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...

Abstract

The invention provides an improved scheme of an air pump structure capable of reducing or avoiding air leakage in an operation process. The typical type is as follows: on the basis of the existing conventional and common air pump structure form, a metal shell (2) for implementing a three-dimensional surrounding property on an air pump (4) is additionally arranged; one part of an air inlet pipe (6), which is located in the middle of an inner cavity of the shell (2), is provided with a cut part with a seam width (S); or on the basis, a sealing structure treatment of seam splicing and pipe connection is solved through a welding process. The improved highest form is that the problem of stopping leakage is considered by completely avoiding the magnitude degree of gas molecules leaked by the structure. The key design idea is realized by that: the air pump (4) is allowed to inevitably leak gas from the inner part; however, the possibly-leaked gas is not structurally allowed to continually enter an atmosphere space. The 'cost performance' of the improved scheme is very high and the use scope is obvious.

Description

technical field [0001] The invention relates to a fully sealed structural form of an air pump device, in particular to a design scheme of an air pump structural 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 structural design technical solutions under the premise of absolutel...
