Description

Technical Field

[0001] This utility model relates to the field of oxygen generator technology, and in particular to an oxygen generator with a shock-absorbing structure. Background Technology

[0002] An oxygen concentrator is a common medical device that uses air separation technology to produce oxygen. It is widely used in homes, hospitals, and nursing homes to provide high concentrations of oxygen to meet the respiratory needs of patients.

[0003] However, in actual use, the compressor, fan and other components inside the oxygen concentrator will generate a certain amount of vibration during operation. In addition, during transportation, placement or use, the oxygen concentrator may also be subjected to external impacts, such as collisions or drops. These vibrations and impacts not only affect the operational stability of the oxygen concentrator, but may also damage internal precision components, reducing the service life and reliability of the oxygen concentrator. Traditional oxygen concentrators mostly rely on simple cushioning measures such as simple rubber pads to cope with vibrations and impacts. However, these measures are often difficult to effectively absorb and disperse large impact forces, and are difficult to meet the stability and reliability requirements of oxygen concentrators in complex usage environments. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an oxygen generator with a shock-absorbing structure.

[0005] This utility model is achieved using the following technical solution: an oxygen generator with a shock-absorbing structure, comprising an oxygen generator body, an mounting plate fixedly connected to the lower surface of the oxygen generator body, support columns fixedly connected to the four corners of the lower surface of the mounting plate, a vertical spring fixedly connected to the bottom end of the support column, a reinforcing sleeve fixedly connected to the bottom end of the vertical spring, a shock-absorbing mechanism fixedly connected to the lower surface of the mounting plate, upper frame plates fixedly connected to both sides of the outer surface of the oxygen generator body, a force-relieving roller rotatably connected to the lower surface of the upper frame plate, and a lower frame plate rotatably connected to the bottom end of the force-relieving roller.

[0006] The shock absorption mechanism includes a movable seat one and a positioning plate. A connecting rod is rotatably connected inside the movable seat one, and a movable seat two is rotatably connected to the surface of the connecting rod. A guide groove is formed on the surface of the positioning plate, and a transverse spring is fixedly connected to the inner wall of the guide groove.

[0007] Through the above technical solution, the vertical spring and shock absorption mechanism work together to effectively buffer the vertical impact force, reduce the vibration of the oxygen concentrator in the vertical direction, protect the precision components inside the oxygen concentrator, and extend its service life. The design of the unloading roller can buffer the side impact force, avoid damage to the side of the oxygen concentrator from direct impact, improve the overall stability and reliability of the oxygen concentrator, and enable it to maintain a good working condition in various complex operating environments.

[0008] As a further improvement to the above solution, damping rods are fixedly installed inside both the reinforcing sleeve and the guide groove.

[0009] Through the above technical solutions, the damping rod can effectively improve the vibration reduction performance of the vibration reduction mechanism, making the vibration reduction process more stable and reliable, further reducing the vibration experienced by the oxygen concentrator, and better protecting the internal components of the oxygen concentrator.

[0010] As a further improvement to the above solution, the first movable seat is fixedly connected to the lower surface of the mounting plate, and the second movable seat is slidably connected to the inside of the guide groove.

[0011] As a further improvement to the above solution, a base plate is fixedly connected to the bottom end of the reinforcing sleeve.

[0012] As a further improvement to the above solution, the positioning plate is fixedly connected to the upper surface of the base plate.

[0013] As a further improvement to the above solution, the second movable seat is in contact with the transverse spring.

[0014] Through the above technical solution, the contact between the movable seat 2 and the transverse spring can ensure that the transverse spring can effectively buffer the movement of the movable seat 2.

[0015] As a further improvement to the above solution, a rubber pad is fixedly connected to the surface of the oxygen generator body.

[0016] The above technical solution can further improve the vibration damping performance of the oxygen generator by setting up the rubber pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes the elastic deformation of a vertical spring to initially buffer vertical vibrations. Simultaneously, the movement of movable seat one and connecting rod in the shock absorption mechanism pushes movable seat two to slide within the guide groove, compressing the transverse spring and further buffering the vertical impact force. The damping rod dampens and limits the extension and retraction of the vertical spring and the sliding speed of movable seat two, making the shock absorption process smoother and preventing excessive rebound force or vibration caused by excessive spring extension or rapid sliding of the movable seat. The unloading roller can change the direction of the lateral impact force, dispersing it and reducing the direct effect of lateral impact on the oxygen concentrator body. This effectively protects the precision components inside the oxygen concentrator, preventing damage from vibration and impact, and extending the service life of the oxygen concentrator.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4An oxygen generator with a shock-absorbing structure according to this embodiment includes an oxygen generator body 1. An installation plate 2 is fixedly connected to the lower surface of the oxygen generator body 1. Support columns 3 are fixedly connected to the four corners of the lower surface of the installation plate 2. Vertical springs 4 are fixedly connected to the bottom of the support columns 3. Reinforcing sleeves 5 are fixedly connected to the bottom of the vertical springs 4. A shock-absorbing mechanism 6 is fixedly connected to the lower surface of the installation plate 2. Upper frame plates 8 are fixedly connected to both sides of the outer surface of the oxygen generator body 1. Unloading rollers 9 are rotatably connected to the lower surface of the upper frame plates 8. Lower frame plates 10 are rotatably connected to the bottom of the unloading rollers 9.

[0028] The shock absorption mechanism 6 includes a movable seat 601 and a positioning plate 604. A connecting rod 602 is rotatably connected inside the movable seat 601, and a movable seat 603 is rotatably connected to the surface of the connecting rod 602. A guide groove 605 is formed on the surface of the positioning plate 604, and a transverse spring 606 is fixedly connected to the inner wall of the guide groove 605. When the oxygen concentrator is subjected to a vertical impact force, the vertical spring 606 will first undergo elastic deformation, providing initial cushioning. Simultaneously, the movable seat 601 in the shock absorption mechanism 6 will drive the connecting rod 602 to move, and the connecting rod 602 will then push the movable seat 603 to slide within the guide groove 605. During this process, the transverse spring 606 will also undergo elastic deformation, further cushioning the vertical impact force. When the oxygen concentrator is subjected to a lateral impact force, the unloading roller 9 will change the direction of the impact force, dispersing it along the rotation direction of the unloading roller 9, thereby providing cushioning and shock absorption to the side of the oxygen concentrator.

[0029] Damping rods are fixedly installed inside both the reinforcing sleeve 5 and the guide groove 605. When the shock absorption mechanism 6 is working, the movable seat 603 slides within the guide groove 605. The damping rods generate damping force, limiting the sliding speed of the movable seat 603, thereby slowing down its movement and further improving the shock absorption effect. At the same time, the damping rods inside the reinforcing sleeve 5 also provide some damping for the extension and retraction of the vertical spring 4, making the buffering process of the vertical spring 4 smoother and preventing excessive rebound force caused by excessive extension and retraction of the spring.

[0030] Movable seat 1 601 is fixedly connected to the lower surface of mounting plate 2, and movable seat 2 603 is slidably connected to the inside of guide groove 605. When the oxygen generator is subjected to impact force, movable seat 1 601 can transmit the impact force to connecting rod 602, and through connecting rod 602, movable seat 2 603 can slide in guide groove 605, thereby realizing the buffering of impact force by shock absorption mechanism 6. Movable seat 2 603 is slidably connected to the inside of guide groove 605, and guide groove 605 provides guidance for the sliding of movable seat 2 603, ensuring that movable seat 2 603 can slide smoothly in a predetermined direction.

[0031] The bottom end of the reinforcing sleeve 5 is fixedly connected to a base plate 7.

[0032] The positioning plate 604 is fixedly connected to the upper surface of the base plate 7. When the movable seat 603 slides in the guide groove 605, the positioning plate 604 can remain stable, providing stable support for the sliding of the movable seat 603 and ensuring that the shock absorption mechanism 6 can work normally.

[0033] The movable seat 603 is in contact with the transverse spring 606. When the movable seat 603 slides in the guide groove 605, it will squeeze or stretch the transverse spring 606, causing the transverse spring 606 to undergo elastic deformation, thereby generating a reverse elastic force, which plays a buffering role on the movement of the movable seat 603 and realizes the buffering and shock absorption of the vertical impact force.

[0034] A rubber pad 11 is fixedly connected to the surface of the oxygen generator body 1. When the front of the oxygen generator is subjected to an impact force, the rubber pad 11 can play a buffering role and reduce the direct impact of the impact force on the surface of the oxygen generator body 1.

[0035] The implementation principle of an oxygen concentrator with a shock-absorbing structure in this embodiment is as follows: When the oxygen concentrator body 1 is started and running, its internal compressor, fan, and other components will generate a certain vibration. This vibration will be transmitted to the mounting plate 2 through the oxygen concentrator body 1. At this time, the vertical spring 4 will first undergo elastic deformation to initially buffer the vertical vibration. Simultaneously, the movable seat 601 in the shock-absorbing mechanism 6 will be affected by the vibration and drive the connecting rod 602 to move. The movement of the connecting rod 602 further pushes the movable seat 603 to slide in the guide groove 605. The transverse spring 606 in the guide groove 605 will undergo elastic deformation under the compression or stretching of the movable seat 603, generating a reverse spring. The damping rod inside the reinforcing sleeve 5 dampens the vertical impact force, thereby further buffering the vertical impact force. In addition, the damping rod inside the reinforcing sleeve 5 dampens the extension and retraction of the vertical spring 4 and the sliding speed of the movable seat 603, making the shock absorption process smoother and avoiding excessive vibration or rebound. If the oxygen generator 1 is subjected to a side impact force during operation, such as accidentally colliding with the side during handling or use, the unloading roller 9 can change the direction of the side impact force, dispersing it along the rotation direction of the roller, thereby reducing the direct effect of the side impact force on the oxygen generator 1. At the same time, the rubber pad 11 on the surface of the oxygen generator 1 will also play a buffering role when subjected to impact, reducing the direct impact of the impact force on the surface of the oxygen generator 1.

[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
