One end of the fixed end rod (3) is connected to a piston of the long cylinder and piston (1), and the other end of the fixed end rod (3) is fixed. The electro-hydraulic servo valves (4, 5) are used to control changes of oil pressures in a left chamber and a right chamber of a cylinder by converting an electrical signal into an oil pressure flow control signal. The force applying end rod (9) is connected to a piston of the short cylinder and piston (2) and the force applying end portion (8). One end of the force applying end portion (8) is connected to the force applying end rod (9) by means of a hinge-connection point, and the other end is connected to a specimen under load test such that large-displacement and high-frequency target displacement is applied to the specimen. The actuator (100) can simultaneously output high-frequency and large-displacement target displacement at 0.1 to 200 Hz and from 0 to 1500 mm, has a simple mechanical structure, an advanced control process, and is practical.

The oil collecting part (1) is provided with an annular oil blocking part and an oil guiding groove (11) connected to the annular oil blocking part, and an inlet of the oil guiding groove (11) is provided in an inner surface of the oil collecting part (1). The connecting part (2) is arranged on the oil collecting part (1) and extends in a direction away from the oil collecting part (1). The annular oil blocking part surrounds the periphery of a filter screen (7), and when the filter screen (7) rotates, oil is ejected out of the filter screen (7) and blocked by the oil collecting part (1). The oil collecting part (1) is annular, and cooking fumes flow and converge along the inner surface of the oil collecting part (1) and finally flow out in a centralized manner through the oil guiding groove (11). The annular oil collecting part (1) has a certain width, such that a shape with openings at two ends is formed, and the connecting part (2) used for being connected to the range hood is arranged on the opening at one end.
