Image acquisition mechanism and oral cavity cleaning equipment

The utility model discloses an image acquisition mechanism and oral cavity cleaning equipment, and relates to the technical field of oral cavity cleaning. The image acquisition mechanism comprises an image acquisition member, a light source and a polarization assembly. The image acquisition part comprises a light incident side; the light source is arranged on one side of the image acquisition part in the circumferential direction, the light source comprises a light emitting side, and the light emitting side is located at one end, close to the light incident side, of the light source; the polarization assembly covers the light outlet side and the light inlet side at the same time. The polarization assembly is used for shielding light rays which are directly reflected in the light rays generated by the light source from entering the image acquisition part. The image acquisition mechanism provided by the utility model can solve the problem of bright spots in the image and improve the imaging effect of the image.
