Property layer with the water in air and oxygen generation electrochemical reaction.
The utility model can be further arranged to, and described outer tube diameter is more than the diameter of inner tube, and the two of described outer tube
Hold at closing in, to be tightly connected at described closing in described outer wall of inner tube, closed guarantor is formed at outer tube, inner tube and closing in
Warm layer.
By using above-mentioned technical proposal, outer tube diameter be more than inner tube diameter inner tube can be inserted in, outer tube, inner tube and
Closed heat-insulation layer is formed at closing in, it is to avoid inert gas is revealed, keep the heat insulation effect of insulating tube.
The utility model can be further arranged to, and described inner tube is stainless steel.
By using above-mentioned technical proposal, stainless steel is corrosion-resistant, and hardness height is hardly damaged, and makes the service life of inner tube
It is longer.
The utility model can be further arranged to, and described rigid layer is stainless steel.
By using above-mentioned technical proposal, stainless steel is corrosion-resistant, and hardness height is hardly damaged, and makes the use longevity of rigid layer
Life is longer.
The utility model can be further arranged to, and described flexible layer is polyethylene material.
By using above-mentioned technical proposal, there is polyethylene material well flexible and wear-resisting to be hardly damaged, and make flexible layer
Service life it is longer.
The utility model can be further arranged to, and described inner tube is shaped as the inner tube of circle.
The utility model can be further arranged to, and described outer tube is shaped as the outer tube of circle.
The utility model can be further arranged to, and be welded at described outer tube, inner tube and closing in.
By using above-mentioned technical proposal, welding has good seal at outer tube, inner tube and closing in, it is to avoid indifferent gas
Body is lost in, and keeps the heat insulation effect of insulating tube.
In summary, the utility model has the advantages that：
Filling inert gas in support formation heat-insulation layer, heat-insulation layer is set to play a part of insulation between inner and outer tubes,
Outer tube includes rigid layer and flexible layer simultaneously, and rigid layer has larger hardness, is hardly damaged when being contacted firmly with other objects, soft
Property layer in the outside of rigid layer, protection can be played a part of to rigid layer, and avoid rigid layer and the water and oxygen in air
Electrochemical reaction occurs for gas, and inner tube can be inserted in by the diameter that outer tube diameter is more than inner tube, form close at outer tube, inner tube and closing in
The heat-insulation layer closed, it is to avoid inert gas is revealed, keeps welding with good at the heat insulation effect of insulating tube, outer tube, inner tube and closing in
Good seal, it is to avoid inert gas is lost in, keeps the heat insulation effect of insulating tube.
