  • the transistor switch circuit sends the trigger signal to the microprocessor according to the received signal.
  • the specific circuit structure of the transistor switching circuit is shown in the second embodiment, and is not in this embodiment. Make a statement.
  • the microprocessor controls the battery to supply power to the heating wire according to the received trigger signal, so that the heating wire atomizes the smoke oil to generate smoke.
  • An advantage of the electronic aerosolization control method provided by the third embodiment and the fourth embodiment is that the user does not have a corresponding operation (while touching the first electric conductor and the second electric conductor located on the outer surface of the electronic cigarette) In the case that the first electric conductor and the second electric conductor are disconnected, the electronic cigarette can effectively prevent the electronic cigarette from automatically working when the user does not perform corresponding operations during packaging and transportation.
  • the waste of smoke oil and the unnecessary shortening of the service life of the electronic cigarette can improve safety, and can effectively reduce the probability that the heating wire is falsely triggered to atomize the smoke oil, and if the user wishes to smoke the smoke, Simultaneously touching the first electrical conductor and the second electrical conductor, without the user's suction or pressing operation, reducing the operation steps and difficulty of the user, and improving the user experience of smoking the smoke.
  • the airflow sensing switch is not required to be disposed, the cost of the electronic cigarette is effectively reduced, and the problem that the airflow sensor does not detect the smoking signal and the smoke oil enters the battery component from the airflow passage to cause a short circuit is avoided when the smoking intensity is small. More preferably, when the user smokes the smoke, the first conductor and the second conductor are naturally touched at the same time, which simplifies the step of the user to smoke the smoke, and avoids the situation that the heating wire cannot work without touching.

Abstract

L'invention concerne un circuit de commande de cigarette électronique et un procédé de commande d'atomisation de cigarette électronique comprenant : un premier conducteur et un second conducteur, lesquels premier et second conducteurs sont situés à des emplacements différents sur une surface extérieure de la cigarette électronique ; le second conducteur est connecté électriquement à l'électrode positive d'une batterie (40) ; le premier conducteur est connecté électriquement à une unité de détection de signal (10) : cette unité de détection de signal (10) est connectée électriquement à un microprocesseur (20) ; et un fil chauffant électrique (30) est connecté électriquement au microprocesseur (20). La présente invention évite efficacement le fonctionnement automatique d'une cigarette électronique lorsqu'un utilisateur n'effectue pas une opération correspondante ; et si l'utilisateur souhaite fumer, alors il lui suffit seulement de toucher simultanément le premier conducteur et le second conducteur, sans effectuer une opération d'aspiration ou de pressage, ce qui réduit les étapes de fonctionnement et la difficulté d'utilisation pour l'utilisateur.
