Description of the Invention: [Technical Field] The present invention relates to a cleaning device, and more particularly to a screen device for an air cleaner capable of filtering suspended particles in air. [Prior Art] One of the common air cleaning methods at present is to use an Electro-Static Precipitator (ESP) to purify air, which uses a Corona Discharge principle to apply a high-voltage power supply between the two electrodes to generate a powerful The electric field, and thus the insulating properties of the air, causes the suspended particles in the air to be positively charged, and the suspended particles can be adsorbed and collected on the dust collecting plate. Another method of air purification is to use a negative ion generator, which combines suspended particles with negative ions to reduce the characteristics of suspended particles to the ground and no longer suspend, thus achieving the purpose of purifying the air. Another way to clean the air is to direct the airflow through a fiber or metal mesh that is covered with holes of various sizes, and then filter the suspended particles of different sizes. Conventional air cleaners use woven fabric as the filter material for suspended particles. They use fine-grained glass fiber or melt-blown organic fiber and increase the filtration efficiency by increasing the fineness or high basis weight, but when the efficiency is improved Relatively, the pressure loss is increased, resulting in an increase in energy power, and the cost of the filter screen is also high, so that the consumer's willingness to purchase an air cleaner or update the filter is also reduced. Another design of the traditional air purifier 'mainly emphasizes the static 1297280 electric dust collection design without consumables. Although it has the characteristics of low power and low consumables, the filtration efficiency is limited, such as for sub-micron dust or high air volume operation. The environment, and the filtering performance of the other ESP is still degraded. In recent years, another new design widely used in air purifiers is the use of electrostatic filters, which use high-efficiency filters for fiber charging treatment, improve the electrostatic effect of the filtration mechanism, and then sweep the air with high pressure and high efficiency. The market, but the attenuation of its electrostatic effect is very fast, resulting in an increase in the replacement rate of consumables. Similarly, the price of the filter is also high. U.S. Patent No. 5,474, 599 discloses an electrostatic air cleaner, and Figure 1 is a schematic view of a conventional electrostatic air cleaner. The ionizer 11 has a plurality of metal plates 112 that are no longer electrically grounded, and a plurality of high-voltage discharge lines 114. After the high-voltage discharge lines 114 are discharged, the suspended particles of the air flow 10 are polarized and positively charged, and thus have conductivity. Or the semi-conductive grids 12, 14 allow the aerosol to flow in the vertical direction of the grids 12, 14 without irregular fluttering, while the filter media 13, 15 are made of special and expensive polyethers. Made up of Polyether Foam, which can be used to filter suspended particles. However, when a special sponge is used as the filter medium, the cost of the sponge replacement replacement is too high and is not economical. SUMMARY OF THE INVENTION In view of this, before the high purification efficiency is maintained, in order to save energy and reduce the cost of filter replacement, the present invention provides a filter device for an air cleaner, the main purpose of which is to first make it in the air. The suspended particles produced chargeability, and then the charged suspension in the trapped air with high filtration efficiency was 1,297,280 particles. Through the filter with multi-fold surface, the contact area between the filter itself and the charged suspended particles can be increased to absorb a large amount of charged aerosols, thereby improving the overall filtration efficiency. In addition, the filter itself does not need to be made of special and expensive materials, so the replacement cost of the filter can be greatly reduced. Another object of the present invention is to replace a screen having an excessively high weaving density with a screen structure having a multi-folded surface, thereby avoiding the problem of high pressure loss caused by a screen having an excessively high density. In the case of low pressure loss, the penetration speed of the flowing air through the filter can be reduced, so that the power required to flow the air can be reduced, thereby achieving the effect of energy saving. Another object of the present invention is to further provide negative ions to increase the concentration of negative ions in the air after filtering the suspended particles in the air, so that the aqueous positive ions, bacteria and dust remaining in the air can be combined with the negative ions to achieve dehumidification. , sterilization and purification of air. In order to achieve the above object, the present invention provides a filter device for an air cleaner comprising an ionization unit and at least one filter layer, the ionization unit ionizing suspended particles in the air; the filter layer has A multi-fold surface for the passage of ionized aerosols. Wherein, the filter device of the air cleaner further comprises an negative ion generator, an air driver and a screen frame, the negative ion generator is for providing negative ions; the air driver is for driving air flow; the filter The frame is used to secure the screen layer and to have a multi-fold surface. Preferably, the multi-folded surface of the screen layer has a continuous wave shape or a continuous zigzag shape, and may be made of a glass fiber material, a non-woven fiber material or a melt-blown organic fiber material. The ionization unit is composed of a plurality of conductive wires, conductive strips or conductive plates or consists of a non-woven material 7 1297280 having electrical conductivity. Preferably, the filter device of the air cleaner further comprises at least one conductive layer, the conductive layer may be staggered with the filter layer, or may be attached to the filter layer, and the conductive layer may be electrically conductive.

The simplified schematic structure, when the high-voltage conductive line 222 is discharged, through the grounding line and the related arrangement of the insulating material, the frame 221 is not charged, and only the ionized region is formed around the high-voltage conductive line 222, so that the air flow 20 is suspended. It will be polarized and positively charged, and the special design of the filter layer 23 will effectively filter the suspended particles in the air. The embodiment of the conductive wire 222 is not limited to a line shape, and may be strip or plate shape to increase the range of the ionization region. The ionization unit 22 can also be a conductive non-woven fabric layer (Nonwovens). Instead of the high voltage conductive line 222, the use of the high voltage conductive line 222 is replaced.
