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.

Abstract: An electric inflator for connecting and inflating an inflatable device includes a shell, a drive motor configured on the axis of the shell, at least one air bag is configured in the shell and around the drive motor, an air outlet of the air bag connected to an inflatable device, and a pressing mechanism connected to an output portion of the drive motor. The air bag is pressed by the pressing mechanism driven by the drive motor for supplying air to the inflatable device. An inner space of the shell can be fully utilized thereby the size of the electric inflator is smaller than before. At the same time, an inner cavity of the air bag can be bigger than before to improve inflating efficiency, which increases portability and practicability of the electric inflator and the inflatable device equipped with the electric inflator.

Abstract: An inflation device includes an airbag and an air valve. An air inlet is provided at an upper end of the air valve, an air outlet is provide at a lower end of the air valve, an inlet valve that is unidirectionally opened. inwards the air valve is provided at the air inlet, the inlet valve can be opened to a deflation position, an outlet valve is provided at the air outlet that is unidirectionally opened outwards the air valve, a push aim extending towards the outlet valve is configured in the air valve and is movable up and down, the push arm is actuated to move towards the outlet valve if the inlet valve is opened, and is pressed against the outlet valve if the inlet valve is at the deflation position. The deflation operation of the inflation device is simple due to the configuration of the push arm.

Abstract: An automatic inflation device includes a valve body, a miniature motor and a centrifugal impeller. The valve body is provided with an air inlet and an inflation inlet, a check valve that is unidirectionally opened outwards the valve body is provided at the inflation inlet, a wind chamber and a wind guide path connected with the wind chamber are configured in the valve body, the miniature motor and the centrifugal impeller are installed in the wind chamber, the centrifugal impeller is actuated by the miniature motor, the wind chamber is communicated with the inflation inlet via the wind guide path, and the air inlet is communicated with a wind inlet of the wind chamber. The structure of the device is compact and reduced, which is applicable to directly install into inflation products. The device can inflate automatically and efficiently, and the structure is simplified and easy to actualize.
