[0024] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.
[0026] The directional terms such as up, down, left, right, front, back, inside, outside, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components.
[0027] In addition, the features in the embodiments of the present application may be combined with each other without conflict. In different drawings, the same components are represented by the same reference numerals, and other components are omitted for brevity, but this does not mean that the device for consuming oxygen in the present application may not include other components. It should be understood that the size, proportional relationship and number of components in the drawings are not intended to limit the present application.
[0028] As mentioned above, reducing the oxygen in the storage space used to store food is of great significance for the preservation and long-term storage of food. At present, refrigerators, refrigerators and other equipment are commonly used in households to preserve food. These devices extend the shelf life of food by lowering the temperature, but ignore the oxygen in the storage space. Therefore, food will still be oxidized by oxygen, making it difficult to achieve long-term preservation of food. When food needs to be stored for a long time, vacuum packaging is usually used to physically isolate oxygen to prevent food oxidation. This method is inconvenient to operate and requires additional vacuum packaging equipment, which is not suitable for use in daily household life.
[0029] To this end, an embodiment of the present disclosure proposes a device for consuming oxygen, which includes a deaerator and a water collector. The deaerator is tubular, including an anode, a proton exchange membrane and a cathode stacked in sequence from the inside to the outside. The deaerator can store water from the water collector. After the external power supply is turned on, the cathode and anode of the deaerator can undergo an electrochemical reaction to consume the oxygen in the storage space. The water collector is connected to the deaerator through a pipeline. The water collector can collect moisture in the environment and provide it to the deaerator through the pipeline to replenish the moisture consumed in the electrochemical reaction process in the deaerator.
[0030] Through this structure in which the deaerator and the water collector are connected in series, the water collector can continuously replenish the water consumed by the deaerator in the process of consuming oxygen, so that the electrochemical reaction in the deaerator can proceed stably for a long time. In addition, the cathode where the oxygen consumption reaction occurs is on the outside of the deaerator. Since the deaerator is tubular, the outside of the tube has a larger area than the inside, so the deaerator can consume more oxygen through a larger area, thereby improving the efficiency of the deaerator in consuming oxygen. In the storage space, the device for consuming oxygen provided by the present disclosure can continuously, stably and efficiently consume the oxygen in the storage space, thereby preventing the oxidation of food and effectively extending the shelf life of food.
[0031] The embodiments provided by the present disclosure are schematically described below in conjunction with the accompanying drawings. Figure 1 FIG. 1 is a schematic diagram of an apparatus 100 for consuming oxygen in some embodiments of the present disclosure. Figure 1As shown, the device 100 may include a water collector 101 and a deaerator 102, and the water collector 101 and the deaerator 102 may be connected to each other through a pipe 103. Among them, the water collector 101 is configured to collect moisture in the environment. In some embodiments, the water collector 101 may be a condensation plate that can condense water vapor in the environment into liquid water. In some embodiments, the water collector 101 may be a condensation plate having a plurality of capillaries on the surface. Since the saturated vapor pressure in the capillaries is lower than the saturated vapor pressure of the external environment, water vapor is more likely to condense into liquid water in the capillaries, so that the efficiency of water collection can be improved.
[0032] The deaerator 102 may be a hollow tubular structure, one end of the center of the deaerator 102 may be closed, and the other end may be connected to the pipe 103, so that the pipe 103 can connect the center of the deaerator 102 with the water collector 101. The moisture collected by the water collector 101 can be transported to the center of the deaerator 102 through the pipe 103. In some embodiments, the water collector 101 may be deployed at a level higher than the level of the deaerator 102, so that the moisture collected by the water collector 101 can flow into the center of the deaerator 102 through the pipe 103 by gravity. In some embodiments, a transport device for transporting moisture to the deaerator 102 in one direction, such as a water pump, may be provided in the pipe 103, and the moisture in the water collector 101 can be transported to the deaerator 102 under the action of the transport device.
[0033] Next, combine Figures 2 to 6 , the deaerator 102 in the device 100 in some embodiments of the present disclosure is described. The deaerator 102 may be an electrochemical cell for electrolyzing water, and may include an anode, a proton exchange membrane, and a cathode stacked sequentially from the inside to the outside. Exemplarily, Figure 2 Schematic diagram of the deaerator 102 in some embodiments of the present disclosure is shown. Figure 2 , a longitudinal section 210 and a cross section 220 of the deaerator 102 are also shown. Figure 2 As shown, the anode 201 is on the inner side of the deaerator 102, the cathode 203 is on the outer side of the deaerator 102, and the proton exchange membrane 202 is located between the anode 201 and the cathode 203. The anode 201, the proton exchange membrane 202 and the cathode 203 together constitute the tubular deaerator 102. Both the anode 201 and the cathode 203 can be porous diffusion electrodes, which can include a diffusion layer and a catalyst layer. In some embodiments, the catalyst layer of the anode 201 can include an iridium oxide (IrO2) catalyst, and the catalyst layer of the cathode 203 can include a carbon-supported platinum catalyst (Pt / C).
[0034] The water from the water collector 101 can be stored in the space 214 inside the anode 201 of the deaerator 102, and the water can be in direct contact with the anode 201. The deaerator 102 can be connected to an external power source, and the deaerator 102 can consume the oxygen in the storage space under the power supply of the external power source. The anode 201 of the deaerator 102 can be connected to the positive pole of the external power source, and the cathode 203 can be connected to the negative pole of the external power source. The external power source can provide electrons to the cathode 203, and the anode 201 provides electrons to the external power source. The anode 201 is configured to electrolyze water to produce protons and oxygen. The proton exchange membrane 202 is configured to transport protons from the anode 201 to the cathode 203. The cathode 203 is configured to generate water by reacting protons and oxygen. The chemical reaction formulas of the anode 201 and the cathode 203 can be:
[0035] Anode: 2H2O→O2+4H + +4e - ;
[0036] Cathode: O2+4H + +4e - →2H2O;
[0037] The deaerator 102 consumes oxygen in the storage space outside the cathode 203 through the reaction of the cathode 203, and the anode 201 produces oxygen in this process. In some embodiments, the oxygen produced by the anode 201 can be discharged into the external environment through the pipeline 103. In other words, the pipeline 103 can also connect the deaerator 102 to the external environment. In some embodiments, the water collector 101 can be deployed in an environment different from the storage space where the deaerator 102 is located, so that the oxygen produced in the deaerator 102 can be discharged into the external environment through the water collector 101.
[0038] In an electrochemical cell for electrolyzing water, the oxidation reaction of the electrolyzed water at the anode is usually more intense than the reduction reaction of the generated water at the cathode. In the deaerator with a tubular cell structure in the embodiment of the present disclosure, the anode is located on the inner side of the tube and the cathode is located on the outer side of the tube. Therefore, the cathode has a larger surface area than the anode, so that the reaction of the anode and the cathode can proceed at a more balanced rate. In addition, water can be stored in the tubular cell structure, and the water collector interconnected therewith can also continuously replenish water, thereby maintaining the continuous electrochemical reaction of the deaerator that consumes oxygen.
[0039] It should be understood that Figure 1The device 100 shown is only an illustration of the present disclosure and cannot be a limitation on the technical solution provided by the present disclosure. In some embodiments, in the device 100, the deaerator can also be connected to multiple water collectors through a pipeline at the same time, and moisture from multiple water collectors can be obtained at the same time. In some embodiments, a water collector can be connected to multiple deaerators to provide moisture for multiple deaerators. It should also be understood that in the embodiments of the present disclosure, although the shape of the cross-section of the deaerator 102 is shown as a circle, it is not intended to limit the specific shape of the cross-section of the deaerator 102 provided by the present disclosure. For example, in some embodiments, the deaerator 103 can also be a square tube.
[0040] In some embodiments, the inner side of the deoxidation membrane block 102 may also include a metal tube wall, for example, Figure 3 Reference Figure 3 The anode 201, the proton exchange membrane 202 and the cathode 203 of the deaerator 102 can be sequentially wrapped on the metal tube wall 301. The strength of the deaerator 102 can be improved by the internal metal tube wall 301. In some embodiments, the material of the metal tube wall can be a corrosion-resistant metal, such as titanium, which can maintain normal use for a long time, thereby improving the stability of the deaerator 102.
[0041] The metal tube wall 301 may be in contact with the anode 201 and may include a plurality of holes, which may connect the space 214 for storing water inside the deaerator 102 with the anode 201, so that the anode 201 can be in contact with water, allowing the electrochemical reaction in the deaerator 102 to proceed normally.
[0042] In some embodiments, the anode 201, the proton exchange membrane 202 and the cathode 203 in the deaerator 102 are wrapped in a portion of the axial region of the metal tube wall 301. For example, Figure 4 Reference Figure 4 , the metal tube wall 301 in the deaerator 102 may protrude at one end of the deaerator 102, that is, the length of the anode 201, the proton exchange membrane 202, and the cathode 203 along the axial direction of the deaerator 102 may be shorter than the length of the metal tube wall 301. It should be understood that the portion of the metal tube wall 301 in contact with the anode 201, that is, the portion wrapped by the anode 201, the proton exchange membrane 202, and the cathode 203 may include a plurality of holes for water to pass through, and the other portions of the metal tube wall 301 may be dense and include no holes.
[0043] An anode collector 420 may be disposed on the portion of the metal tube wall 301 not wrapped by the anode 201 . The anode collector 420 may be connected to the positive electrode of the power supply 410 , so that the anode 201 may be connected to the positive electrode of the power supply 410 . The current of the power supply 410 may reach the anode 201 through the anode collector 420 and the metal tube wall 301 .
[0044] In some embodiments, the anode 201, the proton exchange membrane 202 and the cathode 203 are sheets sequentially wrapped on the metal tube wall 301. For example, Figure 5 Reference Figure 5 After the anode 201, the proton exchange membrane 202 and the cathode 203 wrap around the metal tube wall 301, the inner sides of the two ends of the sheet layer can overlap each other and be clamped by the clamping device 505 to form a strip structure protruding on one side of the deaerator 102. In some embodiments, the clamping device 505 is made of a conductive material and contacts the cathode 203. The clamping device 505 can serve as a cathode current collector and connect the negative electrode of the power supply 510, so that the cathode 203 and the negative electrode of the power supply 510 are connected to each other.
[0045] In some embodiments, the outer layer of the cathode 203 of the deaerator 102 may further include a hydrophobic layer to prevent the water inside the deaerator 102 from passing through the anode 201, the proton exchange membrane 202 and the cathode 203 and then being lost from the deaerator 102. Figure 6 Reference Figure 6 The outer layer of the cathode 203 of the deaerator 102 may also be wrapped with a hydrophobic carbon layer 601 and a hydrophobic porous filter layer 602. The hydrophobic carbon layer 601 can enhance the diffusion of external oxygen on the cathode 203 and prevent the water in the deaerator 102 from seeping out. The material of the hydrophobic porous filter layer 602 may be polytetrafluoroethylene (PTFE), which can prevent water from passing through while allowing oxygen to pass through.
[0046] In some embodiments, both ends of the deaerator 102 may further include sealers, which can seal the cross-sections of the anode 201, the proton exchange membrane 202, and the cathode 203 at both ends of the deaerator 102, thereby preventing water in the deaerator 102 from leaking out from both ends. Figure 6 Also shown are sealers 603 and 604 respectively disposed at both ends of the deaerator 102 .
[0047] Combined with the above Figures 2 to 6 The deaerator 102 in the device 100 in some embodiments of the present disclosure is described. Figure 7 The water collector 101 in the device 100 in some embodiments of the present disclosure is described. Figure 7Schematic diagram of the water collector 101 and a cross section 701 of the water collector 101 are shown in FIG. Figure 7 The surface of the water collector 101 may include a plurality of capillary pores 702, the diameter of the capillary pores 702 may be, for example, 4 to 6 nanometers, and the depth of the capillary pores 702 may be, for example, 1 to 2 millimeters. It should be understood that the present disclosure does not limit the specific distribution of the capillary pores on the surface of the water collector.
[0048] In some embodiments, the water collector 101 may be made of a hydrophilic material, which may include but is not limited to polyvinyl alcohol, polyacrylate, silica gel, etc. In some embodiments, the inner wall of the capillary pore 702 may be coated with a hydrophilic material. Through the capillary action of the capillary pore 702 on the water collector 101, the saturated vapor pressure inside the capillary pore 702 will be lower than the saturated vapor pressure outside the capillary pore 702, so that the water vapor will condense into liquid water in the capillary pore 702. This water collection method of the water collector 101 does not need to rely on external energy supply, can save energy, and achieve long-term supply of water.
[0049] In some embodiments, the water collector 101 may further include a plurality of exhaust holes, which are used to discharge the oxygen generated in the deaerator 102. In some embodiments, the diameter of the exhaust hole is greater than the diameter of the capillary pore. In some embodiments, the area ratio occupied by the plurality of capillary pores on the water collector 101 is greater than the area ratio occupied by the plurality of exhaust holes. Since the efficiency of the capillary pores in collecting liquid water is lower than the efficiency of the gas being discharged from the exhaust holes, more capillary pores can be more conducive to improving the water collection efficiency of the water collector 101.
[0050] Figure 8 FIG. 8 is a schematic diagram of an apparatus 800 for consuming oxygen provided by some embodiments of the present disclosure. The apparatus 800 may be an example of the aforementioned apparatus 100. Figure 8 The device 800 may include a water collector 101 and a deaerator 102, and the water collector 101 and the deaerator 102 are connected to each other through a pipe 103. The water collector 101 includes a plurality of capillaries for condensing gaseous water in the environment into liquid water, and a plurality of exhaust holes for exhausting oxygen from the deaerator 102.
[0051] The deaerator 102 includes a porous titanium tube and an anode, a proton exchange membrane, a cathode, a hydrophobic carbon layer and a hydrophobic porous filter layer wrapped in sequence on the titanium tube. The anode, the proton exchange membrane and the cathode are in a lamellar shape and are clamped by a conductive clamping device 505 on both sides. The clamping device is in contact with the cathode and is connected to the negative pole of the power supply 801. One side of the metal titanium tube protrudes from the deaerator 102, and the protruding portion includes an anode current collector 420, which is connected to the positive pole of the power supply 801. In the device 800, the pipeline 103 can be connected to one end of the protruding metal titanium tube in the deaerator 102, or it can be connected to the non-protruding end.
[0052] The device 100 or device 800 provided in the embodiments of the present disclosure may be deployed in a device such as a refrigerator or a locker for storing food or other items. For example, Fig. 9 FIG. 1 is a schematic diagram of a refrigerator 900 provided in some embodiments of the present disclosure. Fig. 9 In the refrigerator 900, a water collector 101 and a deaerator 102 may be included, and the water collector 101 and the deaerator 102 are connected by a pipeline to form the aforementioned device 100 or device 800. The water collector 101 may be deployed on the outer wall of the refrigerator 900, and the water vapor in the environment outside the refrigerator 900 may be condensed into liquid water and provided to the deaerator 102, and the oxygen generated by the deaerator 102 may be discharged outside the refrigerator 900. The deaerator 102 may consume the oxygen in the storage space in the refrigerator 900 through an electrochemical reaction.
[0053] In some embodiments, one end of the deaerator 102 is also connected to an exhaust pipe for discharging the oxygen generated by the deaerator 102 out of the refrigerator 900. That is to say, the water collector 101 does not have to be used to discharge oxygen. The water collector 101 can be deployed in the storage space of the refrigerator 900, so that the water vapor in the storage space can be condensed into liquid water and provided to the deaerator 102. In this way, the moisture in the refrigerator 900 can be removed and the refrigerator 900 can be kept dry.
