The central rotating cone of the inner orientation of the main body, and the cone is positioned at least partially at the institute of the major part
State the lower section of part.
This structure allows to manufacture auxiliary discharge conduit from main body, and therefore allows to reduce noise, and keeps this simultaneously
The compactedness of kind dust catcher, because the additional conduits for the size that can increase this dust catcher need not be added.
According to feature of the present utility model, the major part includes the first wall, and the slave part includes second
Wall, and first wall and second wall form the auxiliary discharge conduit.
By this way, it is not necessary to increase the material for obtaining auxiliary discharge conduit, this, which allows not increase weight, does not also increase
Large scale.
According to feature of the present utility model, the hand-held cleaners include motor, and the motor includes rotation axis, described
Rotation axis is roughly parallel to the rotation axis of the central rotating cone.
This feature causes with motor, the motor orientation with circulation air stream direction it is identical, this permission not with
The air stream interference, therefore do not produce load loss.
According to feature of the present utility model, the Cyclonic separating apparatus includes rotation axis, and the rotation axis substantially hangs down
Directly in the cone or the rotation axis of the motor.
This feature causes the compactedness for optimizing Cyclonic separating apparatus.
According to feature of the present utility model, the externally ported rotation axis around the cone of the auxiliary discharge conduit
Along the angle extension between 10 ° and 300 °.
This feature causes to make described externally ported be dimensioned in the amount of the air of discharge.
According to feature of the present utility model, it is described auxiliary discharge conduit it is externally ported formed on the body between
5cm2And 20cm2Between and preferably 16cm2Area.
According to feature of the present utility model, the dust catcher includes the baffle plate positioned at the exit of the main intake guide,
Air-flow to be separated and made the air stream of a part oriented towards the auxiliary discharge conduit of air and to make another portion
Point air stream is oriented towards electronic card so as to which the electronic card is cooled down.
According to feature of the present utility model, sound-proof foam is arranged in the auxiliary exhaust conduit.
The foam causes further to reduce the speed of air-flow and therefore reduces noise.

9.Between the two conduits, the main body 2 includes aspirating mechanism 7, and the aspirating mechanism 7 is produced through the main He of intake guide 6
The air stream of auxiliary exhaust conduit 8.In other words, air sucked by main intake guide 6 and by auxiliary exhaust conduit 8 outside
Discharged at portion outlet 9.One implement modified example in, unshowned sound-proof foam may be provided in auxiliary exhaust conduit 8 so as to
Further reduce the speed of air and therefore reduce noise.
Gripping handle 5 is fixed in the main body 2.Gripping handle allows user to operate hand-held cleaners 1.In this practicality
In new embodiment, the gripping handle 5 is located at below the main body 2 to be operated so as to be more convenient for, but in others not
In the embodiment shown, the settable other positions on the body 2 of the gripping handle 5.
Hand-held cleaners 1 also include the Cyclonic separating apparatus 4 of dust.The Cyclonic separating apparatus 4 of the dust can have one
Individual or multiple levels and its object is to separate and filter dust.The Cyclonic separating apparatus 4 is fixed in the main body 2.It is described
Cyclonic separating apparatus 4 be located at the lower section of main body 2 so as to it is vertical with the main intake guide 6 and with main intake guide 6 with pneumatic
Mode connect.Cyclonic separating apparatus 4 is set along the rotation around rotation axis Δ 3.The rotation axis Δ 3 is substantially vertical
In main intake guide 6, as shown in Figure 1.Cyclonic separating apparatus 4 has a level.
In another unshowned implementation modified example, Cyclonic separating apparatus 4 can have two levels.
As shown in Fig. 2 the aspirating mechanism 7 is made up of motor 7.The motor 7 is set around and along rotation axis Δ 2
Put.The rotation axis Δ 2 of motor is located substantially in the length of the main body 2, so that the motor is in the path of air stream
Direction in orient.In the scope of the utility model, the motor 7 is electronically commutated motor (MCE).
More specifically and as shown in Fig. 2 main body 2 is at least made up of major part 12 and slave part 13.
Major part 12 include decline part 14, that is to say, that the part 14 towards the inside of the main body 2 or in
Centre tilts.As shown in figure 1, the part 14 is at least partially generally circular such as major part 12.In other words, the part is enclosed
Around the rotation axis Δ 2 at least along the angle extension between 10 ° and 300 °.
The part 14 is arranged on below slave part 13.The slave part 13 includes what is rotated along rotation axis Δ 1
Cone 15.The rotation axis Δ 1 is roughly parallel to the rotation axis Δ 2 of motor 7, and this causes cone 15 to be arranged on slave part
13 center.Hereinafter, the cone 15 will be referred to as central rotating cone 15.The top of the cone 15 is towards main body 2
Inner orientation.By this way, cone 15 is positioned at least partially inside and the centre of the part 14 of major part 12.
By this way, major part 12 and slave part 13 form the auxiliary towards the externally ported 9 discharge air
Exhaust manifolds 8.Therefore, the major part 12 (including part 14) includes the first wall 16, and first wall 16 corresponds to auxiliary
The surface of exhaust manifolds 8, air extrusion is on a surface to discharge.In an identical manner, slave part 13 includes the second wall
17, second wall 17 corresponds to the surface of auxiliary exhaust conduit 8, it is necessary to which the air being discharged also extrudes on a surface.More
Accurately, these walls form auxiliary exhaust conduit 8.The auxiliary exhaust conduit 8 includes passage 10, the passage 10 along included in
Angle [alpha] between 120 ° and 200 ° forms kink 11.The kink 11 forms deflector, and the deflector makes to arrange through auxiliary
The air for going out conduit 8 implements almost complete turn to, that is to say, that (or turns along the steering of the angle between 120 ° and 200 °
It is curved).In the scope of the utility model, the steering is carried out around track axis A.As shown in figure 3, track axis A is along main
The part 14 of part 12 is directed.The advantages of steering, is to increase the area with the wall of air streams contact, and therefore increases
The friction of air and wall, this allows the speed of slow down air.Afterwards, the air slowed down reaches outside by auxiliary exhaust conduit 8
Export at 9.This externally ported 9 correspond between major part 12 and slave part 13 along the main body 2 profile formed
Gap.Interval average out to 1cm between described two parts.The interval also can be narrower or wider.
With Fig. 1 and Fig. 2 relatively, externally ported the 9 of the auxiliary discharge conduit 8 surround rotation axis Δ 2 along between 10 °
And the angle extension between 300 °.
As shown in Figure 3 or as shown in figure 1, externally ported 9 form plane P.The plane P corresponds to tangent with main body 2
And it is arranged on the plane P between the outer end at externally ported 9 of the wall of auxiliary exhaust conduit 8.The plane P and auxiliary
The angle beta that discharge conduit 8 is formed between 80 ° and 90 ° each other, so that air carries out vertical turn in discharge conduit 8 is aided in
To.By this way, the air stream is generally perpendicularly discharged relative to the main body 2, and this allows not towards user's
Windstream in direction.
In the scope of the utility model, externally ported the 9 of auxiliary discharge conduit 8 extends along the main body 2.The outside
Outlet 9 extends around the rotation axis Δ 1 of the cone 15 along the angle between 10 ° and 300 °.Of the present utility model
In scope, described externally ported 9 surround rotation axis Δ 1 along 300 ° of angle extension and externally ported 9 face occupied
Product is 16 square centimeters.
