Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a method and device for disinfecting an interior of a vehicle, and a vehicle. Background Art

[0002] As consumers become more concerned about a healthy in-car environment, traditional in-car disinfection methods (such as single-use ultraviolet light and fixed-concentration ozone) have limitations: they cannot adapt to differentiated "occupied / unoccupied" scenarios (ozone is harmful to the human body and is risky when used with people present); the single disinfectant makes it difficult to balance the needs of "deep sterilization" and "safe purification"; and the lack of intelligent feedback control makes it easy for "over-disinfection" to damage the interior or "under-disinfection" to affect health. Therefore, there is an urgent need for an in-car disinfection solution that can dynamically adapt to scenarios, precisely control disinfectant substances, and provide an intelligent closed-loop system. Summary of the Invention

Through intelligent identification of disinfection modes (integration of user instructions and environmental data), dynamic regulation of disinfection substances (based on plasma discharge parameter adjustment), and collaborative linkage of hardware modules (cooperation of air-conditioning boxes, sensors, and actuators), full-scene coverage of "unmanned deep disinfection and manned safe purification" is achieved, balancing the disinfection effect with the safety of personnel / interior.

[0008] In a possible design, the main component of the first and second disinfecting substances is ozone; the main component of the third disinfecting substance is active free radicals; and the main component of the fourth disinfecting substance is negative ions.

[0009] In one possible design, the disinfectant is generated by ionization of plasma; by adjusting the ionization parameters of the plasma, the corresponding disinfectant is obtained.

[0010] In one possible design, the ionization parameters include ionization frequency and / or ionization voltage.

[0011] In one possible design, in the first disinfection mode, the air outlet and internal circulation air inlet of the air-conditioning box are opened; in the second disinfection mode, the air outlet and internal circulation air inlet of the air-conditioning box are closed; and the disinfection substance is generated in the air-conditioning box of the vehicle.

[0019] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0023] See also Figure 1 , Figure 1 This is a flow chart of a method for disinfecting a vehicle provided by an embodiment of the present application. Figure 1 As shown, the method includes:

[0024] S110 obtains the vehicle's disinfection mode information. This step relies on the in-vehicle purification mode control unit to construct a multi-dimensional pattern recognition logic. On the one hand, it receives user interaction commands (such as manually selecting "unmanned vehicle disinfection" or "human-machine coexistence air purification" modes through the in-vehicle display or mobile phone app). On the other hand, it links with the in-vehicle air quality detection unit (ozone sensor, flow sensor, bacteria and virus detector to collect real-time data) and, based on the vehicle's operating conditions (engine off / on status, air conditioning damper position, etc.), intelligently determines the disinfection requirement scenario. For example, if the bacteria and virus detector detects that the microbial concentration in the vehicle exceeds the standard and the infrared sensor (system scalable and linked) determines that no one is present, it automatically identifies the "unmanned strong disinfection mode." If the vehicle is in motion, a person is present, and the ozone sensor feedback indicates a safe concentration, it combines the flow sensor data to identify "human-machine coexistence freshness mode." Essentially, through the fusion of "user command + environmental data + operating status," the disinfection execution mode type and target parameters (such as whether high ozone concentration is required, focus on active free radicals, etc.) are clearly defined, achieving a precise mapping of "demand-mode-parameter."

[0025] S120 releases the corresponding disinfectant based on the disinfection mode information; the composition and / or content of the disinfectant can be adjusted. Based on the disinfection mode determined in S110, the multifunctional air purifier initiates coordinated control: the programmable nanosecond pulse power supply receives the mode instruction, dynamically adjusts the discharge parameters (frequency, voltage, pulse width, etc.), and drives the plasma generating electrode (dielectric barrier / flat plate / concentric cylindrical electrode, arranged in the air conditioner cabinet) to create an adaptive discharge environment.

[0026] If it is the "unmanned vehicle disinfection mode", the power supply outputs high power parameters (high frequency, high voltage), increases the discharge electric field strength, and prompts the plasma to preferentially generate high-concentration ozone (using the strong oxidizing property of ozone to achieve deep disinfection);

[0027] In the "Human-Machine Coexistence Air Purification Mode", the power supply switches to medium power parameters and adjusts the reduced electric field to the adaptive range, so that the plasma mainly produces active free radicals such as OH and O (which decompose harmful substances, kill microorganisms, and are minimally harmful to humans);

[0028] If it is "air freshness mode", the power supply uses low power parameters to guide the plasma to generate O2 negative ions (to settle particulate matter and remove odors).

[0029] At the same time, the in-car air quality monitoring unit provides real-time feedback (ozone concentration, flow rate, and bacterial and viral levels), forming a closed-loop control loop. When ozone concentration exceeds the safety threshold, the power supply automatically adjusts down; if microbial concentrations and flow rates are high, the power is increased to enhance disinfectant output. Through the chain of "power supply parameter control → plasma composition adaptation → sensor feedback correction," the composition and content of disinfectants can be dynamically adjusted, precisely matching mode requirements and achieving the technical goal of "on-demand disinfection + safe and controllable."

[0030] See also Figure 2 , Figure 2 This is a schematic diagram of the composition of a vehicle disinfection mode provided by an embodiment of the present application. Figure 2 As shown, the disinfecting mode 200 includes:

[0031] The unmanned mode 210 focuses on "deep disinfection when there is no one in the car", and the human-machine coexistence mode 220 focuses on "safe purification in scenes with people", and then uses the secondary sub-modes (air-conditioning box disinfection mode 211, whole vehicle disinfection mode 212, air purification mode 221, air freshness mode 222) to accurately match more specific scene differences.

[0032] In unmanned mode 210, the system relies on "in-vehicle no-man's-land judgment (infrared sensor, door status, etc.) + environmental demand identification (air conditioning mold risk, stubborn pollution in the whole vehicle, etc.)" to trigger tasks: If it is detected that the air conditioning system has not been cleaned for a long time and the risk of mold growth on the evaporator is high, the air conditioning box disinfection mode 211 is activated, and the programmable nanosecond pulse power supply outputs high power parameters (high frequency, high voltage) to prompt the plasma to generate a large amount of ozone. At the same time, the air conditioning outlet and the internal circulation air inlet are closed, limiting the ozone circulation only within the air conditioning box, and concentrating on disinfecting the evaporator, air duct and other components to avoid damaging the interior of the vehicle; if it is determined that there is stubborn odor or microbial contamination (such as smoke residue, influenza virus) in the vehicle and the "unmanned + closed and static" conditions are met, the whole vehicle disinfection mode 212 is activated, the power supply maintains high-power ozone generation, the air conditioning outlet and the internal circulation air inlet are opened, and the external circulation is closed, allowing ozone to circulate in the "air conditioning box + cab" connected space to achieve deep sterilization and deodorization of the entire vehicle's surface and air.

[0033] The human-machine coexistence mode 220 is adapted to the scenario of "someone in the car (driving, temporary parking, etc.) + safety first": when it is detected that the concentration of bacteria and viruses in the car exceeds the standard (such as after a person has a cold) or the concentration of harmful gases is high (formaldehyde in a new car), the air purification mode 221 is triggered, the power supply switches to medium power parameters, and the plasma reduced electric field strength is adjusted to make active free radicals (OH, O) the main products (accompanied by a small amount of O3). Its strong oxidizing property is used to decompose harmful substances and kill microorganisms. At the same time, closed-loop monitoring is performed through the ozone sensor to ensure the safety of the O3 concentration. If only daily air refreshment is needed, the air freshening mode 222 is started, the power supply is adjusted to low power, and the plasma is guided to produce O2 first.- Negative ions purify the air by settling particulate matter and neutralizing odor molecules. The whole process is non-irritating and ensures the safety of personnel. The entire mode system achieves full scene coverage from "unmanned deep disinfection" to "manned safe purification" through "layered identification of scene requirements → precise matching of sub-modes → dynamic control of air purifier parameters + linkage of air dampers and airflow paths." It relies on the strong oxidizing properties of ozone to solve stubborn pollution, and adapts to manned scenes through active free radicals and negative ions. It also uses air damper control and sensor closed loops to balance the disinfection effect with the interior and personnel safety, allowing a system to accurately respond to multiple needs and build a "scene-mode-technology" deep collaborative in-vehicle disinfection solution.

[0034] See also Figure 3 , Figure 3 This is a system structure diagram of a whole vehicle disinfection mode and a human-machine coexistence disinfection mode provided by the embodiment of this application. Figure 3 As shown, the vehicle disinfection mode and human-machine co-existence disinfection mode systems include:

[0035] The vehicle's air conditioning box 320 and the interior cab 340 are two core spaces, along with associated functional modules, each with a specific role. The air conditioning box 320 is the core execution unit for the disinfection function, serving as the core carrier of "plasma disinfection + airflow control." It integrates three key components:

[0036] Circulation fan 321: responsible for driving the air circulation, in the whole vehicle disinfection and human-machine coexistence mode, for the "air conditioning box The air flow in the "cab" of the vehicle provides power to ensure that the disinfecting substances (ozone, active free radicals, negative ions) are diffused to the target area with the air flow.

[0037] Plasma sterilization module 322: a multifunctional air purifier, which consists of a programmable nanosecond pulse power supply + plasma generating electrode, and generates ozone, active free radicals (OH, O), negative ions (O2 - ) and other disinfection substances are the "material generation source" for the execution of the mode.

[0038] Evaporator 323: Although it is not directly involved in disinfection, as a core component of the air-conditioning system, the air-conditioning box environment (humidity, temperature) in which it is located will affect the disinfection effect (such as the change in the decomposition rate of ozone under high humidity), and the indirect association mode is executed.

[0039] The vehicle's cab 340 is the target space for disinfection and serves as the target area for personnel activities and air purification. By opening the air-conditioning outlet 330 and the air-conditioning internal circulation inlet 310, an "air circulation link" is formed with the vehicle's air-conditioning box 320:

[0040] Air conditioning internal circulation air inlet 310: responsible for sucking air from the vehicle's cab into the air conditioning box, allowing polluted air to flow through the plasma disinfection module, achieving a "pollution → purification" cycle;

[0041] Air-conditioning outlet 330: The air (containing ozone, free radicals, and negative ions) treated by the disinfection module is sent back to the cab of the vehicle, completing the "purified air delivery" and building a closed-loop airflow path of "intake → processing → output".

[0042] See also Figure 4 , Figure 4 This is a structural diagram of an air-conditioning cabinet disinfection mode system provided by the embodiment of the present application. Figure 4 As shown, the air conditioning box disinfection mode system includes:

[0043] Figure 4 The presented air conditioning box disinfection mode system is based on the automobile air conditioning box (420) to build an independent disinfection closed loop, specifically for deep cleaning of the internal components of the air conditioning box. In the system, the automobile air conditioning box integrates a circulating fan (421), a plasma sterilization module (422) and an evaporator (423). The circulating fan provides power for the air flow in the box, pushing the air through the disinfection module and the evaporator; the plasma sterilization module uses a programmable nanosecond pulse power supply and a generating electrode to generate ozone, active free radicals and other disinfection substances for killing microorganisms and decomposing odors; the evaporator, as a core component of the air conditioner, is the key disinfection target and is located in the box circulation airflow path with the disinfection module.

[0044] When the mode is triggered, the driver selects the "air conditioning box sterilization mode" through the interactive terminal, and the system immediately closes the air conditioning internal circulation air inlet (410) and the air conditioning outlet (430), cutting off the air connection between the air conditioning box and the vehicle's cab (440). Only the air inside the box is allowed to circulate through the disinfection module and evaporator under the action of the circulating fan, forming an independent disinfection space. During operation, the programmable nanosecond pulse power supply sets a high discharge power to prompt the plasma to produce a large amount of ozone, and specifically clean the evaporator and air duct. The system relies on the ozone sensor in the box to monitor the concentration. When it is lower than the sterilization threshold, the power is increased. After reaching the standard, the power is maintained and the timing is started to ensure that the disinfection time covers the microbial killing cycle. When the timing ends, the disinfection module is turned off, and the circulating fan can run at low power or be linked to the external circulation to accelerate the decomposition of ozone, and the mode is exited after the concentration is safe.

[0045] This mode reuses the hardware of the vehicle disinfection system, achieves functional expansion by regulating airflow and parameters, complements the vehicle disinfection and human-machine coexistence mode scenarios, focuses on the core pollution of the air-conditioning system, accurately divides the areas for disinfection, avoids ozone damage to the vehicle interior, and builds a "full-scene, differentiated" vehicle disinfection system to efficiently solve the problem of cleaning the air-conditioning system.

[0046] See also Figure 5 , Figure 5 This is a structural diagram of a vehicle disinfection device provided by an embodiment of the present application. Figure 5 As shown, the disinfection device 500 includes:

[0047] Figure 5 The in-vehicle disinfection device 500 shown, as the core executive body of the multifunctional sterilization and disinfection system, constructs a "perception-decision-execution" closed loop through the modular collaboration of the disinfection substance generation unit (510), the disinfection mode control unit (520), and the detection unit (530). Among them, the disinfection substance generation unit (510) integrates a programmable nanosecond pulse power supply and a plasma generating electrode: the power supply can output high-frequency nanosecond pulses, and by adjusting the discharge parameters (frequency, voltage, etc.) to change the plasma reduced electric field strength, ozone, active free radicals (OH, O) + a small amount of O3, O2 at high, medium, and low power respectively. -Negative ions are adapted to different disinfection needs; the generating electrode is arranged in the air-conditioning box, converting electrical energy into plasma energy, realizing the conversion of "electrical energy → disinfection substance". The disinfection mode control unit (520) serves as the "dispatching center". On the one hand, it receives the mode instructions set by the user through the in-car screen and mobile phone APP, and on the other hand, it integrates the ozone concentration, air flow, bacteria and virus level and other data fed back by the detection unit to identify the current scene (unmanned / human-machine coexistence and sub-mode). Based on the pre-stored "parameter-mode" calibration table, the working parameters of the decision-making generation unit (such as high power corresponding to unmanned disinfection, medium and low power corresponding to human-machine coexistence) are determined, and the air-conditioning damper is linked to control the air flow path, so that the disinfection strategy can be accurately implemented. The detection unit (530) relies on the ozone sensor (monitoring the concentration of the box and the cab), the flow sensor (detecting the air intake at the front end of the electrode), and the bacteria and virus detector (collecting microbial data in the car) to build a multi-dimensional perception network. Real-time feedback of environmental data is not only the basis for the mode control unit's decision-making (such as high microbial concentration triggering high power), but also the "safety net" of the disinfection process - when ozone exceeds the standard, it triggers power reduction and external circulation. After the microorganisms meet the standard, energy saving and regulation can be carried out to ensure a balance between effect and safety. During operation, the device follows the closed loop of "detection unit sensing demand → control unit decision strategy → generation unit output of disinfection substance → detection unit feedback correction": after the user sets or the system recognizes the mode, the control unit drives the generation unit to adjust the parameters to produce active ingredients, which are transported to the target area through the air flow of the air-conditioning box; the detection unit continuously monitors and dynamically optimizes the disinfection parameters and damper status to achieve "unmanned deep sterilization, manned safe purification" scenario adaptation. The device solves the problem of "single function and extensive control" of traditional disinfection through modular reuse (one set of generation units adapts to multiple disinfection substances), intelligent closed loop (data-driven strategy adjustment) and whole-vehicle collaboration (interfacing with the air-conditioning system, intelligent interaction), becoming the "execution center" of intelligent disinfection in the car, supporting the complete link from demand identification to effect implementation, making disinfection both accurate and efficient, while taking into account safety and scenario differences.
