Description

Technical Field

[0001] The utility model belongs to the technical field of experimental models, in particular to a scientific experimental model for simulating spin drying. Background Art

[0002] Principle of centrifugal motion: The motor starts to work after being powered on. The motor shaft drives the basket to rotate, and the water on the paper in the basket is thrown outward due to the centrifugal force generated by the rotation.

[0003] Centrifugal force: a virtual force, a manifestation of inertia, which does not actually exist. It causes a rotating object to move away from its center of rotation. In order for an object to move in a circular motion, the object needs to be subjected to a force pointing to the center of the circle - the centripetal force. If coordinates are established with this object as the origin, it looks like there is a force of the same magnitude and opposite direction as the centripetal force, causing the object to move away from the center of the circular motion. This is the centrifugal force.

[0004] Centrifugal phenomenon: When the force on an object is not enough to provide the centripetal force required for circular motion, it looks as if the centrifugal force is greater than the centripetal force, and the object will move away from the center of the circle. This phenomenon is called "centrifugal phenomenon"

The vibration device is used to vibrate the drying barrel and make the nail polish brush move to the unloading port along the spiral direction of the loading track.
