Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of low-temperature non-burning tobacco, and relates to a granular low-temperature non-burning smoking device used in conjunction with a cigarette cartridge. Background Art
[0002] In recent years, the new tobacco field has been developing and innovating rapidly, with electronic cigarettes and low-temperature non-burning tobacco products as the mainstream direction. Electronic cigarettes, also known as steam cigarettes, work on the principle of heating nicotine solution to achieve atomization. Because the heated object is a liquid, the heating element requirements are not high. Low-temperature non-burning tobacco products, also known as heat-not-burn tobacco, work on the principle of heating tobacco regeneration to achieve smoke generation. The heating element contacts the tobacco regeneration to transfer heat, and the heating temperature only needs to be 300-380°C, which is much lower than the 700°C temperature of traditional cigarettes when heated by open flames. When using low-temperature non-burning tobacco products, the taste is more like traditional cigarettes, and therefore, they are more popular with consumers.
[0003] Tobacco regeneration and heating elements are necessary for smoking low-temperature non-burning tobacco products. At present, tobacco regeneration is mainly in the form of flakes and particles. Among them, the particle type has broad application prospects due to its simple processing method and good smoking effect. However, practice shows that there are many factors that affect its final effect, such as: the manufacturing method of tobacco particles, the heating temperature of the heating element, the airtightness of the smoking device, etc.
[0004] The shell filled with regenerated tobacco is called a "smoke cartridge". When in use, the smoke cartridge is heated by the heating element built into the smoking device to produce smoke, which is at a high temperature and needs to be cooled and filtered.
[0005] Most of the existing low-temperature non-burning products are used after low-temperature non-burning cigarettes are loaded into smoking utensils. The low-temperature non-burning cigarettes are equipped with cigarette cartridges and cooling filter components. The smoking utensils include heating elements and batteries, among which the batteries are fixed at the bottom of the smoking utensils. The cooling filter components of existing low-temperature non-burning cigarettes are discarded together with the cigarette cartridge residues after use. Therefore, low-temperature non-burning cigarettes are all disposable trial products, which leads to a series of problems such as increased manufacturing costs of low-temperature non-burning cigarettes, complex manufacturing processes, and environmental pollution.
[0006] Therefore, providing a low-temperature non-burning tobacco device that can not only ensure the use effect and convenience, but also reduce the manufacturing cost and process and is beneficial to environmental protection has become the current research and development direction and focus in the field of low-temperature non-burning tobacco.

[0012] The present invention, through the above unique filtering structure, that is, by using a unique smoke treatment part with stable and excellent filtering performance, greatly improves the filtering effect of smoke when the smoking device is used. In addition, the filter part is easy to disassemble and assemble, and the operation is simple. The filter part can be recycled and reused, thereby achieving a series of significant effects such as saving resources and protecting the environment.

[0014] The present invention realizes a suction method in which air flows smoothly into the bottom end of the smoking device and smoke flows out from the top end thereof through the above structure of the cigarette cartridge cavity, which is conducive to complying with the smoking habits of traditional cigarettes and is more easily accepted by consumers. In addition, the above structure of the cigarette cartridge cavity can also ensure convenient disassembly and assembly of the cigarette cartridge, especially the setting of the sealing ring on the inner side of the cigarette cartridge cavity cover, which can ensure the reliability and airtightness of the connection between the corresponding components in the smoking device, and can reliably and firmly keep the cigarette cartridge fixed in the cigarette cartridge cavity.
[0015] Preferably, the electric control unit includes a battery and a start switch, a liquid crystal screen, a circuit board, a vibration component, a Bluetooth, a Bluetooth chip, a memory card, a display light and other electronic functional components.
