Description
Technical Field

In the working principle of the inflator, an internal motor directly drives a crankshaft to rotate, so that the crankshaft drives a connecting rod to enable a piston to reciprocate up and down, thereby causing the volume of a cylinder to change.
In addition, in order to avoid the situation that the object is excessively inflated by the inflator and the object to be inflated bursts or is damaged, the conventional inflator is provided with a pressure gauge and a pressure detector, so that the inflator can inflate an object to be inflated (such as a tire) according to a preset pressure, and when the pressure detector detects that the gas pressure output by the inflator reaches a preset air pressure (namely, inflation pounds), the inflator automatically stops inflating during the inflation process, thereby avoiding the problem of pressure excess caused by the excessive inflation of the object to be inflated.
However, in the current inflator with the capability of detecting pressure, the pressure detector is installed at the outlet end of the inflator; in fact, the pressure value of the air outlet end of the inflator is necessarily larger than the pressure of the object to be inflated (such as a tire); therefore, when the pressure detector detects that the gas pressure outputted by the inflator reaches a predetermined pressure (i.e. pound of inflation), the pressure detected by the pressure detector is the pressure value at the air outlet end of the inflator, and is not the actual pressure value of the object to be inflated (e.g. tire), which inevitably causes a relative drop between the actual pressure of the object to be inflated and the set pressure of the pressure gauge after the object to be inflated is inflated, and consequently, the object to be inflated and the actual inflation pressure are required to be insufficient, and the object to be inflated is used under the condition of insufficient pressure requirement, which may affect the use benefit and safety of the object to be inflated.
