Description

Technical Field

[0001] This utility model relates to the field of sand and dust testing technology, and more specifically, it relates to a sand and dust environment simulation test chamber. Background Technology

[0002] Dust testing is a reliability test simulating a dusty environment, primarily used to evaluate a product's dustproof sealing performance and operational stability. This test is divided into different levels according to standards (such as IEC 60529, GB / T 4208), such as IP5X (dustproof) and IP6X (dust-tight). During the test, dust concentration, wind speed, and test time must be controlled. It is suitable for industries such as automotive, electronics, and military, ensuring that equipment can still operate normally in dusty environments and preventing dust intrusion that could lead to malfunctions. After the test, it is necessary to check whether dust has entered the equipment and assess whether its protective capabilities meet design requirements.

[0003] In most existing sand and dust test chambers, the testing equipment or components are placed directly on the test platform when testing the equipment. For example, the environmental test chamber with controllable temperature and sand and dust concentration provided in Chinese patent document CN219978094U is a sand and dust test chamber. However, the sand outlet in the sand and dust test chamber is mostly fixed, which makes it inconvenient to adjust the test height and angle of the test equipment. This can easily lead to poor test comprehensiveness of the equipment and affect the flexibility and comprehensiveness of the equipment's wind and sand resistance effect.

[0004] Furthermore, existing sand and dust test chambers are not convenient for automatically collecting and recycling sand that enters the chamber, requiring manual feeding and thus lacking ease of use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a simulated sand and dust environment test chamber to solve the technical problems mentioned in the background art, such as the poor flexibility of the test angle and height of the equipment in the existing simulated sand and dust environment test chamber.
