TECHNICAL FIELD

[0001] The utility model relates to liquid oxygen oxygen supplier technical field, concretely relates to a liquid oxygen oxygen supplier with flow guide pipe. BACKGROUND

[0002] With the increase of altitude on the plateau, the oxygen content of air also decreases accordingly. For example, the average altitude of Qinghai-Tibet Plateau is above 4000 meters, the air is thin, the air pressure is low, and the normal oxygen supply demand of human body cannot be met, thereby causing hypoxia to cause multiple dysfunction of the body and even endanger life.

[0003] Especially when engaged in field work, with the increase of physical strength, more oxygen is consumed, and the plateau hypoxia reaction is more aggravated, the physical fitness is obviously decreased, and breathing is difficult. The plateau sickness causes different degrees of harm to the human body, and even causes death when the hypoxia is serious.

[0004] At present, the main oxygen supply device on the market is to use gaseous oxygen bag to supply oxygen or air concentration to supply oxygen. The defects of the two ways are that the occupied space is large, the oxygen capacity is small, an additional power supply is needed, and it is not convenient to carry for a long time in the field. The use of liquid oxygen oxygen supplier can meet the demand of lightness and large capacity.

[0005] However, the boiling point of liquid oxygen is low, which is-183 DEG C under normal pressure. When filling liquid oxygen into the liquid oxygen oxygen supplier, since the filling pipe is connected, the external heat is easy to conduct into the liquid oxygen oxygen supplier through the filling pipe, causing the volatilization of the internal liquid oxygen.

[0008] Preferably, the sandwich layer is vacuum, and almost no gas molecules exist, so that heat is difficult to transfer through conduction, radiation and convection.

[0009] Preferably, the flow guide pipe is connected with the filling pipe after being surrounded at the position close to the inner wall of the outer shell, and the length of the flow guide pipe is as long as possible.

[0010] Preferably, the flow guide pipe is zigzag-shaped, and is connected with the filling pipe after multiple reciprocating bending, so as to extend the length of the flow guide pipe as much as possible.

[0011] Preferably, the flow guide pipe is a coil pipe, and the starting point of the coil pipe is located at the center and is connected with the filling joint, and the ending point of the coil pipe is located at the outermost circle and is connected with the filling pipe, so as to extend the length of the flow guide pipe as much as possible.

[0012] Preferably, the wall thickness of the flow guide pipe is 0.4-0.6 mm, and the inner diameter is 5-6 mm, so as to make the size of the flow guide pipe as small as possible without causing blockage to the liquid oxygen flow channel.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The flow guide pipe is arranged, so that heat is effectively prevented from being conducted into the liquid oxygen oxygen supplier along the filling pipe, and the volatilization of the liquid oxygen is reduced.

[0015] 2. The vacuum interlayer is arranged, so that heat is difficult to be transmitted through conduction, radiation and convection.
