Embodiment 1

[0026] Use as figure 1 The novel cigarette heater with an aerogel heat insulation layer is shown, which includes a housing 1, a heating element 3, a heating cavity 4 formed by the heating element 3, and a heating element 3 and the housing 1 Between the insulation layer 2. The aerogel material used in the thermal insulation layer is bridged silsesquioxane aerogel, and the application form is flexible felt. The aerogel in the outer layer of the thermal insulation layer is filled with 2% volume fraction of montmorillonite- Fatty acid complex. The thickness of the heat insulation layer is 5 mm, and when the temperature of the heating element reaches 600°C, the temperature of the shell is 45°C.

Embodiment 2

[0028] Use as figure 1 The novel cigarette heater with an aerogel heat insulation layer is shown, which includes a housing 1, a heating element 3, a heating cavity 4 formed by the heating element 3, and a heating element 3 and the housing 1 Between the insulation layer 2. The aerogel material used in the heat insulation layer is resorcinol-formaldehyde aerogel with quartz fiber mixed therein, the application form is particles, and a layer of aluminum foil is wrapped on the surface of the aerogel material, and the heat insulation layer is outside The layer of aerogel is filled with 5% by volume of polyethylene glycol 2000. The thickness of the heat insulation layer is 8 mm, and when the temperature of the heating element reaches 600°C, the temperature of the shell is 40°C.

Embodiment 3

[0030] Use as figure 1 The novel cigarette heater with an aerogel heat insulation layer is shown, which includes a housing 1, a heating element 3, a heating cavity 4 formed by the heating element 3, and a heating element 3 and the housing 1 Between the insulation layer 2. The aerogel material used in the heat insulation layer is silica aerogel, and the application form is powder. A layer of aluminum foil is coated on the surface of the aerogel material, and the aerogel on the outer layer of the heat insulation layer is filled with 10% volume fraction of oleic acid. The thickness of the heat insulation layer is 2 mm, and when the temperature of the heating element reaches 600°C, the temperature of the shell is 38°C.

Abstract

The invention discloses a novel cigarette heater provided with an aerogel heat-insulating layer. The novel cigarette heater comprises a shell 1, a heating element 3, a heating chamber 4 formed by the heating element 3, and a heat-insulating layer 2 positioned between the heating element 3 and the shell 1. The novel cigarette heater is characterized in that the heat-insulating material of the heat-insulating layer 2 is aerogel; the heat-insulating layer 2 is partitioned into an inner layer 2-1 and an outer layer 2-2; the inner layer 2-1 is in direct contact with the heating element 3; the outer layer 2-2 is positioned between the inner layer 2-1 and the shell 1; the aerogel porous structure of the outer layer 2-2 of the heat-insulating layer 2 is filled and/or adsorbed with a phase change material. The aim of protecting a user is fulfilled in the presence of the heat-insulating layer; moreover, the heat loss of the heating element can be reduced, and the heat energy utilization ratio is increased.

Description

Technical field [0001] The invention belongs to the technical field of cigarettes, and specifically relates to a novel cigarette heater with a heat insulation layer. Background technique [0002] With the strengthening of the public’s awareness of the dangers of traditional cigarettes and the government’s increasing control of traditional cigarettes, tobacco companies around the world have stepped up the development of new tobacco products, hoping to minimize them while meeting consumer needs. The harm caused by tobacco. Among them, new cigarettes deliver nicotine and flavor to the human body by heating tobacco instead of burning tobacco to roast the flavor substances in the tobacco. They are relatively close to traditional cigarettes in terms of physiological feelings, psychological perceptions, and smoking methods, and are easily consumed by tobacco. People accept it as a new type of tobacco product with great development potential. Therefore, developing new cigarettes and ac...
