The present invention relates to a kind of as claim 1 pliable and tough suction hose as described in the preamble and a kind of dust catcher that has according to pliable and tough suction hose of the present invention.
The suction hose that is used for dust catcher is made by expressing technique according to prior art.Produce the long element of a flute profile at this, and then spirality ground twines, produce thus one have spirality around the suction hose of fold (Balgwelle).This suction hose is given required pliability of flexible pipe and robustness simultaneously with slight weight.The member of this flute profile has a plurality of folds that extend in parallel.Especially there is the defective of birdie noise under the situation for the high throughflow speed of present suction air in this pliable and tough flexible pipe.Also precipitate dirt in the mode of not expecting in the fold of flexible pipe inside, this is a kind of allergy and health concerns.
By the known a kind of suction hose of EP 1 099 894 B1, wherein in order to overcome the birdie noise when the through-flow air and in order to improve flow passage resistance, suggestion is positioned at the lug boss on the flexible pipe medial surface and the special geometry of depressed part.Especially the special ratios between the size on the flow direction is considered to be favourable in size on the flow direction and depressed part with lug boss at this.But defective is that the structure of describing in EP1 099 894 B1 is complicated, and can not avoid the dirt deposition.
The objective of the invention is, overcome the defective of prior art, and the pliable and tough suction hose that a kind of through-flow characteristic with improvement especially is provided is for using.
This purpose is achieved by the feature of independent claims.
Favourable structure of the present invention and improvement project are to provide in the dependent claims.
The present invention so improves this type of device, and the member at least one plane of extending substantially on flow direction and in a circumferential direction promptly is set on the flexible pipe medial surface, and this member covers depressed part at least in part.The member on the plane of She Zhiing has reduced the distinctive flow passage resistance of suction hose like this.When suction hose was through-flow, preventing to become a mandarin entered depressed part.Prevent thus perpendicular to flowing that preferred direction of flow is expanded, and carry the air stream of laminar flow.By reducing the tendency that forms turbulent flow, obviously reduced flow passage resistance.By covering depressed part at least in part, reduced dust or the analog deposition in depressed part effectively simultaneously.By arranging the member on this plane, can only keep at present based on the processing technology of extruding substantially in addition with inappreciable variation.Only increase the flexible pipe deadweight in addition slightly, and keep substantially that it is pliable and tough.Particularly advantageous at this is that the member on described plane covers depressed part fully, especially under the especially little situation of the bending radius of suction hose.
Particularly preferred embodiment regulation, the member on the plane of extending on circumferencial direction and flow direction overlaps on flow direction at least in part.By the member of such plane of arrangement, promptly member provides the almost surface of sealing originally in flow direction top overlap joint to give in flow air on the flow direction on the flexible pipe medial surface.Replace original because muscle shape structure and the air stream of eddy flow can produce flowing of laminar flow basically now.Especially can stipulate that at this described overlap joint carries out so far,, also can realize enough overlap joints, and realize the air guiding that improves thus even make hour in the bending radius of suction hose.
A preferred embodiment of the present invention is, is provided with a plurality of members on the circumferencial direction and the plane of extending on flow direction.The member on a plurality of planes is especially worked as processing technology and is comprised when twining out the bathtub construction with a plurality of folds arranging on the flexible pipe medial surface it is preferred in existing processing technology scope.
Preferably make a plurality of therewith relatively at circumferencial direction with at the member on the plane of extending on flow direction overlap joint mutually on flow direction at least in part.Turbulent flow tendency and the through-flow advantage of base layer stream that same thus realization is littler.
Same particularly preferred embodiment is, the member on the circumferencial direction and the plane of extending on flow direction forms an inner hose.The member on plane forms continuous inner hose, makes the flow passage resistance of suction hose at least almost reduce to smooth flexible pipe.In this way, further reduce because the turbulent flow that the geometry of flexible pipe causes.Further reduce the deposition of the dirt particle of guiding and formation smell or bacterium that may be relevant therewith along with air.This point also is favourable during near use suction hose irritated personnel.This continuous inner hose preferably is arranged in the procedure of processing of following the suction hose process.
Particularly advantageous is that at least one electric lead is arranged between suction hose and the inner hose.Cable solution (Incord-Loesung) can realize on the one hand on the processing technology favourablely and in the structure of flexible pipe internal protection electric lead in this, and the advantage of smooth suction hose inner surface is provided on fluid technique simultaneously.
Another favourable embodiment is, is different at the material of the circumferencial direction and the member on the plane of extending on flow direction with the suction hose material.Select different materials for suction hose with the member that is arranged on plane wherein, mean another free degree aspect the inner flow passage resistance of optimization suction hose.At this material that can select the member on plane like this, make the member on plane have characteristic favourable on fluid technique.Pliability and the robustness that simultaneously can regulate suction hose itself independently.
Especially can stipulate at this, more pliable and tougher at the material of the member on the circumferencial direction and the plane of on flow direction, extending than the material of suction hose.If the member on plane constitutes than suction hose itself more pliable and toughlyer, then can make the member on plane adapt to flow direction when externally suction hose bends and cover depressed part.In addition the slight modification of the member on the plane of Cun Zaiing the pliability of suction hose.
The invention still further relates to a kind of dust catcher that has as each described pliable and tough suction hose in the above-mentioned claim.
The present invention is based on such understanding: around on the lug boss of the fold of suction hose, covered the then pliable and tough squamous sheet (Schuppe) of the depressed part of this lug boss, perhaps, obviously reduced the flow passage resistance of suction hose in the thin pliable and tough inner hose of the suction hose inside of being furnished with fold.This suction hose is easy to process in the scope of existing processing technology, and it has the through-flow characteristic of improvement.
By means of embodiment the present invention is described exemplarily below with reference to accompanying drawing.In the accompanying drawing:
Fig. 1 illustrates the cross-sectional view according to the first embodiment of the present invention,
Fig. 2 illustrates the cross-sectional view according to the second embodiment of the present invention.
Fig. 1 illustrates the cross-sectional view according to the first embodiment of the present invention.With schematic diagram an intercept 10 that is used for the suction hose of dust catcher is shown at this.This suction hose is made by continuous expressing technique.The wall body 10 of this suction hose have spirality around fold 14.They are looked from the inner space 16 of suction hose section 10 and are divided into depressed part 18 and lug boss 20.On lug boss 20, be mounted with squamous sheet 22.They extend to next lug boss 20 since a lug boss 20 always on flow direction 24.The material of this squamous sheet 22 is compared softer with the material of wall body 12.This squamous sheet 22 is extruded in the process of outer wall 12.About shown in dimension scale be noted that and only relate to schematic diagram here that it can the presentation function principle.
The function of the squamous that is in operation sheet 22 is as described below: pass through 22 guidings of squamous sheet substantially along flow direction 24 flow air.Because squamous sheet 22 from a lug boss cover next on fluid technique disadvantageous undercut portions, promptly cover depressed part 18, air stream is through-flow on the principal direction 24 given by squamous sheet 22 substantially.Suppressed to form other common turbulent flow.Air is guided by laminar flow ground and is avoided because the turbulent flow that depressed part 18 produces.The advantage of the simultaneously existing suction hose of making by expressing technique is kept, and for example keeps highly flexible when keeping robustness.Settle 22 deadweights that increase suction hose slightly of squamous sheet.The flexibility of squamous sheet 22 or activity can be by its geometries and by selecting material irrespectively to adjust with wall body 12 characteristics of suction hose within the specific limits.According to employed through flow velocity, the geometry of scale is mated.Can squamous sheet 22 be shortened by fluid technique modeling squamous sheet equally.Other advantage of the present invention is to reduce the accumulation of dirt in depressed part 18.Additionally can pass through the uncomfortable noise of the mobile minimizing of air of upper stream to a great extent.
Fig. 2 illustrates the cross-sectional view according to the second embodiment of the present invention.The intercept 10 of suction hose that is used for dust catcher is consistent with the described embodiment of Fig. 1 aspect its outer shape.It has an outer wall 12 of making by expressing technique equally, it have spirality ground around fold 14.They are looked from suction hose inside 16 equally and are divided into depressed part 18 and lug boss 20.Replacement is placed in the squamous sheet 22 on the lug boss 20 in Fig. 1, add second a continuous inner hose 30 in this embodiment.This inner hose or can extrude with corresponding internal diameter perhaps imports as the less flexible pipe that is inflated.This inner hose 30 is thin pliable and tough sleeve pipes of being made by a kind of material, and this material is different with the material of outer wall 12 to be selected with hydraulically operated consideration.
In a second embodiment, only guide along the air of flow direction 24 by inner hose 30.Therefore it has almost desirable shape of cross section, and it is compared with common flexible pipe has more small flow passage resistance.The advantage of first embodiment here also is suitable for, because the inwall of sealing has suppressed the dirt deposition better and formed uncomfortable additional noise.As additional advantage, the hollow space that forms between the inner surface of the outer wall 12 of the outer wall of inner hose 30 and suction hose intercept 10 for example can be used to settle electric lead or analog.By external hose 10 and inner hose 30 are separated fully, can select two kinds of materials relatively independently.Keep simultaneously the process of external hose 10 steadily, the adding of inner hose 30 then is an additional processing step.By suitably selecting geometry and material, can realize also that generally material still less uses.
Disclosed feature of the present invention not only can be individually but also arbitrarily in combination for realizing that the present invention is important in superincumbent description, accompanying drawing and the claim.
