In addition, the air jet head 20 is rotatably arranged on the base 10. The air jet head 20 comprises a main body 21, an air jet dust removal part 22 arranged on different end faces of the main body 21, and two air jet driving parts 23. In this embodiment, the main body 21 is in a cylindrical shape, the air jet dust removal part 22 is located on the top end face of the main body, and the two air jet driving parts 23 are located on the outer circumferential side face of the main body. The main body 21 is provided with an air flow channel 211 connected to the air inlet channel 102. The air flow channel 211 is a large-diameter channel to ensure sufficient air flow.

[0048] The air jet dust removal part 22 is provided with a dust removal air jet port 221 connected to the air flow channel 211. The dust removal air jet port 221 is a narrow and thin opening structure to ensure that the speed of the ejected gas is fast enough, so that the impact force on the VR lens barrel 1 is larger, that is, the dust can be lifted up.

[0049] Two said jet drive parts 23 are symmetrically arranged on the main body part 21, each jet drive part 23 is provided with a jet drive hole 231 which is connected with the airflow channel 211, the jet directions of the two jet drive holes 231 are opposite, the jet drive hole 231 is a small-diameter hole structure, the airflow jetted from the two jet drive holes 231 can provide strong thrust to the jet head 20, and since the jet directions of the jet drive holes 231 are opposite, the airflow thrust can drive the jet head 20 to rotate on the base 10, without the need of a motor to provide rotating driving force, so that self-rotating jet dust removal can be realized, the production cost is saved, the occupied space of the device is smaller, and thus the device is more suitable for dust removal of small-volume objects.

[0050] In operation, the dust removal jet port 221 jets airflow to blow up dust in the inner cavity of the VR lens barrel 1, the airflow jetted from the two jet drive holes 231 provides thrust to the jet head 20 to drive the jet head 20 to rotate, so that multi-directional airflow blowing and dust removal are realized for the inner cavity of the VR lens barrel 1, and the blown-up dust is sucked away from the dust suction channel 101 under the action of the negative pressure device. In one embodiment, the dust in the inner cavity of the VR lens barrel 1 is mainly blown up by the airflow jetted from the dust removal jet port 221; in another embodiment, the dust in the inner cavity of the VR lens barrel 1 can also be blown up by the airflow jetted from the dust removal jet port 221 and the two jet drive holes 231.
