The specific embodiment
Fig. 1 is half sectional elevation according to the ventilation unit of first embodiment of the invention.
Ventilation unit comprises pipeline 10, and pipeline 10 has formed cavity between inlet opening 12 and exit opening 14.A part of inner surface 16 of pipeline 10 is spherical segments.
In the pipeline inside cavity, the main body 18 of shaping is at its spherical intake section 22 and be formed between the terminal functional unit 24 of its outlet and have slit 20 longitudinally.
The outer surface of an annular element 26 constitutes an identical spherical segment of spherical segment radius with pipeline 10 inner surfaces 16, and annular element can be along inner surface 16 slips.Annular element 26 comprises at least one arm 28, is preferably three, and is outstanding towards inside in the slit 20 of the main body that is shaped, and terminates in slot part 30 places of the main body 18 of shaping.This slot part extends longitudinally as shown in the figure, but it also can have different orientations, for example along spirality, this slot part has constituted the improved form of basic device, wherein basic device just has the arm 28 integrally formed with the main body that is shaped 18 simply, and the main body 18 of shaping does not have slit 20 yet.
In basic embodiment, the main body 18 of shaping can be simply around the center rotation of rotation combination, and wherein rotation forms in conjunction with the spherical segment by pipeline 10 and annular element 26.
In the improved form shown in Fig. 1, the main body 18 of shaping can also be along the longitudinal movement by the slip of arm 28 ends in slot part 30.Therefore this has just changed the shape of the passage of air stream between profiled body and pipeline wall, and has therefore changed flow rate.Therefore the part of the main body 18 that in fact is shaped may be very near the wall of pipeline 10, and therefore in fact the major part that flows is concentrated in an independent position on the periphery.Outside the regulatory function of main body 18 thereby flow rate, has big deflecting effect.
A previously described device preferably has three arms 28, but also may be the arm of arbitrary number.In addition, the end of arm can be simply to penetrate slit 20, and up to arriving a slot part, for example slot part 30, perhaps can have horizontal projection, makes the main body 18 that is shaped be connected with annular element 28, and slot part has shape as shown in Figure 2.In addition, annular element can dispose fin, is described with reference to Fig. 4 and Fig. 7 hereinafter.
When main body 18 operating members 24 that are shaped move, occupy a position, the main body 18 that in this position, is shaped along with annular element 26 with respect to pipeline 10 rotations, Fig. 6 show pipeline 10 at this moment and the main body 18 that is shaped between positioned opposite.Should be noted in the discussion above that at outlet 14 places and have only a passage that reduces between main body 18 and pipeline 10, although the major part of ventilation unit stream in the lower part by and upwards turned to, that is to say, functional unit 24 be moved towards a side.
In the embodiment of Fig. 1 and 2, be to realize profiled body is remained on the position with desirable orientation by the friction between annular element 26 and the pipeline 10 simply.It also may be necessary adopting a kind of more effective position holding device.Fig. 3 and 4 shows a kind of like this device.
In Fig. 3 and 4, by a kind of mechanism that produces the position confining force main body 18 of shaping is remained on the pipeline by annular element, this mechanism comprises a cavity 32 that is formed on the pipeline, be used to hold an elastomeric element 34, thin slice for example, described elastomeric element 34 has at least one projection 36, and projection 36 can cooperate with the surface elasticity ground of annular element 38.Annular element is connected with the main body 18 that is shaped by a plurality of arms 40.The outer surface of annular element 38 has rough zone 42, and when the parts that are shaped were moved into the position of hope, a projection 36 was maintained between two adjacent rough zones 42 at least.
Position holding mechanism obviously can be different.For example, annular element can be discontinuous at its periphery position, this discontinuous any type of elastic retraction means that comprises, and elastic retraction means produces a power and is used for annular element is pressed on the spherical surface of pipeline.
Therefore, in the variation of Fig. 8 and 9, annular element 58 has elastic tongue piece 52, and elastic tongue piece 52 is outstanding in the outside of annular element 58.When annular element 58 be molded with its arm 50 time, elastic tongue piece 52 is integrally formed with annular element 58.The outer surface of tongue piece 52 is used for sliding along the inner surface of pipeline 54.Therefore the value of the contact force between annular element and the pipeline being adjusted to hope by the size of decision tongue piece is possible.
In the variation of Figure 10 and 11, holding device comprises rough zone 62, and rough zone 62 has for example cross section of V font, is formed on the inner surface of pipeline 60 and has the elastically deformable end of the outer surface that nestles up annular element 56.Although rough zone 62 illustrates in the drawings is that they also can be any shapes of wanting, since main body centering in pipeline that they provide enough power to make shaping along the form of the line of the bus of pipeline.The position of rough zone can be opposite, that is to say, they can be positioned at the outer surface of annular element, and side opposite is smooth.
Fig. 4 and 7 shows a variation, when this variation tilts with respect to pipeline when the main body that is shaped, for example with position like the position class shown in Figure 6 in, strengthened the orientation that flows.
Fig. 7 is the end-view of the part of the annular element 38 in Fig. 3 and 4, should be noted in the discussion above that the inner surface of annular element and fin 46 are integrally formed.Fin 46 is comprised in the plane, and this plane comprises ventilate central symmetry axis.The inner end of fin 46 can be slided in the slit 48 of the main body that is shaped.Preferably, annular element has a plurality of fins, for example six.Fin have the main body that is shaped vertically on strengthen the function of flow orientation, thereby for example under situation shown in Figure 6, guided well at outlet 14 places by the stream that comes out by the wideest cross section that limits between pipeline 10 and the main body that is shaped.
As shown in fig. 1, the main body 18 of shaping may be slided the T of arm 28 shape terminal 31 by slot part 30 and is pushed to the inside of pipeline 10.This profiled body can occupy a position, and the inlet surface 22 of profiled body contacts with side opposite along inlet opening 12 in this position.In this position, flowing is interrupted in fact.Yet,, can strengthen described sealing by using the lip and the slot part that cooperate when this closure does not provide the sealing of expection.In the variation of Fig. 5, be formed on the lip 44 on the outer surface of main body 18 of shaping, when the main body 18 that is shaped was pushed into closing position, lip 44 was arranged in the slot part 46 of pipeline 10 inner surfaces.
Therefore, the ventilation unit that the present invention relates to allows the orientation of air stream, allows to adjust the flow rate of air stream simultaneously, and especially, has guaranteed the hermetically closing of ventilation unit, has therefore guaranteed the peace and quiet of ventilation unit.
The second embodiment of the present invention will here be introduced, and Figure 12 is the horizontal half sectional view according to the ventilation unit of this second embodiment.
Ventilation unit comprises pipeline 110, and pipeline 110 has formed cavity between inlet opening 112 and exit opening 114.The inner surface 16 of the part of pipeline 110 is spherical segments, and here corresponding central angle is about 90 degree among the embodiment of Tao Luning.
At pipe interior, the main body 118 of shaping defines a central passage 120, and the exit opening of this central passage has the grid 122 of functional unit 124 at the center.
The outer surface of annular element 126 constitutes the spherical segment that a spherical segment with the inner surface 116 of pipeline 110 has same radius, and annular element 126 can slide along inner surface 116.Annular element 126 comprises at least one arm 128, is preferably three, and arm 128 is given prominence to towards inside and stopped at slot part 130 places of the main body 118 that is shaped.Slot part shown in the figure prolongs along the longitudinal, but it also can have different orientations, and for example scroll is orientated, and constitutes a kind of modifying device of arm of main body 118 one that comprise simply and be shaped.
In this embodiment, the main body 118 of shaping can be simply around the center rotation of rotation combination, rotation occupies a position simultaneously as shown in figure 16 in conjunction with being that spherical segment by pipeline 110 and annular element 126 constitutes.
In the improved form shown in Figure 12, the main body 118 of shaping can also move along the longitudinal direction, therefore adjusts the shape of the passage of air stream between the wall of passage 118 that is shaped and pipeline.Therefore the part of the main body 118 that in fact is shaped may make the major part that periphery flows concentrate in fact on the position of periphery very near the wall of pipeline 110.Therefore in central passage 120, has significant deviation effect on the flowing of circulation.
A kind of device of having been introduced preferably has three arms 128, but also can be the arm of any number.In addition, the end of arm can be simply to enter slot part, for example 130, perhaps can have horizontal projection, and make the main body 118 that is shaped be connected with annular element 128.
In variation shown in Figure 16, annular element 126 has a plurality of fins 144, and each fin all is accommodated in the plane, and the plane has comprised the central symmetry axis of ventilation unit.The inside end of fin 144 can be slided in the slit 146 of the main body 118 that is shaped.Fin is disposed between the arm 140.Illustrate, ventilation unit may comprise two arms and four fins, perhaps three arms and three or six fins, and other number obviously also is possible.
The function of fin is to regulate the feasible mobile bus along the main body 118 that is shaped of flowing of air.By this way, be formed on pipeline 110 and the main body 118 that is shaped between air stream guided best, and provide the preferential orientation of exit air stream on a direction, the main body operating member 124 that is shaped on this direction tilts.
In the embodiment of Figure 12, the main body that is shaped is remained in position the friction of being passed through simply between annular element 126 and the pipeline 110 with the orientation of wanting realize.It also may be necessary using a more effective position holding device.Figure 14 and 15 shows a kind of like this device.Similar among ventilation unit first embodiment that device among Figure 14 and 15 and front were described, similarly parts use same Reference numeral, just add numeral " 1 " formation hundred figure places in front.
Position holding mechanism may be different obviously.For example, annular element may be discontinuous in its periphery, this discontinuous any type of elastic retraction means that comprises, and elastic retraction means produces a power and is used for annular element is pressed on the spherical surface of pipeline.
Introduce the 3rd embodiment of the present invention now.
In Figure 17, Reference numeral 210 expression pipelines, pipeline forms cavity between inlet terminal 212 and outlet terminal 214.Cavity limits an inner surface 216 between entrance and exit, and the part of inner surface 216 is spherical segments.The central angle of the spherical segment of inner surface 216 (218 places determine at the center) is at least 90 degree.
The main body 220 that is shaped is installed in pipeline 210 inside.The main body 220 that is shaped has arm 222, and arm 222 is side-prominent from exit opening.Arm 22 has functional unit 224 at outlet side, and in main body 220 inside that are shaped, cam 226 has guiding groove 228.
Two slide units 230, the shape of each parts all is the part of spheroid, has the angle of 90 degree in fact, is installed in pipeline 210 inside and contacts with pipeline 210.Each slide unit 230 has at least one arm 232, and arm 232 portion's end within it has a cam projection 234 and is used for moving at cam path 228.
In the position shown in Figure 17 top, the exit opening of pipeline 210 is closed by slide unit 230, between the slide unit 230 in fact the longitudinal axis position at pipeline 210 be in contact with one another, in each side of arm 222.From this position, when user's pull operation parts 224, cam 226 causes that slide unit rotates towards pipe interior, towards the enable possition shown in Figure 17 the latter half by its slot part 228.In this enable possition, entrance and exit opening 212 and 214 is discharged loosely.
Obviously, the user has the ability by slide unit 230 opening and closing exit openings, and slide unit 230 forms a baffle plate.Yet in all positions, particularly in the centre position, the user also has the ability that the exit opening 214 that is parallel to pipeline 210 comes move operation parts 224, therefore changes the direction that air stream is discharged.
This layout as shown in figure 19, wherein the main body 220 of Cheng Xinging is spent through about 25 with respect to pipeline 210 rotations.Should be noted in the discussion above that in the first half of Figure 19 the part 231 of slide unit 230 is outstanding at outlet 214 places of pipeline 210, and therefore participated in the skew of air flow top.
In addition, in the example that illustrates, when functional unit 224 was the parts of a transverse extension, the user can make its longitudinal axis rotation along pipeline, and therefore makes parts 230 in spherical pipeline slides within, is connected with the longitudinal axis of pipeline.
Although the shape that slide unit illustrates in the drawings is the part of spheroid, have at least 90 degree, this character is necessary on spheroid part this point only, described this part also will cover a circle through pivot.For example, the edge of slide unit 230 may be fan-shaped on one side identical with inlet opening 212, is still remained on the spherical segment inside of pipeline 210 by two slide units 230 to guarantee the main body that is shaped.
Especially, help producing the frictional force that is applied in fact between slide unit and pipeline 210 inner surfaces, frictional force is that the adjacent part by the spherical segment end produces, because the elasticity that is easy to regulate them when making slide unit.
Yet shown in Figure 20 and 21, in a variation, holding member comprises the rough zone 246 that is formed on pipeline 244 inner surfaces, and has the elastically deformable end that cooperates with the outer surface of slide unit 242.This configuration certainly is provided with on the contrary, and rough zone is formed on the slide unit, and nestles up side opposite.
