Problems solved by technology

[0003] At present, the commonly used heating elements of heat-not-burn cigarettes are thick-film ceramic-based heating elements or metal-based heating elements. Due to their small individual size, the thickness is generally only 0.35-0.55mm. In the process of smoking or cleaning, If used improperly, it is easy to cause the heating element to break and be damaged. Therefore, before applying the corresponding heating element, the mechanical strength performance of the heating element must be fully evaluated.
However, there is currently no mechanical strength test device specifically for heating elements in heated cigarette smoking utensils

Description

technical field [0001] The invention belongs to the technical field of heating cigarettes, in particular to a device for testing the mechanical strength of a miniature heating element and a testing method for testing the mechanical strength of the heating element by using the device. Background technique [0002] With the strengthening of tobacco control efforts in countries around the world, the tobacco industry has entered a new period of demand change and breakthrough, which has promoted and accelerated the development of new cigarettes. Heat-not-burn cigarettes have quickly become a hot topic in the tobacco industry due to their "high technological content and high user conversion rate". Electric heating and non-burning cigarettes are composed of a heating device and a cigarette. The heating element is the core component of the heating device, and its performance directly determines the quality of the heating device. [0003] At present, the commonly used heating elemen...
