Technical Field

[0001] This invention relates to the field of automotive air purification technology, and more particularly to an automotive air purification device. Background Technology

[0002] With the development of intelligent and health-oriented automobiles, in-vehicle air purification devices are becoming increasingly common. Their main function is to purify the air entering the vehicle by using filters or disinfection components installed in the car's air conditioning ducts, thereby removing particulate matter, bacteria, viruses, and harmful gases, and improving the air quality inside the vehicle.

[0003] Existing automotive air purification devices typically employ a single-frame structure, housing a filter, UV lamp, or other disinfection components. These devices require insertion into the vehicle's air conditioning duct installation port and securing them inside the vehicle. However, in practice, the dimensions of the duct installation ports vary between different car models. On some models, the installation port width is only half that of the air purification device frame, preventing the single-frame device from being properly inserted into the vehicle and thus hindering installation.

[0004] Therefore, a car air purification device compatible with different sized mounting ports needs to be designed. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," "back," "side," and "circumferential" used in this invention to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," etc., are only used to distinguish multiple components or structures with the same or similar structures and do not indicate any special limitation on the arrangement order or connection relationship.

[0022] Please refer to Figures 1 to 11 This invention provides an automotive air purification device 100 for installation in the air conditioning duct of a vehicle to purify the air within the duct. The automotive air purification device 100 includes a frame 1 and a photocatalytic disinfection component 2.

[0023] The frame 1 includes a first half-frame 11 and a second half-frame 12. The first half-frame 11 and the second half-frame 12 can be inserted sequentially through the mounting port b of the automotive air conditioning duct and spliced ​​together inside the vehicle body, forming a disinfection channel a inside. Understandably, the dimensions of both the first half-frame 11 and the second half-frame 12 are suitable for insertion through the mounting port b. During installation, if the mounting port b is too small to accommodate the entire frame 1, the first half-frame 11 can be inserted first and pushed laterally into one side of the air conditioning duct mounting frame 200, and then the second half-frame 12 can be inserted and spliced ​​together. When the mounting port b is large enough, the two half-frames can be assembled and inserted as a whole, or inserted sequentially and spliced ​​together inside the duct.

[0024] The light disinfection component 2 includes multiple disinfection lamps 21 and a control circuit board 22. The multiple disinfection lamps 21 are respectively disposed inside the first half-frame 11 and the second half-frame 12 and face the disinfection channel a to ensure sufficient light disinfection of the air passing through the disinfection channel a. The control circuit board 22 is disposed in the first half-frame 11 and is used to control the operation of the multiple disinfection lamps 21. Of course, in other embodiments, the control circuit board 22 may also be disposed in the second half-frame 12, or there may be two boards, one in the first half-frame 11 and one in the second half-frame 12, used to control the operation of the disinfection lamps 21 in the first half-frame 11 or the second half-frame 12 respectively; no specific limitation is made here.

[0025] When the first half-frame 11 and the second half-frame 12 are spliced ​​together, the control circuit board 22 and the disinfection lamp 21 are connected. That is, after the first half-frame 11 and the second half-frame 12 are spliced ​​and assembled in the air conditioning duct mounting frame 200, they can drive the disinfection lamp 21 to work according to the received control signal, so as to disinfect and purify the air in the air supply path of the air conditioning duct.

[0026] This allows the car air purification device 100 to be compatible with different sized mounting ports b, significantly improving its installation adaptability and versatility.

[0027] Alternatively, please refer to Figure 5 and Figure 7 In this embodiment, the first half-frame 11 and the second half-frame 12 are connected by the module connection line 4 to achieve circuit connection between the control circuit board 22 and the disinfection lamp 21 when they are spliced ​​together. Of course, in other embodiments, the first half-frame 11 and the second half-frame 12 are electrically connected by conductive terminals at the splicing point when they are spliced ​​together; no specific limitation is made here.

[0028] To address potential issues such as misalignment, unstable connection, or installation difficulties during the assembly of the first half-frame 11 and the second half-frame 12, alternatively, please refer to... Figure 5 , Figure 7 and Figure 9In this embodiment, a linear guide rail 111 is provided between the two splicing ends of the first half-frame 11, and a linear groove c that cooperates with the linear guide rail 111 is provided between the two splicing ends of the second half-frame 12. The second half-frame 12 can slide in along the linear guide rail 111 and splice with the first half-frame 11. That is, the second half-frame 12 can slide in along the linear guide rail 111 of the first half-frame 11 through the linear groove c to complete the splicing with the first half-frame 11. This structure not only simplifies the installation operation, but also ensures the stability of the frame 1 after splicing inside the vehicle body, ensuring that the disinfection channel a is formed completely and firmly. Of course, in other embodiments, a linear groove c can also be provided between the two splicing ends of the first half-frame 11, and a linear guide rail 111 that cooperates with the linear groove c can be provided between the two splicing ends of the second half-frame 12, allowing the second half-frame 12 to slide in along the linear groove c and splice with the first half-frame 11; no specific limitation is made here.

[0029] To ensure a stable electrical connection between the control circuit board 22 of the first half-frame 11 and the second half-frame 12 and the disinfection lamp 21, optionally, please refer to... Figure 7 , Figure 9 and Figure 10 In this embodiment, a module connection line 4 is provided between the first half-frame 11 and the second half-frame 12 to achieve circuit conduction. One end of the module connection line 4 is connected to the splicing end of the first half-frame 11 near the mounting port b, and the other end is connected to the splicing end of the second half-frame 12 away from the mounting port b, so that the wiring extends along the linear groove c as the second half-frame 12 slides in along the linear guide rail 111. That is, when the second half-frame 12 slides into the linear groove c along the linear guide rail 111 of the first half-frame 11, the module connection line 4 extends naturally along the path of the groove without being pulled or interfered with, thus maintaining a smooth wiring arrangement.

[0030] Alternatively, please refer to Figure 10 and Figure 11In this embodiment, the splicing ends of the first half-frame 11 and the second half-frame 12 away from the mounting port b are connected by a snap-fit. Specifically, the splicing end of the first half-frame 11 away from the mounting port b is provided with a snap-fit ​​protrusion 112, and the splicing end of the second half-frame 12 away from the mounting port b is provided with a snap-fit ​​slot d that mates with the snap-fit ​​protrusion 112. When the second half-frame 12 slides along the linear guide rail 111 of the first half-frame 11 to the end of the installation position, the snap-fit ​​protrusion 112 engages with the snap-fit ​​slot d, achieving a stable connection between the ends of the two half-frames away from the mounting port b. Of course, in other embodiments, the splicing end of the first half-frame 11 away from the mounting port b can also be set as the snap-fit ​​slot d, and the splicing end of the second half-frame 12 away from the mounting port b can be set as the snap-fit ​​protrusion 112; no specific limitation is made here. The splicing ends of the first half-frame 11 and the second half-frame 12 near the mounting port b can be fixed by screws 13. That is, after the splicing end away from the installation port b is snapped together, the splicing end near the installation port b is then fixed with screws 13, so that the entire frame 1 is spliced ​​stably and connected firmly in the air conditioning duct.

[0031] Alternatively, please refer to Figure 4 In this embodiment, the frame 1 is a square frame 1. The disinfection lamps 21 are arranged around the inner sides of the first half-frame 11 and the second half-frame 12, with an illumination angle of 120°. Both the first half-frame 11 and the second half-frame 12 include side frames 14 and spliced ​​half-frames 15 connected to the side frames 14. The distance h1 between the illumination intersection angle of two adjacent disinfection lamps 21 on the side frame 14 and the side frame 14 is 1 / 4 to 1 / 3 of the length h2 of the adjacent spliced ​​half-frame 15; the distance h3 between the illumination intersection angle of two adjacent disinfection lamps 21 on the spliced ​​half-frame 15 and the spliced ​​half-frame 15 is 1 / 4 to 1 / 3 of the length h4 of the adjacent side frame 14; specifically, it can be 1 / 4, 3 / 10, or 1 / 3, as long as it is within the range of 1 / 4 to 1 / 3. This forms a high-intensity disinfection light curtain in the central area of ​​the frame 1. Multiple disinfection lamps 21 form an overlapping area in the middle of the frame 1, which is a high-intensity disinfection light curtain, thereby carrying out high-intensity disinfection of the central air supply area of ​​the car air conditioning duct, ensuring uniform and effective air purification.

[0032] To avoid light scattering and installation interference issues with the disinfection lamp 21, optionally, please refer to... Figure 4 and Figure 8 In this embodiment, the disinfection lamp 21 is a UVC ultraviolet lamp embedded in the frame 1. The inner wall of the frame 1 is provided with a concave arc-shaped focusing and avoiding hole o, which is used to avoid and focus the light from the UVC ultraviolet lamp. In this way, the light emitted by the UVC ultraviolet lamp can be concentrated within a 120° range under the action of the concave arc-shaped focusing and avoiding hole o.

[0033] To improve air purification effectiveness, please refer to the following options: Figure 3 , Figure 7 and Figure 9In this embodiment, the side frame of the second half-frame 12 near the mounting port b is provided with a filter element inlet e. It can be understood that the filter element inlet e and the mounting port b of the automotive air conditioning duct are correspondingly provided. The first half-frame 11 is provided with a first protrusion 113 that is flush with the upper surface of the linear guide rail 111 and extends towards the disinfection channel a; that is, the first protrusion 113 and the upper surface of the linear guide rail 111 form a first filter element 31 limiting step. The second half-frame 12 is provided with a second protrusion 121 that is flush with the upper wall of the linear slide groove c and extends towards the disinfection channel a; that is, the second protrusion 121 and the upper wall of the linear slide groove c form a second filter element 32 limiting step.

[0034] The car air purification device 100 also includes a first filter element 31 and a second filter element 32. The first filter element 31 can be inserted into the filter element loading inlet e and is positioned between the first boss 113 and the outer end face of the linear guide rail 111. The second filter element 32 can be inserted into the filter element loading inlet e and is positioned between the second boss 121 and the outer wall of the linear slide groove c. That is, during installation, the first filter element 31 is inserted into the filter element loading inlet e and then pushed laterally into the first filter element 31 positioning step for positioning; then the second filter element 32 is inserted into the filter element loading inlet e and positioned in the second filter element 32 positioning step. It can be understood that, in order to match the filter element loading inlet e, the second filter element 32 is longer than the first filter element 31 in the insertion direction. In this way, it has a dual disinfection effect of light disinfection and filter disinfection, resulting in better air purification effect. Optionally, both the first filter element 31 and the second filter element 32 are MOF filter elements. Of course, in other embodiments, the first filter element 31 and the second filter element 32 may also be HEPA filter elements, activated carbon filter elements, antibacterial coating filter elements or nanofiber filter elements, without specific limitations.

[0035] Alternatively, please refer to Figure 10 In this embodiment, both the first half-frame 11 and the second half-frame 12 include a frame body 16 and a cover plate 17, which are closed to form an assembly cavity. A control circuit board 22 is disposed within the assembly cavity of the first half-frame 11. Multiple lamp panels 23 are respectively provided within the assembly cavities of the first half-frame 11 and the second half-frame 12. The disinfection lamp 21 is fixed to the lamp panel 23 by a lamp panel silicone sleeve 24, preventing the lamp body from loosening due to vibration or airflow. The lamp panels 23 in the first half-frame 11 are connected to the control circuit board 22 via a first FPC board 25; the lamp panels 23 in the second half-frame 12 are connected via a second FPC board 26 and electrically connected to the first FPC board 25 via a module connection line 4. This ensures stable electrical connection between the components within the first half-frame 11 and the second half-frame 12.

[0036] Alternatively, please refer to Figure 10In this embodiment, both the outer sides of the first half-frame 11 and the second half-frame 12 are provided with damping foam 6, which can reduce the vibration and impact received by the car air purification device 100.

[0037] The car air purification device 100 also includes a vehicle body connection 5, which is connected to the control circuit board 22 and led out from the first half-frame 11 for electrical connection to the vehicle's power supply (not shown in the figure) after installation. This allows power to be supplied to the various electronic components within the frame 1, while simultaneously receiving control signals from the vehicle. Of course, in some other embodiments, the car air purification device 100 may also have a built-in power supply; no specific limitation is made here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
