Micropump for an aerosol delivery device

A control body for an aerosol delivery device, the control body comprising:

• a housing enclosing a reservoir configured to retain an aerosol precursor composition;
• a first power-source terminal configured to connect a power source to the control body;
• heating-element terminals configured to connect a heating element to the control body, the heating element being configured to convert electricity to heat and thereby vaporize components of the aerosol precursor composition;
• a switch coupled to and between the first power-source terminal and the heating element;
• a micro-pump terminal configured to connect a micro pump to the control body, the micro pump being arranged to be operable between the reservoir and the heating element to deliver aerosol precursor composition from the reservoir to the heating element;
• a driver circuit including a boost converter coupled to and between the first terminal and the micro pump, the driver circuit being configured to drive the micro pump via the boost converter;
• and
• a control component including processing circuitry configured to switchably control the driver circuit to drive the micro pump to deliver the aerosol precursor composition to the heating element, the processing circuitry also being configured to switchably control the switch to connect the power source to the heating element independently of the driver circuit and thereby power the heating element independently of the boost converter to vaporize components of the aerosol precursor composition.
