[0018] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0019] Example 1: As Figures 1-7 As shown, this embodiment provides an in-vehicle smoking purification device based on multimodal perception, including a sun visor 1, a purification chamber 2 is provided in the middle of the sun visor 1, a fan 3 is installed at one end of the sun visor 1, an air guide groove 4 is provided between the input end of the fan 3 and the top of the purification chamber 2, and an exhaust port 5 is provided between the output end of the fan 3 and the outer side of the sun visor 1. An exhaust guide mechanism 13 is installed at the end of the exhaust port 5 away from the fan 3 to guide the flue gas toward the sunshade 1. The bottom of the outer side of the sunshade 1 is provided with an air inlet 6 that communicates with the interior of the purification chamber 2, and a first air hole 7 is provided on the outer side of the air inlet 6. A hollow panel 8 is hinged to the bottom of the inner side of the sunshade 1. A second air hole 9 is provided on the outer side of the hollow panel 8. The bottom of the hollow panel 8 is connected to the inside of the air inlet 6 through a connecting hose 10. When the hollow panel 8 is folded, the connecting hose 10 is squeezed, which causes the air passage inside the hollow panel 8 to be blocked. The bottom of the sunshade 1 is provided with a rotating mechanism 11 for driving the hollow plate 8 to rotate; A support mechanism 12 is provided on the top of the inner side of the sunshade 1 to support the sunshade 1 and provide rotation space for the hollow panel 8. The end of the sun shield 1 away from the fan 3 is provided with a control mechanism 14, the control mechanism 14 includes a flame sensor 1401, a PM2.5 sensor 1402 and a controller 1403, the flame sensor 1401 is installed at the bottom end of the sun shield 1 and faces the seat, the PM2.5 sensor 1402 is installed on the outer side of the sun shield 1, and the controller 1403 is installed inside the sun shield 1, the signal output ends of the flame sensor 1401 and the PM2.5 sensor 1402 are in conduction with the controller 1403, and the output end of the controller 1403 is in conduction with the fan 3 and the rotating mechanism 11.

[0020] When there is a smoking behavior in the vehicle, the flame sensor 1401 continuously monitors the smoking flame signal towards the seat area, and the PM2.5 sensor 1402 synchronously collects the air particulate matter concentration data in the vehicle in real time, and both of them will uninterruptedly transmit the monitored signals to the controller 1403. The controller 1403 analyzes and processes the received signals, and when the flame signal of the cigarette ignition is recognized or the PM2.5 concentration reaches the preset trigger threshold, the double control instructions can be autonomously issued without manual operation: on the one hand, a start signal is sent to the fan 3, and the fan 3 forms a negative pressure airflow channel between the air guide groove 4 and the exhaust port 5 after operating, thereby providing power for air circulation and purification; on the other hand, a driving signal is sent to the rotating mechanism 11, thereby triggering the angle adjustment action.

[0021] At the same time of the operation of the rotating mechanism 11, the supporting mechanism 12 responds synchronously with the rotating mechanism 11 through the linkage assembly, thereby stably supporting the sun shield 1, avoiding the interference of the sun shield 1 on the rotation adjustment of the hollow plate 8, and ensuring the smooth work of the air inlet structure.

[0022] During the exhaust process, the exhaust guide mechanism 13 at the top of the seat is manually adjusted, the smoke floating in the vehicle is quickly guided to the direction of the sun shield 1 through the directional guiding action of the exhaust guide mechanism 13, thereby effectively shortening the path of the smoke entering the purification channel. At this time, the external smoke is synchronously sucked into the air inlet cavity 6 through the array distributed first air holes 7 and second air holes 9, enters the purification bin 2 after being conducted through the connecting hose 10, and in the purification bin 2, the airflow sequentially passes through the HEPA filter 201 to filter out fine particulate matter, then passes through the modified activated carbon 202 to adsorb harmful chemical substances such as nicotine and tar, and finally passes through the negative ion generator 203 to release negative ions to optimize air quality, thereby completing three-stage deep purification. The clean air after purification is continuously driven by the fan 3, enters the fan 3 through the air guide groove 4, and is then discharged through the exhaust port 5 and the exhaust pipe 1305, thereby realizing the rapid purification and air circulation of the smoke in the vehicle, significantly reducing the risk of harmful substance diffusion, when the smoke concentration is reduced to below the set threshold and the cigarette end is in the extinguished state, the rotating mechanism 11 controls the hollow plate 8 to reset, the connecting hose 10 is forced to conduct and interrupted, and only the first air holes 7 perform air purification, until the complete purification is completed.

[0023] Embodiment two: the scheme in embodiment one is further introduced in combination with a specific working mode, and details are described below: In this embodiment, the HEPA filter screen 201, the modified activated carbon 202 and the negative ion generator 203 are sequentially arranged in the airflow direction inside the purification bin 2, and the HEPA filter screen 201 and the modified activated carbon 202 are detachably connected with the inner wall of the purification bin 2.

[0024] When the flue gas enters the purification bin 2 through the air inlet cavity 6, the airflow flows through the HEPA filter screen 201, the modified activated carbon 202 and the negative ion generator 203 in the preset direction. The HEPA filter screen 201 can accurately intercept the PM2.5 and other particulate matters in the flue gas due to its high filtration performance; the modified activated carbon 202 can adsorb the volatile harmful chemical substances such as nicotine and tar due to its porous structure; and the negative ions released by the negative ion generator 203 can combine with the small particles remaining in the air to promote the settlement of the small particles and improve the air freshness in the vehicle. The three components form a triple purification synergistic effect to achieve deep purification of the flue gas. In addition, the HEPA filter screen 201 and the modified activated carbon 202 are designed to be detachably connected with the inner wall of the purification bin 2, which facilitates the user to regularly detach, clean or replace them in the later period, thereby ensuring the long-term stable purification effect of the device.

[0025] In this embodiment, the first air holes 7 are arrayed on the inner side wall of the air inlet cavity 6, and the second air holes 9 are arrayed on the surface of the hollow plate 8, and the diameters of the first air holes 7 and the second air holes 9 are consistent.

[0026] When the device is started, the hollow plate 8 is rotated to a preset working angle under the driving of the rotating mechanism 11, and the connecting hose 10 is completely communicated with the air inlet cavity 6, so that the first air holes 7 and the second air holes 9 form a bidirectional collaborative air suction channel. The arrayed structure design greatly increases the contact area between the flue gas and the air holes, and the bidirectional air suction mode can cover a larger range of flue gas diffusion area, so as to ensure that the flue gas dispersed in different positions in the vehicle can be quickly captured and introduced into the purification channel, thereby effectively improving the flue gas collection efficiency.

[0027] In this embodiment, a groove adapted to the hollow plate 8 is formed at the bottom end of the inner side of the sun visor 1, and the hollow plate 8 can be hidden in the groove.

[0028] When the device is not triggered, the hollow plate 8 can be completely hidden in the groove. This design does not occupy additional space in the vehicle, nor does it affect the regular sun-shading function of the sun visor 1, thereby maintaining the cleanliness and aesthetics of the structure in the vehicle; when the device detects the smoking behavior and starts, the rotating mechanism 11 drives the hollow plate 8 to rotate out of the groove, quickly adjusts to the angle for collaborative work with the air inlet cavity 6, and realizes the flexible switching between hidden storage and work deployment.

[0029] In the embodiment, the rotating mechanism 11 comprises a servo motor 1101 and a first shaft 1102, the servo motor 1101 is installed inside the sun visor 1, the signal receiving end of the servo motor 1101 is electrically connected with the controller 1403, the output end of the servo motor 1101 is coaxially fixed with the first shaft 1102, and the first shaft 1102 is fixed along the length direction at the side edge of the hollow plate 8.

[0030] When the controller 1403 issues an angle adjustment instruction, the servo motor 1101 starts immediately after receiving the signal, and the output end thereof is coaxially fixed with the first shaft 1102, so that the first shaft 1102 rotates synchronously with the servo motor 1101. Since the first shaft 1102 is fixed along the length direction at the side edge of the hollow plate 8, the rotating first shaft 1102 drives the hollow plate 8 to rotate around the hinge point thereof with the sun visor 1, so as to adjust the included angle between the hollow plate 8 and the sun visor 1. The extrusion blocking state of the connecting hose 10 is released, so that the second air hole 9 and the first air hole 7 can inhale air at the same time, and the smoke capturing effect is maximized.

[0031] In the embodiment, the supporting mechanism 12 comprises a second shaft 1201, a supporting rod 1202 and a linkage assembly, the second shaft 1201 is rotatably installed at the top inside of the sun visor 1, the supporting rod 1202 is fixedly installed at both ends of the second shaft 1201, and the end of the second shaft 1201 is provided with the linkage assembly with the end of the first shaft 1102.

[0032] The first shaft 1102 controls the rotation of the second shaft 1201 through the linkage assembly. The supporting rods 1202 fixedly installed at both ends of the second shaft 1201 are unfolded outwardly with the rotation of the second shaft 1201, and contact the roof from the top inside of the sun visor 1 to the outside to support the sun visor 1 stably. The linkage design not only provides sufficient space for the rotation adjustment of the hollow plate 8, avoids the collision or interference between the inner wall of the sun visor 1 and the hollow plate 8, but also ensures that the hollow plate 8 always maintains a stable posture during the adjustment process, so as to guarantee the normal play of the air inlet function.

[0033] In the embodiment, the linkage assembly comprises a driving pulley 1203, a driven pulley 1204 and a belt 1205, the driving pulley 1203 is fixed at the end of the first shaft 1102, the driven pulley 1204 is fixed at the end of the second shaft 1201, and the belt 1205 is transmissionally connected between the outer portions of the driving pulley 1203 and the driven pulley 1204.

[0034] The driving pulley 1203 drives the driven pulley 1204 to rotate through the externally transmissionally connected belt 1205, and the driven pulley 1204 is fixedly connected with the second shaft 1201, so that the second shaft 1201 rotates synchronously with the driven pulley 1204.

[0035] In the embodiment, the air exhaust guide mechanism 13 comprises an air exhaust cover 1301, a mounting ring 1302, a rotating rod 1303, a guide plate 1304 and an air exhaust pipe 1305. The air exhaust cover 1301 is mounted on the roof above the seat. The bottom of the air exhaust cover 1301 is horizontally rotatably mounted with the mounting ring 1302 which is in communication with the inside of the air exhaust cover 1301. The inside of the mounting ring 1302 is rotatably mounted with the rotating rod 1303. The rotating rod 1303 is fixed with the guide plate 1304. One end of the air exhaust pipe 1305 is in communication with the air exhaust port 5 and the other end is in communication with the inside of the air exhaust cover 1301.

[0036] When the fan 3 exhausts, the mounting ring 1302 at the bottom of the air exhaust cover 1301 can be horizontally rotated, so that the overall orientation of the guide plate 1304 can be manually adjusted flexibly. At the same time, the rotating rod 1303 inside the mounting ring 1302 can be manually rotated to drive the guide plate 1304 fixed thereon to swing. Through the directional guiding effect of the guide plate 1304, the air flow towards the sunshade 1 is formed, which indirectly pushes the smoke to flow near the first air hole 7 and the second air hole 9, significantly shortens the path of the smoke into the air inlet chamber 6 and improves the smoke circulation rate.

[0037] In the embodiment, the side of the air exhaust cover 1301 is provided with a storage box 1306. The two sides of the storage box 1306 are in communication with the air exhaust cover 1301 and the air exhaust pipe 1305 respectively.

[0038] The storage box 1306 at the side of the air exhaust cover 1301 can store fragrance. The fragrance is diffused into the car along with the purified air flow through the communication structure of the storage box 1306, the air exhaust cover 1301 and the air exhaust pipe 1305, further improving the air smell in the car.

[0039] Embodiment three: the schemes in embodiment one and embodiment two are further introduced in combination with specific working modes, which are described in detail as follows: At the initial stage of the in-vehicle smoking behavior, the flame sensor 1401 continuously and accurately monitors the smoking flame signals in the seat area, and the PM2.5 sensor 1402 collects the in-vehicle air particulate matter concentration data in real time. Both of them continuously transmit the monitored original signals to the controller 1403 for analysis and processing. When the controller 1403 confirms the flame state of the lit cigarette through signal recognition, or detects that the PM2.5 concentration exceeds the preset safety threshold, it immediately starts the synchronous double execution instruction: first, send a start signal to the fan 3, and the fan 3 quickly forms a stable negative pressure between the air guide groove 4 and the exhaust port 5 after running, providing continuous power for the subsequent air circulation and purification process; second, send a precise driving signal to the servo motor 1101, and the servo motor 1101 starts to drive the first shaft 1102 fixed coaxially with it to rotate at a constant speed, which drives the hollow plate 8 fixed on the side to slowly rotate around the hinge point of the sunshade plate 1, so that the hollow plate 8 smoothly rotates out of the adaptive groove on the inside of the sunshade plate 1. At this time, the hollow plate 8 is completely connected with the air inlet cavity 6 through the connecting hose 10, and the arrayed first air holes 7 and second air holes 9 are synchronously opened to form a bidirectional air suction channel, greatly expanding the smoke capture coverage.

[0040] During the rotation of the first shaft 1102, the driving pulley 1203 fixed at the end of the first shaft 1102 rotates synchronously with the first shaft 1102, and the driving pulley 1203 drives the driven pulley 1204 to rotate synchronously through the externally connected belt 1205. The driven pulley 1204 is fixedly connected with the second shaft 1201, and then drives the second shaft 1201 to rotate. The support rods 1202 fixedly installed at both ends of the second shaft 1201 slowly expand with the rotation of the second shaft 1201, and smoothly support from the inside top of the sunshade plate 1 to the outside, supporting the sunshade plate 1 to the preset height, which provides sufficient space for the angle adjustment of the hollow plate 8, avoids collision or motion interference between the inner wall of the sunshade plate 1 and the hollow plate 8, and ensures that the first air holes 7 and the second air holes 9 are always in the best air suction posture without obstruction.

[0041] Under the action of negative pressure, the flue gas is quickly sucked into the air inlet cavity 6 through the first air holes 7 and the second air holes 9, and is smoothly introduced into the purification bin 2 through the connecting hose 10. Inside the purification bin 2, the airflow passes through the HEPA filter 201 in the preset path, efficiently filtering out fine particulate matter in the flue gas; then passes through the modified activated carbon 202, removes harmful chemicals such as nicotine and tar through adsorption; and finally passes through the negative ion generator 203, the released negative ions combine with the small particles remaining in the air to promote sedimentation, while improving air freshness, completing the three-stage deep purification process.

[0042] The purified clean air is continuously driven by the fan 3, enters the fan 3 through the air guide groove 4, and is discharged to the vehicle through the air outlet 5. At the same time, the mounting ring 1302 at the bottom of the air outlet cover 1301 can be manually rotated horizontally and slowly to adjust the overall orientation of the guide plate 1304; and the rotating rod 1303 can be manually controlled to drive the guide plate 1304 fixed thereon to swing flexibly, so that the air flow is formed towards the sunshade board 1 through the directional guiding effect of the guide plate 1304, the air flow trend towards the first air hole 7 and the second air hole 9 is indirectly formed, the path of the smoke entering the purification channel is further shortened, in addition, the fragrance in the storage box 1306 is diffused synchronously with the clean air flow, and the air smell in the vehicle is further optimized.

[0043] When the smoke concentration is reduced to below the set threshold value, and the tobacco head is in an extinguished state, the rotating mechanism 11 controls the hollow plate 8 to reset, the connecting hose 10 is forced to be interrupted, only the first air hole 7 inhales and purifies, until the complete purification is completed.

[0044] The above is only a further embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and concept of the present application within the scope disclosed by the present application, which belongs to the protection scope of the present application.
