Specific embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
It as shown in Figure 1 and Figure 2, is a kind of first embodiment of hand-held radio dust catcher provided by the invention, the dust catcher
It include: air inlet pipe 1, dust pocket 2 and electric machine assembly.Air inlet pipe 1 is set to the left side of dust pocket 2, and electric machine assembly is placed in the dust pocket right side
Side, the two are co-axially mounted.Dust arrester is coaxially provided with separator 7 and wind wheel 8 in 2 inner cavity.The electric machine assembly includes: electric machine assembly shell
Body 3, built-in motor 9, the power supply 10 with electrical connection of motor.Power supply can use various batteries, such as, common batteries, lithium electricity
Pond or rechargeable battery etc..The output shaft of motor 9 is connect with wind wheel 8, and electric machine assembly shell 3 uses two sections of split settings, wherein
Battery, motor is respectively set, electric machine assembly shell 3 can also be wholely set.The electric machine assembly shell 3 is equipped with exhaust outlet 4,
The exhaust outlet 4 as needed can be set to the arbitrarily reasonable position of 3 wall body of electric machine assembly shell.Air inlet pipe 1 is parallel to dust arrester 2
Axis, and be set to integrator 2 outer circle on, 1 rear end tube wall of air inlet pipe be equipped with gas outlet 11, which is obliquely installed can
So that circumference tangential admission of the gas dirt of sucking along separator 7, the gas dirt tangentially entered directly can do cyclone point around separator 7
From helping to improve the separating effect of gas dirt.In the present embodiment, to use convenient for dust catcher, air inlet pipe 1 is set to integrator 2
