[0037] In the above embodiment, the baffle 5 is movably arranged in the box body 1, and can be moved according to the volume of the part to be detected to adjust the size of the cavity. Therefore, the part to be detected can be placed in the cavity of the box body, and can also be completely immersed in the tobacco protective agent in the cavity, thereby avoiding excessive use of the tobacco protective agent; and the ultrasonic generator 6 can be used to emit ultrasound to ultrasonically mix the tobacco protective agent in the cavity, without the need for operators to contact the tobacco protective agent, thereby improving the safety of the test and realizing the detection of the corrosiveness of the tobacco protective agent to various components.

[0038] The corrosion test device for tobacco protective agents provided in the embodiment of the utility model can be used for corrosion tests of different tobacco protective agents, and can also be used to detect the corrosion resistance of different parts to be tested. Therefore, it can not only quickly screen out tobacco protective agents with good safety performance, but also provide a device for verifying the corrosion of other agents.

[0039] refer to Figure 2 and Figure 3 In some embodiments, there are two baffles 5 , which are arranged opposite to each other, and a space for accommodating the tobacco protective agent and the part to be detected is formed between the two baffles 5 .

[0040] In the above embodiment, the two baffles 5 are relatively arranged in the box body 1. The relative movement of the two baffles 5 can reduce the volume of the cavity. The two baffles 5 move away from each other to increase the volume of the cavity.
