Description
Technical Field
[0001] This utility model relates to the field of circuit technology, specifically to an electronic cigarette control circuit that uses a touch chip instead of a microphone switch. 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 electronic cigarettes are typically controlled via a microphone switch. However, this method places extremely high demands on the internal airway structure and airtightness of the electronic cigarette, resulting in a complex internal structure design. This complex structure can lead to the risk of e-liquid leakage damaging the main control circuit board, thus compromising safety. Furthermore, the soldering process between the microphone switch and the main control circuit board is quite complicated and is usually done manually, which is not only costly in terms of labor but also inefficient in terms of production.
