US Patent 11833102 Sexual stimulation massage apparatus

Embodiments of the present disclosure disclose a sexual stimulation massage apparatus. The massage apparatus includes a body, and a reciprocating motion structure is disposed within the body. The reciprocating motion structure includes a rotational structure and a linear motion structure that are mechanically coupled with each other. A motor includes a rotating shaft which is mechanically coupled with the rotational structure to rotate the rotational structure. The reciprocating motion structure imparts a reciprocating motion to the linear motion structure. A stimulating structure is operatively coupled with the linear motion structure. The stimulating structure is configured to contact with a human body and provide sexual stimulation to the human body based on the reciprocating motion of the linear motion structure. A power source is configured to provide electric power to the motor for rotating the rotating shaft. A controller is configured at least to control the operation of the motor.
