Abstract

An inflating device comprises a valve body and a gasbag, the valve body being provided with a gas inlet, a gas outlet and a gas storage chamber; the gas inlet has a gas intake valve device provided therein, and the gas outlet has a gas exhaust valve device provided therein; the gas storage chamber is communicated with the gasbag; and the gas inlet is communicated with the gas outlet through a chamber body of the valve body, and the gas storage chamber is communicated with the chamber body. In the invention, gas can be fed into an inflatable product by continually pressing with hands, without requiring electricity or blowing with mouth. The inflating device of the invention is convenient to operate, clean and sanitary. The inflating device of the invention has a small volume and is thus convenient to carry.
