Description

Technical Field

[0001] The utility model relates to the technical field of Tesla coils, in particular to a Tesla coil. Background Art

[0002] The Tesla coil, also known as the Tesla coil because it's a direct transliteration of the English name "Tesla," is a distributed parameter high-frequency series resonant transformer capable of generating high-frequency voltages exceeding millions of volts. The principle of a traditional Tesla coil is to use a transformer to boost a normal voltage, which is then charged to the resonant capacitor of the primary LC circuit. When the voltage reaches the discharge threshold, the spark gap discharges, causing the primary LC circuit to resonate in series, providing sufficiently high excitation power to the secondary coil. Secondly, the frequency is equal to that of the secondary LC circuit, causing the secondary coil's inductance and distributed capacitance to resonate in series. At this point, the discharge terminal voltage is highest, resulting in the visible lightning.

[0003] Nikola Tesla, the inventor of the Tesla coil, originally used it to demonstrate wireless power transmission and the properties of high-frequency, high-voltage alternating current. Although his wireless power transmission technology failed to achieve commercialization due to the enormous investment required, the concept has been incorporated into science fiction and games. Furthermore, the solid-state Tesla coil, as a device demonstrating wireless power transmission and the properties of high-frequency, high-voltage alternating current, has demonstrated its value in science and technology demonstrations and education.

[0004] The application scenarios of Tesla coils mainly include entertainment performances, scientific research, wireless power transmission, industrial applications and medical devices.

[0005] Entertainment performances: Tesla coils are very popular in magic shows and electronic music performances because they can produce spectacular electric sparks and sound effects, adding visual and auditory shock to the performance.

[0006] Scientific Research: Tesla coils are used by scientists to study fields such as electromagnetism and electrodynamics, helping to understand the principles and applications of electromagnetic phenomena.

[0007] Wireless power transmission: The principle of Tesla coil is used to research and develop wireless power transmission technologies, such as wireless charging and wireless network transmission. Although these technologies have not yet been widely used, they represent a possible direction for future power transmission.

[0008] Industrial applications: Although Tesla coils themselves are not widely used in the industrial field, their principles and technologies are used in some special industrial applications, such as electrostatic spraying and electrostatic flocking. These applications demonstrate the potential of Tesla coil technology in specific fields.

[0009] Medical devices: Currently, some medical devices that require products to emit electromagnetic waves basically use the principle of Tesla coils. For example, radiofrequency ablation equipment for tumors,

[0010] Radiofrequency ablation machines utilize high-frequency electromagnetic wave technology, generating an alternating magnetic field through alternating current, which in turn produces high-frequency electromagnetic waves. This technology is not only widely used in the communications field but also plays an important role in the medical field, particularly in tumor ablation and pain management. In medical applications, radiofrequency ablation machines transmit high-frequency electromagnetic waves to generate heat energy, raising tissue temperature to the point of coagulative necrosis (generally believed to achieve maximum tumor tissue destruction when the temperature reaches (65±5)°C or above), thereby achieving the desired treatment. Due to its minimally invasive nature and rapid recovery, this technology is becoming the preferred treatment option for many diseases.

[0011] However, current medical Tesla coils have problems such as poor stability, poor durability, and easy wear and tear. The main reason for this is that the high-voltage end of the Tesla coil easily breaks through the air, and the enameled wire insulation grade is insufficient, which is easy to burn, causing Tesla coil component failure.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1 As shown, the present invention provides a Tesla coil, comprising a base plate 1 and a coil assembly, wherein the base plate 1 and the coil assembly are fixedly connected via a support assembly, which comprises a riser 2, a first clamping plate 3, a second clamping plate 4, a central shaft 5, and a support plate 6. The riser 2 is fixedly connected to the base plate 1, and the central shaft 5 passes through the riser 2, the first clamping plate 3, and the second clamping plate 4 in sequence and is fixedly connected to the second clamping plate 4. The support plate 6 is used to support the coil assembly. The base plate 1 is used to support the overall structure, and the riser 2 supports the coil assembly by supporting the central shaft 5. The head of the central shaft 5 is provided with a threaded hole, which is connected to the through hole provided at the head of the riser 2 by bolts.

[0031] like Figure 2As shown, in this embodiment, the coil assembly is further arranged from the inside out into an inner layer 7, an intermediate layer 8, and an outer layer 9. The space between the inner layer 7 and the intermediate layer 8 is filled with an epoxy resin layer. The inner layer 7 is configured as a quartz tube, and the intermediate layer 8 and the outer layer 9 are both configured as acrylic barrels. The inner layer 7 configured as a quartz tube can dissipate heat more quickly, preventing the Tesla secondary coil from breaking down. The epoxy resin layer filling the space between the inner layer 7 and the intermediate layer 8 has two functions: first, it can provide good high-voltage insulation for the secondary high voltage of the Tesla coil; second, it can dissipate heat generated by the Tesla coil, preventing heat accumulation, burning the enameled wire, and causing Tesla coil device failure.

[0032] In this embodiment, further, an enameled wire layer is wound around the outside of the quartz tube.

[0033] In this embodiment, further, the side shape of the support plate 6 is Y-shaped, and the support plate 6 includes an arc-shaped supporting portion 10 and a connecting portion 11. The supporting portion 10 is fixedly connected to the connecting portion 11, and the connecting portion 11 is fixedly connected to the base plate 1. The inner diameter of the supporting portion 10 is adapted to the outer diameter of the outer layer 9, so that the acrylic barrel of the support plate 6 and the outer layer 9 can be well matched and assembled, ensuring the support strength, thereby ensuring the stability of the overall structure.

[0034] like Figure 3 As shown, in this embodiment, three concentric arc grooves 12 are further opened in sequence inside the first splint 3, and the width dimensions of the three arc grooves 12 are respectively adapted to the barrel wall thickness dimensions of the inner layer 7, the middle layer 8 and the outer layer 9, thereby ensuring that the position between the first splint 3 and the inner layer 7, the middle layer 8 and the outer layer 9 is relatively fixed and does not move.

[0035] In this embodiment, further, an external thread is provided at the end of the central shaft 5 close to the second clamping plate 4 , and the second clamping plate 4 is connected to the vertical plate 2 by bolts through the external thread, thereby increasing the installation strength.

[0036] like Figure 4 As shown, in this embodiment, further, a boss 13 is opened in the middle of the central shaft 5, one end face of the boss 13 conflicts with the first clamping plate 3, and the other end face of the boss 13 conflicts with the vertical plate 2. By setting the boss 13, the first clamping plate 3 can be clamped to prevent the first clamping plate 3 from moving left and right. A threaded hole is provided at the other end of the central shaft 5, and a through hole is provided on the second clamping plate 4. The central shaft 5 and the second clamping plate 4 are connected by bolts, which improves the connection strength between the components.

[0037] The present invention provides a base plate 1 and a coil assembly, which are fixedly connected via a support assembly. The support assembly includes a vertical plate 2, a first clamping plate 3, a second clamping plate 4, a central axis 5, and a support plate 6 that cooperate with each other to improve the insulation level and the working stability and durability of the Tesla coil. The use of a quartz tube as the material for the inner layer 7 improves the heat dissipation effect of the Tesla coil secondary coil, prevents the secondary high voltage of the Tesla coil from breaking down, and reduces the risk of equipment failure. The method of encapsulating the epoxy resin layer in the inner layer 7 and the middle layer 8 is more environmentally friendly than the conventional method of applying insulating paint, protecting the health of the operator. At the same time, the insulation level and heat dissipation effect of the epoxy resin material are far higher than those of the paint material, which further improves the insulation level and heat dissipation performance of the Tesla coil secondary and improves the stability of the equipment. The structural design of the Tesla coil assembly composed of the inner layer 7, the middle layer 8, and the outer layer 9 optimizes the insulation performance of the Tesla coil and facilitates installation and testing operations.

[0038] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of this patent.
