The whole operation process is relatively complicated, which is not convenient for patients who are obviously weak or elderly patients. It is difficult for them to complete all operations quickly, and there are certain safety hazards. Utility Model Content

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] Example:

[0031] like Figures 1-6 The embodiment of the present utility model provides a portable oxygen supply cylinder, comprising a bottle body 1 for storing compressed oxygen, and further comprising: a downwardly concave top cover 2, fixedly connected to the upper end of the bottle body 1, and integrally formed with the bottle body 1;

[0032] The top cover 2 has a mounting hole 3 on its interior, and a gas valve 4 is fixedly mounted in the mounting hole 3. When the gas valve 4 is pressed downward, oxygen is discharged from the top of the gas valve 4. The gas valve 4 may be a push-type release valve.

[0033] Two symmetrically arranged rotating rods 5 are respectively rotatably connected to the upper ends of the top cover 2. An upwardly arched end cover 6 is fixedly installed between the two rotating rods 5. The top of the end cover 6 is provided with an air hole 7 aligned with the air valve 4. A pressing portion for pressing the air valve 4 is provided inside the end cover 6. The cross-sectional shapes of the top cover 2 and the end cover 6 are both semicircular, and the diameter of the end cover 6 is smaller than the diameter of the top cover 2. A cavity similar to a spherical shape is formed between the end cover 6 and the top cover 2. The top of the end cover 6 is also fixedly connected with an anti-slip strip 15 for anti-slip.

[0034] Specifically, when in use, push the end cover 6 and rotate it 180° through the rotating rod 5 until the end cover 6 is completely received in the top groove of the top cover 2, that is, the ports of the two are completely flush. At this time, the air hole 7 will be close to the air valve 4, and then the port of the end cover 6 will be buckled at the mouth and nose, and the pressing part will be pressed. At this time, the pressing part will press the air valve 4, and the air valve 4 will discharge oxygen into the end cover 6 through the air hole 7. At this time, the oxygen in the end cover 6 can be absorbed. The whole operation process is simpler and faster, more convenient and efficient to use, and reduces safety hazards.

[0035] The top pressure part in the portable oxygen supply oxygen cylinder includes a short tube 8 that is slidably connected to the air hole 7. The axis of the short tube 8 is collinear with the axis of the air hole 7. One end of the short tube 8 is fixedly connected to a limiting plate 9. A spring 12 is installed between the limiting plate 9 and the inner top of the end cover 6. A support part connected to the limiting plate 9 is provided at the port of the end cover 6.

[0036] Specifically, after rotating the end cover 6, the end cover 6 will drive the short tube 8 toward the upper end of the air valve 4. Therefore, when in use, by applying pressure to the bottle body 1 toward the patient's face, the support part will press the limit plate 9 under the reaction force, and the limit plate 9 will drive the short tube 8 to move toward the upper end of the air valve 4, and the air valve 4 will be pressed by the short tube 8, so that the air valve 4 can be quickly opened without manually pressing the air valve 4, and the operation is more convenient.

[0037] The above-mentioned support part includes an arc rod 11 fixedly connected to the limit plate 9, and a support block 10 extending out of the port of the end cover 6 is fixedly connected to the arc rod 11. The support block 10 has a circular ring shape and is tightly attached to the inner wall of the port of the end cover 6. The support block 10 needs to be made of a soft material, such as medical silicone.

[0038] Specifically, when the end cap 6 is buckled on the mouth and nose, the annular support block 10 will first rest against the face. At this time, pressure is applied to the bottle body 1 toward the face. The support block 10 will be retracted into the end cap 6 under the action of the top pressure, and the limit plate 9 will be driven to slide through the arc rod 11. The limit plate 9 can drive the short tube 8 to slide, and the short tube 8 will eventually complete the action of pressing the air valve 4.

[0039] A sealing block 13 is inserted into the upper end of the air hole 7, and the sealing block 13 is fixedly connected to the bottle body 1 through a connecting rod 14. The connecting rod 14 is elastic. When the sealing block 13 is not inserted into the air hole 7, the movable end of the connecting rod 14 will tilt away from the bottle body 1.

[0040] Specifically, before use, the sealing block 13 inserted in the air hole 7 can prevent foreign matter from entering the end cover 6 and the top cover 2, thereby improving safety. When it is needed, the end cover 6 is rotated. When the pushing force is greater than the resistance given to the air hole 7 by the sealing block 13, the sealing block 13 will automatically pop out from the air hole 7 and drive the sealing block 13 to tilt in the direction away from the bottle body 1, thereby automatically completing the rapid opening action of the sealing block 13. Of course, the sealing block 13 can also be manually picked out. In practice, in order to reduce the volume of the sealing block 13, the sealing block 13 needs to reduce the height of the protruding air hole 7, which is not convenient for manually picking out the sealing block 13.

[0041] The outer wall of the end cap 6 is fixedly connected with a pull ring 16 , which is in close contact with the outer wall of the bottle body 1 . The pull ring 16 and the connecting rod 14 are respectively located on both sides of the end cap 6 .

[0042] Due to the setting of the sealing block 13, the resistance to pushing the end cover 6 will increase. At this time, by pulling one side of the end cover 6 through the pull ring 16, the end cover 6 can be opened more labor-savingly, thereby improving the portability of opening the end cover 6.

[0043] A rubber ring 17 is fixedly connected to the inner wall of the upper port of the above-mentioned top cover 2, and the inner wall of the rubber ring 17 is tightly attached to the outer wall of the lower port of the end cover 6. Before opening the end cover 6, the rubber ring 17 can improve the sealing of the end cover 6 and at the same time increase the resistance between the end cover 6 and the inner wall of the top cover 2 to prevent the end cover 6 from accidentally opening automatically.

[0044] A torsion spring is installed between the rotating rod 5 and the inner wall of the top cover 2 , and the elastic force of the torsion spring is smaller than the resistance given to the end cover 6 by the sealing block 13 .

[0045] Specifically, when the end cover 6 needs to be opened, that is, when the sealing block 13 is disengaged from the air hole 7, the torsion spring will automatically drive the rotating rod 5 to rotate, thereby driving the end cover 6 to rotate automatically, so as to improve the efficiency of opening the end cover 6. Before opening, the resistance of the sealing block 13 will be greater than the elastic force of the torsion spring. When opening, the torsion spring can offset part of the resistance of the sealing block 13.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
