Description
Technical field
the present invention relates to a kind of pump, particularly a kind of portable tire pump.
Background technique
pump, is also referred to as air pump, in order to inject or to supplement various tire and some ball required air.At present, the most of pumps on market, advancing pressurized air nothing more than arranging piston in a cylindrical shell, adopting manpower pull, being filled with air by valve in tire or ball.This type of pump, because of with longer cylindrical shell, is inconvenient to carry.
Summary of the invention
the object of this invention is to provide simple, the easy to operate and portable portable tire pump of a kind of structure.
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 described air-flow path being separated into the first air cavity and the second air cavity, second one-way valve, outside air is arranged to described first air cavity unilaterally connected by described first one-way valve, described first air cavity is arranged to described second air cavity unilaterally connected by described second one-way valve, described cylindrical shell is also provided with outside air can be made to enter the air compressing mechanism in described first air cavity by described first one-way valve, described air compressing mechanism comprises the piston cavity be located at and described cylindrical shell is connected with described first air cavity, be located at the piston in described piston cavity movably, for providing described piston along the spring of movement direction elastic-restoring force, described air compressing mechanism also comprises the operation piece for driving the movement in described piston cavity of described piston, one end of described operation piece to be connected to rotationally on described cylindrical shell and described operation piece by being pressed on described piston, described cylindrical shell is also provided with the outlet pipe for being connected with described second air cavity.
preferably, described cylindrical shell is also provided with the relief valve for limiting described 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, air compressing mechanism can be driven by pressing operation part, and then enter the second air cavity through the first air cavity after outside air is compressed, 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 use.
Accompanying drawing explanation
accompanying drawing 1 is the structural representation of the portable tire pump of the embodiment of the present invention 1;
accompanying drawing 2 is the structural representation of the portable tire pump of the embodiment of the present invention 2;
wherein: 1, cylindrical shell; 11, the first one-way valve; 12, the first air cavity; 13, the second one-way valve; 14, the second air cavity; 15, relief valve; 2, air compressing mechanism; 21, piston; 22, spring; 23, operating handle.
Embodiment
below in conjunction with accompanying drawing and specific embodiment, technological scheme of the present invention is further elaborated.
embodiment 1
portable tire pump shown in Figure 1, comprise the cylindrical shell 1 with air-flow path, cylindrical shell 1 is provided with the first one-way valve 11, second one-way valve 13 and the relief valve 15 air-flow path being separated into the first air cavity 12 and the second air cavity 14, outside air is arranged to the first air cavity 12 unilaterally connected by the first one-way valve 11, first air cavity 12 is arranged to the second air cavity 14 unilaterally connected by the second one-way valve 13, overflow pressure relief when relief valve 15 exceedes particular value for the second air cavity 14 internal air pressure.
shown in Figure 1, cylindrical shell 1 is also provided with outside air can be made to enter the air compressing mechanism 2 in described first air cavity 12 by described first one-way valve 11, this air compressing mechanism 2 comprises the piston cavity be located at and cylindrical shell 1 is connected with the first air cavity 12, be located at the piston 21 in piston cavity movably, for providing piston 21 along the spring 22 of movement direction elastic-restoring force, this air compressing mechanism 2 also comprises the operation piece 23 for driven plunger 21 movement in piston cavity, one end of this operation piece 23 is connected on described cylindrical shell 1 rotationally, its the other end is by being pressed on the outer end of piston 21.
shown in Figure 1, operation piece in this enforcement is operating handle 23, it is driven to rotate by holding operation handle 23 when inflating, operating handle 23 presses the elastic force that piston 21 makes piston 21 overcome spring 22 and moves in piston cavity, thus the air in the external world is blasted in the first air cavity 12, pressure in first air cavity 12 constantly increases, then the gas in the first air cavity 12 is entered in the second air cavity 14 by the second one-way valve 13.
shown in Figure 1, cylindrical shell 1 being also provided with the outlet pipe for being connected with the second air cavity 14, when inflating, in outlet pipe, plugging valve, namely by valve, the pressurized gas in cylindrical shell 1 being filled with in tire to be inflated or spheroid.
embodiment 2
portable tire pump shown in Figure 2, the difference part of itself and embodiment 1 is mainly the shape of cylindrical shell 1.In the present embodiment, the L-shaped setting of cylindrical shell 1, this cylindrical shell 1 has vertical portion and horizontal part, and piston 21 is located on vertical portion, and one end of operating handle 23 is connected on horizontal part rotationally, and such setting is more attractive in appearance, and convenient operation person grips.
to sum up, portable tire pump of the present invention, wherein can be completed by pressing operation handle 23 and inflate operation, and this inflator structure is simple, easy to use and be easy to carry about with one.
above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
