Specific embodiment
Make specific introduce to the present invention below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2, hair-dryer 100 includes motor 10, fan 20, casing 30, battery pack 40 and wind speed adjusting dress
Put 50.
10 driving fan 20 of motor is rotated around central axis 101.Specifically, fan 20 is aerofoil fan.Motor 10 is
Motor.Casing 30 accommodates motor 10 and fan 20.Battery pack 40 is powered for motor 10.Battery pack 40 is detachably connected to casing
30.Casing 30 is formed with the handle 31 held for user.Wind-speed adjusting device 50 is connected to casing 30, and wind-speed adjusting device 50 exists
In the case of not changing 10 rotating speed of motor, using the wind speed of the mechanical system adjustment output of hair-dryer 100.
As shown in Figures 2 to 5, wind-speed adjusting device 50 includes guide duct 51, movable part 52 and operating parts 53.
Guide duct 51 is the pipeline extended approximately along 101 direction of central axis.Guide duct 51 is formed with along central axis 101
The air duct 511 of direction extension.Air duct 511 has been oriented to the movement of air-flow, makes the air-flow that fan 20 generates along 101 direction of central axis
Movement.The both ends of guide duct 51 are respectively formed with air inlet 512 and air outlet 513.Air-flow enters air duct 511 from air inlet 512
It is flowed out from air outlet 513.
Movable part 52 is arranged in guide duct 51, and can move to change air outlet 513 relative to guide duct 51
Wind speed.Movable part 52 is slided relative to guide duct 51 along central axis 101.
Operating parts 53 is connected to movable part 52.Operating parts 53 supplies user's operation to adjust movable part 52 relative to guide duct 51
Position.
As shown in Figures 2 to 7, movable part 52 includes main part 521 and connecting portion 522.Main part 521 is used to be oriented to gas
Stream.It is gradually reduced along 101 direction main body of central axis, 521 diametrical size from middle part to both ends.Specifically,
Main part 521 is around the revolving body that central axis 101 is rotary shaft.Main part 521 is into shuttle-type.Convenient for smooth guiding air-flow,
Will not aspect of blowing efficiency be influenced due to the setting of main part 521.
Guide duct 51 is formed with the track 514 to match with connecting portion 522；Connecting portion 522 is slidably attached to track
514 enable movable part 52 to be slided relative to guide duct 51.
Operating parts 53 is connected to connecting portion 522, so as to make the mobile of operating parts 53 that movable part 52 can be driven to move.Operating parts
53 are equipped with positioning protrusion 531.Guide duct 51 is formed with the multiple gear grooves 515 coordinated with positioning protrusion 531.Positioning protrusion
531 coordinate with gear groove 515, lock operation part 53 relative to guide duct 51 position, so as to lock movable part 52 relative to
The position of guide duct 51.
Movable part 52 is two halves shell structure.Movable part 52 includes upper shell 523 and lower housing 524.Upper shell 523 is under
The assembling of housing 524 forms movable part 52.Cavity 525 is formed between upper shell 523 and lower housing 524.The weight of movable part 52 compared with
Gently, the preponderance of hair-dryer 100 will not be caused due to the setting of movable part 52, influences to operate and use.
As shown in Figure 5 and Figure 6, radially protruding of the middle part of guide duct 51 along central axis 101.Air duct 511 is around center
Axis 101 is the revolution of rotary shaft.Radially protruding of the middle part in air duct 511 along central axis 101.
Movable part 52 and the shape in air duct 511 match so that movable part 52 is located at different location relative to air duct 511
When, air-flow can advance along a channel seamlessly transitted so that will not in other words will not due to the setting of movable part 52
Since the movement of movable part 52 causes the channel deformation of airflow larger, aspect of blowing efficiency is influenced.
Movable part 52 has first position and the second position relative to guide duct 51.In Fig. 5, movable part 52 is located at first
It puts, movable part 52 is integrally located at far from air outlet 513, movable part 52 in air duct 511 at this time.Main part 521 is located at air duct 511
Interior and air duct 511 middle part is corresponding with the middle part of main part 521.
Movable part 52 is located at the second position in Fig. 6, and movable part 52 is close to air outlet 513 at this time, and movable part 52 is at least partly
By air outlet 513,52 at least part of movable part is located at beyond air outlet 513 except air duct 511 in other words.Main part 521 to
Small part stretches out air outlet 513.521 part of main part block air outlet 513 allow air-flow by area of section.Movable part
The wind speed of 52 air outlets 513 when being located at first position is less than the wind speed of the air outlet 513 when being located at the second position of movable part 52.Activity
Part 52 at first position air outlet 513 allow air-flow by area of section be more than the air outlet at the second position of movable part 52
513 allow air-flows by area of section.In the case that air quantity that fan 20 generates within the unit interval is identical, due to movable part
52 at first position air outlet 513 allow air-flow by area of section it is big, then the wind speed of air outlet 513 is low at this time.And it lives
The air outlet 513 when air outlet 513 is located at the second position of moving part 52 allow air-flow by area of section it is small, then air outlet at this time
513 wind speed is high.During movable part 52 is moved from first position to the second position, the wind speed of air outlet 513 gradually increases.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the invention is not limited in any way above-described embodiment, all to be obtained by the way of equivalent substitution or equivalent transformation
Technical solution is all fallen in protection scope of the present invention.
