Description of drawings: Fig. 1 is the assembly figure of pocket powerful dust catcher, and Fig. 2 is a right side cross-sectional view.Wherein: 1 be dust absorption nozzle, 2 for capping, 3 for fan, 4 for dust-absorbing element, 5 for clamp long spiro nail, 6 for motor, 7 for the fixed electrical machinery pressing plate, 8 for the fixed electrical machinery screw, 9 for transformer, 10 for the dust collector upper cover hold-down screw, 11 for the rectification circuit plate, 12 for dust collector upper cover, 13 for the dust storehouse cover lock, 14 for attaching plug, 15 for the dust storehouse lid, 16 for power switch, 17 for dirt filtrating screen, 18 for cloudy notch, 19 be suction port.

A most preferred embodiment of the present utility model:

As shown in Figure 1 and Figure 2, pocket powerful dust catcher is made up of capping 2, fan 3, dust-absorbing element 4, motor 6, transformer 9, rectification circuit plate 11, dust collector upper cover 12, attaching plug 14, dust storehouse lid 15, power switch 16, dirt filtrating screen 17 etc.Transformer 9, rectification circuit plate 11, power switch 16 are positioned at the middle part of dust catcher and extend to the rear portion, by the molding space clamping and positioning between dust-absorbing element 4 and the dust collector upper cover 12.Pinching screw 10 has two.Motor 6 is positioned at the front portion of this molding space.Fixed electrical machinery pressing plate 7 is pressed on the motor 6, motor 6 is fixed on the dust suction gas 4 through fixed electrical machinery pressing plate 7 by two fixed electrical machinery screws 8.The main shaft of motor 6 passes from the hole on the dust-absorbing element 4.The main shaft interference fit of the centre bore of fan 3 and motor 6.The two sides of dust-absorbing element fan 3 one sides are the groove shape of reverse U shape, have venthole on it, and its medial surface posts dirt filtrating screen 17.Two end inboards, limit of U font have cloudy notch 18.There is a small embossment rear end of dust storehouse lid 15L plate.This small embossment matches with convex dust storehouse cover lock 13 on the relevant position, dust catcher gas 4 rear end, is locked after dust storehouse lid 15 is inserted, and has venthole on the dust storehouse lid 15, and is identical with the venthole at position, dust-absorbing element U-shaped both sides.Same dirt filtrating screen 17 is posted in its inboard.Have the rim of the mouth on the edge of the dust catcher gas 4 of fan 3 one sides.Have the rim of the mouth that cooperates with it in the capping 2.Capping 2 lids in the above, and are by two clamping long spiro nails 5 that capping 2, dust-absorbing element 4 and dust collector upper cover 12 is fastening in the lump.Other has a short screw that capping 2 is fastened on the dust-absorbing element 4.The bottom of capping 2 is circular dust catcher mouths 19.The top of dust absorption nozzle 1 is cylindrical.Insert in the suction port 19, with dust catcher mouth 19 interference fit on the top of dust absorption nozzle 1.Dust absorption nozzle 1 has a plurality of that terminal end shape has nothing in common with each other.Be its do not hold flat, hairbrush shape or the like.Connect by lead between motor 6, transformer 9, rectification circuit plate 11, power switch 16, the attaching plug 14.The lead of attaching plug 14 is drawn from the rear portion of dust-absorbing element 4.

The utility model in pocket powerful dust catcher product the suction maximum, operating efficiency is the highest and need not to change battery, thereby use cost is also the cheapest, and is converted into practical by toy-type.
