The work of this embodiment of explanation below.In case through being arranged on the switch connection power supply on the grip part 6, then main motor and primary heater 22 are worked, outer gas is directed in the primary air stream 12, and discharges by heater 22 heating and from main outlet 10.In addition, through the work of the secondary electric blowing machine 34 in the secondary air flow circuit 24, outer gas flow into secondary air flow circuit 24 and flows along the top and bottom of the substrate 38 of electrostatic atomization apparatus 36.Flow to air cooling on the upper surface of substrate 38 as the heat liberation board 52 that Po Er pastes the heat release portion of element 50, flow to the outside from secondary outlet 28.

Along the lower surface flow air of substrate 38, flow from the peristome 60 of sparking electrode 44, and flow to secondary outlet 28 towards the shaft-like electric conductor 54 that pastes element 50 coolings by Po Er, comparative electrode 58.The airborne water vapour that flows into from the outside contacts and condensation with the electric conductor 54 of cooling, and on the surface of electric conductor 54, condenses.This dewfall and water (condensate) descend by the gravity effect, flow to the lower end of electric conductor 54.

On the other hand, owing to be added with high voltage outward between sparking electrode 44 and comparative electrode 58, so close gap formation highfield that can setting between the front end of sparking electrode 44 and comparative electrode 58.On the electric conductor 54 in this electric field, between position that sparking electrode 44 faces toward and the front end relative, produce charge inducing, between relative sparking electrode 44 of close gap and electric conductor 54, producing discharge (corona discharge) with comparative electrode 58.Thereby, can form highfield across big gap between the inner peripheral of the peristome 60 of the front end of relative electric conductor 54 and comparative electrode 58.This electric field concentrates on the front end of electric conductor 54, thereby electric field density (electric-field intensity) enlarges markedly.

The water droplet that the result is present in the lower end of electric conductor 54 produces charge inducing, if be created in the surface tension that the tensile force at the two ends of water droplet surpasses water droplet, then water droplet division (electrostatic atomization, Rayleigh division) by electric field.Consequently, the water droplet atomizing, the small water droplet that has negative electricity (ionization) is run fast towards the opening 60 of comparative electrode 58.The wind that secondary electric blowing machine 34 causes is transported this Ionized small water droplet to the outside from secondary outlet 28, and together discharges with the warm braw of discharging from main outlet 10.In addition, division, other the small water droplet that has positive electricity neutralizes electrostatic atomization once more attached to the front end of electric conductor 54.

The air mass flow (air quantity) that flows in the secondary air flow circuit 24 is irrelevant with the air quantity variation of primary air stream 12, can be certain all the time, in this case, can be set at the air quantity that makes electrostatic atomization apparatus produce the small water droplet of ionization most effectively.In addition; The rotary speed of secondary electric blowing machine 34 can through be arranged on the grip part 6 switch (not shown) by stages, or adjustment continuously; The air quantity of secondary air flow circuit 24 is changed, for example, the rotary speed of secondary electric blowing machine 34 is changed through manual operation.In addition, can be to be accompanied by through being arranged on the air quantity that switch on the grip part 6 switches main electric blowing machine, change the air quantity of secondary electric blowing machine 34 automatically; Also can stop main electric blowing machine, only make secondary electric blowing machine 34 work discharge Ionized small water droplet.

Through changing the air quantity of secondary electric blowing machine 34; Thereby can change the ionic weight or the ion concentration that in electrostatic atomization apparatus 36, produce, the result can change whole total ionic weight, ion concentration that contains the wind of discharging of discharging from secondary air flow circuit 24 and primary air stream 12.
