Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen concentrator technology, specifically to an oxygen concentrator with a convenient filter replacement. Background Technology
[0002] An oxygen concentrator is a machine that produces oxygen. Its principle is based on air separation technology. First, air is compressed to a high density, then the different condensation points of the air components are used to separate the gas and liquid phases at a specific temperature. Finally, distillation is performed to separate the oxygen and nitrogen. Because it is primarily used to produce oxygen, it is commonly called an oxygen concentrator. Due to the wide range of uses for oxygen and nitrogen, oxygen concentrators are widely used in the national economy, especially in industries such as metallurgy, chemical engineering, petroleum, and defense.
[0003] Existing oxygen concentrators typically have filters mounted on the outside of the air inlet via multiple bolts. These filters, along with other intake, exhaust, and filtration components within the adsorption cylinder, purify the gas. However, replacing the filters is inconvenient and time-consuming. Furthermore, the air inlet filter is prone to clogging with dust and impurities. If not cleaned promptly, this can impede airflow into the oxygen concentrator. Additionally, the long oxygen outlet pipe is easily obstructed by external objects, causing the concentrator to shift and negatively impacting the user experience. Therefore, this paper proposes an oxygen concentrator with easily replaceable filters to address these issues. Utility Model Content

[0024] 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.
[0025] In the embodiments, by Figure 1-5This invention discloses an oxygen concentrator with convenient filter replacement. The invention includes an oxygen concentrator body 1, a filter cartridge 2 fixedly connected inside the oxygen concentrator body 1, an mounting block 3 engaged inside the filter cartridge 2, a filter cartridge 4 fixedly connected to the outer side of the mounting block 3, a mounting frame 6 hinged inside the oxygen concentrator body 1, a filter screen 7 fixedly connected inside the mounting frame 6, a rotating disk 8 rotatably connected inside the filter screen 7, a cleaning brush 9 fixedly connected to the outer side of the rotating disk 8 and contacting the inside of the filter screen 7, a handle 10 fixedly connected to the outer side of the rotating disk 8, a first fixed cylinder 11 slidably connected to the outer side of the oxygen concentrator body 1, a connecting column 12 slidably connected inside the first fixed cylinder 11, a limit plate 13 fixedly connected to the bottom of the connecting column 12, a connecting pipe 14 fixedly connected to the top of the first fixed cylinder 11, a second fixed cylinder 15 fixedly connected to the outer side of the connecting pipe 14, and a sliding column 16 slidably connected inside the second fixed cylinder 15.
[0026] By opening the mounting frame 6, and then holding the handle 5, the mounting block 3 is pulled to remove the filter element 4. The new filter element 4 and mounting block 3 are then inserted into the filter cartridge 2 via the handle 5. The mounting frame 6 and filter screen 7 are closed to prevent external insects and impurities from entering. When the filter screen 7 becomes clogged with dust, the handle 10 is turned to rotate the cleaning brush 9. The cleaning brush 9 removes the dust from the filter screen 7, preventing dust and other impurities from clogging it and affecting airflow. The push plate 18 is pressed to the left to rotate... Rotating plate 19 causes push plate 18 to be abutted by the inside of rotating plate 19, preventing sliding column 16 from returning to its original position. This causes sliding column 16 to slide to the left. Subsequently, sliding column 16 drives second piston to slide inside second fixed cylinder 15, allowing gas inside second fixed cylinder 15 to enter connecting pipe 14. Then, gas enters first fixed cylinder 11 through connecting pipe 14. The gas drives first piston to slide inside first fixed cylinder 11, causing connecting column 12 to drive limiting plate 13 to move downwards until it abuts the ground, thereby preventing the device from moving arbitrarily.
[0027] Specifically, refer to Figure 3 and Figure 5 The outer side of the mounting block 3 is fixedly connected to a handle 5, and the inner side of the oxygen generator body 1 is slidably connected to a first fixed post 17 that is slidably connected to the inner side of the mounting frame 6.
[0028] In this embodiment, by holding the handle 5, the installation block 3 is pulled to remove the filter element 4. Then, the new filter element 4 and the installation block 3 are inserted into the filter cartridge 2 through the handle 5. The installation frame 6 and the filter screen 7 are closed, and the first fixing post 17 is pressed into the oxygen generator body 1 to complete the position fixing of the installation frame 6.
[0029] Specifically, refer to Figure 4The top of the connecting column 12 is fixedly connected to a first piston located inside the first fixed cylinder 11, and the left side of the sliding column 16 is fixedly connected to a second piston located inside the second fixed cylinder 15.
[0030] Specifically, refer to Figure 2 and Figure 4 The bottom of the limiting plate 13 is fixedly connected to an anti-slip pad, the right side of the sliding column 16 is fixedly connected to a push plate 18, and the outer side of the oxygen generator body 1 is rotatably connected to a rotating plate 19.
[0031] In this embodiment, by pressing the push plate 18 to the left, the sliding column 16 slides to the left. Then, the sliding column 16 drives the second piston to slide inside the second fixed cylinder 15, allowing the gas inside the second fixed cylinder 15 to enter the connecting pipe 14, and then enter the first fixed cylinder 11 through the connecting pipe 14. The gas drives the first piston to slide inside the first fixed cylinder 11, thereby causing the connecting column 12 to move the limiting plate 13 downward until it contacts the ground, thus preventing the device from moving arbitrarily. The anti-slip pad increases the friction between the limiting plate 13 and the ground, thereby effectively preventing the device from moving.
[0032] Specifically, refer to Figure 5 The oxygen generator body 1 has a second fixed column 20 that slides inside, and the second fixed column 20 abuts against the interior of the first fixed column 17.
[0033] In this embodiment, when the first fixing post 17 slides into the oxygen generator body 1, the first fixing post 17 abuts against the second fixing post 20. Then, the second fixing post 20 slides to the right, causing the spring 21 to compress. When the second fixing post 20 abuts against the inner groove of the first fixing post 17, the spring 21 causes the second fixing post 20 to slide to the left, thereby completing the fixation of the position of the first fixing post 17. When it is necessary to remove the first fixing post 17, the second fixing post 20 is pulled forward, thereby causing the spring 21 to compress. Then, the first fixing post 17 can be removed to open the mounting frame 6.
[0034] Specifically, refer to Figure 4 and Figure 5 A spring 21 is fixedly connected to the outside of the second fixed column 20, and a caster wheel 22 is installed at the bottom of the oxygen generator body 1.
[0035] In this embodiment, the caster wheel 22 makes the device move more easily, and the spring 21 allows the second fixed post 20 to slide back into the first fixed post 17.
[0036] Working principle:
[0037] First: Open the mounting frame 6, then hold the handle 5 to pull the mounting block 3 to remove the filter element 4. Then, insert the new filter element 4 and the mounting block 3 into the filter cartridge 2 through the handle 5. Close the mounting frame 6 and the filter screen 7 to prevent external flying insects, impurities, etc. from entering. When the filter screen 7 is clogged with dust, turn the handle 10 to drive the cleaning brush 9 to rotate. The cleaning brush 9 removes the dust inside the filter screen 7, thereby preventing dust and other impurities from clogging the filter screen 7 and affecting the air intake.
[0038] Then: by pressing the push plate 18 to the left, the sliding column 16 slides to the left. Subsequently, the sliding column 16 drives the second piston to slide inside the second fixed cylinder 15, allowing the gas inside the second fixed cylinder 15 to enter the connecting pipe 14, and then enter the first fixed cylinder 11 through the connecting pipe 14. The gas drives the first piston to slide inside the first fixed cylinder 11, thereby causing the connecting column 12 to move the limiting plate 13 downward until it touches the ground, thus preventing the device from moving arbitrarily.
