The specific embodiment
As shown in Figure 2, ionization part 10 is arranged at the forward part of air purifier, and when connecting high voltage, makes foreign substances 40 such as airborne dust carry out ionization.The structure of ionizing part 10 can constitute another electrode (sparking electrode) that is provided with by an electrode (sparking electrode) with above-mentioned electrode surface, but there is no particular limitation to its shape or size.In order to enlarge the ionized space of ionizing part, can be with the some formation coil shapes in above-mentioned sparking electrode and the counter electrode, and make another constitute plate shape or aperture plate shape, perhaps can make two electrodes all constitute coil shape.Wherein, connect high voltage by power supply unit 30 in the ionizing part 10.
Also static flocking fibre can be set on the electrode of ionizing part 10, in the case, foreign substances is in the process of carrying out ionization, and the fiber by above-mentioned flocking carries out 1 filter operation.
And, can add that after ionizing part 10 after-filter 21 being set, can use the electrode of aperture plate shape as above-mentioned after-filter 21, it is preferably pasted from the teeth outwards static flocking fibre is set.The above-mentioned after-filter 21 that is pasted with static flocking fibre is when connecting high voltage, and its static flocking fibre filters dust by electrostatic interaction.
In addition, dust collecting part 20 is made of an electrode 22 at least, preferably pastes the fiber 23 that electrostatic spinning is set in the above-mentioned electrode 22.Connect high voltage on the above-mentioned dust collecting part 20, obtain ionization and move to dust 41 of dust collecting part 20 etc., be adsorbed in the above-mentioned static flocking fibre 23 by electrostatic force by ionizing part 10.Above-mentioned static flocking fibre 23 also can adsorb dust etc. by physics mode except by the suction-operated of electrostatic force, and strengthens filter effect.Consequently, obtain comprising hardly in the filtered air particle 42 foreign substances such as dust.
And, the electrode 22 of above-mentioned dust collecting part is the electrode of aperture plate (mesh) shape preferably, and the electrode of above-mentioned aperture plate shape can form static flocking fibre easily in its surface, and, because it has through hole, thereby the air of removing dust etc. is flowed easily.
As Fig. 2, shown in Figure 3, be adsorbed with dust particle 41 on the static flocking fibre 23, at this moment, utilize the split pole row of the fiber of electrostatic spinning to carry out the dust filter operation to (polarization orientation) characteristic.
Below, with reference to Fig. 4, the split pole of static flocking fibre is arranged to describing.As shown in Figure 4, between two electrodes 51,52 of plate shape the fiber 53 that needs flocking is set, when connecting voltage in electrode, the split pole row who produces fiber under the effect of electrostatic force is to (B), and the fiber 54 of split pole will move, and towards circuit board 60.Wherein, be pre-formed adhesive layer 61 on the surface of foregoing circuit plate 60, thereby above-mentioned mobile fiber 55 is fixed.
Consult again shown in Figure 5 since the static flocking fibre of pasting on the circuit board 60 55 be in split pole row to state, and can continue its split pole state of maintenance by outside electric power.Under above-mentioned split pole state, can adsorb particles such as above-mentioned Ionized dust by electrostatic interaction.Fig. 6 is the actual schematic diagram that static flocking fibre is set on the grid electrode surface uniformly.
In air purifier of the present invention, static flocking fibre filters dust etc. by electrostatic means, simultaneously, and by physics contact filtration dust etc.Therefore, it is particularly important to control the shape of above-mentioned static flocking fibre.
When thicker or length is longer when static flocking fibre, can improve physics contact effect.And,, can obtain the difference of discharge current characteristic as shown in table 1 below according to the length of static flocking fibre.
[table 1] is according to the discharge current characteristic of static flocking fibre length
