Description

Technical Field

[0001] The present invention relates to the technical field of oxygen supply devices, and particularly relates to a liquid oxygen storage converter. Background Art

[0002] The air is thin on the plateau. As the altitude increases, the partial pressure of oxygen in the air gradually decreases, making it difficult to meet the normal oxygen supply needs of the human body. This can easily lead to hypoxia, causing multi-functional disorders of the body and even endangering life. Especially when the activity intensity increases during work and life in plateau areas, the oxygen consumption of the brain and body increases, which can easily exacerbate the plateau hypoxia reaction, resulting in difficulty in breathing and a significant decline in thinking reaction and physical endurance. By inhaling gas with an oxygen concentration higher than that of air, human hypoxia can be corrected, and the levels of arterial oxygen partial pressure and oxygen saturation can be increased.

[0003] In existing liquid oxygen storage and supply devices, the heat exchange area between the storage tank body and the filling valve body and the outside world is relatively large. After liquid oxygen is filled, in the non-use state, the liquid oxygen inside the tank will continuously vaporize after heat exchange with the outside world. To prevent the tank from being pressurized, the vaporized oxygen in the tank will be automatically discharged through the safety valve after reaching a certain air pressure, resulting in a large amount of liquid oxygen waste. At the same time, the storage period of liquid oxygen is relatively short, which is not conducive to popularization and use. Summary of the Invention

DETAILED DESCRIPTION

[0032] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] like Figures 1 to 6 As shown, a liquid oxygen storage converter in an embodiment of the first aspect of the present invention comprises a storage tank 9, a valve body 11, a filling pipe 12, an exhaust pipe 16, a vaporization pipe 10 and an oxygen supply end pipe 7, a filling hole and an exhaust hole are arranged in the valve body 11, the filling hole and the exhaust hole are arranged in parallel with each other, the filling hole and the exhaust hole both penetrate the valve body 11, and valve core assemblies are arranged in the filling hole and the exhaust hole, and the filling hole and the exhaust hole respectively control the opening and closing of their internal channels through their respective valve core assemblies, and the valve core assembly adopts an existing mechanism, and its specific structure is not repeated here, a filling port 6 is arranged at the top of the filling hole, and an exhaust port 8 is arranged at the top of the exhaust hole;

[0035] The storage tank 9 is a double-layer structure. The valve body 11 is arranged on the top of the storage tank 9. The top end of the filling pipe 12 is connected to the bottom end of the filling hole. The bottom end of the filling pipe 12 passes through the tank wall of the storage tank 9 and extends into the storage cavity in the storage tank 9. The filling pipe 12 is used to guide the liquid oxygen into the storage tank 9 during the filling process. Figure 6 As shown, a section of the filling pipe 12 located in the storage chamber is provided with a bent portion, so that the liquid oxygen in the storage chamber is not easy to flow back into the valve body 11 along the filling pipe 12 when placed horizontally or tilted;

[0036] One end of the exhaust pipe 16 is connected to the bottom end of the exhaust hole, and the other end of the exhaust pipe 16 is connected to the storage chamber in the storage tank 9. An exhaust safety valve 17 is provided on the exhaust pipe 16. When the pressure in the storage tank 9 is too high during use, the exhaust safety valve 17 will be pushed open to automatically exhaust and release the pressure; when filling liquid oxygen, the filling head is inserted into the filling port 6 and pushes down the corresponding valve core assembly to open the internal channel of the filling hole. At the same time, the linkage ejector pin on the filling head is inserted into the exhaust port 8 to push down the corresponding valve core assembly to open the internal channel of the exhaust hole, so that the internal and external air pressures of the storage tank 9 are consistent, so as to facilitate the rapid filling of liquid oxygen; after the filling is completed and the filling head is removed, the corresponding valve core assemblies in the filling hole and the exhaust hole automatically rebound and close the corresponding channels.

[0037] One end of the vaporization tube 10 is connected to the oxygen supply end tube 7, and a valve 5 is provided between the oxygen supply end tube 7 and the vaporization tube 10. The valve 5 is a manual valve, and the other end of the vaporization tube 10 is connected to the storage cavity in the storage tank 9. The vaporization tube 10 is spiral, and the vaporization tube 10 is wound around the outer peripheral side of the valve body 11. After the valve 5 is opened during use, the liquid oxygen in the storage tank 9 can slowly enter the vaporization tube 10 to absorb heat, vaporize and heat up, and finally supply oxygen to the outside through the oxygen supply end tube 7.

[0038] In this embodiment, it should be noted that Figure 1 As shown, it also includes a shell 1, which is cylindrical, and the valve body 11 and the storage tank 9 are both arranged in the shell 1. The shell 1 is provided with a plurality of heat exchange holes; the shell 1 is provided with corresponding through holes at positions corresponding to the filling port 6, the exhaust port 8 and the oxygen supply end pipe 7, and the control handle of the valve 5 is located outside the shell 1;

[0039] A handle 2 is provided on the shell 1, and the handle 2 is arranged along the length direction of the shell 1. Connecting rings 3 are respectively provided at both ends of the handle 2. The connecting rings 3 are sleeved on the shell 1, and a base 4 is provided on the side of the connecting ring 3 away from the handle 2. The base 4 is used to provide stable support when the entire device is placed horizontally.

[0040] The technical effects achieved by this embodiment are as follows: The storage tank 9 has a double-layer structure, with better heat insulation performance. In the non-use state, it is not easy for the inside of the storage tank 9 to exchange heat with the outside, which can effectively slow down the heat absorption and vaporization of the liquid oxygen in the storage tank 9 and extend the storage time of the liquid oxygen; there is no direct contact between the storage cavity in the storage tank 9 and the valve body 11. In the non-use state, the heat exchange area between the storage cavity in the storage tank 9 and the outside is greatly reduced, which can effectively reduce the heat absorption and vaporization of the liquid oxygen in the storage cavity in the non-use state, reduce the waste of liquid oxygen, and thus greatly extend the storage period of the liquid oxygen; in the use state, the liquid oxygen can enter the vaporization tube to absorb heat and gradually vaporize and heat up, and then supply oxygen to the outside through the oxygen supply end pipe. On the premise of ensuring normal oxygen supply, the whole device greatly reduces the waste of liquid oxygen during storage and transportation, so that the liquid oxygen has a long storage period and is convenient for popularization and use; the whole device can be used normally whether it is placed vertically or horizontally, and the vaporization amount of the liquid oxygen is stable during use.

[0041] Embodiment 2

[0042] As Figures 1 to 6 shown, another liquid oxygen storage and converter provided in this embodiment has a structure including all the contents of Embodiment 1, and only the different parts will be described below.

[0043] In this embodiment, there is a gap between the valve body 11 and the storage tank 9.

[0044] In this embodiment, it should be noted that, as Figure 4 shown, it further includes a mounting seat 22, and the valve body 11 is mounted on the mounting seat 22; specifically, the mounting seat 22 is disc-shaped, the bottom of the valve body 11 is connected to the mounting seat 22 by bolts, and there are a plurality of support columns 23 between the mounting seat 22 and the storage tank 9. Both ends of the support column 23 are respectively connected to the mounting seat 22 and the storage tank 9 by bolts.

[0045] The technical effects achieved by this embodiment are as follows: There is a gap between the valve body 11 and the storage tank 9, which greatly reduces the heat exchange area between the storage cavity in the storage tank 9 and the outside, can effectively reduce the heat absorption and vaporization of the liquid oxygen in the storage cavity in the non-use state, reduce the waste of liquid oxygen, and extend the storage period of the liquid oxygen.

[0046] Embodiment 3

[0047] As Figures 1 to 6 shown, another liquid oxygen storage and converter provided in this embodiment has a structure including all the contents of Embodiment 2, and only the different parts will be described below.

[0048] In this embodiment, it further includes an oxygen supply pipe 13. The oxygen supply pipe 13 has a double-layer structure. Specifically, the oxygen supply pipe 13 includes an inner pipe 18 and an outer pipe 21, and the outer pipe 21 is sleeved outside the inner pipe 18;

[0049] One end of the inner tube 18 is connected to the end of the gasification tube 10 away from the oxygen supply end tube 7, and the other end of the inner tube 18 passes through the storage tank 9 and extends to the bottom of the storage cavity. The end of the inner tube 18 located at the bottom of the storage cavity is L-shaped;

[0050] One end of the outer tube 21 is communicated with the exhaust pipe 16 and the gasification pipe 10 respectively, and the other end of the outer tube 21 passes through the storage tank 9 and extends to the top of the storage chamber.

[0051] In the present embodiment, it should be noted that an adapter 14 is also included. The adapter 14 is arranged at one end of the outer tube 21 outside the storage tank 9. The adapter 14 is provided with a first port, a second port and a third port which are interconnected. The first port is connected to the outer tube 21, the second port is connected to the exhaust pipe 16, and the third port is connected to the gasification pipe 10 through the connector 15. A safety valve is provided between the third port and the connector 15.

[0052] Furthermore, the working principle of the entire device is as follows. When filling liquid oxygen, the filling head is inserted into the filling port 6 and pushes down the corresponding valve core assembly to open the internal channel of the filling hole. At the same time, the linkage push pin on the filling head is inserted into the exhaust port 8 to push down the corresponding valve core assembly to open the internal channel of the exhaust hole, so that the internal and external air pressures of the storage tank 9 are consistent, and the liquid oxygen flows into the storage cavity through the filling hole and the filling tube 12 in turn, and the gas in the storage cavity is discharged to the outside of the storage cavity through the outer tube 21, the exhaust pipe 16 and the exhaust port 8 in turn until the liquid oxygen is filled. After the filling is completed and the filling head is removed, the corresponding valve core assemblies in the filling hole and the exhaust hole automatically rebound and close the corresponding channels.

[0053] When not in use, the liquid oxygen in the storage chamber will slowly gasify to form oxygen. When the air pressure in the storage chamber exceeds the safe value, the oxygen in the storage chamber will flow along the outer tube 21 to the exhaust pipe 16 and push open the exhaust safety valve to automatically exhaust and release pressure until the air pressure in the storage chamber drops to a safe range.

[0054] In the use state, the valve 5 is opened. When the oxygen pressure in the storage chamber is relatively low, the liquid oxygen in the storage chamber flows into the vaporization pipe 10 along the inner pipe 18 under the action of the oxygen pressure, and is heated up by absorbing heat through the vaporization pipe 10, and then is supplied to the outside through the oxygen supply end pipe 7; when the oxygen pressure in the storage chamber is relatively high (but less than the air pressure safety value in the storage chamber), when the gaseous oxygen in the storage chamber drives the liquid oxygen to flow out along the inner pipe 18, part of the gaseous oxygen will reach the connector 15 along the outer pipe 21, push open the safety valve and enter the vaporization pipe 10, and then supply oxygen to the outside through the oxygen supply end pipe, thereby making full use of the gaseous oxygen and liquid oxygen in the storage chamber.

[0055] The technical effect achieved by this embodiment is that the oxygen supply pipe 13 adopts a double-layer structure, which can reduce the number of openings on the storage tank 9, and the overall structure can fully utilize the gaseous oxygen and liquid oxygen in the storage cavity, thereby reducing waste.

[0056] Example 4

[0057] As Figures 1 to 6 shown, another liquid oxygen storage converter provided in this embodiment has a structure including all the contents of Embodiment 3, and only different parts will be described below.

[0058] In this embodiment, the storage tank 9 includes an inner tank body 19 and an outer tank body 20. The outer tank body 20 is sleeved outside the inner tank body 19. The interlayer between the inner tank body 19 and the outer tank body 20 is vacuum, and it has good heat preservation and heat insulation performance.

[0059] In this embodiment, it should be noted that, as Figure 6 shown, a section of the oxygen supply pipe 13 located between the inner tank body 19 and the outer tank body 20 is arc-shaped. In the non-use state, when the storage tank 9 is placed horizontally or tilted, the liquid oxygen in the storage cavity is not likely to flow along the oxygen supply pipe 13 to the outside of the storage tank 9, thereby reducing the heat exchange between the liquid oxygen in the storage tank 9 and the outside world in the non-use state, and preventing the waste caused by the rapid gasification and discharge of the liquid oxygen in the non-use state.

[0060] Although the present invention has been described in detail with general descriptions and specific embodiments above, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.

[0061] Terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of clear narration and are not used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present invention.
