In other embodiments, steps S101 to S105 may be performed in two identical containers, respectively, to obtain third concentration data A3 of the gas in the first container; in steps S106 to S107, the deodorizing efficiency of the deodorized object at time t1 is calculated to be (A3-A4)/A3 × 100% from the fourth concentration data A4 of the gas in the second accommodating tank.
According to the embodiment of the invention, the odor object and/or the deodorant object are/is placed in the accommodating box, the odor gas emission of the odor object in the closed space and the deodorization process of the deodorant object are simulated, and the deodorization process is standardized to evaluate the deodorization effect of the deodorant object.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
