The utility model relates to a tire inflation special equipment used for tire production lines and tire maintenance. It is composed of a body and a workbench, and the body includes an inflation device, a deflation device, a detection device, and an electrical control system; The workbench includes a platform above the machine body for placing tires and a control console. In the middle of the platform for placing tires, there are several rotating rollers, and each end has a fixed roller, both fixed on two brackets and connected to the machine body. The entire inflation and deflation process of the inflator is controlled by the control console. This utility model uses a detection device at the end of the inflator, which effectively controls the inflation and deflation amount, Effectively controlling the tire pressure within the specified range, reducing noise during operation, making the entire inflation process easy to operate, the structure of the inflation machine is simple, and multiple air paths can be set. When the air path increases, it does not affect the efficiency of each air path, and the cost of this utility model is low
