The invention discloses a double-gas-cylinder inflation device which comprises a double-engine base, an electric
detonator, two pricking needles and two gas cylinders, the double-engine base comprises a base body, an air inlet
pipe, two gas distribution pipes, two high-pressure pipes and an
exhaust pipe, the air inlet
pipe, the two gas distribution pipes, the two high-pressure pipes and the
exhaust pipe are arranged in the base body, and an outlet of the air inlet
pipe is communicated with inlets of the two gas distribution pipes. Outlets of the two gas distribution pipes are respectively communicated with first inlets of the two high-pressure pipes, and outlets of the two high-pressure pipes are both communicated with an inlet of the
exhaust pipe; an outlet of the electric
detonator is communicated with an inlet of the air inlet pipe; the two pricking needles are connected into the two high-pressure pipes in a sliding mode correspondingly. The air inflation device has the beneficial effects that the structural design of the double air cylinders and the double engine seats is adopted, compared with a traditional single-air-cylinder or single-air-source air inflation device, the air inflation device can provide air with larger flow in a short time, the air inflation speed is greatly increased, and the air inflation efficiency is greatly improved.
