Abstract

The invention discloses a large-air-volume inflator. The large-air-volume inflator comprises an outer pipe, a middle pipe and an inner pipe. The front end of the outer pipe is fixedly connected with a front cover in a sealed manner. The front end of the inner pipe is fixedly connected with the front cover in a sealed manner. An air outlet assembly is arranged on the front cover. The rear end of the middle pipe extends out of the rear end of the outer pipe and is fixedly connected with a rear cover in a sealed manner. A first one-way seal piston assembly is fixedly arranged at the front end of the middle pipe. A second one-way seal piston assembly is fixedly arranged at the lower end of the inner pipe. The large-air-volume inflator is characterized in that a first ventilation opening is formed in the side wall of the front end of the middle pipe; a second ventilation opening is formed in the side wall of the front end of the inner pipe; a first one-way air inlet valve which can only introduce air into the inner pipe is arranged in the second one-way seal piston assembly; and a second one-way air inlet valve which can only introduce air into the inner pipe or the air outlet assembly is arranged at the position of the second ventilation opening. The large-air-volume inflator has the beneficial effects that compared with a traditional single-cylinder inflator, the single-time inflation volume of the large-air-volume inflator is large, the number of tire inflation times can be halved, the tire inflation time is greatly saved, the inflation efficiency is improved, and meanwhile the effect of saving labor is achieved.

Description

technical field [0001] The invention relates to an air pump, in particular to a large volume air pump. Background technique [0002] The air pump is a tool used in our daily life to inflate tires such as bicycles and baby carriages. At present, the pumps on the market include single-cylinder pumps, double-cylinder pumps, and internal booster pumps. When in use, the pumping time is relatively long, and it is more laborious to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a large-volume air pump with large air output and labor-saving use. [0004] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a large-capacity pump, including an outer tube, a middle tube, and an inner tube that are socketed in sequence, the front end of the outer tube and the front end of the inner tube They are respectively sealed and fixedly connected with the front cover, the...
