Further, the rotating speed of movable vane wheel change synchronous with dust absorption fan suction.The rotating speed of the impeller is with suction
The increase of dirt blower fan suction and increase so that the suction of dust absorption fan increase while, by increasing capacitance it is possible to increase the rotating speed of impeller, then
So that the rotating speed of agitator arm also gets a promotion；When dust catcher runs into stain to be difficult to clean off, in the suction of increase dust absorption fan
While power, the rotating speed of agitator arm is also synchronous in increase so that stain can be more prone to remove.
Inventor does not utilize completely by the discovery that studies for a long period of time, the suction of the dust absorption fan of existing dust catcher, causes work(
The unnecessary waste of rate, and vacuum cleaning head of the prior art, motor can be all set inside vacuum cleaning head and drive agitation
Bar is rotated, and motor can take the inner space of vacuum cleaning head, and the power circuit of motor needs to pass through from cleaner head inside, by
Working environment inside vacuum cleaning head is poor, has situations such as there is the sharp thing of high speed and cut power line and cause short circuit.
A kind of vacuum cleaning head of the invention and the dust catcher using the vacuum cleaning head, can make full use of in dust catcher
The suction of dust absorption fan, drives the agitator arm in cleaner head to rotate using air-flow, makes full use of the suction of dust absorption fan, and described
The rotating speed of agitator arm is positive correlation with the suction of dust absorption fan, when dust catcher runs into the spot for being difficult to siphon away, it is necessary to increase suction
The suction of dirt device, simultaneously because the increase of the suction of dust absorption fan also improves the rotating speed of agitator arm, dust absorption fan and agitator arm
Synergy so that the removing that spot can be more prone to；Blower fan suction can also be adjusted with agitation speed change gear is increased
Relation between the rotating speed of bar, more fully using dust absorption fan.
