The inner cylinder body (7) is composed of a double-layer cylinder body which is connected into integration by the straight rib; an air storage sandwich layer(8) is arranged between the double-layer cylinder body; the air storage sandwich layer(8) is connected with an outer one-way valve (4) arranged on the outer piston; the outer one-way valve (4) is communicated with an upper chamber (2); the air storage sandwich layer(8) is communicated with an airway (14) on the connecting seat(13). After adopting the structure, the upper chamber (2)and a lower chamber(11) are respectively inflated through the outer one-way valve (4) and the one-way valve (12), and are combined and formed integration; the produced gas can be stored in the gas storage sandwich layer (8); the gas storage sandwich layer (8) is functioned as high pressure gas bag, and has the characteristic of double high pressure inflator; the gas producing device using high pressure inflator has the advantages of simple and reasonable structure, light weight, large gas production, double inflation and such.

Description

The gas cylinder aerogenesis apparatus

Technical field

The utility model relates to a kind of inflator, and particularly a kind of hand is played the improvement with the Pedal inflator aerogenesis apparatus.

Background technique

For the ease of bicycle, motorcycle, the tyre inflation of vehicles such as tricycle, Patent Office of the People's Republic of China discloses a kind of novel pump on April 22nd, 1998, the patent No. is 96240985.5, its structure is that the inner barrel that an end has outer piston is set in a big slightly outer cylinder body, a piston is arranged in the inner barrel, air-guide standpipe passes the intercommunicating pore on the outer piston, one end is fixed on the upper base of outer cylinder body, the other end is connected with intercommunicating pore on the inner carrier, air-guide standpipe has pore near an end of upper base, the upper base of outer cylinder body is provided with one-way valve, and the other end of inner barrel sets out valve.When being characterized in utilizing the pump of this structure, inside and outside cylindrical shell is inflated through outlet nozzle after lower chambers is converged by inside and outside piston while aerogenesis, and gas production is big, efficient is high; Its deficiency is: the one, and the pressurized gas of the generation of last inner chamber enters lower inner cavity by air-guide standpipe, increases the resistance to motion of inner carrier; The 3rd, as long as there is a piston to leak air, just can't use; The 3rd, there is not air-storage chamber, feel is heavier relatively.

Summary of the invention

For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provide a kind of rational in infrastructure, feel is light, gas production is big, the gas cylinder aerogenesis apparatus of dual inflation.The technological scheme that its technical problem that solves the utility model adopts comprises outer cylinder body, inner barrel, piston rod, outer piston, inner carrier, connecting base, one-way valve, the end of piston rod and coaxial setting of outer cylinder body and fixed outer cylinder body, inner barrel is fixed on the connecting base, outer piston is fixed on the inner barrel top, outer cylinder body is socketed on the inner barrel, piston rod passes the outer piston center hole and fixes with the inner carrier that is arranged on the inner barrel, one-way valve is arranged on the connecting base, one end of one-way valve communicates with lower chambers, the other end links to each other with air flue on the connecting base, described inner barrel is made of the double-layer barrel that straight muscle is connected as a single entity, be provided with the air storage interlayer between the double-layer barrel, the air storage interlayer links to each other with outer one-way valve on being arranged on outer piston, and outer one-way valve communicates with upper chamber, and the air storage interlayer is communicated with air flue on the connecting base.

In order to prevent upper chamber's gas leakage, described outer piston is provided with the seal ring that cooperates with piston rod, guarantees motion sealing between outer piston and the piston rod.

For the ease of interior pipe air inlet, the straight muscle of described inner barrel is provided with inlet hole.

Cooperate for the ease of inside and outside cylindrical shell, the bottom of described outer cylinder body is fixed with bottom.

After adopting said structure, upper chamber and lower chambers are inflated respectively by outer one-way valve and one-way valve, unite two into one, the gas that is produced can be stored in the air storage interlayer of double-layer barrel, the air storage interlayer plays the effect of high pressure gas bag, characteristic with dual gas cylinder, one of them blow-by of piston can not have influence on another pistons work; Have simple and reasonable, advantages such as feel is light, gas production is big, dual inflation.
