Description

Technical Field

[0001] This utility model relates to the field of scientific and educational tools, specifically a glow discharge observation device. Background Technology

[0002] Glow discharge is a self-sustaining discharge phenomenon that occurs in low-pressure gases. When the electric field strength exceeds a certain threshold, gas atoms or molecules are excited and ionized, resulting in a stable and continuous luminescence. Glow discharge typically occurs in a closed container filled with gas and equipped with electrodes, which conduct electricity through an electric field. Glow discharge is accompanied by a faint but continuous glow, the color of which varies depending on the type of working gas.

[0003] However, existing glow discharge experimental devices are usually complex in structure and inconvenient to operate, and have the following problems: 1. Inconvenient connection method: Traditional glow discharge experiments require manual connection of electrodes, which not only affects experimental efficiency but also easily leads to poor contact; 2. Complex circuit and insufficient safety: The exposed connection of high-voltage power supply may pose a risk of electric shock, and improper use may cause damage; 3. Limited visualization effect: Some devices can only light up a single gas tube, lacking diverse display methods, which is not conducive to teaching interaction. Utility Model Content
