[0026] 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.

[0027] Reference Figure 2 , Figure 3 and Figure 5 As shown, one embodiment of this utility model provides a refrigerant circulation mechanism for an air-cooled inverter air conditioner, including a housing 1, a connecting plate 3 on the inner wall of the housing 1, a filter plate 4 fixedly connected to the rear end of the connecting plate 3, slots 9 on both sides of the inner wall of the housing 1, and a locking block 8 on the inner wall of each slot 9, the shape of the locking block 8 fitting the slot 9, the outer wall of each locking block 8 slidingly connected to the inner wall of the connecting plate 3, a sliding frame 6 slidingly connected to the inner wall of the connecting plate 3, a rotating rod 7 rotatably connected to both sides of the inner wall of the sliding frame 6, the other end of each rotating rod 7 rotatably connected to the inner wall of the locking block 8, and a threaded rod 5 threadedly connected to the inner wall of the sliding frame 6, the rear end of the threaded rod 5 rotatably connected to the inner wall of the connecting plate 3 for the installation and removal of the filter plate 4.

[0028] Specifically, during installation, simply insert the filter plate 4 into the outer casing 1 and rotate the threaded rod 5 in the opposite direction to insert the locking blocks 8 on both sides into the slots 9 to complete the installation. The filter plate 4 is made of stainless steel. The working principle of the refrigerant circulation mechanism body 2 is that the system has two independent refrigerant circulation flow modes: the refrigerant pump operation mode and the compressor operation mode. When the refrigerant pump is running, the low-temperature liquid refrigerant is discharged from the refrigerant pump outlet, passes through the one-way valve, and absorbs heat from the indoor side through the EXV1 throttling to evaporate. After evaporation, the refrigerant becomes gaseous refrigerant and returns to the outdoor side. It exchanges heat with the low-temperature air on the outdoor side and condenses into liquid refrigerant, which then passes through the refrigerant pump inlet to form a circulation flow. A pressure sensor is added to the refrigerant pump outlet. The operating status of the refrigerant pump is monitored by the pressure difference between the high-pressure sensor port and the refrigerant pump outlet pressure sensor. The refrigerant pump is controlled and protected accordingly based on the pressure difference. A special gas-liquid separator ensures that the compressor draws in gas when it is running. When the refrigerant pump is running, the gas-liquid separator does not retain liquid to ensure that more refrigerant participates in the heat exchange cycle. The liquid receiver is used to ensure that the refrigerant pump draws in liquid refrigerant to ensure the stable and reliable operation of the refrigerant pump. By rotating the threaded rod 5, the limiting position on the filter plate 4 and the connecting plate 3 can be released, and the filter plate 4 at the air inlet of the refrigerant circulation mechanism body 2 can be disassembled. No tools are required, the operation is simple, it can avoid the scattering and contamination of impurities, facilitate frequent cleaning or replacement, adapt to different environments, reduce maintenance costs, and ensure the efficient operation of the mechanism.

A pull rod 14 is slidably connected to the inner wall of the fixed handle 12. A collection frame 13 is fixedly connected to the right end of the fixed handle 12. A refrigerant circulation mechanism body 2 is fixedly connected to the inner wall of the outer casing 1. A limiting groove 18 is opened on the inner wall of the outer casing 1. A limiting block 17 is provided on the inner wall of the limiting groove 18. The shape of the limiting block 17 matches the limiting groove 18. The outer wall of the limiting block 17 is slidably connected to the inner wall of the fixed handle 12. A transmission rod 16 is rotatably connected to the inner wall of the pull rod 14. The other end of the transmission rod 16 is rotatably connected to the inner wall of the locking block 8. A spring 15 is fixedly connected to the inner wall of the pull rod 14. The other end of the spring 15 is fixedly connected to the left end of the fixed handle 12. A linear motor 10 is fixedly connected to the inner wall of the outer casing 1. A scraper 11 is slidably connected to the outer wall of the linear motor 10. The right end of the scraper 11 is located at the left end of the filter plate 4 for cleaning the filter plate 4 and collecting dust.

[0030] Specifically, when installing the collection frame 13, simply pull the lever 14 and insert the collection frame 13 into the outer casing 1. After installation, release the lever 14, and insert the limiting block 17 into the limiting groove 18 via the spring 15 to complete the installation. The scraper 11 is made of rubber, and a telescopic plate is provided on the lower side of the linear motor 10. The two ends of the telescopic plate are fixed to the scraper 11 and the inner wall of the outer casing 1, respectively, to prevent dust from entering the linear motor 10. By controlling the scraper 11 to scrape and collect the dust on the filter plate 4, it can automatically clean impurities, reduce manual maintenance, prevent dust accumulation and clogging of the filter screen, ensure smooth air intake, maintain efficient operation of the mechanism, and prevent dust from scattering and causing secondary pollution. It is suitable for use in multiple environments.

[0031] Working principle: First, the refrigerant circulation mechanism 2 inside the outer casing 1 draws in external air through the air inlet, filters the air through the filter plate 4, and discharges cold air through the upper air outlet and hot air through the rear air outlet and heat exhaust pipe. When it is necessary to clean the filter plate 4, the linear motor 10 is started to drive the scraper 11 on the outer wall to move, clean the outer wall of the filter plate 4, and sweep the dust into the collection frame 13 for collection. When it is necessary to handle the dust, simply pull the lever 14. 4. Drive the transmission rod 16 to rotate, and drive the limiting block 17 to move downward. Remove the limiting block 17 from the limiting groove 18, release the limitation on the fixed handle 12 and the collection frame 13, and the collection frame 13 can be taken out for dust treatment. When it is necessary to disassemble the filter plate 4, simply rotate the threaded rod 5. The threaded rod 5 drives the sliding frame 6 to slide outward, and through the rotating rods 7 on both sides, pull the locking blocks 8 on both sides downward. The locking blocks 8 are taken out from the locking groove 9, and the filter plate 4 and the connecting plate 3 can be taken out forward to complete the disassembly.
