[0045] The embodiments of this application 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 application, and should not be construed as limiting this application.
[0046] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art: Existing tubular plasma tubes typically have an inner electrode-insulating dielectric layer-outer electrode structure, consisting of an outer electrode mesh, an inner electrode mesh, and an intermediate dielectric quartz glass tube assembled together by fasteners to form a plasma tube assembly. However, a single plasma tube cannot cover the entire air outlet, and the plasma cannot fully mix and react with the air, resulting in poor air purification performance.
[0047] The following is for reference. Figures 1-10 This application describes a plasma tube assembly and an air purifier according to embodiments thereof.
[0048] like Figure 1 and Figure 2As shown, a plasma tube assembly, installed at an air outlet, includes: a mounting frame 100, an insulating dielectric tube 200, a first conductive wire 310, and a second conductive wire 320.
[0049] The mounting frame 100 has ventilation holes 110, which correspond to air vents. Several fixing through holes 121 are provided on opposite sides of the ventilation holes 110. A first conductive wire 310 and a second conductive wire 320 are fixed in two adjacent insulating dielectric tubes 200, respectively. Several first conductive wires 310 are connected to the positive terminal of the power supply, and several second conductive wires 320 are connected to the negative terminal of the power supply.
[0050] The insulating medium tube 200 is inserted into the fixed through hole 121 and installed at intervals in the ventilation hole 110.
[0051] In actual implementation, there are multiple first conductive wires 310 and second conductive wires 320, and the first conductive wires 310 and second conductive wires 320 are arranged alternately along the length of the ventilation hole 110. Multiple first conductive wires 310 are electrically connected to each other; multiple second conductive wires 320 are electrically connected to each other. It should be noted that each first conductive wire 310 and each second conductive wire 320 is covered with an insulating dielectric tube 200, and a gap for air to pass through is formed between each two adjacent insulating dielectric tubes 200.
[0052] Multiple interconnected first conductive wires 310 and multiple interconnected second conductive wires 320 can be connected to an AC high-voltage power supply. The first conductive wires 310 and the second conductive wires 320 will alternate as positive and negative poles, and an alternating electric field will be formed between the first conductive wires 310 and the second conductive wires 320.
[0053] The ambient gas flows through the gap between the insulating dielectric tubes 200, and under the action of a high-intensity electric field, some gas molecules are excited to the ionized state, forming plasma. The active particles in the plasma can react with pollutants in the ambient gas (such as bacteria, viruses, volatile organic compounds, etc.), destroy their molecular structure, and degrade them into harmless substances (such as water and carbon dioxide).
[0054] In the above embodiments of this application, through the tube-to-tube arrangement structure, the plasma tube covers the air outlet, and each conductive wire is covered with an insulating dielectric tube 200. After the first conductive wire 310 and the second conductive wire 320 are energized, the electric field between adjacent conductive wires passes through the walls of the two insulating dielectric tubes 200, and the dual dielectric reaction excites the ambient gas molecules. The ambient gas flows in the gaps between several insulating dielectric tubes 200, and the plasma and air are fully mixed and reacted, thereby improving the air purification effect.
[0055] In actual implementation, the insulating medium tube 200 is a quartz glass tube.
[0056] like Figures 3-5 As shown, in some embodiments, the insulating dielectric tube 200 is filled with a fixing adhesive; the first conductive wire 310 is fixed to the wall of the corresponding insulating dielectric tube 200 by the fixing adhesive; the second conductive wire 320 is fixed to the wall of the corresponding insulating dielectric tube 200 by the fixing adhesive.
[0057] It should be noted that during transportation, if the first conductive wire 310 and the second conductive wire 320 are not well fixed inside the insulating dielectric tube 200, their positions inside the insulating dielectric tube 200 will change. This will cause the electric field strength to be too high in some areas, forming hot spots, while the electric field is insufficient in other areas, resulting in unstable discharge.
[0058] In this embodiment, the fixing adhesive can fill the entire insulating dielectric tube 200 to ensure that the first conductive wire 310 and the second conductive wire 320 are in stable position within the insulating dielectric tube 200, and to prevent uneven electric field strength caused by position changes.
[0059] like Figure 3 As shown, in some embodiments, both ends of the insulating dielectric tube 200 are open, and the ends of the insulating dielectric tube 200 are sealed with adhesive.
[0060] In this embodiment, the open design at both ends of the insulating dielectric tube 200 makes it easier to fill with the fixing adhesive, which can completely cover the internal space of the insulating dielectric tube 200, ensuring that there are no air bubbles or gaps, thereby ensuring good fixation of the conductive wire.
[0061] like Figure 4 and Figure 5 As shown, in some embodiments, the middle sections of the first conductive wire 310 and the second conductive wire 320 are both spirals that wind around the inner wall of the insulating dielectric tube 200, and both ends extend straight out from the end of the spiral.
[0062] For example, both the first conductive wire 310 and the second conductive wire 320 include: a discharge portion 330 and a connection portion 340;
[0063] The discharge section 330 is fitted onto the insulating dielectric tube 200, and the connecting section 340 is connected to the end of the discharge section 330 and passes through the insulating dielectric tube 200; the connecting sections 340 of the plurality of first conductive wires 310 are electrically connected to each other; the connecting sections 340 of the plurality of second conductive wires 320 are electrically connected to each other.
[0064] In actual implementation, the first conductive wire 310 and the second conductive wire 320 are coiled along the length of the insulating dielectric tube 200 to form a discharge section 330. An injection space 331 is formed in the middle of the discharge section 330 and between the first conductive wire 310 of the discharge section 330. A fixing adhesive is provided in the injection space 331.
[0065] In this embodiment, by filling the injection space 331 with fixing adhesive, the coiled discharge part 330 can be effectively fixed, improving its shock resistance and impact resistance during transportation or use, and ensuring that the first conductive wire 310 and the second conductive wire 320 will not shift in position, thereby maintaining the stability of the electric field.
[0066] like Figure 6 As shown, in some embodiments, several blind holes 122 are provided on opposite sides of the ventilation hole 110; a blind hole 122 is provided between two adjacent fixed through holes 121 on the same side, and the fixed through holes 121 on different sides are directly opposite the blind holes 122.
[0067] In this embodiment, multiple insulating dielectric tubes 200 are sequentially inserted into the fixing through hole 121 and the blind hole 122 in the first direction; and multiple other insulating dielectric tubes 200 are inserted into the fixing through hole 121 and the blind hole 122 in the opposite direction to the first direction.
[0068] Then, the connection part 340 of the first conductive wire 310 and the second conductive wire 320 is led to the two sides of the insulating dielectric tube 200 respectively. This can form a clear wiring path, reduce cross wiring, simplify the wiring process, and improve wiring efficiency.
[0069] like Figure 2 , Figures 6-10 As shown, in some embodiments, the mounting frame 100 has a first wiring groove 130 and a second wiring groove 140 on opposite sides.
[0070] The first wiring groove 130 is connected to the fixed through hole 121 on one side of the ventilation hole 110 and is used to accommodate the first conductive wire 310.
[0071] The second wiring groove 140 is connected to the fixed through hole 121 on the other side of the ventilation hole 110 and is used to accommodate the second conductive wire 320.
[0072] In this embodiment, the connecting portion 340 of the first conductive wire 310 is disposed in the first wiring groove 130; the connecting portion 340 of the second conductive wire 320 is disposed in the second wiring groove 140; the independent wiring grooves make the positions of the first conductive wire 310 and the second conductive wire 320 clear during wiring, which facilitates quick identification of their positions during subsequent maintenance and repair, and simplifies the troubleshooting and repair process.
[0073] like Figure 2 , Figures 6-10 As shown, in some embodiments, the mounting frame 100 has a first electrode interface 151 and a second electrode interface 152 on the other opposite sides.
[0074] The first electrode interface 151 is provided with a wire 153, which passes through the first wiring groove 130 and is connected to the first conductive wire 310.
[0075] The second electrode interface 152 is provided with a wire 153. The wire 153 of the second electrode interface 152 passes through the second wiring groove 140 and is connected to the second conductive wire 320.
[0076] The first electrode interface 151 and the second electrode interface 152 have different heights.
[0077] In this embodiment, by passing the wire 153 of the first electrode interface 151 through the first wiring groove 130 and connecting it to the connection part 340 of the first conductive wire 310, and passing the wire 153 of the second electrode interface 152 through the second wiring groove 140 and connecting it to the connection part 340 of the second conductive wire 320, this design can ensure a clear and simple wiring path and avoid the wires 153 from crossing or getting messy.
