Description
Technical field
The present invention relates to Domestic oxygen erator, the oxygenerator of a kind of replaceable molecule tower and seperating vale is specifically referred to.
Background technology
As the further development of network is popularized, the combination of medical industry and internet is more and more closer, more and more use
By Online Shopping product, this also determines that the region distance between manufacturer and user is big, and distance is remote for family selection,
Country is even crossed over, undoubtedly this is also directly to increased after sale difficulty.And for oxygenerator, volume is big, weight weight, fortune
It is defeated with high costs, while internal structure is also unsuitable for repeatedly transport, so Cost Problems after sale are also just highlighted.
In PSA adsorption method of separation oxygen generation systems, molecule tower and seperating vale are a rings of core, but in existing PSA technology
In, the two core members are also life problems or failure most often occur.Molecular sieve to the air quality requirements of use environment compared with
Height, dust, greasy dirt, humidity can all cause its life-span to shorten significantly, be dashed forward in this atmosphere pollution increasingly serious, city haze problem
Under the overall situation for going out, the molecular sieve life-span also inevitably has a greatly reduced quality；And seperating vale, it is whether rotary to separate or relay
Device is separated, and has respective technical bottleneck, while can also be influenceed by air quality, and different degrees of quality problems occurs.
As shown in figure 1, existing oxygenerator molecule tower and seperating vale are empty with air intake filter, intake muffler, oil-free
Press, oxygen container, pressure regulator valve and flowmeter etc. are arranged in shell together, the oxygenerator prepared by the technical scheme, when point
When sub- tower or seperating vale quality problems occur and need repairing or change, generally, if there is matter in above-mentioned two core members
Amount problem, needs to be changed more, then this kind of structure has following deficiency：1st, need user that whole oxygenerator is returned into production
Producer, molecule tower or seperating vale are dismantled, repaired and are changed by the specialized maintenance personnel in manufacturer, and it posts machine back and forth
Cost of transportation it is high；2nd, for a user, it is necessary to machine first is returned into manufacturer, after then being changed by manufacturer's maintenance
Return again, user needs to wait the haulage time of two distances back and forth can just be continuing with oxygenerator, and period of reservation of number is long.Cause
How this, avoided or reduced the high physical distribution expenses brought by the quality problems of oxygenerator, after cost is reduced, while quickly
Help user to solve quality problems, improve satisfaction after sale, also just become an important topic of oxygenerator industry.
