Description

Technical Field

[0001] This utility model relates to the field of circuit technology, specifically to an electronic cigarette control circuit with uninterrupted power supply from dual batteries. Background Technology

[0002] Electronic cigarettes are electronic products that mimic traditional cigarettes, possessing the same appearance, smoke, taste, and feel, and even offering a wider variety of flavors than regular cigarettes. They work by atomizing nicotine and other substances into vapor for users to inhale. Generally, electronic cigarettes consist of three main parts: a cartridge containing the nicotine solution, an vaporizer, and a battery. The atomizer, powered by the battery, transforms the liquid nicotine in the cartridge into vapor, giving the user a similar sensation to smoking, allowing them to "exhale clouds of smoke."

[0003] Currently, most e-cigarettes on the market consist of a cartridge and the main body. The cartridge typically comprises a non-removable e-liquid tank and an atomizer. The e-liquid in the tank is atomized by the atomizer for the user to inhale. There are currently two main atomization methods: one is heat atomization, which uses a heating coil and a heating mesh to heat and atomize the e-liquid in the tank for inhalation; the other is ultrasonic atomization, where the e-liquid is ultrasonically atomized by the cartridge. Regardless of the atomization method, the atomizer in the cartridge needs to be powered, and the main body of the e-cigarette must contain a main control circuit board and a power supply.

[0004] In existing technologies, traditional e-cigarettes are typically powered by a power source within the e-cigarette body. During daily use, once the power source in the e-cigarette body runs out of power, it needs to be recharged, at which point the e-cigarette cannot be used. However, the charging time for e-cigarettes is often quite long, at least several hours. If the user needs to use the e-cigarette during this time, it cannot be used, which does not provide a good user experience. Utility Model Content
