Clean device 10 is placed on the S of surface using the imaginary plane that the base portion B provided by power supply 22 or power shell is limited.Cleaner
10 center of gravity is configured so that base portion B can steadily support cleaner 10 without turning over cleaner 10 on horizontal plane S
?.In addition, nozzle 12 is with respect to the horizontal plane since the axis X of nozzle 12 and the normal of the imaginary plane of base portion B are at an acute angle
S is oriented at least partly be directed toward, in order to which the bulk materials in nozzle 12 are further fallen into cleaner 10.Such as Fig. 3
Shown, the center of gravity WB of battery pack and the normal at the center of the plane by being limited by base portion B are coaxial.In addition, entire cleaner
Center of gravity CG is with distance b and base portion B vertically spaced and with distance a and base portion B forefront (before closer cleaner 10
Portion 10F) edge is horizontally spaced.The ratio of distance b and distance a is preferably 2.4 to 3, and more preferably 2.6 to 2.8, most preferably
It is about 2.7.
Fig. 4-Fig. 5 shows the list of separator 16 and dirt collector 18 on second side 10R for being configured in cleaner
A openable lid 30, is used to open simultaneously separator 16 and dirt collector 18.Lid 30 can be in cyclone separator 16
Top end have hinge 32 hinged door.
In operation, battery 22 provides electric power to motor and fan 20, to generate the suction airstream sucked by nozzle 12.
Air-flow with dirt enters the dirty air entrance of cyclone separator 16 along nozzle 12.Air-flow and dirt enter cylindrical wall
16C, air-flow and dirt are rotated around longitudinal axis Y wherein.The rotation of air-flow and dirt can be such that dirt separates with air-flow, and
Dirt exports discharge cylindrical wall 16C by dirt.It is fallen in dirt collector 18 by isolated dirt.Purification air passes through
Form the antipriming pipe 16P of the clean air outlet of cyclone separator 16.Then the air-flow purified passes through motor prefilter chamber
Enter suction source 20.Air-flow passes through motor prefilter first before through suction source 20.After through suction source 20,
Air-flow is discharged by exhaust outlet (not shown) from cleaner 10.
After having used cleaner 10 (for example, after completing clean up task), user can be by by battery pack 22
Base portion B be placed on the S of surface cleaner 10 be placed on the S of surface.Orientation due to nozzle 12 relative to base portion B,
Impact force during placement can stir the loose dirt in nozzle 12, allow loose dirt under the effect of gravity by into one
Inwardly guidance is mobile towards separator 16 and dirt collector 18 for step.It is simultaneously clear to empty dirt chamber 18 that user can also open door 20
(dirt can be collected in after use for several times on antipriming pipe 16T and cylinder by clean cyclone separator chamber 16 and antipriming pipe 16T
In shape wall 16C).User can also open the lid 26 of the motor prefilter chamber on 10 other side of cleaner when needed, with
Cleaning or replacement motor prefilter.
Fig. 6 and Fig. 7 shows the hand vacuum cleaner 10' in another embodiment of the invention, and structure is similar
The structure of cleaner 10 in Fig. 1-Fig. 5.Fig. 6 shows the flow path of dirt in operation.Dirt is from nozzle 12'
Entrance enter, enter single stage cyclone 16' in bottom end, the cylindrical wall rotation around single stage cyclone 16' is big
About 360 degree, and dirt collector 18' is fallen into non-perpendicular angle.Fig. 7 shows the flow path of air in operation.
Dirty air enters from the entrance of nozzle 12', in bottom end by entering single stage cyclone 16', separates around single stage cyclone
Dirt is separated while the cylindrical wall rotation of device 16'.Then pass through antipriming pipe enters the pre- mistake of motor to the air of opposite purification
Then filter chamber is discharged by motor 20' and from cleaner 10'.
