Description
Technical Field
[0001] The utility model relates to the technical field of salt spray test instruments, in particular to a salt spray test device. Background Art
[0002] Salt spray test equipment is used to simulate salt spray environment to test the corrosion resistance of products or metal materials. Salt spray test equipment can be divided into two categories: natural environment exposure test and artificial accelerated simulated salt spray environment test. Among them, the artificial accelerated simulated salt spray environment test uses a test equipment with a certain volume space - a salt spray test chamber, and uses artificial methods in its volume space to create a salt spray environment to assess the salt spray corrosion resistance quality of the product.
[0003] Most of the existing salt spray test devices adopt a closed design, and manual operations are required during the test, such as adding salt and controlling temperature, which not only increases the complexity of the test, but also affects the accuracy and reliability of the test.

However, after understanding the disclosure of the present application, various changes, modifications and equivalents of the methods, devices and / or systems described herein will be apparent. For example, the order of operations described herein is merely an example, and is not limited to the order set forth herein, but in addition to the operations that must occur in a particular order, changes that will be apparent after understanding the disclosure of the present application may be made. In addition, in order to improve clarity and brevity, descriptions of features known in the art may be omitted.
[0025] The features described herein may be implemented in different forms and should not be interpreted as being limited to the examples described herein. Rather, the examples described herein have been provided only to illustrate some of the many possible ways of implementing the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.
[0026] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, “bound to”, “over”, or “covering” another element, it may be directly “on”, “connected to”, “bound to”, “over”, or “covering” another element, or one or more other elements may be present between them. In contrast, when an element is described as being “directly on”, “directly connected to”, “directly bound to”, “directly over”, or “directly covering” another element, there may be no other elements present between them.
[0027] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.
[0028] Although terms such as "first", "second", and "third" may be used herein to describe various components, assemblies, regions, layers, or portions, these components, assemblies, regions, layers, or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, component, region, layer, or portion from another component, component, region, layer, or portion. Therefore, without departing from the teachings of the examples described herein, the first component, component, region, layer, or portion referred to may also be referred to as the second component, component, region, layer, or portion.
[0029] For ease of description, spatial relative terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another element as shown in the drawings. Such spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the drawings. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element would then be located "below" or "lower" relative to the other element.
[0030] Therefore, the term "above" includes both "above" and "below" orientations depending on the spatial orientation of the device. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein will be interpreted accordingly.
