Description
Technical field
The utility model belongs to and charges and discharge gas product class, specifically is a kind of two-way air pump that charges and discharge.
Background technique
Common double on the market all needs four valve sheets to charging and discharging air pump, and the air-exchanging structure more complicated is inflated and gone wrong easily in the process, and production and assembly are loaded down with trivial details, gives to produce and use and bring inconvenience.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, provides that a kind of component are few, air-exchanging structure simple, the two-way air pump that charges and discharge of reliable performance.
The technical solution of the utility model is as follows:
A kind of two-way air pump that charges and discharge comprises cylindrical shell, is provided with piston in cylindrical shell, is provided with loam cake above cylindrical shell, and loam cake central authorities wear a core, in the upper end of this core one handle are arranged, and the lower end links to each other with piston in the cylindrical shell, and sealing cover is arranged at the cylindrical shell bottom, it is characterized in that:
Piston is made up of piston ring, bundle circle, diaphragm seal, two one-way cock sheets, piston ring has two openings, internal piston is provided with a suction chamber and a discharge chamber, upper and lower at suction chamber is provided with two one-way cock sheets, the opening of two one-way cock sheets has diaphragm seal, can hold air and enter cylinder lumen by suction chamber, reaches unidirectional air inlet effect, the outside of discharge chamber is provided with an opening, by realizing the two-way function that push-and-pull is all given vent to anger with relatively moving of bundle circle;
Axle core hollow, have a dividing plate, dividing plate axially is being separated into two chambers, one is gas-entered passageway, one is outlet passageway, the upper and lower end of gas-entered passageway and outlet passageway is formed with breach respectively, and the breach of upper end communicates with handbar suction port and air outlet respectively, and the breach of lower end communicates with the suction chamber and the discharge chamber of piston respectively; Axle core upper and lower end is connected with handle, piston thread respectively, is fitted by cushion respectively in the joint.
The utility model is because the quill shaft core is divided into two passages, makes that to charge and discharge the air pump structure simpler, Component still less, maintenance is more convenient, and allows the chance of gas leakage reduce, and improves whole quality; Ventilation effect is good, and performance is more stable, can effectively improve production and assembly efficient, reduces raw-material use and reduces cost; And operation is easier, uses more reliably, and the life-span is longer.

Embodiment
Shown in Fig. 1,2,3,4, a kind of two-way air pump that charges and discharge, it has a cylindrical shell 5, be provided with piston in cylindrical shell 5, be provided with loam cake 4 above cylindrical shell, loam cake central authorities wear a core 6, one handle 23 is arranged in the upper end of this core 6, the lower end links to each other with piston in the cylindrical shell 5, and sealing cover 16 is arranged at the cylindrical shell bottom, it is characterized in that:
Piston is made up of piston ring 11, bundle circle 12, diaphragm seal 18, last one-way cock sheet 20 and following unidirectional valve sheet 17, piston ring 11 has two openings, internal piston is provided with a suction chamber 19 and a discharge chamber 13, be provided with one-way cock sheet 20, following unidirectional valve sheet 17 at the upper and lower of suction chamber, sealed 18 of the opening of last one-way cock sheet 20 and following unidirectional valve sheet 17 blocked, can hold air and enter cylinder lumen by suction chamber, the outside of discharge chamber is provided with an opening, by realizing the two-way function that push-and-pull is all given vent to anger with relatively moving of bundle circle 12;
The axle core 6 of hollow axially is being separated into two chambers by dividing plate 8, one is gas-entered passageway 9, one is outlet passageway 7, the upper and lower end of gas-entered passageway 9 and outlet passageway 7 is formed with breach respectively, the breach of upper end communicates with handbar suction port 24 and air outlet 2 respectively, and the breach of lower end communicates with the suction chamber 19 and the discharge chamber 13 of piston respectively; Axle core upper and lower end is connected with handle 23, piston thread respectively, and by last cushion 1, cushion 14 applyings down, there are sealing cover 22 and diaphragm seal 21 in axle core and loam cake 4 joints respectively in the joint.
As shown in Figure 2, during pull-up handle 23, affect a core 6, piston ring 11 to mention simultaneously, gas flows into the suction chamber 19 of piston by the gas-entered passageway 9 of axle core from handle suction port 24, owing to the single effect of unidirectional valve sheet 17 down, gas enters cylindrical shell lower seal space 15; The gas in cylindrical shell top seal space 10 is the discharge chamber 13 of stepping down and entering piston of transmitted beam circle 12 then, flows through the outlet passageway 7 of a core, flows out from the air outlet 2 of handle at last.
As shown in Figure 3, when pressing lower handle 23, pushing shaft core 6, piston ring 11 move down simultaneously, and gas flows into the suction chamber 19 of piston by the gas-entered passageway 9 of axle core from handle suction port 24, because the single effect of last one-way cock sheet 20, gas enters cylindrical shell top seal space 10; The gas in cylindrical shell lower seal space 15 is the discharge chamber 13 of stepping down and entering piston of transmitted beam circle 12 then, passes the outlet passageway 7 of a core, flows out from the air outlet 2 of handle at last, realizes charging and discharging the charging-discharging function of gas product when going out air inlet voluntarily.
The utility model is two-way to charge and discharge on the piston of air pump only need have two one-way cock sheets to control the unidirectional of air inlet, give vent to anger unidirectional then be relatively moving to step down and realize by bundle circle 12 and piston ring 11.
Two little perpendicular muscle are arranged on the utility model piston, and when combining with the axle core, the thread by the tapping of axle core matches makes in conjunction with closely, reduces gas leakage; This handle is an on-slip type handle, is provided with outside thread 3 on the handle air inlet/outlet, is convenient to the wave pipe and takes out, locks and difficult drop-off.
