[0002] Smoking is harmful to health, especially smoking indoors or in public places. It not only harms the smoker himself, but also pollutes the environment with the smoke and ash produced, and also harms the people around him. In recent years, various environmentally friendly smoking appliances or devices have appeared on the market, among which electronic cigarettes are particularly prominent. Depending on the atomization source, electronic cigarettes can be divided into many forms, such as atomizing e-cigarettes with oil, atomizing e-cigarettes with paste, and burning tobacco.

[0003] At present, the tobacco-burning electronic cigarettes on the market generally use heating ceramics with built-in heating wires or heating wires for heating. This method has a slow heating speed, and the heating wire is in direct contact with the tobacco, which is easy to produce substances harmful to the human body, and there is a problem of not being environmentally friendly. At the same time, the ceramic heating element has a relatively complex structure and high processing cost. In addition, long-term contact with the cigarette cartridge will cause the heating element to be smoked black, have residues, easily produce odor, and be difficult to clean. The appearance is not beautiful enough, and it will also affect the user's experience when using it. To this end, the inventor designed a double-layer glass heating element to solve the above problems. Utility Model Content

[0013] 1. The utility model provides a double-layer glass heating element, which consists of a glass body, a heating net, a conductive wire and a quartz sheet. The overall structure is simple and the design is reasonable. The heating net is arranged at the lower end of the glass body and forms a cavity structure with an opening at the upper end and a hollow interior with the glass body. The glass body consists of an inner glass body and an outer glass body. A sealed accommodating cavity is formed between the inner glass body and the outer glass body. The heating net is arranged in the accommodating cavity, and the heating net is in contact with the inner wall of the accommodating cavity. The heating net is composed of a plurality of heating wires arranged in horizontal and vertical directions, and generates heat evenly. At the same time, the heat emitted is transferred to the smoke bomb through the glass body to achieve the purpose of atomization. Compared with traditional ceramic heating element heating, the heating element has a simple structure, low cost, fast heating speed, and the heating net does not need to be in direct contact with the smoke bomb, so the heating element will not be smoked black.
