[0026] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.
[0027] The first embodiment mainly sees Figure 1 and Figure 2 The present application discloses a dielectric barrier discharge ion generator (hereinafter referred to as "ion generator"), comprising a flat dielectric barrier discharge unit 1 and a first insulating terminal 2 having a first assembly groove 21, wherein one of the short sides of the discharge unit 1 is an electrode terminal, and the electrode terminal is inserted into the first assembly groove 21; and further comprising: two long edge sealing members 3, wherein the long edge sealing member 3 comprises an edge sealing body 31 located on the vertical side of the long side of the discharge unit 1 and a limiting portion 32 extending from the edge sealing body 31 and pressing the upper and lower surfaces of the long side of the discharge unit 1, wherein the two opposite long sides of the discharge unit 1 Respectively inserted into the limiting parts 32 on the upper and lower sides of the long edge sealing member 3; the assembly part is arranged on the other short side of the discharge unit 1 opposite to the electrode end, the assembly part is a short edge sealing member 4, and the short edge sealing member 4 and the long edge sealing member 3 are an integral structure; the same ends of the two long edge sealing members 3 are respectively connected with the first assembly groove 21 in a limiting manner; wherein the electrode end has a first terminal 111 and a second terminal 131, and the first terminal 111 and the second terminal 131 respectively pass through the first assembly groove 21 and extend out of the first insulating terminal 2.
[0028] The same end of the long edge sealing member 3 is usually connected to the first assembly groove 21 by interference fit, or by gluing, adhesive tape or the like.
[0029] By limiting and assembling the same end of the two long edge sealing members 3 and the first assembly groove 21 of the first insulating terminal 2, the two long edge sealing members 3 are limited and fixed by using the first assembly groove 21, so that the four sides of the flat discharge unit 1 are packaged and fixed by using the two long edge sealing members 3, the short edge sealing member 4 and the first insulating terminal 2, which can not only make the side edges of the discharge unit 1 waterproof and isolate, but also avoid interlayer movement between the layers of the discharge unit 1 by limiting and fixing the four sides of the discharge unit 1, thereby maintaining a stable and reliable dielectric barrier discharge structure, thereby improving the reliability of the ion generator.
[0030] At the same time, since the two long edge sealing members 3 and the short edge sealing member 4 are an integrated structure, and the first terminal 111 and the second terminal 131 are both arranged at the electrode end of the discharge unit 1, the assembly process is simplified compared with the prior art, and the assembly is convenient.
[0031] Furthermore, considering that the ion generator is usually installed at the air outlet of products such as air conditioners and fans, the first insulating terminal 2 is used as a fixing seat of the ion generator to fix the ion generator upright at the air outlet. This not only facilitates the routing of the first terminal 111 and the second terminal 131 and the high-voltage circuit used in conjunction with them, but also reduces the obstruction of the surface of the discharge unit 1 and improves the working performance of the ion generator.
[0032] Of course, a buckle can also be provided on the groove wall of the first assembly groove 21, and the edge sealing body 31 is correspondingly provided with a buckle position 33, and the buckle position 33 is buckled and cooperated with the buckle to further improve the structural reliability of the limited assembly between the ends of the two long edge sealing pieces 3 and the first insulating terminal 2.
[0033] In the illustrated embodiment, the overall cross-section of the long edge sealing member 3 is a U-shaped structure, and the limiting portion 32 is in a strip shape as a whole, preferably formed by bending or forming two opposite sides of the edge sealing body 31 toward the same side. Of course, the limiting portion 32 is not limited to being in a strip shape, but can also be in a point shape, and a plurality of point-shaped limiting portions 32 are used to press and limit the upper and lower surfaces of the long side of the discharge unit 1.
[0034] The thickness of the limiting portion 32 does not exceed 2 mm. By setting the limiting portion 32 to have a smaller thickness, the blocking effect of the limiting portion 32 on the ion release from the surface of the discharge unit 1 is reduced.
[0035] The long edge sealing member 3 is usually made of hard metal, and the thickness of the limiting portion 32 is preferably between 0.2 mm and 0.5 mm. Of course, the long edge sealing member 3 can also be made of plastic, and the thickness of the limiting portion 32 is preferably no more than 1.5 mm.
[0036] The second embodiment mainly sees Figure 3 and Figure 4 The second embodiment is based on the first embodiment, the assembly further comprises a second insulating terminal 5, the second insulating terminal 5 has a second assembly groove, and the other short side of the discharge unit 1 relative to the electrode end is inserted into the second assembly groove for limited assembly.
[0037] In this embodiment, the second insulating terminal 5 can be used as a component selected by the user as needed. The main purpose of setting the second insulating terminal 5 is to consider that in some actual use scenarios, due to the limited height of the air outlet of products such as air conditioners and fans, the ion generator needs to be fixed horizontally, so the first insulating terminal 1 and the second insulating terminal 5 can be used as the fixing seat or fixed support position of the ion generator for horizontal assembly, so as to facilitate user use.
[0038] The third embodiment mainly shows Figure 5 and Figure 6 As shown. Based on the second embodiment, considering that the same ends of the two long edge seals 3 can also be fixed by the second insulating terminal 5, the short edge seal 4 is omitted, that is, the assembly only includes the second insulating terminal 5. Among them, the same ends of the two long edge seals 3 and the second assembly groove of the second insulating terminal 5 are also fixed by interference fit or bonding.
[0039] In addition, the second assembly groove is also provided with a buckle, and the edge sealing body 31 is correspondingly provided with a buckle position 33, and the buckle position 33 is buckled and cooperated with the buckle to further improve the structural reliability of the limited assembly between the ends of the two long edge sealing members 3 and the second insulating terminal 5.
[0040] The discharge unit 1 can adopt any existing dielectric barrier discharge structure. Figure 7 The figure shows a typical dielectric barrier discharge structure, wherein the discharge unit comprises the discharge unit 1, which comprises a metal inner electrode plate 11, a metal outer electrode plate 13 separated from two side surfaces of the metal inner electrode plate 11, and an insulating dielectric plate 12 located between the metal outer electrode plate 13 and the metal inner electrode plate 11, wherein the first terminal 111 and the second terminal 131 extend from the metal inner electrode plate 11 and the metal outer electrode plate 13, respectively.
[0041] The metal inner electrode plate 11 is electrically connected to the output end of the high-voltage circuit used in conjunction with the discharge unit 1 through the first terminal 111, and the second terminal 131 of the metal outer electrode plate 13 is grounded, forming a high-voltage electric field between the metal inner electrode plate 11 and the metal outer electrode plate 13, and the insulating dielectric plate 12 is located in the high-voltage electric field to form a dielectric barrier discharge, so that the surface of the metal outer electrode plate 13 ionizes the air into positive and negative ions, and the ions are released into the air to achieve air purification and sterilization.
[0042] The fourth embodiment mainly shows Figure 8 and Fig. 9As shown. Based on the first, second and third embodiments, the limiting portion 32 is provided with a protrusion 35 on the inner side of the discharge unit 1, and the surface of the discharge unit 1 is provided with a limiting groove 132, that is, a limiting groove 132 is provided on the long side of the metal outer pole plate 13 corresponding to the protrusion 35, and the protrusion 35 is limitedly matched with the limiting groove 132. Such a structure can form a limiting matching structure between the limiting portion 32 and the long side of the metal outer pole plate 13, reduce the limiting assembly requirements of the same end of the two long edge sealing members 3 using the first insulating terminal 2 and / or the second insulating terminal 5, and is also conducive to improving the overall structural reliability of the ion generator.
[0043] The fifth embodiment mainly shows Fig.10 As shown. On the basis of the first to fourth embodiments, the insulating dielectric plate 12 is provided with a groove 121 of depth L1 at the position corresponding to the position of the limiting portion 32 on the long side surface facing the metal outer pole plate 13, and the metal outer pole plate 13 forms an inner concave portion 133 of depth L2 at the position corresponding to the groove 121, L1≥L2≥thickness L3 of the limiting portion 32; the limiting portion 32 is located in the inner concave portion 133, and the surface of the limiting portion 32 is not higher than the surface of the metal outer pole plate 13. With such a structure, the limiting portion 32 of the long edge sealing member 3 can be used to limit the long side of the discharge unit 1, and at the same time, the surface of the limiting portion 32 is not higher than the surface of the metal outer pole plate 13, so that the limiting portion 32 will not block the positive and negative ions generated on the surface of the metal outer pole plate 13 from being released into the surrounding air, thereby helping to improve the working performance of the ion generator.
[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
