Abstract
An inflation system includes a base, an adjuster and a first sealing device. The base is provided with a receiving cavity, an air inlet and an inflation inlet, the adjuster is rotatably configured in the receiving cavity, and the first sealing device is adapted for sealing the inflation inlet. The adjuster is turnable between a communication position and a separation position to open or close the inflation inlet, at the communication position, the first sealing device is openable under an action of high pressure air to communicate the inflation inlet with the air inlet; at the separation position, the adjuster stops high pressure air from opening the first sealing device thereby separating the inflation inlet from the air inlet. Different air passages can be selected in the invention, and the usage is convenient and safe.
