[0047] Example 2

[0048] like Figures 1 to 8 As shown, this embodiment provides another horizontal liquid oxygen storage, conversion and oxygen supply device, whose structure includes all the contents of embodiment 1, and only the different parts are described below.

[0049] In this embodiment, a flow regulator 10 is further included. The flow regulator 10 is arranged on the gasification diffusion pipe 20 . The flow meter 10 is used to adjust the oxygen flow rate of the diffusion port 12 . The flow meter 10 is embedded in the side wall of the shell 1 .

[0050] In this embodiment, it should be noted that a liquid level gauge 11 and a pressure gauge 9 are also included. The liquid level gauge 11 is arranged on the liquid oxygen mother tank 13. The liquid level gauge 11 is used to display the liquid level in the liquid oxygen mother tank 13. Specifically, the liquid level gauge 11 adopts a capacitive liquid level gauge. The liquid level gauge 11 is connected to the sensor in the liquid oxygen mother tank 13 through a liquid level pipeline 24. The display of the liquid level gauge 11 is embedded in the side wall of the housing 1.

[0051] The pressure gauge 9 is used to display the gas pressure in the liquid oxygen mother tank 13 . Specifically, the pressure gauge 9 is embedded in the side wall of the shell 1 , and the pressure gauge 9 is arranged at one end of the pressure tube 22 .

[0052] Furthermore, it also includes an energy-saving valve 19, and the pressure relief pipe 23 is connected to the gasification diffusion pipe 20 through the energy-saving valve 19. The energy-saving valve 19 is used to control the connection and closing between the pressure relief pipe 23 and the gasification diffusion pipe 20. During use, when the air pressure in the pressure relief pipe 23 reaches 0.11MPa or more (at this time, the air pressure is less than the pressure relief value of the safety valve 18, and the safety valve 18 is in a closed state), the energy-saving valve 19 automatically opens to connect the pressure relief pipe 23 with the gasification diffusion pipe 20. In this state, the entire device can be connected through the pressure relief pipe 23 using liquid The oxygen vaporized in the oxygen mother tank 13 is used for oxygen supply; when the air pressure in the pressure relief pipe 23 is less than 0.11MPa, the energy-saving valve 19 is automatically closed, and the pressure relief pipe 23 is disconnected from the gasification diffusion pipe 20. In this state, the entire device vaporizes the liquid oxygen in the liquid oxygen mother tank 13 through the gasification diffusion pipe 20 and then diffuses it to supply oxygen; by setting the energy-saving valve 19, the gaseous oxygen and liquid oxygen in the liquid oxygen mother tank 13 can be fully utilized under different conditions, avoiding the gaseous oxygen in the liquid oxygen mother tank 13 can only be discharged through the safety valve 18, resulting in waste;

[0053] The end of the pressure tube 22 facing away from the pressure gauge 9 is connected to the vaporization diffusion pipe 20 and the pressure relief pipe 23 through the energy-saving valve 19. When the pressure tube 22 is connected to the pressure relief pipe 23 through the energy-saving valve 19, the air pressure in the liquid oxygen mother tank 13 can be measured; when the pressure tube 22 is connected to the vaporization diffusion pipe 20 through the energy-saving valve 19, the air pressure in the vaporization diffusion pipe 20 can be measured.

[0054] During use, the filling steps of the liquid oxygen mother tank 13 are as follows:

[0055] 1. Connect the liquid oxygen filling head of the liquid oxygen source to the liquid oxygen filling port 6;

[0056] 2. Rotate the filling stop valve handle 17 by 90 degrees to close the sub-tank filling stop valve 7, open the filling exhaust valve 5, and then turn on the liquid oxygen source switch for filling;

[0057] 3. Observe the value of the liquid level gauge 11 until it is fully filled, then turn off the liquid oxygen source switch and stop filling;

[0058] 4. Close the filling and exhaust valve 5 and the filling is completed.

[0059] The technical effect achieved by this embodiment is as follows: by setting the flow meter 10, the oxygen supply flow rate of the diffusion port can be flexibly adjusted; by setting the liquid level meter 11 and the pressure gauge 9, the liquid level in the liquid oxygen mother tank 13 and the pressure in the gasification diffusion pipe 20 can be easily observed.

[0060] Example 3

[0061] like Figures 1 to 8 As shown, this embodiment provides another horizontal liquid oxygen storage, conversion and oxygen supply device, whose structure includes all the contents of embodiment 1, and only the different parts are described below.

[0062] In this embodiment, a liquid oxygen sub-tank 3 is also included. The liquid oxygen sub-tank 3 is adapted to the sub-tank filling mechanism, and the number of the liquid oxygen sub-tanks 3 can be set to multiple. The liquid oxygen sub-tank 3 adopts an existing structure, and its specific structure is not repeated here.

[0063] The filling head mechanism includes a sub-tank filling pipe 16, a sub-tank filling pressing wrench 8, a connecting seat 25, a sub-tank exhaust ejector 26, a sub-tank liquid oxygen filling head 27, a fixing seat 28 and a slide rail 29. One end of the sub-tank filling pipe 16 is connected to the main end pipe 15, and the other end of the sub-tank filling pipe 16 is connected to the sub-tank liquid oxygen filling head 27. The sub-tank filling pipe 16 is provided with a sub-tank filling stop valve 7;

[0064] The sub-tank liquid oxygen filling head 27 and the sub-tank exhaust ejector 26 are both vertically arranged on the fixed seat 28, the sub-tank liquid oxygen filling head 27 and the sub-tank exhaust ejector 26 are biaxially parallel and coplanar, the slide rail 29 is vertically arranged on the inner wall of the sub-tank filling bin 2, and the fixed seat 28 is slidably arranged on the slide rail 29;

[0065] The sub-tank filling pressing wrench 8 is vertically arranged, and the sub-tank filling pressing wrench 8 is connected to the fixing seat 28 through the connecting seat 25. After the sub-tank filling pressing wrench 8 is pressed down, the fixing seat 28 can be driven to move downward.

[0066] In the present embodiment, it should be noted that the filling stop valve handle 17 and the handle of the sub-tank filling pressing wrench 8 are both located outside the top of the shell 1. The filling stop valve handle 17 is detachable and can be removed and put aside when not in use to prevent misoperation. During use, the liquid oxygen sub-tank 3 is placed in the sub-tank filling bin 2, and its filling port and exhaust port are respectively aligned with the sub-tank liquid oxygen filling head 27 and the sub-tank exhaust ejector pin 26, and then the sub-tank filling pressing wrench 8 is pressed down so that it rotates without rebounding. This is linked filling. When the sub-tank filling pressing wrench 8 is pressed down, liquid oxygen can be filled and the pressure in the tank can be discharged. When liquid oxygen splashes at the filling port or exhaust port of the liquid oxygen sub-tank 3, it is full. At this time, hold the sub-tank filling pressing wrench 8 and rotate it to make it rebound and separate it from the liquid oxygen sub-tank 3. During use, the liquid oxygen sub-tank 3 cannot be tipped over or turned upside down, and a large amount of liquid oxygen must be prevented from splashing onto the skin.

[0067] The technical effect achieved by this embodiment is as follows: the filling head mechanism adopts linked filling, and can discharge the gas in the liquid oxygen sub-tank 3 while pressing down, and respond at the same time, which can speed up the filling speed; the main end pipe 15 can realize the liquid oxygen filling in the liquid oxygen mother tank 13, the gasification and diffusion oxygen supply of the liquid oxygen in the liquid oxygen mother tank 13, and the liquid oxygen filling in the liquid oxygen sub-tank 3. The main end pipe 15 realizes "one pipe for three uses", integrating the mother tank filling pipeline, the gasification pipeline and the sub-tank filling pipeline, greatly reducing the space occupancy, while reducing the welding points, ensuring the stability of the system, and realizing independent work without interfering with each other by opening and closing the corresponding valves.

[0068] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.

[0069] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of implementation of the present invention without substantially changing the technical content.
