Abstract

The present invention relates to an air intake/discharge structure for a vacuum pump and a vacuum pump using the same. The structure comprises a T-shaped ventilation body (10) including a central vertical pipe (a) and a circular horizontal plate (b), and vertical cylinders (20, 20') of which the top is open. The body (10) includes an air intake hole (h2) and an air discharge hole (h3) which are respectively connected to a vent (h1) inside the central vertical pipe (a). In the vertical cylinders (20, 20'), the inner circumference and bottom central vent thereof are respectively coupled with the outer circumference of the circular horizontal plate (b) and the outer circumference of the central vertical pipe (a), and permitted to move. The intake/discharge structure draws air into a sealed container, which is about to form a vacuum, into the cylindrical space formed between the circular horizontal plate (b) and the bottoms of vertical cylinders (20, 20'), then discharges the air. According to the development of the intake/discharge structure and a vacuum pump using the same with the above features, the entire structure including an air discharge structure for expelling air from the vacuum pump is simplified and an excellent vacuum is secured. In addition, a small vacuum pump with high work efficiency is provided.
