Description

Static balance adjusting system and method Technical Field The present invention relates to a system and a method for adjusting static balance, and more particularly, to a system and a method for adjusting static balance in the technical field of sacks. Background The inflatable and deflatable air bags, air cushions and the like can be applied to various commodity fields such as cushions, pillows, mattresses and the like, and a valve body is generally connected to the structure of the inflatable and deflatable air bags, air cushions and the like so that the valve body can control the air inlet and the air release of air in the air bags and the air cushions by means of opening and closing of valve ports of the air chambers in the valve body. However, when the air bags and air cushions are used, when the human body such as the head and the body applies pressure to the air bags and air cushions, the valve body only performs the function of air leakage at most, and cannot respond to the pressures (such as the weight of the head and the body) of the air bags and the air cushions, but resists the air pressure of the air bags and the air cushions by the reaction forces of different magnitudes, so that the supportability (namely the hardness) and the height of the air bags and the air cushions cannot be adjusted according to the personal demands, and the range of applied commodities is limited and the practicability is poor. Therefore, the structure and efficacy of the air bag and the air cushion are still not ideal. Disclosure of Invention The invention aims to provide a static balance adjusting system which can adjust the supporting property (namely hardness) and the height of a bag by using static balance.
