Closed air chamber structure for simulating puff

The utility model relates to a closed air chamber structure for simulating a puff, which is characterized in that a partition plate which transversely moves is arranged in an air chamber, an open-close type through hole structure is arranged on the partition plate, the through hole structure is matched with a valve body structure, the partition plate is driven by a non-contact type driving device to reset after being driven, and the puff can be simulated through the action of the partition plate. According to the utility model, after gas is injected into the gas chamber, the partition plate is pushed to one end of the exhaust valve, so that the air in the gas chamber is quickly exhausted, and the movable partition plate is arranged in the gas chamber, so that original gas in the gas chamber can be quickly exhausted by standard gas; the influence on the environment due to the fact that part of standard harmful gas is exhausted through the exhaust valve after being introduced for a long time is avoided, the gas
