[0024] Example 1

[0025] A smart integrated gas cylinder drying and vacuuming device includes a second housing 9, with a first housing 1 hinged to the outside of the second housing 9. To facilitate opening the first housing 1, a handle 7 is provided on the surface of the first housing 1. The first housing 1 and the second housing 9 are closed by a snap-fit ​​mechanism for easy opening or closing. Multiple sets of first semi-circular grooves 10 are provided at the upper end of the first housing 1, and a second semi-circular groove 11 is provided on the rear side of the first semi-circular groove 10. The second semi-circular groove 11 is provided on the second housing 9. Support plates 2 are provided on both sides of the upper end of the second housing 9, and a third fixing plate 15 is provided between the support plates 2. Multiple sets of vacuum pumps 5 are provided on the third fixing plate 15, corresponding to the first semi-circular grooves 10. One end of a flexible hose 6 is connected to the port of the vacuum pump 5. The other end of the flexible hose 6 passes through the third fixing plate 15 and is connected to one end of a rigid pipe 12. The other end of the rigid pipe 12 is rotatably connected to a connector 13. The inner wall of the connector 13 is provided with threads, and the outside of the connector 13 is provided with an opening and closing mechanism 3.

[0026] In this embodiment, in order to dry the gas cylinder and remove internal moisture, multiple sets of electric heating tubes 8 are installed inside the second box 9 and the first box 1.

[0027] Specifically, firstly, open the first chamber 1 and place multiple gas cylinders sequentially into the bottom of the second chamber 9, positioned within the second semi-circular groove 11. Then, close the first chamber 1, causing the first semi-circular groove 10 of the first chamber 1 to engage with the outside of the gas cylinders. This secures the gas cylinders firmly and reliably, and the fixing is quick and easy. After fixing, align the connector 13 with the gas cylinder port and rotate the connector 13 to connect and secure it. Finally, turn on the vacuum pump 5 to evacuate the gas cylinders through the hose 6, rigid pipe 12, and connector 13, while the external heating element 8 heats and dries the gas cylinders. The internal moisture evaporates, forming water vapor, allowing the vacuum pump 5 to remove both water vapor and internal impurities, achieving efficient cleaning and avoiding the drawbacks of impure filling gas. Furthermore, it can evacuate multiple gas cylinders at once, making it highly efficient and convenient to use.

[0028] Example 2

[0029] As an alternative, an intelligent integrated gas cylinder drying and vacuuming device includes an opening and closing mechanism 3 comprising a fixed frame 311 fixed to the outside of the connector 13, the fixed frame 311 penetrating a third fixed plate 15, the third fixed plate 15 having an annular groove, the fixed frame 311 being located within the annular groove, the upper end of the fixed frame 311 being provided with a threaded rod 310, the external thread of the threaded rod 310 being threadedly connected to a second fixed plate 14, the second fixed plate 14 being mounted between two support plates 2, and the upper end of the threaded rod 310 penetrating the second fixed plate 14 being provided with a rotating block 39;

[0030] The opening and closing mechanism 3 also includes the output shaft of the motor 38 fixed on the upper end of the rotating block 39. The motor 38 is provided with a fixed frame 31. The motor 38 is a low-speed forward and reverse motor. The upper end of the fixed frame 31 is provided with a movable column 33. A spring 37 is sleeved on the outside of the movable column 33. One end of the spring 37 is connected to the upper end of the fixed frame 31, and the other end is connected to the first sleeve 32. The movable column 33 extends into the interior of the first sleeve 32. The upper end of the first sleeve 32 is provided with a first fixing plate 4. The first fixing plate 4 is fixed on the upper end of the support plate 2.

[0031] In this embodiment, to ensure the stability of the lifting and lowering of the fixed frame 31, a movable rod 36 is provided at the upper end of the fixed frame 31, and a second sleeve 34 is provided outside the movable rod 36. A limit block 35 is provided at one end of the movable rod 36 that extends into the interior of the second sleeve 34. The limit block 35 is slidably connected to the second sleeve 34. Two sets of movable column 33, spring 37 and first sleeve 32 are provided and respectively provided on both sides of the upper end of the fixed frame 31 to provide stable load-bearing capacity.

[0032] Specifically, once the connector 13 is aligned with the gas cylinder port, the motor 38 is turned on. The motor 38 drives the rotating block 39 to rotate. As the rotating block 39 rotates, it drives the threaded rod 310 to rotate and descend, thereby driving the fixed frame 311 to rotate and descend. This causes the connector 13 to rotate automatically. The fixed frame 31 outside the motor 38 is provided with load-bearing force by the spring 37. When the rotating block 39 descends, it drives the motor 38 and the fixed frame 31 to descend. The connector 13 is automatically fixed to the gas cylinder port without the need for manual rotation and fixing, thus saving time and improving removal efficiency.

[0033] A smart integrated gas cylinder drying and vacuuming method includes the following steps: First, open the first chamber 1, and place multiple sets of gas cylinders sequentially into the bottom of the second chamber 9, positioned in the second semi-circular groove 11. Then, close the first chamber 1, causing the first semi-circular groove 10 of the first chamber 1 to engage with the outside of the gas cylinder, thus fixing the gas cylinder by the engagement of the second semi-circular groove 11 and the first semi-circular groove 10. After fixing, align the connector 13 with the gas cylinder port, and turn on the motor 38. The motor 38 drives the rotating block 39 to rotate, and the rotation of the rotating block 39 drives the threaded rod 3... 10 rotates and descends, thereby driving the fixed frame 311 to rotate and descend, thus causing the connector 13 to rotate automatically. The fixed frame 31 outside the motor 38 is supported by the spring 37. When the rotating block 39 descends, it drives the motor 38 and the fixed frame 31 to descend. After the fixing is completed, the vacuum pump 5 is turned on to draw a vacuum through the hose 6, hard pipe 12 and connector 13, and the external electric heating tube 8 heats and dries the gas cylinder. The water inside the gas cylinder is heated and evaporated to form water vapor, so that the vacuum pump 5 not only draws out the water vapor, but also draws out the impurities inside.

[0034] The solution in this embodiment can be selectively combined with solutions in other embodiments.
