Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, specifically to an oxygen generator with easily adjustable flow rate. Background Technology

[0002] An oxygen concentrator is a type of machine that produces oxygen. It mainly utilizes the adsorption properties of molecular sieves and uses a large-displacement oil-free compressor to separate nitrogen and oxygen in the air through physical principles, ultimately obtaining a high concentration of oxygen. Under normal circumstances, because it is mostly used to produce oxygen, people are used to calling it an oxygen concentrator.

[0003] Currently, existing oxygen concentrators with easily adjustable flow rates typically adjust the oxygen flow rate to suit different patients' oxygen needs. However, because the knobs or levers of the flow adjustment mechanism are exposed during use, accidental activation can easily occur when the concentrator is supplying oxygen to the patient, thus affecting the patient's oxygen flow and causing problems with accidental activation of the adjustment mechanism. Furthermore, existing home oxygen concentrators usually supply oxygen to the user through an external oxygen tube, which is stored separately. When using the concentrator, the oxygen tube must be located and connected first, which is cumbersome and inconvenient. There is also a lack of a structure to house the oxygen tube in the concentrator. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example

[0024] Please see Figures 1 to 5 The present invention provides a technical solution including an oxygen concentrator body 1, a fixing block 3 fixedly connected to one side of the oxygen concentrator body 1, a connector 2 fixedly connected to the upper part of the fixing block 3, a protective sleeve 4 fixedly connected to one side of the fixing block 3, a connecting sleeve 12 connected to the bearing inside the protective sleeve 4, a movable rod 13 slidably connected inside the connecting sleeve 12, a connecting groove 15 opened at one end of the movable rod 13 connected to a connecting block 17, the connecting block 17 connected to a ball valve 16 inside the fixing block 3, a movable plate 7 hinged to the lower part of the oxygen concentrator body 1, a partition plate 11 fixedly connected to one side of the movable plate 7, a baffle 9 fixedly connected to one side of the partition plate 11, and a placement groove 10 formed between the partition plates 11.

[0025] Please see Figures 2 to 3 The fixed block 3 has a transmission pipe inside, the ball valve 16 is located inside the transmission pipe, and the transmission pipe is connected to the connector 2.

[0026] Specifically, connector 2 is a quick-connect connector, and one end of the oxygen tube is equipped with a plug that connects with it.

[0027] Please see Figures 1 to 5 The outer end of the movable rod 13 is fixedly connected to the movable block 5. A pointer is set on the upper part of the movable block 5. A scale is set inside the fixed block 3. A pointer is set on the upper part of the fixed block 3. The scale is connected to one end of the ball valve 16.

[0028] Specifically, the scale indicates the oxygen flow rate adjusted by rotating the ball valve 16.

[0029] Please see Figures 2 to 5 A groove 14 is provided on one side of the movable rod 13. The slider inside the connecting sleeve 12 is slidably connected inside the groove 14. The connecting block 17 fits closely with the connecting groove 15. The shape of the connecting block 17 is rectangular.

[0030] Specifically, the slider inside the connecting sleeve 12 slides in the sliding groove 14, which restricts and guides the movement of the movable rod 13. The connecting groove 15 is fitted on the connecting block 17, so that the movable block 5, the movable rod 13, the connecting block 17 and the ball valve 16 rotate coaxially.

[0031] Please see Figures 1 to 3 A stop bar 6 is slidably connected to one side of the oxygen concentrator body 1. The lower part of the stop bar 6 abuts against the movable plate 7, and a chamfer is provided on the lower outer side of the stop bar 6.

[0032] Specifically, the stop lever 6 is located on the upper part of the movable plate 7, and the lower part of the movable plate 7 is connected to the oxygen generator body 1 through a hinge. A spring with a reset function is provided on one side of the stop lever 6 to support the stop lever 6 downward.

[0033] Please see Figures 1 to 3 A storage tank 8 is provided on one side of the oxygen generator body 1. Inside the storage tank 8, there are baffles 9 and partitions 11. The partitions 11 are arranged in a linear array, and a placement slot 10 is formed between two adjacent partitions 11.

[0034] Specifically, the oxygen tube is placed inside the placement slot 10, the baffle 9 blocks the oxygen tube inside the placement slot 10, and when the movable plate 7 is closed, its inner side is in contact with the oxygen generator body 1.

[0035] In use, the oxygen tubing plug is inserted into the connector 2. The protective sleeve 4 protects the connecting block 17, preventing accidental contact that could directly rotate the connecting block 17, thereby rotating the ball valve 16 and adjusting the oxygen delivery flow. The protective sleeve 4 effectively blocks the valve structure to prevent accidental contact. During adjustment, the movable block 5 is pressed inwards, causing the movable rod 13 to move inwards, allowing the connecting groove 15 to fit onto the connecting block 17. Rotating the movable block 5 then causes the movable rod 13 to rotate around its center. The movable rod 13 slides through the groove 14 and connects to the connecting sleeve 12. The movable rod 13 is limited in movement by the block 5. When the movable rod 13 rotates, it drives the connecting sleeve 12 to rotate inside the protective sleeve 4. This drives the ball valve 16 to rotate through multiple coaxial structures of the movable block 5. When adjusting, it is necessary to press first and then rotate, thereby reducing accidental operation. Through the coordinated arrangement of the movable block 5, movable rod 13, connecting groove 15, connecting block 17, sliding groove 14, protective sleeve 4 and connecting sleeve 12, it can be connected to the valve structure first and then driven during use, thereby preventing accidental adjustment of the flow rate and achieving the purpose of preventing accidental operation of the regulating structure.

[0036] When storing oxygen tubes, a brand-new oxygen tube is placed in the placement slot 10 between the partition plates 11. Then, the baffle 9 restricts one side of the placement slot 10 to limit the oxygen tube's position. Through the arrangement of the baffle 9, movable plate 7, partition plates 11, and placement slot 10, the oxygen tube can be placed. When it is necessary to place or remove the tube, the stop rod 6 is pulled upward, which allows the movable plate 7 to rotate around the lower hinge, exposing the placement slot 10, thereby placing or removing the oxygen tube. After the operation is completed, the movable plate 7 is rotated back into the storage slot 8, and the stop rod 6 is supported downward by the return spring, so that the stop rod 6 blocks the movable plate 7, storing the oxygen tube in the oxygen generator body 1. Through the coordinated arrangement of the stop rod 6, placement slot 10, and movable plate 7, the oxygen tube can be stored during use, thus achieving the purpose of storing the oxygen tube in the oxygen generator.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
