Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, and in particular relates to an oxygen concentrator with a filtering function. Background Art

[0002] Oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at a high density, and then the different condensation points of the components in the air are used to separate the gas and liquid at a certain temperature, and then distilled to separate it into oxygen and nitrogen. In general, since it is mostly used to produce oxygen, people are accustomed to calling it an oxygen generator.

[0003] The oxygen concentrators currently available on the market have the following problems in actual use:

[0004] 1. When the traditional oxygen concentrator is actually used, it needs to absorb the air from the outside world during operation. The air in the outside environment is messy, and the oxygen concentrator itself does not have a device to filter the particles in the air. At this time, when the oxygen concentrator absorbs the outside air, some particles may be sucked into the inside of the oxygen concentrator, and the filtering effect is usually not strong;

[0005] 2. During the use of most oxygen concentrators, since the oxygen concentrators need to be moved to a suitable location for installation before use, the oxygen concentrators may collide with the wall during the movement. Most oxygen concentrators themselves do not have anti-collision devices. At this time, the oxygen concentrators may be damaged after the collision, and the protection is poor during use.

By installing the filter screen 9, when the oxygen concentrator is running to absorb the outside air, the filter screen 9 will filter the outside air, filter the particulate matter in the air, and prevent the particulate matter from entering the interior of the oxygen concentrator, and the filtering effect is relatively good.

[0031] A first side plate 12 is welded to the side of the oxygen concentrator body 1, and a buffer assembly 11 is provided on the side of the first side plate 12. The buffer assembly 11 includes a first fixing seat 15, a second fixing seat 17, a spring 16, a first shaft rod 18, a second shaft rod 19, and an extrusion plate 14. The first fixing seat 15 is welded to the side of the first side plate 12, and the other end of the first fixing seat 15 is fixedly connected to the first shaft rod 18. A second shaft rod 19 is provided inside the first shaft rod 18, and the other end of the second shaft rod 19 is fixedly connected to the second fixing seat 17. The spring 16 is welded to the other end of the first fixing seat 15, and the other end of the spring 16 is welded to the second fixing seat 17. The extrusion plate 14 is welded to the other end of the second fixing seat 17. The second side plate 13 is welded to the surface of the oxygen concentrator body 1, and the surface of the second side plate 13 is connected to the buffer assembly 11. Through the installation of the buffer assembly 11, when the oxygen concentrator collides with the wall during movement, the buffer assembly 11 will buffer the force of the collision on the oxygen concentrator, reduce the collision force for the oxygen concentrator, and have strong protection when used.

[0032] An iron sheet 7 is welded on the top of the second fixed frame 6, and a magnet block 8 is provided on the outside of the second fixed frame 6. The magnet block 8 is embedded in the top of the first fixed frame 4, and the bottom of the iron sheet 7 is attached to the top of the magnet block 8. By installing the magnet block 8 and the iron sheet 7, the second fixed frame 6 is fixed inside the first fixed frame 4 by utilizing the magnetic attraction effect, which is very convenient to use.

[0033] A support rod 20 is welded to the side of the oxygen concentrator body 1, and a support plate 22 is welded to the other end of the support rod 20. The top of the support plate 22 is fixedly connected to an internal threaded seat 21. A screw rod 23 is installed inside the internal threaded seat 21. A bottom plate 24 is welded to one end of the screw rod 23, and a turntable 27 is welded to the other end of the screw rod 23. By installing the screw rod 23, when the oxygen concentrator body 1 is moved to a suitable position, the screw rod 23 can be rotated to squeeze the bottom plate 24 downward, thereby achieving a fixing effect for the oxygen concentrator body 1, and having greater stability during use.

[0034] The back of the oxygen concentrator body 1 is fixedly connected to the third fixing seat 25, and a handle 26 is welded to the other end of the third fixing seat 25.

[0035] The first side plate 12 is symmetrically distributed, and the second side plate 13 is symmetrically distributed. Through the distribution of the first side plate 12, when the oxygen concentrator body 1 is collided, the collision force can be evenly dispersed, thereby reducing the impact force on the oxygen concentrator body 1, and the protection is stronger during use.

[0036] The working principle of the oxygen concentrator with filtering function: when using the oxygen concentrator with filtering function, the fixing ring 3 should be fixed on the fixing plate 2 by bolts first. Since the fixing ring 3 is fixedly connected to the first fixing frame 4, the first fixing frame 4 is also fixed on the fixing plate 2 at this time. Then, the second fixing frame 6 is installed inside the first fixing frame 4 by using the slide groove 5, and the filter screen 9 is installed inside the second fixing frame 6. Then, the bottom of the iron sheet 7 is attached to the top of the magnet block 8. By installing the magnet block 8 and the iron sheet 7, the second fixing frame 6 is fixed inside the first fixing frame 4 by using the magnetic effect. It is very convenient to use. When the oxygen concentrator is running and absorbing the outside air, the filter screen 9 will filter the outside air and filter the particles in the air. It will not allow particles to enter the interior of the oxygen concentrator, and it has strong protection when in use. When it is necessary to move the oxygen concentrator with a filtering function, the universal wheel 10 can be directly driven by the handle 26 to move the oxygen concentrator with a filtering function. During the movement, if it collides with a wall, the buffer component 11 will buffer the force of the collision on the oxygen concentrator to reduce the collision force for the oxygen concentrator. It has strong protection when in use. When colliding, it will first collide with the extrusion plate 14, and then the collision force will be dispersed by the spring 16, so as to achieve an anti-collision effect for the oxygen concentrator body 1. After moving to a suitable position, the screw rod 23 can be rotated to squeeze the bottom plate 24 downward to achieve a fixing effect for the oxygen concentrator body 1, and it has strong stability when in use.
