[0019] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0020] Please see Figures 1-5 In this embodiment, a high-efficiency oxygen filling machine includes a base 1 and a top plate 4. The top of the base 1 is adjacent to the bottom of the top plate 4. Control structures 2 are respectively connected to the left and right sides of the top of the top plate 4. An oxygen filling pump 5 is fixed to the rear end face of the base 1. The model of the oxygen filling pump 5 is selected according to the usage requirements. A power structure 3 is connected to the front of the base 1. A slider 10 is fixed to the bottom of the top plate 4. The bottom of the outer wall of the slider 10 is slidably connected to the bottom groove of the inner wall of the base 1. The slider 10 slides left and right through the bottom groove of the inner wall of the base 1 when subjected to force.

[0021] Control structure 2 includes a housing 201 and a straight rod 202. The bottom of the housing 201 is fixedly connected to the top of the top plate 4. The circular opening on the front of the housing 201 is slidably connected to the outer wall of the straight rod 202. The straight rod 202 slides back and forth through the circular opening on the front of the housing 201 under force. A circular plate 203 is fixedly connected to the front of the straight rod 202. A spring 204 is sleeved on the outer wall of the straight rod 202. The two ends of the spring 204 are fixedly connected to the front of the housing 201 and the rear end face of the circular plate 203, respectively. After the circular plate 203 moves forward under force, it slides back and forth through the circular opening. The spring 204 rebounds due to its elasticity. The rear end face of the straight rod 202 is fixedly connected to the first clamping plate 205. The rear of the inner wall of the outer shell 201 is fixedly connected to the second clamping plate 206. Both the first clamping plate 205 and the second clamping plate 206 are made of rubber. The rear end face of the first clamping plate 205 is in contact with the front face of the second clamping plate 206. The bottom of the inner wall of the outer shell 201 is fixedly connected to the inclined block 8. The lower part of the inner wall of the outer shell 201 is fixedly connected to the mesh plate 9. The lower part of the front face of the outer shell 201 is connected to the valve 6. The model of the valve 6 is selected according to the usage requirements.

[0022] By controlling the circular plate 203 in structure 2 to move forward along the straight rod 202, the moving straight rod 202 moves forward along the inner wall of the outer casing 201 along with the first clamping plate 205. At the same time, the circular plate 203 stretches the spring 204. Then, the bottle is placed on top of the outer casing 201, so that the outer wall of the bottle fits against the groove on the outer wall of the second clamping plate 206. Then, the circular plate 203 is released, and the spring 204 provides a restoring force, causing the circular plate 203 to move backward along with the straight rod 202. The moving straight rod 202 moves backward along with the first clamping plate 205, so that the first clamping plate 205 presses the bottle against the second clamping plate 206, ensuring the stability of the bottle, preventing collisions, reducing the danger of using the oxygen filling machine, and eliminating the limitations of using the oxygen filling machine.

[0023] The power structure 3 includes a motor 301 and a gear 302. The outer wall of the motor 301 is fixedly connected to the front of the base 1. The motor 301 is a servo motor model selected according to the usage requirements. The output shaft of the motor 301 is fixedly connected to the front of the gear 302. The outer wall of the gear 302 is meshed with a toothed plate 303. The top of the toothed plate 303 is fixedly connected to the bottom of the top plate 4.

[0024] Working principle:

[0025] Oxygen filling machine cylinder clamping:

[0026] The circular plate 203 moves forward along with the straight rod 202. The moving straight rod 202 moves forward along with the first clamping plate 205 on the inner wall of the outer shell 201. At the same time, the circular plate 203 stretches the spring 204. Then, the bottle is placed on top of the outer shell 201, so that the outer wall of the bottle fits against the groove on the outer wall of the second clamping plate 206. Then, the circular plate 203 is released, and the spring 204 provides a restoring force, causing the circular plate 203 to move backward along with the straight rod 202. The moving straight rod 202 moves backward along with the first clamping plate 205, so that the first clamping plate 205 presses the bottle against the second clamping plate 206.

[0027] Oxygen filling machine oxygenation operation:

[0028] When motor 301 is powered on, its output shaft drives gear 302 to rotate. The rotating gear 302 causes gear plate 303 to move to the left, which in turn moves top plate 4 to the left. This causes the outer casing 201 on the right side of top plate 4 to move below the air inlet of oxygen filling pump 5. Then, oxygen filling pump 5 moves its air inlet downward, inserting the air inlet into the valve at the top of the bottle. The valve opens under pressure, and oxygen filling pump 5 delivers oxygen into the bottle. The air inlet then lifts upward and detaches from the bottle, causing the valve to close under pressure. Motor 301 then reverses its operation, placing the bottle inside the left outer casing 201 below the air inlet. At this point, the right outer casing 201 returns to its original position, enabling continuous operation, shortening the working interval, and improving work efficiency.

[0029] Oxygen filling pump for cylinder airtightness testing:

[0030] After the right outer casing 201 is returned to its original position, pour water into the right outer casing 201, ensuring the water temperature is between 50 and 55 degrees Celsius, so that the bottle is submerged. Check if bubbles are generated in the water. If bubbles are generated, it indicates that the bottle is leaking. If no bubbles are generated, open valve 6 to drain the water inside the outer casing 201. Then, disassemble the bottle by performing the above-mentioned control structure 2 operation, and then dry the bottle. Example 2

[0031] Please see Figures 1-5In this embodiment, a high-efficiency oxygen filling machine also includes a wheel 7. The inner walls of multiple wheels 7 are rotatably connected to the front and rear slots of the top plate 4, and the bottom of the wheel 7 is in contact with the top of the base 1.

[0032] Working principle:

[0033] When the top plate 4 moves left and right, it moves the wheel 7 left and right as well. At the same time, the outer wall of the wheel 7 rotates with friction against the top of the base 1. The wheel 7 supports the top plate 4.
