    摘要: Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented substances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.
