An electronic cigarette temperature detection method and its special detection device

Abstract

The invention discloses an electronic cigarette temperature detection method and a special detection device thereof. It adopts a measurement method combining an infrared probe and a fine thermocouple to measure the surface temperature of the heating wire of the electronic cigarette, the radial temperature distribution of the atomization area, and the temperature distribution of the atomization area. The axial temperature distribution is detected, collected and stored through a data acquisition system electrically connected with an infrared probe and a micro-thermocouple, and then the surface temperature of the heating wire and the temperature distribution of the flue gas formed in the atomization area are obtained. The present invention respectively measures the axial and radial temperature distributions of the electronic smoke chamber and the surface temperature of the heating wire of the electronic cigarette through axial thermocouples, radial thermocouples and infrared probes, and can establish the relationship between the temperature of the heating wire and the temperature of the mainstream smoke. The relationship between them provides support for the rational design of the e-cigarette heating system. The temperature detecting device of the present invention solves the difficult problem in detecting the temperature of the mainstream smoke of electronic cigarettes, has high data collection frequency, and can objectively and truly restore the temperature change process.

Description

technical field [0001] The invention relates to a temperature detection method, in particular to an electronic cigarette temperature detection method and a special detection device thereof. Background technique [0002] With the diversification of consumers' demand for cigarette products, various products imitating cigarettes continue to emerge, especially the development of electronic cigarettes is the most rapid. At present, there are integrated and split types of electronic cigarettes on the market. The integrated electronic cigarette oil, battery, and resistance wire cannot be replaced, and the split type electronic cigarette oil, battery, and resistance wire can be replaced. It is suitable for electronic cigarettes. The quality evaluation method needs to cover the two parts of the atomizer module and the e-liquid that affect the atomization of e-liquid in order to comprehensively and accurately evaluate the sensory quality of e-cigarettes. At present, there is no senso...

Problems solved by technology

[0005] To sum up, the temperature measurement of the e-cigarette vaporization area has been adopted in some e-cigarette designs, but the temperature measurement method usually uses a contact single-point measurement of the temperature of the heating device. Since the heating device has a certain surface area and the temperature distribution is uneven, This measurement method cannot obtain detailed temperature characteristics of the atomization area, which brings difficulties to the fine design of the product and the in-depth study of the characteristics of the atomization by researchers.
