AI Technical Summary
In existing electronic cigarettes, the first switching unit is prone to damage due to excessive temperature rise during prolonged operation, which can lead to an increase in the internal temperature of the entire electronic cigarette and potentially cause safety issues. Furthermore, existing protection mechanisms are prone to failure or are incomplete, and cannot effectively prevent the first switching unit from operating for extended periods.
A battery protection circuit is adopted, including a battery protection module and a second switching unit. Two-stage over-suction protection is achieved through a branch detection unit and a logic control unit. The logic control unit keeps the second switching unit open after detecting that the conduction time of the heated branch exceeds a preset time to prevent continuous current flow.
It effectively prevents the first switching unit and system control module from being damaged by high temperature, reduces the risk of electronic cigarette damage, improves safety, and does not require the addition of an extra switching unit, is low in cost, compatible with existing electronic cigarettes, and has a wide range of applications.
