Description

Technical Field

[0001] This invention relates to the field of vehicle equipment technology, and in particular to an in-vehicle smoke purification system. Background Technology

[0002] As people's demands for healthy living and comfortable driving environments continue to rise, in-vehicle air quality is receiving increasing attention. In real-world scenarios, some drivers or passengers have a habit of smoking in their vehicles. The smoke produced by burning tobacco contains a large number of harmful substances (such as nicotine, tar, carbon monoxide, and various volatile organic compounds), which not only create persistent odors in the car but also adhere to interior materials, air conditioning systems, and seat fabrics, causing secondary pollution and seriously affecting in-vehicle air quality. Furthermore, even if the car owner does not smoke, if someone else has smoked in the car, the residual pollutants are difficult to remove quickly and effectively through conventional ventilation, posing a potential health risk to subsequent passengers, especially children, the elderly, pregnant women, and people with respiratory sensitivities.

[0003] Existing in-vehicle air purification devices mostly focus on filtering particulate matter or general odors. They lack targeted structural designs for the complex chemical composition and strong adhesion of tobacco smoke, making it difficult to quickly and thoroughly remove tobacco smoke and its residual pollutants from the vehicle.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an in-vehicle smoke purification system that specifically addresses the high-pollution scenario of smoking inside a vehicle. Through intelligent sensing by the sensing and positioning unit and deep chemical adsorption and decomposition by the purification unit, it can quickly respond and activate, efficiently remove particulate matter, thoroughly decompose odor molecules, and eliminate tobacco smoke and its residual pollutants inside the vehicle, providing users with a healthy and clean in-vehicle environment.

[0006] The specific details of the technical solution provided by this invention are as follows:

[0007] A vehicle-mounted smoke purification system, comprising:

[0008] The sensing and positioning unit is installed on the inner wall of the vehicle body and includes a sensor and a positioning analyzer. The sensor is connected to the positioning analyzer. The sensor monitors the air pollutant index in the vehicle in real time and triggers the positioning analyzer and other units of the system to start based on the air pollutant index.

[0009] The purification unit includes a multi-level purification module and a sterilization module. The sterilization module is located in front of the multi-level purification module or in front of the air outlet. It is used to kill bacteria and viruses intercepted in the multi-level purification module and to assist in the decomposition of some organic pollutants.

[0010] The air control unit includes an air duct and a motor. The air duct ensures that air flows through the purification unit, and the motor is connected to the ventilation duct and sucks away the exhaust smoke.

[0011] The intelligent control and display unit is connected to the sensing and positioning unit and the risk control unit. It receives data information from the sensing and positioning unit and adjusts the operation of the risk control unit according to the data information.

[0012] Furthermore, one or more sensors are provided, and the sensors are installed on the top wall of the vehicle at different seats inside the vehicle;

[0013] The sensor is a high-sensitivity PM2.5 sensor and / or VOC sensor.

[0014] Furthermore, the positioning analyzer is an infrared positioning analyzer or an airflow analyzer, and multiple positioning analyzers are installed inside the vehicle body.

[0015] Infrared positioning analyzers use thermal imaging technology to determine the location of smokers, while airflow analyzers determine the location of smokers by detecting marker components in tobacco smoke.

[0016] The location analyzer transmits the acquired smoker's location data to the intelligent control and display unit, which then adjusts the wind direction of the wind control unit accordingly.

[0017] Furthermore, the multi-level purification module includes a HEPA filter layer and a modified activated carbon filter layer. The HEPA filter layer is placed before the modified activated carbon filter layer, and both the HEPA filter layer and the modified activated carbon filter layer are detachably installed in the air duct through filter frames.

[0018] Furthermore, the modified activated carbon filter layer is provided with high iodine value activated carbon particles, and the modified activated carbon filter layer is an activated carbon filter layer that has undergone special impregnation treatment.

[0019] Specially impregnated activated carbon filter layers include activated carbon filter layers impregnated with KMnO4 and / or catalysts.

[0020] Furthermore, the air duct includes an air intake and an air outlet, with the air intake located at a potential smoking location and the air outlet located in an area that blows directly towards non-personnel areas;

[0021] Potential smoking locations include the rear of the center console and the roof area corresponding to the seats. Areas where the air blows directly towards non-personnel include the side windows and the rear window.

[0022] Furthermore, the motor is a brushless DC motor, which achieves intelligent airflow mode switching by controlling multiple speed levels;

[0023] Intelligent airflow modes include smoke extraction mode, silent mode, and automatic mode;

[0024] The motor is electrically or signal-connected to the intelligent control and display unit. The brushless DC motor performs multi-level speed control according to the command signals sent by the intelligent control and display unit.

[0025] Furthermore, the vehicle-mounted smoke purification system also includes a filtration unit, located at the initial end of the smoke purification system, including a filter screen and / or filter cotton, for intercepting soot and larger particulate matter;

[0026] The filter screen is made of stainless steel, and the filter cotton is pre-filter cotton.

[0027] Furthermore, the vehicle-mounted smoke purification system also includes an ion generating unit, which includes a plasma generator and / or a negative ion generator. The plasma generator and / or negative ion generator are installed inside the air duct. The ion generating unit charges tiny ions and aggregates them into large particles, which facilitates subsequent filtration or sedimentation and partially decomposes harmful gas molecules.

[0028] Furthermore, the vehicle-mounted smoke purification system also includes an ashtray, which is equipped with a snap-fit ​​sealing cover and is made of metal.

[0029] The ashtray can be placed on the side of the center console or around the air conditioning vent grille, and the ashtray is fixed to the vehicle body by magnetic connection.

[0030] Compared with the prior art, the present invention has the following beneficial technical effects:

[0031] (1) This invention specifically addresses the high-pollution scenario of smoking in vehicles. It uses a sensing and positioning unit to monitor pollutants in real time and trigger the system to start, achieving "purification on demand" and avoiding energy waste. The multi-level purification and sterilization modules work together to not only remove particulate matter and gaseous pollutants, but also inactivate pathogenic microorganisms, improving health and safety. The air control unit ensures directional airflow and improves purification efficiency. The intelligent control and display unit realizes data-driven dynamic regulation, improving the system's intelligence level and user experience.

[0032] (2) The infrared positioning analyzer identifies the heat source of the smoker's hands or mouth through thermal imaging, while the airflow analyzer achieves precise positioning by detecting specific chemical components in the smoke (such as nicotine, carbon monoxide, etc.). Multiple analyzers work together to improve the robustness of positioning. The intelligent control and display unit adjusts the airflow direction accordingly to make the air intake point aligned with the pollution source, achieving "source extraction", which significantly improves the smoke capture efficiency and reduces diffusion.

[0033] (3) The HEPA filter can effectively intercept particulate matter larger than PM0.3 (including smoke, bacteria, etc.) and protect the activated carbon layer at the back from clogging; the modified activated carbon layer is placed at the back and focuses on adsorbing gaseous pollutants such as VOCs and odors; the high iodine value activated carbon enhances the adsorption capacity of small molecule organic matter; after being impregnated with KMnO4 (potassium permanganate) or catalyst, the activated carbon has the function of catalytic oxidation, which can decompose some VOCs (such as formaldehyde and benzene series) into harmless substances (CO2, H2O). The above multi-level purification module structure and the special treatment of the modified activated carbon filter layer can improve the thoroughness of purification and avoid the secondary release of harmful substances;

[0034] (4) The vehicle-mounted smoke purification system realizes the whole-chain smoke purification of precise perception, intelligent positioning, directional suction and multi-level purification. It not only efficiently removes particulate matter, harmful gases and microorganisms in tobacco smoke, but also completely decomposes odor molecules, providing a clean and hygienic in-vehicle environment for users who need to smoke.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] As attached Figure 1 As shown, a vehicle-mounted smoke purification system includes:

[0047] The sensing and positioning unit 10 is installed on the inner wall of the vehicle body and includes a sensor 101 and a positioning analyzer 102. The sensor 101 is connected to the positioning analyzer 102. The sensor 101 monitors the air pollutant index in the vehicle in real time and triggers the positioning analyzer 102 and other units of the system to start according to the air pollutant index.

[0048] The purification unit 30 includes a multi-level purification module 301 and a sterilization module 302. The sterilization module 302 is located in front of the multi-level purification module 301 or in front of the air outlet, and is used to kill bacteria and viruses intercepted in the multi-level purification module 301 and to assist in the decomposition of some organic pollutants.

[0049] The air control unit 50 includes an air duct 501 and a motor 502. The air duct 501 ensures that air flows through the purification unit 30, and the motor 502 connects to the air duct 501 and sucks away the exhaust smoke.

[0050] The intelligent control and display unit 40 is connected to the sensing and positioning unit 10 and the risk control unit 50, receives data information from the sensing and positioning unit 10, and regulates the operation of the risk control unit 50 according to the data information.

[0051] In the above technical solution, the sensing and positioning unit 10 monitors pollutants in real time and triggers the system to start, achieving "purification on demand" and avoiding energy waste; the multi-level purification and sterilization module 302 works in synergy to not only remove particulate matter and gaseous pollutants, but also inactivate pathogenic microorganisms, improving health and safety; the air control unit 50 ensures directional airflow and improves purification efficiency; and the intelligent control and display unit 40 realizes data-driven dynamic regulation, improving the system's intelligence level and user experience.

[0052] In some embodiments, one or more sensors 101 are provided, and the sensors 101 are installed on the top wall of different seats in the vehicle; the sensors 101 are high-sensitivity PM2.5 sensors and / or VOC sensors. The high-sensitivity sensors can monitor the air quality inside the vehicle in real time, and smoking instantly triggers the start of the purification system.

[0053] Sensor 101 is deployed on the top wall of different seats in the vehicle, close to the human breathing area, to quickly capture changes in local smoke concentration; it adopts a high-sensitivity PM2.5 and / or VOC sensor, which can accurately identify fine particulate matter and volatile organic compounds (such as benzene, formaldehyde, etc.) in tobacco smoke, providing a highly reliable input signal for the system and improving response speed and positioning accuracy.

[0054] In some embodiments, sensor 101 is electrically or signal-connected to positioning analyzer 102.

[0055] The function of sensor 101 during use includes: when sensor 101 detects a PM2.5 value ≥35 ug / m³ in the air inside the vehicle. 3 Alternatively, if the VOC content value is ≥0.5 mg / m³, the positioning analyzer 102 is activated, and at the same time, the sensor 101 transmits the above data signal to the intelligent control and display unit 40. The intelligent control and display unit 40 displays the PM2.5 value or VOC content value on the intelligent screen, and at the same time controls the purification unit 30 and the air control unit 50 to start operation.

[0056] In some embodiments, the positioning analyzer 102 is an infrared positioning analyzer or an airflow analyzer, and multiple positioning analyzers 102 are installed inside the vehicle body.

[0057] Infrared positioning analyzers use thermal imaging technology to determine the location of smokers, while airflow analyzers determine the location of smokers by detecting marker components in tobacco smoke.

[0058] The location analyzer 102 transmits the acquired smoker's location data to the intelligent control and display unit 40, which then adjusts the operating direction of the wind control unit 50 accordingly.

[0059] Specifically, infrared positioning identifies the heat source of the smoker's hands or mouth through thermal imaging, while the airflow analyzer achieves precise positioning by detecting specific chemical components in the smoke (such as nicotine and carbon monoxide). During operation, multiple analyzers work together to improve positioning robustness. The intelligent control and display unit 40 adjusts the airflow direction accordingly, aligning the air intake with the pollution source to achieve source extraction, significantly improving smoke capture efficiency and reducing diffusion.

[0060] Furthermore, the intelligent control and display unit 40 adjusts the operation of the risk control unit 50 according to the smoker's location, including: the intelligent control and display unit 40 receives data transmitted by the infrared positioning analyzer or airflow analyzer to determine the smoker's location or specific direction.

[0061] The intelligent control and display unit 40 receives positioning data and determines the optimal air intake orientation based on the positioning data.

[0062] The intelligent control and display unit 40 transmits the control signal of the air intake orientation to the motor 502, which drives the damper or guide vane to rotate, so that the air intake is aligned with the source of the flue gas.

[0063] The air intake is directly facing the initial diffusion path of the smoke, forming a local negative pressure zone to quickly draw in the smoke source and reduce the spread of smoke inside the cabin.

[0064] Optionally, an angle encoder or position sensor can be installed at the air intake to provide real-time feedback on the current angle of the damper and transmit the current angle signal of the damper to the intelligent control unit. The intelligent control unit compares it with the optimal air intake orientation to achieve closed-loop control and ensure steering accuracy.

[0065] In some embodiments, the multi-level purification module 301 includes a HEPA filter layer and a modified activated carbon filter layer. The HEPA filter layer is placed in front of the modified activated carbon filter layer, and both the HEPA filter layer and the modified activated carbon filter layer are detachably installed in the air duct 501 through filter frames.

[0066] The HEPA filter at the front can efficiently intercept particulate matter larger than PM0.3 (including smoke, bacteria, etc.) and protect the activated carbon layer at the back from clogging; the modified activated carbon layer is placed at the back and focuses on adsorbing gaseous pollutants such as VOCs and odors; the detachable filter frame design makes it easy for users to replace and maintain the filter, extending the system's lifespan and reducing operating costs.

[0067] Furthermore, the modified activated carbon filter layer is provided with high iodine value activated carbon particles, and the modified activated carbon filter layer is an activated carbon filter layer that has undergone special impregnation treatment.

[0068] Specially impregnated activated carbon filter layers include activated carbon filter layers impregnated with KMnO4 and / or catalysts.

[0069] High-iodine-value activated carbon enhances the adsorption capacity for small-molecule organic matter. After being impregnated with KMnO4 (potassium permanganate) or a catalyst, the activated carbon has catalytic oxidation function, which can decompose some VOCs (such as formaldehyde and benzene series compounds) into harmless substances (CO2, H2O), rather than just physical adsorption, thus avoiding secondary release and improving the thoroughness and long-lasting effect of purification.

[0070] In some embodiments, the vehicle-mounted smoke purification system further includes a filter unit 20 disposed at the initial end of the smoke purification system, including a filter screen and / or filter cotton, for intercepting soot and larger particulate matter.

[0071] Preferably, the filter screen is a stainless steel metal filter screen, and the filter cotton is a pre-filter cotton.

[0072] Stainless steel metal mesh is used to intercept soot and larger particles, protecting subsequent filter elements. It is washable and reusable. The pre-filter cotton can be used to further intercept larger particles and extend the life of the HEPA filter.

[0073] It should be further explained that the filter unit 20 is located before the multi-level purification module 301, which can effectively intercept soot, hair, large dust particles, etc., to prevent them from entering the multi-level purification module 301 and causing blockage or pollution, thus extending the life of HEPA and activated carbon filters, reducing maintenance frequency, and improving the overall operational reliability of the system.

[0074] In some embodiments, the air duct 501 includes an air intake and an air outlet, the air intake being located at a potential smoking location and the air outlet being located in an area that blows directly toward non-personnel areas.

[0075] Potential smoking locations include the rear of the center armrest, the roof area corresponding to the seat, and areas not directly exposed to airflow, including side windows and rear windows.

[0076] For example, depending on the different locations of the air intake and exhaust vents of the air duct 501, the air duct 501 can be divided into three types: rear-mounted type, headrest-mounted type, and concealed type. Specifically, the rear-mounted type includes: the air duct 501 is installed below the rear air conditioning vents or at the rear of the center armrest, with the air intake facing forward and the air exhaust vents facing backward or to the sides. This facilitates coverage of both the front and rear rows.

[0077] Headrest-mounted type: It is hung behind the headrest of the driver or passenger seat, with the air intake close to the front nose and mouth area and the air outlet facing backward. It is highly targeted and can quickly remove smoke.

[0078] Concealed type: The air intake and filter compartment are integrated into the interior panel (such as the B-pillar and headliner), leaving only the air outlet and maintenance access.

[0079] Each filter layer is set inside the air duct 501. The air duct 501 ensures that air passes through all filter layers efficiently, reducing wind resistance and noise. In the specific design, the air intake is set at the potential smoking location to achieve nearby capture, and the air outlet avoids the area where people are directly blown, so as to avoid the purified airflow disturbing the comfort of passengers, while promoting the air circulation in the vehicle and preventing pollutants from accumulating in local dead corners.

[0080] Furthermore, a motor 502 is installed in or at the end of the air duct 501. The motor 502 is a brushless DC motor 502, which achieves intelligent airflow mode switching by controlling multiple speed levels;

[0081] Intelligent airflow modes include smoke extraction mode, silent mode, and automatic mode;

[0082] The motor 502 is electrically or signal-connected to the intelligent control and display unit 40. The brushless DC motor 502 performs multi-level speed control according to the command signals sent by the intelligent control and display unit 40.

[0083] When sensor 101 detects high PM2.5 and / or VOC levels, motor 502 operates at high speed, and the air control unit 50 is in smoking mode. During low-noise operation at night or in quiet environments, the air control unit 50 (motor 502) is in silent mode. When motor 502 adaptively adjusts its speed based on the PM2.5 and / or VOC levels detected by sensor 101, the air control unit 50 is in automatic mode. These different airflow modes balance purification efficiency and passenger comfort. Sensor 101 and motor 502 are both connected to the intelligent control and display unit 40. The intelligent control and display unit 40 receives information from sensor 101 and outputs commands to motor 502 to drive its operation.

[0084] In some embodiments, the vehicle-mounted smoke purification system further includes an ion generating unit 60, which includes a plasma generator 601 and / or a negative ion generator 602. The plasma generator 601 and / or the negative ion generator 602 are installed in the air duct 501. The ion generating unit 60 charges tiny ions and aggregates them into large particles, which facilitates subsequent filtration or sedimentation and partially decomposes harmful gas molecules.

[0085] The plasma generator 601 and / or negative ion generator 602 generate a large number of positive / negative ions through high-voltage ionization, which causes tiny particles (especially nano-sized particles that are not completely captured by HEPA) to become charged and aggregate into larger particles, making them easier to filter or settle later. The large number of positive / negative ions can partially decompose harmful molecules such as formaldehyde and benzene, and can also neutralize some odors.

[0086] For example, plasma generator 601 and / or negative ion generator 602 can be installed between filter unit 20 and purification unit 30 to process the coarsely filtered gas, so that purification unit 30 can subsequently purify and remove charged particulate matter.

[0087] In some embodiments, the vehicle-mounted smoke purification system further includes an ashtray, which is provided with a snap-fit ​​sealing cover and is made of metal material;

[0088] The ashtray can be placed on the side of the center console or around the air conditioning vent grille, and the ashtray is fixed to the vehicle body by magnetic connection.

[0089] For example, the bottom of the ashtray is equipped with a strong magnet, which can be firmly attached to a designated metal location in the car (such as the side of the center console or the air conditioning vent grille), making it convenient for smokers to flick off cigarette ash, reducing ash scattering, and improving the experience.

[0090] The operating principle of the above-mentioned vehicle-mounted smoke purification system includes:

[0091] Sensor 101 monitors the PM2.5 or VOC levels of air pollutants inside the vehicle in real time.

[0092] When sensor 101 detects a PM2.5 level ≥ 35 ug / m³ in the air inside the vehicle... 3 Or, if the VOC content value is ≥0.5 mg / m³, the positioning analyzer 102 is activated, and at the same time, the sensor 101 transmits the above data signal to the intelligent control and display unit 40. The intelligent control and display unit 40 displays the PM2.5 value or VOC content value on the intelligent screen, and at the same time controls the wind control unit 50 and the purification unit 30 to start operation.

[0093] The positioning analyzer 102 detects and obtains the smoker's location, and the intelligent control and display unit 40 adjusts the operation of the wind control unit 50 according to the smoker's location (specifically, by rotating the damper or guide vanes to change the airflow direction and thus aim at the smoker).

[0094] When the PM2.5 value is ≥70 ug / m3 or the VOC content is ≥0.6 mg / m³, the wind control unit 50 operates in smoke mode, and the motor 502 runs at high speed.

[0095] When the PM2.5 value is <70 ug / m3 and the VOC content value is <0.6 mg / m3, the wind control unit 50 operates in automatic mode, and the motor 502 operates at low to medium speed.

[0096] In parallel with this, when operating at night or in a quiet environment with low noise, the wind control unit 50 (motor 502) also runs in silent mode.

[0097] With the operation of the wind control unit 50, the smoke passes through the filtration unit 20, the ion generation unit 60, and the purification unit 30 in sequence, effectively removing particulate matter, harmful gases, and microorganisms from tobacco smoke, significantly improving the air quality inside the vehicle and protecting the health of drivers and passengers.

[0098] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
