[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] Example:

[0036] Please see Figures 1-5 The multi-ion generator includes: an ion box 1; a PCBA board disposed inside the ion box 1; a positive ion discharge brush 3, one end of which penetrates the ion box 1 and is connected to the positive voltage of the PCBA board, and the other end of which is located outside the ion box 1; and a negative ion discharge brush 4, one end of which penetrates the ion box 1 and is connected to the negative voltage of the PCBA board, and the other end of which is located outside the ion box 1. A gap exists between the negative ion discharge brush 4 and the positive ion discharge brush 3.

[0037] like Figures 1-3As shown. In this embodiment, the multi-ion generator includes an ion box 1, a PCBA board, a positive ion discharge brush 3, and a negative ion discharge brush 4. The PCBA board is disposed inside the ion box 1 and is used to connect to an external high-voltage power source. The bottom end of the positive ion discharge brush 3 penetrates the top of the ion box 1 and is connected to the positive voltage of the PCBA board. The top end of the positive ion discharge brush 3 is located outside the ion box 1. When a high-voltage power source is applied to the positive ion discharge brush 3, positive ions will be generated around its top end. The bottom end of the negative ion discharge brush 4 penetrates the top of the ion box 1 and is connected to the negative voltage of the PCBA board. The top end of the negative ion discharge brush 4 is located outside the ion box 1. When a high-voltage power source is applied to the negative ion discharge brush 4, negative ions will be generated around its top end. There is a gap between the negative ion discharge brush 4 and the positive ion discharge brush 3 to avoid the positive and negative ions being too close together, causing a large amount of cancellation between them. Furthermore, the tops of the positive ion discharge brush 3 and the negative ion discharge brush 4 are at different horizontal levels, which also effectively reduces the amount of positive and negative ions canceling each other out. In this invention, when the PCBA board is connected to a high voltage, the outer end of the positive ion discharge brush 3 will generate positive ions, and the outer end of the negative ion discharge brush 4 will generate negative ions. Maintaining a certain distance between the positive ion discharge brush 3 and the negative ion discharge brush 4 effectively reduces the amount of positive and negative ions canceling each other out. The multi-ion generator provided by this invention has diversified ion types, which is beneficial to improving the sterilization and air purification effects.

[0038] Furthermore, the multi-ion generator also includes a conductive water-absorbing rod 5. The bottom end of the conductive water-absorbing rod 5 penetrates the ion box 1 and is connected to the negative voltage of the PCBA board. The top end of the conductive water-absorbing rod 5 is located outside the ion box 1. When the PCBA board is connected to high voltage, the conductive water-absorbing rod 5 will generate water ions at its top end, further diversifying the types of ions.

[0039] Furthermore, the multi-ion generator also includes a plasma emission unit 6, which is disposed inside the ion box 1 and electrically connected at its bottom end to the PCBA board, and at its top end to the outside of the ion box 1. When the PCBA board is connected to high voltage, the plasma emission unit 6 will generate plasma at its top end, further diversifying the types of ions.

[0040] like Figure 4As shown, in this embodiment, the plasma emission unit 6 includes a ground plane 601 and discharge serrations 602. The ground plane 601 is disposed inside the ion box 1 and electrically connected to the grounding wire of the PCBA board. The ground plane 601 has a circular hole 6011, and one side of the ion box 1 has an elongated through hole 1024 opposite to the circular hole 6011. The discharge serrations 602 are disposed inside the ion box 1 and connected to the negative voltage of the PCBA board. The discharge serrations 602 are located below the ground plane 601, and the serration tips 6021 of the discharge serrations 602 correspond to the circular hole 6011.

[0041] Specifically, after a high voltage is applied between the tip 6021 of the discharge sawtooth 602 and the ground plane 601, two electrodes are formed, thereby creating a high voltage electric field. The ground plane 601 has a circular hole 6011 to increase the number of electrode receiving points (inner edge of the circular hole 6011), thereby creating a larger electric field. An ionization discharge or glow discharge channel is formed between the electrodes, and plasma is formed in the surrounding air or gas, thereby triggering a discharge phenomenon.

[0042] Furthermore, the ground plane 601 is provided with a plurality of circular holes 6011, each of which is arranged opposite to the elongated through hole 1024. The discharge saw teeth 602 are provided with a plurality of saw tooth tips 6021, each of which corresponds one-to-one with a circular hole 6011. Specifically, the ground plane 601 has four circular holes 6011, and the discharge saw teeth 602 have four saw tooth tips 6021, each corresponding to one of the four circular holes 6011. The combination of multiple circular holes 6011 and multiple saw tooth tips 6021 increases the number of plasma generated, further improving the sterilization performance of the multi-ion generator.

[0043] Furthermore, the positive ion discharge brush 3, negative ion discharge brush 4, conductive water-absorbing rod 5, and plasma emission unit 6 are arranged in a row at intervals along the length of the ion box 1. Specifically, the ion box 1 is generally rectangular in shape. There are two positive ion discharge brushes 3, which are respectively located at the two ends of the ion box 1 along its length. The plasma emission unit 6 is located in the middle of the ion box 1. There are two negative ion discharge brushes 4, which are respectively located between the positive ion discharge brush 3 and the plasma emission unit 6. There are two conductive water-absorbing rods 5, which are respectively located between the negative ion discharge brush 4 and the plasma emission unit 6.

[0044] In this embodiment, the ion box 1 includes: a base 101 and a cover 102. The base 101 has an opening on its bottom side and a receiving cavity, in which the PCBA board is disposed. The cover 102 is detachably mounted on the top side of the base 101. The cover 102 has a first through hole 1021, a second through hole 1022, and a third through hole 1023. One end of the positive ion discharge brush 3, the negative ion discharge brush 4, and the conductive water-absorbing rod 5 respectively penetrates the top side of the base 101 and is connected to the PCBA board. The other end of the positive ion discharge brush 3 is disposed in the first through hole 1021. The other end of the negative ion discharge brush 4 penetrates the second through hole 1022. The other end of the conductive water-absorbing rod 5 penetrates the third through hole 1023. The ground plate 601 and the discharge serrations 602 are respectively disposed in the cover 102 and penetrate the top side of the base 101 and are connected to the PCBA board.

[0045] Specifically, the bottom end of the positive ion discharge brush 3 penetrates the top side of the base 101 and is connected to the PCBA board, and the top end of the positive ion discharge brush 3 is located in the first through hole 1021; the bottom end of the negative ion discharge brush 4 penetrates the top side of the base 101 and is connected to the PCBA board, and the top end of the negative ion discharge brush 4 extends out of the cover 102 through the second through hole 1022; the bottom end of the conductive water-absorbing rod 5 penetrates the top side of the base 101 and is connected to the PCBA board, and the top end of the conductive water-absorbing rod 5 extends out of the cover 102 through the third through hole 1023; the grounding plate 601 and the discharge saw teeth 602 are respectively disposed between the top side of the cover 102 and the base 101, the bottom ends of the grounding plate 601 and the discharge saw teeth 602 respectively penetrate the top side of the base 101 and are connected to the PCBA board, and the top of the grounding plate 601 is close to the elongated through hole 1024 of the cover 102. The cover 102 and the base 101 are detachably connected to facilitate the disassembly and assembly of the ion box 1, and both the base 101 and the cover 102 in this embodiment are made of plastic.

[0046] Furthermore, the outer side of the base 101 is provided with a buckle 1011, and the outer side of the cover 102 is provided with a latch 1025, the buckle 1011 and the latch 1025 engaging. Specifically, the latch 1025 is an elastic latch, and the side plate of the cover 102 has a certain elasticity, so as to facilitate engagement with the base 101 through the cooperation of the buckle 1011 and the latch 1025.

[0047] Furthermore, the bottom side of the base 101 is provided with potting compound 7, and the penetration joints of the positive ion discharge brush 3, negative ion discharge brush 4, conductive water-absorbing rod 5, ground plane 601, and discharge serrations 602 with the base 101 are also provided with potting compound 7. The potting compound 7 can fix the PCBA board, positive ion discharge brush 3, negative ion discharge brush 4, conductive water-absorbing rod 5, ground plane 601, and discharge serrations 602, enhancing the internal structural stability of the multi-ion generator, and the potting compound 7 also serves as insulation.

[0048] like Figure 5 As shown, in this embodiment, multiple insulators 8 are provided within the ion box 1. The positive ion discharge brush 3, negative ion discharge brush 4, conductive water-absorbing rod 5, and plasma emission unit 6 are each separated by an insulator 8. Specifically, the insulators 8 separate the positive ion discharge brush 3, negative ion discharge brush 4, conductive water-absorbing rod 5, and plasma emission unit 6, ensuring that each generates an independent corona discharge region in its surrounding space, thus avoiding disordered electric field intensity distribution. The insulators 8 also enhance the sterilization and air purification performance of the multi-ion generator.

[0049] In summary, this utility model provides a multi-ion generator, comprising: an ion box 1; a PCBA board disposed within the ion box 1; a positive ion discharge brush 3, one end of which penetrates the ion box 1 and is connected to the PCBA board with a positive voltage, and the other end located outside the ion box 1; and a negative ion discharge brush 4, one end of which penetrates the ion box 1 and is connected to the PCBA board with a negative voltage, and the other end located outside the ion box 1. A gap exists between the negative ion discharge brush 4 and the positive ion discharge brush 3. In this utility model, when the PCBA board is connected to a high voltage, the outer end of the positive ion discharge brush 3 will generate positive ions, and the outer end of the negative ion discharge brush 4 will generate negative ions. Maintaining a certain gap between the positive ion discharge brush 3 and the negative ion discharge brush 4 effectively reduces the amount of positive and negative ions canceling each other out. The multi-ion generator provided by this utility model offers a diverse range of ion types, which is beneficial for improving sterilization and air purification effects.
