Description

cigarette heater

technical field

The utility model relates to a heating device, in particular to a cigarette heater, which is used for heating non-burning tobacco products of cigarettes.

Background technique

Tobacco products are a special consumer product. In recent years, the impact of traditional smoking on health and the environment has gradually attracted the attention of countries all over the world. Tobacco manufacturers are committed to providing consumers with less harmful tobacco products. For this reason, a tobacco product that can be smoked by heating without lighting the tobacco has been developed. Because the heating temperature is much lower than the combustion temperature, it can effectively reduce the harmful components produced by high-temperature combustion and cracking of tobacco, and greatly reduce the release of chemical components in mainstream smoke. As a new form of tobacco consumption, heat-not-burn tobacco products are gradually welcomed by some tobacco consumers, and are increasingly accepted by cigarette consumers in most countries. However, the existing heat-not-burn tobacco heaters generally use external heating sources for overall heating or internal heating through specially processed hollow tobacco columns, which have complex structures and high production costs; secondly, there are also inventions that use piercing heating , but it needs to use some motors or spring mechanisms to perform the piercing action, the mechanism is complicated, the cost and technical difficulty are high; third, some existing heating devices usually have reusable metal or plastic mouthpieces, which are different from conventional cigarette consumption. Varying experience and low consumer acceptance, while reusable mouthpieces require cleaning and carry bacteria and odor residue.

Contents of the invention

The utility model provides a cigarette heater, which comprises a cylindrical shell and a heating device with a sharp thorn head. Its structure is that the bottom of the heating device is fixed on the middle part of the bottom end face of the cylindrical shell, so that the pointed end is positioned at the inner axis of the cylindrical shell, and the heating device and the cylinder There are gaps between the inner walls of the housing. The inner diameter of the inlet at the top of the cylindrical shell is slightly larger than the outer diameter of the filter cigarette to be inserted. When the cut tobacco end of the filter cigarette is inserted, the spikes on the head of the heating device axially penetrate the filter cigarette from the center of the cut tobacco end Inside the shredded tobacco section, the filter tip section of the filter cigarette remains outside the cylindrical shell for the smoker to inhale the smoke generated by heating by the heating device.

The heating device can be made of a thin-walled stainless steel tube with a diameter of 2.5mm, and a resistance heating wire is installed inside, powered by a battery or USB, and one end of the stainless steel tube is processed into a sharp needle-shaped bevel.
