Abstract: A tobacco heater with straight through heating tube, comprising a housing with a replaceable battery and a control PCB board; the housing has a mouthpiece; each side of the housing is hinged with an openable seagull door; inside the door is a heating tube at the middle housing; between the mouthpiece and the tube is an airflow path; inside each door is a compress tool for blocking the tobacco; the tube is electrically connected to the board. An openable seagull door is hinged on both sides of the housing to block the tube formed on the inner side of the door in the housing middle to form a straight through tobacco heating container. Tobaccos can be quickly and easily loaded by opening the doors, and the heater can be powered on when closed doors; opening doors, the tobacco heating residues can be easily and quickly cleaned after using.

Abstract: The invention discloses a granular cigarette, comprising a tobacco tube encapsulated with tobacco particles; one end of the tube is provided with a filtering component and the other end a sealing component; the tobacco particles are arranged between the filtering and the sealing components. The filtering component can adopt traditional filtering cotton or filtering silica gel strip; the sealing component can adopt aluminum foil, tobacco sheet, self-closing silica gel plug, and glue film. A capsule packaging can be further adopted for the tobacco particles to solve the problem that the particles easily fall out during production. The invention replaces the low-temperature non-burning cigarette with a thin-film technology by encapsulating a granular cigarette, which has the advantages of simple production process, sufficient heating, uniform smoke, and the smoke can shuttle between particles; the problem of easy falling out of particles can be solved by the filtering and the sealing components.

Abstract: The invention discloses a tobacco cartridge and a cigarette air heating device thereof; the cartridge comprises a tobacco container that has openings at both ends where a mental foil is encapsulated; the tobacco can be sealed with the metal foil to prevent moisture; the metal foil has low strength and is convenient for puncturing, with the advantages of resistant storage, convenient transportation, and quick use; the central portion of the cigarette air heating device has an air guiding device that comprises a base and an air guiding tube; when in use, the tube is inserted into the cartridge and sequentially pierces through two layers of metal foil; the cartridge conducts heat flow to the cartridge, so that the heating is more uniform, and the hot air flow can be buffered, which enables that the air temperature in the later period is longer and the taste is more pure.
