[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This vehicle air conditioning refrigeration device uses an impeller installed in the inner cavity of the release cylinder and a permanent magnet installed on the outer wall of the impeller. Driven by the airflow, the impeller rotates in the inner cavity of the release cylinder, thereby driving the permanent magnet. This causes the Hall element to generate a voltage frequency. The rotational speed of the impeller is measured based on the voltage frequency, thereby inferring the air velocity in the inner cavity of the release cylinder. This helps the user to understand the air velocity in the inner cavity of the release cylinder in a timely manner, and thus determine whether the filter element needs to be replaced.

A locking block locks and installs the fixing block and the mounting bracket, ensuring that the mounting bracket is stably fixed in the inner cavity of the filter box. When the mounting bracket needs to be replaced, the locking block moves upward along the outer wall of the limit rod by pushing the push plate upward, thereby unlocking the fixing block. At this time, the mounting bracket is driven by the drive rod, causing the mounting bracket to pop out from the inner cavity of the filter box, which facilitates the disassembly of the mounting bracket.

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.

[0017] Please see Figure 1 - Figure 6The vehicle air conditioning refrigeration unit includes a condenser 1, a cooling fan 2 mounted on the outer wall of the condenser 1, a compressor 3 mounted on the outer side of the condenser 1, an evaporator 4 mounted on the outer side of the condenser 1, a fan duct 5 mounted on the outer wall of the evaporator 4, a connecting pipe 6 mounted on the outer wall of the condenser 1, a filter box 7 fixedly mounted on the outer wall of the evaporator 4 away from the fan duct 5, a release cylinder 8 fixedly mounted on the outer wall of the filter box 7, an impeller 9 rotatably connected to the inner cavity of the release cylinder 8, a Hall element 10 fixedly mounted on the outer wall of the release cylinder 8, a permanent magnet 11 fixedly mounted on the end of the impeller 9 near the permanent magnet 11, a control board 12 mounted on the outer wall of the release cylinder 8, a power supply 13 mounted on the outer wall of the release cylinder 8, and the filter box 7. The inner wall of the filter box 7 is fitted with a limiting plate 14. The inner cavity of the filter box 7 is movably fitted with a mounting bracket 15. The inner cavity of the mounting bracket 15 is fitted with a filter element 16. The outer wall of the filter box 7 is fixedly fitted with a fixing box 17. The outer wall of the mounting bracket 15 near the fixing box 17 is fixedly fitted with a fixing block 18. The inner wall of the fixing box 17 is fixedly fitted with a limiting rod 19. The outer wall of the limiting rod 19 is movably fitted with a first drive spring 20. The outer wall of the limiting rod 19 is movably fitted with a locking block 21. The outer wall of the locking block 21 is fixedly fitted with a push plate 22. The inner wall of the fixing box 17 is fixedly fitted with a limiting cylinder 23. The inner cavity of the limiting cylinder 23 is movably fitted with a drive rod 24. The inner cavity of the limiting cylinder 23 is movably fitted with a second drive spring 25. In the above structure, the release cylinder 8 installed on the outer wall of the filter box 7 can blow the cold air around the evaporator 4 into the inner cavity of the filter box 7 under the action of the air duct 5, and release it into the vehicle through the release cylinder 8. The impeller 9 installed in the inner cavity of the release cylinder 8 will drive the impeller 9 to rotate when there is normal airflow in the inner cavity of the release cylinder 8, thereby causing the impeller 9 to rotate in the inner cavity of the release cylinder 8.

[0018] In a preferred embodiment: the inner cavity of the release cylinder 8 is connected to the inner cavity of the filter box 7, and the installation position of the permanent magnet 11 corresponds to the installation position of the Hall element 10. In the above structure, the permanent magnet 11 set on the outer wall of the impeller 9 will drive the permanent magnet 11 to rotate synchronously when the impeller 9 rotates. Under the action of the permanent magnet 11, the Hall element 10 will generate a voltage signal. As the permanent magnet 11 continues to rotate, the Hall element 10 will generate a continuous voltage frequency. At this time, the rotation speed of the impeller 9 can be calculated based on the voltage frequency, so as to measure the flow rate of the airflow in the inner cavity of the release cylinder 8.

[0019] In a preferred embodiment: the control board 12 is electrically connected to the Hall element 10 and the power supply 13 respectively, the two ends of the outer wall of the first drive spring 20 are in contact with the top of the locking block 21 and the outer wall of the limiting rod 19 respectively, and the first drive spring 20 is made of high carbon steel. In the above structure, a first drive spring 20 is provided on the outer wall of the limiting rod 19. Under the action of the first drive spring 20, the locking block 21 can be driven, so that the locking block 21 moves downward along the outer wall of the limiting rod 19, so that the bottom of the locking block 21 enters the inner cavity of the fixing block 18. At this time, the fixing block 18 can be locked under the action of the locking block 21, so that the fixing block 18 cannot be detached from the inner cavity of the fixing box 17, thereby locking the mounting bracket 15 in the inner cavity of the filter box 7.

[0020] In a preferred embodiment: the outer diameter of the drive rod 24 matches the inner diameter of the limiting cylinder 23, and the end of the drive rod 24 away from the limiting cylinder 23 contacts the outer wall of the mounting bracket 15; In the above structure, the drive rod 24 provided in the inner cavity of the limiting cylinder 23 can drive the locking block 21 to unlock the fixing block 18 when the push plate 22 is pulled upward. At this time, the drive rod 24 can be driven by the second drive spring 25, so that the drive rod 24 can drive the mounting bracket 15 and pop the mounting bracket 15 out of the inner cavity of the filter box 7, thus making it very convenient to remove the mounting bracket 15 from the inner cavity of the filter box 7.

[0021] In a preferred embodiment: the two ends of the outer wall of the second drive spring 25 are in contact with the outer wall of the drive rod 24 and the inner wall of the limiting cylinder 23, respectively, and the second drive spring 25 is made of high carbon steel; In the above structure, the second drive spring 25 installed in the inner cavity of the limiting cylinder 23 is compressed when the drive rod 24 contacts the outer wall of the mounting frame 15. Thus, the second drive spring 25 provides elastic force to the mounting frame 15, popping the mounting frame 15 out of the inner cavity of the filter box 7, so as to facilitate the replacement of the filter element 16 in the inner cavity of the mounting frame 15.

[0022] In a preferred embodiment: there are two limiting cylinders 23, and the two limiting cylinders 23 are respectively movably sleeved in the inner cavity of the two limiting cylinders 23; In the above structure, the limiting cylinder 23 provided on the inner wall of the fixed box 17, under the drive of the second drive spring 25 in the inner cavity of the upper and lower limiting cylinders 23, causes the drive rod 24 to pop out from the inner cavity of the limiting cylinder 23, thereby providing elastic force to the mounting bracket 15, popping the mounting bracket 15 out from the inner cavity of the filter box 7, thus facilitating the removal of the mounting bracket 15.

[0023] In a preferred embodiment: the outer wall shape of the locking block 21 matches the inner wall shape of the fixing block 18, and the push plate 22 passes through the outer wall of the fixing box 17 and is connected to the locking block 21; In the above structure, by using the push plate 22 provided on the outer wall of the locking block 21, when installing the mounting bracket 15, it is only necessary to push the mounting bracket 15 so that the mounting bracket 15 moves along the limiting plate 14, thereby allowing the locking block 21 to enter the inner cavity of the fixing block 18 to lock the fixing block 18. When it is necessary to disassemble the mounting bracket 15, it is only necessary to push the push plate 22 upward to unlock the fixing block 18 and pop the mounting bracket 15 outward.

[0024] Working Principle: During operation, the above-mentioned equipment pushes the air around the evaporator 4 under the action of the air duct 5, allowing low-temperature air to enter the inner cavity of the filter box 7. This low-temperature air is then released into the vehicle through the release cylinder 8, driving the impeller 9 to rotate within the release cylinder 8. This rotation synchronously drives the permanent magnet 11, causing the Hall element 10 to generate a corresponding voltage frequency. The rotational speed of the permanent magnet 11 is proportional to the voltage frequency generated by the Hall element 10. Under the control of the control board 12, the power supply 13 supplies power to the Hall element 10. The rotational speed of the impeller 9 can then be monitored based on the voltage frequency generated by the Hall element 10, thereby monitoring the airflow velocity within the release cylinder 8. This information is provided to assist the user in understanding the airflow. Whether the inner cavity of the release cylinder 8 is properly delivering cold air. Once the filter element 16 becomes clogged, the airflow through the filter element 16 decreases, and the airflow into the inner cavity of the release cylinder 8 also decreases, thereby causing the impeller 9 to rotate slower. This allows for timely detection and replacement of the filter element 16. By pushing the push plate 22 upward, the push plate 22 moves the locking block 21 upward, thereby unlocking the locking block 21 from the inner cavity of the fixing block 18. The second drive spring 25 set in the inner cavity of the limiting cylinder 23 then drives the drive rod 24, causing the drive rod 24 to pop out from the inner cavity of the limiting cylinder 23. The drive rod 24 then provides elasticity to the mounting bracket 15, popping the mounting bracket 15 out from the inner cavity of the filter box 7, thus facilitating the replacement of the mounting bracket 15.
