The invention discloses an integrated combined inflator. The inflator is characterized in that a combined cylinder body is assembled on a base of the inflator, an upper cover is arranged at the upperend of the combined cylinder body, a lower cover is arranged at the lower end of the combined cylinder body, an air storage cylinder, an air outlet cylinder and a piston air cylinder are arranged in the combined cylinder body in parallel, the lower cover is correspondingly provided with an air storage channel, an air outlet channel and an inflating channel, a piston rod is arranged in the piston air cylinder, the upper end of the piston rod penetrates through the upper cover to be connected with a handle, the lower end of the piston rod is connected with a piston, a check valve is arranged inthe inflating channel, and an air outlet pipe is arranged in the air outlet cylinder; and a valve element matched with the base in a rotating mode is arranged on the base, state switching is completedby rotating the valve element, in the inflating state, the piston air cylinder and the air outlet cylinder communicate with each other through the valve element, in the air storage state, the pistonair cylinder and the air storage cylinder communicate with each other through the valve element, and in the high-pressure air outlet state, the air storage cylinder and the air outlet cylinder communicate with each other through the valve element. The inflator has the advantages of being reasonable in structure, low in manufacturing cost, convenient to use, store, and carry and capable of meetingthe air supplement requirements of ordinary tires and vacuum tires.
