The specific embodiment

Fig. 1-3 and 7-9 show one and are combined with the actuator 12 that is used at the device 14 of fluid inducing turbulence, and Fig. 4-6 shows and is used for forming a core rod 15 that passes the fluid passage of device 14.With reference to Fig. 2, fluid passage 17 comprises a first passage part 20 that runs through wherein, and this first passage part 20 is extended between first passage end 23 and second channel end 26.Channel part 20 is divided into subdivision 20a and 20b at transitional region 20c place.Although can't see in Fig. 2 and 3, the total length that each passage subdivision 20a and 20b all run through them has tapering.Preferably, although also nonessential like this, each this tapering is all consistent basically on the length of subdivision 20a, 20b, and promptly described tapering is linear.In addition, as hereinafter will more describing in detail, the transverse cross-sectional size that described tapering causes subdivision 20a, 20b along from first end 23 to the second end 26 direction dwindle.Channel part 20 is tapered more to be shown clearly in Fig. 4 A and 4B, and they show core rod 15 and narrow down from end 15a to end 15b.Core rod 15 can be tapered in any suitable manner.But, provide the non-restrictive example of cone angle A, the B, C, D and the E that are used for core rod 15 to be similar to taper value below in the table 1.One or more surf zone of core rod 15 can be not tapered.For example, the surperficial 28a of core rod 15 (Fig. 4 B) can be not tapered, and tapered with its opposite surfaces 28b.Channel part 20 from the end 23 to the end 26 narrow down and increased the flow velocity that flows through material wherein, this will help the mixing of material.A plurality of biasing ribs 29 extend partly in the channel part 20, and a sinuous turbulent flow path that is used to flow through the material of channel part 20 is provided thus.An additional channels part or a mixing chamber 30 that is communicated with channel part 20 can be set.Mixing chamber 30 can partly be limited by inclined surface 31, can improve the turbulent flow in the mixing chamber 30 like this.

For the aerosol container 36 of material, actuator 12 can comprise a top cap 33 (Figure 1A).Described material can be any one in the various materials, such as air freshener, insect-controlling agent, coating, hair jelly, cleaning agent, polishing agent, aromatic or be stored in other material in the container.A kind of typical material can comprise a kind of suitable aerosol formulations, and it can comprise the solution of any routine or unconventional latex, suspension or active component.Described material can or cannot utilize suitable propellant to remain under pressure in the main body 37 of container 36.Suitable propellant can comprise hydrocarbon propellant or other compressible propellant, and such as the so incompressible propellant of carbon dioxide.By by the button 33a on the cap that bears down on one, tilt thus or press down valve rod 38 (depending on the design of valve rod 38) to open a valve (not shown) that is arranged at container body 37 inside, make material from valve rod 38 ejections.Alternatively, as shown in Figure 1B, actuator 12 can comprise a sprinkling button 43 on the valve rod 38 that is assemblied in container 36.Under any circumstance, actuator 12 all can be made by any suitable material, such as plastics.Actuator 12 can be designed to not comprise valve rod 38 and the container that comprises inner concave shape receiving valve (but it is not shown well known in the art).In this case, actuator 12 will carry a suitable intubate, and this intubate engages with described inner concave shape receiving valve to actuator 12 supplies with material.

Referring again to Fig. 2 and 3, subdivision 20a has formed a socket 45 that is positioned at 23 places, first passage end, wherein these socket 45 receive valve stem 38.Socket 45 comprises a conical butt conical surface 46, and it helps valve rod 38 is inserted in the socket 45. Channel part 20 and 30 extends along first direction, and second channel part 47 is extended from channel part 20 along second direction.As shown in the figure, second channel part 47 is substantially perpendicular to first passage part 20.But channel part 47 can extend from channel part 20 with channel part 20 conllinear or with arbitrarily angled.Thus, described angle can change according to the type of material.For some material (such as cleaning agent), may wish to spray along a direction of crossing valve rod 38 basically, and for other material (such as air freshener), may wish to spray with the direction of valve rod 38 conllinear basically, so that material upwards is sprayed in the air along one.Second channel part 47 ends at a tap 51, and material finally distributes or is sprayed to the surrounding environment from this tap 51.

It should be noted that second channel part 47 can save, and first passage part 20 can be provided with a suitable tap (not shown).Also must be noted that and replace channel part 20 or except channel part 20, second channel part 47 can be provided with rib 29.Replace channel part 20 or except channel part 20, second channel part 47 also can be tapered.To need to use a kind of be similar to or the core rod identical with core rod 15 forms channel part 47 like this.But; for some material type; make that second channel part 47 is tapered so that it will be undesirable (depending on required sprinkling pattern) that channel part 47 is increased towards tap 51 sizes, produce than required particle or big particle or the drop of drop because this taper might exceedingly reduce flow velocity.

The sprinkling pattern that obtains a kind of the best by formation turbulent flow in first passage part 20 is an astonishing and unpredictable result, because along with material flow is crossed second channel part 47 and finally flowed out tap 51, the sprinkling the pattern whether turbulent flow in the channel part 20 keeps material to be in a kind of the best is uncertain.

Fig. 4-6 shows the recess 60 of a plurality of formation ribs 29.Core rod 15 comprises a conical region 61, and it narrows down from end 15a to end 15b.Fig. 4 A shows conical region 61 and has a longitudinal size L and a lateral dimension T.Recess 60 is between end 15a, 15b.Recess 60 is biased along described longitudinal size.Recess 60 also is biased along described lateral dimension, and more specifically says, recess 60 is illustrated on the opposite sides that is positioned at core rod 15.Therefore, rib 29 is biased along the longitudinal size and the lateral dimension of channel part 20.Recess 60 is alternately staggered on the opposite sides of core rod 15, thereby makes rib 29 alternately staggered on the opposite sides of channel part 20.Recess 60 can have any suitable dimensions.For example, as shown in the table 1 of Fig. 5 A and back, recess 60 can have the depth dimensions F that approximates 0.21 millimeter greatly and approximate 0.51 millimeter length dimension G greatly.The material that flows through channel part 20 can flow around rib 29 in the zigzag mode.The material that flows around rib 29 preferably at least twice skidding from first passage part 20 advances or zigzag marches to an other side, and preferably above twice.Any active component that is contained in the material all utilizes turbulent flow to mix, and a kind of mixture of homogeneous basically is provided best, and wherein drop or particle have the size of enough unanimities.Best, the volume of material that leaves tap 51 is even basically, has the regional area minimum of variable grain concentration and/or particle size simultaneously.Distribute in view of waste and with the poor efficiency that material is dispensed in the surrounding environment, the excessive humidity of perhaps spraying volume is so the concentration of local zone can be a shortcoming.

The cross section of channel part 20 can be rounded or non-circular.Preferably, the cross section of channel part 20 is rectangular basically.Therefore, core rod 15 is rectangular shaped substantially, has opposed narrow sidewall 65 (Fig. 4) and opposed broad side walls 66 (Fig. 5).Thus, believe that the rectangular shape of channel part 20 is allowed this channel part 20 along with core rod 15 than square passageway deflection takes place more from wherein taking out, thereby help core rod 15 is removed from fluid passage 17.The tapered profiles of core rod 15 also helps after molding process core rod 15 being taken out from fluid passage 17.Consider that core rod 15 can be along with taking out this core rod 15 and repulsion rib 29 from channel part 20, described tapered profiles is especially useful.As shown in Figure 5A and 5B, each recess 60 all limits a depressed part 73 that has tapered edge 76 and sharp edges 78.Tapered edge 76 is positioned at the upper end (as can be seen from Fig. 4) of each recess 60, and this helps core rod 15 is taken out from fluid passage 17.Depressed part 73 can comprise any suitable radius of curvature R, such as being 0.1 millimeter.Each edge 76,78 all has one and approximates 0 radius of curvature basically greatly.But edge 76 or 78 can comprise one greater than 0 radius of curvature.Especially with reference to Fig. 5 B, recess 60 can be with any suitable spaced apart apart from Z, and preferably, Z is approximately 1.52 millimeters.Recess 60 can be spaced apart with any suitable distance with the longitudinal centre line C of core rod 15, such as at the distance shown in the table 1 of back or size AC, AD, AE, AF, AG, AH and AI.Referring again to Fig. 5 A, tapered edge 76 is partly limited by recessed surfaces 79, and this recessed surfaces 79 and a horizontal axis 80 that passes edge 76 limit an angle I.Angle I can fall within any suitable number range, but preferably is approximately 60.22 degree.Recessed surfaces 81 and a horizontal axis 82 that passes edge 78 limit an angle H.Angle H can approximate 13 degree greatly.With reference to Fig. 6 C, core rod 15 also comprises an inclined surface 83, and this inclined surface 83 has formed the inclined surface 31 of mixing chamber 30.Inclined surface 83 can limit an angle X who is approximately 30 degree with respect to a horizontal axis 85, and axis 85 passes longitudinal centre line C at 86 places, tip of core rod 15.Selectively, angle X can be 28.47 degree.The tapered edge 76 of described tapered profiles and recess 60 is allowed core rod 15 taking-ups, otherwise may be difficult or core rod 15 can't be taken out, and avoided thus as an extra number of assembling steps need with one independently the turbulent flow member insert in the channel part 20,47.Just as well known in the field in this technique, because second channel part 47 branches off from first passage part 20 with an angle, so using a plurality of core rods and take out these core rods along different directions can be very complicated, why Here it is usually uses the turbulent flow plug-in unit to come the reason of the mold component of replace complex in existing apparatus.Although the present invention has avoided use turbulent flow plug-in unit, people still can optionally be provided with plug-in unit in channel part 20,30,47.

With reference to Fig. 6 D, core rod 15 comprises the conical region 90 and the cylindrical region 93 that cross section is rounded that form conical butt conical surface 46, and this cylindrical region 93 has formed one across column sealed regional 97 (Fig. 2,3) between the point 98,99 of passage 17.Sealing area 97 is rounded, thereby makes sealing zone 97 seal circular valve rod 38 in the close mode of effective liquid, and channel part 20 is rectangular basically simultaneously, helps best core rod 15 is taken out.Cylindrical region 93 can be tapered.For example, Fig. 6 D shows respectively from the extended line 100,101 of radially opposed surface 102,103 conllinear in zone 93.As shown in the figure, line 100,101 is with respect to longitudinal centre line C run-off the straight.Each bar line 100,101 all can limit an angle of inclination that is approximately 3 degree with respect to center line C.

As shown in Figure 3, a third channel part 104 can be set between channel part 20 and channel part 47.Third channel part 104 is illustrated with respect to channel part 20,47 has less or a shrink cross sectional dimensions.This shrinkage has increased the flow velocity in third channel part 104, and has increased the pressure of the material in the channel part 20,30.Wishing that for given material third channel part 104 can optionally have the cross sectional dimensions greater than channel part 20,47 under the reduction flow rate conditions.As will be appreciated that, the size of third channel part 104 can change, so that increase flow velocity at the needs of given material.In addition, the tapering of channel part 20 or narrow down degree can according to the material type with and required flow velocity change.

The major advantage of actuator 12 is, utilizes core rod 15 to make channel part 20 and allow that this channel part 20 forms in the individual unit operation, and need not other complicated mold component.Core rod 15 is textural simple relatively.

Following table 1 has comprised the example sizes that is used for according to an example of the present invention.Following size does not constitute a kind of restriction, but only is used for example.(unit of all sizes is millimeter, unless otherwise specialize.)
