[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides a combined molecular sieve oxygen generator, such as Figure 1-4 As shown, the combined molecular sieve oxygen generator includes an oxygen generator body 1. Four sets of locking casters 2 are fixedly installed on the lower side of the oxygen generator body 1. A humidification cup 3 is movably installed on the upper front side of the oxygen generator body 1. Two sets of connection ports 4 are provided on the upper front side of the oxygen generator body 1. A control button 5 is provided on the upper front side of the oxygen generator body 1. The two sets of connection ports 4 and the control button 5 are symmetrically arranged on the left and right. Two sets of adjustment chambers 7 are opened in the lower end of the oxygen generator body 1. Adjustment components for supporting and limiting the oxygen generator body 1 are provided in the two sets of adjustment chambers 7.
[0024] The oxygen concentrator body 1 is raised by adjusting the rotation of the components, thereby separating the four sets of locking casters 2 at the lower end of the oxygen concentrator body 1 from the ground. This allows the oxygen concentrator body 1 to be moved to a position for use and then fixed in place to prevent displacement of the oxygen concentrator body 1 during use.
[0025] The adjustment assembly includes four sets of sliding grooves 6, which are located inside the oxygen generator body 1 on the upper side of the two sets of adjustment chambers 7. Two bidirectional threaded rods 8 are rotatably installed in each of the two sets of adjustment chambers 7. Both ends of the two sets of bidirectional threaded rods 8 are threadedly connected to sleeve blocks 9. Guide blocks 10 are fixedly installed on the upper ends of the four sets of sleeve blocks 9, and support rods 11 are rotatably installed on the lower ends of the four sets of sleeve blocks 9. Two sets of support pads 12 are installed on the lower ends of the four sets of support rods 11.
[0026] By rotating the two sets of bidirectional threaded rods 8, the four sets of sleeve blocks 9 are driven to slide on the two sets of bidirectional threaded rods 8. The support rods 11 at the lower end of the four sets of sleeve blocks 9 drive the support pads 12 to move up and down, supporting the oxygen generator body 1, thereby lifting the oxygen generator body 1 off the ground, completing the fixation of the oxygen generator body 1, and improving the stability of the overall structure.
[0027] Synchronous pulleys 15 are fixedly installed at the rear ends of both sets of bidirectional threaded rods 8, and synchronous belts 16 are sleeved on the two sets of synchronous pulleys 15. An adjustment knob 17 is fixedly installed at the rear end of the bidirectional threaded rods 8 inside the left end of the oxygen generator body 1.
[0028] The timing pulley 15 and timing belt 16 allow for easy rotation of the two sets of bidirectional threaded rods 8, thereby driving the sleeve block 9 to slide on the bidirectional threaded rods 8, ensuring the normal operation of the adjustment assembly.
[0029] Multiple sets of guide grooves 13 are opened in the oxygen generator body 1 on both sides of the two sets of adjustment chambers 7. Guide rods 14 are movably inserted in the multiple sets of guide grooves 13. The multiple sets of guide rods 14 are fixedly connected to the left and right sides of the two sets of support pads 12.
[0030] The guide groove 13 and guide rod 14 can be used to easily connect the two sets of support pads 12 to the oxygen generator body 1, thereby enhancing the stability of the overall structure and ensuring that the two sets of support pads 12 are limited and guided when sliding up and down, thus preventing the two sets of support pads 12 from shifting when sliding.
[0031] Both sets of support pads 12 have anti-slip pads glued to their lower surfaces, and the lower surfaces of the anti-slip pads have a wavy texture.
[0032] By installing anti-slip pads, the friction between the two sets of support pads 12 and the ground can be increased, further improving the stability of the overall structure, preventing slippage during use, and enhancing overall safety.
[0033] The two sets of support rods 11, which are rotatably installed at the lower ends of the two sets of sleeve blocks 9 in the adjustment cavity 7, are arranged in a figure-eight shape.
[0034] The two sets of support rods 11 at the lower end of the two sets of sleeve blocks 9 are in a figure-eight shape, which can further enhance the support stability of the two sets of support pads 12 on the oxygen generator body 1, making the oxygen generator body 1 more stable after being lifted, and less prone to shaking or tipping, thereby improving the safety and reliability of the overall structure.
[0035] Working Principle: During use, when the height of the oxygen concentrator body 1 needs to be adjusted, the adjustment knob 17 is rotated. The rotation of the adjustment knob 17 drives two sets of bidirectional threaded rods 8 to rotate within two sets of adjustment chambers 7 via two sets of synchronous pulleys 15 and synchronous belts 16. Simultaneously, the rotation of the two sets of bidirectional threaded rods 8 drives four sets of sleeve blocks 9 to move within the two sets of adjustment chambers 7 via the threads. The movement of the four sets of sleeve blocks 9 also drives the guide blocks 10 to slide within four sets of sliding grooves 6. Simultaneously, the movement of the four sets of sleeve blocks 9 drives two sets of support pads 12 to slide up and down via the support rods 11 mounted at the lower end. As the two sets of support pads 12 move, the anti-slip pads glued at the lower end contact the ground, supporting the oxygen concentrator body 1. Furthermore, the movement of the multiple sets of guide rods... The sliding within the four sets of guide grooves 13 can limit and guide the support pad 12, preventing it from shifting during movement. When the oxygen concentrator body 1 needs to be moved, the adjustment knob 17 is rotated in the opposite direction. The rotation of the adjustment knob 17 drives the two sets of bidirectional threaded rods 8 to rotate within the two sets of adjustment chambers 7 via the two sets of synchronous pulleys 15 and synchronous belts 16. Simultaneously, the rotation of the two sets of bidirectional threaded rods 8 drives the four sets of sleeve blocks 9 to move within the two sets of adjustment chambers 7 via the threads. The four sets of sleeve blocks 9 drive the four sets of support rods 11 to move in the opposite direction. The four sets of support rods 11 drive the four sets of support pads 12 to move in the opposite direction, causing the anti-slip pads to separate from the ground. The oxygen concentrator body 1 can then be moved via the four sets of locking casters 2.
[0036] 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.
