Abstract
The invention provides a simple type air pump structure capable of avoiding leaking gas molecules in an operation process, which is mainly characterized in that: 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; and on the basis of the structure, a structure treatment of seam splicing and pipe connection is solved through a welding process. The problem of stopping leakage is considered by completely avoiding the magnitude degree of the 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. The structure disclosed by the invention is most suitable for preparing an air pump type with a lower gas flow speed.

At present, the various air pumps that size specification is different with model are the quite extensive and ripe a kind of power equipments of purposes, and its deficiency is: the axle envelope place that during operation mainly is it is the most easily to its gas inside of external leakage.If the gas that leaks is cheap air, more also " the not impairment of the spleen ", if, leakage be expensive gas or hypertoxic gas, just shoulded be regarded as a different matter.---reduce the above-mentioned leakage problem of air pump from structure, be the big problem that people constantly study and manage to solve as far as possible always.
Summary of the invention
The present invention's purpose:
Exactly in order to realize the structural type of air pump device preventing leakage through the technical innovation behave.
In order to realize the object of the invention, intend the technology below adopting:
Have: the common air pump that has its envelope place gas leakage at least that drives through its rotating shaft by dragging motor of conventional structure form; It is characterized in that it comprises:
Above-mentioned by this air pump that dragging motor dragged, and surround the metallic seal shell that this former two constituted by the stereochemical structure form;
Have: the common air pump that has its envelope place gas leakage at least that drives through its rotating shaft by dragging motor of conventional structure form;
It is characterized in that it comprises:
Above-mentioned by this air pump that dragging motor dragged, and surround the metallic seal shell that this former two constituted by the stereochemical structure form;
Be provided with on described this shell through outlet pipe and connect the formed external exhaust port of this air pump relief opening;
Also be provided with on described this shell through suction tude and connect the formed external intake interface of this air pump intakeport;

The present invention and existing technology characteristics relatively:
Because the present invention has passed through on existing conventional and common air pump structural type basis, increased this air pump implemented the three-dimensional metal shell that surrounds character, this just the gas leakage when structurally definitely preventing air pump to move created condition.---its highest structural type can reach the degree that absolute prevention gas molecule leaks.
Description of drawings
Illustrated an embodiment who proposes as structural principle of the present invention.
1: dragging motor; 2: the metallic seal shell; 3: rotating shaft; 4: common air pump (for example: leaf type commonly used); 5: outlet pipe; 6: suction tude; 7: the suction port of common air pump.
Embodiment
Structure of the present invention is not very complicated; Its manufacture difficulty compared with prior art we can say just the same with relevant various technical requirementss; Its key is: on the architecture basics of conventional and common existing air pump 4; Increased by one and surrounded the former metallic seal shell 2 and supporting technological behave with three-dimensional form, can be when realizing in varying degrees preventing the present invention to move the leakage of gas, even finally can also realize the possibility of preventing gas molecule from the present invention, to leak.
First leakproof improvement project of the present invention is seen the principal claim (claim 1) of claim of the present invention:
Surround the overall structure form of the metallic seal housing 2 of air pump 4 with three-dimensional form by air pump 4 and adapted.
Mechanism of the present invention is very simple:
From the gas of air pump 4 internal leakages, will be closed within it in the middle of the chamber by metallic seal housing 2, with a large amount of gases of from suction tude 6, coming in, in the intakeport 7 inspiration bodies of air pump 4, again through discharging behind air pump 4 pressure-raisings.---the gas that leaks in metallic seal housing 2 chambeies is recovered the overall process that re-uses.
As everyone knows; It is not all right that bicycle and automobile a period of time do not inflate; This has just explained a problem fully: the seal degree such as the nonmetal sealing material of one type on rubber is not high; At least can not stop air molecule from the penetrating of this nonmetal sealing material, the speed that just penetrates is slow.If above-mentioned metallic seal housing 2 is to utilize the nonmetal sealing material such as one type on rubber to seal in its piece position with the way that the pipe vicinal that contacts with it is put employing; Or let the pressing piece between the metal covering of extremely bright and clean (bright and clean more also is that roughness is arranged) handle (dismountable), can realize anything but that all stopping gas molecule therefrom penetrates.
Leakage problem possibly be indifferent for the air of cheapness, yet, just not insignificant for some valuable gas leakages or supervirulent gas leakage, although the speed of its leakage is very slow.
So far it seems that first leakproof improvement project of the invention described above is merely able to play the degree of relative leak-stopping
Second leakproof improvement project of the present invention (reaching the degree that stops leakage from molecular level); Be on the basis of above-mentioned first leakproof improvement project; Increase the content of claim 2 again, promptly realized the absolute sealing of highest level among the present invention, its technological behave is:
It all is to realize through welding procedure that the piece (slit) that lets metallic seal shell 2 relate to is put with the pipe vicinal.
---obviously; Although getting into, rotating shaft 3 is easy to leak air pump 4 gas inside when the interior axle envelope of air pump 4 bodies is in air pump 4 operations; But; The gas of this leakage can be enclosed in its cavity by this housing 2, and in this inner chamber enclosed construction, does not have the chance that lets the gas of this leakage might continue to get into airspace.Because gas molecule can't penetrate the three-dimensional leak-stopping defence line that is formed by metallic molecule.
Because the intakeport 7 of air pump 4 is to be open in fully in the Seal cage of metallic seal shell 2 among the present invention; When high velocity air got in the chamber of these shells 2 from suction tude 6, the air-flow section can enlarge suddenly significantly, and its gas flow rate will subtract greatly suddenly; And when this air-flow gets into the suction port 7 of air pump 4; Because the bore of the suction port 7 of air pump 4 dwindles suddenly again, its gas flow rate can increase severely suddenly again, and this process will inevitably produce very big " throttling " loss; And solve the effective technology means that problem is lost in this " throttling ", be exactly the gas flow rate that reduces significantly through air pump 4.For this reason, structure of the present invention is suitable for processing the air pump type of low gas flow rate most.
So far; The key concepts that more should be appreciated that structural design of the present invention is: allow this air pump 4 inevitably from its internal leakage gas; But, do not allow structurally might to let this gas of leaking continue again to get into airspace and cause waste or harmful effect (gas that refers to costliness or severe toxicity).
What the present invention relates to is the most general and the simplest water pump industrial products belong to least flimsy industrial products in the using process, has created condition for realizing its non-removable welding procedure; Its suitable category more should be conspicuous; Therefore, we can say that by the most high-grade formed product of anti-leak means (welding), its practicability is the strongest according to the present invention, and, also have very high " cost performance ".
