[0002] In the traditional automobile air conditioning system, the circulation flow and pressure change of refrigerant are the core to achieve the refrigeration effect in the car. However, due to the inevitable impurities, moisture and temperature changes in the refrigerant, the automobile air conditioning system often faces the problems of ice blockage and dirty blockage. Ice blockage usually occurs at the outlet of the expansion valve or in the low-pressure pipeline, and the main reason is that the moisture in the refrigerant forms ice crystals after expansion and pressure reduction, blocking the refrigerant passage; while dirty blockage is due to the presence of particulate impurities in the refrigerant, which gradually deposits in the pipeline, affecting the circulation of the refrigerant, and in severe cases, even causing the expansion valve to be blocked and the air conditioner to fail.
[0003] The problems of ice blockage and dirty blockage not only reduce the efficiency of refrigerant flow, but also can cause damage to key components such as the expansion valve and compressor, affecting the overall performance and life of the air conditioner.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor should belong to the protection scope of the utility model.
[0020] As shown in the accompanying Figure 1 to the accompanying Figure 3 drawings.
[0021] The utility model provides a kind of anti-blocking environmental protection type automobile air conditioning pipeline, including air conditioning high pressure valve 1, high pressure connecting port 2, high pressure delivery pipe 3, expansion valve 4, low pressure delivery pipe 5, low pressure interface 6 and air conditioning low pressure pipe 7, wherein: high pressure connecting port 2 is fixedly installed in one end of air conditioning high pressure valve 1, and high pressure delivery pipe 3 is fixedly installed in one end of high pressure connecting port 2, and is connected with the input end of expansion valve 4;The output end of the expansion valve 4 is fixedly installed with low pressure delivery pipe 5, and one end of the low pressure delivery pipe 5 is fixedly installed with low pressure interface 6, and the air conditioning low pressure pipe 7 is fixedly installed in one end of low pressure interface 6.
[0022] Air conditioning high pressure valve 1 includes high pressure refrigerant pipe 11, extension cavity 12, support block 13, filter pipe 14 and filter element 15, and extension cavity 12 is fixedly installed on the outside of high pressure refrigerant pipe 11 near one end of expansion valve 4, and support block 13 is fixedly installed inside extension cavity 12.
[0023] Air conditioning low pressure pipe 7 includes low pressure refrigerant pipe 71, expansion cavity 72, drive motor 73 and dispersing blade 74, and expansion cavity 72 is fixedly installed on the outside of low pressure refrigerant pipe 71 near one end of expansion valve 4, and drive motor 73 is fixedly installed at the bottom of expansion cavity 72.
[0024] The extension cavity 12 inside air conditioning high pressure valve 1 and high pressure refrigerant pipe 11 form a cavity with upper and lower circles together, and the shape of the structure formed by support block 13 and filter pipe 14 is completely consistent with the cavity.
[0025] The expansion cavity 72 inside air conditioning low pressure pipe 7 is a spherical cavity, and the dispersing blade 74 is made of several outwardly curved steel blades, which can be rotated by the drive of drive motor 73.
[0026] The working principle of the anti-clogging and environmentally friendly automobile air conditioning pipeline system is mainly to realize stable delivery of refrigerant by filtering high-pressure refrigerant and cleaning low-pressure refrigerant, and to prevent ice clogging and dirty clogging. The specific working principle is as follows:
[0027] 1. High-pressure refrigerant filtering
[0028] The high-pressure refrigerant is pressurized by the compressor in the air conditioning system and is transmitted to the expansion valve 4 through the high-pressure refrigerant pipe 11 of the air conditioning high-pressure valve 1. In this process, the filter passage formed by the high-pressure refrigerant pipe 11 and the extension cavity 12 effectively removes impurities in the refrigerant, preventing particulate matter and moisture from causing clogging of the expansion valve. The support block 13 inside the extension cavity 12 connects the filter pipe 14 and the filter core 15, where the filter core 15 filters out impurities in the refrigerant to ensure that clean refrigerant flows into the expansion valve 4.
[0029] 2. Refrigerant expansion and pressure reduction
[0030] When the high-pressure refrigerant reaches the expansion valve 4, it is rapidly expanded and cooled by the pressure reduction effect of the expansion valve, entering a low-temperature and low-pressure state. This process delivers the refrigerant from the high-pressure delivery pipe 3 to the low-pressure delivery pipe 5, providing protection for the refrigeration effect of the refrigerant.
[0031] 3. Low-pressure refrigerant cleaning
[0032] After the low-temperature and low-pressure refrigerant passes through the expansion valve 4, it enters the low-pressure pipe 7, which is provided with an expansion cavity 72 and a dispersing blade 74. The dispersing blade 74 can effectively disperse residual ice crystals or impurities in the refrigerant to prevent clogging of the low-pressure pipeline and the compressor end. The drive motor 73 rotates the dispersing blade 74, causing it to come into full contact with the low-pressure refrigerant in the expansion cavity 72, dispersing the ice crystals and impurities, and ensuring smooth and stable flow of the refrigerant.
[0033] 4. System cycle stability
[0034] After cleaning and pressure reduction, the low-pressure refrigerant is delivered back to the compressor through the low-pressure interface 6, completing the refrigerant cycle. After being treated by the air conditioning high-pressure valve 1 and the low-pressure pipe 7, the high-pressure and low-pressure refrigerants maintain a clean and stable flow state during the refrigerant flow and cooling process, avoiding air conditioning system failures caused by dirty clogging or ice clogging.
[0035] Summary
[0036] This automobile air conditioning pipeline system ensures the purity and smoothness of the air conditioning refrigerant during the entire cycle through the filtering of high-pressure refrigerant, the dispersing treatment of low-pressure refrigerant, and the dynamic cleaning of the drive motor, achieving efficient refrigeration and prolonging the service life of the system.
[0037] The technical scheme of the utility model, or the technical scheme inspired by the technical scheme of the utility model, designs similar technical scheme, and achieves the above technical effect, and all falls into the protection range of the utility model.
