Description

Technical Field

[0001] This utility model relates to the field of oxygen concentrator technology, specifically an improved small home oxygen concentrator. Background Technology

[0002] An oxygen generator is a type of machine that produces oxygen. Its principle is to use air separation technology. First, the air is compressed at 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. Then, it is further refined by distillation. Modern oxygen generators can efficiently produce oxygen to meet the needs of users after they are turned on.

[0003] Existing small home oxygen concentrators, typically 1-5 liter models, have air inlet filters that are easily clogged by dust, hair, and other impurities. Over time, this can affect the air intake of the concentrator. Cleaning the filters is time-consuming and laborious, and the oxygen tubing is also quite long and requires manual winding after use, which is time-consuming, laborious, and inconvenient. Therefore, an improved small home oxygen concentrator is proposed to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0025] 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.

[0026] In the embodiments, by Figure 1-5 An improved small home oxygen concentrator is provided. This utility model includes an oxygen concentrator body 1, an internally slidingly connected mounting frame 2, an internally fixedly connected filter plate 3, an internally fixedly connected first spring 4 fixedly connected to the external side of the mounting frame 2, an internally fixedly connected first motor 5 to the internal bottom wall of the oxygen concentrator body 1, an internally fixedly connected rotating column 6 rotatably connected to the internal part of the oxygen concentrator body 1 to the output shaft of the first motor 5, an externally fixedly connected cam 7 that abuts against the filter plate 3 to the external side of the rotating column 6, an internally fixedly connected second motor 8 to the internal part of the oxygen concentrator body 1, an internally fixedly connected take-up wheel rotatably connected to the internal part of the oxygen concentrator body 1 to the output shaft of the second motor 8, an externally rotatably connected reciprocating screw 10 to the external side of the oxygen concentrator body 1, an externally threaded sliding block 11 to the external side of the reciprocating screw 10, an internally slidingly connected oxygen tube 12 to the sliding block 11, and an externally fixedly connected third motor 9 whose output shaft is fixedly connected to the reciprocating screw 10.

[0027] Start the first motor 5, causing the rotating column 6 to drive the cam 7 to rotate, causing the filter plate 3 to slide along the mounting frame 2, thereby compressing the first spring 4 and then restoring it, thus shaking the dust on the outside of the filter plate 3 into the inner bottom wall of the oxygen generator body 1. Insert the oxygen tube into the interior of the oxygen generator body 1 through the sliding block 11. Then start the second motor 8, causing the winding wheel to rotate, thereby winding the oxygen tube 12 on the outside of the winding wheel. At the same time, start the third motor 9, causing the reciprocating screw 10 to rotate, driving the sliding block 11 to slide left and right, thereby making the oxygen tube 12 evenly wound on the outside of the winding wheel.

[0028] Specifically, refer to Figure 2 The oxygen generator body 1 has a number of gears 13 arranged in a linear array inside, and a rotating rod 14 is fixedly connected to the outside of the middle gear 13. The outer side of the gear 13 is fixedly connected to a blade 15 that is rotatably connected to the inside of the oxygen generator body 1.

[0029] In this embodiment, rotating the rotating rod 14 causes the intermediate gear 13 to rotate, which in turn drives the lower gear 13 and the upper gear 13 to rotate simultaneously, thereby opening the blades 15 to facilitate the entry of air. When the oxygen generator body 1 is not in use, rotating the rotating rod 14 causes the intermediate gear 13 to drive the other gears 13 to rotate, thereby closing the blades 15 to prevent dust and impurities from entering.

[0030] Specifically, refer to Figure 3 and Figure 4 The oxygen generator body 1 has an installation groove 16 inside, and the inner wall of the installation groove 16 is rotatably connected to the winding wheel.

[0031] Specifically, refer to Figure 4 A second spring 17 is fixedly connected to the inner wall of the mounting groove 16, and a limit piece 18 is fixedly connected to the end of the second spring 17 away from the mounting groove 16.

[0032] In this embodiment, the limiting piece 18 limits the oxygen tube 12 that is wound on the outside of the winding wheel, thereby squeezing the oxygen tube 12 and making the oxygen tube 12 wound more neatly.

[0033] Specifically, refer to Figure 3 A synchronization rod 19 is fixedly connected to the outside of the oxygen generator body 1, and the sliding block 11 is slidably connected to the inside of the synchronization rod 19.

[0034] In this embodiment, the synchronizing rod 19 limits the sliding block 11 to prevent the sliding block 11 from rotating with the rotation of the reciprocating screw 10, so that the oxygen tube 12 can be neatly wound up.

[0035] Specifically, refer to Figure 1 and Figure 3The control panel 20 is fixedly connected to the outside of the oxygen generator body 1, and a sliding hole is opened inside the oxygen generator body 1, and the oxygen pipe 12 is slidably connected to the inside of the sliding hole.

[0036] In this embodiment, the control panel 20 controls the periodic cleaning of dust on the outside of the filter plate 3 inside the oxygen generator body 1, the winding of the oxygen tube 12, and the use of the oxygen generator body 1. The oxygen tube 12 slides inside the sliding hole, thereby making the winding of the oxygen tube 12 more uniform and neat.

[0037] Working principle:

[0038] First: Start the first motor 5, so that the rotating column 6 drives the cam 7 to rotate, so that the filter plate 3 drives the mounting frame 2 to slide, thereby compressing the first spring 4 and then restoring it, thus shaking the dust on the outside of the filter plate 3 into the inner bottom wall of the oxygen generator body 1, and extending the oxygen tube into the interior of the oxygen generator body 1 through the sliding block 11.

[0039] Then: The second motor 8 is started to rotate the winding wheel, so that the oxygen tube 12 is wound up on the outside of the winding wheel. At the same time, the third motor 9 is started to rotate the reciprocating screw 10, which drives the sliding block 11 to slide left and right, so that the oxygen tube 12 is wound up evenly on the outside of the winding wheel.
