Description
Technical field
The present invention relates to portable vacuum device or portable blower/vacuum plant.
Background technology
In traditional portable vacuum device or air blast/vacuum plant, dust that is collected or fragment are inhaled into and finally by being positioned at the fan with the rectangular position of direction of air flow tube along the cleaning pipe.Fig. 1 is illustrated in the example of traditional vacuum device or air blast/vacuum plant.This device has the fan 1 that rotates by the motor driving.Dust or fragment suck from the end of cleaning pipe 2 by fan 1 and the suction inlet 3 by fan 1, and drain in the dust-collector 5 (in this case, being the textile bags that can see through air) from outlet 4.Dust is collected in this gatherer and air is discharged into the atmosphere by the fabric of this gatherer.Dust or fragment enter dust-collector 5 by fan from the end suction of cleaning pipe 2 and by fan 1.
Top setting can be very effective for collecting dust and other little particle, but the cleaning shortcoming that it has is, fragment may collect on the blade of fan or collect in the fan drum in use, thereby has reduced efficient or damaged fan or fan drum.And fan may particularly those may not damage by the bottle or the iron flask of fan owing to the fragment of some large-size.This can also exert pressure on fan drum, thereby causes fan drum to split or break.
A kind of mode that overcomes this problem is to use mesh screen.In another embodiment of the vacuum plant that is shown in Fig. 2 or air blast/vacuum plant, the dust or the fragment that suck from cleaning pipe 2 ends are collected by mesh screen 6.Air is inhaled into the suction inlet 3 by fan 1 subsequently, passes this fan 1 and discharges into the atmosphere via outlet 4.Although this set can prevent bigger fragment by fan, mesh screen can block the fragment of large-size.This has also applied pressure on fan drum, thereby causes fan drum to split or break.
A kind of substitute mode that overcomes this problem is to use convergence tube.Fig. 3 shows a kind of known dust-collector, and wherein fan 1 has the outlet 4 that is communicated with air hose 7.Drive and the fan 1 generation air blast of rotation by motor.Flow through air hose 7 and convergence tube 8 from the air blast of fan 1 and enter into gatherer 5.In convergence tube 8, air blast is incorporated into air in the gatherer 5 from cleaning pipe 2.Although this set has been avoided near the obstruction of the fragment the fan, this makes and more is difficult to produce suction enough or same level.Although can make adjusting increasing suction to motor and fan, such its efficient is lower and tend to produce heavier and/or heavier device.
Any reference to prior art does not constitute and should not be considered to be in Australia or any other country has constituted the part of common practise in this specification.
