Description

Technical Field

[0002] Also known as a smoke machine or smoke screen applicator, it is a smoke-generating device that uses a mechanical method to release a smoke screen. It is mainly composed of a power system and a smoke agent supply system. There are also those that use the vehicle engine exhaust system as power. According to the way the smoke screen is formed, it is divided into two types: spraying type and heated evaporation type. The spraying type smoke generator directly sends the liquid smoke agent into the atmosphere after pressurization and atomization, and absorbs moisture in the air to form smoke. The heated evaporation type smoke generator is equipped with a neutral high-boiling point liquid smoke agent. The smoke-generating process is to atomize the smoke agent through a nozzle and send it into the high-temperature gas flow generated by the engine system to form a vapor mixture, which is sprayed into the atmosphere and condensed into smoke. The electronic devices in the smoke-generating vehicle often require high voltage to start. Improper operation during the teaching process may lead to students' electrical safety.
