DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] Embodiment 1

[0033] like Figure 1-7 As shown, an oxygen production device 10 includes: an electrolytic reaction box and an electrolyte box; the electrolytic reaction box includes: an electrolytic box body 210, an anode component 220 and a cathode component 230.

[0034] The anode component 220 and the cathode component 230 are plate-like components. The cathode component 230 is installed in the cavity structure to divide the cavity structure into two parts. The part located on one side of the cathode component 230 is the reaction chamber 211, and the part located on the other side is the air inlet chamber 212; the anode component 220 is installed in the reaction chamber 211; the reaction chamber 211 and the air inlet chamber 212 are distributed in parallel on both sides of the cathode component 230, and the periphery of the cathode component 230 is tightly attached to the cavity structure and sealed with a sealing material; the anode component 220 is connected to the positive pole of the power supply wire; the cathode component 230 is connected to the negative pole of the power supply wire.

[0035] The top surface of the electrolytic box body 210 is vertically provided with a liquid inlet 213; the top surface of the electrolytic box body 210 is vertically protruded with an exhaust pipe 270 and a buckle 280; the liquid inlet 213 and the exhaust pipe 270 are connected to the reaction chamber 211; the liquid inlet 213 is provided with a protrusion 240.

[0036] The electrolyte box includes: a liquid storage box body 110 and a sealing membrane 120; the vertical side wall of the liquid storage box body 110 is provided with a limiting recess 130; the bottom of the liquid storage box body 110 is vertically provided with a liquid outlet 112 and a connecting port 111; the sealing membrane 120 is detachably sealed and arranged on the liquid outlet 112 and the connecting port 111.

[0037] When the liquid inlet 213 of the electrolytic reaction box is connected to the liquid outlet 112, the exhaust pipe 270 and the buckle portion 280 are vertically inserted into the limiting recessed portion 130 at the corresponding position; the raised portion 240 punctures the sealing film.

[0038] The sealing membrane 120 may specifically be a thin film material bonded to the liquid outlet 112 or the communication port 111 , and may be torn off from the liquid outlet 112 or the communication port 111 , or directly punctured, under the action of an external force.

[0039] The electrolyte box is provided with a liquid outlet 112, which is an opening structure for the electrolyte to flow out of the electrolytic reaction box. The connecting port 111 connects the electrolyte box with the external interface, which can avoid the negative pressure generated inside the electrolyte box after the electrolyte flows out. The air pressure in the electrolyte box is kept equal to the external air pressure, so that the electrolyte flows out more smoothly. The main function of the electrolyte box is to continuously provide a sufficient amount of electrolyte to the oxygen generator 10. The electrolyte box can be sold and transported as an independent commodity in the market. When the electrolyte box is filled with electrolyte, the electrolyte is easy to leak out during the sales, storage and transportation process. Therefore, the liquid outlet 112 and the connecting port 111 need to be sealed.

[0040] It should be noted that when the oxygen production device 10 is implemented with the above structure, oxygen is produced by electrolysis using the technical principle of electrochemical oxygen production by air electrodes in the prior art. The cathode member 230 is specifically an air electrode in the prior art, which is generally composed of a hydrophobic air-permeable layer, a porous catalytic layer, and a metal matrix conductive mesh. The hydrophobic air-permeable layer may be a porous structure composed of polytetrafluoroethylene, which allows gas to enter the interior of the electrode and prevents the electrolyte from leaking out of the hydrophobic air-permeable layer.

[0041] The anode member 220 can be made of a metallic conductive material that is insoluble in the electrolyte.

[0042] The technical principle of electrochemical oxygen production by air electrodes in the prior art can be summarized as follows: oxygen in the air reacts at the cathode to generate OH - or HO2 - Ion, OH - or HO2 - Under the action of electric field force, ions diffuse and move to the anode, where the following reactions occur:

[0043] 4OH — 4e→2H2O+O2(pure)↑

[0044] OH — +HO2 - →H2O+O2(pure)↑.

[0045] In this embodiment, the electrolysis box body 210 cleverly uses the cathode member 230 as a partition structure in the cavity structure, and obtains the reaction chamber 211 and the air chamber for electrolytic oxygen production using the technical principle of air electrode electrochemical oxygen production; the structure in the electrolysis box body 210 is simple, the production is convenient, and the manufacturing cost is low; and the contact area between the anode member 220 and the cathode member 230 and the electrolyte is larger, and the other side of the cathode member 230 can fully contact with the air, which can greatly improve the efficiency of electrolytic oxygen production.

[0046] One side of the reaction chamber 211 is recessed outwardly to form a mounting groove 222, which is connected to the outside of the electrolytic box body 210; one end of the anode member 220 is inserted into the mounting groove 222 and connected to the external power supply wire, and the mounting groove 222 is filled with a sealing material, which can be epoxy resin.

[0047] One side of the cathode member 230 is in contact with the air, so one side of the cathode member 230 is exposed outside the reaction chamber 211. The connection operation between the cathode member 230 and the power supply wire is very simple, while the anode member 220 is located inside the electrolyte. It is necessary to connect it with the power supply wire and ensure the sealing of the reaction chamber 211 to prevent the electrolyte from leaking out. Connecting the power supply wire in the installation groove 222 and then filling the sealing material can well solve the technical contradiction between the connection between the cathode member 230 and the power supply wire and the sealing of the reaction chamber 211, and the production operation is simple and convenient.

[0048] The side wall of the air inlet cavity 212 facing the cathode component 230 is an air inlet cover plate 2121, which is provided with a plurality of air inlet holes 2122. The air inlet cover plate 2121 is detachably mounted on one side of the air inlet cavity 212; specifically, the air inlet cover plate 2121 is mounted on the air inlet cavity 212 via a snap-fit ​​structure.

[0049] The air inlet cover plate 2121 is provided with an air inlet hole 2122 to allow air outside the oxygen generator 10 to smoothly enter the air inlet cavity 212 , so that the side wall of the cathode component 230 located in the air inlet cavity 212 is fully in contact with the air.

[0050] The electrolytic box body 210 is provided with a liquid inlet chamber 260; the liquid inlet chamber 260 is located on one side of the reaction chamber 211, away from and facing the cathode member 230; a liquid inlet port 213 is provided on the top of the liquid inlet chamber 260, and a liquid outlet hole 261 is provided horizontally or obliquely upward on the vertical side wall of the liquid inlet chamber 260, and the liquid outlet hole 261 is used to connect the liquid inlet chamber 260 with the reaction chamber 211.

[0051] When the electrolysis reaction is carried out in the reaction chamber 211, oxygen will be generated. Under the action of buoyancy, the oxygen will float upward in the electrolyte; the liquid outlet 261 is an opening structure that connects the reaction chamber 211 with the liquid inlet chamber 260. If it is set vertically or tilted downward, the oxygen in the reaction chamber 211 will easily enter the liquid inlet chamber 260 from the liquid outlet 261, and then enter the liquid storage chamber, and finally directly enter the external air, while the exhaust port 214 cannot normally output oxygen, making the oxygen production effect of the oxygen production equipment unsatisfactory. The liquid inlet chamber 260 changes the flow direction of the electrolyte flowing out of the liquid outlet chamber from the vertical direction to the horizontal direction. The liquid outlet 261 is horizontally or tilted upwardly opened on the vertical side wall of the liquid inlet chamber 260, which can prevent the oxygen generated in the reaction chamber 211 from entering the liquid inlet chamber 260, but enters the exhaust pipe 270 vertically upward, and finally outputs from the exhaust port 214. At the same time, it will not hinder the normal flow of the electrolyte, thereby improving the oxygen production effect of the oxygen production device 10.

[0052] A groove structure is provided around the liquid inlet 213, which is annular and has a seal 250 inside. The liquid inlet 213 is provided with a fixed pressure ring 251, which is detachably installed on the liquid inlet 213 and is used to press and fix the seal 250 on the liquid inlet 213.

[0053] The groove structure makes the installation of the seal 250 more convenient and the positioning more precise. The groove structure and the fixed pressure ring 251 can stably install the seal 250 in the liquid inlet 213, thereby ensuring the sealing when the liquid inlet 213 and the liquid outlet 112 are connected; the seal 250 can specifically be a sealing ring made of rubber material.

[0054] The exhaust pipe 270 is located at one side of the reaction chamber 211, away from and facing the cathode member 230; the positive electrode member is arranged close to the side of the reaction chamber 211 away from and facing the cathode member 230; a notch portion 221 is provided at the joint between the positive electrode member and the top surface of the reaction chamber 211; an exhaust port 214 is provided at the top of the exhaust pipe 270, and the bottom of the exhaust pipe 270 is connected to the reaction chamber 211 through the notch portion 221.

[0055] When the anode member 220 and the cathode member 230 are arranged opposite to each other, the contact area with the electrolyte is larger, which can increase the electrolytic reaction speed of the two. However, oxygen is mainly generated on the anode member 220. If the anode member 220 is also completely set as a vertical side wall of the reaction chamber 211 like the cathode member 230, then the oxygen generated on the anode member 220 needs to be first released from the anode member 220 to the electrolyte, and then discharged from the exhaust port 214 at the top of the reaction chamber 211, which will make the discharge of oxygen not smooth enough and even enter the liquid storage chamber; therefore, a notch portion 221 is provided at the position where the top of the anode member 220 and the top surface of the reaction member are in contact, so that the oxygen on the anode member 220 can quickly flow along the anode member 220 to the notch portion 221, and then enter the exhaust pipe 270, and finally be discharged from the exhaust port 214.

[0056] The exhaust pipe 270 and the handle 280 are respectively located on the opposite sides of the electrolytic box body 210; the limiting recess 130 includes a first recess 131 and a second recess 132; the first recess 131 and the second recess 132 are respectively located on the opposite sides of the liquid storage box body 110, and the position of the first recess 131 corresponds to the position of the exhaust pipe 270, and the position of the second recess 132 corresponds to the position of the handle 280.

[0057] When the electrolytic box body 210 is docked with the liquid storage box body 110, the first recessed portion 131 and the second recessed portion 132 provided on the liquid storage box body 110 can slide in the vertical direction close to the exhaust pipe 270 and the buckle portion 280 respectively. The liquid storage box body 110 and the electrolyte box body 210 cannot rotate relative to each other and can only move vertically. At this time, the liquid inlet 213 and the liquid outlet 112 are also directly opposite to each other in the vertical direction. It is only necessary to continue to bring the two together and close together in the vertical direction to quickly complete the docking operation between the two; when the electrolytic box body 210 and the liquid storage box body 110 are docked or disassembled, the exhaust pipe 270, the buckle portion 280, the first recessed portion 131 and the second recessed portion 132 form a guiding and limiting structure on both sides, making the docking or disassembly operation more convenient and quick.

[0058] An exhaust port 214 is provided at the top of the exhaust pipe 270, and the exhaust port 214 is provided with a sealing cover 272, and the sealing cover 272 is provided with a pipe joint 273; the sealing cover 272 is sealed and set at the exhaust port 214 through a snap-on structure; a sealing ring can also be added to the joint position of the sealing cover 272 and the exhaust port 214 for sealing.

[0059] The pipe joint 273 facilitates the connection between the exhaust port 214 and the external pipe, and the installation using a snap-fit ​​structure can make the sealing cover 272 more convenient and quick to operate when assembling or disassembling the exhaust port 214 .

[0060] A convex ridge 274 is provided on the vertical side surface where the exhaust pipe 270 is in contact with the first recessed portion 131; when the liquid inlet 213 of the electrolysis reaction box is connected with the liquid outlet 112, the convex ridge 274 is in close contact with the vertical side surface of the first recessed portion 131; a hollow gap is left between the vertical side surface of the exhaust pipe 270 and the vertical side surface of the first recessed portion 131, so that the exhaust pipe 270 and the sealing cover 272 are embedded in the first recessed portion 131.

[0061] The sealing cover 272 is installed on the exhaust pipe 270 by adopting a snap-fit ​​structure, and the snap-fit ​​structure is located outside the exhaust pipe 270. As a result, the side of the exhaust pipe 270 cannot be stably installed in close contact with the vertical side of the first recessed portion 131, and the limiting effect of the limiting structure cannot be guaranteed; after the convex ridge portion 274 is added to the outside of the exhaust pipe 270, the convex ridge portion 274 can stably fit the vertical side of the first recessed portion 131, and at the same time, the exhaust pipe 270 and the sealing cover 272 can be accommodated in the first recessed portion 131, thereby ensuring the limiting effect of the limiting structure; in addition, the convex ridge portion 274 can also strengthen the vertical side wall of the exhaust pipe 270 to prevent it from being easily damaged due to excessive extension; of course, in order to further improve the connection strength at the connection between the bottom of the exhaust pipe 270 and the reaction chamber 211, reinforcing ribs 275 can also be added there to enhance the structural strength.

[0062] The vertical side of the buckle portion 280 is provided with a hollow portion 281 or a recessed structure, and when the liquid inlet 213 of the electrolytic reaction box is connected with the liquid outlet 112, the buckle portion 280 is tightly attached to the second recessed portion 132, and the hollow portion 281 or the recessed structure is exposed to the outside of the second recessed portion 132.

[0063] In addition to the function of limiting the wire, the buckle portion 280 facilitates the operator to apply force to the electrolytic box body 210 when the electrolytic box body 210 and the liquid storage box body 110 are docked, so that the operator can more easily separate or dock the two.

[0064] The electrolytic box body 210 is provided with an exhaust pipe 270; an exhaust port 214 is provided at the top of the exhaust pipe 270, and the bottom of the exhaust pipe 270 is connected to the reaction chamber 211; a waterproof and breathable membrane 271 is provided inside the exhaust pipe 270, and the waterproof and breathable membrane 271 is used to prevent the electrolyte from being discharged from the exhaust pipe 270, and the waterproof and breathable membrane 271 is used to filter and remove the electrolyte in the gas flowing through the exhaust pipe. Specifically, Figure 5 and 6 As shown, the waterproof and breathable membrane 271 is fixed on the cross section of the exhaust pipe 270 by bracket structures arranged vertically opposite to each other, forming a layered structure that can filter oxygen flowing through the exhaust pipe 270.

[0065] When the oxygen generated in the reaction chamber 211 enters the exhaust pipe 270, it often carries a certain amount of vaporized electrolyte. If the oxygen carries the electrolyte and is discharged from the exhaust port 214, on the one hand, the electrolyte will be consumed too quickly, the oxygen production cost of the oxygen generator 10 will increase, and the electrolyte box replacement operation will be too frequent; on the other hand, the oxygen generator 10 is applied to the air conditioner indoor unit 20, and the air blown out by the air conditioner indoor unit 20 will also contain electrolyte components, causing indoor air to be polluted; after the waterproof and breathable membrane 271 is added to the exhaust pipe 270, the waterproof and breathable membrane 271 can filter the vaporized electrolyte and other substances in the oxygen flowing through, so that the oxygen discharged from the exhaust port 214 is cleaner; in addition, after the electrolyte attached to the surface of the waterproof and breathable membrane 271 reaches a certain concentration, it will flow back into the reaction chamber 211, which also reduces the consumption of electrolysis and reduces the oxygen production cost.

[0066] It should be noted that the waterproof and breathable membrane 271 is an existing membrane material, and its specific implementation methods are varied. It can allow air to pass through while filtering and removing vaporized electrolyte in the air.

[0067] Similarly, a structure for absorbing and recovering the vaporized electrolyte may be provided outside the exhaust port 214, such as Figure 1-3 As shown, an exhaust port 214 is provided at the top of the exhaust pipe 270, and the bottom of the exhaust pipe 270 is connected to the reaction chamber 211; the exhaust port 214 is connected to the adsorption reflux component 30; the adsorption reflux component 30 includes: an adsorption box 31, an input pipe 32, a return liquid pipe 33 and a gas supply pipe 34; the adsorption box 31 is filled with activated carbon, the output end of the input pipe 32 is connected to the input end at the top of the adsorption box 31, and the input end of the input pipe 32 is connected to the exhaust port 214; the input end of the return liquid pipe 33 is connected to the discharge end at the bottom of the adsorption box 31, and the output end of the return liquid pipe 33 is connected to the reaction chamber 211; the gas supply pipe 34 is connected to the exhaust end at the top of the adsorption box 31, and is used to output the gas in the adsorption box 31. The activated carbon in the adsorption box 31 can adsorb substances such as vaporized electrolyte in the oxygen flowing through, so that the oxygen discharged from the gas pipe 34 is cleaner; in addition, after the activated carbon adsorbs the vaporized electrolyte, the adsorbed electrolyte flows back to the reaction chamber 211 through the return pipe 33, which also reduces the consumption of electrolysis and reduces the cost of oxygen production.

[0068] It should be noted that the implementation of providing a waterproof and breathable membrane 271 in the above-mentioned exhaust pipe 270 and the implementation of connecting the adsorption reflux component 30 to the outside of the exhaust port 214 are preferred implementations and can be applied or not applied according to actual conditions; in order to reduce or even avoid the discharge of vaporized electrolyte along with oxygen, those skilled in the art can also select any one of them or implement both implementations at the same time as needed.

[0069] The sealing membrane 120 allows the electrolyte box to maintain a stable sealing state during transportation and storage, thereby preventing leakage of electrolyte. When the electrolyte box is installed on the oxygen generator 10 for use, the sealing membranes on the liquid outlet 112 and the connecting port 111 can be directly removed or punctured. Compared with other existing sealing structures, the sealing membrane 120 at the liquid outlet 112 can also be punctured synchronously during the operation of docking the electrolyte box with the electrolytic reaction box, so that the electrolyte box does not need to be turned over during the installation process, and leakage of electrolyte can be avoided. The electrolyte box has a simple structure, low production and application costs, and can greatly facilitate the assembly and replacement operations of the electrolyte box, so that the oxygen generator 10 can be better applied to air-conditioning products.

[0070] The electrolytic box body 210 cleverly uses the cathode member 230 as a partition structure within the cavity structure, thereby obtaining a reaction chamber 211 and an air chamber for electrolytic oxygen production based on the technical principle of electrochemical oxygen production using air electrodes; the structure within the electrolytic box body 210 is simple, production is convenient, and manufacturing cost is low; and the contact area between the anode member 220 and the cathode member 230 and the electrolyte is larger, and the other side of the cathode member 230 can fully contact the air, which can greatly improve the efficiency of electrolytic oxygen production.

[0071] When the oxygen generator 10 is assembled, the electrolyte box is docked with the electrolysis reaction box from top to bottom in the vertical direction, the liquid outlet 112 is inserted into the liquid inlet 213, and the exhaust pipe 270 and the buckle hand portion 280 are inserted into the limiting recessed portion in the vertical direction; after the electrolyte box and the electrolysis reaction box are docked and assembled, the liquid inlet 213 and the liquid outlet 112 are limited on the docking surface, and the exhaust pipe 270 and the buckle hand portion 280 are limited by the limiting recessed portion, so that the electrolyte box is installed on the docking surface without any limit, the oxygen generator 10 is more convenient to assemble and disassemble, the structure is more stable, and it can be better installed and applied on the oxygen-generating air conditioner.

[0072] Implementation II

[0073] like Figure 8 As shown, an electrolyte box is different from the electrolyte box in the first embodiment in that the liquid storage box body 110 is composed of a concave cavity 114 and a top cover 113. The liquid outlet 112 is arranged at the bottom of the concave cavity 114, and the communication port 111 is arranged on the top surface or side edge of the top cover 113.

[0074] When the electrolyte box is a split structure, its top cover 113 can be detached from the concave cavity 114, which is more convenient for adding electrolyte into the electrolyte box or cleaning the electrolyte box; during the production process, the production cost of the split structure electrolyte box is also lower than that of the integrated structure electrolyte box.

[0075] Because when the electrolyte box is used on the oxygen generator 10, the electrolyte box flows out under the action of gravity, so the liquid outlet 112 at the bottom of the concave cavity 114 can make the electrolyte flow out more smoothly, and the connecting port 111 needs to be connected to the external air to prevent the electrolyte from flowing out. Therefore, according to the specific orientation of the electrolyte box installed on the oxygen generator 10, an electrolyte box with a connecting port 111 on the top surface or side edge can be flexibly selected.

[0076] Embodiment 3

[0077] An oxygen-generating air conditioner comprises: an air conditioner indoor unit 20 and the oxygen-generating device 10 as described in the first embodiment; an exhaust port 214 of the oxygen-generating device 10 extends to an air outlet 21 of the air conditioner indoor unit 20 .

[0078] It should be noted that there are many specific implementation methods for extending the exhaust port 214 to the air conditioner 20, such as using a pipe connection, one end of the pipe is connected to the exhaust port 214, and the other end of the pipe is connected to the air outlet 21 of the air conditioner 20; when the oxygen generator 10 is integrated into the air conditioner 20, the distance between the electrolytic reaction box and the air outlet 21 of the air conditioner 20 is very close, and the exhaust port 214 of the electrolytic reaction box can also be directly extended into the air outlet 21 of the air conditioner. Fig. 9 and 10 As shown, the exhaust port 214 of the electrolysis reaction box is connected to the adsorption reflux component 30, and the output end of the air supply pipe 34 in the adsorption reflux component 30 extends to the air outlet 21 of the air conditioner indoor unit 20, which is used to transport the oxygen produced by the oxygen production device 10 to the air outlet 21 of the air conditioner indoor unit 20.

[0081] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0082] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0083] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
