Due to the air generating structure of the air pump, the condition that the air pump can be used as an inflation pump and can also be used as a vacuum pump for air exhaust can be realized.
Description
Technical field
The utility model relates to air pump technical field, is specifically related to a kind of air pump gas making structure.
Background technique
Traditional gas-filled pump can not be made vacuum pump and use, and vacuum pump can not be made gas-filled pump and use.Because the air pump of two kinds of different purposes all adopts the import/exhaust valve mechanism of traditional upper entering and lower leaving or bottom in and top out, by an air intake valve or drain tap, be arranged on the piston in cylinder, gas-filled pump at the air inlet of the bottom of piston, vacuum pump in the exhaust of the bottom of piston, this structure only realizes a kind of function thus, inflation or bleed, must cause that gas-filled pump can not vacuumize, vacuum pump can not make gas-filled pump and use.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of air pump gas making structure, this air pump gas making structure can realize same air pump not only as gas-filled pump use, but also as the vacuum pump use of bleeding.
For addressing the above problem, the utility model provides a kind of air pump gas making structure, this air pump gas making structure comprises cylinder head, dividing plate, cylinder, exhaust joint, air input joint, drain tap, air intake valve, connecting rod, bent axle, piston, piston ring, the internal surface of described cylinder head is provided with uncovered downward the first air storing cavity and the second air storing cavity spaced apart from each other inwards, described dividing plate is connected between cylinder head and cylinder, and the first air storing cavity and the second air storing cavity are divided into seal space, described exhaust joint is arranged on cylinder head and with the first air storing cavity and is communicated with, described air input joint is arranged in cylinder head and with the second air storing cavity and is communicated with, described drain tap be arranged on dividing plate and orientation for to lead to the first air storing cavity by cylinder, described air intake valve be arranged on dividing plate and orientation for to lead to cylinder by the second air storing cavity, described piston is arranged in cylinder, described piston ring tightly fits between cylinder inner wall and piston, described piston is connected with connecting rod, described connecting rod is connected with bent axle.Same in correlation between cylinder, piston, connecting rod, bent axle and prior art, here just no longer describe in detail.
The eccentric weight of described bent axle and connecting rod weight are symmetrical, at the middle maintenance assembled machine balance that runs up.Bent axle drivening rod moves up and down piston in cylinder, and when piston makes progress, drain tap is opened, air intake valve closes, pressurized air is sent outside machine, when piston is downward, air intake valve is opened, drain tap is closed, by air intake, reach the object of axle vacuum.
Adopt after above structure, the utility model compared with prior art, have the following advantages: the utility model air pump gas making structure in use, only need be connected on airduct and on exhaust joint, can be used as gas-filled pump, be connected on air input joint and can be used as vacuum pump, uses very convenient.So this air pump gas making structure can realize same air pump not only as gas-filled pump use, but also as the vacuum pump use of bleeding.
As preferably, described piston ring adopts self lubricating material to make.Piston ring adopts self lubricating material, producing self-lubricating function in friction up and down at a high speed, without oily, makes source of the gas without oil pollution.
Accompanying drawing explanation
Shown in Fig. 1 is the structural representation of the utility model air pump gas making structure.
Wherein: 1, cylinder head; 2, dividing plate; 3, cylinder; 4, connecting rod; 5, bent axle; 6, piston; 7, piston ring; 11, exhaust joint; 12, air input joint; 13, drain tap; 14, air intake valve; 15, the first air storing cavity; 16, the second air storing cavity.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
