Technical Field
[0001] An electrode tube for a plasma generator, belonging to the field of isothermal plasma technology. Background Technology
[0002] Plasma is an ionized gas that is electrically neutral overall, composed of electrons, positive and negative ions, free radicals, and ground-state or excited-state molecules. It possesses advantages such as high energy and abundant active components. Plasma is generally obtained through a plasma generator. The main working principle of a plasma generator is to connect positive and negative high voltages to the positive and negative electrodes, respectively. These high voltages ionize the air, generating a large number of positive and negative ions. The instantaneous neutralization of positive and negative charges by these ions in the air produces a huge release of energy, leading to changes in the structure or energy conversion of surrounding bacteria, thereby causing bacterial death and achieving its bactericidal effect.
[0003] A plasma generator typically includes a positive electrode tube and a negative electrode tube (collectively referred to as electrode tubes). Both the positive and negative electrode tubes consist of a tube body and electrodes housed within it. The positive high voltage is connected to the positive electrode in the positive electrode tube, and the negative high voltage is connected to the negative electrode in the negative electrode tube. Because the plasma generator operates at a relatively high voltage, the distance between the positive and negative electrode tubes, especially the distance between their terminals, should be maximized to ensure good insulation.
[0004] However, the frame size of the fixed electrode tube in a plasma generator is fixed. Therefore, in the prior art, the commonly used method is to design the two ends of one electrode tube (usually the positive electrode) as a sloping structure, that is, to design the two ends of the tube body as a sloping upward structure, and then bend it again to form a horizontal shape parallel to the tube body. This is exemplified by the electrode tube structure described in Chinese Utility Model Patent Application No. 202322599299.4, filed on September 25, 2023, entitled "A Plasma Generator and its Electrode Fixed Insulating Bridge". This design increases the distance between the terminals of the positive and negative electrodes and facilitates the addition of an insulating structure at one end of the sloping structure.
[0005] The above solution has the following problems when implemented: Since the frame size of the fixed electrode tube in the plasma generator is fixed, and the electrode tube body is generally made of glass or ceramic material with good insulation properties, it is difficult to control the accuracy and length at the inclined ends of the electrode tube with the slope structure at both ends during processing, which results in a low yield and increases the cost of the equipment to a certain extent. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an electrode tube for a plasma generator in which only one end of the terminal is bent to form an interlaced structure with the tube body, and the other end is designed as a straight structure. This greatly reduces the processing difficulty of the electrode tube, makes it easier to control the accuracy and overall length of the electrode tube during processing, and improves the yield rate.
[0007] The technical solution adopted by this utility model to solve its technical problem is: the electrode tube of the plasma generator includes a tube body, one end of which is a terminal, and an electrode is provided in the tube body. The electrode is led out from the terminal. The characteristic is that: a bend is provided on one side of the terminal, so that the terminal and the tube body are arranged alternately, and the other end of the tube body relative to the terminal is a straight end with a straight structure.
[0008] Preferably, insulation structures are provided at both the wiring ends and the straight ends of the pipe body.
[0009] Preferably, the insulation structure provided at the terminal of the tube body includes an outer insulation tube, which is an integral structure with the tube body.
[0010] Preferably, the insulation structure provided at the terminal of the tube body further includes an inner insulating tube located inside the tube body, with the electrode located at the center of the inner insulating tube.
[0011] Preferably, the insulating structure set at the straight end of the pipe body is an insulating column that seals the pipe opening.
[0012] Preferably, the insulating column is a solid structure.
[0013] Preferably, the insulating column and the tube body are an integral structure.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] In the electrode tube of this plasma generator, only one end of the wiring terminal is bent to form an interlaced structure with the tube body, while the other end is designed as a straight structure. This greatly reduces the processing difficulty of the electrode tube, makes it easier to control its accuracy and overall length during processing, and improves the yield rate.
[0016] In this plasma generator, the terminal of the electrode tube is designed with a bend so that the terminal is higher than the tube body. After the electrode tube is installed in the main frame of the plasma generator, the terminal is higher than the bottom of the main frame, thus increasing the distance between the tube body and the corresponding other electrode and improving the insulation.
[0017] At the electrode tube terminals of this plasma generator, the outer insulating tube is fused to the tube body, increasing the thickness of the insulating material and further improving the insulation performance.
[0018] In the straight line of the electrode tube of this plasma generator, a solid insulating column is set and fused to the tube body. This improves the insulation of the non-connection terminals and also solves the problem that the solid insulating column can effectively block the flow of water after the electrode is rinsed, thus improving the safety of use.

[0025] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.
[0026] like Figures 1-3 As shown, an electrode tube (hereinafter referred to as electrode tube) of a plasma generator includes a tube body 2, which has a hollow structure, and an electrode 6 is disposed inside the tube body 2 (see...). Figure 4 One end of the tube body 2 is a terminal, and the inner end of the electrode 6 extends horizontally into the interior of the tube body 2, while its outer end is led out from the opening of the tube body 2 for connection to an external high-voltage power supply. In practical use, it is preferable to connect this electrode tube to the positive terminal of an external power supply. The tube body 2 is preferably made of inorganic materials such as glass.
[0027] The tube body 2 includes a tube body with a terminal at one end. The tube body and the terminal are connected by a bend 3. The bend 3 is inclined upwards and then bent horizontally again, making the end of the terminal parallel to the tube body 2. By setting the bend 3, the terminal of the tube body 2 is higher than the tube body. Therefore, after the electrode tube is installed in the main frame of the plasma generator, the terminal is higher than the bottom of the main frame, thus increasing the distance between the electrode tube and the corresponding other electrode and improving insulation.
[0028] Combination Figure 4 An outer insulating tube 4 is fitted around the wiring terminals of the tube body 2. The outer insulating tube 4 is preferably made of the same material as the tube body 2, and the outer insulating tube 4 is fused to the insulating column 1 and the tube body 2 by heat fusion. An inner insulating tube 5 is provided inside the tube body 2, and the electrode 6 is located at the center of the inner insulating tube 5.
[0029] The other end of the pipe body 2 relative to the terminal is a straight structure, and an insulating post 1 is provided at the pipe opening at the straight end of the pipe body 2, combined with... Figure 5 The insulating post 1 is a solid structure made of organic material, preferably the same material as the tube body 2. The end of the insulating post 1 is inserted into the interior of the tube body 2, and the insulating post 1 and the tube body 2 are fused together by heat fusion.
[0030] As described above, in this electrode tube, only the end containing the wiring terminal is designed with a bend 3. At the wiring terminal, the bend 3 makes the wiring terminal higher than the tube body. After the electrode tube is installed in the main frame of the plasma generator, the wiring terminal is higher than the bottom of the main frame, thus increasing the distance between the electrode tube and the corresponding other electrode, improving insulation, and significantly reducing the processing difficulty of the electrode tube. This makes it easier to control the precision and overall length of the electrode tube during processing, improving the yield rate. Simultaneously, the outer insulating tube 4 is fused to the tube body 2 at the wiring terminal, increasing the thickness of the insulating material and further improving insulation.
[0031] At the other end of the tube body 2, which is opposite to the terminal, a solid insulating post 1 is provided and fused to the tube body 2. This improves the insulation of the non-terminal and also solves the problem that the solid insulating post 1 can effectively block the flow of water after the electrode is rinsed, thus improving the safety of use.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
