Description

Technical Field

[0001] This utility model relates to the technical field of vehicle-mounted purification devices, and in particular to a powered vehicle-mounted ozone purification device. Background Technology

[0002] With increasing attention being paid to urban air quality, vehicle-mounted ozone purification devices, as important equipment for improving the outdoor atmospheric environment, are being used more and more widely on public transportation such as buses. These devices, through technologies such as catalytic decomposition, can effectively reduce the concentration of ozone in the atmosphere and reduce photochemical smog pollution, which is of great significance for improving urban air quality and protecting residents' health. In practical applications, vehicle-mounted ozone purification devices need to balance multiple requirements, including purification efficiency, equipment stability, and ease of installation and maintenance.

[0003] Existing powered vehicle-mounted ozone purification devices mostly adopt traditional fixing methods in their structural design, such as fastening the device shell to the roof of the bus with bolts. The technical principle is to open mounting holes at corresponding positions on the device shell and the roof, and use bolts and nuts to firmly fix the device to the roof. During the purification process, the outside air is drawn into the device by the natural flow of the air outlet. The air enters the catalytic module and comes into contact with the catalyst to achieve the decomposition and purification of ozone.

[0004] When existing vehicle-mounted ozone purification devices need to be disassembled, maintained, or replaced, users must use specialized tools such as screwdrivers to unscrew multiple bolts. The entire disassembly process is time-consuming and labor-intensive. Therefore, a powered vehicle-mounted ozone purification device is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A powered vehicle-mounted ozone purification device includes a first outer shell and a second outer shell. One side wall of the first outer shell is slidably connected to the inside of the second outer shell. An air guide plate is fixedly connected inside the second outer shell. A filter screen is fixedly connected inside the second outer shell. A fan is fixedly connected inside the second outer shell. A catalyst box is disposed inside the second outer shell. A fixing component is disposed on the lower surface of the second outer shell. A buffer component is disposed inside the second outer shell.

[0008] The fixing component includes a mounting base located below the second housing. A connecting block is fixedly connected to the bottom of the second housing. The side wall of the connecting block is slidably connected inside the mounting base. A fixing seat is fixedly connected inside the connecting block. A spring is fixedly connected to the side wall of the fixing seat. A locking block is fixedly connected to one end of the spring. The side wall of the locking block is slidably connected inside the connecting block and the side wall of the locking block is slidably connected inside the mounting base.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes a damper, the sidewalls of which are fixedly connected to the interiors of the first and second housings, and one end of the damper is fixedly connected to a placement seat. The sidewalls of the catalyst box are slidably connected to the interior of the placement seat.

[0011] As a further description of the above technical solution:

[0012] The air guide plate is located at the air inlet and air outlet, the filter screen is located behind the air guide plate, the fan is located behind the filter screen, and the catalyst box is located behind the fan.

[0013] As a further description of the above technical solution:

[0014] The catalyst box has multiple through holes inside, and the through holes are filled with catalyst.

[0015] As a further description of the above technical solution:

[0016] Both the outer casing 1 and the outer casing 2 are fixedly connected to a connecting seat, and a connecting rod is fixedly connected to the side wall of the connecting seat.

[0017] As a further description of the above technical solution:

[0022] Both the outer shell and the outer shell sidewalls are fixedly connected to fixing blocks, and screws are threaded inside the fixing blocks.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pre-fixing the mounting base to the roof of the bus, the connecting block is inserted into the mounting base. When the connecting block is inserted into place, the spring pushes the locking block to slide along the inside of the connecting block and lock into the corresponding slot in the mounting base, thereby firmly fixing the outer shell to the mounting base. This achieves a quick installation effect for the device and the roof of the bus, solving the problem that some powered vehicle-mounted ozone purification devices are fixed by bolts, which require other tools to disassemble when disassembly and replacement is needed, which is time-consuming and labor-intensive.

Detailed Implementation

[0035] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-5 This utility model provides an embodiment of a powered vehicle-mounted ozone purification device, comprising a first outer shell 1 and a second outer shell 2, which form an air inlet and an air outlet and serve as a protective structure at the front end of the device, guiding outside air into the device and protecting internal components from external impacts and rainwater erosion. The side wall of the first outer shell 1 is slidably connected to the inside of the second outer shell 2. A guide plate 3 is fixedly connected inside the second outer shell 2 to guide air to enter and exit the device evenly, avoiding turbulent airflow or excessively high local flow velocity, thereby optimizing airflow distribution and improving the contact efficiency between air and catalyst. A filter screen 4 is fixedly connected inside the second outer shell 2 for... To intercept dust, particulate matter and other impurities in the air, the device protects core components and extends its service life. A fan 5 is fixedly connected inside the outer casing 2, a catalytic box 6 is installed inside the outer casing 2, a fixing component is installed on the lower surface of the outer casing 2, and a buffer component is installed inside the outer casing 2. The fan 5 provides power for airflow, draws outside air into the device, and pushes the air through the catalytic box 6 to complete the purification process, thus ensuring that the air continuously and stably passes through the purification device. The fan 5, together with the filter screen 4 and the air guide plate 3, stably delivers air after filtration by the filter screen 4 and air guidance by the air guide plate 3, ensuring the smooth progress of the purification process.

[0037] The fixing components include a mounting base 8, located below the outer casing 2, for fixing to the roof of a bus, providing a mounting base for the entire device. A connecting block 9 is fixedly connected to the bottom of the outer casing 2. The side wall of the connecting block 9 is slidably connected to the inside of the mounting base 8. A fixing seat 10 is fixedly connected inside the connecting block 9. A spring 11 is fixedly connected to the side wall of the fixing seat 10. A locking block 12 is fixedly connected to one end of the spring 11. The side wall of the locking block 12 is slidably connected to the inside of the connecting block 9 and the inside of the mounting base 8. The spring 11 provides elasticity to the locking block 12, allowing it to engage with the slot in the mounting base 8, achieving a stable connection between the outer casing 2 and the mounting base 8. An air guide plate 3 is located at the air inlet and outlet. A filter screen 4 is located behind the air guide plate 3. A fan 5 is located behind the filter screen 4. A catalytic converter box 6 is located behind the fan 5. The box 6 has multiple through holes 7 inside, and the through holes 7 are filled with catalyst. When air flows through the through holes 7, the ozone in them comes into full contact with the catalyst. Under the action of the catalyst, the ozone undergoes a decomposition reaction and is converted into oxygen, achieving the effect of highly efficient ozone purification. The catalytic box 6 works in conjunction with the fan 5. Driven by the fan 5, the ozone-containing air passes through the catalytic box 6 in an orderly manner, ensuring that the ozone is fully decomposed and achieving effective purification of ozone in the atmosphere. The side walls of the outer shell 1 and the outer shell 2 are fixedly connected with fixing blocks 19. The fixing blocks 19 are threaded with screws 20. The screws 20 are used to tightly fix the outer shell 1 and the outer shell 2 together. By tightening the screws 20, the relative position of the outer shell 1 and the outer shell 2 can be adjusted and a stable connection can be achieved, which can ensure the overall structural strength of the device and prevent the outer shell 1 and the outer shell 2 from separating during vibration.

[0038] Reference Figures 6-7The buffer assembly includes a damper 13, used to absorb the vibration energy generated during the bus's operation. It dissipates the vibration kinetic energy through the flow damping of internal hydraulic oil, thereby reducing the vibration amplitude of the catalytic converter box 6. The sidewalls of the damper 13 are fixedly connected to the interiors of outer shell 1 and outer shell 2, respectively. One end of the damper 13 is fixedly connected to a mounting base 21. The sidewall of the catalytic converter box 6 is slidably connected to the mounting base 21. The damper 13 and the mounting base 21 cooperate to provide elastic support for the catalytic converter box 6. Connecting seats 14 are fixedly connected to the interiors of both outer shell 1 and outer shell 2. A connecting rod 15 is fixedly connected to the sidewall of the connecting seat 14. A slider 16 is slidably connected to the sidewall of the connecting rod 15. A connecting strip 18 is rotatably connected to the sidewall of the slider 16. One end of the connecting bar 18 is rotatably connected to the side wall of the placement seat 21. The slider 16 cooperates with the connecting rod 15 to perform linear sliding motion. When the device is subjected to vibration, the slider 16 can slide on the connecting rod 15, and absorb vibration energy by changing its position, thereby achieving the effect of buffering the vibration on the placement seat 21. A second spring 17 is sleeved on the side wall of the connecting rod 15. One end of the second spring 17 is fixedly connected to the inside of the connecting seat 14, and the other end of the second spring 17 is fixedly connected to the side wall of the slider 16. The second spring 17 is used to provide a reset elastic force after the slider 16 slides. When the vibration causes the slider 16 to move, the second spring 17 compresses or stretches to store energy. After the vibration weakens, it pushes the slider 16 to reset, thereby achieving the effect of continuously buffering vibration and maintaining the stability of the device.

[0039] Working Principle: During operation, outside air enters through the air inlet formed by outer casing 1 and outer casing 2. The air guide plate 3 directs the airflow, ensuring even distribution. The air then passes through the filter screen 4, where dust and impurities are filtered out. Subsequently, the fan 5 starts, generating suction to draw in and pressurize the pre-filtered air, propelling it towards the catalytic box 6. The catalytic box 6 has multiple through-holes 7 filled with catalyst. As the air passes through these through-holes 7, the ozone within comes into full contact with the catalyst, catalyzing the process. Under the action of the purifying agent, ozone undergoes a decomposition reaction, transforming into oxygen. The purified air is then discharged through the air outlets of outer casing 1 and outer casing 2, completing the ozone purification process for the external atmospheric environment. Mounting base 8 is fixed to the roof of the bus. When installation is required, the connecting block 9 at the bottom of outer casing 2 is aligned with and inserted into mounting base 8. The connecting block 9 slides within mounting base 8. Once inserted, spring 11 pushes the locking block 12 to slide along the inside of the connecting block 9, locking it into the corresponding slot within mounting base 8, thus securely fixing outer casing 2 to the roof. The device is mounted on the mounting base 8 to secure it to the roof of the bus. During disassembly, pushing the outer shell causes the connecting block 9 to press against the locking block 12, compressing the spring 11 and retracting it into the connecting block 9, allowing the connecting block 9 to be pulled out of the mounting base 8, thus completing the disassembly. When the bus vibrates during operation, the damper 13 absorbs and dissipates the vibration energy, reducing the relative vibration between the outer shell 1 and the outer shell 2. Simultaneously, the placement seat 21, driven by the damper 13, provides buffer protection for the catalytic converter 6. Furthermore, when the device is subjected to vibration, the placement seat 21 drives the connecting strip 18, causing the slider 16 to slide on the connecting rod 15. The spring 17 undergoes compression or stretching deformation, further buffering the vibration and reducing its impact on the catalytic converter 6, protecting the catalyst and internal structure within the catalytic converter 6, and ensuring the stable progress of the catalytic reaction. The side wall of the outer shell 1 is slidably connected to the inside of the outer shell 2. The fixing block 19, which is fixedly connected to the side walls of the outer shell 1 and the outer shell 2, is threaded with screws 20, allowing adjustment and fixation of the relative positions of the outer shell 1 and the outer shell 2 to meet different installation and usage requirements.
