When a piston rod is moved upwards and downwards by a user, gas can only flow in or out of the pump body through the corresponding channels when the gas flows in or out of the pump body by means of the design that two one-way valves which are arranged in the pumping device and the gas inlet device are opposite in direction, so that the two-way pump simultaneously has the dual functions of pumping and inflating, and can be simply used according to the use needs.
Description
Technical field
The utility model relates to a kind of two-way inflator, and it refers to a kind of two-way inflator of bleeding and inflating function that has concurrently.
Background technique
Often need bleed or inflate article in the daily life, generally speaking, the article that need use the action of bleeding have package bag of clothing, pillow or cotton-wadded quilt or the like, with packages sealed article such as clothing are isolated extraneous dirty and dust; And often need use inflate tire, balloon or the like arranged, bicycle tyre even may need the action of inflating simultaneously and bleeding especially.Yet when common people need bleed or inflate, pump and the pump bowl that must prepare two kinds of difference in functionalitys usually were required to deal with life, use considerably inconvenient.
The model utility content
Because the instrument of inflating and bleeding of aforementioned prior art is in use is upward inconvenient and than inefficiency, the utility model is developed a kind of two-way inflator, to solve prior art problems.
For reaching above-mentioned creation purpose, the technological means that the utility model adopted is a kind of two-way inflator of design, comprising:
One carrying handle;
One cylindrical shell, one end are provided with a cover piece and cover piece is provided with a through hole, and the other end then is provided with two passages, and this through hole and two passages communicate with inner barrel;
One piston rod, it is located in the cylindrical shell; Through hole and carrying handle that one end of piston rod runs through this cover piece join;
One piston, the other end that it is positioned at inner barrel and is located at piston rod, and the piston periphery is provided with a gas-tight ring; Sealingly the recline cylinder inboard wall face of inflator of this gas-tight ring;
One air extractor, it is located in the wherein passage of cylindrical shell; This air extractor includes an one-way valve; This one-way valve has a gas flow;
One air-inflating device, it is located in another passage of inflator; This air-inflating device includes an one-way valve; This one-way valve has a gas flow, and this gas flow is opposite with the gas flow of the one-way valve of air extractor.
Based on said structure, when gas is desired to enter in the cylindrical shell, the valve block of the one-way valve of air extractor will be subjected to the gas compressing and move up, and be posted by the blocked part of vent cap; Gas then flows into from gas-entered passageway, and the gap that flows to the described blocked part of vent cap flows into cylindrical shell again; Simultaneously, the valve block of the one-way valve of air-inflating device is subjected to the gas compressing and after moving up, just reclines and closing valve mutually with valve.When gas oppressed and when desiring outwards to flow out, the valve block of air extractor will be subjected to the gas compressing and move down and closing valve, the valve block of air-inflating device then moves down and reclines mutually with the blocked part of vent cap, gas flows to the gap of the described blocked part of vent cap thus, then again outside vent cap flows out outlet passageway; That is under the motion of piston rod, by designing two one-way valves of opposite gas flow, and make gas in a certain direction turnover cylindrical shell specific passage of only can flowing through.Therefore, the utility model has the dual functions of bleeding and inflating concurrently, and the suitable easy operating of the utility model, has its practicability and convenience really.
