Description

A kind of exhaust and muffler tube of medical oxygen generator

Technical field

The present invention relates to medical oxygen generator field, specifically relate to the exhaust and muffler tube of a kind of medical oxygen generator.

Background technology

In the modern life, people are readily formed be seen everywhere close while self live and work environment improving Closing property anaerobic environment, such as air-conditioned room, tight-closed automobile, the public place of ventilation condition difference, work and study simultaneously are nervous Brain worker and the junior-senior high school examination big students preparing for examination of pressure, participate in strenuous exercise after people and live in existing for a long time For the anoxia phenomenon the most in various degree of the people in the serious environment pollution of city.

Medical oxygen generator, by patient's oxygen supply, can partner treatment cardiovascular and cerebrovascular vessel, respiratory system, chronic obstructive pneumonia Etc. disease, and the rehabilitation of anoxia disease, the oxygen supply situation of health can be improved by oxygen uptake, reach to take a tonic or nourishing food to build up one's health the purpose of health care. It is applicable to middle-aged and elderly people, body constitution chump, pregnant women, college admission examination etc. and there is the crowd of physiological anoxia in various degree, also Can weight physical or mental consumption after allaying tiredness, recover physical function.

After gas molecule sifting bed in medical oxygen generator reaches certain saturation degree, empty through the high pressure of air compressor compression Gas enters molecular sieve bed by rinsing desorbing valve, and molecular sieve bed is rinsed desorbing, and the air after desorbing is through exhaust noise silencing Bank of tubes goes out medical oxygen generator.Existing deafener effect when solving the problem of noise reduction is not ideal, thus causes indoor oxygen supply Equipment operationally sound is big, causes noise pollution.

Summary of the invention

The problem existed for prior art, solving the humidification bottle in existing medical oxygen generator needs frequently to change, and makes The problem becoming waste, the invention provides a kind of oxygen humidification device for medical oxygen generator band liquid storage function.

Concrete technical scheme is as follows:

A kind of exhaust and muffler tube of medical oxygen generator, including outer tube, inner tube, said inner tube be at least 3 mutual tangent and The hollow cylindrical tube tangent with described outer tube wall；Described outer tube includes 3 layers, and inside and outside two-layer is noise reduction steel plate and makes, middle Layer is silencing cotton packed layer；The noise reduction gas running through described outer tube wall and silencing cotton packed layer is had on the inwall of described outer tube Room；Said inner tube is 3-tier architecture, and inside and outside two-layer is that noise reduction steel plate is made, and intermediate layer is described silencing cotton packed layer；Said inner tube On uniformly offer the air-flow through hole running through said inner tube；

Preferably, described outer tube is identical with said inner tube length；

Preferably, before and after described outer tube, two-port is respectively air inlet and gas outlet；

Preferably, described air inlet is corrugated tubing structure, for being connected to the electromagnetic valve of medical oxygen generator；

Preferably, described gas outlet is outwardly open bell-mouth structure of air.

Beneficial effect:

Present configuration is simple, when exhaust airstream is after air inlet enters inner tube, and a part is expelled directly out by inner tube, one Lease making is crossed air-flow through hole and is entered outer tube bore, when outer tube bore pressure increases and is more than the pressure in inner tube, in outer tube bore Air-flow can reenter inner tube and discharge, the path of air-flow when adding aerofluxus is so set, makes the reduced velocity flow of air-flow, delay Slow discharge, reaches the effect of aerofluxus noise abatement, and inner and outer tubes are 3 layers simultaneously, and inside and outside two-layer is noise reduction steel plate and makes, in Interbed is silencing cotton packed layer, and air-flow is through inner and outer tubes, and sound is effectively isolated absorption, thus reaches the mesh of noise reduction 's.

Accompanying drawing explanation

In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to Other accompanying drawing is obtained according to these accompanying drawings.

The gas-discharging silencing tube cross-sectional view of Fig. 1: medical oxygen generator；
