Description

Technical Field

[0001] The utility model relates to the technical field of salt spray testing, in particular to a temperature and humidity control mechanism of a salt spray testing machine. Background Art

[0002] Salt spray testing is an environmental test that primarily uses salt spray testing equipment to create artificial simulated salt spray environmental conditions to assess the corrosion resistance of products or metal materials. It is divided into two categories: one is the natural environment exposure test, and the other is the artificial accelerated simulated salt spray environment test. When conducting these tests, a salt spray testing machine is required to spray salt spray on the test product placed inside the machine body to perform corrosion resistance tests. However, the existing technology has the following shortcomings when used:

[0003] When spraying salt mist, a single delivery pipe is often used, which is unable to guide the salt mist entering the machine body. This may cause uneven distribution of salt mist inside the salt spray test machine, affecting the test results of multiple test samples, and needs to be improved.

[0004] Therefore, a temperature and humidity control mechanism of a salt spray test machine is urgently needed to solve the above problems. Utility Model Content
