Description

Technical Field

[0001] This utility model relates to the technical field of vehicle air purifiers, and in particular to vehicle negative oxygen ion air purifiers. Background Technology

[0002] In modern society, as people's living standards improve, consumers have higher requirements for the air quality in in-vehicle environments. Especially when vehicles are closed for extended periods or when driving in areas with severe air pollution, pollutants such as suspended particulate matter, harmful gases, and bacteria can easily accumulate, affecting the health of occupants. Therefore, developing in-vehicle devices with air purification functions has become an important requirement for improving the riding experience and protecting passenger health.

[0003] Existing car air purifiers typically purify the air using negative ion generators or filters, but single-function devices have certain limitations in use. For example, traditional negative ion purifiers have limited effectiveness in removing pollutants in a short time, making it difficult to meet the need for rapid purification; while devices with aromatherapy functions often exist independently of the purification device, lacking a collaborative working mechanism, making it difficult to achieve both air purification and aromatherapy diffusion effects simultaneously, and even causing them to interfere with each other, affecting the overall user experience.

[0004] To address the above issues, there is an urgent need for an in-vehicle device that can comprehensively meet the dual needs of air purification and aromatherapy diffusion. This device should utilize an innovative airflow structure design to improve the efficiency of the interaction between negative ions and pollutants, and should be able to achieve time-sharing and zone-based control of negative ion release and aromatherapy diffusion to avoid mutual interference, thereby further enhancing air purification effects and the aromatherapy experience, and meeting users' diverse and comfortable needs for the in-vehicle environment.

[0005] In view of this, the inventor specifically designed a car-mounted negative oxygen ion air purifier, which led to this invention. Utility Model Content

[0006] The purpose of this application is to provide a vehicle-mounted negative ion air purifier, which at least solves the problems of poor air purification effect in the vehicle environment and the mutual interference between aroma diffusion and air purification functions.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This application provides a vehicle-mounted negative ion air purifier, including a housing and a bottom housing. An air inlet is located at the top of the housing, and an air outlet is located on one side of the bottom housing. A centrifugal fan, an annular channel, and a negative ion generator are sequentially arranged within the space where the housing and bottom housing are closed. The centrifugal fan is fitted above the annular channel, and a first air guide is located at the bottom of the centrifugal fan. A second and third air guide are located on the annular channel. The airflow generated by the centrifugal fan flows through the first, second, and third air guides to the air outlet. The negative ion generator is located inside the annular channel. A fragrance component for controlling fragrance release is snapped onto the air inlet, and an air inlet gap is left between the fragrance component and the air inlet.

[0009] In a further embodiment, the annular channel is a ring-shaped cover with a through-hole in the middle, and the negative ion generator is disposed in the through-hole; the second air vent is located at the top, and the third air vent is located on the side.

[0010] In a further embodiment, ear-shaped protrusions are fixedly provided on both sides of the third air duct for connecting and closing the air outlet.

[0011] In a further embodiment, the annular channel is provided with emission holes for the emission of negative oxygen ions.

[0012] In a further embodiment, the first air vent is vertically positioned above the second air vent.

[0013] In a further embodiment, a guide shell is fixedly provided on the outer wall of the centrifugal fan for guiding the airflow through the first air guide port to the second air guide port.

[0014] In a further embodiment, the fragrance component includes an upper cover and a lower cover. The bottom of the lower cover is fixedly provided with a fragrance groove for placing fragrance reagents, and several evaporation holes for fragrance evaporation are formed around the fragrance groove.

[0015] In a further embodiment, the top cover has a connection hole, and a fragrance cap is snapped onto the connection hole.

[0016] In a further embodiment, a rotatable vent valve for controlling the opening and closing of the evaporation vent is fitted onto the outer wall of the fragrance trough.

[0017] In a further embodiment, the vent valve is annular, and control holes of the same shape and number as the evaporation holes are provided around the vent valve.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] Through innovative structural design, a centrifugal fan, annular channel, and negative ion generator are integrated into a synergistic layout within a limited vehicle space, significantly improving the reaction efficiency of negative ions with pollutants in the air. Furthermore, by setting up an air guide structure and multiple air vents to extend the airflow path, the purification effect is effectively enhanced. Simultaneously, a controllable fragrance component enables independent fragrance release, and a mode switching mechanism is achieved through an exhaust valve, avoiding interference between fragrance release and negative ion function. Compared to existing technologies with dispersed purification and fragrance functions, chaotic airflow organization, and bulky structures, this application not only improves air purification efficiency and fragrance diffusion quality but also significantly optimizes interior space utilization and user experience, offering benefits such as compact structure and synergistic function.

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] like Figure 1 As shown, the in-vehicle negative ion air purifier provided in this application includes a housing 1 and a bottom housing 2, which are connected to form a closed structure by means of snaps, screws, or magnetic structures. An air inlet 11 is provided on the top of the housing 1, and an air outlet 21 is provided on one side of the bottom housing 2 to facilitate the flow of air between the inside and outside of the vehicle. This structural design aims to meet the limited space requirements of in-vehicle layout, achieving a compact yet functionally integrated air handling device.

[0038] like Figure 2 and Figure 3 As shown, a centrifugal fan 3, an annular channel 4, and a negative ion generator 5 are sequentially arranged within the internal cavity formed by the outer shell 1 and the bottom shell 2. The centrifugal fan 3 is the driving core of this device. It is installed above and closely connected to the annular channel 4 to ensure that the airflow can flow fully along the annular path. The bottom of the centrifugal fan 3 is provided with a first air guide 31, which is used to guide the intake air downward into the annular channel 4. The top and side walls of the annular channel 4 are respectively provided with a second air guide 41 and a third air guide 42. By adjusting the shape, angle, and number of the air guide structure, the residence time of the air in the channel can be effectively extended, promoting the full reaction of negative ions with pollutants and improving the purification efficiency.

[0039] like Figure 5 As shown, the annular channel 4 in this application has a hollow circular structure with a through hole 43 in its center, which facilitates the placement of the negative ion generator 5 in the center of the annular airflow to achieve omnidirectional treatment of the incoming gas. Several emission holes 45 are also provided on the outer wall of the channel to optimize the release path of negative ions and improve their coverage.

[0040] like Figures 1 to 3As shown, to address the issue of mutual interference between air purification and fragrance release during practical use, this application designs a time-sharing and zone-based control mechanism and adds a controllable fragrance component 6 to the air inlet 11 structure. The fragrance component 6 is installed above the air inlet 11 via a snap-fit ​​method, including an upper cover 61 and a lower cover 62 for easy replacement and cleaning. The bottom of the lower cover 62 has a fragrance groove 63 for holding fragrance reagents. The fragrance groove 63 has several evaporation holes 64 around its perimeter, enabling uniform diffusion of fragrance during fan extraction. Simultaneously, a rotatable air outlet valve 7 is provided on the outer wall of the fragrance groove 63. This valve has a circular structure with control holes 71 around its perimeter corresponding to the shape and number of evaporation holes 64. By rotating this air outlet valve 7, the user can manually adjust the fragrance release intensity or turn off the fragrance function, thereby switching between air purification and fragrance diffusion modes. The top cover 61 has a connection hole 65, and a fragrance cover 66 is snapped onto the connection hole 65, which can further adjust the overall air intake to control the degree of fragrance release.

[0041] like Figure 4 and Figure 6 As shown, in addition to further optimizing the air duct structure, a guide shell 32 is also provided on the outer wall of the centrifugal fan 3 to guide the airflow from the first air guide port 31 to the second air guide port 41, thereby strengthening the annular flow trend of the airflow within the duct. This air guiding design, combined with the vertically arranged air guide port structure, allows the airflow to circulate within the annular path for a long time, improving air purification efficiency.

[0042] like Figure 4 and Figure 5 As shown, in the air outlet 21 area of ​​the bottom shell 2, ear-shaped connecting ears 44 are integrally provided on both sides of the third air guide 42. These connecting ears 44 and the third air guide 42 form a gradually narrowing airflow channel. This structure effectively guides the airflow discharged from the annular channel 4 to converge and flow smoothly towards the air outlet 21, avoiding problems such as turbulence, backflow, or diffusion loss during the exhaust process, thereby improving the overall air purification and fragrance release efficiency. The connecting ears 44 not only serve as airflow guides and rectifiers, but their structural form (such as curvature, angle, and outlet size) can also be optimized to further adjust the airflow speed and distribution, providing a more comfortable and uniform airflow experience for vehicle occupants.

[0043] Through the above structural configuration, this application not only improves the purification efficiency of the in-vehicle air purifier, but also effectively solves the conflict between the fragrance function and the purification function, meeting the user's dual needs for air quality and environmental experience in the limited in-vehicle space.

[0044] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
