What is Maglev-driven Negative Pressure Suction?
In operation of the negative pressure sucking massage device, the negative pressure generation unit energizes the metal coil with electricity to generate a magnetic field resulting in: driving the sliding magnet block to reciprocate to form a piston effect, evacuating air to form a negative pressure to produce a sucking effect on the stimulated portion(s) continuously.
Other Sucking Patents
After the drive device physically connected to the flexible wall is energized with electricity, it continuously pulls the flexible wall. Thereby causing a changing volume of the chamber at the other end of the flexible wall. The changing volume of the chamber forms positive and negative pressures on the body part that contacts the open end of the chamber, generating sucking stimulation.
