The magnetic levitation piston technology has a large air volume and is not easy to be lost; it relies on the magnetic field to generate kinetic energy and cooperates with the air chamber to create a powerful air volume; the air outlet is enlarged, the bubbles are uniform and natural, and the oxygenation effect is sustained and stable. Soft anti-shock pads keep the body stable and reduce vibration noise. The diverter adjusts the air volume and the diverter valve design allows for more air circulation;
