[0042] Figure 1 Fig. 1 is a structure schematic diagram of a split type oxygen generator according to the embodiment of the present application, which shows the wearing and using situation of the split type oxygen generator. As shown in the figure, the split type oxygen generator 10 comprises an oxygen production part 101, an oxygen storage part 102 and a control part 103. The oxygen production part 101 is used for producing oxygen, and the produced oxygen is input into the oxygen storage part 102 through a first gas outlet; the oxygen storage part 102 stores and delivers the gas from the oxygen production part 101 to the user; the control part 103 is separated from the oxygen production part 101 and the oxygen storage part 102, and controls the oxygen production of the oxygen production part 101. Figure 1

[0043] As shown in the figure, for example, the control part 103 can be separated from the oxygen production part 101, the oxygen production part 101 has a signal transceiver device integrated on a circuit board, and signal transmission is performed between the oxygen production part 101 and the control part 103 through the device. The oxygen production part 101 can be placed in a portable storage member such as a backpack or a sling bag, or can be equipped with a shoulder strap or a buckle strap, so as to be easily carried on the user's body. The control part 103 is, for example, a bracelet or a mobile terminal, which controls the opening and closing of the oxygen production, or controls the speed of the oxygen production, etc. Figure 1

[0044] In the embodiment of the present application, the oxygen storage part 102 comprises an oxygen delivery tube and a compressible gas storage device, the first end of the oxygen delivery tube is connected to the first gas outlet of the oxygen production part, the compressible gas storage device is arranged at the middle part of the oxygen delivery tube, and the compressible gas storage device can change the volume. Figure 1 The compressible gas storage device is not shown in the figure for simplicity, and the compressible gas storage device can refer to the specific implementation of the compressible gas storage device in the embodiment of the present application. Figure 3 .

[0045] Therefore, in the embodiment of the present application, the oxygen production part, the oxygen storage part and the control part are separated, and the compressible gas storage device is arranged at the middle part of the oxygen delivery tube, so as to reduce the size of the oxygen generator body for easy carrying, and to ensure sufficient gas storage space.

[0046] Figure 2 Fig. 2 is a structure schematic diagram of a split type oxygen generator according to the embodiment of the present application.

[0047] In some embodiments, as shown in the figure, the oxygen production part 101 and the oxygen storage part 102 are connected through a connecting pipe 104, and the control part 103 is connected to the oxygen production part 101 through a wireless signal transmission device. Figure 2 ​​As shown, the split-type oxygen concentrator 10 also includes a breathing detection unit 201, a flow regulation unit 202, a display unit 203, and an oxygen delivery unit 204. The breathing detection unit 201, flow regulation unit 202, and display unit 203 are all controlled by the control unit 103. The breathing detection unit 201 is connected to the oxygen delivery tube 1021; the oxygen delivery unit 204 is connected to the breathing detection unit 201; the flow regulation unit 202 is located in the oxygen generation unit 101 or the oxygen storage unit 102; and the display unit 203 is located in the control unit 103 or the oxygen generation unit 101.

[0048] It is worth noting that the above appendix Figure 2 The embodiments described herein are merely illustrative and are not limited thereto. For example, some devices or components may be appropriately added, and some devices or components may be removed. Those skilled in the art can make appropriate modifications based on the above description, and are not limited to the above-described embodiments. Figure 2 The records.

[0049] The oxygen storage section of the embodiments of this application will be further described below.

[0050] Figure 3 This is a schematic diagram of the oxygen storage section according to an embodiment of this application. Figure 3 As shown, the oxygen storage unit 102 includes an oxygen delivery pipe 1021 and a compressible gas storage device 1022. The first end 01 of the oxygen delivery pipe 1021 is connected to the first gas outlet of the oxygen generating unit 101. Figure 3 (Not shown in the image), a compressible gas storage device 1022 is disposed in the middle of the oxygen delivery pipe 1021 and is connected to the two sections of the oxygen delivery pipe 1021a and 1021b respectively, and the compressible gas storage device 1022 can change its volume. This application is not limited to this; for example, the compressible gas storage device 1022 can also be disposed at one end of the oxygen delivery pipe 1021.

[0051] For example, the compressible gas storage device 1022 is a foldable gas storage bag, made of materials such as resin or plastic. When the folded portion of the compressible gas storage device 1022 extends and unfolds axially, the compressible gas storage device 1022 can become a cylinder of a certain length, at which point its gas storage volume increases. When the folded portion of the compressible gas storage device 1022 is compressed and folded axially, the compressible gas storage device 1022 can become a disc-shaped structure, at which point its gas storage volume decreases.

[0052] Therefore, through this compressible gas storage device 1022, users can change the shape and volume of the gas storage device as needed. When more oxygen is needed, the compressible gas storage device 1022 can be unfolded to store more oxygen for the user. When more oxygen is not needed or the oxygen generator is not used, the compressible gas storage device can be folded to reduce its size and make it easier to carry.

[0053] In the embodiments of the present application, the oxygen production part 101 is controlled by the control part 103 to start producing oxygen, and the oxygen enters the oxygen storage part 102 through the first gas outlet of the oxygen production part 101, sequentially passes through the oxygen delivery pipe 1021a, the compressible gas storage device 1022, and the oxygen delivery pipe 1021b, and reaches the oxygen delivery part 204 (such as a nasal oxygen pipe or an oxygen mask, etc.). Thus, by separating the oxygen production part, the oxygen storage part, and the control part of the oxygen generator, the body of the oxygen generator can be reduced to facilitate carrying.

[0054] In some embodiments, at least one one-way valve is arranged in the oxygen delivery pipe 1021 of the oxygen storage part 102, which allows the gas to flow from the oxygen production part 101 to the breath detection part 201 through the oxygen storage part 102 in one direction. The arrangement of the one-way valve allows the oxygen to flow in one direction, preventing backflow or other chaotic gas from entering the oxygen storage part 102, so that the oxygen can be normally delivered and the purity of the oxygen is ensured.

[0055] In some embodiments, as shown in Figure 3 the one-way valve includes a first one-way valve 301 located at the second end 02 of the oxygen delivery pipe 1021 and a second one-way valve 302 located at one end of the compressible gas storage device 1022.

[0056] In some embodiments, a control valve is arranged in the oxygen delivery pipe 1021 of the oxygen storage part 102, which opens or closes the flow of gas in the oxygen delivery pipe according to the detection result of the breath detection part.

[0057] Figure 4 is a schematic diagram of the position of the control valve in the embodiments of the present application. As shown in Figure 4 the control valve 303 is located at the second end 02 of the oxygen delivery pipe 1021 and is in communication connection with the breath detection part 201. Thus, the control valve 303 can control the delivery of oxygen according to the signal of the breath detection part 201, improving the oxygen experience of the user.

[0058] For example, the opening and closing of the control valve 303 and the opening degree can be adjusted according to the user's breathing parameters detected by the breath detection part 201: when the user exhales, the control valve 303 is actively closed to prevent chaotic gas from entering the oxygen storage part 102; when the user inhales, the control valve is actively opened to allow the oxygen to be smoothly output.

[0059] In the embodiments of the present application, the one-way valve and the control valve can have different combinations, which are exemplarily described below.

[0060] Figure 5 is another schematic diagram of the oxygen storage part in the embodiments of the present application. As shown in Figure 5As shown, the compressible gas storage device 1022 has a third end 1022a and a fourth end 1022b.

[0061] In some embodiments, the first one-way valve 301 is located in the oxygen delivery pipe 1021b, and the specific location in the oxygen delivery pipe 1021b is not limited, for example, it can be closer to the second end 02 of the oxygen delivery pipe 1021b, or closer to the fourth end 1022b of the compressible gas storage device 1022. The second one-way valve 302 is located at the third end 1022a of the compressible gas storage device 1022, and the control valve 303 is located at the second end 02 of the oxygen delivery pipe 1021b.

[0062] In other embodiments, the first one-way valve 301 and the second one-way valve 302 are both located at the end of the compressible gas storage device. For example, the first one-way valve 301 is located at the third end 1022a, and the second one-way valve 302 is located at the fourth end 1022b, or the first one-way valve 301 is located at the fourth end 1022b, and the second one-way valve 302 is located at the third end 1022a. The control valve 303 is located at the second end 02 of the oxygen delivery pipe 1021b.

[0063] In other embodiments, the oxygen delivery pipe 1021 of the oxygen storage part 102 does not have the first one-way valve 301, but has the second one-way valve 302. The second one-way valve 302 is located at the third end 1022a or the fourth end 1022b of the compressible gas storage device 1022. The control valve 303 is located at the second end 02 of the oxygen delivery pipe 1021b.

[0064] In some embodiments, the oxygen delivery pipe 1021 does not have the control valve 303, but has one-way valves, and the combination of the one-way valves can be any of the above or other cases, in addition, the one-way valves and the control valve can be replaced with each other, and the present application does not limit this.

[0065] In the embodiments of the present application, the compressible gas storage device 1022 can change the size of the volume, and by compression, a large amount of oxygen can be supplied in a short time, and by expanding again, the oxygen can be stored again, thereby meeting the needs of the user in various situations.

[0066] For example, if the compressible gas storage device 1022 stores a large amount of oxygen after being expanded, in some emergency oxygen supply situations, the compressible gas storage device 1022 can be manually compressed, and due to the presence of the one-way valve at the third end 1022a, the oxygen in the compressible gas storage device 1022 will flow rapidly from the fourth end 1022b after being compressed, thereby achieving the effect of supplying a large amount of oxygen in a short time.

[0067] In some embodiments, the compressible oxygen storage device 1022 can be detached from the oxygen delivery tube 1021, which can be connected to the oxygen delivery tube 1021 through a threaded port or a bayonet port, or the like, and the application does not limit the connection mode.

[0068] For example, as shown in Figure 5 The third end 1022a of the compressible oxygen storage device 1022 close to the oxygen generating part 101 can be detached from the oxygen delivery tube 1021a, and / or the fourth end 1022b of the compressible oxygen storage device 1022 away from the oxygen generating part 101 can be detached from the oxygen delivery tube 1021b. The detached compressible oxygen storage device can be used as a simple artificial respiration device, so as to be used as a first-aid tool in an emergency requiring artificial respiration.

[0069] The above exemplary describes the oxygen storage part, and the following describes the breathing detection part and other components of the application.

[0070] In the existing breathing detection mode, the breathing detection part or the flow detection part is generally arranged on the body of the oxygen generator, for example, close to the first gas outlet of the oxygen generating part. The breathing change needs to be detected by the breathing detection device through a long oxygen delivery tube, which makes the measured data not accurate for the user.

[0071] In the embodiment of the application, as shown in Figure 4 The breathing detection part 201 can be arranged at the second end 02 of the oxygen delivery tube 1021, which is away from the first gas outlet 1011 of the oxygen generating part 101, to detect the breathing of the user.

[0072] The breathing detection part 201 of the application is located at the end of the oxygen delivery tube 1021 away from the first gas outlet 1011 of the oxygen generating part 101 and close to the oxygen delivery part 204. Since the breathing detection part 201 is close to the user, the data measured by the breathing detection part 201 is more accurate, which can further improve the accuracy and sensitivity of the breathing detection device.

[0073] For example, the breathing detection part 201 can utilize one or more of the combination of pressure detection principle, flow detection principle, temperature detection principle, humidity detection principle, optical detection principle and sensor fusion principle, and the application does not limit this. For specific content or structure of breathing detection, please refer to related technology, which will not be described here.

[0074] In the embodiment of the application, the flow regulating part 202 is arranged at the oxygen generating part 101 or the oxygen storage part 102 to control the oxygen flow and / or speed through the oxygen delivery tube 1021.

[0075] For example, the flow regulating part 202 is arranged in the oxygen generating part 101, and the reaction of controlling the flow and / or speed of the oxygen is more rapid; the flow regulating part 202 is arranged in the oxygen storage part 102, and the control of the flow and / or speed of the oxygen is more obvious to the human perception. The flow regulating part 202 can be a switch or a valve, and can be manually controlled or controlled by the control part 103. The implementation form of the flow regulating part is not limited in the present application.

[0076] In the embodiment of the present application, the oxygen supply part 204 has a second gas outlet 2041, and the oxygen supply part 204 is connected to the breath detection part 201. Figure 4 In the embodiment of the present application, the second end part 02 of the oxygen supply pipe 1021 is provided with the breath detection part 201 and the oxygen supply part 204. The user can use the oxygen by placing the second gas outlet 2041 of the oxygen supply part 204 close to the mouth and nose. The oxygen supply part 204 can be a nasal oxygen pipe or an oxygen mask, and the present application is not limited thereto.

[0077] In some embodiments, the control valve 303 can open or close the flow of the gas in the oxygen supply pipe 1021 according to the detection result of the breath detection part 201, and / or the oxygen supply part 204 can output the gas in the oxygen supply pipe 1021 from the second gas outlet 2041 according to the detection result of the breath detection part 201. Thus, the breath detection part can be linked with the control valve and the oxygen supply part, and can bring a better breathing experience to the user.

[0078] In the embodiment of the present application, the control part 103 can communicate with the breath detection part 201 wirelessly. The breath detection part 201 has a signal transceiver, and the control part 103 can send a detection signal to the breath detection part 201. The breath detection part 201 receives the detection signal and performs measurement. The measured breathing condition of the user can be sent to the control part 103. In addition, the control part 103 can integrally control the oxygen generating part 101, the breath detection part 201 and the flow regulating part 202, and can also control the control valve 303 of the oxygen storage part 102.

[0079] For example, the user can turn on the oxygen generating switch of the oxygen generating part 101 through the control part 103. The oxygen generated by the oxygen generating part 101 is stored in the oxygen storage part 102, and reaches the breath detection part 201 through the oxygen supply pipe 1021 and the compressible gas storage device 1022. The user can control the breath detection part 201 to perform breath detection through the control part 103, and control the control valve to open and close. The user can also control the flow regulating part 202 through the control part 103 according to the need.

[0080] In some embodiments, the control part 103 is arranged in a wearable device, or the control part 103 is arranged in a mobile terminal, or the control part 103 is arranged in a hanging rope connected to the oxygen supply pipe 1021. The control part 103 is not located on the body of the oxygen generator, which facilitates the user to operate and control.

[0081] For example, the control unit is arranged on a watch, a bracelet or a belt, and the user can operate by raising his hand or lowering his head. The watch or bracelet can also have the function of detecting blood oxygen saturation, and the user can adjust the oxygen flow according to the measured blood oxygen condition.

[0082] For another example, the control unit is arranged on a mobile phone, and no additional display unit is needed. The operation function of the split type oxygen generator of the present application is integrated in the program, and the user can operate in the mobile phone.

[0083] For another example, the control unit is arranged on a mobile phone, and no additional display unit is needed. The operation function of the split type oxygen generator of the present application is integrated in the program, and the user can operate in the mobile phone.

[0084] In the embodiments of the present application, the display unit 203 is arranged on the control unit 103 or the oxygen generating unit 101.

[0085] For example, the display unit 203 is arranged on the control unit 103, and when the user controls the start / stop of the oxygen generating unit, inquires the measurement condition of the respiratory detection unit, or observes the detection result of the flow detection unit, the display unit 203 can display the relevant results. Alternatively, the display unit 203 is arranged on the oxygen generating unit 101 to display the condition of the oxygen generating unit, and the display unit 203 is arranged on the control unit to display the condition of the respiratory detection unit 201 and the flow adjustment unit 202. Alternatively, the display unit 203 is arranged only on the oxygen generating unit 101. The present application does not limit the position of the display unit 203, which can be arranged only in one place or in multiple places. Through the display content of the display unit, the user can more conveniently understand the oxygen use condition and make adaptive adjustment.
