Summary of the invention
the object of this invention is to provide a kind of simple in structure, easy to operate and portable portable tire pump.
for achieving the above object, the technical solution used in the present invention is: a kind of portable tire pump, described pump comprises the cylindrical shell with air-flow path, described cylindrical shell is provided with the first one-way valve that described air-flow path is separated into the first air cavity and the second air cavity, the second one-way valve, outside air arranges to described the first air cavity unilaterally connected by described the first one-way valve, described the first air cavity arranges to described the second air cavity unilaterally connected by described the second one-way valve, on described cylindrical shell, be also provided with and can make outside air enter the air compressing mechanism in described the first air cavity by described the first one-way valve, described air compressing mechanism comprises is located at the piston cavity being connected with described the first air cavity on described cylindrical shell, be located at movably the piston in described piston cavity, for the spring of described piston along movement direction elastic-restoring force is provided, described air compressing mechanism also comprises for driving described piston at the mobile operation piece of described piston cavity, one end of described operation piece be connected to rotationally on described cylindrical shell and described operation piece by being pressed on described piston, on described cylindrical shell, be also provided with the outlet pipe for being connected with described the second air cavity.
preferably, on described cylindrical shell, be also provided with the relief valve for limiting described the second air cavity internal pressure.
preferably, the L-shaped setting of described cylindrical shell, described cylindrical shell has vertical portion and horizontal part, and described piston is located on described vertical portion, and one end of described operation piece is connected on described horizontal part rotationally, and described operation piece is pressed on described piston.
as a kind of concrete mode of execution, described operation piece is operating handle.
due to the utilization of technique scheme, the present invention compared with prior art has following advantages: portable tire pump of the present invention, can drive air compressing mechanism by pressing operation part, and then make to enter the second air cavity through the first air cavity after outside air compression, be then filled with in device to be inflated by outlet pipe.This inflator structure is simple, and its volume is little, is easy to carry and uses.
Brief description of the drawings
