Description

Technical Field

[0001] The utility model relates to the field of oxygen generator control, in particular to a gas control device for a portable oxygen generator. Background Art

[0002] People are increasingly pursuing the miniaturization and portability of products. However, after the equipment is miniaturized, the internal space is narrow. Currently, in the industry, adsorption towers, valve bodies, and sensors are traditionally connected by pipelines. Multiple pipelines are respectively used to connect the adsorption tower, throttle, backflush valve, oxygen storage tank, breathing valve, oxygen concentration sensor, and oxygen outlet, etc. Due to considerations of pipeline connection, bending risk, and large space occupation, air leakage is likely to occur.

[0003] For example, the Chinese patent with the publication number CN207877256U discloses a portable air purification oxygen generator. The oxygen generator includes: a housing, an air filter chamber, an air compressor, a molecular sieve tower, an essential oil drip filter, and a power module are installed in the housing. An air inlet is provided at the bottom end of the air filter chamber, an air filter screen is arranged in the air filter chamber, the air filter chamber is connected to the air compressor through a gas pipeline, the air compressor is connected to the power module through a wire, the air compressor is connected to the bottom of the molecular sieve tower through a gas pipeline, an exhaust gas discharge pipe is further provided at the bottom of the molecular sieve tower, the top of the molecular sieve tower is connected to the essential oil drip filter through a gas pipeline, and an oxygen discharge pipe is provided at the top end of the essential oil drip filter. By filtering the air and then separating oxygen and nitrogen, and adding volatile essential oils, people can inhale essential oils with different effects, so as to achieve the purpose of extracting air into pure oxygen at any time and having different effects on the human body according to the replaced essential oils, which is convenient to carry.

[0004] To sum up, there are many drawbacks in the control devices of existing portable oxygen generators. Due to the pipeline connection involved, there is a risk of bending, and it occupies a large space, which easily leads to air leakage. At the same time, there are many product parts, which will cause an increase in material costs and a decrease in assembly efficiency. Summary of the Utility Model

There are two air channels in the gas path main body 1. The adsorption tower interface 2 is arranged on the gas path main body 1, and there are two adsorption tower interfaces 2, corresponding to the two air channels respectively. The throttle 3 is arranged inside the gas path main body 1 and corresponds to the position of the adsorption tower interface 2 respectively. The backflush valve 4 is arranged on the gas path main body 1. The throttle 3 and the backflush valve 4 perform backflush desorption of nitrogen and oxygen on the oxygen at the adsorption tower interface 2. The one-way valve 5 is arranged in the gas path main body 1. The oxygen storage tank 11 interface 8 is arranged on the gas path main body 1 and is connected to the one-way valve 5.
