[0033] In the embodiment, the end of inner tube extension pipe 8 and the end of outer tube extension pipe 9 are projected symmetrically distributed on both sides of the center of the cross section of tank 2, and are all located at the position close to the vertical inner wall of tank 2, so that when tipping occurs, the end of inner tube extension pipe 8 and the end of outer tube extension pipe 9 are always located in gaseous oxygen.

[0034] When using the embodiment, as Figure 1 And Figure 3 Indicated, under normal circumstances, the end of inner tube extension pipe 8 is located in liquid oxygen 1, and the end of outer tube extension pipe 9 is located in gaseous oxygen, at this time, liquid oxygen 1 is gasified via second gasification coil pipe 6, and gaseous oxygen is directly discharged from first gasification coil pipe 5, and finally converges to gas outlet pipe 7.

[0035] When tipping occurs, in one case, as Figure 4 Indicated, the end of inner tube extension pipe 8 is located in liquid oxygen 1, and the end of outer tube extension pipe 9 is located in gaseous oxygen, at this time, liquid oxygen 1 is gasified via second gasification coil pipe 6, and gaseous oxygen is directly discharged from first gasification coil pipe 5, and finally converges to gas outlet pipe 7.

[0036] In another case, as Figure 5As shown, the end of the inner tube extension tube 8 is located inside the gaseous oxygen, and the end of the outer tube extension tube 9 is located inside the liquid oxygen 1. At this time, the gaseous oxygen is discharged directly from the second vaporization coil 6, and the liquid oxygen 1 is vaporized through the first vaporization coil 5 and finally merges into the outlet tube 7.

[0037] Regardless of the state, the leakage of liquid oxygen 1 was prevented.

[0038] Example 2

[0039] like Figures 1-5 As shown, an anti-tipping liquid oxygen supply device includes a tank 2 containing liquid oxygen 1, and an exhaust outer pipe 3 and an exhaust inner pipe 4 disposed outside the tank 2.

The inner end of the exhaust outer pipe 3 is located at the upper part of the tank 2 and is connected to an outer pipe extension pipe 9 extending to the upper side of the tank 2.

[0040] Specifically, in this embodiment, the cross-section of the tank 2 is elliptical. When the tank 2 is placed horizontally, the end of the inner tube extension pipe 8 and the end of the outer tube extension pipe 9 are located at the upper and lower parts, or the lower and upper parts, of the tank 2, respectively.

At this time, the liquid oxygen 1 is vaporized through the second vaporization coil 6, and the gaseous oxygen is directly discharged from the first vaporization coil 5, eventually merging into the outlet tube 7.

[0042] When tipping occurs, because the cross-section of tank 2 is elliptical, it will only tip in two directions. In one case, such as... Figure 4 As shown, the end of the inner tube extension tube 8 is located inside the liquid oxygen 1, and the end of the outer tube extension tube 9 is located inside the gaseous oxygen. At this time, the liquid oxygen 1 is vaporized through the second vaporization coil 6, and the gaseous oxygen is directly discharged from the first vaporization coil 5, eventually merging into the outlet tube 7.

[0043] In another case, such as Figure 5 As shown, the end of the inner tube extension tube 8 is located inside the gaseous oxygen, and the end of the outer tube extension tube 9 is located inside the liquid oxygen 1. At this time, the gaseous oxygen is discharged directly from the second vaporization coil 6, and the liquid oxygen 1 is vaporized through the first vaporization coil 5 and finally merges into the outlet tube 7.

[0044] Regardless of the condition, the leakage of liquid oxygen 1 was prevented.

[0045] In the above embodiment, the part of the exhaust inner pipe 4 inside the exhaust outer pipe 3 keeps a distance with the inner wall of the exhaust outer pipe 3, which facilitates the flow of liquid oxygen and gaseous oxygen. Meanwhile, the position of the exhaust outer pipe 3 where the exhaust inner pipe 4 is inserted or extracted keeps sealed with the exhaust inner pipe 4, avoiding the mixing of liquid oxygen and gaseous oxygen between the exhaust outer pipe 3 and the exhaust inner pipe 4.

[0046] In the above embodiment, in the tank body 2, the position of the exhaust outer pipe 3 where the exhaust inner pipe 4 is extracted is provided with an elbow joint 10, the exhaust inner pipe 4 is extracted from the elbow joint 10, and the outer pipe extension pipe 9 is connected with the elbow joint 10, which facilitates the installation.

[0047] In the above embodiment, the first gasification coil pipe 5 is surrounded outside the second gasification coil pipe 6, the number of rings of the first gasification coil pipe 5 is less than that of the second gasification coil pipe 6, and the first gasification coil pipe 5 is located at the lower half of the second gasification coil pipe 6, the inner diameter of the second gasification coil pipe 6 is greater than that of the first gasification coil pipe 5, which facilitates the gaseous oxygen to be discharged through the exhaust outer pipe 3 and the first gasification coil pipe 5 and the liquid oxygen 1 to be discharged after being gasified through the exhaust inner pipe 4 and the second gasification coil pipe 6 in most cases.

[0048] The anti-toppling liquid oxygen oxygen supply device of the utility model, when the liquid oxygen oxygen supply device tilts to any side, always keeps a exhaust pipe above the liquid level line, plays the role of exhaust and balance internal air pressure, avoids the overflow of liquid oxygen in the state of tilting, efficiently and reliably guarantees the personal safety, through two gasification coil pipes, even if the liquid oxygen 1 overflows from the tank body 2, can also be gasified in time.
