223.Certainly, the first occlusion part 321 and the second occlusion part 322 also can be turned to other rotational positions, to wind path and wind
Amount is adjusted.
In other further embodiments of the invention, as shown in figure 11, regulating part 30 does not include throughput 33.When
In the case where only one occlusion part 32, the two sides of occlusion part 32 allow air-flow to pass through.When regulating part 30 has multiple occlusion parts
In the case where 32, the interval between every two adjacent occlusion part 32 allows air-flow to pass through.In this embodiment, each block
The both ends in portion 32 all have the first gasket 71.
Specifically, in some embodiments, the quantity of air outlet 22 be three, along pedestal 23 circumferential direction successively between
Every setting.These three air outlets 22 include the first air outlet 221, the second air outlet 222 and third air outlet 223, along pedestal 23
Circumferential direction and can successively be spaced setting in the counterclockwise direction.The quantity of occlusion part 32 is two.Two occlusion parts 32 are distinguished
For the first occlusion part 321 and the second occlusion part 322, can be set along the circumferential direction and being successively spaced in the counterclockwise direction of pedestal 23
It sets.First occlusion part 321 can be configured to allow its completely obscured air outlet 22.Second occlusion part 322 can be configured to allow
Its completely obscured two air outlet 22.Interval between first occlusion part 321 and the second occlusion part 322 can be configured to allow its complete
One air outlet 22 of exposure entirely.When the first occlusion part 321 and the second occlusion part 322 do not cover air outlet, the first air outlet
221, the second air outlet 222 and third air outlet 223 are in opening state.When the second occlusion part 322 completely obscured second goes out
When air port 222 and third air outlet 223, the interval between two occlusion parts 32 can make the first air outlet 221 be in be completely exposed
State.When the first occlusion part 321 can completely obscured first air outlet 221 when, the second occlusion part 322 can completely obscured third outlet air
Mouthfuls 223, the interval between two occlusion parts 32 can be such that the second air outlet 222 is in state is completely exposed.When the second occlusion part 322
Can completely obscured first air outlet 221 and when the second air outlet 222, third air outlet 223 can be made to be in, state is completely exposed.When
First occlusion part 321 can completely obscured third air outlet 223 when, the first air outlet 221 and the second air outlet 222 are in completely sudden and violent
Dewiness state.When the second occlusion part 322 only can completely obscured first air outlet 221 when, the second air outlet 222 and third air outlet
223 in being completely exposed state.When the first occlusion part 321 can completely obscured second air outlet 222 when, at the first air outlet 221
Interval between the state that is completely exposed, two occlusion parts 32 can make third air outlet 223 be in state is completely exposed.
