This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,114.

Summary of the Inventive Concept

An improved hand-held electric barbecue device featuring advanced temperature control, enhanced safety, quick-release mechanism, ergonomic design, and built-in food thermometer, ensuring consistent cooking results, improved user experience, and increased safety.

Background and Problem Solved

The original hand-held electric barbecue device, while providing a convenient way of cooking outdoors, had limitations in terms of temperature control, safety, and usability. The new inventive concept addresses these limitations by introducing advanced features that make the device more efficient, safer, and user-friendly.

Detailed Description of the Inventive Concept

The enhanced hand-held electric barbecue device comprises a driving system with a temperature control module to regulate heat output, ensuring consistent cooking temperatures. A thermal overload protection mechanism automatically shuts off the motor when an overheating condition is detected, enhancing safety. The linkage mechanism is replaced with a modular quick-release system, allowing for rapid detachment and reattachment of the barbecue fork. The handle is ergonomically redesigned to reduce fatigue and improve grip comfort, featuring a contoured grip surface and a strategically positioned thumb rest. The barbecue fork is modified to include a built-in food thermometer, providing real-time temperature readings and ensuring perfectly cooked food.

Novelty and Inventive Step

The new inventive concept introduces several novel features, including the temperature control module, thermal overload protection mechanism, modular quick-release system, ergonomic handle design, and built-in food thermometer, which collectively provide a significant improvement over the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the type of temperature control module, using different materials for the ergonomic handle, or integrating additional sensors for monitoring cooking conditions. Variations of the quick-release system could include different locking mechanisms or adjustable tension settings.

Potential Commercial Applications and Market

The enhanced hand-held electric barbecue device has significant commercial potential in the outdoor recreation and camping industries, offering a more efficient, safer, and user-friendly solution for outdoor cooking. The device could be marketed through online retailers, outdoor gear stores, and camping supply companies.
