Further, because the diameter of motor is less than 35mm, the ratio of air quantity and motor diameter is greater than 12cfm/mm, and therefore compared with common hand blower, the hand blower in the present invention obtains more powerful airflow effects by the motor of small size.
Below Duct design of the present invention is described in detail, Fig. 2 please be refer again to, along the direction of axis L1, be greater than the flow cross section S3 at air outlet 191 position on blower 19 near the flow cross section S1 in the air channel at air intake 112 position in the rear end of fan 173, and between exhausting 171 inwall and fan hub 1731, form an annular flow face (scheming not mark), ratio on blower 19 between the flow cross section S3 at air outlet 191 position and the flow cross section S2 in annular flow face, aerofoil fan 173 present position is preferably greater than or equal to 0.8, arranging so effectively improves airflow characteristic, improve aspect of blowing efficiency.Fan 173 to air outlet 191 sections of air channels define an outer contour L2 simultaneously, and L1 and L2 defines an angle.Preferably, angle between axis L1 and outer contour L2 is less than 8 degree, and arranging like this is form certain windage because angle is larger to air-flow, and the air flow losses of such wind path wall increases, in blower 19, the loss of the high velocity air of circulation increases, and causes the aspect of blowing efficiency of complete machine to reduce.By the optimization of above two parameters, favourable air current flow situation can be realized and in blower 19, realize the less pressure loss simultaneously, effectively improve aspect of blowing efficiency.
In order to reach enough air outputs, through CFD(computational fluid dynamics at air outlet 191 place) to analyze and test data summary, the air outlet place area that design is larger usually, preferably, the cross-sectional area at air outlet 191 position is set to be greater than 4300mm2.Certainly, along with the increase wind speed of blowing area can decrease, through being set to 4300mm to the preferred air outlet area of practical operation
2to 8000mm
2.
By the optimization of the parameter designing of the battery capacity in the present invention, brshless DC motor, aerofoil fan and the improvement of Duct design, when battery capacity is between 170wh-400wh, the air quantity of hand blower all can reach more than 395cfm, particularly when air quantity is at 430-700cfm, still can meet the working time is greater than 5min.When can ensure that hair-dryer runs with maximum quantity of wind, the ratio of air quantity and input power is more than or equal to 0.7cfm/w, and aspect of blowing efficiency is very significantly improved simultaneously.
Although the present invention with preferred embodiment disclose as above, so itself and be not used to limit the present invention.Persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when being as the criterion depending on those as defined in claim.
