[0002] With the increasing number of car users and people's growing emphasis on the in-car environment, in-car air purifiers are gaining popularity. In-car air purifiers are specifically designed to purify the air inside cars, removing PM2.5, toxic and harmful gases (formaldehyde, benzene compounds, TVOC, etc.), odors, bacteria, viruses, and other pollutants.
[0003] In use, car air purifiers are typically placed directly on the center console or attached using adhesive tape. While adhesive tape ensures stability, removing it is inconvenient as it requires peeling off the tape. Furthermore, center console-mounted air purifiers are far from the center of the cabin, resulting in poorer air circulation within the vehicle.
[0004] In addition, ordinary car air purifiers rely on the vehicle's power supply for power, which consumes a lot of power. In related technologies, some car air purifiers have added a battery for power, but the purifier needs to be charged repeatedly and recharged in time when the battery is depleted, making it more cumbersome to use.

[0031] See Figure 1 and Figure 5An embodiment of the present invention provides a vehicle-mounted air purification device, comprising: a housing 100, wherein the housing 100 is provided with an air inlet 110 and an air outlet 120 communicating with its inner cavity; the housing 100 is provided with a filter element 200 located between the air inlet 110 and the air outlet 120, and a fan 300 for driving external gas to enter from the air inlet 110 and exit from the air outlet 120; the bottom of the housing 100 is provided with a mounting bracket 400 that does not protrude from the bottom surface of the housing 100; the mounting bracket 400 is detachably mounted with a positioning pin 500 that protrudes downward from the bottom surface of the housing 100 to be inserted into a car cup holder; and a strap assembly 600 that can be wrapped around the mounting bracket 400 is provided.
[0032] The above-described vehicle air purification device can be installed on the cup holder of the center armrest of a car using a detachable positioning post 500 mounted on the mounting bracket 400. After removing the positioning post 500, the device can also be installed on the back of the front seat using the strap assembly 600, providing more installation options. The installation method is very simple and convenient. Compared to traditional installation positions, vehicle air purification devices located on the center armrest or front seat back are more conducive to air circulation, thereby improving the air purification efficiency inside the vehicle. It should be noted that the mounting bracket 400 does not protrude from the bottom surface of the housing 100, thus not affecting the bottom surface of the housing 100's ability to be placed on a flat surface, further providing other placement options. The strap assembly 600 can be a loop of elastic band or a tightening strap.
[0033] See Figure 2 and Figure 3In some embodiments of this utility model, the mounting bracket 400 is provided with a sliding mounting groove 410, the bottom wall of the sliding mounting groove 410 is provided with a positioning slot 420, the positioning insert 500 is provided with a sliding mounting block 510 adapted to the sliding mounting groove 410, the sliding mounting block 510 is connected to an elastic buckle plate 520, and the elastic buckle plate 520 is provided with a positioning protrusion that cooperates with the positioning slot 420. It is understood that the outer diameter of the positioning post 500 matches the inner diameter of the countersunk hole in the cup holder of the car's center armrest. When the positioning post 500 needs to be removed, simply move the elastic buckle plate 520 to disengage the positioning protrusion from the positioning slot 420, and the sliding mounting block 510 can be pulled out of the sliding mounting groove 410. When the positioning post 500 needs to be installed, insert the sliding mounting block 510 along the sliding mounting groove 410 until the positioning protrusion is aligned with the positioning slot 420, and the elastic buckle plate 520 returns to its elastic deformation to lock the positioning protrusion into the positioning slot 420. This design allows for convenient disassembly and installation of the positioning post 500. Of course, in other embodiments, the positioning post 500 can also be detachably connected to the mounting bracket 400 using threaded connections or magnetic attachment.
[0034] See Figure 4 In some embodiments of this utility model, the housing 100 is rectangular, with two air outlets 120 located on the left and right side walls of the housing 100, and an air inlet 110 located on the rear side wall of the housing 100. The fan 300 is a volute fan, with the output ends of the two volute fans facing the two air outlets 120 respectively, and the input ends of the two volute fans facing the filter element 200. The two volute fans being arranged back-to-back helps to increase the efficiency of gas circulation. It is understood that the air intake and exhaust positions are both located on the outer peripheral wall of the housing 100, and the air intake will not be affected when the bottom surface of the housing 100 rests against the back of the car seat or the cup holder of the center armrest, ensuring the air purification effect in the car cabin.
[0035] See Figure 2 and Figure 3 In some embodiments of this utility model, in order to facilitate the replacement of the filter element 200, the housing 100 is provided with a downward-opening mounting cavity for accommodating the filter element 200. The mounting bracket 400 is plate-shaped and is detachably connected to the housing 100 to open or close the opening of the mounting cavity. In order to prevent the filter element 200 from moving relative to the housing when it is located in the mounting cavity, the mounting bracket 400 can clamp and fix the filter element 200 when closing the opening of the mounting cavity.
[0036] See Figure 3In some embodiments of this utility model, at least two insert plates 430 are spaced apart along the extending direction on one side edge of the mounting bracket 400. A mounting through hole 440 is provided on the side of the mounting bracket 400 opposite to the insert plates 430. The housing 100 is provided with slots 130 corresponding to the insert plates 430 and threaded holes 140 corresponding to the mounting through holes 440. Threaded fasteners pass through the mounting through holes 440 and connect to the threaded holes 140. When it is necessary to disassemble the mounting bracket 400 to replace the filter element 200, the threaded fasteners are unscrewed, and then the insert plates 430 are pulled out of the slots 130, making the operation convenient.
[0037] See Figure 4 In some embodiments of this utility model, an air quality detector 700 is provided inside the housing 100, and a disinfection and sterilization component is also provided inside the housing 100. The air quality detector 700, the fan 300, and the disinfection and sterilization component are electrically connected to a control module. The control module can adjust the speed of the fan 300 and control the start and stop of the disinfection and sterilization component. It is understood that the fan 300 operates to drive the air in the vehicle compartment through the air inlet 110, the filter 200, and the air outlet 120 in sequence. When the air quality detector 700 detects that the concentration of formaldehyde, PM2.5, and some harmful gases in the air is too high, the control module increases the speed of the fan 300 and controls the disinfection and sterilization component to work for a certain period of time or continuously. Conversely, when the air quality detector 700 detects that the concentration of formaldehyde, PM2.5, and some harmful gases in the air has decreased significantly, the control module can reduce the speed of the fan 300 and control the disinfection and sterilization component to stop working.
[0038] See Figure 4In some embodiments of this utility model, the disinfection and sterilization component includes a photocatalyst generator 810, an ozone generator 820, and a plasma generator 830. The control module can control the working time of the photocatalyst generator 810, the ozone generator 820, and the plasma generator 830 respectively based on the data measured by the air quality detector 700. The photocatalyst generated by the photocatalyst generator 810 is a general term for photocatalytic semiconductor materials, represented by nano-sized titanium dioxide. Coated on the surface of a substrate, it exhibits strong catalytic degradation under ultraviolet and visible light, effectively degrading toxic and harmful gases in the air, effectively killing various bacteria, and also possessing functions such as formaldehyde removal, deodorization, and air purification. The positive and negative ions generated by the plasma generator 830 release enormous energy instantaneously during the neutralization of positive and negative charges in the air, leading to changes in the structure or energy conversion of surrounding bacteria, thereby causing bacterial death and achieving its sterilization effect. Based on the air quality detected by the air quality detector 700, the photocatalyst generator 810, ozone generator 820, and plasma generator 830 are selectively turned on or off. In this embodiment, the photocatalyst generator 810, ozone generator 820, and plasma generator 830 are respectively equipped with switch buttons for starting and stopping, allowing users to choose freely.
[0039] In some embodiments of this invention, the air quality detector 700 includes a TVOC sensor located near the air inlet 110. The TVOC sensor can detect whether the gas blown in from the air inlet 110 contains alcohol. The control module includes an alarm module electrically connected to the TVOC sensor. It should be noted that the TVOC sensor can sense various organic compounds that can volatilize into gases at room temperature. The main gaseous components include alkanes, aromatics, alkenes, halogens, esters, and aldehydes. If a user cannot determine whether alcohol remains in their body after drinking for a period of time, they can activate the air quality detector 700 by blowing air towards the air inlet 110. If a certain concentration of alcohol is detected, the alarm module will alert the user, thus preventing drunk driving. The alarm module can be an audio player or an LED indicator.
[0040] To avoid relying on the vehicle's jump starter for power, which would cause significant wear and tear on the jump starter, and to avoid the problem of repeated manual charging, see [link to relevant documentation]. Figure 1 and Figure 4In some embodiments of this utility model, a photovoltaic panel 900 is provided on the top surface of the housing 100, and a storage battery 910 electrically connected to the photovoltaic panel 900 is provided inside the housing 100. The storage battery 910 is connected to the wind turbine 300 through a control module. In order to alleviate the problem of insufficient light energy and inability to charge, the control module is also provided with a charging interface connected to the storage battery 910.
[0041] In some embodiments of this utility model, a vibration sensor is provided inside the housing 100. The vibration sensor is electrically connected to the control module so that it can drive the fan 300 and the air quality detector 700 to work when the vehicle starts. When the vehicle starts, vibration is generated, and the vibration sensor transmits a signal to the control module, which then activates the vehicle-mounted air purification device to prevent users from forgetting to use it and to ensure continuous air purification in the vehicle.
[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
