This significantly accelerates air purification speed and efficiency. This structure reduces air purification time and achieves a high purification rate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a detailed description of an ion wind generator positive electrode module and an ion purifier of the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] In the description of the present invention, unless otherwise specified, "plurality" means two or more; the terms "center", "longitudinal", "lateral", "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] like Figure 1 As shown, a positive electrode module of an ion wind generator includes an insulating frame 100 and a metal wire 200 arranged on the insulating frame 100, wherein the metal wire 200 is at least one and is fixed to the insulating frame 100 after being bent; the metal wire 200 is divided into several sections by the insulating frame 100; and the several sections of the metal wire 200 are all within the frame range of the insulating frame 100.

[0035] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, at least one of the metal wires 200 is arranged as at least two parallel straight strips of the metal wires 200, and the two adjacent straight strips of the metal wires 200 are connected to each other. The cross-section of the metal wire 200 is rectangular, and the length direction of the cross-section of the metal wire 200 is perpendicular to the plane formed by the two adjacent frame edges of the insulating frame 100. The width-to-length ratio of the cross-section of the metal wire 200 is 1.0:1.1-1.0:12.0.

[0036] The metal wire 200 is configured as a flat structure, with its thickness perpendicular to the air inlet direction. This structure reduces the working surface, thereby reducing the surface area exposed to oxidation and corrosion, thereby increasing the service life of the metal wire 200. Furthermore, the thinner the metal wire 200, the greater the ion movement speed and the higher the ion collection efficiency.

[0037] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, as a further solution of the present invention, the ratio of the width to the length of the cross section of the metal wire 200 is 1.0:1.7-1.0:12.0. That is, the ratio of the thickness to the width of the metal wire 200 is 1.0:1.7-1.0:12.0.

[0038] like Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown, as a further solution of the present invention, the ratio of the width to the length of the cross section of the metal wire 200 is 1.0:4.5-1.0:12.0. That is, the ratio of the thickness to the width of the metal wire 200 is 1.0:4.5-1.0:12.0.

[0039] Table 1 shows the experimental data of the metal wire 200 with different ratios of thickness to width (ie, ratios of cross-sectional width to length).

[0040] Table 1

[0041] Serial number Thickness:Width (ratio) time Sterilization rate 1 0.9:1.0(1.00:1.1) 15min 71.47％ 2 0.5:0.7(1.00:1.4) 15min 78.37％ 3 0.3:0.5(1.00:1.7) 15min 86.84％ 4 0.3:0.7(1.00:2.3) 15min 91.69％ 5 0.2:0.9(1.00:4.5) 15min 99.97％ 6 0.1:1.2(1.00:12.0) 15min 99.98％

[0042] like Figure 1 As shown, as a further solution of the present invention: the material of the metal wire 200 is hafnium or hafnium alloy.

[0043] The metal wire 200 is made of hafnium or hafnium alloy, which has a better air sterilization effect than conventional tungsten wire.

[0044] First embodiment

[0045] like Figure 1 、 Figure 2 As shown, as a further solution of the present invention: a plurality of winding parts 110 are provided on the insulating frame 100 , the metal wire 200 is bent at the winding parts 110 , and the winding parts 110 are provided on two opposite sides of the insulating frame 100 .

[0046] The winding portion 110 is disposed outside the inner edge of the insulating frame 100. The inner edge here refers to the four sides of the insulating frame 100 facing inward, and the outer edge refers to the outer surface. The winding portion 110 can be understood as a winding post, onto which the metal wire 200 can be wound. Of course, in another embodiment, the winding portion 110 can also be perforated or grooved, through which the metal wire 200 can pass to achieve diversion.

[0047] The winding part 110 is arranged on two opposite sides of the insulating frame 100, one end of the metal wire 200 is fixed on the first winding part 111, and then passes through the second winding part 112, the third winding part 113, and the fourth winding part 114 in sequence. Figure 2 It's easy to see that for every two additional winding sections 110, the metal wire 200 has an additional working section 210. The working section 210 here refers to the portion of the metal wire 200 located within the insulating frame 100, which is used to generate corona charges and form ion wind. Each additional working section 210 is equivalent to adding an additional metal wire 200 to a traditional multi-filament structure.

[0048] Preferably, the positions of the multiple winding parts 110 are corresponding to each other, so that the passing metal wire 200 can remain in a vertical or horizontal state, and each two sections of the working parts 210 are also parallel to each other. In this way, during the operation, the corona charge generated is uniform, and the multiple working parts 210 of the metal wire 200 have little influence on each other. The shape of the installed metal wire 200 is similar to the shape of the level signal diagram.

[0049] Furthermore, each pair of winding portions 110 is considered a group, for example, the first winding portion 111 and the second winding portion 112 are a group, the third winding portion 113 and the fourth winding portion 114 are a group, and so on, with the distance between adjacent groups being equal. Under this premise, a spacing value can be determined based on the width and thickness of the metal wire 200 and the magnitude of the applied voltage to ensure that there is no uneven corona between two adjacent working portions 210, thereby ensuring the air purification effect.

[0050] Second embodiment

[0051] like Figures 3 to 8 As shown, as a further solution of the present invention: the winding portion 110 is located outside the inner edge of the insulating frame 100 .

[0052] As an alternative to Example 1, the insulating frame 100 includes an inner frame 120 and an outer frame 130. The insulating frame 100 is hollow, and the winding portion 110 is disposed within the insulating frame 100. Only the working portion 210 of the metal wire 200 is exposed to the air, while the contact portion with the winding portion 110 is concealed within the insulating frame 100. Because during winding, the density of the metal wire 200 in the winding portion 110 is necessarily greater than that in the working portion 210. The density referred to here refers to the absolute length of the metal wire 200 per unit space. For example, using the winding pole fixing method mentioned in Example 1, the metal wire 200 within a cubic centimeter of space will inevitably be longer than one centimeter after being straightened. During the corona discharge process, the discharge power at each point of this portion of the metal wire 200 may vary, resulting in the possibility of burning or melting the metal wire 200. Furthermore, if a punching and threading method is adopted, the metal wire 200 may have defects at the bend. Under the same voltage, the defective point will preferentially discharge with high power, and there is also the possibility of melting.

[0053] like Figures 3 to 8 As shown, as a further solution of the present invention: the metal wire 200 is wound on the insulating frame 100 .

[0054] The distances L3 = L4 = L5 between two adjacent groups are equal. Under this premise, a spacing value can be determined according to the width and thickness of the metal wire 200 and the magnitude of the applied voltage to ensure that there is no uneven corona between two adjacent working parts 210, thereby ensuring the air purification effect.

[0055] like Figure 4 、 Figure 5 、 Figure 6 As shown, as a further solution of the present invention: the winding portion 110 is arc-shaped, and the metal wire 200 is bent in an arc shape at the winding portion 110 .

[0056] In this embodiment, since the wiring is routed within the insulating frame 100, discharges in the first and second non-working portions 220, 230 of the metal wire 200 can be avoided. Furthermore, a wire trough can be provided to allow for arc-shaped routing of the wires, which can then be decorated by installing a trough cover. Ideally, the bend 110 is an arcuate portion 11a, and the working portion 210 and the first non-working portion 220 connected thereto are tangent at the arcuate portion 11a, meaning that the first non-working portion 220 is a quarter circle. This trough structure eliminates obstructions around the first and second non-working portions 220, 230, preventing defects in the metal wire 200 and reducing the likelihood of the wire 200 fusing.

[0057] like Figures 1 to 9 As shown, an ion purifier includes the ion wind generator positive electrode module described in any of the above solutions.

[0058] like Figure 9 As shown, as a further solution of the present invention: it includes at least two of the above-mentioned ion wind generator positive pole modules, any two frame edges of any one of the above-mentioned insulating frames 100 form a plane parallel to the plane formed by any two frame edges of the other remaining insulating frames 100, and the insulating frames 100 are arranged in a row.

[0059] The solid tip in the figure indicates the direction of air inlet, and the hollow tip indicates the direction of air outlet. Multiple ion wind generator positive electrode modules are assembled in a row to improve air purification efficiency.

[0060] Third embodiment

[0061] like Figure 10 、 Figure 11 As shown, a method different from that of Examples 1 and 2 is employed. The metal wire 200 is directly wound around the insulating frame 100. Grooves are provided on the outer surface of the insulating frame 100, and the metal wire 200 is wound directly through the grooves, similar to the winding method of a kite. It should be noted that the working portions 210 of the metal wire 200 wound in this manner are not parallel to each other, which slightly affects discharge efficiency. However, in terms of production efficiency, it significantly surpasses the previous two examples.

[0062] like Figure 10 、 Figure 11 As shown, as a further solution of the present invention, the insulating frame 100 includes an inner frame 120 and an outer frame 130, the metal wire 200 is wound on the inner frame 120, and the outer frame 130 cooperates with the inner frame 120 so that only the working part 210 of the metal wire 200 is exposed to the air.

[0063] like Figure 10 、 Figure 11As shown, as a further solution of the present invention: the diameter of the metal wire is 0.3-0.8 mm.

[0064] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
