Background technique

Traditional cigarettes need to be ignited by an open flame to produce tobacco smoke. Tobacco will release thousands of harmful compounds during the process of high temperature and cracking. The low-temperature heating smoking set can effectively reduce the production of harmful substances and make it healthier. When low-temperature smoke is used, the smoke body is inserted into the heating tube of the smoking appliance or the heating sheet is inserted into the smoke body, and then the power supply is energized to make the heating tube/heating sheet heat, and the smoke body is heated to produce smoke. After smoking a cigarette Later, the remaining part of the cigarette body is taken out by grabbing the end of the cigarette body exposed on the smoking device.
