[0019] The beneficial effects of the present invention are as follows:

[0020] 1. By arranging the water vapor separation device, water storage components and electronic sieve oxygen production module from top to bottom, the electrical components are separated from the electrolyte, achieving the effect of dry-wet separation, effectively preventing the electrolyte from wetting the electrical components and damaging them, or preventing the electrical components from being easily damaged by moisture after long-term operation. The overall cascading layout is reasonable, effectively reducing the space occupied by the whole machine, and facilitating related maintenance and repairs; removing the water storage tank can facilitate refilling, and the operation is convenient and quick.

[0021] 2. By integrating the electrolytic oxygen production mechanism into an oxygen production box, the modular setting of the electronic sieve oxygen production module is realized. According to the required oxygen production capacity, it is only necessary to increase or decrease the number of electronic sieve oxygen production modules, and there is no need to move the anode conductive plate and / or the cathode conductive plate, which effectively avoids damage and ensures the oxygen production performance. In addition, in the oxygen production module, there is a composite layer made of polysulfone material on the cathode conductive plate. The characteristics of the polysulfone material are used to achieve a waterproof and breathable effect, ensuring that the oxygen in the air can pass through the composite layer into the oxygen production box and dissolve in the electrolyte, while preventing the electrolyte in the oxygen production box from leaking out of the oxygen production box. The oxygen generator uses oxygen in the air as a raw material, can reliably, effectively and in large quantities absorb oxygen in the air, and can then continuously prepare inhalable pure oxygen. The oxygen production capacity is high, and the purity of the produced oxygen is extremely high, with a purity of more than 99%.

[0022] 3. Several sets of electronic sieve oxygen generation modules can be spliced in sequence to form an electronic sieve oxygen generation module group. The oxygen generation amount can be controlled by simply increasing or decreasing the number of spliced electronic sieve oxygen generation modules, meeting the usage needs of different users and the configuration requirements of different models. The splicing structure between the electronic sieve oxygen generation modules is simple and reasonable, and the performance is reliable, making the overall structure of the electronic sieve oxygen generation module group stable, reliable, and highly integral. The power connection pieces on the electronic sieve oxygen generation modules can be electrically connected to the cathode conductive plates in the next set of electronic sieve oxygen generation modules while the modules are being spliced, thereby enabling the series connection of each electronic sieve oxygen generation module. This allows each electronic sieve oxygen generation module to perform oxygen generation operations simultaneously and synchronously. On the premise of producing the same amount of oxygen, the manufacturing cost of this structure is lower than that of traditional structures. The electronic sieve oxygen generation module group can be assembled with the oxygen generator body as a whole, with convenient and fast operation, facilitating subsequent maintenance work and providing a good user experience.

[0023] 4. Oxygen can complete two-stage separation and one-stage filtration on the water vapor separation box. The two-stage separation system can effectively separate the gaseous electrolyte mixed in the oxygen, and the filtration system can effectively filter oxygen and adsorb impurities. Through two-stage separation and one-stage filtration, the user's usage safety is greatly improved, and the separated electrolyte will automatically flow back to the electrolysis box for recycling, reducing the loss of electrolyte and the frequency of adding electrolyte.

[0024] 5. To improve the comfort of users' oxygen inhalation, humidification is required before oxygen supply. Therefore, there is a humidification and water replenishment device on the water vapor separation box. The oxygen that has completed water vapor separation will be transported to the purified water in the humidification water tank for humidification. In addition, an HP detector is installed in the humidification water tank to continuously monitor the HP value of the purified water in the humidification water tank, thereby monitoring whether any components are malfunctioning. If the HP value is abnormal, the oxygen generator stops working, thus ensuring the user's usage safety.

[0025] 6. The humidification water tank is connected to the water storage tank. When the water level sensor in the water storage tank detects that the water level in the water storage tank is too low, the water replenishment pump works to supplement the liquid in the humidification water tank to the water storage tank, effectively extending the endurance of the oxygen generation work and avoiding the inconvenience of frequent water replenishment for the oxygen generator.

This layout structure can achieve the dry-wet separation of the electrolyte and the control circuit board, effectively preventing the control circuit board from being damaged by liquid;

[0050] The electronic sieve oxygen generation module A' is formed by splicing six sets of electronic sieve oxygen generation modules A at intervals; the electronic sieve oxygen generation module A includes a flat oxygen generation box, an anode conductive plate A3 and two cathode conductive plates A201; there is an oxygen generation chamber A9 for storing electrolyte in the oxygen generation box, the anode conductive plate A3 and the cathode conductive plates A201 are respectively disposed in the oxygen generation chamber A9 and at least partially immersed in the electrolyte, and the two cathode conductive plates A201 are arranged at intervals on both sides of the anode conductive plate A3. The electrolyte is electrolyzed water containing low-concentration sodium hydroxide or potassium hydroxide; waterproof and breathable composite layers A202 are respectively disposed on both sides of the cathode conductive plate A201 to form an oxygen generation membrane A2, so that oxygen in the air can pass through the composite layer A202 into the oxygen generation chamber A9 for the oxygen to be mixed with the electrolyte for dissolved oxygen, and the electrolyte cannot pass through the composite layer A202 and seep out of the oxygen generation chamber A9; most of the sides of the cathode conductive plate A201 provided with the composite layer A202 are exposed outside the oxygen generation box to contact the air to adsorb oxygen in the air; an air outlet channel communicating with the oxygen generation chamber A9 is provided on the oxygen generation box, and the prepared oxygen is transported to the water vapor separation device C through the air outlet channel; the power connection terminal A301 on the anode conductive plate A3 is led out of the oxygen generation box; the anode conductive plate A3 in the upper set of electronic sieve oxygen generation modules A is electrically connected to any one of the cathode conductive plates A201 in the lower set of electronic sieve oxygen generation modules A; the cathode conductive plate A201 on the first set of electronic sieve oxygen generation modules A is electrically connected to the cathode of the power supply, and the anode conductive plate A3 on the last set of electronic sieve oxygen generation modules A is electrically connected to the anode of the power supply; during operation, oxygen in the air passes through the composite layer A202 to reach the surface of the cathode conductive plate A201 with a negative pole, and a dissolved oxygen reaction occurs on the surface of the cathode conductive plate A201 under the action of a direct current electric field, and then a reverse reaction occurs on the anode conductive plate A3 to produce oxygen, and the oxygen is transported to the water vapor separation device C through the air outlet channel;

[0051] The water vapor separation device C includes a water vapor separation box C1. Inside the cavity of the water vapor separation box C1, there is a first-stage separation cavity C1013, a second-stage separation cavity C1015, and a filtration cavity that are connected in sequence. The oxygen coming out of the water storage component B passes through the first-stage separation cavity C1013, the second-stage separation cavity C1015, and the filtration cavity in sequence. In the first-stage separation cavity C1013, several first-stage liquid baffle plates C1014 are arranged in a staggered manner. When the oxygen is transported in the first-stage separation cavity C1013, the entrained water vapor will collide with the first-stage liquid baffle plates C1014, causing the water vapor to adhere to the first-stage liquid baffle plates C1014 and ultimately being recycled. In this stage, the preliminary water vapor separation work can be completed, effectively separating out most of the water vapor and achieving recycling. The water vapor separation box C1 is provided with a refrigeration component C3 corresponding to the second-stage separation cavity C1015. In the second-stage separation cavity C1015, several second-stage liquid baffle plates C1016 are arranged in a staggered manner. When the oxygen is transported in the second-stage separation cavity C1015, the entrained water vapor will collide with the second-stage liquid baffle plates C1016, causing the water vapor to adhere to the second-stage liquid baffle plates C1016. In addition, the refrigeration effect of the refrigeration component can condense the water vapor back to the liquid state and make it adhere to the second-stage liquid baffle plates C1016. The separated electrolyte is ultimately recycled. In this stage, the gaseous water vapor in the oxygen can be effectively separated, further completing the water vapor separation process. The water vapor separation box C1 is provided with a filter box C4 corresponding to the filtration cavity. The gas coming out of the second-stage separation cavity C1015 passes through the filter box C4 unidirectionally. The oxygen that has completed the second-stage separation then enters the filter box C4 for filtration. In this stage, the remaining water vapor in the oxygen can be effectively adsorbed, and the impurities in the oxygen can also be adsorbed, making the finally supplied oxygen highly clean. The water vapor separation box C1 is provided with an intake sleeve C1011 communicating with the first-stage separation cavity C1013 and an outlet joint C1027 communicating with the filtration cavity.

[0057] Further, the electronic sieving oxygen generation module A includes two oxygen generation membranes A2. The cathode conductive plates A201 in the two oxygen generation membranes A2 are electrically connected to each other. The two cathode conductive plates A201 are respectively arranged at intervals on the front side and the rear side of the anode conductive plate A3.

Specifically, the oxygen generation box is provided with conductive columns A8 that are inserted into the front and rear shells at the same time. The conductive columns A8 are respectively electrically connected to the two cathode conductive plates A201 in the same electronic sieving oxygen generation module A and the power connection pieces A6 in the previous set of electronic sieving oxygen generation modules A, so that the power connection pieces A6 in the previous set of electronic sieving oxygen generation modules A are respectively electrically connected to the two cathode conductive plates A201 in the next set of electronic sieving oxygen generation modules A. The front shell A1 is provided with a front avoidance opening A110 at the assembly position corresponding to the conductive column A8, and the rear shell A4 is provided with a rear avoidance opening A410 at the assembly position corresponding to the conductive column A8.

The conductive column A8 is electrically connected to the two cathode conductive plates A201 by plugging.

[0058] Further, there is a module connection sleeve A107 on the front side of the oxygen generation box and a module connection column A407 on the rear side. The module connection sleeve A107 in the previous set of electronic sieving oxygen generation modules A is inserted into the module connection column A407 in the next set of electronic sieving oxygen generation modules A to realize the mutual splicing of two adjacent electronic sieving oxygen generation modules A.

[0059] Furthermore, the bottom surface of the primary separation chamber C1013 is lower than that of the secondary separation chamber C1015, enabling the electrolyte separated in the secondary separation chamber C1015 to flow into the primary separation chamber C1013 along the trend and ultimately return to the water storage tank of the water storage assembly B; one end of the primary separation chamber C1013 is connected to the intake sleeve C1011, and the other end is connected to one end of the secondary separation chamber C1015, ensuring that oxygen can sequentially pass through the primary separation chamber C1013 and the secondary separation chamber C1015 unidirectionally to perform water vapor separation in an orderly manner; the filtration chamber is divided into non-communicating transition chambers C1017, a filtered intake chamber C1018, and a filtered outlet chamber C1019.

Specifically, the bottom surface of the primary separation chamber C1013 is inclined towards the intake sleeve C1011; the bottom surface of the secondary separation chamber C1015 is inclined towards the side connected to the primary separation chamber C1013; the bottom surface of the transition chamber C1017 is inclined towards the side connected to the secondary separation chamber C1015. The above-mentioned inclined bottom surface setting can enable all the electrolyte in each chamber to flow back to drain all the electrolyte, thereby preventing liquid accumulation in the chamber and breeding bacteria.

[0060] Further, the anti-tipping valve C2 includes a control motor C201, a valve seat C202, and a valve core C204.

There is an air delivery channel C2042 on the valve core C204, and a sealing plate C203 closes the top of the air delivery channel C2042. When the valve core C204 rotates to the conducting position, one end of the air delivery channel C2042 communicates with the transition chamber C1017, and the other end communicates with the filtered air intake chamber C1018, that is, the transition chamber C1017 communicates with the filtered air intake chamber C1018 through the air delivery channel C2042. When the valve core C204 rotates to the cut-off position, the air delivery channel C2042 is not connected to the transition chamber C1017 and / or the filtered air intake chamber C1018, that is, the connection between the transition chamber C1017 and the filtered air intake chamber C1018 is disconnected. When the oxygen generator is tipped over, the tipping sensor on the circuit control board issues an instruction, and the anti-tipping valve C2 executes the relevant instruction to cut off the connection between the transition chamber C1017 and the filtered air intake chamber C1018, effectively preventing the electrolyte from flowing back, protecting the circuit and related components on the oxygen generator from being damaged, ensuring the use effect of the oxygen generator, and extending the service life of the oxygen generator. Specifically, a first air hole C1023 communicating with the transition chamber C1017 and a second air hole C1024 communicating with the filtered air intake chamber C1018 are formed at the top of the water-vapor separation box C1. When the valve core C204 rotates to the conducting position, the intake end C2041 of the air delivery channel C2042 corresponds to and communicates with the first air hole C1023, and the outlet end C2043 of the air delivery channel C2042 corresponds to and communicates with the second air hole C1024. When the valve core C204 rotates to the cut-off position, the intake end C2041 of the air delivery channel C2042 is misaligned with the first air hole C1023, and the outlet end C2043 of the air delivery channel C2042 is misaligned with the second air hole C1024. There is a circular valve cavity C2021 in the valve seat C202, and at least part of the valve core C204 is inserted into the valve cavity C2021 with a gap and can rotate in the valve cavity C2021. A conducting limit rib C2022 and a cut-off limit rib C2023 are provided on the inner wall of the valve cavity C2021, and a limit block C2044 is provided on the valve core C204. When the valve core C204 rotates to the conducting position, the conducting limit rib C2022 limits the limit block C2044 to ensure that the valve core C204 accurately rotates to the conducting position. When the valve core C204 rotates to the cut-off position, the cut-off limit rib C2023 limits the limit block C2044 to ensure that the valve core C204 accurately rotates to the cut-off position.

[0061] Further, a filtering air inlet nozzle C1025 communicating with the filtering air inlet chamber C1018 and a filtering air outlet nozzle C1026 communicating with the filtering air outlet chamber C1019 are provided at the top of the water vapor separation box C1; the filtering air inlet C4011 at the bottom of the filtering box C4 is inserted into the filtering air inlet nozzle C1025, and the filtering air outlet C4014 is connected to the filtering air outlet nozzle C1026; there are a number of filtering chambers C4012 in the inner cavity of the filtering box C4, and the number of filtering chambers C4012 are connected end to end. The filtering air inlet C4011 communicates with the first filtering chamber C4012, and the filtering air outlet C4014 communicates with the last filtering chamber C4012, ensuring the one-way transportation of oxygen in the filtering box C4 and maximizing the transportation distance; an activated carbon unit is provided on the filtering chamber C4012. In addition to the activated carbon unit, relevant filtering units can also be provided to filter oxygen and adsorb water vapor; waterproof breathable membranes, such as molecular membranes, are provided on the filtering air inlet C4011 and the filtering air outlet C4014. The waterproof breathable membrane can further screen out the water vapor in the oxygen and achieve a certain water vapor separation effect. The filtering box C4 is assembled by a filtering bottom box C401 and a filtering top cover C402, and the filtering air inlet C4011, the filtering chamber C4012, and the filtering air outlet C4014 are respectively formed on the filtering bottom box C401.

[0062] Further, an intake inner pipe C1012 is arranged at intervals inside the intake sleeve C1011. One end of the intake inner pipe C1012 communicates with the primary separation chamber C1013, and the opening position of this end is higher than the bottom surface of the primary separation chamber C1013. The gap between the intake sleeve C1011 and the intake inner pipe C1012 communicates with the primary separation chamber C1013. During operation, the prepared oxygen can enter the primary separation chamber C1013 from the inner cavity of the intake inner pipe C1012 and the gap between the intake sleeve C1011 and the intake inner pipe C1012, while the separated electrolyte can only flow back through the gap between the intake sleeve C1011 and the intake inner pipe C1012. It can be seen that the backflow of the electrolyte will not affect the normal transportation of oxygen.

[0063] Further, a pressure stabilizing sleeve C1021 communicating with the primary separation chamber C1013 is provided at the top of the water vapor separation box C1. A pressure balance device C6 is inserted into the pressure stabilizing sleeve C1021, and the inner cavity of the pressure balance device C6 communicates with the corresponding chamber; the pressure balance device C6 is made of a soft material, and the inner cavity has a certain elasticity. Specifically, the pressure balance device C6 is arranged in a column shape, and its side wall is provided with retractable wrinkles C6011; when the air pressure in the inner cavity of the water vapor separation box C1 is too high, the wrinkles C6011 on the pressure balance device C6 stretch, and the inner cavity of the pressure balance device C6 increases; when the air pressure in the inner cavity of the water vapor separation box C1 is too low, the wrinkles C6011 on the pressure balance device C6 contract, and the inner cavity of the pressure balance device C6 decreases; through the above corresponding actions of the pressure balance device C6, the air pressure balance in the inner cavity of the water vapor separation box C1 can be effectively guaranteed.

[0064] Furthermore, a passage valve is provided between the water storage tank B1 and the water-vapor separation box C1. The passage valve opens and closes the air outlet B101 on the water storage tank B1 to conduct or cut off the air path between the water storage tank B1 and the water-vapor separation box C1. The passage valve includes a passage upper cover B2 and a rotating body B3. The passage upper cover B2 is fixedly assembled on the top of the water tank B1 by screws (such as snap-fastening, pasting, etc.) and is detachably connected to the water-vapor separation box C1. The water-vapor passage B201 on the passage upper cover B2 corresponds to the air outlet B101 on the top of the water tank B1 up and down. The rotating body B3 is located between the water tank B1 and the passage upper cover B2 and is rotatably arranged on the top of the water tank B1. A valve port B301 is provided on the rotating body B3. The rotation of the rotating body B3 simultaneously drives the valve port B301 to move. When the valve port B301 moves between the water-vapor passage B201 and the air outlet B101, the air path between the water storage tank B1 and the water-vapor separation box C1 is conducted. When the valve port B301 moves out of alignment with the water-vapor passage B201 and the air outlet B101, the air outlet B101 is closed. By setting the passage valve, the opening and closing of the air outlet B101 are effectively controlled. When the oxygen generator is in operation, the valve port B301 is moved to correspond to and communicate with the air outlet B101 and the water-vapor passage B201. When the water storage component B needs to be disassembled for water replenishment or maintenance and repair, the valve port B301 is moved out of alignment with the air outlet B101 and the water-vapor passage B201, which can effectively prevent the water storage component B from leaking. Specifically, a circular rotating groove B102 is formed on the top of the water tank B1, and the air outlet B101 is located inside the rotating groove B102. The rotating body B3 is formed with a circular rotating part B302, and the rotating part B302 is rotatably arranged inside the rotating groove B102. There is a sufficiently small gap between the rotating groove B102 and the rotating part B302. Under the interaction between the rotating groove B102 and the rotating part B302, the rotating body B3 can rotate effectively and the rotation effect is ideal. The valve port B301 is eccentrically arranged on the rotating part B302. When the rotating part B302 rotates, the valve port B301 swings around its axis, and the air outlet B101 and the water-vapor passage B201 are respectively located on the swing track of the valve port B301. A strip-shaped rotating action part B303 extends from one side of the rotating body B3, and a rotating opening B103 is opened on the side of the rotating groove B102. At least part of the rotating action part B303 penetrates through the rotating opening B103 and exposes the passage upper cover B2 and the water tank B1, which is convenient for users to drive the rotation of the rotating body B3 through the rotating action part B303.

[0065] Furthermore, the water vapor separation box C1 is provided with a refrigeration opening C1022 corresponding to the secondary separation cavity C1015 and communicating with the same. The refrigeration component C3 is embedded in the refrigeration opening C1022 so that the refrigeration surface on the refrigeration component C3 extends into the secondary separation cavity C1015. The refrigeration component C3 includes a heat dissipation fan, heat dissipation fins, a semiconductor refrigeration sheet, and a refrigeration bottom plate made of a metal material. The refrigeration bottom plate is fixedly closed on the refrigeration opening C1022. The semiconductor refrigeration sheet is arranged on the refrigeration bottom plate. The heat dissipation fins are located on top of the semiconductor refrigeration sheet. The heat dissipation fan is arranged on the heat dissipation fins.

[0066] A humidification and water replenishing device C5 is arranged on the water vapor separation box C1. The humidification and water replenishing device C5 includes a humidification water tank C502 and a water replenishing pump C504. The humidification water tank C502 is connected to the air outlet joint C1027 through a first conduit C501. The humidification water tank C502 is connected to the water inlet end of the water replenishing pump C504 through a second conduit C503. The water outlet end of the water replenishing pump C504 is connected to the water replenishing joint C1028 on the water vapor separation box C1 through a third conduit C505. The water replenishing joint C1028 is communicated with the water storage tank B1. The oxygen that has completed the water vapor separation treatment in the water vapor separation box C1 enters the humidification water tank C502 through the first conduit C501, and after being humidified by the clean water in the humidification water tank C502, it is discharged from the oxygen supply joint C506 for direct supply to the user. A water level sensor is arranged in the inner cavity of the water storage tank B1. When the water level in the water storage tank is lower than the set value, the water replenishing pump C504 executes relevant instructions to work, extracts the water in the humidification water tank C502, and replenishes it into the water storage tank through the air inlet sleeve C1011. An HP detector is arranged in the humidification water tank C502. When it is detected that the liquid pH value in the humidification water tank C502 is abnormal, the oxygen generator stops working to ensure the safety of the user during use. An oxygen supply joint C506 is arranged on the humidification water tank C502 for supplying oxygen.

[0067] Furthermore, the water vapor separation box C is assembled by a water vapor separation plate C101 and a water vapor separation cover C102.
