Description

A kind of low noise oxygenerator exhaust structure

Technical field

The present invention relates to oxygenerator technical field more particularly to a kind of low noise oxygenerator exhaust structures.

Background technique

Medical oxygen generator, can partner treatment cardiovascular and cerebrovascular, respiratory system, chronic obstructive pneumonia etc. by supplying oxygen to patient The rehabilitation of disease and anoxic illness can improve the oxygen supply situation of body by oxygen uptake, achieve the purpose that tonic health care.Its Suitable for the middle-aged and the old, constitution chump, pregnant women, college admission examination etc. there are the crowd of different degrees of physiological anoxic, Fatigue can be eliminated after weight physical strength or mental consumption, restore physical function.In use, the air after being desorbed in oxygenerator It is discharged by exhaust and muffler tube, existing muffler effect when solving the problems, such as noise reduction is not satisfactory, so as to cause indoor confession Sound is big at work for oxygen equipment, causes noise pollution, and very big influence is caused to the usage experience of user.

Summary of the invention

The present invention provides a kind of low noise oxygenerator exhaust structures, can reduce the noise in use process.

In order to reach the purpose, the present invention adopts the following technical scheme:

A kind of low noise oxygenerator exhaust structure, it is characterised in that: air inlet and outlet including shell and the shell both ends Mouthful, it is equipped with inner casing on the inside of the shell, the inner casing is equipped with through-hole, and the through-hole is equipped with tabs, and the tabs is to described Side turns down between inner casing and the shell, and flexible noise reduction layer is covered on the tabs, and the elasticity noise reduction layer is led to described Hole contact aside is arranged, and is equipped with circulation stomata close to described air inlet one end on the inner casing, and the circulation stomata is equipped with extra large Continuous block.

As a preference, the tabs is circumferentially uniformly arranged along the inner casing.

As a preference, the tabs is semicircular structure.

As a preference, the air inlet side is equipped with dispersion plate, the dispersion plate is close to described air inlet one end Tapered surface is equipped with air passing hole close to inner casing inner surface region on the tapered surface.

As a preference, the shell inner surface is equipped with noise reduction bed course, the noise reduction layer is made of wave cotton material, The wavy bulge of the wave cotton is arranged towards the inner casing.

As a preference, the gas outlet is oppositely arranged with the air inlet, it is equipped with net at the gas outlet and knits noise reduction Plate.

To sum up, compared with the prior art, the advantages of the present invention are as follows: tabs can effectively be inhaled with elastic noise reduction layer thereon The gas for receiving discharge, when gas displacement increases pressure greatly, gas extrusion elasticity noise reduction layer simultaneously enters between inside and outside shell, and Enter inner casing by recycling stomata, increases the flow path of gas, play the effect of noise reduction.

Detailed description of the invention

Fig. 1 is structural schematic diagram of the invention.

Label in figure is as follows:

1. shell, 11. air inlets, 12. gas outlets, 13. noise reduction bed courses, 14. nets knit acoustical panel, 2. inner casings, 21. through-holes, 22. foldings Piece, 23. elastic noise reduction layers, 24. circulation stomatas, 25. sponge blocks, 3. dispersion plates, 31. air passing holes.

Specific embodiment

The invention will be further described for middle embodiment with reference to the accompanying drawing.

A kind of low noise oxygenerator exhaust structure as shown in Figure 1,11 He of air inlet including 1 both ends of shell 1 and shell Gas outlet 12, is equipped with inner casing 2 on the inside of shell 1, and inner casing 2 is equipped with through-hole 21, and through-hole 21 is equipped with tabs 22, and tabs 22 is to inner casing Side turns down between 2 and shell 1, covers flexible noise reduction layer 23 on tabs 22.Elastic noise reduction layer 23 is chosen as sponge material system At being wrapped in the outside of tabs 22, can be glued on tabs 22, elastic noise reduction layer 2313 is arranged with 21 contact aside of through-hole, interior It is equipped with circulation stomata 24 close to 11 one end of air inlet on shell 2, circulation stomata 24 is equipped with sponge block 25.It is rolled on 2 inner sidewall of inner casing Region between piece 22 can paste setting spongy layer.

Tabs 22 forms concaveconvex structure on 2 inner sidewall of inner casing with elastic noise reduction layer 23 thereon, can effectively absorb row Gas out, when gas displacement increases pressure greatly, gas extrusion elasticity noise reduction layer 23 simultaneously enters between inside and outside shell 1, and passes through It crosses circulation stomata 24 and enters inner casing 2, increase the flow path of gas, play the effect of noise reduction.Tabs 22 is circumferential uniformly along inner casing 2 Setting, tabs 22 are semicircular structure.

The diameter of air inlet 11 is small compared with 2 diameter of inner casing, and 11 side of air inlet is equipped with dispersion plate 3, and dispersion plate 3 is close to air inlet 11 one end are tapered surface, are equipped with close to 2 inner surface region of inner casing equipped with air passing hole 31 on tapered surface, gas passes through air passing hole 31 And 2 adjacent sidewalls of inner casing are distributed to, it is convenient for noise reduction after passing through dispersion plate 3.1 inner surface of shell is equipped with noise reduction bed course 13, noise reduction Bed course 13 is made of wave cotton material, and the wavy bulge of wave cotton is arranged towards inner casing 2.It further include opposite with air inlet 11 Gas outlet 12 is equipped with net at gas outlet 12 and knits acoustical panel 14.

Described above is only explanation of the invention, so that those of ordinary skill in the art's can completely implements we Case, but be not the limitation to invention, those skilled in the art can according to need after reading this specification to this implementation Example makes the modification of not creative contribution, these are all without creative modification, but as long as in the claim of invention All by the protection of Patent Law in range.
