Description
Technical field
The present invention relates to a kind of filter bag with gripper shoe, wherein, at least a portion zone of this filter bag abuts on the gripper shoe under the state that does not load.
Background technology
The filter bag of described type is known, and especially is applied on the dust catcher, further especially is applied on family expenses-dust catcher, is used for filtering when dust catcher is worked the suction air that contains dust and foul.Under the state that does not load, that is to say at filter bag not load under the state of suction air, can be especially according to the degree of filling of filter bag its subregion be so abutted on the gripper shoe, that is, gripper shoe to enter discharge orifice local at least covered.This situation insert one without use and also have at least part of folding new bag after also can exist.This can cause the device that holds this filter bag, and for example dust catcher work when starting operation is not normal.
Disclose a kind of filter bag by EP1787561A1, wherein below gripper shoe, set a locking device for the entrance in the filter bag.This locking device can move to deployed position from detent position, and wherein, described transfer is forced to produce when inserting filter bag.At this, can act on the locking device by means of the bag zone that is not connected with locking device.
Summary of the invention
Consider known prior art, technical problem to be solved by this invention is the filter bag of the described type of a kind of more reliable performance of structure.
This technical problem solves by a kind of filter bag with gripper shoe, wherein, the subregion is used for manually-operated lever segment with moulding and is connected, for strutting described filter bag under the state of having put into the filter bag chamber at described filter bag, the described subregion of while forced synchronism.Can manually strut filter bag in filter bag chamber outside by means of lever segment.Lever segment since with being connected of the respective segments of filter bag, force these Partial synchronizations with filter bag to strutting the position.The subregion of filter bag can be separated by with gripper shoe at least in this wise by set lever segment,, guarantees normally operation that is.The subregion moves to such position at least by lever segment, so that device, especially the dust catcher that is equipped with filter bag can normally move in this position, wherein, the subregion can further be heaved by the air stream that acts on the filter bag when moving after moving by lever segment fully.In any case, by the movement by means of lever segment, got rid of the filter bag subregion and when operation, be in the position that hinders initial inflow.Lever segment can be take the simplest structural design as manually-operated, so that the user especially can strut the subregion of filter bag easily before first filter bag being inserted the filter bag chamber.Difference also or therewith combination therewith, the subregion also can be designed like this, that is, so that especially the filter bag subregion can strut automatically, for example can insert chamber explicitly with filter bag, realize this point by in chamber or the direct suitable construction measure in filter bag.
It is especially favourable to such filter bag that the solution of advising is proved to be, that is, the hole on the gripper shoe of this filter bag is closed by a lid under the state that does not load.Provide the space of opening usefulness in running status to lid by the subregion that especially struts filter bag, and when not strutted in the subregion, because the subregion lies in the face of covering, can not or can not guarantee at least that normal operation ground realizes the upset of lid.
Be designed in a kind of expansion design of theme of the present invention, described lever segment is hinged on the described gripper shoe.Therefore, set clear and definite axis of rotation for lever segment.In addition, according to this design, lever segment can not be connected with the gripper shoe of filter bag with breaking away from.In addition, lever segment can be hinged on the gripper shoe in this wise, that is, insert in the process of filter bag chamber to move by lever at filter bag and realize forcing to strut.In addition, lever segment can be used as parts separately and is hingedly fixed on the gripper shoe by common, for example uses a common articulated structure.In addition, also have such possibility, especially in the gripper shoe of making as plastic injection piece, lever segment and gripper shoe are one-body molded with material ground, and described hinged for example by material attenuation formation film hinge.Hinge area between lever segment and the gripper shoe also can be passed through the second when being designed to plastic injection piece, especially soft plastic components forms.
In preferred design, in the cross-sectional view of gripper shoe, see, described lever segment can turn round 10 degree or larger angles together with the subregion of filter bag, such angle for example, this angle is so that subregion and gripper shoe, further and have enough intervals on the gripper shoe between the presumable closing cap.Further strutting that the subregion is possible can be fully by flowing into the air stream realization of supporting plate hole, and this air stream is heaved filter bag.By means of strutting that lever segment is realized, can vividly describe as for strutting whole filter bag " initial igniting ", at this moment, hole on the gripper shoe is towards rear side, namely side direction goes out close to open at least in the filter bag, and dodges out towards the rotating space of open position for the seal cover that is provided with in case of necessity.
Regulation in another of theme of the present invention preferably designs, lever segment struts ground, position by pre-tensioner towards it.According to this configuration, automatically strut and to realize by lever segment.Thus, although also nonessential, can abandon the structural measure that in the filter bag chamber, is provided for strutting lever segment and struts filter bag-subregion by this lever segment.Therefore, whole device for spreading is the part of filter bag.Because, this filter bag is typically designed to disposable use, that is to say the new filter bag that after filling fully, will be replaced with without using, so the pretension of lever segment can design in this wise, namely, this pre-tensioner direct action that only rises in case of necessity that is to say when filter bag is put into the filter bag chamber under not used state and work for the first time.Correspondingly, pre-tensioning can be adjusted setting like this, that is, can be thus so that lever segment only turns round for example 10 to 20 degree, and impel filter bag-subregion from abutting in position movement on the gripper shoe away from the position of gripper shoe.For pretension, a spring that acts on is set between gripper shoe and lever segment.This spring for example can be selected and only is made of hinge for the structural design of join domain between lever segment and the gripper shoe by corresponding material, for example, further consists of by lever segment and the gripper shoe integrated injection molding when the softened state.Alternatively, a traditional spring can be set also, disk spring for example, the one end for example works to gripper shoe, and the other end then loads lever segment towards strutting ground, position.Spring force preferably is adjusted into, one side but then again should be so little even as big as strutting lever segment and filter bag subregion, namely, so that under the folded state of filter bag, can realize the stacking of a plurality of this bags, can not cause again lever segment to rotate simultaneously.
Lever segment is preferably especially at initial position, that is to say the position that is not strutting, see in the direction transverse to its gyroaxis, extend past the subregion of gripper shoe, and this lever segment correspondingly almost is parallel to gripper shoe or becomes one for example less than 10 acute angles of spending with gripper shoe at initial position.This is proved to be is favourable at the height that does not have that use, folding filter bag especially.Therefore, can preserve the filter bag of a plurality of designs like this stackingly.
For strutting filter bag-subregion, lever segment can be connected with filter bag-subregion, for example with its welding or bonding, realizes thus the forced synchronism of subregion.Stipulate in a kind of preferred design of theme of the present invention, lever segment is designed to have the camber member of bow-shaped arm.Yet, also can be a kind of plate-shaped member, also can be a kind of shaft-like parts in addition.Be in the design of camber member at lever segment, bow-shaped arm arranges mutually along gyroaxis with being separated by.At this, the arm of camber member further can be to cause the spring element that struts simultaneously.
In addition, be different from bonding or welding between lever segment and subregion, the subregion also can be configured to the sleeve part, and lever segment embeds described sleeve part, and for example the arm of camber member embeds described sleeve part when lever segment is designed to camber member.At this, the sleeve part for example is shaped to bag-shaped, and wherein, lever segment partly inserts described sleeve part fully or only, and further alternative is to insert a plurality of sleeve parts that are successively set on the longitudinal extension of bow-shaped arm or lever segment.
The design code that another is favourable, that is, lever segment relatively gripper shoe kayser struts the position at it.This structure can occur with the elastic tension of aforementioned lever segment, yet, also can not use this structure.At this, the strutting the position and can get involved manual realization by the user of kayser, perhaps alternatively, further also can be therewith in combination by in the process of the filter bag chamber of packing at filter bag by force shift lever partly realize.Described kayser is in preferred design, and in gripper shoe was articulated and connected zone on lever segment, for example the cam by a lever side was absorbed in the groove of a gripper shoe side and realizes.
Can stipulate at last, lever segment relatively the gripper shoe kayser in its folding position.This kayser also can advantageously be realized in hinge area.According to this configuration, lever segment is under the state that filter bag does not load, and especially kayser is fixed on the position that almost is parallel to gripper shoe under the state that does not have use, and the subregion of filter bag abuts in the inboard of gripper shoe in this position.This is conducive to the structure height of filter bag under folding state.Kayser is fixing only can be cancelled according to wish, especially get involved by the user, in case of necessity also by in the dust catcher, the further structural measure in the zone of filter bag chamber can realize the pressure control of lever segment thus when cancellation struts the kayser of position in addition.

The specific embodiment
At first explain with reference to Fig. 1 and explanation dust catcher 1, especially be designed to the family expenses-dust catcher with the handle device of manual guidance.This hand-held device at first has a basic device 2, and with motor one unshowned, that be used for suction/blasting unit.Be provided with one at basic device 2 and be designed for the filter bag chamber 3 that holds the dust thing that drinks up.This chamber comprises a filter bag 4.
Power for the motor that is integrated in the basic device 2 by cable 5.
In addition, basic device 2 has a gooseneck shape thrust, and this thrust extends past the zone of filter bag chamber 3.This thrust forms a socket that is used for the handle 6 of dust catcher 1 in free-ended zone.In the free-ended zone of handle 6, be provided with control handle 7.This control handle have an available thumb manipulation, form is the control module of slide switch, can regulate the power that is contained in the motor in the basic device 2 by this control module.
For processing the floor, basic device 2 is connected with attachment device 8 according to flowing.This attachment device can be one to have the suction nozzle of the brush of rotation.
The suction nozzle that attachment device 8 does not illustrate according to flow be contained in filter bag chamber 3 in filter bag 4 be connected, for this reason, a not shown flow channel passes basic device 2.This flow channel divides at the distolateral a junction that becomes.
The coupling part is arranged in a boxlike bearing, among the interface T of this boxlike susceptor design between filter bag chamber 3 and basic device 2.Be extended with the gripper shoe 9 of that made by plastic material in the embodiment shown a, filter bag 4 with this interface, this gripper shoe has a through hole 10 that is used for introducing the suction air that contains dust with staggering, and this through hole is configured in the coupling part of suction channel.In the bottom side of gripper shoe 9, namely the housing region place of basic device side is fixed with a ventilative dust bag 12 dorsad.Filter bag 4 when work the position in filter bag chamber 3, be in inversion state (
), when suction operation, flow into from bottom to top air via through hole 10 thus.
When not moving, that is to say when filter bag 4 does not load the suction air, the through hole 10 of gripper shoe 9 is facing tegmentum 11 coverings of the inboard place of bag.Described lid is hinged on the bottom side of gripper shoe 9.The loading that move through air of lid 11 on the direction of hole realizes.Resetting of lid realizes by the spring support.This structure so that filter bag 4 can when inversion state, move.
Through hole 10 correspondingly covers 11 in addition, is not designed to circle on profile, but the ligule of approximate longitudinal extension.Hinge axes x stretches transverse to lid 11 longitudinal extension, further also transverse to the longitudinal extension of gripper shoe 9.The hinge that forms hinge axes x preferably forms film hinge (Filmscharnier) by corresponding material attenuation.
Based on the inverted arrangement of filter bag in dust catcher 1 or filter bag chamber, in loading condition not, namely when dust catcher 1 does not move, especially when filter bag 4 does not have or a little dust thing only is housed, in addition, especially under the new state of not using, filter bag 4 is in by the state shown in Fig. 2 and 3.As especially by the cutaway view among Fig. 3 as can be known, under this state that does not load, almost reclining gripper shoe 9 of the subregion 13 of dust bag 12 is extended or is extended tinily with the gripper shoe spacing, and this can hinder when dust catcher 1 operation and cover 11 the motion of opening.To cover 11 and do not open with can having obstacle in order to make, this subregion 13 of dust bag 12 was strutted before filter bag 4 work.
For this reason, be provided with lever segment 14, this lever segment struts the position being carried in by the first form of implementation medi-spring shown in Fig. 1 to 5 with supporting.
The lever segment 14 of the first form of implementation is configured to camber member 15, and it has the bow-shaped arm 16 that is parallel to each other and extends.The end of bow-shaped arm 16 is fixed on the gripper shoe 9 by hinge arrangement 17, and this hinge arrangement is positioned at gripper shoe 9 transverse to the longitudinal edge zone of the gyroaxis x extension of lid 11.Correspondingly, the hinge axes y of consequent lever segment 14 stretches transverse to the hinge axes x of lid 11.
When gripper shoe 9 and camber member 15 during with material ground Integral design, hinge arrangement 17 realizes by the material attenuation in the first form of implementation, wherein, and further preferably with plastic injection-moulded technique manufacturing.At this, gripper shoe 9 and camber member 15 are to make like this,, almost realize that perpendicular to the position on gripper shoe plane the inclination of camber member 15 struts (Aufstellneigung) by hinge arrangement 17 one that is.Correspondingly, hinge arrangement 17 forms a spring 18, and this spring keeps one to strut elastic force in the position that changes over to of camber member shown in Figure 3 15.The free end of lever segment 14 or camber member 15 inserts a specially designed bag-shaped sleeve part 19, and this sleeve partly is positioned at the wall outside of dust bag 12, especially is positioned at subregion 13.The subregion 13 of lever segment 14 and dust bag 12 is used for declaratives zone 13 at non-loaded or the not position under the loading condition, for example state when the user takes out a new filter bag 4 from storage box or analog in position shown in Figure 3.The elastic force of hinge arrangement 17 shown in the position be released.Accompanying drawing correspondingly shows elastic force and discharges centre position afterwards.But elastic force also can for example arbitrarily discharge at the kayser that changes the position over to by lever segment 14, and this kayser for example can be cancelled when filter bag 4 is put into chamber 3.Therefore, for example can further lever segment 14 be configured to rocking bar, it has a swing arm, the release projection in this swing arm and the chamber 3 or analog mating reaction.Do not have spring to load and can consider this scheme yet.
Load according to the spring in, the hinge arrangement 17 preferred at this, lever segment 14 when removing the load that suppresses lever segment 14 (for example since other keeps flat in storage box or the analog, and folding filter bag 4) automatically get back to the described position that struts of Figure 4 and 5, link in this subregion 13 with dust bag.Afterwards, form enough spaces in the bottom side of bag inner support panels 9, be used for when dust catcher moves, strutting without barrier covering 11.The strutting the position and can limit with backstop of lever segment 14.In the most simple design, the motion that struts of lever segment 14 only determines by elastic force, and this elastic force not further turns round this lever segment after lever segment 14 arrives certain distraction angle.
In addition, as shown in Figure 10, lever segment 14 also can only form by a camber member 15 that is formed by spring steel wire alternatively, and this spring steel wire is supported on the bottom side of gripper shoe 9 with its free end 20, and therefore, camber member 15 forms spring 18 simultaneously.
Fig. 6 to 9 shows another kind of form of implementation.At this, lever segment 14 also is designed to arciform, and is that form is the steel wire of arciform structure, and this steel wire embeds the admittance projection 21 of gripper shoe side on the distolateral formation axis ground of bow-shaped arm 16.The end section 22 of bow-shaped arm 16 is passed and is admitted projection 21, for this reason, admits projection to have in the axial hole of revolution.The end section 22 of bow-shaped arm 16 is from inside to outside passed, and wherein, the free end 23 of end section 22 bends perpendicular to axis of rotation y in the outside.These free ends 23 lie in its towards each admit on the surface 24 of projection 21.Rotary path at these free ends 23 is provided with 24 projections 25 of giving prominence to from the surface.
At initial position, namely be equivalent to the folding position of filter bag shown in Figure 6, the free end 23 of camber member 25 abuts on the side of projection 25 separately in a side.Correspondingly, camber member 15 or lever segment 14 and thus described dust bag-subregion 13 be fixed on initial position by kayser.For subregion 13 is strutted to run location, be necessary the operation by the user, but also can by the structural measure in filter bag chamber 3 zones, the free end 23 of camber member 15 emerged above described projection 25 in case of necessity.Correspondingly, this point is only gone by wish.Afterwards, lever segment 14 and subregion 13 have been obtained by the position that struts shown in Fig. 7 and 9.
