Description

Technical Field

[0001] This utility model relates to the field of ozone generator technology, specifically an overvoltage protected ozone generator. Background Technology

[0002] Ozone, as a strong oxidant, has wide applications in drinking water treatment, air purification, food disinfection, medical sterilization, and industrial waste gas treatment. Ozone generators, as the core equipment for ozone production, typically operate based on technologies such as dielectric barrier discharge, corona discharge, or electrolysis. They convert oxygen molecules in the air or oxygen source into ozone through a high-voltage electric field. However, existing ozone generators generally suffer from overvoltage risks during operation, leading to reduced equipment reliability, shortened lifespan, and even safety accidents.

[0003] Current ozone generators rely on high-voltage power supplies to drive the discharge module. However, in actual operation, the high-voltage power supply is susceptible to grid fluctuations, sudden load changes, and environmental factors (such as temperature and humidity), causing the output voltage to rise instantaneously, exceeding the dielectric layer's tolerance threshold and leading to breakdown, short circuit, or permanent equipment damage. Existing overvoltage protection schemes have slow response speeds and cannot adapt to rapid changes in transient overvoltages, resulting in insufficient reliability and safety. Therefore, a new technical solution is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide an overpressure protected ozone generator, which solves the problems of slow response speed, inability to adapt to rapid changes in transient overpressure, and insufficient reliability and safety of existing overpressure protection schemes proposed in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an overvoltage protected ozone generator, comprising a generator body, a first slide rail fixedly connected to the bottom surface of the base at the bottom of the generator body, a first slider slidably connected to the surface of the first slide rail, conductive rods and crossbars fixedly connected to the left and right sides of the first slider, an iron block fixedly connected to the far end of the crossbar, and a metal rod with a power supply wire wound around the horizontal side of the iron block.

[0006] In this technical solution, a metal rod with a power supply wire wound around it is set on the inside of the base. When the voltage is too high and the current surges, the magnetism at both ends of the metal rod increases, attracting the iron block to detach the conductive plug from the conductive tube, thereby disconnecting the circuit and preventing the equipment from being damaged by excessive voltage, thus improving safety and practicality.

[0007] Preferably, the metal rod is fixedly connected to the side wall surface of the fixing plate, the fixing plate is fixedly connected to the inner bottom surface of the base, one end of the power supply line is connected to the power module, and the other end of the power supply line is connected to the conductive plug on the inner side of the support block.

[0008] Preferably, a limiting block is fixedly connected to one end of the first slide rail near the metal rod, and a spring is fixedly connected between the limiting block and the first slider.

[0009] Preferably, a protrusion is fixedly connected to the inner side wall of the base corresponding to the horizontal height of the conductive rod, and a conductive tube is fixedly connected to the side wall of the protrusion, with one end of the conductive rod inserted into the inner side of the conductive tube.

[0010] Preferably, a second slide rail is fixedly connected to the bottom surface of the base below the conductive plug rod. The second slide rail is parallel to the first slide rail. A second slider is slidably connected to the surface of the second slide rail. A ceramic plate is fixedly connected to the top of the second slider.

[0011] Preferably, the side walls of the first slider and the second slider are rotatably connected by a hinge rod via a hinge seat, and the hinge rod remains parallel to the inner bottom surface of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a base at the bottom of the generator body, and a metal rod with a power supply wire wound on the inside of the base. When the voltage increases abnormally and the current surges, the magnetism at both ends of the metal rod increases, attracting the iron block to disengage the conductive plug from the conductive tube, thereby disconnecting the circuit and preventing the equipment from being damaged by excessive voltage. Compared with traditional monitoring and protection equipment, this device significantly shortens the response time and improves safety and practicality.

[0014] 2. When the metal rod attracts the iron block, the first slider pulls the second slider along the second slide rail through the hinge rod, so that the ceramic plate reaches between the conductive rod and the conductive tube, forming a physical isolation, avoiding the danger caused by possible electric arc, eliminating the risk of sparks, and further improving the safety and practicality of the device.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0021] An overvoltage-protected ozone generator, see [link / reference] Figures 1 to 3 The generator includes a generator body 1. A first slide rail 7 is fixedly connected to the bottom surface of the base 2 at the bottom of the generator body 1. A first slider 8 is slidably connected to the surface of the first slide rail 7. Conductive plugs 12 and crossbars 11 are fixedly connected to the left and right sides of the first slider 8, respectively. A protrusion 13 is fixedly connected to the inner side wall of the base 2 at the horizontal height of the conductive plug 12. A conductive tube 14 is fixedly connected to the side wall of the protrusion 13. One end of the conductive plug 12 is inserted into the inner side of the conductive tube 14. The first slider 8 slides on the surface of the first slide rail 7, and the conductive plug 12 will be inserted into the inside of the conductive tube 14, thereby ensuring the continuity of the circuit. The surface of the conductive tube 14 can be provided with an insulating skin. One end of the conductive tube 14 is located inside the protrusion 13 and is connected to a wire. The wire continues upward to supply power to the equipment inside the generator body 1 above, ensuring the normal operation of the generator body 1.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, an iron block 111 is fixedly connected to the far end of the crossbar 11. A metal rod 5 with a power supply wire 6 wound around it is provided on the horizontal side of the iron block 111. The metal rod 5 is fixedly connected to the side wall surface of the fixing plate 4. The fixing plate 4 is fixedly connected to the inner bottom surface of the base 2. One end of the power supply wire 6 is connected to the power module 3, and the other end of the power supply wire 6 is connected to the conductive plug 12 inside the support block 10. According to Ampere's law, when energized, the two ends of the metal rod 5 wound around the power supply wire 6 will generate opposite magnetic poles, which will attract the iron block 111. At this time, the voltage and current are normal, and the generated magnetism is not enough to attract the iron block 111 to the metal rod 5. Therefore, the conductive plug 12 is still inserted in the conductive plug tube 14, and the circuit is in the connected state. However, once a certain load is exceeded, the voltage and current increase, which leads to the strengthening of the magnetism of the metal rod 5, which completely attracts the iron block 111. The conductive plug 12 will then detach from the conductive plug tube 14, causing the circuit to break. This temporarily disconnects the circuit, avoids damage to the equipment due to excessive voltage, and improves safety and practicality.

[0023] It should be noted that although the power module 3 is located in the base 2, it is isolated from other devices by a protective plate. The protective plate is made of high magnetic permeability materials, such as permalloy and silicon steel, to prevent the magnetic field from affecting the power supply. At the same time, a protective plate is also provided between the base 2 and the generator body 1 above it to prevent any impact.

[0024] It is worth noting that, such as Figure 3 As shown, a limiting block 701 is fixedly connected to one end of the first slide rail 7 near the metal rod 5. A spring 9 is fixedly connected between the limiting block 701 and the first slider 8. The spring 9 is in a compressed state, thereby pushing the first slider 8 to move away from the metal rod 5. When the iron block 111 is attracted, the spring 9 will play a certain blocking role to prevent the conductive rod 12 from directly disengaging from the conductive tube 14. The spring 9 also plays a resetting role. After the circuit is disconnected, the magnetism gradually disappears, and the first slider 8 will be pushed by the spring 9 to allow the conductive rod 12 to be reinserted into the conductive tube 14.

[0025] Furthermore, such as Figure 2 and Figure 3 As shown, a second slide rail 15 is fixedly connected to the bottom surface of the base 2 below the conductive plug 12. The second slide rail 15 is parallel to the first slide rail 7. A second slider 16 is slidably connected to the surface of the second slide rail 15. A ceramic plate 17 is fixedly connected to the top of the second slider 16. The second slider 16 moves along the second slide rail 15. The ceramic plate 17 on its surface is insulating and can enter between the conductive plug 12 and the conductive tube 14 to form physical isolation, further improving safety during power outages.

[0026] It is worth noting that, such as Figure 2 As shown, a hinge rod 18 is rotatably connected between the side walls of slider 8 and slider 16 via a hinge seat. The hinge rod 18 remains parallel to the inner bottom surface of the base 2. When the metal rod 5 attracts the iron block 111, slider 8 pulls slider 16 along slide rail 15 via hinge rod 18, thereby allowing the ceramic plate 17 to reach between the conductive rod 12 and the conductive tube 14, forming a physical isolation to avoid the danger caused by possible electric arcs, and further improving the safety and practicality of the device.

[0027] It should be noted that the operating principle of an ozone generator is to ionize the input air or oxygen through a high-voltage power supply. Oxygen molecules absorb energy and break down into oxygen atoms under the influence of an electric field. These oxygen atoms then combine with unbroken oxygen molecules to generate ozone molecules. The core mechanisms include dielectric barrier discharge (DBD), corona discharge, or electrolysis. For example, in DBD, an insulating medium (such as ceramic or glass) is filled between the high-voltage electrode and the grounding electrode. When a high-frequency high voltage of several kilovolts to tens of thousands of volts is applied, the gas in the electrode gap is broken down, forming a micro-discharge channel. The electric field energy causes oxygen molecules to undergo collisional ionization and recombination reactions, generating ozone and heat simultaneously. The dielectric layer limits the discharge current to prevent arc formation and assists in heat dissipation to maintain reaction stability. The final output ozone gas concentration is determined by the discharge power, gas flow rate, dielectric material, and environmental parameters. Ozone generators are currently a relatively mature existing technology and are not the technical solution to be protected in this utility model. They are readily available on the market; therefore, the specific internal components and devices will not be described in detail.

[0028] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

[0029] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
