Description

Heating cavity structure for improving smoking stability of heating cigarettes Technical Field The utility model belongs to the field of novel tobaccos, and particularly relates to a heating cavity structure for improving the smoking stability of a heating cigarette. Background In recent years, various new tobacco products have come into the field of view, and one of them is the heating of cigarette products. The heated cigarettes can effectively reduce the content of harmful substances in smoke due to the characteristic of non-combustion during heating, and are widely concerned at home and abroad. However, because the development time is short, the technology is not perfect, and there are many defects, one of which is that the stability of the smoke from mouth to mouth during suction is poor, and the smoke with different mouth numbers has larger sensory difference, and the smoke with the front mouth and the back mouth is lighter. The Henan tobacco industry Limited liability company discloses a heating cigarette smoking set (application number CN 202420173618.7), detects the concentration and the temperature of flue gas at the in-process of smoking cigarette to confirm the heating power of heating plate according to flue gas concentration and temperature, with the heating temperature of adjustment heating plate, make flue gas concentration and temperature keep stable, ensure the stability of taste, improve the smoking experience. The Sichuan triple new material limited company and Sichuan middle smoke industry limited liability company disclose a filter stick and a manufacturing method, a preparation system and a heating cigarette (application number CN 202311233159.3) using the filter stick, cellulose paper is added in the filter stick, and the characteristics that the cellulose paper is easy to absorb additional essence, easy to keep immersed matters and can slowly release specific components are utilized, so that the filter stick has the additional essence and also has a filtering function, and after the filter stick is used on the heating cigarette, the stability of the sensory quality of smoke after mouth can be effectively improved. The real-time detection mechanism is added on the smoking set, so that the production and manufacturing cost and the failure rate of the smoking set can be increased, and the method of absorbing and releasing the smoke by using the filter tip belongs to passive regulation, and the regulation effect on the smoke is limited. The above patents have all been proposed for improving the smoking stability of heated cigarettes, and the present utility model has been made based on this object. Disclosure of utility model The utility model provides a heating cavity structure for improving the smoking stability of a heated cigarette, which aims to improve the smoking stability of the heated cigarette by improving the heating cavity structure. The aim of the utility model is realized by the following technical scheme: A heating cavity structure for improving the smoking stability of a heated cigarette comprises a hollow cylinder, wherein the circumferential wall of the hollow cylinder is divided into a heating area and a non-heating area, the heating area and the non-heating area are alternately arranged, a resistance heating mechanism is embedded on the inner wall surface of the cylinder of the heating area, and the non-heating area does not have a heating function. The specific technical scheme of the utility model can be divided into the following three forms: 1) The non-heating area is of a hollow structure, the number of the non-heating areas is 2-5, the non-heating areas are rectangular, the non-heating areas are uniformly distributed on the circumferential wall of the hollow cylinder along the circumference, and the hollow cylinder of the hollow structure is made of metal or nonmetal materials. 2) The circumference wall of the hollow cylinder is uniformly divided into four parts along the radial direction, every two parts are opposite, one pair is a heating zone, the other pair is a non-heating zone, the inner wall surface of the heating zone is embedded with a resistance type heating mechanism, and the hollow cylinder is made of ceramic materials. 3) The circumference wall of the hollow cylinder is axially divided into a plurality of sections of small cylinders with the same height, the small cylinders are alternately arranged into a heating area and a non-heating area, a resistance heating mechanism is embedded on the inner wall surface of the small cylinder of the heating area, and the hollow cylinder is made of ceramic materials.
