Description

Technical Field

[0001] This utility model relates to the field of vehicle cabin air purification technology, and in particular to an air purification device for vehicle cabins. Background Technology

[0002] Currently, refrigerated trucks and refrigerated transport vehicles, due to their prolonged operation in a sealed environment, suffer from poor air circulation, making them prone to the growth of bacteria, mold, and other microorganisms, and potentially accumulating odors or volatile organic compounds (such as ethylene and other metabolic gases from fruits and vegetables). Traditional air purification methods mainly rely on forced ventilation systems or electrically driven air purification devices, but these solutions have the following problems in refrigerated environments:

[0003] High energy consumption: Refrigerated truck compartments themselves require continuous cooling, and adding additional electrically driven ventilation or purification equipment will increase energy consumption and affect the driving range;

[0004] Inconvenient maintenance: The interior space of refrigerated trucks is compact, and traditional fixed filters are difficult to install and remove, resulting in low efficiency.

[0005] Therefore, an air purification device for train carriages is proposed. Utility Model Content

[0006] This utility model is a vehicle cabin air purification device proposed to overcome the shortcomings of the existing technology.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an air purification device for a vehicle compartment, comprising a vehicle compartment body, wherein a ventilation pipe extending into the interior is sealed and fixedly connected to the top of the vehicle compartment body, a gate-shaped tube is fixedly connected to the top of the ventilation pipe, a bearing seat is fixedly embedded in the top of the gate-shaped tube, a wind cup is fixedly connected to the inner ring of the bearing housing, and an exhaust impeller is fixedly connected to the bottom of the mounting shaft of the wind cup, and the exhaust impeller is disposed inside the vehicle compartment body;

[0008] Both sides of the inner surface of the portal tube are fixedly connected to return air pipes, and the return air pipes are fixedly interconnected with the carriage body.

[0009] The bottom of both return air ducts is installed with a housing together with the bottom of the gate-shaped duct. The inner walls on both sides of the two housings are fixedly connected with partitions. The top of the two partitions and the top of the adjacent housing are jointly supported by activated carbon filter components, and the activated carbon filter components are located below the gate-shaped duct.

[0010] Both partitions are connected to adjacent housings by a lamp sterilization assembly.

[0011] Both housings are connected to a screw lifting assembly between the gantry pipe and the adjacent return air pipe, and both screw lifting assemblies are equipped with limit handwheels at their drive ends.

[0012] Furthermore, the bottom of both return air ducts is fixedly connected with a first return-type sealing gasket, and the first return-type sealing gasket is in sealed contact with the adjacent housing and partition. This structure effectively prevents air leakage during the circulation process.

[0013] Furthermore, both activated carbon filter components include mounting rings, which are mounted on top of adjacent partitions and the housing. A second loop-shaped sealing gasket is fixedly connected to the top of the mounting ring, and the second loop-shaped sealing gasket seals against the gate-shaped tube. A stainless steel filter screen is fixedly connected to the bottom of the mounting ring. An activated carbon filter layer is sleeved on the outer surface of the stainless steel filter screen, and an external stainless steel support mesh is sleeved on the outer surface of the activated carbon filter layer. The external stainless steel support mesh is fixedly connected to the mounting ring. This multi-layer filtration structure design not only ensures the reliability of filtration but also facilitates later maintenance and replacement.

[0014] Furthermore, both of the aforementioned lamp sterilization components include two quartz glass plates, which are fixedly embedded on both sides of adjacent partitions. Multiple ultraviolet lamps are provided between the two quartz glass plates, and the ultraviolet lamps are fixedly connected to the adjacent partitions. On one side of the vehicle body, multiple quartz glass strips are arranged between a single quartz glass plate and the adjacent shell, and the quartz glass strips are fixedly connected to the shell. The high light transmittance of quartz glass maximizes the ultraviolet sterilization effect, and its low-temperature resistance is particularly suitable for use in refrigerated vehicle environments.

[0015] Furthermore, both screw lifting assemblies include two screw bodies, which penetrate the housing and are rotatably connected to it. The outer surfaces of both screw bodies are threaded with connecting blocks, which are fixedly connected to the gantry pipe and the adjacent return air pipe. The bottom of both screw bodies is fixedly connected with synchronous pulleys, and a synchronous belt meshes between the two synchronous pulleys. This synchronous lifting mechanism ensures the stable movement of the housing.

[0016] Furthermore, both of the aforementioned limit handwheels include a turntable, and the turntable is fixedly connected to the adjacent synchronous pulley. The bottom of the turntable is provided with a handle extending through to the top, and the handle is slidably connected to the turntable. The top of the handle is fixedly connected to a limit block, and the bottom of the limit block and the turntable are both fixedly connected to a spring. This design realizes the function of quick locking and unlocking, and the elasticity of the spring ensures the tight fit between the limit block and the limit groove.

[0017] Furthermore, both housings have limit grooves at their bottoms, and these limit grooves match the limit blocks. This limiting structure provides a limiting basis for the lifting assembly, preventing the turntable from rotating during vehicle operation.

[0018] The beneficial effects of this utility model are:

[0019] In use, this utility model provides an in-cabin air purification device that uses a fan cup to drive an exhaust impeller, utilizing the natural wind power during vehicle movement to achieve unpowered ventilation. This reduces energy consumption and continuously promotes air circulation inside and outside the cabin while the vehicle is in motion. The combined design of the vent-shaped duct and return air duct creates an airflow path. Combined with activated carbon filter components and ultraviolet lamp sterilization components, it effectively filters dust and odors from the air and kills bacteria, significantly improving the air quality inside the vehicle cabin.

[0020] When in use, this utility model is an air purification device for a vehicle compartment. The screw lifting assembly, combined with the design of the limiting handwheel, allows for easy adjustment of the distance between the housing and the gate-shaped tube, and enables quick disassembly and replacement of the activated carbon filter assembly during maintenance.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 6 As shown, an air purification device for a vehicle compartment is disclosed, comprising a vehicle compartment body 1. A ventilation duct 3 extending into the interior is sealed and fixedly connected to the top of the vehicle compartment body 1. A portal-shaped tube 2 is fixedly connected to the top of the ventilation duct 3. A bearing seat 6 is fixedly embedded in the top of the portal-shaped tube 2. An air cup 4 is fixedly connected to the inner ring of the bearing within the bearing seat 6. An exhaust impeller 9 is fixedly connected to the bottom of the mounting shaft of the air cup 4, and the exhaust impeller 9 is located inside the vehicle compartment body 1. A sealing ring is provided at the fixing point between the ventilation duct 3 and the portal-shaped tube 2 to ensure the sealing between them. The air cup 4 is made of lightweight aluminum alloy and its surface is anodized to improve weather resistance. The bearing within the bearing seat 6 is sealed using existing packing to ensure the sealing of the bearing within the bearing seat 6.

[0032] Both sides of the inner surface of the portal tube 2 are fixedly connected to return air pipes 7, and the return air pipes 7 are fixedly interconnected with the carriage body 1.

[0033] The bottom of both return air ducts 7 is installed with the bottom of the door-shaped duct 2 together with the housing 5. The bottom of both return air ducts 7 is fixedly connected with the first return air sealing gasket 22, and the first return air sealing gasket 22 is sealed and abutted against the adjacent housing 5 and partition 21. The inner walls on both sides of the two housings 5 ​​are fixedly connected with the partition 21.

[0034] Both partitions 21 and the top of the adjacent shell 5 are equipped with activated carbon filter components, which are located below the portal tube 2. Both activated carbon filter components include mounting rings 24, which are mounted on the top of the adjacent partitions 21 and shell 5. A second loop-shaped sealing gasket 23 is fixedly connected to the top of the mounting ring 24, and the second loop-shaped sealing gasket 23 is in sealing contact with the portal tube 2. A stainless steel filter screen 25 is fixedly connected to the bottom of the mounting ring 24. An activated carbon filter layer 26 is sleeved on the outer surface of the stainless steel filter screen 25. An external stainless steel support net 27 is sleeved on the outer surface of the activated carbon filter layer 26, and the external stainless steel support net 27 is fixedly connected to the mounting ring 24. The activated carbon filter layer 26 is 50mm thick and is filled with coconut shell activated carbon particles with a particle size of 2-4mm and an iodine value ≥1000mg / g, which has a good adsorption effect.

[0035] Both partitions 21 are equipped with lamp sterilization components between themselves and the adjacent housing 5. Each lamp sterilization component includes two quartz glass plates 19, which are fixedly embedded on both sides of the adjacent partition 21. Multiple ultraviolet lamps 20 are provided between the two quartz glass plates 19, and the ultraviolet lamps 20 are fixedly connected to the adjacent partitions 21. On one side of the carriage body 1, multiple quartz glass strips 18 are arranged between a single quartz glass plate 19 and the adjacent housing 5, and the quartz glass strips 18 are fixedly connected to the housing 5. The thickness of the quartz glass plate 19 is 3mm, and the ultraviolet light transmittance is ≥90%. The quartz glass strips 18, housing 5, and quartz glass plates 19 can be combined to form an S-shaped flow channel to increase the air residence time and improve the contact time between the light and air of the ultraviolet lamps 20.

[0036] Both housings 5 ​​are connected to the portal duct 2 and the adjacent return air duct 7 by screw lifting assemblies. Each screw lifting assembly has a limit handwheel at its drive end. Each assembly includes two screw bodies 10, which penetrate the housing 5 and are rotatably connected to it. This rotatable connection is achieved using bearing seats. The bearing seat is fixed to the housing 5, and the inner ring of the bearing inside the bearing seat is fixed to the screw body 10. Connecting blocks 8 are threaded onto the outer surfaces of both screw bodies 10. The thread helix angle of the screw body 10 is less than the friction angle, giving it self-locking capability and preventing displacement due to vibration or load. The connecting blocks 8 are fixedly connected to the portal duct 2 and the adjacent return air duct 7. The bottoms of both screw bodies 10 are fixed. The device is connected to a synchronous pulley 11, and a synchronous belt 12 is meshed between the two synchronous pulleys 11. Both limit handwheels include a turntable 17, and the turntable 17 is fixedly connected to the adjacent synchronous pulley 11. The bottom of the turntable 17 is provided with a handle 16 that extends through to the top, and the handle 16 is slidably connected to the turntable 17. The top of the handle 16 is fixedly connected to a limit block 14, and the bottom of the limit block 14 is fixedly connected to the turntable 17 with a spring 15. The bottom of both housings 5 ​​is provided with a limit groove 13, and the limit groove 13 matches the limit block 14. The spring 15 is a stainless steel compression spring with a stiffness coefficient of 8 N / mm and a pre-compression amount of 10 mm, which facilitates pulling the handle 16 while ensuring that the limit block 14 is always embedded in the limit groove 13 when there is no external force.

[0037] Working Principle: When the vehicle is in motion, the external airflow drives the fan cup 4 to rotate, which in turn drives the exhaust impeller 9 to rotate synchronously, creating a negative pressure inside the vehicle body 1. This causes the air inside the vehicle to sequentially enter the vent pipe 2 through the exhaust pipe 3, and then enter the housing 5. After entering the housing 5, the air first passes through the activated carbon filter assembly, where it undergoes primary filtration by the stainless steel filter screen 25. The activated carbon filter layer 26 adsorbs odors and harmful gases, while the external stainless steel support mesh 27 ensures the stability of the filter layer structure. Subsequently, the air flows through the lamp sterilization assembly, where the ultraviolet lamp 20 irradiates and sterilizes the air through the quartz glass plate 19 and quartz glass strip 18. Finally, the purified air re-enters the vehicle body through the return air pipe 7, forming a circulating purification system. The screw lifting assembly drives the synchronous pulley 11 and the screw body 10 to rotate by turning the handle 16. Since the connecting block 8 is fixedly set, it causes the housing 5 to descend, facilitating the disassembly and replacement of the activated carbon filter assembly during maintenance. The limit block 14 is engaged in the limit groove 13 under the action of the spring 15, ensuring stable locking after the lifting position is reached. The entire system is driven by the natural wind power when the vehicle is moving, and can achieve continuous air purification and sterilization without the need for additional energy.

[0038] It should be noted that, in actual use, an existing technology controller can be added. The controller is electrically connected to the ultraviolet lamp 20 to facilitate the operation of the ultraviolet lamp 20.
