The handle 20 has outer wall 200 and inner wall 250, is defined at least partly across the primary fluid flow road of handle 20
Diameter 400.The second end 24 of the inner wall 250 from ontology 30 towards handle 20 extends to downstream end 254.The handle 20 is tubulose
, and the outer wall 200 of handle 20 is by any material appropriate (such as molded plastics or rolled metal plate (such as aluminium, aluminium alloy
Or steel)) manufacture cylindrical sleeve.The handle is connected to ontology 30 in first end 22, and at distal end, the second end 24,
Main fluid entrance 40 is set.The main fluid entrance 40 is first device of the filtering into the fluid of major fluid flow path 400.
Referring now to Figure 3, inner lining material 270 is positioned between inner wall 250 and outer wall 200.The inner lining material 270 is bubble
Foam or felted terxture, when the noise that fluid is aspirated into its generation that at least decays of handle 20 by fan unit 70 (has and eliminates the noise
Effect).For clarity, inner lining material 270 is shown as the part only around inner wall 250.In order to enable inner lining material
270 and major fluid flow path 400 in fluid stream between can contact, thus noise attenuation, inner wall 250, which is provided having, to be worn
Hole 256, the perforation 256 surround and extend at least partly along the length of inner wall 250.
Inner lining material 270 is provided to be aspirated into main fluid in operation of the fluid by fan unit 70 and enters to reduce
The noise generated when mouth 40.
There is diameter, the diameter to be selected as most effectively weakening noise for the perforation 256 of inner wall 220.1 millimeter to 10 millimeters
Diameter be suitable, smaller diameter for obtaining better sound power (reducing the sound in primary human's range of sounds)
Be better and larger diameter it is good for high-frequency decaying.The perforation is preferably formed as the surface district of inner wall 220,250
At least the 40% of domain.
By the way that inner lining material 270 is arranged in 250 rear of inner wall, enabling use is directly more sudden and more violent than inner lining material 270
The inner lining material thickness of the case where revealing major fluid flow path bigger.This is because the diameter of major fluid flow path 400 is
It is limited by inner wall 250, which is squeezed into inner lining material 270 in the gap between the inner wall 250 of handle 20 and outer wall 200
In.Typically, which between 4 and 6 mm of thickness but will be compressed between outer wall 200 and inner wall 250.
Important feature with multilayer handle 20 is that material property can be used for improving subtracting for the noise generated by product
Gently.Inner lining material 270 is passed through by fan unit 70 and the noise of air for the fluid stream movable property life for entering major fluid flow path 400
Decaying, however some noises are transmitted through inner lining material 270.
Supplementary features needed for handle 20 be it is firm enough to provide the handle that can grasp, will not allow it is flexible, and
Constraint can be introduced major fluid flow path by this bending.Therefore, material (such as aluminium or carbon fiber reinforced composite) is reason
Think, because they provide light and firm pipe.Alternatively, outer wall is made from a plastic material.Those skilled in the art will
Recognize that other materials will provide similar benefit.
In order to enable the diameter of handle 20 is not excessive for user, the thickness of outer wall 200 is preferably smaller than 2 millimeters, and
More preferably less than 1 millimeters thick.It is desirable that about 0.7 millimeter of the thickness.Outer wall with relatively thin handle 20 also reduces product
Weight.
When with high-speed electric expreess locomotive, the noise of generation is high-frequency, some noises can stimulate the ear of people.However,
When can more effectively decay high-frequency when this with advantage.
The handle diameters are ideally between 20 and 60 millimeters, and preferably between 30 and 50 millimeters.Most preferably, hand
Shank diameter is between 35 and 42 millimeters.In order to which the mitigation of noise is maximized and provides the handle that can be grasped, the utility model
The combination of material has been used in handle 20.Outer layer 200 is hard and thin first, so that passing through noise elimination medium i.e. inner lining material
270 sound attenuating in handle 20 can be maximized by maximizing the thickness of the inner lining material 270 in handle 20.It is ideal
Ground, at least 6 millimeters of inner lining material 270 or noise elimination medium are by demand with the noise of the higher frequency for the high-speed electric expreess locomotive generation that decays
(typically about 1.8 to 2Khz).
Referring now to Figure 7, the length of inner lining material 270 is also critically important.It is desirable that in the upstream of motor 70 and in electricity
The downstream of machine 70 all has inner lining material 270, this is because motor generates noise when fluid enters motor and leaves motor.
Referring now to Figure 10, which show the noises generated by high-speed electric expreess locomotive in handle 20 about fan unit 70 to entrance
The diagram of 40 distance.Normally, the length of liner deadener the long, and more sound is attenuated, but exists and produced to one
Product can how long and still practical limitation.Therefore, right from the aspect of noise for the hair dryer with motor in handle 20
In length of the motor in handle 20, there are optimum positions.When motor moves away from entrance along X-axis line, Inlet muffler
More long, more sound are attenuated, as it can be seen that the x-axis noise along entrance 280 is reduced in as shown.However, for given
The length l of handleh, Inlet muffler SIMore long then outlet noise silencer SOIt must be shorter.
For outlet noise silencer SOIf motor is located in inlet (zero of x-axis), for outlet noise silencer SO
Outlet noise level 282 for the decreased food l that provideshIt is minimized, then when motor is along handle motion, outlet silencing
Device SOLength is reduced and sound attenuation is reduced, therefore sound levels rise.Therefore there are the optimums for motor to entrance
Distance.In scale-up version hair dryer, wherein major fluid flow path 400 flows into ontology 30, primary fluid stream from handle 20
Circular cross section 400a of the shape and size in dynamic path out of handle becomes to intrinsic annular or circular cylindrical cross-section 400b
Change.For this reason, because some noises generated by fluid discharge motor are entered the attenuating fluid of ontology 30, in handle
Entrance and exit silencer in terms of sound and differ.
From Inlet muffler SIWith outlet noise silencer SOCombination noise output 284 be diagram on compressor value, work as motor
It is reduced first to reach sweet spot when being moved away from entrance, at this point Inlet muffler SIWith outlet noise silencer SOIntersection,
Then it increases again.
Total noise output 288 of hair dryer is that (it is the ontology 30 of hair dryer for compressor value 284 and amplifier value 286
The noise of interior generation and this value is not influenced by the position of the motor in handle 20) the sum of.For this specific hair dryer,
Optimum Inlet muffler SIIt is 70 to 100 millimeters.However, if in such as motor speed, handle diameters or inlet features
Any one be changed, this value will change.
Preferably, outlet noise silencer SOLength (from the downstream end 70b of fan unit 70 to the downstream end of handle 20
22) up to 100 millimeters long.Preferably, Inlet muffler SI(from the upstream end thereof 70a of fan unit to the downstream of entrance 40
Portion 40b) it is 10 to 200 millimeters long.Preferably, Inlet muffler SIWith outlet noise silencer SOBetween ratio be more than 1.2.Having

The utility model another feature is that the fluid in major fluid flow path 400b in ontology 30 relative to hand
The fluid in major fluid flow path 400a in handle 20 is in 90 °.Primary fluid stream in ontology 30, which is parallel to, flows through fluid
The fluid of flow path 300.
Referring now to Figure 2,3a and 9, internal pipeline 310 has generic tubular part 312, and (it is from 340 direction of fluid outlet
Fluid inlet 320 extends) and substantially conical section 314, formation side wall 350, the side wall are connected to 312 He of generic tubular part
Between the outer wall 360 of ontology 30.
The side wall 352 can be perpendicular to outer wall 360, as shown in fig. 17 a.In fact, independent side wall 350,352 can be saved
Slightly, and internal pipeline 354 can be used as cylinder and extend from fluid inlet 320, have to go out towards fluid in the form of frustoconical
The diameters that mouth 340 is gradually reduced.
With reference to figure 18a, internal pipeline 354a extends from outer wall 360 at first end 32 and the direction at the second end 36
Form the tube bending of circular pipe.The form generated by internal pipeline 354a is horn shape.Figure 18 b are shown and Figure 18 a
In the similar internal pipeline 354b of internal pipeline, however, the conical section 358 of internal pipeline 354b is shorter, to provide
To the precipitous gradient of fluid inlet.
The internal pipeline being gradually bent has the benefit that noise is reduced, because fluid is at fluid inlet 320
The turbulent flow less into there when fluid flow path is generated.Due to being entered the flowing of fluid flow path 300 by volume inspiration not
Any wedge angle (it will introduce the generation for being vortexed and increasing noise) is met with, it is being acoustically beneficial to have crooked sidewall.The side
Wall is by the tubular portion of involvement internal pipeline 310.
Figure 18 c show the combination of internal pipeline 354a and opening hole 354c in Figure 18 a.The internal pipeline 362 is from
One end 32 extend to transition point 364 (at this have gradually reduce diameter cylinder change with towards the second end 34 slightly
Ground increases diameter).This of internal pipeline opens the volume suction increased into the fluid of fluid inlet 320.
Figure 18 d show the combination of conical section 358 and opening internal pipeline 354d in Figure 18 b.By making inside
Pipeline 354d has shorter conical region, which can be longer.
In fact, any angle between 1 ° and 90 ° can be selected for outer wall 360 and internal pipeline 350,354a,
Angle beta between 354b, 354c and 354d.
With particular reference to Figure 18 c and 18d, the tubular portion 312 of conical section 358,362 and internal pipeline 354d, 354c it
Between radius r it is alterable.The radius is preferably between 0.5 and 50 millimeter.
Alternatively, which can increase diameter from side wall 366 towards fluid outlet 340, such as Figure 17 b and 17c
Shown in.This is favourable, because it increases the flowing inhaled by volume across fluid flow path 300.Therefore or go out from fluid
Mouthfuls 340 and primary fluid outlet 440 total transmitting be increased or fan unit can be generated being run compared with low velocity it is equal total
Output, reduce the noise of product.The increase of the diameter of the internal pipeline 310 becomes apparent from Figure 17 c, and more multireel is caused to be inhaled
Across internal pipeline 310.
Referring now to Figure 7, the length of the inner lining material in handle 20 is alterable.Preferably, Inlet muffler SILength
(from the downstream end 40b of entrance 40 to the upstream end thereof 70a of fan unit 70) is 10 and 200 millimeters.
The front part 38 of hair dryer can have (the institute in such as Fig. 1,2,6,19a and 19b of various chamfered sections 372,374,376
Show), which is the variation of the diameter of the outer wall 360 of ontology 30.The diameter is towards outer wall 360
Center A-A is reduced.Since fluid is from the movement of primary outlet 440, which influences from the outer of hair dryer
The foreign volume of side inhales 490.Limitation is inhaled 490 for foreign volume and is used for across fluid by the stiff anterior face for ontology 30
The flowing of the fluid of flow path 300.It is desirable that before between 30 ° (as shown in figure 19 a) and 60 ° (as shown in figure 19b)
Portion's chamfered section is selected.Preferably, between 35 to 55 ° and more preferable 45 ° of front chamfered section is provided because this provide it is reasonable
The foreign volume of amount inhales 490.
The direction of the fluid of primary fluid outlet, which is discharged, to be changed according to the desired result.Figure 20 a, 20b and 20c are shown
Different air for main fluid are discharged.Display refers to figure 20a, and primary fluid outlet 440 is with the one 442 and the 2nd 444 substantially
Parallel surfaces, the corresponding outer annular boundary and inner annular boundary limited for primary fluid outlet 440.One 442 He
2nd 444 general parallel orientation surface again with 310 general parallel orientation of internal pipeline.This arrangement provides foreign volume and inhales fluid 490 and inside
Volume inhales the balance between fluid 492 (fluid for being namely aspirated into fluid flow path 300).
In Figure 20 b, major fluid flow path 440a is directed toward the center of the outer wall 360 of ontology 30.In this reality
It applies in example, the one 446 and the 2nd 448 surface for limiting primary fluid outlet 440a is essentially parallel to each other but relative to internal pipeline
310 tilt.Primary fluid outlet 440a is directed toward the center of internal pipeline 310 and external body 360.Discharge main fluid goes out
The fluid 494 of mouth 440a is directed toward the fluid emitted from fluid outlet 340, as foreign volume suction fluid 490.Due to stream
Body is all directed toward the interior roll suction fluid for flowing through internal pipeline 310, this is defeated to more concentrating for hair dryer is come from
Go out, be thus concentrated to due to the fluid sprayed from hair dryer in smaller cross-sectional area, which will feel more strength
's.This arrangement will provide foreign volumes relatively more more than the non-inclined embodiment described in Figure 20 a and inhale fluid 490 and inside
Less interior roll in pipeline 310 inhales flowing.
In Figure 20 c, primary fluid outlet 440b is directed away from the center of the outer wall 360 of ontology 30.In this embodiment
In, the one 450 and the 2nd 452 surface for limiting primary fluid outlet 440a is essentially parallel to each other but is inclined away from internal pipeline 310.
Primary fluid outlet 440b is directed toward outer wall 360.The fluid 496 of discharge primary fluid outlet 440b is directed away from from fluid
It exports the fluid of 340 transmittings and inhales fluid 490 towards foreign volume.When fluid is all guided outward, this is come from hair dryer
The output more spread, thus because from hair dryer spray fluid be transmitted into larger cross-sectional area, the hair dryer will
Feel less strength.This arrangement will provide foreign volume relatively more less than the non-inclined embodiment described in Figure 20 a and inhale
Fluid 490 and along internal pipeline 310 relatively more interior rolls inhale fluid.
Figure 21 shows that the accessibility of the control button of hair dryer 10 and location control button 64 (shown in Fig. 2) are being done
Send out the ergonomics benefit on the angled surface of the ontology of device.When hair dryer is normally caught by handle 500, by used
Example thumb will be positioned as forming entire or partial turn around handle and index finger 502.In this hair dryer 10, thumb 504 can be pressed
Convention is caught, but the thumb is also operable with by side wall 350, (it forms one of the fluid inlet 320 at the rear portion of product
Point) on control button 64 change setting (such as temperature and/or flowing across hair dryer).Therefore, in addition to by thumb from
In the case that handle 20 radially arrives except the possibility movement of side wall 350 without adjustment grasping, hair dryer 10 can be changed in user
Setting.The side wall 350 is angled preferably with respect to the outer wall 360 of ontology 390.The angle γ ideally between 1 ° and 90 °, and
It is preferred that between 30 deg. and 60 deg..It is most preferred that the angle γ, which is 45 °,.
Figure 22 a show the diagram of the VELOCITY DISTRIBUTION across hair dryer 10.At fluid inlet 40, into fluid inlet 40
Fluid in relatively low speed 402, when fluid passes through Inlet muffler, speed 404 is with the cross section face in handle 20
Product reduces and increases.Similarly, when fluid enters fan unit, due to the fluid of motor and impeller across fan unit 70
The further limitation of flow path 400, speed 406 increase again, and in the upstream of fan unit 70, when fluid flow path again
When secondary less limitation, the speed 408 of outlet noise silencer is passed through to reduce.When fluid travels into from handle 20 ontology of hair dryer 10
Minimum speed 410 is reached when 30.This is because ontology 30 has the cross-sectional area than handle bigger and serves as gas chamber (it is filled
Flowing full body, to slow down fluid).In the ontology, speed 410 is similar to the speed at entrance 402.When fluid passes through heating
When device 80, it is restricted to fluid stream since heating element offer is small, speed 412 slightly increases.When fluid goes out close to main fluid
When mouth 440, the cross-sectional area in ontology 30 is reduced to the ring for limiting primary fluid outlet 440, and intrinsic speed is in mainstream
Increase to maximum speed 414 at body outlet 440.
Making speed reduce when fluid moves to heater 80 from fan unit has several advantages：Ontology 30 is shown as
Gas chamber (as circular flow 400a of the fluid out of handle 20 to annular fluid 400b in ontology 30, it stablizes the fluid).Stream
This deceleration in body can more uniformly flow through heater 80, therefore speed and turbulent flow are reduced, by hair dryer
The noise of generation is reduced, and there is load evenly around the ring for forming primary fluid outlet 440.
The main reason for speed is reduced from fan unit speed 406 to heater speed 412 is the cross of fluid flow path
Area of section area A from the circular flow 400a in handle1To the cross-sectional area A in the annular fluid 400b in ontology 302
Variation, this is shown schematically in Figure 22 b, A2>A1。
Although the outer wall 200 of handle 20 has been described as being manufactured by rolled metal plate, the manufacturing method and material of replacement can
It being used, these include but is not limited to, extruded tube and plastics extruding/molded tube or composite material tube (such as fibre reinforced
Plastics).
The utility model is described in detail about hair dryer, but it is applicable to sucking fluid and guides the stream
Any utensil that body is flowed out from utensil.
The utensil can be used together with heater or can not be used together with heater；The effect that fluid flows out at high speeds
With drying effect.
The fluid flowed by utensil is usually air, but can be the various combination of one or more gases, and
It may include additive, for improving the influence of utensil performance or utensil to the be aligned object of output, which is, for example, hair
With the hair style of hair.
The utility model is not limited to detailed description given above.A variety of variants will be aobvious for those skilled in the art
And it is clear to.
