Abstract:
Un sistema (200) para fumar cigarrillos, calentado eléctricamente, que comprende: una unidad (58) calentadora que tiene una abertura (30a) adaptada para recibir un extremo de un cigarrillo,en el que la unidad calentadora está adaptada para aplicar calor a una parte del cigarrillo, y define al menosparte de un conducto de flujo de succión a través del cual el aire ambiente es arrastrado en contacto con elcigarrillo cuando un fumador da una calada al cigarrillo posicionado en la unidad calentadora; un sensor operable para sacar una señal indicativa de que un fumador está dando una calada al cigarrillo; yuna carcasa (20, 22, 24, 26) diseñada para ser agarrada por un fumador; caracterizado porque el sistema comprende además una partición (40) que posiciona la unidad (56)calentadora con relación a la carcasa (20, 22, 24, 26) y que define al menos parcialmente un conducto (42)de flujo de derivación en comunicación de fluido con el aire ambiente que rodea la carcasa, en el que lapartición define además un conducto (44) de desvío de flujo que conduce desde el conducto de flujo dederivación al conducto (32) de flujo de succión y a través del cual el aire ambiente es arrastrado desde elconducto de flujo de derivación cuando un fumador da una calada a un cigarrillo insertado en la abertura de launidad calentadora, y porque el sensor es operable para detectar un flujo de aire en el conducto de desvío de flujo.
Abstract:
An electrical smoking system is disclosed comprising a housing 20,22,24,26, a heater unit arranged within the housing, a power source connected to the heating elements, a bypass flow passage 42 within the housing, the bypass flow passage being in fluid communication with the ambient air surrounding the housing, a suction flow passage 32 within the housing creating a pathway for air to be drawn by a smoker, the suction flow passage being connected to the bypass flow passage through a flow diverting passage so that ambient air passing through the bypass flow passage will only flow into the suction flow passage when the smoker draws on the cigarette, and a sensor operable to detect air flow in the suction flow passage and output a signal indicative of a smoker drawing on the cigarette. Also disclosed is a method of making an electrical smoking system and a method of activating heating in an electrical smoking system.
