CN-122004545-A - Real-time temperature control for aerosol delivery devices

Abstract

An aerosol delivery device (100) is provided that includes a housing equipped with a heating element (318), a Resistance Temperature Detector (RTD) (604), and a control component (206). The housing may contain an aerosol precursor composition and the heating element may be controllable to activate and evaporate components of the aerosol precursor composition. The RTD may have a resistance that is variable and proportional to the temperature of the heating element, and may also have a temperature coefficient of resistance that is suitably large enough to be constant with respect to the temperature of the heating element. The control component may be configured to measure a resistance of the RTD and determine a temperature of the heating element from the resistance, and control the at least one functional element in real time based on the temperature so determined, the control of the at least one functional element including outputting the temperature for presentation by the display, or adjusting the power of the heating element.

Description

Real-time temperature control for aerosol delivery devices The present invention is a divisional application of the invention patent application with international application number PCT/IB2017/057059, international application date 2017, 11-10, and application number 201780070046.2 entering the national stage of china, named "real-time temperature control for aerosol delivery device". Technical Field The present disclosure relates to aerosol delivery devices such as smoking articles, and more particularly to aerosol delivery devices that can utilize electrically generated heat to generate aerosols (e.g., smoking articles commonly referred to as electronic cigarettes). The smoking article may be configured to heat an aerosol precursor, which may comprise a material that may be made of or derived from tobacco or otherwise comprise tobacco, which precursor is capable of forming an inhalable substance for human ingestion. Background In recent years, many smoking devices have been proposed as improvements or alternatives to smoking products that require the use of combusted tobacco. Many of the above devices have been said to be designed to provide sensations associated with smoking cigarettes, cigars or pipes without delivering significant amounts of incomplete combustion products and pyrolysis products resulting from the combustion of tobacco. For this reason, many cigarette products, flavor generators, and pharmaceutical inhalers have been proposed that employ electrical energy to evaporate or heat volatile materials or attempt to provide the sensation of smoking a cigarette, cigar or pipe without burning the tobacco to a significant extent. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat sources described in the background art described in U.S. Pat. No. 7,726,320 to Robinson et al and U.S. Pat. No. 8,881,737 to Collett et al, both of which are incorporated herein by reference. See also, for example, U.S. patent publication No. 2015/0216232 to Bless et al, the name of the referenced trademark and various types of smoking articles of commercial origin, aerosol delivery devices, and electric heat sources, which are incorporated herein by reference in their entirety. In addition, various types of electric aerosol and vapor delivery devices are presented in U.S. patent publication Nos. 2014/0096781 to Sears et al, 2014/0283859 to Minskoff et al, and U.S. patent application Ser.
