In above-mentioned technical proposal, the bending of at least one 90 degree of the exhaust passage.
In above-mentioned technical proposal, outlet air filtration members are equipped at the air outlet, the outlet air filtration members are connected together in institute
It states on the air outlet madial wall of back cover tail end.
In above-mentioned technical proposal, the bottom plate is equipped with slot, is adapted with the bottom of the motor, the slot and electricity
Beam is equipped between machine.
In above-mentioned technical proposal, sealing element is filled between the protecgulum inner wall and the motor air inlet.
Since above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：
1. on the one hand the utility model increases one layer of soundproof effect, in addition by the way that protecgulum and back cover are arranged outside motor
On the one hand previous directly outlet air is changed to the outlet air behind exhaust passage of motor air outlet, uses bending of the general mood stream by exhaust passage,
Slow down wind-force and wind speed, to reduce noise when use；
2. by being arranged air outlet in the lower section of hand-held set handle, can rationally utilize inside hand-held set and handbar
Space, in the case where not increasing the volume of hand-held set itself, the noise reducing mechanism that installation protecgulum is formed with back cover forms one with this
Exhaust passage reduces out wind speed, realizes the effect of noise reduction；
3. adding filtration members at air outlet, outlet air is filtered, further increases pick-up performance, is avoided to outside air
Cause secondary pollution；
4. the utility model is simple in structure, exquisite composition, it is suitble to the use of all kinds of small handheld dust catchers.
