Problems solved by technology

[0002] At present, the heating element of electronic cigarettes on the market generally does not have a temperature control function, so the heating temperature of the smoking substance cannot be controlled, that is, it cannot prevent the production of tar or other toxic substances due to excessive heating temperature, which makes it easy for users to inhale these toxic substances. Substances increase the harm of smoking electronic cigarettes, and the uncontrollable heating temperature will affect the user's smoking taste and reduce the user experience

Embodiment 1

[0019] see Figure 1 to Figure 4 , an electronic cigarette heating element, an electronic cigarette heating element, including a sheet-shaped substrate 1 and a heating element 2 arranged on the surface of the substrate 1; also includes a temperature sensor 3 arranged on the surface of the substrate 1, the surface of the temperature sensor 3 Covered with a protective heat-conducting layer (not shown in the figure), the material of the heat-conducting layer has a temperature resistance of ≥250°C; during the heating process of the heating element of the electronic cigarette, the change in resistance value of the heating resistance X≤50%; the change in resistance value X =|(R1-R2) / R1|, where R1 is the resistance value of the heating element after the temperature rises, R2 is the resistance value of the heating element at room temperature, the room temperature refers to the environment of 20℃-28℃, the heating element and the electronic The smoke control circuit board (not marked in...

Embodiment 2

[0026] The main difference between this embodiment and Embodiment 1 is that the temperature sensor is an independent temperature sensor, which is fixed on the surface of the substrate by welding or a fixed structure, wherein the temperature sensor is placed on the surface of the substrate opposite to the heating element On one side; preferably, the temperature sensor is arranged along the insertion track of the substrate. Other technical features of this embodiment are the same as those of Embodiment 1, and will not be described in detail here.

Abstract

The invention provides an electronic cigarette heating element, which comprises a base body, a heating element arranged on the base body, and a temperature sensor for detecting a surface temperature of the heating element, wherein a surface of the temperature sensor is provided with a protective heat conducting layer which is made of materials with temperature resistance of more than or equal to 250 DEG C, in a heating process of the heating element, a change amount X of a resistance value of the heating element is less than or equal to 50%, the change amount X of the resistance value is equalto |(R1-R2) / R1|, wherein R1 is the resistance value of the heating element after the temperature is increased, and R2 is the resistance value of the heating element at the room temperature of 25 DEGC. By the adoption of the electronic cigarette heating element, the temperature sensor is additionally arranged, so that a function of temperature controllability is achieved; and meanwhile, a high-temperature-resistant protective heat conducting layer is arranged, so that the heating element is prevented from being oxidized, friction of an adherend after the electronic cigarette is sucked is resisted, heat is better transferred, the heating effect of the heating element is improved, the heating temperature of smoke substances is controlled, and other toxic substances such as tar and the likeare prevented from being generated, thereby reducing harm of users for sucking electronic cigarettes, and ensuring the taste of the users for sucking the electronic cigarettes.

Description

technical field [0001] The invention relates to the technical field of electronic cigarette appliances, and mainly relates to an electronic cigarette heating element with a temperature sensor. Background technique [0002] At present, the heating elements of electronic cigarettes on the market generally do not have a temperature control function, so the heating temperature of the smoking substance cannot be controlled, that is, it cannot prevent the production of tar or other toxic substances due to excessive heating temperature, making it easy for users to inhale these toxic substances. Substances increase the harm of smoking electronic cigarettes. In addition, the uncontrollable heating temperature will affect the user's smoking taste and reduce the user experience. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an electronic cigarette heating element with temperature control function. ...
