[0033] The realization, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed Embodiments

[0034] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] To better understand the above technical solutions, the exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0036] Currently, the oxygen generation technologies used in homes and appliances are mainly molecular sieve adsorption method and membrane separation method. The molecular sieve adsorption method is to let air pass through the molecular sieve adsorption tower, and use the molecular sieve to selectively adsorb oxygen and nitrogen components in the air to separate the air and obtain oxygen. The membrane separation method is to use the selective permeability of the polymeric membrane to separate oxygen and nitrogen from the gas mixture to obtain oxygen-rich gas.

[0037] Currently, the removal of carbon dioxide in space mainly includes soda lime method, peroxide method, LiOH method, molecular sieve adsorption method, ethanolamine liquid phase absorption method, solid amine method and membrane separation method (osmotic pressure membrane).

[0038] It can be seen that the current oxygen generation technologies in homes and appliances can only generate oxygen, cannot dehumidify or humidify, and cannot perform other treatments simultaneously, such as dehumidification or carbon dioxide adsorption. Similarly, the carbon dioxide removal technology can only remove carbon dioxide and cannot generate oxygen. Thus, it is necessary to set up multiple devices indoors currently, such as setting up an oxygen generation device to supply oxygen to the room, setting up a carbon dioxide adsorption device to remove carbon dioxide in the room, setting up a humidification device to humidify the room, etc. Setting up an oxygen generation device, a carbon dioxide adsorption device and a humidification device indoors simultaneously has limitations such as large occupied space and high equipment cost. Based on this, the following embodiments of the air treatment component are proposed in the embodiments of the present invention.

[0039] Please refer to Figure 1 , the air treatment component includes a carbon electrocatalytic combustion layer 200, a redox reaction layer 100 and an ion exchange layer 300. The ion exchange layer 300 is disposed between the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 and is used to transport the ions generated during the electrochemical reaction between the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100.

[0040] Optionally, the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 are connected to different electrodes of a power source, such that different electrochemical reactions occur in the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100.

[0041] For example, when the redox reaction layer 100 is connected to the anode of the power source, the redox reaction layer 100 is more likely to react with water. Therefore, the redox reaction layer 100 adsorbs water in the air and undergoes an oxygen evolution reaction under the action of positive electrons, releasing oxygen. The carbon electrocatalytic combustion layer 200 is connected to the cathode of the power source. The carbon electrocatalytic combustion layer 200 adsorbs carbon dioxide in the air and reduces carbon dioxide under the action of negative electrons to generate carbon oxides, such as carbon chemical substances like aldehydes and acids, which are retained in the carbon electrocatalytic combustion layer 200.

[0042] If the electrodes to which the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 are connected are switched, for example, if the redox reaction layer 100 is switched to be connected to the cathode of the power source, the redox reaction layer 100 is more likely to react with oxygen. Therefore, the redox reaction layer 100 adsorbs oxygen in the air and undergoes a chemical reaction to produce water. When the carbon electrocatalytic combustion layer 200 is connected to the anode of the power source, the positive electrons provided by the power source anode cause the carbon electrocatalytic combustion layer 200 to undergo a combustion reaction. At this time, the carbon oxides retained in the carbon electrocatalytic combustion layer 200 react to produce carbon dioxide, which is then released into the air.

[0043] Optionally, when the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 of the air treatment assembly are connected to different electrodes of a power source, different electrochemical reactions can occur, and during the reaction process, water and carbon dioxide in the air can be absorbed, and oxygen can also be generated while absorbing water and adsorbing carbon dioxide. Thus, when the air treatment assembly is applied to an air treatment device, a single air treatment device can simultaneously achieve dehumidification, carbon dioxide removal, and oxygen production, eliminating the need for multiple air treatment devices and reducing the occupied space of the devices. Moreover, after the energized electrode of the carbon electrocatalytic combustion layer 200 is switched to the cathode, through a combustion reaction, the carbon oxides in the carbon electrocatalytic combustion layer 200 can react to generate carbon dioxide, enabling the carbon electrocatalytic combustion layer 200 to continue to adsorb carbon dioxide based on the action of the negative electrode, realizing the regeneration of the carbon catalytic combustion layer.

[0044] Optionally, please refer to Figure 2 , Figure 2 which shows the working principle and process of the air treatment assembly 10: For example, when the redox reaction layer 100 is controlled to be connected to the anode of the power source and the carbon electrocatalytic combustion layer 200 is connected to the cathode of the power source.

[0045] The redox reaction layer 100 adsorbs moisture in the air and undergoes an oxygen evolution reaction. The moisture in the air decomposes into oxygen and hydrogen ions. That is, the reaction principle is: 2H2O → O2 + 4H + . Among them, the hydrogen ions are transported to the carbon electrocatalytic combustion layer 200 based on the ion exchange layer 300, and the oxygen is released into the air, realizing dehumidification and oxygen enrichment.

[0046] The carbon electrocatalytic combustion layer 200 adsorbs carbon dioxide in the air. Under the action of electrons, the carbon electrocatalytic combustion layer 200 reduces carbon dioxide to formaldehyde or formic acid and retains it on the carbon electrocatalytic combustion layer 200. Among them, the reaction principle is: CO2 + 4H + → CH3OH / CHOOH.

[0047] Optionally, please refer to Figure 3 , for example, control the cathode of the power supply connected to the redox reaction layer 100, and the anode of the power supply connected to the carbon electrocatalytic combustion layer 200.

[0048] Under the action of the anode, the carbon electrocatalytic combustion layer 200 undergoes a combustion reaction of carbon oxides in the carbon electrocatalytic combustion layer 200, and the formaldehyde or formic acid in the carbon electrocatalytic combustion layer 200 decomposes into carbon dioxide and hydrogen ions. Among them, the reaction principle is: CH3OH / CHOOH → CO2 + 4H + .

[0049] The redox reaction layer 100 adsorbs oxygen in the air. Under the action of negative electrons, the adsorbed oxygen combines with the hydrogen ions generated by the carbon electrocatalytic combustion layer 200 to undergo a reduction reaction to generate water. That is, the reaction principle is: O2 + 4H + → 2H2O.

[0050] Based on this, the air treatment component in this embodiment can control the electrodes connected to the oxidation heat exchange reaction layer and the carbon electrocatalytic combustion layer 200 as needed to realize functions such as oxygen production, dehumidification, humidification, and carbon dioxide adsorption for the air. For example, when the indoor carbon dioxide concentration is high, it adsorbs carbon dioxide and produces oxygen, or when the indoor humidity is low, it humidifies, etc. The flexibility of using the air treatment component is increased to achieve different adjustment effects.

[0051] Optionally, the air treatment component can be set in the same room. In this way, when the air treatment component is started, it can dehumidify, remove carbon dioxide, and produce oxygen in the same room, rapidly improving the comfort of the room.

[0052] Optionally, if the thicknesses of the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 are too low, the catalytic efficiency will be affected. If they are too thick, the ion conduction speed will be slow and the cost will increase. Therefore, the thickness of the redox reaction layer 100 is in the range of 7 μm to 24 μm. The catalytic material of the redox reaction layer 100 includes, but is not limited to, carbon materials loaded with noble metals or metal oxides. The thickness of the carbon electrocatalytic combustion layer 200 is in the range of 18 μm to 54 μm. The catalytic material of the carbon electrocatalytic combustion layer 200 includes, but is not limited to, carbon materials loaded with noble metals or metal oxides.

[0053] Optionally, the air treatment assembly 10 realizes dehumidification and oxygen enrichment or humidification through an electrochemical reaction, without the need for a motor drive, which can effectively avoid the influence of noise.

[0054] Optionally, the ion exchange layer 300200 includes a proton exchange membrane or a hydroxide exchange membrane. The thickness of this exchange membrane affects the proton transport process. The higher the thickness, the more stable the membrane, but the mass transfer rate decreases. If the thickness is too low, the membrane is unstable and easily punctured and damaged. Therefore, the thickness of the ion exchange membrane needs to be controlled within the range of 5 μm to 140 μm.

[0055] Optionally, please continue to refer to Figure 1 and the air treatment assembly further includes an oxygen diffusion layer 400, and the oxygen diffusion layer 400 is disposed on the side of the oxygen reduction reaction layer away from the ion exchange layer 300.

[0056] The oxygen diffusion layer 400 is used to support the oxygen reduction reaction layer, collect current, conduct gas, and remove reaction carbon oxides. The oxygen diffusion layer 400 is a porous diffusion layer.

[0057] Optionally, the thickness of the oxygen diffusion layer 400 is 80 μm to 240 μm. Among them, the thickness of the oxygen diffusion layer 400 is determined according to the relationship between the thickness and the conduction efficiency, and the thickness of the oxygen diffusion layer 400 is selected according to the conductivity required by the air treatment assembly to accurately control the air treatment efficiency, such as the oxygen production amount, etc.

[0058] Optionally, the air treatment assembly further includes a carbon dioxide adsorption layer 500, and the carbon dioxide adsorption layer 500 is disposed on the side of the carbon electrocatalytic combustion layer 200 away from the ion exchange layer 300.

[0059] The carbon dioxide adsorption layer 500 is used to support the carbon electrocatalytic combustion layer 200, collect current, conduct gas, and remove reaction carbon oxides, and the carbon dioxide adsorption layer 500 has a strong adsorption capacity and can preferably adsorb carbon dioxide when connected to the negative electrode of the power supply. The carbon dioxide adsorption layer 500 is a porous diffusion layer.

[0060] Optionally, the thickness of the carbon dioxide adsorption layer 500 is 140 μm to 240 μm. When the carbon dioxide adsorption layer 500 is too thick, it is likely to affect the gas conduction efficiency, thereby affecting the reaction efficiency on the electrode and resulting in a decrease in the CO2 removal efficiency. When the carbon dioxide adsorption layer 500 is too thin, it will affect the adsorption amount of carbon oxides for CO2 removal in the adsorption layer, leading to problems such as overflow. The carbon dioxide adsorption layer 500 has a better effect of adsorbing carbon dioxide and can quickly remove carbon oxides to achieve the effect of rapid regeneration.

[0061] Optionally, the materials of the oxygen diffusion layer 400 and the carbon dioxide adsorption layer 500 include but are not limited to at least one of carbon fiber paper, carbon fiber woven cloth, non-woven fabric, and carbon black paper.

[0062] Optionally, the air treatment assembly further includes a fixing layer 600. The fixing layer 600 is disposed on the side of the oxygen diffusion layer 400 away from the oxygen reduction reaction layer and on the side of the carbon dioxide adsorption layer 500 away from the carbon electrocatalytic combustion layer 200. In this embodiment, the fixing layer 600 is disposed outside the carbon dioxide adsorption layer 500 and the oxygen diffusion layer 400 for fixation. The two fixing layers 600 play a role of clamping and fixing, making the air treatment assembly more stable. The fixing layer 600 is made of stainless steel material.

[0063] In some embodiments, the redox reaction layer 100 can be fixedly connected to the anode of the power supply, and the carbon electrocatalytic combustion layer 200 is connected to the cathode of the power supply. In this way, the air treatment assembly has the functions of dehumidification, oxygenation, and carbon dioxide removal.

[0064] Alternatively, in some other embodiments, the electrodes connected to the redox reaction layer 100 can also be switched and adjusted according to requirements. For example, switching the connection of the redox reaction layer 100 from the anode of the power supply to the cathode of the power supply, and switching the connection of the carbon electrocatalytic combustion layer 200 from the cathode of the power supply to the anode of the power supply.

[0065] Optionally, in one embodiment, the air treatment assembly further includes a power management module. The power management module is respectively connected to the redox reaction layer 100 and the carbon electrocatalytic combustion layer 200. The power management module is used to adjust the power electrodes connected to the redox reaction layer 100 and the carbon electrocatalytic combustion layer 200.

[0066] According to the current indoor demand, control the power management module to adjust the cathode or anode of the redox reaction layer 100 connected to the power supply, and correspondingly adjust the anode or cathode of the carbon electrocatalytic combustion layer 200 connected to the power supply, so that the air treatment component has functions of dehumidification, carbon dioxide removal, oxygen enrichment, humidification, and regeneration of the carbon electrocatalytic combustion layer 200.

[0067] Continue to refer to Figures 1 to 3 , based on the above-mentioned air treatment component, the present invention further provides an air treatment device, which includes a power supply and an air treatment component, wherein the air treatment component includes:

[0068] A carbon electrocatalytic combustion layer 200, a redox reaction layer 100, and an ion exchange layer 300. The ion exchange layer 300 is disposed between the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100, and is used for transmitting ions generated during the electrochemical reaction between the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100.

[0069] Optionally, the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 are connected to different electrodes of the power supply, so that different electrochemical reactions occur between the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100.

[0070] For example, when the redox reaction layer 100 is connected to the anode of the power supply, the redox reaction layer 100 is more likely to react with water. Therefore, the redox reaction layer 100 adsorbs water in the air and undergoes an oxygen evolution reaction under the action of positive electrons, releasing oxygen. The carbon electrocatalytic combustion layer 200 is connected to the cathode of the power supply, and the carbon electrocatalytic combustion layer 200 adsorbs carbon dioxide in the air and reduces carbon dioxide to chemical substances such as formaldehyde and formic acid under the action of negative electrons, which are retained in the carbon electrocatalytic combustion layer 200.

[0071] If the electrodes connected to the carbon electrocatalytic combustion layer 200 and the redox reaction layer 100 are switched, for example, the redox reaction layer 100 is switched to be connected to the cathode of the power supply, the redox reaction layer 100 is more likely to react with oxygen. Therefore, the redox reaction layer 100 adsorbs oxygen in the air and generates water through a chemical reaction. When the carbon electrocatalytic combustion layer 200 is connected to the anode of the power supply, the positive electrons provided by the power supply anode cause the carbon electrocatalytic combustion layer 200 to undergo a combustion reaction. At this time, the formaldehyde and formic acid retained in the carbon electrocatalytic combustion layer 200 react to generate carbon dioxide, which is then released into the air.

[0072] The air treatment device of this embodiment has all the above effects of the air treatment component 10.

[0073] Optionally, the air treatment device is a new type of humidity control and oxygenation machine. Alternatively, in some embodiments, the air treatment device is a mask, face shield, etc. with humidity control and oxygenation functions, a mask or face shield with oxygenation control functions, which can reduce problems such as insufficient oxygen supply and poor breathing caused by the mask seal, making the user more comfortable to wear.

[0074] Optionally, the power supply is connected to the power management module.

[0075] The power management module is used to adjust the power electrodes connected to the redox reaction layer 100 and the carbon electrocatalytic combustion layer 200 according to indoor requirements.

[0076] If the indoor carbon dioxide concentration is too high, resulting in people being inattentive and drowsy, and there is a need to remove carbon dioxide at this time, then control the cathode of the power supply connected to the carbon electrocatalytic combustion layer 200 to adsorb indoor carbon dioxide. At the same time, control the anode of the power supply connected to the redox reaction layer 100, so that the redox reaction layer 100 undergoes an oxygen evolution reaction to provide oxygen to the room. By adsorbing carbon dioxide on one side and generating oxygen on the other side, the indoor carbon dioxide concentration can be rapidly decreased, improving the air conditioning efficiency.

[0077] If the indoor carbon dioxide concentration is relatively low, or the indoor humidity is low, it is determined that there is a need for humidification in the room at this time. Control the cathode of the power supply connected to the redox reaction layer 100 to undergo a reduction reaction to generate water and humidify the indoor air. At the same time, in order to regenerate the carbon electrocatalytic combustion layer 200, control the anode of the power supply connected to the carbon electrocatalytic combustion layer 200, so that the carbon electrocatalytic combustion layer 200 burns the carbon oxides generated when previously adsorbing carbon dioxide, avoiding excessive carbon oxides such as formaldehyde or formic acid from affecting the carbon dioxide adsorption of the carbon electrocatalytic combustion layer 200, and realizing the regeneration of the carbon electrocatalytic combustion layer 200.

[0078] Optionally, referring to Figures 1 to 3 , when the air treatment assembly is applied to the air conditioner 20, it can not only reduce the occupied space of the air treatment assembly on the ground, but also increase the contact area and air flow between the air treatment assembly and the air driven by the air duct of the air conditioner 20. Optionally, the present invention also provides an air conditioner, which includes:

[0079] A body; and

[0080] The air treatment assembly as described above, and the air treatment assembly is arranged on the body.

[0081] Optionally, the air treatment assembly is arranged in the air duct of the body.

[0082] Optionally, the air conditioner includes a controller, which is connected to the power management module of the air treatment component. The controller is configured to control the power management module so that the power management template adjusts the power electrodes connected to the redox reaction layer 100 and the carbon catalytic combustion layer of the air treatment component.

[0083] Optionally, the controller controls the power management module according to the carbon dioxide concentration value in the room where the air conditioner is located, so that the adjustment effect of the air conditioner is better.

[0084] Based on the structure and principle of the above air treatment component, the present invention also proposes a control method for the air treatment component. Please refer to Figure 4 , the control method of the air treatment component includes:

[0085] Step S10, obtaining the current environmental information in the room, where the environmental information includes at least one of the carbon dioxide concentration value and the light brightness;

[0086] Step S20, adjusting the electrodes connected to the redox reaction layer and the carbon electrocatalytic combustion layer of the air treatment component according to the reduction information.

[0087] This embodiment can be applied to an air treatment device or an air conditioner. The power supply of the air treatment component is controlled by the air treatment device or the air conditioner. The following takes the application to an air conditioner as an example for illustration.

[0088] During the use of the air conditioner, the indoor environment is always closed, and a large amount of carbon dioxide will be generated. A large amount of carbon dioxide can easily cause people to be inattentive and drowsy. At this time, it is necessary to add sufficient oxygen and / or reduce the carbon dioxide concentration to improve the indoor comfort. Start the air treatment component. Through the electrochemical reaction, CO2 is consumed on one side, and at the same time, carbon oxides are stored in the carbon electrocatalytic combustion layer, while O2 is prepared through the electrochemical reaction on the other side; by consuming CO2 and generating O2, the fresh state of the indoor environment is maintained.

[0089] When the window is open for ventilation indoors, by reversing the electrochemical reaction (switching the electrodes of the carbon electrocatalytic combustion layer and the redox reaction layer), the carbon oxides stored in the carbon electrocatalytic combustion layer are consumed by means of electrochemical oxidation (similar to combustion) to realize the regeneration of the entire module. This process is similar to respiration and will consume O2.

[0090] Therefore, this embodiment can control the start of the air treatment component based on the carbon dioxide concentration value in the room, realizing the automatic start of the air treatment component.

[0091] Optionally, a carbon dioxide concentration detection device is linked to the air conditioner. The carbon dioxide concentration detection device detects the current indoor carbon dioxide concentration value in real time or at regular intervals. After the air conditioner obtains the indoor carbon dioxide concentration value, it controls the air treatment component based on the carbon dioxide concentration value.

[0092] For example, when the carbon dioxide concentration value is relatively high, the air treatment component is controlled to remove carbon dioxide in the room. When the carbon dioxide concentration value is relatively low, the air treatment component is controlled to be restored, so that the carbon electrocatalytic combustion layer is regenerated and restored. When the carbon dioxide concentration value is within a comfortable range, the power supply to the air treatment component is stopped, and the air treatment component stops reacting.

[0093] Optionally, the environmental information further includes the indoor light brightness. For example, in the night sleep state, the indoor carbon dioxide concentration is generally relatively high. Especially when the air conditioner is turned on and the room is in a closed state, the indoor oxygen will decrease and the carbon dioxide will increase. It is easy for users to feel dizzy and weak after getting up the next day due to lack of oxygen. Based on this, in this embodiment, the air treatment component is started in the night sleep state, so that the oxygen evolution reaction occurs in the redox reaction layer, and the carbon electrocatalytic combustion layer undergoes an adsorption reduction reaction to adsorb carbon dioxide. So that in the night sleep state, there is enough oxygen and a small amount of carbon dioxide in the indoor environment, improving the comfort of the night sleep environment.

[0094] Based on this, the air treatment component can be set to be automatically started based on the light brightness. For example, when the light brightness is lower than a preset brightness, the air treatment component is started. Or, the user can manually turn on the air treatment component in the night sleep state and when the house is closed, and start the air treatment component to increase oxygen and reduce carbon. Then, when the window is ventilated, the air treatment component is manually started to perform the electrochemical oxidation reaction of the carbon catalytic combustion layer, so that the carbon catalytic combustion layer is regenerated and can continue to adsorb carbon dioxide.

[0095] It can be understood that the principle of the air treatment component in this embodiment for increasing oxygen and reducing carbon and humidifying and regenerating in the room is the same as that of the air treatment component in the above-mentioned embodiments for increasing oxygen and reducing carbon and humidifying and regenerating. It will not be elaborated here.

[0096] Optionally, in one embodiment, as Figure 5 shown, step S20 includes:

[0097] Step S21, determining whether the carbon dioxide concentration value is greater than or equal to a first preset threshold;

[0098] If so, that is, when the carbon dioxide concentration value is greater than or equal to the first preset threshold, step 22 is executed to control the anode of the power supply to be connected to the redox reaction layer, and the cathode of the power supply to be connected to the carbon electrocatalytic combustion layer.

[0099] If not, control the air treatment component to be in a stopped working state.

[0100] It can be understood that in this embodiment, the environmental information includes the carbon dioxide concentration value. In this embodiment, it is preset that the first preset threshold is the upper humidity threshold corresponding to the carbon dioxide concentration in the comfortable range. If the carbon dioxide concentration value is higher than the upper humidity threshold, it indicates that the current carbon dioxide concentration is too high, seriously affecting the comfort. At this time, it is necessary to control the air treatment component to remove carbon. For example, control the redox reaction layer to be connected to the anode of the power supply, and the redox reaction layer performs oxygen evolution and oxygen release, consuming water in the air to generate oxygen. At the same time, the carbon electrocatalytic combustion layer is connected to the cathode of the power supply, and the carbon electrocatalytic combustion layer consumes carbon dioxide in the air to generate carbon oxides such as methanol and formic acid, realizing the consumption of carbon dioxide in the air while generating oxygen.

[0101] Optionally, the first preset threshold is 1000 ppm. Above this concentration, the air is turbid, and one begins to feel drowsy. Higher concentrations can lead to dullness, inability to concentrate, mild nausea, slow thinking, and an accelerated pulse, etc.

[0102] If the carbon dioxide concentration value is lower than the upper humidity threshold, it indicates that the indoor air is relatively comfortable. At this time, the air treatment component can be made to be in a stopped working state. For example, if the air treatment component is currently in a started state, stop supplying power to the air treatment component. When the air treatment component is in an unstarted state, maintain the unstarted state of the air treatment component.

[0103] Or in another embodiment, if not, execute step S23 to determine whether the carbon dioxide concentration value is less than or equal to a second preset threshold;

[0104] If not, it indicates that there is no need to absorb carbon and generate oxygen indoors. In order to save energy, the air treatment component can be controlled to stop working.

[0105] If so, it indicates that the indoor carbon dioxide concentration is low. At this time, in order to enable the carbon electrocatalytic combustion layer to regenerate and adsorb more carbon dioxide, control it to perform an electrochemical oxidation reaction to consume the carbon oxides generated by the carbon electrocatalytic combustion layer when adsorbing carbon dioxide, so as to clear the capacity of the carbon electrocatalytic combustion layer and achieve regeneration.

[0106] That is, when the carbon dioxide concentration value is less than or equal to the second preset threshold, execute step S24 to control the redox reaction layer to be connected to the cathode of the power supply, and control the carbon electrocatalytic combustion layer to be connected to the anode of the power supply, where the first preset threshold is greater than the second preset threshold.

[0107] When the detected indoor CO2 concentration is between the second preset threshold and the first preset threshold, the air is fresh and breathing is smooth at this concentration, and the module may not be started. If the air treatment component was in the started state before, the air treatment component may be turned off. When the detected indoor CO2 concentration is less than the second preset threshold, this is equivalent to the outdoor environmental state at this time, and the regeneration of the air treatment component can be started. Control the cathode of the redox reaction layer connected to the power supply so that the redox reaction layer undergoes a reduction reaction to generate water. And control the anode of the carbon electrocatalytic combustion layer connected to the power supply to oxidize and consume the carbon oxides accumulated in the carbon electrocatalytic combustion layer, realizing the regeneration of the entire air treatment component.

[0108] It can be understood that the second preset threshold is the lower humidity threshold corresponding to the comfortable range of carbon dioxide concentration. That is, at this concentration, when controlling the carbon electrocatalytic combustion layer to undergo an oxidation reaction, generating carbon dioxide indoors will not affect indoor comfort. At this time, the carbon electrocatalytic combustion layer is regenerated and oxidized. Optionally, the first preset threshold is 1000 ppm, and the second preset threshold is 500 ppm.

[0109] This embodiment reasonably controls the air treatment component according to indoor needs, enabling an air treatment component to realize oxygen generation and carbon reduction, dehumidification, as well as the regeneration of the air treatment component and indoor humidification, etc., and the control process is simple.

[0110] Optionally, in some embodiments, when the carbon dioxide concentration value is greater than or equal to the first preset threshold and the indoor humidity is greater than or equal to the first preset humidity, the step S22 is only executed to avoid the air treatment component absorbing moisture in the air during the oxygen evolution reaction, resulting in a relatively dry indoor environment and affecting comfort.

[0111] Optionally, in some other embodiments, when the carbon dioxide concentration value is less than or equal to the second preset threshold and the indoor humidity is less than or equal to the second preset humidity, the step S24 is only executed to avoid the air treatment component discharging moisture into the indoor environment during the reduction reaction, resulting in a relatively high indoor humidity and affecting comfort.

[0112] Optionally, the first preset humidity is greater than or equal to the second preset humidity. This embodiment controls the air treatment component in combination with indoor humidity and indoor carbon dioxide concentration, enabling both indoor humidity and carbon dioxide concentration to reach equilibrium and achieving a better adjustment effect.

[0113] As an implementation method, the hardware environment architecture involved in the control method of the air treatment component can be as Figure 6 shown.

[0114] Specifically, the hardware architecture involved in the control method of the air handling component may include a terminal. For example, if the terminal is a mobile terminal or a central control device of an air conditioner, or the hardware architecture involved in the control method of the air handling component may be an air conditioner or an air handling device, etc.

[0115] As an implementation, the air conditioner or the air handling component includes: a processor 101, such as a CPU, a memory 102, and a communication bus 103. Among them, the communication bus 103 is used to realize the connection and communication between these components. The processor 102 is used to call an application program to execute a control operation.

[0116] The memory 102 can be a high-speed RAM memory or a stable memory (non-volatile memory), such as a disk memory.

[0117] It can be understood that in an embodiment, the control program for implementing the control process of the air handling component is stored in the memory 102 of the air handling device or the air conditioner. When the processor 101 calls the control program from the memory 102, the above-mentioned various embodiments are executed.

[0118] It can be understood that the air handling device includes an air handling component, a processor, a memory, and a control program stored in the memory. When the processor calls the control program, it controls the air handling component to execute the various embodiments of the control method of the air handling component as described above.

[0119] The air conditioner includes a processor, a memory, and a control program stored in the memory. When the processor calls the control program, it controls the air handling component to execute the various embodiments of the control method of the air handling component as described above.

[0120] It should be noted that the above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
