It places the items to be tested in the chamber and measures various parameters and release amounts under the simulated environmental conditions in the chamber. Compared with the actual indoor environment, the temperature, humidity and ventilation frequency of the environmental chamber are easier to control manually, and under sealed conditions, it can ensure that the experimental process in the chamber is not affected by outdoor environmental pollution. In order to better monitor the environmental air quality in the simulation chamber, an air quality monitor is installed in the simulation chamber to monitor the internal ambient air in real time. However, the existing simulation chamber has the following problems during use:

10. The method for using the ambient air quality monitoring simulation cabin according to claim 4, characterized in that: The following steps are involved: Step A: When in use, the staff manually opens the door (19) in advance, places the air purifier to be tested into the interior of the simulation cabin shell (1), then closes the door (19), starts the air pump (17) to extract the pollution source pre-placed in the storage box (18), and transports it to the interior of the nozzle (3) through the air delivery hose (16), and then discharges it into the interior of the simulation cabin shell (1) through the nozzle (3), so that the simulation cabin shell (1) simulates a specific ambient air, which is convenient for the subsequent test of the air purifier; Step B: During the operation, the reciprocating assembly (5) on the simulation cabin shell (1) is arranged to drive the nozzle (3) to move back and forth in the simulation cabin shell (1), so that the polluted air is evenly released inside the simulation cabin shell (1) and fills the internal space of the simulation cabin shell (1), and then the air pump (17) is turned off to stop releasing the pollution source. During the test, the air purifier to be tested is placed in the simulation cabin shell (1) to start the polluted ambient air in the simulation cabin shell (1), and at the same time, the air quality detector (4) installed on the simulation cabin shell (1) monitors the ambient air in the simulation cabin shell (1) in real time and provides data for the staff to observe and record; Step C: After the test operation is completed, in order to improve the accuracy of the monitoring data of the air quality detector (4), it is necessary to ventilate the internal environment of the simulation cabin shell (1). By using the mutual cooperation of the reciprocating component (5) and the ventilation component (6), the kinetic energy generated by the operation of the reciprocating component (5) is fully utilized, so that the air outside the simulation cabin shell (1) enters the interior of the simulation cabin shell (1) through the ventilation port (7) to obtain fresh air, thereby realizing the calibration operation of the air quality detector (4). The external environment air contains dust and foreign matter. The dustproof net (8) arranged in the ventilation port (7) can filter the dust and foreign matter in the air to avoid polluting the internal environment of the simulation cabin shell (1). The cleaning component (9) arranged on the ventilation component (6) can automatically clean the dust and foreign matter accumulated on the dustproof net (8) through the cooperation between the ventilation component (6) and the cleaning component (9).
