Description

Technical Field

[0001] This utility model belongs to the field of medical oxygen generator technology, and in particular relates to a medical oxygen generator that is easy to replace molecular sieves. Background Technology

[0002] Medical oxygen concentrators are devices that separate and purify oxygen from the air to a medical-grade concentration (≥90%) through physical adsorption (such as molecular sieve technology). They are widely used in medical institutions or home settings to provide patients with stable and high-purity oxygen support. In traditional medical oxygen concentrators, molecular sieves are the core consumables and need to be replaced regularly to maintain oxygen production efficiency.

[0003] Molecular sieves are usually encapsulated inside molecular sieve towers. Replacing them requires disassembling the entire molecular sieve tower and related pipelines, which is cumbersome and requires professional personnel, resulting in prolonged downtime and affecting the continuity of equipment use. Traditional filling methods rely on manual operation, and the molecular sieves are prone to uneven distribution or insufficient density in the tower, affecting adsorption efficiency. To address these issues, we provide a medical oxygen generator that facilitates molecular sieve replacement. Utility Model Content

By combining supplementary and compact components, it solves the problem in existing medical oxygen generators where the entire molecular sieve tower and related pipelines need to be disassembled for replacement, which is cumbersome, requires professional personnel, and leads to prolonged downtime and affects the continuity of equipment use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a medical oxygen generator with an easily replaceable molecular sieve. It includes a housing, inside which a molecular sieve tower is housed.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figures 1-5 This utility model relates to a medical oxygen generator with an easy-to-replace molecular sieve. It includes a housing 1, a molecular sieve tower 2 inside the housing 1, a filter box 3 connected to the front of the molecular sieve tower 2, a humidification bottle 4 placed on top of the housing 1, a control panel 5 on the front of the housing 1, and a replenishment assembly on the rear of the housing 1. The replenishment assembly includes a replenishment box 6 located on the rear of the housing 1, a drive motor 7 inside the replenishment box 6, an auger 8 fixedly connected to the output end of the drive motor 7, and a replenishment pipe 9 connected to the bottom of the replenishment box 6. Through the replenishment assembly, the molecular sieve can be replenished online without disassembling the molecular sieve tower 2, significantly reducing downtime. A compaction assembly is provided on the rear side of the molecular sieve tower 2. The compaction assembly includes a vibrating plate 10 fixedly connected to the rear side of the molecular sieve tower 2, a vibrating motor 11 fixedly connected to the rear side of the vibrating plate 10, an extension plate 12 fixedly connected to one side of the vibrating plate 10, a spring 13 fixedly connected to the bottom of the extension plate 12, a support plate 14 fixedly connected to the bottom of the spring 13, a mounting plate 15 fixedly connected to one side of the support plate 14, and an electromagnet 16 fixedly connected to one side of the mounting plate 15. Through the setting of the compaction assembly, the vibrating motor 11 drives the vibrating plate 10 to generate high-frequency vibration, so that the molecular sieve is evenly distributed and compacted in the molecular sieve tower 2, thereby improving the adsorption efficiency.

[0027] Example 2

[0028] Please see Figures 1-5Based on Embodiment 1, a support frame is fixedly connected to the rear side of the outer shell 1, and the replenishment box 6 is located inside the support frame. A feeding pipe 17 is connected to the top of the replenishment box 6. The support frame is used to place the replenishment box 6 on the rear side of the outer shell 1, and the feeding pipe 17 is used to replenish the molecular sieve. A protective box 18 is fixedly connected inside the replenishment box 6. The protective box 18 is located outside the drive motor 7. The end of the auger 8 away from the drive motor 7 is movably connected to the replenishment box 6 through a bearing. The protective box 18 protects the drive motor 7. Inside the outer casing 1 is a collection box 19. A limiting plate 20 is fixedly connected to one side of the outer casing 1. A limiting groove is formed inside the limiting plate 20, and a baffle 21 is slidably connected inside the limiting groove. A pull-out channel adapted to the collection box 19 is formed on one side of the outer casing 1. The collection box 19 is used to collect the replaced molecular sieves. The baffle 21 is used to block the pull-out channel. The molecular sieve tower 2 is fixedly connected to one side of the vibrating plate 10 by bolts. The bottom of the molecular sieve tower 2 is connected to a discharge pipe 22. The replenishment pipe 9 is away from the replenishment box 6. One end is connected to the molecular sieve tower 2. Both the discharge pipe 22 and the replenishment pipe 9 are connected to self-regulating valves 23. Solid flow sensors are fixedly connected inside both the discharge pipe 22 and the replenishment pipe 9. These solid flow sensors detect the amount of molecular sieve entering and exiting. Through the configuration of the discharge pipe 22 and the self-regulating valves 23, when it is necessary to replace the molecular sieve inside the molecular sieve tower 2, the self-regulating valves 23 are opened, allowing the molecular sieve to fall downwards through the discharge pipe 22 into the collection box 19. A damper 24 is fixedly connected inside the spring 13. The top of the damper 24 is connected to the extension plate 12. The bottom is fixedly connected to the damper 24 and the top of the support plate 14. The damper 24 is used to counteract the excessive vibration of the vibration motor 11 and prevent the vibration from being transmitted to the external structure. The electromagnet 16 and the extension plate 12 are magnetically attracted. The extension plate 12 is made of magnetically conductive material. There are four extension plates 12, four springs 13 and four support plates 14. The magnetically attracted extension plates 12 are used to fix the vibration plate 10 by magnetic attraction after the molecular sieve is replaced, so as to prevent the vibration plate 10 from continuing to shake during use.

[0029] The working principle of this utility model is as follows: the molecular sieve in the molecular sieve tower 2 is replaced periodically and quantitatively. When replacement is required, the self-control valve 23 on the surface of the discharge pipe 22 is activated, and the electromagnet 16 is closed at the same time, so that the electromagnet 16 and the extension plate 12 lose magnetic attraction and fixation. The vibration motor 11 is activated, and the vibration motor 11 drives the vibration plate 10 to vibrate. The vibration plate 10 drives the molecular sieve tower 2 to vibrate, so that the molecular sieve inside the molecular sieve tower 2 falls into the collection box 19 through the discharge pipe 22. After the molecular sieve is discharged, the self-control valve 23 on the surface of the discharge pipe 22 is closed.

[0030] Then, the self-control valve 23 on the surface of the replenishment pipe 9 and the drive motor 7 are turned on. The drive motor 7 drives the auger 8 to rotate. The auger 8 pushes the molecular sieve in the replenishment box 6 to the replenishment pipe 9, and flows into the molecular sieve tower 2 through the replenishment pipe 9. The vibration motor 11 drives the vibration plate 10 to vibrate up and down. The molecular sieve inside the molecular sieve tower 2 is compacted under the action of vibration. When the molecular sieve is added, the drive motor 7 and the vibration motor 11 are turned off, and the electromagnet 16 is energized so that the electromagnet 16 magnetically attracts the extension plate 12 and fixes the vibration plate 10. At this time, the molecular sieve in the molecular sieve tower 2 is replaced.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
