Multi-fuel-canister insect repellent system
The invention provides a hydrocarbon-fueled device for heating and dispensing a volatile substance, such as an insect repellent. The device provides a long-lasting 48-hour fuel system, multiple fuel canisters that can be exchanged without interrupting the operation of the device, an illuminated indicator that provides a visible indication of the operating state of the device from any viewing angle, and a flame-extinguishing safety lid. During the warm-up phase, the indicator indicates this state by pulsing. Once the device reaches operating temperature, the indicator emits a steady light, indicating proper operation. In the event that the device cools below the operating temperature, the light will pulse, alerting the user to check the flame and/or fuel supply. The user can initiate complete, properly-controlled operation of all functions of the device via the operation of a single on-off switch.
