 to 5 times of the free vertical length of this bristle.Be that a height gage of this suction nozzle head is decided to be 20～50mm under about 10mm situation in general free bristle length like this.Can be implemented in the object below of reserving a free space in simple mode according to this and carry out suction operation.Suggestion at this point in addition, the depth capacity of this suction nozzle head is corresponding to 3-6 times of this suction nozzle head height degree.But also regulation, this nozzle body is supported on the suction nozzle head on the one hand and is supported in this on the other hand and is installed on the operation wheel or slidingsurface on the nozzle body.In order to realize that an elongated version especially advises that for the suction in alcove this nozzle body has such width in the zone of suction nozzle head, it is corresponding to a fraction very of suction nozzle head width.Stipulate in a preferred embodiment that for this reason the width of this nozzle body corresponding to 1/3 to 1/5 of suction nozzle head width, is just to be about 60mm under the 300mm situation in a suction nozzle head width for example according to this in the zone of suction nozzle head.In addition preferably, this suction nozzle head is enlarging with regard to width on the direction of going towards operation wheel, and about this also additionally suggestion, the width of this nozzle body is about half corresponding to the suction nozzle head width in the zone of operation wheel or slidingsurface.And the width of this nozzle body is so selected in the zone of this operation wheel, promptly realizes a long and narrow generally version so that realize a suction in alcove especially.Verifiedly particularly advantageous about this be, the width of this nozzle body in the zone of operation wheel or slidingsurface roughly corresponding to the degree of depth of suction nozzle head maximum.Suggestion in one of technical solution of the present invention expansion design, this nozzle body extends between suction nozzle head and operation wheel or the slidingsurface in the bridging mode, and wherein height that herein should the bridging segmentation is roughly corresponding to the height of suction nozzle head.Also suggestion in addition, this bridging part is reserved half that bridging (a descending) free space and length that should bridging free space (observing) are greater than the suction nozzle head width on moving direction under the bottom side, according to this, just can guarantee this suction nozzle head desirable 360 ° or bigger deflection.And regulation, this tube connector can center on an axis tilt transverse to the suction nozzle traffic direction in first revolute joint.Based on this organization plan, this dust catcher that links to each other with suction nozzle by tube connector just can irrespectively be lain low generally with the inflection point of suction nozzle head to move forward with placing, so that for example aspirate the below of furniture.Also suggestion in addition, this tube connector also has one second revolute joint and has the axis of rotation that extension is departed from an axis from tube connector.Just provide the suction nozzle operability of improving generally, the especially travelling on turn direction by this second revolute joint.Have three different plane of rotations based on foregoing organization plan suction nozzle of the present invention.And regulation, this first revolute joint has the optimum position of a snap-lock, and wherein this snap-lock can not be eliminated by the gravity of suction nozzle.By upward deflecting around this operation wheel axis, this suction nozzle just can provide the position of lifting of a suction nozzle based on this organization plan, so that can intercept and capture bigger foul particle, if not these bulky grains will be pushed the front of amassing at suction nozzle.For the position of realizing that this dust catcher keeps flat generally, this this snap-lock of lifting the position can be eliminated according to wish.All aforementioned features not only have application value for the hardstand suction nozzle, and meaningful for the suction nozzle of carpet dust suction, are used to the situation of the bristle roller that rotates in case of necessity.Because formation one relative high negative in the zone at pump orifice in the time will aspirating suction nozzle and be applied in the carpet of particularly compact, so, the device that influences a suction air flow according to the inflection point of suction nozzle head is set in order to make suction nozzle head-deflection easier and advise.This suction air flow is so influenced herein, and the frictional force of promptly aspirating suction nozzle head below descends, even so that a deflection that also realizes the suction nozzle head in simple mode when the suction carpet is to go back to for cut-through thing and realization.Also in a preferred expansion scheme, stipulate that this suction air flow on an inflection point is less than the locational suction air flow a non-deflection about this.Stipulate that in an exemplary organization plan auxiliary air channel is opened on an inflection point.Herein in addition preferably, during ° angle that is from general operation (work) the position work of suction nozzle head during transverse to the deflection of operation (sailing row) direction, an auxiliary air channel is opened in deflection angle＞0 of suction nozzle head.Latter's (referring to auxiliary air channel) can be built into revolute joint the zone in or also can be in the zone of other member.In a deflection angle is that 0 ° (normal run location) do not have auxiliary air to flow into, and therefore at this moment whole pumping powers is available.This solution not only can be applicable under the passive type carpet nozzles situation but also can be applicable to have in the carpet nozzles of brush roller of rotation.Combination one motor in movable parts of suction nozzle (suction nozzle head) or fixed part (nozzle body) for this reason, it is directly for example by a transmission device or by a force transfer mechanism, for example tooth-like belt or the mechanism that is combined in the suction nozzle head drive one or more brush rollers.And can expect that this drive unit is realized by a turbine that is driven by air stream.The supply of here air-flow realizes that by pipeline these pipelines are introduced in the movable parts (suction nozzle head) by slip ring or other suitable element.For a inflection point at the suction nozzle head, a high suction force particularly is provided in its outside folding corner region, then in a favourable expansion structure scheme, advise that this suction air flow is being enhanced aspect one first folding corner region of suction nozzle head on an inflection point.Be deflected under the situation about moving on (travelling) direction, at the suction nozzle head like this in order to aspirate the volume flow that zone in front can utilize an increase effectively, so that can realize a for example darker swabbing action below furniture or in the alcove like this.In an expansion scheme, this effect so is enhanced, and promptly this suction air flow has been reduced at one second folding corner region of suction nozzle head on an inflection point.Another optimal way in this regard is, this suction air flow is to realize in the suction air flow aspect this second folding corner region by reducing in the enhancing aspect first folding corner region.According to this, just in this first folding corner region, that is be preferably in the suction nozzle head and be arranged in the front corner thereof zone along moving direction and realize a concentrated swabbing action.For example can stipulate that this suction channel is reduced according to described deflection angle towards the opening of second folding corner region, simultaneously, should but not be affected with respect to the opening of first folding corner region.The reducing of this suction channel opening to second folding corner region finally can cause leading to the sealing of the suction channel of this folding corner region.Therefore, whole pumping powers just are placed in first folding corner region.Stipulate that in a demonstrative structure scheme of technical solution of the present invention this suction channel is to realize corresponding to the cross section between the antetheca of end face arris and the vertical suction channel-wall segmentation at one of the suction nozzle head by reducing in the sealing aspect the folding corner region.This point can for example realize by change a vertical suction channel-wall segmentation in the process of suction nozzle head deflection, changes at this and just can realize under situation that this cross section that leads to the suction channel mouth of second folding corner region reduces.In another demonstrative structure scheme of technical solution of the present invention, stipulate, in the suction nozzle head, be provided with one with the partition wall of right angle extension and by reducing the sealing (degree) that this distance between a vertical suction channel-wall construction and this partition wall realizes this suction channel.Realize a gate principle according to this, one of them suction channel-end segment (part) that stretches in this suction nozzle head comprises one towards suction nozzle head direction part (zone) and open region of separating by the partition wall of this suction nozzle head for the sealing of semicircle plate-shaped.On normal operating position, that is be under the vertical directed situation, should allowed suction channel to be circulated by open region that partition wall separates by symmetry in the suction nozzle head direction that relatively moves.Under the state that the suction nozzle head is deflected, the subregion of this suction channel and the second end zone phase configuration by this partition wall and in addition preferably its diameter of bottom section by the suction nozzle head reduce or be closed, therefore in this first folding corner region, form an enhanced suction air stream.Advise in order to make the suction nozzle head be adapted to the ground unevenness that in addition this suction nozzle head circumference is movable transverse to the trip shaft of described vertical joint shaft orientation around at least one.About this preferred mode is in a configuration structure, this suction nozzle head is movable around the trip shaft of 90 ° of arrangements of mutual dislocation of two horizontal orientations, because the axle allocation plan of this universal type has just been realized the adaptability for ground to be cleaned of suction nozzle head the best.
