[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0024] Reference Figures 1-7A portable oxygen cylinder flow regulating device includes an oxygen cylinder body 1. A fixing block 2 is fixedly connected to the outer wall of the oxygen cylinder body 1. A motor 3 is fixedly connected to the outer wall of the fixing block 2. The fixing block 2, fixed to the outer wall of the oxygen cylinder body 1, supports and fixes the motor 3. A drive shaft 4 is fixedly installed at the output end of the motor 3. The outer wall of the drive shaft 4 is rotatably connected to the inside of the fixing block 2. A disc 5 is fixedly connected to the outer wall of the drive shaft 4, which fixes the disc 5. A fixing shaft 6 is fixedly connected to the outer wall of the disc 5. A rotating plate 7 is provided on the outer wall of the fixing shaft 6. One end of a sliding rod 8 is fixedly connected to the outer wall of plate 7, and the other end of the sliding rod 8 is fixedly connected to a sealing column 9. A fixing cylinder 10 is slidably connected to the outer wall of the sealing column 9. The outer wall of the fixing cylinder 10 is fixedly connected to the inside of the fixing block 2. The fixing block 2 fixes the fixing cylinder 10. The outer wall of the fixing cylinder 10 is fixedly connected to the inside of the oxygen cylinder body 1. The oxygen cylinder body 1 fixes the fixing cylinder 10. A first one-way valve 11 is installed inside the fixing cylinder 10. A second one-way valve 12 is installed inside the fixing cylinder 10. An oxygen delivery assembly 13 is installed inside the fixing cylinder 10.
[0025] The usage process of the portable oxygen cylinder flow regulating device provided by this utility model is as follows: When oxygen needs to be extracted, the starter motor 3 drives the drive shaft 4 to rotate inside the fixed block 2. During the rotation of the drive shaft 4, the disc 5 rotates simultaneously, which in turn drives the fixed shaft 6 to rotate. The fixed shaft 6 is located on the inner wall of the rotating plate 7. When the fixed shaft 6 rotates, it rotates and slides on the inner wall of the rotating plate 7, applying a pushing force to the rotating plate 7, causing it to slide back and forth with the fixed shaft 6. The rotating plate 7 fixes the sliding rod 8, causing it to slide accordingly. The sliding rod 8 fixes the sealing column 9, which slides against the inner wall of the fixed cylinder 10. The end of the sealing column 9 away from the sliding rod 8 has an arc-shaped design. In its initial position, it is inside one side of the fixed cylinder 10, forming a seal through the fitting design. A stop is provided inside the side of the fixed cylinder 10 away from the sliding rod 8. During the sliding process, it will fit tightly against its inner wall. The inside of the baffle has a channel that allows oxygen to flow. By adjusting the position of the baffle inside the fixed cylinder 10 with the sealing column 9, the inner diameter of the oxygen flow channel can be adjusted. The oxygen inside the oxygen cylinder body 1 enters the inside of the fixed cylinder 10 through the first one-way valve 11 and is delivered to the inside of the oxygen delivery assembly 13 through the second one-way valve 12. The first one-way valve 11 and the second one-way valve 12 ensure that the oxygen flows in one direction and cannot flow in the opposite direction, effectively preventing the oxygen from flowing back into the oxygen cylinder body 1 due to pressure changes during delivery. By adjusting the position of the sealing column 9, the size of the oxygen channel can be adjusted to achieve precise control of the oxygen flow rate and ensure that the oxygen flows in one direction during delivery, preventing gas backflow. At the same time, the oxygen cylinder body 1 and the various components set on it are designed to be relatively concentrated, small in size, and easy to carry.
[0026] Reference Figure 5 and Figure 6 The oxygen delivery assembly 13 includes a connecting column 1301, the outer wall of which is slidably connected to the inside of the fixed cylinder 10. An oxygen inhalation tube 1302 is fixedly connected inside the connecting column 1301, and the connecting column 1301 serves to fix the oxygen inhalation tube 1302. A sealing plug 1303 is fixedly connected to the bottom of the connecting column 1301, and the outer wall of the sealing plug 1303 is slidably connected to the inner wall of the second one-way valve 12.
[0027] The usage process of the portable oxygen cylinder flow regulating device provided by this utility model is as follows: Slide the connecting column 1301 and the sealing plug 1303 into the interior of the fixed cylinder 10. The sealing plug 1303 will fit tightly against the inner wall of the second one-way valve 12 to form a seal, preventing leakage during oxygen inhalation. Oxygen will enter the interior of the oxygen inhalation tube 1302 through the second one-way valve 12, facilitating subsequent oxygen inhalation.
[0028] Reference Figure 5 , Figure 6 and Figure 7A fixed post 14 is fixedly connected inside the fixed cylinder 10, and a button 15 is slidably connected inside the fixed post 14. The fixed post 14 is fixed inside the fixed cylinder 10 and supports the button 15. A connecting rod 16 is fixedly connected to the outer wall of the button 15, and the outer wall of the connecting rod 16 is slidably connected to the inside of the fixed post 14 and the inside of the fixed cylinder 10. A first spring 17 is slidably connected to the outer wall of the connecting rod 16, one end of the first spring 17 is fixedly connected to the inside of the fixed post 14, and the other end of the first spring 17 is fixedly connected to the outer wall of the button 15. A push rod is fixedly connected to the outer wall of the connecting rod 16. The push plate 18 and the connecting rod 16 fix the push plate 18. The outer wall of the push plate 18 is slidably connected to the inside of the fixed cylinder 10. A ball 19 is slidably connected to the outer wall of the push plate 18. The outer wall of the ball 19 is slidably connected to the inside of the fixed cylinder 10 and the connecting column 1301. A connecting piece 20 is fixedly connected to the outer wall of the ball 19, and the ball 19 fixes the connecting piece 20. The outer wall of the connecting piece 20 is slidably connected to the inside of the connecting column 1301, and a second spring 21 is fixedly connected to the outer wall of the connecting piece 20. The outer wall of the second spring 21 is fixedly connected to the inside of the connecting column 1301.
[0029] The usage process of the portable oxygen cylinder flow regulating device provided by this utility model is as follows: When the oxygen tubing 1302 needs to be installed and used, the connecting post 1301 is slid into the fixing cylinder 10. During the sliding process, the inner wall of the fixing cylinder 10 will squeeze the ball bearings 19 on both sides, causing the connecting piece 20 to slide on the inner wall of the connecting post 1301. The second spring 21 is located between the connecting piece 20 and the connecting post 1301. The second spring 21 will be squeezed due to the sliding of the connecting piece 20. When the ball bearing 19 slides to the groove corresponding to the push piece 18, the rebound action of the second spring 21 will push the connecting piece 20 and the ball bearing 19 to slide in the opposite direction, so that the ball bearing 19 is stuck inside the fixing cylinder 10, thereby fixing the connecting post 1301 and the oxygen tubing 1302 for use. When not in use, the connecting post 1301 and the oxygen tubing 1302 are removed, and the buttons 15 on both sides are pushed to slide inside the fixing post 14. During the sliding process, the connecting rod 16 will be pushed to slide. The first spring 17 is set between the button 15 and the fixed post 14. The first spring 17 will be squeezed by the sliding of the button 15. At the same time, the first spring 17 will play a rebound role. When no force is applied, it will push the button 15 to slide in the opposite direction through its own rebound. During the sliding of the connecting rod 16, the push plate 18 will slide synchronously. When the push plate 18 slides, it will contact the ball 19. Through continuous sliding, the ball 19 will be pushed to slide inside the fixed cylinder 10 and the connecting post 1301. At this time, the oxygen tube 1302 can be pulled upward to remove the connecting post 1301 and the sealing plug 1303 from the inside of the fixed cylinder 10. The oxygen tube 1302 can be installed or removed without complicated tools or operations, which is convenient for quick installation and use or removal for cleaning and disinfection, ensuring the hygiene and safety of the oxygen tube 1302.
