As for air door adjust；Machine control formula is that power type holds button or infrared ray is adjusted.Filtration system：Dirt bag, preceding filter, rear filtering
Piece.It is divided by filtering material difference：Papery, cloth, SMS, extra large pa (HEPA high efficiency filters material).
The operation principle of dust catcher is motor of dust collector high speed rotation, and air is sucked from suction inlet, so that dirt case is generated certain
Vacuum, dust by scrubbing brush, take over, handle, hose, main suction pipe enter bag dust filter in dirt case, dust is left on bag dust filter
Interior, filtered air enters motor using one layer of filter, this layer of filter is to prevent dirt bag rupture dust sucking motor
One of protective barrier, the air into motor is flowed out through motor, since carbon brush is constantly worn in motor operation, therefore flow out
Add again before dust catcher and has filtered together.
And dust catcher there is a problem of one it is more notable, under the interference of some corners or barrier, due to suction nozzle compared with
Greatly, so entire suction face will appear dead angle under the obstruction of barrier, the cleaning effect of corner is influenced, corner is caused to be easy product
Ash, and the shape of different barriers, corner is different, so cannot uniformly be handled, and the size for changing suction nozzle certainly will be to clear
Clean efficiency generates strong influence.

Hold the direction setting in portion 200.So, the effect of a positioning can be played, while total end can be made to have
There is supporting role, prevents from squeezing or colliding on influence caused by structure itself.
It is provided with support spring 421 between first loop bar 410 and the grip part 200.By the setting of spring, rise
The effect buffered to one ensures movement all in tolerance band, while 410 stress of the first loop bar, ensures the first loop bar 410
Service life, while the reserve travel of the first loop bar 410 and the second loop bar 420 under the extruding of regulating part 430 being provided, it reduces rigid
Property contact occur mechanical wear.
The controller further includes take-back strategy, and the recycling plan is executed after the controller completes the control strategy
Slightly, the take-back strategy includes
The length value of the shortest adjusting rod of length in adjusting rod is obtained, all adjusting rod work of control are so that length etc.
In acquired length value.The instruction of each data is recorded according to infrared encoder or by controller first, so that it may to judge
The length of each adjusting rod, the purpose of take-back strategy are that controlling adjusting rod shortens so that adjusting rod has reliable length, guarantor
What card was adjusted is normally carried out.
The fixed part 300 is set as circular ring shape, and the fixed plate 310 sets at least to 12, the distance measuring unit 330
And the quantity of the adjustment portion corresponds to the setting of the fixed plate 310.It is arranged in this way, it is various improves the variation that shape adapts to
Property, ensure that change in shape more meets with tested surface, it is relatively simple reasonable.
Certainly, the representative instance of the above only present invention, in addition to this, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
