Embodiment Construction
[0018] The structure of the present invention is not very complicated, and its manufacturing difficulty is not high, and its key lies in: on the structural basis of the conventional and common existing air pump 7 and its driving motor, an increase of a three-dimensional form surrounds the former two metal The airtight isolation shield 5 and related supporting technical measures can realize to various extents to prevent the gas leakage during the operation of the present invention, and even finally realize the possibility of preventing gas molecules from leaking from the present invention.
[0019] The wall thickness of the metal-sealed isolation shield 5 among the present invention is not equal, and the metal-sealed isolation shield 5 part between the motor rotor 2 and the motor stator 1 should adopt as thin as possible a rigid non-magnetic metal material. For example, a stainless steel or brass plate of about 0.2 mm can be used to act; the wall thickness of the metal sealing i...

Provided is an improved scheme capable of reducing or eliminating air leakage in operation for the structure of an aim pump. The typical model of the improved scheme is that on the basis of the structure of a conventional and regular air pump (7), a metal sealing isolation shield (5) is additionally arranged to surround the air pump (7) and the rotor (2)of a driving motor in a stereoscopic manner, and a section of an air inlet pipe (8), which is positioned in the cavity of the metal sealing isolation shield (5), has holes (K) on the tube wall, or on the above basis, the sealing structure of seam splice and pipe connection is realized via the welding technology. The improved solution, to the maximum, enables leakage to be prevented through absolute prevention of the degree of molecules of gas leaked from the structure. The key design notion of the improved solution is to allow gas to be leaked from inside of the air pump (7) inevitably, but not to allow the gas that has been leaked to possibly enter the atmosphere again. The improved structure of the aim pump is high in cost performance and can be obviously applied to the various fields.
Description
technical field [0001] The invention relates to the sealing structure technology of an air pump device, in particular to various improvement scheme technologies of detachable motor stators of the air pump device capable of reducing or eliminating air leakage during operation. Background technique [0002] At present, various air pumps with different sizes, specifications and models are widely used and mature power equipment. Their disadvantage is that the shaft seal is the most likely to leak the gas inside during operation. If the leaked gas is cheap air, it will not hurt the stomach at all. If the leaked gas is expensive or highly toxic gas, it is another matter. ——Reducing the above-mentioned leakage problem of the air pump structurally as much as possible has been a big subject that people have been studying and trying to solve constantly. Contents of the invention [0003] Purpose of the present invention: [0004] It is to achieve different degrees of technical sol...
