Aerosol delivery device/system

Abstract

Disclosed is an aerosol delivery device ( 102 ), engageable with a component ( 104 ) for containing an aerosol precursor. The device ( 102 ) comprising a controller ( 120 ) for controlling an operation of the device ( 102 ), an airflow sensor ( 213 ) and a user input device ( 227, 226 ) concealed within a chamber ( 211 ) of the aerosol delivery device ( 102 ). The user input device ( 227, 226 ) is configured to provide, when actuated, a control signal to the controller ( 120 ). The device ( 102 ) also comprises an opening ( 212 ) to the chamber ( 211 ) providing fluid communication between the chamber ( 211 ) and an airflow passage ( 236 ). The opening ( 212 ) arranged such that the user input device ( 227, 226 ) is actuatable by insertion of a pin through the opening ( 212 ).

1 . An aerosol delivery device, engageable with a component for containing an aerosol precursor, the device comprising:
 a controller for controlling an operation of the device;   an airflow sensor and a user input device concealed within a chamber of the aerosol delivery device, the user input device configured to provide, when actuated, a control signal to the controller, and   an opening to the chamber providing fluid communication between the chamber and an airflow passage, the opening arranged such that the user input device is actuatable by insertion of a pin through the opening.   
     
     
         2 . An aerosol delivery device according to  claim 1  wherein the opening is configured to prevent access to the user input device through the opening by a user's finger. 
     
     
         3 . An aerosol delivery device according to  claim 1  wherein the opening has a width that is less than 5 mm. 
     
     
         4 . An aerosol delivery device according to  claim 1  wherein the user input device is aligned on a line of sight extending through the opening. 
     
     
         5 . An aerosol delivery device according to  claim 4  wherein the user input device is arranged such that an axis extending through the opening, and that is normal to the opening, extends through the user input device. 
     
     
         6 . An aerosol delivery device according to  claim 1  wherein the controller is configured, upon receipt of the control signal from the user input device, to adjust one or more device settings, for example, to revert the one or more device settings to a previous state. 
     
     
         7 . An aerosol delivery device according to  claim 1  wherein the user input device comprises a switch. 
     
     
         8 . An aerosol delivery device according to  claim 7  wherein the switch is a press button. 
     
     
         9 . An aerosol delivery device according to  claim 7  wherein the user input device comprises an actuating arm for actuating the switch. 
     
     
         10 . An aerosol delivery device according to  claim 9  wherein the actuating arm comprises a proximal end mounted in the chamber and a distal end extending over the switch. 
     
     
         11 . An aerosol delivery device according to  claim 10  wherein the distal end is cantilevered from the proximal end. 
     
     
         12 . An aerosol delivery device according to  claim 9  wherein the actuating arm is formed of a resilient material. 
     
     
         13 . An aerosol delivery device according to  claim 1  comprising a transversely extending interface wall having a first side at least partly defining the airflow passage and a second side at least partly defining the chamber, the opening to the chamber being formed in the interface wall. 
     
     
         14 . An aerosol delivery device according to  claim 1  comprising a transversely extending printed circuit board (PCB) defining a base of the chamber, the switch supported on the PCB. 
     
     
         15 . An aerosol delivery system comprising a device according to  claim 1  and a component for containing an aerosol precursor.
