Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an air purification system, method and vehicle. Background Art

[0002] When the doors are fully closed, the vehicle forms a sealed environment, isolating external noise and pollutants. However, this may reduce the efficiency of air circulation inside the vehicle and cause odor to remain.

[0003] One prior art method provides an in-vehicle fragrance implementation method that selects fragrance materials based on the user's emotional state and distributes the fragrance through designated air vents. Another prior art method provides an in-vehicle fragrance control method that obtains information about the driver's passenger type and location, and controls the air vents based on a preset mapping between passenger type and fragrance output mode.

[0004] The above methods can remove odors in vehicles by distributing fragrance, but the diffusion speed of the fragrance in the above methods is relatively slow. Therefore, how to increase the diffusion speed of the fragrance has become an urgent problem to be solved. Summary of the Invention

[0005] The present application provides an air purification system, method and vehicle to at least solve the technical problem of slow fragrance diffusion in the related art.

[0008] In one possible embodiment, the air purification system further includes: a purification control device and a frequency adjustment device. The purification control device is used to obtain a fragrance usage demand, which indicates the fragrance type of the fragrance. The frequency adjustment device is used to adjust the frequency of the initial pulse signal based on the fragrance usage demand to obtain a pulse signal of a first frequency. The pulse signal of the first frequency is used to instruct the generation of a pulse current of the first frequency, and the pulse current of the first frequency is used to trigger the atomization of the fragrance. The frequency of the first pulse current is the first frequency.

[0009] In one possible embodiment, the fragrance types include single-fragrance and multi-fragrance types. The single-fragrance type indicates that the fragrance emits a single scent within a preset time period, while the multi-fragrance type indicates that the fragrance emits multiple scents within a preset time period. The frequency adjustment device is further configured to, when the fragrance usage requirement indicates that the fragrance type is a multi-fragrance type, perform multiple frequency adjustments on the initial pulse signal within the preset time period to obtain multiple pulse signals having different first frequencies, where the first frequency is any one of a plurality of preset frequencies, and each preset frequency corresponds to a single scent.

[0010] In one possible embodiment, the air purification system further includes an air inlet, a gas separation device, and an air outlet. The air inlet is used to collect air from the vehicle interior. The pulse current control device is further used to generate a second pulse current based on the initial pulse signal. The gas separation device is used to decompose pollutants in the vehicle interior air using the pulse current of the second frequency and a decomposition reaction catalytic substance. The air outlet is used to output the decomposed air.

[0011] In one possible embodiment, the frequency adjustment device is also used to adjust the frequency of the initial pulse signal to obtain a pulse signal of a second frequency, wherein the pulse signal of the second frequency is used to indicate the generation of a pulse current of a second frequency, and the pulse current of the second frequency is used to trigger the decomposition of pollutant molecules in the air inside the vehicle.

[0012] In one possible embodiment, the air purification system further includes a second discharge device and a filter device. The second discharge device is configured to charge pollutants in the air inside the vehicle through corona discharge, thereby generating aggregated pollutant particles. The filter device is configured to block the aggregated pollutant particles. The air outlet is further configured to output the air after the pollutants have been filtered out.

[0013] According to a second aspect of the present application, an air purification method is provided, which is applied to the air purification system of the first aspect. The air purification method includes: issuing an initial pulse signal, the initial pulse signal being used to generate a pulse current; generating a first pulse current based on the initial pulse signal, the first pulse current being used to atomize fragrance; atomizing the fragrance based on the first pulse current to obtain atomized fragrance, wherein the diameter of the atomized fragrance droplets is less than a preset diameter threshold.

[0014] In one possible embodiment, the air purification method further includes: charging the atomized fragrance by corona discharge to obtain fragrance droplets carrying an electric charge.

[0015] In one possible embodiment, the air purification method further includes: after obtaining the initial pulse signal, obtaining a fragrance usage demand, the fragrance usage demand being used to indicate a fragrance type. Based on the fragrance usage demand, the initial pulse signal is frequency-adjusted to obtain a pulse signal of a first frequency, the pulse signal of the first frequency being used to instruct generation of a pulse current of a first frequency, the pulse current of the first frequency being used to trigger atomization of the fragrance. The frequency of the first pulse current is the first frequency.

[0016] In one possible embodiment, the fragrance type includes a single fragrance type and a multi-fragrance type. The single fragrance type is used to indicate that the fragrance emits a single scent within a preset time period, and the multi-fragrance type is used to indicate that the fragrance emits multiple scents within a preset time period. Based on the fragrance usage demand, the initial pulse signal is frequency-adjusted to obtain a pulse signal of a first frequency, including: when the fragrance usage demand indicates that the fragrance type is a multi-fragrance type, the initial pulse signal is frequency-adjusted multiple times within the preset time period to obtain multiple pulse signals of different first frequencies, where the first frequency is any one of a plurality of preset frequencies, and each preset frequency corresponds to a single scent.

[0017] According to a third aspect provided by the present application, a vehicle is provided, the vehicle including the air purification system according to the first aspect.

[0018] Beneficial effects of the present invention:

[0019] (1) The fragrance is atomized by a first pulse current, atomizing the liquid into droplets smaller than a preset diameter threshold (i.e., micron-sized droplets), thereby allowing the fragrance to diffuse rapidly. Furthermore, the diffusion amount of the fragrance can be precisely controlled.

[0020] (2) The first discharge device charges the atomized fragrance through corona discharge, so that the charged fragrance droplets and the negatively charged seat fabric fibers attract each other through Coulomb force, forming a molecular-level bond, thereby allowing the fragrance droplets to remain in the vehicle for a longer time, thereby achieving long-term fragrance retention in the vehicle.

[0021] (3) By adjusting the frequency of the initial pulse signal according to the demand for fragrance use, a pulse current of the first frequency can be generated, thereby atomizing the fragrance more accurately and improving the diffusion efficiency of the fragrance.

[0022] (4) By adjusting the frequency of the initial pulse signal multiple times within a preset time period, a plurality of pulse signals of different first frequencies are obtained, and the smell of the fragrance can be dynamically adjusted, so that the air purification system can accurately control the release amount of each fragrance within the preset time period, ensuring that the multiple scents are mixed in a predetermined proportion, so that each of the multiple scents can be retained for a specific time, thereby forming a distinct olfactory experience.

[0023] (5) The second frequency pulse current and the decomposition reaction catalytic substance can decompose the pollutant molecules in the air to obtain decomposed air. In this way, the air can be purified through physical separation and catalytic reaction, without adding chemical disinfectants or adsorbents, and harmful substances can be decomposed into harmless substances, thereby more effectively purifying the air. In addition, the cost of consumables and waste disposal can be reduced.

[0024] (6) By adjusting the frequency of the pulse signal, the frequency of the pulse current can be adjusted to decompose the pollutants in the air inside the car, thereby purifying the air inside the car.

[0025] (7) By charging the pollutants in the air inside the vehicle through corona discharge, the charged pollutants can be aggregated to form aggregated pollutant particles. The aggregated pollutants are blocked by a filter device, and the air after the pollutants are filtered out can be obtained, thereby purifying the air.

[0026] (8) By emitting an initial pulse signal and generating a first pulse current based on the initial pulse signal, the fragrance can be atomized by the first pulse current to obtain an atomized fragrance. In this way, the liquid can be atomized into droplets smaller than a preset diameter threshold (i.e., micron-sized droplets), thereby allowing the fragrance to diffuse rapidly. Furthermore, the diffusion amount of the fragrance can be precisely controlled.

[0027] (9) The atomized fragrance is charged by corona discharge, so that the charged fragrance droplets and the negatively charged seat fabric fibers can be attracted to each other through Coulomb force, forming a molecular-level bond, thereby allowing the fragrance droplets to remain in the car for a longer time, thereby achieving long-term fragrance retention in the vehicle.

[0028] (10) By adjusting the frequency of the initial pulse signal according to the demand for fragrance use, a pulse current of the first frequency can be generated, thereby atomizing the fragrance more accurately and improving the diffusion efficiency of the fragrance.

[0029] (11) By adjusting the frequency of the initial pulse signal multiple times within a preset time period, a plurality of pulse signals of different first frequencies are obtained, and the smell of the fragrance can be dynamically adjusted, thereby accurately controlling the release amount of each fragrance within the preset time period, ensuring that the multiple scents are mixed in a predetermined proportion, so that each of the multiple scents can be retained for a specific time, thereby forming a distinct olfactory experience.

[0039] In order to enable ordinary people in the art to better understand the technical solutions of 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.

[0040] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0041] In some embodiments, as Figure 1 As shown, the air purification system includes: a pulse signal transmitting device 10, a pulse current control device 20 and a fragrance adjustment device 30.

[0042] The pulse signal transmitting device 10 is used to transmit an initial pulse signal, and the initial pulse signal is used to generate a pulse current.

[0043] It should be noted that the present application does not limit the pulse signal transmitting device 10. For example, the pulse signal transmitting device 10 can be a microcontroller, a function generator, a pulse generator, a pulse width modulation (PWM) chip, or a digital signal processor.

[0044] It should be noted that the pulse signal transmitting device 10 and the pulse current control device 20 can be integrated into one device.

[0045] It should be noted that the present application does not limit the pulse signal type of the initial pulse signal. For example, the waveform type of the initial pulse signal can be a rectangular pulse signal, a triangular wave pulse signal, a sine wave pulse signal, a Gaussian pulse signal, or a bell-shaped pulse signal. The amplitude type of the initial pulse signal can be a unipolar pulse signal or a bipolar pulse signal. The frequency type of the initial pulse signal can be a low-frequency pulse signal, a medium-frequency pulse signal, or a high-frequency pulse signal.

[0046] It should be understood that a low-frequency pulse signal is a pulse signal greater than a first frequency threshold and less than a second frequency threshold; a medium-frequency pulse signal is a pulse signal greater than the second frequency threshold and less than a third frequency threshold; and a high-frequency pulse signal is a pulse signal greater than the third frequency threshold. The first frequency threshold is less than the second frequency threshold, and the second frequency threshold is less than the third frequency threshold.

[0047] It should be noted that the present application does not limit the first frequency threshold, the second frequency threshold, the third frequency threshold, and the fourth frequency threshold. For example, the first frequency threshold may be 1 Hz, 2 Hz, 3 Hz, 4 Hz, or 5 Hz, the second frequency threshold may be 1 kHz, 2 kHz, 3 kHz, 4 kHz, or 5 kHz, and the third frequency threshold may be 1 MHz, 10 MHz, 20 MHz, 30 MHz, or 40 MHz.

[0048] The pulse current control device 20 is used to generate a first pulse current based on the initial pulse signal, and the first pulse current is used to atomize the fragrance.

[0049] The fragrance adjusting device 30 is used to store the fragrance and atomize the fragrance based on the first pulse current to obtain the atomized fragrance, wherein the droplet diameter of the atomized fragrance is smaller than a preset diameter threshold.

[0050] It should be noted that the present application does not impose any limitation on the preset diameter threshold. For example, the preset diameter threshold may be 1 micrometer (μm), 2 μm, 3 μm, 4 μm, 5 μm, or 20 μm.

[0051] It is understood that the fragrance adjustment device 30 atomizes the fragrance through the first pulse current, atomizing the liquid into droplets smaller than a preset diameter threshold (i.e., micron-sized droplets), which can quickly diffuse the fragrance and achieve rapid fragrance retention. Furthermore, the diffusion amount of the fragrance can be precisely controlled.

[0052] In some embodiments, as Figure 2 As shown, the air purification system further includes a first discharge device 40. The first discharge device 40 is used to charge the atomized fragrance through corona discharge to obtain fragrance droplets carrying electric charge.

[0053] It should be noted that corona discharge produces O3 - 、NO3 - Negative ions can charge the atomized fragrance.

[0054] Exemplarily, the amount of charge carried by the fragrance mist droplets satisfies Formula 1.

[0055]

[0056] Among them, q is the charge carried by the fragrance droplets, ε0 is the dielectric constant of vacuum, d is the diameter of the fragrance droplets, and E is the intensity of the pulsed electric field.

[0057] It can be understood that the first discharge device 40 charges the atomized fragrance through corona discharge, so that the charged fragrance droplets and the negatively charged materials such as seat fabric fibers are attracted to each other through Coulomb force to form molecular-level bonds, thereby allowing the fragrance droplets to remain in the vehicle for a longer time, thereby achieving long-term fragrance retention in the vehicle.

[0058] It should be noted that a pulse signal is a periodically changing electrical signal including a high level state and a low level state. The high level state is used to indicate a voltage higher than a preset voltage threshold, and the low level state is used to indicate a voltage lower than a preset voltage threshold.

[0059] In some embodiments, as Figure 2 As shown, the air purification system further includes: a first power supply 120 ; the pulse current control device 20 includes: a power switch device 201 ; and the fragrance adjustment device 30 includes: an atomization device 301 and a fragrance carrier 302 .

[0060] The first power supply 120 is used to supply power to the air purification system.

[0061] The power switch device 201 is configured to be turned on and off based on the high level state of the pulse signal and the low level state of the pulse signal, so as to convert the current flowing through the power switch device 201 into a pulse current.

[0062] The fragrance carrier 302 is used to store fragrance.

[0063] The atomization device 301 is used to atomize the fragrance based on the first pulse current to obtain the atomized fragrance.

[0064] In one possible design, the atomization device 301 atomizes the fragrance based on the pulse electric field and the first pulse current within a preset time, thereby atomizing the fragrance.

[0065] It should be noted that the present application does not limit the preset time. For example, the preset time can be 1 second, 2 seconds, 3 seconds, 4 seconds or 5 seconds.

[0066] It should be noted that the power switch device 201 rapidly switches on and off under the action of the pulse signal, converting the electrical energy provided by the first power source 120 into a pulsed current. This pulsed current is then transmitted to the atomization device 301, where it forms a pulsed electric field. The atomization device 301 then atomizes the fragrance based on the pulsed electric field and the first pulsed current, thereby atomizing the fragrance in the fragrance carrier 302 and producing an atomized fragrance.

[0067] In this way, efficient diffusion of fragrance and precise control of quantity can be achieved.

[0068] It should be noted that, during the process of atomizing fragrance using the first pulse current, it may not be possible to make all fragrance droplets smaller than the preset diameter threshold. Therefore, it is necessary to filter fragrance droplets larger than or equal to the preset diameter threshold.

[0069] In some embodiments, as Figure 2 As shown, the fragrance adjustment device 30 further includes a nanofiber filter 303 .

[0070] The nanofiber filter 303 is used to filter fragrance droplets that are larger than or equal to a preset diameter threshold.

[0071] For example, the nanofiber filter 303 can filter particles larger than 20 μm.

[0072] In this way, the consumption of fragrance can be reduced and the precise control of fragrance can be achieved.

[0073] It should be understood that the high level state of the pulse signal and the low level state of the pulse signal can control the on and off of the pulse signal, thereby controlling the first power supply 120 to generate a pulse current with the same frequency as the pulse signal.

[0074] It should be noted that the frequency of the pulse current is related to the frequency of the pulse signal, and the frequency of a pulse signal corresponds to the frequency of a pulse current.

[0075] In some embodiments, as Figure 2 As shown, the air purification system further includes: a purification control device 50 and a frequency adjustment device 60.

[0076] The purification control device 50 is used to obtain the fragrance usage demand, and the fragrance usage demand is used to indicate the fragrance type of the fragrance.

[0077] The frequency adjustment device 60 is used to adjust the frequency of the initial pulse signal based on the demand for fragrance use to obtain a pulse signal of a first frequency. The pulse signal of the first frequency is used to indicate the generation of a pulse current of a first frequency, and the pulse current of the first frequency is used to trigger the atomized fragrance.

[0078] Optionally, the frequency of the first pulse current is a first frequency.

[0079] It should be noted that the present application does not limit the first frequency. For example, the first frequency can be 10kHz, 15kHz, 20kHz, 25kHz, or 30kHz.

[0080] It is understandable that by adjusting the frequency of the initial pulse signal according to the demand for fragrance use, a pulse current of the first frequency can be generated, thereby atomizing the fragrance more accurately and improving the diffusion efficiency of the fragrance.

[0081] In the embodiment of the present application, the fragrance type includes: a single fragrance type and a multi-fragrance type. The single fragrance type is used to indicate that the fragrance emits one scent within a preset time period, and the multi-fragrance type is used to indicate that the fragrance emits multiple scents within a preset time period.

[0082] The multi-fragrance type fragrance is obtained by mixing multiple single-fragrance type fragrances.

[0083] It should be noted that there is a corresponding relationship between the pulse frequency and the fragrance of a single fragrance type. By obtaining the fragrance type and molecular characteristics, and then grouping the fragrances according to their molecular characteristics and calibrating them to different pulse frequencies, we can obtain the target pulse frequency corresponding to each fragrance type. The target fragrance pulse frequency is the pulse frequency that, among multiple pulse frequencies, results in the most stable diffusion and longest lasting fragrance for each fragrance type.

[0084] In this way, a database matching fragrance components with pulse frequencies can be established, so that the frequency adjustment device 60 can adjust the frequency of the initial pulse signal.

[0085] It should be noted that, by confirming the mixed fragrance and obtaining the pulse frequency of each fragrance in the mixed fragrance from the database, multiple frequency switching sequence combinations can be set.

[0086] Exemplarily, the mixed fragrance 1 is obtained by mixing single fragrance 1, single fragrance 2 and single fragrance 3. Then the mixed fragrance 1 can be set with six groups of frequency switching combinations. Among them, the first group of frequency switching combinations includes: single fragrance 1, single fragrance 2 and single fragrance 3, the second group of frequency switching combinations includes: single fragrance 1, single fragrance 3 and single fragrance 2, the third group of frequency switching combinations includes: single fragrance 2, single fragrance 1 and single fragrance 3, the fourth group of frequency switching combinations includes: single fragrance 2, single fragrance 3 and single fragrance 1, the fifth group of frequency switching combinations includes: single fragrance 3, single fragrance 1 and single fragrance 2, and the sixth group of frequency switching combinations includes: single fragrance 3, single fragrance 2 and single fragrance 1.

[0087] It should be noted that each frequency switching combination corresponds to multiple frequency switching time combinations, and it is necessary to ensure that the frequency of each fragrance type can operate.

[0088] For example, the first frequency switching combination corresponds to three frequency switching time combinations. The first frequency switching time combination includes: single fragrance 1 switches after one second, single fragrance 2 switches after one second, and single fragrance 3 switches after one second; the second frequency switching time combination includes: single fragrance 1 switches after two seconds, single fragrance 2 switches after two seconds, and single fragrance 3 switches after two seconds; and the third frequency switching time combination includes: single fragrance 1 switches after one second, single fragrance 2 switches after two seconds, and single fragrance 3 switches after three seconds.

[0089] It should be noted that target evaluation results of multiple persons may be obtained, and the target evaluation results are scores for each frequency switching combination and multiple frequency switching time combinations corresponding to each frequency switching combination.

[0090] In this way, the target frequency switching combination of the mixed fragrance with the highest score and the target frequency switching time combination with the highest score corresponding to the target frequency switching combination can be obtained.

[0091] In some embodiments, as Figure 2 As shown, the purification control device 50 is further configured to obtain pulse frequency combinations and frequency switching time combinations corresponding to multiple fragrance types through matching through a database based on fragrance usage requirements. The purification control device 50 is further configured to obtain pulse frequencies corresponding to single fragrance types through matching through a database based on fragrance usage requirements.

[0092] The frequency adjustment device 60 is further configured to adjust the frequency of the initial pulse signal multiple times within a preset time period to obtain multiple pulse signals of different first frequencies when the fragrance usage requirement indicates that the fragrance type is a multi-fragrance type.

[0093] The first frequency is any one of a plurality of preset frequencies, and one preset frequency corresponds to one odor.

[0094] Optionally, the frequency adjustment device 60 may perform multiple frequency adjustments on the initial pulse signal based on the target pulse frequency combination and the frequency switching time combination within a preset time period.

[0095] It should be understood that traditional single-frequency control may result in a mixture of scents when multiple fragrances are released simultaneously. By adjusting the frequency of the initial pulse signal multiple times, multiple pulse signals with different first frequencies can be generated. Pulse signals of different frequencies correspond to different fragrance release intensities and speeds. By adjusting the frequency of the initial pulse signal multiple times within a preset time period, layered fragrances can be achieved.

[0096] In this way, by adjusting the frequency of the initial pulse signal multiple times within a preset time period to obtain multiple pulse signals of different first frequencies, the smell of the fragrance can be dynamically adjusted, so that the air purification system can accurately control the release amount of each fragrance within the preset time period, ensuring that multiple smells are mixed in a predetermined proportion, so that each of the multiple fragrances can be retained for a specific time, thereby forming a distinct olfactory experience.

[0097] In some embodiments, as Figure 2 As shown, the air purification system further includes: an air inlet 70 , a gas separation device 80 and an air outlet 90 .

[0098] The air inlet 70 is used to collect air inside the vehicle.

[0099] It should be noted that the present application does not limit the air inlet 70. For example, the air inlet 70 can be a fan.

[0100] The pulse current control device 20 is further configured to generate a second pulse current based on the initial pulse signal.

[0101] The gas separation device 80 is used to decompose the pollutant molecules in the air inside the vehicle based on the pulse current of the second frequency and the decomposition reaction catalytic substance.

[0102] It should be noted that the present application does not limit the decomposition reaction catalytic material. For example, the decomposition reaction catalytic material can be titanium oxide (ie, TiO2).

[0103] Optionally, the pollution molecules include harmful molecules and odor molecules.

[0104] It should be understood that harmful molecules refer to chemical substances that exist in the atmosphere in the form of gaseous or particulate matter and have a harmful impact on human health, the ecological environment or the climate system. Odor molecules refer to odor molecules that can stimulate the olfactory organs and cause unpleasant sensations.

[0105] It should be noted that this application does not limit the pollutants. For example, the pollutants can be fine particulate matter (PM2.5), bacteria, nicotine (C 10 H 14 N2), tar, pollen, pyridine or formaldehyde, benzene and other volatile organic compounds (VOCs).

[0106] For example, the gas separation device 80 can decompose organic matter (i.e., pollutant molecules) such as formaldehyde and benzene series in the air through TiO2 catalysis, and at the same time activate the indium tin oxide (ITO) microelectrode through the second frequency pulse current to generate OH free radicals to accelerate the decomposition reaction of the pollutant molecules.

[0107] The air outlet 90 is used to output the decomposed air.

[0108] It should be noted that the present application does not limit the air outlet 90. For example, the air outlet 90 can be a fan.

[0109] It should be noted that the air inside the vehicle can be circulated from the air inlet 70 to the air outlet 90 and then from the air outlet 90 to the air inlet 70, thereby purifying the air inside the vehicle when the external gas pollution level is high.

[0110] It should be understood that the pulsed current of the second frequency can separate the gas, forming a plasma containing electrons, ions, excited molecules, and free radicals. These plasmas can directly collide with pollutant molecules, breaking their chemical bonds and causing them to dissociate into small molecular fragments. The decomposition reaction catalytic substance can catalyze the chemical reaction of the pollutant molecules, causing the pollutant molecules to decompose into harmless substances. The air inside the vehicle can be circulated from the air inlet 70 to the air outlet 90, and then from the air outlet 90 to the air inlet 70, thereby purifying the air inside the vehicle even when the level of external gas pollution is high.

[0111] In this way, the second frequency pulse current and the decomposition catalytic substance can decompose pollutant molecules in the air, producing decomposed air. This allows for air purification through physical separation and catalytic reactions, without the need for adding chemical disinfectants or adsorbents. Harmful substances can be decomposed into harmless substances, resulting in more effective air purification. Furthermore, this can reduce consumables and waste disposal costs.

[0112] In some embodiments, as Figure 2 As shown, the purification control device 50 is further used to obtain air purification requirements, and the air purification requirements are used to indicate purification of the air in the vehicle.

[0113] The frequency adjustment device 60 is also used to adjust the frequency of the initial pulse signal to obtain a pulse signal of a second frequency, wherein the pulse signal of the second frequency is used to indicate the generation of a pulse current of a second frequency, and the pulse current of the second frequency is used to trigger the decomposition of pollutant molecules in the air inside the vehicle.

[0114] It can be understood that by adjusting the frequency of the pulse signal, the frequency of the pulse current can be adjusted to decompose the pollutant molecules in the air inside the car, thereby purifying the air inside the car.

[0115] In some embodiments, as Figure 2 As shown, the air purification system further includes: a second discharge device 100 and a filter device 110 .

[0116] The second discharge device 100 is used to charge the pollutant molecules in the air inside the vehicle through corona discharge to obtain aggregated pollutant particles.

[0117] The filter device 110 is used to block the accumulated pollutant particles.

[0118] The air outlet 90 is also used to output the air after the polluted particles are filtered out.

[0119] It should be noted that the present application does not limit the filter device 110. For example, the filter device 110 can be a high efficiency particulate air filter (HEPA) filter.

[0120] It should be noted that corona discharge can generate ozone and negative ions. Ozone can oxidize and decompose volatile organic compounds such as formaldehyde and benzene, while negative ions can react with odor molecules. This can remove odor molecules and harmful molecules from the air. Furthermore, negative ions can collide with fine particles, causing them to carry an electric charge. The charged fine particles will migrate and aggregate together, forming particle aggregates, which are blocked and adsorbed by the filter device 110, thereby purifying the air.

[0121] It is understood that by charging pollutants in the air inside the vehicle through corona discharge, the charged pollutants can be aggregated to form aggregated pollutant particles. The aggregated pollutants are blocked by the filter device 110, and the air can be filtered to obtain air from which the pollutants have been filtered, thereby purifying the air.

[0122] In some embodiments, as Figure 3 As shown, the air purification system further includes: a second power supply 130.

[0128] The first sensor 140 is used to monitor the temperature of the fragrance adjustment device 30 .

[0133] It should be noted that the third sensor 160 can provide over-temperature protection for the gas separation device 80 , so that the gas separation device 80 can stop working when the temperature is too high.

[0134] In some embodiments, as Figure 3 As shown, the air purification system further includes: an environmental sensing device 180.

[0135] The environmental sensing device 180 is used to monitor the concentration of the fragrance in the vehicle and the quality of the air in the vehicle.

[0136] It should be noted that the present application does not limit the environment sensing device 180. For example, the environment sensing device 180 may be an electronic nose.

[0137] In some embodiments, as Figure 3 As shown, the air purification system further includes: a vehicle refrigerator 190. The vehicle refrigerator 190 includes: a monitoring switch 1901, an ultraviolet sterilization module 1902, and a heat preservation cavity 1903.

[0138] The monitoring switch 1901 is used to monitor whether the vehicle refrigerator 190 is turned on.

[0139] The ultraviolet sterilization module 1902 is used to sterilize the vehicle refrigerator 190 .

[0140] The heat preservation cavity 1903 is used for storing items.

[0141] In some embodiments, as Figure 3As shown, the frequency adjustment device 60 is further used to adjust the frequency of the initial pulse signal to obtain a pulse signal of a third frequency or a pulse signal of a fourth frequency. The pulse signal of the third frequency is used to indicate the generation of a pulse current of the third frequency, and the pulse signal of the fourth frequency is used to indicate the generation of a pulse current of the fourth frequency.

[0142] Optionally, the pulse current of the third frequency is used to trigger the corona discharge of the second discharge device 100 , and the pulse signal of the fourth frequency is used to trigger the ultraviolet sterilization module 1902 to sterilize the insulation cavity 1903 of the vehicle refrigerator 190 .

[0143] In some embodiments, as Figure 3 As shown, the ultraviolet sterilization module 1902 includes: a pulse xenon lamp module 19020.

[0146] The first power switch device 2001 is configured to be turned on and off based on the high level state and the low level state of the first pulse signal, so as to generate a first pulse current through the first power supply 120 or the second power supply 130 .

[0147] The second power switch device 2002 is configured to be turned on and off based on the high level state of the second pulse signal and the low level state of the second pulse signal, so as to generate a third pulse current through the first power source 120 or the second power source 130 .

[0148] The third power switch device 2003 is configured to be turned on and off based on the high level state and the low level state of the third pulse signal, so as to generate a second pulse current through the first power source 120 or the second power source 130 .

[0149] The fourth power switch device 2004 is configured to be turned on and off based on the high level state and the low level state of the fourth pulse signal to generate a fourth pulse current through the first power source 120 or the second power source 130 .

[0150] It should be noted that the purification control device 50 can control the opening or closing of the environmental sensing device 180, the pulse signal transmitting device 10, the second power supply 130, the fragrance adjustment device 30, the gas separation device 80, the second discharge device 100, the air inlet 70, and the air outlet 90 based on the concentration of the fragrance in the vehicle and the quality of the air in the vehicle.

[0151] In some embodiments, the air purification system monitors the fragrance concentration through the environmental sensing module. When the fragrance concentration is less than the first preset concentration threshold, the air purification system atomizes the fragrance based on the first pulse current through the fragrance adjustment device 30 to obtain the atomized fragrance. When the fragrance concentration is greater than or equal to the first preset concentration threshold and the fragrance concentration is less than the second preset concentration threshold, the air purification system adjusts the duty cycle of the fragrance adjustment device 30 so that the fragrance adjustment device 30 can work according to a certain cycle. When the fragrance concentration is greater than or equal to the second preset concentration threshold, the air purification system controls the fragrance adjustment device 30 to stop working. Afterwards, the air purification system opens the air inlet 70 to reduce the concentration of the fragrance. Afterwards, the air purification system is turned off.

[0152] The duty cycle refers to the ratio of the working time of the fragrance adjustment device 30 to the total time in one cycle. The second preset concentration threshold is greater than the first preset concentration threshold.

[0153] In some embodiments, the air purification system monitors the fragrance concentration via an environmental sensing module. When the fragrance concentration is less than a first predetermined concentration threshold, the air purification system activates the first discharge device 40 and charges the atomized fragrance through corona discharge from the first discharge device 40, thereby producing charged fragrance droplets.

[0154] In some embodiments, the air purification system monitors the air quality inside the vehicle through an environmental sensing module. When the air quality inside the vehicle is lower than a first air quality level, the air purification system charges pollutants in the air inside the vehicle through corona discharge from the second discharge device 100, resulting in aggregated pollutant particles. The air purification system also monitors the temperature of the second discharge device 100 through a second temperature sensor. If the temperature of the second discharge device 100 is greater than a first temperature threshold, the air purification system controls the second discharge device 100 to stop operating. If the temperature of the second discharge device 100 is less than or equal to the first temperature threshold, the air purification system charges pollutants in the air inside the vehicle through corona discharge from the second discharge device 100, resulting in aggregated pollutant particles. When the air quality inside the vehicle is lower than the first air quality level and the air purification system controls the second discharge device 100 to operate, the air purification system decomposes the pollutants in the air inside the vehicle through the gas separation device 80 using a pulsed current of a second frequency and a decomposition reaction catalytic substance, thereby obtaining decomposed air. Afterwards, the temperature of the gas separation device 80 can be monitored by the third temperature sensor. If the temperature of the gas separation device 80 is greater than the second temperature threshold, the air purification system controls the second discharge device 100 to stop working; if the temperature of the gas separation device 80 is less than or equal to the second temperature threshold, the gas separation device 80 continues to work.

[0155] In some embodiments, the air purification system monitors the air quality in the vehicle through the environment sensing module. When the air quality in the vehicle is lower than the first air quality, the external circulation air outlet 90 can be opened to allow the air in the vehicle to flow with the outside air.

[0156] In some embodiments, the air purification system monitors the air quality in the vehicle through the environment sensing module. When the air quality in the vehicle is higher than a first air quality, the air purification system stops working.

[0157] In some embodiments, the air purification system, through the environmental sensing module, monitors and detects that components of smoke odor in the vehicle include particulate pollutants, volatile organic compounds (VOCs), and odor molecules. Particulate pollutants include nicotine and tar, VOCs include formaldehyde, and odor molecules include pyridine. The air purification system then generates negative ions through a second discharge device 100. These negative ions charge the nicotine and tar, causing them to migrate and aggregate, resulting in aggregated nicotine and tar particles with larger particle sizes. The air purification system then uses a HEPA filter to block the aggregated nicotine and tar. The air purification system then activates the TiO2 in the gas separation device 80 using a pulsed current at a second frequency, causing the TiO2 to generate OH radicals, which decompose formaldehyde and nicotine. The air purification system then uses the first pulsed current to atomize a fragrance containing essential oils such as limonene through the fragrance adjustment device 30, generating an atomized fragrance. The air purification system then charges the atomized fragrance through corona discharge in the first discharge device 40, producing charged fragrance droplets. These charged fragrance droplets can adsorb onto the fiber surfaces inside the vehicle and react with pyridine, removing odors from the vehicle.

[0158] For example, the chemical equation for the reaction between OH radical and nicotine is C 10 H 14 N2+·OH→CO2+H2O+N2.

[0159] It should be noted that the purification control device 50 can obtain status information of the vehicle refrigerator 190 and control the sterilization inside the vehicle refrigerator 190 based on the status information of the vehicle refrigerator 190 .

[0160] In some embodiments, when the air purification system detects that vehicle refrigerator 190 is turned on, it activates the UV sterilization function of vehicle refrigerator 190 either on a scheduled basis or through the vehicle computer. The air purification system then sterilizes vehicle refrigerator 190 by emitting ultraviolet light from the pulsed xenon lamp module 19020 in the UV sterilization module 1902. If the air purification system detects that vehicle refrigerator 190 is turned on through monitoring switch 1901, the air purification system controls UV sterilization module 1902 to stop operating.

[0161] In some embodiments, if the vehicle refrigerator 190 is not opened within the target time period, the air purification system controls the ultraviolet sterilization module 1902 to stop working.

[0162] In some embodiments, when the air purification system detects that there is gas in the vehicle refrigerator 190 that needs to be discharged, the gas stored in the vehicle refrigerator 190 can be discharged outside the vehicle through the air outlet 90 .

[0163] For ease of understanding, the air purification method provided in this application is described in detail below with reference to the accompanying drawings.

[0164] On this basis, the present application provides an air purification method, which is applied to the above-mentioned air purification system, such as Figure 4 As shown, the air purification method includes:

[0165] S401: Send an initial pulse signal.

[0166] The initial pulse signal is used to generate a pulse current.

[0167] S402 : Generate a first pulse current based on the initial pulse signal.

[0168] The first pulse current is used to atomize the fragrance.

[0169] S403 , atomizing the fragrance based on the first pulse current to obtain atomized fragrance.

[0170] The droplet diameter of the atomized fragrance is smaller than a preset diameter threshold.

[0171] Based on the above technical solution, by emitting an initial pulse signal and generating a first pulse current based on the initial pulse signal, the fragrance can be atomized by the first pulse current to produce an atomized fragrance. In this way, the liquid can be atomized into droplets smaller than a preset diameter threshold (i.e., micron-sized droplets), thereby allowing the fragrance to diffuse rapidly. Furthermore, the amount of fragrance diffusion can be precisely controlled.

[0172] In some embodiments, the atomized fragrance may be charged by corona discharge to obtain fragrance droplets carrying an electric charge.

[0173] It can be understood that by charging the atomized fragrance through corona discharge, the charged fragrance droplets and the negatively charged materials such as seat fabric fibers can be attracted to each other through Coulomb force, forming a molecular-level bond, thereby allowing the fragrance droplets to remain in the car for a longer time, thereby achieving long-term fragrance retention in the vehicle.

[0174] In some embodiments, after obtaining the initial pulse signal, a fragrance usage demand is obtained, which indicates the fragrance type of the fragrance. Based on the fragrance usage demand, the initial pulse signal is frequency-adjusted to obtain a pulse signal of a first frequency. The pulse signal of the first frequency is used to instruct the generation of a pulse current of a first frequency, and the pulse current of the first frequency is used to trigger the atomization of the fragrance. The frequency of the first pulse current is the first frequency.

[0175] It is understandable that by adjusting the frequency of the initial pulse signal according to the demand for fragrance use, a pulse current of the first frequency can be generated, thereby atomizing the fragrance more accurately and improving the diffusion efficiency of the fragrance.

[0176] In some embodiments, fragrance types include single-fragrance types and multi-fragrance types. The single-fragrance type indicates that the fragrance emits a single scent within a preset time period, while the multi-fragrance type indicates that the fragrance emits multiple scents within a preset time period. If the fragrance usage requirement indicates that the fragrance type is multi-fragrance type, the frequency of the initial pulse signal is adjusted multiple times within the preset time period to obtain multiple pulse signals having different first frequencies. The first frequency is any one of multiple preset frequencies, and each preset frequency corresponds to a single scent.

[0177] It can be understood that by adjusting the frequency of the initial pulse signal multiple times within a preset time period to obtain multiple pulse signals of different first frequencies, the smell of the fragrance can be dynamically adjusted, thereby accurately controlling the release amount of each fragrance within the preset time period, ensuring that multiple smells are mixed in a predetermined proportion, so that each of the multiple fragrances can be retained for a specific time, thereby forming a distinct olfactory experience.

[0178] In some embodiments, air inside a vehicle may be obtained, and then a second pulse current may be generated based on the initial pulse signal. Pollutant molecules in the air inside the vehicle may be decomposed based on the pulse current of the second frequency and a decomposition reaction catalytic substance to obtain decomposed air.

[0179] It can be understood that the second frequency pulse current and the decomposition reaction catalytic substance can decompose pollutant molecules in the air, producing decomposed air. In this way, the air can be purified through physical separation and catalytic reaction, without the need to add chemical disinfectants or adsorbents, and harmful substances can be decomposed into harmless substances, thereby more effectively purifying the air. In addition, the cost of consumables and waste disposal can be reduced.

[0180] In some embodiments, the initial pulse signal can be frequency-adjusted to obtain a pulse signal of a second frequency, wherein the pulse signal of the second frequency is used to indicate the generation of a pulse current of a second frequency, and the pulse current of the second frequency is used to trigger the decomposition of pollutant molecules in the air inside the vehicle.

[0181] It can be understood that by adjusting the frequency of the pulse signal, the frequency of the pulse current can be adjusted to decompose the pollutant molecules in the air inside the car, thereby purifying the air inside the car.

[0182] In some embodiments, pollutant molecules in the air inside the vehicle can be charged by corona discharge to obtain aggregated pollutant particles, which can then be blocked to obtain air filtered of the pollutants.

[0183] It is understood that by charging pollutants in the air inside the vehicle through corona discharge, the charged pollutants can be aggregated to form aggregated pollutant particles. The aggregated pollutants are then blocked by a filter device, resulting in filtered air, thereby purifying the air.
