AUTOMATIC CONTROL METHOD OF INFLATION
First Claim
1. An automatic control method of inflation comprising the steps of:
- A. starting inflation;
inflating an inflated object through an inflator hose connecting an inflator and the inflated object until a gauge of the inflator reaches an initial set pressure value and the inflator having a microprocessor;
when a pressure sensor in the pressure gauge connected to the inflator hose detects the pressure has reached an initial set pressure value [pset], the pressure sensor sends a signal back to the microprocessor so that the microprocessor controls and makes an air pump stop inflation;
B. waiting for pressure balance;
after short shut-down of the inflator, the pressure in the inflated object and the pressure in the inflator hose of the inflator get balanced;
the pressure sensor in the pressure gauge immediately detects an actual pressure value [pb] after the balance and sends the actual pressure value [pb] after the balance to the microprocessor.C. calculating a compensation value;
a compensation value [pfix] is calculated and obtained according to a built-in program of the microprocessor;
the initial set pressure value [pset] minus the actual pressure value [pb] after the balance is equal to the compensation value [pfix];
then adding this compensation value [pfix] with the initial set pressure value [pset] to get a new set pressure value [pn] the inflated object actually needs.D. completing inflation;
the microprocessor drives the air pump to output air with corresponding pounds weight according to the new set pressure value [pn] obtained so that the inflation process is completed.

Abstract
An automatic control method of inflation is revealed. An inflator including a pressure gauge with a microprocessor automatically controls an inflated object to be inflated until the pressure reaches an initial set pressure value on the pressure gauge. After the pressure reaching the initial set pressure value, an air pump of the inflator is shut down until the pressure gets balanced. Now the value shown on the pressure gauge is lower than the initial set pressure value. The difference between an actual pressure value and the initial set pressure value is calculated and is added with the initial set pressure value to get a new set pressure value the inflated object actually needs by the microprocessor. Now the inflator starts inflation again until the pressure reaches the new set pressure value. The inflation is completely precisely.
