AI Technical Summary

Technical Problem

Traditional mosquito repellent devices have a single working mode and fail to effectively adapt to various use scenarios, with electric heating diffusion modes providing poor user experience and limited effectiveness in repelling mosquitoes.

Method used

A PCB wiring heating type mosquito repellent device that integrates ultrasonic mosquito repelling and electric mosquito repellent mat functions, featuring a base with a mosquito repellent box containing a PCB heating panel, fan, heating sheets, and a rechargeable power supply module, allowing for adjustable temperature and mode settings to accommodate different spaces and scenarios.

Benefits of technology

The device effectively adapts to different application scenarios by allowing independent or joint operation of heating areas and ultrasonic emission, expanding the range of odor emission and providing a rechargeable power supply that automatically identifies and charges USB loads, enhancing user experience and repellent effectiveness.

Abstract

Provided is a PCB wiring heating type mosquito repellent device, which integrates two functions of ultrasonic mosquito repelling and mosquito repelling with an electric mosquito repellent mat. Meantime, the mosquito repellent device is provided with a plurality of heating sheets which may work independently. One side of a PCB heating panel is provided with a plurality of heating areas, and each heating area corresponds to one of the heating sheets. One side face of the heating sheet is connected with the heating area, and the other side face of the heating sheet is connected with the electric mosquito repellent mat. A heating wire is evenly laid in each heating area, and the heating wires in adjacent heating areas are connected in parallel and may supply power and heat independently.
