Description

Technical Field

[0001] The present invention relates to the technical field of vehicle air purification devices, and specifically, to a vehicle air purification device. Background Art

[0002] The background art of vehicle air purification devices stems from the increasing attention people pay to the air quality inside vehicles. With the acceleration of the urbanization process, the air pollution problem has become increasingly serious, and the vehicle interior environment has inevitably been affected by external pollution sources, such as vehicle exhaust, dust, pollen, bacteria, viruses, and volatile organic compounds. These pollutants not only affect the health of vehicle owners but may also cause problems such as allergies and respiratory diseases. Especially in long - term driving or congested traffic environments, the air quality inside the vehicle is even more important.

[0003] Traditional vehicle air purification devices mostly adopt filter element technology to remove particulate matter in the air through physical filtration. However, this method is only limited to removing larger particulate matter, and the purification effect on gaseous pollutants is relatively limited. With the progress of technology, modern vehicle air purification devices have gradually incorporated auxiliary purification technologies such as negative ions, ozone, and ultraviolet rays, further improving the purification efficiency. In recent years, some high - end vehicle air purification systems have also introduced technologies such as activated carbon and photocatalyst, which can more effectively adsorb harmful gases and decompose toxic substances, providing a fresher vehicle interior air environment.

[0004] However, such vehicle air purification devices still have the following technical problems: Existing air purification equipment is relatively large. In actual operation, the inlet end of the purifier is placed inside the vehicle through a corrugated conduit, and then the air purification equipment is turned on to extract and purify the air inside the vehicle. However, this purification method results in a very limited adsorption area of the vehicle purification device. That is, only when dust settles within the maximum adsorption area around the corrugated pipe can it be adsorbed, thus reducing its use effect. Secondly, regarding the dust - settling effect on suspended particulate matter, the smaller the particulate matter, the longer the required dust - settling time, that is, the vehicle needs to be stationary for a long time. And the insertion of the large corrugated pipe requires the window to be opened, making it difficult for suspended particulate matter to settle, further increasing the working time of the vehicle purification device and reducing its practicality.

[0005] In summary, the existing vehicle air purification devices have a limited adsorption area, reducing the use effect. Secondly, when adsorbing smaller particulate matter, they cannot create a relatively stable stationary space inside the vehicle, resulting in poor purification effect, increasing the operating cost of the device, and reducing the practicality of the device. Summary of the Invention

[0006] The present invention provides a vehicle air purification device, which improves the coverage effect on suspended particles in a larger range inside the vehicle, enhances the air purification efficiency inside the vehicle, thereby improving the purification effect inside the vehicle, shortening the air purification time, and further reducing the operating cost of the device.

[0014] Furthermore, two partition plates are fixedly connected inside the spray housing, and a photocatalyst plate, an ultraviolet lamp tube, a plasma generator and an activated carbon filter plate are fixedly connected in sequence from bottom to top between the two partition plates.

[0015] Furthermore, primary filter components are connected to both sides of the recovery housing. The primary filter components include primary filter housings, with two filter elements detachably and fixedly connected to the primary filter housings. A clamping plate is detachably and fixedly connected to the primary filter housing, and the clamping plate is used for limiting and clamping the two filter elements;

[0016] An air return groove is formed inside the primary filter housing, and the inner wall of the air return groove communicates with the cavities on both sides containing the filter elements. The side of the air return groove facing the spray housing communicates with the inner cavity of the spray housing.

[0017] Furthermore, a dehumidification module is fixedly connected inside the air return groove, and a return water tank is slidably clamped to the lower side of the primary filter housing, and the return water tank communicates with the bottom wall of the air return groove.

[0018] Further, two first air delivery grooves are formed in the side wall of the spray housing, and two second air delivery grooves are formed in the side wall of the recovery housing. The first air delivery groove communicates with the adjacent second air delivery groove.

[0019] Further, the swing module includes:

[0020] A first limit plate and a second limit plate, both the first limit plate and the second limit plate are fixedly connected to the inner wall of the purification housing. Two limit columns are fixedly connected between the first limit plate and the second limit plate. A clamping plate is slidably connected to the two limit columns. A transmission block is fixedly connected to the clamping plate. A micro screw rod is threadedly connected to the transmission block. Two ends of the micro screw rod are respectively rotatably connected to the first limit plate and the second limit plate;

[0021] A slider is fixedly connected to the transmission block. A positioning disk is slidably and rotatably connected to the slider. The positioning disk is rotatably connected to the recovery housing;

[0022] A turning disk is rotatably connected to the first limit plate. A chute is formed in the side wall of the recovery housing. The non - center part of the side surface of the turning disk abuts against the inner wall of the chute;

[0023] A undulating disk is rotatably connected to the second limit plate. A clamping column is fixedly connected to the undulating disk. The clamping column is rotatably connected to the spray housing;

[0026] Further, two positioning grooves are formed in the lower side of the recovery housing. The clamping column abuts against the inner walls of the two positioning grooves.

[0027] The beneficial effects of the present invention are as follows:

[0028] The atomization module can quickly adsorb the tiny particles in the vehicle through the atomized gas, enabling the slow - settling tiny suspended particles to settle more quickly, so as to be adsorbed and purified by the device, shortening the air purification time in the vehicle, further shortening the working duration of the device, and thus reducing the operation cost of the device;

[0029] The efficiency of the recycling module can be adapted to match the working effect of the atomization module. As the atomization range increases, the gas recycling effect changes, ensuring that the suspended particles attached by atomization can be purified faster, improving the purification effect inside the vehicle. The swing module can increase the atomization range. By flipping left and right and using a cyclic atomization method, the atomization area of the atomization module is expanded, thereby improving the coverage effect on suspended particles in a larger range. Secondly, to enhance the attachment effect of suspended particles, the swing module changes the flipping angle of the recycling housing and the flipping method of the atomization module, enhancing the atomization coverage range and significantly improving the attachment effect of suspended particles, and improving the air purification efficiency inside the vehicle. The recycling module, through continuous flipping, rotation, and relative movement, enhances the radiation range and particle attachment effect of the atomization module, thereby improving the air purification efficiency inside the vehicle;

[0030] In summary, through precise motion control, the swing module not only improves the atomization coverage range and the attachment effect of suspended particles, but also, through the cooperation of the recycling module and the atomization module, significantly improves the air purification efficiency inside the vehicle, shortens the air purification time inside the vehicle, shortens the working duration of the device, and thus reduces the operating cost of the device.

Detailed implementation manner

[0040] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present invention.

[0041] Embodiment

[0042] As Figures 1 to 7 shown, this embodiment proposes a vehicle air purification device, including;

[0043] A purification housing 11, and a water storage tank 12 is detachably and fixedly connected to the lower side of the purification housing 11, preferably by press-fit clamping;

[0044] Preferably, a cleaning liquid with improved cleaning effect is added to the water storage tank 12. The cleaning liquid can improve the adsorption effect on fine particles, and at the same time can improve the air quality in the vehicle through the smell of the cleaning liquid itself;

[0045] An atomization module for attaching the cleaning liquid in the water storage tank 12 to the suspended particles outside the purification housing 11 in a spray form. The atomization module includes a spray housing 13, and a plurality of spray plates 14 are respectively fixedly connected to the upper side and the surrounding sides of the spray housing 13. The spray plate 14 is composed of a plurality of spray heads, and a driving assembly for pressurizing the cleaning liquid extracted from the water storage tank 12 is connected in the spray housing 13;

[0046] The atomization module can quickly adsorb the fine particles in the vehicle through the atomized gas, so that the fine suspended particles with slow dust fall can be dusted more quickly, and then be adsorbed and purified by the device, shortening the air purification time in the vehicle, further shortening the working duration of the device, and further reducing the operation cost of the device;

[0047] A recycling module for recycling and purifying the tiny particles adsorbed by atomization. The recycling module includes a recycling housing 15 which is slidably connected to the spray housing 13, and an exhaust fan 16 is fixedly connected to the recycling housing 15;

[0048] A swing module for controlling the amplitude of the left - right flipping of the recycling module and the atomization area of the atomization module;

[0049] The efficiency of the recycling module can be adapted to match the working effect of the atomization module. As the atomization range increases, the gas recycling effect changes, ensuring that the suspended particles attached by atomization can be purified faster, improving the purification effect inside the vehicle. The swing module can increase the atomization range. Through left - right flipping and cyclic atomization methods, the atomization area of the atomization module is expanded, thereby improving the coverage effect on suspended particles in a larger range. Secondly, the attachment effect of suspended particles is enhanced. The swing module enhances the atomization coverage range by changing the flipping angle of the recycling housing and the flipping method of the atomization module, significantly improving the attachment effect of suspended particles, and improving the air purification efficiency inside the vehicle. The recycling module, through continuous flipping, rotation and relative movement, enhances the radiation range of the atomization module and the particle attachment effect, thereby improving the air purification efficiency inside the vehicle;

[0050] In summary, through precise motion control, the swing module not only improves the atomization coverage range and the attachment effect of suspended particles, but also significantly improves the air purification efficiency inside the vehicle, shortens the air purification time inside the vehicle, shortens the working duration of the device, and thus reduces the operating cost of the device;

[0051] A control host 17 for intelligently controlling the atomization module, the recycling module and the swing module respectively. A control cable is connected between the control host 17 and the purification housing 11, and a hole slot for connecting with the corrugated pipe is provided on the control host 17;

[0052] The control host 17 includes an air quality detection sensor. The air quality detection sensor can detect the carbon dioxide concentration, pm2.5 concentration, volatile organic compound concentration and the temperature and humidity inside the vehicle, and then through the main control chip, process and analyze the collected data in a timely manner, and decide whether to send a signal to the driving parts in the swing module. In addition, the control host 17 also includes a wireless transmission module for facilitating users to achieve remote operation. Users can view the current air quality inside the vehicle through their mobile phones;

[0053] In addition, it can also be used in combination with the hole slot on the control host 17 for connecting with the corrugated pipe, so that the vehicle environment can be preliminarily purified first and then statically purified, improving the purification efficiency.

[0054] Such asFigure 5 As shown, both of the two partition plates 21 are fixedly connected inside the spray housing 13, and the photocatalyst plate 22, the ultraviolet lamp tube 23, the plasma generator 24, and the activated carbon filter plate 25 are fixedly connected between the two partition plates 21 in sequence from bottom to top;

[0055] Through the photocatalyst plate 22, the ultraviolet lamp tube 23, the plasma generator 24, and the activated carbon filter plate 25, the adsorbed fine particles are further filtered and purified, improving the overall purification effect of the device.

[0056] As Figures 2 to 6 shown, the primary filter assembly is connected to the recovery housing 15. The primary filter assembly includes a primary filter housing 31. Both of the two filter elements 32 are detachably and fixedly connected to the primary filter housing 31, preferably by threaded connection. The clamping plate 33 is detachably and fixedly connected to the primary filter housing 31, preferably by screw connection. The clamping plate 33 is used to limit and clamp the two filter elements 32;

[0057] An air return groove 34 is opened inside the primary filter housing 31. The inner wall of the air return groove 34 communicates with the cavities on both sides where the filter elements 32 are installed. The side of the air return groove 34 facing the spray housing 13 communicates with the inner cavity of the spray housing 13;

[0058] By providing the two filter elements 32, the primary filter assembly can preliminarily filter and adsorb the larger suspended particles in the vehicle interior, enabling these easily purified particles to be quickly purified. At the same time, some of the fine particles attached to the atomized gas can also be filtered out, reducing the working pressure of the other components in the recovery module and increasing the service life of components such as the photocatalyst plate 22, the ultraviolet lamp tube 23, the plasma generator 24, and the activated carbon filter plate 25.

[0059] As Figures 2 to 6 shown, the dehumidification module is fixedly connected inside the air return groove 34. The water return tank 35 is slidably clamped to the lower side of the primary filter housing 31, and the water return tank 35 communicates with the bottom wall of the air return groove 34;

[0060] Preferably, the dehumidification module uses a micro-compressor and a heat dissipation plate in combination, enabling the water vapor in the recovered air to be preliminarily condensed by the dehumidification module, which can reduce the working pressure of the recovery module. Then, the condensed water droplets can also discharge the attached suspended particles into the water return tank 35 through surface tension. In addition, the water return tank 35 is slidably clamped to the lower side of the primary filter housing 31, facilitating the user to treat the sewage in the water return tank 35, facilitating the user to disassemble and assemble the water return tank 35, and improving the convenience of use of the device.

[0061] As Figures 2 to 6 shown, both of the two first air delivery grooves 131 are opened on the side wall of the spray housing 13, and both of the two second air delivery grooves 151 are opened on the side wall of the recovery housing 15. The first air delivery groove 131 communicates with the adjacent second air delivery groove 151;

[0062] The relative movement between the recovery housing 15 and the spray housing 13 will also change the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151. When the spray module irradiates a larger area, the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151 shrinks. Under the action of the same wind force, the reduced channel area can generate a greater suction force. Furthermore, when the atomization area becomes larger, the efficiency of the recovery module can be adaptively matched with the working effect of the atomization module, ensuring that the suspended particles attached by atomization can be purified faster and improving the purification effect inside the vehicle.

[0063] As Figures 1 to 4 shown, the swing module includes a first limit plate 41 and a second limit plate 42. Both the first limit plate 41 and the second limit plate 42 are fixedly connected to the inner wall of the purification housing 11. Two limit columns 43 are fixedly connected between the first limit plate 41 and the second limit plate 42. A clamping plate 44 is slidably connected to the two limit columns 43. A transmission block 45 is fixedly connected to the clamping plate 44. The transmission block 45 is threadedly connected to a micro screw rod 46. The two ends of the micro screw rod 46 are respectively rotatably connected to the first limit plate 41 and the second limit plate 42;

[0064] A slider 47 is fixedly connected to the transmission block 45. A positioning disk 48 is slidably and rotatably connected to the slider 47. The positioning disk 48 is rotatably connected to the recovery housing 15;

[0065] A turning disk 49 is rotatably connected to the first limit plate 41. A chute 152 is formed on the side wall of the recovery housing 15. The non - center part on the side surface of the turning disk 49 abuts against the inner wall of the chute 152;

[0066] A undulating disk 410 is rotatably connected to the second limit plate 42. A clamping column 411 is fixedly connected to the undulating disk 410. The clamping column 411 is rotatably connected to the spray housing 13;

[0067] A plurality of micro motors 412 are fixedly connected to the first limit plate 41 and the second limit plate 42;

[0068] The user controls the plurality of micro motors 412 in the swing module through the intelligent control host 17. The operation of these motors enables the system to precisely control the actions of the recovery module and the atomization module, achieving a more efficient effect of suspended particle attachment, and thus improving the purification efficiency of the air inside the vehicle;

[0069] First, when the micro-motor 412 coaxially connected to the micro-screw 46 starts, it drives the positioning disk 48 to move to a specified position between the flipping disk 49 and the undulating disk 410. At this time, the micro-motor 412 on the flipping disk 49 starts to work and drives the flipping disk 49 to rotate. The recovery housing 15 flips left and right around the axis of the positioning disk 48, and the atomization module also flips synchronously, changing the single atomization mode of the atomization module into a cyclic left-and-right flipping atomization, thereby expanding the atomization area and improving the coverage effect of atomization on suspended particles in a larger area, and further improving the purification efficiency of the air inside the vehicle;

[0070] As the micro-motor 412 continues to drive the micro-screw 46 to work, the positioning disk 48 further moves towards the flipping disk 49, thereby changing the flipping angle of the recovery housing 15, increasing the flipping amplitude of the recovery housing 15, and further expanding the atomization coverage range of the atomization module. During this process, the effect of the atomization module is strengthened, the atomization range is larger, the adhesion effect of suspended particles is improved, and the purification efficiency of the air inside the vehicle is further improved;

[0071] When the micro-motor 412 coaxially connected to the flipping disk 49 stops working, the system ensures that the side of the recovery housing 15 is perpendicular to the horizontal working surface. At this time, the micro-motor 412 connected to drive the micro-screw 46 continues to work and drives the positioning disk 48 to move towards the undulating disk 410. The positioning disk 48 stops after contacting the side of the undulating disk 410. Then, the micro-motor 412 that controls the rotation of the undulating disk 410 starts to work, and the positioning disk 48 and the undulating disk 410 maintain close contact through the micro-spring 473. As the undulating disk 410 rotates, the recovery housing 15 and the spray housing 13 generate relative movement, further increasing the radiation range of the atomization module on the same area and improving the adhesion effect of the spray module on suspended particles, that is, improving the purification efficiency of the air inside the vehicle.

[0072] As Figures 1 to 4 shown, the positioning post 471 is fixedly connected to the slider 47, the positioning block 472 is slidably connected to the positioning post 471, the positioning block 472 is rotatably connected to the positioning disk 48, the micro-spring 473 is sleeved on the positioning post 471, and the two ends of the micro-spring 473 are respectively abutted against the inner wall of the upper side of the slider 47 and the positioning block 472;

[0073] First, when the positioning disk 48 moves downward and abuts against the side of the undulating disk 410, as the undulating disk 410 rotates, it will drive the positioning disk 48 to move up and down. At this time, the micro lead screw 46 is stationary. Under the action of the micro spring 473, the positioning disk 48 will always abut against the side of the undulating disk 410 during the movement process, thereby causing the recovery housing 15 and the spray housing 13 to move relative to each other. Secondly, when the recovery housing 15 moves downward, the spray plates 14 on the peripheral sides of the spray housing 13 can expose more working areas, enabling the atomization module to irradiate more areas, further improving the adhesion effect of the spray module on suspended particles. In addition, the relative movement between the recovery housing 15 and the spray housing 13 will also change the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151. When the spray module irradiates more areas, the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151 shrinks. Under the action of the same wind force, the reduced channel area can generate a greater suction force. Thus, when the atomization area becomes larger, the efficiency of the recovery module can be adapted and matched with the working effect of the atomization module, ensuring that the suspended particles attached by atomization can be purified faster and improving the purification effect inside the vehicle.

[0074] As Figures 1 to 4 shown, both positioning grooves 153 are opened on the lower side of the recovery housing 15, and the positioning posts 411 abut against the inner walls of the two positioning grooves 153;

[0075] The opening of the two positioning grooves 153 leaves space for the relative movement between the spray housing 13 and the recovery housing 15, so that when the transmission block 45 drives the recovery housing 15 to undulate, it will not interfere with the undulating disk 410, ensuring the stable operation of the device.

[0076] Working principle:

[0077] After the user connects the purification housing 11 to the water storage tank 12 and places it inside the vehicle, then closes the windows, leaving enough space for the power cable of the control host 17. At this time, the interior space of the vehicle becomes a relatively static space. Then, the control host 17 intelligently controls several micro motors 412 in the swing module to work. When the micro motor 412 coaxially connected to the micro lead screw 46 starts to work and drives the positioning disk 48 to move to a stop between the flipping disk 49 and the undulating disk 410, at this time, the micro motor 412 coaxially connected to the flipping disk 49 is driven to work, driving the flipping disk 49 to rotate. The recovery housing 15 will rotate left and right around the axis of the positioning disk 48, and then the atomization module will also rotate left and right accordingly, enabling the atomization module to atomize more areas;

[0078] As the micro-motor 412 coaxially connected to the micro-screw rod 46 continues to operate, driving the positioning disk 48 to move towards the flipping disk 49, the left-right flipping angle of the recovery housing 15 will be changed, making the left-right flipping of the recovery housing 15 greater, further expanding the atomization area of the atomization module and improving the adhesion effect of atomization on suspended particles;

[0079] As the micro-motor 412 coaxially connected to the flipping disk 49 stops operating, after ensuring that the side of the recovery housing 15 is perpendicular to the horizontal working surface at this time, the micro-motor 412 coaxially connected to the driving micro-screw rod 46 operates, driving the positioning disk 48 to move towards the undulating disk 410 until it stops after the positioning disk 48 abuts against the side of the undulating disk 410. Then, the micro-motor 412 that drives the undulating disk 410 to rotate operates. Under the action of the micro-spring 473, the positioning disk 48 always keeps in contact with the side of the undulating disk 410. Thus, the rotation of the undulating disk 410 will cause the recovery housing 15 and the spray housing 13 to move relative to each other, enabling the atomization module to further increase the radiation range area and further improving the adhesion effect of the spray module on suspended particles;

[0080] In addition, the relative movement between the recovery housing 15 and the spray housing 13 will also change the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151. When the spray module radiates more areas, the channel area where the first air delivery groove 131 communicates with the second air delivery groove 151 shrinks. Thus, under the action of the same wind force, a greater suction force can be generated, ensuring that the suspended particles attached by atomization can be purified faster and improving the purification effect inside the vehicle;

[0081] Finally, the user can also connect through the corrugated pipe to the hole groove on the control host 17, and quickly extract the large particles inside the vehicle through the corrugated pipe, reducing the working pressure of other components and further improving the purification efficiency of the air inside the vehicle.

[0082] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
