Abstract
The present invention relates to a vacuum pump for a sealed container,
A cylindrical body having an open lower end portion having a cylindrical body 10 formed at an inner central upper end portion thereof, a lower movable body 20 coupled to a lower end of the cylindrical space in the cylindrical body 10 in a relative movable state, and the lower movable element ( 20 that penetrates the center portion and has an upper end portion connected to the cylinder body 10 and penetrates an upper end portion of the cylinder body 10 and extends vertically downward to contact the lower movable body 20. Press power transmission 40, a lower support 50 coupled to the lower end of the intake pipe 30 and the lower end of the cylinder 10, and a spring located between the lower movable body 20 and the lower support 50 ( By including 60),
Since the internal structure is simple and reasonable, it is possible to obtain a vacuum pump for a hermetically sealed container in which a high degree of vacuum can be secured quickly with little force.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum pump for a closed container, and more particularly, to a vacuum pump of a very preferred form capable of ensuring a high degree of vacuum while having a simple internal structure.
In order to prevent corruption of foods, it is common to put them in a sealed container and put them in a refrigerator. Recently, the inside of the sealed container is first vacuumed with a vacuum pump before being put into the refrigerator.
Even in the case of storing fruits or vegetables in an airtight container in a refrigerator, it is common to confirm their decay after a considerable period of time, and the process of decay is due to the presence of air inside the airtight container and the propagation of microorganisms. Vacuum state storage such as this is said to have a significant meaning in terms of suppressing corruption.
In view of this, in recent years, several types of vacuum pumps for hermetic containers have been developed and marketed.
However, due to structural irrationality such as the intake from the sealed container to the vacuum pump and the evacuation operation from the vacuum pump to the atmosphere at the same time, it is difficult to pump the pumping operation for the vacuumization, and also includes the exhaust passage structure as a whole. There is a complicated structure.
Furthermore, since it is a kind of unusual structure that uses a conventional airtight O-ring as a valve, it is inevitable that air is mixed on the exhaust passage and high vacuum is maintained despite several pumpings. It is inevitable to point out the intrinsic problem that is actually difficult.
SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and an object thereof is to provide a vacuum pump for a closed container of a preferred form, which is capable of ensuring a high degree of vacuum quickly with low force due to a simple and reasonable internal structure.
The object of the present invention as described above is achieved by adopting an air releasing structure in which the air inside the vacuum container to be evacuated is sucked into the cylindrical space having the through hole and the valve plate leading to the atmosphere, and at the same time, the air is discharged directly to the atmosphere.
According to the present invention, it is possible to obtain a vacuum pump for an airtight container of a very preferable form, in which the overall structure including the air discharge structure from the vacuum pump to the atmosphere is simple as well as high vacuum can be secured and work efficiency is high.
EMBODIMENT OF THE INVENTION Hereinafter, the vacuum pump for sealed containers of the Example of this invention is demonstrated in detail based on an accompanying drawing.
