Description

Technical Field

[0001] This utility model relates to the field of plasma generating equipment technology, specifically a plasma generating device. Background Technology

[0002] A plasma generator is a special type of high-voltage positive and negative ion generator. It generates high-energy, high-concentration positive and negative ions by continuously ionizing the air with needle-shaped positive electrodes (4500-4700 volts). When positive and negative ions exist simultaneously, they neutralize each other, effectively killing various bacteria in the air. Existing air plasma purification devices generally consist of multiple components, such as an air intake device, a disinfection and sterilization device, and an air exhaust device. The disinfection and sterilization plasma device includes a plasma generating cylinder and a discharge module within it. The discharge needles (thin and fixed at the top) in the discharge module discharge plasma within the generating cylinder, and a bottom fan then blows air through each generating cylinder for disinfection and sterilization. In existing technologies, the generating cylinders used in plasma generation mechanisms are mostly cylindrical. The gaps between cylinders prevent the maximization of space utilization, disinfection efficiency, and airflow. Furthermore, plasma generating components are generally difficult to disassemble and install, making equipment maintenance cumbersome and complex, causing inconvenience to staff. Therefore, we propose a plasma generating device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides a technical solution: a plasma generating device, including a mounting housing 1, wherein a plurality of plasma generating cylinders 11 are arranged in a rectangular array in the inner cavity of the mounting housing 1, and a discharge needle 12 is installed at the geometric center of the plasma generating cylinder 11. The mounting housing 1 is embedded in the mounting frame 16 and locked and fixed by the connecting component 15.

[0020] The connecting component 15 includes a screw head 151 and a handle 153 respectively disposed at its two ends. The sides of the mounting housing 1 and the mounting frame 16 are respectively provided with connecting holes 14. The screw head 151 passes through the corresponding connecting hole 14 to achieve fixation. The side of the mounting frame 16 is connected to the positioning plate 19 through a pull rod 18. The side of the positioning plate 19 is equipped with a PCB board 2.

[0021] In the above scheme, a resin plate 13 is provided on the side of the mounting housing 1. The resin plate is a type of artificial stone slab, which has good advantages such as flame retardancy, sound insulation, impact resistance, deformation resistance, and corrosion resistance, and also has high surface hardness and long service life.

[0022] In the above scheme, the cross-section of the plasma generating cylinder 11 is square or regular hexagonal. By integrating several plasma generating cylinders 11 inside the mounting housing 1, and correspondingly installing discharge needles 12 inside the plasma generating cylinders 11, the device achieves high integration, good air circulation, and maximized sterilization efficiency. When airborne particles pass through the ion generating device, oxygen and water molecules collide with electrons of a certain energy, forming positive and negative oxygen ion clusters, respectively. These positive and negative ion clusters have strong mobility and instability, reacting with gaseous pollutant molecules in a very short time. After a series of reactions, they ultimately generate small molecule compounds such as water and carbon dioxide, which are harmless to the human body or have greatly reduced harmfulness. At the same time, the oxygen ion clusters can effectively kill bacteria in the air and reduce the number of bacteria indoors.

[0023] In the above scheme, a positioning block 152 is movably sleeved on the screw head 151, and the positioning block 152 is snapped into the placement groove 17 on the outside of the mounting frame 16. The mounting housing 1 is embedded into the mounting frame 16 through the connecting assembly 15, achieving rapid installation of the mounting housing 1. Furthermore, the connecting assembly 15, composed of the screw head 151 and the handle 153, facilitates rapid installation and disassembly of the mounting housing 1, making equipment maintenance easier, effectively reducing the operating cost of the plasma generator, and solving the problem of difficult rapid disassembly and assembly of the disinfection module in ordinary plasma generators, thus bringing convenience to users.

[0024] In the above scheme, the PCB board 2 is electrically connected to the discharge needle 12 via wire 21, and the number of PCB boards 2 corresponds one-to-one with the number of discharge needles 12. Specifically, the PCB board 2 and the discharge needle 12 are electrically connected to the power supply.

[0025] In the above scheme, a heat dissipation channel is provided between adjacent PCB boards 2, and heat dissipation holes are provided on the positioning plate 19. Furthermore, a fan or air duct is installed on the side of the positioning plate 19 to introduce airflow into the plasma generating cylinder 11.

[0027] Working principle:

[0028] This plasma generator integrates several plasma generating cylinders 11 inside the mounting housing 1, and correspondingly installs discharge needles 12 inside the plasma generating cylinders 11. This results in high integration and good air circulation, allowing ions to diffuse more quickly into the room and maximizing sterilization efficiency. The mounting housing 1 is embedded into the mounting frame 16 via the connecting component 15, enabling rapid installation of the mounting housing 1. Furthermore, the connecting component 15, consisting of the screw head 151 and the handle 153, facilitates quick installation and disassembly of the mounting housing 1, making maintenance easier and effectively reducing the operating cost of the plasma generator. It also solves the problem of difficult quick disassembly and assembly of the disinfection module in ordinary plasma generators, bringing convenience to users.
