FRAGRANCE CARTRIDGE FOR A DIGITAL ODOR GENERATOR

摘要

A fragrance cartridge for use with a digital odor generator includes a two part cylindrical metal housing having an outer cylindrical surface and an inner cavity capable of containing an odorant. The two parts are removably secured together in order to gain access to the inner cavity. The housing has an opening adjacent each end, with each opening being in communications with the inner cavity. Air can pass through one of the openings into the cavity to mix with the odorant and can then exit the cavity through the other opening. The outer surface includes two circular grooves and an O-ring is located in each groove. A one-way valve is located adjacent each end of the cavity. One of the valves allows air to pass into the cavity from a first end and the other valve allows air to pass out of the cavity from the second end.
