Description

Technical Field

[0001] This application belongs to the field of air purification technology, specifically relating to a portable negative oxygen ion generator. Background Technology

[0002] Negative oxygen ions are known as "air vitamins" because they can settle particulate matter, neutralize static electricity, and improve sleep. With societal progress, air purifiers that output negative oxygen ions are receiving increasing attention.

[0003] Patent application number "202120233689.9" discloses an air purifier, including a housing, a polarizing electrode, a water tank, and a fan. The housing includes a shell and an openable cover installed within it. The water tank and fan are located inside the shell. The polarizing electrode is placed in the water tank and submerged in water. An air inlet pipe and an air outlet pipe are provided in the water tank. The fan's outlet is connected to the air inlet pipe. The housing has an air inlet corresponding to the air inlet pipe and an air outlet corresponding to the air outlet pipe. However, this structure has a relatively small coverage area for outputting negative oxygen ions. Users need to constantly move the device to achieve the desired negative oxygen ion output in a larger space.

[0004] Therefore, how to provide a portable negative oxygen ion generator with a wide coverage area has become an urgent problem to be solved. Summary of the Invention

[0005] To address the problems existing in the prior art, this application provides a portable negative ion generator. The portable negative ion generator produces negative ions through an electrolysis module, and achieves wider coverage of the space through the synergistic action of the nozzle and the first drive module. This reduces the need for users to move around when performing deodorization and disinfection operations in large spaces, thus ensuring a better user experience.

[0006] To address the above problems, this application provides the following technical solution:

[0007] A portable negative oxygen ion generator includes an electrolysis module and a water tank and a nozzle arranged in series. The electrolysis module is located upstream of the nozzle, and the water flow treated by the electrolysis module is delivered to the nozzle.

[0008] It also includes a first drive module, which is provided with an air inlet and an air outlet, and the nozzle is disposed on the air outlet path downstream of the air inlet.

[0009] This application prepares negative oxygen ions by treating water using an electrolysis module. During the preparation process, no byproducts such as nitrogen oxides that consume negative oxygen ions are generated, and the negative oxygen ions can theoretically diffuse over long distances. However, without nozzles and a first drive module, the actual coverage area of ​​the water flow output from the electrolysis module is still relatively small, which cannot meet the needs of users requiring larger coverage areas. This has led those skilled in the art to form the technical bias that "the amount of negative oxygen ions prepared by electrolyzing water cannot meet user needs."

[0010] This application achieves a significant expansion of the coverage range of negative oxygen ions output through the nozzle by the synergistic effect of the nozzle and the first drive module. Users can achieve coverage of negative oxygen ions in a larger space with a small distance, thereby achieving disinfection and deodorization treatment in a larger space. Therefore, it has significant beneficial effects.

[0011] Furthermore, an impeller is provided at the air outlet of the first drive module, and the nozzle is located downstream of the air outlet of the first drive module.

[0012] Furthermore, the first drive module is a bladeless fan, and the nozzle is disposed in the hollow area of ​​the bladeless fan or downstream of the air outlet of the bladeless fan.

[0013] Furthermore, the electrolysis space of the electrolysis module includes a cathode chamber with a cathode and an anode chamber with an anode, and the cathode chamber and the anode chamber are connected.

[0014] The electrolysis module is directly installed inside the water tank and / or installed on the pipeline connecting the water tank and the nozzle.

[0015] Furthermore, the electrolysis space is divided into a cathode chamber and an anode chamber by a first partition, and a connection port connecting the cathode chamber and the anode chamber is provided through the first partition. Alternatively, a first gap is provided between the first partition and the peripheral wall of the electrolysis space, and the first gap connects the cathode chamber and the anode chamber.

[0016] Furthermore, the electrolysis space of the electrolysis module is divided into a cathode chamber with a cathode and an anode chamber with an anode by a first partition, and the water inlet and outlet of the electrolysis space are both located in the anode chamber;

[0017] The cathode chamber is provided with a hydrogen outlet, which connects the cathode chamber to the outside of the anode chamber.

[0018] The first separator is equipped with a gas check structure.

[0019] Furthermore, the electrolysis module is installed on the pipeline connecting the water tank and the nozzle.

[0020] Furthermore, the electrolysis space of the electrolysis module is divided into a cathode chamber with a cathode and an anode chamber with an anode by a first partition. Both the cathode chamber and the anode chamber are provided with an inlet and an outlet.

[0021] The nozzle is located downstream of the outlet of the anode chamber.

[0022] Furthermore, the water tank is provided with at least one movable part for adjusting the volume of the water tank. When the movable part is in the initial position, the water tank is in the maximum volume state.

[0023] Furthermore, a second drive module is provided on the side of the movable part away from the water flow, and the movable part moves accordingly when the second drive module is working.

[0024] Alternatively, a water suction module may be provided on the outlet side of the water tank, and the movable part may move accordingly when the water suction module is in operation.

[0025] Since negative oxygen ions are generated through an electrolysis module, if the water flow is not delivered to the electrolysis module in a timely manner, there is a possibility that the electrolysis module may dry out, thus shortening its lifespan. For example, when water is pumped from the water tank through a water pump and suction pipe, the suction port of the suction pipe needs to be submerged in water. If the user changes the angle of use, the suction port may be exposed above the water surface, drawing in air instead of water from the tank. This results in insufficient water flow from the pump, ultimately causing the electrolysis module to dry out.

[0026] This application incorporates a movable part, ensuring that the water in the tank is always kept full, thus allowing the water to be delivered to the electrolysis module in a timely manner and preventing the electrolysis module from burning out.

[0027] After adopting the above technical solution, this application has the following beneficial effects:

[0028] 1. The portable negative oxygen ion generator described in this application, on the one hand, produces negative oxygen ions through an electrolysis module, avoiding the generation of accompanying products such as nitrogen oxides that consume negative oxygen ions; on the other hand, through the synergistic effect of the nozzle and the first driving module, it achieves the coverage of negative oxygen ions over a larger space. This overcomes the technical bias in the prior art that "the amount of negative oxygen ions generated by electrolysis of water is too low to meet user needs," and has significant beneficial effects and economic value.

[0029] 2. The portable negative oxygen ion generator described in this application has a movable part at the water tank to adjust the volume of the water tank, so that the water in the water tank is always kept full of the current volume of the water tank, so that it can be smoothly transported to the electrolysis module to participate in electrolysis, thereby avoiding the situation of the electrolysis module burning dry.

[0030] 3. The portable negative oxygen ion generator described in this application uses an electrolysis module whose electrolysis space is divided into a cathode chamber and an anode chamber by a first separator. Under the blocking effect of the first separator, compared with the case where the cathode chamber and the anode chamber are completely connected, the amount of negative oxygen ions carried in the water flow output through the nozzle is further increased in this structural form.

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0043] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] In existing technologies, equipment for producing negative oxygen ions generally uses corona discharge or high-voltage electric field technology to generate negative oxygen ions. However, this structure inevitably generates byproducts such as ozone and nitrogen oxides. Due to the consumption of negative oxygen ions by these byproducts, the electrode area also needs to be increased if more negative oxygen ions are to be output. Therefore, the output efficiency of negative oxygen ions and the miniaturization of the equipment cannot be achieved simultaneously with this structure.

[0045] To overcome the above situation, existing technologies have been developed to produce negative oxygen ions through water electrolysis. However, the actual amount of negative oxygen ions produced is relatively small. If negative oxygen ions need to be produced in a large space, users need to constantly move the equipment, which places a heavy burden on users.

[0046] In view of this, such as Figure 1-7 As shown, this application provides a portable negative oxygen ion generator, which users can hold and use to disinfect and deodorize environments such as home spaces and car interiors by using the negative oxygen ions it outputs.

[0047] Specifically, the portable negative oxygen ion generator of this application includes an electrolysis module 4 and a water tank 1 and a nozzle 2 connected in series. The electrolysis module 4 is located upstream of the nozzle 2 to electrolyze the water in the water tank 1. The water flow after being treated by the electrolysis module is transported to the nozzle 2 and finally atomized and sprayed out to expand the coverage area.

[0048] Regarding the location of the electrolysis module, it can be placed inside the water tank 1, or it can be placed on the pipeline connecting the water tank 1 and the nozzle 2. In this structure, the water tank 1, the electrolysis module 4 and the nozzle 2 are connected in series.

[0049] In order to improve the output efficiency of negative oxygen ions under the premise of generating negative oxygen ions by electrolysis of water, the portable negative oxygen ion generator of this application is also provided with a first driving module 3. The first driving module 3 is provided with an air inlet 31 and an air outlet 32, and the nozzle 2 is provided on the air outlet path downstream of the air inlet 31.

[0050] In one embodiment of this application, such as Figure 1 As shown, an impeller is provided at the air outlet 32 ​​of the first drive module 3. In this structure, the nozzle 2 is located downstream of the air outlet 32 ​​of the first drive module 3. After the water treated by the electrolysis module is atomized and sprayed out through the nozzle 2, it can be diffused to a larger range under the action of the first drive module 3, thereby achieving coverage of a larger space and facilitating user operation.

[0051] In another embodiment of this application, such as Figure 2 As shown, the first drive module 3 is a bladeless fan with a hollow area. In this embodiment, one end of the hollow area is the air inlet 31, and the other end is the air outlet 32. Due to the hollow area, the nozzle 2 can be located downstream of the air outlet 32 ​​or directly within the hollow area. The air entering the hollow area through the air inlet 31 drives the atomized water flow sprayed from the nozzle 2 to be output through the air outlet 32. At this time, it can still play an auxiliary diffusion role for this part of the atomized water flow.

[0052] Regarding the structure of nozzle 2, in one embodiment of this application, a third drive module in the form of an air pump or the like can be provided. The output end of the third drive module, the outlet 47 of the electrolysis module 4 and the nozzle 2 are connected by a three-way valve. The water flow processed by the electrolysis module 4 and the gas output by the third drive module converge in front of the nozzle 2. Then, the water flow output by the nozzle 2 can be dispersed by the air, thus achieving the atomization effect.

[0053] Alternatively, if the third drive module is not set, the nozzle 2 can be set as a variable diameter structure, with its size gradually decreasing along the output direction of the water flow. During the output process of the water flow, as the flow channel decreases, the water flow velocity increases. After being output through the nozzle 2, the water is sheared by the outside air to achieve the atomization effect.

[0054] In one embodiment of this application, in order to reduce the size of the equipment, the water in the water tank 1 can be directly pumped to the electrolysis module 4 through the third drive module.

[0055] Specifically, in addition to the first output end for atomizing the water flow processed by the electrolysis module 4, the third drive module is also equipped with a second output end for pumping the water flow in the water tank 1. The second output end is connected to the water tank 1. As the third drive module pumps outside air into the water tank 1, the water flow in the water tank 1 is squeezed out through the water suction pipe and finally pumped into the electrolysis module 4.

[0056] However, in the above embodiments, if the user inverts the water tank 1 in some usage scenarios, the water inlet of the water suction pipe inside the water tank 1 will be exposed above the water surface. Even if the third drive module is still in working state, the air pumped into the water tank 1 will be directly output through the water suction pipe. At this time, the water suction pipe is transporting the air pumped into the water tank 1 by the third drive module, and it cannot realize the function of transferring water flow to the electrolysis module 4. The electrolysis module 4 may be dry-burning.

[0057] Therefore, in one embodiment of this application, the water tank 1 is provided with at least one movable part for adjusting the volume of the water tank 1. When the movable part is in the initial position, the water tank 1 is in the maximum volume state.

[0058] As the movable part moves, the volume of water tank 1 gradually decreases, thereby ensuring that the water volume in water tank 1 is always kept full to avoid the situation of dry burning of electrolysis module 4.

[0059] Specifically, a second drive module can be provided on the side of the movable part away from the water flow. By pushing the movable part, the volume of the water tank 1 is reduced, thereby squeezing the water inside into the electrolysis module 4 to participate in electrolysis. At this time, the second drive module can be in the form of a push rod, and the movable part can be set as a piston that is sealed to the periphery of the water tank 1. Alternatively, the second drive module can be set as an air pump that does not directly contact the movable part, and the displacement of the movable part can be controlled by adjusting the air pressure.

[0060] Alternatively, the water tank 1 can be configured as a spring bottle. In this configuration, a water pump or similar suction module needs to be installed on the outlet side of the water tank 1 to pump the water in the water tank 1 to the electrolysis module 4. When the water level in the water tank 1 decreases, the volume of the spring bottle decreases under external pressure, thus ensuring that the remaining water in the water tank 1 can still fill the water tank 1 and be promptly drawn into the electrolysis module 4 by the suction module, preventing the electrolysis module 4 from drying out.

[0061] Regarding the electrolysis module 4, in one embodiment of this application, the electrolysis space of the electrolysis module 4 includes a cathode chamber 43 with a cathode 44 and an anode chamber 41 with an anode 42, and the cathode chamber 43 and the anode chamber 41 are connected. In this structural form, the electrolysis module 4 can be directly installed in the water tank 1, or it can be installed on the pipeline connecting the water tank 1 and the nozzle 2.

[0062] When the electrolysis module 4 is installed in the water tank 1, considering that the electrolysis module 4 only processes the water flow around it, and the negative oxygen ions generated thereafter gradually diffuse to the other water flow, the electrolysis module 4 is preferably installed near the pipe connecting the nozzle 2 to ensure that the water flow entering the nozzle 2 through the pipe is all water flow treated by the electrolysis module 4; or, the electrolysis module 4 is preferably installed on the pipe connecting the water tank 1 and the nozzle 2 to ensure that the water flow delivered to the nozzle 2 is all water flow treated by the electrolysis module 4.

[0063] When the cathode chamber 43 and the anode chamber 41 are fully connected, the position 2.2m away from the nozzle is monitored by a WST-1680 air ion detector manufactured by Beijing Wositeng Technology Co., Ltd. The first drive module 3 adopts a bladeless fan design, and at the lowest fan speed, the amount of negative oxygen ions is only 18,000 / cm³. 3 At the second wind speed setting, the amount of negative oxygen ions increases to 51,000 / cm³. 3 Around level three, the amount of negative oxygen ions increases again to 74,000 / cm³. 3 about.

[0064] The electrolysis space of the electrolysis module 4 can also be divided into a cathode chamber 43 with a cathode 44 and an anode chamber 41 with an anode 42 by a first partition 45. In order to achieve communication between the cathode chamber 43 and the anode chamber 41, a connection port for communicating between the cathode chamber 43 and the anode chamber 41 can be provided through the first partition 45. Alternatively, a first gap 8 can be provided between the first partition 45 and the peripheral wall of the electrolysis space to communicate between the cathode chamber 43 and the anode chamber 41.

[0065] Specifically, considering the correlation between negative oxygen ions and anode products, when a connection port connecting the cathode chamber 43 and the anode chamber 41 is provided on the first separator 45, the water inlet 46 of the electrolysis module 4 can be located in the cathode chamber 43, and correspondingly, the water outlet 47 can be located in the anode chamber 41. In this case, the distance between the water outlet 47 and the nozzle 2 is closer, which can reduce the unnecessary consumption of negative oxygen ions along the transport path to a certain extent. In this case, the first separator 45 needs to be configured as an anion channel such as an anion exchange membrane. Alternatively, when the water inlet 46 is located in the anode chamber 41 and the water outlet 47 is located in the cathode chamber 43, the first separator 45 needs to be configured as a cation channel such as a cation exchange membrane.

[0066] Alternatively, considering the complexity of setting a connection port on the first partition 45, to achieve communication between the cathode chamber 43 and the anode chamber 41, such as... Figure 5-7 As shown, a first gap 8 can be provided between the first separator 45 and the peripheral wall of the electrolysis space to connect the cathode chamber 43 and the anode chamber 41.

[0067] Correspondingly, the anode chamber 41 is connected to the first gap 8 through the second gap 9, wherein the second gap 9 may be disposed between the anode 42 and the first partition 45, and / or disposed between the anode 42 and the peripheral wall of the anode chamber 41;

[0068] The cathode chamber 43 is connected to the first gap 8 through the third gap 10, wherein the third gap 10 may be disposed between the cathode 44 and the first partition 45, and / or disposed between the cathode 44 and the peripheral wall of the cathode chamber 43.

[0069] Specifically, such as Figure 5-7 As shown, in this embodiment, the inlet 46 and outlet 47 of the electrolysis module 4 are both located on one side of the anode chamber 41, and a water-blocking structure is provided on the first partition 45.

[0070] During the electrolysis process, the water in the water tank 1 flows into the anode chamber 41 through the inlet 46 and participates in electrolysis at the anode 42. The generated hydrogen ions and other cations then enter the cathode chamber 43 through the first separator 45 and continue to participate in electrolysis at the cathode 44, generating hydrogen gas and other cathode products.

[0071] The specific reaction formula is as follows:

[0072] At anode 42: 4H₂O - 4e - →O2↑+2H2O+4H + ;

[0073] Cathode 44: 2H + +2e - →H2↑;

[0074] Since no additional water inlet 46 is provided at the cathode chamber 43, and the cathode chamber 43 and the anode chamber 41 are separated by the first partition 45, the water volume in the cathode chamber 43 during the electrolysis process is limited. To prevent the cathode 44 from burning dry during the electrolysis process, a first gap 8 is provided between the first partition 45 and the peripheral wall of the electrolysis space in this invention. The cathode chamber 43 and the anode chamber 41 are connected through the first gap 8, so that the water flow in the anode chamber 41 can enter the cathode chamber 43 through the first gap 8. This part of the water flow can prevent the cathode 44 from burning dry.

[0075] Furthermore, it should be noted that in this invention, the first separator 45 can restrict most of the water flow in the anode chamber 41 from diffusing into the cathode chamber 43. However, since the hydrogen ions and other cations generated at the anode 42 need to pass through the first separator 45 to enter the cathode chamber 43 and continue to participate in electrolysis, and water is required as a medium during the migration of ions, the first separator 45 can allow ions to carry some water through during the migration process. This water can also prevent the cathode 44 from drying out during the electrolysis process.

[0076] The first separator 45 preferably also has a gas check structure, such as a cation exchange membrane, a polytetrafluoroethylene (PTFE) composite membrane, a multilayer hydrophobic coating membrane, or other structural forms.

[0077] The working principle of the polytetrafluoroethylene composite membrane is to disperse the perfluorosulfonic acid membrane in the porous polytetrafluoroethylene framework, and to use the hydrophobicity and density of polytetrafluoroethylene to block various gases, including hydrogen.

[0078] The working principle of the multilayer hydrophobic coating membrane is to coat the surface of the cation exchange layer with an ultrathin polyvinylidene fluoride layer to block liquid water and gas from passing through.

[0079] The greater the distance between the cathode 44 and the anode 42, the higher the voltage required for electrolysis. As the electrolysis voltage increases, products such as ozone, which consume negative oxygen ions, may be generated. Therefore, in this embodiment, the cathode 44, the first separator 45, and the anode 42 are preferably stacked. Correspondingly, the cathode 44 and the anode 42 also need to have several through-holes to allow hydrogen and oxygen to escape. Ions generated during electrolysis can also directly enter adjacent chambers through the through-holes and the first separator 45.

[0080] Furthermore, considering that ions require water as a medium during migration, the first separator 45 will swell during its transmembrane diffusion. In this embodiment, by symmetrically arranging the vent holes of the cathode 44 and anode 42 on both sides of the first separator 45, when the first separator 45 swells, it can symmetrically swell into the vent holes on both sides, thereby reducing the extent of unilateral swelling and extending its service life.

[0081] The distance from the nozzle was monitored using a WST-1680 air ion detector manufactured by Beijing Wositeng Technology Co., Ltd. The first drive module 3 uses a bladeless fan; at the lowest fan speed, the negative oxygen ion concentration was only 48,000 ions / cm³. 3 At the second wind speed setting, the amount of negative oxygen ions increases to 110,000 / cm³. 3 Around level three, the amount of negative oxygen ions increases again to 140,000 / cm³. 3 This allows for the output of negative oxygen ions to cover a larger space, reducing the burden on users.

[0082] In another embodiment of this application, the electrolysis space of the electrolysis module 4 is divided into a cathode chamber 43 with a cathode 44 and an anode chamber 41 with an anode 42 by a first separator 45. In this embodiment, the cathode chamber 43 and the anode chamber 41 are not connected. Therefore, both the cathode chamber 43 and the anode chamber 41 need to be provided with independent inlets 46 and outlets 47. Since the generation of negative oxygen ions is related to the anode 41, the nozzle 2 needs to be located downstream of the outlet 47 of the anode chamber to ensure that the air in contact with the water flow can carry enough negative oxygen ions.

[0083] Alternatively, a hydrogen outlet 48 can be provided at the cathode chamber 43, connecting the cathode chamber 43 to the outside of the anode chamber 41. In this configuration, the inlet 46 and outlet 47 can be located only on one side of the anode chamber 41, and the dry burning of the cathode 44 can be prevented by the water flow carried by ions during migration. The first partition 45 needs to be equipped with a gas check valve structure accordingly.

[0084] Accordingly, since a hydrogen outlet 48 is provided, the electrolysis module 4 is not suitable to be directly installed in the water tank 1. Therefore, in this embodiment, the electrolysis module 4 is preferably installed on the pipeline connecting the water tank 1 and the nozzle 2.

[0085] The first separator 45 can be configured as an ultrafiltration membrane, a hydrophilic cation exchange membrane, a negatively charged nanofiltration membrane, or a mixed matrix membrane, etc., which allows water to flow through while blocking the diffusion of hydrogen generated at the cathode 44 across the membrane.

[0086] The hydrophilic cation membrane adsorbs water molecules through hydrophilic groups such as sulfonic acid groups to form a hydration layer, providing a transport channel for cations and water. Non-polar gas molecules are blocked because they cannot form hydrogen bonds or electrostatic interactions with the hydration layer, thus achieving the function of gas anti-reverse flow.

[0087] Negatively charged nanofiltration membranes have a negatively charged surface, and their pore size can block gases while allowing cations and water to pass through. By incorporating hydrophilic groups, a dynamic hydration layer can be formed, enhancing water transport. Gases, due to their hydrophobicity, nonpolarity, and low solubility, are trapped, thus achieving a gas anti-reverse function.

[0088] The hybrid matrix membrane uses organic polymers as the matrix and inorganic nanomaterials such as zeolite and metal-organic frameworks (MOFs) are uniformly dispersed inside. The surface charge and hydrophilicity of the materials can promote the transport of cations and water, and the gas anti-reverse function can be achieved by controlling the pore size distribution.

[0089] Furthermore, the first separator 45 can also be configured as a cation exchange membrane, a hydrophobic MOF (metal-organic framework) membrane, a hydrophobic COF (covalent organic framework) membrane, or a hydrophobic mixed matrix membrane, etc. This structure can allow hydrogen ions to carry some water into the cathode chamber 43, preventing the cathode 44 from burning dry, and can also achieve a water-blocking function. Among them, the cation exchange membrane is preferably a proton exchange membrane.

[0090] Hydrophobic MOF and COF membranes form low surface energy interfaces by introducing hydrophobic functional groups such as fluorinated groups, which block the permeation of polar water molecules and gases; their pore surfaces are modified with negatively charged groups to promote cation migration.

[0091] The hydrophobic hybrid matrix membrane uses hydrophobic polymers such as polyvinylidene fluoride as the matrix and embeds hydrophilic inorganic nanoparticles such as zeolite and sulfonated carbon nanotubes. It forms a continuous ion transport channel through hydrophilic fillers, allowing cations and their hydrated ions to pass through, while preventing gas diffusion across the membrane through the hydrophobic matrix.

[0092] In this embodiment, the cathode 44, the first separator 45, and the anode 42 are preferably stacked to reduce the electrolysis voltage required for ion migration. Correspondingly, the cathode 44 and the anode 42 are each provided with several vent holes to allow hydrogen and oxygen to escape. Ions generated during electrolysis can directly enter adjacent chambers through the vent holes and the first separator 45.

[0093] In addition, in this embodiment, the vent holes of the cathode 44 and the anode 42 are symmetrically arranged on both sides of the first separator 45, so that when the first separator 45 swells, it can symmetrically expand into the vent holes on both sides, thereby reducing the extent of its unilateral expansion and extending its service life.

[0094] The distance from the nozzle was monitored using a WST-1680 air ion detector manufactured by Beijing Wositeng Technology Co., Ltd. The first drive module 3 uses a bladeless fan; at the lowest fan speed, the negative oxygen ion concentration was only 16,000 ions / cm³. 3 At the second wind speed setting, the amount of negative oxygen ions increases to 47,000 / cm³. 3 Around level three, the amount of negative oxygen ions increases again to 69,000 per cubic centimeter. 3 about.

[0095] With several electrolysis modules 4 connected in parallel within the current equipment volume, as many negative oxygen ions as possible can be generated. Furthermore, due to the synergistic effect of the nozzle 2 and the first drive module 3, these negative oxygen ions can be fully diffused into the external environment to adjust the external air quality.

[0096] On the other hand, to prevent impurities deposited during electrolysis from adhering to the electrode surface and affecting the contact between the electrode and the conductive component, at least one electrode in the chamber of this application is provided with a conductive portion extending outward through the chamber's peripheral wall. This means the conductive portion is located outside the chamber to ensure a smooth electrical connection between the conductive component and the electrode.

[0097] Specifically, the anode 42 can penetrate the peripheral wall of the anode chamber 41 and extend outward to provide a conductive part, and / or the cathode 44 can penetrate the peripheral wall of the cathode chamber 43 and extend outward to provide a conductive part.

[0098] The portable negative oxygen ion generator of this application is also equipped with a humidity-sensitive element to control the start and stop of the electrolysis module 4.

[0099] Specifically, when water passes through the electrolysis module 4, as the humidity increases, the humidity-sensitive element can automatically control the control circuit of the electrolysis module 4 to conduct electrolysis on the water flowing through it; when water does not pass through the electrolysis module 4, as the humidity decreases, the humidity-sensitive element can automatically control the control circuit of the electrolysis module 4 to turn off to prevent the electrodes inside from drying out.

[0100] Furthermore, since negative oxygen ions are prepared through the electrolysis module 4, the product output through the nozzle 2 of this application also carries a high oxidation-reduction potential, and water with this property can also achieve a sterilization effect.

[0101] The inventors unexpectedly discovered that, in addition to sterilization, the product output through nozzle 2 also has the function of emulsifying oils. The inventors speculate that the reason the electrolytic product has this function is because the product output in this application has a high redox potential and strong oxidizing properties. Since the main component of edible oil is triglycerides, the product preferentially oxidizes unsaturated fatty acids such as oleic acid and linoleic acid, causing ester bonds to break and generating hydrophilic products such as glycerol, fatty acid fragments, and peroxides, which can be carried away with the water flow. Therefore, in addition to being used for disinfection and deodorization in the home environment, the portable negative ion generator of this application can also be used in the kitchen environment to clean oil stains.

[0102] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
