It should be understood that the present application is not limited to the described embodiments. On the contrary, the present application includes all modifications, variations and equivalents that fall within the scope of the attached claims.

[0058] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0059] The present application provides an oxygen storage device, which can be applied to a portable oxygen concentrator. Figure 1 is a three-dimensional diagram of a portable oxygen concentrator according to an embodiment of the present application. Figure 2 is a three-dimensional diagram of a portion of a portable oxygen concentrator according to an embodiment of the present application. Figure 3 is along Figure 2 A cross-sectional view along the AA direction is shown.

[0060] like Figure 2 As shown, the portable oxygen concentrator 1 (such as Figure 1 The oxygen generator 10 includes an oxygen production unit 10 and an oxygen storage device 20. The oxygen production unit 10 of the embodiment of the present application may be an oxygen production unit based on the principle of pressure swing adsorption, for example, oxygen is separated from compressed air by a molecular sieve, but the embodiment of the present application is not limited to this, and the oxygen production unit 10 may be an oxygen production unit based on any oxygen production principle. The oxygen storage device 20 is used to store the oxygen or oxygen-rich gas produced by the oxygen production unit 10.

[0061] like Figure 2 As shown, the oxygen production part 10 extends in the axial direction, the oxygen storage device 20 is fixed at one axial end of the oxygen production part 10 , and the oxygen storage device 20 in the oxygen storage state surrounds the radial outer side of the oxygen production part 10 .

[0062] Therefore, by arranging the oxygen storage device 20 to surround the radially outer side of the oxygen generator 10, the internal space of the portable oxygen generator 1 can be effectively utilized, thereby further reducing the volume of the oxygen generator and improving the portability of the oxygen generator.

[0063] In the embodiment of the present application, the direction along the central axis OO of the oxygen production section 10 or the direction parallel to the central axis OO is called "axial", the radial direction centered on the central axis OO is called "radial", the direction radially away from the central axis OO is called "radial outside", the direction radially close to the central axis OO is called "radial inside", and the circumferential direction centered on the central axis OO is called "circumferential".

[0064] In addition, optionally, the oxygen production section 10 is columnar, for example, the oxygen production chamber of the oxygen production section 10 may be cylindrical or prismatic, etc., and the embodiment of the present application does not limit this. In addition, the oxygen production chamber of the oxygen production section 10 may be formed by two or more molecular sieve cylinders arranged inside and outside, or may be formed by a plurality of molecular sieves having a fan-shaped, triangular, or trapezoidal cross section, etc., and the embodiment of the present application does not limit this.

[0065] In addition, the gas stored in the oxygen storage device 20 of the embodiment of the present application can be pure oxygen or oxygen-rich gas. The oxygen storage state of the oxygen storage device 20 refers to the storage of oxygen-containing gas, such as pure oxygen or oxygen-rich gas, in the oxygen storage device 20. The embodiment of the present application is not limited to this.

[0066] like Figure 3 As shown, the oxygen outlet 101 of the oxygen production unit 10 is connected to the air inlet 201 of the oxygen storage device 20. For example, the air inlet 201 of the oxygen storage device 20 is provided with a one-way valve 202, and the one-way valve 202 is used to allow the gas to flow from the oxygen outlet 101 of the oxygen production unit 10 to the air inlet 201 of the oxygen storage device 20 (such as Figure 3 The flow direction is indicated by the arrow, but the flow cannot be reversed.

[0067] like Figure 3 As shown, the one-way valve 202 includes, for example, a reed 221 and a bolt 222 for fixing the reed 221. One end of the reed 221 is fixed to the inner side of the air inlet 201 of the oxygen storage device 20, and the other end of the reed 221 is suspended between the air inlet 201 and the oxygen outlet 101. The suspended end of the reed 221 can be displaced into the air inlet 201 but cannot be displaced into the oxygen outlet 101. In this way, under the pressure of the gas flowing from the oxygen outlet 101 to the air inlet 201, the suspended end of the reed 221 is displaced into the air inlet 201 so that the gas can enter the oxygen storage device 20 from the gap between the reed 221 and the inner wall of the air inlet 201, while the gas in the oxygen storage device 20 cannot overflow from the air inlet 201 to the oxygen outlet 101 in the opposite direction.

[0068] In addition, optional, such as Figure 2 As shown, the oxygen storage device 20 also has an air outlet 203, and a pressure regulating valve 204 for stabilizing the gas flow rate is arranged outside the air outlet 203. Therefore, when the user uses the oxygen storage device 20 to inhale oxygen, the oxygen gas flow is stably discharged through the pressure regulating valve 204, thereby improving the user's oxygen inhalation experience.

[0069] In some embodiments, the oxygen storage device 20 may be made of a hard material, so that the shape of the oxygen storage device 20 is fixed, that is, the shape in the oxygen storage state is the same as the shape in the non-oxygen storage state. Optionally, the oxygen storage device 20 may also be made of a flexible material, so that the shape of the oxygen storage device 20 is not fixed, that is, the shape in the oxygen storage state is different from the shape in the non-oxygen storage state. For example, the oxygen storage device 20 may be deflated when not inflated, and may be in a shape surrounding the radially outer side of the oxygen production unit 10 when inflated. The oxygen storage device 20 may be in the shape of a "bag" or an "air bag".

[0070] Figure 4 is a schematic diagram of an implementation of an oxygen storage device in an embodiment of the present application, Figure 5 is a schematic diagram of another embodiment of the oxygen storage device of the present application. Figure 6 It is a schematic diagram of another implementation of the oxygen storage device of the embodiment of the present application.

[0071] In some embodiments, the oxygen storage device 20 is in the shape of a ring in the oxygen storage state. The "ring" described in the embodiments of the present application can be a complete ring or an incomplete ring, that is, a part of a ring. For example, Figure 4 As shown, the oxygen storage device 20 is a part of a circular ring, or it can be said that the oxygen storage device 20 is a sector-shaped ring, but the embodiment of the present application is not limited to this, and the oxygen storage device 20 can also be a complete circular ring.

[0072] In addition, the "ring shape" described in the embodiment of the present application may not be limited to a "circular ring shape", that is, the "ring shape" described in the embodiment of the present application may be any ring shape. In order to achieve effective use of the internal space of the oxygen generator, the shape of the oxygen storage device 20 may be set according to the shape of the outer surface of the oxygen generator 10.

[0073] For example, the oxygen generator 10 may be a prism with a polygonal axial section, and the oxygen storage device 20' may be a polygonal ring or a part of a polygonal ring. Figure 5 As shown, the oxygen storage device 20' can be a complete hexagonal ring, but the embodiment of the present application is not limited thereto. Figure 6 As shown, the oxygen storage device 20" may also be a part of a hexagonal ring, for example, the oxygen storage device 20" may be a broken line consisting of three sides. In addition, the oxygen storage device may also include only one side, for example, the oxygen storage device may be a cuboid extending along one side of the outer surface of the prismatic oxygen production part. The above description is made using the oxygen production part 10 as a hexagonal prism as an example, and the oxygen production part 10 as other polygonal prisms or other shapes can be deduced by analogy, which will not be described one by one here.

[0074] According to the oxygen storage device of the embodiment of the present application, by arranging the oxygen storage device to surround the radial outside of the oxygen generator, the internal space of the oxygen generator can be effectively utilized, thereby further reducing the volume of the oxygen generator and improving the portability of the oxygen generator.

[0075] The embodiment of the present application also provides a portable oxygen concentrator, which includes the oxygen storage device described in any of the above embodiments. Since the structure of the oxygen storage device has been described in detail above, its content is incorporated here and the description is omitted here. In addition, the portable oxygen concentrator of the embodiment of the present application can refer to the structure of the portable oxygen concentrator 1 described in the above embodiment.

[0076] For example, Figure 2 As shown, the portable oxygen concentrator 1 may include an oxygen production part 10 extending axially, an oxygen storage device 20 is fixed at one axial end of the oxygen production part 10, an oxygen outlet 101 of the oxygen production part 10 is unidirectionally connected to an air inlet 201 of the oxygen storage device 20, and the oxygen storage device 20 in the oxygen storage state surrounds the radial outer side of the oxygen production part 10.

[0077] In addition, optional, such as Figure 2 and Figure 3 As shown, the oxygen production unit 10 may include a cover member 102 located on one side of the axial direction. Figure 3 As shown, the oxygen outlet 101 of the oxygen production unit 10 is arranged on the end surface 121 of the cover member 102 facing the other axial side, and the oxygen storage device 20 can also be fixed to the end surface 121 of the cover member 102, for example, fixed to the end surface 121 of the cover member 102 by bolts or the like.

[0078] In some embodiments, Figure 2 As shown, the portable oxygen concentrator 1 may further include a power supply device 30 .

[0079] Figure 7 is a schematic diagram of an implementation of a power supply device according to an embodiment of the present application, Figure 8 It is a schematic diagram of another implementation of the power supply device of the embodiment of the present application.

[0080] In the embodiment of the present application, similar to the oxygen storage device 20, the power supply device 30 can be surrounded by the radial outer side of the oxygen production unit 10, and the power supply device 30 can be annular. The "annular" described in the embodiment of the present application can be a complete ring or an incomplete ring, that is, a part of a ring. For example, Figure 7 As shown, the power supply device 30 may be a part of a circular ring, or it may be said that the power supply device 30 is a sector-shaped ring, but the embodiment of the present application does not limit this, and the power supply device 30 may also be a complete circular ring.

[0081] In addition, similar to the oxygen storage device 20, the "ring-shaped" described here may not be limited to a "circular ring-shaped". In order to achieve effective use of the internal space of the oxygen generator, the shape of the power supply device 30 may be set according to the shape of the outer surface of the oxygen generator 10.

[0082] In addition, the shape and the position of the power supply device 30 can also be set accordingly according to the shape of the oxygen storage device 20. For example, the shape of the power supply device 30 is similar to that of the oxygen storage device 20.

[0083] For example, Figure 2 As shown in FIG. 1 , the oxygen storage device 20 and the power supply device 30 in the oxygen storage state are both fan-shaped rings, and the oxygen storage device 20 and the power supply device 30 are arranged at different positions in the circumferential direction of the oxygen production unit 10. In addition, the oxygen storage device 20 and the power supply device 30 may overlap a portion in the circumferential direction, or may be arranged as shown in FIG. Figure 2 As shown, they do not overlap, that is, there is a predetermined interval between the oxygen storage device 20 and the power supply device 30 in the circumferential direction. This embodiment of the present application does not limit this.

[0084] In addition, the oxygen storage device 20 and the power supply device 30 in the oxygen storage state can both be in a complete ring shape. In this case, the oxygen storage device 20 and the power supply device 30 can be distributed along the axial direction of the oxygen production unit 10, that is, the oxygen storage device 20 and the power supply device 30 are arranged at different positions in the axial direction of the oxygen production unit 10. In addition, the oxygen storage device 20 and the power supply device 30 may overlap partially in the axial direction, or may not overlap, which is not limited in the embodiment of the present application.

[0085] In addition, if Figure 7 As shown, the power supply device 30 may have an electrical connection portion 301 and a fixing portion 302, which may be respectively arranged on both sides of the axial direction of the power supply device 30, wherein the electrical connection portion 301 may be a metal pick for connecting with a related circuit, and may also realize a fixing function, and the fixing portion 302 is used to fix the power supply device 30 inside the oxygen concentrator, and the fixing portion 302 is, for example, a threaded hole, and the power supply device 30 is fixed by bolts or the like.

[0086] In addition, the power supply device 30 may also be arranged outside the housing of the portable oxygen concentrator 1, that is, the power supply device 30 is arranged separately from other parts of the portable oxygen concentrator 1, and supplies power to the relevant circuits in the portable oxygen concentrator 1 through a power line or the like. Figure 8 As shown, the power supply device 30' may be cylindrical and have a power supply interface 303. The power supply interface 303 may be a universal standard power supply interface, such as a Type-C interface, etc., which is not limited in the embodiment of the present application.

[0087] In addition, the power supply device 30 or 30 ′ may be formed by enclosing a battery pack in a housing, and the battery pack is composed of, for example, 18650 type batteries.

[0088] In addition, the portable oxygen concentrator of the embodiment of the present application may also include other components, for example, a muffler, a nasal oxygen tube, etc. The embodiment of the present application does not limit the specific structure of the portable oxygen concentrator, and it can be designed according to actual needs.
