Electric fly swatters typically consist of a handle and a swatter head. The handle is usually made of engineering plastic, with common specifications such as a 200mm width, 43cm length, and a weight of approximately 225g.
Electric fly swatters are primarily powered by rechargeable lead-acid or lithium batteries, although some models use AA batteries. Common built-in battery capacities include 400mAh, 650mAh, 800mAh, and 1200mAh, with some products supporting USB charging.
Its core electrical and structural components include a high-voltage oscillation circuit board, an oscillating tube (such as an 8050 transistor), a step-up transformer, voltage multiplier capacitors and diodes, and a high-voltage metal grid. The high-voltage grid typically has a three-layer structure: an outer safety mesh and a middle working mesh.
Modern electric mosquito swatters often integrate multiple additional functions, such as LED lighting, ultraviolet mosquito-attracting lamps, telescopic or rotating swatter designs, dual safety switches (child locks), intelligent flash charging, and air quality and temperature monitoring functions.
According to the industry standard QB/T 4496-2013 "Electric Mosquito Swatters", under normal working conditions, the working voltage of the high-voltage mesh of an electric mosquito swatter should be within the range of 2000V~4200V. The measured working voltage of commercially available products is commonly between 2430V and 2980V.
