One direction need not be overlapped, and can have certain angle, and the angle of blowing device 100 is held depending on user.When so that blowing fills
Set 100 longitudinally and when the consistent mode of first direction is held, the axis direction of the air outlet of first direction and air hose 160
Unanimously.The air-flow face blowing object blown out when blowing device 100 travels forward at this time, has stronger airflow effects.
When blowing device 100 makees translation in a second direction to be moved back and forth, i.e., when left and right sweeps blowing, similar left and right is swept
Swing when dynamic blowing moves back and forth, and the track that the translation in second direction moves back and forth includes intermediate region A and two side areas
B, wherein fan 130 is in intermediate region A with First Speed V1 blowout air-flow for blowing device 100, the fan in two side areas B
130 blow out air-flow with second speed V2.Intermediate region A is main blowing object, and in intermediate region, A keeps high speed blowing to guarantee to blow
Wind effect；Two side areas B is secondary regions, low speed blowing is kept, to reduce energy consumption.The second of fan 130 in two side areas B
Speed V2 can be close in 0.
Under the operating mode for automatically switching revolving speed, air velocity is with the side of First Speed V1 and second speed V2 interval variation
Formula is blown out from air hose 160, and wherein First Speed V1 is greater than second speed V2, to form the impact air-flow of moment.
In one embodiment, the operating mode for automatically switching revolving speed can be the first operating mode, the second operating mode
And one in third operating mode.First, second and third operating mode is different from speed stabilizing operating mode, they are configured as
It is as described below:
In the first operation mode, First Speed V1 is less than or equal to motor 120 and is worked with aforementioned scheduled constant rotational speed
When fan 130 generate air velocity.That is the First Speed V1 of the first operating mode is less than or equal under speed stabilizing operating mode
Air velocity VIt is fixed.Join Fig. 6, under the first operating mode, the first revolving speed of the motor 120 when forming First Speed V1 is controlled as
Less than or equal to aforementioned scheduled constant rotational speed, the second revolving speed of the motor 120 when forming second speed V2 is less than aforementioned naturally
Scheduled constant rotational speed, so that First Speed V1 is less than or equal to air velocity VIt is fixed.Second speed V2 < First Speed V1≤VIt is fixed。
It will be appreciated from fig. 6 that compared with speed stabilizing operating mode, when hair dryer 100 is with the first mode of operation, 120 turns of motor
