Description

Technical Field

[0001] The utility model belongs to the technical field of air purification equipment development, and relates to a vehicle-mounted road air purification device and an air purification vehicle based thereon. Background Art

[0002] Motor vehicle exhaust is one of the main sources of urban air pollution, emitting a large amount of volatile organic compounds (VOCs) and fine particulate matter (PM2.5). 2.5 ), etc., not only cause serious damage to the environment, but also pose a major threat to human health. Some existing mobile air purification equipment, such as air purification sanitation vehicles, are mainly limited in number, so the purification efficiency and purification capacity are relatively limited. Even with high-power air purification technology and equipment, the efficiency is very low and can only purify the air within the range of the equipment. In order to improve the purification efficiency, a high-power fan needs to be installed, so the noise and energy consumption are relatively large.

[0003] On this basis, researchers have developed a motor vehicle with air purification function that combines a purification device with a mobile carrier such as a motor vehicle used in daily life. Since motor vehicles are used frequently, effective purification of the air can be achieved during the driving process of the vehicle. For example, the Chinese patent application with publication number CN108826462A discloses an air purification device and method based on a mobile carrier, which uses the kinetic energy generated by the mobile device during operation as a driving force to send the air to be purified into the air purification device to purify the ambient air. However, the air purification device is an air purification equipment based on the use of spray dust reduction, including a water tank, a spray device, a spray area, a wastewater collection box, and a water mist collection area. The device has a complex structure, is difficult to maintain on a daily basis, and has a single purification method and limited purification efficiency. The Chinese patent application with publication number CN107906645A discloses an atmospheric air purification device and its system installed on a motor vehicle. The application can purify the air flowing through the device by installing an atmospheric air purification device on the motor vehicle, but the structure of the device is relatively complex. Multiple atmospheric air purification devices are used in a superimposed manner, and the air intake of the air inlet of each purification device is affected. On this basis, the application adds a fan at the air inlet, which undoubtedly increases the cost of equipment modification and use. The Chinese patent with announcement number CN205706077U discloses a vehicle-mounted air purification device, which is installed in the middle of the motor vehicle license plate at the rear of the motor vehicle, but its air intake is limited, and there is a certain angle between the air intake direction and the air outlet direction. Therefore, the gas will generate vortices in the purification device, affecting the effective air intake at the air intake end.

[0004] It can be seen that although the existing air purification equipment combined with mobile carriers can purify polluted air in the environment to a certain extent, it has limited gas enrichment performance and purification capacity. At the same time, the additional equipment creates resistance to vehicle driving, inconvenience in daily maintenance, and cannot effectively monitor the operation of components in the purification device, thereby affecting the user experience.

[0019] A return spring is sleeved on the insertion rod, and the return spring is arranged between the first plate body and the second plate body; fixing parts are also arranged on the insertion rod at both ends of the first plate body.

[0020] An air purification vehicle comprises the above-mentioned vehicle-mounted road air purification device.

[0021] Compared with the prior art, the utility model has the following beneficial technical effects:

[0022] The utility model discloses a vehicle-mounted road air purification device, wherein the first air intake component is the core part of the air intake system, the first air intake component is directly connected to the purification box, and is the main channel for polluted gas to enter the purification box. The design of the first air intake component takes into account the maximum capture of polluted gas in front of the vehicle; in addition, two second air intake components are symmetrically arranged on both sides of the first air intake component, and the arrangement of the second air intake components further widens the air intake area. The second air intake components can capture polluted gas from the front and sides of the vehicle, and increase the overall enrichment capacity of the air intake system. In particular, during the driving process of the vehicle, due to the air flow and the air flow disturbance around the vehicle, the second air intake component can more effectively capture and guide the polluted gas; at the same time, an air intake grille is arranged on the first air intake component, and the two ends of the air intake grille are abutted with the second air intake component. On the one hand, the air intake grille can filter larger particulate matter and improve the purification efficiency, while allowing polluted air to enter and enter the purification box through the first air intake component for purification, and the two ends of the air intake grille are abutted with the second air intake component, so that as much polluted gas as possible can enter the purification box. In summary, the air intake system forms a broad and efficient air intake area through the synergistic effect of the first air intake component, the second air intake component and the air intake grille, thereby improving the gas enrichment capability of the purification device.

[0023] Furthermore, another inventive point of the utility model is that the air intake grille includes a first air intake portion and a second air intake portion which are connected to each other; the first air intake portion and the second air intake portion are both connected to the first air intake assembly, and the windward surfaces of the first air intake portion and the second air intake portion are both provided with a mesh grille. The first air intake portion and the second air intake portion can preferably be vertically arranged. The vertically arranged first air intake portion and the second air intake portion help to optimize the air flow path and reduce turbulence and resistance during air flow. This design allows the air to flow more smoothly before entering the first air intake assembly, thereby improving the air intake efficiency. At the same time, the vertical setting also helps to reduce the adverse effects of wind direction changes on the air intake effect; in addition, the vertically set air intake can also make the air produce a more complex flow pattern when passing through the mesh, thereby increasing the contact opportunities between the particulate matter and the mesh, and further improving the enrichment effect; in addition, the vertically set air intakes can form a mutually supporting structure, which helps to enhance the mechanical strength and stability of the entire air intake grille. During the driving process of the vehicle, the air intake grille will be subjected to forces and vibrations from different directions, and the vertical design can better resist these external factors and ensure the long-term reliability of the air intake grille. In summary, the design of the vertical setting of the first air intake and the second air intake has brought significant beneficial effects in enhancing aerodynamic performance, improving enrichment efficiency and enhancing structural stability. These effects jointly improve the overall performance and reliability of the air intake grille, and provide a more efficient and stable air intake guarantee for the road air purification device installed on the vehicle.

[0024] Furthermore, another inventive point of the utility model is that the connection between the first air intake portion and the second air intake portion and the free end of the second air intake portion are both rounded, and the radius of the rounded corner is 20-30 mm. Firstly, in mechanical design, sharp corners are often high-incidence areas of stress concentration. By setting rounded corners at the connection and the free end, these stresses can be dispersed, significantly improving the stability and durability of the structure; secondly, the rounded corner design reduces the turbulence and eddy current phenomenon when the airflow passes through, thereby reducing the overall airflow resistance and avoiding the impact on vehicle driving; at the same time, reasonable rounded corners The design helps to optimize the air flow path, allowing the airflow to pass through the air intake more smoothly, thereby improving the aerodynamic performance of the entire device, which has a positive effect on improving air purification effects and reducing noise. In addition, 20~30mm is selected as the radius range of the fillet. This range will not take up too much space due to excessive fillet, affecting the compactness of the structure, nor will it fail to fully exert its effect of reducing stress concentration and reducing airflow resistance due to excessive fillet. At the same time, this range also takes into account factors such as material strength, manufacturing process and cost control, ensuring the rationality and economy of the design.

[0025] Furthermore, another inventive point of the utility model is that a first protective plate is also provided at the free end of the second air inlet portion, and the first protective plate is extended to one side of the purification box. The setting of the first protective plate plays an effective protective role for the purification box. This setting can firstly effectively prevent foreign objects such as dust, gravel, branches on the road from directly hitting the purification box and causing damage thereto, thereby ensuring the long-term stable operation of the purification box; in addition, during vehicle driving, especially under harsh road conditions, the protective plate can provide certain protection for the purification box, reducing the risk of damage caused by road bumps or impacts, which is of great significance for extending the service life of the purification device. In addition, the design of the first protective plate helps to guide the airflow to pass through the bottom of the purification device more smoothly, thereby reducing the increase in wind resistance of the vehicle during driving caused by the installation of the purification device.

[0026] Furthermore, another inventive point of the utility model is that guide pipes are symmetrically arranged on both sides of the first air intake assembly, and the guide pipes are connected to the second air intake assembly. First, the setting of the guide pipes can guide the airflow around the vehicle to enter the purification box more efficiently. Especially when the vehicle is traveling at high speed, the airflow is affected by the shape of the vehicle body and the driving speed, and a specific flow pattern will be generated. The guide pipes can capture and utilize these airflows to reduce the loss and turbulence of the airflow, thereby improving the air intake efficiency; secondly, the symmetrically arranged guide pipes help to form a more uniform airflow distribution in the air intake system. When the air enters the second air intake assembly through the guide pipes, its flow rate and direction can be better controlled, reducing the turbulence and eddy current caused by uneven airflow distribution, which helps to improve the purification efficiency of the air purification device and extend its service life; in addition, as a part of the air intake system, the guide pipes can also enhance the structural stability and compactness of the entire air intake system. They can form a stable support structure with the second air intake assembly to reduce the damage to the air intake system caused by vibration and impact generated during the driving of the vehicle.

[0027] Furthermore, the purification box is also provided with an image acquisition component and a display component that communicate with each other. The image acquisition component is arranged inside the purification box, and the display component is arranged outside the purification box. First, the image acquisition component is arranged inside the purification box, and can capture the working status inside the purification box in real time, such as the degree of contamination of the filter element, whether there is foreign matter blocking, etc. This real-time monitoring helps the owner or maintenance personnel to timely understand the operating status of the purification device; secondly, through the image acquisition component, possible faults or abnormal conditions of the purification device can be discovered in time, which helps to take measures in advance to avoid the expansion of faults and ensure the continuous and effective operation of the air purification device; at the same time, the display component is arranged outside the purification box, which is convenient for the user to intuitively view the working status and related information of the purification device. This design improves the user experience, allowing the user to understand the operating status of the internal components of the purification device at any time, thereby more conveniently controlling and using the air purification device.

[0028] Furthermore, another inventive point of the utility model is that a second protective plate is also provided on the top of the purification box, and the second protective plate extends in the direction of the display component. First, the second protective plate provides a physical barrier for the display component, which can effectively prevent external impurities such as rain, dust, mud and sand from directly contacting the display component, thereby protecting it from pollution and damage, which is crucial to ensuring the clarity and long-term stable operation of the display component; in addition, in outdoor environments, strong sunlight and ultraviolet rays may damage the display screen of the display component, resulting in a decrease in display effect or a shortened lifespan. The shielding effect of the second protective plate can reduce direct sunlight and ultraviolet radiation, thereby protecting the display component from these adverse factors; in addition, the second protective plate, as part of the top of the purification box, can enhance the structural stability of the entire purification device. During the driving of the vehicle, especially when encountering bumps or collisions, the protective plate can provide certain support and protection for the display component, reducing the risk of damage. At the same time, the presence of the protective plate also increases the overall safety of the equipment.

[0029] Furthermore, another inventive point of the utility model is that the purification box includes a main body and a bottom plate, and the main body and the bottom plate are detachably arranged. First, the detachable bottom plate allows the user to easily remove the bottom plate, so as to conveniently and thoroughly clean and maintain the inside of the purification box, which is very important for maintaining the hygiene and purification effect inside the purification box. The user can regularly remove the bottom plate to clean the dust, impurities, etc. accumulated at the bottom to ensure the cleanliness of the internal environment of the purification box. In some cases, certain components inside the purification box may need to be replaced regularly to ensure the purification effect. The detachable bottom plate design makes the replacement of these components more convenient. The user does not need to disassemble the entire purification box, but simply removes the bottom plate to replace the components.

[0030] Furthermore, another inventive point of the utility model is that quick-release components are also provided on both sides of the base plate, and the quick-release components include a first plate body and a second plate body arranged in parallel, and a plurality of through holes are provided along the length direction of the second plate body, and each of the through holes is provided with an insertion rod, one end of the insertion rod is detachably arranged with the base plate, and the other end is fixedly connected to the first plate body; a return spring is also sleeved on the insertion rod, and the return spring is arranged between the first plate body and the second plate body; fixing parts are also provided on the insertion rods at both ends of the first plate body. The design of the quick-release component makes the disassembly and assembly process of the base plate fast and simple, and the user only needs to operate the insertion rod to complete the disassembly and assembly process. The installation or removal of the base plate does not require the use of additional tools or complicated steps. This design improves the efficiency of maintaining and replacing the base plate. When the rod passes through the second plate body and is connected to the base plate, the return spring will provide a certain pre-tightening force to ensure a tight connection between the first plate body and the second plate body and between them and the base plate. This stable connection method helps prevent the base plate from loosening or falling off during use; the return spring not only provides pre-tightening force, but also plays a buffering role to a certain extent. When the purification box is subjected to vibration or impact, the return spring can absorb part of the energy and reduce the impact and stress on the base plate and its connecting parts, thereby protecting the base plate and related parts from damage.

[0042] The utility model is further described in detail below with reference to the accompanying drawings:

[0043] like Figure 1 As shown, the utility model discloses a vehicle-mounted road air purification device, including a purification box 1, one end of which is provided with an air intake system, and the other end is provided with an air outlet system 3; the purification box 1 and the chassis of the vehicle are detachable; when the air purification device is installed, the air purification device is installed at the bottom of the vehicle, that is, on the chassis, and the air intake system is arranged close to the air intake grille of the vehicle.

As the vehicle moves, the outside air continuously enters the purification box 1 through the air intake system, and the purified gas can be discharged to the outside through the air outlet system 3, which can be an air outlet pipe. In the purification device, the air intake direction and the air outlet system direction are almost the same, so the vortex of the air flow in the purification box 1 is avoided, the gas circulation is smoother, and the purification efficiency is effectively improved.

[0045] In a feasible solution, the first air intake component 2 can be an air intake pipe, preferably a bellows, which can effectively absorb vibration and impact from the outside, reduce the impact of vibration on the air intake system, and extend its service life; at the same time, it can reduce the vortex and resistance of the airflow, and the noise generated by the air flow.

For the radius of the above-mentioned rounded corner, it can be more preferably 25mm. More preferably, in order to further reduce wind resistance, the air inlet surface of the first air inlet portion 141, that is, the windward surface, can be directly set to an inclined surface or a curved surface, which can further reduce the additional wind resistance generated by the purification device during vehicle driving while improving the gas enrichment capacity, thereby improving the user's experience. In addition, the air inlet grille 14 can also protect the purification box to a certain extent.

[0049] like Figure 2 As shown, in a further preferred scheme, the free end of the second air inlet 142 is also provided with a first protective plate 143, and the first protective plate 143 is extended to one side of the purification box 1, and the orthographic projection of the purification box 1 on the second air inlet 142 is located inside the second air inlet 142, that is, when the purification device is installed on the chassis of the vehicle, the distance between the first protective plate 143 and the ground is less than the distance between the first protective plate 143 and the bottom of the purification box 1, that is, the first protective plate 143 can fully protect the purification box 1. In the preferred scheme, the first protective plate 143 is vertically connected to the second air inlet 142, and the connection method can be welding. The connection between the first protective plate 143 and the second air inlet 142 is also preferably a rounded transition connection to reduce the wind resistance of the vehicle during driving.

[0050] Here, the purification box 1 is also provided with a connecting rod 13, and the air intake grille 14 is fixedly connected to the purification box 1 through the connecting rod 13, which improves the stability of the structure. In addition, in a more preferred solution, two connecting rods 13 can be provided, distributed on both sides of the purification box 1, and the connection stability is stronger.

[0051] The first air intake assembly 2 is also symmetrically provided with flow guide pipes 11 on both sides, and the flow guide pipes 11 are connected to the second air intake assembly 12.

The catalyst in the room temperature nano catalytic coating 22 can decompose some harmful gases, such as nitrogen oxides, sulfur oxides, aldehydes, etc. into harmless substances at room temperature and pressure, thereby reducing the content of harmful gases in the air. The catalyst in the room temperature nano catalytic coating 22 refers to a material that can effectively decompose harmful gases such as nitrogen oxides, sulfur oxides, aldehydes, etc. into harmless substances at room temperature and pressure, thereby improving the air quality. It can be nano metal oxides, such as nano titanium dioxide (TiO2), nano zinc oxide (ZnO) and nano cerium oxide (CeO2); precious metal catalysts, such as platinum (Pt), palladium (Pd), and composite catalysts, such as nano Au / TiO2 composite catalysts. Of course, other nano carbon materials or molecular sieves can also be included. In actual use, different catalytic coating materials have different catalytic mechanisms and applicable scopes. Therefore, when selecting catalytic coating materials, it is necessary to make comprehensive considerations based on specific application scenarios and requirements.

[0057] When the gas in the purification box 1 passes through the activated carbon plate 8, the adsorbed hydroxyl groups on the surface of the activated carbon plate 8 have strong chemical affinity, which can effectively degrade the ozone molecules and prevent them from being further converted into more harmful substances.

[0058] In a preferred solution, in order to facilitate the connection between the purification device and the vehicle, pads 9 are fixedly connected on both sides of the purification box 1, and bolts 10 are provided on the pads 9. When the top of the purification box 1 is in contact with the chassis of the car, the operator can fix the purification box 1 and the chassis of the car to each other by rotating the bolts 10 upwards.

[0059] The working principle of the utility model is:

[0060] First, the operator sets the first air intake component 2 close to the air intake grille of the car. When the car moves, the air in the environment can continuously enter the purification box 1 installed on the chassis of the car through the first air intake component 2, the second air intake component 12 and the air intake grille 14. When the air entering the purification box 1 passes through the high-efficiency filter 6, the fine particles in the air are filtered and purified. When the air passes through the honeycomb aluminum plate 7 and the room-temperature nano-catalytic coating 22 again, some harmful gases in the air are further purified. When the air passes through the activated carbon plate 8 again, the activated carbon plate 8 can effectively reduce the ozone content in the air, and the air after purification and filtration can be quickly discharged from the purification box 1 through the exhaust system 3, thereby realizing effective step-by-step purification of air pollution on the road.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
