[0042] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0043] The unique characteristics of the enclosed space inside a vehicle, the diversity of pollutants, the significant health hazards, and the continuously upgrading societal demand for "healthy travel" are key issues highlighted in the automotive industry's transformation from "functional fulfillment" to "quality assurance." The car cabin is a typical small-volume, highly enclosed, and material-intensive space. Its unique physical environment exacerbates the risks and hazards of gaseous pollution. Passenger car cabins typically have a volume of only 2-3 cubic meters, and for sound insulation, heat insulation, and energy conservation, windows are usually kept closed, resulting in low natural ventilation efficiency and easily forming a double pollution loop of "external infiltration + internal release," with pollutant types and concentrations far exceeding those of ordinary indoor environments. In related technologies, in-vehicle gas purification systems typically automatically detect the gas quality inside the vehicle after startup and activate the purification function; however, for users, the gas purification experience is not noticeable.

[0044] The following is for reference. Figures 1-8 This invention describes a gas purification module 11, a gas purification method, and a vehicle according to an embodiment of the present invention.

[0045] An embodiment of the first aspect of the present invention provides a gas purification device assembly 1 for a vehicle, comprising: a purification module 11 for purifying gas; a first detection module 12 disposed at the exhaust port of the purification module 11 for detecting the purified quality parameters of the gas discharged after purification by the purification module 11; and a display module 13 connected to the first detection module 12 for at least displaying the purified quality parameters.

[0046] Specifically, such asFigure 1 and Figure 5 As shown, the vehicle's gas purification assembly 1 includes a purification module 11 for purifying the gas inside the vehicle; a first detection module 12 located at the exhaust port of the purification module 11 for detecting the purified quality parameters of the gas discharged after purification by the purification module 11 and displaying them on a display module 13, so that users can intuitively feel the degree of purification of the discharged gas and improve the riding experience. It can be understood that the purification module 11 includes physical filtration types, such as HEPA high-efficiency filtration, activated carbon adsorption, and electrostatic adsorption; chemical decomposition types, such as photocatalytic purification, plasma purification, catalytic oxidation, and amine / aldehyde capture; biological purification types, such as negative ion purification, bio-enzyme purification, and plant extract purification; and composite types, integrating two or more purification technologies to achieve all-dimensional purification of "particulate matter + gaseous pollutants + microorganisms".

[0047] In some embodiments, a second detection module 14 is further included, which is used to detect the current quality parameters of the gas inside the vehicle; the second detection module 14 is connected to the purification module 11 and the display module 13 respectively, the purification module 11 is turned on or off based on the current quality parameters, and the display module 13 is used to display the current quality parameters.

[0048] Specifically, such as Figure 1 As shown, the gas purification device assembly 1 also includes a second detection module 14, used to detect the current quality parameters of the gas inside the vehicle. The second detection module 14 is connected to the purification module 11 and the display module 13 respectively. Based on the current quality parameters of the gas inside the vehicle, it determines whether to activate the purification module 11 and displays the current quality parameters of the gas inside the vehicle on the display module 13 for the user to intuitively understand and decide whether to actively activate the purification function. This embodiment can activate the purification module 11 when needed, which is beneficial for energy conservation and emission reduction, and improves human-machine interaction.

[0049] In some embodiments, the first detection module 12 includes a first sensor unit, which includes one or more of a PM2.5 sensor, a formaldehyde sensor, a toluene sensor, and a TVOC sensor.

[0050] Specifically, such as Figure 2As shown, the first detection module 12 includes a first sensor unit, comprising a PM2.5 sensor, a formaldehyde sensor, a toluene sensor, and a TVOC sensor. Each sensor is independent and has sensitivity characteristics to specific types of substances: (a) PM2.5 sensor: used to detect suspended particulate matter in the passenger compartment air; (b) formaldehyde sensor: used to detect the formaldehyde concentration inside the passenger compartment; (c) toluene sensor: used to detect the toluene concentration inside the passenger compartment; (d) TVOC sensor: used to detect the total volatile organic compound concentration inside the passenger compartment. It should be noted that this invention does not limit the type or number of sensors. This embodiment provides a broad range of gas quality assessment dimensions, which can largely ensure a high-quality gas environment inside the vehicle.

[0051] In some embodiments, the gas purification device assembly 1 further includes a second detection module 14, which is connected to the purification module 11 and is used to detect the quality of the gas inside the vehicle; the second detection module 14 includes a second sensor unit, which includes one or more of a PM2.5 sensor, a formaldehyde sensor, a toluene sensor, and a TVOC sensor.

[0052] Specifically, such as Figure 1 As shown, the gas purification device assembly 1 also includes a second detection module 14, which is connected to the purification module 11 and the display module 13. The second detection module 14 determines whether to activate the purification module 11 based on the current quality parameters of the gas inside the vehicle, and displays the current quality parameters of the gas inside the vehicle on the display module 13 for the user's intuitive understanding, thereby deciding whether to actively activate the purification function. Furthermore, as... Figure 3 As shown, the second detection module 14 includes a second sensor unit, which includes a PM2.5 sensor, a formaldehyde sensor, a toluene sensor, and a TVOC sensor. It should be noted that this invention does not limit the type or number of sensors. This embodiment provides a broad range of gas quality assessment dimensions, which can largely ensure a high-quality gas environment inside the vehicle.

[0053] In some embodiments, the purification module 11 includes a filter sub-module 111, a decomposition sub-module 112, and a disinfection sub-module 113; wherein, the filter sub-module 111 is used to filter particulate matter in the gas; the decomposition sub-module 112 is used to decompose organic matter in the gas; and the disinfection sub-module 113 is used to eliminate bacteria and viruses in the gas.

[0054] Specifically, such as Figure 4As shown, the purification module 11 includes a filter sub-module 111, a decomposition sub-module 112, and a disinfection sub-module 113. The filter sub-module 111 can filter particulate matter in the gas, such as PM2.5. The decomposition sub-module 112 can decompose organic matter in the gas, and the decomposition products are CO2 and water, which have high-efficiency purification and environmental protection characteristics. The disinfection sub-module 113 mainly plays an antibacterial role, which can eliminate bacteria and viruses in the gas to improve the air purification quality inside the passenger cabin.

[0055] In some embodiments, such as Figure 1 As shown, the gas purification device assembly 1 also includes a control module 15, which is used to control the purification module 11 to be turned on or off. The control module 15 can determine the current quality parameters of the gas inside the vehicle, decide whether to turn the purification module 11 on or off, and control the power supply module 16 to supply power to or cut off power to the purification module 11.

[0056] In some embodiments, such as Figure 1 As shown, the gas purification device assembly 1 also includes a power supply module 16, which supplies power to the purification module 11, the first detection module 12, the display module 13, the second detection module 14, and the control module 15. It should be noted that the power supply module 16 of the gas purification device assembly 1 can operate independently of the vehicle's low-voltage power supply. That is, the gas purification device assembly 1 in this embodiment does not rely on the vehicle being powered on; it can be turned on independently to purify the in-vehicle air before the user gets in, thus improving the driving experience.

[0057] In some embodiments, the system further includes a plug 17, which is disposed at the air inlet of the purification module 11 and opens when the purification module 11 is turned on.

[0058] Specifically, such as Figure 1 As shown, the gas purification device assembly 1 also includes a plug 17, which is located at the air inlet of the purification module 11. When the purification module 11 is turned on, the plug 17 is opened. It is understood that there may be large particulate impurities in the gas, such as leaves or lint. When the purification module 11 is turned off, the plug 17 located at the air inlet of the purification module 11 can block impurities in the gas, preventing damage to the components inside the purification module 11 or accumulation of dirt.

[0059] In some embodiments, the system further includes a fan 18, which is disposed at the air inlet and / or exhaust outlet of the purification module 11 to accelerate the gas flow rate.

[0060] Specifically, such as Figure 1 As shown, the gas purification device assembly 1 also includes a fan 18, which is located at the air inlet of the purification module 11 and can accelerate the flow rate of gas into the purification module 11.

[0061] In another embodiment, such asFigure 1 As shown, the fan 18 is located at the air outlet of the purification module 11, which can accelerate the flow rate of gas discharged from the purification module 11.

[0062] In yet another embodiment, such as Figure 1 As shown, the fan 18 is located at the air inlet and air outlet of the purification module 11, which can accelerate the flow rate of gas entering and exiting the purification module 11.

[0063] In some embodiments, the system further includes an assembly structure 19 adapted to be detachably connected to the vehicle.

[0064] Specifically, such as Figure 6 As shown, the gas purification device assembly 1 also includes an assembly structure 19, which is suitable for detachable connection with the vehicle. It can be, but is not limited to, a magnetic quick-release structure, a snap-on structure, etc., and can be flexibly arranged in any position inside the passenger compartment. This allows users to adjust the system layout according to their needs, while improving the system's versatility and ease of installation. It can also achieve regional gas purification function.

[0065] A second aspect of the present invention provides a gas purification method applied to a gas purification device assembly 1 as described in the above embodiments. The method includes: determining the purified mass parameters of the discharged gas and displaying the purified mass parameters.

[0066] Specifically, such as Figure 7 and Figure 8 As shown, the present invention performs the following steps:

[0067] S1: Determine and display the purified mass parameters of the discharged gas.

[0068] In related technologies, vehicle-mounted gas purification systems typically automatically detect the air quality inside the vehicle and activate the purification function after the vehicle is started. However, for users, the gas purification experience is not noticeable. Therefore, to improve the user's riding experience, this embodiment converts the PM2.5, formaldehyde, toluene, and TVOC characteristic parameters of the gas discharged from the purification module 11 into real-time concentrations and inputs them into the display module 13. This allows users to obtain intuitive and accurate gas quality information, significantly improving the user experience and system usability.

[0069] In some embodiments, the method further includes: determining the current quality parameters of the gas inside the vehicle, and turning the purification module 11 on or off based on the current quality parameters.

[0070] Specifically, such as Figure 8 As shown, the present invention also performs the following steps:

[0071] S2: Determine the current mass parameters of the gas inside the vehicle;

[0072] S3: Turn the purification module 11 on or off based on the current quality parameters.

[0073] To intelligently activate the purification function and achieve energy conservation and emission reduction, this embodiment first needs to determine the current quality parameters of the air inside the vehicle to determine whether the purification module 11 needs to be turned on or off. Further, characteristic parameters of PM2.5, formaldehyde, toluene, and TVOC inside the passenger compartment are collected, and these signal parameters are converted into real-time concentrations and input into the control module 15 to determine whether the conditions for turning the purification module 11 on or off have been met. The real-time concentrations are then input into the display module 13, which displays the air quality before purification in real time.

[0074] In some embodiments, the method includes: activating the purification module 11 when the current quality parameter is greater than the quality threshold.

[0075] Specifically, such as Figure 8 As shown, the present invention also performs the following steps:

[0076] S4: When the current quality parameter is greater than the quality threshold, activate purification module 11.

[0077] The data analysis unit of control module 15 determines the gas quality in the passenger compartment based on preset quality thresholds, including but not limited to PM2.5 (25-75 μg / m³), formaldehyde (0.05-0.1 mg / m³), toluene (0.3-0.8 mg / m³), and TVOC (1-5 mg / m³). When the gas concentration in the passenger compartment is determined to be higher than the quality threshold, it indicates poor gas quality inside the passenger compartment; subsequently, the unit executes the operation of opening the plug 17 and starting the fan 18. At this time, the gas in the passenger compartment is drawn into the purification module 11 for gas purification.

[0078] In some embodiments, the method includes: shutting down the purification module 11 when the current quality parameter is less than or equal to the quality threshold.

[0079] Specifically, such as Figure 8 As shown, the present invention also performs the following steps:

[0080] S5: When the current quality parameter is less than or equal to the quality threshold, shut down the purification module 11.

[0081] The data analysis unit of the control module 15 determines the gas quality in the passenger cabin based on preset quality thresholds, which may include, but are not limited to, PM2.5 thresholds of 25-75 μg / m³, formaldehyde thresholds of 0.05-0.1 mg / m³, toluene thresholds of 0.3-0.8 mg / m³, and TVOC thresholds of 1-5 mg / m³. When the gas concentration in the passenger cabin is determined to be lower than the quality threshold, it indicates that the gas quality inside the passenger cabin is good, and the purification module 11, the first detection module 12, and the second detection module 14 are shut down to achieve energy saving.

[0082] A third aspect of the present invention provides a vehicle including a controller and a gas purification device assembly 1 as described in the above embodiments, wherein the controller is connected to the gas purification device assembly 1 and is used to perform the method as described in the above embodiments.

[0083] In some embodiments, the gas purification device assembly 1 is detachably mounted on the vehicle.

[0084] Specifically, such as Figure 6 As shown, the gas purification device assembly 1 also includes an assembly structure 19, which can be, but is not limited to, a magnetic quick-release structure, a snap-fit ​​structure, etc., and can be flexibly arranged in any position inside the passenger compartment. This allows users to adjust the system layout according to their needs, while improving the system's versatility and ease of installation, and also enabling regional gas purification functions. In a specific embodiment, when the assembly structure 19 is a magnetic structure, there is no need to set up a corresponding matching structure on the vehicle; the gas purification device assembly 1 can simply be attached to a metal surface inside the vehicle. When the assembly structure 19 is a snap-fit ​​structure, a corresponding matching structure is also provided on the vehicle to achieve rapid assembly of the gas purification device assembly 1 on the vehicle.

[0085] In some embodiments, an air conditioning unit is also included, and the gas purification device assembly 1 is selectively connected to the air conditioning unit. When the gas purification device assembly 1 is connected to the air conditioning unit, the gas purification device assembly 1 can be activated when the air conditioning unit is started; however, the gas purification device assembly 1 in the above embodiments depends on the operating status of the vehicle's air conditioning system, and its working mode is limited to the vehicle being started or the air conditioning being on, making independent operation impossible, and the operation process leads to increased energy consumption. In another embodiment of the present invention, the gas purification device assembly 1 is not connected to the air conditioning unit (they are independent of each other), and the gas purification device assembly 1 does not depend on the operating status of the vehicle's air conditioning system. Even when the vehicle is not started, it can still continuously monitor the gas quality in the passenger compartment through built-in sensors to determine whether the gas purification function needs to be activated, so as to ensure that the gas inside the passenger compartment is in a good state for a long time.

[0086] According to embodiments of the present invention, the gas purification module 11, the gas purification method, and the vehicle can purify the gas inside the vehicle and display the quality of the purified gas in real time, enabling users to accurately obtain the quality data of the purified gas and intuitively understand the purification effect. Furthermore, compared to related technologies, this embodiment can be selectively connected to the vehicle's air conditioning system, independent of whether the air conditioning system is turned on or off, and is detachably mounted on the vehicle, allowing for flexible and convenient relocation based on user needs.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
