[0002] The sand and dust test is mainly used for sand and dust simulation detection of low-voltage electrical appliances, motors, instruments, meters, electronic products, and lamps. It is to evaluate the resistance of all mechanical, electronic, electrochemical, and electromechanical equipment to dry sand or dusty atmosphere and whether they can be stored and operated. However, after the existing sand and dust test, the dust cannot be effectively recovered, resulting in the need to waste manpower to clean it up. Therefore, it does not meet the existing needs. The dust recovery component is one of the important components of the sand and dust test device.

[0003] However, the current dust recovery components still have some shortcomings. For example, the existing dust recovery components are not easy to perform multiple filtration and recovery of dust, which makes it easy for fine dust to enter the inside of the fan and affect the service life of the fan, resulting in a decrease in the practicality of the dust recovery components and a decrease in their use efficiency, resulting in certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides a dust recovery component and a dust test device. Utility Model Content
