[0034] A fixed pipe 4, the fixed pipe 4 is fixedly connected to the inner walls of both sides of the filter box 1;

[0035] The trachea connecting block 5 is slidably connected to the fixed pipe 4;

[0036] The installation assembly is provided with two groups, each group of the installation assembly includes a fixed card slot 3, a card block slot 8, a spring slot 9, a fixed card block 10 and a fixed spring 11, the card block slot 8 is opened at one side end of the trachea connecting block 5, the spring slot 9 is opened at one side inner wall of the card block slot 8, the fixed card slot 3 is opened at one side inner wall of the insertion slot 2, the fixed card block 10 is slidably connected in the card block slot 8 and the fixed card slot 3, and the fixed spring 11 is fixedly connected to one side inner wall of the spring slot 9 and one side end of the fixed card block 10;

[0037] The connecting air pipe 6 is fixedly connected to the air pipe connecting block 5 and matches with the fixed pipe 4 .

[0038] In a specific embodiment of the utility model, the filter box 1 is a filter frame before the compressor intake. The filter box 1 transports the refrigerant from the evaporator or condenser to the compressor. The fixed pipe 4 is the front and rear connecting pipes of the compressor. The air enters the air-conditioning compressor 20 through the fixed pipe 4 for compression and refrigeration. The connecting air pipe 6 is connected to the front and rear of the fixed pipe 4 during installation. The connecting air pipe 6 has the same diameter as the fixed pipe 4. The connecting air pipe 6 is an air filtering step added to the device and can be replaced at the end of the filtering work. When installing the connecting air pipe 6, the air pipe connecting block 5 with the connecting air pipe 6 is directly inserted into the insertion groove 2. When the fixed card block 10 moves downward, it contacts the inner wall of the insertion groove 2. The contact surface of the fixed card block 10 and the insertion groove 2 is an inclined surface. The insertion groove 2 squeezes the fixed block 10 to slide into the block groove 8 and squeezes the fixed spring 11 to shrink, until the air pipe connecting block 5 is inserted into the bottom of the insertion groove 2, the connecting air pipe 6 is connected to the fixed pipe 4 to filter the air while guiding the air, and after the air pipe connecting block 5 slides to the bottom of the insertion groove 2, the fixed spring 11 that was squeezed and shrunk before rebounds, pushing the fixed block 10 into the fixed slot 3, so that the fixed slot 3 clamps the fixed block 10 and the air pipe connecting block 5 to complete the fixation of the air pipe connecting block 5, and pressurizes an air filter device in the intake stage of the air-conditioning compressor assembly, so that the on-board air conditioner of the new energy bus can filter the exhaust gas discharged by other cars on the road when cooling the air, to ensure that the output cold air in the car does not contain pollutants.

[0039] For details, please refer to Figure 1-Figure 4 Two filter cotton pads 7 are fixedly connected to the connecting air pipe 6, and a plurality of filter holes 17 are formed on the surfaces of the two filter cotton pads 7.

[0040] In this embodiment, the air passes through the filter hole 17 to filter the automobile exhaust impurities in the inhaled air, and the filter cotton pad 7 is arc-shaped to increase the overall contact area between the air and the filter cotton pad 7, thereby improving the filtering efficiency.

[0041] For details, please refer to Figure 1-Figure 4 A pull-out groove 14 is provided at the upper end of the trachea connecting block 5 , and a fixed pull block 16 is fixedly connected to the upper end of the trachea connecting block 5 .

[0042] In this embodiment: the pull-out groove 14 is an arc-shaped composite finger arc, the fixed pull block 16 and the trachea connecting block 5 are arc-shaped. When the filter cotton pad 7 needs to be replaced and cleaned, the operator reaches into the pull-out groove 14 and holds the fixed pull block 16 to pull out the trachea connecting block 5 and replace it.

[0043] For details, please refer to Figure 1-Figure 4 Two groups of disassembly components are provided in the trachea connecting block 5, and both groups of disassembly components include a pull rope groove 12, a disassembly pull rope 13 and a movable pull block 15. The pull rope groove 12 is opened on the inner wall of one side of the spring groove 9 and is connected to the pull-out groove 14. The movable pull block 15 is slidably connected in the pull-out groove 14, and the disassembly pull rope 13 is fixedly connected to one side end of the fixed block 10 and the lower end of the movable pull block 15.

[0044] In this embodiment: due to the elastic force of the fixing spring 11 pushing the fixed card block 10 against the inner wall of the fixed card slot 3, the disassembly pull rope 13 also moves a certain distance into the card block slot 8, so that the movable pull block 15 is pressed against the lower inner wall of the pull-out slot 14, and the fixed pull block 16 and the movable pull block 15 are misaligned. When the trachea connecting block 5 needs to be replaced, the operator holds the movable pull block 15 and the fixed pull block 16 with his fingers, and then pulls up the movable pull block 15. At this time, the disassembly pull rope 13 is driven by the movable pull block 15 to pull the fixed card block 10 out of the fixed card slot 3 to release the fixing restriction on the trachea connecting block 5. After that, the operator can pull the trachea connecting block 5 out of the insertion slot 2 for quick replacement, ensuring that the filter cotton pad 7 can be cleaned at any time to ensure the filtering efficiency of automobile exhaust.

[0045] For details, please refer to Figure 1-Figure 4 Two sealing rings 18 are fixedly connected to both side ends of the connecting air pipe 6.

The fixed pipe 4 is the front and rear connecting pipes of the compressor. The air enters the air-conditioning compressor 20 through the fixed pipe 4 for compression and refrigeration. The connecting air pipe 6 is connected with the front and rear of the fixed pipe 4 during installation. The connecting air pipe 6 has the same diameter as the fixed pipe 4. The connecting air pipe 6 is an air filtering step added to the device and can be replaced at the end of the filtering work. When installing the connecting air pipe 6, the air pipe connecting block 5 with the connecting air pipe 6 is directly inserted into the insertion groove 2. When the fixed card block 10 moves downward, it contacts the inner wall of the insertion groove 2. The contact surface between the fixed card block 10 and the insertion groove 2 is an inclined surface. The insertion slot 2 squeezes the fixed block 10 to slide into the block slot 8 and squeezes the fixed spring 11 to shrink, until the air pipe connecting block 5 is inserted into the bottom of the insertion slot 2, the connecting air pipe 6 is connected to the fixed pipe 4 to filter the air while guiding the air, and after the air pipe connecting block 5 slides to the bottom of the insertion slot 2, the fixed spring 11 that was squeezed and shrunk before rebounds, pushing the fixed block 10 into the fixed slot 3, so that the fixed slot 3 clamps the fixed block 10 and the air pipe connecting block 5 to complete the fixation of the air pipe connecting block 5, and pressurizes an air filter device in the intake stage of the air-conditioning compressor assembly, so that the on-board air conditioner of the new energy bus can filter the exhaust gas discharged by other cars on the road when cooling the air, to ensure that the output cold air in the car does not contain pollutants.
