Set the box 1 controller to rotate the main shaft 13 once within 5S, and the mark of the sphere 14 will disperse and a small sphere will float upward. If there is no action on the main shaft 13 within 5S, it means After a single exercise, mark 14 returns to its initial size, and the floating small sphere is small. The mark is switched based on the number of movements of spindle 13. It should be noted that the energy consumption of a single rotation of spindle 13 for the small ball with fat mark rising is It is converted from calories and its standard value can be easily calculated. It does not involve the protection content of this plan, and again it is not described in detail;

A penetrating heat dissipation through hole 14 is provided on the side wall of the box 1 , and a combined convection duct 5 capable of simultaneous convection of air in and out is provided in the heat dissipation through hole 14 , and is located close to the combined convection duct 5 in the box 1 An active ventilation mechanism 6 is provided at , and the active ventilation mechanism 6 uses the combined convection duct 5 to perform convection ventilation and heat exchange in the box 1 .
