Patent attributes
A massager with a non-contact driving apparatus includes a machine housing, a driving apparatus, and a positioning seat. The driving apparatus is arranged in the machine housing. The driving apparatus includes a rotating motor, a driving seat, a screw guide seat, and an expansion seat. The screw guide seat is provided with a guide groove, an upper end wall of the screw guide seat is provided with a sealing ring, and the positioning seat is provided with a soft piece. The expansion seat moves back and forth in a closed cavity and conveys positive and negative pressure fluid, thereby the soft piece is forced to swing back and forth. By improving the structure of the driving apparatus, a linear change of the fluid is achieved, and movement intermittency caused by an existing cam mechanism is avoided, so that the movement of the soft piece is softer.
