The utility model discloses an emission device and an emission system for material smell evaluation, and belongs to the field of material smell evaluation. The diffusing device is used for being placed in an air bag and comprises a hollowed-out base and a hollowed-out upper cover, a downward groove is formed in the upper surface of the hollowed-out base, and the hollowed-out upper cover is connected with the hollowed-out base in an opening and closing mode. According to the utility model, the to-be-tested material sample is supported by the diffusion device, is positioned in the diffusion device and is effectively isolated from the air bag, so that pollution caused by contact with the air bag is prevented, the air bag cannot be punctured, the probability that the air bag is punctured or polluted by the sample is effectively reduced, and the service life of the air bag is prolonged. Due to the design of the hollow base and the hollow upper cover, the smell emission of the material sample to be tested is not in
