Screw rod 72 and the second screw rod 74 are opposite spiral, when rotating hexagonal set 73, the first screw rod 72 and the second screw rod 74 simultaneously to
It is retracted in hexagonal set 73 or thinks to extend outside hexagonal set 73.Before driving motor 64 is assembled in air-exhausting duct 32, shorten the first spiral shell
The total length of bar 72, the second screw rod 74 and hexagonal set 73, enables support component 7 to be assembled in air-exhausting duct 32, then rotates
Hexagonal set 73, so that the second screw rod 74 contradicts on the inner wall of air-exhausting duct 32, to play the role of fixed driving motor 64.
With reference to Fig. 5, setting contradicts plate 75 on the second screw rod 74, contacts on contradicting plate 75 with the tube wall of air-exhausting duct 32
Rubber pad 76 is arranged in position, and rubber pad 76 and conflict plate 75 are respectively provided with radian identical with 32 inner wall of air-exhausting duct, convenient for supporting
Touch panel 75 and air-exhausting duct 32 are preferably bonded, while rubber pad 76 further protect air-exhausting duct 32(to refer to Fig. 3) tube wall not by
It destroys.
With reference to Fig. 5, card slot 77 is set on the shell of driving motor 64, and snap ring 71 is connected in card slot 77, to avoid
Driving motor 64 is moved along 71 axis direction of snap ring, and rubber sleeve (not shown) is arranged in card slot 77, is driven from effective protection
Dynamic motor 64 will not be clamped by snap ring 71 and be deformed.
With reference to Fig. 4 and Fig. 5, step 65 is set in one end of shaft 6, the side of step 65 contradicts the shaft in fixed plate 5
6 other end contradicts on the output shaft of driving motor 64 so that the position of shaft 6 is fixed, prevent the gear teeth 67 with
Jack 66 falls off, and causes blade 61 that can not rotate.
Blade 61: being plugged into shaft 6 by action process first, and shaft 6 is fixed on and is assembled in fixed plate 5, then will
Driving motor 64 is assembled on air-exhausting duct 32 and the gear teeth 67 are plugged into jack 66；Then when air quality sensor 1 incudes
When to indoor air quality difference, signal is passed into controller, controller controls air extractor 3 and driving motor 64 simultaneously,
So that driving motor 64 rotates, band movable vane piece 61 to be staggered between blade 61 and venthole 51,3 pairs of air extractor indoor progress
Then pumping is discharged by venthole 51, extraneous air enters the room after being filtered by filter 2, to play in clean room
The effect of air；Finally, air extractor 3 stops working after indoor air purification, 64 drive shaft 6 of driving motor is anti-
Turn, so that blade 61 covers in venthole 51.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
