Description
Technical Field
[0001] This application relates to the field of sterilization and purification technology, and in particular to a duct-assisted vehicle-mounted sterilization and purification device. Background Technology
[0002] With the increasing popularity of automobiles and the growing prominence of air quality issues, in-vehicle air purifiers have become an important device for improving in-vehicle air quality.
[0003] Currently, most car air purifiers on the market achieve air purification through technologies such as filter adsorption, electrostatic dust collection, or photocatalysis. These technologies each have their own advantages and disadvantages in terms of filtration efficiency, lifespan, and energy consumption, but they generally suffer from problems such as frequent filter replacement and decreased purification efficiency over time. In recent years, the introduction of composite filtration technology and intelligent control systems has improved the purification effect, but it has not completely solved the problems of filter clogging and secondary pollution.

[0028] Reference Figure 1-5 A duct-coordinated vehicle-mounted sterilization and purification device includes a lower outer shell 1 and a base 3. The lower outer shell 1 is installed on top of the base 3. A connecting frame 5 is installed on the inner wall of the lower outer shell 1. A battery module 6 is installed on the top of the base 3. A negative ion module 7 and a formaldehyde module 8 are installed on the inner wall of the connecting frame 5. A supplementary light bead 9 is installed on the top of the connecting frame 5. A filter element 10 is installed on the top of the connecting frame 5. A fan 11 is installed on the top of the filter element 10. A PM2.5 module 12 is fixedly installed on the inner wall of the connecting frame 5. A magnetic suction plate 13 is installed on the top of the connecting frame 5. A magnetic suction module 14 is installed on the outer wall of the magnetic suction plate 13. Multiple clips 15 are installed on the side of the magnetic suction module 14 away from the magnetic suction plate 13. A cover plate 16 is installed on the outer side of the magnetic suction module 14. A display screen 18 is installed on the top of the fan 11.
[0029] See Figure 2 - Figure 5Multiple connecting pipes 4 are fixedly installed on the top of the base 3, and the multiple connecting pipes 4 are all inserted into the inner wall of the connecting frame 5, so that the base 3 can be stably connected to the connecting frame 5, and the bolts can ensure that the base 3 and the connecting frame 5 will not easily separate.
[0030] See Figure 4 and Figure 5 The inner wall of the cover plate 16 is equipped with multiple locking pins 17, and all locking pins 17 are inserted into the inner wall of the cover plate 16. This allows the cover plate 16 to be installed on the outer wall of the magnetic module 14 without the need for fasteners to press it down, which improves the convenience of installation and reduces material waste.
[0031] See Figure 2 and Figure 4 The inner wall of the magnetic module 14 is equipped with a fragrance module, a lighting module, and a sound module. The magnetic module 14 is made of magnetic material, and the magnetic plate 13 is inserted into the inner wall of the magnetic module 14, which allows for quick replacement using the magnetic principle to meet personalized needs. The fragrance module, lighting module, and sound module inside the magnetic module 14 can release fragrance to mask odors, improve comfort, assist in ambient lighting or local lighting in the car, and play white noise and alert sounds.
[0032] See Figure 1 - Figure 3 The upper outer shell 2 is installed on the top of the lower outer shell 1. The upper outer shell 2 is located outside the fan 11, so that it can be used to protect the fan 11, ensuring that it is not directly exposed to the outside, and can improve the overall aesthetics of the device.
[0033] See Figure 2 and Figure 3 A charging port 19 is installed on the top of the connecting frame 5. The charging port 19 and the battery module 6 are electrically connected, so that the charging port 19 can be connected to the charging cable to charge the battery module 6. In turn, the battery module 6 can be used to supply power to the electrical components inside the device.
[0034] See Figure 1 The inner wall of the lower housing 1 has multiple ventilation holes, and the inner wall of the cover plate 16 has multiple slots, allowing air from inside the vehicle to enter the interior of the lower housing 1 for heat dissipation of the electronic components inside the lower housing 1. The slots allow light from the lighting module inside the magnetic module 14 to penetrate to the outside when it is in operation.
[0035] Working principle: First, the PM2.5 module 12 and formaldehyde module 8 continuously detect the PM2.5 and formaldehyde concentrations inside the vehicle. When the PM2.5 and formaldehyde concentrations exceed the standards, the main control board inside the lower outer shell 1 is powered on to start the fan 11, the supplementary light bulb 9, and the negative ion module 7 for disinfection. At this time, air is drawn in by the fan 11 and decomposes organic matter through the filter element 10. The negative ion module 7 assists in settling particulate matter and inhibiting microorganisms. Once purification is complete, the system automatically goes into standby mode when pollutants drop below the standard, and the display screen 18 shows the results.
