Description

Technical Field

[0001] This invention relates to the field of electronic atomizer technology, and in particular to an atomizer and a method for preventing dry burning of atomization. Background Technology

[0002] The development of atomizer coils in electronic atomizers has gone through several stages, from the earliest fiberglass cord and resistance wire coils, to the most mature and widely used cotton wick and resistance wire coils, and now to the most advanced and stable ceramic coils. Fiberglass cords were quickly phased out due to their skin irritation, while ceramic coils, as a relatively new product, inevitably raise safety concerns. Therefore, despite issues such as dry burning, leakage, and inconsistent flavor, cotton wick coils remained a mainstream choice for a considerable period. Among the many drawbacks of cotton wick coils, dry burning is the most concerning for consumers. Besides producing a burnt taste that affects the flavor, dry burning can also cause the oxide layer on the resistance wire to flake off and be inhaled into the lungs, impacting the user's health.
