Embodiment Construction
[0017] The structure of the present invention is not very complicated, and its manufacturing difficulty is not high, and its key lies in: on the basis of the structure of the conventional and common existing air pump 4, a metal sealed casing 2 surrounding the former in a three-dimensional form and supporting technologies are added Measures, can realize the leakage of gas during the operation of the present invention to different degrees, and even finally realize the possibility of preventing gas molecules from leaking from the present invention.
[0018] The main body of the structure of the first embodiment of the present invention is shown in the accompanying drawings:
[0019] The air pump 4 and the metal sealed casing 2 that surrounds the air pump 4 in a three-dimensional form are used as an integral structure, and the air intake pipe 6 has a cut-off part of the slit width S in the inner cavity of the casing 2 . .
[0020] A truncated slit width S is set in the straight l...
