Driving, such as the rotation leaf of the first wheel rotor 4, the second wheel rotor 3 are arranged to fan blade, and the blower in air purifier provides
Wind promote the first wheel rotor 4, the second wheel rotor 3 towards open outlet air direction rotate, when the blower in air purifier
After stopping working, the first wheel rotor 4, the second wheel rotor 3 are inverted to by means of the reset force of elastic component or spring and are closed out
The state in air port.
As shown in figure 3, fixed impeller 2 includes hub 20 at its center, around multiple fixed leaves of the distribution of hub 20
21 and multiple fixed 21 peripheral sides of leaf of connection outer ring 23.
With continued reference to Fig. 3, the first wheel rotor 4 includes multiple turns of hub 40 and circular hub 40 at its center
Movable vane 41.
With continued reference to Fig. 3, the second wheel rotor 3 includes multiple turns of hub 30 and circular hub 30 at its center
Movable vane 31.
In one or more embodiments, fixed impeller 2 could alternatively be other structures form, such as only include hub
It with multiple fixed leaves, is fixed on inside air purifier by hub, can only include multiple fixed leaves, this is more for another example
A fixed leaf links into an integrated entity or split settings, and is fixed on the inner wall of side shell 5.
Equally, the first wheel rotor 3, the second wheel rotor 4 also could alternatively be other structures form, such as its multiple turns
Movable vane is fixed in outer ring.
In Fig. 1 into embodiment shown in Fig. 7, specifically referring to Fig. 3, motor 1 includes output shaft 11, when output shaft 11 is suitable
Hour hands rotation, drives the first wheel rotor 4 to rotate together.It is provided with convex block 400 in the hub 40 of first wheel rotor 4, second
The groove 300 being arranged in the hub 30 of wheel rotor 3, convex block 400 are placed in groove 300, and the length of groove 300 is greater than convex block
400, when the first wheel rotor 4 starts to rotate clockwise, convex block 400 is located at 300 left side of groove, can slide to the right.Until convex
It is in contact on the right side of block 400 and groove 300, at this point, the second wheel rotor 3 rotates together under the drive of convex block 400.Similar,
It is provided with convex block 301 from the second wheel rotor 3, is arranged fluted 200 on fixed impeller 2, when the second wheel rotor 3 starts to revolve
When turning, convex block 301 is driven to slide together, until convex block 301 is in contact with groove 200.Since fixed impeller 2 is fixed on clarifier
Body on, the first wheel rotor 4 and stop rotating at this time from the second wheel rotor 3 due to the blocking of fixed impeller 2.Such as figure
Shown in 6 and Fig. 7, after rotation, the first wheel rotor 4 and just it is hidden under fixed impeller 2 from the second wheel rotor 3
Face.
Conversely, as shown in Figure 6 and Figure 7, when air purifier receives shutdown command, the axis of motor 1 starts counterclockwise
Rotation drives the first wheel rotor 4 to reversely rotate first, after being in contact on the left of convex block 400 and groove 300, the first rotation leaf
It takes turns 4 and is rotated together from the second wheel rotor 3, until the two is run in place.At this time the first wheel rotor 4, from second rotation leaf
Wheel 3 and fixed impeller 2 form closed surface, and dust is prevented to pass through.
From a kind of mounting means for being recognized that wind outlet unit in embodiment as shown in the figure in Fig. 3, spiral shell is used first
The body of motor 1 is fixed in the hub 20 among fixed impeller 2 by nail.It then will be from the hub among the second wheel rotor 3
In 30 sets of hubs 20 among fixed impeller 2, then by 40 sets of hub among the first wheel rotor 4 in the second wheel rotor 3
In the hub 30 at middle part, while the sleeve column 402 on the first wheel rotor 4 is in the output shaft 11 of motor 1, and with screw by two
Person fixes.Finally fixed impeller 2 is fixed on side shell 5.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art without departing from the spirit and scope of the utility model, can make possible variation and modification.Cause
This, all contents without departing from technical solutions of the utility model, according to the technical essence of the utility model to above embodiments institute
