[0032] like Figure 3As shown, specifically, a high-sensitivity formaldehyde sensor 12 and a microcontroller are provided on the outer shell 1. The high-sensitivity formaldehyde sensor 12 is used to monitor the formaldehyde content in the vehicle in real time. When the high-sensitivity formaldehyde sensor 12 detects that the formaldehyde content in the vehicle exceeds a threshold value, the high-sensitivity formaldehyde sensor 12 transmits the information to the microcontroller, and the microcontroller controls the switch of the drive motor 1101. The drive motor 1101 causes the airflow guide component 11 to operate, so that the outer shell 1 is in a negative pressure state, which is used to realize the circulation of air in the vehicle, promote air flow, and realize air circulation. The system can monitor the formaldehyde content in real time, ensure that the air quality in the vehicle is within a safe range, and protect the health of passengers.

[0033] like Figure 3 and Figure 4 As shown, a display screen is provided on the outer shell 1, and the display screen is used to display the monitoring information of the formaldehyde sensor. Specifically, the monitoring information includes the current formaldehyde concentration in the air, historical data trends, and real-time changes in environmental conditions; the display screen adopts a high-brightness LED design and can be clearly seen under various lighting conditions; when the formaldehyde concentration exceeds the set safety threshold, the display screen will flash in a striking red color to alert the user; at the same time, the device will sound an alarm through a built-in buzzer to ensure that the user takes timely measures; in addition, the user can also view detailed data by touching the display screen, such as a historical 24-hour formaldehyde concentration change chart and related suggestions to help improve indoor air quality; for the convenience of user use, the device also supports in-vehicle Wi-Fi connection, which can synchronize data to mobile phone applications, and users can monitor environmental changes anytime, anywhere and perform remote management; such a design not only enhances the user experience, but also improves the practicality and intelligence of the device.

[0034] like Figure 3 and Figure 4 As shown, a built-in power supply is provided inside the outer shell 1, and the built-in power supply is used to power the high-sensitivity formaldehyde sensor 12, the microcontroller, the display screen and the drive motor 1101. The built-in power supply makes the device more independent, does not require interference from an external power supply, and is more convenient for users during use; the integrated built-in power supply can save space in the vehicle, avoid the installation of additional wiring and power adapters, and make the overall layout of the vehicle more concise and beautiful; a charging interface is provided on the outer shell 1, and the charging interface is electrically connected to the input end of the built-in power supply, and the charging interface is electrically connected to the USB interface in the vehicle through a USB data cable. Users can conveniently charge the device through the USB interface in the vehicle without carrying an additional charger or power adapter, which is more flexible to use; the USB interface is a widely used standard interface, and almost all modern vehicles are equipped with a USB interface. This design makes the device compatible with a variety of vehicle models and charging devices.

[0035] like Figure 3and Figure 4 As shown, a partition plate 13 and a movable plate 14 are provided inside the outer shell 1 and along the airflow purification path. The partition plate 13 and the movable plate 14 are arranged in parallel, and the outer edge of the partition plate 13 is fixedly connected to the inner circle of the outer shell 1. A plurality of first positioning holes 15 are provided inside the partition plate 13, and a plurality of second positioning holes 16 are provided inside the movable plate 14. The first positioning holes 15 and the second positioning holes 16 are arranged correspondingly. A plurality of flexible sleeves 17 are provided between the partition plate 13 and the movable plate 14. The flexible sleeve 17 is a hollow structure with openings at both ends. The two ends of the flexible sleeve 17 are respectively connected to the first positioning hole 15 and the second positioning hole 16 to form an airflow channel 18. The airflow on the airflow purification path passes through the plurality of airflow channels 18. The airflow on the airflow purification path is divided into a plurality of airflow channels 18 through the formed plurality of airflow channels 18, which can increase the contact area of ​​the airflow in the purification path, thereby improving the air purification efficiency. ; A plurality of composite purification fibers 19 are arranged in the air flow channel 18 of the flexible sleeve 17, and the composite purification fibers 19 are evenly distributed around the inner circle of the flexible sleeve 17. Specifically, the composite purification fibers 19 are blended by nano-coated fibers, ion exchange fibers and antibacterial and mildew-proof fibers. The nano-coated fibers can effectively capture tiny particles and gaseous pollutants, enhance the adsorption capacity of harmful substances, and help improve the air quality; the ion exchange fibers can effectively remove ionic pollutants in the air and achieve a deeper level of purification; and the antibacterial and mildew-proof fibers can inhibit the growth of bacteria and mold, avoid the formation of biofilms in a humid environment, ensure healthier air quality, and reduce the risk of disease transmission; by blending three fibers of different properties to form a composite purification fiber 19, multiple purification effects can be achieved, for example: removing particles, gas pollution and biological pollutants, and comprehensively improving the effect of air purification.

[0036] like Figure 4As shown, specifically, the flexible sleeve 17 is a bellows-shaped structure, and a plurality of foldable bending portions 20 are formed in the middle of the flexible sleeve 17. An electric telescopic rod 21 is provided between the partition plate 13 and the movable plate 14. The movable plate 14 is telescoped in the outer shell 1 by the telescopic movement of the electric telescopic rod 21. The corrugated structure of the bellows makes it have good flexibility and foldability. When the electric telescopic rod 21 pushes inward, the bellows can be folded along its corrugated portion. The electric telescopic rod 21 is connected between the movable plate 14 and the partition plate 13. The telescopic movement of the movable plate 14 can be realized by electric control. When the movable plate 14 moves toward the partition plate 13, the spacing between the movable plate 14 and the partition plate 13 is reduced, and the foldable portion of the bellows begins to shrink, resulting in a shortened length of the airflow channel 18. This design allows the air to be more concentrated and efficient when flowing through the composite purification fiber 19. As the airflow channel 18 shortens, the composite purification fiber 19 is concentrated, increasing the contact area between the air and these purification materials, thereby improving the purification effect.

[0037] like Figure 4 As shown in the figure, when the electric telescopic rod 21 is pushed outward, the bellows can be unfolded along its corrugated part; at this time, the distance between the movable plate 14 and the partition plate 13 increases, the foldable part of the bellows begins to unfold, the bent part 20 of the bellows is stretched, and the length of the airflow channel 18 is increased; as the bellows unfolds, the airflow channel 18 becomes longer, and when the airflow passes through the extended airflow channel 18, the flow rate increases due to the change in the cross-section of the channel; as the airflow channel 18 becomes longer, the increase in airflow speed is because the area of ​​the channel increases when the system maintains a constant flow rate. Causes the airflow to move over a longer path; in some cases, when the airflow speed is fast enough, the kinetic energy of the airflow can bring a stronger impact force; the impact force of the airflow can vibrate, loosen or directly blow away particulate objects such as dust and pollutants attached to the surface of the composite purification fiber 19, thereby cleaning the composite purification fiber 19; through regular self-cleaning, the performance of the composite purification fiber 19 can be maintained to ensure that its effectiveness will not be reduced due to the accumulation of pollutants during the purification process; clean composite purification fibers 19 can improve filtration efficiency and ensure more effective removal of pollutants in the air.

[0038] like Figure 3 and Figure 4 As shown, the outer edge of the movable plate 14 is connected to the inner circle of the outer shell 1 via a flexible layer 22, which is used to realize the sealed movement of the movable plate 14 inside the outer shell 1. During use, if the internal pressure or shape changes, the flexible layer 22 can adapt to these changes and maintain the normal function of the movable plate 14.

[0039] Working principle: Before use, the user first slides the insertion strip 205 on the outer shell 1 into the slot 204 of the positioning installation strip 201, and clamps the positioning installation strip 201 on the louver in the air outlet of the vehicle air conditioner through the insertion block 202 to achieve the installation of the vehicle-mounted environment detection device, and with the help of the damping shaft 203, the angle adjustment function of the vehicle-mounted environment detection device is achieved.

[0040] Then, the built-in power supply in the vehicle-mounted environment detection device is used to power the vehicle-mounted environment detection device. When the high-sensitivity formaldehyde sensor 12 detects that the formaldehyde content in the vehicle exceeds the threshold value, the high-sensitivity formaldehyde sensor 12 transmits the information to the microcontroller, and the microcontroller controls the switch of the drive motor 1101. Through the drive motor 1101, the airflow guide component 11 is operated, so that the outer shell 1 is in a negative pressure state, which is used to realize the circulation of air in the vehicle, promote air flow, realize air circulation, and form an airflow purification path at the air outlet 4.

[0041] Specifically, the air in the vehicle will pass through the HEPA filter 5, the activated carbon purification plate 6, the negative ion purification plate 7 and the nano material purification plate 8 in sequence along the airflow purification path, thereby achieving the effect of purifying the air in all aspects.

[0042] The purified air will pass through the interior of the flexible sleeve 17 and contact the composite purification fiber 19 inside the flexible sleeve 17. The composite purification fiber 19 is a blend of nano-coated fiber, ion exchange fiber and antibacterial and mildew-proof fiber. The nano-coated fiber can effectively capture tiny particles and gaseous pollutants, enhance the adsorption capacity of harmful substances, and help improve air quality; while the ion exchange fiber can effectively remove ionic pollutants in the air and achieve a deeper level of purification; comprehensively improving the effect of air purification The movable plate 14 is moved in the outer shell 1 by using the electric telescopic rod 21, so as to change the distance between the partition plate 13 and the movable plate 14, so as to further improve the purification effect and the self-cleaning function.

[0043] In addition, a charging interface is provided on the outer shell 1, and the charging interface is electrically connected to the input end of the built-in power supply. The charging interface is electrically connected to the USB interface in the vehicle through a USB data cable. The user can conveniently charge the device through the USB interface in the vehicle without carrying an additional charger or power adapter, which is more flexible to use. The USB interface is a widely used standard interface, and almost all modern vehicles are equipped with a USB interface. This design makes the device compatible with a variety of vehicle models and charging devices.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
