Balloon inflator

A balloon inflator (10) includes a housing (12), a motor (20) within the housing (12), and a fan (22) operable by the motor (20) to drive air to an inflation nozzle (17). The inflation nozzle (17) provides an outlet. A nozzle adaptor (50c) is configured to fit over the outlet of the inflation nozzle (17) and provide an alternate outlet. A nozzle receipt (54c) is provided by the housing to selectively receive the nozzle adaptor (50c) and a switch (64) is provided at the nozzle receipt (50c). The nozzle adaptor is selectively received at the nozzle receipt so as to trigger the switch (64), and is selectively removed from the nozzle receipt so as to not trigger the switch. The switch controls the power supplied to the motor (20), such that different motor operating parameters are realized when the switch (64) is triggered and when the switch is not triggered. In a particular embodiment, the nozzle adaptor (50c) includes vent channels that exhaust a portion of the air to the atmosphere when a balloon is fitted over the alternate outlet to receive air driven through the nozzle and the nozzle adaptor.
