Shown, the utility model provides a kind of hand held cleaner, mainly includes main body and coupled dust suction annex, the main body
Including fuselage 2 and the separator being connected with fuselage 2, the separator is provided with sweep-up pipe 1, for dust suction annex to be connected
In main body.Motor 3 is provided with rear side of the top of the fuselage 1, for the battery bag 7 powered to motor 3 and positioned at fuselage 1 one
The handle 6 of side.The separator includes grade one filter, the secondary filter positioned at grade one filter downstream and dust barrel 8, institute
State grade one filter to connect with sweep-up pipe 1, secondary filter includes multiple two level whirlwind cones 10 being arranged side by side, the two level mistake
Angle α scope between the center line Z of filter and the motor air inlet/outlet axis Y is：90 ° of 0 °≤α ＜.Due to depositing for angle α
Dust Storage Room can be entered by dust guiding tube 19 by the multiple action of centrifugal force, gravity in dust caused by the separation of, two level whirlwind cone 10
82.Dust residue is avoided in two level whirlwind cone 10.Wherein, motor air inlet/outlet axis Y and dust barrel and grade one filter axis X
Perpendicular relation, it is preferred that two level whirlwind cone 10 is in or is partially on motor air inlet/outlet axis Y, simultaneously because angle α
In the presence of effectively shortening motor advancing air air channel, be more beneficial for that air current flow is smooth, be advantageous to the performance release of motor.Meanwhile
The product size of hand held cleaner is effectively reduced, more effectively utilizes product space.
Further, the secondary filter is two level cyclone filter, including is symmetrically set by multiple two level whirlwind cone 10
Put the filter body of composition, the center line Z of the secondary filter is the symmetrical centre of multiple two level whirlwind cones, the rotation
Wind, which is crossed, is provided with two level inner cone 15 in filter cone.The setting of two level whirlwind cone 10, grade one filter is effectively failed to the floating dust of separation,
Filtered again.So as to improve the filtering rank of dust catcher.The operating pressure of filter cotton 11 before motor is significantly reduced, is shown
Work improves the service life of filter cotton 11 before motor.Simultaneously motor is effectively protected to avoid into ash.In order that structure is more
It is compact, it is preferred that dust barrel and grade one filter axis X pass through or partially passed through two level whirlwind cone 10, and said structure effectively contracts
Air channel length between short grade one filter and two level whirlwind cone 10, protects motor performance not damaged by air channel to greatest extent
Lose so that two level whirlwind cone 10 plays more preferable centrifugation.
The secondary filter outlet air end is connected by motor advance airduct 28 with motor 3, and the secondary filter is also set
There is a dust guiding tube 19 connected with dust barrel 8, the dust guiding tube 19 and the junction of dust barrel 8 are two level ash hole 191, the two level ash discharge
Mouth 191 is positioned close to the side of sweep-up pipe 1.In order to reach more preferable pick-up performance, set at the secondary filter outlet air end
There is filter cotton 11 before motor.Its composition form of filter cotton 11 belongs to prior art before motor herein, and filter cotton 11 sets before motor
Put, be to prevent that in extreme circumstances, the dust for still having only a few to remain after the filtering of two level whirlwind cone 10 directly enters with air-flow
Enter motor.Side provided with the sweep-up pipe 1 is the front side of hand held cleaner, and the two level ash hole 191 is located at described one
The front of level ash hole 811.Preferably, grade one filter axis X need not be in concentric with the axle center of dust barrel 8.
Further, grade one filter is integrally disposed in dust barrel 8 by the utility model to solve the deficiencies in the prior art
On, including the grade one filter staving 81 inside the dust barrel is set in, the staving bottom is provided with one-level ash hole 811.Institute
State dust barrel bottom and be provided with bottom 27, the bottom of dust barrel 8 is additionally provided with Dust Storage Room 82, is the space with sandwiched outside staving inside dust barrel.
Grade one filter staving 81 is not directly connected to dust barrel bottom 27, improves the grey capacity of storage to greatest extent for Dust Storage Room 82.
Concentric inside grade one filter staving to be provided with net-filter assembly 9, the net-filter assembly includes filter screen bracket 91 and is arranged on
Filter screen 92 on filter screen bracket, wherein filter screen 92 belong to prior art, its form can be plastic mesh, metal net with
And metal etch net.For the ease of processing and dismounting, what the grade one filter staving 81 was formed in one.In order to prevent because of storage
Grey room 82 is dust-full and blocks one-level ash hole 811, and the one-level ash hole 811 is arranged far from the side of sweep-up pipe 1.In addition,
In order to improve separative efficiency, the one-level ash hole 811 is arranged in the side wall of the staving 81, it is preferred that one-level ash hole
811 upper marginal positions are not higher than the lower edge of net-filter assembly 9.Certainly, one-level ash hole 811 can also be opened in grade one filter
The bottom of staving 81.
With reference to shown in Fig. 3 to Fig. 8, the course of work of the present utility model is such：
When dust catcher works, dust tangentially enters grade one filter, quick rotating separation with air-flow by sweep-up pipe 1.Big portion
Divide the air-flow that dust granule is rotated to throw away grade one filter staving 81 from the centrifugation of one-level ash hole 811 and enter Dust Storage Room 82.By
Belong to vacuum chamber in Dust Storage Room 82, while there is no the air-flow rotated at a high speed in Dust Storage Room 82, dust granule once enters Dust Storage Room
82, it will not can enter grade one filter again, so as to avoid influenceing by-pass filtration effect.Air-flow in grade one filter is after filtering
Into net-filter assembly 9.The dust that air-flow fails effectively to filter through grade one filter, net-filter assembly 9, from the top of net-filter assembly 9
Air outlet enters secondary vacuum chamber 21.It is then tangential to enter the secondary filter for thering are multiple two level whirlwind cones 10 to form.Through two level
After whirlwind cone 10 filters again, dust is entered Dust Storage Room 82 by the multiple action of centrifugal force, gravity by dust guiding tube 19.After filtering
Air-flow pass through motor before filter cotton 11 motor is entered by blast pipe 28.So as to realize the use function of dust catcher.
In summary, the utility model provides a kind of hand held cleaner, effectively shortens motor advancing air air channel, more has
It is smooth beneficial to air current flow, protect motor performance not lost by air channel to greatest extent, it is played more preferable centrifugation, electricity
The performance of machine is fully discharged；Meanwhile product size is effectively reduced, product space is made full use of, greatly improves dust suction effect
Rate.
