Description

Technical Field

[0001] The present invention relates to the field of medical technology, and particularly to a waterless humidifying oxygen generator. Background Art

[0002] In the fields of medical treatment and home healthcare, oxygen generators are important devices for providing oxygen support. Traditional oxygen generators have some limitations in design and function, which affect their performance and user experience.

[0003] Traditional oxygen generators usually adopt the method of water humidification and require regular replacement and maintenance of humidification components. This not only increases the maintenance cost and operation complexity for users, but also may lead to bacterial growth and water pollution, affecting the purity and safety of the output oxygen. In addition, the water humidification system has poor adaptability under different environmental humidities and is difficult to meet diverse usage requirements.

[0004] In terms of structural design, traditional oxygen generators usually set up an intake silencing structure to ensure the quietness of the device. This structure increases the complexity of pipeline connection. At the same time, the dehumidification and humidification structure layouts of traditional oxygen generators are not reasonable enough, increasing the bending and crossing of pipelines, affecting the gas flow and the humidification efficiency.

[0112] As Figures 1 to 9 shown, the present invention provides an anhydrous humidifying oxygen generator, including a base 11, and further including:

[0113] A first bracket 12 and a second bracket 13, respectively installed at both ends of the base 11; the first bracket 12 extends outwardly to be provided with a first partition 121 to form a first space and a second space; the second bracket 13 extends outwardly to be provided with a second partition to form a third space and a fourth space;

[0114] An air storage tank 2 and a battery module, respectively disposed in the first space and the third space;

[0115] A molecular sieve 5, horizontally disposed between the second space and the fourth space;

[0116] A compressor 4, disposed between the first bracket 12 and the second bracket 13, and spaced across the upper end of the molecular sieve 5 through a compressor shock mount 10;

[0117] An anhydrous humidifying module 3, installed on the second partition, one side of the anhydrous humidifying module 3 is provided with an anhydrous humidifying module air inlet 31 and an anhydrous humidifying module oxygen outlet 34, and the other side of the anhydrous humidifying module 3 is provided with an anhydrous humidifying module air outlet 32 and an anhydrous humidifying module oxygen inlet 33; the anhydrous humidifying module air inlet 31, the anhydrous humidifying module oxygen outlet 34, the anhydrous humidifying module air outlet 32, and the anhydrous humidifying module oxygen inlet 33 are all oriented towards the compressor 4;

[0118] The anhydrous humidifying module air inlet 31 and the air inlet 26 located on one side of the first bracket 12 are on the same side, and the first pipeline connecting the two passes through between the first bracket 12 and the second bracket 13 and is located on one side of the compressor 4;

[0119] The air outlet 32 of the anhydrous humidification module is connected to the air inlet 41 of the compressor through a second pipeline, and the air inlet 41 of the compressor is located on the other side of the compressor 4;

[0120] An oxygen outlet 21 of the gas storage tank 2 is provided, and the oxygen outlet 21 of the gas storage tank is connected to the oxygen inlet 33 of the anhydrous humidification module through a third pipeline, and the third pipeline is connected to the oxygen inlet 33 of the anhydrous humidification module through the space below the compressor shock absorber 10; the oxygen outlet 34 of the anhydrous humidification module is used for external oxygen supply.

[0121] In order to better introduce the anhydrous humidification oxygen generator of the present invention, the following specific applications are now combined for illustration: First, by separating the air inlet 26 and the anhydrous humidification module 3 at both ends, the length of the first pipeline is increased, and the intake silencing function is realized through the long pipeline structure design, thus replacing the intake silencing structure usually possessed by traditional oxygen generators to ensure the quiet effect of the equipment; at the same time, by making the air inlet and outlet directions and the oxygen inlet and outlet directions of the air oppose each other, the humidification effect is improved. It can be seen that through the above structural layout, not only the traditional intake silencing structure is cancelled through the intake method of the long pipeline, but also the humidification effect is ensured by the gas backwash, and then combined with the overall machine layout, the convenience and compactness of the pipeline connection are improved, and the structural compactness of the portable oxygen generator is realized; the problems that the addition of the intake silencing structure in the existing oxygen generator increases the pipeline complexity and the unreasonable component layout affects the humidification efficiency are solved.

[0122] In some possible embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the anhydrous humidification oxygen generator further includes:

[0123] A pressure equalizing valve 6, located in the second space;

[0124] The pressure equalizing valve oxygen delivery pipeline 25 and the pressure equalizing valve oxygen inlet pipeline 52 are respectively formed by the snap connection of an outwardly protruding extension part and an inwardly concave groove part, and are respectively arranged between the pressure equalizing valve 6 and the gas storage tank 2, and between the pressure equalizing valve 6 and one end of the molecular sieve 5.

[0125] By arranging the pressure equalizing valve 6 inside the second space and connecting it to the gas storage tank 2 and the molecular sieve 5 through the oxygen delivery pipeline 25 of the pressure equalizing valve and the oxygen inlet pipeline 52 of the pressure equalizing valve respectively, the arrangement of pipelines is saved, the structural layout is optimized, and the structure of the oxygen generator is made more compact. The extension part of the oxygen delivery pipeline 25 of the pressure equalizing valve can be arranged above the pressure equalizing valve 6 or below the gas storage tank 2. When the extension part of the oxygen delivery pipeline 25 of the pressure equalizing valve is arranged below the gas storage tank 2, the groove part of the oxygen delivery pipeline 25 of the pressure equalizing valve is arranged above the pressure equalizing valve 6, and the two are snap-connected to deliver the oxygen flowing into the pressure equalizing valve 6 to the gas storage tank 2 through the oxygen delivery pipeline 25 of the pressure equalizing valve. Preferably, a one-way valve can be arranged in the oxygen delivery pipeline 25 of the pressure equalizing valve to make the oxygen flow into the gas storage tank 2 unidirectionally and prevent the oxygen from flowing back; the extension part of the oxygen inlet pipeline 52 of the pressure equalizing valve can be arranged on one side of the pressure equalizing valve 6 or at one end of the molecular sieve 5.

[0134] By integrally arranging the pulse pipeline 62 on the valve seat 61 of the pressure equalizing valve 6, the pipeline layout is reduced, which is beneficial to the compactification of the oxygen generator structure; at the same time, arranging the pulse pipeline intake port 621 and the pulse pipeline outlet 622 on the same side facilitates the connection of the pulse communication channel 22 and the oxygen concentration communication channel 23, saving the pipeline setting; further, integrally arranging the air intake port opening slot, the pulse communication channel 22, and the oxygen concentration communication channel 23 on the air storage tank 2 makes the oxygen generator structure more compact and the layout more reasonable; furthermore, the compressor 4 is arranged in a deflected manner to facilitate the connection of the intake port connector, the inner end of the pulse communication channel 22, and the inner end of the oxygen concentration communication channel 23.
