Description

TECHNICAL FIELD

The present invention belongs to the field of new types of tobacco products, and more particularly, relates to a smoking device capable of automatically ejecting a cigarette and performing automatic heating and a method for using the same.

BACKGROUND

The development of new types of tobacco products has entered a growth period. Numerous products have entered the tobacco market to gradually replace traditional cigarettes. Currently, heat-not-burn cigarettes provide a smoking experience similar to that of traditional cigarettes, and this smoking device uses special cigarettes for smoking. There are many such products on the market, but almost all types of such products separate the cigarette case from the smoking device. When smoking, users need to manually take a cigarette out of the cigarette case, manually put the cigarette into the smoking device to heat the cigarette for smoking, and then manually remove the cigarette butt after smoking, which requires handling the butt, several time-consuming steps, is inconvenient and interferes with an enjoyable smoking experience. In the prior art, there are cigarette cases that are capable of automatically ejecting cigarettes and smoking devices that are capable of automatically ejecting cigarette butts. However, users still need to manually put the automatically ejected cigarette into the smoking device to heat the cigarette for smoking, which is still inconvenient and interferes with an enjoyable smoking experience.
CN 107 692 317 A discloses a device capable of automatically igniting or heating a cigarette including a heat source system, a control system, and an openable and closeable top cover. The control system includes a control circuit board, a mechanical switch, a mode switching switch, an infrared light source, a light sensing switch, and a device main circuit switch. The mechanical switch controls the top cover to be opened or closed and controls the device main circuit switch to be turned on or off.
The present invention is provided to solve the above-mentioned problems.
