ADAPTOR DEVICES FOR USE IN EMISSIONS TESTING OF SMOKING OR VAPING PRODUCTS AND METHODS OF USE

原文（中国語）

A smoking machine adaptor device including a base configured to couple to a smoking machine, the base defining a central axis and a base cavity, a cap including a cap flange defining a cap aperture, and a cap actuator coupled to the base and configured to move the cap flange relative to the base along the central axis between a first position to a second position, and a resiliently deformable ferrule sized to be received within the base cavity and defining a ferrule aperture aligned axially with the cap aperture along the central axis. The ferrule aperture defines a. first ferrule area in a plane perpendicular to the central axis when the cap flange is in the first position, a. second, smaller ferrule area in the plane perpendicular to the central axis when the cap flange is in the second position.
