A sensor apparatus may include a channel structure configured to couple with an external element and a fluid conduit, such that the channel structure may receive a fluid, at least partially drawn through the external element from an ambient environment, and direct the fluid through the fluid conduit. A sensor may generate sensor data indicating a flow rate of the fluid through the fluid conduit based on monitoring a variation in a pressure at a location in hydrodynamic contact with the fluid conduit and in relation to an ambient pressure of the ambient environment. The sensor apparatus may enable generation of improved topography information associated with flows of fluid drawn from the external element based on measuring a local pressure at the location in hydrodynamic contact with the fluid conduit and determining the ambient pressure based on monitoring the local pressure over time.

An apparatus for collecting emissions from a device, the apparatus includes an inlet which receives emissions from a device; an outlet for a collecting assembly; and a pump assembly which includes a pump, the pump being in fluid communication with the inlet and operable to draw emissions from the inlet to the outlet for the collecting assembly. The pump assembly is configured such that, in use, emissions are drawn from the inlet intermittently. A collecting assembly may collect and condense the emissions by employing low temperatures.

The present disclosure relates to a colorimetric aerosol detection device for detecting target compounds in an aerosol generated from an aerosol delivery device. The colorimetric aerosol detection device includes a tubular housing with a first open end and a second open end such that a stream of vapor can pass through the tubular housing in a direction from the first end to the second end. The first open end is configured to engage a mouthpiece of the aerosol delivery device and the second open end is configured as a mouthpiece through which a user can draw a stream of vapor generated by the aerosol delivery device into the tubular housing by suction. A colorimetric indicator material is located inside the tubular housing configured to signal detection of a target compound in the vapor stream by a change in color visible to the user through a transparent or translucent portion of the tubular housing.

A thermal measurement system includes a thermocouple configured to couple to a location of a heating element of an electronic smoking article. The thermocouple is structured to measure a surface temperature of the location. A thermocouple data module is operatively connected to the thermocouple and is structured to receive data of the surface temperature from the thermocouple. A pneumatic system is configured to connect to an end of the electronic smoking article and draw an air flow through the electronic smoking article. The pneumatic system includes a solenoid valve having an open state that causes air to flow through the electronic smoking article. The solenoid valve has a closed state that prevents air flow through the electronic smoking article. An infrared camera is disposed over the viewing window. The infrared camera is configured to measure a wire temperature of a heating element wire of the electronic smoking article.

This specification generally discloses a system and method configured to generate vapor samples from one or more smoking articles used for testing purposes. The system may be configured in a manner that reduces the likelihood of exposing particular mechanical components to the smoking article vapor, which may in turn reduce effects of fouling or corroding such components of the system over a period time.

The invention discloses a method for evaluating the aerosol mass of electronic cigarettes, comprising the following steps: (1) Measurement: an electronic cigarette is smoked to measure the particle size distribution and the particle numbers in the generated aerosol, and measure the volume flow rate C of the aerosol and the testing time t; (2) Data processing: based on the particle size distribution and number, the aerosol particles are classified with classifying diameter d.sub.i, and the corresponding average number concentrations n of the particles to classifying diameters d.sub.i are calculated; and (3) the generated aerosol mass is calculated according to the calculation formula for the aerosol mass of the invention.

The present invention provides a smoking machine for an electronic cigarette, relating to the technical field of electronic cigarettes. The smoking machine for an electronic cigarette comprises: a housing; a rotary disc installed on a side surface of the housing, a central axis of the rotary disc is parallel to a horizontal plane, and the rotary disc rotates relative to the housing with the central axis of the rotary disc as a center, a disc-body smoking through hole is provided on an end face of the rotary disc, a housing sealing member is disposed on a side surface of the housing, a sealing ventilation hole penetrating into the housing in a horizontal direction is provided in the housing sealing member, and an end face of the housing sealing member is in contact with the end face of the rotary disc; and a main control circuit board electrically connected to the rotary disc. The rotary disc of the present invention is perpendicular to a horizontal plane, and the electronic cigarette circumferentially rotates along with the rotary disc in a smoking experiment process, so that tobacco tar in a cigarette cartridge flows and fully immerses the oil guiding cotton, thus ensuring sufficient and steady supply of the tobacco tar to an atomizer, and guaranteeing atomization efficiency, atomization amount, and the stability and accuracy of experiment data.

A test fixture for testing aerosol provision devices may include a housing, a plurality of testing modules disposed at the housing where each of the testing modules includes a cavity configured to receive a portion of an aerosol provision device, and processing circuitry operably coupled to the testing modules.
